lb atlZ whom it maty concern,-
Beit knownthat I, HERBERT I. WASHBURN, a citizen of'the United States, residing at Schenectady,cou nty of Schenectady,and State of New York, have invented certain new and useful Improvements in Continuous Dining-- Room Services, of which the following is a specification.
My invention relates to apparatus for use in dining or lunch rooms, and is intended to provide means whereby customers may be quickly and continuously served and without confusion or interference with one another.
My invention is useful underagreat variety of circumstances,but is of more particular advantage in cases where the space for dining purposes is in the form of a long and more or less narrow room. Ordinarily in such cases in rush hours customers stand several deep in front of the lunch-counters,and thus cause considerable confusion and at thesame time more or less delay in the service. Moreover, the customers are apt to congregate in that part of the dining-room near the entrance, so as practically to blockade the entrance to as well as the front part of the room, and thus render the back portion of the room relatively inaccessible to newcomers, and consequently practically useless.
My invention enables the whole of the space, of whatever depth, to be advantageously utilized during heavy or light patronage, and thus increases the earning capacity of the dining-room.
In accordance with my invention I provide a continuously moving chain of chairs or seats which pass along in front of the lunchcounters, closely adjacent thereto, so that a customer seated in one of the chairs or seats is enabled as he passes along to take from the counter or counters any dishes or articles of food thereon which he'may select.
The features of novelty which I believe are characteristic of my invention I have pointed out with particularity in the appended claims. The invention itself, however, both as to its details of construction and mode of operation, will be better understood by reference to the following description, taken in connection withthe accoinpanyingdrawings, which illustrate one of the various embodiments which my invention may assume in practice.
In the drawings,Figure 1 is a side elevation of a chain of chairs or seats arranged according to my invention. Fig. 2 is a plan View corresponding to Fig. 1 and showing the relation of the chairs to the counters carrying articles of food. Fig. 3 represents, on an enlarged scale, the driving connection used betweeneach chair and the continuous driving mem her or chain for propelling or driving the chairs. Figs. 4 and 6 are views, the one in elevation, partly in section, and the other in plan, of the driving mechanism for the chain of chairs represented in preceding figures; and-Fig. 5 is a detailof modified form.
Referring now to Figs. 1 and 2, a series of chairs are shown at 1, 2, and 3 as illustrative of a continuous or endless chain of chairs or seats. In the drawings only a few such chairs are shown; but it is to be understood that any number of chairs may be used and may be spaced apart from each other at regular intervals or irregularly, if desired, and at any desired distance-from each other. The chairs are mounted so as to move about an endless track and are preferably arranged so as to move on rollers, grooved wheels, or other antifriction devices.
The track or surface upon which the chairs roll or otherwise move may be constructed in a varietyof ways and may be fashioned either of wood or of metal, as desired. In the drawings I have represented a track structure of metal-work. As shown, the general outline in plan view is long and narrow. with straight sides and rounded ends. The length may be anything desired, as I have intended to iudicat-e by the broken-away middle sections of Figs. 1 and 2. A track structure of the general form indicated is suitable for long narrow rooms. Without the aid ofmy invention such rooms, by reason of the narrow passageway afforded and the consequent relative inaccessibility of the back part of the room, cannot be efficiently used for dining-room purposes.
The metal-work construction for supporting the chain of chairs is a sort of endless girder or truss, the upper-and lower members 4 and 5 of which are formed of angle-iron and serve, respectively, as track-rails. Supporting-posts, such as at 6, with feet for securing the same to the floor are located at regular intervals along the structure and serve to support the weight of the parts and to space apart the track-rails at the proper distance. Diagonals or tie-bars, such as at 7 and 8, extend, as shown, between the vertical supports or struts 6 and hold the parts against parallel movement of the upper and lower rails 4 and 5 relatively to each other. Cross-bracesas shown in plan View, for example, at 8-give lateral stifiness to the structure, and of these as many may be provided as desired.
The angle-irons 4 and 5, constituting the track and guide rails, respectively, are arranged so that one flat side of each angle-iron is horizontal, while the other extends upwardly. The upper edge of track-rail 4 is in position to receive the grooved wheels by which the chairs are supported on the rails, while its lower corner is in position to engage with clips attached to the under surface of the chair-seat to prevent the chairs from tipping or leaving the rails. Similarly the upper edge of rail 5 is in position to engage with the flanges of the guide-wheel 18 to keep the chair in vertical position.
