APPARATUS FOR USE IN .ATTACHING SOILES OR HALF SOLES TO BOOTS AND SHOES BY THE USE OF AN ADHESIVE.

Application filed August 31, 1927, Serial No 216,710, and in Great Britain. January 24, 1927.

This invention relates to improvements in apparatus for use in attaching soles or half soles to boots and shoes by the use of an adhesive.

The method of attaching soles or half soles to boots and shoes by the use of an adhesive, usually referred to as the cement ing process, is being increasingly used by repairers and manufacturers of boots and shoes. In carrying out this cementing process, a sole-laying press is employed which may comprise a metal container adapted to support a .more or less yielding cushion and screw press mechanism by which the prepared boot or shoe may be pressed firmly into contactwith the sole or half sole, the pressure being maintained for some time until the adhesive has set su'lli" ciently to warrant the removal of the boot or shoe from the press.

A suitable construction of press for the purpose stated is described in the speciiication of our British Letters Patent No. 233,- 028, such press being of Simple construction and being adapted for hand manipulation. Usually the press is constructed in duplex form so that a pair of boots or shoes may be dealt with and the press then put aside to allow the adhesive to set. In View of the fact that the boots or shoes require to be maintained under pressure for a very much longer period of time (for the adhesive to set sufficiently as aforesaid) than would be taken. by a reasonable expert workman to arrange the parts of the boots or shoes in the press, a number of such presses are necessarily required so that the workman may be continuously engaged in arrang ng the parts of the boots or shoes in, successive presses without the risk of removal of the boots or shoes from the presses before the adhesive has set sufiiciently.

The minimum number of presses that may thus be maintained in use will of course depend to some extent upon the skill of the workman and to some extent upon the kind of boots or shoes that are to be soled or resoled, and also upon the time it takes for the adhesive to set, but in any event a workman would require to be provided with four such presses and these either occupy a very considerable area of the work bench or, after arranging the parts of the boots or shoes therein, the workman has to lift the presses from the bench and place them upon a shell or rack provided for their reception and this obviously entails not only considerable physical exertion but also occupies a not inconsiderable measure of time in moving the presses to and from said shelf or rack.

The present invention has among its objects to avoid the disadvantages referred to and to provide apparatus for the purpose specified which while occupying a minimum of floor space greatly facilitates the carrying out of the method oi. attachingsoles or half soles as hereinbefore described.

According to the invention, a support is provided that adapted to carry a plurality of presses and that is so arranged that the pres .s may successively be disposed in, a position most convenient to the workman for arranging the work upon the presses, while the remaining presses are disposed clear of the press for the time being in use. Thus according to one construction the support may be arranged to rotate, preferably about a horizontal axis, and to carry a number of presses, for example four, disposed symmetrically about the axis of the support.

By arranging the support to rotate upon a horizontal axis, a minimum of floor space will be taken up by the presses andthe apparatus carrying the same.

According to the invention, moreover, means may be provided for holding or looking the support in the positions at which the respective presses are to be disposed while the work is being arranged thereon or removed thereiirom. Thus the rotatable support may be provided with a series of holes or recesses corresponding in number and (lIlSpOSltlOD, to the presses which the support is adapted to carry, and means such as a pin or pins or the equivalent may be provided that is or are adapted to be engaged sue cessively with the respective holes or recesses on rotation of the support to dispose the presses successively in position for use.

The invention further comprises the features hereinafter described.

The invention hereinafter described, by way of example, with reference to the accompanying diagrammatic drawings, in which Figure 1 is a side elevation of a sole attaching apparatus constructed according to the invention and adapted to carry four presses, one press being shown in the position that it occupies while the work is being arranged thereupon; Figure 2 is a top plan view corresponding to Figure 1; and Figure 3 is a vertical longitudinal section through the apparatus on line AA of Figure 2.

In carrying the invention into effect according to one construction and with refer ence to the accompanying diagrammatic drawings, a suitable frame, which ma comprise a pair of standards a held rigidly at a determined distance apart by means of rods or cross-bars (1 is provided for the support of a press-carrying element b rotatable upon a horizontal spindle 0 carried in bearings a provided at the upper ends of the standards a, which spindle c is preferably held against rotation by means of set screws a The bearings a are preferably formed by boring holes through bosses formed at the upper ends of the standards a in order to simplify manufacture and to avoid the use of caps, bolts, nuts and other fittings. The press-carrying element 1) may conveniently comprise a pair of star-shaped discs b having centrally disposed bosses b by which they may be rotatably mounted upon the spindle 0, the discs I) each preferably consisting of a circular part 6 having a number of radially extending arms b corresponding to the numberof the presses to be supported by the apparatus, the outer ends of opposite pairs of which arms I) may be connected together by means of transversely disposed ,bars I) of angle or other suitable section. The radially extending arms I) may be provided with oppositely disposed inwardly directed flanges 6* arranged, for example, tangentially to the bosses 1) upon the discs b and the successive pairs of oppositely disposed flanges b may be disposed, in the example illustrated, at right angles, the flanges b serving at the same time to stiffen the discs.

