LIBANUS M. TODD AND JOHN J. LEARY, OF ROCHESTER, NElV YORK,

ASSIGNORS TO PLACE.-

THE LOEVVER SOLE-ROUNDER COMPANY, OF SAME SPECIFICATION forming part of Letters Patent No. 558,004, dated April 7, 1896. Application filed December 5, 1895. Serial No. 571,169. (No model.)

T 00% whom it may concern.-

Be it known that we, LIBANUS M. TODD and JOHN J. LEARY, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Sole-Rounding Machines, of which the following is a specification.

This invention relates to an improved stockgage for use upon sole-rounding machines of the class which work upon block-stock, and more especially upon machines of this class known as rotaryknife machines in which the block-stock is turned in accordance with a pattern and shaped by the action of the rotary knives.

The improvement as illustrated in the accompanying drawings is designed more especially for use upon the Loewer sole-rounding machine, Patent No. 502,421, dated August 1, 1893. In this machine the pattern and blockstock to be out are held between clamps to revolve on a swinging frame and upon the same axis. Adjacent thereto is a rotary shaft carrying cutter-knives and a guide-roller, the operation being performed by the rotation of the pattern upon the guide-roller, wherebythe swinging frame is moved to change the position of the stock with relation to the cutter-knives.

Block-stock, for the sake economy, is usually cut to asize but little larger than the sole which it is intended to form therefrom, and for this reason it is necessary that the stock shall be positioned in the machine with great exactness. Hitherto it has been usual to employ a stock-gage which was adjustable according to the pattern after the latter had been placed in the machine, and while such stock-gages have been more or less satisfactory in operation so far as the positioning of the stock was concerned they rendered the operation of positioning slow to accomplish. The present object is to provide a stock-gage which may be adjusted with reference to the pattern, but without contact therewith, and according to a scale which may be readily followed,whereby the adjustment may be effected very quickly and the speed of operation thus greatly increased. In carrying out the invention it is preferred to follow a system which involves providing the patterns with holes, at which they are fastened in the ma chine, positioned in accordance with a scale corresponding with a scale or scales upon the stock-gage, all as will be fully described later on.

The drawings show the improved stockgage in two forms, the main points of difference being that one employs gage-adjusting mechanism operated by swinging levers and the other gage-adjusting mechanism operated by turning levers or screws.

In the drawings, Figure l is a front elevation of a sole-rounding machine of the Loewer type with the improved stock-gage of the firstsaid form applied thereto; Fig. 2, an enlarged section taken on line 2 of Fig. 1 and viewed in the direction of the arrow; Fig. 3, an enlarged section taken. on line 3 of Fig. 1 and viewed in the direction of the arrow; Fig. 4, an enlarged broken section of a patternclamp; Fig. 5, a plan section taken on line 5 of Fig. 3; Fig. 6, a sectional view showing a detail of the construction, the section being taken on line 6 of Fig. 7; Fig. 7, a broken section taken on line 7 of Fig. 6; Fig. 8, a broken section of a rod forming a detail of the construction and marked with .a scale; Fig. 9, a plan view of a sole-pattern; Fig. 10, a View in elevation of the improved stoclc gage of the second said form; Fig. 11, an enlarged broken section taken 011 line 11 of Fig. Fig. 12, a plan section taken on line 12 of Fig. 10; Fig. 13, an enlarged section taken on line 13 of Fig. 12; Figs. 14: and 15, en-

larged and brokensections taken, respectively, on-lines 14 and 15 of Fig. 10; Fig. 16, a plan section taken on line 16 of Fig. 10, and Fig. 17 an enlarged broken elevation of one side of the detail shown in Fig. 16.

As the improvement in either form is mounted upon the vibrating carriage or swinging frame of the machine only that much of the machine is illustrated in the drawings, for the reason that the construction and operation of the rotary cutters and other parts are well known in the art.

