MAlNSPRlNG-WlN DER FOR WATCH-MAKERS.

SPECIFICATION forming part ofiLetters Patent No. 349,291, dated September 14, 1886. Application filed December 26, 1885. Serial No. 186,776. (ModelJ To aZZ whom it may concern:

Be it known that I, PETER ZIEGEL, of Nash ville, in the county of \Vashington and State of Illinois, have invented a certain new and useful Improvement in Mainspring-\Vinders for Watches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, .and in which Figure 1 is a side elevation of the instrument, showing the spring holding pins retracted. Fig. 2 is atop view of the instrument as shown in Fig. 1. Fig. 3 is a side'elevation of the in strument .with the pins projecting from the face of the volute cam. Fig. 4 is a top view of the instrument as shown in Fig. 3. Fig. 5 is a front elevation. Fig. 6 is a section at 6 6, Fig. 7. Fig. 7 is a section at 7 7, Fig. 5; and Fig. 8 is a side view-of the rail guide, plate, or disk within the volute cam or head.

My invention relates to devices for winding the mainspring of watches, aiulinserting them in the barrels of the same, with a novel arrangement of adjustable gage pins that are regulated to the diameter of the barrel that holds the spring; and my invention consists in features of novelty hereinafter fully described,

Referring to the drawings, in which similar lettersillustrate like parts in the several figures, A. represents the pedestal of the instrument, and A the foot of the pedestal intended to be gripped in the jaws of a vise.

B designates the sleeve of the winder, which is provided at one end with a volute cam or head, G, having a radial guide plate or disk, D, hid within it. (See Fig. 8.) There are divergent slots D in this disk, through which d in a similar guide plate or disk, d, as seen in Fig. 6, the slots in both plates coinciding with each other. The face of the Volute head is formed of a rotary disk provided with curved or volute slots O", through which the aforesaid gage-pins also pass, and it will be seen that as this face is turned round the curved slots eX- pand or contract the area of the gage as desired, regulating it to the diameter of the barrel F that is to hold the spring G. The shaft H passes through the sleeve, and has longitudihold and con fine the spring.

nal motion sufficient to allow its end I to project through the face of the volute head. A pin, J, near the end of the shaft engages in the slot in the inner end of the mainspring.

K is the crank of the shaft, which, with its handle K, winds the spring.

' L is a pivoted cam-lever, which forces out the disk-frame that holds the gage-pins, thereby projecting them through the volute head to These pins are beveled on the outside of their points to allow an easy presentation of the barrel over them, and are recessed or half cut away on the inside to allow astraight backing for the mainspring, which is wound within them, and for which there is thus provided a recessed seat with a shoulder formed by the cut-away in the pin.

The operation of the winder is as follows: The instrument is placed in the vise, and the cam-lever brought to bear against the rear disk of the frame carrying the gage-pins, which are by that meanspushed forward through the volute camhead until they project sufficiently to clasp the mainspring as it is wound. The facedisk of the head, which is provided with volute slots that regulate the position of the gage-pins, is then turned round, and the curved slots are thus made to either expand or contract the area embraced by the gage-pins,regulating them to the diameter of the barrel. The shaft is then moved longitudinally forward until its end projects beyond the face-disk sufficiently to attach the slotted inner end of the spring to the pin near the end of the shaft. The crank is then made to turn the shaft until the spring is wound tightly against it. The barrel is next placed over the gage-pins, within which the spring is embraced, and the cam-lever being turned back to release its hold, the disk with the accompanying gage-pins are readily withdrawn, leaving the mainspring in the barrel.

It will be seen that by the novel device of the volute cam or head with its accompanying slotted disks and gage-pins one instrument may be regulated to conform to watch-barrels of any dimensions, the change being made in a few seconds without removal from the vise.

When it is considered that many barrels of varying diameter are being filled at the same bench and by the same mechanic, it is an evident feature ofgrea-t practical advantage to be able to effect the work without a change of instiruments.

I claim as 1nyinventi0n 1. In a mainspring-wintlcr, the combination of the sleeve B, supported on av pedestal, A, having a foot, A, with vertical sides for the vise-grip, and the volute head 0, with slotted disks 0, D, and (I, and gage-pins E E E, arranged therein to holtl the spring to a compass within the diameter of the spring-barrel, all substantially as tlcscrihetl, and for the purpose set lorth.
