" Application med January 5, 1920. serial No. 349,553.

TOYLZZ whom/t may concern.'

Beit known that I, THOMAS W: DEMA- Rnsr, a jcitizen of the United States, and a `:resident of Pittsburgh, inthe county ofAl- "legheny and State of Pennsylvania, have inlvented certain newqand useful Improvements in Journal-Box` Lubricators, of which the following is a specification.

My invention relates in general to lubricaters;` and more particularly to pressure lubricators, andglias special reference to the provision of an improved type of lubricator adapted for theautomatic feeding ofthe" lubricant tovdriving box journals or railway locomotives 1n order to insure the pressure of a `continuous ilmof grease between the jbearingsurfaces of the axle` and journal* bearing restinguponrit and thereby, as far "as possible,` minimize the occurrence of a j to locomotive drivinigbox journalsand that i i general typeinwhich my present invention hot-box andthe `frequent stoppages and interferences incidental thereto, and whereby not only maythe life of thejournal brass i be greatly increased but the locomotive may be kept on the road fora longer period of timewithout lay-up in the shop orreplacementoflthejournal 'brass7 thus avoiding both 1theeXpense of new material and of labor incident to placing it in position, and

` also loss of the use-of the locomotive. 30

`designed particularly for feeding" hard Lubricators of thel` type referred to are greasein cake "form, rather than iuid oils,

finds perhaps its. greatest field of utility includes 1 a perforated I or foraminous plate which bears marginally against-the journal of the drivingbox andsiis adapted to distrib- 1 bute `the grease andregulate the feed thereof to the axle; a follower-plate or riser, which supports the grease cake, and a spring actingpn the follower-plate or riser to keep the grease cakevin contact with the perforated plate,Y `all containedlwithin a` casing or cellarb Means are providedby me for pulling `down .the: follower-plate and distributer plate, whether for inspection of the condition of the lubricator or for replacey grease cake or parts worn away in Service.1

The principal i. objects of `my present invention` are` `gentn'ally lto` improve, sim lify, andycheapen the cost of producing ubricaters1 ofthea character referred to; to `ren-` ider such i lubricators less complicated in structure and more eilicientin operation, and

less expensive in manufacture and in the cost of maintenance; the provision ofthe sitionin order to permit the insertion of a fresh cake and which is below such plate whenthe latter is in its upper position in which the cake is brought into action on the feedor distributer plate; the provision of a spring` supporting device acting on the riser-plate at `a number of points. so that the plate.` is not 4only supported on the bottombut `also is guided on its sides whereby any `tendency toward cocking and consequent cramping` in the casing is avoided; vthe provision of a bottomless container-cellar having continuousV sides and ends adapted to contain the grease-cake and prevent on the lone hand any lateral exudation there- Vof with consequent loss and on the other hand the entrance of any foreign matter; `the provision of a riser-plate provided with raised longitudinal sides of sufficient depth to contain the grease-cake in such a maulner as to prevent any seepage or loss of `grease from the riser-plate except through a fresh cake of grease; the provision of a container-cellar provided with continuous ends and sides of sufficient depth, in combination with a feed-plate and riser-plate, to

contain and cover the grease-cake on all sides while the lubricator device is in operative position; together with such other objects as may hereinafter appear.

In attaining the objects referred to, togfether` with `such additional benefits and advantages asmay bevbelow pointednout,

Patented N0v.15,'1921.

embodying my present improvements ;l

Fig. 2 is a longitudinalsectional elevational view thereof taken on the line 2-2 of Fig. l;

Fig. 3 Vis a transverse sectional elevational view thereof taken on the line 3.-3 of Fig.k

1; and

p AF ig. 4 is a perspective view of a conventionalform of grease-cake, inserted in the device inthe first instance.

On referring to the drawings, it will be observed that I have indicated a'topless and bottomless cellar 10 provided with continuous ends and sides, 11 and'12., the ends 11 being marginally curved, as. 1sY perhaps most clearly to be seen `on viewing Fig. 3, to

, conform to the contour of the axle 13.

Within the cellar is arranged a foraminous grease feed or distributenplate 14, having a number of perforations 15, the plate 14 being also curved, as clearly to be seen on inspectionof Fig. 3, to conform to the contour of the axle 13.

With the cellar 10 and surrounding the feed-plate 14 is a follower-plate or riser 16 which carries the grease-cake. This riser 16 has upturned sides 17 provided with inwardly turned marginal portions 18 adapted tok contact with shoulders 19 formed on the downwardly turned sides 20aof the feedplate 14, as clearly to be seen on viewing the dotted portion of Fig. 3, in order that downward movement of the riser 16 may carryV along the distributer 14.

' `*For sustaining the riser or follower-plate 16, which carries the grease-cake 31, and for pressing it upward in order to force the grease-cake against the feed-plate 14 and thereby press the grease, as it becomes warmed, through the apertures 15 in the plate 14.V and so afford a continuous feed of grease to the axle 13, I employ a number of coiled spring devices 20, each of which is of a generally inverted U-form (see Fig` 3) Y and is vprovided at each end with a number of coils 21V which are disposed in retaining sockets 22-formed in the walls 12 of the cellar 10.

The ends 23 of the springs are inserted in openings in the sides 12 of the cellar in order to keep the springs under compression and thereby insure that the riser 16 is caused .4 to approach the feed-plate 14, as closely as the body of the interposed permit. l 1

In order to afford; full support for the follower 16 at bothen'ds thereof, the legs grease-cake will g 24 of the spring device 20 are bent laterally and may be .conveniently made integrally so as to continue the y'support of the riser or follower entirely across its endsas indicated at 25 (see Fig. 1) and afford a fourpoint support thereto, and prevent canting.

