CHANNELlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 635,551, dated October 24, 1899.

' Application filed December 13, 1898. Serial No. 699,156. (No model.)

To all whom it may concern:

Be it known that we, JOHN KEATS, mechanical engineer, of Bagnall, near Stoke-on-Trent, in the county of Stafford, and WILLIAM STE- PHENS CLARK, boot manufacturer, of Street,

in the county of Somerset, England, have invented certain new and useful Improvements in Machinery for Channeling Boot or Shoe Soles, of which the following is a specification.

IO This invention relates to improved machinery for channeling boot and shoe soles for their conversion into ribbed soles by the molding and shaping machinery that forms the subject of a British patent granted to the r 5 present inventors and bearing date July 14, 1897, No. 16,720, and of an application, Serial No. 651,112, filed September 10, 1897, for Let ters Patent of the United States.

The chief feature of novelty in this invention consists in the tool-holder,which provides for such variations in the positions of the channeling-tool whenpresented to the work as will enable all the channeling operations required in bootmaking to be effected by the 2 5 aid of two tools instead of a special tool being needed for each variation of out.

In the accompanying drawings, Figure l is a side elevation of a channeling-machine with the improved tool-holder appliedthereto.

Fig. 2 is a sectional plan view on the line 00 at, Fig. 1; and Fig. 3 is a front elevation of the same. Fig. 4is a side view of the tool-holder detached from the machine, showing the tool in place and acting upon the leather. Fig. 5

5 is a plan view of the same, and Fig. 6 is a View taken at right angles to Fig. 4 and showing the tool in position. These three views are drawnto a somewhat larger scale than Figs. 1, 2, and 3. Figs. 7, 8, and 9 are dia- 0 grams illustrating the work designed to be produced by the channeling or cutting tools. Fig. 7 shows an angular cutter so set as to cut a channel for an outer sole, and Fig. 8 shows it as set for channeling an insole. Fig.

4.5 9 shows a gouge-shaped tool for chamfering the edge of a sole.

Referring now to Figs. 1, 2, and 3, A is the bed-plate of the machine; B, a standard cast in one with the bed-plate, which at its upper part is slotted verticallygto receive the forward end of a rocking frame 0. D D are a pair of standards, also cast solid with the bed-plate. These standards are fitted with fulcrum-pins (l, which serve to connect the frame 0 with the standards. In this rocking frame is mounted a shaft 0, which carries a pressing and feeding wheel 0 E is a horizontal 1ongitudinal shaft having its front bearing in the standard B and its rear bearing in a block A,castwiththebed-plateA. Mountedloosely on the rear end of this shaft E is a handwheel E, which carries on its boss a spur-pinion E gearing with aspur-wheel C keyed to'the shaft C. It is by turning the hand- Wheel E that rotary motion is imparted to the shaft Cof the rocking frame and consequently to the feed-wheel O Keyed to the shaft 0 Within the rocking frame 0 is a spur-wheel e, which gears intoa spurwheel a of like diameter keyed onto the shaft E, and it is through these spur-wheels that rotary motion is imparted from the shaft 0 to the shaft E.

The forward end of the shaft E carries a bevel pinion e for transmitting motion through a bevel-pinion f, keyed on an inclined 7 5 shaft F, which carries at its upper end a con ed feed-wheel F. This coned wheel is situated immediately below the feed-wheel C and is intended to support in a horizontal position and carry forward the work to be presented to the cutting-took The inclined shaftF turns in a bearing formedin a cranked bracket-piece B',projecting from the standard B. The horizontal portion of this bracket is bored vertically to form a socket for the stem of the toolholder, which may be described as a compound tool-holder, consisting of two parts G and G, the one part G serving to secure the. vertical adjustment of the cutting-tool, and the other G the lateral and angular positions of the cutting-tool, which is situate close to the feed-wheels and in line with the bite thereof.

9 is the stem of the part Gr, fitting in the socket formed for it in the bracket projection B and capable of vertical adj ustment therein. The lower extremity of the stem is notched to receive the end of athumb-lever g, fulcrumed under the cutting-tool.

on the standard 13 and serving to lift the holder G to any desired elevation. To secure the stem in its adjusted position, a clampingscrew g is provided.

