pressed and then forced into the seats a and b of the box, so that the exposed longitudinal edges of the mica sheet on the concave surface of the bearing are longitudinal to the axis of the shaft, while the transverse section of the sheets is substantially radial to the shaft center. This causes the surface of revolution of the shaft to pass over the edges of the sheets at right angles to the sheets, so that it has no disturbing action or tendency to move the Sheets over each other.
In preparing the composite mica block each sheet 8 is roughened by minute surface scorings (seen in Fig. 4) and then thoroughly cleaned by acid of all objectionable adhering matter, and all traces of acid are removed by washing with water in which, preferably, a little neutralizing alkali is used. The sheets are then dried and afterward treated with a coating of oil and glycerin. The sheets are then assembled and compressed and forced into the seats a b. The seats a b are close together, but are separated by a thin wall of the body metal of the boxing, as seen at c. all the mica blocks are cesses the two halves tened together, and a drill or boring-tool of the size of the shaft is entered into the cen tral cavity, and the shaft-hole is bored out perfectly true, and all the rough edges of the mica blocks and intervening walls 0 of metal are turned clean and smooth, so that the composite mica block appears as a smooth clean hard inlaid mineral bearing-surface, against which the shaft turns. By scoring the mica sheets before assembling them they hang together with a certain interlocking effect of friction, so that they are more firmly held against slipping over each other, and the treatment with oil gives slight permanent lubricating layers at the exposed edge of the block, while the glycerin keeps the oil soft and free from gumming and hardening.
With a journal-bearing constructed in the manner described the shaft needs no oil or other lubricant. There is practically no wear and no heating'eifect, and as the mica is a non-conductor of heat and practically indestructible as against the influence of heat it forms a permanent, durable, and almost frictionless bearing.
The seats a b of the boxing, as shown, are
To all whom it may concern.-
Be it known that I, FRED LATULIP, a citi- Zen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in J ournal-Bearings, of which the following is a specification.
My invention is in the nature of a new journal-bearing for shaftings and other moving surfaces which is designed to have great enduring qualities with but little friction and which requires no repeated lubrication and does not heat.
In constructing my journal-bearing I employ rubbing-surfaces of mica set edgewise to the revolving surfaces. Mica has been here tofore employed for this purpose, but hasg'not as heretofore used been satisfactory on' account of the difliculty of retaining and holding in place the thin laminae of mica which by reason of their smooth surfaces are liable to slip upon each other.
My invention consists in the novel arrange ment of the blocks of mica sheets and in the treatment of the same desi ned to secure the coherence ofthe sheets and the unity of the block as a composite structure, as hereinafter fully described with reference to the drawings, in which Figure 1 is a sectional view of a shaft-bearing, the section being taken at right angles to the lon itudinal axis of the shaft. Fig. 2 is an inside face view of the lower half of the bearing. Fig. 3 is a detail view in perspective of one of the composite mica blocks which is held in one of the recesses or seats of the metal boxing, and Fig. 4 is a view of one of the mica sheets of said block.
In the drawings, A and B are the two metal parts of the journal-box, which are fitted to embrace the shaftor journal and which are secured together by bolts 0 in any desired manner. On the inner concave faces of the box are formed longitudinal recesses or grooves a and b, which are planed or milled out to form seats to receive the mica blocks, one of which is shown'in detail view in Fig. 3 and which blocks are shown in place in the seats of the box in Figs. 1 and 2.
The mica blocks are of a composite character, being formed of any desired number of the thin layers, sheets, or laminae of mica placed together in parallel position and comseated Within their reof the boxing are fas-- cent surfaces and having the roughened scorings filled. with a lubricant, said sheets being compressed into a composite block, and a metal body having, a seat for the said block, 15 the mica. block being arranged in the metal ple sheets of mica roughened on t eir ad abody with the sheets ofmica at right angles cent surfaces and having the roughened scorto the direction of motion.
