Patented Oct. 31, 1933 UNITED STATES SHOE. HOLDER Robert Lawson, Beverly, Mass, assignor to United Shoe Machinery Corporation, Paterson, N. J-., a corporation of New Jersey Application. July 9, 1930. Serial No.. 466,615 3'7Claims: (Cl. 1 2126) This invention relates to holders for shoes. It may usefully be employed for presenting and retaining a shoe for the attachment of its heel, though capable of other applications.

An object of the invention is to so hold a shoe fora-n operation upon it, that it occupies a definite position, this preferably being determined longitudinally, transversely, vertically and angularly, and requiring only simple manipulation by the operator, who need not give thought to the various relations. which must be established. In accomplishing this, I employ novel means. for locating the rear portion of a shoe, together with means movable against the forward portion, there being preferably opposite members movable si-,

multaneously by the operator into engagement with the shank, for locating it transversely and angularly This positioning action may be with respect to a pressure-abutment, as oneby which a heel is held for attachment. The forward loeating means, regardless of" its effect upon. the angular relation of the shoe; may serve to support it, as by a portion extending beneath. the shoe-sole; The rear positioni'ngmeans isshown as including both a back-stop, which fixes the longitudinal relation of the work, and means, as a counter-fork, which determines the transverse relation offlthis portion of the shoe to be held. The forward positioning 'means, in addition to locating the shoe transversely and angularly and supporting it as just noted, maybe utilizedto' urge the shoe longitudinally against the back-stop. For this latter purpose, in the illustrated construction the opposite members grasp. the shoe and. then move bodily with it toward the backstop.

Another'object of. the invention isto establish thecorrect relation. for the operation. upon; it: of a shoe held asabove-outlined. The holder has associated witl rxit. a: last-support, and thev support and holder,. the latter" carrying a shoe in 'which'is a'last, are relatively movable to bring into contact. the support and last. With: the work. thus positioned, the holder' may be locked to prevent separation of the last and support. Means disclosed for actuation by the operator to unlock. the holder at the completion. of-the- 0peration upon. the work; Thisv release is conveniently effectedthrough the member by whichthe operator actuates the shoespositioning means;

Fig. Lisa vertical sectional detail onthe-line IV--IV of Fig. 2.

At A. appears a base, consisting of. a vertical portion 10 and; a generally rectangular'top-plate 12. The plate may be adjustable horizontally thereon along ways 14. Rising from. this plate isa post 16, having,.upon a'universally' movable bed-plate, anupper' surface 18 furnishinga support for the cone of a. last contained in' a shoe to-bepperated upon- The base also has mounted upon-ita holder for-the". work. 'Near each corner of the plate 12 is astandard 20, andbetween the forward and rear pairs of standards are respectively" fulcrumed. levers B and C, each consisting of a pair of outer approximately horizontal. arms 22, 22 and a depending. central. arm 24.. Pivotedi upon the. arms 22 is ahorizontal carrier frame 26: at

. the rear; of which. is an. upwardly extending. portion 281. At thecenter and upon. the topof this portion 28 is secured'a gage member in; the form of a back-stop 30: having. a. forward reduced edge arranged. to enter the rand-crease of a: shoe near the centerof. the counter-portion: A.gage-fork has. an arm 32' pivoted upon the portion 282211, each: side of theback-stop, a rounded end 34. of each arm being arrangedito: engage" the counterportion: of th'enshoe below the rand-crease. Intermeshing teeth '36 connect thearms of the fork'to. oscillate together, and they arexfbrCed into engagement: with the shoe? by spring-factuated .p'lungers 38, 38 .movable horizontally in the carriers-portion 28;. By these" fork-arms; a shoe longitudinally'positioned by the back-stop has its rear extremity locatedin adefinitesttansverse relation.

Guided. in horizontal depressions ati theouter sidesof. the carrier-portion 28, below theibackstoptandth'e fork, is a slide 400i u;-form, its arms extending forwardly and. normally urged; in this direction. by a. spring 41. This spring is shown' asv of: the leaf-type secured at its lower end; to the. plate 12 and resting at itsuppen extremity against the slide, At the forward endaof each arm: of the slide; a bell-crank lever D is fulcrumed upona vertical axis- An upwardly and forwardly extending arm 42 of. eachv lever has an inner contact member 44 lying in a plane just above the back-stop 30; As bestsh'ownirr Fig. 4 ofithedrawings, this contact-end of, each lever a depressionv between. horizontal inward pro-' jections 46, 46. The width of the depression is such as to receive the edge of the sole of a shoe to be operated upon, the lower projection supporting the weight of the forepart of the shoe and the upper preventing its upward displacement. Each lever D possesses an inwardly and downwardly inclined arm 48, joined by a link to a slide E, made up of a cross-bar 52, to the opposite ends of which the links are articulated, and a plunger 54 guided in a bore in the forward extremity of the carrier 26. Rising above the plunger 54 is a projection 56, entering a camslot 58 in a segmental extension 60 from a handlever 62 fulcrumed for horizontal movement upon the carrier above the plunger 54. The contact members 44 of the levers D are located opposite that portion of the sole of a shoe carried by the holder, which has its edges substantially parallel and equidistant from the longitudinal axis of the shoe-bottom. The sole-receiving depressions of the contact members are "equally spaced from the longitudinal center of the holder, with which the axis of the shoe is to be made to coincide, and are oscillated oppositely at equal rates bytheir connection to the handlever 62. Consequently, when the levers D are swung in by pulling the hand-lever forward, their contact-members, upon engagement with the sole of the shoe positioned at the rear by theback: stop and counter-fork, will move said shoe in the a direction necessary to establish its desired angular relation and the transverse position of the 'forepart, and will retain it against vertical displacement by the engagement of the projections 46, 46 with the opposite sides of the sole or the sole and welt. .After the cam-slot 58 has thus thrust the contact-portions of the levers D against the opposite edges of the sole, continued pull upon the hand-lever applies to the levers D forces tending to push back the slide 40 against resistance of the spring 41, shifting the levers D bodily in this direction. This causes the lever-portions 44 to be simultaneously pressed upon the sole-edge and moved rearwardly over it. As aresult, the rear of the shoe is seated firmly against the back-stop and is now correctly positioned in all directions. The contour of the slot 58 is such that frictional engagement between the projection 56 and the slot-wall retains the hand-lever against accidental rearward movement, and the work locked in the holder until'the operator shifts the lever in the opposite direction.

