SPECIFICATION forming part of Letters Patent No. 398,923, dated March 5, 1889.

Application filed November 23, 1888. Serial No. 291,699. (No model.)

To all whom it may concern.-

Be itknown that I, EDWARD O. WooDwARD, ot' Brockton, county of Plymouth, State of Massachusetts, have invented an Improvement in Lasts, of which the following description, in connection with the accompanying drawings, is a specification,like letters on the drawings representing like parts.

The last contained within a boot or shoe when being heeled in usual manner is held in position by a pin or tool entering a pin or tool receiving hole formed in the heel portion of the last. The great pressure exerted upon the last by the machine often acts to split the last, to avoid which a metallic thimble has been placed in the pin or tool receiving hole, and the thimble has had its lower end closed to resist the pressure; but with such thiruble the great pressure against the closed end of the thirnble breaks the same through.

This invention has for its obj ectto provide a strong and durable support or bearing-suri the last intersecting the pin or tool receiving Figure 1 shows in longitudinal section a.

last provided at the base of the pin or tool receiving hole with a bar-1ike support made in accordance with this invention; Fig. 2, a vertical section of the last, taken on the dotted line sow, Fig. 1, and Fig. 3, alongitudinal section of the last provided with a modified form of support at the base of the pin or tool receiving hole.

The last-body ais provided at the heel portion with a pin or tool receiving hole, into which is snugly fitted the metallic tube 22. A hole, as c, is bored or formed in the heel portion of the lastintersecting the pin or tool receiving hole at right angles. A bar-like support, herein represented as a metallic block, (I, having a fiat upper face, is placed in said hole 0, so that the tube Z) bears directly upon the fiat face of the said block. A block of wood or other material, cl, is then fitted into the hole 0 and finished flush with the surface of the last.

Fig. 3 shows a cylindrical support, (1'', in lieu of the fiat-surfaced block in Fig. l. The lower end of the tube b will be cut away to bear directly on this block or bar.

The support herein shown constitutes a rigid as well as an enlarged or laterally-extended bearin g to resist the great or excessive pressure of the pin or tool entering the pin or tool receiving hole, and also resisting pressure which may be brought to bear on the metallic tube.

I claim 1. The last having the pin or tool receiving hole, and having a block-receivin g hole in its body intersecting the said tool-receiving hole, combined with a metallic bar-like supportinserted in the said block-receiving hole at the end of the tool-receiving hole, the said block constituting a rigid bottom within the body of the last for the tool to abut against, substantially as described.

2. The last having the pin or tool receiving hole, and having a blocku'eceiving hole in its body intersecting the said tool-receiving hole, and a metallic tube placed in the said toolreceiving hole, combined with a m etallic barlike support inserted in the said block-receiving hole at the end of the tool-receiving hole, the said block constituting a rigid bottom within the body of the last for the tool to abutagainst, substantially as described.

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

EDYVARD C. WVOODVARD.
