Improvements in Means for Displaying Advertisements.
I. EDWARD LADMORE TURNER, of No. 3809, Prairie Avenue, in the City of
Chicago, in the County of Cook and State of Illinois, one of the United States
of America, Broker, do hereby declare the nature of this invention to be as
follows:-
:-
The invention comprises a box or casing provided with a glass front in which
a series of vertical frames or leaves for holding advertising matter, such as cards
or pictorial illustrations, are hinged centrally so as to revolve and be successively
presented to the front for display, and mechanism in connection with the casing
for automatically turning the different frames separately to view in front at
sufficient intervals to enable the cards to be inspected and read by persons standing
in front of the casing the frames being held stationary during the intervals
between the turns.
The operating mechanism consists of a barrel spring whose shaft is adapted for
winding the spring by means of a key and is provided with a toothed wheel
engaging a pinion upon a shaft. This shaft is provided with a large wheel
which has alternate toothed and smooth segments. This wheel works in conjunc-
tion with a pinion which is toothed upon one side and smooth upon the opposite
side. The pinion is mounted upon a shaft journaled in the top and bottom plates
of the frame-work in which the operating mechanism is supported.
The latter shaft is under tension of a spring which is adapted to produce a half
revolution of said shaft. A stop pin, operating upon the tooth at one end of
the tooth part of pinion, holds the shaft from being further revolved by the
spring. Gears connect the power with a governor for regulating the speed.
The shaft projects through the top of the casing, and to the lower end of said
shaft is attached an arm which has a vibrating inclined pawl or dog whose tip
end falls below a horizontal plane coincident with said arm but may be elevated
so as to come within said horizontal plane which is just above the top edges
of the display frames. The arm oscillates through an arc of a little more than
180 degrees. A pawl strikes the upper edge of one of the display frames in
the backward movement and is thereby elevated so as to pass it, then it drops
back so as to engage the frame and turn it over to the opposite side of the casing
on the forward movement of the arm. The toothed segments of the wheel
engaging the tooth segment of the pinion give the arm its movement in one
direction and the spring on shaft gives the opposite movement during the passage
of the untoothed segments of said wheel and pinion. At each alternate movement
of the arm one of the display frames is turned by a quick movement from one
side of the casing to the other which also moves the whole lot of frames forward
so that another of them is brought within the reach of the pawl, in the next
backward movement. The display frames all remain stationary during the
interval of the arm's backward movement.

I, EDWARD LADMORE TURNER. Broker, of No. 3809, Prairie Avenue, Chicago,
Illinois, one of the United States of North America, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
The invention comprises a box or casing provided with a glass front in which
a series of vertical frames or leaves for holding advertising matter, such as cards
or pictorial illustrations, are hinged centrally so as to revolve and be successively
presented to the front for display, and mechanism in connection with the casing
for automatically turning the different frames separately to view in front at
sufficient intervals to enable the cards to be inspected and read by persons standing
in front of the casing the frames being held stationary during the intervals
between the turns.
An embodiment of the invention is illustrated by the accompanying drawings
in which;
Figure 1 represents a horizontal section of the casing on a plane just above
the vertical display frames.
Figure 2 is a top or plan view of the mechanism, which is designed to be
mounted on the top of the casing, for automatically operating the display frames.
Figure 3 is a detail showing a fragment of a detached part in plan view.
Figure 4 is a detail showing in elevation a fragment of another part employed
in conjunction with the part shown in Figure 3.
Figure 5 is a detail showing in perspective a fragment of an arm, and a gravi-
tating pawl or dog detached from the arm.
In Figure 1 of the drawings A is the casing with a glass front B.
display frames the upper edges only of which are portrayed. These frames are
C are the
separately pivoted to a vertical rod D having its ends respectively fixed in the
bottom and top of the casing near the center, the frames being adapted to revolve
around the rod and being provided with grooves or other suitable means for
holding cards or pictures upon their opposite sides for display.
The operating mechanism is illustrated in Figures 2, 3, A, & 5 of the drawings
and in these figures the dotted lines E represent a barrel spring whose shaft F
is adapted for winding the spring by means of a key and is provided with a
toothed wheel engaging a pinion upon a shaft G. The shaft G is provided with
a large wheel H which has alternate toothed and smooth segments, h¹. The
wheel H works in conjunction with a pinion I which is toothed upon one side
and smooth upon the opposite side. The pinion I is mounted upon a shaft J
journaled in the top and bottom plates K of the frame-work in which the
operating mechanism is supported.
The shaft J is under tension of a spring L which is adapted to produce a half
revolution of said shaft. A stop pin M, operating upon the tooth at one end
of the tooth part of pinion I, holds the shaft from being further revolved by
the spring. Gears N, O, connect the power with a governor P for regulating the
speed. The shaft projects through the top of the casing A, and to the lower end
of said shaft is attached an arm Q which has a vibrating inclined pawl or dog S
whose tip end falls below a horizontal plane coincident with said arm but may
be elevated so as to come within said horizontal plane which is just above the
top edges of the display frames. The arm oscillates through an arc of a little
more than 180 degrees as shown by dotted lines in Figure 1. The pawl strikes
the upper edge of one of the display frames in the backward movement and is

page_text: thereby elevated so as to pass it, then it drops back so as to engage the frame
and turn it over to the opposite side of the casing on the forward movement
of the arm. The toothed segments of the wheel H engaging the tooth segment
of the pinion I give the arm Q its movement in one direction, and the spring L
on shaft J gives the opposite movement during the passage of the untoothed
segments of said wheel and pinion. At each alternate movement of the arm one
of the display frames is turned by a quick movement from one side of the casing
to the other which also moves the whole lot of frames forward so that another
of them is brought within the reach of the pawl, in the next backward movement.
The display frames all remain stationary during the interval of the arm's back-
ward movement.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The display frames suitably mounted in combination with the mechanism
for automatically turning them separately at intervals in the manner substantially
as described and illustrated on the accompanying drawings.