A is a part of the main frame of the machine, and B the vibrating carrier or swing- I00 turning of a hand-wheel .90.

ing frame, pivotally mounted at its lower end upon a shaft t. Journaled in the frame B is a shaft comprising sections O, O, and O 011 the outer end of the section O is a drive-wheel s, which may be an elliptoid, as shown in the aforesaid Loewer patent, and upon the inner end of the same section is the member a" of a pattern-clamp D. The shaft-section 0 slides longitudinally in its bearings and is provided at one end with the member 0" of the clamp D and at its opposite end with the member (1 of a stock-clamp E. The shaft-section O is provided at its inner end with the member q of the clamp D and is adapted to be moved longitudinally in its bearing by the The members of the clamp D are provided with smooth flat clamping-faces, and on the member 0" are pins 1- 1- which occupy a certain predetermined position and enter sockets 0' 0- in the memher 1'. On the shaft-section C is a suitable spring 19, which tends to press the member 7' against the member 0.

Referring first to the construction of the stock-gage shown in Figs. 1 to 8, inclusive, on the frame B, in the position shown, is a boss or bracket n, from which extends a bar a, which may be square in cross-section, as shown. Fitting and sliding upon the bar 41 is a sleeve m, forming a part of the supporting-frame of the stockgage F. Fastened upon the frame B, toward the upper end of the latter, is a segmental bar or yoke Z Pivoted at its lower end to a bracket Z on the frame B is a lever m, pivotally connected between its ends at m to the sleeve m and at its upper end sliding along the segmental bar I. On the lever m at the bar Z is a bracket 171 which extends over the bar Z and is provided with a clamp-screw m, which may be turned to engage the barl and hold the lever m in adjusted position. \Vhile a clampscrew in is shown for fastening the lever m against movement upon the bar I, any other suitable fastening means may be employed. On the sleeve on, and forming an integral part thereof, is a sleeve m extending at right angles to the sleeve m and provided through it with an opening an. Integral with the sleeve m is a sectoral plate m provided with a segmental slot m in the arc of a circle of which the sleeve-opening m is the center. Extending through the opening hi is a bar 7;. Fixed to the bar It, above the sleeve m is a collar and also fixed to the bar 70, below the sleeve of, is a sleeve k carrying an arm k Pivotal] y mounted in the outer end portion of the arm is a catch is, and at the peripheral edge of the plate m on the under side thereof, is a flange m provided with notches m on in the positions indicated in Fig. 1. The collar 70 and sleeve 70 prevent longitudinal movement of the bar 70 in the sleeve m but permit it to be rotated between the two positions wherein the catch k engages the notches m m. On the upper end of the bar 70 is an arm 7& and at the lower end thereof is an arm 70 which extends parallel with the arm k Fastened at its upper and lower ends, respectively, in the arms 70 k is a guide-rod 70 which extends parallel with the bar 7c and passes through the segmental opening m in the plate m and through an opening in the arm 70 On the lower end portion of the bar 70 is an arm i, having a sleeve portion i, which surrounds and slides upon the bar 75, a sleeve portion 75 which surrounds and slides upon the guide-rod 7t, and an upward-extending finger portion Adjustably secured to the finger i is a lower gage member or gage-plate i having a downward-extending finger i which is attached to the finger by means of a clamp-screw i. The gage-plate 2' may be raised and lowered with reference to the arm i by loosening the clamp-screw i and may be fastened in adjusted position by tightening the set-screw. At the sleeve 11 is a yoke i provided with openings to receive the bar 7; on opposite sides of the sleeve and slide with the said sleeve upon the bar. Sliding upon the bar 7c above the armiis an arm h, having a sleeve portion 7b, which surrounds the bar 70, a sleeve portion 7L2, which slides upon the guide-rod 70 and an upward-extendin g finger 7L3, bent to a right angle at its upper end portion. Adjustable upon the finger 7b3 is a gage member or middle stock-gage 7L4, mounted upon a finger 7L5, secured to the finger 77, by means of a thumb-screw h. The finger 71 may be slid longitudinally upon the finger [L3 to a limited extent and fastened in adjusted position by means of the thumb-screw h. At the sleeve portion 71/ of the arm h is a yoke h having openings through it to receive and slide upon the bar 7s at opposite sides of and with the said sleeve. Above the plate m is an arm g, having a sleeve portion g, which surrounds and slides upon the bar 7o, a sleeve portion 9 which fits around and slides upon the guide-rod 70 and abent finger 9 Mounted upon the finger g is a gage member or upper stock-gage 9 having an arm or finger g, which is adjustably secured to the finger g by means of a thumb-screw g. The finger g may be slid to a limited extent upon the finger and fastened in. adjustable position by means of the thumb-screw g. At the sleeve portion gis a yoke gZhaving openings through it to receive and slide upon the bar 7; on opposite sides of and with the said sleeve. Fulcrumed at 1 upon the stationary sleeve on is a lever f, connected at its long arm, through the medium of a link f, with the yoke 2' A linkg connects the lever f, between the link f and fulcrum y, with the yoke 7L7. The link f is in two overlapping parts, which slid e upon each other and are held together by means of a screw f thus rendering it possible to shorten or elongate the lever, as desired. A link f connects the short arm of the lever f with the yoke The link f is also constructed. to be lengthened and shortened, as desired, it being formed of overlapping sections held together by a screw f In the sole-roundin g machine shown in Fig. 1 of the drawings the member 1' of the pattern-clamp D and the member q of the stockclamp E are in rigid relation and extend in the same plane. When the machine is started, it rotates the member 'I' of the pattern-clamp one complete revolution and then stops, and the driving mechanism is so arranged that the member 0", its companion member r, and the stock-clamp will always stop at a certain fixed position, in which position the pins r are at a slight angle to the vertical plane. The patterns Z employed in the machine are preferably, though not necessarily, of sheet metal and provided with openings 2 a, which, as it is preferred to provide them, are located in the ball and heel portions, as shown in Fig. 9. The openings 2 a register exactly with the pins 0*, and while the location of the said pins may be changed, if desired, it is necessary that each pattern used with the machine shall have openings 2 .2 which conform exactly in location with the pins. The pattern is placed in position in the machine before the stock Y is inserted, and this is accomplished by moving the clamp member 9' to the right in Fig. 1 against the resistance of the spring 19 to permit the placing of the pattern upon the pins 0' The clamp is closed by the resilience of the spring 19, whereby the pattern is held firmly between the members 1' r. The stock Y, known as block-stock, and previously cut to a shape more or less nearly approximating that of the pattern, is placed in position by opening the clamp E, which is done by turning the wheel 00 in one direction, and fastened in place by turning the wheel 00 in the opposite direction. The pressure exerted by the clamp member q against the stock and through the latter against the I clamp member q and clamp D holds the parts firmly together,whereby in the rotation of the drive-wheel 8 they will all turn together. As before stated, it is necessary that in placing the stock in the clamp E it shall be so positioned with relation to the pattern that the rotary cutters may act more or less upon the entire edge portion of each blank or individual piece of block-stock.

