' b all whomit may concern.- i

Be it known that I, VERNON Hoxrn, a citizen of the United States, and a resident of Adrian, in the county of Lenawee and State of Michigan, have invented a certain new and useful Staple Forming and Discharging Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, su'ch'as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of" this specification.

My invention relates to wire-working machinery, and particularly to mechanism for use in wire fence making machines or the like-for successively severing sections from a wire intermittently fed thereto, forming staples therefrom, discharging such staples from such mechanism and clamping them about registering intersecting portions of a fabric being woven. The invention is not restricted to use insuch connection as it may be used in any connection forwhieh it may be adapted or ap propriate.

The object of my inventionis the provision of an improved and highly efficient mechanism of this class, which is simple in its operation and construction, composed of a minimum number of parts, and is particularly adapted for'use in narrow spaces whereby a number of the same can be placed side by side and used in machines for manufacturing fine meshed fabric, such, for instance, as chicken fabric or the'like.

The operation, construction and arrangement of the parts of the invention are fully described in the following specification, and while in its broader aspect it is susceptible of numerous modifications, a preferred embodiment of the same is illustrated in the accompanying drawings, in which,-

Figure 1 is'a side elevation of the'invention, with a portion broken away and the movable parts at their limit of forward movements. 2 is an opposite side elevation thereof, with a portion broken away and thedischarging plunger at the limit of its rearward movement relative to the male staple forming part. Fig. 3 is an enlarged front elevation of the upper portion of the same looking in the direction of, the arrow in Fig. 2. I ig.v 4 is a side elevation of the mlevice similar to that of Fig. 2, with the mpvable parts in full retracted position. Fig. 5 is an enlarged top plan view of the forward portion of Fig. 4:. Fig. 6 is an enlarged inner sideview of the upper staple forming and guiding part, with associated similar to Fig.6 showing successive stages of the staple forming operation in dotted lines, and Fig. 8 is a similar view with different parts in section and theplunger in the'aet of ejecting'a staple from the device.

Referring to the drawings, 1' designates what maybe termed the holder of my in vention, which is suitably secured in proper position 1n the machine in' which it is to be used, as is well understood in the art. 'The inclined, as indicated, and vertically grooved or recessed from its rear end forwardly, as at 2, Figs. 1,6 and 7,'to receive the plunger 3. The recess andplunger 3 are shown as being provided in their sides near their upper edges with complemental grooves t and is provided atits forward end with a stapledischarge nose 6,'wh1ch 1s adapted to work tension 7 in the forward end of the holder. Mounted on one side of the holder 1 is a recipro-catory plate or member 8, which is held to the holder and guided for reciprocatory movements relative thereto due to the lower portion of such plate being broadened and flanged to slidingly interlock with a complement-a1 portion of the holder, as shown at 9. upper portion projecting above the top of the holder and provided at its forward end with a tongue which project's laterally therefrom in a downwardly extemling curve, with its free end .tern'linafing immediately over the plane of movement of the discharge nose (3 when at its limit of forward movement. The planes ofmovementof the plun gel-.3 and plate 8 slightly diverge from the forward end of the holder rearwardly to cause the end of the tongue to gradually lower into the path of movement of the purpose of forcing a staple back in the discharge-way after entering the same.

The tongue 10 which forms both the male staple formingmember and the staple-slide of my invention, when moved rearwardly Patented Feb. '7, i911;

portions of the holder. Fig. 7- is a view' ribs 5 to guide the reciprocatory movements of the plunger m the holder, and the plunger into a staple-discharge way or shallow ex-' upper surface of this holder is preferably The plate or member 8 has its plunger-nose on its rearward stroke for the rig from 'its'for'wa rd position, cooperates 'with a lower block or subjacent portion .11 of the holder and-with the overhanging part 12 of a block or portion 13 of the holder to form into a staple aseetion of wire previously fed thereto and severed as hereinafter described. The block'or portion 11 is disposed on the top of the holder 1 at the side of the staple discharge-way 7 which is contiguous to the plate 8 and is immediately at the rear of an incut 14 in the contiguous side of the holder, through which incut the staple wire a feeds. The forward endor nose of the block or portion 11' is tapered fronrits outer side edge inwardly to the edge of the dischargeway 7, as indicated at '11 Fig. 8, to guide the coacting stapleleg thereto on the rearward or staple forming movement of the plate 8.

The portion 13 is shown in the present instance as comprising a block, which is secured to the top of the holder at the side of the discharge-way .7 opposed to the plate-S and has" the part .12 projecting laterally from its inner side'over the discharge-way and in contiguous position with the plate 8.

The under side of the part 12 is curved in substantial parallelism with the tongue 10,

as is also the top of the blockfjll, and suitably spaced from such block to permit the tongue 10 to freely pass therebetween. The

forward portion of the part 12 is undercut or fashioned on the underside, thereof to form a shoulder 15,which faces to the front and has the end thereof adjacent to the plate 8 starting near the front end-of said part, thence continueslaterally and rearwardly in spiral form to immediately above the plane of movement of the plunger, and terminates in the straight surface 16, which continues rearwardly for a distance in contiguous parallel relation to the plane of -movement of the plunger-nose 6, as best shown in Fig. 6. It is thus apparent that on a rearward movement of the tongue 10 ,the undercut surface 17 of the part 12 cooperates therewith and with the surface 1 of the holderimmediate'ly in advance 'ofthe block 11 to form into U-shape a section of .wire drawn therebetween, while the spiral shoulder 15 causes the upper leg of the staple to swing laterally to the horizontal plane of the lower leg during the forming operation and at the same time cooperates with the tapered nose of the block 11 to guide the staple into the discharge-way in advance of the plunger-nose 6.

