Description
UNITED-STATES WILLIAM P.IBEERS, OF NEWARK, NEW JERSEY.
IMPROVEMENT IN LASTBLOCK FASTENINGS.
Speciiication forming part of Letters Patent No. 186,97*?, dated February, 1877; application filed July 17, 1876.
i ing the features of the new improvement.
The lastA and block B are the same as those in common use; but the improvement is in the mode employed for holding them together when the last is being worked.
In the upper side of last, near the heel, where the block begins, I cut a groove, C, and across the front of this groove I attach a metal plate, a. This plate has a notch in it, opening from the rear. into which the shank of the screw eis made to slip, and the sides of the headfof the screw slide under the plate a. This screwpasses through the rear end of the block and through the plate D, made East to it, and above this plate on the screw is a nut, f. Thus, in connecting the last to the block, when the nut is turned up the block is slid into position on the plane Gr, when the screw-head slides in to the groove O and under the plate a, and when in position the nut f is screwed down and the two parts are lirmly locked together; and, of course, to take out a block it is only necessary to loosen the nut, and it may be at once drawn out.
The shank of the screw is made flat or square, so that it will lit into the notch of the plate a, and not turn around when the nut is being` turned.
With these simple devices I readily secure the block to the last, and avoid piercing and tearing the block and last with a nail driven in to hold them together, and which sometimes splits the blockalways mars it. Therefore,
What I claim as my invention, and desire to secure by Letters Patent, is-
ln combination with the last .A provided with the `groove C and plate a, the instepblock B, provided with plate D, screw e, and uut f, all substantially as shown, and for the purpose set forth.
WILLIAM P. BEERS.
