GIN-SAW GUMMER AND DIE THEREFOR.

SPECIFICATION forming part of Letters Patent No. 374,692, dated December 13, 1887.

Application filed June 18, 1887.

.To all whom it may concern:

Be it known that I, TURNER HUNT NANoE, a citizen of the United States, residing at Talladega, in they county of Talladega and State of Alabama, have invented a new and useful Imthe same attached to a gin-saw. Fig. 2 is a top plan view of the same. Fig. 3 is a yertical longitudinal sectionalrview taken on the line a: x of Fig. 2. Fig. 4c is a transverse sectional view of the same, taken on the line y y of Fig. 2. Figs. 5, 6, 7, 8, and 9 are detail views showing various forms of the die and punch.v

AB represent a pair of metallic bars, which are arranged side by side and constitute the body of the gin-saw gummer and pointer. The inner ends of the said bars are provided with forward-extending ears C. On the inner side of the bar A, near the iront end thereof, is made a longitudinal recess, D, in which is located a revoluble die, E, which is provided with a series of radial openings, F, as shown. This die is secured on the inner end of a screw, G,and by means ot the said screw the die may be clamped rigidly to the bar in any desiredposition. H represents a bolt, which extends transversely through the bars A B at a suitable distance from their inner ends, and serves to clamp the said bars together. The head of this bolt projects outward beyond the bar B, and is enlarged, as shown, andthe shank of the bolt projects beyond the bar A and passes through a slotted opening made in the lower portion of the vertical arm of a rectangular guide, I. This guide is supported at any desired vertical adjustment by means of a clamping-nut, K, which is screwed `onto the threaded extremity of the bolt.

L represents an operating-arm, which is arranged on' the upper side of the bar B, and is secured thereto near its outer endnby a piv- Serial No. 241,766. (No model.)

otal bolt, M. The inner end of the said operating-arm is provided with an enlarged head, N, in the frontside of which is a vertical lateral recess, O. p

P represents a clamping-plate, which is secured to the inner side of the head N by means of a set-screw, It.- The said clamping-plate is provided at its front end on its inner side with a vertical groove, S, that communicates with no the recess in the head.

T represents a punch, which is fitted in the said groove and is arranged inthe recess in the head, and is secured inposition therein by turning the screw R, s0 as to clamp the 65 plate P against the punch. A ilat spring, U, is secured to the arm L by a setscrew, andthe free end of the said spring bears against the inner side of the guide I, and thereby serves to normally move the free end of the rod L 7o laterally from the die, so as to carry the punch from the same.

It will be observed by reference to Fig. 2 that an opening is left between the opposing front sides o f the ends of the bars Aand B suf- 7 5 cient in width to admit the insertion of one side of the gin-saw.

V represents an operating-lever, which is provided Aatits outer end with a handle, W. n At the inner end of the said lever is formed 8o an eccentric cam, X, which Ais arranged upon the head of the bolt H, and is pivoted thereon by means of a bolt, Y. This cam is adapted to engage the operatingarm L when the lever is moved inward, to cause the said arm to move the punch toward the die and across the edge of the saw.

Z represents a pair of arms, which have their inner ends pivoted to the outer sides of 'the Vears C. The said arms extend forward and 9o have their outer ends curved upward,as shown,

the said -upturned ends of the arms being pro`- vided with a series of openings, A.

B represents a weight, which is provided on its under side with an extended arm, C'. 95 The said arm is arranged between the upturned ends ot' the arm Z, and is'pivoted thereto by means of a bolt, D', which may be inserted through either of the series of openings A. In the lower side of the arm is made a vertical 10o slot, E', which is adapted to receive the outer edge of the ginsaw, and thereby the said arm constitutes a guide. By reason of the series of openings A the weight and theguide may be adj usted vertically on the arm Z, and thus adapt the device to be used upon gin-saws of different sizes.

