v'nnvn To all whom a may amm- Be it known that I, ,A Horseman,
.a citizen of the United States, and .a res1- dent ofBufialo, in-the count of Erie and- State of New York, have 'ma I e' certam new and useful Improvements in Valve S lencers,
of which theiollowing is a specification;
My presentinvention relatesgenerally to valves of internal combustion moto pets or cross arms whereby either-enclosed usual cam shaft, my object being thepro vision of means adaptable to bothtappets' and'cross arms for the purpose of silencing-j the valves and preventing the-usual noises.
brought about by enga ement of thes ejnor mally spaced apart va ve actuating parts,
In the accompanying drawing which il lustrates my, present invention and a part of this-specification, I Figure 1 is a vertical sectional view showing the practical application of my invention in connection with an enclosed valve,

-28 of an ov erheadflvalve arrangement conno My invention proposes a silencer which as appliedtq valves of the above t pe includes a cylindrical shell 13, externa lythreaded to screw. into, the bore '10 of the tappet 10, having a reduced portion at one endvand' havin at its opposite end 'an. enlarged polygonal ead 14m. facilitate adjustment] thereof in the: tap'p et bore, a lock nut 15' being employed thereon to lockthe shell in K ad usted position within the .tappet' bore.

I have shownthe 'shelli13; as provided with adpin 24fitting 'transverse; '14, and. through slotted. 25 of the stem 19" and bushing 21 openings I I -fwhich hus. holds the stemagainst rotation,

I have also sho'wn the' shell 13 as provided: with in'clined 'oilopenin and whose outer 'endsopen into oil ,groovee. 27in'thefloute'r face-of the head 14. a My inventionasapplied the rocker arm:
I permissible ',movement between the head 20 of the stem 19 and thehead 14 of templates an externally threaded cylindrical shell 13 illustrated in Figures 4, and 6 vwhich is adapted to be screwed through one is spaced from the adjacent end of the shellv f with or without an interposed fiber or other been loosened. 'tion is obviously the same, however, as that washer 22. At its other end the stem has bearing through a reduced 0 enin'g 1'2 of the shell, the end of the shel adjacent to opening 17 being transversely slotted as at 29 so as to form aguide for the reception of a pin 24 which extends through the stem 19 and thus movably holds the stem in connection with the shell 13 and also provides for the reception of a screw driver or likev implements-for adjusting the shell 13 in the rocker'arm 28 after the lock nut l5 has The result of this construcdescribedwith respect to Figures 1, and 3, and it is equally obvious that my invention according to both constructions may be applied with ease and facility in actual operative connection with those parts of valve actuating connections where clearance must ordinarily be left in view of the ex which will eliminate the usual noises, known as valve taps and that it will obviate necessity for the fine; careful adjustments ordinarily required.
