4 Claims.

My invention relates to a new and useful improvement in a lsole pressing apparatus adapted for use primarily in securing a sole to a shoe.

The invention is capable of use either when the same is to be used in attaching a half sole or a full sole to the shoe. While the invention is intended primarily for use in shoe repairing, from a description of the apparatus it will appear obvious that the invention may also be used in shoe building. The sole is now frequently secured to the shoe solely by glue or other suitable adhesive material and in order that the sole may be prop- `member with parts broken away and parts shown erly glued to the shoe, it is necessary that the sole be pressed to the shoe throughout its entire area for a suillcient length of time to permit the adhesive material to set or properly dry.

It is an object of the present invention to provide an apparatus whereby the sole may be securely and firmly pressed against the shoe throughout its entire area and whereby the drying of the adhesive material may be facilitated and hastened, thus reducing the time of use of the machine required for each operation to a It is another object of the present invention to provide in an apparatus of this class a last forming portion or shoe-engaging member which will serve to engage the inner portion of the shoe and press against the sole and heat the sole while the pressing is being effected, thus facilitating the drying of the adhesive material.

It is another object of the present invention to provide an apparatus of this class which will be simple of structure, economical of manufacture,

durable, and highly emcient in use.

Another object of the invention is the provision of an apparatus of this .classv which may be easily and quickly adjusted for pressing a half sole against a shoe or for pressing a full sole.

Another object of the invention is the provision of a stretching member mounted on a suitable last so that the upper part of the shoe may be pressed to form while the last itself serves to.

press the shoe thereto. Y

Other objects will appear hereinafter.

invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understoodv by a reference to the accompanying drawings which form a part of this specincatlon, and in which,

In the invention I provide a. base 15 having a standard 16 projecting upwardly therefrom, and on which rests a thrust bearing 1'1 upon which engages a table 18. A shaft 19 is journaled in the standard 16, the bearing 17, and the bearing 20 mounted in the recess 21 formed in the table 18. A conical sleeve 22 embraces the upper end of the shaft 19 and engages at its lower end within the circular flange 23 projecting upwardly from the table 18. The upper end of the sleeve 22 serves to support the bearing 24 in which is journaled the reduced end 25 of the shaft 19. The upper end of the sleeve 22 is embraced by the circular flange projecting downwardly from the supporting bed 27. Projecting upwardly from this supporting bed 27 are studs 28 in each of which are threaded the bolts 29 'securing a keeper -plate30 which spans a slot 31 formed at theoutwardly projecting supporting arm 32. 'This arm 32 has a pair of threaded openings 33 and 34 formed therein through which 'may be projected a presser screw 35, the upper end thereof being not faced as at 36 for reception of a hand whee 37.

The table 18 is provided with outer projected4 supporting brackets or arms 38 through the outer end of each of which is formed the opening 39. A presser bed 40 is provided having a recess 41 formed in its upper surface. Secured to the edges i2 of the bed 40 are a number of transversely `extended metallic plates 43 which overlie the longitudinally extended metallic plates 44, these plates being detachably secured at 4their ends to bolts 45 threaded into the edges 42. pverlying this network support is a layer of yieldable material 46 such as felt or the like. This layer is covered by the outer covering 47 formed from leather or the like, and secured to the edges 42 by the clamping band 48. The bed 18 is rotatably mounted on the standard 16 and a retractable plunger 49 is slidably projected through the lugs 50 and normally pressed by the spring 51, into the recess 52 formed in the bed l8. A cord 53 is attached to one end of the plunger 49 and also attached to the swingable pedal 54. The construction is such that upon pressing the pedal 54 downwardly, the plunger 49 will be retracted and the bed 18 may be rotated about the standard 16. When the bed 18 is in position so that the plunger 49 may engage in the pocket or recess 52, the presser beds will be positioned beneath the screws 35 on the respective supporting arm 32. Each of these presser beds carries a stud 55 having a flat faced portion 56 engaging in the flat faced recess 57 formed in the supporting arm or bracket 38. The stud 55 is projected through the opening 39. The construction is such that when the presser bed is raised so that the fiat faced portion 56 clears the fiat faced portion 57. the presser bed may be rotated on the stud 55 as an axis, the purpose ot which will appear hereinafter.

