20 Claims.

This invention relates to improvements in shank and patching cementing presses for footwear.

Heretofore presses for patching footwear were designed to accomplish one particular operation and were useless when doing other operations than that for which the press was designed. Furthermore, several operations, such as patching an upper or toe of a boot, or cementing the shank of a boot or lady's high-arch shoe, were practically impossible without damaging the boot or shoe.

While half soles can be applied with this invention, it is notdesigned primarily for halfsoling operations, and is not to be confused with such presses. A most difiicult operation is the cementing of the half sole to the shank of a cowboy boot or a high-arch ladys shoe without breaking down the arch or getting the shoe or boot out of the original lasted shape. With the present invention the shank of a cowboy boot or high-arch shoe can be pressed without losing any of its original shape. It can be used also for cementing toe tips on boots or shoes, as well as the shanks of half soles.

The present invention uses a conventional last jack" and conventional shoe lasts; therefore, only the operating mechanism and accessories therefor are necessary to repair various shoes 9 and boots. No additional space is required for special stands, thereby saving the cost of the stand and special lasts. One stand may be used for a number of presses, because, after the shank or patch is properly placed in the press and the pressure applied, the entire press unit may be lifted from the last jack and hung up or laid out of the way until the cement dries, thereby saving additional stands or jacks. By properly cementing the sole to the shank of a shoe or boot it is substantially as smooth as the original sole; this can be accomplished only by the correct pressure at the right points; this press is so designed to give this pressure. A shoe or boot that has an invisible half sole joint will not hang on edges such as a clutch pedal, in a saddle stirrup, on a foot scraper, etc., to cause accidents. I

Any portion of an upper of a boot or boot leg can be patched with an attachment in connection with this invention, by shifting the boot about on the last which may vary in shape to suit the work being done.

The preferred embodiments of the invention are shown in the accompanying drawings, in whichm w 5 Fig. 1 is a side elevation of the invention asapplied to a conventional jack;

Fig. 2 is a front elevation thereof, at right angles to Fig. 1; I r r l Fig. 3 is a plan view of the lever, removed;

Fig. 7 is a viewsimilar to Fig. 6 but with the last rotated through 60 for patching a side of a boot or shoe; and

Fig. 8 is a rear view of a pad used to hold the patches in place until the cement dries.

With more detailed reference to the drawings, the numeral I represents a conventional stand or jack such as is used by shoe-makers and re: pairmen. The top of the stand I is tapered at 2 to receive an arm 3, in-this invention, which arm has a socket 4 on the lower side thereof, and a tapered top 5 on the upper side to receive a conventional last 6. The arm. 3 projects downward from the top of the stand, and terminates in a curved hook I. A bifurcated lever 8 embraces the hook 1, and has rollers 9 and i0 between the arms thereof to act as anti-friction" bearings against the respective outer and inner sides of the hook I at spaced points. Pins H and I2 in opposing relation with the respective rollers 9 and 10 on opposite sides of the hook I, hold the lever in guided relation at spaced points betweena. roller and pinrespectively- A bracket I3 is fixed to the lever B and projects upwardly therefrom. The bracket l3 has pins I4 projecting laterally-from aside thereof to engage selectively a loop I5 which passes over a resilient pad l6. 1 a

The resilient pad 16 has an upper metallic facing I! thereon with a longitudinal rib l8, notched at I9, for selective engagement with the loop l5 and to permit adjustment of the loop along the pad. metallic facing throughout a portion of the length of the facing, as by cementing or Vulcan.- izing, while the endof the facing llprojects in spaced relation from the pad; A secondary plate or metallic facing 20 extends partway of the length of the metallic facing l! and is directly below the projecting end thereof. The adhesion of the resilient pad l6 to both of the facings forms a hingable structure. A screw 2| threaded through the facing 11 against the plate 20, provides for an adjustment of'an end of the The resilient part It; issecured to the 2 pad Hi to conform to the approximate shape of the underside of the shoe or boot.

An edge of the hook I has ratchet teeth 22 to receive a pawl 23 pivotally mounted on the lever B, to hold the lever 8 in a fixed relation to the hook I, and also to hold a tension on loop which applies the pressing action to pad H5.

Figs. 1 and 2 show the press in operative condition, with a shoe S on the last'fi. A half-sole is shown applied to the shoe, and the pressis applying pressure to the shank B of the shoe where the sole is beveled to a thin edge and coated with,

cement. Due to the quick dry ngv qualitiesofthe leather cement used in cementing'the shanks of soles to shoes, screw presses are too slow and per mit the cement to become too dry before pressure can be applied. With this invention, the pad 16 can be adjusted at 2| to conform to peculiarities of the shoe arch; then the loop side and the cement applied. The pad I6 is then put in place quickly; the loop I5 engaged with a notch l9 and thelever 8 pushed downward where it is locked by the pawl 23 engaging a ratchet tooth 22, applying correct pressure to the loop lli and the pad l6.

After this pressure is applied, the unit may be removed from the stand without lessening the pressure, and either hung up or laid aside until the cement has dried and set securely. This will enable the use of the stand or jackifor other work or pressing actions.

The pins l4 provide l5 with respect to the work. The rollers 9 and Hi serve to lessen friction as the pressure is applied by the lever 8. The bracket I3 is affixed to the lever 8 (Figs. 2 and 5) in such manner that, as the lever moves around the arcuate hook I counter-clockwise, the pins H and I2 will de's'cribe a movement to the left, and the 'combined move ments thereof will apply substantially a straightline movement to the loop l5 within the average working limits of the press. The straightdine movement is desirable inasmuch as even pressure is applied thereby to the shank while it is being cemented. f T Y The lasts used with this press are conventional or standard lasts such as arefound at the average shoe repair shop; therefore, no special'lasts are required to cement the shanks of boots or shoes. The application of the invention shown ings; 4 to 8 inclusive is for use in'patching toe caps, uppers of shoes or boots, and boot legs. The pressure applying mechanism is the same as described above, but instead of the conventional last 6, a lasting frame 24, of U-shape is used, one arm of which has a tapered recess similar to that of the last 6 to fit on the top tapered portion 5 of the arm 3. The last-mentioned arm is. offset at its lower end and projects upward, across and downward so that its other arm is approximately in axial alignment with-the-stand or jack I, as shown in Fig. 5. The lower end of the last-mentioned arm is turned outward to form a stub 26,

' shown as of hexagonal shape, to receive a toe-,

shaped last 2'! fitted thereon in an upright position. However, the last can be adjusted to six positions with this shape of stub, asmay be'seen in Figs. 6 and '7. The extended frame 24 permits a high top boot to be inserted in upright position, as shown in Figs. 4 and 5, and repairs made on the toe cap or upper, such as the patch P.

A pad 28 is used, similar to the pad 'I 6, but has three adjusting screws 29 so as to conform both sides and the end of the resilient pad to fit the toe of a boot or shoe or any other 'portionbeihg re for adjust-ability of the" loop [5 swung to. one

"portion that requires patching;

paired. The toe last 21 when placed in position on the hexagonal stub 26 will occupy approximately the same level as the top of the last 6 when on the arm 3; therefore, one pressure mechanism can be interchangeable on either last. It will be readily appreciated that last 21 can be tilted from side to side as shown in Fig. '7, to patch any portion of the toe or upper of a shoe or boot.

. In'the operation of thedevice, the toe last 2': is placed on the'hexagonal stub 25 o'fthe frame 24, and the boot or shoe pulled on in upright position with the high inverted U-shaped member 24 permitting boots of any height to be accom- The patch P is applied to the particular loop i5 is swung over the pad 28, and the pressure applied by lever While shown to adjust the plates of the v I be understood that other means, such as wedges or the like, may be used if desired.

The recess 25' on the frame 24 is so constructed that the lasting frame 24 can be set at different lateral angles relative to the stand I, thus turning the toe last 21 to different positions relative to said stand.

In the forms modated.

set sorews'are pad 28, it will of the invention illustrated, the arm 3 and loop [5, are shown long enough to accommodate a boot, as well as a shoe, but it will be evident that for patchingonly shoes, these may be shortened to the desired extent, moving the adjusting means to a higher point relative to the last.

- While reference is made herein to the, application of a patch to a boot or shoe, it is intended that this should apply to any repair patch that is secured to the boot or shoe, whether on the upper, the tip, or the sole or half-sole. 'Moreover, the pressmay be used' for cementing the various parts of a shoe together during the manufacture thereof, as well as for repair.
