JOHN EMORY MEEK, OF NEV YORK, N. Y., ASSIGNOR TO THE I'I. WV. JOHNS MANUFACTURING COMPANY, OF SAME PLACE.

ELECTRIC HEATER.

SPECIFICATION forming part of Letters Patent No. 567,248, dated September 8, 1896.

Application led January '7, 1396. Serial No. 574,598. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN EMOEY MEEK, a

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Electric I-Ieaters, (Case B 5) 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 relates to heaters for converting electric energy into heat for the purpose of warming apartments in general, and more especially is designed to provide a convenient form of heater to be placed under the seats of street-cars of the type in which the said seats are placed crosswise of the car. The form of electric heaters heretofore in general use has been so complicated or bulky that the question of division so as to place one under each cross-seat in a car has been one of some practicable difficulty. To avoid this and produce a heater which shall be light, compact, and capable of such arrangement, I have designed the form illustrated in the accompanying drawings, in which- Figure l is a plan view of my heater with a portion of the casing removed. Fig. 2 is a cross-section on line 2 2 of Fig. l. Fig. 3 is a cross-section on line 3 3 of Fig. l. t Fig. 4 is an enlarged detail view of a portion of my heater with parts broken away. Fig. 5 is a cross-section on line 5 5 of Fig. 4. Fig 6, is a cross-section on line G 6 of Fig. 4.

The essential feature of my invention consists of a woven fabric of asbestos or similar incombustible and insulating ber which has an electric conductor embedded in the woofthread thereof throughout certain sections, the intermediate portion of the fabric having the conductor omitted from such Woof-thread and the fabric being bent into one or more folds along these lines where the conductor has been so omitted. This forms a compact but effective heater which can be easily placed in a light sheet-iron casing.

Throughout the drawings, like referenceigures refer to like parts.

1 is the inclosing frame or case of the heater,

` which may be made of light sheet-iron or wire or some other metal construction.

2 generally is the woven fabric of asbestos fiber, which is bent into several folds 2f 2b 2. These folds are kept at proper distances one from the other and given additional insulation one from the other by the interposing strips 3, which may be of asbestos millboard or hard fiber or other insulating material.

4 4 are little knobs or projections on the frame l, and serving as means of lifting the same slightly from the floor when the heater is placed upon the same.

5 5 are the terminals of one section of the electrical conductor embedded in the woofthread of one of the folds of the heater. This wire or other electric conductor is omitted from the Woof-thread of the fabric along the lines 6 6, on which the folding of the fabric occurs, and, if desired, a portion of such fabric may be cut away along said lines of folding, as is shown in Fig. 5.

7 is a bolt, and 8 is a nut coacting therewith, to hold the various parts of the metal shell l together, as shown in Fig. 5.

9 is a layer of asbestos millboard or other insulating material placed inside of the heatershell and on which the lower part of the heater rests.

10 lO are air-spaces left between the folds of the fabric.

11 is a piece of hard fiber or other insulating substance, in which the binding-screws 12 12 for the electric connections are mounted. The fabric containing the electrical conductor is treated with any proper size or material for stiffening the same and rendering the liber waterproof before the said fabric is bent into the folds shown. The substance which I have used for this apparatus is what is known as japan The various sections, electrically supported one from the other, formed by the folds and arrangement ofthe conductors above described, may be connected together at their terminals 5 5 in series or in multiple arc, as is preferred. I prefer, however, to connect corresponding sections of the different heaters placed under the various seats of the carin series, so that the heating-current may be sent through the bottom IOO told of each heater in the ear, or through the bottom fold and the one 'next to it in eaeh heater, and. so on. ln this way an eqnable distribution of the heat, whether the saine is great or small, is p rodneed.

The method ot' operation of the invention is ot' con rse clear trom the foregoingI description. Theheaters are placed under the seats, and may be loose or fastened. The terminals of the electrical conductors are connected n p, as may be desired, and thrown into eirenit with the current vfrom the so'nrce of supply to the earinoto1n llavin` there't'ore described my invention, what I claim as new, and desire to protect by Letters Patent, is

l. An electric ear-heater which consists ot a woven fabric oi. asbestos, or similar ineembnstible and insulatingl `fiber, with an electric conductor embedded in the woot of the fabric, the said fabric. being folded upon itselt' one omission of the conductor t'roin the thread ot' the woot. along and adjacent to the line oli' each told, substantially as described.

in testimonyv whereoil I affix my signature in presence ot' two witnesses.
