I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn, in the
County of Middlesex, Civil Engineer do hereby declare the nature of this inven-
tion to be as follows:-
The legs of field casels have hitherto been provided with simple iron points,
which, for the purpose of holding the casels firmly in the ground were inserted
therein. In the case of level or suitably firm ground this answered fairly well, but
in the case of loose, hard, or very uneven ground, or when the easel required to be
tilted in a forward position in order to avoid deleterious reflections of light on the
painting surface, the hold of the iron points in the ground was so slight that a light
pressure or puff of wind would throw down the easel, together with the picture or
the like, placed thereon.
The object of this invention is to remove these drawbacks, and to provide a device
by means of which easels, and the like, may be firmly secured to the ground in any
position irrespective of the nature of the ground.
This is accomplished in the following manner :-
A bolt is movably arranged on a pin attached to the leg of the easel by screwing,
or in any other suitable manner. An adjustable pointed iron pin passes through
this bolt and may be fixed by means of a clamp screw, and which when not in use
is held up against the easel leg by means of a lug on the same and the clamp screw.
In order to fasten the easel leg to the ground the clamp screw is first slackened, and
then the pointed iron pin is drawn out of the lug. The casel is then brought into
the desired position, and the pointed iron pins driven sufficiently deep into the
ground, obliquely to the easel legs, and then the clamp screw is again tightened.
The easel is thus anchored so firmly to the ground that it is in a position to resist
even a great wind pressure, the nature of the ground being immaterial.
For releasing the easel it is only necessary to take hold of the legs of the same
near the ground and the pointed pin may be easily drawn therefrom. Then after
slackening the clamp screws the pointed pins may be pushed through the lugs on
the legs of the casel back again into their non-working position against the casel
leg and there fixed.
Another arrangement is as follows:-
The pointed iron pin is flexibly connected with the pin attached to the leg of
the easel by means of a holt, provided with wing nut. The pointed iron pin
which may also be fixed at any angle by means of the wing nuts and driven into
the ground, is, when not in use, folded up against the leg and there secured by the
wing nuts.
A convenient fastening device may also be employed, in which a sliding socket is
placed over the leg of the casel, and through both a bolt is passed provided with
the adjustable pointed pin at one end, and a winged nut at the other by means of
which the parts are held together.
The pointed iron pin holder of the bolt is, also, movably inserted in the socket,
aforesaid, so that it may be placed at any desired angle, and may be fixed there
by tightening the winged nut aforesaid and pressing the pointed iron against
the slide.

page_text: As regards the anchoring of this device in the ground, and the holding of the
same in its non-working or folded position, the method already described is
employed.
These devices may be either permanently attached to the stand or casel legs and
the like, or be so arranged that if desired they may be easily attached thereto, or
removed therefrom, with very little trouble.

Improved Device for Securing Field Easels, Stands, and the like
in Position.
A communication by EDWARD RICHARD BUTLER, of Ueberlingen, Baden, in the
Empire of Germany, Artist.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
The legs of field easels have hitherto been provided with simple iron points,
which, for the purpose of holding the easels firmly in the ground were inserted
therein. In the case of level or suitably firm ground this answered fairly well, but
in the case of loose, hard, or very uneven ground, or when the easel required to be
tilted in a forward position in order to avoid objectionable reflections of light on
the painting surface, the hold of the iron points in the ground was so slight that a
light pressure or puff of wind would throw down the easel, together with the
picture or the like, placed thereon.
The object of this invention is to remove these drawbacks, and to provide a
device by means of which easels, and the like, may be firmly secured to the ground
in any position irrespective of the nature of the ground.
On the accompanying drawings various forms of construction of this device are
shown.
That shown in Figure 1 in a front view and partial section and
Figure 2 a side view consists of a bolt a which is movably arranged on a pin c
attached to the leg of the easel by screwing, or in any other suitable manner.
An adjustable pointed iron pin d passes through this bolt and may be fixed by
means of a screw e and which when not in use is held up against the easel leg by
means of a lug on the same and the screw e. In order to fasten the easel leg to
the ground, the screw e is first slackened, and then the pointed iron pin d is drawn
out of the lug. The easel is then brought into the desired position, and the
pointed iron pin d driven sufficiently deep into the ground, obliquely to the easel
legs, as shown in Figure 3, and then the clamp screw e is again tightened. The
easel is thus anchored so firmly to the ground that it is in a position to resist even a
great wind pressure, the nature of the ground being immaterial.
For releasing the easel it is only necessary to take hold of the legs of the same
near the bolt a and the pointed pin may be easily drawn out of the ground. Then
after slackening the screw e the pointed pin d may be pushed through the lugs fon
the legs of the easels back again into their non-working position against the easel
leg and there fixed.
C
In the arrangement shown in Figure 4, the pointed iron pin d is jointed to the
pin c attached to the leg of the easel by means of a bolt a provided with wing
nut e'. This pin d which may also be fixed at any angle by means of the wing

against the leg in the manner shown in dotted lines and there secured by the
wing nut el.
Figures 5 and 6 show a horizontal and vertical section respectively of a fastening
device in which a sliding socket is placed over the leg of the casel, and through.
both a bolt a is passed provided with the adjustable pointed pin d at one end, and
a winged nut el at the other by means of which the parts are held together.
The pin holder d' of the bolt a is, also, movably inserted in the socket
it may be placed at any desired angle, and may be fixed there by tightening the
winged nut eas thereby the pin d is pressed against the slide.
so that.
As regards the anchoring of this device in the ground, and the holding of the
samme in its non-working or folded position, the method already described is.
employed.
These devices may be either permanently attached to the stand or casel legs and
the like, or be so arranged that if desired they may be easily attached thereto, or
removed therefrom, with very little trouble.
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, 1 declare that what I claim, is:
A device for fastening field easel legs, stands or the like, characterised by the
arrangement of a movable peg or pin d attached to the easel legs by means of a
bolt or the like, which peg is to be driven into the ground in order to secure the
stand, substantially as hereinbefore described and shown.
