PROVISIONAL SPECIFICATION.
An Improved Moveable Reflector Lamp.
I, THOMAS BASTIN of No. 2 Eustace Terrace, Wiverton Road, Beckenham in
the County of Kent, Secretary do hereby declare the nature of this invention to
be as follows:
To give an universal movement to a reflector and its contained lamp I support
1
the same in its bearings on the top of a moveable standard of convenient height by
means of a flexible band to which a counterpoise is attached, the said band passing
over a horizontal cross-head which is fitted with suitable pulleys and pivoted>>
centrally so as to revolve easily-the pulleys allowing for the up and down motion
of the whole. The reflector of any size and suitable material is balanced to revolve
on two pins between the ends of a bended arm which arm is attached centrally to
a horizontal bar which passes through and turns conveniently in the sleeve bearing
to which the band connecting the counterpoise is fastened as before mentioned.
The sleeve is furnished with clips to form guides in up and down movement on the
standard and the revolving horizontal bar is weighted at the end opposite to the
bended arms to balance the reflector in the sleeve bearing.
Dated this 23rd day of November 1892.

COMPLETE SPECIFICATION.
An Improved Moveable Reflector Lamp.
I, THOMAS BASTIN, of 2 Eustace Terrace Wiverton Road Sydenham, S.E.
Representative 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 :-
To give an universal movement to a reflector and its contained lamp I support
the same in its bearings on the top of a moveable standard of convenient height by
means of a flexible band to which a counterpoise is attached the said band passing
over a horizontal cross-head which is fitted with suitable pulleys and pivoted
centrally so as to revolve easily, the pulleys allowing for the up and down motion
of the whole.
The reflector, of any size and suitable material, is balanced to revolve on two
pins between the two ends of a bended arm which arm is attached centrally to a
horizontal bar which passes through and turns conveniently in the sleeve-bearing
made to encircle the standard and to which the counterpoise is fastened as before
mentioned. The sleeve is furnished with clips to form guides in moving up and
down the standard, and the revolving horizontal bar is weighted at the end to
balance the reflector in the sleeve bearing.
Referring to the accompanying drawing, which forms part of this Specification,
I have shown two positions of, the reflector and its mechanism under Figs. I & II,
using the same standard S in both positions. The letters of reference in Figs. 1
& II are the same for all parts, but for convenience of reference the letters in
Fig. II. have the figure 2 attached in each case.
The reflector R¹ with its contained electrical lamp, arc or incandescent, connected
at O. and its sub-reflector Q, is balanced by means of pins, adjustable if
necessary, a¹ a fitted with butterfly nuts, in the ends of arm A so as to revolve
freely. The bended arm A is connected to the horizontal bar B which revolves,
except when held by the binding screw T, in the bearings K fixed, as shewn, in the

page_text: support or sleeve L, which is again in its turn fastened to the vertical guide G
which encircles and works freely up and down the standard S. The counterpoise C
attached to B balances, in the said sleeve L, the weight of the arm A. and its
contained reflector and fittings. The reflector, fittings and counterpoise are con-
nected by means of the bearings K, working in the eyed shackle N, to the flexible
band W which passes over pulleys in the horizontal cross-head P, which is made to
revolve centrally, and are counterbalanced, to work vertically guided by G up &
down the standard S, by the weight D.
The standard S is held vertical and rigid by the collars H fixed to the base Z,
and the whole of the apparatus is made to move on the ground line by means of
casters.
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 :-
1. That by the combination of the mechanism as particularly described herein,.
viz., standard, cross-head with pulleys, guide-sleeve, band and counterpoises I am
able to obtain the universal movement of the reflector and its contained lamp.
2. That the reflector may be raised and lowered to the limit of the standard, as
well as being revolved upon it.
.
3. That the whole apparatus is easily moved from place to place, without danger
of oversetting.
Dated this 23rd day of August 1893.
