MACHINE FOR BEVELING- BOOT-FORMS.

Specification of Letters Patent No. 1,716, dated August 12, 1840.

Be it known that I, ELIJAH HOLMES, of Stoughton, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Machinery for Forming the Beveled Edges of Boot-Forms.

These improvements, the principles thereof, the manner in which I have contemplated the application of said principles by which it may be distinguished from other inventions, together with such parts or combinations I claim as my invention and hold to be original and new I have herein set forth and described, which description taken in connection with the accompanying drawings herein referred to composes my specification.

The manner in which the common boot form is shaped is understood by all persons conversant with the same, but in order that the object of my machinery may be fully comprehended by others, it must be borne in mind, that the common boot form is a piece of board on which the leather of the front of a boot is strained and shaped, so as to give the foot its proper position or angle with respect to the leg, previous to applying the same to the last; this has generally been done by the hand and tool of the workman, and the peculiar oiiice of my invention is to accomplish the same by my improvements, with a great saving of time, labor and expense, and in as perfect if not a more perfect and regular manner t-han that hereto-fore practiced.

Figure l, is an end elevat-ion of my machinery. Fig. 2, being a plan of the same with the beam A A removed, or a horizontal section in the line A A.

The framework B B B B is sufficiently represented in the two figures to show the manner in which the operative parts 0f the machinery are supported.

A perpendicular shaft pp has a pulley s firmly attached thereto as seen in Fig. 1, to which pulley a band from any driving power will communicate a rotary motionv also to said shaft and likewise to the parts connected to the same. Two circular frames m m a n are properly arranged on the vertical shaft p p, the said shaft being supported in any manner at its top, while the lower end rests and revolves in the step q attached to the cross beam B B. Planing irons la l Figs. l and 2 are arranged respectively in the circular planes or frames fm m n a. The frames m fm, a n are beveled f to be readily adjusted to anyrequired position.

a, o, Figs. l and 2 is the boot form in its rough state the inner edges of which are to be beveled by my improved machinery. This form is placed in a movable frame o b Fig. 2. This frame in shape is similar to the back and lower part of 'the foot of the form. Vhen the vform a a is placed in the frame b b, it is secured by the clamping screw d at the head of the same which presses it against the short points or teeth c, c at the foot o-f the frame. Their joint operation to produce the intended effeet will lbe ,readily understood without 'further explanation. The frame o b has two guides e, e, proj ect-ing downward as represented in Fig. l, and entering and working in the grooves a', b, c, CZ', e, f, g, it shown in Fig. 2. The guides e, e may be adjusted to dierent positions in slots 7L h Fig. 2, by means of the clamping nuts and screws formed thereon, as shown at z' z' Figs. l and 2, and more particularly in Fig. 3, whe-re it will be perceived that the project-ion or guide e has a shoulder c" against which the nut 7c operates 'when screwed down, so as to conline the guide or projection c in any position in the slot 7a; the lower part of the said slot being formed or cut larger than the upper so as to receive the shoulder, whose lower side is thus brought on a level or coincides with the under surfa-ce of t-he frame b Z). The object of the slots i, L is to enable us to slightly Vchange the position of the form a o with respect to the cutters, should the same at any time be deemed necessary.

From the machinery which has been above described, it will readily be seen, that when the form a a, is placed in the frame o b,-

and the whole is carried forward, toward the planing machiery, that the upper part of the edge, or toe of the foot of the form,

will lirst come in contact with the cuttersV and be beveled on each side, or formed of a Wedge shape which Ashape will correspond or fit into the opening formed by and between the frames fm, m, 'n n. On pushing the form forward, the cutters Will reduce the Whole of the upper edge of the foot, from the toe to the instep, and then on moving' the frame Z2 blaterally or so as to cause the guides e, e to travel in the portions o c, f', gr, of the grooves, the front of the leg of the form will be similarly reduced or beveled. These operations, being completed the frame Z) I) is Withdrawn or moved back,

- the guides e, e passing through the portions c', clv, g', /Lfof the grooves.

The position of the grinding grooves a, b', 0', al, e', f', g', li may be `easily obtained by passing the frame 7) (in which a `correctV pattern of the intended forni is placed and secured by the screw d), With the guides e, e attached thereto in the several directions necessary to Vgive the edges ofthe form, their proper beveling shape, or

so that the beveled edge of the pattern in the fframe `may be always pushed up, o-r held against the cutters, or between the plates or frames m m, n n during themotion of the frame b .b as aboverdescribed,

and the lines describedby the guides e, e or points or pencils substituted therefor,

Will denote the proper position on the board M of the grooves.

Having thus described my machinery, I

Vshall claim- Reducing or'beveling the edges of boot forms in the manner herein above ex- `twenty sixth day o-f .I une in the year 'of our Lord eighteen hundred and forty. y

ELIJAI-I HOLMES.
