LAST AND SUPPORT FOR THE SAME.

EPECIFEGATION forming part of Letters Patent No. 340,690, dated April 27, 1886.

Application filed June 8, 1885. Serial No. 168,033. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELLERY O. WRIGHT, of Campello, county of Plymouth, and State of Massachusetts, have invented an Improve ment in Lasts and Supports for the Same, of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

In heel-nailing machines the spindle carrying the last-holding pin or pins is made adjustable vertically, in order to enable the bot tom of the last to be maintained at the proper level to insure the cooperation therewith of the pressingand nailing mechanism, and when boots or shoes are to have heels automatically nailed thereon while yet upon the last upon which they were lasted considerable time is lost and difficulty experienced in adjusting the spindle to place the bottom of the last in proper position, such adjustment being necessary owing to variations in the thickness of the cone or heel of the last vertically. The last is provided with one or more vertical holes,

to be entered by the last-holding pin or pins. The object of this invention is to secure the placing ot'the bottom of the last in the same horizontal position, notwithstanding variations in thickness of the cone or heel part, 0 and to secure the proper position with the same last pin without change of its position.

In accordance with the invention herein contained the last-pins upon which the last is placed equal in length the thickness of the 3 5 cone or heel of the thickestlast to be employed, and the last is bored through at its cone or heel in the direction of its vertical thickness, and the bottom of the last is provided with a metallic bottom plate or rest, against which 40 the end or ends of the lastpins will strike to support the last before the cone or heelstrikes the block attached to the lower end of the spindle and containing the last-holding pins. The drawing represents in side elevation a last embodying this invention, the spindle,

block, and pins being shown in elevation.

' The wooden last A, of any desired shape, is

bored vertically through the cone or substance of the heel, and at the bottom of the last, by screws 2 or otherwise, is applied a rest-plate,

B, of metal. The spindle (3 has secured to it the block D, from which extend two pins, 6

e, of greater length than the thickness vertically of the cone or heel of the thickest last to be used, so that the last will always be sup- 5 ported by the pins 0 e acting against the interior of the plate B, rather than by the cone of the last resting directly upon the block D,

as heretofore.

By determining the position of the last by the plate and pins it is possible to always imsure the same level for the bottom of the last, no matter what may be its thickness vertically.

The holes in the last are shown as lined with metal tubes H,which,besides saving wear upon the last, prevent splitting under strain. The tubes might be closed at their inner ends, the pins coming against the closed ends of the tubes, the closed ends thus serving as restplates.

The parts 0, D, and e e are common to the McKay & Bigelow beefing-machines in common use, except as to the length of thepins Vhen the usual leather heel is being at- 7 tached to the sole of the boot or shoe, held on the last A in usual manner, the pressure exerted to drive the nails and to compress the heel solidly is borne by the plate B and the pins resting against it, thus doing away with s the liability of splitting the cone or heel of the last,which frequently occurs when the last itself touches the block D or directly receives the pressure, and by the en'lployment of two pins the last is held from being twisted out of 8 the proper straight line.

It will be noticed that the last does not touch the block I), and that the ends of the pins 6 c, acting against the plate B, take all the pressure, and the wood of the last is not subjected 0 to pressure.

I do not broadly claim the pin and plate B.

I claim" A spindle and attached block having two pins, 6 e, of greater length than the vertical 5 thickness of the cone or heel of the last, combined with a last having two holes to receive the said pins, and having ator near its bottom a metal rest-plate, against which bear the ends of the said pins to determine the position in o of the bottom of the last, the said plate and In testimony whereof Ihavesigned my name pins sustaining the pressure exerted when the i to this specification in the presence of two heel is being applied, the last being supported subscribing witnesses. only by the said pins, the latter preventing ELLERY G. \VRIGHT.
