Hanger for Shafting.
I, JOHN OTTO DONNER, of 11 West 38th Street, in the City, County and State
of Now York, United States of America, Engineer, do hereby declare the nature
of this said 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 the construction of a readily adjustable shaft, hanger
composed in part of iron castings and pairs of wrought iron or steel tubes so
organized that the same castings may be used with pairs of tubes of different
lengths in the construction of hangers of different lengths.
The accompanying drawings of a shaft-hanger containing the invention are
as follows, viz. :-
Fig. 1 is a front elevation of the hanger showing the end of the journal box.
Fig. 2 is a side elevation partly in vertical section taken through the plane
indicated by the dotted line a, a, on Fig. 1.
Fig. 3 is a transverse section taken through the plane indicated by the dotted
y, y, on Fig. 1.

Fig. 4 is a transverse section taken through the plane indicated by the dotted
2, 2, on Fig. 1.

Fig. 5 illustrates a modification of the method of staying the journal box, and
consists of an end view of the journal box and an elevation partly in section of a
portion of the bridge G.
Fig. 6 is a section taken through the plane indicated by the dotted line, x',
on Fig. 5.
The drawings represent a hanger composed of two convergent tubular iron or
steel legs, A, a, the nearer ends A, a¹, of which are screwed into a cast iron yoke B,
the central portion of which is perforated: and tapped to receive the journal box
stay-bolt C, provided with the jam nut C' for fixing the stay-bolt in the position in
which it may have been adjusted.
1-
The more distant ends A', a', of the legs A,,a,,aré respectively screwed into
cast iron brackets D, d, provided with slotted holes D, d, for the reception of the
bolts D, d, by which the hanger is secured to the surface of the beain E, or other
object to which it is to he attached::
***
The end portions B', ', of the yoke, in addition to each being tapped to receive
the screw threaded ends A, a of the legs) A, a; are cast around the heads F, f, of
the parallel screw bolts F, f, which are respectively provided with the pairs of
nuts F, F, f, which are intended to fix the position of, and to secure in place,
the bridge'G, through the perforated opposite ends of which the screw bolts Ff,
loosely extend.

The journal box may be made in one piece for use where opportunity is afforded
for slipping it over the end of the shaft for which it is to afford a bearing, or
otherwise it may be made of two half boxes H, h, as illustrated in the drawings.
The half box, HI, is provided upon its exterior surface with the boss H¹, in
which there is formed a cavity H2 for engaging the end C of the journal box
stay-boli C.
For staying the journal box both lengthwise and crosswise two methods are
illustrated in the drawings.
In that shown in Figures 1 and 2, the middle portion of the half box.h is provided
with the transverse rib ', the surface of which is slightly curved in cross section
and bears upon the adjacent surface of the bridge G, between the lugs g, gl, which
The
serve as guides for holding the box midway between the bolts F, f.

page_text: half box is also provided with the exterior lips h³, h³, which lap over the
opposite sides of the bridge G, and serve to prevent any longitudinal movement
of the box.
In the modification illustrated in Figures 5 and 6, the half box h is provided
with two lugs h, h³, which are adapted to be seated upon the bottoms of the
cavities g, g³, formed in the top of the bridge G.
It will of course be understood that if a journal box in one piece is used. then,
in addition to being provided on one side with the boss H' having formed in it
a cavity H', the box will be provided upon its opposite side either with the
transverse rib, or with the two lugs ', . By either of these forms of con-
struction the journal box as a whole is stayed both lengthwise and crosswise in
addition to being clamped against the bridge G by the stay-bolt C.
Lateral adjustment of the hanger is permitted by the employment of the
slotted holes D', d, for the reception of the fastening bolts D, ď².
The yoke B, the bridge G, and the pair of screw-bolts F, in their combined
relation constitute the journal box chamber, within which moderate variations of
the position of the journal box are effected by appropriately adjusting the
stay-bolt C, and varying the positions of the pairs of nuts F, F, and 1,³, so as
to vary, as may be desired, the distance of the bridge G from the yoke B.
'
For a journal box of given size, the same castings may be used to form a
hanger of any length, by using longer or shorter tubes for the legs A, a.
By such
a construction for the hanger, it becomes unnecessary to carry in hand a large stook
of langer frames of different lengths; but the castings alone may be carried in
stock and bangers of any length inay be promptly supplied, by cutting the tubes
for the legs of the required length with threads upon their ends, and screwing them
into the castings. A hanger thus constructed is both light and strong, and is
comparatively inexpensive.
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:
1. The herein described shaft hanger consisting of the combination of brackets
adapted for attachment to suitable supports, a journal box chamber substantially
as described and pendent legs located between and separably uniting the brackets
and the journal box chamber, as set forth.
2. In a shaft hanger, the combination, as herein described, of the convergent
tubular legs A, a, the yoke B provided with the journal box stay-bolt C, the
brackets D, d, the parallel screw-bolts F, provided with the pairs of nuts F, F3,
and f, the bridge G, and a journal box confined between the yoke B and the
bridge G, and between the adjacent portions of the screw-bolts F',', as and for
the purpose set forth.
3. The combination, as herein described, of the bridge G provided with the
lugs g.and y', and the adjacent part of the journal box provided with the rib /¹
and the lips and h³.
