EDGE-FINISHING MACHINE.

SPECIFICATION forming part of Reissued Letters Patent No. 11,580, dated'D'ecember 29,1896. Original 9, dated September-l, 1896. Application for reissue filed October 21,1896. Serial No. 609,625.

To all whom it may concern:

Pe it known that I, SETH D. TRIPP, of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in Edge-Finishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates to edge-finishing machines adapted for finishing the edges of the soles of boots and shoes. In machines of this the shoe-sole.

class the ed ge-finishing tools have been moved back and forth, as, for instance, they have been oscillated or reci'procated. For the production of good work it is necessary tooscillate or reciprocate the edge-finishing tool very rapidly, and when the tool is so driven it will vibrate or jar the shoe and consequently the hands and arms of the operator holding it, such action. being due, mainly, on account of the irregular form or curvature of This invention has for its sists in giving to an oscillating edge-finishing tool or one moving rapidly back and forth an independent back and forth movement, so that it will advance or move along the work in each direction as it oscillates.

In carrying out this invention I provide a frame and means for moving it rapidly back and forth, and upon said frame I mount the edge-finishing tool and provide means for moving said tool back and forth in unison with the frame. The tool will preferably be moved back and forth in the are of a circle, while the frame carrying it may be vibrated or moved back and forth in any desirable manner, so long as the parts operate in unison.

The tool maynot only be oscillated in unison with the back-and-forth movement of the object to very materially reduce this vibration or jar inci dent to rapidly operating the tool in the manner above referred to; and the invention contoOl is provided with a plurality of working faces, and means are provided for adjusting said tool While in operation to bring any one of its Working faces into working position. A friction heating device is provided for the edge-finishing tool which comprises frictionplates bearing directly against the opposite sides of the tool, meansbein'g provided for holding said platesin such frictionalengage ment. The shaft carrying the edge-finishing tool is adapted to be raised or to yield in a vertical direction, and the tool is alsoadapted to yield in a longitudinal direction on the shaft'whieh carries it.

Figure 1 shows in side elevation an edgefinishing machine embodying this invention; Fig. 2, a right-hand cndelevation of the same, the friction heating device being removed; Fig. 3, a vertical section of the machine, taken 011 the dotted line a" .2", Fig. 1; Fig. 4, adetail to be referred to.

The main frame A is of suitable construction to support the operating parts. The main shaft (4 has its hearings in said frame, and has a driving-pulley a mounted upon it. Formed upon the end of the shaft or is acrank-pin or eccentric a which receives upon it a boxe The cran k-pin is free to rotate in the boa, but as it turns said box is moved to corr pond with the travel of the crank-pin. The box a is fitted to work within the bifurcated upper end a of a pivoted arm a as, forinstanee,it may project from a sleeve a placed upon a stud or rod a, which serves as a pivot on which said arm vibrates The sleeve a 'has depending from it a frame b, which serves as a bearing'or support for the bearing-box b, which is bored to receive a shaft 11 The bearin box 1). and shaft b are arranged obliquely,

and the rear end of said shaft 1) has formed in it a socket'which receives a spherical stud 2, secured to a rearwardl'y-projecting portion of the frame I A spring 3 is interposed beit is desired to raise the edge-finishing tool 0,

which is placed upon the shaft. The edgefinishing tool 0- is made as a hub adapted to be placed upon the forward end of said shaft 0, bearing against a washer-b also placed too tool at the opposite side, serve as a friction 7 into working position, and to accomplish this .tor'also enable another tion to be performed, namely, to oscillate the tool'carrying shaft on acts to permit the edge-finishing tool to yield is obvious that oscillatory motion, for it will be seen that as the toothed sector is held at rest whenever on said shaft, which latter in turn bears l against a spring I), likewise placed upon the shaft and next to the front end of the bearin g-box b, so that said spring is interposed between the bearing-box b and the washer and longitudinally on the shaft. The edge-finishing tool is splined onto the shaft 1) and is thereby permittedto move longitudinally thereon. A washerd is placed on the shaft b next to and bearing against said edge-finishing tool, and a strong flat spring-e is attached to the red a which is bent more or less U-shapediand provided with a bifurcated end 6', which embraces the shaft 11 and bears upon the washer d. The washers b and d are held from turnin with the shaft, and for simplicity there may be a pin lO on the depending arm, which projects from and enters a slot formed in the washer b and a pin 12 on the Washer d, which projects forward and enters a slot in the fiat spring. The spring 2, bearing against the washer d at one side of the edge-finishing tool, and the washer b bearingagainst the edge-finishing heating device. As the main shaft arevolves the arm a is vibrated; oscillating the sleeve 01. on the rod a and correspondingly oscillating the depending frame b, and consequently the edge-finishing tool. The edge-finishing tool thus moves back and forth in the arc of a. cir-' ele about the rod a as a center.

The edge-finishingtool has a plurality of workingfaces, it "being herein represented as having four, each differently formed, yet it I it may have as many as desired. In practice it is frequently necessary to adjust said edge-finishing tool whileit is operating to bring a different working face result a toothed gear f is'secured to the toolcarrying shaft 6*, which is engaged by a toothed sector f, mounted on rod 0. and prov ded with a hand-lever f by means of which it may be turned on its pivot. A quadrant 1 1s fixed to the main frame, having as many notches as there are working faces on the edge-finishing tool, and the hand-lever has a lockmg-detent adapted to enter-any one of the notches and thereby hold the pivoted sector in different positions. -It will be seen that by disengaging the locking-detent-and turning the pivot-ed sector the toothed gear will be rotated to turn the tool-carrying shaft, and consequently the tool which 'is splined thereon. This adjustment may be made while the edge-finishing tool is in operation, notwithstanding it may be operating very rapidly. The toothed gear and toothed seemost important funcits axis, and consequently impart to the edge-finishing tool an the frame 12, carrying the tool-carrying shaft,

oscillates in one direction the toothed gear will be rotated one way, and as the framcoscillates in the opposite direction the toothed gear will be rotated in the opposite way. Thus it will be seen that the edge-finishing tool has an oscillating movement on its own axis in addition to the vibratory or oscillatory movement of the frame carrying it, and as a consequence the edge-finishing tool will act or work upon the sole edge as it is bodily moved in each direction along said sole edge, thus having a compound vibratory movement. It will also be seen that, as herein shown, the back-and-forth movements or oscillations of the tool are in unison with the back-and-fortlr movements of the frame carrying it and also in a like direction. The pivoted sector instead of being utilized as a cooperative part'of the group of mechanism adapted to perform the double function above set forth may be secured permanently to the frame and the hand-lever andlocking devices omitted, in which case the edge-finishing tool will be oscillated as the frame oscillates; but it cannot be adjusted to present different working faces into working position. \Vith a machine constructed in this latter way the edge-finishing too], if provided with a plurah ity of working faces, may be adjusted in any well-known way. I I desire it to be understood that I do not 'wish to limit my invention to the particular means herein shown for imparting independent oscillatory motion to the oscillating tool, and, furthermore, believing myself to be the first to provide angedge-finishing machine with a tool-carrying frame and means for moving it back and forth or oscillating. it and providing means for moving the tool carried by said frame back and forth or oscil lating it independently of but innnison with the back-and-forth movements of the frame I desire it to be understood that such features come within-the spirit and scope of this 'invention.
