MACHINE FOR FEEDING NEEDLE-BLANNKSS.

v SPECIFICATION forming part of Letters Patent No. 281,961, dated July 24, 1883. Application filed February 23, 1882. (No model.)

To all whom it may concern.-

I Be it known that I, JOHN BERRY, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Needle-Blank-Feeding Machincry for Compressing-Machines, of which the following is a specification.

This invention relates to improvements in the construction of devices for feeding wire needle-blanks to compressingmachines, the object being to simplify the usually complicated machinery of this class, and to render said devices more positive and sure in their operation.

In the drawings forming part of this specification, Figure 1 illustrates said needle-feeding devices constructed according to my invention. Fig. 2 is a perspective view of the front side and end, and Fig. 4 a like view of the rear side and front end, of the machine. Fig. 3 is a view of ablank-guide removed from the parts shown in Fig. 2. Fig. 5 is a rear elevation. Fig. 6 is a transverse section 011 the line 2 2, Fig. 5.

In the drawings, A indicates a portion of the compressing-machine, to which the feeding devices are attached. A is the bed. B is a bracket on bed A. (Z is a needle-clamp slide. is an adjusting-screw in block 1 b is a stopscrew. e is a connecting-rod. e is a lever. a a are needle-blank holders. a is an inclined blank-guide. 12* is an end guide for the blanks. i is an arm on slide d. i is a slide-stop. n is a retracting-spring. 'w is a b1ank-pushe1x o is a hand-hook on pusher w. c is a cord; 0, a cord-pulley. c is a weight. w m indicate blanks. x and 0c are blank-clamps. w is a clamp-spring. o is a pivoted blank-abutment. o is an abutment-spring. o is ablank guideblock.

Like letters refer to like parts in the several figures.

The blank-feeding devices herein shown and described are adapted to be employed with the needle-compressing mechanism and with the blank-carrying chuck and its operating devices which are shown in my Patent No.

cl is a connection-block on slide d. 6.

249,822, dated November 22, 1881, or with othersimilar machinery for doing the work therein described.

The bed A of the feeding device is provided with a bracket, B, standing at right angles to the side of said bed, and by which said device is secured in a proper position on the ma chine, a portion of which is represented by A. Theupper surface of the bed A is grooved longitudinally, and the slide (Z is provided on its underside with a ClOX'GtELlLShZtpGd tongue to fit said groove, and is adapted to slide and thereby be guided on said bed. Said slide (1 has a block, d, on its under side, through which an adj usting-screw, 6, passes, and is secured thereto by proper nuts, as shown. Said screw 0 carries on one end a pivot-block, to which one end of a connecting rod, 6-, is pivoted, and the opposite end of said rod is pivoted to the. end of a lever, c", which is caused .to have a vibratory motion through any suitable connection with the compressing machine, and whereby the slide (1 is given a reciprocating motion on bed A.

In practice a cam or other similar device is employed for actuating lever c by which a positive movement of the end of said lever from the part A of the machine is imparted thereto, and a like positive motion in the same direction is thereby given to the slide (1. The return movement of said slide is effected by the retracting-spring n, which is secured to an arm, 1', on said slide and to the bed of the de-. vice. A stop-screw, I), is provided in block d, whereby the degree of the movement of said slide by said spring is regulated.

The forward end of the slide (1 is provided with needle-blank grasping or clamping de vices, as follows: A sliding clamp, 00*, is fitted in a short longitudinal groove at the end of slide d, and is forced inward by a spring, 00*, which bears against its end toward a clamp plate, 00 011 said slide (Z. A block, 3, stands upon the surface of said clamp :6 A pivoted needle-abutment, o, is located on slide d, so that its free end will be opposite the meeting line of the clamps 0c and 00 and a flat spring, 12 bears against the outer edge of said abutment. A guide-block, o, is located on the.

edge of slide (1, near its front end, and is provided with an offset 011 its upper side, the vertical side of which is on a line with said meeting edges of the clamps Two needle-blank holders, (0 a, are secured upon the rear edge of the bed A, the latter over the former, and holder a is so formed as cut away to leave a passage from the end of said chamber between said holders to the upper face of the slide (1.

