This invention relates to a hot spot manifold adapted to be used with an internal combustion engine on an automobile over which a current of air flows from the front 5 to the rear. The object of this invention is to provide heating means whereb the rate of heating up of the inlet manifo (1 may be hastened, and to provide semi-thermostatic means which will automatically prevent the inlet manifold temperature rlsin to such a figure as will materially reduce t e power.
It is understood of course that no attempt is made to keep the mixture temperature even approximately constant as it is doubtful whether it is desirable to have an absolutely constant temperature, and in any event this invention does-not produce that result.
Figure 1 shows the device in elevation.
Figure 2 shows a cross sectional elevation of lane 2-2 of Figure 1.
Figure 3 shows a partial section elevation taken on the plane 3-3 of Figure 2 showing the thermostatic element.
Figure 4 shows the manifold mounted on an engine having the usual radiator and cooling fan.
In-the figures, A is the exhaust manifold having the outlet B to the rear, a current of air flows from the front of the exhaust manifold A- to the rear, flowing from the radiator (not shown) being propelled by a fan (not shown). The arrows in Figure 1 indicate this flow of air over the exhaust manifold B. C is the inlet manifold having a flange D to which a carburetor of any well known type is adapted to'be connected. E is a valve in the exhaust outlet B, mounted on a shaft F to which is connected a link or crank G which is connected through a link H with a lever arm J, K (Figure 3) is the thermostatic element riveted to the lever J and connected to the shaft L, the thermostatic element is partly enclosed by a casing or cover M, this casing M is anchored to the inlet manifold C by the screws N-N. The a.
shaft L is threaded into the cover M and locked in place by the lock nut O. In order that the valve E can be assembled in the exhaust manifold A a cover P is provided which is held in place by 3 cap screws. The
inlet manifold C is provided with a jacket Q which communicates with the exhaust manifold A. The exhaust enters the jacket Q through an opening R in the exhaust manifold A. The inlet manifold C is bolted to the exhaust manifold by means of thecap screws U-U, a gasket being used to prevent leaka S is a tube forming an outlet from the acket Q this tube communicating with an opening T in the outlet B of the exhaust manifold. 'The openingT is adapted to be closed b the valve E when E is rotated in a c ockwise direction from the position shown in Fi re 1.
When the automobi e to which the device 1s applied, is started and the temperature of the air fiowinglover the exhaust manifold is below 90 F. t en the valve E is in the'posi-- tion shown in Figure 1. The minute the engine begins to fire the exhaust gas escapes via the assa RQST to the exhaust outlet B and e wa ls of the inlet manifold C are therebg heated. Heat immediately flows from through the casing M to the thermostatic element K contained therein. As this 1 element K is made of two metals welded together the coil of metal unwinds and the lever J is rotated in an anti-clockwise direction about the center of the shaft L to which the element K is anchored. The shaft L is threaded into M and is locked in place by the lock nut O. The temperature at which the lever J begins to move the valve E is therefore determined by the position to. which the shaft L is turned when the nut O is locked in place. The anticlockwise rotation of J turns the valve E in a clockwise direction, first opening the exhaust manifold A so as to permit some of the exhaust to esca direct to B and finally closing the outlet from the pipe S, thus forcing all the exhaust gases to flow directly to the exhaust outlet B.
