MACHINE FOR POLISHING WATCH-PINIONS.

SPECIFICATION forming part of Letters Patent No. 417,377, dated December 17, 1889.

Application fi November 9,1885- Serial No. 182,317. (No model.)

To all whom it may concern:

Be it known that I, CHARLES V. WOERD, of Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Polishing Watch-Pinions, of which the following is a full, clear, and exact description.

This invention relates to a machine more particularly designed for the polishing of leaves of watch-pinions to be used in a watchmovement, and will be particularly described in relation thereto; but, as will appear from the description which follows, it is in many respects applicable, with a change of simple character, to the cutting of pinions.

Machines have heretofore been constructed for the purpose of polishing watch-pinions; and the main objects of the present invention are to soimprove on such machines as to greatly increase their Working capacity as to the number of separate watch-pinions which can be polished therein within a given time, and to enable the same machine to be readily changed and adapted to the polishing of watch-pinions having a different number of leaves. I

The accomplishment ofthese ends is more particularly the objects of this invention; and

the invention, in substance, consists, first, in the combination, with a-machine of otherwise suitable construction for the polishing of leaves of watch-pinions, of a wheel or equivalent device constructed with pockets in a series around its periphery at' equal distances apart and each suitably adapted to receive and hold apinion for its leaves to be polished and the Wheel arranged for an intermittent movement and for a rest after each movement, and all in such manner as to bring each watch-pinion placed in said pockets successively into position for its leavesto be polished by the polishing appliances of the machine, the pinion in each pocket being suitably rotated to present its separate leaves, one after another, to the action of the polishing appliances; second, in a machine of suitable construction and arrangement of parts to polish the leaves of a Watch-pinion, to rotate the pinion so being polished for presenting its separate leaves, one after another, to the action of the polishing-tool, and to withdraw said polishing-tool from the pinion for said pinion to be rotated, as stated, and for re- 'moving it and replacing it with another, the combination of mechanism for operating said pinion holder, polisher, and rotater, as aforesaid, constructed and arranged so as to be capable, without change thereof, of operation upon pinions of varying numbers of leaves, and mechanism for communicating motion between said operating mechanisms to withdraw the polisher from and to rotate the pinion and to operate the pinion-holder, which is constructed and arranged so that by a change of one of its component parts the machine,

tate a pinion and to place its pinion polisher and rotator in and out of operative position and without change of any such operative parts, can be adapted for the polishing of pinions having different number of leaves;

in all its operative parts to polish and ro-' third, in a mechanism such as hereinafter particularly described and claimed for rotating the watch pinion for the presentation of its several leaves to the polishing appliances; fourth, in a yielding holder which is located in each pocket of the pocket-wheel to receive and hold a watch-pinion and allow it to be rotated for presenting its separate leaves, one after another, to the action of the polishing mechanism; fifth, of an arrangement, as hereinafter particularly described, of the polishing mechanism to secure its adjustment in its work upon the pinion to be polished by it and to place it out of operative position without detaching it from the machine; sixth, of a polishing-tool composed, of a circular metal disk and means to continuously rotate it and to reciprocate it, all as hereinafter particularly described.

In addition to the above, the invention consists of other improvements, all of which hereinafter fully appear, and are set forth in the claims. i

The present improved machine is illustrated in the drawings forming part of this specification, in which Figure 1 is a plan view. Fig.1 is a detail view, as hereinafter appears. Fig. 2 is a transverse vertical section from front to rear, line 2 2, Fig. 1, with the parts back of the sectionline in elevation and some parts in vertical section, as hereinafter appears. Fig. 3 is a front elevation. Fig. 4E is a horizontal section, line a 4, Fig. 3. Fig. 5 is a vertical section, line 5 5, Fig. 1, through the frame-work of the machine, with some working parts in cross-section and others in elevation,as hereinafter appears. Fig. 6 isahorizontal section, line 6 6, Fig. 5. Fig. 7 is a view in detail, partly in perspective and partly in vertical section, and made more particularly in illustration of the special parts of the machine, by which the machine is made capable of being readily changed for the polishing of watchpinions having a varying number of leaves. Figs. 8,9,and 10 are enlarged views in detail. Fig. 8 is partly in section and partly in side View, and all in illustration of the holders for the watch-pinions, of the turning devices for each pinion so held, and an adjustable holder or carrier for said pinion-turning devices, as hereinafter more fully appears.