The pairs of oppositely disposed flanges '6 upon the discs 12 are adapted to form hearings to receive the sole attaching presses d, and, in order that'the presses d may be readilydropped into position and securely held upon the press carrying element, the

flanges b may be provided with flat faces with which corresponding flat under faces of laterally extending lugs d upon the press 0! may engage, so that this the press (1 will not be liable to rotate about the positions at which it is supported upon the flanges b on the discs 6 more especially if the crossbars 1) connecting the arms b of the discs I)- are adapted to engage with, and to form an additional support for, the front under 7, part of the press 01. In order that the press (I may be securely held in determined position upon the flanges b of the discs b pairs of oppositely disposed lugs b may be provided to extend'inwardly from the discs 6 the lugs I) being provided with semicircular or other recesses 6 adapted to receive the outer ends or parts of the lugs (5 upon the press d. A cover plate I) may be provided for each. lug b which cover plate I) is applied in position above the lug (l of? the press (Z and is screwed down by means of bolts 1) or the like to clamp the press (I in position with its laterally disposed lugs a" engaged within the semicircular or other recesses in the lugs I) upon the discs I). It will be understood that the semicircular or other recesses 12 in the oppositely disposed pairs of lugs b are set apart at a determined distance and are preferably so formed that the press (1 may be readily dropped into position, while when in position it is securely held against lateral movement.

A series of holes b may be provided in one or both of the discs I) conveniently in the outer face and adjacent the periphery of the circular part b thereof, the series of holes 7) corresponding in number and disposition to the number of presses that the apparatus is adapted to carry, and a pin or stud c is provided in determined position upon a pivoted lever e to engage with the holes 5 successively whereby the press-carrying element 1) may be held against rotation with any one of the presses (I in position at the front of the apparatus for arranging or for removing the work. The'lever e is conveniently pivoted upon a boss a at the upper end of the standard a by means of a bolt 6 or the like and. the lever 0 preferably extends forwardly to a convenient position at which it is provided with a handle 0 for operation by the workman. The lever a may be provided with a rearward extension 0 beyond the pivot e, vhich extension 0 may be adapted to engage with a spring f carried in a recess in a lug a at the head of the standard a and serving to press the pin or stud 6 upon the lever a into engagement with the respective hole or recess b". I

The central circular art b of the disc I) is preferably provide with an uninterrupted'annular surface 1) upon which the pin or stud 6 may ride when the press-carry element is being turned upon the spindle c to bring the respective press supports into position for arranging the work. According to a modification the spring f may be dispensed with, and means may be provided whereby the lever e engages frictionally with the standard a so that notwithstanding vibration to which the apparatus may be subjected in the ordinary way, the lever 1: will be held in the position to which it is moved. The lever will thus be frictionally held either in the position in which the pin or stud e is engaged in the respective recess b to hold the press carrying element against rotation, or in the position in which said is screwed into the standard 0..

pin is disengaged from the recess to permit the press-carrying element to be rotated for presentation of another press at the front of the apparatus. For this purpose the upper end. of the standard a. may be formed with a flat surface against which the pivoted part of the lever a may be pressed by means of a spring washer that is interposed between the lever c and the head of the bolt 0 constituting the pivot. If desired the lever e or the standard a, or both, may be pro vidcd with facing pieces that ensure a sufficient frictional engagement when the bolt 0 It will be understood that the lever mechanism hereinbefore'described may be provided, as shown in the drawings, on both sides of the apparatus.

In the use of the apparatus hereinbefore described, the workman will in the first instance secure the press-carrying element Z) against rotation by causing the pin 0'- upon the lever e to engage in one of the recesses b and he will then fix a press (Z in position as hereinbefore described. He then arranges the parts of the boot or shoe in the press and having manipulated the usual hand wheel d whereby pressure is brought to bear upon the work either through a kind of iron last or, as shown in the drawings, upon a bridge-piece (Z that. engages upon the fore-part of the boot or shoe and. upon the heel and part of the last, he then releases the press-carrying element b by withdrawing the pin a from the respective recess 1) and rotates the element 6 to a position such that the pin 6 may be engaged with the succeeding recess 5, whereupon another press cl may be similarly secured in position, and so on until the full complement of presses has been applied. By the time he has arranged a boot or shoe in each press, the boot or shoe first operated upon will be ready for removal and for replacement by the parts of another boot or shoe. Thus it will be understood that by the use of the apparatus according to the invention, the workman may be engaged continuously in arranging the parts of the boots or shoes in the presses without being required to lift or to move the presses from place to place in the manner heretofore found to be necessary. Furthermore the apparatus does not require substantially more floor space than the area that would be occupied by two presses.

It will be understood the press-carrying element may be adapted to carry any desired number of presses which are preferably arranged symmetrically about the axis of the element so that the latter may be easily rotated. It will furthermore be understood that the invention is not limited to the details of construction hereinbefore described. Thus the recesses b may be replaced by pins or other means adapted to engage with a recess or the equivalent in the lever e.
