J. R, STEIGER. AUTOMATIC! LUBRIGATOR FOR SHAFT BEARINGS.
APPLICATION FILED MAY 19, 1906.
.IAKOB ROBERT STEIGER, OF NEUENKIRCHEN, AUSTRIA-HUNGARY.
AUTOMATIC LUBRICA'IOR FOR SHAFT-BEARINGS.
Specification of Letters Patent.
Patented Feb. 4, 1908.
I Application filed May 19. 1906 Serial No. 317.759.
To all whom it may concern:
Be it known that I, JAKOB ROBERT STEI- GER, engineer, a citizen of the Republic of Switzerland, residing in Neuenkirchen, Lower Austria-Hungary, have invented a new and useful Improvement in Automatic Lubricators for Shaft-Bearings, of which the following is a specification.
This invention relates to a self lubricating bearing for journals and has for its object the provision of such a bearing wherein the inbricant is contained in a reservoir formed in the lower part of the bearing and is deposited upon the journal by a ring which is supported upon the journal and projects into the lubricant and carries the same upwardly to the journal when the same is rotated. This form of bearing has been found to be defective since the rings serve to carry only a small portion of the lubricant to limited portions of the journal, rings of this character, in devices heretofore employed, being spaced some distance from each other often allowing intermediate portions of the bearing of the journal to become dry.
It is the object of this invention to provide a lubricant collector in the form of a cylinder adapted to extend practically throughout the length of that portion of the journal engaged by the bearing thereby obviating the former defective results noted in connection with separated ring collectors.
The invention will be more fully described in connectionwith the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.
In the drawing: Figure 1 is a transverse section of an improved bearing embodying the main features of my invention. Fig. 2 is a sectional view on line 22 of Fig. 1.
Like numerals of reference designate similar parts throughout the different figures of the drawing.
As shown the bearing comprises a base portion 1 provided with upwardly extending wall portions forming a reservoir adapted to receive the lubricant.
The side walls are designated by 12 and serve as a support at their upper ends or margins for a cap hereinafter described. The end walls which are designated by 13 also support the cap and their upper margins are desirably flush with the margins of the side walls 12. Desirably said end walls 13 taper from their bases to their upper margins and are recessed or slotted at 14 to permit passage of the journal or shaft 15.
A cap 10 adapted to fit upon said upwardly extending walls is secured thereto by means of bolts 9 pivoted, as shown in Fig. 1, to said walls and provided with nuts engaging the cap 10. The cap 10 is provided with a relatively thin flange 16 adapted to rest upon the upper margins of the side wallsand is pro vided with a shoulder 17 adapted to rest upon the upper margins of the end walls 13. In order to close the slotted portions 14 at points above the shaft 15 the cap 10 is desirably provided with projections 18, preferably tapering toward their lower margins and fitting inside of the end walls 13. To form a complete and effective closure the projections 18 are preferably recessed at 19 to embrace the journal or shaft 15 so that at their side portions 20 and upper portions there is provided a closure for the space formed by the recess 14.
A bearing member 3 in which the journal or shaft is seated is mounted upon standards 2 which as shown are formed integral with the base portion 1. Said bearing member 3 extends about the lower portion of the journal as shown to a point coincident with the horizontal plane through the axis of said journal. At its opposite ends the bearing member 3 is provided with extensions 21 having suitable apertures or recesses 22 adapted to receive pins 4 of the bearing cap 5 hereinafter described. A collector 8 in the form of a cylinder is mounted on the journal and overhangs the bearing and projects downwardly into the lubricant as shown in Fig. 1. As the journal rotates the collector 8 will be rotated and will carry with it portions of the lubricant and deposit the same upon the journal in an obvious manner.
The bearing member 3 is provided with a bearing cap 5 which is centrally recessed to accommodate the collector and is provided with bearing portions 6 engaging the journal said cap 5 having extensions 23 in which the pins 4v are secured and which extensions 23 are supported on extensions 21.
The centrally recessed portion 7 of the bearing member 5 spans the-collector 8 and the journal 15 between the extensions 23 and forms an intermediate space to permit the collector 8 to operate freely. The lateral margins of the cap 5 as shown in Fig. 1 are out of engagement with the bearing 3 between the extensions 23.
It will be seen from the foregoing that the journal will be thoroughly lubricated sub stantially throughout its entire length and that the structure shown provides a bearing permitting the parts to be readily removed or purposes of repair and renewal.
I claim In a self-lubricating bearing for journals the combination of a casing comprising a base portion and a cover, said base portion being adapted to receive the lubricant and having upwardly projecting side and end walls, said end walls being recessed to receive the journal'and the inner faces thereof tapering from their bases to their upper margins, saidcover having a relatively thin flange engaging the side walls of said base portion, end projections fitting inside the end walls of said base portion and closing portions of the recesses therein not occupied by the journal, said end portions being recessed to embrace I the journal, a supporting bearing for said journal comprising a lower portion mounted in the base of said casing and extending upwardly about the journal to a horizontal plane intersecting the axis thereof, a cap portion provided with pins entering said bearing at the ends thereof, said cap portion engaging the bearing and journal at its endsand spanning the journal and forming a cavity between the ends of said bearing, and an oiling cylinder extending throughout the length of said cavity and over said bearing and journal into the lubricant, the cavity of said cap portion having a radius a proximately greater than said oiling cylinc er, said ca portion being cut away laterally to permit free passage of said cylinder.
in presence of two witnesses.
JAKOB ROBERT STEIGER.
In testimony whereof I aflix my signature
