I nouns-BEARING.

To all whom it may concern:

Be it known that I, FRANKLIN STRAITON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Roller- Bearings, of which the following is a specification. I l V i This invention relates to an anti-friction hearing, and

.more particularly to atelier-bearing having its rollers which is strong, durable, easily applied and removed,

which assures a smooth and even motion to the revolving part having contact therewith; and in which binding and uneven wear is entirely prevented.

To this end the invention consists in the construction, arrangement, and combination of parts te -be herea inafter described and particularly pointed out in the subjoined claims. 7 i H 5 Referring to the drawingsplike numerals of referenc refer to like parts in the several figures. p v Figure 1 is a side elevation of myimproved bearing applied to a shaft or axle. Fig. 2 isa cross-section taken on line y-y, Fig. 1. Fig. 3 is an enlarged central vertical section of the roller-bearing} Fig. 4 is an inner side view of one of the annular roller-supports. Fig. 5

is a section taken on line,zf z, Fig. 4,1o6kinginthe direction of the arrow crossing said line. fdis anelevation of one of the solid bearing-rollers. I Fig. 7 is an elevation of one of the sp'acingjollersi Fig. 8 is a longitudinal section of one of the hollow bearing-rollers. Fig. 9 is an elevation of one of the tie-rods around which the hollow bearing-rollers revolve. I

The numeral 1 designates a shaft or axle to which my improved roller-bearing 2 is applied. Obviously, the shaft may revolve within the roller-bearing and the whole held within a box, or the shaft may be stationary and anobject, such as a wheeler the like, revolve on the roller'bearing. i I Y My improved bearing comprises two-bearing-rings 3 which are exact counterparts, an annular series of bear ing-rollers comprising solid'rollers 4 and hollow rollers 4, which are spaced equidistantly around the bearingrings, and spacing-rollers 5 interposed between the bearing-rollers and in contact therewith. The bearingrings are of a width somewhat greater than the diameter of the spacing-rollers but narrower than the bearingrollers, and each ring has its inner face provided with I sockets or depressions 6 open at the edges of the ring and apertures 7 central of said sockets. Between said' sockets or'depressions'are arranged sockets or depressions 8 which are circular in formation and smaller than .Speeification of Letters Patent.

the sockets 6 but preferably of the same depth; each having an aperture 9 arranged central thereof. The diameters of the sockets or depressions 8 are smaller than the width of the bearing-rings and are therefore closed at the edges of said rings. Attention is directed to the fact that the confining walls of the sockets or depressions 6 are in arcs of circles and that the distance between the axes of two adjoining sockets or depressions 6 and -8 is less than the combined radii of said sockets so that they communicate at 10. Two or more of the apertures 9 are countersunk on the outer faces of the bearing-rings, as at 11, three such apertures being shown in the drawings.

At points where the countersink apertures are located, the hollow bearing-rollers 4. are located, as clearly shown at 12, in Figs. 2 and 3. Through said hollow bearing-rollers, tie-rods 13 are passed which have their ends reduced, as at 14 toform shoulders 15, the reduced ends fitting the countersink apertures in the bearing-rings and the shoulders bearing against the inner socketed sides of said rings. Said tie-rods have their ends countersunk into the countersink apertures 9 so that they properly space and securely connect the bearing-rings. This assures a free motion to the hollow bearing-rollers, which have their ends fitting into the sockets 6 through which tie-rods are passed and in,