In the drawings, A represents the framework of the machine, which consists, principally, of a platform or table B, supported at its front or rear by uprights O, and is otherwise suitably constructed for the support of the various working and stationary parts of the machine, as will hereinafter appear, and the whole, preferably, is carried by a bedplate or bench in common therewith.

The polishing device of the machine consists of a continuously-rotating disk D, (shown in duplicate,) and the edge a of each disk is its polishing part, and it is shaped to act on the whole extent of the surfaces of the leaves of the pinions, between which it is entered, Fig. 8. Both disks D are clamped between collars E at one end of a horizontal shaft F, which is arranged to turn in suitable bearings at one (the outer) end G of thehorizontal arm H, and which at its other end is pivoted and swings upon a standard J of a plate K, arranged to slide forward and backward in a dovetail groove L of the upper side of the table B, and in a direction at right angles to the axis of rotation of the polishing-disks D,

and preferably made of metal. These disks bot-h rotate in vertical and parallel planes. The shaft F of the polishing wheels or disks D has a pulley M attached to it, and this pulley is connected by belt (not shown) to a pulley (not shown) of a driving-shaft. (Not shown.)

N is a pitman-rod connecting one end of the slide-plate K with the crank-pin O of a continuously-rotating wheel or head P, which is carried by a shaft Q and turns in suitable bearing-blocks R of a standard S, and has a pulley T, by which to connect. it for being driven.

The pitman-rod N, preferably and as shown, is constructed so as to be lengthened and shortened at pleasure, and again the crankpin 0 of the head P, which the pitman-rod connects with the side plate K, and said head, preferably and as shown, are constructed and arranged to enable the crank-pin to be ad-- justed in relation to the axis of rotation of its head P, all in a well-known manner, and therefore needing no particular description herein, and the purpose of the whole is to secure the adjustment thereof to the required or desired length of forward and backward slide of slide-plate K, and of polishing wheels or disks D, carried by it, as has been described, and to adapt the forward and backward travel of the polishing wheels, and while under rotation, to the length of the leaves of the watch-pinions to be polished by them.

U is a thumb-screw, which screws through the hinged arm II, carrying the polishingdisks D, and has a bearing against the head I) of the vertical lift-pin V, passing loosely' through the slide-plate K, and an elongated opening (not shown) in the table B and below said table, where it rests upon the upper side of a horizontal lever X, which is fulerumed at d to a fixed post Y of the table, and this lever continuously rest-s at its free end upon the periphery of a vertical and continuouslyrotating cam-wheelZ, which is constructed and arranged and operates thereon, as hereinafter described.

The thumb-screw U holds the polishingdisks D, carried by the hinged arm H, in their proper positions or at their proper height, and by turning it in and out of said arm the height of said disks can plainly be regulated and the disks made secure at the height desired, and all for the purpose of compensating for the wear of the polishing-disks and enabling them to be placed in their proper relation to the wateh-pinions to be polished in the machine, and which will hereinafter fully appear. A is a vertical wheel carried by a horizontal shaft- B turning in suitable bearings of vertical standards 0 of the bed-plate of the machine. This wheel A has a series of equivalent pockets D around its periphery, and it is the carrier for the watch-pinions E the leaves of which are to be polished, and by which to present them to the polishing-wheels one pair after another. A watch-pinion is placed and held in each pocket, as hereinafterdescribed. This pocket and carrier-wheel A for watch-pinions turns iii a plane at right angles to the plane of rotation of the polishing-disks, and it is placed below said disks and in a position for the proper operation of two polishing-disks at one time in relation to two watch-pinions carried in separate pockets of the wheel, and as the same hereinafter fully appears.

The poeket wheel is intermittently rotated, and it carries an index-wheel F having around its periphery or edge a series of equidistant notches f, one notch for every other pocket D of the pocket-wheel A g is a spring-pawl at the upper end of a vertical arm G fulerumed at its lower end h to a block H of the bed-plate. \Vith this spring=pa-wl g'engaged with a notch f of the index-wheel F and the arm G carrying it swung in one direction and against the tension of a spring 70, connected thereto and to a fixed pin Z, the index-wheel will be rotated in a corresponding direction, and on the return swing of said arm G said pawl, escaping from the notch of the index-wheel with which it was engaged, then passes freely backward over the peripheryof said wheel and again becomes engaged with the notch next in order in the series of notches thereof.

m is a pawl backed by a spring a and fulcrumed upon the stationary block 11 of the bed-plate.- This pawl on also is for engagement with a-notch of the index-wheel and so as to hold the sameagainst movement in either direct-ion until it is released therefrom.

