JOURNAL-LUBRICATING DEVICE.

Application led March 6, 1916.

To all whom t may concern.'

Be it known that I, WALTER H. Lav-V PHEAR, a citizen of the United States, residing at Vorcestenin the county of )Worcester and State of Massachusetts, have invented a new and useful Journal-Lubricating Device, ofrwhich the following is a specification.

This invention relates to a lubricating device particularly designed for lubricating the journals of locomotives and railway cars.

It is the general object of my invention to improve the design and construction of such lubricating devices, thereby securing increased reliability and efficiency in operation.

With this general object in view, one feature of my invention relates to the provision of a distributing roll engaging the journal throughout substantially its entire bearing length, in combination with narrow-faced feed disks engaging said distributing roll near its middle portion. Experiment has shown that the oil conveyed to the distributing roll by such narrow disks near its middle portion will spread uniformly throughout the length of the distributing' roll, thus assuring complete lubrication of the journal. At the same time the total amount of oil delivered to the journal may bc conveniently controlled. For the purpose of such control I provide sets of gage bars mounted upon slidable frames resting upon the bottom of the journal box, said bars being adjustable to control the-amount of oil taken up by the disks for transfer to the. dis-l tributing roll.

Further features of my invention relate to certain arrangements and combinations of parts which ,will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings in which- Figure 1 is a vertical longitudinal section of my improved lubricating device, taken along the line 1 1 in Fig. 3; Fig. 2 is a vertical transverse section taken along the line 2 2 in Fig. 1; Fig. 3 is a horizontal view partly inl section taken along the line 3 3 in Fig. 1,l the distributing roll being omitted; Fig. 4 is a detail sectional viewv of one of the bearings for the distributing roll, taken along the line 4 4 in Fig. 3; Fig. 5y

and its gage bars, the parts being separated, and Fig. 6 is a vertical sectional view of the sliding frame and associated parts taken along the line 6 6 in Fig. 3.

Referring to the drawings, a journal 10 (Fig. 1) of any usual form is shown extending into a journal box 11 supported beneath the. journal but not engaging the same. The journal box is supported in the usual way from part-s (not shown) attached to the bearing block which carries the load upon the journal. The journal box is composed of a base 12, end walls 13 and 14, an intermediate wall or partition 15, and side Walls 16 and 17 (Fig. 2).

A distributing roll 2O extends longitudinally of the box and engages the journal throughout substantially the full length of At each end the distributing roll 20 is provided with a shoulder 21 (Fig. 4,) and a bearing portion 22, said latter portion being received within a bearing box 23. Each box 23 is mounted to slide vertically in a guideway 24 (Fig. 3) and is forced yieldingly upwardly by a coiled spring 25 (Fig. 4). An oilingv ring 26 supported upon the shoulder 21 is effective to convey the necessary oil to the bearing 22. rihe distributing roll 20 is thus accurately positioned within the journal boX 11 and is forced yieldingly upwardly into engagement with the` journal 10.

Oil is conveyed from the bottom of the journal box to thel distributing roll by two pairs of spaced narrowfeed disks. 30 (Fig 3) each pair of disksbeing mounted upon a shaft 31 provided at each end with shoulders` 32 and bearing portions 33 mounted in sliding bearing boxesl 34. kThe boxes 34 arek supported upon ledges 35 (Fig. 1) preferably formed integral'with the end wall 134 and the intermediate .partition 15. After the parts are assembled the boxes are retained in proper position by guide strips 36 suitably fastened to the walls 13 and 15. The boxes 34 are thus mounted to slide laterally in the journal box but are held against displacement vertically. Coiled springs 37 engage the boxes 34 at one end, the opposite ends of the springs being positioned in reoesses or guides 38 formed in or securedv to.

the walls of the journal box.v As will be seen in Fig. 3. the springs 37 act to force the disks 30 yieldingly toward the longitudinal center of the journal box, such movenientA being limitedr by the engagement of the disks 30 with the distributing roll 20,

as shown in F ig. 2. @il rings 39 mounted upon the shoulders 32 provide for the suitable lubrication of the bearings of the shafts 31. The disks 30 are of such diameter that their lower portions just clear the bottom of the journal box. They are thus effective to take up any oil contained in the box and convey the same to the distributing roll by which the oil is transferred to the journal 10.

In order to control the amount of oil taken up by the disks 30, i provide gage bars 40 (Figs. 3 and 5) adjustably secured by screws 4l to sliding frames 42, two of the gage bars 40 being mounted upon each frame 42. T he frames 42 are recessed upon the under side to permit free circulation of oil beneath and around them and are provided with upwardly extending lugs 43 adapted to engage the shafts 31 upon opposite sides thereof and thus retain the disks and gage bars in operative relation while permitting free lateral movement of the parts. rlhe frames 42 are provided with openings 44 adapted to closely engage the sides of the disks and thus substantially prevent the transfer of oil except on the face of the disks. The gage bars 40 are also provided with notches 45 for a similar purpose. The supply of oil taken up by each pair of disks can thus be accurately controlled by adjusting the gage bars toward or awayr from the edges of the disks 30 and .by the provision of a pair of bars for each set of disks the device will operate equally well with the disks revolving in either direction. Additional slots 46 (Fig. 5) in the gage bars 40 cooperate with pins 47 to guide the bars during adjustment thereof.

Having thus described the construction of my improved lubricating device the operation thereof will be clear to those skilled in the art. The springs 37 force the disks 30 yieldingly into engagement with the distributing roll 2O and the pressure of the disks together with the upward pressure of the springs 25 forces the distributing roll `yieldingly into engagement with the under side of the journal 10. As the journal wears, thus reducing the size of the bearing portion, the distributing roll will move upwardly and will-thus remain in operative engagement with the journal.

By the use of the narrow feed disks positioned near the center of the distributing roll I am able to secure a substantially uniform distribution of oil throughout the length of the journal. rlhe separation of the disks longitudinally provides a sufficient width of bearing to maintain the shafts 31 parallel to the distributing roll and thus permits them to slide freely laterally in the journal box.

The construction is simple and efficient and the parts'are so designed that there is practically nothing which can get out of order or cause trouble while in operation. It will be understood that reliability during continuous operation is one of the most important features of a ournal lubricating dev1ce.

Having thus described my invention it will be evident Vthat changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims and I do not wish to be otherwise limited to the details herein disclosed.

What I claim is l. A journal lubricating device comprising a ournal box, a distributing roll mounted for vertical movement therein and engaging said journal throughout substantially the entire length of its bearing surface, narrow separated feed disks engaging said roll near its center only, supports for said feed disks, and means to force said feed disks toward the center of said box to engage said distributing roll and to force said roll upwardly against the journal.
