GEORGE R. COOKRUM, OF MINERAL WELLS, TEXAS.
BRACKET.Specification of Letters Patent.
Patented April 27, 1909.
Application filed June 20, 1908. Serial No. 439,620.
To all whom it may concern:
Be it known that I, GEoRGE IR. CoCKRl.WM,
citizen of the United States, residing at Miii-
eral Wells, in the county of Palo Pinto an(l
State of Texas, have invented certain new
and useful Improvements in Brackets, of
which the following is a specification.
The present invention relates to improve-
ments in brackets, and more particularly to
1 a device of this character embodying a novel
construction whereby a shelf may be sup-
ported by means of a single bracket, thereby
eliminating the additional expense and labor
incident to procuring and mounting two
15 brackets in position.
The invention further contemplates a shelf
bracket which is extremely simple and inex-
pensive in its construction and will hold the
shelf rigidly in a horizontal position.
20 For a full understanding of the invention
and the merits thereof and also to acquire a
knowledge of the details of construction and
the means for effecting the result, reference
is to be had to the following description and
25 accompanying drawings, in which:
Figure 1 is a perspective view of a shelf
bracket embodying the invention. Fig. 2 is
a plan view of the blank from which the ver-
tical standard and lateral arms of the bracket
30 are formed, Fig. 3 is a front elevation of the
diagonal braces.
Corresponding and like parts are referred
to in the following description and indicated
in all the views of the drawings by the same
35 reference characters.
Specifically describing the present embodi-
inent of the invention the numeral 1 desig-
nates the standard which is designed to be
stamped from a single piece of sheet material
to and may be conveniently secured to a wall
or other vertical support by means of screws
or fastening members passing through open-I
ings 2 therein. A pair of lateral arms 3 areI
provided at the upper end of the standard,
45 the said arms being stamped from the same
piece of sheet metal as the standard and ex-
tending upwardly in alinement therewith
previous to being bent into position. In
forming the bracket the two lateral arms 3
50 are bent downwardly at right angles to the
standard and that portion of the standard at
the juncture of the two arms is deflected out-
wardly to provide a V-shaped rib 4. One of
the arms 3 is located upon each side of this
55 V-shaped rib and as will be readily apparentfrom 1 the drwi.\V lg this rib serves to elect
the arms and throw tiem into a positi n at.
approximately rightt angles. to each other.
It will tius be apparent that in the finished
bracket the two lateral arms 3 which are de- c,
signed to support the shell are disposed at
substantially right angles to each other and
also to the standard 1.
Each of the shelf supporting arms 3 has a.
longitudinal rib 3" stamped therefrom for l'
reinforcing andi stilkeing the sane and the
said arms are providd (Iwith openings 5 for
receiving fastening members by means of
which they are secured to the shelf. Atten-
tion may also be directed to the fact that the 7)
standard 1 is itself provided with stiffening
ribs 1L similar to those upon the lateral arms.
A diagonal brace 6 is provided for each of
the shelf supporting arms 3 and the two
diagonal braces are preferably integral with 7;
each other so as to be stamped from a single
piece of sheet material and are formed with
the stiffening ribs 6. At their lower ends
the diagonal braces are secured to the
standard by any suible means while a~t 8:)
their upper ends they are secured to the re-
spective lateral arms 3.
Wihen the bracket is in position the stand-
ard 1 is secured to a vertical support while
the two diverging lateral arms 3 project out- 8r
wardly in a horizontal position and are
secured to the bottom of a shelf.
Attention is directed to the fact that with
the construction embodied in the present
invention a shelf may be rigidly held in a 90
horizontal position by means of but a single
bracket, such a construction having the ad-
vantage of obviating the additional expense
and labor which would be incident to form-
ing? two separate brackets and mounting 95
them in position in the usual manner.
Having thus described the invention,
what is claimed as new is:
1. In a shelf bracket, the combination of a
standard, a pair of lateral arms projecting 10
from the upper end of the standard and dis-
posed at substantially right angles to each
other and also to the standard, and diagonal
braces for the lateral arms.
2. In a shell 1)bracket, the combination of a 105
standard, a pair of lateral arms integral with
the standard at the upper end thereof, the
said arms being disposed. at substantially
right angles to each other and to the stand-
ard, and a pair of integral braces secured at 110No. 919,421.
