Description

Patented Nov. 8, 1932 CLAUDE 0. WESTOVEB, OF ORLANDO, FLORIDA CARBUBETOR Application led July 14, 1930. Serial No. 467,877.

This invention relatesto a carburetor, the general object of the invention being to provide means whereby a motor will function properly during the warming up period so that the vehicle can be driven away instantly with power and speed without having to wait for the engine to warm up, thus saving annoyance and time, and the invention will also prevent upper cylinder and valve lubricant 1 dilution, fouling of the spark plugs and back'- ring and resultant fire hazard, during this period.

. This invention also consists incertain other features of construction and in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim. n

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like' or corresponding parts throughout the several views, and in which Figure 1 is a view of a further modification. Figure 2 is an edge view of certain of the parts shown in Figure 1. p

Referring to the drawing in detail there is shown a throttle lever 13 which is of substantially L-shape, with its long arm terminating inahook part 14 which is fastened to the shaft 15 of the throttle valve 16. This long arm has an elongated slot17 therein and the link 18 is connected with the extremity of the short to the actuating means for the throttle valve. An arc shaped lever 19 is pivoted at 20 and has an' arm 21 thereon to which the pull rod 22 is connected. The curved part of the lever has an elongated slot 23 therein and the bent end of a link 24 passes through the slots 17 and 23, the other end of the link being connected to the arm 25 of the choke valve 26. Thus when the pull rod 22 of the choke is operated to close the choke, the upward movement of the curved lever 19 will exert a pull upon the link 24 so as to close the choke valve and' this movement raises the bent end of the link in the slot 17 so that when the throttle lever 13 is swung downwardly to open the throttle, the link will be caused to move the arm of the lever,this link being also connected choke valve to open position, as shown in dotted lines in Figure 1. When the choke valve is in its open position, the bent end of the link will be at the lower end of the slot 17 so the throttle lever can be moved to open and close the throttle valve without changing the position of the choke valve and its associated parts. The parts in this form of the invention are so constructed that the choke valve always opens in less proportion to he throttle valve as the choke is being use As will be seen, this invention acts to first choke the air supply and then allows more air withmore throttle and less air with less throttle.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the ,construction and in the combination and arrangement of the several parts,

provided that such changes fall within the scope of the appended claim.

The combination with a carburetor, of a choke valve therefor, a throttle valve for said carburetor, an inverted substantially L- shaped throttle lever having a slotted long arm provided with a hook terminal connected with the axis of said throttle valve, an operating link connected with the short arm of said lever, an arcuate-shaped member pivoted for movement and having a slot, a crank on the choke valve, a link pivoted to the crank and having a rightangularly bent end passed through the slot in the arcuate-shaped member andsaid leverand an actuator rod connected with said arcuate-shaped member for moving the same.

In testimony whereof I affix my signature.
