MACHINE FOR MAKING WIRE HANDLES.

SPECIFICATION forming part of Letters Patent No. 371,492, dated October 11. 1887.

Application filed March 14, 1887. Serial No. 230.785. (No model.)

To aZZ whom it may concern:

Be it known that I, JACOB S. DETRICK, a citizen ofthe United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Machines for Making Vire Handles for Sheet- Metal lVarc, of which the following is aspeciication.

This invention relates to a machine for making loop-shaped handles, such as are used for dish-pans, colanders, saucepans, and the like. Handles of the kind referred to are made of heavy wire, and, besides being bent to the desired shape, must have their ends flattened and shaped ready for attachment to the vessel.

The invention is illustrated in the accoml panying drawings, in which Figure 1 is a top plan ofthe machine. Fig. 2 is a top plan of the reel which holds the wire. Fig. 3 is a view ofthe brake device. Fig. 4 is a vertical longitudinal section of the machine. Fig. 5 is a view ofthe flattening-die H. Fig. 6 is a side elevation of the machine. Figs. 7, S, and 9 are detail views of parts of the clutch device. Fig. 10 is an elevation ot' the side opposite that shown in Fig. 6. Fig. 1l is a section on a larger scale, showing the wire-cutting and a part of the handle-forming mechanism. Fig. 12 is a View ofa straight piece ofthe wire ent and ready to be formed into a handle. Fig. 13 shows two views illustrating the wire as bent by the first action of the machine to form the handle. Fig. 14 shows two views illustrating the result of the second action of the machine in forming the handle, whereby the ends are attcned and the final shape given it.

ln formingthehandles the straight wire a is lirstbent to a U shape, as seen in Fig. 13, by the action of a pair of dies, and while these dies are still gripping thc U-shaped wire another pair of dies produce the curve b and the fiat ends c, and also imparts thereto any desired twist. The part d serves as the hand-grasp.

My invention relates to the organization in a machine of certain parts and mechanism for operating the aforesaid dies.

The letter A designates a rectangular cast- .metal frame having a horizontal position and supported on legs B, which rest on a base, G. At cach side this frame is strengthened by oblong steel or wrought-iron hoops A. The dies are supported and moved in this frame. The two dies E and F impart the U shape to the wire, and the dies G and H curve and flatten the ends, and also give the flat ends a slight twist, as shown in Fig. 14, whereby they will lit properly against the outer side of a circular vessel.

The dies E and G are fixed to asuitablc bar or shank, l, which is stationary. has a bottom curved face, d', which is provided with a groove, cl2, extending in the direction of or with the curve of said face. This curved groove forms the inner curve of the handgrasp d of the handle. a block with a rounded or outward-curved face corresponding to the segment of a circle. The plane of the curved face of this die G is at right angles with respect to the plane of the The die E 6o The die G comprises grooved face d of the die E, and it is on this 7o The bar or shank part of the stationary' die E. The die F has 8o at its top a center concave curve, d3, which forms the outer curved part ofthe hand-grasp d, and at eac'h side of the said center curve is a straight horizontal face provided with a groove, f. Vhen the straight piece of wire a S5 is in position above the groove f on the top of the movable die F, it will be bent to the U shape by an up movement of said die. Vhen the die F has moved up, and the straight wire has thereby been bent to a U 9o shape, the dies E and F continue to hold the bent wire, while the exposed ends of said wire are acted on by other dies, now to be described.

The die H is movable, and is the counterpart of the stationary die G-that is to say,

it has a concaved face corresponding to the outward-curved face of said die G. The dies G and H act on the exposed ends ofthe U -shaped wire, which they flatten, as at c, and near the dat part curve, as at b.

' up at one side of the seat.

The foregoing description of the dies is necessary to a proper Iunderstanding of the machine.

