Improvements in Hangers for Shafting.
We, BART LOBEE, of 618 Main Street, Machinist, GEORGE DUCHSCHERER,
of 314 Norwood Avenue, General Contractor, and FRANK WESLEY CARTER, of
854 Fargo Avenue, General Contractor, all of Buffalo, State of New York, in
the United States of America, 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 relates to improvements in hangers for shafting, of the ball
bearing type; the object being to secure a more efficient bearing, capable of
adjustment in any desired direction, to adjust the raceways so as to compensate for
wear, to construct the raceways in such a manner, that the bearing or wearing
faces can be readily chilled and ground or smoothened, and also in certain details
of construction, as will hereafter more fully appear, and be set forth in the
claims.
While the invention is shown applied to a hanger for shafting, I do not wish to
be understood as restricting myself to that particular class of bearings.
In the accompanying drawings,-
Figure 1 represents a front elevation of the hanger.
Figure 2 is a vertical longitudinal section of the hanger, on line u―u, Figure 3.
Figure 3 is a transverse section, on line v-v, Figure 1.
Figure 4 is a vertical cross section on line w, w Figure 3.
Figure 5 is a horizontal section on line -x, Figure 2.
Figure 6 is a vertical cross section, on line y-y, Figure 3.
Figure 7 is a similar section on line 2-2, Figure 3.
Figure 8 is an enlarged section through a portion of the stuffing-box.
Figure 9, is a perspective view of one of the collars adapted to form the
inner-half ball-raceway, and
Figure 10, is an enlarged section through the bearing ring, showing the manner
of forming the outer-half ball-raceway.
Like numerals of reference refer to like parts in the several figures.
The numeral 1, Figures 1 and 2 represents the stationary hanger-frame, adapted
to be secured to any suitable framing, ceiling or floor of a building, by bolts which
pass through holes in the lateral extensions 2, in the usual manner. The lower
part of the hanger-frame is provided with a hollow portion 3 adapted to support
the bearing-frame 4. This bearing frame consists of the central or body portion 5,
an enlarged senii-circular portion 6, Figures 1, 2 and 4 which is provided with
lugs 7 at its lower end, and a shank 8 Figure 9 at its upper end. This shank is
adapted to extend up through the hollow portion 3 of the hanger-frame and is held
in position by the nut 9, and jam-nut 10, which screw onto the outer screw
threaded portion of the said shank.
If the alignment of the shaft should require adjustment on account of the
warping or sinking of beams, as is a common occurrence where hangers are secured
to the ceiling or floor, the adjustment is readily effected by means of the nuts 9, 10,
which may be either loosened or tightened as the case may require.
11 represents the shaft, and 12, 12, Figure 3 collars secured to the shaft, which
latter form the inner separable and adjustable raceway. Each collar is formed
with an enlarged portion 13 and a tapering extension 14 at its outer end provided
[Price 8d.1

page_text: with slits 15, Figures 6, 7 and 9. The inner ends of the collars are chamfered as
at 16 Figures 5 and 9, preferably at an angle of 45 degrees, but any angle or curve
may be used if desired. The chamfered edges together form the inner half
raceway for the balls. The collars are secured to the shaft by means of clamping
sleeves 17 Figures 5, 6 and 7 which are provided with tapering bores, to correspon
to and fit over the tapering extensions 14. When the clamping sleeves are set
over the slitted tapering extensions, they are drawn up onto the latter by means of
screws 18, Figure 3 which pass through the clamping sleeves and into the enlarged
portions 13 of the collars. By this construction the collars are readily scoured to
the shaft by simply tightening the screws 18, which latter force the clamping
sleeves up onto the slitted extensions 14, and contract the latter onto the shaft,
thereby securely fastening the collars to the latter.
The collars forming the inner-half raceway, are adjustable toward each other so
as to compensate for wear; the adjusting being done by means of the adjusting
screws 19, which pass loosely through one of the clamping sleeves and collar 12,
and engage screw threads in the collar 12ª, and the screws 18 which pass loosely
through the clamping sleeves and engage with screw threads in the collars are
loosened, this releases the hold of the split tapering extensions 14 upon the shaft
and allows said collars being shifted toward each other by the adjusting screws 19,
which are then tightened, admitting of a very fine adjustment, after which the
screws 18 are also tightened, thereby securing the collars forming the inner
half-raceway at the desired points on the shaft.
