IMPROVEMENT IN OAR-HEATERS.

TO WHOM IT MAY'CONCERN? Be it known that we, A. H. LlGHTHALL and CHARLES F. N ORTH, of Oohoes, in the-county of Albany, and State of New York, have invented anew and valuable Improvement in Devices for Heating Railroad-Cars; and we do hereby declare that the following is a full, clear, and exact description of the construction and operat'ion of the same, reference being had to theannexed'drawings, making a part of this spe cificatiomand to the letters-and figures of reference marked thereon.

The object of our invention is to provide means for heating railroad-cars that shall be more cheap, simple, and efiicient than any similar device heretofore known or .used for that purpose. v

To this end we construct shooter in the form shown o'n Figure 1 of the drawings, the particular parts of which are represented by the letters hereinafter mentioned, fllld we arrange it for adjustment in the bottom of the ear. The top of our heater is raiscd abou't' thrce-cignths of an inch abovethe cnhbottom iiiside the car,

being about the height of an ordinary met, so that when matting is sprcad,the surface thereof is flush with the top of the heater. 1 I I Letter A, of the drawings, represents a bed-piece of the car. Letter Bis the outside cylinder of the heater, constructed of sheet iron. Letter 0 isthe inside cylinden-al'so constructed of sheet iron. The air-space between said cylinders is about eight inches .in width. Letter 1) is the cast-iron fire-box. The space between sai 'dfirebox and cylinderO is about eight inches, in width. We call the latter the hot-air space, and the first air-spacementioned the cold-air space.- Letter E is the register, by which hot air is admitted to the car. Letter F is a circular rim, that rests onthe cylinders B and O, and covers the cold-air space, and at the same time forms a support for the register E. Letter G is the damper rod, extending through the cold-air space from rim F to the bottom of the heater. Letter H is the damper attached to the rod G,'an d operates as shown in the draught-space Letter I represents thcdraught-funncl, through which the draughtfor the fire is detained. It may be shaped either in a circular or square form, and it isdesigned by its funnel-shape to secure additional draught from the movement of the cars. Letter J is the'lid of the fire-box, which is heldin'its place by means of the lugs'L. Letter is the escape-flue. We usually attach a pipe to said flue, extending underneath the ear, to one corner thereof, and-to its top. This device secures additional draught to the heater, while it also condfi ets elf-into the atmosphere all smoke and gas. Letter N is a rod, attached at its lower end to the grate of the fire-box, and its upper end is adjusted in the clutch 0,50 as to make it easilyremovable. Its office is to hold the grate firmly in its place, and at the sainc time to supply means for shaking said grate and therewith the fire. Letter K is an ear cast on the top of the lid of the fire-box,.designed to furnish means for releasing said lid and removing Letter Preprcsents perforations in cylinder 0, designed to allow cold air to pass from the cold-air space into the hot air, and thereby creating a current. 'Letter Q is a cast-iron plate, resting upon thc'bed ofthe car, and-to which the entire heater is attached, as shown on the drawings. Letter R is the ashbox. Letter S is a small circular piece of cast iron, fitting an opening in the bottom of the ash-box.,in the same mapner as a. griddle fits a boiler-hole in a stove, and it has a wire attached to its side, connecting it with the grate of the firebox. This wire is marked T-on the drawings. The oiliee of this griddle S is to afford means for the escape of ashes when the fire-grate is shaken or dumped. Letter U is a lever, constructed in the form shown on Figure 3. It is the instrument by which we shake the fire'gratc, operatethe dampers, and remove and replace the lid of the firebox.

Our heater is peculiarly well adapted to the use of street-oars, and it is for that especial purpose that we recommend it to the public. I i

What we claim as our invention, and desire to secure'by Letters Patent, is- A heater forrailro'ad-cars, having cylinders 13 and C, fire and ash-boxes, as described, rod N, clutch O, lugs L, (lrnughbfunnel I, griddle S, and wire T, constructed, combined, and arranged substantially as specified.
