Improvements in or relating to Counter Shafts and Hangers
therefor.
We, JOHN FISHER, and WATSON KINNEY, of Bridgetown, Nova Scotia,
Canada, Inventors, 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:-
Our invention relates to a combined shaft-hanger and an idler or dead pulley
support; and it has for its object to provide a hanger of this character which will
equalize the lateral strain of the shaft and the weight of the pulley and provide an
essentially universally-balanced bearing for said shaft.
It has also for its object to construct the bearing boxes in said hanger so that
the same may be employed either as a ceiling or a floor shaft support.
To this end our invention consists in certain novel combinations and peculiar
constructions of parts all of which will be hereinafter fully described in the annexed
Specification, and particularly pointed out in the claims, reference being had to the
accompanying drawings, in which
Figure 1 is a side view, partly in section, of our improved hanger.
Fig. 2 is a cross section, of the same on the line 2 2, Fig. 1.
Fig. 3 is a cross-section on the line 3 3, Fig. 1; and
Fig. 4 is a detail view hereinafter referred to.
In the accompanying drawings, A denotes the drive-shaft, which is supported in
the arm B of the bracket or hanger B, and upon which is keyed the drive-
pulley C.
D indicates the loose or idler pulley, journalled upon a sleeve d, which encircles
the shaft A, and which is adjustably supported in the arm B2 of the bracket in a
manner most clearly shown in Fig. 3 of the drawings. By reference to said figure
it will be seen that we form the lower face of the bearing-box 6 of the arm B²
with a longitudinal opening of sufficient width to permit the shaft and sleeve being
inserted through the same. The sleeve d is adjustably held in said box by means
of the adjusting-screws bb, arranged as shown, which hold the said sleeve in
a true position about the shaft A. The hanger B is provided with a foot portion B³,
which is secured by means of bolts a a and nuts a¹ a¹ to the ceiling, the lower
portions of said arm being bifurcated and formed into lateral arms B' B', as
shown. The arm B' extends somewhat lower than the arm B, and is formed with
a slot 10 in the bottom to admit of the passage of the shaft when the hanger is put
in position.
E denotes a long bearing-box formed of two sections e e', which embrace the
shaft A and support it. By reference to the drawings it will be observed that the
lower section ef is cast with a recess 1 in the bottom at right angles with the shaft,
in. which extend the upper ends of the lower balance-screws 2 2, which pass up
through the horizontal members 6 of the hanger B'.
It will be observed that the bearing-box E is disposed centrally between the
hanger-arms of the hanger, and the screws 22 and 3 3 being arranged in said
rms b, as shown, that the said box has a central horizontal pivot-bearing.
44 denote horizontal adjusting screws, which serve to give the bearing-box the
proper lateral adjustment, such adjustment being permitted after the screws 22
and 3 3 have been adjusted, owing to the screws 22 operating in the recess 1 before
referred to. The sides of the box are curved, as at E, (see Fig. 4,) so as to
pernit the box or shaft binding against the adjusting-screws 4 4 in case of

page_text: movement of said shaft or box. The two screws 3 3, which pass through the top,
also serve to support the box when the hanger is reversed and used as a floor-shaft
support.
The side wings Ę? of the box E are extended over the slot 10 in the hanger, so
that in case the screws 22 become loosened and drop out the box will be caught on
the horizontal arms be 6 of the hanger, thus making the same a safety-hanger.
To take down the shaft, all that would be necessary is to slacken the adjusting-
screws and slip the box end-wise, and the two parts thereof can be readily removed
from the shaft. When the hanger is used as a floor support, all that would be
necessary is to turn the same upside down and fasten the foot portion B³ down to
the floor. It will also be understood that the sleeved and the loose pulley D may
be made, if desired, in two parts, to permit the same being adjusted upon a shaft
already in position.
From the foregoing description, taken in connection with the drawings, the
advantages of my improvement will readily appear.
It will be seen that by
forming the bracket with lateral arms B' B', the arm B³ having a bearing-box for
the loose pulley and the hanger B having a bearing in its opposite arm for the
shaft, that the strain of the shaft on the hanger at one arm is counterbalanced by
the strain and weight of the loose pulley on the other arm of the hanger, and by
arranging the bearing-box for the shaft in the manner described the shaft and the
loose pulley may always be adjusted in true plane with each other.
Our invention is very simple in construction, and can readily be put in operative
position.
Having now particularly described and ascertained the nature of our said inven-
tion. and in what manner the same is to be performed, we declare that what we
claim is :-
1. A shaft-hanger comprising a bracket or hanger B, having bifurcated
arms B1 B2, the arms B2 provided with a bearing-box b, adapted to receive the
loose pulley-supporting sleeve, the arm B', provided with a bearing-box adapted to
receive the shaft, substantially as and for the purpose described.
2. The combination, with the hanger B, provided with bifurcated arms B' B³, a
sleeve d, journalled in the lower end of said arm B³, adapted to support the idler
or loose pulley D of the bearing-box E, formed of two parts ee', centrally
adjustable in the lower ends of the arm B', substantially as and for the purpose
described.
3. The combination, with the hanger-arm B', provided with side arms b
having horizontal members or extensions, of a sleeve-like bearing-box E, formed
of the upper and lower sections e e', the lower section provided with recesses 1,
arranged at right angles to the shaft, screws 2 2, extended up through the
horizontal extensions of the arms b³ ³, entering said recesses 1 and supporting the
bearing-box, substantially as and for the purpose described.
4. The combination, with the arm B', provided with the hanger-arms bb and
horizontal members 66 66, of the bearing-box E, centrally pivoted between snid
hanger-arms, consisting of the two sections e e', formed with the side wings or
extensions E, lapping the members 6, the lower section provided with
recesses 1, arranged at right angles to the shaft, screws held in the members 6º 16,
entering said recesses 1, screws 3, passed down through the arm b and engaging
the top of said box, said screws 2, 3 vertically adjusting said box, and screws 4, 4,
engaging said box at the sides and adjusting same laterally, substantially as and
for the purpose described.
5. A hanger or shaft-support consisting of the bracket or hanger B, having
lateral arms B B³, said arms formed with extensions or boxes adapted to receive
and support the shaft-bearings and the loose-pulley sleeve, said extensions or boxes
provided with longitudinal slots in their lower faces of slightly greater width than
the shaft, substantially as and for the purpose described.

page_text: 6. The combination, with the hanger having lateral arms B¹ B³, a sleeve d,
adjustably secured in the lower end of the arm B³, a loose pulley D, mounted on
said sleeve, of a shaft-bearing pivotally and adjustably supported in the lower end
of the arm B', and means for adjusting said bearing, substantially as shown and
described.