The construction will be readily apparent by reference to the right-hand portion of Fig.
'1, in which the track structure is shown partly cut away in order the more clearly to indicate the mode of support of the chairs on the rails.
Each of the chairsas, for example, chair 3-is provided with a seat 9, a back 10, and a single wide arm 11 of such shape and dimensions as readily to accommodate one or more plates, cups, and the like. The chair has two grooved rollers 12 secured to the seat 9 and tracking on the rail 4, one only of which grooved wheels on chair 3 shows in Fig. 1. A foot-rest and step 13 is secured, as shown, to the three legs 14:, 15, and 16 of the chair. This foot-rest has secured thereto a suitable bracket 17, carrying a grooved guide-wheel 18, engaging with the lower rail 5. The View of chair 3 shown in Fig. 1 represents the antifriction-wheels in end elevation. A front view of the wheels would be the same as the front view of the wheels 19, 20, and 21 of the adjacent chair 2.
In order to drive the chairs one after the other around the endless track, a variety of means may be employed. I have chosen for illustration, however, an endless link chain or belt 22, which at one end of the track passes around a driving sprocket-wheel 23, is supported at intermediate points by driving connections to the chairs, and at the other end passes around an idler 24:. Fig. 3 shows,
to an enlarged scale, the driving connection between the chain 22 and the bottom 25 of some one of the chairs or seats. This driving connection consists mainly of a link 26 of somewhat Z shape, with one of its parallel ends 27 pivoted to a lug or boss 28, extending from one of the links of the chain 22, and its other parallel portion 29 to a pin 30, held in place against the bottom 25 of the chair by means of a plate 31. This pin, if desired, may be integral with the plate or may be held in position by means of screws 32 33 or other securing devices. Cotter-pins 3 1 35 hold the ends of the link 26 from disengagement from the lugs 28 and 30. The point of attachment of the link to the under surface of the chairseat is chosenas shown, for example, at the right of Fig. 2so as to assist in keeping the chair on the track and so as to reduce friction between wheel-flanges and track while rounding the curves. If desired, of course, othermodesofconnection-such,forexample, as lock-nuts or the likemay be employed without departing from my invention.
It will be noted by reference to Fig. 2, attention being paid to the arrows marked thereon and indicating the direction of motion of the chain of chairs around the endless track, that each chair faces, not at right angles to the direction of motion, but partly toward the direction in which the chair is advancing, at an angle approximating fortyfive degrees. This permits the occupant of each chair as he passes in front of the counters 36 37 to observe more readily the various dishes or articles with which the counters are provided in advance of the time when his chair passes in front of them and permits him with greater ease and convenience to take from the counter or counters such dishes as he may choose or such articles of food, as the case may be.
By placing the chairs at an angle of about forty-five degrees to their direction of motion a strong and simple construction of chair may be used, as shown in the drawings. The construction is such that diagonally-located posts or legs, such as 20 and 21 in chair 2, are in a parallel line with the track and closely adjacent thereto. This mounting of the chairs has not only the advantage of greater strength and simplicity, but causes the backs of the chairs, or at least those portions of them which project over the track, each to present a pointed shape and together to form a sealloped outline, such as to permit a turn of short radius at the rounded ends'of the track, together with a close spacing of the chairs, which would not otherwise be possible.
The elevation of the supporting-track to a position close under the chair-seat provides a space for driving motor, gearing, &c.,while the closeness of the rail-tread to the center of gravity of the load permits a close spacing of the two supporting wheels. In other words, it provides a truck of short wheelbase which readily rounds curves of small radius. This is a necessary feature in obtaining a small overall width of the track structure.
The plan view of the apparatus as shown in Fig. 2 represents an organization suitable for use in long narrow dining-rooms. The counters 36 and 37 of indeterminate length are supposed to be located at one side of the room and the chain of chairs between the ICC . shaft witha beveled gear 58.
counters and the other side of the room.
- p The chain of chairs, however, extends nearer sponds to the blank space below the righthand end of Fig. 2.
