QPECIFI'QATION forming part of Letters Patent No. 308,888, dated December 9, 1884. I Application tiled April 25, 1382. Renewed Febrnary15,1884. (No model.)

Columbus, in the county of Franklin, State of Ohio, have invented a new and useful Improvement in Machines for Making Brooms, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a side elevation of my improved broom-machine. Fig. 2 is a plan or top view through line of Fig. 1, showing the bed of the machine. Fig. 3 is a front View of the upper part of the machine. Fig. 4 is an isometric View, with part cut away, showing arrangement of bed guideway and mechanism for operating the Wire benders and clinchers.- Fig. 5 is an enlarged perspective view, partly cut away, showing construction of the device for bending and clinching the wires on the broombrush.

Fig. 7 is an end 'view of guide-bed and boxing for the bending and clinching device through line Z of Fig. 1. Fig. 8 is a rear end view of the complete machine, showing construction of the compressing-levers. Fig. 9 is a perspective view of the lower clamp or die, in the groove of which the binding-wires are laid preparatory to placing the broom therein. Fig. 10 is a perspective View of the upper and lower clamps or dies,with a broom compressed between and the projecting ends of thebinding-wires crossed by the bending-fingers; and Fig. 11 ahorizontal sectional view of thearm or standard of the machine through line g of Figs. 1 and 3.

The object of my invention is to provide a machine for manufacturing the wire-bound brooms for which I have obtained Letters Patent. Said brooms consist in having wires laid across the straw of the broom and bent around and clinched on the opposite sides to hold the straw, instead of sewing the broom, as is usually the case. The design in this machine is to clampthe broom between suitable dies and afterward to bend and clinch the protruding ends of the tie-wires around the straw.

The invention consists in having an upper and a lower die, which, when placed together,

form within the exterior shape of the broom. The lower die is secured permanently in one position to the bed-plate, and the upper die is secured to a plunger which works between guides, and is capable of being vertically moved to and from the lower stationary die. Two

'paralleltransverse grooves are formed across each of these dies to receive the tie-wires, and each die isalso provided with recesses by the sides of these grooves. of the tie-wires are then approached by suitable fingers, which partially bend the ends of the tie-rods past each other, and other mech anism is then employed to force the bent ends down on the opposite sides of the broonrstraw and clamp them firmly, all of which will now be described in detail.

In the accompanying drawings, A repre sents the base of the machine, preferably cast. At the rear end is a standard bracket or arm, B, which projects upward a suitable distance and extends forward to a point near the cen ter of the base. In the front face, 0, of this bracket is a grooved guideway, 0, preferably dovetailed, as shown in Fig. 11, to receive a dovetailed plunger, D, which slides vertically therein. 1

To provide for wear I have made the groove 0 wider than the plunger, and somewhat taporing, so that the upper end of the groove is slightly wider than the lower end. A wedgekey, D, is then inserted in the groove by the side of the plunger, and a screw or bolt, D, which passes through a bracket in the upper end of the wedge D and into the bracket, enables the operator to raise or lower said wedge and tighten orloosen the plunger in the groove. The upper end of the plunger is hinged to an arm, E, which arm extends to the rear of the machine. Centrally the arm is pivoted to a link, E,which is hinged to the machine-brack et B on top.

On the rear end of the arm E is a ball, F, which enters a socket, F, in the upper end of the vertical bar or rod G. The upper end of the rod or bar G is screw-threaded, as shown at'G, and this enters a screw-threaded aperture in the lower side of the socket'F. A nut,

, Gm may be employed to make the socket vertically adjustable on the rod G. Thelower end of the rod G is hinged to a joint, H, and

The projecting ends the opposite end of this joint has also a ball, H, which operates in the stationary socket H on the frame. The ball H is also adjustably connected with the joint H by means, of the screw-threaded part I and nut I. A vertically-disposed lever, J, is permanently attached to or cast with the joint H, and when, the plunger D is elevated this lever rests in a position near the rod G, or parallel therewith, and is held there by means of a hook, J, at tached to therod G. The rod G and joint H thus form a toggle-joint, and when the lever J is drawn forward and the pivot J is on a line with the ball-and-socket joints F H the plunger D will have reached its lowest limit, and will remain in this position until the operator desires to return the plunger. By means of the screw-threaded ends I G the limit of the plunger may be regulated. lhe lower end of the plunger D is provided with a die, L, inverted, similar tow the upturned lower die, L, as shown in Fig. 9.

