PROVISIONAL SPECIFICATION
Improved Intermittent Mechanism for, and its Adaptation to,
Advertising Purposes.
I EDWARD DAVIES, of Gravelly Hill, near the City of Birmingham, Managing
Director of Works, do hereby declare the nature of this invention to be as
follows:
--
This invention relates to improvements in mechanism, whereby an intermittent
motion is obtained suitable for advertising purposes, and the combination therewith
of such advertising matter.
Usually a spring motor clock movement is employed or adapted to carry out my
invention, but a weighted or other similar train of wheels may be used having an
escapement action.
For purposes of description, I will assume it as adapted from an ordinary spring
motor clock movement. I select either of the wheel arbors, according to rapidity
of movement required, but generally the second or third time wheel arbor. Upon
this arbor is of course the pinion which is driven by the spring which exerts a
continuous impelling force thereon. In the wheel itself however, I provide inter-
mittent teeth only, that is to say, between each tooth there is a considerable blank
space. These intermittent teeth as they come forward, engage with the pinion of
the succeeding arbor, similarly as would the usual ordinary teeth upon such wheel.
The succeeding part of the train of wheels up to and including the escapement is
of ordinary make. The aforesaid arbor of the intermittent toothed wheel is
extended a convenient length upon the outside of the framework for the purpose
of connection with any desirable or suitable spindle, pulley, wheel or other
device, carrying or driving any movement upon which is carried any advertising
matter.
It will be noticed that as the teeth of the intermittent wheel engage with or are
passing across the pinion of the succeeding arbor, such pinion, and the further
succeeding mechanism act as a check upon it, and therefore it passes but very
slowly, but immediately that the tooth has passed the retaining position of the
pinion, it is free to receive the full force of the spring to suddenly urge it forward
until the next tooth is thrown against the pinion, and thus again checked for a
repeat action.
During its forward sudden flight it therefore has not to drive the subsequent
mechanism, and consequently the full power of the spring may be utilized in
moving whatever mechanism is connected up to the said intermittent wheel arbor.
If desired such an intermittent wheel may be made to act directly at its teeth to
actuate mechanism.
From the said arbor and in combination therewith, I may as before intimated,
drive suitable wheels, cranks, pulleys, or rollers &c., to operate imitation signal
ports, lighthouses, star wheels &c. &c.

Advertising Purposes.
I EDWARD DAVIES, of Gravelly Hill, near the City of Birmingham, Managing
Director of Works, 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 improvements in mechanism whereby an intermittent
motion is obtained, suitable for advertising purposes, and its object is to provide an
improved intermittent motion, wherein the full power of the motor is alternately
and independently utilized to drive the necessary clock work, and also the apparatus
upon which the advertising matter is exhibited.
In order to more particularly describe the nature of this my invention, I have
appended hereunto an illustrated sheet of drawings, upon which are figures and
numbers of reference, similar numbers referring throughout the several views to
the same thing or part, and in which:
!
Fig. 1, is an inverted plan view of my invention, with the front plate of frame
removed.
Fig. 2, is an edge view of the invention.
Fig. 3, is a front view, and Fig. 4, a plan view of one form of advertising
apparatus, with which this my invention may be combined.
Fig. 5, is a detailed view of the intermittent wheel and its pinion.
Figs. 6 & 7, are detailed views of the driven crank, and Figs. 8 & 9, are detailed
views of the driving slotted crank.
Usually a spring motor clock movement is employed or adapted to carry out my
invention, but a weighted or other similar train of wheels may be used, having an
escapement action.
For purposes of description, I will assume it as adapted from an ordinary spring
motor clock movement, as shown in Figs. 1 & 2, in which 10 and 11 are the front
and back plates forming the framework carrying the moving parts &c.
12, is the spring motor box, one or more of which may be used according to
power required. 13, is the first motor wheel. 14, 15 & 16, are secondary wheels
with their respective pinions 17, 18 & 19, and respective arbors 20, 21 & 22. 23, is
the escapement wheel and 24 the balance wheel.
I select either of the wheel arbors, according to rapidity of movement required,
but generally the second wheel arbor 21. Upon this arbor is (of course) the
pinion 17, upon which is exerted a continuous impelling rotative force by the motor
spring: In the wheel 15 however, I provide intermittent teeth 26, that is to
say between each tooth there is a considerable blank space, (see Fig. 5). These
intermittent teeth as they come forward, engage with the pinion 18, similarly as
would the usual ordinary teeth upon such wheel, (as seen in Fig. 5). The
succeeding part of the train of wheels up to and including the balance wheel, is of
ordinary make. The arbor 21, of the intermittent toothed wheel, is extended a
convenient length upon the outside of the framework at 27. Upon this extended
part, 1 mount the slotted crank 28, having the slot 29, by which any suitable
apparatus for intermittently exhibiting advertisements may be driven. This
slotted crank engages with the pin crank 30, upon the spindle 31. In combination
with these two cranks, I employ the ratchet wheel 32, and pawl 33, which are
secured at any convenient position to the spindle 31.
34, is a rotating frame carried upon the spindle 31, which is arranged to receive
around its circumference a number of advertisements or views &c., corresponding
to the number of intermittent teeth 26, in wheel 15. Around this rotating frame is

page_text: the screen 35, having at one or more places in its circumference an opening 36,
through which the advertisements &c. may be seen.
Its action is therefore as follows:-The motor spring being wound up, the train
of wheels are driven forward in the usual manner, and an intermittent tooth is
caused to pass through and drive forward the pinion 18. At the time that this is
being done the crank pin 37, stands in advance of the driving side of the slot 29, of
the crank 28, and therefore the whole force of the motor spring is employed in
driving the train of wheels only, until the intermittent tooth has passed the pinion,
and is free to move forward until the next, tooth reaches the pinion. During this
interval however the slotted crank drives forward the crank pin 37, a given
distance, which, by reason of the momentum imparted, is carried on until it reaches
the opposite side of the slot 29, when it is held by the pawl 33, dropping into the
wheel 32. And so from time to time the process is repeated. By these means the
same motive power is alternately, distinctly and independently driving the inter-
mittent mechanism at one time, and the necessary train of wheelwork at another,
thus giving alternately the full power of the motor to each operation.
I wish it to be understood that I am aware that intermittent mechanism has been
already made and used for advertising purposes and therefore I do not claim such
mechanism broadly, but,
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination with a train of wheelwork, such as that herein described and
illustrated, having a continuous motive power, of the wheel 15, having intermittent
teeth 26, as and for the purposes set forth and shown.
2. The combination with a train of wheelwork, such as that herein described
and illustrated having a continuous motive power and further having an intermittent
tooth wheel 15, of the crank 28, having the slot 29, engaging with and driving
the crank pin 37, all substantially as set forth and shown.
3. The combination with a train of wheelwork, such as that herein described
and illustrated, having an intermittent tooth wheel 15, and slotted crank 28 of
the ratchet wheel 32, and pawl 33, as and for the purposes specified.
4. The combination with intermittent advertising apparatus such as frame 34,
screen 35, having spindle 31, and crank 30, of a train of wheelwork, having an
intermittent toothed wheel 15, slotted crank 28, all substantially as set forth
and shown.