I11 practicing our invention we prefer to follow a certainsystem, which maybe brie fly described as follows:

The machine, it will be understood, is capable of operating upon both insoles and outsoles of all sizes and shapes. Having established a standard for the position of the pins 7' according to two, or perhaps three, widelyvarying sizes, which standard will be preferably common to all machines, each pattern Z will be provided with holes 5 .2", which will register exactly with the pins. It may be stated that in practice the upper pin 1- in Fig. 4, which is the pin intended to be engaged by the openings 5 of all the patterns,

will always be provided at a certain fixed distance from the center of rotation of the shaftsections 0 C. For patterns of large size, such as those for mens shoes, a clamp D would be provided, having the lower pin 0" as far or farther from the center of rotation of the shaft-sections than the upper pin 1*. For the patterns of small-sized soles, as for childrens shoes, the lower pin r may be near the center of rotation of the shaft-sections O C. In practice not more than two or three difierent clamps D need be provided for a machine, the larger patterns used having holes 2 z to fit the pins of the larger clamp and the smaller patterns having holes 2 a to fit the pins of the smaller clamp.

The stock-clamp E should be of a size, especially when working upon insoles, nearly approximating the size of the pattern, in order that it may hold the stock as nearly as convenient to the edge portion of the latter while itis being operated upon by the cutters. In practice one clamp E will do, especially when the machine is working upon flexible insoles, for but a limited number of sizes, both with relation to length and width.

