GOINVEYER.

Application filed November 23,1911.

To all whom it may concern Be it known that T, O'r'ro EIOK, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Conveyers, of which the following is a specification.

This invention relates to conveyers, and particularly to a conveyer designed to receive bottles from crates or in large numbers and to discharge the same in single file in an upright position, ready to be fed to some other machine.

One field of utility of the device is in bottling works, where the conveyer may be used to receive bottles in crates from the bottle washing machine and to deliver the bottles discharged from the crates in single file at the appropriate rate of speed to the filling and corking devices.

A preferred embodiment of the invention will be described in connection with the accompanying drawings, wherein Figure 1 is a plan view of the complete device; Fig. 2 is a side elevation thereof; Fig. 3 is a longitudinalvertical section on an enlarged scale of the driving and discharge end of the conveyer on the line 3-3 of Fig. 1; Fig. 4 is a section on the line 14 of Fig. 1; Fig. 5 is a section on the line 55 of Fig. 1; Fig. 6 is a plan view of a portion of the agitator bars designed to show the mode of guiding these bars; Fig. 7 is a section on the line 77 of Fig. 6; Fig. 8 is a section on the line 88 of Fig. 6; and Fig. 9 is a section on the line 9-9 of Fig. 1.

The mechanism is supported on a frame work consisting of uprights 1, carrying longitudinal side bars2 and 3, suitably tied together and braced to carry the necessary mechanism. The upper bars 3 are of bar iron or steel while the lower bars 2 are of angle section, the arms of the angles extending inward and assisting in supporting the conveyer belt as will later appear. The side bars 2 are further tied together by cross sills 4 upon which are fastened a number of longitudinal slats or bars 5 spaced short distances apart. These serve as a bed or support for the conveyer belt.

At one end of the machine is mounted an electric or other motor 6 which drives a conveyer belt pulley 7 through a reducing train of gears 8, 9, 10, 11, 12 and 13, whose size and the number of whose teeth is dependent Specification of Letters Patent.

upper run of the conveyer belt 17 rests upon the slats 5 and the inwardly extending flanges of the bars 2, while the lower run is supported on rollers 18. The various parts are usually so designed that the belt 17 has a lineal speed of approximately 25 feet per minute in the direction of the arrow in Fig. 1. The belt is preferably made of a rubber covered fabric to withstand the effects of water and abrasion.

At the left hand end of the machine, as viewed in Fig. 1, which is the receiving end, are located the devices for loading the bottles upon the conveyer shown in detail in Fig. 9. These consist of shelves 19 having flanges 20 extending at right angles therefrom, the shelves 19 being pivoted at 21 so as to swing down and overlie the belt. The bottles 23 generally come to the conveyer from the washing machine in crates of the general form illustrated at 22 (Fig. 9) and are placed upon the shelves 19 as illustrated in full lines in Fig. 9. The shelves with the bottles supported thereon are then swung down over the belt to the position shown in dotted lines in Fig. 9, and the crate 22 is then moved longitudinally in the direction of motion of the belt 17 until the bottles 23 contained in the crate rest upright upon the belt, whereupon the crate is lifted vertically away from the bottles and returned to the bottle washer. In this manner the bottles are placed upon the conveyer belt standing upright in groups and are fed by the belt toward the discharge end of the machine. In order to arrange the bottles in single file it is necessary to break up this grouped arrangement and to avoid any tendency for the bottles to jam together as they are moved toward their new arrangement. To accomplish this purpose, I make use of what I shall term agitator bars and a pair of feed belts which will now be described.

Connected to the bars 2 and 3 near the middle of the machine is an upright frame 2 1 which supports a cross shaft 25 carrying a pulley 26 which is driven by a belt 27 from a pulley 28. The pulley 28 is mounted on the counter-shaft with the gears 11 and 12.

Any equivalent drive mightbe substituted. The cross shaft carries a spur gear 29 and a pair of bevel gears 30. The gear 29 meshes with a gear 31 carried on a second cross shaft 32 also supported on the frame 24 and carrying a pair of cranks 33. The cranks 33 are connected by rods 34 to journal pins 35 carried on the agitator bars-36. These bars consist preferably of an angle bar 37 carrying a vertical metal plate 38 faced with rubber 39. The agitator bars are supported throughout their entire length on bars extending between the side bars and one of the cross sills or frames 4, the supporting members 40 and consequently the agitator bars, being arranged to converge in the direction of motion of the belt L in motion, a longitudlnal reciprocatlon and serve first 17. The agitator bars thus serve to guide the advancing bottles to the middle of the belt and permit them to pass on one at a time. The agitator bars are held to their supports 40 by studs 41, which are fast in the supports 40 and extend through longitudinal slots 42 in the angle-bars 37, as clearly shown in Fig. 6. In this way the agitator bars are capable of a limited longitudinal movement. In order to reduce the friction which might be occasioned .by the jamming of bottles between the awo agitator bars, roller bearings 43 are provided to receive this thrust and relieve the studs 41 thereof.

From the mechanism above described it will be observed that when the machine is the agitator bars 36 are given to guide the bottles in a constantly narrowing path and second so to partially rotate or oscillate the bottles as they move toward the narrow end of the path as to facilitate their assuming their new arrangement. The

two cranks 33 may be parallel or opposed, or arranged at any other angle as may be found desirable, the effect of changing such arrangement being to change the relative movements of the two agitator bars. The bottles are therefore discharged from the narrow end of the agitator bars in single file. Upon leaving the agitator bars the bottles are gripped by a pair of opposed belts 44. These belts are preferably of rubber coated fabric and are supported on driving pulleys 45 and idle pulleys 46 whose bearing boxes 47 are adjusted to vary the tension on the belt. The driving pulleys 45 are carried on vertical shafts 48 mounted in bearings in the frame 24 and are driven through bevel gears 49 by the bevel gears 30 heretofore mentioned.

As indicated in Fig. 1, the belts 44 are sustained by fixed backing strips 50 so that the belts shall maintain constant gripping action on the bottles passing between them. The belts 44 move at the same speed as the main conveyer belt 17 so that as fast as the bottles are discharged from the narrow space between the ends of the agitator bars they are gripped by the belts 44 and fed to the discharge end of the machine whereadapted to direct the bottles into a singlefile arrangement, an agitator mechanism adapted to impart partial rotation or rotary oscillation to the bottles to cause them to free themselves from any cramping tendency while passing through the converging guides, so that they readily rearrange themselves as they move along on the conveyer belt, and a discharging feed device to force the bottles from the machine in their new single-file arrangement. The agitator device mayassume forms varying somewhat from that shown, the essential feature being a capability of engaging and imparting a rotary motion or a rotary oscillation to the bottles as they pass through converging guides to cause them, without cramping, to assume the arrangement desired.-
