LAST-SUPPORT.

T0 a'l'l'whom it may concern:

.Be 'it known that we, JOHN M. MADIGAN and DANIEL C. 'SMI H, citi 2ens of the Unit ed and residents of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new" and useful Improvements in Last-Supports,

of which the following is a specification.

This invention relates to supports for lasts and has for its object the provision of a support of this character in which lasts of various sizes and shapes may 'besupported while transverse holes are bored therethrough.

The invention consists in certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a plan of a device embodying the principles of the present invention. Fig. 2 represents an elevation of the same, showing a last supported therein, said last being out in section, and Fig. 3 represents a transverse sec.- tion of the same with the last removed, the cutting plane being on line 3-3 on Fig.2 of the drawings.

Similar characters designate like parts throughout the several figures of the drawm s.

in the drawings, 10 is the base of a frame having an upwardly extending back plate 11 from which forwardly extends the ribs 12 having alined bearings 13 in the front ends thereof. On the rear face of the plate 11 are rearwardly extending inclined flanges 14: forming a guideway for the slide 15, the upper end of which has secured thereto a forwardly extending plate 16. This plate 16 has in its under face a dove-tailed groove 17 in which is mounted a perforated plate 18 adapted to be adjusted longitudinally of said groove 17 by means ,of the adjusting device 19. This adjusting device 19 consists of a threaded member 20 freely revoluble in the lug 21 extending upwardly from the plate 16 and prevented from endwise movement by the collars 22 thereon. The threaded portion of the member 20 engages with the lug 23 extending upwardly from the perforated plate 18. The plate 18 is provided with a plurality of openings 24: extending therethrough, these openings being disposed relatively to each other in the Specification of Letters Patent.

same position that it is desired tobore a plurality of holes transversely of the last 25 The upwardly extending back plate 11 secured thereto a forwardly extending spin,- dle 26 adapted to enter a hole 27 bored upwardly from the bottom of the last to a point near the top thereof, the end of said hole 27 bearing against the outer end of the spindle when placed thereon. When the last 25 is placed upon the spindle 27 the forked members 28 and 29 are adjusted so as to straddle the comb and heel of the last respectively. These members 28 and 29 are pivotally mounted in the forked ends of the sliding bars 30 and 31 respectively. The bars 30 and 31 are slidably mounted in grooves in the alined bearings 13 therefor. Each bearing 13 has secured to the rear of its upper face atop plate 32 through a slot in the front edge of which extends upwardly a threaded shank 33 secured to the front part ofsaidbearing 13. Above the top plate 32 and threaded to the shank 33 is the clamping nut 34 by which the top plate 32 maybe forced into contact with the upper face of one of the bars 30-31 to lock said bar in adjusted position.

To accommodate the device for various sizes and widths of lasts, the forwardly extending plate 16 may be adjusted vertically toward and from the spindle 26 by means of the adjusting member 35 having a reduced end 36 threaded to an ear 37 extending rearwardly from the back plate 11 into a recess 38 in the slide 15. By means of the various adjustments shown and described, any shape or size of last may be properly positioned by the spindle 26 and prevented from turning thereon while the frame is moving beneath the boring tool and holes 39 are bored transversely through the last 25 at the desired points. Preferably when the first hole 39 has been bored a pin of any well-known construction is inserted through the hole 24 into the hole previously bored, thereby serving as an additional means for preventing any displacement of the last while the remaining holes 39 are being bored and insuring that all of these holes 39 will be bored parallel to each other. This makes a very convenient last support to be used in boring transverse holes through the last, means being provided whereby the holes bored through the last may be properly disposed relative to the bot- 26 serving to register the last 25 y to the bottom of said base; a

I combination of a base;

understood from the foregoing description Having thus described our invention, We claim; i i

1. In a device ofthe class described, the

combination of a base; a last support supportedthereby, and parallel to the bottom thereof; av frame movable perpendicularly perforated plate slidably mounted on said means for adv described, the a pin supported by and parallel to the bottom of said base In a device of the class adapted to supporta last; a frame movable perpendicularly to the axis of saidpin; a perforated .plate slidably mounted. on said frame parallel with said last supporting pin; means for adjusting said perforated plate; and independently operated forked members on said frame for straddlingthe comb and heel of the last on said support.

I In a device of the class described, the combination of a .base; a

perforated plate slidably mounted on said frame parallel with said last supporting the supin adjusted other.

' 4. In a device of the class described, the

combination of abase; a last support therea 'on consisting of a pin parallel to the bottom frame parallel pin supported by; and parallel to the bottom of said base pin; means for adjusting said perforated plate; forked members on said frame for straddling the comb and heel of the last on said support; and means whereby said forked members may be adjusted and locked of said base; a frame movable perpendiciblarly to the axis of said pin; a -perforated plate slidably position independently of each' mounted on said frame aral lel With said last supporting pin; and means for locking said perforated plate in adjusted position. i

5. In a device combination of a on; a frame movable toward and from said base; a perforated plate slidably mounted on said frame parallel With said last support; means foradjusting said perforated plate; alined slidable members on said of the class described, the

frame; means for clamping said members in adjusted position; and forked members pivoted to said slidable straddle the comb and heel of the last.
