RAILWAY-SWITCH HI-EATER.

To all whom it may concern: a a

Be it known that I, ISAAC C. POPPER, a citizen of the United States, residing at New York city, in the county of New York and .State of New. York, have invented certain new. and useful Improvements in Railw ay- Switch Heaters, of which the following is a specification.

My invention relates to a railway switch heater, designed more particularly for use with solidified alcohol or the likeas a fuel. :which is adapted to be placed underthe rails particularly beneath zthe switch "points andbetween theties, beingofsuch length as to extend completely across the bed ofthe track andproject a suitable distance beyond the rails on either side thereof.

i The object of my invention is to prevent "thesnow and ice from accumulatingbetween the switch points, and to melt the ice and snowtin the bed of the track between these points. l a l i 1 y r y A further object is to construct the heater 1 in sucha manner astopermitanqeasy charg ing and re-charging of theufuel from either end of the heater, regardless of the accumulationof ice and snow on the bed of the road. In the accompanying drawings Figure 11 is a plan view. of a portion of the ingthe heateruin position there- Fig. 2 is: a top plan view of the heatery Fig. .3 is a horizontalsectional view of the :heater; 1 i

Fig. 4&is a vertical Ion 't udinalsection on Fig. 5is a transverse section on line 5--5 ofFig; l Fig.6 is asplan viewuofa modified form of heater; A 1 1Fig. 7*is a side elevation thereof;

Fig. 8 isa longitudinal vertical section;

9 is a transverse section;

Fig. 10 is an 'end view.

In the preferred form of my invention, the heater consists of a metal rounded body portion 1, which acts to shed off or melt the falling snow, or the accumulation of water from the melting ice, and a flattenedbottom portion 2, the whole made preferably of one piece and suitably fastened together as at 3, see Fig. 5. The wall portions of the body portion 1 are provided with a longitudinal row of perforations 4 and placed near the heater.

roof of the heater, said perforations being protected from the water by suitable flanges ,5, extending practically the entire length of the-heater. j

The open ends of the heater are closed preferably by vertical sliding gates 6. 6, which are received within slots 7, 7, ar-- ranged in the upper half of the body por lower half 9 being of such a diameter as to conform tothe lnner contour of the body portion and flattened along the lower edge as at to rest upon the bottom of the A projection or knob 11 projects upwardly from the gate to facilitate its removal. 1 The gates are alsoprovided with perforations 12' in the upper portion .thereof which are in line with the several perforations in. the wall portion and are likewiseprotected from the weather by flanged members 13, .13, which areginreality, a continuation of the flanges 50f the wallportions. These flanges 13, 1?

[act tostrengthen the construction as a whole.

To facilitate the charging and discharging of thelieater, a sliding tray 14 is adapted to be received within the heater and rest upon the bottomathereof. This .tray is provided :with flanges bent upwardly along its sides and ends and endportions as at 15 and 16, andisprovided at intervals along its length withtransverse flanges 17, which act to di- 'vide the tray into sections to facilitate the distribution of the cans of fuel along the entire length of the heater. the tray is provided with a projection or Each end of knob 18 to render it easily removable.

- In the modifiedforhnfias shown in: Figs.

6, 7 8, 9 and 10, Thave disclosed a heater wvhich generally is rectangularin shape con.

sisting preferably of a sheet-metal top 19, a bottom 20, and perforated ides 21 and 22, the bottom and top bent inwardly at their ends to form flanges 23 and 24. Perforated doors 25 and 26 which are preferably hinged to the downwardly projecting flanges 23 of the top member 19 are adapted to form a closure for each end, beingprovided on their lower ends with suitable fastening means 27. The perforations in the sides and doors are preferably protected from the tively.

weather by'suitable'flanges 28 and 29 respec- Reeeived within the heater and on the bottom is a similar tray 30 bent upwardly at either end as'a't 81 and provided with a knob or projection 32 to render the tray easily removable when desirable. Transverse channels 33 are arranged at intervals along thetray to divide the latterinto suitableseetions, inorder that the cans of fuel' may be properly distributed to render the I greatest'eflicieney. 1 1

As disclosed, I'have provided a heater for the above purpose whieh'isvery simple in construction, very easily 1nstalled,-and one wherein the fuelmay be easily placed or replaced as desired with the; least amount oi.

' trouble, making it possible for one attendant to tend several miles of switches as comparedwith three or four men now required to takeeare of some two switches in severe weather.