It is necessary in positioning the stock in the clamp E provided that the stock shall project more or less from all sides of the clamp and be in such position in the clamp that in its movement in accordance with the pattern the cutters will cut more or less from all sides of the stock and the clamp will never come into contact with the knives. For this reason it is desirablein practice to provide the holes z z of patterns Z of different sizes atdifferent distances from the inner edge, which is the edge 22 of the pattern, the holes being each at an equal distance from the farthest projecting portions of the said inner edge at the ball and heel port-ions of the pattern. In other words, the holes 2 2 should be equidistant from the dotted straight line shown in Fig. 9. In practicing the said system the holes 2 z of each pattern are punched at equal distances from the inner edge of the pattern, varying, as may be desirable, according to the width and shape of the pattern, by stages of one-sixteenth of an inch, and 011 each pattern the distance is marked, as shown at the top of the pattern in Fig. 9, where the numeral XIV indicates that the holes .2 z are fourteen-sixteenths of an inch from the inner edge. The pattern Z is so placed in the clamp D that the inner edge .2 is toward the operator or front of the machine. On the segmental bar Z is a scale Z marked with numerals indicating sixteenths of an inch, and the lever m carries a pointer m which in the movement of the lever registers with the scale. Thus according to the numeral marked thereon the lever m may be swung to move the stock-gage frame toward or away from the vertical plane of the center of rotation of the shaft-sections C G,

and therefore toward and away from the plane of the pins 4*.

In positioning the stock in the clamp E it is located with relation to three points of the pattern-namely, the point at the lowest part of the heel-seat, the point 2' or farthest projecting inner edge portion of the heel-seat, and the point a or farthest projecting part of the inner edge of the ball portion. The lower gage member i is intended to position the lower end of the stock with relation to the point 2 of the pattern, the middle gage member h" to position the stock with relation to the point a of the pattern, and the gage member g to position the stock with relation to the point a of the pattern, a slight allowance in practice being provided for at all three said points to cause the cutters to work upon the material at those parts. The three gage members i 71 g are upon sliding supports, as before described, all of which connect, by means of the links described with the lever f, and their link connections are such that the member i will be moved a greater distance in the movement of the lever than either the member h or g.

In practice the patterns for soles of different sizes will vary in length to a much greater degree than they will in the matter of the distances between the points Z3 2 which mark the points of farthest protuberance at the end and inner edge of the heel-seat, and the parts of the gage are so connected with the lever that the movement of the gage members will approximate the variations of the three points 2 a Z5 in the different sizes and shapes. Pivotally connected at its lower end to the pin i on the yoke t is a rod e, which passes upward loosely through a plate or bracket e on the sleeve m On the said plate or bracket is a finger e presenting two shoulders e and 6 respectively, affording pointers. Marked upon the rod 6 is a scale c indicating sizes, and the gage members are so mounted with relation to the lever f and scale (2 that when the rod is moved by the action of the lever to register at, say, the line marked 1 in Fig. 8 with the pointer e the gage members will be in position to conform to the points 2 2 Z5 in accordance with the pattern of a No. 1 outsole. By raising the lever until the figure 1 on the scale 6 registers with the pointer e the gage members will be in position to position the stock in conformity to the points 5 .2 .2 of the pattern for a No. l insole.

As is well known in the art, two separate sets or series of the same numbers are generally employed to designate the sizes of lasts, one relating to childrens shoes and the other to those of adults, and the rod 6 and segmental bar Z would be provided, preferably, with two scales conforming to the two series mentioned.

In operation when soles of a certain size are to be rounded the operator selects the pattern, noting at the same time the figure at the top, before mentioned. His first operation will be to move the lever m, if necessary, to cause the pointer on to register with the proper numeral 011 the scale Z corresponding with the said numeral on the pattern. The lever on may be then secured in adjusted position by turning the thumb-screw m. The operator will then move the lever f until the proper number in the scale 6 on the rode registers with the pointer on the finger c If he is to cut insoles, he will select the pointer 6 and if he is to cut outsoles he will select the pointer 6 When the parts are thus adjusted, they maybe fastened against displacement by tightening a thumb-screw g in the sleeve portion g which is adapted to engage the rod 75'. The adjustment may be effected while the latch is in engagement with the notch m and the frame consisting of the rod 70, arms h "i g, and gages carried thereby is swung out of the way. After the adjustment the said frame is swung to the position wherein the latch engages the notch m as shown in Fig. 1, which places the gage members in the proper location to position the stock. The stock is placed in the clamp E and caused to rest at its heel portion upon the gage member 2 and hear at its inner edge portion against the gage members 7L4 g hen the stock is positioned, the stock-clamp is first closed and the gagecarrying frame then swung out of the way. The stock is thus in position to be operated upon by the rotary cutters in the usual manner.

