page_text: We PETER JACOB JANNS and FRIEDRICH FERDINAND STROBEHN both of Schulter-
blatt 21 Altona in the Empire of Germany, Manufacturers do hereby declare the
nature of this invention and in what manner, the same is to be performed to be
particularly described and ascertained in and by the following statement:-
The object of this invention is to join in a more efficient and convenient manner the
upper and lower parts of an ordinary two part last intended for holding in form a
boot or shoe.
In the accompanying drawing, Fig. 1 represents a side view and Fig. 2 a plan of
the improved last which consists of the lower or principal part A and of the upper
part B, the latter being so connected to the former that it may be loosened at any time
therefrom, and taken out and inserted again and fixed whilst the last is within
the boot.
Fig. 3 is a longitudinal section. Fig. 4 a cross section on line x Fig. 3.
Fig. 5 shows in section the upper about to be completely removed from the lower part
shown in Fig. 6 in elevation and in Fig. 8 in plan. Fig. 7 is a cross section of the
part B on line y y Fig. 3.
The fastening between B and A has been usually done heretofore by means of a
wooden screw inserted through B into A in the direction of the arrow n (Fig. 1) said
screw being screwed in or taken out when the last is in place through the leg of the
boot. Such screws soon however become inefficient after use and do not then resist
the blows and knocks to which the last is exposed in the manufacture of the boot
or shoe.
The improved fastening comprises a bolt s. screwed or driven into the lower part A
as shown.
This bolts. projects above the upper surface of A as shown in Figs. 3, 4 and 6 and
has at the upper end a T head revolvably fixed thereon so as to be turned by a key
or suitable tool whilst therefore the bolt s remains fixed, the head or cross piece r can
be turned upon the end of the bolt either into the position of Fig. 3 or into that of
Fig. 6.

This head is of oval or oblong or like shape in plan. Along the under side of the
upper part B is cut a slit p. of a width as seen in Figs. 2 and 7 to correspond with
the narrowest width of the head r. When the head r is alligned with the longi-
tudinal direction of the last (Fig. 8) then the part B can be slid over the head r onto
the part A into the position shown in Fig. 1.
At the rear end, the passage p is widened above in the horizontal plane of the
head so that the latter may be turned crosswise and rest over the solid portions
being continuations of the side walls of the slot p. and so hold the part B firmly upon
the part A and prevent withdrawal of the part B. In order to reach the head r
with the key, an open pit is made in B above the end of the slot p. If the
seat for the cross head is to be of metal, a metal lining i may be made to fit into
the pit being provided with a bottom and a slit or cutting therein corresponding
to the narrower width of the cross head in order that it may be passed over the
head when the latter is. alligned with the longitudinal direction of the last.
The above described fastening, has besides its durability, the additional advantages
over the screw fastenings used heretofore, that the loosening or fixing of the two
parts of the last is done by less than a single turn of the head r, whilst heretofore,
a long wooden screw had to be screwed in and loosened again.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In lasts which consist of upper and lower separable parts the combination of a
bolts in the lower part and a cross head thereon with a slot p in the upper part
widened to receive the cross head for fastening substantially in the manner described.
