Improvements in Ball Bearings.
A communication to me from EUGEN ROTHER, of Goerlitz, in the Empire of
Germany, Architect.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention has for its objects improvements in ball bearings for shafts,
crank pins, and the like, so that all the advantages of a good bearing, easy
movement, very little friction, and simple and effective lubrication are combined.
In one form of the improved ball bearing, the lower part of a plummer block or
support is combined with the upper part or cap in the ordinary way, but instead of
the usual brasses, recesses of sufficient depth are formed round the shaft, both in
the lower bearing and in a lining fitted into the cap, the edges of the recesses
having narrow annular projections extending nearly or quite to the shaft.
In the recesses described are placed balls of a sufficient number to fill the entire
space round the shaft, so that any jamming of the balls cannot take place.
The bearing, thus formed by the balls arranged as described, causes a very easy
movement of the shaft and good lubrication with a small consumption of oil..
The oiling is effected by means of an ordinary lubricator fitted in the top of the
bearing, the oil passing down through a hole in the upper lining. The oil which.
has been used may be drawn off by a cock from the bottom bearing, and the whole.
bearing can be cleaned in a very short time.
In another slightly modified form of the improved bearing, the upper and lower-
parts, instead of being recessed as above described, have parallel grooves formed.
round them to receive the balls in separate parallel rows, narrow ribs separating
the grooves.
In this way the balls are guided in the proper positions round the
shaft, and the lubricating oil is supplied and retained in the same way as in the
arrangement first described.

Improvements in Ball Bearings.
A communication to me from EUGEN ROTHER, of Goerlitz, in the Empire of
Germany, Architect.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of this invention, and in what manner the same is to be.
performed, to be particularly described and ascertained in and by the following
statement, and accompanying drawing, that is to say :—
This invention has for its objects improvements in ball bearings for shafts,.

page_text: crankpins, and the like, so that all the advantages of a good bearing, easy
movement, very little friction, and simple and effective lubrication are combined.
In the accompanying drawing, which is in illustration of the invention,
Figures 1 and 2 represent transverse and longitudinal sections through the
bearing.
Figure 3 shews the arrangement of the balls, their curved position being
_developed for clearness, to-a-plane-surface.
Figures 4 and 5 shew a somewhat different arrangement, in which the balls run in
separate grooves in the bearing.
In the form of the improved ball bearing illustrated in Figures 1, 2, and 3, the
lower part a of a plummer block or support is combined with the upper part
or cap in the ordinary way, but instead of the usual brasses, recesses of sufficient
depth are formed round the shaft, both in the lower bearing and in a lining g fitted
into the cap b, the edges of the recesses having narrow annular projections, a', a²,
below, and g', g² above, extending nearly or quite to the shaft, d.
In the recesses described are placed balls k sufficient in number to fill the entire
space round the shaft, (as illustrated in Figure 3) so that any jamming of the balls
cannot take place.
The bearing, thus formed by the balls arranged as described, ensures a very easy
movement of the shaft d, and good lubrication with a small consumption of oil.
The oiling is effected by means of an ordinary lubricator fitted in the top of the
bearing, the oil passing down through a hole in the upper lining. The oil which
has been used may be drawn off by a cock h (Figure 2) from the bottom bearing,
and the whole bearing can be cleaned in a very short time.
r
In another slightly modified form of the improved bearing, illustrated in
Figures 4 and 5, the upper and lower parts e and f, instead of being recessed
as above described, have parallel grooves formed round them to receive the balls k
in separate parallel rows, narrow ribs ¹, f², f³, below, and e', e², e³, above,
separating the grooves. In this way the balls k are guided in the proper positions
round the shaft d. The lubricating oil is supplied and retained in the same way as
in the arrangement first described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is =
1. The ball bearing for rotating shafts, consisting of several rows of balls k,
revolving freely in recesses in the lower and upper part of a plummer block formed
by the projecting ribs a¹, a², and g', 93, so that the balls entirely fill the recesses,
and ensure an easy rotation of the shaft with little friction, substantially as described
and illustrated in Figures 1, 2, and 3.
2. The modification of the arrangement described in Claim 1, consisting of
ribs e, e, e³, and f,f,f³, forming separate grooves for several rows of balls,
substantially as described and illustrated in Figures 4 and 5.
