To all whom it'ma-y concern:

Be it known that 1, WILLIAM A. BOND, a

citizen of the United States, residing at Lynnfield, inthe county of Essex and State of Massachusetts, have invented certa n Improvements in Shoe-Supports, of which the following description, in connection with the accompanying drawings, is a specification,

The embodiment of the invention herein shown is particularly suitable for supporting shoes for the operation of the'machine which forms the subject matter of United States Letters Patent No. 1,085,595, granted February 3, 1914,to Charles De Minico.

The object of this invention is to provide a shoe support which will facilitate the presenta-tion and manipulation of a shoe while it is being operated upon by a machine which inserts tacks or other fastenings in the heel seat or by a machine for performlng other operations upon the heel or rear portion of a shoe.

An important feature of the invention comprises a last engagmg device and a sustainer therefor, which have relatively slid-- ing contacting surfaces that are curved about a center located a substantial distance above the bottom of the last on the engaging device to direct movement of the device in an The construction enables the last engaging device, which may be a lastspindle, to be positioned either vertically or at various inclinations to the vertical so that the heel seat portion of the last may be readily brought to a level position for the reception of heel seat lasting tacks or for other shoemaking operations. In the construction shown the spindle has av spherically convex base and the spindle support a spherically concave face which engages the convex base of the support, and the curvatures of theeIigaging faces are struck from points substantially above the end of the spindle and pref V erably from the samepoint A "-A further feature of thel inventioncon sists in means for limiting movement of the 1 various functlons. The pro ect1ons on the an; are-unequal for a purpose to beisuhspindle baseso that the movement of the, last carried by the spindle will-be limited. to a Specification of Letters Patent.

distance less than the width of the heel seat of the last. g o

'Other features and objects of the invention will be apparent from: a consideration of the following description and claims in connection with the accompanying drawing,

in which Figure 1 is a side elevation of the improved ack and a portion of the machine to which it is applied; Fig. 2 is a sectional view of the spindle for supporting the last and the head for supporting the spindle in adjustable relation to the operative parts of the shoe machine; Figs. 3 and 4 are sectional details taken respectively on lines 33 and 41- 1: of Fig.1.] The jack proper is supported by a lever 2 pivoted to, the main frame A of the machine o by a bolt, 4. The lever 2'is given movement by a, rod 6 in connection with a cam 8 on the main shaft of the machine in timed relation to the action of a pounding up element 10 of the machine and a side ponnder pin 10 on a slide 13 having aslot 15 through c which passes the main shaft of the machine.

To the upper end of the slide =13 is clamped by a bolt 17 a rod 1 1- on the upper end of which is a thumb nut 16/ Between the thumb nut 16 and a yoke 18, to which the rod 6 is attached, is a spring 20. As the projections, of the cam '8"ac'tj downwardly upon the pin 10 on the slide 13, which is connected with'the rod 1 1, it imparts movement to the yoke 18 through the spring20 and thence by the rod 6 jointed at 21 to the right-hand end of the lever 2 which turns about the bolt 4 as a fulcrumand raises the left end of the lever and the jack supported thereon. Upon release of downward pressure by the cam 8 a retractile spring 22, called the jack springyraises theright end of the lever 2 and restores the jack to its lower or normal position-The interpositionof the spring 20gives the jack a resilient support and by taking up the excess movement of cam 8 prevents the applicationof morefupward pressure against the operative parts of the machine than is neces sary for the properrperformance of their seduently explained. The end24 of the lethe bracket 42 upon thering.

ver is bifurcated and each bifurcation is PlOVldBdWIlth a slot 26 through which passes a bolt. '28. ,By this bolt a .member 29 is clamped to the bifurcation of the lever 2 and by means of the slots therein it may be adjusted toward and away from the ma- .chine. lVhen clamped in adjusted position in the slots 26 the bolt serves as one axis of a universal joint which supports a foot block 30. The other aXis of. the universal joint is provided'byscrews 31. passing through lugs movement of the entire jack in so far as .permitted by the stop ring 44, to be pres ently described.

Pivoted to the footblock ee'b a bolt 34 is a member 36 having screw-threaded hole at the upper end and provided at the lower end with a flattened extension hav1ngtherein a slot 38. By means ofthis slot'and a bolt '40 the angular position of the member 36 may be adjusted and rigidly secured relatively to the foot block 30.

