TION OF CALIFORNIA.
A CORPORA- VALVE GRINDER.
Application filed August 8, 1919.r Serial No. 316,049.
To all 'whom t -flf'iay camera.'
Be it known that I, EARL H. HOWARD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and usel fui Improvements in Valve Grinders, ot which the following is a specification.
This invention relates to valve grinding machines and particularly to valve grinding machines adapted to be used forvgrinding in poppet valves such as are used in internal combustion engines common m automobile practire. lt is an object of the invention to provide a simple, compact and efl'estive machine of this character.
In order that poppet valves be tight they must be iliade to seat properly.r Valves of this type are generally made to seat tightly and properly by grinding them in with emery. This grinding in is generally done by placing a compound of emery between the valve and the valve seat and then giving the valve an oscillating rotating motionl by means of a .screw-driver or the like. The reason for giving the valve an oscillating, rotating motion-that is, :i motion so that it rotates through a small angle in one direction and then rotates through a Small angle in the other direction, is because continuous rotation of the valve in one direction will cause rings or grooves to form either in the valve seat or in the valve itself. The grinding in oi" valves by hand is slow and laborious and is therefore expensive. By the present invention an electrically driven machine is provided which will properly grind in a valve in a fraction of the time required to do .it by hand. I l
The present invention provides a machine in which an electric motor, through a suitable mechanism, gives an oscillating, rotative motion, such as is required for grinding in a valve` to a shaft. This shaft which is driven bythe motor is adapted to have a member attached to it which will engage a valve so as to cause it to be driven by said shaft.
A particular feature of the invention is the compactness and simplicity of the mechanism. which gives the required motion to the shaft. The compactness of the mechanism makes the machine easy to handle while the simplicity minimizes the danger of parts getting out of order and thereby makes the i machine particularly durable.
Further objects and features of the invention willbe readily understood from the following detailed description of a referred orm of the invention in which re erence is had to the accompanying drawings in which` "Fig, is a side elevation of the machine; 111g. is an enlarged detail section taken as indicated by lines 2-2 on Fig. 1; Fig. 3 is a detail section taken as indicated by line on Fig. ,2; Fig. 4 is a detail section taken as indicated by .line 4 4 on F ig. 3; Fig. 5 `is a detail section taken as indicated by line 5-5 on Fig. 2; and Fig. 6 is a detail section taken as indicated by line 6-6 on Fig 5.
.l'hroughout the drawings numeral 10 designates the casing of the machine in which is carried an electric motor. The casing 10 lis preferably shaped as shown in Fig. 1 so as to form a handle 11 which provides a convenient means for handling the machine. A portion 12 of the casing in which there is a .switch is preferably provided near the handle 11, and a button 13 for operating the switch in portion 12 may be located so that it may be conveniently operated from the handle 11. Lead wires 14 enter the inachiiie throng-jh :i conductor 15 and the current entering the machine through lead wires 14 is controlled by the switch inthe portion 12.
` Suitable veiitilatiiig holes 16 and 17 may be rprovided in the casing 10 to allow a circulation of air around the motor within said casing to prevent it from becoming overheated. The shape, arrangement and proportions of the casing 10 may be varied to suit conditions but it is preferred that they be substantially as shown in the drawings. The shaft 18, of the motor which is within the casing 10, extends'fr'oin the bottom 19 of said casing 10, and has mounted on .it a pinion 20. The pinion 20 engages and drives a gear 21 which is mounted on a pivot pin 22. The pivot pin 22 is mounted in and extends from the bottom 19 of the casing 10. Formed integral with the gear 21 and therefore driven by said gear there is a pinion arranged as shown in Fig. 3. The pinion 23 engages and drives a large gear 24 which is mounted on a pivot pin 25. The pivot
