EMIL KLAHN, OF WEST HOBOKEN, NEW JERSEY, ASSIGNOR OF ONE-HALF TO GUSTAVUS E. STRAUSS, OF NEW YORK, N. Y.

ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 745,198, dated November 24:, 1903.

Application filed January 2, 1901. Serial No. 41,780. (No model.)

To all whom it may concern.-

Beit known that I, EMILKLAHN, a citizen of the United States of America,residing at West l-Ioboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification.

My invention has reference to improvements in bearings embodying rollers for the purpose of reducing the friction between the contacting partsas, for instance, between a hub and an axle or j0urnala nd has primarily for its object to facilitate the assembling of the rollers in the housing and to secure their retention therein in the most simple and effective manner.

To this end my invention consists in a roller-bearing comprising a housing having flanges containing sockets forming bearings and having contracted openings and rollers having journals adapted to be sprung into said sockets, and said openings being of slightly less width than the diameter of the journals of the rollers, and, furthermore, in a roller-bearing device comprising a series of rollers, a retaining thin metal spider having a central aperture for the shaft and rollerapertures intermediate or between the outer circumference of such metal spider and the shaft-aperture, each of said roller-apertures guarded by a protected passage-way, said passage-way of a slightly smaller diameter than such aperture to retain the rollers in their proper relations when assembled, while per- 3 5 mitting them to be inserted or withdrawn through such opening when desired.

The nature of my invention will best be understood when described in connection with the accompanying drawings, in which- Figure 1 represents a longitudinal central section of a roller-bearing embodying my invention. Fig. 2 is an end view thereof. Fig. 3 is a detail View of one of the rollers. Fig. 4 is a transverse section taken through the housing. Fig. 5 is a longitudinal section,

partly in elevation, showing the bearing applied. Fig. 6 is a longitudinal section with part broken away, illustrating a modified form for the housing. Fig. 7 is a transverse section through the housing shown in Fig. 6.

Similar letters and numerals of reference designate corresponding parts throughout the several views of the drawings.

Referring at present to Figs. 1 to 5, inclusive, of the drawings, the letter A designates the housing, which is intended to receive and retain the rollers 13 and is made in the present instance in the form of a sleeve having circular flanges 1 at its opposite ends. The said flanges are each provided with a series of sockets 2, arranged in circumferential line and adapted to receive the journals 3 of the said rollers 13. The housing instead of being made solid, as usual, is split, as at 4, so that it can be compressed in its periphery. It may be made of steel or-other suitable material possessing the requisite degree of resilience to permit of the necessary peripheral movement. The sockets 2- are formed to correspond to the diameter of the jour- 7o nals 3 at substantially their inner halves, while their outer portions are contracted to form openings or necks 5, of which the adjacent portions are at slightly less distance apart than the diameter of the journals 3. It will therefore be seen that in order to permit the introduction or insertion of the rollers into the sockets 2 the housing A must be able to yield peripherally, so as to permit the spreading of the sockets. This yielding is permitted by the split nature of the housing,

it being readily understood that when the adjacent ends of the housing are brought together the adjacent portions of the openings or necks 5 will diverge. Consequently if a roller is forced against the necks of the opposite sockets the pressure so exerted will force the housing together, and so open the necks to permit the introduction of the roller, while upon the release of the roller the housing 0 again expands and holds the roller in position. In this manner a roller-bearing firmly retaining the rollers against dropping out is formed. The housing is provided with circumferential slots 6, adapted for the lateral passage of the rollers B, so that the latter can bear upon the axle or shaft and also upon the interior of the hub or other bearing. The

roller-bearing so formed may be used for all the purposes which the art requires. In Fig.

5 I have shown the same applied to a hub, in which 0 is the axle, D the hub, E E the supports and bearings for the axle, and 7 7 interposed washers between the roller-bearings and the supports.

While in the preceding figures I have shown the housing provided with outwardly-extending flanges having sockets for the journals of the rollers, it is of course to be understood that the housing could be provided with inwardly-turned flanges. Such construction I have shown in Figs. 6 and 7, Where 1* designates the inwardly-turned flanges. In this construction the housing is expanded by the pressure of introducing the rollers instead of contracted, as before, but with the same result-to wit, the opening of the necks 5.

It will be understood from the foregoing description that the essential feature of my invention is a spring-housing which can contract or expand peripherally for the purpose of permitting the rollers to be readily inserted and to cause the roller-bearing to accommodate itself to the hub.

What I claim as new is- 1. A roller-bearing comprising a housing having flanges containing sockets forming bearings and having contracted openings, and rollers having journals adapted to be sprung into said sockets, and said openings being of slightly less width than the diameter of the journals of the rollers, substantially as described.

2. A roller-bearing comprising a housing having flanges containing sockets forming bearingsand having contracted openings, and said housing being split longitudinally, and rollers having journals adapted to be sprung into said sockets; said openings being of slightly less width than the diameter of the journals of the rollers, substantially as described.

3. A roller-bearing device, comprising a series of rollers, a retaining thin metal spider, having a central aperture for the shaft and roller apertures intermediate or between the outer circumference of such metal spider and the shaft-aperture, each of said rollerapertures guarded by a protected passageway, said passage-way of a slightly smaller diameter than such aperture, to retain the rollers in their proper relations when assembled, while permitting them to be inserted or withdrawn through such opening when desired.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

EMIL KLAHN.