A cam-shaft, J, is mounted in bearings in the two front legs, B, and at one end has a gear-wheel, J', which gears with and-is driven by a pinion, g, on a shaft, K, which carries a drive-pulley, K', whereby motion is imparted to this mechanism. The shaft J has a cam, h, which raises the carrier' F' of the movable U shaped die F. This die-carrier F' slides up and down in suitable vertical guides, i. As already stated, it is forced up by the action of the cam 7i, and is forced down by the action of a spring, k, bearing onan arm, k', projecting from the carrier. The top of the die-carrier F'has a seat and a flange, m, projecting The movable U- die F rests upon the said seat l, and is secured by bolts n, passed through the die into the said flange m.

A carrier, H', has a socket, o, to receive the flattening-die H, which is secured by bolts o'. This die-carrier is tted in horizontal guides p in the rectangular frame A. An eccentric-shaft, L, is mounted in bearings at theA rear end of the frame, and a rod, L', connects the carrier H' with said eccentric-shaft. The rotation of the eccentric-shaft therefore causes the die-carrier B' to reciprocate horizontally. This eccentric is driven by a pulley, L2, secured to fa balance-wheel, L3, both of which turn freely on the said eccentric-shaft L. A clutch device is on this shaft, and serves to couple the balance-wheel with the shaft. This clutch is shown in Figs. 1, 7, 8, and 9. The balance-wheel L3 has a hub, N, which is provided with two side lugs, q. The eccentricshaft L has a hub, O, keyed fast to it. This hub O has a slide-bolt, r, which is movable back and forth in a slot formed in the hub and in a line parallel with the shaft. This slidebolt r may be moved forward toward the balance-wheel hub N, and thereby engage with one of its lugs q, or maybe moved back, as in Fig. 7, and thereby be disengaged.

An upright arm, P, is attached to a lever, P', and has a vertical slot, r', which is occupied by a bolt, r2, projecting from' the side of one leg B. The bolt lr2 serves to steady and.

guide the upright arm as it moves up and down. A spring, P2, below the upright arm presses the latter normally upward. The lever P', attached by one end to the said upright arm, extends to and its free end has position" alongside of the wheel J', and said wheel has a side projecting arm, P3, which at each revolution cornes up against the free end of the said lever, and thereby raises it, and this movement of the lever draws the upright arm Pdown. i The upper end of the upright arm P, while pressed upward-engages with the I slide-bolt r and retains or holds it back, and

when said upright arm is drawn down, and thereby released from the slide-bolt, a spring, g', on the hub O presses the slide-bolt r forward,causing it to engage with one of the lugs 'tric-shaft is intermittent.

g on the revolving hub N, which engagement at once sets the eccentric-shaft in motion. In order that the upright arm P, when pressed upward, may readily engage with the slidebolt r, the latter has a central cut-away,which at one side is inclined,as at W. The hub O has an exterior annular groove, r4, and the necting-rod L',eccentricshaft L, and the clutch just described constitute the connecting mechanism between the two movable or sliding dies F and H, whereby they are actuated in proper unison.

Any known form of clutch may be used in the above combination instead of the one here described.

From the foregoing description it will be seen that the rotary movement of the eccen- In order to check and stop its movement,a brake, Q, isprovided.

(SeeFigs. 1, 3, and 10.) The brake consists of a'block, Q, on a pivoted arm, Q'.` This block is in position to bear on an eccentric brake-wheel, Q2, secured to the end of the eccentric-shaft L. An adj usting-screw, s, below Yrco the pivoted arm serves to support the latter at the desired fposition. As the brake-wheel Q2 is eccentric, the brake-block Q will take effect on it only during about one-half ofits revolution. The parts are so arranged that when the die-carrier H is being forced forward toward its counterpart G the brake will not at that time be applied; but upon the said diecarrier .H' beginning to move back, then the brake will take effect.