The vertical lever G carrying operatingpawl g for the index-wheel, has an arm J projecting from one side thereof and into the plane of rotation of a dog KZ-and also an arm L projecting therefromand in position'in the swing of said lever'G which carries the index-wheel forward to strike against the retaining-pawl m and release it and hold it released from the index-wheel while said wheel is being turned under the said swing of the lever G and to leave said-retaining-pawl free to become again engaged-with the indexwheel on the return movement of said lever, and in which movement the operating-pawl g, carried by it, is traveling backward over the periphery of the index-wheel.

The dog K before referred to, is carried by a shell M turning loosely on a horizontal shaft N whichtu'rns in suitable bearings of a standard 0 fixed to the common bed-plate,

' tinues to rotate,'and so on, as before.

and of the side uprights O. This. shaft N also carries the cam-wheel Z, upon the edge of which, through a lever X,rests the vertical pin V, having the carrying-arm II for the polishing-disks D, resting upon it through the thumb-screw U, all as has been before described. The edge 1 of'the cam-wheel has a series of equidistant and correspondinglyshaped'cam projections or toes wand as the cam-wheel rotates each of these toes, operating on the lever X and through lift-pin V, resting thereon, and thumb-screw U, resting on said lift-pin, lifts the hinged arm H, and through it the polishing-disks D, all of which, on the escape of the cam-toe, return to their normal'position and there remain until again lifted by'the action of the cam-toe next in the order of their series as the cam-wheel con- This lifting of the hinged arm H, and through it of the polishingdisksD, is for the purpose of removing said disks from their operative and polishing position ona watch-pinion E so as to leave the watch pinion free to be rotated to present another of its leaves to the polishishing-disk, or to permit the pocket-wheel carrying them to be rotated for the purpose of presenting another pair of watch-pinions to the polishing wheel or disks, as hereinafter more fully appears. The shell M turning loosely upon the horizontal shaft N and which carries the dog K for operating the lever G by and through which the'indexwheel F and pocket-wheel A carried by it, are intermittently rotated, as has been described, also carries a dog P to lift, on each rotation of the shell M a horizontal arm Q which turns upon a stationary fulcrum-pin I, and in its normal position rests on a fixed abutment 2?. This arm Q supports two parallel and horizontal finger-rods R provided for turning the watch pinions (the leaves of which are to be polished) in their pockets of the pocket-wheel, so as to present another leaf thereof to the action of the polishing-disks,- all as will hereinafter more fully appear.

The shell M has a sleeve-extension S along the shaft N which carries it. This sleeve S ends on the outside of one of the end uprights 0 of the table B, where it is provided with gear-wheel T and said shaft N outside of said gear-wheel, is provided with a corresponding gear-Wheel U These two gear wheels T U one U on the shaft N and the other T on the shell-sleeve S are geared together through a train of gear-wheels. This train consists of a gear-wheel V which is of the same size as gear-wheels T U and turns on a fixed stud and directly meshes gearwheel Z, and furthermore as and for a purpose as will hereinafter appear. The shell M and cam-carrying shaft N have a Wormgear Y which meshes a worm (not shown) of a shaft (not shown) driven in any suitable manner, and thus said shaft N and the shell geared together, as described, are both driven with a continuous rotating motion, but the shell with a movement slower than the camwheel, because of the reduced gear-wheel X of the train of gear-wheels described, and which gear meshes the intermediate gear- Wheel Z meshing the gear-wheel T of the shell, as has been described.

The finger-rods R before referred to, are parallel and in the same horizontal plane,

roo

IIC

and each is provided with a pinion-wheel B both of which mesh an intermediate gearthe pocket of the watch-pinion carrier A and being polished by the polishing-disk D in position therefor, and the so-projecting partof each-finger-rod has a finger (4 Figs: 8 and 9,

