PALLET JEWEL SETTER John Vinardi,

Application August 19,

10 Claims.

This invention relates to a pallet jewel setter, the general object of the invention being to provide a device whereby the watchmaker or watchrepairer can, by the use of a three point system, determine any escapement error in the watch; i. e., any disalignment of the escapement wheel pivot hole center, the pallet arbor pivot hole center and the balance jewel center, and by which distortions of or bents or dents in the escapement l lever of the watch can be detected and also the degree of such disalignment or distortion can be ascertained so that a corresponding allowance may be made in setting the pallet jewels, thereby setting the pallet jewels on either side of the line of center so as to compensate for any such disalignment or distortion.

A further object of the invention is to enable a watch-maker or watch-repairer to set varying sizes of pallet jewels having either straight line escapements or right angle escapements with the one device and specifically to enable the setting of pallet jewels in watches of the type varying from the small modern bracelet straight line lever watch escapement to the 18 size detached lever type, and further to enable, by use of the same device, the setting of pallet jewels for right angle escapements consisting of either double roller or single roller escapements.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. g

Figure is a section on the line lit-Ill of Figure 3.

In these drawings the numeral it indicates an angle-shaped base or supporting member having a forked bracket l9 adjustably connected for rotary movement to its upper end by a screw l9 and a base plate 3| is attached to the outer end of the prongs of the bracket by the screws 5' engaging threaded holes in the base plate. This plate is preferably of the shape shown in Figure 1 with a short and straight side edge at each of its four corners, three of these side edges having slots 35 therein while the fourth has the graduating marks 38 thereon. A bridge member 2 extends upwardly from the base plate and this bridge member is formed of the long part 2' and the short part 2", these parts being horizontally arranged and each part is formed with a depending portion having a right angle foot part 3' and these parts 3' are connected with the base plate by screws 3 which pass in threaded holes in the base plate 3!. A substantially U-shaped bridge member A is movably supported by the bridge member 2 by having the upper horizontal part of the bridge member 4 slidably arranged between the

parts

2 and 2" of the bridge member 2. The inner end of this part of the bridge member 4 extends beyond the inner end of the short part 2' of the bridge member 2 but the inner end of the long part 2 of the bridge member 2 projects beyond the inner end of the upper portion of the bridge member 4. The bight of the bridge member 4 extends downwardly through one of the slots 36 in the base plate with its other limb located under the base plate and paralleling the same. The two parts 2' and 2" of the bridge member 2 are fastened together by screws or other fastening means as shown andthey form a guideway for the upper limb of the bridge member 4. An opening 5 is formed. in said upper limb of the bridge member 4 and a screw 25' has its ends held against movement in the end walls of this opening and a nut 25 is threaded on the screw and passes through slots in the

members

2 and 2 of the bridge member 2 so that by rotating this nut in one direction or the other the bridge member 4 is moved inwardly or outwardly according to the direction. of turning movement of the nut. The bridge member 4 is held in adjusted position by a set screw 4" and a friction spring is placed in a groove in the upper limb of the bridge member 4 and bears against a part of the bridge member 2.

The ends of the upper and lower limbs of the bridge member 4 are provided with the vertical- 1y arranged bearings 29 and 32 for the

depthing points

5 and 6 and the long member 2 of the bridge member 2 is provided with vertically arranged bearings 28 for the depthing point 1. Locking means 9, II and 12 are provided for holding the points 5, l and 6 in adjusted position and each of these means includes a nut located in a slot in a bridge member and threaded on a screw shaft arranged in a plain bore in the bridge member and held against rotary movement so that when the nut is turned in one direction or the other the screw shaft is moved longitudinally into engagement with a point or out of engagement therewith. A small plate 9' bears against a flattened part of each screw shaft to hold the screw shaft against turning movement while permitting it to slide, each plate being held in place by a pair of screws as shown. Depthing points of different sizes can be used in the device.

An index lever l3 has its inner end connected by screws or other fastening means to the tubular reduced and circular upper end of a member 311, said reduced upper end of the member 3!) being rotatably arranged in a hole in the base plate 3 l, as shown in Figure 6 and a depthing point 8 passes through a vertically arranged bore in the member 36 and is held in adjusting position by the locking means Ill which are similar to those before described and include a nut on a threaded screw shaft supported for longitudinal movement in the member 30. Each of these

depthing points

5, 5, T and 8 has one end pointed and the other end is cupped and has a hole adjacent the cup as is usual in devices of this nature.

