2. Claims.

The present; invention relates to improvements: in watchmakers. tools; and has reference more. particularly to a watch movement holder.

Qneoi the important; objects of the. present. inventionis to. provide. a. watch movement holder that is. capable of accommodating: various sizes and shape of watch movements and which hold the: same. securely and; conveniently while under-- some inspection and repair.

A further object of our invention resides. in the provision of a. watch movement holder that does; not require mechanical adjustment in order to accommodate various sizes of watch movements. 7

A still. further object. is to. provide a watch movement holder that will securely engage and support the watch movement in such a manner that the parts of the watch movement will be readily and easily accessible for repair and replacement. without interfering, with the operating parts of the holder.

Another object of importance: is to provide a watch movement holder that includes means; for positive; locking engagement with the lateral flange of they watch movement thus preventing any slippage or casual disengagement oi the watch movem nt wh n positioned on the. holder.

A still further object is to provide a watch movement holder that consists of relatively few parts, thus rendering the same inexpensive in its manufacture and readily and; easily operable.

Other objects and advantages of this invention will become apparent from the following description, when taken in connection with the accompanying drawing.

In the drawing forming a part of this specification and wherein like reference characters designate corresponding parts throughout the several views:

Figure 1 is a side elevation of our watch movement holder, showing a watch movement engaged and supported thereon;

Figure 2 is a top plan view of the holder;

Figure 3 is a longitudinal sectional view taken approximately on the line 33 of Figure 2;

Figure 4 is a vertical sectional view taken on the line 4-4 of Figure 3, and

Figure 5 is a similar sectional view taken on the line 5-5 of Figure 3.

In the drawing, wherein for the purpose of illustration, is shown the preferred embodiment of our invention, the numeral I designates generally the improved watch movement holder. This holder comprises a flat metal base plate 2 having downwardly extending

leg portions

3 and 4 at its respective ends.

A pair of spaced longitudinally extending slots 5 and 6 are formed in the base plate 2, as clearly illustrated in Figure 2 and the purpose thereof will be Presently apparent.

.An elongated rod 1 is slidablr disposed through registering openings; provided therefior in the leg portions; 3- and t. An: actuating; knob 8 is arranged: on the; forward end of the rod: 1;.

A block. 9' is. adiiustably secured on the slidable red I: by means: or the set; screw it and: thisbloclc engages with the underside of. the. base.- plate 2: for movement. therealonsz.

.A coil. sprin I I; encircles: the intermediate por tion of. the slidable rod t and is interposed lee-- tween. the. rearleg, portions and the: adiacent. face of the block. 9: for: ncrmal'lr'ur ingr the. rod and block: forwardly- Suitable; washers; l2 and 13' are arranged. on the: rod for cooperation with the, re;- spective ends or the coil. spring and therear le portion and block respectively.

Extending; upward-1p from the front. part. of the base plate 2. are the stationary pins t4 and t5i These pins may be attached-to the base platein any sui able manner and; in the instant case they are shown. as; being: riveted. to; the; base plate. although we do not desire to; be limited tn the; par ticularmanner in which. these pins; may be. secured.

These pins are, located: between;v the; forward ends oi the respective slots; in the base. plate: 2.11615 the forward end or the. latter and in alinement; with the respective.- slots, as: is clearly illustrated the drawing- The upper ends or these: stationary pins. are reduced. and. undercut to; forms the. shoulders. l6.- and; the beaded studs l'to A similar pair of pins I8 and I9 are removably secured to the top of the block 9 by suitable screw threaded

shanks

20 and 2| that extend downwardly from these last mentioned pins through the respective slots 5 and 6 and threaded into suitable sockets provided therefor in the block 9.

The pins l8 and I9 constitute slidable members that move across the top face of the base plate simultaneously with the movement of the slidable push rod 1 and the block 9 carried thereby.

The pin I 8 travels across the slot 5 and the pin l 9 moves along the other slot 6. These movable pins IB and I9 cooperate with the stationary pins [4 and I5, respectively, in the manner to be presently described.

The upper ends of the movable pins are also reduced and undercut, similar to the upper ends of the stationary pins I 4 and IE to form the shoulders 22 and the beaded studs 23.

In use, the knob 8 is pushed rearwardly, causing the spring II to be compressed and simultaneously moving the pins I 8 and I9 away from the pins I 4 and I5, thus permitting a watch movement of any shape or size to be positioned between the coasting beaded studs carried by the four pins, with the lateral flange a uniformly provided in the watch movement b resting on the shoulders I6 and 22 of the respective pins and the beaded studs contacting the adjacent peripheral portions of the watch movement.

When the watch movement has been properly positioned on the shoulders, pressure on the knob 8 is released, causing the spring I! to move the rod, block and movable jaws in a forward direction, thus assuring the watch movement being securely engaged and held between the pins of the holder.

With the watch movement supported on the holder, the same may be placed on a table or other support to permit the necessary repairs and replacements made to the watch movement, and this without any interference with the operating parts of the holder.

To release the watch movement from the holder, it is only necessary to push rearwardly on the knob and instantly, the movable pins are moved away from gripping engagement with the watch movement, thereby permitting the same to be readily and easily removed.

It will thus be seen from the foregoing description that we have provided a watch movement holder that is capable of accommodating various sizes and shapes of Watch movements and due to its simplicity can be readily and easily operated. Further, our device will be inexpensive, strong and durable and at all times positive and efficient in carrying out the purpose for which it has been designed.

While we have shown the preferred embodiment of our invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.

Having thus described our invention, what We claim is:

1. A watch movement holder comprising a base plate, leg portions depending from the end portions thereof, said base plate having longitudinal slots formed therein, a pair of stationary pins extending upwardly from the base plate adjacent one end of the respective slots, a pair of coacting movable pins operable through the respective slots in the base plate, means on the upper ends of the pins for engaging and supporting a watch movement, a slidable rod extending through said leg portions, 9, block secured on said rod, said movable pins being mounted on -the block, and spring means associated with the rod and holder for normally urging the movable pins toward the stationary pins.

2. A watch movement holder comprising a base plate, leg portions depending from the end portions thereof, said base plate having longitudinal slots formed therein, a pair of stationary pins extending upwardly from the base plate adjacent one end of the respective slots, a pair of coacting movable pins operable through the respective slots in the base plate, reduced beaded studs formed on the upper ends of the pins for engaging and supporting a watch movement, a slidable rod extending through said leg portions, a handle on one end thereof, a block adjustably secured on the rod and underlying the base plate, said movable pins being mounted on the block, and a coil spring encircling the rod and disposed between one leg portion and the block for normally urging the movable pins toward the stationary pins.
