CLAUDE FRANK NEWMAN,

AND FOUNDRY COMPANY, OF NEW YORK,

OF ST. LOUIS, MISSOURI, ASSIGNOR TO AMERICAN CAR N. Y., A CORPORATION OF NEW JERSEY.

DASH CONTROL.

Application filed May 14, 1923. Serial No. 638,768.

I '0 all whom it may concern:

Be it known that I, CLAUDE F. NEWMAN. residing at St. Louis, Missouri, and being a citizen of the United States, have invented certain new and useful Improvements in a Dash Control, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art. I

In said drawings:

Fig. 1 is a side elevation of the invention shown as applied to the instrument board of an automobile; I V

' Fig. 2 is a central longitudinal section of the same on a larger scale;

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1 looking in the direction of the arrow; I

Fig. 4 is a transverse section taken on the line 33 of Fig. 2 looking in the direction opposite to the direction of the arrow; and

Fig. 5 is an elevation of a modified form of my device, looking towards the right in Fig. 1, the adjusting rod being shown in section.

This invention relates to valve regulating means and more particularly to a means adapted to be applied to the instrument board of an automobile for adjusting the position of the choker valve of the air' intake of the engine carbureter to control the air supply thereof.

As shown in strument board 1 is provided with an opening 2 in which is slidably mounted a rod 3 provided with a series of shallow annular grooves tspaced a short distance apart and extending for the greater part of the length of the rod. At its outer end the rod is provided with an operating handle or kuob 5 and projects through the support 1, being provided at its inner end with an opening 6 to which is secured a wire (not shown) which connects with the choker valve of the oarbureter. Surrounding the rod 8 and enthe drawings, a support or ingaging the face of the instrument board is a guide plate or guide 7 secured thereto by the bolts 8 which also serve to hold the looking spring 9 against the rear face of the instrument board. The locking spring 9 is formed from the strip of spring metal folded to a substantially U-shape and having flanges 10 provided with openings through which the bolts 8 pass to receive the lock.

washers 11 and nuts 12. The body of the locking spring 9 is provided with a flat outer portion 16 in which there is formed an opening 13 through which passes the rod 3, the locking spring 9 thus aiding in guiding the rod 3. The sides 14: of the body are provided with projections 15 formed by indenting the sides 14, these indentations being placed opposite to each other and the projections 15 formed thereby being adapted to engage in opposite sides of the grooves on the rod 3. The sides 14 possess suflicient resiliency to permit of the sides being sprung apart when the projections 15 are engaged by the portions of the rod between the shallow grooves 4: and to cause the projections 15 to snap back lnto the grooves as the grooves come opposite the projections thereby serving to retain the rod 3 in position when the projections 15 are in engagement with a groove and readily permitting of the moving of the rod to another position by the application of pressure on the knob 5. Should the rod 3' or projections 15 wear so that the rod is not securely held,the projections can be reformed so as to engage more annular grooves by squeezing thespring 9 between the cutters of a pair of pliers, the

edges of the cutters engaging the spring 9 in line with the projections 15.

The construction of the modified forin shown in Fig. 5 is identical with the construction shown in Figs. 1 toe except that the rod 3 of Figs. 1 to 1 is replaced by a rod 30 of angular crosssection which passes through a correspondingly shaped opening 130 in the end of the spring 9. In this construction, the shape of the rod 80 and the opening 130'prevents rotation of the rod 30 in its support and twisting of the wire which connects the rod 30 to the choker valve of the carburetor.

What is claimed is:

1. In combination, a support, a rod having annular grooves slidably mounted in said deeply in the i support and a folded spring strip secured to said support and having projections formed therein adapted to engage said grooves.

2. In combination, a support, a rod having annular grooves slidably mounted in said support and a U-shaped spring strip having its ends secured to said support and its body portion apertured to receive said rod and having projections formed therein idapted to engage said grooves.

In combination, a support, a rod having annular grooves mounted for reciprocation in said support and a U-shaped retaining spring having projections adapted to engage said grooves.

l. In combination, a support, a rod hav ing annular grooves mounted for reciprocation in said support and a retaining spring apertured to receive said rod and having projections adapted to engage said grooves.

In combination, a support, a rod having annular grooves slidabl mounted in said support and a U shaped retaining spring apertured to receive said rod and having projections adapted to engage said grooves.

6. In combination, a support, a rod slidably mounted in said support and a spring apertured to receive said rod and prevent rotation thereof, said spring having projections formed therein adapted to yieldingl retain said rod in adjusted position.

7. In combination, a support, a noncircu lar rod slidably mounted in said support and a spring guiding means for said rod with a perforation therein slidably receiving said rod and conforming to the contour thereof to prevent rotation of said rod, said spring having a portion engaging the rod and yieldingly holding said rod in adjusted position.

8. In combination, a support, a guide, a valve control rod longitudinally movable through said guide and support, a perfo rated flat spring carried by said support in part parallel therewith and having portions extending from the support longitudinally of the rod and engaging said rod at a distance from the support.

9. In combination, a support. an adjusting rod projecting through and slidablv mounted in said support and noneircular in cross section and a spring provided with a perforation slidably receiving the rod and c0nforming to the transverse contour thereof to prevent rotation of said rod, said sprin having a projection engaging the rod and j'ieldingl retaining said rod in a longitudinally adjusted position.

10. In combination, a support, a rod slidabl passing through said support, and a folded spring strip secured to said support and having arms extending longitudinally of the rod from the support, said arms being provided with portions engaging said rod for 'ieldablv holding the rod against. sliding movement.

11. In combination, a support having an opening, a guide secured in operative relation to the opening at one side of the support, a rod slidably passing through the guide and opening of said support, and a spring secured to the support at the opposite side from said guide and having arms extending longitiulinally of the rod upon opposite sides thereof and having engage ment with the rod to yieldabl hold the rod against: sliding movement.

12. In a valve regulating means for carbureters of automobiles, a longitudinally slidable valve operating rod, a guide for sairl rod adapted to be secured to the outer laee of the instrument board of an automobile. in combination with a flat spring adapted for connection with the inner face of such instrument board. the spring being adapted to extend outwardly away from said instrument board and being adapted to grip said rod intermediate its length.

13. In eombimition, a support. a guide at one side of said support, a rod extending through the guide and support. a spring at the opposite side of said support having engagement with said rod to ,'l )ltl21l)l hold the rod in an adjusted position, and common means for securing the guide and spring to said support.

14. In a valve regulating device, a longitudinall slidable valve control rod, a perforated locking spring adapted to extend at each side of said rod and through which said rod is adapted to slide and by means of which the rod can be held in predetermined positions, in con'ibination with means adapt ed to support the rod and spring in cooperative relation on the inner face of an instrument board of an automobile.

In witness whereof I have hereunto set nrv hand.
