ELECTRIC OAR-HEATER.
Specification of Letters Patent Patented NOV. 29, 1921.
Application filed July 2, 1919. Serial No. 308,151.
To all 20 710m it may concern Be it known that I, LEE P. IIYNES, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Electric Car-Heaters, the following being a full, clear, and exact disclosure of the one form of my invention which I at present deem preferable.
For a detailed description of the present form of my invention, reference may be had to the following specification and to the accompanying drawings forming a part thereof, wherein- Figur 1 shows the car-seat and flue in section and the heater in elevation;
Fig. 2'shows a two-heater arrangement;
Fig. 3 is a plan view;
Fig. 4 is a side elevation.
In an application for patent filed herewith (Serial Number 308,150), I have shown and described a system of car heating wherein the individual heater-elements are adjusted in resistance to the trolley-line voltage and therefore constituted of fine w 1re embedded in insulation. In connection wlth such elements, which are fiat in form and only about one-half inch in thickness, I provide a guard-sheet around each element but spaced away therefrom. This guard-sheet constitutes an unobstructed inclosure or flue that replaces the usual box or having perforated sides, such as are necessary in the present form of car-heater to avoid electrical contact with the bare, exposed heater Wires, but which prevents free flow of the air through the heater into the car thereby greatly retarding ventilation of the heater coils. By my system I am enabled to use one identical heater-element for all types of car with a large saving in expense as well as in cost of the heaters. I also secure a more rapid and efiicient distribution of heat to the car with resulting relief of the heaters. In the present application I describe and claim a form of heater arrangement characteristic of the new system of car heat ing aforesaid as the same is combined with a car-seat.
Referring to the drawing, 6, 6 represent the front and rear sills of a car-seat that ex tends transversely with respect to the car. The sills 6, 6 are of angle form and to the horizontal branches of the two angles I attach a metal sheet 13. which extends across between the two sills but is depressed at the center. This sheet forms a transverse deflector plate with a double incline.
To the under side of sheet 13 I attach a hanger'l l which supports a trolley-voltage heater of the type aforesaid and at the same time serves as a guard-sheet such as I have heretofore mentioned. In Fig. 2 I have shown two such hangers, one on each of the two oppositely inclined portions of the sheet 13. The heater element consists of a flat body of insulation 1 which is incased by a skin of metal and in which the fine-wire heating coil (not shown) is embedded such a heater element radiates the heat from its extended outer surface and not from the heater-wire itself. The ends of the heater wire are brought out to suitable terminals 2, 2, on the upper side of the element, the metal skin being cut away to allow these terminals to be seated on the insulating material. The heater element is positioned about in the middle of the space or compartment embraced by the guard-sheet hanger 14, being so stationed by means of feet 5, 5 (see Fig. 4) which are formed by turning down the ends of the metal skin which incases the insulating body of the heater element as is best shown in Fig. 4. The bottom of the hanger 14 is open so that the air may rise up through it at or near the center and after passing in both directions around over the radiating surface of the heater element emerge on each side of the hanger into the interior of the car. In the modification shown in Fig. 2 the cool air enters between the two heater elements and divides, going in both directions and both over and under the two elements to its delivery points under the respective seat sills 6, 6. The heater element in both forms is thus in the center of an air flue into which the cool air enters and from which the hot air emerges, the air current flowing parallel to the radiating surface and the heater element standing edge- Wise to said current, particularly in Fig. 2. By this arrangement I provide the several features which characterize my car-heating system aforesaid and attain the particular advantage of occupying only a limited amount of vertical space beneath the car seat. This is indicated by the location of the foot- rest tubes 7, 7 which show the amount tal,thereby occupying a small amount of space vertically, and imparting the samequality to the device as a whole including the flue in which the elernent is located.
What I claim is new and desire to secure byLett-ers Patent is:
l. A heater of the character described.
comprising a flat heater element having a heater Wire embedded therein, and a guard sheet supportlng sald heater I element, said guard sheet having portions surrounding a said heater element but spaced therefrom to provlde an unobstructed a r flue'opening into flat heater element having a heater wire the space to be heated. V
2. A heater'of the, character described comprising a flat heater element having a V Jheater wire embedded therein, and a guard sheet supporting said heater element, said guard sheet having.v portions surrounding said heater element but spaced therefrom to provide an unobstructed air flue opening into .the'space to be heated, said heater element being positioned insaid flue edgewise to the a air current.
3.1K" heater comprisinga flat heater element having a heater wire embedded therein, and a guard sheet supportin'gsaid heater element and inclosing the same on three sides and spaced therefrom, said guard sheet forming an air flue, said heater element being positioned in said flue edgewise to the air current. V
eL;A.,.heater of the character-describedcomprising ajflat heater element, having a. heater wlre embedded there n, inclosing walls supporting saidheater element and forming a flue in which saidheater element is positioned'edgewise to the air, current, and
an inclined plate? above said heater element and spaced therefrom, said inclined plate The heater elements are of the character described flat horizontallheate'r element, a deflector late below the seat and above said heater element, and an air flue incloslng and supporting said heater element with its radiating surface parallel to the direction of travel of the air current in the flue.
6'. The combination with a car seat of a flat heater element having a heater Wire embedded therein and also having a radiating surface separate from the heater wire, and
a flue extendedtransversely of the seat and supporting said heater element, said flue being open at both ends.
7. The combination with a car seat of a embedded therein, and a radiating surface separate from the heater wire, a deflector plate extending transversely beneath the seat and above said heater element, and a guard sheet supporting said heater element and parallelth erewith forming a flue extending;
comprising'a heater element having a radiat- 1 lng surface separate from the heater wire, a
flue inclosing and supporting said heater element, said flue having an opening to receive cold air a'ndan opening to deliver heated air, and a deflector plate above said flueand said heater.element. v
