Improvements in Gearing for Connecting the Rolls of Wood Planing
Machines, Wringers, and other Machines.
1, JOSEPH NAITHON WISE, of Norwalk in the County of Huron, and State of Ohio
one of the United States of America, Organ Maker, do hereby declare the nature
of my invention, and in what manner the same is to he performed, to be particularly
described and ascertained in and by the following statement:
My invention has relation to improvements in expansion gear for use on wood
planers, wringers, and all other machines wherein a system of feed rolls is employed;
and it consists in certain details of construction and arrangements of the parts
composing the same, as and for the purposes as will be hereinafter more fully
explained and from the subject matter of the annexed claims.
The object of this invention is to provide a simple and effective means whereby
the mechanism employed to communicate movement from the lower roll to the
upper roll in rolling mills, wringers, planers &c., is supported and held in proper
position relatively to said rolls, that while they will at all times be in positive
connection, yet said rolls will be permitted to adapt themselves to articles passing
between them.
In carrying out my invention, I proceed as follows, reference being had to the
accompanying drawings forming part hereof where
Figs. 1 and 2 are views in side elevation of a portion of two feed rolls having
expansion gear arranged according to my invention, and
Fig. 3 is a plan and Fig. 4 an end elevation of the same.
In figs. 1 and 3 sprocket wheels and chain connection are employed between the
shaft of lower roll and intermediate shaft while in figs. 2 and
gear connection is
used, otherwise the parts shown in the several figures of the drawings are the
same.
The letters A, B, indicate the rolls and a, b, the shafts thereof. In Figs. 1 and 3,
upon the driving shaft a is keyed a sprocket wheel C and upon the shaft is keyed
a gear wheel D. E is a short intermediate shaft situated slightly above and to one
side of the top shaft band so held by four yokes, two of which as at 1-1 extend
from the lower shaft a and the other two 2-2 extending from the top shaft b.
Upon this shaft E is keyed a sprocket wheel C that is connected by chain F with the
sprocket wheel C on shaft a and a gear wheel 11 that meshes with the gear wheel D
on the top shaft b. Movement being imparted to the shaft a will therefore be
communicated to the shaft through the instrumentalities of sprocket wheels C, C¹
chain shaft E and gears D, D₁ and by reason of the intermediate shaft E being
suspended by the yokes or brackets 1-1, and 2-2 the top roll will have a vertical
movement and continue in positive connection with the driving shaft so that said
rolls will adjust themselves to articles of various thicknesses that may be introduced
between them. The two brackets 1-1 that extend from the intermediate shaft to
the shaft of the lower roll support said intermediate shaft in its elevated position
while the brackets 2, 2 hold the intermediate shaft in its proper position relative to
the shaft of the top roll.
Instead of the sprocket wheels and chain for connecting the drive shaft with the
top shaft as shown in figs. 1 and 3 pulleys with band, belt or cable may be substi-
tuted therefor, or as shown in figs. 2 and 4 cog wheels may be placed on the drive
shaft a and intermediate shaft E as at H and I instead of the sprocket wheels C, C,
shown in figs. 1 and 3, which cog wheels are connected by an idler J on shaft j, thai
has its bearings in the brackets 1-1 whereby movement from the drive shaft will be
imparted to the intermediate shaft and through it to the shaft of the top roll, the same
as were the sprocket wheels and chain employed.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claini is:
The combination with the shaft a of the stationary roll A and shaft 6 of movable
roll B, of the short intermediate shaft E, gear wheel D on shaft b, gear wheel D¹ on
intermediate.shaft E, brackets 1, 1, extending from the extremities of intermediate
shaft E to the shaft a, brackets 2, 2, extending from intermediate shaft E to shaft b
adjacent the gear wheels D, D₁, and means substantially such as described, for
communicating direct movement from shaft a to intermediate shaft E, for the purposes
specified.