The part G of the tool-holder is L-shaped in plan view. It consists of a rounded stem, which passes through a horizontal socket formed in the block G and carrying a squaresocketed arm for holding the tool The rounded stem'is threaded at its extremity to receive a biuding nut g, which draws the socketed arm into contact with the part G and holds the part G firmly in position.

For the purpose of adjusting the inclination of the tool g with exactness the rounded stem is provided with worm-teeth 9 into which takes a worm g. The worm-spindle fits in a vertical socket made in the part G and carries at its upper end a milled head for turning it when it is required to impart an axial motion to the stem G. By this means the angle of inclination of the tool g (in the socketed arm) is determined, the nut g being slackened for the purpose. hen the exact adjustment is obtained, it is secured by tightening up the nut g", and thereby drawing the socketed arm tightly against the block G.

The tool g fitting in the socket of the square part G, carries on its stem rack-teeth, into which gears a spur-pinion g carried by a spindle g fitted with a milled head for turning it. Access for the pinion to the teeth of the tool-stem is given by boring a hole transversely through the square-socketed limb of the part G, and by turning this pinion an endwise motion is imparted to the tool to bring it into position for channeling the work.

lVhen properly adjusted, the tool is secured in its squared socket by a clamping-screw 9 From the above description it will be understood that the cutting-tool holder is not only adjustable vertically to adapt the tool to its work, but that the tool itself is capable of being shifted in its socket with the greatest nicety to secure a determined depth of incision in the edge of the work.

Afixed guide is provided to enable the workman to secure the work in the proper position for the cutting-tool.

On the bracket projection B is fixed a small bracket H, which carries at one side an L- shaped piece It. The face of this piece 7L receives the thrust of the work and forms the guide for the workman to traverse the work This guide is situate in rear of the bite of the rollers, and abreast of it is apresser, to be now described. Pivoted to the upper part of the bracket H is a rock-lever I, the forward limb of which constitutes a presser-foot for holding down the work on the coned feed-wheel F independently of the bite of the top feed-wheel C 1: is a coiled spring, which is mounted on an adjustable screwed stem 1", fitted to the bracket 11. This stem carries a milled collar, and upon this collar the coiled spring 2' rests. For adjusting the pressure of the spring on the presser-lever I the screwed stem 2" is turned in its threaded support by means of the milled collar, which will enforce or slacken the force of the spring, as desired. The tail of the presser-lever serves both for lifting the presser out of action and controlling its action on the work.

To provide for the proper grip of the work by the feed-wheels, a treadle action (indicated by the pressing-lever O and its pendent rod 0 is applied to the rocking frame G and, bearing down that frame, holds the upper feed-wheel (J in close contact with the work. On the release of the rocking framefrom the action of the treadle the upper feed-Wheel is raised from the work by the tension of a coiled spring C, attached to the .base A, and to a rock-lever G fulerumed to the standard B and underlying the rocking frame.

It may be here remarked that in order to prevent the disengagement of the gear-wheels e and 6' when the frame 0 is rocked the pivot (Z of the latter is arranged in line with the point of engagement of the said wheels, as seen in Fig. 1.

The working of the machine may be thus described: Supposingit is desired to channel a sole in the manner illustrated in Fig. 7, for example,the cutting-tool is adjusted and secured in the position of that figure, and the upper feed-wheel being in the dotted position of Fig. l by reason of the drag of the spring (J on the lifting-lever (J the attendant places on the conical periphery of the lower and inclin ed feed-wheel F the sole to be channeled, passing it under the presser I and against the guide 72, which insures its proper lateral position in the machine. He then by the treadle device presses down the feed-wheel 0 onto the work and turns the hand-wheel E to impart rotary motion to the feedheels, maintaining at the same time with his foot the pressure of the feed-wheel O on the work. The sole will thus be caused to pass under the action of the fixed cutting-tool g which will gouge out an angular piece from the flesh edge of the leather and at the same time make a slight undercut in the leather at the angle of the channel. As this operation is proceeding the attendant will keep the work in contact with the guide It and so manipulate it that the cut of the fixed tool will follow the shape of the sole, forming a channel all around it, and thus prepare the sole for the action of the rib-molding machine above referred to.

It maybe here remarked that the machine, although designed for a special purpose, is applicable to the channeling of soles generally, and when fitted with a suitable tool, such as that shown at Fig. 9, it may be used tolchamfer oif the sharp angle of the outer so es.

said Worm-teeth, all substantially as herein described.
