HINGED LAST.

SPEGKFEGATION forming part of Letters Patent No. 699,785, dated May 13,- 1902.

Application filed April 9, 1900. Serial No. 12,171.' (No model.)

To all 'whom it wwf/J concern: 1

Be it known that I, JONATHAN T. BROWN, a citizen of the United States, residing at Marblehead, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Hinged Lasts, of which the following is a specification.

This invention has relation to sectional lasts in which the two sections are hinged together to permit the heel portion to be thrown up at an angle to the fore part to permit the easy insertion of the last into or its withdrawal from the shoe.

The object of the present invention is to provide a hinged last which may be employed practically throughout the entire process of constructing a shoe and which shall be capable of withstanding the various strains to which it is subjected during the process of leveling, heeling, and slugging.

To these ends the invention consists of a last possessing certain features of improvement, which are clearly illustrated upon the drawings, described in the following specifications, and particularly pointed out in the claims hereunto appended.

Referring to the said drawings, Figure l represents a last embodying my invention. Fig.2 represents a longitudinal section through the same, the toe end of the fore part being omitted for lack of space. Fig. 3 represents a similar' section and shows the two parts of the last at an angle to each other with the lock withdrawn by a suitable tool. Fig. 4 represents a view looking at the top of the last. Fig. 5 represents a section on the line 5 5 of Fig. 2. Fig. 6 represents asimilar view with the lock drawn to an inoperative position. Fig. 7 represents a view looking at the end of the fore part with the two members of the hinge separated. spective view of the hinge detached. Fig. 9 represents a perspective view of the hinged member to which the fore part is secured. Figs. l0, 1l, and l2 represent a different embodiment of the invention.

On said drawings the fore part is indicated at a and the heel part at Z). Their meeting ends are provided with engaging faces ct/ b', and with diverging faces c2 b2, the planes of which intersect each other at the axis of the Fig. S represents a per-v pintle which unites the members of the hinge together. The hinge members are Secured, respectively, to the toe part and the heel part,

which are cut away or recessed to receive them. The fore or toe part is provided with two separate cylindrical apertures a3 awhich are substantially parallel to each other and which, as illustrated, are in lines Substantially perpendicular to the plane of the face a'. The 6o fore part is likewise provided with the groove a5, communicating with the apertures a3 a4. The hinge member which is connected to the fore part is indicated at c and consists of a substantially flat plate having projected from one edge two cylindrical pins c c2, which are of a size to enable them to fit snugly in the apertures a3 a4. Said pins are secured rigidly in place by similar pins or other fastening devices d d' passed transversely through the 7o fore part of the last. The hinge member which is secured in the heel part b consists of a heelplate c', which covers the entire bottom surface of the heel part, a boss c2, depending from the heel-plate, a tubular bushing c3, pro- The forward edges ot the webs c4 e4 project 85 into the groove d5 of the fore part, while the hinge member c is provided with the rearwardly-projecting end c3, which extends well into the groove which separates the webs c4 c,

The said end c3 constitutes a portion ot' the 9o locking mechanism which holds the fore part and the heel part securely in the positions illustrated in Figs. l and 2 and forms, as it were, a iinger adaped to be engaged between a stationary abutment or member and a movable locking member, as will subsequently be described. The member c is likewise pro-- vided with a second linger c4, which projects at substantially a right angle to the finger c3,

and itextends into a groove in the heel-plate c, roo

as illustrated in Figs. 2 and 8, and its rear edge bears firmly against the heel-plate when The plate or hinge member 8o the heel part is thrown downward in the position shown in Fig. 2.

The heel-plate is of course recessed or cut away to receive the rear hinge member, and it will be noted by an examination of Figs. 2 and 3 that the tubular bushing e3 projects from the top of the heel part a short distance, this being for apurpose to be subsequently described.

In the boss e2 is formed a slot e5, which is substantially parallel to the face of the heel seat or plate, and said slot communicates with the interior of the hollow bushing e3 by a hole or aperture e6. In the slot is placed a movable locking member, which consists of a slide g, held normally forward in locking position by a compression-spring h, having one end inserted in a socket in said slide and having its other end connected to a screw-pin 71,', projecting from the inner face of the heel-plate. The said slide or locking memberis provided with the central aperture, one wall of which is inclined, as indicated at g', and said aperture lies in line with the hole c, so that by inserting a tool consisting of a pin through the hollow bearing and the hole e6 to bring the end of the pin against the inclined wall g pressure against said pin will cause the withdrawal of the locking member into inoperative position. The movable locking member Coacts with the finger c3, being so located that when the heel part is in the position shown in Fig. l or in Fig. 2 relatively to the fore part the locking member will be sprung forward to overlap the upper edge of the linger and prevent the heel part from being swung about the pintle f relatively to the fore part.

In order to stiifen the last and prevent too great strain upon the pintlc f, an abutment or stationary member j is employed and is located in the path ot' the finger c3. The abutment consists of a stud j, passed through Ithe webs c4, and it is so placed as to be engaged when the faces a' b of the parts a b meet, the said finger being ot' a diameter equal to the distance between the abutmentj and the movable lock g. A

The finger c4 engages the heel plate simultaneously with the engagement of the abutment by the finger c3, so that the entire strain to which the last is subjected in leveling is borne principally by the hinge.

The overlapping Webs of the hinge furnish a large area of engagement between the hinge members and securely hold the fore part and the heel part against sidewise or torsional movements with relation to each other.

rIhe heel plate is provided with a pocket at the center ot' its surface to receive a plug fn, into which tacks may be driven in attaching an insole to the last. The plugis preferably formed of leather or equivalent material capable of frictionally holding the ends of the tacks which are driven therein.

In Figs. il and 12 a diiierent embodiment of the invention is illustrated, in which the sliding lock fm' is cylindrical and is held from rotation by a screw m projecting into a slot therein. The spring m2 is in a sleeve m3, secured to the hinge member by the said screw m. In this form of the invention I dispense with the finger to engage the heel-plate, although I retain the abutment or stop for the lock-engaging finger.

Having thus explained the nature of the invention and the way of constructing and using the same, without attempting to set forth all the forms in which it may be made or all of the modes of its use, 'I now declare that what I claim isl. A hinged last having a fore part, a heel part, and a hinge connecting said parts, said hinge comprising two members of which one isprovided with a finger or projection and the other is formed with a stationary abutment and a movable lock adapted to receive said linger or projection between them.

2. Ahinged last havingahinge comprising two members secured in the respective parts of the last, and apintle connecting said hinge members, the member for the heel part carrying a sliding lock movable longitudinally of the last, and the member for the fore part having a projection extending rearwardly and adapted to be engaged by the lock.

3. A hinged last having a hinge comprising two members and a pintle, the member for the heel part having two forwardly-projecting webs, and the member for the fore part having a web lying between the first-mentioned webs and pivoted therein by the pintle, the first-mentioned member having a locks movable longitudinally of the last into engagement with the web of the second-men; tioned member.

4L. A hinged last having a hinge comprising two members connected by a pintle, the meniber for the fore part having a rearwardly projecting web, and the member for the heel part having parallel webs to receive the webv of the Erst-mentioned member, said member for the heel part also having a stop to limit the movement of the other member when it has reached the extreme of its movement, and a lock to hold said other member against said stop.

In testimony whereof I have affixed my signature in presence of two witnesses.
