(Cl. 12-33) This invention relates to shoe repairing ma -ing lever has reached the end of its downward chines and "more particularly to a machine espe movement, cially designed for applying patches or taps vto shoe soles. The object of the invention is to provide a lshoe repairing machine of simple and‘inexpensive con Figure 5 is a perspective view of the stationary slotted head, guide block and a portion of the struction bymeans of which patches or taps may be cemented to the toe or’other portion of a shoe plunger detached, Figure 6 is a transverse sectional view taken `on the line 6_6 of Figure 4, and Figure 7 is a detail vertical sectional View illus sole with greater facility and vmore economically trating a modified form of heating unit. than heretofore. The improved shoe repairing machine formingl 10 the subject-matter of the present invention com ' A further object «of the invention is to provide a shoe repairing machine including an anvil or support and a vertically `movable shoe holder coacting therewith for kapplying pressure to the 15 tap or patch during the cementingoperation, said anvil or support having a heating lunit housed therein to insure rapid drying ofthe cement and thus expedite application of the patch to a shoe sole. 20 A further object is to Aprovide a 4shoe repairing machine comprising a standard having an over hanging stationary head formed with an angular slot and on which is mounted for lateral swinging movement a pivoted block constituting a guide 25 for the plunger of the shoe supporting element, there "being an operating lever pivotally‘rnounted on the guide block and operatively connected with said plunger whereby, after pressure on the patch has been effected, lan initial movement im 30 parted'to the lever -will elevate the shoe-supporting element above the anvil and `a further move prises a base 5 having a standard 6 arising there from and provided with laterally extending arms l, to each of which is rigidly secured or formed integral therewith an enlarged stationary head 8. 15 Any desired number of repair units may be mount ed on the base 5, two complete units being shown in the present instance, and as said units `are identical in construction a detailed description of one will suiiice. The head 8 of each repair unit 20 is provided with a smooth flat outer face 9, and opening through the bottom of the head is a slot I0 provided with an angular extension II, the purpose of which will be referred to hereinafter. Pivotally mounted on the flat outer face 9 of the 25 head 8 by means of a screw or pin `I2 is a guide block I3 having a dove-tail channel I4 formed inthe outer face thereof and in which is slidably mounted for reciprocating movement a corre spondingly shaped plunger I5. A vertical slot I6 is formed in the wall of the channel I4 and opens ment thereof swing -the guidejblock carrying the vthrough the bottom of the block, as best shown plungerand supporting element laterally-of Vthe in Figure 5 of the drawings, and this slot I6 nor machine so asto permit convenient removal of 35 the repaired shoe from said supporting element. A still further object of the invention 'is gen erally 'to improve this class of machines so as to increase ~their utility, durability `and eñiciency. Further objects and V'advantages will appear Vin “10 the course of ‘the following specification. I In the accompanying drawings forming >a part of this specificationy and in which lsimilar nu merals of reference indicate corresponding parts in -all the figures of the drawings: 4.GII Figure l is a side elevation, partly in section, of yal shoe >repairing machine embodying the lpresent invention, ' ' Figure 2 isa horizontal sectional view taken `on the line 2-I2 of ‘Figure 1, 5S f :Figure Y3 is a `vertical sectional view vtaken on the line 3-3 of Figure l, . ` .Figure 4 is an enlarged .detail yside :elevation showing the .position of the shoe supporting ele 55 ment .and its `associated parts when the «operat mally registers with the slot Ill in the enlarged head 8 to permit the passage of a pin Il extending I laterally from the plunger. The lower end of the plunger I5 is provided with a reduced extension I8 to which is detachably secured a shoe supporting element I9. -The upper portion of the shoe sup porting element I9 is provided with a- socket 20 to receive theextension I8 of the plunger and com municating with said socket is a slot ZI defining spaced ears 22 through which extends a bolt or similar fastening device 23, by means of which the shoe supporting element may be detachably secured to the extension of the plunger. The intermediate portion of the shoe supporting ele ment I9 is preferably curved laterally While the free end thereof carries a toe plate 24 adapted to fit within a shoe, indicated at S. The lower 50 end of the shoe supporting element is formed with a slot 25 adapted to» receive a bolt vor other suitable fastening device 26 so as to permit the attachment of toe plates of different sizes and shapes according .to thekind of `repair work to be 55 2 2,129,437 performed. Disposed beneath the plunger I5 is a combined support and heating unit 21, said sup upper end open and normally closed by a remov able top or cover plate 29. The cover plate 29 is provided with a circumferential retaining ñange lamp, I make the support o-r anvil 4I shorter and place in the bottom thereof a resistance coil 42 of any suitable construction. It is preferred, however, to use an electric light bulb as the heating unit as by so doing the electric bulb may be readily removed and replaced by a new bulb whenever necessary by simply detaching 30 which receives and holds a pad 3I formed of the cover plate 29 and unscrewing the bulb from rubber or other yieldable material. Disposed within the tubular body 28 is a heating unit pref the socket 33, as will be readily understood. From the foregoing description, it is thought 10 that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed port comprising a tubular body 28 preferably formed integral with the base 5 and having its erably in the form of an electric bulb 32, the lower end of which is detachably fitted in a standard socket 33 connected in a lighting circuit 33’ in cluding a switch 33”, as shown, and the purpose of the heating unit is to hasten the drying action of the cement when applying a patch to the sole of a shoe. Pivotally mounted at 34 on one side of the guide block I3 is an operating lever 35, the piv 20 oted end of which is formed with an angular extension» 36 to which is pivotally connected, at 31, one end of a connecting link 38, the opposite end of which is pivotally connected, at 39, to the adjacent portion of the plunger I5. A suit 25 able stop or rest 4€! is secured to one side of the guide block I3 and on which the adjacent por tion of the operating lever rests when the plunger is in lowered position. In operation, the toe or other portion of the shoe S to be repaired is first skived or beveled in the usual manner to receive the patch P, after which said patch is coated with cement or other suitable adhesive and applied to the treated portion of the shoe sole. Assuming the 35 parts to be in the position shown in Figure 4 of 30 the drawings, the shoe with the patch in position thereon is placed on the supporting element I9 and the lever 35 swung upwardly and laterally, thereby bringing the supporting element I9 with 40 the shoe in position thereon directly above and over the support or anvil 21. With the parts in this position, the pin Il will aline with the slots IIJ and I6 and, by pressing downwardly on the lever 35 until it engages the stop 4D, the link 38 45 will force the plunger downwardly so as to cause the toe plate 24 to press the patch against the rubber pad of the anvil and in which position it will be held until the heating unit 32 thor oughly dries the cement. The rubber pad 3i 50 equalizes the pressure on the pad so as to cause the patch to conform to any irregularities in the surface of the shoe and thus produce a neat job. It will here be noted that, when the lever 35 is unnecessary. ' ' Having thus described the invention, what is 15 claimed as new is: 1. A machine of the class described comprising a standard, a stationary slotted head carried by the standard, a slotted guide block pivotally mounted on the head, a plunger movable verti 20 cally within the guide block, a shoe supporting element carried by thel plunger, a support dis posed beneath the shoe supporting element, a pin carried by the plunger and extending through the slots in the guide block and head 25 respectively, and a lever operatively connected with the plunger for pressing the supporting ele ment and a shoe carried thereby against the support to cement a patch'on said shoe. 2.
