UNITED STATES PATENT OFFICE.
GEORGE W. SWEENEY, OF NEW YORK, N. Y.
IMPROVEMENT IN JOURNAL-BOXES.
Specification forming part of Letters Patent No. 191AS9, dated May 29, 1877; application filed November 25, 1876.
To au whom it may concrn:
Be it known that l, GEORGE W. SWEENEY, of the city,county, and State of New York, have invented a new and useful improvement in J ournal-Boxes, which improvement is fully set forth in the following specification, reference being had to .the accompanying drawing, in which- Figure 1 represents a transverse section of a journal-box constructed according to my inventon. Fig. 2 is a modification of the same. Figs. 3, 4:, 5, and 6 are transverse sections, respectively, in the planes x w, y y, z z, w' w', Fig. 2.
Similar letters indicate corresponding parts.
Thisinventionrelates to a journal-box which is lined with wood, the pieces of Wood which compose this lining being preferably so arranged that the bearingsurface of the box is forned by the endgrains of the pieces of Wood which compose the lining, or nearly so, said lining being provided with recesses-one or more-for the reception of a lubricating coniound of graphite and collodion, or ny other lubricating compound of a similar nature, whe'eby the box is rendered self-lubricating, thereby producing a journal-box which will wear uniformly throughout, and which can be used with great advantage for all classes of machinery.
In the drawing, the letter A designates a journal-box which is provided with aliuing of wood. In the example shown in Fig. l this lining is composed ot' pieces of' Wood w b c, which are so placed that the grains of the pieces a and c run at right angles'toward the grains of the pieces b, and, consequently, the hearing-surface of the bo'x is formed by the end grains of the pieces of Wood composing the lining, The same result is obtained by arranging the lining in the manner shown in Figs.2 to 6, inclusive. In this case the lining is composed of a series of pieces of wood, d, e, f, g, &c., which are so placed that the grains of the pieces d run in a vertical direction, as shown in Fig. 3, the grains of the pieces e in a diagonal direction, as shown in Fig. 4,
the grains of the pieces f in a horizontal direction, as shown in Fig. 5, and the grains of the pieces g in a diagonal direction, at right augles to the direction of the graius of the pieces e. (See Fig. 6.) The pieces d, e, f, and g, which are used in forming this lining, are intended to be of small thickness, so that a large number of such pieces is required to form the entire lining, and by arranging these pieces as above stated it will be seen that the largest portion of the hearing-surface of the box is fol-med by the end grains of the pieces of wood which compose the liuing.
In the lining ot' my box are formed suitable recesses h, preferably ot' a dovetniled form, which are filled with a lubreating compound of graphite and collodio, or with any other equivalent dry lubricator, so that when the journal revolves in the box the end grains ot' the wood lining will soon become coated with the lubricating compound, and a journal-box is obtained which requires no oil, and which will not be liab.e to heat, even it' the journal is revolved with great speed.
My journal-box can be made with comparzttively little expense, and it is not liable to wear uneveu, since tsbearing-surface is composed of the end graius of the wood, which, when coated with a suitable lubricating conipound, will not wear.
What l claim as new, and desire to secure by Letters Paten t, is
A journal-box the hearing-surface of which is fol-med by the end g-ains of the pieces ot' wood which compose its lining, and which is provided with recesses h one or more for the reception of a dry lubricating compound, substantially as and for the purpose herein set forth.
ln testimony that I claim the t'oregoing l have hereunto set my hand and seal this 16th day of November, 1876.
GEORGE W. SWEENEY. [L. 5.]