F' represents a gage-arm, which is pivoted to the inner side of one of the arms Z, near the inner end thereof, by means of a set-screw, G'.

This setscrew enables the gage-arm to be turned to any desired position and secured therein. At the rear end of the gage-arm is formed a transverse downwardly -extending gage-tooth, H', which is adapted to successively engage the teeth ofthe gin saw while the machine is being operated.

To the outer side of the bar A, ata suitable distance from the outer end thereof, is pivoted a bell-crank lever, l'.

K' represents a feedingarm, which has one end pivoted to the short arm of the bell-crank lever, and the free end of the said feeding-arm is provided withatransverse tooth, L',ad`apted to engage the ginsaw teeth successively.

'M' represents an arrn,which has its rear enjd secured to the under side of the bar A. The lower front end of the said arm is provided with a longitudinal slot,.O', adapted to receive one side ofthe gin-saw. A handle, P', -is provided at its upper end with a threaded stu'd, which passes through an opening in the rear end of the arm M' and enters the threaded opening in the bar A, and thereby serves to secure the handle and the arm M' rigidly in position under the said bar A.

R' represents a pulley, which is arranged on v the under side of the rear end ofthe bar A and I vis journaled on a vertical bolt, as shown. A i

chain, S', of suitable length passes 'over the said pulley, and has one end attached tothe lever V and the other end attached t'o the belly crank lever l'.

T'representsa coiled retractile spring which connects the be1l-crank lever to the guide I,

the said bell-crank lever forward.

U' represents a stop which projects from,Y one side of the operating-arm L and 'extends y toward the operating -lever V. A chain, V', i of suitable length connects the operating-lever V and the operatingarm L, and serves v'to limit the outward movement of theoperatng-le'ver.

The operation of myinvention is as follows: The arms Z are arranged on the upperside of t the gin-saw a and rest upon the usualblocks, I b, which separate the said sawv from its com The rear side of the 'saw enters the space between the die andthe opposing side panions.

of the bar B, and the front edge of the saw enters the'slot in the guidearm C'. rlhe gagearm F is then caused to engage one of the the gin saw, and the arm M' is arranged to receive the rear edge of the saw,the front ends of the said arrn bearing against the rear sides of the block b. The punch is then adjusted between the clamp-plate O and the enlarged head of the operating-arm L. The operator then grasps the handle P' with his .left hand and grasps the handle W with his right hand and moves the lever V inward, so as to cause the carn at the rear end of the said lever to bear against the outer side ot' the arm L, so as to force the punch across the edge of the saw and thereby cut out the space between two of the teeth thereof` to the required depth. In Fig. l of the drawings, c indicates the sawteeth before being operated upon by the saw set and gu-mmer, and d indicates the teeth that have been Voperated upon by the same. It will be observed that the V-shaped faces between the saw-teeth do not converge to a sharp point at their inner ends, but are truncated. This is caused by giving a similar shape to the openings in the dies and to the points of the punch. When the lever V is moved outward after each movementof the punch, the chain draws rearward on the bell-crank lever I' against the tension of the spring which counects the said lever to the guide Land thereby causes the said bell-crank lever to draw rearward upon the feeding-arm K', which feeding arm, being engaged with one of the sawteeth, rotates the saw a distance corresponding to the length of one tooth, and thereby presents another tooth to the action of the punch.

In Figs. 5 to 9 I illustrate various forms of the punch and die, which are adapted to be employed in connection with my improved saw gumming and pointing device,

Having thus described my invention, I claim- 1. In a gin saw pointer and gummer, the combination of the main body of the machine, having the arm M' on its under side, adapted to bear against the blocks between the ginsaws, and the arms Z, pivoted to the front end of the main body or portion, and having the weight B' at their outer ends provided with the 'downward-extending slotted arm C', to balance the machineon the saw, thesaid arms being adapted to rest upon the upper sides of the blocks between the saws, substantially as described.