The upper face, A, of the bed of the machine, beneath the head of the bracket 13, is provided with a plate, K, having itslongitudinal edges or sides K, Fig. at, beveled. The

7 interior, K, of this plateis cut away, as fully shown in Fig. at, to receive the mechanism which operates the wire-bending fingers. Centrally on this plate the lower die, L, is secured by means of bolts L through the ears L. On each side of this die is a carriage, M, adapted to haveits ends 1 embrace the opposite beveled edge of the guideway K beneath. The carriages M thus slide on the guideway to and from the die L.

The carriage is placed across the guideway at an angle equal to the angle of the side of the die L which each carriage approaches. At both ends of each carriage is a boxing, N, and between these boXings and j ournaled therein is a rocker -shaft, 0. This rockershaft has centrally an aperture, 0, which passes through from end to end to receive a plunger, P. The forward end of this plunger has a lever, P, attached thereto, and said 1everis in turn hinged to a fulcrum, P, on the boxing N, so that when the lever P is raised or lowered the plunger P will move endwise a limited distance in the rocker-shaft.

Q Q represent fingers pivoted side by side centrally to the side of the rocker-shaft O. The ends of these fingers enter suitable recesses in the rocker-shaft and embrace the plunger P. The opposite projecting ends of these fingers are crossed in the form of a pair of shears. The approaching edges of these fingers have shallow rounding grooves Q, the object of which will be hereinafter explained. The rockershaft is provided near each end with a pair of these hinged fingers, and at the points that their inner ends embrace the plunger P are inclined surfaces Q on both sides, so that when the plunger is moved inwardly the inclined surfaces Q will cause the inner ends of the fingers Q Q to recede from each other, and correspondingly cause the outer ends to approach each other. On the opposite side of the rocker-shaft 0 from the locations of these hinged fingers are stationary fingers R. These fingers project from the shaft and diverge from each other, one of them pro j ecting upwardly, the other downwardly. Two of these diverging fingers are located on the shaft at one end by the side of each other, and the other two at the opposite end of the shaft. The faces of these fingers are also provided with shallow rounding grooves It. The shaftO has at. the forward end a head or flanges, S, which projects above and below the bulk of the shaft 0, and each flange is provided with an aperture, S. The forward boxing is also provided with an enlargement, T, above the journal of the rocker shaft, through which is placed horizontally a keycatch or latch-piece, T, the inner end, T, of which is adapted to enter the apertures S of the rocker-shaft. lVhen the latch-piece T is drawn out, the shaft 0 can be turned half'way round, so that the latch will engage with the aperture S on the opposite side.

The object of turning the rocker-shaft is to enable the operator to adjust either the stationary fingers against the wires in the dies or to use the hinged fingers Q Q 011 the opposite side, as will be more fully explained hereinafter. By reference to Fig. 4 it will now be seen how the carriage M containing this rocker-shaft O is moved to and from the die L.

Beneath the die, and hinged to the plate under the die L, or to a cross-piece in the guideway K, is pivoted centrally a cross-lever, U, to the opposite ends of which, within the recess I of the guide-plate K, are hinged the links V. These links diverge from each other, the end of one being hinged to the under side of the carriage M on one side of the die L, and the other link hinged to the carriage on the opposite side of the die.

