I ADJUSTING DEVICE FOR SOLEI-LEVELING MACHINES.

SPECIFICATION forming part of Letters Patent No. 555,547, dated March 3, 1896.

A plication filed. November 21, 1894. Serial No. 529,496. (No model.)

To all whom it may concern.-

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States, and a resident of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Adjusting Devices for Sole-Leveling Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates generally to devices of the above class, and more particularly to such devices adapted to be used in connection with machines in which the operation of leveling is performed by a vibrating roll and auxiliary mechanism, my invention being especially adapted to vibrating-roll machines wholly or partially automatic in their operation.

My invention consists of mechanism connecting the device for adjusting the jack for different lengths of shoe with the jack-oscillating mechanism, whereby an adjustment of the jack for a shoe of any length efiects'a suitable adjustment of the jack-oscillating mechanism.

The object of my invention is to increase the efficiency of this class of machines by simplifying their adjustment and rendering the same partially independent of the skill and judgment of the operator.

The accompanying'drawings illustrate my invention as applied to the machine shown and described in Letters Patent of the United States, No. 540,223, dated May 28, 1895, and issued to Erastus E. Winkley and Benjamin Phillips for improvements in sole-leveling machines; but my invention may be applied to other machines of a similar nature and to analogous machines for finishing the bottom of a shoe-sole, and I do not wish to limit the same to any specific adaptation.

In the drawings, Figure 1 is a side view of a device embodying my present invention, showing immediately-associated parts of the Winkley-Phillips machine,to which reference is made above. Fig. 2 is a front view of same.

Similar letters of reference refer to similar parts throughout both views, and similar figures of reference refer to similar parts throughout both views herewith submitted and both views of the drawings of said patent, the parts of the XVinkley and Phillips machine shown herein being designated by the same reference letters and figures by which the same are designated in said patent.

As shown in the VVinkley-Phillips patent above referred to, the jacks D D are mounted upon the sleeves 55 55, turning loosely on the shaft 47, and are arranged to be locked to an interposed sleeve 54, also mounted upon the shaft 47, and arranged to be rocked with or independently of said shaft by the dependent arm 48, which is connected by the connecting rod 49 with a cam-actuated lever 50. A circular adjustment-way S1 is provided in the arm 48, by means of which the point of connection of rod 49 may be transferred toward or away from the rocking or oscillating center, and the length of oscillation of sleeve 54 and of a connected sleeve 55 andjhe jack D mounted thereon may be varied to properly present a long or short shoe to the levelingroll.

In the machine shown and described in the Winkley-Phillips patent when the sleeve 55 .is locked to the sleeve 54 by means of the locking mechanism therein shown, the jack D mounted thereon stands in an approximately horizontal position, while when the sleeve 5 is disengaged the jack D rests in an inclined position on a rest 65. To engage the jack D with the oscillating mechanism the operator raises the jack D until it is in an approximately horizontal position, when the sleeves are locked by a sliding spring-pressed pin 58 in the tubular rod 57. The pawls 68 63 are pivotally mounted on sleeve 54 and are operated to unlock the jacks from the oscillating mechanism, as shown in said patent.

Each of the jacks D D, so far as any description thereof is necessary herein, consists of toe-support Z) and a heel-support a, one of which is movable along the bed-plate n to adjust the jack for a long or short shoe. As shown in the drawings, the heel-support a is movable and the toe-rest b is stationary. The

movement of the heel-support a may be eonveniently effected by a thread-bolt c rotated by a hand-lever (I, the bolt 0 having suitable bearings in the bed 91 and extending through a threaded lug on the heel support, which is mounted on suitable longitudinal ways on the bed 02.

In my present invention, as illustrated in the drawings, I mount upon the sleeve 54: a pair of sliding rods E E, provided with suitable bearings in cross-barse c, secured to the arm 48, in which they are free to reciprocate and by which they are guided during their reciprocation. The rods E E are connected by a lateral rod 0 and reciprocate together, being so connected by the rod 0 that raising or lowering one effects a corresponding motion of the other.