The lever l3 has its inner portion of considerable width and this part operates in an opening in the base plate 3| and this part has a slot therein and a groove, said groove receiving for sliding movement the index plate M which also has a slot therein registering with the slot of the lever l3 and it also has a pair of holes 15 therein and a center line 28' as shown in Figure 9. The outer portion of the lever l3 passes under a portion of the base plate 3| with the outer end of the lever l3 bent upwardly and then inwardly into hook shape so that this hook portion will pass over that part of the plate 3| which carries the graduation marks 38, as shown in Figures 1 and 2 with the end of the upper portion of the hook part pointed to act as a marker on the graduations. A small spring [3' is carried by the hooked part of the lever 13 and. frictionally engages an under part of the plate I to yieldingly hold the lever in adjusted position.

A carriage I6 is slidably arranged on the lever I3 and is held in adjusted position by a bolt 2 which passes through the slots in the plate I l and in the lever l3 and by moving this carriage, after loosening the bolt, to a certain extent and then continuing this movement the plate M is moved in the slot of the lever 13 and the parts are held in adjusted position by tightening the bolt 26. The carriage has pivoted thereto the pair of substantially L-shaped levers I! and each lever has an upstanding part at its outer end for engaging a groove in a small wheel 5!, these wheels being carried by threaded stems extending outwardly in opposite directions from an upright 52 on the rear of the carriage. Thus by turning one of these wheels 5| it is caused to move inwardly or outwardly on the threaded stem and thus the wheel causes rocking movement of a lever I1. These levers I! act to hold a watch lever on the lever I3 and by adjusting the carriage on the lever l3 various sizes of watch levers can be held on said lever I 3.

A turret supporting plate 55 has a part extending under the base plate 3| and said plate 55 is adjustably held to the base plate by a screw 35 engaging a threaded hole 33 and a pin 56' on the plate 55 engaging another one of the holes 33. This turret supporting plate 55 may be connected with that side of the base plate to which it is connected as shown in Figure 1 or it may be connected to the opposite side if desired. A plate 36 having a circular opening therein and a split leading from the opening through a side edge of the plate is fastened by screws or the like to the outer part of the plate 55 and a shaft 22 extends into a recess in the plate 34 and is rotatably supported by the plate 34 and said shaft has a worm 39 thereon meshing with the worm gear 23 located in the circular recess and connected with the lower end of a turret 56 which has a flanged lower end located in the circular recess. Thus by turning the shaft 22 by its knurled head the turret can be partly rotated. The slit or split in the plate 34 makes a part thereof slightly flexible and the portions of the plate through which the split passes having threaded holes therein for receiving the threaded part of the turn screw 24 so that by turning the screw in one direction the slitted parts are moved toward each other so as to clamp the worm 39 and the gear 23 together to lock the parts against rotary movement. Of course, by turning the screw 24 in the opposite direction the parts will be loosened so that the turret will be turned when the shaft 22 is turned. An elongated tubular member 51 passes vertically through the turret 56 and has a bore passing longitudinally therethrough, the lower part of which is screw-threaded and a threaded shaft 58 passes through the bore with its upper end enlarged and unthreaded and provided with a knurled head 2|. Thus by turning the shaft 58 by the head ZI the engagement of the threaded part with the member 51 will cause longitudinal movement of the member 5! as this member is held against rotary movement. The shaft 58 is held against longitudinal movement by having a head 59 on its lower and rotatably arranged in a recess in the plate 55 but held against vertical movement in said recess.

A portion of the turret is cut away at one side thereof to expose a portion of the member 5'! and a horizontally arranged plate 40 is fastened to thisexposed part of the member 51 so that the plate 43 is moved vertically when the member 57 is moved vertically by turning the shaft 58.

A pointer bar 20 passes through a passage in the plate 4!] and said bar has a threaded portion 23 which is engaged by a nut 31 passing through a slot in the plate 40 so that by turning this nut 3'? the bar 26 is moved longitudinally in the plate 40. The bar 20 is locked in adjusted position by the locking means 6E], see Figure 7, said means including a nut passing through a slot in the plate 40 and a threaded shaft longitudinally movable in the plate 49 and moved by turning movement of the nut 60, this locking means being similar to that before described and used for holding the depthing points in adjusted position. This rod or bar 20 has its free end bent downwardly and pointed as shown in dotted lines in Figure 4.

As will be seen by turning the shaft 22 the turret with the plate 40 can be partly rotated and by turning the shaft 58 the plate 40 can be raised and lowered and byturning the nut 31 after loosening the locking means 60 the rod?!) can be projected or retracted.

