little e orton the part of the operator of the machine.

With the foregoing in view, the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accom anying and forming part of thisspecificatlon, in which:

Fi re 1 is a plan view of' the machine constituting the best practical embodiment of my invention that I have as yet devised. Fig. 2 is an end elevation of the same. Fig.

3 is an elevation of one side of the machine.

Fig. 4: is a vertical cross-section, taken in the plane indicated by the line l-4= of Fig. 1, with the reciprocatory knife-carrier in position ready to-make its forward stroke. Fig. 5 is a detail transverse section showing.

by full lines a shoe clamped in proper position to have the forward portion of its outer sole cut off and the forward end of its rear portion'beveled. Fig. 6 is a detail, longitudinal vertical section illustrative of the means for transmitting motion from the driveshaft to the reciprocatory knife-carrier. Fig. 7 is a similar view showing a modified drive shaft and driving connection for reciprocating said carrier.

Referring by letter to the said drawings, and more particularly to Figs. 1 to 6 thereof: A is the main frame of the machine which is preferably in the form of a hollow stand, as shown. The said frame is provided adjacent, its upper end with a lateral worksupport B, having a detachable throat-plate B which, in turn, has a vertically-disposed slot 0 for the play of the beveling knife D, and also has a roughened upper surface E,

the latter to enable it to more securely hold the work against casual movement during the cutting and beveling operation. At the under side of its outer portion, the work supportv B is rovided with a transversely inclined guar F,-the office of which is to protect the insole and vamp portions of a shoe from the knife D by holding said portions away from the path of said knife. I

Movable vertically through suitable guide apertures a in the end portions of the work support B is a frame having. arallelxto bars G and also havin a depen mg stem guided in an arm J of the main frame,

Figs. 1-3, and arranged below and ivoted t0 the top bars G are clamping mem ers J disposed at opposite sides of the slot 0, and designed to hold a shoe sole against the roughened surface of the throat-plate B Springs K are interposed between the end portions of the clamping members and their respective top bars G, as best shown in Fig. 3, in order to yieldingly maintain said members J in a horizontal position and enable the same to better engage the sole to be clamped. The stem H of the vertically movable frame is connected in a swivel'ed manner to a plunger L, mounted in a stand M, and interposed between the upper end of the said stand and an enlargement on the plunger L is a coiled spring N which has for its function to return the verticallymovable frame and the clamping members J to the raised position illustrated A-foot lever P is fulcrumed on the stand M and connected to thelower end of the plunger L, and it will be readily' understood that when said lever P is depressed, the clamping members J will be depressed and held under pressure to securely hold a shoe sole between them and the throat plate B Suitably supported in the main frameAis the horizontal, reciprocatory knife-carrier R which has a lateral arm S extending through and movable in a slot T in one wall of the frame, and detachably fixed to the said arm S is a knife-holder U having an inclined socket V and a set screw W; the said socket being designed to receive the stem of the knife '1), and the set screw to bear a rainst and hold said stem. The under side of the throat plate B? at one side of the slot therein is beveledas shown to suit the inclination of the knife D; and the throat plate B and the knife holder U are preferably detachable as stated in order that they may be replaced with another throat-plate and another knife-holder according to the angle of the bevel that it is desired to prouce.

By preference both edges of the knife D are sharp, and hence it will be manifest that when a shoe is arranged as shownby full lines in Fig. 5, and they forwardportion of its outer sole is clamped between the clamping members J and the upper surface of the throat-plate B the said forward portion of the outer sole will, upon reciprocation of the knife-carrier R and knife D, be neatly cut off, and the edge left at the forward end of the rear portion of said sole will be neatl beveled to adapt it for the neat applicatlon' of a half-sole. It will also be readily understood that when the foot lever P is relieved of pressure, the coiled spring will raise the vertically-movable frame and the clamping members J, and the shoe may then be withdrawn from the worksupport B. p

For the purpose of reciprocating the knife-carrier R, the means lllustrated in Figs. 1 to 6, or any other suitable means may be employed without involving departure from the scope of my invention as claimed. The said means of Figs. 1 to 6 comprises a transverse shaft 0 journaled in the main frame A and having cranks d and -e and a clutch member f, a pulley g loosely mounted and movable sidewise on the shaft 0 and having a clutch portion complementary to the clutch member 7 and designed to be connected through a belt with a suitable motor (not shown), a vertically-swinging lever h fulcrumed at an intermediatepoint of its height in the frame A and having its lower arm connected with the crank d, and its up er arm connected with the carrier R, a roc -shaft 71 journaledin bearings at one side of the frame A and having arms j and 7c the latter of which is connected to the pulley g, and a spring l coiled about the rock-shaft i and arranged to normally hold the ulley 9 out of engagement with the clutch member 7. The spring Z normall holds the pulley 9 out of engagement wit the clutch member 7, and in this position of the parts the knife will be idle so that the work may be positioned and clam ed on the work-support B, in the manner efore described.

When the work is properly secured, the arm 7' is drawn toward the operator who stands at the pedal, whereupon the pulley y will be moved into engagement with the clutch member f, and the shaft 0 will be rotated and the knife-carrier R will be re-v ciprocated in the manner and for the pur- ,7 pose before stated. The crank e is provided upon theshaft c in order that .said shaft may, if desired, be operated byfoot-power through the medium of conventional or other means (not shown) connected to said crank.

In Fig..'?'. I show a modified means for reciprocating the knife-carrier R, which means comprises a shaft 0 having a pulley 9' and a crank cl, and a =pitman h interposed between and connecting? the-said crank and the carrier.

The constructions herein illustrated and described constitute the best practical embodiments of my invention of which I am cognizant, but it' is obvious that in the future practice of the invention such changes in the form, construction and relative arrangement of parts may be made as do not involve departure from the scope of my invention as defined in the claims appended.

Having described, my invention, What I claim and desire to secure by Letters-Patent, is:
