Improvements in Appliances for Automatically Feeding Sheets of
Paper to Printing and like Machines.
WILLIAM BRIDGEWATER, of 30, St. Peters Lane, Leicester, in the County of
Leicester, do hereby declare the nature of this invention to be as follows:
This invention relates to the class of machines which are designed to feed
successive sheets of paper one at a time to printing folding ruling and like
machines. The object of my invention is to make the arching or buckling of
one sheet at a time more certain. To carry out my invention I place an adjust-
able bar along the front of and parallel to the arching or buckling roller or
other device for that purpose adjustable as to distance from the said roller or
device leaving space between them suitable for arching or buckling the class
of paper operated on especially suitable when such roller or other device is not
adjustable. The bar is made to rest upon the pile of paper during the operation
of arching or buckling it is then made to rise leaving the sheet of paper free
to be carried by the feeding appliance to the tapes. To raise or lower the said
bar at the proper time suitable levers and cams are employed. In place of a
bar a roller may be used.

Improvements in Appliances for Automatically Feeding Sheets of
Paper to Printing and like Machines.
I, WILLIAM BRIDGEWATER, of 30, St. Peter's Lane, Leicester, in the County
of Leicester, Engineer and Machinist, 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 machines designed to successively feed sheets of
paper, one at a time, to printing, folding, ruling and like machines, the object
of the invention being to make the arching or buckling of one sheet at a time
more certain. To carry out the invention therefore, an adjustable bar is placed
along the front of and parallel to an arching or buckling roller or equivalent,
the said bar being adjustable as to distance from said arching or buckling roller
so as to regulate the arch or buckle required to be formed in the top sheet
according to the class or texture of paper operated upon.
The said bar is caused to rest upon the top sheet of the pile of paper during

page_text: the arching or buckling operation, and is then raised to leave the sheet of paper
free to be carried by the feeding appliance to the tapes or other devices for
carrying it off.
The present invention is illustrated in the accompanying drawing in which,
Figures 1 and 2 are sectional elevations through the front part of a feeding
machine showing this invention applied thereto.
Figure 3 is a plan taken on the line of Figure 1.
Figure 4 is an end elevation and Figure 5 is a sectional elevation of the
mechanism comprised in this invention.
Figure 6' is a vertical central section of one of the brackets for carrying the
bar before mentioned.
Similar reference characters will be employed to designate corresponding
parts, and it will be understood that the mechanism for one side only of the
machine, is shown in the drawing, duplicate mechanism being required, (right
and left hand).
In Figures 1 and 2 are shown two parallel rollers A and B, both of which,
during the operation of the machine, are, sequentially raised clear of the top
sheet or revolved in contact therewith, by mechanism outside the scope of this
invention, but described and illustrated in the Specification of my Patent
No. 21,721 of 1898.
:
Placed between the said rollers A and B and parallel therewith is a bar C
capable of adjustment in relation to the arching or buckling roller B to regulato
the amount of arch or buckle formed successively in each top sheet by the said
roller B.
To operate upon or feed forward each top sheet the bar Crests upon the top
sheet of the pile of paper while the roller B is revolved in the direction of the
arrows (see Figures 1 and 2) in contact with the said top sheet, and the roller A
is stationary and may also rest upon the top sheet of the pile or be held clear
thereof, and when the arch or buckle has been formed, the har C is raised by
mechanism hereinafter described and illustrated and the roller A is revolved in
contact with the top sheet to feed the latter forward, during which operation the
roller B may be raised clear of the sheet or revolved on the latter in conjunction
with the feed roller A.
A. feeding machine comprising features such as described may be of any con-
venient width with the rollers A and B and the bar Creaching approximately
across the full width thereof, the rollers A and B being in length somewhat
less than the width of the machine, the spindle of said rollers however being
of sufficient length to be carried in the side frames of the machine.
The said bar C is carried loosely upon a spindle D. the ends of the latter
being received into and carried by right and left brackets E, one at each side
of the machine. The said brackets E are provided with projections EE which
rest upon the tops of bars G by which they are supported, and plates E2 are
secured by screws E3 to the bottom of said brackets E.
On each end of the spindle D is fixed a toothed wheel E to gear with the rack
teeth G¹ formed in the upper edges of the bars, G the ends of the latter abutting
against projections HH formed on the side frames. H' of the machine; it will
be seen therefore that by turning the spindle D by means of the finger lugs D¹
on either of the spur wheels F (or a handle not shown which may be fixed on
either end of the said spindle D) the bar C may be horizontally adjusted in
parallel relation to the roller B for the purpose herein before mentioned.
The bar C is raised clear of the top sheet between each arching or buckling
operation, or lowered upon it as required to assist in forming the arch or buckle,
by means of slides JJ secured to rods K which are attached by pins K' to
levers L fixed on the shaft M. One of the levers L has an extension L' (as
shown in Figure 1) and a roller or runner L2 on the said extension L' rides
upon a cam N which presses outward as required the roller or runner LP and con-
sequently moves forward the rods K and slides JJ fixed thercon. Springs L2

page_text: serve to ensure the withdrawal of the levers L, rods K, and slides JJ to again
lower the bar C upon the pile.
The said slides JJ engage the inclines of the plates 00 fixed by the screws 0¹0¹
to the bars G.
It will be readily seen therefore that as the cam N or equivalent presses
outward the roller or runner L2, the rods K will be moved forward causing the
slides JJ to engage the inclines of the plates 00, thereby raising the bars G,
brackets E and the bar C as before mentioned.
A single sheet of paper (a-a) is represented by the dotted line in Figure 1,
and clearly shows the arch or buckle between the bar C and roller B, only the
one sheet being shown so that a confusion of lines is prevented.
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:
1. In a paper feeding machine, the combination with the arching or buckling
roll B of a bar Cor equivalent adjustable horizontally on its supports in relation
to the said roll B, the bar C and supports therefor being movable vertically
and mechanism for imparting such movement, substantially as described.
2. In a paper feeding machine in combination with the arching or buckling
roll B, a bar C or equivalent loosely carried on a spindle D, wheels FF on said
spindle and rack bars GG provided with teeth G with which the teeth of the
wheels FF engage so that the bar C may be adjusted horizontally in relation
to the roll B according to the texture of the paper under operation, substantially
as described and illustrated in the accompanying drawing.
3. In a paper feeding machine in combination with the arching or buckling
roll B, a bar C or equivalent loosely carried on a spindle D, supporting
brackets EE for said spindle and projections EE on said brackets resting on
the top of rack bars GG and plates E2 under the said rack bars G G substantially
as described and illustrated in the accompanying drawing.
4. In a paper feeding machine in combination with the arching or buckling
roll B, a bar C or equivalent, mechanism for horizontally adjusting the bar C
in relation to the roll B and rack bars G G for supporting the bar C, said rack
bars being given a vertical movement by means of rods having a horizontal
reciprocating movement and engaging inclined plates on said rack bars GG
substantially as described and illustrated in the accompanying drawing.
5. The combination of the roll B, bar C, spindle D. wheels FF. rack bars GG,
inclined plates 00, slides JJ, rods KK, and levers LL. operated in the manner
and for the purpose substantially as described and illustrated in the accom-
panying drawing.