Points and I are used to determine the depthing of the escapement wheel pivot and the pallet arbor pivot, the point 5 being adjusted toward or away from the point i to center the points over the escapement wheel pivot and pallet arbor pivot by moving the bridge member 4 by means of the nut 25 and screw 25. The depthings can be taken from the lower or upper watch pla'te. After the depthings are obtained the points 5 and 1 are reversed to bring the ends containing the small cavities lowermost and the

points

5 and 6 are adjusted'vertically to hold the escapement wheel pivot and the points i and 8 are adjusted to engage the pivot of the watch lever. The levers ll are adjusted by' turning the wheels 5| to cause said levers to hold the watch lever on the line of center 28 of lever l3 of the device. In a single roller escapement, the. guard pin of the watch lever is dropped into the hole in the index plate M to align the watch lever with the line of the center 28. The pointer bar is adjusted to determine the depthing of the balance stafi pivot center of the watch from the lower plate of the watch. Then after the watch plate is removed the pointer bar is lowered on the line of center 28 on plate M to indicate whether or not the balance staff pivot center is on the line of center 283 If it is not then the lever i3 is adjusted and the g'raduations 38 will indicate the degree the pivot hole or bearing is oil-center as indicated by the depending and ponited lower end of the bar 2i! on the plate M. This will enable the pallet jewel or jewels to be set to compensate for the amount the pivot center is oil the line of center.

Also by placing the watch lever on line of center 28' on plate I4 and'then operating the index lever I3 it can be determined whether the watch lever is distorted, dented or bent. Lever I3 is moved until the escapement wheel tooth drops from the impulse face of the pallet jewel upon the receiving pallet jewel and cognizance taken of the degree as shown by the graduations 38 at which such dropping occurs; The lever 13 is then moved in the opposite direction until the escapement wheel tooth drops from the discharging pallet jewel and the degree of such drop ping is also taken cognizance of as shown on the graduations 38. The difference, if any, between the two noted degrees of each dropping is the amount of distortion, dent or bent in the watch lever and appropriate allowance may be made for such difierences in setting the jewels. As before stated the watch lever is held in position on the line of center 28 by the points I and 8 and the levers l! and by adjusting the carriage Iii which carries the levers I? said lever can be made to hold various sizes of Watch levers. These levers I! are independently adjustable and are thereby enabled to be adjusted to hold the watch lever firmly and accurately on the line of center 28 throughout the setting of the pallet jewels.

By removing screws 3 the entire bridge assembly including the

bridge members

2 and 4 and the depthing points 5, 6 and 1 can be placed at a right angle by placing the screws 3 in other holes 33. Then the device can be used for setting right angle escapement pallet jewels. Turret assembly can also be moved to opposite sides of the base plate as before stated. The invention also contemplates the use of a depthor rotor l8 when desired. This member 18 is attached to the lower end of the point 5 and a knurled head 5' is attached to the upper end of this member 5 so that it can be readily turned. This member I8 is formed with the lips 21, as shown in Figure 5. This member I8 is used when only slight adjustment of the escapement lock of the pallet jewels are desired without taking depthings from the watch plate as above described. By holding the watch lever in depthing points 1 and 8 and setting the rotor lips 2'! so as to bite the pallet jewel which is being set and by setting the index lever IS on the desired degree there is obtained an accurate adjustment between the lock of the escapement wheel tooth and the pallet jewel or jewels. This member i8 is attached to the point 5 by a set screw or the like and it has a hole therein for receiving the upper end of the point 6 as shown in Figure 6.

In starting to use the device the carriage i5 is removed by taking out the carriage bolt and bar 2!] is swung to the right in Figure 1. Point 5 with rotor I8 is removed and. a point sine ilar to that shown at l is substituted for point 5, with the pointed end lowermost. The watch plate is then placed on lever 53 and the point which has been substituted for point 5 is centered on the escape wheel pivot hole center of this watch plate after which the point is'loclred in adjusted position by the locking means i i and point I is centered to pallet arbor center. Then bar 20 is swung to a position where its depending end will be over the center of the balance wheel pivot hole or over the jewel bearing if one is placed in said hole. After the depthing is taken bar or rod 20 is raised by turning shaft 53 and the watch plate removed and then the bar or rod 20 is lowered to place its depending end adjacent index plate l4 and then lever 53 is adjusted to place the line 23' under the depending end of the bar or rod 20, if said line is not al ready under said depending end. The marker on the outer end of lever is will indicate on the scale 38 the number of degrees the depending end of bar 2!! is on either side of the line of center 28.

After the readings are taken the

points

5, 7, 6 and 8 are reversed to bring their pivot receiving ends into operative position and the watch lever put in place with the points I and 8 holding the pallet arbor of the lever and the

points

5 and 6 holding the escapement wheel. Then carriage I6 is replaced and the wheels 5! are turned to cause the lever l! to grip the watch lever with the parts on the line of center 28. If the watch lever is for a single roller escapement, the guard pin of the lever is inserted in hole [5, but if the lever is for a double roller espacement then it is not necessary to use the guard pin in the hole [5.

When the parts have been adjusted to have the escapement wheel and pallet arbor, with the watch lever held on line of center 28' and the parts held securely in this position, then the watchmaker or repairman can set the pallet jewel, allowing the necessary lock and drop.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.
