VALVE REGULATING MEANS.

APPLlCATlON FILED MAY 28, 1919.

UNITED STATES PATENT 0111 1011.

AUGUST O. DOBRIOK, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE IMPERIAL BRASS- MANUFAGTURING; COMPANY, OF- CHICAGO, ILLINOIS, A CORPORATION OF ILLI- NOIS.

To all whom it may concern:

Be it known that I, AUGUST 0. Dofinrcn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certaln new and useful Improvements in Valve-Itegulatmg Means, of which the following is a" full,

clear, and exact specification.

Figure 1 is a side elevation of my invention shown as applied to the dashboard of an automobile;

Fig. 2 is a central longitudinal section of,

the same on a larger scale;'and

Figs. 3 and 4 are, transverse sections on the lines 33 and 14, respectively, of Fig. 2.

In carrying out my invention, I preferably employ an externally threaded gulde cylinder 10, in which is mounted to slide an adjusting rod 11, which will preferably be. provided with a finger piece 12 secured thereto.

Thecylinder is passed through a suitable;

aperture in the dashboard 13 of an automobile, and is secured in place by the cap 14 screwed onto one end ofthe cylinder and resting against the front of the dashboard 13, while the set nut 15 and lock nut 15 on the other side of the dashboard are screwed up, as shown in Fig. 1, to secure theparts securely in place. The adjusting rod 11 has secured to theinner end thereof the wire 16, which extends to and is secured to the throttle valve of the .carbureter in the customary manner, it being guided and pros tected by the tube 17 preferably formed of spirally wound wire. This tube is secured.

in place by the nut 18 through which it passes and which is threaded on the other end of the cylinder 10 from the outer end on which the cap 14 is screwed.- The end of a wire 16 is conveniently looped through Specification of Letters Patent.

Patented May 11, 1920.

Application (filed May as, 1919-. Serial No. 300,372.

the aperture 19 formed in the reduced end of the adjusting rod 11.

To secure yieldingly the adjusting rod 11 v in any desired position in the cylinder 10, I

form on the rod a' number of shallow annular grooves 20 corresponding to the number of positions to which it ,is desired to adjust the valve, and cooperating with said grooves is a small helically coiled spring 21, consisting of two or more spires, and suitably confined in an annular recess 22 formed in the cap 14 at the end thereof so that the spring 21 is confined between the end of the cylinder 10 and the bottom of the groove 22 in such a manner that the spring can not move except to expand sufliciently to allow the rod 11 to pass from, one position of adjustment tothe other, the springcontracting after it passes each ridge between the adjacent grooves 20 so as to yieldingly hold the rod in any position of-adjustment in a manner that will be readily apparent.

Another feature of myinvention is the novel combination by which the flexible tube 17 is secured to the cylinder 10, and to this end I taper off its end 23,. and insaid tapered end I out two or more slides 24, and form in the outer end of the nut 18a correspondingly tapered portion 25. As the external diameter of the tube 11 is substantially .equal'to the internal diameter of the cylinder 10, it will be obvious that .when' the parts are assembled, asseen at the lefthand end of Fig. 2, and the nut 18 is tightened up, the reduced end of the cylinder 10 will be contracted and will grip the tube 17 very tightly, and hold it as'firmly as if it were soldered, while leaving it in conditionso that it can be readily disconnectedif the wire 16 is broken or it is dewhich I at present consider best adapted to carry out its purposes, it is capable of some modification, and I donot desire to be limited in the interpretation of the. following claims, except as maybe necessitated by the state of the prior art. 1 1

What I claim as new and desire to secure by Letters Patent of the United States is:

1. In an apparatus of the class described, the combination with a guide cylinder adapted to be secured' in the dashboard of an automobile, of an adjusting rod sliding therein and provided with annular grooves thereon, a short coiled spring surrounding said rod and adapted to cooperate sin 1y 5 with any of saidgrooves, and means or confining: the spring to prevent its movement with the rod while permitting expansion to allow the rod to be adjusted to and heldin any of its positions of adjustnient 2. In an apparatus, of the class described, the combination with a guide cylinder adapted to be secured in the dashboard of an automobile, of an adjusting rod sliding therein and provided with'annular grooves thereon, a short coiled spring surrounding said rod and adapted to cooperate singly with, any of said grooves, and a cap screwed on one end of thecylinder and having an annular recess therein adjacent said end of the roper dimensions to receive and confine the s ring in the manner and for the purpose set orth, p

. In an apparatus of the class described, the combination with an externally threaded guide cylinder, of an adjusting i-od sliding therein and provided with annular'grooves thereon, a short coiled spring'surrounding said rod and adapted to cooperate singly an automobile and having its rear end externally threaded and provided with a taadapted to be secured in the dashboard of pered, split portion, of an adjusting rod I sliding therein, means for holding the rod in any desired position of adjustment, a wire attached to the endof the rod, "a flexible tube adapted to fit in the end of the cylinder, and a nut threaded on the rear end of the cylinder and having a reduced internally tapered portion cooperat ing with thetapered and split endv of the cylinder for the purpose described.

In' witness whereof I have hereunto set my hand and affixed my seal this 20th day of May, A. D. 1919.
