JOSE]? GBANZ, 0F PLAUEN, GERMANY.
DEVICE FOR FORMING SHUTTLES.
Application filed July 8, 1915, Serial No. 38,696.
To all whom it may concern:
Be it known that I, Josnr GRANZ, engineer, a subject of the German Emperor, residing at Plauen, Vogtland, in the Kingdom of Saxony and Empire of Germany, have invented certain new and useful Improvements in Devices for Forming Shuttles, of which the following is a specification.
This invention relates to shuttles and means of producing the same.-
The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is a vertical section of a shell for constructing a shuttle in accordance with my invention.
Fig. 2 is a side view thereof.
Fig. 3 is a vertical section showing the parts in position ready for the first step.
Fig. 4 is a substantially central vertical section showing the parts in the position they assume when the process is completed.
Fig. 5 is a view showing the parts partially removed.
Fig. 6 is a top plan of Fig. 5 with the punch holder removed.
Like letters of reference indicate like parts throughout the several views.
The shell shown in Figs. 1 and 2 has the general form of a well-known shuttle for embroidery machines. By the means and process soon to be described I produce a swelling in one of the sides of the shell and for this purpose I employ a swage a having therein a cavity of the shape of the swell which it is desired to give to the shell. In this swage, in the cavity in the upper face thereof, is a counterplate c in the lower portion of the vertical face thereof adjacent said cavity, there being a curved recess conforming to the upper portion of the cavity. This counterplate may be secured to the swage a in any suitable manner, as by bolts (Z 6, the flanged heads of which engage upon opposite sides of the counterplate and hold it firmly in position.
i is a punch or wedge-shaped member car- Specification of Letters Patent.

ried in a punch holder f, which latter may be forced downward in any suitable manner. The punch or wedge-shaped member 2' is adapted to slide vertically within a box 9 h and in order to limit the movement of the punch in the box there are fixed in the two sides of the box perpendicular notches m with which engage pins 70 in the punch.
At the lower end of the box there is fixed a top swage n retained in position by the pins 0 in the side of the box, said pins being received in holes in the adjacent face of the top swage, which latter is of the shape of the swelling to be formed in the shell 00. The construction is such that the swage 0?. cannot become separated from the box.
The operation is as follows :The top swage n is placed in the position seen in Fig. 3 and then the shell m is slipped over the front end of the parts 9 h and n and the punch holder f with its punch or wedgeshaped member 71 forced downward until the shell w is forced completely into the depression in the swage a and as this is done the punch or wedge-shaped member 2' enters between the inner face of the part 9 of the box and the adjacent face of the top swage a, when upon continued downward movement of the punch 71 the top swage n is forced laterally and this lateral movement forces the shell as into the cavity of the bottom swage and the swell b is formed upon the side of the shell, thus completing the shuttle. The punch z is then raised, the top swage moved to the left into the position shown in Fig. 5, so that the parts i g n and 72. may be easily taken out. Then in order to remove the shuttle from the bottom swage a, the bolts d e are removed and the counter plate 0 is removed from its recess in the bottom swa e a. Another shell is then inserted as be ore and the operation repeated. By this means all the shuttles will be formed exactly alike which is a great desideratum.
lVhat is claimed as new is In a device of the character described, a bottom swage having a cavity of the shape of the swell to be given to the shell, a counter-p1ate in said cavity, a vertically slidable and means for operating said Wedge-shaped box, a lateral pin on the lower portion theremember. 0 of, a top swage laterally movable on said In testimony whereof I afiix my signature pin, a Wedge'shaped member vertically movin presence of tWo Witnesses.
