LAST.

SPECIFICATION forming part of Letters Patent No. 583,138, dated May 25, 1897. Application filed March 30, 1896. Serial No. 585,468. (No model.) Patented in England January 12, 1 1 N 79 To an whom, it may concern.-

Be it known that I, THOMAS BRINING, a subject of the Queen of Great Britain, residing at 36 Sussex Street, Richmond Hill, Leeds, in the county of York, England, have invented new and useful Improvements in or Relating to Lasts for Use in the Manufacture of Boots or Shoes, (for which I have obtained a patent in Great Britain, No. 795, hearing date January 12, 1895,) of which the following is a specification. I

This invention relates to improvements in that class of lasts for use in the manufacture of boots and shoes in which the heel and toe pieces are divided. Hitherto many attempts have been made, with more or less success, to secure the separate parts of a so-divided last firmly together, so that when the said parts are put together and placed within the boot or shoe they will be rigid and even for hammering, lasting, and other purposes. Great difficulty has also been experienced either in securing or locking the parts together or in releasing them when placed inside of the boot or shoe, pokers or other releasing-tools having to be employed for separating the parts, thereby pnllin g the boot or shoe out of form.

Now the object of the present invention is to construct a divided last so as to be easily and firmly put together yet readily released and its parts removed from the boot or shoe without stretching or displacing the uper and without usin a poker or releasing. 6

tool.

The present invention may be applied to a wood last; and it consists, essentially, in combining one or more dovetails and single or double interlocking catches 0r hooks with a last divided at such an angle that in separating and releasing, say, the toe portion from the heel part the former is caused to slide toward the heelthat is,within its total length thereby preventing the stretching of the upper, a spring pin vor bolt (hereinafter termed ,a spring-pin being employed for the purpose of preventing the two parts from sliding apart.

In the drawings hereunto annexed, Figure 1 is a part sectional elevation of a wood last with this invention applied; Fig. 2, a plan of same, looking at the top; Fig. 3, a part plan of the same, looking at the bottom. Figs. 4, 5, and 6 are respectively a part sectional elevation, an end elevation, and a plan, looking at the top of the toe portion of the interlock ing arrangement for a wood last. Figs. 7, 8, and 9 are respectively a sectional elevation, a plan, and an end elevation, of the heel portion of the interlocking arrangement for a wood last. Figs. 10, 11, and 12 are respectively a side and end elevation and a plan of the spring-pin.

A is the toe part of the last, and B its heel portion.

J J are the castings, which are respectively fixed to the toe and heel portions A and B. The castings J J are preferably, though not necessarily so, made semicircular or nearly so, as shown at Figs. 6 and 9, although, owing to the angle at which they are fixed, they appear in an elliptical form at Fig. 3. The casting J is armed with a horizontal projecting piece J which fits onto the top of the last, as shown at Fig. 1. The horizontal projecting piece J 2 is armed on its upper surface with an end or thrusting piece J between which and the boss J X the last or pivot stand K (shown in dotted lines at Fig. 1) is passed to the hole I. Through the boss J X is formed the vertical hole E, in which the spring-pin F works for preventing the toe and heel portions sliding apart. In the casting J is cast the dovetail recess D, (which has V sides in cross-section, as shown at Fig. 3,) into which fits the dovetail projection D of casting J. A pin 0 is arranged on the casting J to project beyond its upper end, as shown, and to fit into the cap or hood 0 formed for its reception on the casting J. A projection J preferably semicircular in cross-section, is also provided on the casting J, which fits in a corresponding recess J in the casting. J, and they are employed for aiding in preventing any lateral movement of the two portions A and B, while the dovetail D and pin 0, which enters the cap C prevent any endwise movement of the said parts.

A pin F, encircled by a helical spring F, (these two parts being hereinafter termed the spring pin or bolt F) is passed into the vertical hole E, so that its end will pass into the portion of the vertical hole E located in the heel portion B. The spring pin or bolt F is arranged to project beyond the top of the last, as shown, and its opposite end may be withdrawn from engagement with the heel portion B by any convenient arrangement or devicesuch as, for instance, say, by a knob or head or by a cord passed through it or by means of the device shown in the drawings, in which the spring-pin F is armed at its upper end with the projection G and so arranged that its under surface 9 acts upon a cam-path a, cast, cut, or otherwise formed in or on the toeportion casting J. The projection G is passed through the hole H, east or formed in the toeportion casting J and which is made to communicate with the vertical hole E. Then the projection G is passed through the hole II and turned at a right angle thereto, it performs the double function of first preventing the spring-pin F working out of position, and, secondly, of withdrawing the said spring-pin from its engagement with the heel portion B when pulled or rotated on the eainpath w.

I is a hole formed in the last for the reception of the last stand or pivot.

To fix the castings J and J in position in the last, I proceed as follows: Before the last is divided into the two parts A and B along the line x x I bore a hole L at the required angle, into which is placed the barrel portions of the castings J and J. The two said castin gs are then secured in position by the screws M, which pass through the horizontal projecting piece J into the top of toe portion A, the casting J being held temporarily in position by cement, glue, or the like. The last is then sawed or otherwise divided into the two portions A and B along the line a: x, after which the castings J and J are secured, respectively, in position by the screws N and O. The heel portion B and its casting J are held in position by the spring-pin 1 as already described.

To remove the divided last from the boot or shoe, the spring-pin F is first withdrawn, as hereinbefore described, from its engagement with the heel portion B, and as soon as the heel part of the lasted boot or shoe is raised the two portions A and B of the last will readily and easily slide apart without stretching the upper and without using a poker or releasing-tool for separating the two parts of the last.

In the case of a wooden last with a soleplate the sole-plate may be cast or attached by any suitable means to the hereinbeforementioned castings J and J.

Having now particularly described and ascertained the nature of the said invention, what I desire to secure by Letters Patent is In a boot and shoe last substantially such as herein described and illustrated, the combination of the toe-piece A and heel B divided in an angular direction substantially as shown, the castings J J fixed respectivelyin recesses in the toe-piece A and heel-piece B, said casting J being armed with a horizontal projection J which fits on the top of the toepiece A, a vertical thrusting-piece J and a boss J X both arranged on the projecting piece J a longitudinal recess J 5 formed in the casting J, a recess formed in the cap or hood C of the casting J, and a dovetail recess D formed at the base of the casting, the said casting J being armed with the projecting pin 0, a longitudinal barrel portion J adapted to fit the said recess J and a projecting piece I) adapted to fit and engage with the said recess D, the vertical hole E, the spring locking-pin l armed with a wing G, working in hole E, and a cam a formed in the said boss J on which the said wing G slides, all arranged substantially as herein set forth.

In testimony whereof I have hereunto signed my name to this specification in presence of two subscribing witnesses.

THOMAS BRINILTG.