In case that for any reason the block-stock from which soles are to be formed shall have a materially different shape from the pattern-as, for example, a materially greater concavity or sweep at the shank than the pattern-it may be desirable to position the stock in the stock-clamp with due allowance for such variations. This may also be the case when, as it sometimes happens, the stock is to be cut full or lar er than the pattern. Any such variation from standard requirements may be effected in this improved stock-gage and still cause the gage members to be properly positioned by movement of the levers m f with reference to the scales by adjusting the fingers which carry the gage members on their supports, as before described, to withdraw one or another of the gage members to the desired extent from the position it would occupy under standard requirements.

If desired, the supporting-finger for each gage-carryin g finger may be suitably marked, as at y y in Fig. 2, to indicate the positions that the ends of the latter should occupy with reference to the former under standard requirements.

In the construction shown in Figs. 10 to 16, inclusive, (1 is a sleeve adapted to fit and slide upon the preferably-squared bar or shaft or, before mentioned, and which forms the solesupport of the gage-frame. The sleeve d at its outer end portion is formed into a yoke 01, having a threaded opening (1 in its outer end to receive a threaded rod 0, provided with a handle 0 The inner end of the rod 0 is reduced, as shown at c in Fig. 14, and there IIO enters a socket d in the end of the bar n. The reduced portion 0 is provided with a circumferential recess 0 which is crossed by a pin 0 extending through the bar 71. Thus the rod 0 may rotate in the socket 61 but is held to the bar by the pin 0 Rotation of the rod 0 by means of its handle 0 will move the sleeve cl upon the said bar and a gage c is provided upon the bar, as shown in Fig. 12, for a purpose hereinafter described. Integral with or in fixed relation to the sleeve d and extending at right angles thereto is a sleeve (1, provided through it with a smootly-bored opening Extending through the opening d and confined therein to rotate freely, but without longitudinal play, is a rod or shaft 1), provided alongits lower end portion with sore w-threads Z) of one pitch, between the threads I) and sleeve (Z with a screw-thread b of another pitch, and above the sleeve (Z with a screwthread I) of still another pitch. The thread or threads I) extend in one direction and the threads b b in the opposite direction, and in practice it is preferred to provide a screw b with a lead of about six threads to the inch, a screw 12 with a lead of about nine threads to the inch, and a screw 19 with a lead of about twenty-five threads to the inch.

Pivotally mounted upon the upper and lower end portions of the shaft 1) are parallel arms Z2 b respectively, to which is secured at opposite ends a guide-rod 17, extending parallel with the shaft 1). On the upper end of the shaft 1) and fixed thereto is a crank Z2 provided in its free end portion with a catch in the form of a spring-controlled pin b provided at its upper end with a handle 12 and tapered at its lower end b to engage a socket h in the upper end of the rod 1), as shown in Fig. 11. The arm a, carrying the lower gage member a, has a threaded opening through it to travel upon the screw b and is bored in proper location to slide upon the rod 1). The arm aicarrying the middle gage mem ber a has a threaded opening through it to receive and travel upon the screw b and the arm a, carrying the upper gage member a has a threaded opening through it to receive and travel upon the screw 12 The arms a a are provided with openings to receive and move upon the rod Marked upon the rod 1), preferably at the arm a, is a gage 6 and the arm a may carry insole and outsole pointers I), as shown in Fig. 10. Fixed upon or formed integral with the sleeve d is a plate (1, having a segmental upward-extending flange (1*, provided on its upper edge at one end portion witha spring-catch d Integral with the arm 11 is a laterally-projecting finger I), which rides .upon the upper edge of the flange C1 and when moved toward the position shown in Figs. 16 and 17 depresses the spring-catch 01 When it reaches the position shown in those figures, it passes the spring-catch d and bears against a stop d, the end of the spring presenting a shoulder which holds the finger against movement. The spring (i is provided with a projecting lip c1 at which it may be engaged by the operator and depressed to permit the finger I) to he slid across it.

