PROVISIONAL SPECIFICATION.
An Improvement in Roller Bearings for Journals and Axle Boxes.
HARRY AUSTIN, Manufacturing Electrician, 5, Florence Terrace, Armley,
near Leeds, Yorkshire, do hereby declare the nature of this invention to be as
follows:-
This invention relates to roller bearings for journals and axle boxes, and has for
its object to provide a simple and effective means for keeping the rollers in true
and proper positions, and for keeping them at suitable distances apart from each
other.
I accomplish this object by using a frame of some suitable material, preferably
gun-metal, the frame consisting of a flat ring or washer, on one or both sides of
which are a suitable number of projecting pieces or fingers, arrainged at suitable
distances apart, each space being bored out to admit a roller easily and allow a
thin layer of oil between the roller and the two concave sides of the projecting
pieces or fingers.

COMPLETE SPECIFICATION.
An Improvement in Roller Bearings for Journals and Axle Boxes.
I, HARRY AUSTIN, Manufacturing Electrician, of No. 5, Florence Terrace,
Armley, near Leeds, in the County of Yorkshire, 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 :-
The object of my invention is to provide a simple and efficient means whereby
the rollers may be kept at suitable distances apart and in a line with the axle.
And the manner in which I accomplish my object is as follows. I make a cylinder
of gun metal or any suitable material as shown in front elevation in Fig. 1, back
elevation in Fig. 2, and in section through line A, B, in Fig. 3. In this cylinder I
bore or drill a suitable number of holes a little larger in diameter than the rollers,
so as to allow the rollers to turn freely.
Fig. 4 is a front elevation, Fig. 5 a back elevation, Fig. 6 a section through
line C, D, and Fig. 10 a view in perspective of a cylinder so made. It will now be
seen that what was at first a plain cylinder is now really a number of double concave
fingers or studs attached to a washer or ring at one end. This I call a guide
frame.
Fig. 7 is a front elevation, Fig. 8 a back elevation, Fig. 9 a section through
line E, F, and Fig. 11 a view in perspective of the frame with the rollers
inserted.
Fig. 12 shows one way in which my invention may be put into practice. G is
the outer case, H the rollers, I the runner, J the axle or spindle, and K the end
washer or ring to which the studs or fingers are attached.
The guide frame may be made a good many different ways according to
requirements. It may be made for instance with the fingers or studs having a
washer or ring at one end only as described, or it may be made with a ring at each
end of the fingers, or one ring may have a set of fingers on both sides, and so on
according to requirements.

page_text: 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 :-
1st. A roller bearing, the rollers of which are kept at suitable distances apart
and in a line with the axle by a guide frame consisting of a suitable number of
.double concave bars of fingers held in position by a ring or rings at one or both
ends, or at any convenient. part or parts. The concave side of one bar or finger
facing the concave side of the next bar or finger, the two concave sides forming
a circular opening to receive, and partly envelope one of the rollers. And so on
all the way round. Each roller being allowed to protrude a little, outside, and
inside of the guide frame, so that the rollers (only) come in contact with the
inside of the outer case or bearing and the central runner or axle. Substantially
Bas:described, and shown, by the drawings.
