PROVIDIONAL SPECIFICATION.
Improvements in Automatic Advertising Machines.
We, THOMAS EDWIN WOOLSTONE, JAMES CARVELL WOOLSTONE, Advertising
Experts, and FREDERICK WILLIAM WOOLSTONE, Engineer, all of 28, Faulkner
Street, Manchester, in the County of Lancaster, do hereby declare the nature of
our said invention to be as follows:-
These improvements refer chiefly to the invention forming the subject of Letters
Patent No. 22082 dated 27th September 1897, and have for their object to effect
the intermittent rotation of the disc or frame carrying the transparencies in a
more positive and reliable manner, to dispense with the need of weights to balance
the said frame when only partly filled or otherwise out of balance, and at the
same time dispense with all weights and cords and escape "-mechanism, which
are liable to get out of order and interfere with the portability of the machine.
A further object is to provide means for the better regulation of the speed of the
machine, also to provide readier means for the adjustment of the transparency
holders on the frame for focusing and alignment purposes, and, for enabling the
transparencies to pass into, and out of, line with the "objective" without such
movement being observable on the screen,-to provide means for obstructing the
line of projection, and, by the use of two or more sets of transparencies, to allow,
for dissolving views or other effects.

In accordance with our said improvements, we substitute for the notched disc
and pallet mechanism described in the specification of the said former patent, an
arrangement of star" wheel, i.e., a wheel or disc having a series of curved
facits with a slot or opening at the junction of the several facits with which a
smaller disc or pinion, having a single tooth, engages under the impulses of any
suitable form of motor, but preferably an electric motor.
The said "star" wheel, to which the frame for carrying the transparencies is
connected, has the same number of facits as there are pictures or advertisements,
and the curvature of each facit corresponds with that of the disc or pinion, hence
when the disc is in motion the star" wheel is rotated one facit for each
revolution, and thus the required pause and intermittent motion is obtained, with
the frame held in an absolutely true position for each transparency.
To vary the rate of movement the disc may have two or more teeth, or the
speed of the motor may be varied, or in case the disc is driven through intermediate
gearing the sizes or number of the wheels may be varied.
The several holders for securing or carrying the transparencies on the frame
are each mounted on a base adapted to tilt, or move vertically or laterally under
the action of a screw and nut, or set of screws.
For effecting the traverse of the pictures without its being apparent on the
screen, we provide a rotary shutter or blind, "timed" to move across the line of
projection whilst the frame is in motion, and remain stationary, or have a slow
movement, during the period of display.
For dissolving views or like effects we employ two or more frames driven in

page_text: the same or a similar manner, at the same or different speed, and adapted to carry
transparencies of various kinds.
Dated this 22nd day of August 1898.

COMPLETE SPECIFICATION.
Improvements in Automatic Advertising Machines.
We, THOMAS EDWIN WOOLSTONE, JAMES, CARVEL WOOLSTONE, Advertising
Experts, and FREDERICK WILLIAM WOOLSTONE, Engineer, all of 28, Faulkner
Street, Manchester, in the County of Lancaster, 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:-.
These improvements refer chiefly to the invention forming the subject of Letters
Patent No. 22082 dated 27th September 1897 and have for their object to effect
the intermittent rotation of the disc or frame carrying the transparencies in a
more positive and reliable manner, to dispense with the need of weights to balance
the said frame when only partly filled or otherwise out of balance, and at the
same time dispense with all weights and cords and escape mechanism, which
are liable to get out of order and interfere with the portability of the machine.
A further object is to provide means for the better regulation of the speed of the
machine, also to provide readier means for the adjustment of the transparency
holders on the frame for focusing and alignment purposes, and, for enabling the
transparencies to pass into, and out of, line with the "objective" without undue
vibration.
In accordance with our said improvements, we substitute for the notched disc
and pallet mechanism described in the specification of the said former patent, an
arrangement of disc wheels, one having a series of curved facits and the other
plain and adapted to fit any one of the facits, and with a tooth (or notch) adapted
on rotation to engage with recesses (or edges) in the other disc at the junction
of the facits, and at each revolution rotate the other disc. The movement is by
preference obtained by a small electric motor. The facits on the disc wheel
correspond in number to the number of frames for holding the transparencies
herein at each rotation of the smaller disc, the facit wheel and frame are rotated
one facit, and the transparencies brought intermittently in line with the line of
projection. To vary the rate of movement the smaller disc may have two or more
teeth (or notches).
The holders for receiving and carrying transparencies are each mounted on a
base, adapted to tilt, or move vertically or laterally under the action of a screw
and nut.
To make our improvements clear we have hereunto annexed a sheet of drawings
in which
Fig. 1 represents a front view (partly broken away) and Fig. 2 a side elevation
of the advertising apparatus with our improvements applied thereto.
Fig. represents a part plan and Fig. 4 a detail.
To the shaft (A) which drives the frame (B) carrying the transparencies (C)
or to an intermediate shaft gearing with it, I connect a disc wheel (D) having a

page_text: series of curved facits (E) corresponding in number to the number of holders (F).
Alongside such disc and of the same curvature as the facits (E) I arrange a
further disc (G) having a small tooth or by preference a notch (H). The shaft (I)
upon which disc (G) is mounted is driven continuously through speed reducing
gear (J) by a small electric motor (K).
No motion is imparted to the disc wheel (D) until the notch (H) in disc (G)
comes opposite one of the bisecting edges (L) of the disc (D), which then engages
the said edge, and rotates the disc (D) to an extent equal to one of the facits and
continuing to revolve then disengages such edge and by contact of the curved
edges holds the disc (D) stationary until the notch comes round again and engages
with the next bisecting edge, and so on continuously for each facit.
In such way we get a positive and accurate movement of the transparencies
into and out of line with the projecting lenses and with great steadiness of action.
By increasing the speed of the motor, altering the value of the gear wheels (J),
or forming the disc (G) with two or more notches the speed of the frame, or
periods of rest, may be varied.
For enabling the holders (F) to be effectively adjusted for the proper focusing
of the transparencies we provide each holder with a base (F) having a slot (F2),
and by the adjustment of a screw and nut (13) the holder can be adjusted
vertically, laterally and diagonally.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1 In automatic advertising machines, the use in combination of a disc wheel
with curved facits, and another disc wheel adapted to engage any one of the said
facits and with a notch or tooth (or notches and teeth) adapted under rotation of
the disc to advance the facit disc intermittently, as and for the purposes set forth.
2: In automatic advertising machines, the combination and arrangement of
parts, substantially as herein set forth and illustrated on the accompanying
drawings.
