PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Holding Paper and Paste Board
whilst Drying.
I, WILLIAM ROBERT MARCHANT of Purfleet Wharf, Upper Thames Street in
the City of London, Paper Manufacturer, do hereby declare the nature of this
invention to be as follows:-
-
This invention has for its object improvements in apparatus for holding paper and
paste board whilst drying.
At the present time drying frames are in use in which clips with nipping pawls are
employed to hold the sheets. These drying frames are supported overhead and are
generally moveable along rails from place to place.
In placing the sheets in the frames, the sheets are thrust upwards one or more at
a time their upper edges enter readily past the heads of the pawls which the
frame carries but the pawls prevent a downward movement. The sheets consequently
remain suspended.
The removal of the sheets from drying frames of this sort is troublesome and
occupies much time, the clips having to be released one at a time.
According to my invention I couple the pawls together in groups in such manner
that all the pawls in a group can be simultaneously lifted. The group extends over
as many sheets as the workman can at one time receive in his arms and pendants are
provided so arranged that by a pull or thrust upon the pendant the lifting of many
pawls is brought about.
In the use of the apparatus the workman places his arm around the group of
suspended sheets to be released and then operates upon the pendant-thereby he
lets down at one operation as many sheets as he is able to hold in place of taking
the sheets down one at a time as heretofore.
Or one workman may release whilst another receives the sheets.

Improvements in Apparatus for Holding Paper and Paste Board
whilst Drying.
I, WILLIAM ROBERT MARCHANT, of Purfleet Wharf, Upper Thames Street in
the City of London, Paper Manufacturer, 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 has for its object improvements in apparatus for holding paper and
paste board whilst drying..
At the present time drying frames are in use in which clips with nipping pawls
are employed to hold the sheets. These drying frames are supported overhead and
are generally moveable along rails from place to place.
In placing the sheets in the frames, the sheets are thrust upwards one or more
at a time their upper edges enter readily past the heads of the pawls which the
frame carries but the pawls prevent a downward movement. The sheets consequently
remain suspended.
The removal of the sheets from drying frames of this sort is troublesome and
occupies much time, the clips having to be released one at a time..

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a group of paper clips provided in accordance with
my invention with mechanism for simultaneously opening all the clips and releasing
the sheets which they hold.
Figure 2 is a transverse vertical section and shows two such groups with sheets
held between them.
Figure 3 shows full size a few of the clips in side elevation and Figure 4 is a
corresponding transverse vertical section.
e e are
a a are fixed supports upon which the clip bearing bars bb rest at their ends.
cc are wooden blocks fixed to the bars b on the underside at equal distances apart.
dd are sheet metal side plates fixed to the bars band to the blocks c.
wooden tongues inserted between the side plates d and pivotted to them at el e¹.
ff are rods lying on the top of the bearing bars and capable of sliding
longitudinally a short distance; there are elongated holes through the rods f
at ff and screws passing through the holes are fixed into the bars b. 6* and f* are
stops upon the bars band rods f respectively to limit the longitudinal movement
of the rods f. 9 9 are links of thin sheet metal; each is connected at its lower end
to a tongue e by a screw passing through the link and into the tongue; on this
screw the link can turn freely. At the upper end of the link there is an elongated
hole through which another screw passes and penetrates the rod f. h is a bell crank
lever mounted upon the support a; there is one of these levers for each rod f; at
the upper end of the lever there is a fork in which the end of the rod flies and
it is loosely connected by a pin fixed in the rod and passing through holes in the
forked ends of the bell crank lever. The other end of the lever A is connected to
a rod i by which it can be moved. kk are the sheets hanging in the clips to dry.
The clips it will be seen are capable of independent movement and can yield freely
to allow the sheets to be thrust upwards between the tongue e and the block b
and then automatically the sheet becomes held firmly and securely. Nevertheless
the sheets which are thus placed in the clips one by one can be all liberated
simultaneously by pulling the rods i.
The sheets when set free fall simultaneously and can be collected in bundles by
the hands of the workman; or the sheets may be caught in baskets, boxes, trays,
nets, cloths or the like. Or the group of clips may extend only over as many sheets as
a workman can at one time receive in his arms; or two or more workmen may work
together. If the sheets be wide they may be held at their upper edges by three or
more clips in place of by two as the drawings indicate.
The tongues are sufficiently free to permit of some lateral shrinkage of the sheets
in drying; if this be insufficient the bars 6 may be moveable on the supports a and
able to yield to the tension of the sheets tending to draw them together. If the
sheets be thin and tender as well as of large dimensions the bars b should be
suspended in such manner as to admit of easy movement. The retaining clips may
be variously constructed without departing from my invention; the essential
feature being that the clips can open independently to receive the sheets and close
independently to retain them but nevertheless can be opened simultaneously in
groups to release the sheets.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