The lever 40 is extended beyond the arm 48 and provided with a slot 7L through which extends the rod 0, the arrangement being such that when the rods E E are raised or lowered the lever 40 is moved along the adjustmentway 81 and the length of the oscillation of the j ack varied.

It is of course understood that the lever 49 issecured to arm 48 by a connection free to slide along the adjustment-way 81.

On each of the heel-supports a a is a laterally-projecting shoulder r. The shoulders r r are preferably placed on adjacent sides of the heel-supports a a.

The upper ends of the rods E E are similarly bent forward and downward and project beyond and vertically over the shoulders r r, the arrangement being such that when both jacks D D are in the same relative angular position and both shoulders r r at the same distance from the center of oscillation of the jack each of the rods E E will be in contact with the shoulder 0'.

It is evident from the foregoing description that when both jacks D D are disengaged the rods E E will rest 011 one or the other of the shoulders '7' r, resting on the shoulder r farther away from the center, and it is also evident that raising either of jacks D D to connect it with the oscillating mechanism will raise both the rods, which are arranged to reciprocate together, a distance which will vary proportionately with the distance from the center of oscillation of the shoulder 7', and that the connecting-rod 49 will be raised a corresponding distance along the adjustment-way 81.

It is evident that the oscillation of either jack D with the sleeve 54 will not effect any reciprocation of the rods E E, since said rods are mounted thereon and also oscillated therewith, so that the relative position of the j aeks and rods is not altered.

It will be further noted that when one jack D is in engagement and the rods E E supported thereby the other jack D, which is disengaged, rests upon the rest and the shoulder 4' thereon is out of the way of the rods E E until the other jack D is disengaged, when the rods E E fall and rest upon the shoulder r farther from the center on either jack.

To prevent the rods E E from being raised during the oscillation of the jack D an d throwing the machine out of adjustment, I have found it convenient to provide the following: Each of the rods E E near the bend therein is provided with a series of notches p, which are engaged by a pawl t pivotally mounted on sleeve 54:, preferably on tubular rod 57. The pawls i i are also pivoted to the pawls 63 63 at a point above their fulcrum, the arrange= mcnt being such that while sliding pins 58 are in engagement to lock sleeves 54 and 55 together the pawl tis held in engagement with one of the notches 1) and the rods E E held firmly by the pawl t and shoulder r and can neither be raised or lowered; but when the pins 58 are thrown out of engagement by the pawls (33 the same movement of the pawls 63 releases the pawls it and leaves the rods E E free to be raised by raising either of jacks DD.

I have in this specification briefly described the form and functions of the associated parts of the \Vinkley-Ihillips machine, in so far as a description thereof is necessary to enable a person skilled in the art to understand the nature and operation of my present invention, and all of said associated parts not do scribed herein will be found fully illustrated and described in said Letters Patent, and in view of the same further description thereof herein is deemed unnecessary.

The operation of my present invention is described as follows: The operator places the spindle of the heel-support a in the spindlehole of the last and by turning the lever d moves the heel-support along the bed 12 until the toe of the last is in position on the toerest I). The jack D is then raised to engage with the oscillating mechanism, and by means of the shoulder 1' the rods E E are raised, raising the connecting-rod 49 along the ad justment-way 81. As soon as the jack is engaged, the pawls t i engage with the notches p and further raising of the rods E E prevent the rods E E being held in position by the pawls it and the shoulder r. \Vhen the rods E E are in the position just described the connecting-rod 4:9 is at the position on the arm 48, which gives the required length of oscillation for the jack to present the last for which it is adjusted to the roll. \Vhen the jack D is disengaged from the oscillating mechanism the jack and rods E E fall together, carrying the rod 49 to the bottom of the adjustmentway 81 and leaving the rods E E in position to be raised by either jack, as hereinbefore described.

I wish to say that I do not consider my invention limited to the mechanism shown and described; but

I claim, broadly, and desire to secure by Lettors Patent of the United States- Witness my hand, in the presence of two subscribing Witnesses, this 7th day of Novem- 1o ber, A. D. 1894.
