JACOB` B. ROSE, OF CLEVELAND, OHIO, ASSIGNOR TO THE MARVEL ACCESSORES Ill/[ANU- i FACTURING- COMPANY, OF CLEVELAND, OHIO, A CORPORATION. i
To all whom it may concern:
Be it'knownthatl, JACOB B. ROSE, citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new and useful Improvements in Valve-Grinding Tools, of which the following is a specification.
Thisinvention consists in a valve grinding tool adapted tobe operated by hand, all substantially as' shown ,and described and particularly pointed outinthe claims.
In the accompanying drawings, Figure 1 is a; plan view of theftool with the crank handle for operating the same in position as in Fig. 3. Fig. 2 is a sectional horizontal plan on line 2 2, Fig. 3. Fig. 3 isa side'` elevation of the tool and a valve engaged thereby. Fig. 1 is a detail of the ball socket secured in the top of the casing. Fig. 5 is a longitudinal sectional elevation of the complete tool on line 5*-5, Fig. 1. Fig. 6 is a detail of, the Vthimble which `serves vafs a bearing for the actuating shaft.
The idea of the invention is to provide a convenient and effective valve grinder for automobilists, particularly, and of a size which can be carried conveniently on the car with other needed tools, so that if a leaky valve or valve seat be found it can at once be put in good working order and without calling in an expert to do the work. To these ends the tool or device comprises a main shaft s which may have a total length of nine inches, more or less, and a casing or head c of such size as to be comfortably grasped by the hand and in which said shaft is mounted to rotate or rather oscillate within suitable working limits, such oscillation being designed to give the valve a corresponding movement.
The said shaft carries a valve engaging wrench plate 2 or equivalent means in a slot in its lower extremity and which is secured in said slot by a cotter pin 3, or its equivalent, for convenient removal or reversal, the said plate having teeth et at its opposite edges differently spaced apart to engage valves of different sizes.
The said head or casing is built in two stamped sheet-metal sections or halves 5 and 6, respectively, which are constructed with corresponding diagonal or inclinedA inner edges adapted to match and one of which has spurs 7 at its inclined edge and the other holes 8 in which said spurs are engaged and Specification of Letters Patent.

tends across the axis of said shaft to the opposite side, while the upper bearing and thrust support for the shaft is inthe topr The -said bearings are `re-l of section versely flanged or sleeved, and al vsocket 9 is seated from theinside in the upper bearing and carries a ball 10 in its top to take the direct thrust of the shaft. rlhe said socket is flared or flanged inside against the wall of the head about the sleeve therefor and also has a plurality of spurs 12 engaged thro-ugh said wall to fix it in place, and a Cotter pin 13, or its equivalent, through shaft s over its lower bearing in the casing c confines the shaft in workingrpositio-n.
Operation or oscillation of shaft s is effected by means of a yoke 14 engaged therewith at its divided end by cotter pin l5, or its equivalent, and said yoke is `pivotally en? gaged at its closed end by a short arm 16 views 2 and-5 and may be said to be equal to about 115 degrees or a quarter of a complete circle. l v
The said shaft 17 is supported in a thim-V ble 18 set into a flanged opening in the side of casing c at a point directly opposite the pivot pin 15 of yoke 14 in said shaft s, and is fixed in place by spurs 19 through the wall of the head similar to the socket 9. This provides also for removal of said thimble and socket when necessary but otherwise fixes them firmly in place. v
The casing being struck up from sheet metal it is possible to form unitary bearings therein for the respective shafts, and especially since the casing is divided on diagonal lines and which makes the part 5 one member with a bearing struck in its top, and the ioo part or section 6 another member with bearings in its bottoni and side respectively. The diagonal division of the casing is also advantageous in assembling, since all the operating connections are inside, because it en-y ables both shafts to be inserted in section 6 and the Working connections between the same to be made and held together before the section 5 with its end thrust ball bearing in cup or socket 9 is put in place. A like convenience occurs when for any reason the parts are Vto be separated, as for repairs or replacement.
lWhat l claim is:
l. A valve grinding tool having a casing and a drive-shaft and a driven shaft mounted at right angles to each other therein, a yoke engaged with said driven shaft and a bent arin fixed on said drive shaft and pivotally connected with said yoke.
2. A valve grinding' tool having` a drive shaft and a driven shaft and a casing supporting said shafts, inv combination with yoke pivoted on said driven shaft and a curv-ed arm fixed on the end of said drive shaft and pivotally connected with the otherwise free end of said yoke.
3. A valve grinding tool havinga shaft provided with an open slot in its lower end and a reversible valve Wrench in said slot constructed at opposite edges with teeth variably spaced apart to engage valves of different sizes, and means to support and actuate said shaft.
4. A. valve grinding tool having a casing adapted to be gripped in a hand and consisting of tivo struck-up sheet metal sections divided diagonally across the axis thereof from top to bottom, the outer of said sections provided with a shaft bearing in the top thereof and a cap in said bearing, and the inner section having bearings in its bottoni and side respectively, the latter bearing having a thimble therein, a drive shaft through said thinible bearing and a driven shaft in said other bearings, and said shafts operatively connected.
5. A valve grinding tool comprising a casing of a size adapted to be grippedin one hand and constructed invtvvo sections united on a. line diagonal to the middle thereof from top to bottoni and said sections having opp-:i-l site bearings in their top and bottoni respec tively, a driven shaft centrally through said casing supported in said bearings, said top bearing being adapted to take the end thrust of the shaft, and a drive shaft through the side o-f the casing operatively connected with the said driven shaftand adapted to oscillate the same.
Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this 16 day of November, 1916.
