struction of'watch movement holder whichia'cilitates a watch repairman lin vmaking vthe-necessary adjustments and replacements on watch movements.
Other objects will be more apparent as thedescription of the preferred embodiment proceeds.
In the drawings: Figure l is a top plan view of the work holder;
r-Figure 2 4is a side View partly in-section on theline 2-2-of'Figure 1; and
Figure 3 is a side View of the Awork-holder'in inverted position.
Referring to the drawings, the work-holder comprises four supportingand clamping pins or posts :I 0 adapted tobesimultaneously moved laterally and longitudinally withrespect to one another in orderto engage the edges of watch movements of diierent sizes. II and I2 represent cross frame members each of which comprises -a central plate i3 having `upper and lower parallel rods Id and Iisecur-ed thereto and projecting laterally therefrom. Each of the pins Il) is provided withtwoparallel bores I6 and I'I for slidably engaging vthe upper and lower rods I4 rand I5 respectively. vEach of the Yrins 'III is alsoip'rovided with upper and lower parallel bores`I9 and l" 20 extending at` an lacute `angle with respect to the bores IS and II and preferably at about a 60 angle. These latter bores I9 and 20 slidably engage the rods 2I and 22 which are inclined outwardly from opposite sides of a central work supporting frame 23. This frame contains a series of apertures 24 through which the rods 2I and 22 may be inserted, and the rods are retained in position in a suitable manner as by means of the small retaining pins 25. The frame 23 is slotted at 2S to receive and swivel the reduced central portion 21 of an adjusting screw 28 provided at one end with right-hand threads 29 and at the other end with left-hand threads 30. threaded portions engage correspondingly threaded apertures in the central plates I3 of the two cross frame members iI and I2 respectively. An adjusting knob 3I is secured to one end of the screw 28 and the center of the screw has en- These `2 larged portions 3'2 vand 33 forming'abutments `on opposite sides of the slotted frame 23.
In the construction as thus Vfar described,' when the screw v2'8 is turned by means of thev adjusting knob, the cross frame members II andI`2 4are simultaneously moved in opposite ylongitudinal dlrections 'and the pins I0 carried thereby `are caused to move both longitudinallyand laterally by means of their sliding engagement IWiththe angling rodsZ I and 22. l
Atene4 end of each of lthe pins Withere is :a shoulder '3d and a Central projecting portion v35. When it is desired to insert a watch movement 318 in the work holder wlth'the movement side upward, the 'watch movement is placed rv`on the shoulders '3d of the ll-pins I!! with the"dialisi`d`e 37 resting 'on said shoulders and thepins lllfare" tact with the balancewheelfof the Watch'mecha-- nism. Hence, I provide the pins lil at thefcppositeends thereof fromthe shoulders '3'4 ywith the conical heads '4U andv I also provide the work holder with a central supporting memberf'diwhich, as shown, consists of a'U-shaped member having slotted 4legs d2 embracing the opposite sides'ofthe frame 23. The `top offthe supporting member el lies in a plane which is spaced from the conical portions It of the pins at such a distance as to correspond with the thickness of a watch movement so that when the center of the movement side of the watch movement rests on the support, the peripheral edges of the opposite or dial side of the watch movement engage the conical heads lill. Thus by turning the adjusting knob SI, the pins I@ are moved inwardly so that the conical portions engage and clamp said peripheral portions and not only hold the movement securely in place but also, by reason of the conical angle, forces the movement downwardly into positive engagement with said support.
With the device as described, it will be apparent that it is readily adapted to secure a watch movement in position with the movement side upward by clamping between the projections 35 of the pins and where it is desired to support the movement with the opposite side upwardly, the entire work holder is turned over and the movement clamped between the conical pins 4B. Thus it will be readily apparent that I have provided a very simplied work holding mechanism which is adjustable to various sizes of watch movements and is capable of supporting the same with either side of the movement in position to be worked on by the repairman.
What I claim as my invention is:
1. A holder for a watch movement comprising a central supporting member, a series of rods extending from said supporting member in diagonal directions, four parallel pins transverse to said rods and slidably engaging the same, a pair of frames having rods slidably engaging said pins in a direction transverse to said diagonal rods, an adjusting rod rotatable in said supporting member and threadedly engaging the respective frames of said pair with threads of opposite hands.
2. A holder for watch movements and the like, comprising four corner posts, a central member between said posts, pairs of rods secured to and on opposite sides of said central member, the rods of each pair being parallel and having outwardly extending diagonal opposite end portions slideably engaging transverse bores in said posts, a pair of parallel rods extending transversely to said diagonal rods and slideably engaging bores in said posts which are at an angle to the aforesaid bores, work engaging and clamp-ing means at the end of each post, a rod swiveled in said central member to extend transversely to said transverse parallel rods and having respectively righthand and left-hand screw threaded opposite end portions, and nuts engaging said screw threaded portions and respectively attached to said transverse rods whereby a rotation of said screw threaded rod will simultaneously move all of said posts towards or from said central member.
3. A holder for watch movements and the like, comprising four corner posts, a central member between said posts, pairs of rods secured to and on opposite sides of said central member, the rods of each pair being parallel and having outwardly extending diagonal opposite end portions slideably engaging transverse bores in said posts, a pair of parallel rods extending transversely to said diagonal rods and slideably engaging bores in said posts which are at an angle to the aforesaid bores, engaging and clamping means upon opposite ends of each of said posts, for respectively engaging a watch movement in reverse positions thereof, each of said means alternatively constituting a supporting foot for its post, a rod swiveled in said central member to extend transversely to said transverse parallel rods and having respectively right-hand and left-hand screw threaded opposite end portions, and nuts engaging said screw threaded portions and respectively attached to said transverse rods whereby a rotation of said screw threaded rod will simultaneously move all of said posts towards or from said central member.
4. A holder for watch movements and the like, comprising four corner posts, a central member between said posts, pairs of rods secured to and on opposite sides of said central member, the rods of each pair being parallel and having outwardly extending diagonal opposite end portions slideably engaging transverse bores in said posts, a pair of parallel rods extending transversely to said diagonal rods and slideably engaging bores in said posts which are at an angle to the aforesaid bores, a portion of reduced diameter and restricted length projecting from one end of each post for engagement with a watch movement when arranged with its face side up, said movement resting on the shoulder beneath said reduced diameter portion, a reduced diameter portion of greater length extending from the opposite end of each post and terminating in a iiaring portion which in the reverse position of the structure constitutes a Work clamp for the movement With the dial side up, a bearing on said central member for supporting the movement in the latter position, the clamping means at opposite ends of each post alternatively constituting supporting feet for the post, a rod swiveled in said central member to extend transversely to said transverse parallel rods and having respectively right-hand and lefthand screw threaded opposite end portions, and nuts engaging said screw threaded portions and respectively attached to said transverse rods whereby a rotation of said screw threaded rod will simultaneously move all of said posts towards or from said central member.
