WILLIAM F. POYSER AND CHARLES B. BOWEN, OF FORT WAYNE, INDIANA.

JOURNAL-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 732,318, dated June 30, 1903.

I Application filed February 5, 1903 Serial No. 142,072. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM F. PoYsER and CHARLES E. B0wEN,citizens of the United States, residing at Fort WVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in J ournal-Lubricators; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the same.

This invention relates to a j ournal-bearing and lubricator.

The object of the invention is to provide a self-lubricating j ournal-bearing which is simple of construction, comparatively inexpensive of production, and efficient in use, which saves time and labor over the customary practice of filling the j ournal-box with waste, which is adjustable to conform readily to the journal, and which effectually shields the journal from dust and dirt.

With this and other objects in view the invention consists in certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described and particularly defined in the accompanying drawings.

In the accompanying drawings,- Figure 1 is a cross-section through a journal-box embodying our invention. Fig. 2 is a top plan view of the lubricator removed. Fig. 3 is a side elevation of the same. Fig. 4 is a 1on gitudinal section of the lubricator on line 4 4 of Fig. 2, and Figs. 5 and 6 are cross-sections on line 5 5 and 6 6 of Fig. 2.

Referring now more particularly 'to the drawings, the numeral 1 represents a j ournalbox carrying the upper bearing-brass 2 and provided with the chamber or cellar 3 to hold the lubricant, and 4 represents the journal. Lubricating mechanism is contained within the chamber or cellar 3 and comprises a supporting-frame formed of apair of side plates 5, flanged at their lower ends to rest firmly upon the bottom of the cellar and provided on their inner sides with upwardly-projecting stand ards or lugs 6. These logs are spaced by an interposed bar or sleeve 7, provided with pintles 8,which project through the ears and side plates and to which the latter are connected by screws 9. Between the two plates5 are arrangeddistributing-rollers 10, of which one or more may be employed, two being shown in the present instance. These rollers are mounted on opposite sides of the cross-bar 7 and are journaled in a swinging frame composed of arms 11, mounted upon the said pintles S, by which the rollers are adapted to swing in a vertical plane. Bearing against the under side of these arms are springs 12, fixed to the side pieces 6 and exerting upward pressure on said arms to hold the rollers in yielding contact with the lower periphery of the journal 4. The rollers take up the oil from the chamber 3 and when the journal is in motion revolve and convey the oil thereto in such a manner as to cause an even and steady supply to the journal and prevent waste of the oil. A guard-frame 13 forms the upper portion of the frame of the lubricating mechanism and consists of side pieces 14 and end pieces 15, suitably connected, the said side pieces being segmentally recessed at their upper edges and the end pieces 15 longitudinally and segmentally curved to bear against the lower portion of the periphery of the j ournal4, and thus form an inclosing guard which prevents access of any dust and dirt which may find its way'into the chamber 3 to the rollers or lower surfaceof thejourn al. The

guard-frame is normally held in contact with the journal by pressure-springs 16, secured to the side frame-pieces 5, each-of said springs consisting, I preferably, of a single piece of spring-wire bent into V form and havingits ends-bearing against the under sides of the side pieces 14 of the frame 13, theintermediate portion of each spring being arranged beneatha stud or pin 17 and bearing against the upper surfaces of similar studs or pins 18, fixed to the side piece 5. By this construction it will be seen that the springs normally press the guard frame upward in contact with the journal and constantly compensate for wear.

In the operation of the device the oil, which is applied to the chamber 3 in any preferred way, is taken up by the distributing-rollers being kept in motion as the journal revolves to insure the feed of a constant supply of lubricant thereto.

The construction of our improved lubricator is advantageous in that it obviates the necessity of packing the cellar or chamber 3 with waste, as is customarily done, and insures a much more even and regular supply of oil to the journal, while preventing waste by supplying an excess amount of oil to the journal, which usually feeds to the exterior of the box under the motion of the journal. The device also automatically adjusts itself to conform readily to the lower portion of the periphery of the journal and shields the same from dust and dirt.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of our invention will be readily apparent, it is thought, without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described our invention, what frame, means carried by said frame for supplying oil to the journal, a movable guard inclosing the upper portion of the frame and lower portion of the journal, and springs upon the frame for supporting said guard and for normally holding said guard in yielding contact with the journal, substantially as described.

In a journal-bearing, the combination with a journal-box provided with an oil-chamber, and a journal, of lubricating mechanism disposed within the chamber and comprising a frame, yielding arms pivoted to said frame, distributingrollers carried by said arms, springs acting on the arms to normally maintain the rollers in contact with the journal, a guard inclosing the upper portion of the frame and lower portion of the journal, and springs upon the frame for normally holding said guard in yielding contact with the jour-- nal, substantially as described.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
