We, EDWARD WELLS, of Shoreditch, in the County of Middlesex, Iron-
monger, and WILLIAM PRYOR, of Hackney, in the County of Middlesex,
Ironmonger's Assistant, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN RISING OR ADJUSTABLE BRACKETS FOR SUPPORTING SHELVES
AND RODS IN SHOP WINDOWS AND FOR OTHER PURPOSES," to be as follows:-
The said rising or adjustable brackets for supporting shelves and rods in
shop windows and for other purposes, are ordinarily constructed of an arm
jointed to stationary knuckle plates, the angle at which the said jointed
arm is fixed with respect to the said knuckle plates being determined by
a screw.
Our Invention consists in making the said brackets in the manner herein-after
described, whereby the bracket arm is made to fix itself at the angle to which
it has been raised, and when required the said bracket arm can be raised or
lowered into any of the angles contained in a semicircle.
In constructing rising or adjustable brackets, according to our Invention
we make the jointed end of the bracket arm of a circular form, and we make
on the periphery or edge of the said jointed end a series of ratchet teeth.
At the top of the knuckle plate or stationary portion of the bracket a small
pall or click is jointed, the said pall or click being so arranged that when in
its normal position its lower end drops into or engages with the ratchet teeth

page_text: on the jointed end of the bracket arm and fixes the said arm; on lifting the
arm the pall or click works over the said teeth without obstructing the
motion of the arm, but on loosing the said arm the pall or click drops into
the ratchet teeth brought under it, and thus fixes the bracket arm; when it is
wished to lower the bracket arm the projecting end of the pall or click is
pressed so as to liberate its lower end from the ratchet teeth. Having
adjusted the bracket arm the pall or click is permitted to re-engage with the
ratchet teeth and fix the bracket arm in its adjusted position. By raising the
bracket arm or pressing the pall or click from the ratchet teeth, the bracket
arm can be raised or depressed respectively into a vertical or nearly vertical
plane, or into any angle between these positions. By this means the bracket
arm offers no obstruction to the cleaning or arranging of the window in which
the brackets are fixed. Instead of making the ratchet teeth on the periphery
of the end of the bracket arm, as herein-before described, they may be made
on the side or sides of the said end, and a pall or click, or palls or clicks
respectively, may be affixed to one or both of the knuckle plates for the
purpose of engaging with the said teeth. Or instead of either of the foregoing
arrangements ratchet teeth may be made on the stationary portion or knuckle
plates, and the click or pall which engages with the said teeth may be affixed
to the jointed end of the bracket arm.
