To all 207mm t may concern.' Y Y Be it known that I, MARTIN L. BUSH, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented a new and useful Gearing for Valve-Grinders, of which the following is a specification.
This invent-ion relates to a tool especially designed for grinding valve seats and valves, one of the objects of the invention being to provide a device of this type which can be used not only for the purpose stated but also as a brace for operating bits or drills.
A further object is to provide a structure of this character adapted, when operated, to rotate the engaged valve in opposite directions successively or to rotate the valve engaging stem continuously in one direction only.
With Vthe foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and` claimed, it being understood that changes in' the precise embodiment of the invention herein disclosed, can be made within the'scope of what is claimed, with-V out departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown. In said drawings: Figure l is a vertical Vtransverse sectionpthrough the device. Fig.
2 is a section on line A-B Fig. 1.
Referring to the iigures by characters of reference l designates the body of the tool, the same being preferably a single casting forming a frame in the lower portion of which is provided a central opening Q, for the reception of a tubular guide or holding member 3. A set screw 3 is provided for engaging this holding member to secure it against movement within the body. Extending laterally from the body 1 is a stud 4 on which a wheel 5 is mounted for rotation', Athis wheel being detachably secured on the stud in any suitable manner and being reversible. One side of the wheel is provided with a mutilated gear 6, while the other side has a continuous gear 7. Either of these gears is adapted to mesh with oppositely disposed bevel gears-8 and 9 located at the ends of guide 3 and mounted on a stem 10 which is adapted to rotate within the guide 3. Each of the gears is secured to the stem or spindle 10 by means of a vset screw 11.V A
wheel 5 can be rotated and, consequently,
the mutilated gear will first rotate gear 8 in one direction and then rotate gear 9 in the opposite direction so that stem or spindle 10 will thus be correspondingly rotated back and forth, thereby producing a better grinding action than is possible where ythe valve 1s rotated continuously in one direction. However, should it be desired to rotate the valve continuouslyV in one direction, it would merely be necessary to reverse the wheel 5 so as to bring the gear 7 into mesh with the two gears 8 and-9. By then loosening one of the set screws 1l, so as tovrelease its gear 8 or 9 fromthe stem or .spindle 10, the wheelv 5 can be rotated and motion will be trans-- mitted through gear 7 and oneof the gears 8 or 9 to the spindle 10. This last arrangement .is preferably usedV where the tool is employed for'rotating a bit or drill.
The gears 8 and 9 differ as to the number I of teeth thereon with the result that during the actuation of the tool, for the purpose of grinding a valve, the valve will be moved forwardly a greater distance than it is moved backwardly with the result that it will not be brought back to its original posi-v tion on the seat as has been the case hereto- Y a body, a longitudinally adjustable tubular member therein, a spindle mounted for ro-l ing provided on one side With a mutilated gear and on lts other 51de with a continuous v gear, and means for rotating the Wheel. j

A tool of the class described including a body, a tubular member adjustablelongitudinally therein, a'spindle mounted for rotation in said member, gears detachably secured `tothe spindleV and adjacent the ends ofthe tubular member, a stud extending Copies of this patent may be obtained fer `:"we cents each, by addressing the Commissioner'of Patents,

InV testimony that I claim the foregoing as my own, I have hereto aihxed my signature in the presence oftWo Witnesses.
