IMPROVEMENTS IN APPARATUS FOR FEEDING SHEETS OF PAPER, TO PRINTING, RULING, ROLLING, EMBOSSING AND LIQUID COATING MACHINES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I JOHN JAMES ALLEN, of Halifax, in the County of York, Insurance Broker,
do hereby declare the nature of my said invention, for, "IMPROVEMENTS IN
APPARATUS FOR FEEDING SHEETS OF PAPER, TO PRINTING, RULING, ROLLING,
EMBOSSING AND LIQUID COATING MACHINES," to be as follows:-
This invention relates, to further improvements in apparatus for purposes
aforesaid, for which Letters patent No 2638 dated 5th June 1882, were granted
to me, and the object of the present invention is, to secure a uniform, definite,
and predetermined, "amount of pressure, or grip, upon each, and every sheet of
paper, manipulated by the feeding apparatus.
According to this my invention, I employ a fixed or stationary table, or platform,
on which the sheets of paper to be "fed are placed-Above the table, are two
levers, one end of which carries a cross shaft, and disc, covered with india rubber,
and a frame or guide, in which is a self adjusting "retarding pad," the opposite
ends of the said levers, each have a counterbalanced weight, by which the exact
grip, or bite, upon the sheets can be adjusted, to any requirement-In some cases,
in lieu of the disc referred to, an endless strap, or band, passed over stretching
rollers, and having an india rubber pad, or "licker in," may be employed-or
where continuous action is desirable, such strap, or band, may consist wholely
of india rubber.

SPECIFICATION.
I JOHN JAMES ALLEN of Halifax; in the County of York, Insurance Broker,
do hereby declare the nature of my said invention for "IMPROVEMENTS IN
APPARATUS FOR FEEDING SHEETS OF PAPER TO PRINTING RULING, ROLLING,
EMBOSSING, AND LIQUID COATING MACHINES," and in what manner the same
is to be performed, to be particularly described and ascertained in and by
following statement aided by the annexed drawings :-
This invention relates to further improvements in apparatus for purposes
aforesaid for which Letters Patent No 2038, dated 5th June 1882 were granted
to me, and the object of the present invention is, to secure a uniform, definite,
and predetermined amount of pressure, or grip upon each and every sheet of
paper manipulated by the feeding apparatus.
Such being the nature and object of the said invention the following isa
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which :-
Fig. 1. is a side elevation.
Fig. 2. is a plan.
Fig. 3. is an end elevation
Fig. 4. shews endless strap having india rubber pad or "licker in."
Fig. 5. is a plan of part of strap, and "licker in."
At 1. is a stationary, or fixed table on which the sheets of paper 2. to be fod are
placed 3. and 4. are two weighted levers having their fulcrums on the cross shaft 5.
and at 6 is a disc covered with india rubber, and revolving on the shaft Ga driven
by stud wheel, and chain, at 7. 8. are side frames which serve as guides for the
retarding pad 9. faced with india rubber at 10, against the face of which the sheets
of paper 2. rest. Each of the levers 3. 4. is connected with the retarding pad 9. by
means of links 11. and the cross shafts 12. 13. working in the slots of the frames 7. 8.
which serve to ensure true vertical motion of the pad 9. during the descent of the
roller 6. and retarder 9. as the paper decreases in bulk, or thickness. At 14. 15.
are weights by means of which the retarder 9. and the disc 6 and its shaft are
adjusted or counterbalanced. There is also adjustment of the pad 10. provided by
means of the spiral spring 16. and adjusting screw 17 (see Fig. 3.) the said spring
serving to keep the pad close to, and forming a nip with the periphery of the disc 6.
In some cases in lieu of the disc I employ an endless strap 18. having a pad, or
"licker in " 19. of india rubber let into and about flush with the surface of the said
strap. It will be seen that the disc 6. and retarder 9. are by links 11. and their
shafts so connected as to work, and move together, and gradually descend, as the
sheets are removed.

page_text: 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
The combination of the disc wheel 6. retarder 9. connected by links 11. and
operated or moved by means of the counterbalanced levers 3. 4. substantially
as herein described, and illustrated by drawings.
