FLORELLA L. KINSMAN, OF MAGOG, QUEBEC, CANADA.

CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 241,547, dated May 17, 1881.

Application filed January 31, 1881. (No model.)

To all whom it may concern Be it known that I, FLORELLAL. KrNsMAN,

of Magog, in the county of Stanstead and Province of Quebec, Canada, have invented certain new and useful Improvements in Gar-Heaters;` and I do hereby declare the following to bea 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, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to certain improvements in car-heaters, the object of which is `to allow air to befed to the tire through the sides of the fuel-receptacle as well as through the grate; to crush or break the slag, clinkers, or slate which may accumulate in the fuel-receptacle to provide for the thorough and constant feeding of air to the hre-chamber, whatever may bethe direction of the moving car; to regulate the air-supply to the tire-chamber 5 to 'feed the air-supply to the lire-chamber evenly; and to regulate the air-supply or draft to the airchamber. l

In the annexed drawings, Figure 1, Sheet l, is a side elevation of my improved car-heater with a section of a car-floor; Fig. 2 is a plan view of a section of the car-licor, showing the upper exposed portions of my car-heater. y Fig. 3 is a bottomview ot' the heater. Fig. 4, Sheet 2, is a longitudinal vertical section ofthe car- `heater on line m x otFig. 2. Fig. 5 is an end viewthereof. Fig. 6 is a transverse vertical section on line y y, Fig. 2; Fig. 7 is a detail view of the rack-barand its spring. Fig. 8 is adetail of the crank-rod of the worm-gear wheel. Fig. 9' isa detail ofthe detlector, and

Fig. 10 is a detail of the connection between the bar and shaft which operate the grate-bars.

`Corresponding parts in the several figures with iin gers d, suitably secured to and projecting from theV walls of the chamber inwardly and downwardly, to form a tapering receptacle for the fuel, to permit theair to be fed to the fuel from the sides as well as the bottom of the receptacle. The combustion-chamber D is provided with a smoke exit or pipe, d.

Resting in bearings secured to the chamber D are the grate-bars E, which form the bottom of the fuel-receptacle. The bearings of `thegrate-bars are arranged below and laterally beyond `the bottom of the fuel-receptacle, by whichY clinkers, slag, ashes, Ste., cannot jam or clog said bearin gs to interfere with the proper working ofthe grate-bars. These bars are T-shaped in cross-section and have depending arms, as shown.

Passing transversely through and connected to the depending arms of the grate-bars is a bar, c, the outer end ot' which works iu a bearin g-plate, `e secured to a bracket on thechamber C. One end of a shaft, F, has a bearing in the bracket of the plate e', and is loosely connected to the bar c by an arm. The other end passes up through the bottom andoorjof the car, and receives a removable lever, j', to enable the operator to readily turn the rod F to give an oscillating movement tothebar c, and, in turn, oscillate the grate-bars to clear the latter of accumulated ashes. The objectot' making the grate-bars T-shaped in cross-section, and to give them an oscillating movement, is to break or crush the cinders, slag, or elinkers, as well as to remove or shake `the ashes from the fuel-receptacle. The first-mentioned result is accomplished in the following manner, viz: Upon oscillating the grate-bars through the bar c and shaft F the width of the spaces between them will be increased, when the cinders or clinkers ll such increased space,`and upon the return of the bars to their normal position the flanged bars have a shear cutting or crushing action upon the cinders or clink-- ers, thus reducing them to permit their easy passa-ge between said grate-bars.

Pivoted in the bottom of the outer chamber, C, and below the grate-bars E, are the dampers G. arranged in two sets or series.` It is obvious that they may be arranged differently, if desired. Each of the dampers is pivoted to a bar, g the outer end of which has a bearing in the plate e', heretofore mentioned.

IOO

Engaging with the bar g, near its outer end, is a crank, h, of a shaft, H, which is supported in bearings secured to the chamber C. This shaft is provided with a worm-gear wheel, I, meshing with a worm, i, keyed or otherwise fastened to the shaft i', which is supported in the bracket or extension of the chamber G, passes up through the Hoor, and receives a hand-wheel, J.

Gl marks a deector attached transversely to the chamber D, and located below the gratebars E and between the two series of dam pers.

Upon revolving the handwheel the worm will communicate motion to the wormgear wheel, which, in turn, through its shaft and crank, will operate the bar g to move the dampers G By this means the operator can openl or partially open the dampers, and hold them in such position that when the car is in motion they will be presented obliquely toward the air, by which a strong current will be deflected into the combustion-chamber. It is apparent that this result can be brought about without regard to the direction in which the car is movin g; and, further, the draft can be easily regulated in volume, while the position ofthe dampers will not be liable to change through the jarring motion of the car. The deflector is to direct the air admitted through the first series of dampers into the forward part of the coinbustion-chamber to insure an even draft, and to prevent the current from being directed against the back partof the combustion-chamber, as it might be when the car is moving rapidly.

K marks a magazine, which extends from the upper iioor A down into the fuel-receptacle a suitable distance to make the heater self-feeding. The magazine is covered with a lid, k, provided with a handle, to prevent the escape of gases from the combustion-chamber into the car. As a further protection, a pair of hinged doors, Ic 7c', may he placed over the magazine and its lid, as clearly shown in Fig. l.

The outer or air chamber, G, is provided with a hinged door or damper, c, at the lower part of each end thereof, which opens upwardly. lo each door is connected a rod, Z, the upper extremity of which is connected to arack-bar,

L, passing up through the bottom and floor, and provided with a series of teeth or serrations, Z', engaging with aplate, M, which surrounds the orifice made for the insertion of said rackbar. A spring, m, (shown in Fig. 7,) presses against the rack-bar L, to keep it in engagement with the plate M.

An airspace entirely surrounds the fuel-magazine, into which opens a iue, N, running between theiloors, from which one or more smaller ilues, u, open into the car. The flues n may or may not be provided with aregulating-reg ister.

When the caris in motion the door or damper on the end of the air-chamber nearest the forward part of the caris partiallyor fully opened, as desired, when the currents of air will be directed against and around the combustion 4of the doors or dampers c.

In warm weather the air-space may bc filled with any suitable material which will allow1 free passage of air, but arrest dust, Src., by which the car may be readily and easily ventilated.

.Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