A blank-guide, o", is secured adj ustably to the end of the holder a, and its free end eX- tends in front of the ends of the blanks a: x, as

. shown in the several figures.

A hook, 0, is placed on the pusher w, 'by which the operator can draw the latter back away from the blanks when it becomes necessary, and a slide-stop, i is pivoted on the rear dropped back of the arm 2' 011 slide (2, and retain it against the action of spring at in a rearward position, if need be.

The operation of my improvements, in conjunction with the aforesaid compressing mechanism and chuck devices, is as follows: The blank-pusher w is drawn back, and a suitable number of blanks 00 w is placed in the chamber between the holders a a in the position shown, the said pusher being then released and allowed by the action of weight a to crowd against the line of blanks, forcing the forward one of the series to be carried against the upper face of the slide d, guided downward by the inclined side of the guide-block a. The slide (Z now moves back by the action of lever c and carries the meeting edges of the clamps at about under the said foremost needle-blank,

and as said slide arrives about to this point in its movement the end of block 8 on the clamp 00 is carried against the block (4 causing the last-named clamp to come to a stop, while clamp moves from it and leaves an opening betwc en the edges of said two clamps, into which said foremost needle -blank is forced. The slide (Z now moves forward, carrying block 8 away from block a", and spring 00* acts to force clamp 00 against the blank, and the latter is thus tightly grasped between said clamps, and is carried out to the position shown in Figs. 2 and 4, with its rear end against the edge of the pivoted abutment o. The aforesaid chuck now advances and seizes the projecting end. of said separated blank, and if the latter be a little too long the said abutment is forced against the spring 0, and no injury results to the blank side or edge of the holder a which may be or to the mechanism, and as the blank is drawn out of said clamps said abutment swings back to its former position. The end guide, 1), serves to force any blanks which may project beyond a proper line as they move forward'back into said chamber between the holders a a Thus, as above described, this feed device holds the blanks between stationary holders having a chamber between them for receiving said series of blanks side by side in a line, and embodies means for sliding said series bodily and causing the foremost of said blanks to be deposited between clamps on a movable slide or blank-sepa rator, which carries the blank to a position directly before the open end of a chuck, which seizes it, draws it from between said clamps, and, immediately that the slide (1 moves back to seize another blank, moves forward, revolving meanwhile, andholds the free end of said blank between the dies of the compressing-machine,

which reduce it to proper size, all substan tially as described relative to the action of said chuck and compressing mechanism iii my said patent, to which reference may be had.

It will be seen that the disposition of the holders (0 a and the inclined block a is such that they unitedly form a blank-chamber hav ing-a curved end, whereby the forward end of the line of blanks is guided downward against the face of the slide (1. It is obvious, however, that the holders a a may be set vertically, or nearly so, and deliver the blanks in a straight line to said slide, thus obviating the necessity of curving the end of said chamber.

The stop-screw 1) provides for arresting the forward movement of slide (2 at such a point as will bring the end of the blank held by the clamps a and as directly before the end of said chuck, so that the latter can properly seize it.

The adjusting connecting-screw 6 provides for determining the stopping-point of said slide in its rearward movement so exactly as to bring the opening between the clamps x so" directly under the foremost blank, which is carried against the slide (1, so that said blank will unfailingly enter therebetween.

Vhat I claim as my invention is 1. In needle-blank-feeding mechanism for compressing-machines, the stationary blankholders an, having a blank-chamber between them, ablank-pusher to slide in said chamber, and mechanism, substantially as described, for grasping and moving sidcwise from said chamber one needle-blank at a time, combined and operating substantially as set forth.

2. In combination, the stationary blankholders a a having a blank-chamber between them, a blank-pusher to slide in said chamber, the slide d, adapted to have a reciprocating motion under the end of said blankchamber, and mechanism, substantially as described, located on said slide for seizing the needle-blanks on one at a time, substantially as set forth.

3. In combination, the stationary blankholders (4 (6, the pusher w, the slide (1, provided with the clamp -plate 00 the clamp 00 provided with the-block s, and the spring 00, substantially as set forth.

4. The slide d, having the abutment '0, piv- 5 oted thereto, and the spring '12", to bear against said abutment, all combined and operating substantially as set forth.