18 designates an oscillatory wire-cutting knife, which is mounted in an: ineut in the side of the holder 1 at the forward end I thereof and in the path of movement of the lower forwartl portion of the plate 8, see Figs. 2 andi l. This knife is pivoted to the holder as at 19, and has an upper nose portion 20 provided with a vertical aperture the upper edge of 21 thercthrough for guiding the feed of the wire-thread a to the staple-forming parts. Thetop edge of the knife 'is rounded to adapt it to continue in shearing contact 'with the fixed shoulder or cooperating shearing edge 22 of the holder. The oscillatory movements of the knife are limited in either direction by shoulders on the holder, and are actuated by a cam member 23 on the forward end portion of the plate 8 working in a recess and against a cooperating cam surface on thetail-piece 25 of the knife. When the knife is at the limit of its forward, movement the upper end of the aperture 20 therein registers with the' incut 1 1 in the holder side, and when in this positiona length of the wire a is fedto the forming parts, as indicated in Fig. 2, by

any suitable intermittent feeding-mecha- 1 nism, such, for instance, as that shown in my former United States Letters Patent No. 879,965 of Feb. 25, 1908.

Rising from the plunger 3 is a block or part 26, which has a lug 27 projeeting'from one sidethereof and working in a'longitudi- 'nally-extending slot 28in the plate, which slot is shorter than the stroke of the plunger tocause the plate to move with the plunger during portions of its movements and to permit it to remain stationary relative to the plunger during the balance of its move-- ment. I 1

29 designates-an arm, which lies parallel to the plateS at the inner side thereof and has its forward end pivoted, as at 30, to

the forward end of such plate and has its rear end reduced on both its upper and lower edges to-form the beveled shoulders 31 and 32 at the inner. ends of such reduced edges, the upper shoulder 31 being in advance of the lower one, as shown in Figs. 1, 2 aud t. When the plunger is at the limit of its.rear stroke the reduced end of the arm 29 rests on the top of the block or part 26 thereof with its shoulder 32 in abutment with the beveled edge 26 of such part and is held in such position by a finger 33, which rises from one sideof the holder 1 near its rear end and has its upper end angled to adapt it to overhan and coact with the arm 20, showm in Fig. 4. 'On the forward stroke of the plunger the block 26, coacting with the shoulder 32, forces the arm .29 and attached plate 8 back to their forward posi- As the plate 8. reaches its limit of tions. forward movement, the upper reduced edge of the arm 29 moves under the overhanging portion of the finger 33 to permit the rear end of the arm- 29-to raise to release the engaged beveled shoulders 32, 26, which raising is accomplished by the action of said beveled shoulders, 'as is apparent, thus permitting the plunger to continue its forward movement alone to discharge a staple from lBU,

the holder, as is apparent. On the rearward stroke of the plunger the lug 27 is timed to engage with the plate 8 at the rear end of the slot 28 as the block 26 moves under the lower reduced portion of the arm 29, and, on the continued rearward movement of the plunger, the beveled shoulder 31 on the arm 29 coacts with a corresponding beveled surface 33' on the finger 33 to effect a positive lowering of the linger 29 in position for its shoulder 32 to enact with the beveled edge of the block 26.

3 1 designates a plunger actuating table, which is slidingly mounted to the rear of the holder or holders and connected to the plunger-s thereof by links This table maybe actuated in any suitable manner, or

any other means may be employed to actuate the movements of the plungcrs of the associated holders.

The operation oi my invention is as follows:During the relative movements of the plunger 3 and plate 8, or while said plate. is in its forward or stationary position, a predetermined length of the wire a is fed through the aperture in the knife 18 and up through the incut 14 in the holder-to the' rear of the forming tonguelO Fulfill) advance of the female forming parts 12 andi On the initial rearward movement of the plate 8, which is accomplished by the lug 27 moving into contact- With the plate at the rear end of the slot 28 and moving the plate therewith, the knife 18 is oscillated,

due to the coaction of the cam 23 with' the .cam surface of the tail-piece 25 ot' the knife as it recedes from the recess 24 therein, and

a consequentsevering ot the fed section of wire accomplished by the shearing action of the knife and edge 22; of the holderf At approximately the period of severance of the section. of Wire, such section is gripped between the coacting forming surfaces, and on a continued rearward movement of the tongue 10 with the plate 8 is drawn between the surfaces 16 and i7 and formed into i?- shape thereby. During the forming opera tion of tl staple the lower leg thereof is moved into register with the staple dis chargeway 7 due toils coaction with the tapered enc upper log a caused to desc'ibc a quarter turn with the lower leg as its" axis and is guided into the discl 1r ia ge-way in advance of the plunger nose by the action thereon oil', the spiral .houlder 15 and straight portion 16 or the block 14:- During the continued rearward movement the staple held in the discharge- "'ay by said portion 16. it is' thus seen that the tongue 10 both serves as the male forming member and to guide the movements o the staples to discharging positirm. in the forward stroke of the piunger, the staple is lischarged from the who 7 nntl clenched about or to an alining ll." of the block 11., while the object. The plate 8 also returned to its forward position on the forward stroke of the plunger by reason of the coaction of the edge of the block 26 withthe beveled shoulder 32 on the arm 29, which coaction is released as thenpper reduced edge of said arm passes under the angled end of the finger 33, thus permitting the plunger to continue its forward movement alone, due to the-h1g2? working in the slot.- 28.. The forward end of thep'late 8 is notched on its inner edge, as at 36,36, to receive the legs of a staple as it assumes an angle relative to -the discharge-way whenbeing formed and turning to horizontal position.
