UNITED sTATEs PATENT onirica. i
THOS. HOPPER AND THOS. GARRISON, OF VNEW BRUNSWICK, NEW JERSEY.
JOURNAL AND B0X.
To al] whom, may concern Be it known that we, THOMAS HorrnR 'and THOMAS GARRIsoN, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new and useful apparatus which he denominate Antifriction-Box, and that the following is a full, clear, and exactdescription of the principle or character which distinguishes it from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawing, which forms a part thereof, in which- Figure l is an end elevation. Fig. 2 is a top plan with a portion of the outer cylinder removed to show t-he arrangement of the blocks or rollers.
The nature of ourimprovement consists in arranging around a journal, suitable for the purpose intended, a series of wheels, which we denominate blocks, that traverse around a vstationary including cylinder, which is connected with the frame in any of the usual ways. The exterior surface of the journals and blocks, and also the interior surface of the cylindrical casing being grooved, so as to form what are generally are at right angles, or nearly so, to each other.
The construction is as follows, reference being made to the drawing as' above stated:
(a, a) is a portion of the frame; (mais aVA short hollow cylinder, open at both ends, which may be constructed in two parts. and bolted together, as shown in the drawing; or it may be made in one, or any number of pieces; it is grooved on its inner surface from end to end, with miter grooves, asv
above stated. Concentric with this, and at its center the journal (o) is placed; this journal may either be made with the grooves cut into it, or a thimble maybe fitted onto it, in which said grooves are cut; around the journal, and between it and the exterior cylinder, we place two series of rollers d, each series being made of a length equal to one-half of the length of the cylinder. We propose sometimes to vary the number of series and may use a` greater number of series than two, in which case they are made proportionally shorter, so that all the series called miter teeth, the two faces of whichl combined will be equal to the length of the including cylinder. rl`he number of rollers in each series may vary according to cir# cumstances, and the purpose to'which they are to be applied. 1n the drawing there are four in each series, and the two series are made to break joint with each other, as is clearly represented in Fig. 2; thus always having a block in position to resist the downward pressure without too much binding strain on the preceding blocks; by this ar-k rangement all the parts are made to run without the friction of rubbing surfaces, and may run without oil or otherlubricator, as has been experimentally demonstrated at high velocities. Each one of these rollers being independent, kand no oil or'other lubricator beingnecessary,-`the whole front can be made to open, as shown in the red lines.
Fig. 1, and any one ofthe rollersvremoved,
if found defective, and replaced by a per# fect one, which cannot be done with those' boxes when the series arek attached togetherv u,
or cogged.
Some attempts to relieve the friction by plain' rollers, which break joint in a similar manner to'ours, but they soon get to crowd upon each other and bind which at once creates friction and heats the parts, thus rendering vit impossible to run without a lubricator, or if the Whole series are connected bya ring and there is any difference in their. size caused by wear or otherwise a friction of rubbing parts is `at once created. Anotherplan has'been to combine cogs with smooth rollers in one] piece,
practice it cannot be effected without cans-'i but it will at-once be seenthat` in haveheretofore been made i ing the surfaces to rub, for the number of revolutions the rollers turn ontheir own axes in going once around the journal is governed and limited, kwhile the smooth sur face must vary by wear; all these devices4 therefore are subject tok become-heated in` consequence oftheir surfaces rubbing. y
By our improved construction we possess the advantage of a rolling surface and at the same time by the shape of the tooth present a great bearing surface not liable tobe crushed and one which it is impossible Y to' make bind as would be the caseif the' ordinary cog were employed.
Having thus fully described our improved c j antifriction journals and their mode of operation what We claim therein as new, and for which We desire to secure Letters Patent 1s- Supporting the boX or journal upon the series of miter grooved rollers or blocks, Working into similar grooves on the journal and bearing said rollers being Without j our'- nals, and the Whole being constructed and arranged substantially in the manner and for the purposes set forth.
