HEATER FOR INTAKE MANIFOLDS OF INTERNAL COMBUSTION ENGINES.

Specification of Letters Patent.
Application filed May 28, 1917. Serial Ei e. l'ilyi'lfi.
To all whom it may concern:
Be it known that I BERT N. Penman, a citizen of the United states, residin at the city and county of Jackson and S tate of Michigan, have invented certain new and useful Improvements in Heaters for Intake- Manifolds of Internal-Combustion Engines, of which the following is a specification.
This invention relates to improvements in heaters for intake manifolds of internal combustion engines. I
The objects of the invention are:
First, to provide a heater for the intake manifold of internal combustion engines which is simple in structure and economical to manufacture.
Second, to provide a heater for the manifold of internal combustion engines in which the heat generated is efliciently transmitted to the walls of the manifold.
Further objects, and objects, relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and ointed out in the claims.
A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:
Figure I is a side elevation of a portion of the intake manifold for an internal combustion engine showing the manner of applying my invention thereto and the connections therefor, together with a controlling switch on the dash of an automobile.
Fig. 11 is an enlarged detail section taken on a line corresponding to line 2-2 of Fi I.
Fig III is an enlarged detail section taken on a line corresponding to line 33 of Fig. II.
Fig. IV is a bottom view of theheating element employed in, my heater, thelower sheet of insulation bein removed.
Fig. V is a diagram sowing the 66112166 tions between the heating elements of my heater, the source of current and the switch.
In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
Referring to the drawing, the inference character 1 indicates a portion of the intake manifold of an internal combustion engine. in practice i prefer to thicken. the walls of the conduit which leads from the carburetor as indicated at 2 to provide walls of suflicient thickness to allow the forming of recesses therein for receiving the heating elements. As shown in Figs. 11 and HI these recesses 3 as illustrated extend lengthwise of the in; take conduit at and are substantially rectangular in outline and provided with flat bottoms.
The heating element comprises the cover plate 5, the top insulation 6, the resistance element 7 and the bottom insulation 8. Binding posts 9 are secured to each end of the resistance element and project through suitable apertures in the top insulation and the cover late. The end of the resistance element, t e top insulation and the cover plate are clamped together by means of the nuts 10 and the binding post 9, an insulating washer 10 being interposed between the nut 10 and the cover plate 5. The ends of the cover plate extend'heyond the adjacent ends of the heating element and are secured to the manifold by means of the screws 11. The connections for my improved heater are diagrammatically illustrated in Fig. V in which the reerence character H indicates the two heating elements on the opposite sides of the manifold and the reference S indicates the source of current which, as shown, is connected in series with the two heating elements and adapted to be disconnected therefrom by a switch 12 which, as shown in Fig. I, may be mounted upon the dash or any other suitable part of the car.
The operation of my improved heater will be readily understood from the above description. When it is desired to start a car equipped with my heater it is merely necessary to close the switch 12 whereupon the heat generated in the resistance element 7 will be transmitted to the walls of the intake manifold and heat the same suflici-ently so that the fuel in the charges drawn therethrough is effectively vaporized thereby expediting starting of the motor. By placing heating element in recesses in the walls of the manifold l obtain an efiicient transmission, or transfer of heat, from the heating elements to the walls of the intake manifold and there is not so great an opportunity for the radiation of heat as "p 2536 111 221115 fer insulating said resistance e'ieiiiem LI'OR- said. cover plate and the Walls my; 6km
