Figure, 2, is a side elevation of the cover, part being brókén away.
Figure, 3, is a similar view of a cover closed.
Figure, 4, is a plan of a portion of the cover open.
Figure, 5, is a view of the spring and strengthening plate.
Figure, 6, is a detail section, showing the reinforcing plate, and
Figure, 7, is a detail showing position of sheet in writing sales check.
A, indicates the cover. This cover is jointed at, B, and has a clamp tablet, C,
which is preferably connected by a flexible part, D, with one end of the cover.
The clamp tablet, C, is preferably strengthened by an inserted metallic plate, E,
having a turned over edge or loop, F.
This plate, E, serves to stiffen the clamp tablet and hold it always flat. It also
serves to prevent wear of the material of the cover, which is preferably paste-board
covered with leather.
The turned over edge of the metallic plate serves as a socket or hinge for the
cross-bar, H, of the metallic spring, H. This spring, H, formed preferably of a
single wire, has its ends, I, I, seated in the body; A; of the cover near the
edges, A¹, A¹.
Where the part, H₁, of the wire spring, H, passes through the clamp.tablet, C, it
causes a projecting rib to protrude below the general surface of the tablet.
This rib bears on the inclosed sheets in a manner which will be hereinafter
explained.
The sheets forming the sales or memorandum book, may be made up in a pad, K,
with a black or transfer leaf on top, the black leaf extending about half the length
of the pad, from the top end, M, of the pad to about the line of perforations, N,
across the sheets constituting the pad, although in some forms the black leaf may
be shorter.

page_text: The sheets of the pad may also have a line of perforations, O, extending across
the sheets near the bottom.
These perforations, O, separate the sales check, P, from the body of the sheet.
The lower end of the top sheet may be turned over the black leaf and clamp
tablet, the check, P, resting on the tablet, C, as in figure, 7.
The check, P, then rests on the tablet, C, and may then be written without
leaving a transfer on the stub.
The part, K¹, will, when written, leave a duplicate of the written matter on
part, K, beneath.
The projecting rib of the tablet, C, is held by the spring, H, firmly down upon
the pad, just above the upper line of perforations, Q.
This enables the salesman to readily remove the upper sheet of the pad from the
stub, without tendency to tear the stub, the rib holding all the sheets firmly in
place for their full width so preventing any tear except in the line of the rib.
The cover sections and the tablet, C, are stiff, and will hold the sheets of the pad
flat, when the head of the pad is entered between the clamping tablet and the
upper section of the cover.
The tablet also affords a smooth surface on which the check, P, or any other part
of the sheet may be written of which no duplicate is required.
The spring, H, being attached at the sides of the cover and also at the sides of
the clamp tablet will leave the face of the tablet and the back of the cover free
from projections, so that a smooth surface is presented on which a sheet may be
spread for writing, and the device is much more durable than if made with surface
projections.
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
1st. The combination with the cover of a book, of a clamping tablet and a spring
attached to the sides of the cover below the tablet at the sides thereof, as set forth.
2nd. The combination with the cover of a sales or memorandom book, of an end
clamping tablet, an inclosed metallic plate in said tablet, and a spring attached to
the sides of the cover, and bearing on the metallic plate in the tablet, as set forth.
3rd. The combination with a sales book cover, of a clamping tablet having a rib
across the under surface, and a spring connected with the cover and bearing the
tablet toward the cover substantially as described.
4th. The combination with cover, A, of the clamp tablet, C, held toward the
cover by side springs connected with the cover, and the pad of sheets having a line
of perforations near the edge of the tablet.
5th. The sales book described, having stiff cover jointed centrally, the spring,
tablet and pad of leaves perforated on a line near the edge of the tablet, perforated
centrally, and perforated near the end away from the tablet, as set forth.
6th. The book cover, A, of stiff material centrally jointed, the tablet, C, the side
springs, H, attached to the cover and bearing on the inner end of the tablet, the
pad of sheets, K, perforated on the lines, N, O, Q, and the transfer leaf beld under
the tablet and shorter than the leaves of the pad, as set forth.
7th. The book cover, A, and the pad of sheets perforated on a line transversely
across the cover, the transfer leaf and the pad secured to the cover by means of a
rigid clamp bearing on the sheets near the line of perforations.
Dated this 29th day of December 1885.
