WILLIAM P. HILLIOK, OF FULTON NEW YORK.

WINDING-ARBOR FOR STEM-WINDING WATCHES.

SPECIFICATION Iormmg' art of Letters Fatent No. 225,220, dated March 9, 1880.

Application filed J annar 26, 1880- To all whom it may concern:

Be it known that I, ILLIAM P. HILLICK, of Fulton, in the county of Oswego and State of New York, have invented a new and useful Improvement in Steam-Windin Watches, of which the following is a specification, reference being had to the annexed drawings, in whichv Figure 1 represents a longitudinal section. Fig. 2 represents a top-plan view of the arbor. Fig. 3 represents a cross-section on line .12.

My invention consists of a new pnslrpin and winding-arbor so constructed as to be readily adapted to the different styles of stemwinding watches, some of which are made with simply a socket to receive the windingarbor and others with a fixed arbor.

1 am aware that push-pins with arbors attached rigidly to them, or made all in one piece, have been heretofore used; but the use of such is limited to watches made with a socket to receive the arbor;

A is the push-pin, titted in any ordinary manner into the hub in the head-piece 15. It is made round, with a groove, in, around it, to receive the inner end. of the stemscrew which holds the push-pin in place.

The other end of the pin A is made with a square socket, U, of any desired depth. A screwthroaded hole is niade near this end of the push-pin, into which the set-screw o is fitted. This hole should be near the center of one of the square sides of the socket 0. This socket designed to receive one end of the removable winding arbor 1). This winding-arbor is made of a square piece of metal of proper length, and of such size as to fit into the socket U. Across one side of this arbor, near the inner end, a transverse groove or slot is out about one-halt way through.

The outer end of tho arbor is beveled ofi' slightly. The transverse slot a is so located that when the arbor is inserted in the socket G the slot will receive the point of the setscrcw 0, which, when screwed down, willhold the arbor in place in the socket and prevent its being withdrawn. This slot to is made wider than just what is needed to simply receive the end of the set-screw, because the case-spring of a huntingavatch is usually operated to open the case by pressure upon the puslrpin; and to allow this endwise movement of the push-pin independentof the an her this slot is widened.

, In a watolrinadc with a socket to receive the arbor the whole of my push-pin and winding-arbor is used, being inserted through the usual hole in the stem of the case, the arbor fitting into the socket in the movement, and the whole held in place by a set-screw through the stem in the usual manner, fitting into slot at; and in a watch made with a fixed'winding-arbor I remove my removable arbor and insert the socketed push-pin, the fixed arbor fitting into the socket O. I

In this manner my push-pin and removable winding-arbor can, at pleasure, be used in either style of stem-winding watches, and a jeweler is only obliged to keep on hand one kind of cases, while a different style of case is now required for each of the two kinds of stem-winding movements.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The above-described push -'pin A, constructed with the socket G in its inner end, and provided with the set-screw 0, extending into the socket, substantially as set forth.

3. In a stein-winding watch, the removable wimling-arbor l), fitting into the socket G in the push-pin A, and provided with a transverse slot, a, made wider than the point of the set-screw o to allow the cnd wisc movement of the push-pin independent of the arbor, constructed as above described.

3. In a stein-winding watch, the combination, with the winding mechanism, of the pushpin A, with the socket U in its lower end, and provided with a set-screw, o, and the 1'c1 novable winding-arbor D, constructed to fit at one end into the socket G and at the other. into the winding mechanism, and provided with the slot (0 to receive the set-screw 0, when constructed and operating together substantially as above specified.

In. witness whereof hand.

I have hereunto set my W. 1. HILLIGK. In presence of- U. W. Snrrn, U-nonen BEADLE.
