Letters Patent No. 84,647, dated December 1,1868: I

rMPRovnn LAST-BLOCK nLEvAToR AND INsTP-s'rnn'rcnnn The Schedule :referred to in these Letters Patent and making part of the same.

To all whom it may conce/m.-

Be it known that I, SEELYE RICHMOND, of Annapolis, in the county of Anne Arundel, and State of Maryland, have invented a new and improvedLast-Block Elevator and Instep-Stretcher combined; and I do hereby declare the following to be a full and correct description of the same, suflicient to enable others skilled inthe art to which my invention appertains, to fully understand and use the same, reference being had to the accom panying drawings, which make part of this specica tion, and in whichc Figure 1 is a perspective view of my invention;

Figure 2 is a longitudinal section of the same when used. as a last-block;

Figure 3 is a similar view of the'same whenusedas an instep-stretcher; and

Figure -4 is a detachedview of the screw-socket.

Like letters of reference indicate like parts in the several figures. l

The nature of my invention consists in providing the last-block, on its under side, with a recess, in which a nut plays freely, through which nuta short screw passes, and, seizing in the last, elevates or lowers the lastblock to the size of the instep of the boot or shoe to be made.

Also, inthe provision of asmall screw, bearing against which a long screw rests, when, passing through the last-block and nut, the block is to be used as an instepstretcher.

A, in g. 2 ofthe drawings, represents the last, provided with the customary last-block B, on the near end of which, on its under side, is formed a slot, b, being narrow at its rear, and wider at Vits ont end.

' This slot is covered -by a plate, c, having an opening,

` d, through which, and the hole ein the top of the lastblock B, a screw, C, passes, on which, in the slot b, a nut, D, plays.

This nut has bevelled edges, the front part of it catching and being held in the rear and narrow part F, and forms a bearing for the long screw G when the y device is used for an instep-stretcher.

The operation of my device is very simple and easily understood.

When used as shown in g. 2, as a last-block Aelevater, the short screw, G, screwing into the nut F, forces the last-block B either down or up, according to the size desired, by means of lnut D in slot b, and holds the last-block B rmly in that position, while, when the device is used, as .shown in g. 3, as an instepstretcher, the long screw, G, elevates the block B, by means o f nut D, resting against the bearing H, which is screwed into nut F.

When it is not necessary to elevate the last-block at all, the device shown in iig. 2 holds the last-block se curely on the last. y

Having thus described my invention,

What I claim as new, anddesire to secure byLetters Patent, isz- 1. The inelining slot b, in the rear part of the lastblock B, in combination with the nut D, substantially as and for the purpose set forth.

'2. The combination of the'slot b, nut D, short screw C, and nut F, when operating as a last-block elevator, substantially as described.

3. The screw-socket H, when constructed as described and shown, and operating in alast, substantially as and for the purpose set forth.

SEELYE RICHMOND.
