Improvements in Easels.
We, JAMES WILLIAM BROWN, of the Firm of Pearson and Brown, Weaste,
Manchester, in the County of Lancaster, Church and School Furniture Manu-
facturers, and HENRY BAGULEY, of Fairfield, Manchester aforesaid, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to either school or artists' easels and is designed to pro-
vide for the easy adjustment of the board, picture or frame thereon without the
use of the pins or pegs such as are at present in use.
It consists essentially in the combination with the easel of a vertically sliding
bar supported on a ratchet rack or the like affixed to the uprights of the easel so
that it can be readily adjusted to any desired height.
In carrying out the invention we provide a movable cross bar with two brackets,
lugs or arms attached each carrying a pin or stud or the like to traverse a groove
or slot and upon which or about which as a centre the bar can be moved.
To the uprights at either side we affix a ratchet or toothed bar with a longi-
tudinal groove at one side into which the aforesaid pins are fitted and in which
they are capable of sliding up and down. The position of the pin and groove is
such that any weight put upon the adjustable bar forces it backward and there-
fore holds it firmly in position upon whichever tooth of the ratchet or rack it is
placed.
By drawing the bar forward it is released from the ratchet and may be raised
or lowered and adjusted as may be required.

We, JAMES WILLIAM BROWN, of the Firm of Pearson and Brown, Weaste,
Manchester, in the County of Lancaster, Church and School Furniture Manu-
facturers, and HENRY BAGULEY, of Fairfield, Manchester, aforesaid, Mechanical
Engineer, 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 easels either for school or artist's use and is designed
to provide for the easy adjustment of the height of a black-board, picture frame

page_text: or other article placed thereon without the use of the pins or pegs such as are
at present in use.
It consists essentially in the combination with the easel of a horizontal bar
capable of sliding vertically supported on a ratchet rack or the like affixed to
the uprights of the easel so that it can be readily adjusted to any desired height.
The invention will be fully described with reference to the accompanying
drawings;
Fig. 1. Front elevation.
Fig. 2. Side elevation (partly in section).
Fig. 3. Enlarged detail.
(Front view.)
Fig. 4. Side elevation of Fig. 3.
Fig. 5. Sectional plan on line y Figs. 3 and 4.
The easel comprising the front frame A and the back or supporting frame B is
constructed in the ordinary way the frames being connected by the hinge C.
In front of the frame A is fitted a movable cross bar D provided with two
brackets E of metal or other material. To each bracket is secured a pin or
pivot e upon which the cross bar can swivel or turn when drawn forward at the
lower edge. The pin or pivot e of each bracket is pivoted to a slide F or the
pivot itself traverses a groove or between guides.
To the uprights of the frame A preferably by the pieces a are attached two
upright rack or toothed bars G with the teeth g projecting towards the front
and a longitudinal groove g¹ in the inner side. The grooves serve as guides for
the slides F to traverse from top to bottom of the racks.
The teeth g of the rack or bar G are so placed as to engage the lower edge
of the cross bar D or the brackets E thereon when any weight is placed thereon
and prevents downward movement. The cross bar D can be raised or slid upwards
to any desired position and by raising it slightly and drawing it forward to clear
the teeth it may be lowered to any position.
The bar D and any board or picture thereon can thus be adjusted to any height
as may be required."
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed we declare that what wo
claim is:
1. An easel constructed with a vertically sliding cross bar to support a board
picture or frame thereon, racks to maintain the cross bar at the desired height
and provided with grooves in which slides or pins attached to the cross bar slide
up and down substantially as described.
2. An easel having the several parts constructed and arranged in combination
substantially as and for the purposes described.
