IMPROVEMENT m JOURNAL-BOXES.

Specification forming part of Letters Patent No. 183,776, dated December 10, 1872.

' To all whom it may concern:

Be it known that I, J. HENRYHAYWARD,

of the city, county, and State of New York,

have made certain Improvements in the Method of Constructing and Manufacturing J ournal-Boxes for railroad, marine, and stationary machinery, of which the following is a specification:

Nature and Objects of thelncention Are to decrease the friction-surface of the journal-bearingupon the journal without weakenin g or disturbing the relative condition of the styles at present in use; that by thus remetal (case-hardened) or steel may be used in lieu of cast metal to insure strength and durability, and at the same time supply a means whereby the journal-bearing so improved may be manufactured more rapidly, in duplicate, and at a greatly reduced amount of labor and cost.

Description of the Acconwanying Drawing.

Figure No. 1 is an end elevation of the jour nal plates. Fig. No. 2 shows the plates in combination, also journal-bearing surface. Fig. 3 is a plan of the. upper side or oil-cup portion of the same. Figs. Nos-4 and 5 show another Figs. Nos. 6

General Description.

Figs. Nos. 1, 2, 3 are three views of the same journal-box.

A are plates of rolled, cast, or forged metal, of any desired kind, quality, or thickness, cut into the requisite form by means of dies and punches operated by pressure, each'plate consequently being an exact duplicate of theother so as not even requiring retouching by a file. Each j ournal-box, as represented in Figs. 1, 2, 3, is composed of eight plates, A A, (more or less,) to wit: three right and three left re cessed platesfalso two outside plates, as shown in Fig. No. 2. These plates are firmly bolted or keyed, or otherwise held securely together in such a manner as to be, for all ordinary purposes, one piece, as shown, by bolts B B B. The object of cutting the plates of this box right and left is that where the friction and heating surface is reduced just one-half, and the lubricating-surface increased in just proportion, there will be at the same time no con traction of the journal-bearing surface, while the wear upon the journalor axle will be properly distributed the same as though the bearing-surface was solid, as in the old style.

Fig. No. 3 is a viewof the top side of the box, which shows that each plate A is cut to the full height and length of the box, for the purpose of insuring increased strength, it required, the intermediate plates A A A A be ing cut at angles or arched inward so'as to form recesses D D D D for the deposit of oil, which passes freely down throu h the drip holes E E E E.

As will be seen, the drip-holes are, in all cases, put in the recessed side of the plate, for by this means the orifice is at all times above the friction and heating surface of the axle, and is not, therefore, liable to become filled or gummed up, as must always happen where the orifice comes directly in contact with the axle.

As will be seen in Figs. 6 and '4', the oil may be conveyed to the axle by means of any suit able material to absorb it from the oil-cup, as at F, Figs. 6 and 7. It may also be found advantageous to fill the recesses formed by the alternate plates with suitable packing, especially those in the bottom half of the journalbox, so as to retain and keep the oilinsuspension after it has passed down from the top. Also, when the plates are cut as in Figs. 6 and 7, the top and bottom half of the boxes are to be of a right and left alternate bearing'surface so as to equalize the wear on the axle.

This combination of plates, so cut and secured together, constitutes the elementary form of my invention, which is susceptible of nunierous modifications, as exemplified in Figs. 4, 5, 6, 7, each and all being in substance and efl'ect the same; and although the permanent design of my invention in thus constructing the series of plates is for the purpose set forth,

still the same principle of decrease of friction and heating surfaces, without contraction of bearing-surface, with enlarged lubricating-surface, may be etfected in the cast orsolid jour-. nal-box new used.

I claim as my invention 1. The construction of journal-bearings of a combination of plates, substantially as and for the purposes herein set forth.

2. The plates A A, cut so as to form recesses in the bearing-surfaces of journal-boxes, substantially as shown in Fig. 4, for the purpose set forth.

3. A journal-boxconstructed with alternating bearing-surfaces and recesses, in the manner described, and said recesses filled with suitable packing to retain the lubricant, as set forth.

4. A journal-box constructed with alternating bearing-surfaces and recesses D, as described, and provided with drip-holes E, located in said recesses, as set forth.
