,' Anotlnir object of the invention is to pro-,

vide a novel and improved machine of this general character wherein stock is fed ito the machine and cut oil?' into lengths togetdier with. means for successively forming sa-id lengths into staples and driving the same into the work.

Another object of the invention is to. pro-. vide a novel andimproved machine (if this general character driven in any preferred manner and wherein the various operations incident to forming the staple and driving single strand of material or,

reference being had to'the acis an obthe same into the work are accomplished in The invention consists in the details of constmction and in theicombinution and arrangement of the several parts of my improved. stapling machine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and rdvantzn gems for use, as will he hereinafter more fully set forth. i

The novel features vof my inventi pn will hereinafter be definitely claimed.

F i are 12 is a sectional view takcnsubstantially on the line 12l2 of F igurc 11.

As disclosed in the accompanying draw; ings, my improved device comprises a head consisting of two sections A and B arranged side by side and having at the lower ends thereof a bottom plate G suitably secured thereto and providing the means for main taining said sections A and B in assembled relation. The bottom plat Ceatcnds in advance of the forward ends of the sections A and B to provide for the mounting of a front end plate D bolted or. otherwise secured in applied position and further maintaining the sections A and B in assembled relation.

The sectionsA and B at their tops are continned by the upstanding members 1 in close contact one with the other and providing the post having a hearing 2 for an end portion of a shaft 3. This post is laterally continued rectangular bracket 4 connected with the rear faces of the scc+ tions A- and B and provided with a second or outer bearing 5 for the shaft 3. The bracket 4 at a point intermediate ings 2 and 5 is provided with a third hearing 6 thehore of which is at right angles to the applicdishaft 3. Rotatably disposed through partly in elevation of the medium of a shaft Li with a suitable rupportii hraricet i. \v'hde in the aeeonrdrawings .i show but two arms 10 understood that it preof such arms panning}; and 12 it is to he ferred one or a greater nuniher may he used.

j n this commotion, it is to he stated that in the in: r 40 is shown with the section B of the head in which the groove 39 is i'iorinec i removed.

iihe'n it is desired to maintain the plate 23 inactive a siiding; hoit may he dtii'diii i to extend arr "he groove 39 nith the he r-r portion ot the ierer 410 within sueh groove. When ihe ierer it) is holddn this li'i'dlli'it'd, the

' with a vertically disposed cutting blade which is adapted upon proper depression of the member 49 to cut the stock S along a line angular to its axis whereby the staple when formed has each of its entering edges pointed. The member 49 extends above the head a desired distance and is constantly urged in such upward or outward direction by the cxpansible spring 51, herein disclosed as encircling the member andv interposed between the enlarged upper end 52 thereof and the top face of the head. The spring 51 maintains the upper or outer end of the member 49 constantly in contact with the periphery of the disc 44, said periphery being provided with a radial cam 53 which operates to force the member 49 downward y to effect a cutting of the stock in proper timed sequence with respect. to the feed of such stock. The initial length 54 of the severed stocl'c drops upon the plate 23 in ad vance of the block 24. and as said plate '23 is retracted said length is received upon the bottom wall of the groove or channel 22,

said bottom wall constituting the applied bottom plate C. When the plate 23 advances with the next succeeding severed length 54 it pushes the first length 54 for ward and across the elongated and transvcrselydisposcd opening 55 provided in the forward or extended portion of the plate G. This operation is continued as the stock S is fed into the machine: p

The applied end plate D together with the opposed face of the head is provided with a vertically disposed opening 56 in which is mounted for reciprocatory movement the elongated hammer 57. The upper portion 57" of the hammer 57 is bifurcated to provide spaced parallel arms between' which is disposed the lower end portionof a connecting rod or pitman 58.' The pitman 58 has projecting beyond each side thereof a pin 5.) which extends within a slot (30 produced in each of the arms of the bifurcation whereby the connecting rod or pitman 58 has a limited movement independently of the hammer 57. The outer end portion of the rod or pitman 58 is opcratively engaged, as at 61, with a disc 62, fixed to rotate with the shaft 3. Upon rotation of the disc 2 the hammer 5 7 is-reciprocated and in order that the rod or pitman 58 may have its requisite oscilthe parts carried thereby.

latory movement the upper portion opening 56 is enlarged or flared. The lower portion of the opening 56 is enlarged, at56, to. have said lower portion of a length substantially coextensive in length with the opening 55 inthe base plate C. 4 i

of the When a length 54 is moved to overlie the opening 55 and the hammer member 57 has been retracted or raised above the ad- 1aeent or forward end of the groove or channel 22, the cam 45 is so timed to permit a severed length 54 to be forced across the opening 55. v I

As the hammer member 57 continues its upward movement a hook member 63 carried by the'lower end portion of the hammer member 57 swings downwardly and along the portion of the length 54 overlying the openmg 55 resulting in such'length being pulled upwardly by the hammer member 57 resultingin the end portions of said:

length 54 extending beyond opposite sides of the opening 55 to be flexed or turned downwardly to provide the completed staple 64 as particularly illustrated in Figure 2 of the drawings. -As the hammer 57 moves downwardly, 'the dog 63 swings upwardly into an inoperative position before the member 57 reaches the end of itsldownward stroke, whereby the member 57 is permitted to force the staple 64 into the work, diagrammatically indicated by broken lines at TV in Figure 1, said work being; suitably rested on a support X.

The hook member 63, as herein disclosed, is substantially L-shaped in form and the lower portion of the member 57 immediately below the pivotal connection 65 for the hook member 63 is cut away, as attlG, to substantially snuglyreceive the stem or leg of the member (iii-as is illustrated in Figure 5. The foot of the hook member is adapted to underlie the lower end of'the member 57 but slightly spaced therefrom as is also 1llus trated in Figure 5.

The stem or leg of the hook member 63 is provided at a predeierinined,point therealong with the forwardly directed pin or lug 67 which rides within a properly formed cam groove 68' providedby the inner face of the end head'p'late D whereby the red uisite swinging movement of the member 63 effected in proper sequence when the hammer 57 is in operation.

The sliding connection between the pitman or rod 58 and the hal'nmer-member 57 causes the hammer member 57 to intermitteutly remain inactive at the proper time to permit a severed length 54 to be properly POSIilO'i'lDfl with respect to the-opening 55 or in other words to permit the member 57- to remain iiiactivc to compensate for the requisite functioning of the plate 23 and I 20 cured to the and walls 0 3 such pocket.