radially projecting therefrom and in position as the rod rotates to work against a leaf of the watch-pinion, and thus to turn said pinion so as to present another of its leaves to its polishing-disk, said polishing-disk at this time being lifted out of its operating position by theoperation of the mechanism before described, and so as to allow the watchpinion to be turned by the operation of the finger-rod thereon,as described. As before stated, the finger-rods R are supported upon an arm Q and in addition to this support each rod has asupport by its pinion-wheel 13 upon the intermediate meshing gear-wheel C and a further support at their portion toward the watch-pinion carrier .of pocketwheel A in a block E Figs. 8 and 10, one for each finger-rod, but both carried in a stationary common yoke .or frame F", and each arranged in said frame to be adjusted with set-screws G both vertically and laterally and in each direction against a spiral spring H Figs. 8 and 10, confined end to end between the block E and the inside of the carrying frame or yoke F common to both of them. This arrangement of the supportingblocks E for the finger-rods R in a common holder or frame I, as just above described, .is for the purpose of enabling each finger-rod to be adjusted in posit-ion, so as to properly adapt its finger to thework it has to perform in the turning of the watch-pinion being polished and for presenting another of its-leaves to the polishing-wheel. Each pocket D of the pocket-wheel or watch-pinion carrier A is provided with a holder for holding a watch-pinion. This holder, Figs. at and 8, is composed of a block if, havinga shouldered stem (Z entered into and resting upon aspiral spring f? of a radial socket g of the pocketwheel A and of two rests k each secured by aset-screw k passing through a slot Z of its bottom piece m and screwing into said block b andadapted by its upright piece n as a bearing and support for the arbor of the watch-pinion and to be adjusted to and from each other for watch-pinions of varying lengthsof leaves.

A machine constructed of the several parts, and said parts arranged together, as has been described, .when properly adjusted, and the necessary parts properly connected with the driving-power employed, operates as follows: The pocket-wheel A has its pockets one after another and as they come into position provided with watch-pinions by the attendant, and being intermittently rotated, as described, presents at one and the same time the watchpinions in two of its pockets to the polishingdisks D, a watch-pinion to each disk. Each watch-pinionso presented has the edge a of a polishing-disk D, continuously rotated and vibrated forward and backward, entered into and between two of its leaves, Fig. 8, and thus all the surfaces of said leaves of each pinion which are in contact with said edge a of the rotating disks are polished for the whole length of said surfaces. While this polishing is going on the pocket-wheel A is as has been before described.

stationary, but the cam-wheel Z and dog-carrying shell M are continuously rotated, as also the finger-rods R for turning the watchpinions being polished, and the camwheel causes a lift of the polishing-disks from their operative polishing position each time aprojection or toe r of the cam-wheel passes under the lifting-lever of the hinged arm H of the polishing-disks, so that at such time, by the rotation of the finger-rods R the watch-pinions can be turnedaround, presenting another leaf thereof to the action of the polishing-disks when they next drop into operative position as the toe of the cam-wheel which lifted them, acting through the lifting-lever X and carrying-arm II of said polishing-disks, leaves said lifting-lever. This operation continues until the several leaves of the two pinions being polished (the pinions having an equal number of leaves) have been presented to the action of the polishing-disks, when, by the action of the dogs K P carried by the rotating shell M the finger-rods R are lifted from the watch-pinions and the actuating-pawl g of the pocket-wheel is caused to rotate the pocket-wheel, bringing another pair of watch-pinions and in the next two pockets of said wheel into position for being then polished, the polishing-disks being lifted to permit of this rotation of the-pocket-wheel by the action of the toe of the cam-wheel Z, The two watchpinions now presented have their leaves polished by the polishing-disks, followed by the presentation of the remaining leaves thereof, one after another, and the same as before described, and when completed another pair of watch-pinions is presented to the polishing-disks, as before, and so on.

The cam-wheel Z, particularly illustrated, has seven toes orprojections 7, thus producing seven separate lifts of the polishing-disks for each complete rotation of said cam-wheel, and were the dog-carrying shell M which and cam-wheel Z are under continuous rotation, geared with said cam-wheel, so as to run at the same speed therewith, there would then be a movement of the watch-pinion carrier or pocket-wheel A in the direction to present a pairof watch-pinions to the polishing-disks on each complete rotation of the cam-wheel, and thus the machine would be.

ing shell must complete its rotation as the cam-wheel is working by its cam projections or toes 'r for the eighth time instead of the seventh, as before. This, in substance, is true of any number of leaves of the watchpinions up or down from the number of camoperative projections or toes of the camwheel-that is, for a nine-leaf watch-pinion these cam projections must operate nine times for one complete rotation of the do -I six then the cam -wheel should operate six H times for one complete rotation of the dog- 10 carrying shell. These changes of the rotaltionjof the dog-carrying shell in relation to the operation of the projections or toes of the cam-shell are secured by the use of a gearwheel X of suitable size as compared with the other gear-wheels V Z which are of the same size as that of the gears T U attached to the shell and to the cam-wheel -shaft N to secure the reduction or increase,

