ELECTRIC HEATING-PAD FOR CARBURETERS, 800.
Specification of Letters Patent.
Patented Aug. 14 1917.
Application filed February 14, 1917. Serial No. 148,485.
To all whom it may concern.
Be it known that I, RICHARD H. HUMITSCH,
a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Electric Heating-Pads for Carbureters, &c.. of which the following is a specification.
This invention. relates to electric heaters for carbureters, and has for its object to provide an improved device which can be quickly and easily applied to a carbureter for the purpose of heating the same and assisting vaporization therein, and it will be found particularly serviceable on carbureters using low grade hydro-carbons.
The heater comprises a band or pad adapted to be mounted on a carbureter, and it may be used on either the float chamber or the mixing chamber.
In the accompanying drawings- Figure 1 is a side elevation showing the heater applied to the float chamber of a carbureter.
Fig. 2 is a section on the line 2-2 of Fig. 1.
Fig. 3 is a detail in horizontal section of the heater.
Fig. 4 is a detail in vertical section thereof.
Fig. 5 is a diagram plan showing the wiring in the heater.
Fig. 6 is a top view of a modification, the pad extending only part way around the chamber.
Fi 7 is a fied orm.
Fig. 8 is a detail in perspective of the wire holder or frame shown in Fig. 7.-
The heater comprises a pad or band which is somewhat flexible, so that it may be placed around the float chamber of a carbureter as shown in Figs. 1 and 6. The pad comprises an outer layer or piece of asbestos 1, an intermediate layer of mica 2 and an inner layer of mica 6. The layers 1 and 2 are clamped together by channeled binding or edge strips 3, which extend along the upper and lower edges of the layers, and the inner flanges of these strips are provided with hooks 4. The insulated wire 5 is strung back and forth between these hooks, and is detail of the wiring in a modiinclosed between the mica layers 2 and .6. All parts are held together by edge binding strips 7 under which are strips of asbestos 8. The terminals 9 of the pad wire are connected by wires 10 and 11 to a battery 12, with a switch 13 in the circuit.
This pad is placed around the float or other chamber of the carbureter and will serve to heat the walls thereof. It may extend completely around the same, where conditions permit, as shown in Figs. 1 and 2, or partly around the same as shown in Fig. 6, and the pad is held in place by a flat spring clip 16.
In the modification shown in Figs. 7 and 8, the wire 5, instead of being strung over hooks 0n the edge strips, is strung back and forth between notches 15 in the edges of a plate or layer 14 of asbestos, which is inclosed between protective layers of mica as in the construction above described.
It will be appreciated that this heating pad can readily be applied to an existing carbureter, and will then serve to heat the walls of the float or mixing chambers and assist in the vaporization of the oil when the current is turned on. The device has the advantage that a special construction of layer of electric insulating material, said wire being inclosed between the said intermediate and inner layers.
2. An electric heating pad for carbureters, comprising layers of insulating material, a heating wire confined between the same, an outer layer of heat insulating material, and edge strips clamped over the edges and confining the margins of said layers.
In testimony whereof, I. do aflix my signature in presence of two witnesses.
RICHARD... H. HUMITSOH.
