WHEEL-FLANGE OILER.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed June 1, 1911. Serial No. 630,640.

and WALTER A. 'BAIsLnY, both citizens of the United States, residing in the city and county of San Francisco andState of California, have invented new and useful Improvements in Wheel-Flange 'Oilers, of which the followingis a specification.

This invention relates tolubricators for the flanges of car wheels, and the like.

The object of the invention is to provide a simple and practical device for applying oil, or other lubricant, directly and economically into the fillet of locomotlve wheels, etc., for the purpose of preventing wear on the flanges and rails.

The invention consistsof the parts and the combination and construction of parts,"

as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 1s a slde elevation of a part of a locomotive showing the application of the invention. Fig. 2 is a plan viewof the same. Fig. 3 is a longitudinal section through the main part of the lubricator. Fig. 4 is an end view in partial section of the same.

A is a valve casing, suitably secured in juxtaposition to the wheel to be lubricated, and represented at 2. As here shown, this valve casing is rigidly supported by a bracket 3, Fig. 2, on a suitable part of the engine frame. As shown in Fig. 3, the casing is cored out to accommodate a plug 4, which has an outwardly seating valve head 5 adapted to fit against a corresponding seat formed in the nipple 6, which screws into the casing. The valve 5 is normally pressed against its seat by means of a spring 7 surrounding the plug or stem 4.

The portion of the nipple 6 beyond the valve has an enlarged chamber to accommodate a piston or a plunger valve 8, which has a snug sliding fit within its cylindrical enlargement. The plunger or piston 8 has a guide stem 9 fitting a cavity in the adjacent reduced extension of the plug 4, and centers the plunger 8 with respect to the plug and valve 5. The plunger 8 has a valve portion 10, movable toward and from a corresponding seat 11 in nipple 6; an air vent 12 allowing a free action of the piston and plug.

A union 13 screws into the top of the nipor other fluid pressure supply pipe 14, Figs.

7 land 2, for receiving steam from the steam .chest, or other appropriate source of fluid supply. Whenever the steam pressure is on the top of the piston or plunger 8, the latter is moved down to close the seat 11, at the same time pushing :down on plug 4, compressing spring 7 and movingvalve 5 away from its seat to admit oil from ,pipe '15 into communication :chamber 16 within the casing A, and in which chamber 16 the reduced portion of rthe plug 4 is adaptedto work; pipe 15 being shownas-tapped into one side of the casing A, and there being suitable ports 17 which penetrate the valve chamber, and which ports are normally closed by the valve 5. @Pipe 15 leads to any suitable source of oil supply as the tank 18, from which the oil may flow to the casing, and thence to the wheel flange when permitted, by gravity. 19 land20 are suitable cocks in the oil supply pipe. In fact, thesame oil that is used for fuel may be used for lubricating.

The chief feature of the present invention resides in the means by which the oil admitted into the chamber 16 is delivered on to the wheel flange. One essential of the lubricant applying means is that it must be applied directly to .the flange rather than sprayed or projected thereon by a jet. Some sort of frictional means is desired, if not essential; and such means must be capable of instant and automatic adaptation to any irregularities in wear on the flange, must bear wit-h even pressure, must not be subjected to too great wear, and must be capable of ready re-placement when worn to any considerable degree, so as not to impair its effectiveness. To this end I use a brush made up of a series of wires, or fine, flexible rods 21 carried in a counter-weighted holder 22, swiveling on a reduced hub extension 28 of a coupler 24, which is screwed on, or is otherwise attached to the casing A. This coupler 24 has a central passage 25 in continuation of the chamber 16 and from this passage 25 extends outwardly one or more radial ports 26, discharging into an annular groove 27 in holder 22, from which groove 27 the lubricant may flow through a port 28, into the socket within which the brushes 21 are held by suitable means, as the clamp screw 29.

30 is a counter-weighted arm, suflicient to cause the brushes 21, which have their ends cut on a bevel, as shown at 31, to bear the oil supply with the valve with just the right pressure continually in the fillet of the wheel, and against the inner side of the wheel flange. The counterweighted holder 22 is suitably held in place on its hub 23, so as to be freely turnable thereon by any appropriate means, as the nut 32.

In practice the lubricator is suitably mounted upon the engine or other vehicle, substantially in the manner as shown in Figs. 1 and 2, so that the brush 21 will bear against the wheel flange and the device connected up to suitable sources of steam and oil supplies. In running down-grade or operating on curves, the operator simply turns a three-way valve 33 to admit steam through the pipe 14 to the'outer end of the plunger or piston 8. This results in an inward movement of the plunger and of the plug 4 until the plunger seats snug on the seat 11, thereby sealing the steam off from the oil supply. The inward movement of the plunger 8 to its seat 11 opens valve 5 and allows the oil to pass from pipe 15 through port 17, and around the valve 5 into chamber 16, thence through passage 25 and ports 26-27 and 28 into the socketed head of the brush 21; the oil thence flowing down through the numerous channels and ducts formed by and between the wires of the brush. The holder 22, being swivelly n;ounted and counter-weighted, bearsCOnstantly with just enough pressure to insure the application of the oil or other lubricating fluid, in proper manner, to the inside of the flange. By this swiveled brush the right quantity of lubricant is delivered in just the right place. Cutting off the steam supply through pipe 14, and exhausting the having ports registrable with said oil outlet, a lubricant distributing member carried by the holder, and fluid pressure means controlling the intermittent flow of oil between said inlet and'outlet.

2. In a lubricator, the combination with the part to. be lubricated, of a casing, and a counter-weightedmember swivelly mounted on the casing, a brush carried by the counterweighted member in yielding frictional contact with the part to be lubricated, and means for feeding the lubricant to the brush through said casing.

8. In a lubricator the combination of a the swivelly mounted member, and a distributer carried by the swivelly mounted member and adapted to contact with the part to be lubricated.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
