This invention relates to machines foruse rear end ofits last as it issupported on the work support of anassembling machine pre paratory 'to'being' secured to the last by the mac 'ne. 1 1

'Objects of the invention are to render the handling of straight orunmoldedcounters, in the operation of assembling uppers in cluding such counters upontheir lasts,easier, more accurate and expeditious than hereto fore and generally to improve theoperation of the assembling machine. v

Featuresof the invention consist in an organizationfincluding a shoe support movable toward and from the machine and clamping means in the pathof movement of'a shoe on said support arranged to hold the counter portion 'of' the shoe upper against the last: during its movement toward the machine 'so' that there will be no chance for the parts to be. displaced from the position in which they have been placed by the operatorQ: As'herein shown, theclamping means is movable by pressure of the shoe against it to cause'thef upper to be pressed against the'rea'r end of the last. The clamping means may-be held toward the shoe by resilient "means, and .a stop may be provided to arrest outward movement'of the clampingmeans before the outward movement of the shoe support is completed to cause the clamp and shoe to separate. The clamping means may, asshown, comprise a bar pivoted to the shoe support and bifurcated at its upper end, the bifurcations being formed with inclined surfaces which rest against the rear end of thesboe upper and hold the upper and counter against the last at the corners of the last, the space between the bifurcations permitting the operation of. the tacker of an assembling machine in fasteningthe upper and counter to 1925.

A link 40sis:piv.oted at one end to the machine frame and at the other end to a stud 42 fixed: in the bar 36, the link being normally in a down-- wardly and outwardly inclined position.

Iihestud 42 is extended and bentinwardly to lie inithe p'ath" of 'movement' of the tubular memberS and is preferably providedwitha saroll'l-fi tobe engaged'therebyi As the work support iss-m'oved inwardly the slotted l'ower end ofthe bar36 moves with it, causing the bar to-swin'g about the stud 42 as=a fulcrum and causing mutual relative approaching :3: Y niovei'nentbetween the :presser '34" and a1s-hoe on. the last pin 16so-that by the time-the. member S engages the roll 46 the depressor 3i=has assume'da position over 'thie shoe bottom; preferably over the heel seat portion. Further: movement ofzthe member 8 causes the link 40 to move from the inclined position shown toward a vertical position and therefore effects a downward movement of the bar 36 and of the depressor 34, causing it to engagethe shoe bottomand to depress the shoe against the spring 10 to a predetermined position.

The mechanism for clamping the counter against the last during movement of'the shoe support'toward the machine comprises a AspringfiOinsented between the post: 8' and i the bar 50 tendsto holdthe bar and member M againstwapin'62 carried by a lever 64:1