To prevent the jack from swinging out too tar a stop-1s provided which consists of .a bracket 42 attached to the frame of the machine and a stop ring 44 which embraces themember 36. of the bracket and is pivoted to-the base 42. The ring 44 is frictionally held in adjusted position by a screw 41 which clampstogether the split sections of When the jack is swung outwardly from its operative position, shown in dotted'linesin Fig. 1, it

is caught by the stop ring 44 and held in the position shown in full linesin the same figure. The distance the jack moves outwardlymay be varied by adjusting the ring at an inclination to the horizontal and tightening the screw 41.. 1

The'upper end of the member or support 36 is slitted and screw threaded, and into it a threaded rod 46 is screwed. This rod may be rigidly clamped in adjusted position by means of asplit ring 48 and a screw 50. Attached to the rod 46 bya pin 52 is a head 54 whichis shaped like an inverted dome andhas a heavy rounded peripheral portion or rim adapted to be grasped'by the hand. Inset into the topof the member .54 and secured thereto by machine screws 56 is a' plate 58 of uniform.-thickness having a slight concavity downwardand provided with'an opening 60. Theunder surface of the mushroom shaped base 62 of the spindle support 64 has a curvature corresponding to that of the-upper surface of the plate 58 withwhich it engages These surfaces are heldin-frictional contact by a screw 63 inserted through the hollow spindle support 64 and, passingthrough a hole of the size of the screw in-the base 62 of the support 64,;through the-opening -of theplate 58 cycle of the machine.

and into screw threaded engagement with a retaining plate 66. This plate is larger than the opening 60 so that once the screw 63 is properly adjusted the spindle base 64 will be held frictionally against the top plate 58 of the dome but will be capable of movement within the area prescribed by the opening'60.

The last pin 68 which is screwed into the top of the support 64 is adapted to engage a hole in a last.

The curvature of the surfacesof the plate 58 and of the lower surface of the mushroom head 62 on the spin dle support 64 is struck from apoint so far above the top of the last pin and the size of the opening 60 is such, that as the support 64 is made to pass through the circle prescribed by the screw 63 and the opening 60 a point on the periphery of the heel portion of the last will describe a circle of substantially the size of that along which ing driven and will then relieve the pressure and permitthe jack spring 22 to lower the shoe and avoid drag of the wiper over the upper during its retreat. The cam of the bottom beater or pounding-up member is timed to strike two blows during each The first blow is struck after the wiperhas retreated to uncover thev stock and while the shoe is released from hard upward pressure and the of the bottom rest 23 which sinks into the innersole and allows the shoe to rise higher in response to the longer projection of the jack cam, so that in effect the second blow of the bottom beater on the shoe is harder thanthe first blow. y

From the accompanying drawing and the foregoing description the advantages and utility of the-device will be apparent. The movement of the jack upon the pivots 28 and 31 enables the operator to readilyplace the last with its accompanyingshoe parts upon the'spindle while in its outward position, and to move-it toward the machine in proper relation to the operativeparts thereof. 7 I I The adjustment provided by the pivot bolt 34:, the slot 38 and clamp bolt 40 enable the operator to adjust andsecure the support 36 at any angle with respect to the machine within the range of the slot 38. Thescrew rod 46 and split ring 48 provide adjustment as to height to accommodate the jack to various sized lasts and different machines. The adjustment of the last pin 68 by means of the convex surface of the mushroom base of the spindle 64k and the corresponding surface of the plate 58 is particularly important. The frictional engagement of these surfaces furnishes, when pressure is applied either by blows of the machine downward or by moveinent of the ack upward,

a positive connection between the spindle and the jack. When,'however, no pressure is being applied to these surfaces they freely slide over each other and permit the operator to easily, quickly andaccurately adjust the work so as to level the last and'present all portions of the work acted upon atthe same height relative to the operating devices. Moreover if the jack is moved about the outer limits of itsipath of movement, that is, by keeping the screw 63 against the walls of the opening 60, the resultis that the nails and blows about the'periphery of the shoe heel will always be delivered at the same angle relatively to the bottom of the shoe or, what is the same thing, to the nail plate of the last. p

In using my invention with a nailing or slugging machine the support 36 may be held rigidly, theonly movement of theijack under the nailing nozzle being due to the sliding upon each other, of the curved'surfaces of the parts 58 and 62. In this case if the jack is kept to the outer limit of its path the jack spindle and last thereupon will describe a circle. of substantially the diam-. eter of that in which the nails or slugs are to be set in the heel. Hence, by this device little skill is required to set the nails or slugs about the heel at evenly spaced distances from the periphery thereof,

The operationof the machine will now be obvious without further explanation. It is to be understood, of course, that various modifications of the mechanism employed may be made without departing from the spirit of the invention. Hence the scope of the following claims, in which effort has been made to define the invention, should be interpreted with reference to, and as restricted only by, the state of the prior art.
