I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, 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 :--
The object of this Invention is to provide a new and improved machine, for pasting
together the sheets forming a pamphlet.
The Invention consists in a pasting machine constructed with a sliding table, and
with a swinging paste-box provided with a dise for distributing paste on a line, across
sheets held on the sliding table. The sliding table is provided with a cam ridge for
raising the paste-box during the movement of the table in one direction, and with a
spring standard for holding the pasie-box raised, so that the sheets can pass under
it during the movement of the table in one direction, without receiving any paste.
The Invention also consists in paris and details, and combinations of the same, as
will be fully described, and set forth hereinafter.
Reference is to be had to the accompanying drawings forming a part of this specifi-
cation, in which Figure 1 is a longitudinal sectional elevation of the improved hand
pasting machine on the line -x of Figure 4. Figure 2 is a cross sectional elevation
of the same on the line y-y of Figure 4. Figure 3 is a side view of the paste box,
parts being shown in section. Figure 4 is a plan view of the machine.
Similar letters of reference indicate corresponding parts in all the figures.
A table A is fitted to slide on a base board B, the said base board being provided at
its sides with grooves for receiving the side edges of the sliding table A. The sliding

page_text: table is provided at its front end with a. transverse undercut cross bar or handle A'.
Two standards Crise from the sides of the base board, and in the upper ends of the
said standards a transverse shaft D is fixed, and on the said shaft D an adjustable
sleeve E is fixed by means of a binding screw F. On the sleeve E as a bearing a
hollow boss G is mounted to rock which is provided with a segmental slot I through
which the screw F passes, the screw F thus serving to limit the rocking movements
of the boss.
On the said rocking boss G a plate H is fixed by screws H', which plate projects
slightly upward and toward the rear, and to the front of the boss G is fastened
a downwardly inclined arın J carrying a paste cup K, which is provided in its bottom
with a longitudinal slot L. In two arms M projecting downward from the bottom of
the cup K a disc N is journaled in such a manner that its edge passes into the slot L,
but does not project above the top surface of the bottom of the said paste box or cup.
The edge of the disk N is preferably serrated. An inclined gutter or trough O is
provided with a screw-threaded stem P projecting from the inner end at one side,
which stem passes through a suitable guide casting P¹ on the under side of the box K,
and the said stem is screwed through a nut Q held to revolve in a plate Q' held on
the front of the box. The gutter is provided at its inner end with a slot through
which part of the disk N can pass. On that end of the sliding table A opposite the
one provided with the handle piece A an upright spring R is secured, which is bent
downward at its upper end R in such a manner that the free end of the plate H will
be higher from the surface of the table A when the disc N rests on the sheets on the
table than the free end of the spring R.
Pins S project upward from the table at each side facilitating the adjustment of the
sheets. On the upper surface of the table and near the end provided with the upright
spring R a cam ridge or projection T is arranged in such a manner that it can strike
against one of the arms M of the paste box or cup when the table A is reciprocated.
The cam ridge T is preferably held in such a manner that it can be adjusted according
to the width of the paper, and to correspond with the adjustment of the sleeve E.
The operation is as follows:
The sliding table A is drawn in the direction of the arrow a' as far as possible,
whereby the cam ridge T is passed under one of the arms M or under the shaft of
the disc N and raises the same so high that the bottom of the said disc will be above
the uppermost sheet W placed on the table, the spring standard R will then be near
the shaft D and the free end of the said spring R will be directly over the plate H. A
sheet W is then placed on the table A or on the other sheets in such a manner that
the registering holes in the said sheet are above the pins S which pass into the said
holes. The table A is moved in the inverse direction of the arrow a', thus causing
the spring standard R which slides along the plate H to press down the free end of the
plate H, thereby raising the paste cup or box and its disc and the disc N will be carried
over the sheets without coming in contact with the same or distributing any paste on
the said sheets. When the spring standard R passes the free end of the plate H the said
plate is released and the paste cup drops of its own weight, thus causing the rim of
the disc N to rest on the uppermost sheet W. If then the table is again moved in
the direction of the arrow a', the disc N will run over the uppermost sheet and deposit
a line of paste on the middle of the same. When the disc arrives at the end of the
sheet, the cam ridge T strikes one of the arms M or the shaft of the disc N, and raises
the said disk and the paste cup so as to prevent the paste from being distributed on
the table the free end of the spring R then snaps on the plate H, and if the table A
is moved in the inverse direction of the arrow a, the spring holds the dise N raised in
the manner previously described, and so on. The scraper or trough O, through which
the edge of the disc passes, scrapes off all the superfluous mucilage or other paste.
By means of the nut Q and the screw P the scraper, gutter, or trough can be arranged
to scrape off more or less of the paste or mucilage. As the rim of the disc N does not
project above the upper surface of the bottom of the paste box, and as the rim of the
disc fits quite closely in the slot L, the rim of the disc only will carry the mucilage
or paste from the box, and no mucilage or paste will adhere to the sides of the disc.

page_text: The above described machine gums the pages in a straight line along the center,
and in order to form the pamphlet all that is necessary is to gum a sheet in the manner
described, place another one on it, gum the second sheet, and so on, and when a
sufficient number sheets have been united the completed pamphlet is removed.
The paste distributing device can be adjusted according to the length of the
pamphlet.
Having now particularly described and ascertained the nature of the said Invention,
and in what manner the same is to be performed, I declare that what I claim is-
1. A pasting machine. constructed, substantially as herein shown and described,
with a sliding table, and with a pivoted paste box provided with a dise for distributing
the paste on a line across the sheet placed on the table, as set forth.
2. A pasting machine constructed with a swinging paste box provided with a paste
distributing disc and with a spring for holding the paste box and its disc raised when
the sheet is passed under it in one direction, said paste box being lowered by gravity
when the sheet passes in the inverse direction, substantially as herein shown and
described.
3. In a pasting machine, the combination with a swinging paste box and a dis-
tributing disc of a sliding table for carrying the sheets, and a spring standard secured
on the said table and adapted to hold the paste box and its disc raised, substantially
as herein shown and described.
4. In a pasting machine, the combination with a paste box and a paste distributing
disc, of a sliding table for carrying the sheet and a cam ridge on the table and adapted

5. In a pasting machine, the combination with a swinging paste box having a paste
distributing disc, of a boss G, on which the paste box is held, the sleeve E on which
the boss Grevolves, the shaft D on which the sleeve is mounted, and a screw for
locking the sleeve E in place, the said screw passing through a slot in the boss G,
substantially as herein shown and described.
6. In a pasting machine, the combination with a transverse shaft suitably supported
of a boss swinging on the same, a paste box carried at one side of the boss and a plate
on the other, a sliding table, and a standard secured on the table and adapted to press
