SIMON ROSS, OF CINCINNATI, OHIO.

SOLE-TRIMMING MACHINE.

SPECIFICATION forming part of Reissued Letters Patent No. 11,602, dated MayI 25, 1897. Original No. 472,399, dated April 5, 1892. Application for reissue led March 31,1894. Serial No. 505,981.

T all whom, it' may con/cern:

Beit known that I, SIMON ROSS, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sole-Trimmin g Machin es, of which the following is a specification.

One of the objects of my invention is to produce a machine that will trim or shape from what is known as blocked stock 7"a sole or tap to any predetermined size from a given pattern.

Another object of my invention is to clamp the stock and pattern together and arrange them in close relation with a pattern-guide supported in juxtaposition to the cutter, thereby preventing variation of the sole from the pattern, due to lateral strain or lost motion.

Another object of my invention is to provide a revoluble clamp and pattern mounted upon a shaft, which is turned and presented to the cutter by the operator, who varies the feed as the need of the stock requires.

Another object of my invention is to mount the guide on a shifting slide, so it can be adj usted to the different sizes required by means of an adj usting-screw,and a lever can be made use of when the amount of material is great enough to require two cuts.

The various features of my invention are fully set forth in the description of the accompanying drawings, making a part of this specication, in which'- Figure 1 is a side elevation of my improved sole trimming or shaping machine. Fig. 2 is a front elevation of the main frame and cutter. Fig. 3 is a front elevation of the jackframe. Fig. 4 is an enlarged top plan view, partly in section, of the cutter head and clamping device. Fig. 5 is an enlarged sectional elevation of the cutter-head and guide. Fig. 6 is a plan view of the pattern and spacing-plate. Fig. 7 is a section on line xx, Fig. 4. Fig. 8 is a sectional detail view. Fig. 9 is a perspective of the fence.

1 represents the bed-'plate of the machine; 2, the main frame, mounted thereon.

3 represents a blower; 4, a dust-tube.

5 represents the main driving-shaft; 6, the main driving-pulley. This main driving-pulley transmits power to pulleys 7 on the cutter-shaft S.

9 represents a second pulley mounted on the main shaft 5 and transmitting power by the belt 10 to the pulley on the blower-shaft 11.

A represents the cutter-head, mounted on shaft 8. The knives or bits may be of any well-known form of construction.

B represents a jack-frame provided with a sleeve 12, that journals on stud-shaft 13. (See Fig. 2.)

14 represents a driving-pulley on the main shaft 5, and 15 represents a loose pulley on the same shaft.

16 represents a table, on the bracket of which is loosely mounted a stud-shaft 17, so as to be capable of oscillating in its bearing.

O represents a fence-rod journaled on the stud-shaft 17, and O represents a stock-gage supported on said fence-rod.

The numeral 1S represents a pattern-gage which is adjustable radially to the axis of the pattern.

c represents a set-screw for adjusting both gages radially to the stock and pattern.

22 represents a set-screw for adjusting the gages vertically.

19 represents a set-screw for engaging the gages laterally to the pattern. The stockgage and the pattern-gage thus arranged are supported upon the main frame through the table 16 and form an element of said main frame. As thus arranged, the jack-frame B oscillates during operation between the cutter 7 and the stock and pattern gages O/ and 18.

23 represents a weight attached to a chain passing over the sheave 24, one end of said chain 25 being secured to the weight 23 and the other end secured to the j ack-frame. The weight normally draws the jack-frame forward to the cutter-shaft. It is held back by means of the catch-lever 26, the end of which engages on they stud 27 on the jack-frame.

D represents a grooved guide which journals in the sleeve 28. 29 represents a slide supporting said sleeve and gained into a guide-box 30.

31 represents a set-screw for adjusting the slide 29 to carry the guide D forward and backward for adjusting it to different sizes of work required.

a b represent collars on` the shank of the screw 3l to limit the forward-and-backward movement of the slide 29. It may be desired IOO to throw this guide forward at times in order to reduce the extent of cut when it is required to make two cuts instead of one in reducing the stock. This is accomplished by moving the shipping-lever 33 so as to spring the catch 34 in engagement with the lug 35 and thus hold the guide in its most advancedposition. Then the shippin g-lever is moved backward, the slide 29 is free to move backward.

E E represent clamping-heads. The clamp E is mounted upon the stud-shaft F, and the clamp E' is mounted upon the gudgeon I-I of a screwshaft G. The shaft G is screwthreaded through a split box I, supported upon the fork J of the jack-frame B.

K represents a sleeve supported on the fork L. This sleeve is screw-threaded through the boxing M, so that said sleeve may be adj usted longitudinally.

N represents a hand wheel secured to shaft F.

O represents a handle secured to the rim of the wheel andmay be operated to turn the said shaft and revolve the clamp-heads E E'.

R represents a spacing-plate provided with holes r s to pass over dowel-pins projecting from the clamping-head E. P represents a pattern provided with similar holes and placed between the spacing-plate R and the clamping-head E.

S represents stock clamped by the clamping-heads E E. This construction enables the clamping-heads E E to be used for various sizes of work, but the clamping-heads may be changed, if desired, as they are readily detachable from their supporting-gudgeons. The clamping-heads are driven by the hand-wheel N, which is turned by the operator to present the stock to the action of the cutter. Important advantages are obtained by this means, as the operator can turn the clamping-heads fast or slow, presenting the stock to the cutter no faster than it will reduce it. Thus if stock for the soles of a childs shoe is being reducedthere is much less stock to be cut away and it can be revolved faster; but if a large size-say the sole of a mans shoe-is to be reduced there is much more stock to be reduced, and it must travel a longer distance during the revolution and much more stock is taken off by the cutter, and a slower motion is required to avoid overfeeding. Another important advantage is obtained by arranging and clamping the pattern close up to the stock to be reduced and the guide close to the cutter-head and having the pattern and clamp supported on one and the same shaft and close together, as an accurate feed of successive charges of stock may be obtained, and they are trimmed to the exact size of the pattern P, which travels in the groove of the guide D, the guide being close to the cutter-head and the stock close to the pattern.

In Fig. 5 I have shown the guide D recessed out, so as to span the screw-head t, which clamps the cutters on the shaft 8. In order that the guide D may be readily moved out of the way to take off the cutter-head, I mount the guide-box 30 on the shaft 36, where it is held in position by the clamping- box 37, and 38 represents a clamping-screw which is loosened to allow the said guide-box to be turned up or down, relnoving the guide out of the path of the cutter-head. In order to set the screw-shaft G in a fixed position, it passes through the split box I, where it is secured in position by set-screw 39, so that said shaft G may be turned to clamp the heads E E and then set by the screw 39 to hold it in a fixed position. The clamping-head E forms the base on which the pattern P rests, and it must be adjusted exactly to the groove in guide D. This adjustment is secured by turning the sleeve K in box M, so as to move the clamping-head E and the pattern laterally to secure lthe alinement. The spacing-plate R keeps the pattern P a sufficient distance away from the cutter to prevent the pattern from interfering with the action of the cutter and allowing the inner edge of the stock to be completely trimmed down.