a minimum the frictional contact thereof with the inner walls of said sockets. The ends of the hollow bearingrollers are similarly beveled,.as at 19, for the same purpose. It is to be noted that the degree of bevel at the 1 ends of the bearing-rollers is less than the depth of the sockets in which they are seated, so that the cylindrical extremities of the body portion of said rollersare confined within the Walls of said sockets, this assuring proper retention and centering of the rollers within said sockets. By reason of the bearing-rollers being larger-in diameter than the width Bf the bearing-rings,- the circumferentialfaces extend beyond the edges of the latter and are free to contact against surrounding and confined parts, without said parts coming in contact with any other portion of this improved rollerbearing. The spacing-rollers located between the bearingrollers are also provided at their ends with gudgeons 20 which fit into the apertures 9 inthe bearing ringa and the ends of the body-portions 21 of the spacing-rollers fit into the sockets or depressions 8-in said rings and are beveled at 22 to reduce to a minimum the frictionalbody of each spacing-roller is in contact throughout its length with two adjoining bearing-rollers, which prevents deflection oi the latter and takes all strain off the gudgeons of the same. The cylindrical extremities of the body portions of said spacing-rollers are confined within the walls of the sockets 8 similar to the bearing-rollers and for similar purpose.

By means oi this construction most of the bearingrollers can be made solid, as it requires only three tierods to securely connect the bearing-rings in a rigid manner. This greatly simplifies the construction and assures a free acting bearing.

It is not my intention to confine this invention to a cylindrical roller-bearing, as all the novel features of the same may be embodied in'a thrust-bearing which is common in the art and in which two bearing-rings of different sizes are employed with the. bearing-rollers arranged radially between said bearing-rings. The following claims are therefore to be construed without regard to the exact disposition and arrangement of the rollers and bearing-rings, except where in the claims, the disposition and arrangement is specifically recited.

Having thus described my invention, what I claim 1.- A rollerrbearlng comprising an annular series of rollers having gudgeons at opposite ends, connected supports at opposite ends of said rollers having sockets to receive the ends of said rollers and apertures to receive said gu'dgeons.

2. A roller-bearing comprising an annular series of roll ers, part of which are solid and have gudgeons at opposite ends and part of which are hollow, bearing-rings at oppo siteends of said roller-shaving sockets in their inner surfaces and apertures extending therethrough central of said sockets, the ends of said rollers being seated in said sock ets and the gudgeons of the solid rollers fitting their respectlve apertures, and tie rods passed-through said hollow-rollers and entering the corresponding apertures in the bearing-rings to tie-the latter together.

3. A roller-bearing comprising bearing-rings having each a series of sockets open at the inner and outer edges of seam? said rings, and sockets of smaller size between said first mentioned sockets and opening into the latter at opposite points, bearing-rollers having their ends fitting into said first mentioned sockets'and their circumferential surfaces extending beyond the edgesof said bearing-rings, spaclngrollers having their ends fitting into said smaller sockets and in contact throughout their length with said bearingrollers, and means for connecting said bearing-rings.-

'4. A roller-bearing comprising two bearing-rings having each an annular'series of sockets open at the edges-of the rings, sockets of smaller size between said first mentioned sockets, each of said smaller sockets belng'closed at the edges of the bearing-rings but opening at opposite points into twoof the first mentioned sockets, and apertures through said bearing-rings central of said sockets, an unnular series of bearing-rollers having their circumferential surfaces extending beyond the edges of said hearing-rings, part of sald'rollers being solid and having gudgeons at opposite ends and part thereof being hollow, said bearingrollers having their ends fitting said first mentioned sockets and the solid bearing rollers having their gudgeons fitting their respective apertures iii the bearing-rings, tierods passed through the hollow bearing-rollers and having their ends secured in the corresponding apertures in'said bearing-rings, and spacing-rollers between, the bearingrollers and in contact therewith, said spacing-rollers'having g'udgeons at their endsfitting into the apertures in the smaller sockets and having their ends fitting into the last mentioned sockets.

5. A roller-bearing comprising an annular series of roll-' ers part of which are solid and part hollow, supports at opposite ends of said rollers having sockets to receive the ends of the latter and apertures central of the sockets receiving the hollow rollers, and tie-rods passed through the hollow rollers andhaving opposite ends reduced to form shoulders; said tie-rods having their shoulders hearing against the inner walls of the apertured sockets, their reduced ends passed through said apertures, and the extremities of said reduced ends arranged to secure the said supports to said tie-rods.

. In testimony whereof, I have aiilxed my signature in the I presence of two subscribing witnesses.