The wire a, from which the handles are to be'made, is preferably coiled and supported on a reel, R, (see Fig. 2,) from which it passes to and through a set of straightening-rollers, and thence to the machine. straightening-rollers are employed.l The first series, S, turn in a horizontal plane, and the intermittent feed motion consist of a ratchetwheel, u, keyed fast on the upper feed-shaft, t, and pinion u', loose on said upper feed-shaft, The pinion 'zo' has a hub, u', to which an arm,

IIO

Two series of a3, is attached. This arm u is alongside of the ratchet-wheel u, and carries at its end a spring-pawl, o, which engages with the teeth on said ratchetwlieel. A rotary forward and back motion of the loose pinion a' throws the pawl-arm a3 first forward and then back, whereby the ratchet-wheel u and both feedrollers T have only a forward movement,which movement is intermittent. The means forimparting a rotary forward-and-back motion to the loose pinion a' comprises the following parts: a vertical rack-bar, U, which is engaged with the said loose pinion and is fitted in upper and lower guides, U' and U2, so as to slide therein up and down. A vertical reciprocating movement is given to this rack-bar by a lever, V, pivoted to a fixed standard at w, and connected with the said rack-bar by a link, XV, which is pivoted to the rack-bar at w'. The lever is provided with a friction-roller attached by a bolt, x, and a cam, y, on thelower shaft, J, bears on the said friction-roller and raises the lever. The gravity of the parts is suftlcient to lower the rack-bar. As the extent of movement of the rack-bar determines the length ofthe wire which is fed to the dies by each movement of the feed-rollers T, it is important to be able to regulate the movement of said rack-bar. This is done by an adjustable connection between thelink WV and lever V, whereby the connecting-pivot z may be placed nearer to or more remote from the lever-pivot w. Obviously the nearer to the lever-pivot w the link-connecting pivot .c is placed the shorter will be the up-and-down movement of the rack-bar. In the drawings the free end of the lever V has a longitudinal slot, wt, and the connecting-pivot z is attached to a block which is movable'in the said slot. A screw-bolt, w3, regulates the position of the pivot-block. It will thus be seen the connecting-pivot e is adjustable lengthwise on the lever.

A suitable opening is necessary in the side of the frame A for the entrance of the wire a. from the feed-rollers T to the dies. I provide an adjustable feed-tube, T2, which passes horizontally through an opening in the side 'of the frame A. This tube may be moved endwise,so that its end which is within the frame may project more or less inward beyond the framewall. A screw-threaded bolt, l, has one end rigidly secured in the side of the frame A,and projects therefrom parallel with the feed-tube, the outer end of which has a lateral arm, 2, provided with a hole. Thesaid projecting` bolt l occupies the said hole, and thereby the lateral arm is movable along the bolt. Two jamnuts, 3, on the said bolt-one each side ot' the lateral arm 2-retain the arm and consequently the feed-tube wherever set. The feed-tube TZ must be adjusted in connection with the shearplate 4, in order to cnt the proper length of wire for the partioularsized handle that the machine may be set to make. The shear-plate 4 sets on the die-carrier seat Z, and a bolt, 5, secures it to the flange m.

It will be readily understood, though not shown in the drawings, that if the bolt 5 passes through a horizontal slot in the flange m the shear-plate 4 may, by loosening and tightening the said bolt 5, be laterally adjusted toward or away from the die F. Both the feed-tube T2 and the shear-plate l must be adjusted alike, so as to preserve the same relative position with respect to cach other, it being understood that the cutting of the wire is done by the shear plate passing up close alongside ot' the inner end ofthe feed-tube.

A rod, 6, passes horizontally through the lower part of the shank I, and a stop-plate, 7, has one end adj ustably secured on said rod,and the other end projects to a position opposite the end of the feed-tube, whereby when the feed-rollers T force the wire a through the feedtube and between the dies E and F the end of the said wire will come in contact with the said stop-plate 7, whereupon the latter will prevent the admission of anyv more wire.

By means of the adjustable feed-tube T2, shear-plate 4, and stop-plate 7, several different lengths of wire may be cut'to suitas many different sizes of handles. The several dies may also be readily changed for others ofthe sameJ kind,larger or smaller, and thus the one machine is adapted to make several handles of different sizes.

An inclined delivery-slide, S, receives the iinished handle as it drops from the die upon the carrier F' moving down.