Projecting out from one side of the crosslever U is an arm, U, to which is hinged a joint, XV, and to this joint is hinged a link, W, the forward end of which projects through the side of the bed A, and is attached to an arm, X, on the horizontal shaft X 011 the outside of the bed A. The opposite end of the shaft X has a vertically-disposed lever, X". When this lever is drawn forward, the intermediary mechanism abOlG described causes the carriages M to travel toward the die L.

The dies will now be described in detail: The lower die, which for all purposes is substantially the same as the upper die, will only be described. The die is formed preferably as shown, to represent the shape of a broom. It has three depressed surfaces, to, b, and a. At the forward end is a convex surface, f, designed to receive the handle. At a point equal to one-third of the distance across the face of the die is a ridge having therein a groove, cl, and at a point equal to aboutone-half the dis- IIO tance between thisgroove and the rear end of pressions, and are designed to receive the tiewires for binding the broom.

The depressed surfaces a b 0 represent the bulge of the broom, and it is obvious that by causing the broom to receive a heavy pressure between the dies thus constituted every broom will receive a like pressure, and a similarity will exist between the brooms thus made and greatly enhance their marketable values.

At one end of the ridges containing the grooves? 11 e are recesses 9, extending inwardly a short distance by the side of the grooves, and on their opposite ends are similar recesses, h, but on the opposite side of the groove. The object of these recesses is to permit the ends of the tie-wires to pass through and clasp on the opposite side of the straw. A somet what larger recess, t, is formed in the side of the die, at the end of each groove d e, to permit the bending-fingers of the rocker-shaft to enter.

j j represent guard-arms,which are secured to the sides of the lower die, near the rear end, and project upwardly a short distance above the face of the die.

It k are similar guard-arms, secured to the sides of the lower die midway between the forward and rear ends. The upper die, L, has only thetwo downwardly-prey"ectingarms Z Z, located near the rear end, so that when the two dies are clamped together they pass down i on opposite sides of the lower die next to the rear guard-arms, j j, as shown in Fig. 10. The forward end of the die on one side of the handle-rest f has a shield, m, which extends back to the 'crossgroove d. This shield is the same height as the guard-arms j 7c. The upper die, L, is also similarly provided with this shield m. It will thus be observed that when the two dicsare clamped together the sides are wholly inclosed, so that no part of the broom-brush is exposed except the protrn ding end and the spaces between the guardarms j k Z and shields m.

n represents one of the tie-wires, which is simply a straight piece of suitable wire. This is laid in the groove (1 next to the handle. The tie-wire 0 which rests in the rear groove, 6, is somewhat longer than the wire a, and has hooked or upturned ends 1;. The object of this is to prevent the straw in the broom from being crowded together after the wire is bent and pressed into position.

The operation is as follows. The machine as shown in Fig. 1 is in position to receive the broom. The straw is first bound to the handle in the ordinary manner. It is then ready to be placed in the machine. The tiewires 1 0 are first laid in their respective recess or ledge f. The lever J is now brought into requisition and drawn forward, causing the plunger D to descend, tightly compressing the broom between the die-heads,as shown in Fig. 10. The toggle-jointed levers G H hold the dies in this position.

As shown in Fig. 2, the stationary diverg ing fingers on the rocker-shaft are in position to approach the protruding ends of the tiewires on 0. To bend them into the position shown in Fig. 10, the lever X is drawn forward, which moves the carriage M toward the die. The diverging fingers R therefore strike the ends of the tie-wires and cross them, after which the carriages M are caused to recede from a the dies, and the latch Tdrawn forward to dis engage the end T from thehead S. The shaftO is then rotated, so that the hinged fingers Q Q appear in the position formerly occupied by the stationary fingers R. The lever X" is again drawn forward, which moves the carriages M up to the dies, and as the fingers Q Q strike the partially-bent ends of the tie-wires a 0 they are forced back through the recesses g h on opposite sides of the straw. then raised, which drives in the plunger P and causes the outer ends of the hinged fin gers Q Q to move toward each other and tightly clamp the ends of the wires between them. 4

What I claim as new, and desire to secure by Letters Patent, is as follows:
