Specification of Letters Patent.

Patented May 9, 1916.

. Application filed July 11, 1912. Serial No. 708,908.

To all whom it may concern Be it known thatI,MIo1-IAnL FRANK Bno-.

GAN, a citizen of the UnitedStates, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain Improvements inivVork-Suppmts, of

which the following description, in 'connec tion with the accompanying drawings, isa specificatlon, like reference characters on the drawings indicating like parts'in the several figures.

This invention relates to i work' supports for holding boots and shoes in position to be operated "by shoe machines and is herein shown and described by way of exemplification as particularly adapted for 'support-,. ing shoes for the operation of aheelbreasting machine. 7 a j, r

The heel breastlng operation consists n removing the surplus material from the front face'orb'reast of the shoe heeland is generally performed by a machlne having a knife mounted for vertical reciprocation, the

transverse center of the heel portionlof the last but is displaoedto one sidein a right last and to the'other sidein a left last. It is accordingly necessary to provide lateral movement of the last relatively to the knife so as tobringthe center of the knife to the center of the heel. In some styles of heels,

moreover, particularly high heels, it is usual' to make the. angle'between thebreast and shank somewhat acute and to efiect this re sult the forepart 'of'the shoe iselevated-to' locate the' heel at the proper angle to the knife, theylast'being so mounted asto permitthis movement. It is found, however,

when high heels are placedat a great inw,

clinationv to, the knife the line of pressure exertedby the knife is apt to fall to the rear of the transverse; axisabout which the shoe is, tilted, thereby causing the "forepart ofthe shoe tof rise with consequent failure of the breasting operation and liability of injury, to the heel.

. It'is-the object fthis invention to pro vide a last pin mounting for a work support which, while compact enoughto enter 'means for turning the worm tohadjust the the smallest shoe, will provide the necescenter'of tl1ebreast to the center of the knife, and also allow movements of the shoe 1n a vertical plane to enable any desired inclinationlto be given to the breast face relatively t the trade'face of the heel.

- An important feature of the invention consists in aflast pin which is mounted on a support for movement in a vertical plane about a transverse located adjacentto the lower end of the last pin, that is, ap proximately at the crownof the last. For

this purpose the support comprises two parts connected by asegmental guide and NEXV' JERSEY, A CORPORATION: OF

This construo' tion'enables the pin to be placed at various anglesto thepla'ne of the knife so that the breast face may be given any desired inclif nation relatively to the tread face of the heel, and obviates any danger of the line of aotionjof the. knife falling back ofithe.

The construction of the mounting. is so compact that the top or leg of a small shoe may be placed over it in-putting thelast upon the last 7 pin. As shown, the last pin mounting consists'of a base adapted to be so i Another feature of theinventionconsists secured to a jackpost or. other support, (a.

last pin carrier, and an intermediate I section located betwo n fi Carrier andthe with the accompanying drawings, and will be pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of thework support with the breasting knife shown in dotted lines;'Fig. 2 is a central section of the devicepartly in elevation;

Fig. 3 is a similar View of a modification. The herein shown embodiment of'the invention comprises a base portion 2 which is adapted to be clamped upon the upper end of a jack post by a set screw In the upper end of the base 2 a T-shapedguldeway 6 is formed which is arranged to extend in the direction of the knifeedge, indicated' at w, Fig.1. In the T-shaped guideway of the base 2 is fitted a T-shaped guide 8 upon an intermediate section 10. A notch is made in oneside of one of the ribs of the T-shaped guide 8 to receive the end ofa set screw 12. which limits the movement of the guide 8 inthe base 2 and may be re moved when the parts are to be detached.

The intermediate section lO'comprises two.

portions or'blocks 14 and 16' which are connected together by a -T-shaped segmental I guide 22 and corresponding 'guidewayi'20,

the guide 22 being upon the upper portion 14 of the intermediate section 10. The movement of the guide 22 in the guideway 20 is limited'by a set screw 24 in a manner similar to that already described for thestraight guide 8. In the upper portion 14' of the intermediatesection 10 is a second straight T-shaped guideway 26 which Is arranged in the'same direction as the guideso that theaxis of the cylindrical hole in the way 6, and a T-shaped guide 28 formed on a block 25' which constitutes the carrier of a last pin 32 is arranged'toslide freely in said guideway; Movement ofthe carrierfguide 28 in its guideway'is limited by a, set screw 30 which'enters a notch in the last pin carrier guide .28. 'The last pin 32-is securedin the carrier 25 and at its lower end with regard'to its exposed portion is a collar 34, upon which the end of I the last thimble or the crown of the, last rests when'the last is placed on the pin. The last pin 32 is tapered and is somewhat smaller than the hole in the thimble of the ordinary last. This looseness is p rovided thimble need not coincide'exactly withfthe axis of the pin, and the convex upper face of a collar 34 serves to support the end of the thimble with the axis of the thimble at varying inclinations to the axis of the pin.

In use, the base 2 having been secured firmly to the jack post with the straight slides extending transversely of the shoe or in the direction of the plane of the knife, the shoe is placed upon the last pin or spindle and the jack swung under the operating parts of the breasting or other machine. As the thimble of the last is not usuallv in the center of the heel portion of the last, that is, is not under the center of the heel seat, the shoe may be moved laterally by reason of the straight guides until the'center of the heel is opposite the center of the operating instrumentalities of the machine, as for example the presser plate and knife of the heelbreasting machine; The shoe may be tilted vertically about the axis y of the segmental guide which axis lies approximately-at the crown of the last until the breast is at the proper inclination to the knife or operating means. The center of movement of'the segmental guide is also approximately at the base of the last pin, and therefore, it is practically im- 7 possible to incline the shoe to such a degree as to throw the line of pressure of the knife back of the axis of the segmental guide. If desired, the segmental guide may be fixed at any inclination by means of a set screw 36, Fig. '2.

In order to permit ready adjustment of the angle of theheel pin'onthe segmental guidewayl the modification shown in Fig. 3 mayfb'eemployed in which the lower face of the segmental guide 22 is formed with worm teeth and a worm 38"is journaled'in the lower portion 16"of the intermediate section 10 in a position to engage the teeth on the segmental guide. The worm is provided with a thumb head 40 by which it may be readily turned to adjust the inclination of the last pin 32.

Having described my invention, What I claim asnew and desire to secure by'Let ters Patent of the United'States is i '1. In a last pin mounting for shoe supports, the combination with a base of a last pin carrier, a last pin mounted thereon, and
