IMPROVEMENT lN BROOM-WINDING MACHINES.

Specification forming part of Letters Patent N 0. 222,141, dated December 2, 1879; application filed August 18, 1879.

To all whom it may concern Be it known that I, CHARLES E. LIPE, of Syracuse,in the county of Onondaga and State of New York, have invented a new and valuable Improvement in Broom Winding Machines; and I do herebydeclare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, makinga part of this specification, and to the letters and figures of reference thereon.

This invention relates to that class of winding-machines that require two operators on each machine-namely, the feeder, who stands in the rear and prepares the several layers of corn in proper quantities for each broom, and the winder, who. stands in front and places the prepared corn on the handle to form a broom; audit consists in certain devicesforreceiving and carrying the corn from the feeder to a position in front of the winder, and retaining it there in convenient shape until the winder applies it to the broom; also, in certain improvements for guiding the corn from the receiver directly 011 the handle and under the binding-wire, without being detached and applied in handfuls, as has been necessary in .all machines hitherto in use for this purpose;

also, in improved spotting devices, for spotting the covers as they proceed from the feeder to the Winder; also, in an improved chuck for holding the handle firmly in the barrel while the. broom is being built up.

In the annexed drawings, Figure l represents a side elevation of my improved machine; Fig. 2, a plan or top view; Fig. 3, a sectional view of the spotting and carrying devices, taken on the line as at, Fig. 1. Figs. 4 and 5 are enlarged views of the receiver and bridge. I Figs. 6, 7, and 8 are detail views of corn'spear after passing the spotter.

A A represent the frame of my machine, which is preferably made of cast-iron, and supports in front the hollow mandrel or broombarrel B, which is fitted with a pulley, O, and chuck, to receive and hold the broom-handle. The main or driving shaft 'D is journaled to the frame near the floor to insure steadiness of motion, and, with proper pulleys and beltjaws to receive their pivot ends.

ing, it gives motion to the barrel B, the spot ter-shaft E, and carrier-shaft F, power being applied to the pulley G.

The carrying and receiving devices are supported fromone side of the machine sufficiently far away to allow the free passage of the corn, and will now be described.

The carrier or conveyer consists of an endless belt, H, upon which are arranged two rows of spurs, (t a a and a a 0/. This belt wraps around pulley H fast on the shaft F, and around a similar pulley, H running loose in a proper support, I), secured to the casting I. Motion is imparted to the carrier-belt in the direction of the arrow by means of the belt J and pulley j. The casting I projects from the frame outward between the pulleys H and H to the outside edge of belt H, and forms a backing to said belt springing away from the corn along the receiver.

The receiver consists of two flexible metallic strips, 0 c, which extend along the under side of the belt H between the rows of spurs a and a. The upper strip, 0, is secured in the rear at c to a part of the casting I, and in front at 0 also a projection from I. The lower strip, 0, is fastened in the rear to the table K, and rests 011 a piece 'of rubber tubing, (1, or other elastic substance, the front end being free and bent down over the end of tube d, as shown. A receptacle is thus formed open at both ends, through which the several layers of corn forming the broom may be transmitted in succession, subject only to the friction produced by the pressure of its flexible sides, and which holds it at any point along its path.

The tube 01 rests in a grooved strip, d, said strip being supported on brackets e e secured to the frame'A. g

Directly in front of the receiver are pivoted two fingers, L L, in a casting, l, fitted with is fastened to the front end of d. The fingers in their normal position extend forward, their free ends resting on the broom-handle It, thus forming a bridge from the receiver to the handle, over which the corn is brought down underneath the binding-wire. When not in use they are thrown back to the vertical poto keep it from in its passage This casting sition, as, shown by the dotted lines, resting against the receiver. These fingers may be arranged to slide back out of the way under the receiver, instead of swinging up, as described. I have used them made in this way, but prefer the plan shown.

The spotting mechanism is for the purpose of removing a portion of the stalk of the covers. A single cover with the stalk properly cut is shown in Fig. 9. This mechanism consists of an endless belt, M, having a series of knives, m m, fastened to it at proper intervals, running in the direction of the arrow over the pulleys f audf. The driving-pulleyf is fast on the shaft E, and derives its motion from the quarter-twist belt 9, running over pulley g (which is also fast on E) from pulley g on the driving-shaft D. The outer pulley f is journaled to the free end of a vibratingarm, N, which swings free upon the shaft E. Said arm N is limited in its upward movement by striking an adjustable stop, 1', and downward by the projection 7c striking the frame A.

A rod, 0, connects arm N with a foot-treadle, O, pivoted to the frame at 0, and extending to the rear convenient to be operated on by the feeder. When the treadle is depressed the arm N is thrown up against the stop i. The upper part of the belt M is horizontal and cuts across the path of the corn coming along the receiver. The stop 41 is made adjustable,

so that much or little may be trimmed off the stalk as may be desired. The under surface of the casting I prevents the stalks from lifting away from the spotting-knives.

The object of the vibrating arm N is to allow the spotter-belt to drop away from the path of the moving corn, when the hurl or outer covering of the broom is passed along the receiver, which will be hereinafter more fully explained.

