Improvements in or connected with Printing Machines.
We, CHARLES POLLARD and GEORGE BRAYSHAW, both of the Firm of
George Mann and Company, of Elland Road Works, Leeds, in the County of
York, Printing Machine Manufacturers, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to construct apparatus whereby the delivery
mechanism of printing machines can be more easily lifted away from the
impression cylinder in order that free access to the parts may be obtained when
"making ready," or when it is required to take the sheets off by hand, or for other
purposes requiring the removal of the "flyer" and "grid."
According to our invention we employ two vertical uprights, one on each side.of
the machine, the upper portion of such uprights being arranged so as to slide freely
in suitable guides situated on the framework. On the upper ends of these uprights
we mount the frame carrying the "flyer," "grid," and other parts of the delivery
mechanism; and we may also provide suitable pin holes and pins, or other
clamping device for fastening the said uprights in any desired position.
The lower portions of the vertical uprights are constructed with rack edges on
one side, whilst the other edges have.a smooth surface, and suitable brackets are
provided on the framework for guiding the said uprights in their up and down
movements.
A short shaft is mounted in suitable bearings in front of each of the vertical
uprights, and a spur pinion which is mounted on ench of the said shafts gears with
the racks on the uprights.
The weight of the delivery mechanism is counterbalanced by means of suitable
weighted racks, which gear with the said short shafts in such a manner as to tend
to move the uprights in an upward direction, or the weight of the said delivery
mechanism may be counterbalanced by springs or other equivalent means.
The short shafts on each side of the machine are connected together through the
medium of a shaft running across the machine, which cross shaft is geared with the
aforesaid short shafts by means of suitable chain or other gearing.
By having, the counterbalance weights and other parts of the raising mechanism
in duplicate as above described, the delivery mechanism is equally balanced on
each side of the machine, consequently such delivery mechanisin can be raised or
lowered at will in an even aud steady manner.
The raising or lowering operation may be performed by turning a handle on one
of the short shafts, and it will be readily understood that by the employment of
apparatus as above described, the delivery mechanism may be easily and quickly
raised away from the impression cylinder to any required heiglit, such height
depending upon the length of the uprights, which length may be prolonged an
desired to suit requirements.

We, CHARLES POLLARD and GEORGE BRAYSHAW, both of the Firm of
George Mann and Company, of Elland Road Works, Leeds, in the County of
York, Printing Machine Manufacturers, 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:-
The object of our invention is to construct apparatus for raising the delivery
mechanism away from the impression cylinder, when access is required to be given
to the parts for the purpose of "making ready," or when it is required to take the
sheets off by hand, whilst at the same time the said delivery mechanism may be
readily returned to its normal position when it is required for use.
In order that our invention may be clearly understood, we will proceed to
describe same with reference to the accompanying drawings, in which similar
letters refer to like parts in all the figures.
Figure 1. is a side elevation of a portion of the machine with the delivery
mechanism in the down position; and Figure 2 is a side elevation of the same,
with the delivery mechanism raised away from the impression cylinder.
Figure 3 is a sectional plan of the machine, showing the raising and lowering
mechanism.
According to our invention we employ two uprights A, A, one on each side of
the machine, the said uprights being arranged to slide in guides B, situated on the
frame C of the machine. On the upper ends of the uprights A, A, we mount the
frame D carrying the flyer, grid, and other parts of the delivery mechanism; and
we may also provide suitable pin holes and pins, or other clamping device for
fastening the said uprights in any desired position. E, E, are racks, which are
formed on the edges of the uprights A, A, the opposite edges of the said_uprights
having a smooth surface for bearing against the guides B. Shafts F, F, are
mounted in bearings F, FL, and spur pinions G, G, are mounted on each of the said
shafts and gear with the racks E, E, on the uprights. H, H, are weights which
slide in bearings J, J, and the said weights H, H, are provided with rack faces K, K,
which gear with spur wheels L, L, situated on the shafts F, F. The shafts F, F,
are geared together by chain gearing M, M, and shaft N, thereby causing the said
shafts to move simultaneously; and a handle P is provided for the purpose of
actuating the shaft F.
The position of the weights on the opposite side of the shafts F, F, causes the
uprights A, A, and the delivery mechanism to be counterbalanced, so that on the
handle P being turned, motion is transmitted through the chain gearing M and
shaft N to the shaft F on the opposite side of the machine, thus causing the two
shafts F, F, to move simultaneously and thereby raise or lower the delivery
mechanism in an even manner.
The length of the uprights may be increased or reduced according to the amount
of movement required to be given to the frame D, and springs or other equivalent
mechanism may be employed instead of the weights if desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
'
1. The delivery mechanism mounted on uprights A, A, and counterbalanced by
means of weights H, substantially as and for the purposes set forth.
