Improvements in Paper Holding Devices.
I, EMORY AUDELL TRUSSELL, a resident of the City of St. Louis, in the State of
Missouri, one of the United States of North America, Manufacturing Stationer,
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 relates to a device for holding sheets of paper, the device being of
a construction capable of receiving the insertion of a quantity of sheets, one or
more at a time, and holding those first inserted firmly while the subsequently
inserted sheets are being inserted. The device is capable of employment upon a
clip-board; or as a paper holding clip without a board; or it is capable of employ-
ment in connection with book-binding machines, such as shown and described.
in my application for Letters-Patent of the United States, filed February 15, 1897,
under Serial number 623,552.
My invention consists in features of novelty hereinafter fully described and
pointed out in the claims.
Referring to the drawings:-
Figure I is a top view of my improvement applied to a clip-board.
Fig. II is a top view of the base frame and secondary clip bar, showing the
pivot arms of the main clip bar in section, the controlling spring and operating
lever being omitted.
Fig. III is a rear view of the device shown in Fig. I.
Fig. IV is a side view, showing the main clip bar elevated and the secondary
bar depressed.
Fig. V is a side view, showing the main clip bar depressed and the secondary
bar clevated.

Fig. VII illustrates a section taken on line VII-VII, Fig. VIII and shows
the parts beneath said line in face view.
Fig. VIII is a side view of the modified form with the main clip-bar depressed
and the secondary bar elevated.
Fig. IX is a side view showing the bars in the reverse position from that shown
in Fig. VIII.

In the drawings, and referring first to Figs. I to V inclusive, 1 designates a
clip board, to which is secured a base frame 2. On the frame 2 are uprights 3.
that form stops to limit the extent of insertion of the sheets of paper when placed
in the device.
At the rear portion of the base frame are hanger arms 4 in which a shaft 5
is mounted.
6 designates the main clip bar provided with arms 7 that are pivoted to the
shaft 5.
On the shaft 5 is a spring 8, wound in opposite direction from the central
portion of said shaft, having a central loop 10 that bears against the board 1.
an having its ends resting in contact with the arms 7, whereby the pressure of
[Price 8d.]

page_text: the spring is caused to be exerted upon the clip bar 6 for the purpose of throwing
it downward.
This
11 designates a secondary clip bar having arms 12 pivoted to the shaft 5.
secondary bar is provided with a slot 13, in which an operating lever 14 is pivotally
mounted upon a pin 15.
The operating lever is provided with a cam 16 that a backward throw of the
lever moves into contact with and rides against the under side of the frame 6" of
the main clip bar 6, thus causing the main clip bar to be elevated, and the pressure
of the spring 8 upon the main clip bar forms a pressure upon such main bar
sufficient to cause the secondary bar to be depressed on the main bar being
elevated by the cam.
When the operating lever is again thrown forward, the spring 8 forces the main
bar downward and the secondary bar is elevated by means of a spring 17 on the
shaft 5, which spring bears against the rear portion of the frame 11" of the bar 11
and is in contact with the board 1.
In the operation of the device, the operating lever is thrown rearwardly, as
seen in Fig. IV, and one or more sheets of paper A are inserted with their ends
resting upon the bar 11 and against the stops 3 which limit the extent of their
insertion. The operating lever is then thrown forward into the position shown in
Fig. V, in which action, the main bar 6 first comes into contact with the sheets
of paper and holds them firmly into contact with the board 1. When the bar 6
has reached contact with the sheet or sheets of paper inserted, which it does before
the lever has reached the limit of its forward movement, the spring 17 causes the
secondary bar to be elevated, thus freeing it from the paper previously resting
upon it and it ascends to the position in which it is shown in Fig. V. When it
is desired to insert additional sheets of paper, the operating lever is again thrown
backward and before the main clip bar leaves contact with the inserted paper, the
secondary bar reaches contact therewith and holds the inserted paper firmly while
the additional paper is inserted in the same manner as before and the main bar
is descending upon the paper, as before described.
In the modified form of device shown in Figs. VI to IX inclusive, 2ª designates
the base frame provided with a stop 3ª and hanger arms 4ª. 6b designates the
main clip bar. The frame 6° carries arms 7ª that are pivotally mounted upon
the shaft 5 supported in the hanger arms 4.
The rear end of the frame 6 is provided with a finger hold 6d.
The main clip bar 6b is depressed by means of a spring 8, the ends of which
bear against the hanger arms 4ª, while its central loop bears against the frame 6°.
The secondary clip bar 11b is pivotally connected to the shaft 5" and is controlled
by a spring 17 that bears against the frame of the main clip bar and against the
secondary bar, by means of which spring the secondary bar is held normally
with its forward end elevated, as shown in Fig. VIII. In so far as regards the
reciprocating action of the clip bars, the operation and function of device shown in
Figs. I to V inclusive and VI to IX inclusive, is identical.
In the operation of the modified form, the papers may be inserted by elevating
the main bar and placing it in the position shown in Fig. VIII, or, by grasping
the rear finger holds of both bars, the secondary bar will be depressed as shown
in Fig. IX and the main bar will be elevated. The papers may then be inserted
upon the secondary bar as illustrated in Fig. IX in the same manner as described
with relation to the main form of device and, on the lowering of the main bar
by its release from the grasp of the operator, the secondary bar will ascend under
the pressure of the spring 17ª.
In the employment of the device shown in Figs. I to V inclusive, the sheets
of paper may be all removed at once by throwing the lever 14 rearwardly and
depressing it, thus elevating both of the bars and relieving the papers from their
pressure. A body of sheets may also be inserted by operating the parts in the
same manner.
In the form of device shown in Figs. VI to IX inclusive, the same result may
be accomplished by elevating both of the bars 6ª and 11ª simultaneously
