Improvements in Clamps for Securing the Bars of Display Racks
for Shop Windows and other Places.
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:-
:-
This invention relates to clamps for securing the bars of display racks for use
in exhibiting goods of various kinds in shop windows and other places.
The improved clamp consists of a block preferably of cast metal, and formed
The face
with a central perforation, through which a clamping screw eye, passes.
of the clamp block is recessed to receive the eye, and said face has one or more
grooves, intersecting said recess, to accommodate a bar, which passes through the
eye of the clamping screw eye. The opposite side of the clamp block has a
groove, for the accommodation of a bar, which may thus fit in said groove, and be
retained in the same by a clamping plate, which may bear against the bar and
against a raised fulcrum, upon the clamp block, and which is clamped against said
parts by means of a thumb nut, upon the threaded shank of the screw eye, having
a reduced neck, formed with a collar, and which fits in the hole of the clamping
plate and thus retains the latter in its proper position. The form of clamp above
described has one groove only, in the side where the clamping eye projects, so
that the bars will be connected at one predetermined angle, in the present case, at
a right angle.
Another form of clamp has a number of grooves, which thus admit of the
bars being adjusted at varying angles to each other. The clamp is principally
interded for connecting the bars of display. racks upon which wares of various
kinds are exhibited in shop windows, and the clamp admits of an almost infinite
amount of variations in the adjustment of the bars composing the rack, especially
the form of clamp having several grooves across its face.
The clamping plate is retained upon the neck of the thumb nut by means of
the collar, and will thus be moved into and from its clamping position by the
thumb nut, which, however, is free to turn without turning the plate, as its neck is
swivelled in the hole of the plate.
Other modes of applying the principle of the invention may be employed for
that herein explained. Change may therefore be made as regards the mechanism
thus disclosed, provided the principles of construction herein set forth are
employed.

Improvements in Clamps for Securing the Bars of Display Racks
for Shop Windows and other Places.
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 :-
This invention relates to clamps for securing the bars of display racks for use in
exhibiting goods of various kinds in shop windows and other places.
In the accompanying drawing I have shown how the invention may be carried
into practice.
Figure I represents a side view of one form of my improved clamp ;
Figure II a view of the opposite side ;
Figure III is a section on the line III-III, of Figure I; and
Figures IV and V, are perspective views from opposite sides of another form
of clamp.
The improved clamp consists of a block A, preferably of cast metal, and formed
with a central perforation, a through which a clamping screw eye, B, passes.
The face of the clamp block is recessed, as at a' to receive the eye, and said face
has one or more grooves a², intersecting said recess, to accommodate a bar, C,
which passes through the eye of the clamping screw. The opposite side of the
clamp block has a groove a³, for the accominodation of a bar D, which may thus
fit in said groove, and be retained in the same by a clamping plate B', which may
bear against the bar and against a raised fulcrum a, upon the clamp block, and
which is clamped against said parts by means of a thumb nut B2, upon the threaded
shank of the screw eye, having a reduced neck b, formed with a collar b', and
which fits in the hole of the clamping plate and thus retains the latter in its proper
position. The form of clamp illustrated in Figures I, 11 and 111, has one groove
only, in the side where the clamping eye projects, so that the hars will be connected
at one predetermined angle,-in the present case, at a right angle. The form of
clamp illustrated in Figures IV and V, has a number of grooves, which thus admit
of the bars being adjusted at varying angles to each other. The clamp is
principally intended for connecting the bars of display racks upon which wares of
various kinds are exhibited in shop windows, and the clamp admits of an almost
infinite amount of variations in the adjustment of the bars composing the rack,
especially the form of clamp having several grooves across its face.
The clamping plate is retained upon the neck of the thumb nut by means of
the collar, and will thus be moved into and from its clamping position by the thumb
nut, which, however, is free to turn without turning the plate as its neck is swivelled
in the hole of the plate.
The details of the device may be modified in various ways without departing
from the principle of the invention.
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 correspondent, I declare that what I claim is :-
1. The combination with frame bars of a corner block having bar grooves on its
opposite faces, and a clamp for securing the bars to the corner block, substantially
as set forth.
2. The combination with a clamping block having bar grooves on its opposite
faces, of a clamping screw passed through the block and having a clamping eye
at one face of the block and a clamping plate at the other face, substantially as
set forth.

page_text: 3. The combination with a clamping block having bar grooves on its opposite
faces and a recess in one face intersected by a bar groove, of a clamping screw eye
baving its eye in said recess and inserted through the block, a clamping plate upon
the shank of the screw eye, and a thumb nut bearing against said plate. substantially
as set forth.
4. The combination with a clamping block having bar grooves on its opposite
faces, of a clamping screw eye passed through the block and having its eye
registering with the bar groove on one face, a thumb nut upon said screw, and
a clamping plate projecting over the bar groove on the other face of the block and
having the thumb nut swivelled in it, substantially as set forth.
5. The combination of a clamping block having a har groove on its face, a
clamping plate projecting over said groove, and a clamping screw for said plate,
substantially as set forth.
6. The combination of a clamping block having a bar groove on its face, a
screw projecting from said face, a clamping plate movable upon said screw and
projecting over the groove, and a thumb nut upon the screw and bearing against
the plate, substantially as set forth.
