GAs-ENGINE-VALVE GRINDER.
citizen o i the United States, residing at Berwick, inthe county of Columbia., State of Pennsylvania, have invented cei'tain new and useful Improvements in Gas-Engine-Valve Grinders; and I- do hereby declare the following to be a full, clear, and exact description of the invention, rsuch as will enable others skilled iiikthe art to which it apper tainsfto make and use the same.
'1`hisinveiition relates to tools and ,more
particularly to tools designed `for use in grindingtlic valves and seats of gas engines of the usual puppet valve type and has for its object to providel a device of this kind by means of which the valves and seats may be sin'iultaneously ground without removing the valves and stems or the valve springs.
Another object is to provide a device of be easily and quickly applied.
In the drawings:
Figure 1 is a section taken through the exhaust outlet and adjacent parts oi' a gasolene motor, illustrating the use 0i the present invention.
valve seat indicated at Ain Fig. 1.
Fig. 2 is a view showing only a fragment of the engine invsection, and illustrating the act of placing the grinder in position.
Fig. 3 is an elevational view of the grinder.
Figli is a top plan of the grinder.
Fig. 5is a section on line 5 5 of Fig. 4 showingthe arrangement of the beveled faces at the opening of the grinder, in perspective.
Referring now to the drawings the present invention comprises an annular member 6 having its periphery and underface beveled as indicated at 7 to conform to the bevel ot' a The upper surface of the annular member (Sis beveled downwardly and inwardly as indicated at 8 to conform to the bevel of a valve indicated at B in Fig. 1. It will be understood that these beveled surfaces 7 and 8 conform absolutely to each other so that when a valve is ground upon the surface 8 it will fit a seat ground by the surface'?. l
At one point the annular member, 6 is'cutv away as indicated at 9 to form a passage communicating With the inclosure of the aniiulus and opening through theouter surface of the member. This forms what Will be termed an open annulusand by the term Specification of Letters Patent.y

faceslie at the ends of the surface S so that there can be no cutting action during the operation of the grinder which would result if the ends of the surface 8 at the sides of the opening 9 were left sharp. y
At a point dimetrically opposite the opening).v the member 6 is provided with an ontwai'dly extending radial ear 12. An operating handle 1'3 is provided which consists of a short normally vertical stock 14 having a suitable grip 15 at its upper end. At the lower end 'of the stock 14 there is a laterally and downwardly inclined extensio"A 16 `having its lower end turned verticaliy and bi-4 i'ui'cated as shown at 17 to embrace the ear 12 to which it is pivoted by means of a pin 18.
livoted to the handle 13 at the union of the stock 11 and the extension 16 there is an arm 19 which extends normally down- 'ardly 'and laterally in true divergent relation to the extension 1G, and this arm carries a lip 20 at its lower end arranged to engage within the opening 9 betweenthe straight lower portions 21 of the faces which lie at the sides of this opening. A slight shoulder Q2 is formed upon each of these :faces 21 so as to be engaged by the under face of the lip 20.
In use, the valve stein and valve of a motor are raised in any suitable way against the action of the valve spring indicated at C in Figi 1. The member G is then engaged between the valve and thevalve Seat, With the face 7 directed downwardly, 'rt being understood that the opening 9 is of a width to permit the passage ot' the valve stem therethrough. During this operation, of course, the parts are in a position shown in Fig. 2. The operating handle is then moved upon the pivot pin 18 and the lip 20 is engaged in theopening 9. Oscillation of the grip 15 will then result in grinding of the valve and seat, it being understood that suitable grinding compound has been placed upon them.
During the operation of valve grinding it is of course important that the grinding surface be separated occasionally to prevent scarring. To accomplish this there may be employed a valve lifter of the chain and lever type such as is illustrated in Fig. 1 and indicated atD. lith such a lifter the 'operator may occasionally lift the valve against the' action of the spring C by foot pressure as illustrated. In engines emplo ing powerful valve springs the lever mayY engaged beneath the collar indicated at as Aillustrated in dotted lines in Fig. 1 so that the1 pressure of the spring may be reduced should this pressure-'be .such as to interfere with the operation of the grinding tool.
'hat is claimed is:
1. A valve grinding tool comprising a body portion provided with a passage therethrough and hav-ing a valve receiving face at one side surrounding the passage and a valve seat engaging face at the opposite side ing a valve seat engaging surface at the opposite side surrounding the passage.
3. A vvalve grinding tool comprising a member having .t passage formed therethrough and having a split communicating with the passage and opening through the outer face of the member, said member having a valve receiving surface formed at one side and surrounding the passage and having a valve seat engaging surface at the opposite side surrounding the passage and a handle pivoted to the member at one side and including an arm arranged for engagement in the opening.
4. A valve grinding tool comprising a' grinding member provided with a stem receiving passage therethrough, and having a split communicating with the stem receiving passage and opening through the outer face of the member, and a handle plvoted to the member and including an arm arranged for engagement in the split.
In testimony whereof, I affix my signature, in the presence of two witnesses.
