PROVISIONAL SPECIFICATION.
Improvements in Printing Machines.
I, SAMUEL BARNES of Clifton-with-Norwood, near Otley, in the County of
York, Iron Turner, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to facilitate the removal of the flyer used in
printing machines, for taking the paper from the cylinder, when not required, and
bringing it again into position when required.
I employ a circular balance disc to which a weight is attached on one side, and
the opposite side of the balance is attached to a lever connected to the upright rod
carrying the flyer, the balance disc is suspended by a stud having an antifriction
bowl, which works within slots provided in the disc.
On moving the disc around, it lifts the rod upon which the flyer is fixed out of
the way, at the same time it is balanced, on moving it the opposite way in the slot,
it brings the flyer into position again.
Or in lieu of the lever and weight, a chain and weight may be used, the chain
passing around the periphery of the disc to the rod or shaft to which the flyer is
attached, acts in a similar manner as before described.

Improvements in Printing Machines.
I, SAMUEL BARNES, of Clifton-with-Norwood, near Otley, in the County of
York, Iron Turner, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained

DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation showing my invention applied.
Fig. 2 is a front view of Fig. 1.
I employ a circular balance disc A, upon the periphery of which a weight B is
attached, in any suitable position, and at one side of the balance disc is attached a
lever C, connected to the upright rod or slide D, carrying the flyer E. The balance
disc is suspended by a stud F, having an antifriction bowl F, which works within a
slot G, provided in the disc A.
Upon the upright rod or slide D is a bracket D', in which is placed a vertical
rod H, carrying a spiral spring H₁; this rod rests upon a second bracket H* upon
the machine frame, the spring H₁ acts as a balance to the disc A by means of
the bracket D (upon the slide D) bearing upon the saine.
On wishing to raise the flyer, the slid is raised (by means of a handle D upon
the same) at the same time partly revolving or moving the disc upon the anti-
friction bowl, which by means of the weight B, and action of the spring H'upon the
bracket D' lifts the flyer into any position required; on moving the disc the

page_text: opposite way in the slot G, it brings the flyer into position again, the weight of
the flyer depressing the spring and keeps same perfectly balanced.
Or I may dispense with the spring and employ an adjustable balance weight K
shown in dotted lines, upon a screwed spindle attached to the bottom of the disc.
this weight is adjustable upon the spindle by means of nuts K³, and is to regulate
the balance of the disc, am in place of fixing the balance weight B upon the
periphery of the disc I attach same to one side of the disc, this arrangement works
and has the same effect upon the flyer as before described.
Or in lieu of the upright rod or slide, a chain and weight may be used, the chain
passing around the periphery of the disc to the rod or shaft to which the flyer is
attached, this arrangement has the same effect as before described.
Flaving now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use and employment in printing machines of a balance disc with adjust-
able balance weight, lever and spring, actuated by the slide carrying the flyer, as
and for the purposes such as shown and described.
2. The use and employment in printing machines of a balance dise, with adjust-
able balance weight, weight and lever, actuated by the slide carrying the flyer, as
and for the purposes, such as shown and described.
