Improvements in Apparatus for Successively Feeding Sheets of Paper
or the like to Printing and other Machines.
I, JOSEPH BOYLAN, of 98, Rupert Street, Bradford, in the County of York,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in mechanism or apparatus for
successively feeding sheets of paper or the like to printing and other machines
from either a large or small pile.
To facilitate feathering" the sheets I employ a suitable finger or stroker
pivoted near one end to a vibrating arm. The other end of the finger rests
during its forward movement upon the paper with sufficient pressure to have a
feathering action on the upper sheet or sheets and this pressure is relieved or
completely removed during the reverse movement of the finger. A spring is
preferably provided coupled to the rear end of the finger to apply the pressure
to the finger and provision may be made for adjusting the pressure. A cam or
tappet or equivalent device is provided to relieve or remove the pressure of the
finger during its reverse movement. Two or more fingers may be used and they
may be made adjustable.
on the
To drive the feed shaft I may fit it with a crank and put a crank
end of the cam. shaft of the printing machine or an equivalent shaft and couple
the two cranks together by a connecting rod. The connecting rod is connected
by a link to a fixed stud and the cranks are of equal size and the link is con-
nected to the middle of the connecting rod. The crank of the feed shaft is
provided with a short slot for the pin of the connecting rod and it is preferably
loosely mounted on the shaft, and motion may be communicated to the shaft by a
pawl on a stud in the crank engaging a notch or tooth in a disc rigidly fixed to
the shaft. This permits the feed to be readily stopped and it may be operated
intermittently by a star piece arranged to disengage the pawl say, at every other
stroke..
T
To also stop the tape rollers intermittently I drive their pinions by means of
a wheel having a blank space or spaces without teeth at intervals, and to hold the
pinion stationary and to retain it in position for the teeth to re-engage again I
employ a concentric swell on the driving wheel to engage a check piece with
curved sides fixed on the side of the pinion.
When the table approaches its maximum height a bell may he rung to give
audible indication that there is only a few sheets remaining. For this purpose
the bell may be lifted by the table into position to be rung by an arm or finger
on the rocking shaft of the feed motion.

I, JOSEPH BOYLAN, of 98, Rupert Street, Bradford, in the County of York,
Mechanical Engineer, 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 improvements in mechanism or apparatus for
successively feeding sheets of paper or the like to printing and other machines
from either a large or small pile, and particularly to the mechanism for which
Letters Patent were granted to me dated the 11th day of May 1898, and
numbered 10729.
To fully describe my invention reference is made to the accompanying sheets
of drawings forming a part of this specification, in which similar letters of
reference indicate corresponding parts in each of the figures.
Figure 1, is a plan view of such portion of the feed mechanism described in
the specification of the above mentioned Letters Patent as are necessary to describe
my present improvements.
Figuro 2, is a cross section of the same on the broken line a, b, and
Figure 3, is a side elevation.
Figure 4, is a section on the broken line y, z of the wheels for driving the
tapo rollers.
Figure 5, is a plan view of such parts of the machine as are necessary to
illustrate my improved method of driving the feed shaft.
Figure 6, is a side elevation of the same.
The same letters and figures of reference designating the parts in the drawings
of the above cited specification are used in the drawings annexed hereto.
The
To facilitate feathering the sheets P I employ fingers 2 at each side loosely
mounted upon a stud 3 fixed in arms 4 one of which is adjustably mounted on
the shaft 5 on each side of the rollers E referred to in the above cited specification.
The shaft 5 is carried by an arm 6 at each end loosely mounted on the shaft Ba
and actuated by the connecting rod from the arm 7 on the shaft 1.
fingers 2 bear upon the sheets P during their forward movement thus tending to
feather the sheets forward but they are lifted more or less out of contact with
the sheets on their return by means of the cam 9 engaging the arm 10 on the
shaft 5 thereby lifting the arms 4 and the latter each have a stud 11 which
engages the underside of the finger to lift it. The pressure of the fingers upon
the paper is regulated by the spring 12 stretched between the stud 13 of each finger
and one of the studs 14 on the arm 4 carrying it.
To drive the shaft D9 I employ a crank 15 upon its outer end and I connect
it by the rod 16 to a crank 17 on the cam shaft 18. The middle of the rod 16 is
connected by the link 19 to the fixed stud 20 and a slot 21 is made in the end of
the crank 15 to allow sufficient play between the rod and the crank pin 22 to allow
the parts to work. The crank is preferably not rigidly fixed to the shaft D⁹ but
carries a pawl 24 engaging a notch or tooth 25 rigidly fixed to the shaft. This
enables the shaft to be very readily stopped when required. The pawl is mounted
upon a stud 26 having a flat side 27 against which an internal spring pin 28
bears and tends to bring the pawl back into position to engage the notch 25 if it
is not moved too far away.
To stop the tape roller F intermittently I drive its pinion 30 by means of the
wheel 31 having a blank space 32 without teeth, and to hold the pinion stationary

page_text: and to retain it in position for the teeth to engage again I employ a con-
centric swell 33 on the wheel 31 to engage the check piece 34 fixed on the side
of the pinion.
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. A feathering stroker consisting of an inclined finger pivoted to a vibrating
arm and arranged to bear on the top sheet when moving towards the feed roller
and to be more or less raised from contact with such sheet whilst moving in the
reverse direction, substantially as hercin shown and described.
2. The combination with the cam shaft 18 of the rod 16 connected to the feed
mechanism and the link 19, arranged and operating substantially as herein shown
and described.
3. The combination with the crank arm 15 loosely mounted upon the shaft D'
of the pawl 24 adapted to engage a projection rigidly fixed on the shaft,
substantially as herein shown and described.
4. The wheel 31 having a number of teeth or their equivalent cut away and
having a concentric piece 33, in combination with the check piece 34 on the roller
pinion 30, substantially as herein shown and described.
