Specification forming part of Letters Patent No. 1,390, dated October 31, 1F39; Reissue No. 63, `dated June 13, 1844.

To all whom it may concern,.-

Beit known that I, JOHN H. TIMs, of Newark, in the county of Essex and State of New Jersey, have invented a new, useful, and Im- I proved Method of Constructing the Bearings and Oil-Boxes for Lubricating the Journals of l the Axles of Railroad-Cars, Locomotives, &c., which have their bearings on t pper side of their journals; and I do hereb clare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, in which Figure A is a perspective drawing, Fig. B a vertical sectionand Fig. C a. longitudinal section of the journal and axle.

Reference is made on said drawings to the dierent parts in marginal notes.

When this box is constructed for cars' or locomotives having outside bearings, it is formed as represented in the figures above mentioned. For inside bearings the parts must necessarily undergo such modifications as are requisite to adapt the box and its appendages thereto.

u A represents the top or spring-bed ofthe box, and 1 1 1 the outer shell.

Bis a brass or composition step that bears on the journal and fits the upper side of the box inside, on which there is a projecting check, 10, at the outer end that tits into a corresponding recess in the box-top. At the inner end of the step 3 there is a groove cut and a fillet, 4, formed upon the bearing, which fillet enters into a corresponding groove, 5, in the journal, which will aid in sustaining the lateral pressure and in preventing wear fromk this cause, co-op'erating with the ordinary collars upon the ends of the axles in effecting this object. The opening in front of the box through which the journal passes I cover by means-of a leather cap or washer, 7, which is secured around the opening by a metal ring, 8, held in its place by screws 9. The inner edge of this leather cap is received into a groove, 6, turned in the journal for that purpose, thus retaining the oil within the box and prevent.- from without. Additional grooves, 19 19, are turned next the hub outside the cap, to turn the water and dirt from the box toward the hub.

close to constitute the oil-chamber, and this hollow space is divided into twocompartments, C and B, for containing the oil, the division between the two being made by the partition 2 2, extending up from the bottom of the box, but terminating above, as shown in the drawings, in such a. manner as that the oil contained in B may flow over into C, as indicated by the arrow. A sponge or other absorbent elastic material-such ascotton waste, &c.-is placed in the compartment B, the compartment C being empty, or Without such elastic packing. The elastic material lills the compartment B and bears up against the lower side of the journal G G, which is to be kept lubricated by the oil contained in the sponge, which is supplied projection on the front end of the box F, said tube being closed by a faucet, 15, the handle 16 of which keeps the faucet closed. 12 is a horizontal tube leading from chamber G to the front under chamber, B. Itis stopped with a faucet, 13, acted on by handle 14, similar to the one above named.

Vhen oil is to be supplied for oiling the journals, the faucet 15 is opened and the oil poured in through the tube 11 into the compartment or supply-chamber/B. When the sponge orother material is saturated and compartment B filled, the oil will run over the partition 2 2 into compartment C, as indicated by the arrow. This maybe known by opening faucet 13, at which the oil will run out. After it begins to run over the supply-chamber should then be closed. After the oil from the other or receiving-chamber is all drawn o, the lower faucet, 12, is also closed and kept so by the gravity of the handle 14. On the side of the box E next the hub there is a projection, 20, inward, just under the hole where the journal goes through, so formed that the oil contained in the saving-chamber C shall not, when agitated by the motion of the car,

back again into the compartment.

The difference in the characteristic features of my oil-box and bearings for journals and those which have been'heretofore employed will be manifest to every competent, machinist. They are, first, the applying the oil to Below the journal the box is made hollow and the under side of the journal without rst passthrough an aperture or tube, 11, formed in a splash over toward the hub, but be thrown ing over the upper side of the journal through a hole in the step or bearing, thereby obviating all 'the diicultes arising from the filling up of` said apertures, which they almost uniformly do shortly after having been put in order. By my improvement the oil is applied to the lower side of the journal. and there are not any conduits through which the oil is to flow that are liable to be stopped up or accidentally obstructed so as to prevent a regular supply of oil at all times without waste, this being e'ected by means of the saving-chamber C. All dust and dirt are kept out of the box by means of the cap 7 and grooves 6.

It will be evident that the forni of the respective parts will admit of considerable variation, While the general operation and principle of action may remain unchanged. I do not, therefore, by the foregoing specification intend to limit myself to the precise form and arrangement which I have described and exhibited; but I design to vary them as I may think proper while the same ends are obtained byanalogous means.

Having thus fully described my improvements, I wish it tobe fully understood that I do not claim as my invention the supplying of oil to the journals of axles by means of sponge or other similar substance, as that has before been done; nor do I claim the invention of a cup or saving-chamber placed under the bearing of a journal, as cups open and exi posed to the dirt and from which the oil could be spilled by the jar of the car in motion have been used. Neither'do I claim a washer nor cap from the hub of a Wheel, as that is now applied to common carriages; but

What I do claim as my invention, and for which I desire Letters Patent, is

1. Constructing the box in the manner described, having two recesses or compartments in its lower section, into one of which, B, sponge or other suitable elastic substance is fitted so as when saturated with oil to lubricate the journal with which it comes in contact, the other chamber, C, being made to receive the oil that ilows'ovcr from compartment B, the oil being conveyed to said chambers through a conductor that enters the supply-chamber B under the journal, the whole being combined substantially as herein set forth.

2. The particular manner in which I have constructed the journal and its bearings, grooves, and cap in combination with the foregoing lubricating apparatus, consisting in thellet ngue, and the recess in the bearings for c ecking the lateral motion of the bearing, and the grooves and washer for retaining the oil, in combination, asset forth.
