Application filed April 1,
Reference is 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.
In said drawings:

taken on line 1-1 of Fig. 2, with parts broken away; r
Fig. 2 is a fragmentary top plan view of my improved exhaust heater valve operating mechanism and having parts broken away;
Fig. 3 is a fragmentary top plan view illustrating a crank handle associated with the valve operating mechanism; and
Fig. 4 1s a horizontal sectional view, taken on line 4-4 of Fig. 1.
My invention relates to exhaust heater 5 valves, and has particular reference to anoperating mechanism therefor.
The invention has for its principal ob]ect the provision of an exhaust heater valve opcrating mechanism, wherein a plurality of valves are actuated either to open or closed position simultaneously, and are so arranged as to compensate for one valve moving in advance of "another and thereby cause all of them to move in synchronism.
A further object of the invention is to provide a valve mechanism of this character which is compact, simple in construction, and which is free from vibrationeven though the valves are in a partly open position.
' Referring to the invention in detail, the numerals 5 and 6 designate a pair of internal combustion engine exhaust pipes for com munication with mufiiers 7 by means of casings 8. Supported transversely on each of these casings 8 and communicating therewith, is a passageway or conduit'9, with the outer end of each of which a branch pipe 10 communicates, the latter leading to ex-' haust heaters (not shown) of an automobile.
A valve 11 is provided in each of the casings 8 to direct the passages ofexhaust gases either to the mufflers or branch pipes 10. As shown in Figure 2, these valves are fixed to rock shafts 12 journaled in the casings 8, and the 1927. Serial N0. 180,184.
of the exhaust pipes 5 and 6. -A bell-crank lever 18 is pivoted to the bracket 15 as at 19. A longitudinally movable actuating rod 20 has its forward end pivotally connected to the lower end of the bell-crank lever 18 as at 21, while its opposite end carries a yoke or clevis 22. A transverse equalizer bar 23 extends horizontally through the yoke or clevis and is supported therein for pivotal movement about a vertical pin 24 passing through the clevis or yoke. Normally parallel arms or levers 25 are fixed to the projectingends of the rock shafts 12 and have their upper ends pivotally engaging the extremities of the equalizer bar 23.
Countersunk in a recess 26 in the automobile fiooring 16 in vertical alinement with the lateral leg of thebell-crank lever 18, is a socket 27, having a central opening 28 in its bottom. A vertically arranged adjusting screw 29 passes through the opening 28 and is formed with an annular shoulder 30 resting upon the bottom of the socket 27 to retain the screw 29 against movement in a downward direction. A stop washer 32 is received on the screw slightly below the socket and serves to retain the former against upward movement, the stop washer being held in position by lock nuts 33 engaged with the screw. As shown in Figure 4,.the lateral leg of the bell-crank lever 18 is formed with a pair of parallel ears 34 in which a cylindricalmember 35 is journaled. This member 35 is formed with an interiorly threaded vertical bore 37 through which the bolt 29 passes and engages. A rectangular head 39is formed on the upper end of the screw 29 and is adapted to be engaged by a detachable crank handle 40 when it is desired to'rotate the bolt and hence actuate the valves 11.
When it is desired to actuate the valves to a position to establish communication between the exhaust pipes and their mufllersand sever communication between the exhaust pipes and branch pipes 10, the screw is rotated by means ofthe crank handle 40, to rock the bellcrank lever 18, operating the rod 20 to the 1 dot-ted line position. 'When it is desired to establish communication between the exhaust pipes and branch pipes 10, the valves are actuated tothe position shownin Figure l by .rotating the screw in the reverse direction. will be observed that the valve can be adjusted to a partly open position by r0- ,tating-the screw to dispose thevalves at a predetermined point. As heretofore mentioned, the levers 25 secured to the rock shafts 12 have their opposite ends pivotally connected to the equalizer bar 23. This construction has been adopted for the purpose of providing a certain amount of relative movement'between the rock shafts 12 to compens ate for differences in tension -of the springs whereby the valves 11 will be each forced to fully closed or open position, and it will-be apparent that if the lever 18 isajctuated to place the valves 11 infully open position as shown in Figure 1, and the tenslon of the springs 50 is not equal, one of the valves 7 will reach fully open position in advance of its companion valve. The equalizer barwill have assumed aniangular position. Further actuation of the'leve'r Wlll cause the other valve to assume fully open position because of the equalizer bar.23.- The same operation will-occur to seat thevalves in fully closed connecting said. valves, a lever pivoted inter- V mediate itsfends andhaving operative engage- 'Inent withthe connecting means, and a manm 'allyoper-able threaded element engaging the {lever to adjust the latter about its pivot and thereby simultaneously actuate the valves.
