' WATCH MOVEMENT HOLDER Filed Aug. 22, 1945 ZJMW Mary/ 2 [ff Patented Feb. 1, 1949 UNITED PATIENT QFj-F'ICZE WATGHMGVEMENT HOLDE-R .Manvin-Efllay, High-Point, C. hpin; menau ust/2.2, 1945, sernrmve aocc This invention relates to 'what are known .in the-art-as iriovemen-t holders, such devices being used to hold watch movements when removed from the case in order that the watchm akerimay inspect and :repainthe same. I

n number of such movement h'o'lders fa re :in use today bi'itdepend largelyonadjustments'iand adjustment *devices that are. not positive =in their operations. Some of these movement :holders relywn friction, others on springs andstillothers on both springs and irritation. of courseineither springs norrfriction give anyipositiveadjustment.

There is another class of such holders inwhicha single pair of "jaw-s are positively moved toward and from each other: ln 'this class of movemen't holders-spaced means, which are fixed on such jaws, are used to grip the movement at the spaced points on opposite "sides. *Such holders do not provide for the positive adjustment of such jaws.

The principal object of the present inyen tion is to provide a movement holder wherein four jaws are employed which are arranged in pairs. and wherein positive adjustment may be made to the relative positionsnfithese jaws;

:Aseconddmportant .obj ect.of*the:invention1is to provide a movement holder'which maybe "used tor the smallest type .of Wristwatches, $013 constructed in .proper .size, may be used v for Watches .of larger dimensions. .5 third important object :of the invention is to provide a movement holder wherein the jaws are so constructed and arranged as to securely hold a. movement without the possibility of its slipping out and in such manner that, under the skill of the watchmaker, no undue pressure or distortion will be given to the lower plate of the movement which is gripped by the holder.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel features of construction and combinations of parts presently to be specifically described with relation to the accompanying drawings, and particularly claimed,

In the accompanying drawings like characters of reference indicate like parts in the several views and:

Also the 1 1o ds 5115 will; Lander-movement rofsthe ipairsv of ijaws it-award: each other, pass into the cut away portions and thus not interfere with the closing closely of the jaws l6. On top of the body of each of these jaws is a lug 20 having an upwardly extending and slightly overhanging gripping portion 2|. Thus there is provided four jaws and in order to move the jaws of each pair toward and from each other a screw 22 is fitted in a threaded opening in one lug 20 of each pair and this screw has a cylindrical portion 23 revolubly fitted in the other lug 20 of the pair and provided with a head 24 on the outer side of the lug and a collar 25 on the inner side of the lug. Thus rotation of a screw 22 will move the jaws l6 of the pair toward or from each other as desired.

It will now be obvious that not only may each pair of jaws be adjusted positively toward the other pair but also that the jaws of each pair may be adjusted positively toward and from each other. Furthermore it will be observed that for irregularly shaped watches the jaws of one pair maybe adjusted at a different spacing than the I jaws of the other pair. When a watch movement is placed with its plate on the top surface of the 3 lugs 20 a manipulation of the screws II and 22 will be made by the watchmaker so that the plate will .be firmly gripped and positively held without undue and injurious pressure being brought thereon.

What is claimed, is:

1. In a watch movement holder, a pair of rectangular plates arranged in parallel spaced relation, a screw extending centrally through said plates, said screw being journalled for free rotation and held from longitudinal movement through one of said plates and having threaded engagement with the otherplate, a pair of jaw members for each plate, each pair of jaw members having confronting faces and slots extending from these faces into the members, each plate having its ends fitting into the slots of a respective pair of said jaw members, and a screw for each pair of jaw members having a head portion freely revoluble in and held from movement through one jaw member of the pair and having threaded engagement with the other member of said pair. a

2. In a watch movement holder, a pair of rectangular plates arranged in parallel spaced relation, a screw extending centrally through said plates, said screw being journalled for free rotation and held from longitudinal movement through one of said plates and having threaded engagement with the other plate, a, pair of jaw members for each plate, each pair of jaw members having confronting faces and slots extending from these faces into the members, each plate having its ends fitting into the slots of a respective pair of said jaw members, a screw for each pair of jaw members having a head portion freely revoluble in and held from movement through one jaw member of the pair and having threaded engagement with the other member of said pair, and a pair of guide rods fixed in one of said plates and slidably extending through the other'plate.

3. In a watch movement holder, a pair of rectangular plates arranged in parallel spaced relation, a screw extending centrally through said plates, said screw being journalled for free rotation and held from longitudinal movement through one of said plates and having threaded engagement with the other plate, a pair of jaw members for each plate, each pair of jaw members having confronting faces and slots extending from these faces into the members, each plate having its ends fitting into the slots of a respective pair of said jaw members, a screw for each pair of jaw members having a, head portion freely revoluble in and held from movement through one jaw member of the pair and having threaded engagement with the other member of said pair, and an upwardly extending lug projecting from the upper end of each jaw member and having a movement supporting face and angularly disposed movement gripping faces.

' 4. In a watch movement holder, a pair of rectangular plates arranged in parallel spaced relation, a screw extending centrally through said plates, said screw being journalled for free rotation and held from longitudinal movement through one of said plates and having threaded engagement with the other plate, a pair of jaw members for each plate, each pair of jaw members having confronting faces and slots extending from these faces into the members, each plate having its ends fitting into the slots of a. respective pair of said jaw members, a screw for each pair of jaw members having a head portion freely revoluble in and held from movement through one jaw member of the pair and having threaded engagement with the other member of said pair, an upwardly extending lug projecting from the upper end of each jaw member andhaving a movement supporting face and angularly disposed movement gripping faces, and a .pairv of guide rods fixed in one of said. plates and slidably extending through the other plate, said jaw mem-. bers having notches extending from their confronting faces and embracing said rods upon closing of the jaw members of the pairs on each other.
