UNITED STATES" DENNIS T. IGOU, OF
SPRINGFIELD, OHIO.
VALVE-GRINDING roon.
Application filed December 22, 1924. Serial No. 757,354.
This invention relates to a valve grinding device, it particularly relating to a valve grinder'cf the'vacuum cup type. I
An object of my invention is. to provide a device of this character employing a vacuum cup which is adapted to different sized valves.
A further object of the invention is to'so construct the vacuum cup as to lend the maximum flexibility to the tool.
In the accompanying drawings:
Fig. 1 is a vertical section of a tool embodying the improvements.
Fig. 2 is a view of thesame shown applied to the valve, the valve seatand a portion-of the tube being shown in section.
Fig. 3 is a view similar to Fig. 2 but showing the vacuum cup applied to a smaller sized valve. V
Fig. 4 isa view of the-lower end of the vacuum cup. 7 r
Fig. 5 is an enlarged section of a portion of the vacuum cup showing an additional feature. 7 a
In the drawings, 1 represents a vacuum cup constructed in the usual way of flexible rubber and having an integrally formed stem 2. The edge of the cupis provided with an annular inclined or bevelled face g to form a seat for the valve and the interlor of 'the cup is also provided with a second inclined or bevelled annular face 4 to form another seat for the valve. The second seat 4 begins where seat 3 ends and is formed at a greater inclinati0n.; Y I V The stem of the cup istormed with a bore or recess 5 toreceive the shank 6 of a wooden handle 7, the bore being preferably cast with an annular-bead 8 which is received in an annular groove 9 in the handle so as to more firmly secure the handle in position. This bore 5 terminates at a point substantially midway the length of the stem and extending from this bore 5 is asmaller bore 10 terininating in an enlarged chamber 11.
The operation is as follows: Referring to Fig. 2 there is shown a valve 12 of the larger size and in this case the valve is contacted by the seat 3, the cup being first firmly pressed upon the valve to exclude the air from the interior of the cup so that the cup will be held to the valve by atmospheric pressure in a well known way. By grasping the handle 7, but a portion of ,whichis shown 7 in the drawings, it will'be understood that g the valve may be rotated upon its seat. By reason of the cored-out bore 10 and chamber 11 a greater flexibility is imparted to the stem of the valve so thatthe tool may be applied to valves which are inaccessible to some valve grinding tools such as the rear valveio'f a Ford engine. If necessary the stem of the valve and the handle can be bent to the position shown in dotted lines in Fig. 2 and the valve rotated with the parts in that position.
In Fig. 3 the tool is shown appliedto smaller valve 14 in which case the seat 4: is caused toengage the valve With equally good results. I
In Fig. 4 each of the seats 3 and 4 is shown provided with annular ribs which act to compensate for any irregularities on the valve caused'by pitting or carbon. The ribs. sinking into the low places on the to makea tight air'joint,
Having thus described my invention, I claim; I
1. In a valve grindingtool, a vacuum cup having an outer flat inclined annular seat and an. inner fiat inclined annular seat, the inner seat being formed at a greater inclination than the'outer seat, said inner'seat be- .ing adapted to engage a valve of the smaller size and said outer seat being adapted to en gage a valve of the larger size.
In a valve grinding tool, a rubber vacuum cup having an integral flexible stem, said stem being provided with a bore at its outer end to receive the shank of a handle and also provided with an inner chamber valve, act
having a communication with said outer jecting a slight distance from the face thereof, for the purpose specified.
In testimony whereof I have hereunto my hand this 18th set day of December 1924. DENNIS T. 'IGOU.
