Application February 20, 1948, Serial No. 9,853

2 Claims.

By way of explanation, it might be stated that work holders commonly used for holding watch movements while they are undergoing repair, are not constructed in such a way that the watch movement while in the work holder maybe positioned in the clamp of the usual electric timing machine, and in order to time the movement, it is necessary to replace the movement in'the case and then place the movement and case in the clamp. In order to make a further adjustment, it is thennecessary to re-. move the movement from the case and again place it in the work holder. I

It is therefore the primary object of thepresent invention, to provide a work holder which will clamp a movement and hold the movement while repairs are being made, and then owing to the construction of the work holder, the work holder may be readily positioned within the clamp of the usual electric timing machine for the test. After the test has been made and it has been found that a further adjustment is necessary, the holder together with the movement may be removed and an adjustment made and the holder with the movement again replaced for the test, and timing, eliminating the necessity of removing the movement from the holder and replacing it in the watch case in order to again clamp the movement in the electric timing machine for further test or timing.

Another object of the invention is to provide a holder including an adjustable clamping member capable of clamping watch movements of various sizes.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangementof parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure l is a'fragmental elevational view of an electric timing machine illustrating the work holder constructed in accordance with the invention as clamped therein.

Figure 2 is an end elevational view thereof.

Figure 3 is an enlarged plan view of the work holder.

Figure 4 is a bottom plan view of the work holder. 7

Figure 5 is a sectional view taken on line 5-5 of Figure 4.

, 2 a Figure 6 is a sectional view taken on line 65 of Figure 3.

Referring to the drawing in detail, the work holder comprises a circular body portion 5providing an adapter to be clamped under the upper movable clamp of the conventional electric watch movement testing machine, said circular body portion being formed with a pair'of inwardly extended parallel spaced bores disposed transversely thereof, the bores being indicated by the reference character 6.

The work holder includes a movable section 1 which is provided with a curved cut-out portion 8 extending from the inner edge thereof and disposed adjacent to the upper edge of the movable section. This curved cut-out portion provides a curved jaw 9 that cooperates with the curved jaw l0 which is formed at the inneredge of the cut-away portion II that extends inwardly from the periphery of the body portion, in gripping a- Watch movement.

Secured to the movable section 1, are spaced headed pins [2 around which are coiled the springs I3, the outer ends of the springs engagin the heads 14 of the pins, while the inner ends of the springs rest against the end walls l5 of the bores 6. A finger piece [6 is connectedwith the movable section 1 and affords means whereby the movable section may be moved outwardly to clamp a movement of a predetermined size, between the jaws 9 and IU of the holder. Due to this construction, it will be obvious that watch movements of various diameters may be conveniently and securely clamped to the holder for convenience in repairing the movement.

The construction of the circular body portion is such that it provides an adapter which may be conveniently clamped within the adjustable clamp of an electric timing machine, as shown and described in Patent No. 1,905,778, dated April 25, 1933 and which in the present showing is indicated by the reference character A, the clamp of the conventional testing machine being indicated generally by the reference character B, and

- including the upper movable section C that under normal conditions, bears against the watch case in which the movement is held, and which movement is being timed or tested.

Due to the construction shown, the curved circular body portion 5 of the work holder forming the subject matter of the present invention may be readily clamped within the clamp of the electric timing machine, eliminating the necessity of removing the movement from the work holder and repositioning the movement in the watch case, which is necessary when using conventional work holders, in order to make the proper test or time the movement. After the testing or timing of the watch movement, the work holder together with the watch movement may be removed and adjustments made On the works or movement, eliminating the necessity of removing the movement from the holder at any time during the repairing or timing of the movement.

It might be further stated that the jaws 9 and In of the movement clamp, are formed with beveled inner edges that fit over the upper edge of the movement to securely grip the movement and prevent the movement from falling from the clamp when the work holder is in use.

The opposite surface of the work holder isprovided with a plurality of shoulders H, the shoulders defining circular recesses for the reception of watch movements of various diameters.

Rows of various sized openings indicated at 18 are formedin the upper surface of the body of the work holder, and are provided to receive various screws which are removed from the movement, so that the screws of a particular movement may be'retained with the movement.

What is claimed is:

1. A removable adapter for a watch movement testing machine, comprising a body, a watch movement clamp formed on the edge of the adapter, disposed eccentrically of the adapter, said clamp including a stationary jaw forming a part of said body, a movable jaw cooperating with the stationary jaw for gripping a watch movementand means forv moving the movable 4 jaw relative to the stationary jaw, securing the watch movement to the adapter.

2. A removable adapter for a watch movement testing machine, comprising a circular body, one edge of the body being cut away providing a stationary clamping jaw, a movable section having a cut-away portion providing a movable jaw cooperating with the stationary jaw securing a watch movement to the adapter, means for moving the movable jaw relative to said stationary jaw, and said jaws being disposed eccentrically of the circular body.
