Definitions

  • My present application which is divided out from my pending application N o. 410,591 for Letters-Patent of the United States, relates to an apparatus for cutting 5 out tracks of a sine shape on aguide cylinder intended to guide rollers connectedto a reciprocating piston, so that when the rollers follow the sinetrack the reciprocation of the piston is transformed into rotation of a 19 shaft.
  • ⁇ A transformation of that kind vis more fully described in my" pending application No. 333,112 for Letters-Patent of the United States.
  • the object of the present invention is to obtain an apparatus adapted to-impart to each half of the guidecylinder above referred to such a motion in respect of a milling tool that a track of sine shape will be cut out therein.
  • Figure 1 is a vertical axial section of the apparatus supporting a half-cylinder.
  • Figure 2 is ahorizontal axial section of the apparatus turned by a quarter of a revolution in respect of the position of Figure 1.
  • the ⁇ half-cylinder a in which the upper L, or lower surface b, indifferently, of'thetrack o is to be cut out, is provided with two plates ⁇ c connected integrally with the base#1 of the halfecylinder by any means such as bolts (not shown). Between these plates rest the r camsl e eihaving a circular contour. Said cams are 'mounted eccentrically on ⁇ the axes tric cams e e in opposite directions., Said' v7c f' bearing the gearsfor the camscomprised, il:
  • the sleeve c is attached, on the one 99 hand, to the half cylinder a and, on the other hand, directly to the plate c and indirectly to the plate d by the intermediary of the base of the half-cylinder a 'as shown diagrammatically in Figure 2.l ,65, l
  • the central shaft j serves both to rotate the J half-cylinder a by means of the sleeve c and to guide said half-cylinder, whilel the track surface b is being cut out therein, by means of a shoulder m on the periphery ,of which 739 the cylinder will reciprocate.
  • rollers that guide the piston for the conversion of movement as described in my above y tively will occupythe same'po'sition as the milling tools in relation to the track.
  • An apparatus for cutting a sine track at the end of a guide cylinder comprising a vtool having a stationary axis and adapted to cut theI end portion of said cylinder, in combination with a rotary shaft adapted to rotate the cylinder about its axis, means for causing the cylinder to reciprocate on -said shaft, a ltoothed crown integral with said shaft, two
  • a machine for cutting a sinusoidalcam surface at the end of a cylindrical piece of work which comprises in combination, a bearing, an overhung shaft journalled in said bearing, means for causing saidpiece of work to rotate together with said shaft and allowing it to slide with respect to it, a toothed wheel keyed on said shaft between said bearing and said means, eccentric means, operaconnected with said toothed wheel, for reciprocating said piece of work with respect to said shaft synchronously with the rotary movement of said shaft, a tool havinga stationary axis disposed opposite the end of said piece of work, and means for driving said tool.
  • a machine for cutting a sinusoidal cam surface at the end of a c lindrical piece of work which comprises ⁇ in combination, .a bearing, an overhung shaft journalled in said bearing, a sleeve slidingly keyed to said shaft and adapted to rigidly support said iece of work, a' toothed wheel keyed to said shaft between said bearing and said sleeve, eccentric means, operatively connected with saidftoothed wheel, for-reciprocating said piece of work with respect to said shaft in synchronism with the rotary movement vof said shaft, a tool having a stationary axis of revolution disposed opposite the edge of said cylindrical piece of work, and means for driving said tool.
  • a machine for cutting asinusoidal'cam surface at the end of a cylindricalpiece of work which comprises in combination, a bearing, an overhung shaft j ournalled in said bearing, a sleeve slidingly keyed to said shaft and adapted to rigidly supportsaid piece of work, a toothed wheel keyed to vsaid shaft between said bearing and said sleeve, two cir-y cular rollers eccentrically pivoted about stationary axes means, operatively connected with said toothed wheel, for driving said rollers, a collar secured to said sleeve coaxially with, said shaft, another collar adapted to be fixed to said piece of work in parallel-relation with the first mentioned collar and at a distance therefrom equal to the diameter ofthe circlilar rollers, whereby said rollers are engaged between said collars and are able to cooperate therewith, a tool having a stationary axis of revolution disposed opposite the edge of said cylindrical piece of work, and means for driving said tool.
  • vA machine for cutting a sinusoidal cam surface at the end of 'a cylindrical piece of work which comprises in combination, a bearing, an 'overhung shaft journalled in said bearing, a sleeve slidingly keyed to said shaft at right angles to said shaft,
  • an overhnng cylindrical casing forming a bearing for both said last mentioned shaft and said spindle, the free end of said cylindrical casing being adapted to coaXially engage the overhanging end of the first mentioned shaft, and a stop on said first mentioned shaft adapted to cooperate with the ends of said cylindrical casing.
