FOOT-'WARMING RADIATOR FOR AUTOMOBILES.

Specification of Letters Patent.

Application filed December 26, 1907.

Patented Aug. 24, 1909 Serial No. 408,098.

To all whom it may concern:

Be it known that I, EDWARD M. FIELD, Jr., a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Foot- Warming Radiators for Automobiles; 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 make and use the same.

My invention has for its object to provide an improved foot warming device for automobiles or other-engine-propelled vehicles, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In applying my invention to a vehicle 1 warmer, in total or in part, is caused to serve as a heat radiator or cooling coil for the cooling water or liquid.

-1 When the improved foot warmer is applied to a vehicle having an air cooled ex plosive engine, the hot exhaust products of combustion from the engine may be utilized to afford the heat required in said foot warmer. When the said foot warmer is appliedto a vehicle driven by a steam engine the exhaust steam may be transmitted through the foot Warmer, and the heat,-usually wasted in the exhaust, there utilized.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation, with some parts broken away and some parts sectioned, showing my improved foot warmer applied to an automobile of standard construction. Fig. 2 is a view partly in plan and partly in horizontal section, taken a proximately on the line m x of Fig. 1. ig. 3 is a detail partly in plan and partly in section, showing on an enlarged scale one ofthe swivel joints that connect the so-called radiator coil to the water circulating pipes; and Fig. 4 is a of a pair explosive engines to the ordmary cooling coil and to the radiator coil of, my improved attachment.

The numeral 1 indicates the body of an automobile of standard construction, the same having the customary removable floor section 2 in front of the seat. In a very large number of these automobiles the explosive engine which is carried by the running gear (not shown) is located under the vehicle body directly below the removable floor section 2, and ready access, for the purpose of adjustments or repairs, may be had to the engine, when said floor section 2 is removed. In applying my improved foot warming device to an automobile of this character, the foot warming radiator coil 3 is referably made with manifolds arranged to lie flatwise and in c lose engagement with the upper surface of the displaceable floor section 2, and the ends of this radiator coil are connected to the water circulating pipes 45 that lead, respectively, to and from the water jacketing chambers of the engines 6, of which latter, as shown in Fig. 4, there are two. The numeral 7 indicates the customary cooling coil, usually arranged in the hooded front end of the vehicle body 1, and through which the cooling water, in the customary arrangement, is circulated. The f numeral 8 indicates the usual steering rod of the machine and ,which is capable of the.

customary forward pivotal movement.

One of the principal features of my invention consists 1n connecting the foot warming radiator coil 3 in such manner that it may be raised or moved into an inoperative osition and thereby permit of the remova of the floor section 2, whenever it is desired to obtain access to the engine located below the said floor section. The said radiator coil may be thus connected through swivel. joints,

' artlculated metal joints, or flexible hose connectionswhich do not require a separation or disconnection between the coil and its cirou lating pipes, but which permit the required movement of the said co to and from o erative position. The best arrangement, ow-

ever, is shown in the drawings, and consists in connecting the ends of the coil 3 by liquidtight swivel joints to branch pipes 9 and 10 of the circulating pipes 4 and 5, res ectively. These swivel joints, as shown, are ormed by threaded collars 11 and 12. The collars 11 have threaded engagement with the ends of the cooperating branch pipes 9 and 10 and have ground seats '1-3'of the said coil 3. The collars. 1.2, which are clampingcollars, have screw-threaded engagementv with the cobperating collars 1'1 and Work ivotally on the shouldered ends13 oi the-.sai pipe coil, all asbest shown, in Fig.

.3. The two swivel joints thus formed are axially alined so that the pipe coil" 3 may be readily turned upward into the position shown by dotted lines in Fig. 1, it being necessary, of course, to first force the ointed steer mg rod S'forward; This connection, as is evident, while it always maintains a liq,- uid-tight-joint, permits the radiator coil to be quickly'turned upward into an inoperative osition andito be again turned backward mtoan operative position.

At the junction of the pipe 5 with the branch is a three-way valve 14' of the usual or any suitable construction, and by means ofwhich, at will, the circulation of the water may be directed onward through the said'pipe 5 and usual cooling coil 7 back to the engines, or may be cut off from said coil 7 and directed through the branch pipe 10, through the warming radiatorcoil 3, branch pi e 9 and pipe 4 back to the engines.

. y setting the three-way valve 14 in an intermediate position, part of the heated cooling water may be directed through the coil 3, and part thereof through the coil .7, so that a variation of temperature of the said footwarm-ing coil'3 is made possible, to thereby adapt the same to different conditions of the weather.

I believe it to be broadly new to ro'vide a foot warming or similar heating coi or radiator which is capable of movements to and from operative positions without disconnection from the circulating pipes which supply the heating medium thereto, and desire to claim this feature broadly.

It,1s, of course, evidentthat when the socalled foot warming device above described is to be appl edto a, vehiclehaying two or medium circulating lating pipes extending to and from said em gine, t e body of said vehicle having a dish laceable floor'section in front ofits seat, 015 a oot warming radiator coil or manifold pipe section normally located immediately above the said displaceable floor section and. connected to said circulating ipes, by means ermitting said radiator to rom operative position, while connected to said circulating pipes, substantially as de scribed.

The combination with a vehicle having a propelling engine and circulatingpipesfor the cooling Water or fluid, including aprimary cooling coil or radiator and branch cir- 'culating pipes, the body of said vehiclehavmg a displaceable floor section in front of its seat, of a three-way valve located at, the junction of one of said branch pipes to one of the main circulating pipes, and a foot warming coil or radiator connected to said branch pipes by means permitting said latter radiator to be moved to and from o erative posi tion while connected to said ranch p1pes, substantially as described.

I In testimony whereof I afiix my signature in presence of two witnesses.
