A. w. NOYES VALVE RESEATER Filed Feb. 12, 1920 Patented May 15, 1923.
PATENT @FFEQE.
ARTHUR w. NOYES, or ARLINGTON, VERMONT.
V ALVE BESEATER.
Application filed February To all whom it may concern Be it known that ARTHUR lV. Norris, a citizen of the United States of America, rcsiding at Arlington, in the county of liennington and State of Vermont, has invented new and useful Improvements in Valve Reseaters, of which the following is a specification. I
The object of the invention is to provide a valve grinding or reseating tool adapted especially for use in connection with engines of the explosion type for reforming the seats whether of the fiat or conical. variety without dismantling the engine other than to remove the valve bonnet and valve, to the end that the repair in this respect of an engine may be accomplished without resort to the machine shop, and hence without the loss of time ordinarily incident to the indicated operation, and with this ob ject in view the invention consists in a tool of which a preferred embodiment is shown in the accompanying drawing, wherein:
Figure l is a view partly in side elevation and partly in section showing the invention in operative relation with a valve seat and casing, the casing being indicated in dotted lines.
Figure 2 is a detail of the inner end of the spindle.
Figure 3 is a section on the plane indicated by the line 3-3 of Figure 1.
Figures 4, 5 and 6 are sectional views respectively on the planes indicated by the lines 4.-4c, and 66 of Figure 1.
The device consists essentially oi a threaded shank 10 provided at one end with a wrench or brace seat 11 suitable for the attachment of means whereby the shank may be rotated, and a reversible bit 12 fitted upon a seat 13 at the opposite end of the shank and held. in place by a suitable nut 14, said nut preferably being of circular contour to form a device to hold the bit in proper relation to a port while turninn the tool to cause the proper cutting of the surface of the cylinder wall around said port and constituting the valve seat. The seat 13 constitutes a cross sectionally square or angular guide or centering 12, 1920. Serial N0. 358,285.
portion of a reduced extension of the shank, the extremity of this reduced extension beinn threaded to receive the nut.
The bit is of conical form in contour with a fiat cutting surface 15 for operation upon, flat valve seats, and a conical cutting surface 16 for cutting conical valve seats, it being obvious that the bit may be reversed in position from that indicated in Figure l to adapt it to the position of the seat which is being; treated.
In threaded engagement with the shank of the tool is a gauge nut 17, preferably counterbored as at 18. This nut serves as a gauge el ment being adapted for abutting con act with the top of the valve casing through which the shank of the tool is inserted and serves, when in such contact, to prevent further cutting of the tool on the valve seat. By this means excessive cutting of the valve seat is precluded, but any desired depth of cutting may be obtained by the proper adjustment of the nut on the shank.
In plan the bit is preferably cruciform to the end tl at it may with facility be inserted through a port opening to provide for cutting a valve seat located at the inner surface of the wall in which the port is formed.
That is claimed is:
A tool for the purpose described having a shank provided with a wrench seat at one end and threaded substantially throughout its length, the shank at the extremity re mote from the wrench seat being reduced and made cross sectionally angular to provide a seat. the terminal of the extension being exteriorly threaded, a reversible bit fitted on said seat and provided with flaw and conical cutting surfaces, a circular guide mounted on the threads of the reduced extension and bearing against the bit to maintain the same in place, and a gauge nut mounted upon the threads of the shank for contact with a valve casing.
In testimony whereof he afiixes his signature,
ARTHUR W. NOYES.
