Application filed July 28, 1910. Serial No. 574,225. I

To alluvho'm it may concern."

.Be-it known. that I, Gnome H. Dawson, a citizenof the United States, residing at Fort -Madison, in the county of Leeand State of Iowa, have invented a new and useful Flange-Lubricating Device, of which the following is a specification.

My invention relates to an improvement in the class of' dev1ces used on locomotives and cars for lubricating the flanges of the 4;.

' wheels to decrease their friction upon the inner sides of the rail-heads against which they ride and accordingly diminish the wear on the flanges and the rails.

In the accompanying drawing, Figure 1 shows my im roved device in elevation operatively app ied to-a wheel-flange; Fig. 2 is a section taken on line AA, Fig. 1, and enlarged, or on line A-A, Fig. 3; and Fig. 3 is an enlarged longitudinal section on line A cyl'ndric'al casing 4, formed preferably ofmetal, open atboth ends, with an internal shoulder 5 near its forward end, which is shown tapering, is adapted to be fixedly secured in operative position, as through the medium of parallel Wings 6 extending from it. Fitting within the case to reciprocate longitudinally therein, is a tube 7, shown of massive construction, having a reduced forward-end portion 8 forming a shoulder 9 to normally engage, asa stop, with the shoulder 5, and containing, by preference, near its outer extremity, a packing-ring 10; and the rear end of the sleeve is also reduced in diameter, as shown at 11, to.present a' shoulder 12, against which a relatively strong spiral spring 13 is confined, as by a plug 14 screwing into the rear 'end of the casing, This plug has a stud, 15 extending from it cent-rally into the casing, with a tapering tip 16 projecting from it and shown as entering the stud, though it may be an integral part thereof,v About this stud is confined at its rear end-a relatively light spiral spring '17- terminating at its forward end in a seating-head 18 for a pencil 19 of graphite, or other suitable lubricating material, which is reciprocatingly confined in the tube 7 against the spring-head.

While the lubricating medium is described as a pencil, it may be a pencil of tubular form, for containing the lubricant, as the 'core, in liquid or other condition.

The device maybe operatively applied to a wheel'20, as that of a locomotive, by sebent to extend horizontally, as represented or" at'a suitable angle to the flange of the wheel, inserted between the wings 6 and bolted thereto. With the device in.posi-- tion, the end of the pencil 19 bearsagainstthe outer face of the wheel-flange to lubrie cate it; and as the pencil wears away-the.

expansion of the spring 17 protrudes it to maintain its contact with the flange. More or less slight swerving of the .wheel on'its track is compensated for by the yield of the spring 17', which will permit such swerv ing to force the pencil inwardly until its advance-end is flush with that of the tube 7,

when it will still perform its'lubricating.

function; To prevent excessive s'werving of the wheel, as in rounding a curve, from encountering a rigid part of the device, which would tend to break it, the spring-pressed tube 7 is provided to yield under the'strain' and thus prevent such injury.

The washer 10 serves as a guard against dust andlother foreign matter entering the device and impairing its action.

What I claim as new and desire to secure by Letters Patent is- 1. In a flange-lubricating device, the combination of a spring-pressed reciprocating tube, and a springpressed head confined .to reciprocate in the tube and having a seat for a lubricating pencil to maintain the advance end thereof in contact with the flange of a locomotive or car wheel adjacent to whicl said device is supported.

2. In aflange-lubricating device, the combination of a case adapted to be supported. relative to the flange of a wheel on a-loco motive or car, a spring-pressed tube rec procaloly confined in the case, and a springpressed lubricating-pencil reciprocably con-- fined in the tube, for the purpose set forth. In a flangelubricating device, the comhinationof a case adapted to be supported relative to the flange of a wheel on a. 1000- motive or car, a tube in the case, a relatively strong spring in the case, against which the tube is confined to render it longitudinally reciprocating, a head in the tube foaming a lubricating-pencil seat. and a-relatively weal:

spring confined. in the case and carrying said head. for the purpose set forth.

4;. In a flangelubrieating device. the comhination of a case open at its ends and adapteuring 'a bracket 21, in suitable'position on the'truck-frame', indicated at 22 in Fig. 1, y and having the end-portion of the bracket,

A flange-lu ricating device comprising,

in combination, a tubular case open. at its forward end wherein it is provided with an I annular shoulder, a tube havin eally-redu ed endportions con ed in the diametrirelatively-weak spring confined about said stud in the case,'and ahead on the forward end of the weaker spring forming a lubrieating-pencil seat, for the purpose set forth.