In operations of the character of heel-attaching, it is customary to apply a measuring pressure to the work, to establish a definite initial relation to the operating instrumentalities regardless of the height of the last and the thickness of the shoe-parts, and then to impose a final clamping pressure in preparation for driving the attaching nails. My improved work-holder is organized to cooperate with pressure-receiving means. The particular form of such means and the manner of its action is of no consequence, as far as this invention is concerned. I have illustrated a portion of a head F adapted to act as a pressure-abutment. This head may be provided with any suitable heelor lift-holding and naildriving means. To create the pressure between the thus-supported heel and the heelseat of a shoe in the holder, the base A, with the holder, may be elevated by such mechanism as that acting upon the Jackof Letters Patent of the United States No. 446,885, Pope, Feb. 24, 1891. Ascent of the holder, under the influence of the trea mechanism of the Pope patent, with the consequent contact of the heelseat of the shoe in the holder with the heel carried by the head, will lower the carrier 26. The carrier is normally elevated, with the shoe-engaging elements at their maximum height above the surface 18 of the post 16, by a spring 70, surrounding a rod '72 joining the arms 24 of the levers B and C. This spring exerts its expansive force upon an enlargement of the rod and against the post 16, through an opening in which post the rod passes. Contact of an enlargement at the end of the rod opposite the spring with the outer side of the post limits the upward movement of the holder. Said holder is preferably releasably locked against reverse movement, away from the support-surf ace 18, by a latch 74 pivoted upon the base plate 12 and forced by a spring-actuated plunger '76 against a series of teeth '78 formed upon the under side of a portion of the rod 72. The teeth are so inclined that during the depression of the holder under the influence of the head F they slip over the pawl, but are held against the reverse movement by the engagement of said pawl. When the holder is thus locked, the final pressure may be applied by further elevation of the base A under power, this forcing the work more firmly against the nailing head F as an abutment. After the nailing, or other operations, have been performed upon the shoe in the holder and the clamping pressure released, the operator pushes rearwardly the lever 62. Extending from the under side of ,the plunger 54, below the projection 56, is an arm fast upon the plunger. The lower extremity of the arm is united by a pin-and-slot connection 82 to a link 84, the opposite end of the latter being articulated to a depending portion of the latch 74. The pin of the connection 82 bears such a relation to its slot that during the forward holder-actuating movement of the handlever it travels idly. Upon the opposite or rearward movement of the lever, when the operator releasesthe shoe from the holder, the pin strikes the rear extremity of the slot, and before the forward end of the cam-slot 58 has reached the projection 56 it disengages the latch 74 from the teeth '78, freeing the rod 72. The spring '70 there .upon expands to restore the carrier and shoeengaging elements to their normal elevated positions.

To sum up briefly the operation of the holder, the operator places a shoe S with the rear edge of its sole 3 above the stop 30 and its counterportion between the fork-arms 32, and forces it back until the stop is seated in the rand-crease and the fork-arms are opened by the pressure of the counter-portion against the ends The shoe is thus located in a substantially correct longitudinal relation by the entrance of the stop 30 into the crease and laterally as to its rear portion by the pressure of the fork-arms 32 actu= ated by their plungers 38, and it is also positioned and retained against vertical displacement at this position by the presence of the stop in the crease. This having been accomplished, the operator raises or lowers the forepart of the shoe as may be necessary to horizontally aline its soleedge with the depressions in the contact portions 44, 44 of the normally separated levers D, D, and pulls forward the hand-lever 62. Consequent rearward movement of the plunger 54 and its connections swings the arms 42 of the levers D, D until the projections 46 of their contact portions embrace the sole-edges at points equally separated from the longitudinal axis of the shoeas. in the previouslwmehtioned patent.

bottom. this engagement, 'thefloscillation of the lovers]? ceases and continuedfmovenrent of the hand-lever by the operator causesjjr'earward travel ofthe slide 40 against its spring; 41,

carrying the lever-arms 4'2 and their contactportions along. the sole-edge. The effect 'ofthis 'is, to more firmly seat the work againstvthe backstop, fixing. it in thecorrect longitudinal relation.

The positionof the. forepart, considered both transversely at right angles to the longitudinal axis/of the shoe and; angularly above a. pivotal point at the back-stop, was attained upon termination of. they inward movement. of the. contactportions. of. the levers.
