H. D. FURNISS. OILING SYSTEM. APPLIOATIQN FILED MAY 14. 1913.

j UNITED STATES PATENT OFFICE.

HENRY DAWSON FURNISS, OF NEW YORK, N. Y.

OILING- SYSTEM.

To all whom it may concern Be it known that I, HENRY DAWSON FURNISS, of New York, in the county of New York, and in the State of New York, have invented a certain new and useful Improvement in Oling Systems, and do hereby decla-re that the following is a full, clear, and exact description thereof.

My invention relates particularly to systems used for oiling journals and similar parts of mechanical constructions requiring oiling. My invention is particularly app-licable, however, to the oiling of journals and journal bearings upon railway trucks and similar' constructions in which an absorbent body, such for example as cotton waste, is used to assist in applying the lubricating medium.

It is a well-known fact that many railway accidents occur because of the failure of the oiling devices to adequately lubricate the journals and journal bearings on railway trucks. This results in the production of heated axles and bearings,the eifect of which has frequently been to bring about serious accidents.

The object of my invention is to provide an oiling system which will avoid the dangers incident to imperfect oiling, which will require much less care and attention and which will maintain a proper lubrication of the parts to be oiled for longer periods of time without reiilling. My invention is of great importance in the operation of ordinary railroad trains for the reasons indicated, but it is particularly useful, however', in the operation of trains at high speeds and with few stops.

While my invention is capable of embodiment in many different forms, for the purpose of illustration I have shown only one form in the accompanying drawings, in which the figure is a vertical section of an oiling system constructed in accordance with my invention.

In the drawings I have shown a truck 1 for a railway coach, the same having journal bearings 2 supported upon an axle 3, passing through a car wheel 4; of the usual construction. The end of the axle 3 projects into an oil box 5, having an inclined hinged lid G of the usual kind. At some distance above the bottom of the oil box 5 I provide a perforated plate or wire gauze 7 to support above the same a body of absorbent 8,` such for example, as cotton waste. Extending down to Specification of Letters Patent.

Serial No. 767,527.

and preferably connected to the perforated plate, there is a pipe 9 having its sides cut out to produce lateral openings lO. The perforated plate l0 is entirely open immediately beneath the end of the pipe 9 to provide an entirely free passage for the supply of oil from the pipe 9 to the part of the oil box beneath the perforated plate. The pipe 9 is provided with a stop cock 10L to be closed when the oilingsystem is being reiilled with oil. The pipe 9, at its upper end, leads into an oil supply chamber 11, constructed preferably upon the top of the oiling box. The oil supply chamber is provided with a hinged cover 12 which makes an air tight joint with the top of the oil supply chamber through the presence of a gasket 12 of rubber, or any other suitable material. In order to hold the cover' 12 in place a hinged bolt l2", with a thumb nut 12C, is provided, extending through a slot 1Q in the edge of the cover. It is to be understood, however, that the oil supply chamber 11 may supply any number of oil boxes with oil.

In the operation of the oiling system a quantity of oil of the kind ordinarily used for oiling railway truck journals is poured into the oil supply chamber 11, the stop cock l0 having been previously closed until the filling operation is completed. The lid 12 is then secured in place and the stop cock 10n is opened. The oil will now flow downwardly through the pipe 9 until the oil reaches the level of the uppermost portion of the lateral openings 10. A level of oil will thus be established somewhat above the level of the perforated plate 7. By this means the absorbent 8 will be constantly maintained in a body of oil of even depth. At the same time there will be present a large body of oil beneath the perforated plate, and, therefore, beneath the body of absorbent which will immediately supply a large quantity of oil to the bottom of the body of absorbent material so as to maintain the lower portion of the body of waste invariably and at all times in a body of oil. In case the oil located above the perforated plate is rapidly used up, as for example, by heating of the axle and journal boxes the large body of oil below the perforated plate immediately passes through the perforated plate at a rapid rate, thereby immediately renewing the level of oil located above the perforated plate maintaining invariably the constant feed desired. It will be understood, of course, that as the body of oil located above the perforated plate passes upwardly, said body of oil is replenished by oil passing downwardly from the supply tank l1. A greater flow of oil downwardly through the pipe 9 is possible with this construction than in previous constructions,

as the end of the pipe is not in any way,

obstructed by the presence or interposition of absorbent materials, such as cotton waste. In my system the oil may flow out of the end of the supply pipe without being obstructed in any way and the actual feed of the oil to the cotton waste takes place over an exceedingly large surface through the many openings in the perforated plate.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention.

I claim:

l. In an oiling .system the combination of a body of absorbent material, a perforated support therefor, and means for maintaining a constant level of oil therein comprising an oil supply pipe adapted to supply oil below the support and having a lateral opening to maintain the level of the oil above the support.

2. In an oiling system the combination of a body of absorbent material, a perforated support therefor, and means for maintain- .above the support.,

3. In an oiling system the combination of a body of absorbent material, a perforated support therefor, and means for maintaining a constant level of oil therein comprising an oil supply pipe connected to the support and adapted to supply oil below the support.

4, In an oiling system the combination of a body of absorbent material, a perforated support therefor, and means for maintaining a constant level of oil therein comprising an oil supply pipe connected to the support and adapted to supply oil through the support.

5. In an oiling system the combination of an oil boX containing a body of absorbent, a perforated plate supporting the same, an

oil supply pipe arranged to feed oil below V l the` perforated plate and having a lateral opening above the perforated plate, an oil supply chamber connected to the pipe having an air-tight cover and a stop cock located in the pipe.

In testimony that I claim the foregoing I `l have hereunto set my hand.
