Improvements in Girder Clamps and Hangers for Supporting Pipes,
Electric Conductors, and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:--
My invention consists of certain improvements in girder clamps and hangers, as
will be hereinafter set forth.
The said invention comprises clamps or jaws adapted to embrace the flange of
the girder or beam. Passing through the lower end of one of the clamps is a
square part of a threaded bolt, which passes through an opening in a head, and is
supported therein, the said bolt also passing freely through the other clamp, and is
provided with nuts, which are adapted to jam or tighten against opposite sides of
the said clamp, so that the clamp may be adjusted on the said bolt.
As the one clamp is sustained on the square or angular part of the bolt, it is
prevented from rotating on said bolt, a matter of importance in primarily locating
said clamp on the girder or beam.
Depending from the beforementioned head is a partly screw-threaded rod,
supporting a pair of arms, on which may be placed or seated water, gas, or other
pipes, electric conductors, wires, or the like, the said arms being vertically adjustable
on said rod, and being provided with bolts for retaining the arms in their adjusted
vertical position.
In the said head is provided an opening, which extends at right angles to another
opening and may have a bolt passed therethrough when so desired.
The lower arm permits a chain or girdle to be suspended therefrom for supporting
a pipe or the like thereon.
The vertical opening in the head has two diameters, so that rods of different
thicknesses may be used if desired.
The said head may be formed with a series of vertical openings for receiving a
number of rods when so desired. In the arms are formed openings with bosses for
receiving and firmly sustaining wires or the like therein.
Dated this 8th day of January 1894.

Improvements in Girder Clamps and Hangers for Supporting Pipes,
Electric Conductors, and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 consists of certain improvements in girder clamps and hangers, as
will be hereinafter set forth.

page_text: In the accompanying drawings
Figure 1 represents a perspective view of a girder clamp and hanger embodying
iny invention.
Figure 2 represents a vertical section of a portion of the same on an enlarged
scale.
Figure 3 represents a vertical section of a head embodying my invention.
Figure 4 is a vertical section taken on the index x, x of Figure 2.
Figure 5 represents a perspective view of a modified form of girder clamp and
hanger embodying my invention.
Figure 6 represents a partial side elevation and partial vertical section of a
detached portion thereof.
Figure 7 represents a side elevation of another part of my invention and
Figure 8 is a plan view thereof.
Similar letters of reference indicate corresponding parts in the several figures
of the drawings.
A designates clamps or jaws adapted to embrace the flange of the girder or
beam B. Passing through the lower end of one of the clamps is a square part C¹
of a threaded bolt C, which passes through an opening C³ in a head D, and is
supported therein, the said bolt also passing freely through the other clamp, and is
provided with nuts E, which are adapted to jam or tighter against opposite sides
of the said clamp, so that the clamp may be adjusted on the said bolt.
As the one clamp is sustained on the square or angular part of the bolt C, it is
prevented from rotating on said bolt, a matter of importance in primarily locating
said clamp on the girder or beam.
Depending from the beforementioned head D is a partly screw-threaded rod F
supporting any desired number of arms G or G₁ on which may be placed or seated
water, gas, or other pipes, electric conductors, wires or the like, the said arms
being vertically adjustable on said rod, and being provided with bolts H for
retaining the arms in their adjusted vertical position.
In the said head D is provided an opening J, which extends at right angles to
another opening (and may have a bolt passed therethrough when desired.
The lower arm G¹ permits a chain or girdle K to be suspended therefrom for
supporting a pipe or the like thereon.
The vertical opening in the head D has two diameters as at L, so that rods of
different thicknesses may be used if desired.
As shown in Figure 3 the head is formed with a series of vertical openings
for receiving number of rods such as F when so desired. In the armis G, G¹
are formed openings with bosses M for receiving and firmly sustaining wires or the
like therein.
In order to prevent lateral motion of the head D, the bar or bolt C is formed,
as shown in Figures 5 and 6 with notches or grooves J¹ adapted to receive a tooth
or projection K¹ on the upper wall of the opening in said head, it being noticed
that said bar is secured to one clamp A and passes freely through the other clamp,
the latter having a set screw G' which is adapted to enter either of the openings Hi
in the bar C, it being evident that when the rod F is adjusted as to lateral
direction, it readily retains its place and the clamps firmly embrace the beam or
the flange thereof.
The arms G¹ may be made cross-shaped as shown in Figures 5, 7 and 8, for the
employment of at least two sets of chains K, and the support of pipes or the like
at an angle to each other.
The hanger rod F may be screwed to the beam or ceiling F¹ as shown in dotted
lines in Figure 7.
As the pipes or the like supported on the arms may expand and contract, and as
it is desirable to provide for the movement of the former in their application to
and removal from the arms, I employ rollers P which are mounted on said arms,
the effect of which is evident.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1st. Girder clamps having a tightening and adjusting bolt connected therewith,
and an arm-supporting device on said bolt, these parts being combined substantially
as described.
2nd. Girder clamps in combination with a bolt with a nut connecting the same,
and an arm-supporting device on said bolt, substantially as described.
3rd. Girder clamps having a bolt adjustably connecting the same, and an
arm-supporting head on said bolt, the latter having a squared part, and one of said
clamps having a squared opening to receive said part and prevent rotating of said
clamps, substantially as described.
4th. Girder clamps having a bolt adjustably connecting the same, and a
supporting head on said bolt, said head having angularly-arranged openings, each
adapted for the passage of a bolt, substantially as described.
5th. In a girder clamp and hanger, a supporting head having a series of vertical
openings, substantially as described.
6th. In a girder clamp, a supporting head having an opening of different
diameters.
7th. In a girder clamp, a rod with a supporting arm or arms thereon, and openings
in said arm or arms, substantially as described.
8th. In a girder clamp, the supporting arm or arms having openings therein, and
bosses for said openings substantially as described.
9th. In a girder clamp, a supporting arm and a chain or girdle thereon,
substantially as described.
10th. Girder clamps, a bar attached to one clamp and freely passing through
the other clamp, and a set screw connected with the latter and adapted to engage
with said bar, the parts being combined substantially as described.
11th. Girder clamps having a bar provided with notches and a head receiving
said bar in an opening therein, and formed with a tooth in said opening adapted to
enter either of said notches, said parts being combined substantially as described.
12th. A girder clamp hanger, and an arm thereon, in combination with a roller
mounted on said arm, substantially as described.
