JAMES SPEAK, OF PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 84,312, dated November 24, 1868.
IMPROVEMENT. IN RAILROAD-CAR S'IOVES.
The Schedule referred to in these Letters Patent and making part of the name- To all whom 'it may concern invented an Improvement in Railway-Gar Stoves; and
I do declarethat the following isa clear and exact description thereof, reference being had to the accompanying drawings, and letters of reference marked thereon. p
The nature'of my invention consists in the arrangement of self-acting valves, on the top plate of a railroadcar stove, in such a manner as to allow the stove-pipe to extend through the pipe which conveys cold air to the stove, and by which means the air is not only heated already when passing down around the stove-pipe, but the necessity of making a separate hole for each of the pipes is obviated, and a great saving in room-a very important item in a railroad-car--efiected.
Figure 1 is a sectional view of the stove, with the Figure 2'-is a view of the two valves, showing the weights, B B, on the under side. a
Figure 3 is a view of the top plate, with the valves A A in it partly open. v
Figure 4 is a view of the ring between the valves, with arms and hearings on which the journals of the valves work, and which is fastened to the top plate,
allpwing the stove-pipe to pass through it between the va ves.
The fire-box of the stove is surrounded by an airjacket, to the centre of the top of which the cold-air pipe is attached. The ring, fig. 4, with its journal, is attached to the top plate of the air-jacket, where it joins the cold-air pipe, and to its journals are attached the valvesAA, in such a manner that, by their weighted downward current of air getting heated from the moment it enters the vertical part of the cold-air pipe; by reason of the stove-pipe passing through the latter, till it has passed the fire-box, is distributed into the car! through openings in the lower part of the hot-airjacket \Vhen the cars stop, .the downward current of cold air ceases, the valves A A close by their weights B B, and the hot air is thus prevented from escaping.
By my improved arrangement of the valves, three great advantages over any other construction or arrangement are effected:
First, the cold air begins to be heated the moment 'i it enters the vertical part of the cold-air pipe, as it surrounds the hot stove-pipe, and thus a car is muclrquicker heated, the air passing out of the jacket into the car being much-hotter than if the stove-pipe passed out of the car alongside ofthe cold-air pipe.
Secondly, the necessity of cutting a separate hole in the roof of a car foreach of the pipes is avoided.. Oar-roofs are made very light, of necessity, to avoid. too great weight, and any openings in the same tend to weaken them. By passing both pipes, one within the other, through one hole only, I thus gain in the strength of the roof; and,
Thirdly, I effect a saving in room in the car, which, especially in passenger-cars, is of great importance, as is well understood.
I am well aware that self-acting valveshave been used in cold-air pipes in railroad-car stoves, and those I do not claim broadly; but
What I claim as new, and desire to secure by Letters Patent, is i The arrangement of the valves A A on the top plate of the stove, in such a manner as to allow the stovepipe to extend through the cold-air pipe, substantially as and for the p nposes set forth.
