1918. Serial No. 266,942.

- To all whom it may concern:

Be it known that I, ANTON I. SANDBO, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Vaporizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

The present invention relates to vaporizers, and this application is a division of the application for patent on Vaporizers, filed July 7, 1917, Serial No. 179,187.

It is the object of the invention to provide a novel vaporizer for attachment to an in ternal combustion engine, and designed for application to the intake manifold, thereby the vaporizer serves as a receptacle for fuel which when lighted will provide flames underneath the intakemanifold for the purpose of heating the walls thereof and the carbureted air flowing through the manifold to the engine cylinders. The vaporizer is thus useful for heating the air and hydrocarbon which flows through the intake manifold to the engine, thereby enhancing the operation of the engine and its efliciency, and also facilitating the starting of the engine in cold weather.

A further object is the provision of such a vaporizer comprising a very simple construction, which can be inexpensively manufactured, which willbe practical in use and which can be readily applied and removed.

The inventionis illustrated in the accompanying drawing, wherein Figure 1 is a side elevation of aninternal combustion engine showing the intake and exhaust manifolds with a pair of the vaporizers installed.

Fig. 2 is a perspective view. of a vaporizer.

Fig. 3 is a smaller view showing a variation in the supporting or suspending means for the troug Fig. 4: is a cross section showing the second form of vaporizer applied to the intake manifold.

The numeral 1 designates the intake manifold of the engine, through which the carbureted air flows from the carbureter to the engine cylinders, and the presentvaporizer which is used for heating the said manifold,

comprises an elongated trough or receptacle Qwhich is adapted to extend longitudinally below one horizontal arm of the manifold substantially parallel therewith. As shown, two ofthe Vaporizers are used; one underncath each arm of the intake manifold, and inasmuch as said devices are duplicates of one another, a description of one will suffice for both. 7

The trough or receptacle 2 is provided with means for suspending it underneath the intake manifold, and for this purpose the outer longitudinal side wall of the trough has an integral upwardly projecting tongue or'strap 3, which, as shown in Figs. 1 and 2, has an aperture 4 at its upper end to engage 'one of the stud bolts 5 that are used for clamping the manifolds to the cylinders, said tongue or strap being clamped in place by the nut on said bolt, so that the tongue suspends the trough in proper position. The lower end of the tongue 3 is inclined, as at 6, so as to offset the trough 2 inwardly to a point underneath the manifold 1 in the vertical plane of its axis. The trough 2 is preferably filled with asbestos or other similar absorbent noncombustible material so that alcohol, oil or other liquid fuel poured into the trough will be absorbed by the filler which will serve as a wick and the fuel in being lighted will burn with a steady flame. Due to the elongated form of the trough or receptacle, the flame will extend longitudinally along and underneath the respective arm of the manifold 1 so that its walls will be heated by the flames rising against the bottom of the manifold and passing upwardly across both sides thereof. As a result, the mixture of air and. hydrocarbon flowing through the manifold will be heated effectually, so that the engine will start easily, and operate with added efficiency.

In the modification shown in Figs. 3 and 4; the tongue or strap 3' is bent into loop form so as to arch over the trough, and the tongue thus forms a resilient clamp extending through an arc of over 180 degrees. The tongue is thus capable of being snapped down over the intake manifold 1, as seen in Fig. 4:, and the tendency of the loop or clamp to contract causes it to tightly embrace the manifold and maintain itself in the proper position after once being applied and adjusted. The lower portion of the tongue is inclined, as at 6", between the trough 2 and loop, so

' and detachment of the vaporizer,

on the stud bolt that is used for the attachment of the vaporizer.

Having thus described the invention, what is claimed as new is A' vaporizer for attachment to the manifold construct'on of an internal combustion engine at either side of the intake manifold, comprising an elongated narrow fuel holding trough entirely open at the top from one end to the other, for holding absorbent noncombustible material. and fuel, and to be diseither side of the manifold, said tongue extending outwardly and upwardly to extend across the intake manifold and having means at its upper end for the attachment to the manifold construction.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnessses.