The arms 32 may be moved radially inwardly on the supporting bed 37 upon releasing the pressure of the keeper or clamp plate 30 on these arms. In Fig. 1 I have shown one of the arms extended outwardly, and I have shown the other arm pressed inwardly, the screw 35 which normally would be threaded into the opening 34 having been removed to permit this inward slidable movement of this supporting arm.

The device is used for pressing a sole 58 against a shoe 59 and retaining the same pressed thereagainst until the glue or other suitable adhesive has suiilciently dried to tightly aiiix the sole to the shoe. The screws 35 are adapted to engage a head 60 projecting upwardly from the shank 61 of a last section 62 which engages within the 'shoe. This last section is provided with a recess 63 communicating with a passage 64 and at its 'forward end the under-surface of this last section is cut away as at 65. This last section cooperates with a detachable section 66 having a nose 67 at its forward end and provided with a stud 68 projectable into the recess 65. Adjalcent the rear end of this section 66 is a housing 69 in which is positioned a spring 70 adapted to normally press the plunger 71 outwardly therefrom. The construction is suchthat when the sections are assembled together, the plunger 71 will engage in the passage 64 and serve to lock these sections together. The sections may be released from each other by pressing the plunger 71 inwardly by means of a wire or other suitable tool passed downwardly in the passage 64. Within the section 661s an electric heating element 72 which is connected by the cable 73 to a suitable source of electrical energy so that when the parts are moved into pressing relation, the -current may be turned on to facilitate and hasten the drying of the adhesive. Swingably mounted on the shank 61 by means ofthe pin 74 is a bracket 75 to which is connected intermediate its ends the resilient strip 76 carrying at its forward end the presser plate 77 adapted to engage and press outwardly the forward portion of the upper 78 oi' the shoe.

The rear end 79 of this strip 76 carries a heel engaging block 80 adapted to engage the heel portion 81 of the shoe and maintain the same pressed to normal form. A grip 82 is mounted on the strip 76 to facilitate its removal and placement in position. When in position, the rear end is angularly turned as shown in Fig. 4 against the resiliency of the strip 76 so that the desired pressure is obtained on the heel pressing block 80 and the presser plate 77. The device may be used for pressing either a half sole or a full sole on a pair of shoes. When used for pressing a half sole, the presser beds are turned so that the same lie parallel to the arm 32 positioned thereabove so that a pair of shoes may be placed on the presser bed extending transversely thereof and the presser rests positioned therein engaged by the screws 35. When it is desired to use the device for pressing a full sole on a shoe the presser bed is turned to extend transversely of the supporting arm or bracket 38 and the arm 72 is moved inwardly as shown in Fig. 1 so that but a single screw is in alignment with and positioned over the presser bed. In this way the device may be easily and quickly adjusted to desired positions for pressing a half sole or a full sole onto the shoe. The slidable mounting of the arms 32 also permits of the necessary adjustment to accommodate shoes o! various sizes. In Fig. 11 I have illustrated a slightly modified form of the invention in which a rockable shaft 83 is mounted on a standard shoe repair bench 84. This shaft 83 serves to support the arms 85 and 86. The arm 85 carries the presser bed 87 while the screw 35 is threaded through the arm 86. When the device is moved to position for use, it is as shown in full lines in Fig. 11, and is locked in position by the latch 88. When it is desired to use the bench for other purposes the presser device may be moved to the dotted line position shown in Fig. 11.

While I have illustrated and described the preferred form of my construction, I do not wish to limit myself to the precise details of structure shown but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.
