CAR-H EATER.

SPECIFICATION forming part of Letters Patent No. 401,794, dated April 23, 1889.

Application filed November l.b I 1888. Serial No. 291,015. (No mOdel-l To all whom t may concern:

Be it known that I, HENRY SCHREINER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car-IIeaters; and I do 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a car-heater; and it consists in the construction and arrangement of parts hereinafter described and claimed.

The accompanying drawings illustrate the present invention.

'Figure 1 is a vertical section of my improved car-heater. Fig. 2 is a plan view of the oil-burner. Fig. 3 is a vertical section of the burner and the circular weight suspended therefrom. Fig. 4 is an enlarged detail view of the automatic valve-controlling device. Fig. 5 is an edge view of the weighted wheel and dog.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

A is the body of the stove, and A is the burner, by which term I designate the following features viz., the circular igniting-trough B and the burner-pipe D', together with certain attachments and peculiarities of construction, which will hereinafter be described.

In the bottoni of the igniting-troughIplace a thin layer, N, of some non-combustible material, preferably sand or ashes, to serve as a medium for a little igniting-oil deposited in the trough for this purpose in starting the fire, for the reason that cold kerosene-oil (which I employ) will not ignite without the aid of a wick.

D is the oilsupply pipe, which is vcoiled upon the trough B, as shown,and is provided with perforations in the coiled portion, which constitutes the burner-pipe D. The burnerpipe D is supported upon bridges J T in the To enable the burn er to keep an equilibrium,

I provide a circular weight, U, which is suspended from the cross-pieces I I or from the trough B by chains it', and surrounds the standard C.

To provide the draft and deliver the air to the burner-pipe in a proper condition to give a steady and efficient flame, I provide segmental foraminous plates S, which cover the inclosed space of the heater and rest upon the trough under the burner-pipe. These foraininous plates greatly aid in the efficiency of the heater. I prefer to make the outer Wall of the trough higher, as shown at b, than the inner wall, as shown at b', so that the foraminous plates will rest against the outer wall and will serve to divide all the air-currents which reach the burner-pipe.

I provide an automatic cutoff foruse 1n case of accidents to stop the flow of oil to the burner-pipe, which consists of aneedle-valve, H, which is provided with a weighted wheel, II', on its stem, the weighted wheel also having a section of its circumference formed with ratchet-s, as shown at I'I. A horizontally-arranged. gravity-dog, K, is located over the wheel, havin g teeth under its outer end which engage the ratchetsteeth on the circumference of the wheel. The dog is hinged to the fixed part and may be raised by hand to release the wheel; but to give an automatic action to the parts, as required, I provide a wedge, L, which is mounted upon wheels or rollers l, which are sunk well into the body of the wedge, so as to bring the point of the wedge near the surface on which the rollers frest and cause it to raise the dog when the wedge is pushed forward. The wedge is mounted upon an inclined way, l', and when any dangerous jar or concussion arises it will shoot under the dog in the notch it" and raise the dog out of contact with the ratchets on the wheel, when the Weight of the Wheel will immediately drop to the lowest point and close the valve H. This automatic trip mechanism is placed as far down in the supply-pipe as it is possible to place it, so that a short length of pipe and a small amount of oil may lie between it and the heater, so that when the trip mechanism is automatically or arbitrarily moved to close the needle-valve the fire will go out. For this purpose the supply-pipe leads directly into the stove and is bent to form the burnerpipe, and the needle-valve and trip mechanism is located immediatelyon the outside of the stove, as shown in Fig. l.

If the trip mechanism should be moved by a concussion or jar which does not result in disaster, the parts can quickly be restored by the brakeinan or other authorized attendant and the fire relighted instantly.

E is the oil reservoir or tank, which is held in a suitable box or frame, as shown, and has a conical bottom which terminates in a coupling, P, by which the supply-pipe is connected to it, and a cock, G, is provided at this point to shut of the iiow of oil when it is desired.

Vhen it is desired to start the fire, a few drops of oil are allowed to trickle over the burner-pipe D and drop over into the sand or ashes, Where it can be lighted with a match, and the blaze from it will heat the burnerpipe to a sufficient degree to render the oil in it ignitible directly from the orifices, when the flame will start from them, and, being duly fed through the supply-pipe and needle valve and regulated and steadied by the foraminous plates, Will continue bright and effective until shut off arbitrarily or accidentally, as before described.

I may employ a spring in lieu of the weight upon the wheel, and have a dog or lever and Wedge for holding' and tripping it.

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

l. In a car-heater, the combination of standard C ,a circular burner pivoted thereon, and

and suspended from said burner, substan- I tially as described.

2. A burner for burning oil, consisting ofa suitable support, a trough pivoted upon said support and having a high outer side, h, and a lower inner side, b', a series of segmental foraminous plates, S, laid over the trough upon its lower side, and a burner-pipe, D', placed over the foraminous plates inside the higher outer Wall of the burner, as set forth.

3. The combination of a circular trough having a layer of ashes or sand, bridges or partitions a suitable intervals, apivot on which the trough is supported, and a circular burnerpipe supported on the bridges in the trough, as set forth.

4. The combination of a circular burner having a trough, as described, a burner-pipe supported upon said trough, a supply-pipe connected to the burner-pipe, and a pivot or support on which the whole is pivoted, as set forth. f

5. The combination, with a suitable support, of a circular burner pivoted thereupon and a circular Weight suspended from the burner, as set forth.

6. The combinatiomwith a heater and supply-pipe, of a needle-valve in said supplypipe, a Weighted wheel on the stem of the needle-valve, having ratchet-teeth on its rim, a gravity-dog engaging said teeth, and awedge for automatically raising' said dog, as set forth.

7. The combination, with the feed-pipe of an oil-heater, of a needle-valve, a Weighted wheel on the stem of said valve, having ratchet-teeth over a portion of its circumference, a hinged gravity-dog having' teeth for engagement with the ratchet-teeth, and a Wedge mounted on rollers for operating the dog, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY SCHREINER.
