*Improvements in and relating to Hanging Brackets for Line
Shafting."
I, CARL DIETRICH, of 245 Bahnhofstrasse, Elsterwerda, in the Empire of Germany.
Mauufacturer. 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 that class of brackets hanging from or attached to beams
or the like and supporting the plumber blocks carrying the power transmission
shafting in use in mills, engineering workshops and the like, and its object is to
provide a hanging arm or bracket which can be attached to the beams without
drilling and thus obviate the weakening of the said beams.
The method of carrying this invention into effect is illustrated in the accompanying
drawing as follows,-
Figure 1 is a side elevation of the improved bracket shown in situ upon an
ordinary rolled girder.
Figure 2 is a side elevation of a second bracket which may be used as a substitute
for the beam to carry the hanging bracket upon.
The hanging bracket as shown at Figure 1 consists of a webbed steel or iron
casting a, having a foot e which bears upon the bottom of the beam c. Upon another
portion of the bracket a, a projection a¹ is formed which when the bracket is in situ
buts against one side of the central web of the rolled girder c. The upper extremity
of the bracket is drilled and provided with one or more hook nosed bolts d which
take over the top flange of the girder c as shown, while the foot e of the bracket is
also drilled and carries one or more bolts h which take into a clamping piece i and
pull the said clamping piece down upon the bottom flange of the girder.
It is evident that a bracket of this kind when pulled into position by screwing up
the bolts d and h, is as secure as if it were bolted to the girder itself because the foot
abutting against the vertical web of the girder in conjunction with the bolts h and d
render the bracket practically integral with the said girder. A further advantage of
this form of bracket is that it can be rapidly adjusted longitudinally upon any
portion of the girder so that additional bearings and shaftings can be put into position
at a moments' notice. The power transmission shafting is carried in suitable bearings
between the jaws of the bracket at b as shown.
When a rolled beam of the class shown is not in use and it is desired to fix the
hanging bracket, a second bracket is used constructed as shown at Figure 2. This
bracket is profiled at one side in a similar manner to the beam which it replaces,
that is to say it has a vertical web c¹ and top and bottom flanges.
The uppermost
portion of these flanges may have stops 7 to suit the bolts d and the remainder of
the bracket is suitably constructed for attachment to any part of the shop beams or
structure.
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,

page_text: of hooked bolts which take over the top flanges of the beams, clamps which take over
the bottom flanges of the beams, and foot abutments which rest upon the vertical
web of the beams, all as a means for attaching the brackets to the girders without
bolting.
2, The improvements in and relating to hanging brackets for line shafting
substantially as and for the purposes herein before described with reference to the
accompanying drawing.
Dated this 17th. day of November 1897.