The chuck for holding the handle in the barrel is shown in detail in Figs. 6, 7 and 8. It consists of three loose jaws, a n n, with both ends beveled, as shown. One end of the jaw is inserted in a short slot in the end of the barrel, the end of the slot being beveled corresponding] y. The other end 'of the jaw bears against one end of a similai' ly-beveled slot in the sleeve P, the jaws being held in position with a tendency to open by a rubber ring, 1), resting in notches cut in the jaws, as shown. A longitudinal movement of the sleeve toward the barrel causes the jaws to move bodily toward the center, the pressure being equal upon both beveled ends. To effect this movement, which requires considerable force to hold the broom-handle securely, an abutting ring, 1, is bolted to the frame near the bearing b concentric with the barrel and sleeve. The inside face of this ring is made into aspiral cam. A similar cam, R, provided with a hand-lever and turning loose upon the sleeve P, is placed between the flan ge 19 and ring It. These cams are so arranged that by turning the lever toward the operator, the sleeve is forced along the barrel, and the jaws tightened upon the broom-handle. A collar, (1 upon the barrelprevents it from moving longitudinally with the sleeve. The jaws prevent the sleeve from turning on the barrel with which it revolves. It will be observed that this arrangement creates considerable friction between the flange p and lever R; also between the collar 01 and bearing. This is desirable, as it prevents the barrel from turning back when not in motion.

The treadle T and tightening-pulley t are arranged to tighten the loose belt T when it is desired to move the barrel. The building up of the broom requires short intermittent movements of the barrel completely under control and .subject to start and stop at the will of the operator; Practice has demonstrated this to be a very efficient device and admirably adapted to the purpose. Almost any speed may be obtained on the barrel by gaging the pressure on the treadle and allowing the belt to partially slip over the pulleys. The wire or cord is brought down from the reel S, under the guide-pulley s, which is free to move along and turn. upon the shaft F to the handle, passing between the fingers L L. The requisite amount of tension is obtained by the use of a convenient frictiorrbrake, a device common to all winding-machines, and therefore not shown in drawings.

The underwork, or that part of a broom immediately around the handle, is composed of inferior corn and usually put on in three handfuls. A support, S, having cavities for holding this corn, (shown in dotted lines in Figs. 1 and 2,) is upheld on a standard secured to the floor in a convenient position for the winder to reach, and is filled by the feeder, who steps around to the side of the machine for that purpose. All the different grades of corn used are held in racks convenient to the reach of the feeder.

The operation of the machine is as follows: The winder, securing a handle in the chuck, attaches the wire and reaching to the support S transfers in succession to the handle the bunches of underwork placed there by the feeder. During this operation the bridge L is thrown up to the dotted position out of the way. The shoulder of the broom is nexttrimmed, when it is ready for .the covers. While the underwork is being put on the handle, the feeder selects the proper quantity of covers for a broom,,lays them on the table K, properly adjusted lengthwise, and pushes them forward between the strips 0 0 until the spurs on the conveyer, which is traveling in the direction of the arrow, catches them and transports them along to the front. As each succeeding spear arrives at the point e where the spurs leave it and pass up over the pulley Hit is pushed forward by the one following it, the last remaining at this point, the space from this one point to the end of the receiver being long enough to hold covers enough for one broom. These covers may be fed into the receiver singly or in handfuls as the feeder may choose,

provided they do not overlap each other. As they enter the receiver the feeder raises the spotter by pressing on the treadle O, which spots the moving covers and falls away by its own weight when the covers have passed and the treadle is released. The covers now-restin the front end of the receiver in a continuous sheet. The winder reaches forward and pulls either a part, or all of them if he be sufficiently expert, forward, striking the bridge L, which is thrown down upon the handle and broom, as shown. The bridge thus formed supports the covers on their way to the broom, being held down upon it by the wire. As the covers approach the handle the barrel is set in motion and the covers pass off the end of the bridge onto the handle securely bound by the wire. The wire and bridge form what may be termed a contiuuationof the receiver, the wire corresponding to the upper strip, a, and the bridge to the lower one, o.

While the winder is putting on the covers the feeder is preparing the next layer of corn,

generally hurl, which is passed through the receiver in the same manner as the covers, but without being acted upon by the spotter.

The action of the spotter, instead of being arbitrary as in all other machines using spotting mechanism, is made subject to the will of the operator, thus affording facilities for a greater range and variety of work than has beenhitherto practicable on this class of machines.

The hurl being applied to the broom in the same manner as the covers, the bridge is thrown back and thebroom finished in any desired manner. In the mean time the feeder is filling the support S with under-work and the receiver with covers for another broom.

Some of the advantages of these improvements may be summed up as follows: The couveyenbelt being always in motion, it is always ready to take corn from the feeder and deposit it in front of the winder without further looking after. In all machines using carrying belts that move intermittingly, the winder, when hecomes to put on the corn, will often find it out of his reach, when he must stop and move or cause it to be moved into position, thus losing a portion of his time which should be employed in his legitimatework. The combination of a receiver or device for holding the prepared corn with a bridge for conveying it directly on the handle, is an entirelynew feature in winding-machines. The essential principle involved is, that the corn does not leave the control of some fixed portion of the machine. In all other machines the operator has to remove the corn eutirely from the carrying devices before applying it to the broom. A great saving of time is hereby gained with the additional advantage that it requires less skill to operate, being more nearly automatic. The movable spotter allows all kinds of corn to be fed through the same conveyer, only operating at will. It also spots the covers from the under side, the side which is placed next the handle. All other spotting devices operate from the upper side, thus necessitating turning the spotted corn all over before it canbe applied to the broom.

The foot-treadle and tighteningpulley, although an old mechanical movement, is believed to be new in its application to this class of machinery.

Ha'ving thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the carrying-belt H with the corn receiving and holding strips 0 0, one above the other, substantially as described, and for the purpose set forth.
