To all whom it may concern;

Be it known that we, EDMUND NEWBERRY and JOHN WILLIAM SHARP, subjects of the; Queen of Great Britain, and residents of Ket- 5 tering, in the county of Northampton, England, have invented certain new and useful Improvements in Iron Lasts, (for which we have obtained patents in Great Britain, No. 464, dated January 12, 1886, and No. 4,896,

dated April 2, 1887,) of which the following is a full, clear, and exact specification.

This invention has for its object improvements in and appertaining to lasts used in the manufacture of boots and shoes, and relates to improvements on our former English patof adjusting the instep, and our present im- 2' 5 provements also relate to improvements therer;

on, and in conjunction with lasts having detachable heel-blocks or other parts.

According to our invention the bolt which serves to lock the heel-block to the last is continued through the said last to a point immediately underneath the instep, and to effect this the last is hollowed out. The loose instep, which is hinged toward the toe, is suitably shaped, and at the instep end is pro- 3 5 vided with a pivoted rod, which extends downward in the cavity or hollow of the foot portion of the last. This rod, in addition to its pivot, is connected to the instep by a spring, which serves to keep the rod vertical when 0 in position, and to allow of the same being capable of being moved simultaneously with the releasing of the sliding bolt. The rod is provided with an adjustable collar, which rests upon a step or projection on the last,.

thereof serves at the same time to push the instep-rod from its position on the step, and

In the specification of the aforesaid patent we set forth and illustrated a method so release both the heel and the instep and 5.0

allow of the ready withdrawal of the last from the boot.

In the drawings, Figure 1 is aside elevation. Fig. 2 is a plan view; Figs. 3 and 4, a partseotional and elevational views. Figs. 5 and 6 are modified forms in-section. Figs. 7 and 8 are a part plan and side elevation.

' Similar letters ofreference refer to like parts in all the figures.

A is the last. 6o

B is the detachable heel-piece.

O is the controllable instep, hinged to the. last at D. To this controllable instep is pivoted at a the rod a, which is connected to the instep before referred to by the spring I). It is upon this rod that the collar 0 is attached, and it is free to slide up and down the said rod a in order to determine the height of the instep. In the loose heel-piece there is an opening E cored out in order to allow of the insertion of a lever serving to operate on the end of the locking-bolt F, which passes through the last A, as will be seen more clearly by reference to Fig. 3. On the end of this sliding bolt is a wire rod F, the end of which enters a hole parallel to that in which the bolt F slid'es. This part F not only prevents the bolt from turning, but serves to retain the part F. In Fig. 3 the bolt F is shown in its normal position assumed by the application of the spring F, as shown in Fig. 3. Immediately 011 depressing the lever and operating on the end of the rod F the opposite end F serves to actuate the rod (t and its collar 0, and releases it from its 8 5 position on the step d, by which movement the said rod a assumes the position shown at Fig. 4. By this movement of the instep the heel-piece is simultaneously detached and the last readily removed from the boot. It will be seen that owing to the curve of the parts G and H, referred to in our former specification, the said parts are as readily released and as readily and securely locked.

In Fig. 5 we have shown a modification of the horizontal bolt. In this example the instep is connected to the last by a flexible hinge at D. It may be, as shown, by means or catch has been described.

of springs, or in some cases it may be by a loose connection. In this example we have shown the rod a'with'the collar 0 secured to the said rod in any desired position by means of a set-screw. In thisexample the bolt F is at the last end provided with a head F, which serves to prevent the bolt from entering too far into the heel portion B. This bolt is retained in its normal position by a fiat spring F instead of by a coil-spring, as shown in; the previous examples. In this modification we have shown the heel portion provided with a wearing-piece, (marked B',) secured to the said heel portion by a screw or other suitable device. This wearing-piece may be of steel or other suitable metal, and may be provided with a slot-in order that it may be set up to the bolt and properly adjusted' In this figure we have shown the lever I for disconnecting the parts A and B. It will be obvious that this locking-bolt, instead of passing through the portion of the last, may be attached to the heel portion, and in Fig. 6 we have shown a modification of the same. Instead of the opening for the insertion of the lever being provided in the heel portion, we find it advantageous that the said space should be in the last. The bolt F, on the insertion of a suitable lever, is disconnected from the part A and simultaneouslyit has been found that this movement of the lever may serve to operate upon the sliding bolt F for effecting the release of the instep, as described, with reference to the previous figures.

YVe are aware that it is not new to divide a last by arranging a detachable heel for the purposes which are well known, such lasts having been divided in a similar manner at the commencement of the present century, and in which the hinged locking connection However, we would have it understood that to this we lay no claim.

In Figs. 7 and 8, instead of supporting the instep by a bar with collar resting on a step, the instep-bar rests on top of sliding bar which looks the heel portion. In this sliding bar is a recess, into which the instep bar drops when the locking-bar is forced back by the lever, so that at same timethat heel is released to take boot from the last the instep also subsides, thus taking the strain from that part of boot and allowing it to be easily taken off without a wrinkle. The pressure of the spring causes bolt to grip the instepbar against side of hole in which it stands, being held in that position till withdrawn from boot and heel placed in position, when by raising the instep the bolt shoots into the heel and makes the last firm and solid;

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In divided lasts, the combination, with the heel-piece, of a hinged or loose instep provided with an adjustable step actuated simultaneously with the discon uection of the heelpiece and the step-actuating mechanism, as shown and described.

2. In divided lasts provided with an adjustable instep, the combination-of the lock- -ing-bolt F in theheel portion B and the releasing-bolt in the foot portion, operated upon simultaneously and substantially in the manner hereinbefore described and set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 6th day of January, 1888.
