CYLINDER RIDGE REMOVER Filed May 28, 1964 2 Sheets-Sheet 2 INVENTOR JAMES M MOO/e5 BY owywb w a United States Patent 3,264,904 QYLIINDER HEDGE REMQVER James M. Moore, 1929 Prospect St., National City, Calif. Filed May 28, 1964, Ser. No. 370,996 2 Claims. (Cl. 77-2) The present invention relates to a cylinder ridge reamer.
The reamer of the present invention comprises a revolving cutting tool. A removable support for the tool is fixed within the cylinder and this support forms a turntable for the cutting tool. -The support includes an extension which extends above the cutting tool, and this extension is provided with a shoulder. An assembly, including a gear housing and speed reducing gearing, is removably attached to the extension. The gear housing is provided with a shoulder which is adapted to be engaged by the shoulder on the extension to prevent rotation of the assembly when the speed reducing gearing is brought into action to revolve the cutting tool.
A shaft drives the cutting tool and a spline is provided between the speed reducing gearing and the shaft. The speed reducing gearing includes a sleeve which forms a part of the assembly, and this sleeve is connected with the aforementioned shaft by a spline,
Preferably, the shaft is hollow and the means for fixing the turntable to the cylinder, extends through this hollow shaft and through the gear housing so that it is accessible for manipulation above the gear housing.
The cutting tool is carried by a support and this support is adjustably fixed on the turntable to vary the distance of the cutting edge of the tool relative to the axis about which it revolves. Also the cutting tool is yieldingly urged outwardly of the axis about which it revolves.
The surface on the turntable for urging the cutting tool outwardly, and the surface of the cutting tool, which is engaged !by the aforementioned surface on the turntable, are each linear and the surfaces are capable of being parallel of one another while they are in engagement.
Other features and the advantages of the present invention will be apparent from the following description, refference being had to the accompanying drawings wherein a preferred embodiment of the invention is illustrated.
In the drawings:
FIG. 1 is an exploded perspective with sections removed;
FIG. 2 is a view taken along the lines 2-2 of FIG. 1;
FIG. 3 is a side view of the improved reamer and indicating the cylinder wall in phantom;
FIG. 4 is a side view of the cutting tool and a fragment of the cylinder, showing the cylinder in cross section, and showing the portion of the cutting tool at the start of the reaming operation; and
FIG. 5 is a view similar to FIG. 4, but showing the position of the cutting tool when the reaming operation is completed.
Referring more in detail to the drawing, a cylinder 26 is shown as worn, leaving a ridge 22. This ridge is to be removed by the improved ridge reamer, shown generally at 24. The reamer includes a block 26 which is preferably cylindrically shaped. It is provided with three radially extending holes 28 for receiving rods 30. Each of the rods has a shoe 32 affixed to the outer end thereof. The block is provided with a circumferential groove 34 for receiving a garter type coil spring 36. This spring passes through transverse holes 38 in each of the rods 39. The spring normally urges the rods and shoes radially in wardly. A cone 40 engages the inner ends of the rods 30, which cone, when moved downwardly, forces the rods and shoes radially outwardly. The rod is carried by a stem 42 having a screw thread 44. The block 26 includes an upwardly extending and integrally formed hollow "ice sleeve 46 which receives the stem 42 and is threaded to complement the threads on the stem. The upper end of the stem is provided with a tool hold 48 for turning the stem for lowering and raising the cone 40 to thus force the rods 36 outwardly to clamp the block into position in the cylinder and to permit the springs to retract the rods, respectively.
The top 50 of the block 26 forms a support for a turntable 52. The turntable includes a sleeve 54 which extends below the bottom of the turntable and forms a bearing which rides upon the top of the block. An upwardly extending sleeve 56 is formed integrally with the turntable and receives the sleeve 46 of the block 26. The sleeve 46 forms a cylindrical bearing for the sleeve 56 and the turntable 52. A circumferential groove 58 is formed in the upper portion of the sleeve 56 for receiving a split ring 60, which ring limits the upward movement of the sleeve 56.
A substantially U-shaped cutting tool support 62 is carried by the top side of the turntable 52. The turntable is provided with two parallel slots 64 for receiving bolts 66. Counter sinks 6S surround the slots for receiving the heads of the bolts. The bolts extend through the tool supports and are held in place by nuts 70. The top of turntable 52 is provided with a raised section 72, and the legs of the U-shaped support are guided by the side edges of the raised portion. By loosening nuts 70, the tool support 62 can be shifted transversely of the axis of the turntable. Then by tightening nuts 74?, the support 62 can be held in adjusted position.
