MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY LAST Application led February 13, 1932. j Serial No. 592,725.
This invention relates to separable lasts, that is, to lasts the heel parts of which can be removed from a shoe without disturbance of the forepart.`
The object of the present invention is to provide such a last which shall be strong, practical and cheap to manufacture.
Accordingly, I have provided a last of the type in which collapse and removal of the heel part are accomplished by sliding the heel part upward and forward on the forepart in order to release a hook or hooks mounted in one last part and engaging corresponding pins in the other last part, to hold the parts together.
In accordance with the present invention, such a hook is provided which is strongly resilient, so that it may firmly hold its pin and prevent looseness. As illustrated herein, such a hook is formed on a flat bonding plate whlch is slit through a substantial part of its width adjacent to the hook, to permit the hook to bend at the bottom of the slit.
These and other features of the invention comprising certain combinations and arrangements of parts. will be apparent from the following description of a preferred embodiment of the invention shown in the drawing, 1n which Fig. 1 is a side elevation, broken away to show the bonding mechanism; and
Fig. 2 is a cross-section on theline II--II of Fig. 1.
The illustrated last comprises a forepart 10 and a heel part 12, divided along a substantially straight cut 14. The bonding mechanism comprises a plate 16vand two pins 18, 20. The plate 16 is anchored in a kerf 22 in the forepart 10 bytwo pins 24, 26, and projects backward across the cut 14 into a kerf 29 in the heel part 12. VThe projecting portion of the plate has two hooks 28, 30 on it which, as shown, project upwardly and engage the pins 18, 20, respectively, and thus hold the last parts together. n
The pin 20 is located a little too far back in the heel part to be readily engageable with the hook 30 in its normal position. To permit such engagement the plate 16 is split up about half its width in front of the hook 30,
as shown at 32. This enables the plate` to is slightly overhung at 34 to act as a fricn l tional lock. l
The illustrated last collapses `by throwing the heel part upwardly relatively to the foren part to release the hooks, after'which the heel part is readily removable from a shoe, leavingthe forep'art in place therein. l The last is held in operative position by the overhang at 34 and the friction developed between the hook 30 and pin 20 by the Spring action inthe locality marked 36.
Having described my invention, what I claim as new and desire to secure by Letters Patent of theUnited States is:
1. In a shoe last, a forepart and a heel part, separated by a cut permitting sliding movement of one relatively to the other, and bonding mechanism joining them comprising an abutment on one of said parts and a resilient hook on the other arranged to be engageable with each other when the last parts are in operative position to hold the last parts together, the arrangement being such that the hook is resiliently distorted in engaging the abutment. y
2. In a shoe last, a forepart and a heel part, separated by .a cut permitting sliding movement of one relatively to the other, a
bonding plate lying parallel to the plane of' relative sliding movement and mounted in one of said last part-s, a projecting hook on said plate, and a pin mounted in the other last part and arranged to cooperate with said hook to hold the last parts together, but being releasable from said hook by said sliding movement, said plate being deformable in its own plane by tension on the hoo-k 3. In a shoe last, a forepart and a heel part, separated by a cut permitting sliding movement of one relatively to the other, a bonding plate lying parallel to the plane of relative sliding movement and mounted in one of said last parts, a resiliently supported hook on said plate, and a pin mounted in the other last part and arranged to cooperate with said hook to hold the last parts together, but being releasable from said hook by said sliding movement. v
4:. In a shoe last, a forepart and a heel part, separated by a cut permitting sliding movement of one relatively to the other, a bonding plate lying parallel to the plane of relative sliding movement and mounted in one of said last parts, a projecting hook on said plate, and a pin mounted in the other last part and arranged to cooperatewith said hook to hold the last parts together, but being releasable from said hook by said 'sliding movement, said plate having a slot adjacent said hook to permit the hook to bend in the plane of the plate in order tobe forced tightly over the pin.
` K 5. In a shoe last, a forepart and a heel part,
separated by a cut permitting slidingmovement of one relatively tothe other, a bonding plate lying parallel to the plane of relative sliding movement and mounted in one of said last parts, a projecting hook on said plate,
'and a pin mounted in theother last part and arranged to cooperate With said hook to hold the last parts together, but being'releasable from said hook by said sliding movement, said hook being connected to said plate by a resilient shank, whereby said hook may bend in the plane of the plate in order to be forced tightly over the pin.
In testimony whereof I have signed my name to this speciiication.
