PROVISIONAL SPECIFICATION
An Improved Appliance for Self-feeding Apparatus to Printing and
like Machines.
I, WILLIAM BRIDGEWATER, of 301, St Peter's Lane, Leicester, in the County
of Leicester, Engineer, do hereby declair the nature of this invention to be as
follows.-
My invention relates to a construction of apparatus for feeding successively
sheets of paper to pinting folding uling and like machines described in the
Specification to my application for a Patent No 21721 of 1898
In this application I described apparatus for buckling the top sheet of a pile by
means of two rollers My present improvement is a pneumatic collar or rollei
made of rubber or other suitable material, having a serrated periphery To make
certain of buckling one sheet only at a time, one or more of these collars may be
placed on a shaft and used in place of one or both the tollers above mentioned

An Improved Appliance for Self-feeding Apparatus to Printing and
like Machines.
I, WILLIAM BRIDGEWATER, of 301, St Peter's Lane, Leicester, in the County
of Leicester, Engineer and Machinist, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly de-
scribed and ascertamed in and by the following statement
-
This invention has reference to what are known as paper feeding machines
and more particularly to that class of such machines in which the separating and
feeding foi waid of each successive sheet is effected by rollers pressing upon such
sheet to buckle or arch it in the manner well understood, and as described and
illustrated in the Specification of my Patent No 21721 of 1898
The primary object of this invention is to provide means for applying a more
sensitive and resilient pressure than heretofore upon the sheets of paper, so as
to give a hfting tendency to the pressure rollers
To this end the invention consists of forming the pressure rollers with seated
peripheries and in one length or cach roller may consist of a plurality of collais
with serrated periphenes of rubber on other suitable material, such rollers being
more certain and uniform in then operation than the continuous 1ollers on collais
with smooth or ordinary roughened peripheries as hitherto used
Reference is to
be had to the accompanying diawing and to the letters marked thereon forming
a part of this specification
Uf the drawings, Figure 1 represents a perspective view of a hollow or pucumatic

section of same Figure 18 a sectional view of a solid colla hei einattei e-
feiled to
Refering to the diawing, which portrays two forms of collar in accordance with
the invention selected for the purpose of illustration, it will be seen that the
hollow or pneumatic collar (Figures 1 and 2) has a sleeve A extending both sides
of the body B, the inside diameter of the sleeve being such that it will hold in
position on the spindle by reason of its own embracement The periphery of the
colla is seated forming a series of teeth C, the two taces 1) and E of such teeth
difteling in acuteness, the more acute face E facing the direction of travel, sce
allow in Figure 1
With hollow or pneumatic collais (see Figs 1 and 2) the periphery 19 1ounded
as illustrated in the diawing, but with solid collars or sleeves as in Figure 3,
the periphery 18 preferably flat
While I have shown in the diawing and described in this specification the
preferred forms of my invention, one or more of the collars or sleeves constituting
a pressure rolle when mounted upon a spindle, my mention 18 by no means
specifically limited thereto, but is susceptible of further embodiment without
departing therefiom For instance, instead of the body B being made hollow
01 pneumatic it may be formed solid with a flat peuples as before stated and
illustrated in Figure and further a number of the collars may be formed on one
sleeve, either all hollow or pneumatic or all solid or a combination of both, in all
instances however, having serrated peripheries
Furthermore it is to be understood that my invention is applicable to all classes
of machines provided with pressure rollers for separating and feeding sheets of
paper and analogous materials, the hollow or pneumatic collars (Figs 1 and 2)
being specially applicable to the separating rollers and the solid collars (Fig 3)
being applicable for the delivery rollers of such machines
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim 18.-
1
1. In a paper feeding machine a pressure or separating roller comprising a
plurality of hollow or pneumatic collais with serrated and rounded periphenes
mounted on a spindle and adapted to engage successive sheets of paper, substan-
tially as described
2 In a paper feeding machine, in combination, a rear pressure or separating
roller provided with a plurality of hollow or pneumatic collars with seated and
rounded peripheries adapted to sequentially separate each top sheet from a pile
of sheets and a fiont or delivery toller provided with a solid or non-pneumatic
peripherally seated resilient sui face, and adapted to engage and feed successive
sheets of paper substantially as described
3. In a paper feeding machine in combination, a real pressure or separating
iolle provided with a plurality of hollow or pneumatic collars with seriated and
1ounded peripheries and provided with sleeves which clasp the spindle on which
they are mounted, and a fiont or delivery roller having a solid or non-pneumatic
peripherally serrated resilient surface, the serrations on the several parts having
the faces of different acuteness, substantially as described
4. In a paper feeding machine a pressure roller comprising a plurality of hollow
or pneumatic collars provided with sleeves which clasp the spindle on which they
are mounted, the peripheries of said collars being rounded and serrated laterally
the two faces of the serrations of different acuteness, substantially as descubed