The driving mechanism for the chairs is shown more in detail in Figs. 4 and 6. In
these figures the sprocket-wheel which drives.
the endless chain 22 is shown in sectional side elevation at 23; This wheel is keyed to a shaft 39, which rotates in suitable bearings formed in a frame 40,preferably of cast metal, with stiffening-ribs, some ofwhich are shown in Fig. 4, but all of them in dotted lines at 41 to 48, inclusive, in Fig. 6. The frame 40 has straight sides with one straight end and one semicircular end and is of such dimen-.
sions as to allow of its being supported by the inwardly-projecting ledge of the angle iron or upper rail 4, to which it may be fastened by the bolts, screws, or the like.
The innerside of the flange of the driving wheel 23is'provided with gear-teeth. A pinion 49 engages with the teeth of the internal gear thus formed. This pinion is driven from the electric motor 50 through intermediate speed-reducing gearing of some appropriate character. Inthe present instance this speedreducing gearing consists of a worm-wheel 51, mountedon the same shaft as the pinion 49 and meshing with the worm 52 on the shaft 53. This shaft carries the pulley 54, belted to the motor 50. The worm is mounted, as shown, in thrust-bearings, and all ofits wearing parts, together with the bearings of the shaft carrying the worm, are thoroughly lubricated'by means of oil'placed in the box or oil-pot 54.
Instead of using a Worm and worm-wheel I may, if desired, use ordinary spur-gearing arranged to have the desired speed reduction. An arrangement of gears of this sort is shown in Fig. 5, in which the shaft corresponding to the shaftcarrying a pinion 49 in Fig.4 is indicated at 55. On this shaft in place of the worm-Wheel a spur-gear 56, with a suitable number of teeth, is mounted. With this gear meshes a pinion 57, mounted on the same With this beveled gear meshes in turn the beveled pinion 59, the shaft of which may, as before, be bolted to the motor 50.
Instead ofthe forms of speed-reducinggearing shown and their arrangement in the particular organizations illustrated I may employ other suitable forms of gearing without departing from the broader features of my invention. Moreover, instead of using an electric motor for furnishing the power I may of ends.
course derive the power from any other suitable source, in which case appropriate powertransmitting mechanism, such as countershaft or the like, may be utilized; also, in very long chains of chairs it may be desirable to have a drivingmotor geared to each sprocket, thus avoiding an excessively-heavy drivingchain and heavy sprockets, gears, &c., at the Whateverdriving means be employed I may arrange the same so that the speed of the driven mechanism may, if destred, be changed from time to time.
The idler-sprocket 24, over which passes the chain 22 from the driving-sprocket 23, is shown at the left-hand side of Figs. 4 and 6, respectively. This sprocket, like the driving sprocket 23, is mounted on a shaft 55, having bearings in a flat cast-metal support 56. This support is provided with strengthening-ribs 5'7 and is of such dimensions as to fitover the inwardly-extending flange of curved angleiron track 4 at the left-hand end of the structure.
Instead of being permanently secured to the angle-iron track the support 56 is arranged so that it may be adjusted longitudinally of the track 4, as occasion may require, so as to take up the slack of the driving-belt 22 as the same lengthens or stretches during use. Adjusting-screws 60, bearing against a cross-bar 61, extending between the two parallel tracks 4, serve as convenient means for efiecting the adjustment mentioned. When the chain 22 becomes too long, the adjustingscrews 60 may be screwed into the frame or plate 62, so as to allow the latter to approach closely the cross-bar 61. The chain 22 may then be shortened by taking out one or more links, and its tension may then be readjusted by means of the screws 60. When the proper adjustment has been secured, the plate or frame 62 is clamped to the angle-iron track 4 by means of the bolts or screws 63.. The openings in the angle-irons, through which these bolts or screws pass, may be in the form of slots extending in the direction of adjustment of the frame or plate 56, so as to'permit adjustment of the frame or plate by merely loosening the screws or bolts without removing them.
It will be evident from the foregoing description that various modifications in the details of construction and in the arrangement of the particular embodiment chosen for illustration may be made without departing from the spirit of my invention, for which reason I do not wish to be limited to the exact details shown and described.
