LUBRICATING DEVICE.

SPECIFICATION forming part of LettersPatent No. 517,748, dated April 3, 1894.

Application fuea Appli 14, 1390.

To @ZZ whom it may concern.-

B'eit known that I, HENRY P. l-IUMPHREY,

a citizen of the United States, residing at Nashua, in the county of Hillsborough and l State of New Hampshire, have invented a certain new and useful Improvement in Mechanical Oilers orLubricating Devices for Journal- Boxes for Shatting, of which the following is a specification.

My invention relates tol mechanical oilers or lubricating devices lfor journal-boxes for shafting and consists in the devices and comblnations hereinafter described and claimed.

In the accompanying drawings, Figure lis a front elevation of a shaft-hanger and a central, vertical, longitudinal section of a journalbox adapted to be used with my improved mechanical oiler supported in said'hanger; Fig. 2, a side elevation of such a hanger and a vertical, central, transverse section of saidl journal-box, the lower part of the hanger and the part of the same immediately above the Journal-box being also in section in the same plane; Fig. 3, an enlarged vertical longitudiz 5 nal section of said journal-box showing the reservoir which receives the mechanical oiler and the 'oil-holes throughA which oil is introduced by said oilerI into said j ournal-box Fig.` 4, a plan of said journal-box and my improved lubricating devices, a piece of shatting and a cam thereon to operate said devices, a part of the upper half of the outer shell of said journal-box being broken away, to show the internal construction land the cover of the reservoir being open forpthe same purpose; Fig; 5, a vertical transverse section on the line 5 f5 in Fig. 4, showing the mechanical oiler in side elevation, a part offthe barrel or cylinder of the pump being broken out to show the piston-rod and the spring, Fig. 6, an isometric perspective view of the lever which operates the pump, detached.

The hanger A is of the kusual construction andmay represent any hanger or floor-bracket adapted to hold a journal-berlina horizontal position.

The journal-box B is not herein claimed being described and claimed in United States Letters Patent, No. 499,429, granted June 13, 50 1893, upon a division of .this application, but

Serial No. 347,760. (No model.)

consists of an inner shell or journal-box, proper B', formed in halves b b and lined with any anti-friction material, said halves lapping past each other, as shown at b2, to prevent a lateral movement ot' one half upon the other. 55 The outer shell B2 is also formed in halves,one

of which laps past the other at b2, saidshell B2 lsurrounding the box B and the. ends of said shell extending beyond the ends of said box. The outer shell B2 has annular ribs b4 on its in- 6o ner surface between which are arranged external annular ribs b5 on the journal-box B to prevent a longitudinal movement of the j ournal-box proper in said outer shell, said ribs b5 on the box having lateral extensions tv-which 6 5 t notches in the ribs b4 to prevent the journalbox proper turning in the shell. A projection 197 on the lower half of the shell enters a notch in the upper halt` ofthe same and prevents said halves from moving endwise on 7o each other. The shell has ears b8 whichrest yupon the fork a of theV hanger in the usual manner, being held thereon by the set-screw d and check-nut, the point a4 of thescrew 'entering a depression b9 in a cap b1@ which v7 5 rests on said shell, as described in said other application. The lower half of the shell B2 is provided with a reservoir cast or formed in one piece therewith and extending downwardly and laterally therefrom to receive a 8o pump D, as shown in Figs. 4and 5, the cylinder d of said pump being provided with annular flanges or enlargements d d2, at or near its ends, said flanges resting against the rear wall of said reservoir, against which they are held by a hook d3, adapted to ,reach partly around said cylinder d, and a bolt d4, extending through said wall into the shank of said hook, the head d5 of said bolt resting against the outside of said wall. This means of se- 9o curing the. pump in the reservoir allows it to be adjusted in height without opening the reservoir, as by loosening the bolt d4'in the hook, the pump may be raised byvraising its spout d6 and in a similar manner may be low- 95 ered and held in any desired height by again turning up said bolt into said hook.

The pump or oiler is of the usual construction having a piston-rod d1 provided at its 4lower end with a piston or bucket (not shown) IoO and with a spout d, through which oil from the reservoir is lifted by the pump D which discharges through an oil-hole Z212 in the top of the shell B2. The oil-hole Z112 is arranged concentrically with and above an oil-hole in the box B', and is surrounded at the inner end thereof by an annular boss Z113 of less diameter than said last-named oil-hole, to insure the dropping of any oil that may be on the sides of the oil-hole in the shell into the oil-hole in said box. For the same reason, the boss Z313 is tapered at its lower end to a sharp edge, as shown in Fig. 3. The upper end of the piston-rod d19 is provided with a link 017, to receive one arm of a lever ds which turns upon a rod or wire d, which is supported horizontally in the wall of the reser` voir 111.1. The end of the lever d8 farthest from the piston-rod reaches under a cam E, supported upon the shaft F, in such a manner that each revolution of said shaft depresses said last-named end of said lever and raises the piston-rod, the piston-rod being thrown downward or restored to position by a spring 12, (Fig. 5,) substantially as shown in United States patent to me, No. 309,953, dated December 30, 1884. The cam E may be secured to the shaft F in any convenient manner, as by the means shown in United States patent to 1ne,No. 333,950, dated January 5, 1886, where the cam is represented as being secured to theshaft by wires, wrapped around said cam and shaft within grooves in said cam, but is preferably held on the shaft by its own elasticity, as shown and described in United States patent to me, No. 329,904, dated November 10, 1885. The lever d5 is prevented from lateral displacement out of the path of said cam by its connection with the piston-rod, as above described, and also by having arms d10d11, arranged between the fulcrum-rod d1 and the cam E, said arms being extended sufficiently to fill the space between the opposite side-walls of the reservoir, as shown in Fig. 4. The reservoir Z711 is covered by the upper half of the shell and by a cover Z914, hinged at 615 and below said cover and the upper half of the shell are arranged all the parts of the oiler and its operating mechanism, except that the spout d reaches up through a notch (E18 in the cover. The oiler and the journal-box are thus protected from the entrance of dust and lint and the combined apparatus is made in as compact a form as possible and with as few risks of injury from blows.

When the devices abovedescribed are in operation and the oil is lifted by the pump, said oil passes through the oil-hole in the shell and the oil-hole in the box B to the shaft to be lubricated thereby and accumulates in a recess Z218, formed in the upper half of the box by leaving out the anti-friction lining b1 at this place, the surplus oil running out at the ends of said box into said shell, at one end directly into the reservoir, while the oil discharged from the box at the end thereof farthest from the reservoir, flows through the space between said box and outer shell back to said reservoir, the ribs h4 b5 being cut away at the bottom of the shell and box at Z716 b1", as best shown in Figs. 3 and 5, to allow the oil to pass them. It is obvious that the ribs 111125 may be replaced by projections suitably arranged to preventthe movement of the box within the shell.

By the above-described improvement, the bearing is virtually running in an oil-bath, thus lubricating the bearing in the mostperfeet manner known, and the shaft E may be kept sufiiciently lubricated at all times, for months or years, without reiilling the reser- Voir.
