SPECIFICATIQN forming part of Letters Patent No. 7 30,77 3, dated J' une 9, 1903. Applicaubnfiiearanumy12,1903. serai 110.138.708. cromati.:
To all whom, it may concern.-
Be it known that I, JOHN KINCAID, a citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented a new and useful Improvement in Roller-Bearings,of which the following is a specification.
My invention relates to the application of roller-bearings to the requirements of relatively heavy loads, such as are incidental to ordinary steam-engine zpractice; and it consists, primarily, in the particularconstruction of the rollers themselves and in its complete form of the means by which their aline-V radial cross-section side by side on spindlesl which are maintained the proper distance apart by an exterior framework into which the .spindles are secured, the rolling surfaces of the moving parts of the machine in which it is desired to introduce, them being provided with parallel grooves in the line of motion adapted in cross-section to the V form of the rollers.
My invention is fully described in the following specication and illustrated in the drawings which accompany it, Figure 1 being a side elevation of an engine cross-head and guide-bars having my roller-bearings applied to the lower or foregoing bar; Fig. 2, a crosssection of the roller-bearing of the same; Fig. 3, a side elevation showing the application of my rollers to a crank-pin bearing, and Fig. 4 a cross-section of the same.
In Figs. l and 2, illustrating the application of my roller-bearings to an engine crosshead, the cross-head is represented by c, the guide-bar by b, and the intermediate rollers by 3. The particular form of these rollers is clearly illustrated in Fig. 2, the opposite sides being somewhat as drawn and the slope of the sides such as will preclude the possibility of any side binding due to the Wedging tendency. Each roller is bored, and they are arranged side by side on spindles 5 in such number as to suit the requirements of the pressure between the surfaces, the ends of the spindles being secured in side members 6 of a rectangular frame, by means of which the longitudinal spacing of the rollers is maintained. The surfaces of both the cross-head and the guide-bar with which the rollers engage are provided with a series of longitudinal grooves c2 b2, corresponding to the number of rollers on each spindle and in shape accurately fitted to the radial cross-section of the rollers. These 'grooves will keep the rollers laterally in place, and the combination of rollers and grooves will preserve the alinement of the moving parts. I prefer that the bottom of the grooves have a deepened parallel portion, as at 4, so as to insure the rollers bearing only on the inclined sides and not on the cylindrical periphery. With the application of strain consequent on thisconstruction of rollers and grooves it is obvious that the roller is individually a particularly strong one and one that can be hardened or tempered without risk of serious distortion, that having a short rolling base it will not be subject to the evil of cross-winding, and its ample lateral support in the grooves willl preclude the possibility of it turning over sidewise, as a roller of such shortness in relation to diameter would otherwise be very liable to do.
Another advantage of my system is that although I may use a roller of considerable diameter I do not require to similarly increase the distance from center of cross-head pin to outside of bar, as the ridges between the grooves will serve to maintain to a considerable extent the strength of the respective parts.
In the application of my system of roller construction to the requirements of a crank.- pin, eccentric, or ordinary journal-bearing there is little dierence in the construction other than that necessitated by the cylindrical form of the rolling-surfaces.
Figs. 3 and 4 illustrate in front elevationi IOO and cross-section the application to a crankpin bearing as typical of the class, the connecting-rod end'being represented by fr and the crank-pin by p, the rollers being, as before, indicated by 3 and the grooves by T2122.
The supports of the roller-carrying frame may be rings, as 8 in Fig. 4, and 'maybe made either in one piece, as drawn, or for convenience of removal in two or more segments;
but for the front support of an end bearing.l
l no attempt has heretofore been made to provide a bearing, such as I have described, in(
which the entire pressure on the bearing has been borne on the conical sides of a series of short rollers so supported with spindle and frames.
I therefore declare that what I claim as A s l n 730,77?,
new, and desire to beprotected in by Letters Patent, is-v Y'. l f
A roller-bearing for the purposes described,
comprising a pair of opposing surfacesv said surfaces having a series of opposing V-shaped grooves, the grooves of one surface being disposed in alinement with the grooves of the other surface, each surface having supplemental grooves at the bottom of theV-shaped grooves; 'a frameworkk having crossed spin-- dles, a series of double cone-rollers upon each cross-spindle, said rollersY including a cylindrical portion at the intersection of the conesurfaces, said cylindrical portion being of a .Width equal that of the supplemental grooves in the opposing-surfaces, the ksides of each roller being adapted .tofit in the opposing grooves and to bear on the V-shaped surfaces thereof,substantially asshown and described.
In testimony whereof I have signed my 4name to this specification in the presence of two subscribing witnesses.
JOHN KINOAID. In presence of n W. H. R. OALLIsTER, RowLAND BRITTAIN.
