PROVISIONAL SPECIFICATION.
Improvements in Means for Raising and Lowering and Securing in
Position Studio Camera Stands and other Objects.
WALTER JAMES BOUGHTON Photographer King Street Thetford Norfolk
do hereby declare the nature of this invention to be as follows:-
My invention a studio camera stand for photographers or others, or any article
required to be raised up & down to be kept in position wherever wanted without
the aid of set screws. My invention consists of two upright standards grooved for
cords, with cross feet, connected by two cross bars, in between the bars is a spindle
with cords connected to raise & lower the platform between the two standards, a
wheel on spindle to raise & lower with wedge arrangement.

COMPLETE SPECIFICATION.
Improvements in Means for Raising and Lowering and Securing in
Position Studio Camera Stands and other Objects.
WALTER JAMES BOUGHTON Builder &c. King Street Thetford Norfolk 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:-
My invention consist in improvements in pedestals or stands, or other objects
requiring to be raised and lowered by a mechanical contrivance. The said pedestal
or stand is shewn on the annexed drawing of which Fig. I is a sectional elevation.
Fig. II a sectional side view and Fig. III a sectional plan.
The aforesaid pedestal or stand being formed of two upright columns or
standards A and B grooved on their inside edges for receiving slides C & D the
said slides which moves freely up or down the said columns A and B attached to
the said slides C and D is a table or platform E having a radiating or tilting
motion. The said table or platform E being raised or lowered by means of two
cords or chains F and G one end of each cord or chain being secured to the
slides C and D and passing upwards over pulleys or rollers H and J fixed at the
top end of the aforesaid columns A. and B then passing down the outside of columns
and under pulleys or rollers K and L on to windlass or reel M. the said windlass or
reel having a spindle or axle N. which is carried in bearings or cross boards P and R.
The said spindle or axle N carrying on one end a handwheel S. on outside of said hand-
wheel S and inserted into spindle or axle N. is a cottar or wedge T the said wedge
or cottar T being the means of adjustment from preventing the aforesaid slides C
and D from falling when raised to any required position. A slot hole is placed in
spindle or axle N a little wider than the greatest width of cottar or wedge T so
as to allow the said cottar to be driven or thrust further into the spindle or
axle N. Friction is caused by the aforesaid handwheel S being forced or thrust
along spindle or axle N. and hard up against outside of the aforementioned cross
board R at the same time, the said spindle or axle N upon which is the windlass or
reel M is drawn outwards towards handwheel S. and the windlass or reel M. is
brought hard up against inside of cross board R, the windlass or reel M and the
handwheel S. so as to prevent the slides C and D from slipping down when raised
to any required position. It will be readily seen that if the handwheel S is turned
in the direction of arrow as shewn on Fig. I the same being fixed on spindle or
r

the cords or chains F and G attached to it will cause the slides C and D to be
raised. To lower the slides all that is required is to revolve the handwheel in
opposite direction to arrow, and the slides will be lowered by their own weight.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. Improvements in pedestals or stands for studio cameras or other objects,
requiring to be raised and lowered by mechanical means by a frame sliding up or
down between two upright standards or columns.
2nd. Means of raising & lowering frame by cords or chains.
3rd. Raising or lowering frame by means of handwheel and windlass.
4th. Method of causing friction between handwheel & windlass by means of
cottar or wedge.
