Improvements connected with Paper Feeding Attachments for
Printing and like Machines.
A communication from abroad by THOMAS A. BRIGGS, of Arlington, in the
State of Massachusetts, United States of America, Machinist.
I JOHN MAGRATH KELLY of 1 Charlotte Street Bedford Square in the County
of Middlesex, Merchant 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 relates to the attachment of an automatic paper feeding machine
to the feeding end of a printing machine.
And the object of this invention is to adapt the said paper feeding machine to be
readily attached to the frame of the printing press and also readily detached
therefrom when desired to feed the paper by hand to the printing machine.
And to that end the invention consists in the novel construction and combination
of parts hereinafter fully described and set forth in the claims.
In the annexed drawing,
Figs. 1 and 2 shew opposite sides of the frame of the paper feeding machine and
its connection with the printing machine ;
Fig. 3 is an end view of the same;
Fig. 4 is a horizontal transverse section on line X, X, Fig. 1.
Figs. 5 and 6 are vertical transverse sections respectively on lines Y, Y,
and Z, Z, Fig. 4, and
Fig. 7 is a vertical transverse section of the socket which contains the frame-
supporting roller, said section being taken in a plane at right angles to the axis of
the roller.
Similar letters of reference indicate corresponding parts.
A represents the feeding end of the main frame of a printing machine, and T
denotes the usual feed table over which to pass the sheets of paper to the printing
machine.
"
To the feeding end of the frame, is attached removably a supplemental frame B
consisting mainly of four posts P P and P P¹, two on each side of the frame,
and tied to each other by a broad cross bar B' at the bottom, heads B" B¹i
respectively at opposite side of the frame B and provided with sockets ss for the
reception of the upper ends of the posts, and a cross bar B1 tying said heads to
each other as shewn in Fig. 3 of the drawing.
It is preferred to hinge said supplemental frame to one side of the feed end of
the frame A by firmly securing to the latter the brackets C C which are formed
with vertical sleeves e e and through these sleeves pass the post P of the
supplemental frame. Said post constituting the pivot on which the supplemental
frame can be swung to or from the feed end of the printing machine as may be
desired. The opposite side of the supplemental frame is detachably connected to
the main frame by means of a suitable strap or hook has shewn in Fig. 2 of the
drawing.
Under the supplemental frame is a base plate D which is formed with a socket f
in which is stepped the post P by which the supplemental frame is hinged to the
main frame. The base plate is also formed with a segmental track t concentric to
the socket and extending underneath the frame B preferably at the centre of the
width thereof and rearward therefrom as best seen in Fig. 4 of the drawing.
Upon this track is mounted a roller c which supports the supplemental frame B
at the centre of its width and is adjustably connected thereto by means of a vertical
yoke b to which the roller is pivoted and which is seated in vertical grooves a' a' in

opposite sides of a socket a formed in the underside of the cross bar B₁ as shewn
in Figs. 5 6 and 7 of the drawing. Through the top of the cross bar E¹ central
over the yoke 6 is a screw threaded eye through which passes a set screw d which
bears with its lower end on top of the yoke and thereby supports the supplemental
frame on the roller c.
'
By turning the said set screw the frame B can be raised or lowered and properly
adjusted to its upright position.
Frepresents the table upon which is piled the sheets of paper to be fed to the
printing machine. This table is mounted on brackets F which are adjustably
connected to the rear posts P₁ P¹ of the supplemental frame B so as to allow said
table to be raised or lowered as may be required.
Said adjustable connection may be made in any suitable manner and is in this
case shown in the same form as represented in another application for Letters
Patent filed by me of even date herewith, and consists of two horizontal shafts 1, 1,
extending across the frame B and journaled in the brackets F', F', in front and
rear of the posts Pl Pl which latter are provided with cogs forming two vertical
: racks on each post. To each of the said shafts are secured two pinions 2, 2, which
engage the racks on the front and rear of the posts. At the outer side of one of
said posts is a vertical worm shaft 3, journaled to the frame B, and in ears 4, 4, on
the bracket F', and in front and rear of the worm shaft are worm wheels 5, 5, fixed
to the shafts 1, 1. To the upper end of the worm shaft 3, is attached a miter
pinion 6, meshing with a similar pinion 7, pivoted to the side of the frame B. The
latter pinion may be rotated either by a hand crank as indicated by dotted lines in
Fig. 1 of the drawing, or receive motion from the paper feeding mechanism as
shewn in the application for Letters Patent hereinbefore referred to. The rotation
of the worm shaft imparts rotary motion to the shafts 1, 1, which by means of the
engagement of their pinions 2, 2, with the vertical racks on the posts P' P¹ raise or
lower the table according to the direction in which the worm shaft is rotated.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. The combination, with the main frame of the printing machine of a supple-
mental frame removably connected to the paper feeding end of said main frame,
and a paper supporting table connected to the removeable frame, as set forth.
2. On a printing machine, the combination, with the main frame, of a supple-
mental frame removeably connected to the feeding end of said main frame, and a
paper supporting table carried on said frame adjustably in its elevation as set
forth.
3. On a printing machine, the combination with the main frame, of a supple-
mental frame hinged to one side of the feeding end of said main frame, and a paper
supporting table carried on said supplemental frame, as set forth.
4. On a printing machine, the combination, with the main frame, of a supple-
: mental frame hinged to one side of the feeding end of the main frame, a strap
detachably connecting said frames at the opposite side thereof, a paper supporting
table carried ou said supplemental frame, and a roller supporting the latter frame
at the centre of its width, substantially as set forth and shewn.
:
5. On a printing machine, the combination, with the main frame, of a supple-
mental frame hinged to one side of the feeding end of said main frame, a paper
supporting table carried on said supplemental frame, a segmental track under the
latter frame and concentric to the hinge thereof, and a roller connected to the
supplemental frame and traversing on the aforesaid track as set forth and shewn.
6. On a printing machine, the combination with the main frame A, of the
supplemental frame B hinged to one side of the feeding end of the main frame and
formed with a cross-bar B and with the socket a in the underside of said cross-bar
and having vertical grooves a' a' in opposite sides of said socket, the yoke 6 seated
movable vertically in said grooves, the roller c pivoted to said yoke, and the set

page_text: screw d passing through the top of the cross-bar and bearing on top of the yoke,
substantially as described and shewn.
7. The combination with the main frame A of the brackets C C attached to one
side of the feeding end of said frame and provided with the vertical sleeves e e, the
supplemental frame B provided with sleeves ss, the post P passing through the
aforesaid sleeves and hinging the supplemental frame to the main frame, the base
plate D provided with the socket f having stepped therein the post P and formed
with the track t concentric to said socket, and the roller c mounted on said track
and supporting the central portion of the supplemental frame, substantially as
described and shewn.
