Specification of Letters Patent.
rammed-new., ee, 'iota Application filed June 27, 1916. 'Serial No. 106,215.
To all whom 'it may concern.' l
,Be it known that' I, VALENTINE Pirsmn, a citizen of the United States, residing' at ew York, in the county'of Bronx and State of N ew York, have invented new and useful Improvements in Valve-Grinders, of which the following isa-specification.
The invention relates to an improvement in valve grinders, particularly designed for use in grinding automobile valves in then seats.v v i ln grinding* this type of valve, it has been found that to secure a proper seat it is-necessaiiy to reciprocate the valve on its lseat following the application of a suitable valve Agrinding' compound, the valve being reciprocated` rather than rotated in order to secure contact under any and all conditions, as the valve. frictronally rotates in use. I
The improved valve grinder comprises a stemformed at one end with a handle and at the opposite end with an appropriately shapedl terminal to engage the valve, the stem having,r a longitudinal movable element and there being1 provided a cooperating connection between the stem and element to rapidly and rotarily reciprocate the stem the valve inthe movement of the element longitudinally of the stem.
The invention in the preferred form of details will.be described in the following; specification, reference being; had particularly to the which: A
Figure 1 is a view in elevation, partly in section, illustrating the improved valve grinder. Fig. 2 is a, transverse section on the line 2 2 of Fig. 1.
The improved valve grinder comprises a stem l of appropriate lengthformed at one end as 2, with a screw driver terminal or other appropriate terminal by which the rod may be temporarily connected with the valve disk. The opposite endof the stem is provided with anappropriately formed handle 3, the juncture of the stem and han* dle being such as to permit independent rotation of the parts, in order that` the handle may be utilized to apply sufiicient grinding` operation accompanying drawings, in
without interfering with the rotary more ment of the stem.
The stem 1 opposite sinuous being diametrically opposite and parallel throughout their lengths. Preferably" the lateral deviation' of the maximum limit of any one 'phase of the groove is approximately twolthirds the stem, so that the stem proximately 'throughout circumference. made up of a series of phases, one merggdn'gginto another, and the operating' element 5 in the form of a sleeve, which is freely slidabde on the stem circumference of the is reciproczntedY two-thirds ofthe" The respective grooves aref 1, is provided with! is longitudinally ferma wat y grooves 4, these grooves,
threaded pins 6, which terminally" seat in the respective grooves. It is apparentthat reciprocation of the sleeve causeegfza-seri s of rotarily reciprocating` movements of the.;y
stem, .and thereby of the valve in-whichfthe. reeiprocatf stem 1s connected, these rotarily ing movements being successively in oppo site directions and to a number correspond ing to the number of distinct phases of the grooves in thelength of the stem. herefore in a singl sleeve longitudinally of the stem, the latter will be oppositely number of times, thereby rapidly grindingthe valve.
`Havingf described my invention what claim and desire to secureby Letter-'sPat-lv ent is:
A valve grinder includinga a stem, a haar die mounted on one end thereof, the opinos site end of the stem being integrally' formed `to engage the valve, said stem being' formed with opposite sinuous grooves, and a sleeve slidably embracing the stem and formed at diametrically opposite points with countersunk threaded openings, and pins threaded in said openings and having terminals to freely engage the sinuous grooves, the sleeve loosely iitting` the stem and the plain terminals of the pins loosely fitting the grooves, whereby to ing' in operation.
1n testimony whereof l affix my signature.
