ELECTRIC HEATER.

application sied may 1o, 1an. serial No. $26,208.
To all who'ra it may conce-rn:
` State of New York, have invented cert-ain new and useful Improvements in Electric Heaters, et which the vfollowing is a specification. l
My invention relat-es to electricl heaters, particularly to such type of electric heater as is adapted for the heating of surface cars.
In heaters ofl this type ditl'iculty has been experienced in cases where the heating apparatus got out oforder, by reasonl of the fact that the entire car was therelyy disabled, or if it was used it was used withoutthe benefit of the heating apparatus.
My invention therefore has fc-Lv its object to provide'a'fheating apparatuf wherein a number of heaters are combined within each heating apparatus, and they rre so constructed that each of the heaters may be `removed and replaced by another without kao disturbing the other heaters in the casing.
- I have so constructed the said apparatus that this operation may be performed expeditiously. By this means the utility of the rolling stock of railroads is increased by reason of the fact that its usefulness is not vimpaired by delay in repairing the heating apparatus.
'A desirable form in which my invention may be embodied is illustrated in the accompanying drawings, wherein,- v
Figure 1 illustrates an elevation of a carv seat showing the manner in which :my heat ers are used; Fig. 2 is alongitudinal sect-ion of one ot the heaters on the line 2-2 of Fig. 3; Fig. '3 is a cross-section of a heater on the line 3-3 of Fig. 2;^-Fig. 4 is a longitudinal fragmentary section on the line 4 4 of Fig. 43; Fig. 5 is an external side view of an end blck; Fig. 6 is a detail perspective view of 'a supporting block em* ployed to assist Ain supporting the individual heaters. n l
MV invention in the particular form 1in whicwh it is illustrated in the accompanying drawings, employs a pair of end blocks A, each of which has slotsl a, c1 a2 which are` adapted to support the individual heaters. These heaters are designated B, and are shown as being three in number. They arel yall of they same construction, and are illus.
trated as being formed of a core b of`suitable insulating material, for which porcevlain is well adapted. This I pret'er to provide with a hollow center. b1 and perforations as at 52, and to -lnount'thereon a heating wire which. is in the form of a coil helieally wound thereon and received in peripheral grooves upon the core, the particular construction of said core however forms no part of this present invention.
The supportingl rod b"v extends through the hollow center ofeach of the heaters, and at its end passes into a perforated block C,
whereon it may be held by nuts c. The rodA is useful fory twopurposes. In the first place, to hold the heatertogether in case the porcelain core of the same is constructed of several sections, as is usually the case, and in the next place to assist in maintaining each heater in position'in the casing. The blocks C are adapted totit the grooves. a, al or a2, and when the heater B 1s secured to a pair of the said blocks and the same are seated in the said grooves, it is secured in place by suitable means. Such means as illustrated comprise a nutD having a hollow internally threaded shank d which-passes.
through a perforation a3 in the end plate and is received upon the threaded end of the supporting rod b4. may be providedy ifdesired. It will be observed that the nuts D will compensate for any unevenness in position of one -or the other of the end plates A, by reason of the fact' that, each heater may be adjusted lengthwise of the casing until it is'in aposition where it will be engaged by -each of the nuts D.
A1 lock washer d'1 q Suitable conductors Vb are connected 'to the coils 253 and pass through openings a* in the end vplates.- As many openings are provided as there 'are heaters within the I casing, so that each heater is provided with anl lir'xdependent electrical connection, and
these are separate from one another. The. rods b4 are preferably square, and the same '-is true of the 'aperture in the block C through which. the rods pass, as indicated inFig.'6 at c1. i 'I y said block, shown in dotted lines 1n sald figure, has ,a round aperture', which I shall .designate c2, and which is madel o thisr Yshape to accenunodate ltl1e 'round si? c d of nut D.
The opposite side of the.
' y 'rife angie within which the Said heatrs are contained is represented as of subers may easily be taken out from the casing without disturbing the others.A The frontplate e has the usual perforations tolpermit .the passage ofthe heated air. The casing E vinay it desired be provided with an internal lining inl the form of a sheet of asbestosel.
The' several heaters B, of which three are illustrated, may be placed in the several grooves fijalf'a. and their .electrical Vconnections b5 ateach end pass-through' the holes aL-3 inthe end plates' and are'attached to wires outside which are not illustrated. If forv any reason all of `the heaters are to be removedfromy the casing, the end blocks vA may be. slid out of the channels e2 in which they are mounted in the casing. Such channels extend around the interior of the casing at each end and are of trough shape land ladapted to receive the end blocks. The
end blocks are slightly beveled upon their interior inner sides at a5 for use in .assent bling. In case one of the said heaters should 'b,disabled, or for any reason it is desired to Iremove it. and-replace ity by another, yits wiresf may be disconnected outside of the end platesfrom the electrical supply wires jand drawnthrough the perforations at inv .tliesaid end plates, whereupon the blocks C will veasily slide out of the grooves in the end plates.
I `have inthe accompanying drawings illustrated one forni in which my invention v may be embodied, and which is l the best form nowknown to me, and-I have in the` jsitely disposed end plates adaptedl to close 5,5
vthe ends' of said casing, a plurality of electricheater's lying within said casing and mounted in said end plates so as to be independently removable, and an independent electrical connection to each heater. u 2. an electric heater, an open front casinlggjfj-a plurality of heater supports dis- 4posed withrelation to said casing so as to supportA electric heaters in l'said casing, a plurality of electric heaters lying within .said casing and mountedinf said supports antially half round shape in cross-section; lthough'this shape is not material, and as* mounted iteXtends lengthwise of the ycar` and' is arranged beneath a seat F. Theslots anal, a? arel directed toward the front of' the seat, in such position that when the front plate eV is removed, any of the heate vso as tobe independently removable, and an independent electrical connection to each Theater.