as'the case may be, necessary in the rate of rotation of the dog-carrying shell as compared with the rate of rotation of the cam-wheel,

andwhich, in the organization of the machine herein described, is always the same. For

i the purpose of this change the gear-wh eel X can be made so as to be readily attached to and detached from the gear-wheel V which rotates with it, or the two gear-wheels may be in one piece or in two pieces rigidly secured together and the change made by substituting another with the proper size of gear-wheel X In order on any substitution of any size of gear-wheel X that the proper meshing of it and of its carrying gear-wheel V and of the intermediate gear-Wheel Z of the train of gearing shall be made, the axial stud Z of the intermediate gear-Wheel Z is carried by an arm J which is hung upon the worm or driving shaft N carrying the cam-wheel as a center, and said arm is adapted to be fastened, after the adjustment of said intermediate gear to its proper meshing position, so as to retain said intermediate gear in such operating position. This fastening, as shown, consists of a shouldered set-screw K passing through a circular slot L concentric with the axis of the shaft N upon which the armJ is hung to turn as a center and screwing into the end upright C of the table 13, and on the outside of this upright the train of gearing described is located.

The forward-and-baclm'ard movement of the polishing-disks described while under rotation obviously brings them into contact with the full length of the leaves of the watch-pinions being polished.

" While the machine described is polishing a. pair of watch-pinions in one pair of the pockets of the pocketrwheel the attendant has all the time necessary to supply the next pair of pockets of said Wheel with watch-pim 'ions for presentation to the polishing disks.

actuating-pawl g and its action on the indexwheel should be shortened, so that on each throw thereof to move said carrier through only one-half the distance in which it is moved when a'pair of polishing-disks are used, as has been described.

By substituting cutting-wheels for polishing wheels or disks D the machiiie described can be made capable of cutting the leaves of watch-pinions from suitable blanks presented thereto, the same as has been described for the presentation of watch-pinions to the polishing-disks, all as is obvious without further explanation.

In Figs. 1 and 2 is shown a turning-tool A,

suitably located forturning the edges of the polishing-disks D from time to time, as their condition from Wear may require. This turning-too1 is attached to a holder 13*, arranged upon a block or carrier C to be adjusted, as may be desired, toward and away from and across the polishing-disks, so as to place it into or out of working position on either disk.

The arrangement and application of turning-tool described form no part of this invention, and are only shown and referred to so as to exhibit the machine described in a complete working form. I V

The suspension, 'Fig. 10, of the finger-rod E in laterally and vertically adjustable blocks E which are backed by springs H in each of said directions, enables the rod by turning the screws G to be adjusted, as may be desired or necessary, to bring the operating-finger of each in proper relation to the leaves of the watcl1pinion which it is to turn in the combined operation of the machine, as has been described, and to secure the necessary length of turn of the pinionas, for illustration, a pinion of a given diameter and having seven leaves requires to be turned each time a greater distance than a pinion of the same diameter but having eight or more leaves, and so on, and in the former case the finger of thefinger-rod must be brought nearer to the axis of rotation of the pinlon than in the latter cases, and vice versa.

Each holder for a pinion, in its application to a pocket I) of the wheel A herein described, is capable of yielding to pressure upon the pinion carried by it in the operation of the polishing-disk D, while at the same time it. is practically held to the action of the disk-an important feature of construction, as is obvious.

It will be observed from the description given of the present improved machine for IIO polished or cut out of and another pinion in I position to be polished or out.

The several arrangements described of the parts of this machine are most effieient ways for securing the results aimed at; but it is not intended to limit the inventimi to said particular arrangements of. said parts, nor any special arrangements thereof, for this invention as to them consists in the combination, with suitable mechanisms to secure the necessary and required operations, and particularly stated, of the pinion polisher or cutter, pinion-rotator, and pinion-holder, of a mechanism to make a connection between the operative mechanisms to lift and lower the pinion polisher or cutter, and to actuate and lift and lower the pinion-rotate]- and the operative mechanism for the pinionholder, by means of which the movements of the pinion-holder to remove apinion from and to place a pinion in the machine can be made to occur when the pinion being removed has had all of its leaves presented for being polished or cut, and whatever may be the number of leaves in the pinion being removed as compared with the number of separate lifts and falls of the pinion polisher or cutter and pinion-rotator during one complete rotation of the driving or operating shaft therefor in the present machine, and the worm driving-shaft N Having thus described my in vention, what I claim,and desire to secure by Letters Patent, 1s-
