I, FRANCIS ANGELO PILKINGTON, of 43, Sinderland Lane, Broadheath, in the
County of Chester, Engineer, 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;-
This invention relates to an improvement in roller bearings such as are em-
ployed in machinery or shafting. The object of this my mnvention is to enable
said roller bearings to be adjusted when from wear or other causes adjustment
may be necessary I attain this object by the means hereinafter described, refer-
ence being made to the accompanying sheet of drawings in which Fig. 1 is a
longitudinal section of a roller bearing that is formed or constructed according to
my invention fitted to a shaft: Fig. is partly an end view and partly a trans-
verse section of the same bearing; the remaining Figures to 12 are details of the
several parts constituting the aforesaid bearing.
In these views similar letters refer to similar parts
In this invention I construct a cradle as a Figs 3 and 4 which are respectively
a side view and transverse section of said cradle. the ends a¹ are formed of an
internal diameter to fit on a spindle or a shaft as b but not so as to bind thereon:
the number of divisions a² which are parallel with the shaft is determined by the
size of the spindle or shaft b, or the rollers c: I make the rollers shown in Figs. 5
and 6 of a length to fit into and between the divisions a² and form a
bearing for
the shaft. I form a groove c¹ at one end of each of said rollers, and fit therein a
flat washer as that is split transversely, said washer may be placed therein by
passing the groove or neck of each roller through the split portions shown in
Figs. 7 and 8 which are respectively side and end views of said washer, and then
slipping each roller round the shaft by revolving the cradle a but not the washer d;
I place a row of split rings as e represented by Figs 9 and 10 around the rollers e
by which said rollers are retained on the shaft b. In order to give the necessary
compression to the aforesaid split rings and thereby either tighten or case the
roller bearings, I make the interior of the boss f of a taper form as shown in Fig 1,
or of an internal diameter that is larger on one side than on the other: I con-
struct a split sleeve as y represented by the side and end views shown in Figs. 11
and 12 that is bored parallel, but whose periphery is cone-shaped, or of the same
taper as the interior of the boss f. I form a screw thread on each end of the said
sleeve and fit screw nuts thereon as g³ ³ at one end of the sleeve g I fit a screwed
ring into a recess that has an internal screw thread formed therein
In apply-

page_text: ing my invention I pass the shaft or spindle through the cradle a and place in
said cradle, rollers as c parallel with and in contact with the shaft, securing their
grooved ends by the split ring or washer d. I place split rings as e over and
around the aforesaid rollers. I then place the cradle a with the rollers c and the
ring or washer d within the sleeve g: the rings c are prevented turning round in
the sleeve by a pin el projecting from each ring into said sleeve as in Fig. 2.
I then screw the ring against the plate or washer d I place the bearing
thus formed within the boss f and apply the necessary compression to the split
ings e by screwing up the nut g3; the nut 2 is then tightened and the nut
thereby locked; the aforesaid sleeve g is prevented turning round in the boss f by
a set pin that is passed through the boss. In order to compensate for any wear
in the bearings herein before described the nut 2 is slackened and the sleeveg
drawn within the boss by the nut g³ a sufficient distance to compress the split
rings e as much as may be required. I am aware that prior to my invention roller
bearings have been constructed so as to be capable of adjustment.
I therefore desire to restrict myself to the combination I have herem before
described, and shown on the accompanying drawing.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Roller bearings such as are employed in machinery or shafting constructed so
as to be adjustable by a combination with rollers as c placed in a cradle as a, split
rings as d and e, a split cone sleeve as g, and an internally tapered boss as f, all
for the purpose and in the manner substantially as herein before described.
