JOURNAL-BOX LUBRICATOR.

Specification of Letters Patent.

` Patented Dec. 1, 1914.

To all whom it may concern:

Be it known that I, JOHN DUTCHMAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Journal-BOX Lubricators, of which the following is a specification.

My invention relates to improvements in journal box lubricators, and among the objects of my invention is the provision of a cellar or container for the lubricants which can be inserted into the boX,-and if necessary, removed therefrom which will retain the lubricant in the most advantageous relation to the journal and prevent leaking of the oil; which will supply only the proper quantity for lubrication and insure a perfect distribution and which will ycomprise few parts to enhance the simplicity and durability of the structure, and enable its production at a low price.

It also has for its object to provide simple means when the car to which it is applied travels in either direction to elfectually feed the lubricant to the journal.

With these and other objects in view, .the invention broadly stated, lconsists of an oil container or cellar adapted to lit into the journal box, and oil conveying and distributing means arranged in the cellar for lubricating the oil.

The invention further consists of a journal lubricator embodying novel features of construction, arrangement and adaptation of parts for service substantially as shown, described and claimed.

Figure 1 represents a longitudinal sectional view of a car journal lubricator constructed according to my invention. Fig. 2 represents an enlarged vertical transverse sectional view, taken on line .Q -2, Fig. 1. Fig. 3 represents a perspective view of the novel mechanism for conveying the oil from the cellar or container to the journal, this view being on an enlarged scale for clearness of disclosure. Fig. 4 represents a longitudinal section through one of the oiling rollers, and Fig. 5 is a sectional perspective view through oneend of the container.

Referring now to the drawings in detail, similar numerals of reference refer to similar parts in the several figures.

The reference numeral 6 represents a portion of the frame of a car or locomotive, 7 a portion of a wheel, 8 the aXle to which the wheel is secured, and 9 the brass of usual construction bearing upon the journal of said aXle, all of which parts are of any preferred construction.

I have designated the journal box by the nluneral l0 and this has the usual door opening 11 closed by the door l2, that portion of the front wall 13 of ,said box directly beneath the door I preferably make removable to permit the ready insertion into and removal of my improved oil container or cellar 14 from the journal boX. This oil container or cellar is of box-like or rectangular shape having straight or flat bottom 15, sidesl 16 and ends 17, but having its upper wall 18 made concavo-conveX in cross-section with a central longitudinal opening 19 therein, and in this top wall at eachside of said central opening is a series of oil apertures 20. The concaved upper surface of the upper or top wall receives a portion of the journal and at each end of the container or cellar an upwardly opening pocket 21 is provided, in which t the plates 22 which have their upper edges curved to conform to the circumference of the journal and are springpressed upwardly against the journal by springs 23 coniined between the lower edges of said plates and the bottoms of said pockets. `These plates 22 serve to confine In orderthat the container may be supplied with lubricant while positioned within the bearing boX, a feed pipe 24 is secured in the outer end wall of the container or cellar and at the point where this pipe enters,

The outer end Wall of the container or cellar is removably secured in place to perinit of readily placing into said container or cellar the lubricant feed mechanism 2T and its supporting frame 2S. Said frame comprises a base member 29 formed of longitudinal and cross bars, or otherwise, and from this base member rise posts 30, preferably four in number, around which are placed coil springs 3l that carry tvvo endv supporting members 32 arranged transversely and provided with openings 33, for a purpose to presently appear. The supporting frame 28 fits snugly Within the container and cannot move laterally owing to the ends of the cross bars of the base meinber bearing against opposite side Walls of said container.

Secured in the openings 33 of the j ournal supporting members 32 are the spindles 3l of oiling rollers l have provided two pairs of these rollers, ivliich are parallehtlie rollers of each pair being independently rotatable on a singlespiiidle. llhese rollers are cored out, as at 3G, and each has a circumferential groove 37 in which travel oil con ducting chains 38 which are endless and depend into the oil contained in the cellar. rlllie circumferential grooves 37 of one pair of rollers are near the rear end of said rollers and those of the other pair are near the front end thereof. Each roller has a series of spiral oil conveyingchannels 39 Which .extend from the circumferential .Groove to the opposite end of the roller. rfliese channels trend in the same direction and each has openings hl0 therein leading to the hollovv interior of the roller.

ln operation, the oil Within the cellar is conveyed upward by the oil conducting chains 3i and delivered to the oiling rollers, the oil being conveyed from the circumferential grooves 37 into the channels 3f), which in turn, during the revolution of the rollers, carry the oil onto the surface of the latter, and as these rollers project through the central opening in the top Wall of the cellar and are held elevated by the springs 3l they rotate in contact with the journal; in fact, are rotated by the journal; the oil beingtransferred, at least in part7 to the journal and assuring a perfect lubrication thereof.

lt Tvvill be noted that the oiling rollers will revolve in the same direction and according to the direction of travel of the train, and wing to the circumferential grooves 37 of one pair of rollers being near the rear ends of the rollers and those of the other pair being near the front end, the oil is conducted into the spiral grooves of yone pair when the train moves in one direction and into the spiral grooves of the other pair When the train travels in the opposite direction. The journal is therefore properly lubricated regardless of the direction in which the train may be traveling. By the use of the spiral grooves leading from the circumferential grooves in the rollers, the surfaces of the oiling rollers are oiled throughout at every point between the circumferential grooves and the ends of the rollers at which the spiral grooves terminate. The oil is also conveyed onto the surface between the circumferential grooves of each roller and the adjacent end by reason of the side Walls of the circumferential groove being rounded, as clearly shown. 'In this manner the oil is distributed evenly along the journal, and all surplus oil drips into the cellar through the central opening 19 and the small openings 2O in the top Wall thereof. By reason of the oiling rollers being hollow, the surplus oil enters the hollow interior through the small openings l0 therein and in part drips into the cellar While part finds its Way to the surfaces of the rollers to be delivered to the journal.

Having thus described my invention, What l claim is,-

l. ln a journal-box lubricator, the combination with a journal and a j ournal-boX, of an oil cellar or container in said j ournal-box,