20 Figures 2, 5 and 10 is a bearing ring which is set over or surrounds the
inner-half raceway, the inner side thereof being provided with an annular V-shaped
groove 21, which acts as the outer-half raceway, and is similar in shape to the
inner-half raceway. This bearing ring consists of a centre ring 28 and side.
portions 23 secured to said centre ring by bolts or in any other well known manner.
These side portions are separable and together form the outer-half raceway. By
forming each half-raceway in two separable parts as described, the wearing faces
can be readily chilled and properly prepared for the reception of the balls.
The adjustable collars forming the inner V-shaped half raceway, and the side
portions 23 of the bearing ring, forming the outer V-shaped half raceway, together
form a four cornered or diamond shaped raceway. By this special construction and
shape, the wear is readily taken up at two bearing points, by the adjusting
screws 19, the effect however being on the four points.
The bearing ring, shaft and parts secured thereto, are set into the enlarged
semi-circular portion 6 of the bearing-frame and held therein by the semi-circular
cap 24, Figures 1 and 4, which is provided with lugs 25. The cap is secured to
the semi-circular portion 6, by bolts 26 which pass through the lugs formed on the
latter, and the lugs 25 of the cap.
The bearing ring, shaft and parts secured thereto, are held from movement in
the direction of the length of the shaft by inwardly projecting flanges 27, Figures 2
and 3, which overlap the outer edges of the bearing ring. These flanges project
inwardly from the enlarged semi-circular portion 6 of the bearing frame and from
the cap 24.
28, Figures 1, 2 and 4, represents radially arranged adjusting bolts, passing
through the semi-circular portion 6 of the bearing frame and through the cap 24;
said bolts bear against the outer face of the bearing ring and hold the entire
bearing rigidly in any desired position. 29 are jam nuts for securing the
bearing in place after being adjusted. The bolts 28 are adapted to adjust the
alignment of the shaft in any direction, if it is found that the latter is sprung
slightly.
30 represents the balls, which are situated in the raceway; these balls are
readily inserted by moving one of the collars forming the inner half raceway
along the shaft.
If it is found that there is a transverse strain due to the belt pressure being
exerted more on one side than on the other of the shaft, and wearing the bearing

page_text: ring accordingly, it is only necessary to unscrew the adjusting bolts and turn the
bearing ring in. position so as to present a new or unworn part to the pressure,
when the device is again in perfect condition after tightening the bolts.
In order to secure the device to the shaft, the collars and clamping sleeves are
slipped over the shaft, the bearing ring over the collars, and the balls located in
the raceway; the collars are then adjusted to the balls by means of the adjusting
screws 19, Figure 5, and secured to the shaft by tightening the screws 18, it is then
set into the semi-circular portion 6, and the cap 24 secured to the latter. The
whole forming a simple and efficient bearing adjustable in any direction.
31, Figure 5, represents hoods or oil receptacles secured to opposite sides
of the bearing frame 4 and cap 24, by means of bolts 32, Figure 1. A washer
or packing 33 is set between the bearing frame and the hood to prevent the leakage
of oil.
34, Figure 5 represents stuffing-boxes through which the shaft passes. This
stuffing-box is constructed by chamfering the edge of the hole 35 formed in the
hood and through which the shaft passes, and securing a plate or cap 36 to
the hood. This cap or plate is provided with a hole 37, chamfered similar to the
hole 35 in the hood. These chamfered portions together form a V-shaped groove
in which a leather washer or other packing 39 is secured. The plate or cap 36 is
secured to the hood by means of screws 40, Figures 1 and 3.
If it is found that the packing is worn and the oil leaking through the same, it
is only necessary to tighten the screws 40, thereby wedging the packing against
the shaft, as is readily seen in Figure 8.
These hoods or oil receptacles are filled with oil, and for this purpose each
hood is provided with an oil inlet 41. 42 are oil outlets formed in the lower
side of each hood. The oil is discharged or taken from the outlets 42, and any
sediments or other matter lodging in the hoods can be easily washed or taken
out without separating the various parts of the hanger. 43 are screw plugs by
which the oil inlets and outlets are closed. By this construction. the raceway and
balls are continually working in oil, thereby preventing the heating and wearing of
the parts.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
