JACK FOR SHOE-MACHINES.
SPECIFICATION forming part of Letters Patent No. 579,205, dated March 23, 1897.
Application filed June 15, 1896. Serial No. 595,666- (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 Jacks for Shoe-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention relates to shoe-supporting jacks for shoe-machines, such as sole-laying machines, and more especially to those shoesupporting jacks having provision for correlatively adjusting the heel and toe supporting I 5 standards thereof.
The object of the present invention is to produce a shoe-supporting jack in which the correlative adjustment of the toe and heel supporting standards to accommodate a large or small last can be quickly and easily accomplished; and to this end my invention consists of such devices and combinations of devices as will be fully hereinafter described and claimed.
My invention is illustrated in the accompanying drawings, in which Figure l is a side View of a jack embodying the same. Fig. 2 is a top plan view of the same. Fig. 3 is a front view of the toe supporting standard and base removed from the bed, and Fig. iis atop plan view of the bed.
Similar letters of reference refer to similar parts throughout the several views.
A represents the bed of the jack, provided upon each side with the undercut or dovetail guides a, in which are adapted to slide and be adjusted the carriages B and C of the heel and toe supporting standards r and 'r.
The carriages I3 and C, as shown, are provided with beveled or dovetail edges 1) and c, which fit into and are guided in their movements by the guides or upon the bed A.
The heel and toe standards may be of any usual and well-known construction and provided with any preferred form of last-supporting devices.
In sole-laying machines embodying a former having a projected shank portion, which forms and shapes the shank of the shoe on the jack, it is necessary that the shank portion of the shoe be positioned in line with the projected shank of the former, whether the shoe under operation be a large one or a small one, and that the correlative adjustment of the heel and toe supporting standards shall be from a point closely approximating the center of the projected shank of the former.
The correlative adjustment of the heel and toe supporting standards is secured by the following mechanism: Extending from the base of carriage B is a rack b, which may be formed integrally therewith or suitably secured thereto. To the bed A is secured a similar rack f, which lies in a parallel line with the line of movement of rack Z7. Can riage C on its end nearest the carriage B is provided with upwardly-extending lugs h, in which are formed bearings for shaft cl, the said shaft being freely rotatable in said bearings. Secured to shaft 01 are the gears 19 and f which, respectively, mesh with racks b and f, the construction being such that a movement of either carriage in one direction will causea correlative movement of the other carriage in the opposite direction. The relative sizes of gears b and f is preferably such that the toe-supporting standard is moved about twice the distance the heel-supporting standard is moved in the same time, whereby the correlative adjustment of the standards is obtained and the desired relative position of the projected shank portion of the sole-laying form and the shank of the last, whether the last be long or short, is secured.
Any convenient means may be employed for locking the toe and heel standard in this adjusted position, the construction shown being well adapted for such purpose.
As shown, the locking device comprises a lever 25, pivoted to the side of the carriage C 0 by means of the shaft 25, fitted in bearings u on said carriage.
The lower end of said lever carries a latch '6 which is adapted to take into the rack 61 formed upon one side of the bed A.
If desired, a hood m may be secured in positionto cover and protect gears 12 and f the said hood being secured to the lugs h by screws Z, which pass through apertures in ears Z, formed on said hood.
The operation of the invention is as follows: As shown in Fig. 1 of the drawings,
the standards 0 and r are in their extreme extended position and capable of receiving on the spindle 0 and toe-rest 0' a last of the largest size. When it is desired to adjust the jack for a smaller last, the latch 15 is released from the rack 23 and the toe-carriage O and its attachments are moved toward the heel-carriage B, such movement causing the gear in mesh with the stationary rack f, to rotate, and thus to rotate the gear 11 fast on said shaft, in the same direction. Gear Z) engages rack b on the carriage B and draws it toward the carriage 0, thus causing a corresponding movement of the carriage B toward the carriage C, the correlative movement of the carriages B and 0 being as before described.
Having fully described my invention and its mode of operation, what I claim as novel, and desire to secure byLetters Patent of the United States, is
1. The combination with the movable carriages, carrying the toe and heel supporting standards, of the movable and stationary racks, and gear connections between said racks and one of said carriages, substantially as described.
2. The combination with the movable carriages, carrying the toe and heel supporting standards, of a movable rack on one of said carriages and a fixed rack on the bed, and gear connections between said racks and the other carriage, whereby a movement of one carriage will produce a correlative movement of the other carriage, substantially as described.
3. The combination with the movable carriages, of a fixed and a movable rack, with the relatively large and small gears mounted on one carriage and meshing with said racks, substantially as described.
In testimony whereof I have hereunto set my hand, in the presence of two attesting witnesses, this 10th day of June, A. D. 1896.
ERASTUS E. WVINKLEY.