The tool support 62 is provided with a horizontally extending slot 74 for receiving a lever 76. This slot extends to the periphery of the tool support. This lever is pivoted on a vertically extending pin 78. It is urged outwardly by a coil spring 80. This coil spring is interposed between a ball 82 and a screw 84. The ball engages the lever. Vertically aligned slots 86 and 88 intersect slots 74 for receiving a vertically extending cutting tool 90. This cutting tool is carried by a transversely, i.e., horizontally extending pin 92 having portions extending on opposite sides of the cutting tool. The pin is held in place by the slot 74 in the cutting tool when the tool is in cutting position with the ridge on the cylinder, but can be removed when the reamer is removed from the cylinder.
The upper section 94 of the cutting tool is in the form of a cutting edge, and the lower 96 section is in the form of a guide only, i.e., it is not a cutting edge. The back edge of the tool is tapered to form a vertically extending apex 98. The front of the lever, when it engages the apex 98, is also vertical, whereby, the thrust of the lever on the cutting tool is horizontal, and, since the guide section 96 of the tool is parallel with the axis of the turntable after the ridge is removed, as shown in FIG. 9, the cutting edge 94 cannot move outwardly beyond a line which is parallel with the axis of the turntable.
An eccentric 100 is disposed in the slot 74 for camming the lever 76 inwardly, whereby, when the ridge of one cylinder is removed, the cutting tool is free to move inwardly for the ready removal of the reamer. Also, the eccentric cams the lever inwardly for enough so that the cutting tool clears the ridge of a companion cylinder, whose ridge is to be removed. After the reamer is clamped in the companion cylinder, the eccentric is turned so that the spring can force the cutting tool outwardly. The eccentric is provided with a head 102 disposed above the cutting tool support 62, and is provided with a socket for receiving a Meyers wrench by which the eccentric is rendered operative and inoperative.
The upper portion of the sleeve 56 is provided with a vertically extending spline slot for receiving a spline key 106. The spline key is driven by a hub or sleeve 108. This sleeve 108 is fastened to a worm gear 110 which is driven by a Worm 112. The worm gear and worm are encased in a gear housing 114. This housing is provided with a bottom wall 116 which carries a thrust bearing 118 for worm gear 110; the housing also includes a removable top wall 120 from which a thrust bearing 122 is suspended. Worm 112 is rotated by any suitable means, such as an electric motor (not shown). The worm and worm gear provide speed reducing means.
The top wall 120 is provided with shoulders 124, which shoulders cooperate with shoulders 126 on sleeve 46 to prevent rotation of the housing, i.e., the shoulders 126 on sleeve 46 define a square which extends into a square shaped opening, defined by shoulders 124, in the top wall of the gear housing. In this manner the reaction of the rotating gearing is not transmitted to the gear housing, and the housing is held stationary by the sleeve 46 during rotation of the turntable 52 and the integral sleeve 56.
Thus it is apparent from the foregoing, that by virtue of the present invention, there has been provided a highly versatile ridge reamer, especially designed for continuous power application such as that of a constantly operated electric motor, resulting in constant balanced torque through continuous 360 degree cycles of the cutting tool. In this manner side thrust, such as that which is inherent in manual turning of the cutter tool, is completely eliminated.
The assembly of the gear housing and speed reducing gearing therein is readily attached and detached from the reamer per se. The assembly rests on the pilot post or sleve 46 of the body. It can be removed readily by merely lifting the same off the pilot post. Too, the cooperating shoulders on the pilot post and gear housing, prevent torque reaction of the rotating gearing from being imparted to the gear housing,
By providing for the capability of parallelism of the engaging surfaces of the cutting tool and the lever which urges the cutting tool outwardly, i.e., by providing a linear engaging surface on the cutting tool and a linear engaging surface on the lever, and by providing a guiding edge on the outer end of the cutting tool, aligned with the cutting edge of the tool, and by applying force to the engaging surfaces of the lever and cutting tool at right angles to the axis of the turntable which revolves the cutting tool, the cutting of the tool is defined or limited to parallelism with the wall of the cylinder being engaged by the guiding surface or edge of the cutting tool.
The eccentric renders the lever ineffective for moving the floating cutting tool radially outwardly, whereby, once the cutter support is adjusted for a set of companion cylinders, as for example, cylinders of a multi-cylinder engine, it is necessary only to merely operate the eccentric so that the cutting tool can float inwardly to such extent that it clears the ridge on the cylinder whose ridge is to be removed. Then after the reamer is clamped in position, the eccentric is turned so that it is no longer effective for limiting the outward movement of the lever; then the spring urges the cutting tool radially outwardly.
Any suitable means may be employed for rotating 4 worm 112; such means is here shown as a universal coupling 128.
While the form of embodiment herein shown and described, constitutes preferred form, it is to be understood that other forms may be adopted falling within the scope of the claims that follow.
