I, EDWIN CARVER, of Florence, County of Switzerland, Indiana, U.S.A.,
Inventor, 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:—
My invention has relation to improvements in thrust-bearings and means for
lubricating the same; and the object is to provide a bearing for the end of
a shaft which will resist the thrust of the shaft and at the same time will supply
the requisite lubricant thereto.
In the accompanying drawing Figure 1 is a longitudinal vertical section
through the bearing-box, showing the shaft arranged therein and my improved
thrust-bearing applied.
Figure 2 is a transverse section through the bearing-box on line - of
Fig. 1, showing the thrust-bearing in face view, the course of the lubricating-
duct being indicated in dotted lines.
Fig. 3 is a vertical section of the thrust-bearing, showing the lubricating-
duct therein.
A is a strong two-part metal box-bearing formed with a journal-seat 1, adapted
to receive and hold the end portion of a shaft, and having a strong upwardly-
projecting end piece 2 to resist the pressure of the thrust to which the shaft may
be subjected and through the end piece 2, centrally therein, is let a strong
adjusting-screw 3, provided with a handpiece 4, by which the screw may be
turned and adjusted. On the lower section or part of the bearing-box is fitted
a strong cap 5, the inner end of which fits against the end piece 2 of the lower
section and is formed with a central open-end slot or recess 6, in which fits the
neck or projection on the thrust-bearing.
The cap 5 of the bearing-box is secured in place to the lower part by means
of any proper fastenings, as by the usual bolts, as shown.
B is the thrust-bearing composed of a substantial disk of suitable metal formed
with a vertically-projecting neck-piece 7, adapted to set within the recess or
slot 6 in the cap of the bearing-box to hold the disk against movement and
position by the action of the shaft. In the thrust-hearing B is formed a
lubricating-duct 8, leading through the neck-piece 7 and opening at the center
of the disk, as shown in Fig. 3 and suitably mounted on the neck-piece 7 in

page_text: connection with the lubricating-duct 8 may be an oil-cup 9, by which the
lubricant is supplied in a well-known manner.
It will readily be perceived that my improved thrust-bearing is applicable
to horizontally-disposed shafts having an end thrust, and also to vertically-
arranged shafts, in the latter instance the lubricating-cup being arranged in
vertical position to convey the lubricant to the shaft.
My invention is particularly applicable to the shafts in vertical corn-mills,
crushers, &c., wherein the shafts have an end-thrust pressure.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I do declare that what I
claim is
1. A thrust-bearing for shafts comprising a bearing-box composed of two
separable sections, the lower part or half being formed with a vertical end
piece to resist the thrust of a shaft and the cap of the box being formed with
an open-end slot or recess, and a thrust bearing disk, in the end of the box,
formed with a neck-piece adapted to fit in the recess of the cap to prevent the
disk from turning, and an oil-duct leading through the said neck-piece into the
disk and opening centrally therefrom substantially as specified.
2. A thrust-bearing for shafts comprising a bearing-box comprised of two
separable sections or parts, the lower part or half formed with a vertical and
piece to resist the thrust of a shaft, and the cap of the box formed with an open-
end slot or recess, a thrust-bearing disk in the end of the box formed with a
neck-riece to set in the recess of the cap to prevent the disk from turning and
an oil-duct leading through the said neck-piece into the disk and opening
centrally, therefrom, and an adjusting-screw let through the end piece of the
bearing-box to adjust the thrust-bearing, substantially as described.
Dated this 18th day of February 1899.
