MACHINE F OR CUTTING AND STAMPING NEEDLES.

SPECIFICATION forming part of Letters Patent No. 268,875, dated December 12, 1882,

Application filed March 24, 1882:. (X model.)

To all whom it may concern Beit known that I, WILLIAM H. DAYTON,

'of Torrington, in the county of Litchtield and State of Connecticut, have invented an improvementin Machines forOuttingand btam ping Needles, of which the following is a specification.

' Needles have been made by what is known as the cold-swaging process, in which steel wire of the sizeot' the needle-shank is reduced down and extended to form theneedle portion: In this operation the piecesof wire from which the necdlehla-nks are made may vary in thickness and the needle portion reduced by swag- 1 ing from the wire may be longer in one instance than in another. Hence I provide for cutting oft all the needle-blanks to the same length.

My present invention is for cutting off the point of the needle-blank and therebymaking the needle the proper length to be grooved,

and the eye punched and the point ground.

My presentinvention relates to the mechanism for cutting off the needle-blank to the properlength and for stamping upon the shank the numbers, names, or other marks by which the needle is to be known in the market.

In the drawings, Figure 1 is aside elevation of the needle-stamping machine with part of the fly-wheel removed. Fig. 2 is a plan of 0 the same. Fig. 3 is an end view sectionally at the line a: m, Fig. 2. Fig. 4 is a separate plan View of the cutting device. Fig. 5 is a separate view of the stamping mechanism; and Fig. 6 is a detached view in large size of the die-holder and stamping-slide.

The driving-wheelAis upon a shaft, 0., that is supported in the vertical frame B upon legs C. At. one end of this shaft a is a disk and crank-pin, a, that operates the cutting and 7 4o stamping devices hereinafter named; and near the fly-wheel A there is a bevel-gear, b, that gives motion to the bevel-gear b and vertical shaft b and by the gearing and horizontal shaft b the end gear wheels, b b ,are revolved. 5 The gear-wheel b is on one end of the feedingscrewc, and c is a twin screw, that is geared to the screw 0 by the three gear-wheels at 0?. These screws 0 and c are supported at one end by the arm 0 that extends out from the frame B, and at the other end by studs that extend into the recessed ends of the screws, as shown by dotted lines in Fig. 2, such studs being on the back of the die-holder d. i The screws 0 c are adapted to receive into their threads the needle-blanks i, (these are shown in position in Fig. 4,) the shanks of the needles resting upon the screw 0 and the needle portions on the screw 0, and these screws are revolved in the same direction as indicated by the arrows, and they move the needle-blanks along gratiually to the die-holder d. and by their direction of revolution thev press the ends of the shanks against the guide-fence e.

There is a yielding bar, e, held by springarms that project out from the fence 0. The needle-blanks are carried under this bar 6 at the time they are being cut off to length. This bar prevents the needles jumping out of the screw-threads as they are sheared ott'. The bed-shear h and moving-shear it perform the cutting, and the grooves in the screw c ,near the shear are made wider, so that the needleblank may not be bent by the pressure of the screw tending to move the same at the moment that the blank is arrested by being cut oif by the shears.

There is a double-inclined gage or fence, f, upon the surface of the fence c,and thispresses the needle blank toward the cutters, and the parts are placed and timed so that the shear I6 descends and cuts oii' the blank just as the heel of the shank reaches the apex of the double incline f, as indicatedin Fig. 4. The screws by their revolution carry the needle-blanks on and they move back from the cutters as their shanks pass along the rear sideof theinclined fencef, and each needle-blank is delivered in succession upon the inclined upper surface of the die-holder d to be stamped, as hereinafter indicated.

The shear k is upon a lever, provided to the stock Id, and a pin, 1, upon the stampingslide 1, that receives motion from the crank-pin a. and link a, operates upon the lever and shear to cut off the blank at the proper time, and the spring k opens the shear. The bedshear his upon a stock, It, and this and the stock 10 are upon a slide-rest, If, that is provided with adjusting-screw 3 and clamp-screw 4, so that the parts can be moved to adapt the machine to different lengths of needles and clamped firmly in place when adjusted.

The stamping-slide l is between the frame B and the stationary plate in, that receives support from the head-block it upon the frame B. The rest-block l behind the slide lis sustained by the bolt a passing lromitthrough the headblock a; and there is an intermediate regulating-block, n that is adjusted by the screws 6 6, that pass through the head-block a. By this means the rest-block I will be firmly held, but can be adjusted with the greatestaccuracy, and with it the stamping-slide lwill be adjusted; but it is free to be moved up and down by the link a and crank pin. There are cheekpieces 19. having flanges that pass into the groove 7, in the side of the stamping-slide to guide the same in its vertical movement.

It is preferable to employ a face-plate of hardened steel upon the surface of the stamping-slide, as at 0, and this is provided with an arm that carries the feeding-incline .9, upon which is a movable gage, s. The surface of this plate 0 has a ridge across it in line with the lower end of the feeding-incline s, as seen in Fig. 6.

The die-holder d is bolted by the plate d to the frame. Its upper surface is inclined, as aforesaid. There is a recess formed. for the reception of the engraved stamp or die 1*, such die having the letters, marks, or number to be pressed upon the needle-shank. This die is held by a clamp and screw, as shown in Fig. 5. The face of the die-holder is vertical and parallel with the steel face-plate 0.

The parts are timed so that when a needleblank is delivered flOllJ the screws and rolls down the inclined upper surface of the dieholder (1 the stamping-slide l and the feedingslide 8 are at their highest point, and the needle-blank is checked by the apex of the feeding-incline s and the ridge across the-surface of the plate 0, and its correct position endwise is insured by the gage s. The consequence is that as the slide 1 commences to move downwardly the shank of the needle-blank is rolled in between the vertical faces of the die-holder d and plate 0, and rolled down over the face of cl and in contact with the stamp or die 7', and from that it receives the marks and numbers,

.and it is rolled on below the lower end of the die-holder d and drops into a suitable receptacle, ready for. the subsequent operation of grooving, punching, 850. The stamping-slide rises, and the operations are repeated.

There should be a cover for the gears that drive the screws 0 c, to prevent accident to the attendant, who is simply required to supply the needle-blanks upon the screws 0 0, so as to keep the grooves tilled, and as these screws 0 c revolve once for every revolution of the shaft a there will be one needle-blank delivered each reciprocation of the stamping-slide.

I claim as my iuvention- 1. The combination, with the screws 0 c for! feeding the needle-blanks and mechanism for actuating the same, of the shears hk and means for giving motion thereto, substantially as set forth.

2. The combination, with the screws 0 0, of

the fence 0, bar 0, shears h k, and actuating mechanism, substantially as set forth.

3. The combination, with the screws 0 c, of the fence 6, inclinef, and shears h k, and actuating mechanism, substantially as set forth.

4. The die-holder d, having an inclined upper surface, the die or stamp, and the reciprocating stamping-slide, and means for supporting and moving the respective parts, substantially as set forth.

5. The reciprocating stamping-slide Z and means for supporting and moving the same, in combination with the die-holder d, die or stamp, feeding-screws, and cutting mechanism, substantially as set forth.

6. The feeding-incline s and gage, in combination with the stam ping-slide, the die-holder,- the die or stamp, and mechanism for supporting and moving the respective parts, substantially as specified.

7. The combination, with the feeding-screws and fence, of the shears h 70, and mechanism for supporting and adjusting such shears so as to vary thelength of the needle-blank,substantially as set forth.

Signed by me this 14th day of March, A. D. 1882.

WILLIAM H. DAYTON.
