Description

Dec. 22, 1931. H. KAI 1,837,220
CONTROL DEVICE Filed March 7, 1930 [N VENTOR BY u Patented Dec. 22, 1931 UNITED STATES PATENT OFFICE LOUIS H. KAI, OF KALAMAZOO, MICHIGAN ASSIGNOR Tl SHAKESPEARE PRODUCTS COM- PANY, OF KALAMAZOO', MICHIGAN CONTROL DEVICE Application led March 7,
The main object of this invention is to provide a control device for choke valves for carburetors and other remote controls which is well adapted for retaining the parts in their adjusted positions.
A further object is to provide a structure having these advantages which is very simple and economical in its parts and the parts are so arranged and supported as to prevent rattling. y
Objects pertaining todetails and economies of my invention will definitelv appear from the description to follow. The invention is defined in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, in which:
Fig. 1 is a fragmentary view mainly in longitudinal section of a choke valve control embodying the features of my invention, the
section being on line 1-1 of Figs. 2 and 3.
Fig. 2 is a transverse section on line 2-2 of Figs. l and 3.
Fig. 3 is a plan view of one of the support members.
Fig. 4 is a face view of the finger piece.
Referring to the drawing, we -provide a tu bular support preferably made up of the section l externally threaded at 2 to facilitate mounting in an instrument board or the like of a motor vehicle. The section 3 is telescoped with the section 2, these parts being secured together and, in effect, constituting a single element made of sections for convenience in manufacture.
4 represents the sheath or housing for the push rod 5 leading to the part operated which is not here illustrated. The parts 2 and 3 of the support being of different internal diam eters provides the support with a stepped bore.
The headpiece 6 is reciprocatingly mounted in the support and is a sliding fit in the reduced section of the support, the rod 5 be ing arranged in a longitudinal bore 7 in the headpiece and secured therein by offsetting at 8. The headpiece is provided with a fingerpiece 9 preferably having the word Choke thereon, although it is to be understood that 1930. serial No. 433,885.
this legend would be in accordance with the part to be operated.
The headpiece 6 has a longitudinal groove 10 therein which is engaged by the bowed spring 1l.V This spring has a laterally turned end l2 engaging the radial bore 13 in the support, thereby anchoring the spring. The other end of the spring is in supporting engagement with the wall of the reduced portion of the bore,pthe spring being thus held under tension and also locked in position. The friction of the springv and the friction caused by the spring pressing the headpiece against the wall of the supportvholds the headpiece in its adjusted position and also prevents rattling. Further, the spring engaging the groove holds the headpiece against rotative movement so that the legend is properly presented.
The parts of my improved control device are very economical and very quickly and easilyv assembled. The spring is held in assembled position without riveting or otherwise securing than by engaging its laterally turned end in the hole 13 and inserting the headpiece.
I have illustrated and described my im'- provements in the form designed by me for use as a carburetor choke although it is adapted for use in various other relations. It is believed that suoli` other adaptations will be readilyunderstood by those skilled in the art to which the invention relates.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
l. A control device comprising a tubular support having a stepped bore and a radial bore in the wall of the larger portion thereof, a cylindrical longitudinally grooved head piece reciprocatingly mounted in said support and provided with a linger piece at its outer end, and a bowed spring disposed within said support in engagement with said groove in said head piece and having an outturned part at one end disposed in said radial bore in the wall of said tubular support, its other end being in engagement with the wall of the reduced portion of said bore, whereby said spring is retained in position under ten- 100 sion and said head piece is frictionally retained in its adjusted positions and supported against rotative movement and rattling Within the support.
2. A control device comprising a tubular support having a radial hole in the Wall thereof, a longitudinally grooved head piece reciprocatingly mounted in said support and provided with a finger piece at its outer end, and a bowed spring disposed Within said support in engagement with said groove in said head piece and having anv anchoring part at one end engaging said radial hole in the Wall of said tubular support, its Vother end having the upward movement thereof limited by the Wall of said tubular support.
3. A control device comprising a. tubular support having a stepped bore, a head piece reciprocatingly mounted in said bore and having a longitudinal groove therein, and a bowed spring disposed Within said bore in engagement with said groove With one end anchored to the Wall of the enlarged portion of the: bore and its other end having the outward movement thereof limited by the Wall of the reduced portion of the bore.
4. A control device comprising a barrellike sup-port, a head piece having a longitudin=al groove therein reciprocatingly mounted in said support, and a. bowed spring mounted Within said support to engage said groove and anchored at one end to the Wall of the support and having its other end in upward movement limiting Contact with the Wall of the support.
5. A control device comprising a barrellillre supportj a head piece reciprocatingly mounted in said support, and a bowed spring mounted Within said support to engage one side of sai-d head piece and anchored at one end to the Wall o f the support and having its other end engaging the inner surface of the Wall of the support.
In Witness whereof I have hereunto set my hand.
