HOOP- COILING MACHINE.

SPECIFICATION forming part ofjLetters Patent No. 223,968, dated January 27, 1880.

- Application filed July 10, 1879.

To all whom it may concern:

Be it known that I, ALEXANDER F. WARD, of Ohatham, in the county of Kent and Dominion of Canada, have invented an Improvement in Hoop-Coiling Machines, of which the following is a specification.

The nature of my invention relates to new and useful improvements in that class of machines employed in coiling hoops for shipment; and the invention consists in the construction of the several parts and their arrangement and combinations, as more fully hereinafter set forth.

Referring to the drawings, Figure 1 is a perspective view with the gate thrown open. Fig. 2 is a horizontal section through the center. Fig. 3 is a perspective of the inner face of the head and attachments to the end of the hollow shaft. Fig. 4: is an elevation enlarged and with the gate removed. Fig. 5 is an enlarged detail, showing the spring finger or dog which confines the end of the hoop first fed into the machine. Fig. 6 is aside elevation.

Like letters indicate like parts in each'figure.

In the accompanying drawings, which form V a part of this specification, A represents the frame of the machine, which carries the working parts thereof, and upon it is journaled, in suitable boxes at, the hollow shaft 1), upon the end of which is secured the hollow head 0,

the rim of which is finished upon the outside like a smooth pulley, to which motion is communicated by the friction-pulley d, which is secured to a counter-shaft, e, which runs in the shorter arm f of the lever g, by means of which .thefrietion-pulley is thrown into or out of engagement with the outer face of the head, as

desired. This lever is fulcrume'd on the rod h, and upon the counter-shaft is another pulmotion in boxes 0 on the frame, near the rear end, while their front ends pass through the front of the frame, as shown in Figs. 1, 2, and

6. To the front end of one of these rods is hinged, at p, the gate 0, which, when closed, engages with the other rod, and is secured by the spring-1atch s. The rear ends of these rods a pass through the yoke t, in which they are made adjustable by means of the setscrews a. To the center of the yoke is adjustably secured, by means of the screw or threaded end and nut c, the shaft w, which passes through the hollow shaft 1) and head c, and upon its end is rigidly secured the spider as with three arms, as shown in Fig. 3, each arm terminating in right-angle projecting studs 2. Motion is communicated to this shaft to from the head 0 by the engagement of the. studs l with the arms of the spider no, as shown in Fig. 3.

At one end of the yoke tthere is pivoted, by means of the set-screw a, a connecting-rod,

a, the opposite end of which is pivoted, by a,

suitable wrist-pin, to the crank b, which is rigidly secured to the rock-shaft c. To the opposite end of the yoke t there is pivoted, by means of the set'screw a, a similar connecting-rod, d, the front end of which, by a suitable wrist'pin, is pivoted to the bell-crank e, which is rigidly secured'to the opposite end of the rock-shaft '0. These connecting-rods and cranks are so pivoted together and arranged with relation to each other that when the yoke is retracted, as shown in Fig. 6, it cannot he accidentally projected, as the pivotal connection at one end of the connectingrodsis below the point of pivot on the yoke, so that one looks the other.

To the bell-crank e is pivoted the connect ing-rod. f by means of the wrist-pin g. The lower end of this rod f is pivotally secured to the shorter arm h of the treadle t". This .treadle is secured to the rock-shaft 7c, and to 0 its longer arm l is secured the counterbalance weight m. Pressure upon the treadle will project the yoke and gate with their attachments, and, the pressure being relieved, the weight on will retract the same.

The points of connection between the weight and .treadle and the rock-shaft and between the cranks of the rock-shaft and the yoke t are so adjusted that when the weight strikes the floor in moving the door back to place I00 against the coiling-barrel the cranks will have moved a short distance below their centers,-

outer ends are just within the front face of the disk. To this front face is secured the annular ring or short barrel 0, with a short segment cut out, as at r. A clutch-finger, p, is secured to the front face of the disk by means of the set-screw s, which passes through the slot t through said finger. A lever, a, is pivoted through the disk, so that its outer end projects through the same and enters the slot '0 in the clutch finger or dog 19, and its opposite end engages with the squaredfside of the spider-head to, so that when the latter is retracted with the yoke the lever will compel the dog to perform the function for which it is designed, and when the yoke and its attachments are projected the lever will release the dog. A leaf-spring, 00, one end of which is rigidly secured at y, engages with the notch z on the side of the dog, to hold the same upon its movable fulcrum, made by the slot t and set screw 8, and allows the dog to act upon thinner or thicker hoops as they may be presented. Thecrank B is pivoted through apro jection, O, of the frame, and has an arm, D, rigidly secured to it, at the lower end of which is fastened the weight E. To this crank is removabl y secured the band F, which passes under the ring or barrel 0, and its opposite end is removably secured toa swinging support, G, pivoted to the front of the frame. A vertical rod, H, has a reciprocating motion in bearings I in the front of the gate r. A coilspring, K, through which said rod passes, is so arranged as to keep the rod elevated, except when depressed by pressure upon thefootpiece L. The upper end of this rod is bent backward to form a detent, M, for the purposes hereinafter described.

In practice, with the machine constructed as above, the yoke, with its attachments, is retracted, as shown in Fig. 2, with the gate closed. The end of a hoop is inserted through the cut-away portion of the ring or coiling-barrel between the inner edge thereof and the point of the dog, which gives upon its movable fulcrum to receive the end of the hoop presented. Themachine is then started, when the hollow head commences rotating, its studs engaging with the arms of the spider, compelling the shaft 20 to also rotate, .whenthe projections or studsz of the arms of the spider are presented through the holes in the disk, which is secured upon the studs 1, and is thereby caused to rotate, coiling the hoop on the outside of the annular ring or coiling-barrel, against which it is held by the band F, the proper tension of which is secured by the weight E upon the arm, which secures said weight to the crank B, to which one end of the ban d is secured. The lap of the next hoop presented is inserted under the end of the coiled hoop, and so the next, until the roll or coil of hoops is as large as required, when pressure upon the foot-rest L compels the bent end or hook M of the rod H to rest upon the free end of the last hoop coiled and hold it until it is nailed. Then pressure upon the treadle 4." will project the yoke t, with its attachments and gate 1*, to the front, when the studs 2, projecting through the coiling-disk m, will force the coil of hoops from the ring or coiling-barrel, and such coil will then drop to the groundthrough the space between the gate and disk caused by projecting the yoke and its attachments, which at the same time disengages the spider-head w from the lever u, thereby releasing the dog. The yoke and its attachments are then retracted by relieving the pressure on the treadle, and the machine is in readiness to coil another roll of hoops. Should a hoop break in the process of coiling, the gate should be thrown open, as showninFig. 1, after releasing the spring-latch s, when the broken hoop is easily removed.

The adjustability of the yoke upon the side rods and center shaft will allow the machine to be employed in coiling hoops of different widths.

I am aware of the patents granted to J.

Tomlinson and J. H. Ward, and numbered,

respectively, 159,289 and 209,735, and hereby disclaim the same.
