' ELECTRIC HEATER.

Specification of Letters Patent. Patented April 23, 1907.

Application filed May 4;, 1906. Serial No. 315.146.

Be it known that I, EDWARD E. G013, a

borough of Manhattan, city, county, and State of New York, have invented certain Heaters, of which the following is a specifica- My invention aims to provide certain improvements designed for coverlng and proelectric heaters and the mains. For this purpose I provide an electric car-heater having a chamber which constitutes a junctionbox for inclosing the ends of the line-wires leading into the heater. The wallof the junction-box is preferably provided with a socket which receives the end of a conduit inclosing the line-wire, so that the wire is entirely inclosed throughout thecar, increasing greatly the protection against fire and improving the appearance.

The accompanying drawings illustrate ap plications of the invention to a variety of heaters.

Figure 1 shows in plan a pair of Gold standard electric heaters arranged under car-seats of a car. Fig. 2 is-an end elevation of one ofsuch heaters in position, the heater shown being supposed to be at-the end of the car. Fig. 3 is a horizgntal section through one of the heaters and the junction-box. Fig. 4 is a horizontal section of the same at a lower point. Fig. 5 is a side elevation of one of the junction-boxes. Fig. 6 is an end elevation of the box. Fig. 7 is a plan of a pair 'of heaters, witha common junction-box. Fig. 8 is a horizontal section through such junctionbox. Fi 9 is a rear view of a style of heater adapted or attachment to the risers of longitudinal car-seats. Fig. 10 is a plan thereof, showing the riser in section. Figs. 11 and 12 are similar view's with the heaters so close together that the junction-box extends from one heater to the next without the interposi- Fig. 13 is a vertype adapted for attachment to the trussplank of the car. Fig. 14 is a horizontal section of the same. Fig. 15 is in art a front elevation and in part a vertical ongitudinal vThe-junction-boxes are all shown with the Gold type of heaters; but they may be used with various other types. Referring specificthrough which the bolt G passes.

trated in Fig, 1, single heaters A are arranged one under each of the seats B of the car and are connected to each other by wires carried through conduits O, of iron or other suitable material. Where the wires run into or out of the heater, a junction-box is provided, which I designate as a whole by the letter D.

In the single round heaters (shown in Figs 1 to 5) the junction-box 'is a round casing E, of

cation of the clamping-nut J and set-nut K.

A sheet L, of asbestos or of similar refractory material, is preferably introduced between the unction-box and the head F of the heater to serve as a fireproof packing. The junction-box has projections a a, which enter recesses a a, Fig. 5, in the porcelain head F to prevent the heater from turning relatively to the box.

In the heater shown in Fig. 3 the electric connections are made above the central point The heater shown utilizes two coils ,\one above the other, supported on rods extending between heads F and F. Only the uppermost coil is shown. This coil M is supported upon a sinuous insulating-rod N and is connected at one end to a binding-post O and at the opposite end to a return-rod P. The binding-postO and return-rod P project into sockets Q in the outer end of the porcelain head F and are provided with suitable Washers andclamping-nuts for-clamping the =ends of the wires R, which then pass out through'the asbestos end plate L and constitute the eifective ends of the heater-wires, to which the main or line wires are to be connected.

The junction-box E is provided with sockets for receiving the ends of the conduits C.

There'may, for example, be a 'number of sockets S on the endfour in the case shown, Fig. 6to receive two incoming wires and two outgoing ones and with a socket T on the under side for receiving the end of a conduit U, which extends downward below the floor of the car. Usually the boxes are man dicated by the arrows.

ufactured with the five sockets described, so that they may be used for making connections to the end heater through a conduit, such as U, Fig. 2, and for making connections between successive intermediate heaters in the manner shown in Fig. 1. The sockets S are of such size as to receive the ends of the conduits C and are pl'twided'with shoulders V, which limit the inward movement of the conduits, and with clampingscrews W, Fig. 5, which hold the conduits in position.

The main or line wires X are extended somewhat beyond the ends of the conduits and are bared, the usual flexible insulation Y being removed, and the ends of the wires X are then twisted or otherwise connected with the ends of the heaterwires R. .In order to have access to the interior of the junctionbox, a cover-plate 71, Figs. 5 and 6, is provided, fastened by screws (1?. The removal of the cover-plate opens an. entire side of the j unction-box and leaves plenty of room for the necessary manipulations. Openings I) are provided on the inner end of the junction box for passing the wires K into the box, these openings being separated by the bridge H.

Where the heaters A A are used in pairs, as in Figs. 7 and 8, the wires lead into the heater A at its inner end, then out of the heater A and into the heater A at the outer ends of the heaters, and thence out from the inner end of the heater A in the manner in- The heaters being anranged close together, one junction-box D is arranged to extend over the adjacent ends of two heaters. The casing c in this case is oblong and is provided on its inner end at with projections e, fitting in suitable sockets in the heads F of the heaters, and with suit able openings for the reception of clampingbolts G, which, in conjunction with the projections e, hold the heaters in proper position relatively to the box. The inner end of the junction-box has also suitable openings 1) forthe admission of the heater-Wires R. For greater accessibility in this case the entire outer endf of the casing is removable, and the wires are let in andOut through holes 9 at the top and bottom of the box, respectively.

The riser-heaters (shown in Figs. 9 to 12) have their porcelain heads F half-round instead of entirely circular. The wires in this case run in substantially the same direction as the heaters themselves, and the junctionbox consists of a frusto-conical casing h, overlapping the end of the porcelain head F of the heater and having flanges adapted to be fastened to the riser or other backing, against which the casing k of the heater is fastened. These boxes are open entirely at -the' end adjacent to the head of the heater,

while the opposite end I is provided with openings 7a, through which the conduits C are admitted. it will be understood that the connections are made in this case before the junction-boxes are applied. It is not necessary to break off the wires R and make a separate connection thereof with the linewires. The wires R may run continuously from one of the heaters to the next;constitut ing, in fact, the line-wires, the only junction to be protected being that of the wires R with the binding-posts of the heater.

Where the heaters A and A are very close together, as shown in Figs. 11 and 12, the casings k for adjacent heaters may be united into a single cylindrical casing h, which may be simply a trough-shaped piece of sheet metal with suitable flanges j for fastening it to the backing after the connections between the adjacent heaters havebeen made.

In the construction shown in Figs. 13 to 15 the truss-plank of the car is indicated at n. A backing-plate o is usually provided to prevent overheating the truss-plank and to dellect the air outward into the car, the backingplate being faced with asbestos or the like. Porcelain heads F are fastened to the backplate 0 and carry the coils and terminal wires R in substantially the same manner as in the previous figures. The outer casing p of the heater may be applied after the connections have been made between the line-wire X and the heater-wire R and is provided with extensions (1 at the ends lying beyond the porcelain heads E and serving to inclose the junction of the wires, the extensions (1 of the casing being rovided with sockets .1" for the reception of t 10 ends of the conduits C. The entire casing p, with its extensions, is fas tened to the truss-plank by means of flanges s, Fig. 15. l