As further means for preventing any canting of the riser or follower 16, brackets A 26 26 are amlied to the under side of the riser or follower 16 and so arranged that the portions 25 of the spring device shall at all times be confined to movement within the length of such brackets.

For retracting the follower 16 from within the cellar 10, that is withdrawing it therefrom and into the position at dotted lines in Fig. 3, for replacement of the grease-cake, a number of depending legs 27 (see Fig. 2) apertured as indicated at 2S for the reception of hooks, (not shown), are conveniently employed.

Inasmuch as the retraction of the riser 16 eventually carries along with it the feedplate 14, owing to the contact of the marginal extensions 1S with the shoulders 19, above referred to, it will be perceived that the.distributer-plate 14 may be readily removed at any time for cleaning or replacement.

From inspection of Fig. 3, it will also be apparent that the construction described permits the retraction of the riser or follower 16 to a point suiiiciently far below the lower margin 29 of the cellar 10 to permit the insertion of a fresh grease-cake between the lowermost point 30 of the feedplate 14 and said riser 16, without any interference by the outer end 11 of the cellar 10.

As will be understood on viewing Fig. 3, care should be used in assembling the device in order to keep the spring coils 21 well within the sockets 22 so that such coils may not interfere with either the upward or downward movement of the riser 16.

TWhile I have shown in full lines in Fig. 4 a conventional form of grease-cake, 31, to be inserted in the device in assemblingV it in the first instance, it will be understood that the cakes of grease subsequently inserted from time to time in replenishing the supply are of rectangular cross-section as indicated in dotted lines in such Fig. 4.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is` 1. A lubricating device comprising, in combination with a casing, of a distributer, a lubricant-supporting follower or riser, and a spring device arranged in said casing outside of the path of movement of said distributer and riser, and adapted to cause said riser to approach said distributer, the body of the spring device being below the riser when the riser is in its uppermost position, and above the riser when the riser is in its lowermost position.

a spring device in said casing for causing said riser to approach said distributer, the spring device being so constructed and arranged in the casing as to permit the riser to pass it in either direction without interference with its movement.

3. A lubricating device comprising, the

combination with a casing, of a distributer,

a lubricant-supporting follower or riser and spring means acting in opposition to each other on both ends of said riser and adapted to cause it to approach said distributer.

4. A lubricating device comprising, the

combination with a casing, of a distributer,

a lubricant-supporting follower or riser, and spring means acting 1n opposition to each other on opposite portions of said riser and closed sides and ends and an open bottom distributer w all so arranged that said riser may be withdrawn throughthe open bottom of the casing for the insertion of a fresh supply of lubricant upon the top of said riser.

47. A lubricating device comprising, the combination with a casing, of a distributer, a lubricant-supporting followerfor riser, and a spring device arranged in said casing for causing said riser to approach said distributer, and means for limiting the maximum distance of separation between said riser and distributer, the said riser having upwardly7 extending longitudinally arranged sides of a height greater than the maximum distance of se aration between said riser and iiereby lateral displacement of the lubricant carried by the riser is prevented. i

8. A lubricating device comprising, the combination with a casing, of a distributer, a lubricant-supporting follower or riser, and a spring device arranged in said casing adapted to cause said riser to approach said distributer, said riser and distributer being provided with means for inter-engagement whereby7 the distributer may be retracted when the riser is retracted from said casing.

9. A lubricating device comprising, in combination, a casing, a distributer, a lubricant-supporting follower or riser, and a spring device arranged in said casing and adapted to cause said riser to approach said distributer, all so arranged that the riser may be retracted sufficiently far below the lower edge of the casing in order to permit the insertion of a fresh supply of lubricant.

10. A lubricating device comprising, in combination, a casing, a distributer, a lubricant-supporting follower or riser, a spring device arranged in said casing adapted to cause the riser to approach the distributer, said casing having continuous closed sides and ends with the top substantially closed by said distributer and the bottom substantially closed by said riser but being of sufficient depth to contain a lubricant supply cornpletely inclosed between the side and end walls of the casing and Said distributer and riser.

11. A lubricating device comprising, in

combination, a casing, a distributer, a lubricantsupporting follower or riser, and a spring device arranged in said casing and adapted to cause said riser to approach said distributer, all so arranged that the riser and distributer may be retracted sufficiently far below the lower edge of the casing in order to permit the insertion of a fresh supply of lubricant, between saidriser and distributer.

l2. A lubricating device comprising, in combination, a casing, a distributer, a lubricant-supporting follower or riser, and a spring device arranged in said casing and adapted to cause said riser to approach said distributer, all so arranged that the riser and distributer may be retracted sufficiently far below the lower edge of the casing in order to permit the insertion of a hard grease-cake between said riser and distributer.

13. A lubricating device comprising in combination with a casing of a distributer, a lubricant supporting follower or riser, and means for causing said riser to approach said distributer, said means comprising an angularly movable member having a shiftable thrust engagement with said riser.

14. A lubricating device comprising in combination a casing, a lubricator supporting follower or riser, and means for causing said riser to move in one direction comprising an angularly movable member having free sliding and thrust engagement with said riser.

In testimony whereof I have hereunto signed my na me. THOMAS W. DEMAREST.
