J. P. HARNEY LOCOMOTIVE Filed March 1922 Patented Mar. 11, 1924.

JOSEPH P. HABNEY, 0F ALTOONA, PENNSYLVANIA.

LOCOMOTIVE.

Application filed March 8, 1922. Serial No. 542,094.

To all whom it may concern:

Be it known that I, JOSEPH P. HARNEY, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Locomotives, of which the following is a specification, reference being had to tne accompanying drawings.

This invention relates to certain improvements in locomotives and it is an object of the invention to provide a locomotive with novel and improved means whereby the tractive contact of the drive wheels with the rails of the trackway may be maintained with a maximum of efficiency.

.inother object of the invention is to provide a locomotive with novel and improved means whereby the rails of a trackway may have delivered thereon air heated at such temperature to assure an effective tractive contact of the drive wheel or wheels with said rails.

An additional object or the invention is to provide a locomotive with novel and improved means for drying the rails of a trackway embodying a pipe line discharging upon each of the rails of the trackway and leading from a source of air supply arranged within the smoke box of the locomotive and at such a location whereby the air is effectively heated by the products oi combustion.

It is also an object of the invention to provide a locomotive with novel and improved means whereby heated air may be discharged upon the rails of the trackway, together with means whereby the sand, when desired, may also'be discharged with the air.

The invention consists in the details or construction and in the combination and arrangement of the several parts of my improved locomotive whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

'The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to de scribe the same with reference to the accompanying drawings, wherein:

Figure l is a fragmentary view in side elevation, with portions broken away, illustrating a locomotive provided with an attachment constructed in accordance with an embodimentor my invention, said figure being of a diagran'nnatic character;

Figure 2 is a diagrammatic view in top plan illustrating the means whereby the transversely spaced valves for controlling the flow or delivery of the sand may be operated in unison;

Figure 3 is a diagrammatic view partly in section and partly in top plan illustrating the means whereby the discharge of the heated air upon the rails of a trackway are under simultaneous control;

Figure l is an enlarged fragmentary view of the discharge end of one of the air lines; and

Figure 5 is a longitudinal sectional view taken through one of the valves illustrated in Figure 2.

as disclosed in the accompanying drawings, S denotes the smoke box of a locomolive in which is suitably positioned a tank or reservoir T adapted to contain a supply oi air under pressure, said air being delivered within the tank or reservoir T through the induction pipe 1 leading from the air pump or compressor of the type generally carried by locomotives for use in connection with the air brake system.

it each side of the locomotive is a pipe line 2 disposed in a direction and of a length to terminate at a point in relatively close proximity to a rail of a trackway and to a wheel, such as a drive wheel, of the locomotive. The lower or discharge end of the pipe line 2 is engaged within an end portion of a nozzle 3, the lower or eduction end of the nozzle 3 being defined by an upstanding annular flange 4, referably arcuate in cross section. This tango 4 provides a trap to collect moisture which may form upon the line 2 or nozzle 3 and otherwise drop down upon a rail.

Interposed in the pipe lines 2 are the valves 5 of a rotary type and, as is particularly illustrated in Figure 3, said valves 5 are connected by the interposed rod 6 for unitary rotation, so that both of the valves 5 may be simultaneously moved into open position or into closed position as desired. One of the valves 5 is provided with an operating member 7 which, as herein disclosed, is connected through the instrumentality of a link 8 with a lower end portion of a swinging bar or "rod 9, said bar or rod 9 being pivotally supported intermediate its length. Operatively engaged, l0, wtih the upper portion of the bar or red 9 18 a rod 11 which preferably leads within the cab of the locomotive so that the engineer may adjust the valves 5 into open and closed position as required.

When the valves 5 are in open position, heated air will pass downwardly through each of the pipe lines 2 and its associated nozzle 3 and be delivered upon a rail of the traclrway at a point in relatively close proximity to a wheel of the locomotive. This heated air operates to effectively dry the rail in advance oi"? the wheel and also the approaching portion of the rim oi? the wheel so that the desired tractive contact between the wheel and rail is assured. The use oi this heated air is oi particular advantage in starting or stopping.

D denotes a sand doine ot a type now generally in use and leading from sc l and overlying each side of the lOUOl'l'iul' 'a pipe 12 having itslewer end i l; UlOru Extending upwardly within the pipe through its lower closed end is a second pipe 15 of a major diameter less than the mean diameter of the pipe 12, said pipe 15 being in communication with a pipe line 2. Interposed within the pipe 15 a slide valve 16 to provide means whereby the flow through the pipe 15 may be r adily and effectively controlled as the requirements of practice may necessitate. liy having pipe 15 extend within the pipe 12: at a point above the lower closed end llof the pi pr 12, it is assured that the sand which may pass through the pipe 15 into a pipe li'ie 2 will be dry as any moisture which may within the sand held within the pipe 12 will be collected'within the lower portion oi the pipe 12 below the upper or induction end of the pipe 15.

The valves 16, which are arranged at the opposite sides of the locomotive, a e provided with the outstanding ste s l? operatively engaged with the or 'cs or a lever 18, said lever being so, if id, as at 19, substantially midway its 1 gth for swinging movement about :1 vs 1 axis.

Operatively engaged with or" the lever 18 1s a vertica eratlng bar 20. The bar 20 is pported t. 7 as at 21, at a point midw y its ends for swinging movement. Opei en 'aged with the upper end porti e 20 a rod 22 which is prei U cl :1 length to extend withinthe cal) a locomotive so that the engineer inay ei ltaueous oiening or closing of the i 16 when required. Inv operation, is to he understood that while the valves 16 move simultaincome sand pipe or nozzle but in my iinprovcd erra geinent this d culty is overcome as J the heated air in addition to acting frectly he sand also he ts the pipe and nozzle ed clileiency is obtained.

c o ning description it is to he ohv tl at a locomotive conin ERCCUM ruse with "i invention is use by reason may be assembled and opc ited, and it will also be obvious that my inv tron is susceptible oi some change and P inouiiication w thout departing from the principles and s i it thereof and for this reason I do not sn to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

it claim:

1. In combination with the smoke hon oi, a locomotive and a supporting wheel for the locomotive, means within the smoke for heating air under pressure, and means for lischarging said heated air upon as surface over which the wheel traverses.

2. In combination with the smoke box of a locomotive and a supporting wheel for the locomotive, means within the smoke box for heating air under pressure, and means for discharging said heated air upon the surface over which the wheel traverses and at a point in advance or" and in close proximity to the Wheel.

3. In combination with a supporting wheel for a vehicle, means for discharging heated air in advance of such wheel to dry the surface upon which such wheel traverses, and means for discharging sand with said air, said last named ineans operating independently of the first named means.

i. In combination with a smoke box of a. locomotive, a supporting wheel for the locoinetive, means within the smoke box for heating air under pressure, and means for discl arging said air upon the portions of the wheel approaching the surface over which the wheel traverses.

In testimony whereof I hereunto afiix my signature.

JOSEPH P. HARNEY.