The bearings of the arms a a a at the screw-shaft B are split and may be compressed by means of the screws 3 (shown in Fig. 10) to compensate for wear. The sleeve (1- may also be split, as indicated in Fig. 12, and compressed by means of screws y to fit snugly upon the bar n. These split bearings being a common expedient in mechanics, it is not thought necessary to illustrate them more fully or describe them more minutely. The lower gage member a is provided on its under side with an internally-threaded sleevepiece a, at which it is screwed upon the arm a, whereby it may be raised and lowered to adjust it with relation to the latter. WVhen adjusted, it may be secured by means of a jam-nut a The plate forming the lower gage a is preferably squared, so that it may be adjusted by quarter-revolutions upon the arm a. The gage members a 6 21113 provided at their edges with threaded supporting pins or bolts a which pass through openings in the arms a a. On each pin or bolt a on the inner side of the respective arm, is a jam-nut a and on the outer side of the arm is a thumb-nut a By loosening the nuts the gage members may be adjusted .toward or away from their supporting-arms and fastened in adjusted position by means of the nuts a, a

In operation the frame, consisting of the sleeve d and parts carried thereby, may be positioned in accordance with the numeral on the pattern Z, as before described, by turning the crank o with relation to the gage c, the crank c and threaded rod 0 being the equivalent in this respect of the lever m and segmental bar Z of the other construction. To position the gage members in accordance with the pattern, the handle 19 may be grasped and raised to withdraw the pin b from the socket b and the crank b turned to rotate the screw-shaft b in accordance with the gage 19 which corresponds with the gage e in the other construction. The turning of the screwshaft 2) in one direction causes the lower and middle gage members to be lowered the predetermined relative distances and the upper gage member to be raised a predetermined relative distance. The bearing-sleeve d and the screw-shaft b are in practice at an angle to the vertical plane the same as the bearing-sleeve m and attendant parts in the other construction, whereby the tendency of the frame, consisting of the screw-shaft, arms 1)" b rod b, gage members, and their supporting-arms, is to swing away from the stockengaging position. In moving the frame to the stock engaging position the finger Z) slides upon the segmental flange b until it passes and is engaged by the spring (1 whereby the parts are locked in the stock-engaging position. Before the machine can be started to turn the stock against the rotary cutters the said frame must be swung out of the way of the rotating stock, and this may be accom plished by simply depressing the spring (i to release the finger Z), when the frame will swing by gravity out of the path of the stock. In the Loewer sole-rounding machine automatically-operating means are provided for moving the stock-gage out of the path of the stock when the machine is started, and, if desired, mechanism for the same purpose may be provided for releasing the stock-gage in the present constructions whereby it will move out of the way.

The main object which it is desired to accomplish in both the constructions shown and described is to afford means whereby the gage members may be quickly, readily, and accurately positioned without contacting with the pattern, to the end of effecting materially greater economy in the matter of the time required for the positioning operation and greater certainty under all conditions than has been possible in the use of stock-gages hitherto provided. The difference between the two constructions is purely mechanical, and, broadly considered, their operations are substantially the same. In minor particulars each construction may be said to have advantages in certain respects over the other. For example, in the construction first described the levers f m may be moved approximately as quickly to effect a change of several numbers as a change of one number in the sizes of soles to be successively rounded, while in the construction last described one complete rotation of the screw-shaft b will effect a change of but one number, and the same may be said of the screw 0. On the other hand, the construction last described possesses advantages over the construction first described, because when cutting soles commencing with, say, the largest size and then adjustin the machine by gradations for smaller sizes in regular rotation a single complete turn of the operating-crank will change the adjustment one size, and the operator need not refer to the scale each time the pattern is changed.

In practice, to change the gage members from one size pattern to another involves usually the movement of the lower gage memberone-sixth of an inch, the upper gage mem her one twenty-fifth of an inch, and the middle gage member only one-ninth of an inch in the direction of movement of the lower gage member. Thus while a material change is effected in the relative positions of the upper and lower gage members the middle gage member moves but slightly with relation to the lower gage member. The movement of the upper gage member being but about one twenty-fifth of an inch with each operation in the construction shown, it is not necessary in practice that it should be moved with each adjustment of the lower gage members, but

only occasionally, as once for every two or more changes in the sizes of the patterns. For this reason, and because it is difficult to provide durable threads as fine as required at the screw b the upper gage member may have separate independent adjusting means instead of the fine screw b which adjusting means may in practice be operated to move the upper gage member only occasionally, as required. It is within the scope of this invention, therefore, to have three or more gage members, of which only two or more shall be independently and simultaneously movable to unequal distances.

Vhile the mechanisms shown and described carry out the invention in a manner that is eminently satisfactory, the constructions are susceptible of modifications in the matter of details without departing from the spirit of the invention as defined by the claims.
