HEATER ron AuroMoisILn ENGINES;

Application filed April 9, 1927. Serial No. 182,451.

This invention relates to improvements in heaters, particularly in connection with automobile engines.

A prime object-of this invention is to provide a heater, simple of construction and easily applied to the desired part of. an automobile engine, in order to keep the motor warm and easy to start, particularly in cold weather, the register of the heater beingadaptedto be placed approximately under the base ofthe engine in the center.

Other objects of this invention will appear from the following detailed. description of the device and as disclosed in the single sheet of drawings herewith made a part of this application.

In the drawings- Figure 1 represents a perspective view of the heating device with its different elements in assembled relationship.

Figure 2 illustrates a vertical sectional 7 view of the heater.

Figure '3 represents a sectional view on lin 33 of Figure 2 on an enlarged scale, of the main end of the heater. 7

-Figure 4 represents a sectional view of the heater taken along line 4-4 of Figure 2.

Numeral 1 designates the main portion of the heating device which maybe termed a burner box, adapted to receive therein a gas burner 2 or other suitable source of heat, the gas entering the burner 2 in this instance through a fitting 3 connected to the source of fuel or gas supply. The container or burner box 1 may be made of any suitable material,such as sheet metal, and is adapted to be connected in open communication with a register box 4 by means of a suitable pipe element 5. The. opening 6 in the burner box '1 for receiving one end of the pipe element 5 is preferably located near the lower edge of one side wall; the opening 7 in the register box 4 for receiving the opposite end of the pipe element 5 is located near the upper edge of one of the sides, thereby forming a heating device in which the heat generated from the gas connect-ion 2 or other source will flow slightly upwardly through the pipe element 5 into the register box 4 and thence from the opening 8 in the upperportion of the register box 4, to the operating part of the engine, which it is desired to keep warm for easily starting in cold weather. The pipe element 5 may be made of any suitable material, such as sheet metal, and consists of sections adapted to be telescopically connected together as at 9 and 10 in order to allow for increase or decrease in length of the pipeelement 5. The burner box 1, register .box 4 and pipe element 5 may be con nected together in any practical manner, such as by soldering or preferably by flange portions as disclosed in the drawings at 11 and 12, the flangesbeing properly riveted to the cooperating sides of the box elements.

, In order to increase the heating efficiency, and eliminate,as far, as possible, the loss of heat, an insulation 13, such as asbestos, may be placed around the pipe element 5 and clamped inposition by means of elements 14, 15 and 16..

In the construction of the burner box 1 it is preferred to provide an opening 17 which is'adapted to be covered as at 18 with a fine mesh removable wire cloth, preferably brass cloth. This fine mesh cloth may be located .at any suitable point near the top of the burner box 1 andthe opening 17 thereof. The heater box 1 may also be provided with a removable cover portion 19 allowing, however, at all times, a sufficient air circulation for the purpose of the proper burning of the gas jet or other source of produce the heat required for warming the operating parts of the motor.

What I claim is 1-. A heater for maintaining the operating parts of engines on motor cars warm and easy to start in cold weather, consisting of a burner box provided with heating means, a register box, and a pipe element arranged in open communication between the burner box and register box.

2. A heater for maintaining the operating parts of engines on motor cars warm and easy to start in'cold weather, consisting of a burner box provided with heating means, a register box, and a pipe elementarranged in open communication between the burner box and register box, the ipe element be ing arranged to enter the urner box near .iii

the bottom thereof and the register box near the top edge thereof, thereby providing an upward flow chamber for the heat between the two boxes.

3. A heater for maintaining the operating parts of engines on motor cars warm and easy to start in cold weather. consisting of a burner box provided with heating means, a register box, and a pipe element arranged in open oon'inninication between the burner box and register box, the pipe element being arranged to enter the burner box near the bottom thereof and the register box near the top edge thereof, thereby providing an upward flow chamber for the heat between the two boxes, both the burner box and the register box having an oi iening in the upper portion thereof.

t. A heater for maintaining the operating parts of engines on motor care "arm and easy to start in cold weather, consisting of a burner box provided with treating means, a register lJOK, and a pipe element arranged in open communication between the burnerbox and register box, the pipe element being arranged to enter the burner box near the bottom thereof and the register box near the top edge thereof, thereby providing an upward flow chamber for the heat between the two boxes, both the burner box and the register box having an opening in the upper portion thereof, the opening in the burner box being adapted to be covered by a suitable fine niesh wire.

5. A heaterfor maintaining the operating parts of engines on motor care warm and easy to start in cold weather. consisting of a burner box provided with heating means, a. register box, and a pipe element arranged in open eonnnunioation between the burner be); and regieter box, the pipe element being arranged to enter the burner box: near the bottom thereof and the register box near the top edge. thereof, thereby providing an upward flow chamber for the heat between the two boxes. both the burner box and the register box having an opening in the upper portion thereof, the opening in the burner box being adapted to be covered by a suitable fine mesh wire, the pipe eleniont consisting of sections telescopically arranged for the purpose of adjusting the length and insulating nniterial surrounding the pipe.

In testimony whereof l atlizt my signature.

ALBERT l-IAZEN EAR-GENT.
