SPECIFICATION forming part of Letters Patent N 0. 566,819, dated September 1, 1896.
Application filed January 10, 1896. Serial No. 574,941. (No model.)
To (0% whom it may concern: v
Be 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 accordance with this invention the edge-finishing tool is mounted upon an oscillating shaft, which is carried by an oscillating frame, so that the tool has imparted to it an oscillating movement on its own axis in addition to a Vibrating or oscillating movement on the axis of the frame carrying it. The edge-finishing tool 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 edgefinishing tool which comprises friction-plates bearing directly against the opposite sides of the tool, means being provided for holding said plates in such frictional engagement. The shaft carrying the edge-finishing tool is adapted to be raised, or to yield, in a vertical direction, and the tool is also adapted to yield in a longitudinal direction on the shaft which carries it.
Figure 1 shows in side elevation an edgefinishing machine embodying this invention; Fig. 2, a right-hand end elevation of the same, the friction heating device being removed; Fig. 3, avertical section of the machine, taken on the dotted line 00 to, Fig. 1; Fig. 4, a detail to be referred to.
The main frame A is of suitable construction to support the operating parts. The main shaft or has its bearings in said frame, and has a driving-pulley aniounted upon it. Formed upon the end of the shaft a is a crankpin or eccentric c which receives upon it a box a The crank-pin is free to rotate in the box, but as it turns said box is moved to correspond 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, for instance, it may project from a sleeve o placed upon a stud or rod a which serves as a pivot on which said arm vibrates. The sleeve cflhas depending from it a frame Z), which serves as a bearing or support for the bearing-box Z7", which is bored to receive a shaft b The bearing-box b and shaft b are arranged 0bliquely, and the rear end of said shaft 19 has formed in it a socket which receives a spherical stud 2, secured to a rearwa1dly-projecting portion of the frame I). A spring 3 is interposed between the bearing-box b and the sleeve a", the tendency of which is to depress said bearing-box and parts borne by it,yet permitting said box to yield in an upward direction when it is desired to raise the edge-finishing tool 0, which is placed upon the shaft. The edge-finishing tool 0 is made as a hub adapted to be placed upon the forward end of said shaft b bearin g against a washerb also placed on said shaft, which latter in turn bears against a spring 17 likewise placed upon the shaft and next to the front end of the bearing-box b, so that said spring is interposed between the bearing-box b and the Washer and acts to permit the edge finishing tool to yield longitudinally on the shaft. The ed ge-finishing tool is splined onto the shaft 11 and is thereby permitted to move longitudinally thereon. A washer d is placed on the shaft b next to and bearing against said edgefinishing tool, and a strong flat spring 6 is attached to the rod 0?, which is bent more or less U shaped and provided with a bifurcated end 6, which embraces the sh aft b and bearsupon the washer d. The washers Z7 and d are held from tu rnin g with the shaft, and for simplicity there may be a pin 10 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 flat spring. The spring e, bearing against the washer (Z at one side of the edge-finishing tool, and the washer b bearing against the edge-finishing tool at the opposite side, serve as a friction heating device. As the main shaft a revolves the arm (1. is vibrated, oscillating the sleeve (L on the rod a and correspondingly oscillating the depending frame b, and consequently the edgefinishing tool; The edge-finishing tool'thus travels'in the arc of a circle about the rod 06* as a center. The edge-finishing tool has a plurality of working faces, it being herein represented as having four, each differently formed, yet it is obvious that it may have as many desired. In practice it is frequently necessary to adjust said edge-finishing tool While it is operating to bring a different working face into working position, and to accomplish this result a toothed, gear f is secured to the tool-carrying shaft 27 which is engaged by a toothed sector f, mounted on rod a and provided with a hand-1everf by means of which it may be turned on its pivot. A quadrant f is fixed to the main frame, liavin g as many notches as there are working faces on the edge-finishing tool, and the hand-lever has a lockingdetent' 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 pivoted sector the toothed gear will be rotated to turn the tool-carrying shaft, and consequentlythe 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 sector also onable another most important function to be performed, namely, to oscillate the tool-car rying shaft on its axis, and consequently impart to the edge-finishing tool an oscillatory motion, for it will be seen that, as the toothed sector is held at rest whenever the frame Z), carrying the tool-carrying shaft, oscillates in one direction, the toothed gear Will be rotated one way, and as the frame oscillates 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 i to the Vibratory or oscillatory movement of 1 the frame carrying it. 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 and locking 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. 7 With a machine constructed in this latter way the edge.- finishing tool, if provided with a plurality of working faces, may be adjusted in any wellknown way. Therefore 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.
