i FREDERICK W'. KITTLINGER, OF BROOKLYN, NEW YORK.

LAST.

SPECIFICATION forming part of Letters Patent No. 683,606, dated October 1, 1901.

Application filed February '7, 1901. Serial No. 46,333. (No model.)

T0 all whom, it muy concern:

Beit known that I, FREDERICK W. KITT- LINGER, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Lasts, of which the following is a specification.

The present invention relates to lasts made in separable part-s, and has for its main object the provision of means whereby the parts are firmly locked together against relative motion in use as a last and permitting of the ready separation of said parts whenever it is desired to draw the last out of the shoe or boot.

To this and other ends the invention consists of features of construction, details, arrangements, and combinations of devices hereinafter described, and more particularly pointed out in the appended claims.

The preferred form of the invention is illustratedin the accompanying drawings, forming part Aof this specification, in which- Figure 1 is a side elevation, partly in section along the central vertical plane of the last, of a last in which the invention is embodied; and Fig. 2 is a plan, partly in scction, of the same.

In the drawings the reference-letter a indicates a sole or lower section, and b an upper or instep section, of the last, the upper surface of section a aud the lower surface of section fitting againsteach other, as shown. The section a, is provided with a vertical centrallylocated longitudinal slot c, so placed as to be covered by section b. Immediately in rear of and overhanging or overlying part of slot c is a keeper, which is conveniently formed of a button d, whose shank is driven into the section a. This button d is preferably rounded on top and by preference is beveled or undercut underneath for a purpose presently to appear. The keeper may be fiush with or project above the surface at the top side of the section a, or it may be otherwise arranged or constructed. The section b is slotted for a distance along its central vertical longitudinal plane, as indicated ate, and is recessed atfto receive or fit over the button d. The recess .f is also extended upwardly into section b for a purpose presently to appear. The slots c fe lie in the same planein. the assembled last. A catch g lits in section b in slot c, being held in place by a pivot-pin h. The working end i of the catch is so located that its dat working face X engages with the bevel or undercut edge of the keeper, surface against surface. A spring la is placed in recess f behind the catch g and presses the catch into engagement with the button or keeper, as above set forth. The catch g is prolonged above the pivot h and is shaped to coact with the bottom of the slot e for the purpose of retaining the end z' in position to coact with the rounded-off top of the button d, which presses the catch toward the toe of the last as the parts are assembled, the catch ultimately snapping under the button or keeper as the section b moves into place upon section a.

The section b may be held against motion forwardly and transversely of the last by any suitable means-as, for example, the means shown in the drawings. Thus the front end of the section b may be so held-by forming it with a V shape at Z, iitting under an undercut counterpart on the section a, while the catch g and slot c or the recess fand button d, or both, may be used to prevent lateral motion of the rear end of section b. The described last forms a rigid structure over .are avoided. By pressing on the catch g at a point above the pivot 7a it may be moved backward, thus moving the working end t' toward the toe of the last and disengaging it from the keeper, after which the section b may be removed from the boot or shoe by an upward and backward pull on the section. Section a may be withdrawn thereafter in the usual manner.

It is preferable that all parts of catch g except end li be wholly within the section h. In such a case the section b is provided with a transverse perforation m just in rear of the front edge of the catch g-that is, the catch g projects so far into the hole m, which crosses slot e, that the hook usually employed by workmen for drawing out lasts when it is inserted in hole m engages with the front edge of the catch g and moves the end i forwardly or toward the toe of the last so far as to disengage it from under the keeper, after which an upward and rearward pull on the hook draws out the section b, or the hook may so move the end 'L' that some force will still be required to disengage the end i from the keeper as the section b is drawn ont, or the .catch may be wholly disengaged from the keeper by the hook and the Walls of the re'- cess f t down about the button closely, so that section b must be lifted somewhat as it is Withdrawn from the shoe or boot, so as to pass over the button, or the button may be ush with the surface of the top side of the section a, and in such case the catch and slot c do the Work of preventing lateral motion of the rear of section b.

The invention may be embodied in forms other than that illustrated in the drawings and above described Without departing from the spirit of my invention. I do not therefore limit my claims to the precise form of the invention shown in the drawings and above described.

Vihat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination of a sole-section ct, an instep-section b, a rounded-off circular button d secured to and projecting above the top side of the section a, said section ct having a recess or slot c forward of and below the button d, a recess in section b adapted to t closely around the button d, a catch g pivoted to section b and adapted to enter slot c and engage under the button CZ, and a spring in said recess in section b for actuating the catch g, substantially as described.

2. Inv a last, the combination of sole and instep sections ct b, a rounded top button d on .and projecting above the top side of section ct, said section n', having a slot forward of and under the button, a catch g in a slot in section b and having a working end t' projecting below section b, a pin connecting catch g and section b and said section b having a recess which fits closely over the button d, a spring in said recess behind the catch and acting thereon, a transverse perforation in the section b into which the upper end of catch g projects, and means for preventing the forward end of section b from moving laterally, substantially as described. Signed at-New York city, in the county of New York and State of New York, this 6th day of February, A. D. 1901.
