ADJUSTABLE CAM-SHAFT THRUST BLOCK.

Application filed July 9,

To all tU/LOIIL it may concern:

Be it known that I, PERRY B. Enwanns,

a citizen of the United States, residing at Athens, in the county of Greene and State of New York, have invented new and useful Improvements in Adjustable Cam-Shaft Thrust Blocks, of which the following is a specification.

The object of my said invention is the 19 provision-of a cam-shaft thrust-block possessed of the capacity of adjustment and therefore adapted to take up end play and avert knocking of the engine of a well known type of automobile.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a view illustrative of the application of my novel thrust block.

Figure 2 is an elevation of the thrust block per se.

Figure 3 is an elevation of the thrust block taken at right angles to Figure 2.

Figure 1 is a vertical central section of the block taken in the plane indicated by the line H of Figure 2. I

Figure 5 is a cross-section of the block taken in the plane indicated by the line 5--5 of Figure 3, looking in the direction indicated by arrow.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

My novel thrust block per se is made up of a body 1 of steel or other appropriate material, a headed and threaded bolt 2 and a nut 3. The thrust block is shown in Figure 1 connected to a support 13 which may be any appropriate part of an automobile. The body 1 is provided with an end flange 1. and a longitudinal central bore It is also. provided with reduced end extensions 6, separated by a V -shaped space 7, and is further provided with shoulders S at the inner end and outer sides of the extensions 6, and slots 9 arranged adjacent to but spaced from the said shoulders 8. The head 2 of the bolt 2 is tapered in conformity to the inner sides of the extensions 6, as illustrated.

As clearly shown n F gure 1, my novel 1923. Serial No. 650,559.

thrust block is applied to the middle bearing 10 on the cam-shaft 11 of the engine embraced in a well known type of auto- 1 Notwithstanding the practical advantages ascribed to my novel thrust bar the same is simple and inexpensive 1n construction and is Well adapted to withstand the usage to which thrust blocks are ordinarily sub-.

jected.

I have entered into a detailed description of the construction and relative arrangement ofthe parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I

do not desire, however, to be understoodas confining myself to the specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my inventionas defined in my appended claims.

Having described my invention, what I claim and desire to secure by LettersPatent, 1s:

1. A thrust block comprising a body having a longitudinal central bore and an end portion and a tapered bifurcation therein and also having slots adjacent tosaid end portion, in combination with a headed and threaded bolt, and a nut mounted on said bolt and opposed to one end of the body.

2. A thrust block comprising a body having a longitudinal central bore and an end portion and a tapered bifurcation therein and also having slots adjacent to said end portion, in combination with a headed and threaded bolt, and a nut mounted on said.

bolt and opposed to one end of the body; the said bifurcation of the body forming end extensions on the body, and the said end extensions being reduced.

3. A thrust block'coinprising a body lmvthe head of the bolt being tapered in (FOU- ing a longitudinal central bore and an end formity with the tapered bifurcation in the portion and a tapered bifurcation therein body. 1 and also having slots adjacent-to said end In testimony whereof I afiix my signa- 5 portion, in combination with a headed and ture.

threaded bolt, and a nut mounted on said bolt and opposed to one end of the body; PERRY B. EDXVARDS.
