substances.
We, GEORGE STABER and HARTWELL ABBEY, of 360 Clinton Street,
Brooklyn, in the County of Kings, and State of New York, United States of
America, Gentlemen, do hereby declare the nature of this invention to be as
follows:-
Our invention has relation to improvements in machines for embossing wood and
other substances for the purpose of ornamenting the surface thereof, and it has for
its general object to provide means for quickly and conveniently adjusting the
pressure roll with respect to the design roller; for regulating the force of the
pressure spring, and for increasing or diminishing the pressure of the pressure roll
against the stock.
The main frame of our machine comprises a fixed base and uprights or standards
arranged in two pairs, one pair being on each side of the machine. These standards
have adjacent to their upper ends suitable bearings for the trunnions of the design
or die roller which is preferably held in position by pivoted cap pieces whereby it
will be readily perceived that the said roll may be readily removed from its
bearings when it is desired to change the design band or for any other purposes.
Fixed upon one of the trunnions of the roll is a gear wheel with which gears a
pinion on a transverse shaft which also carries a large gear wheel. The latter
gears with an iller pinion loosely mounted upon a lateral shaft and is formed
integral with or is fixed to a large gear wheel also fixedly mounted on the shaft,
said large gear wheel gearing with a pinion on a drive shaft through the medium of
which the design roll is rotated by any suitable motor.
Between the standards of the main frame are vertically disposed end bars of a
yoke-shaped and vertically movable frame, in which end bars are journalled
trunnions of pressure rolls, and suitably connected to said bars are similar side bars
of a table for the stock, designed to extend on opposite sides of the machine and
which will adapt itself to the upper surface of the pressure roll by moving with the
latter, and being sustained alike under yielding pressure, will accommodate itself to
the thickness of the stock.
This table for the stock is provided with a laterally adjustable gauge by means
of which the stock may be guided between the die roll and the pressure roll.
In the centre of the bridge or cross. bar of the adjustable frame before mentioned,
we provide a vertical aperture through which passes the upper end of a vertical
lifting rod or bar. This bar, the upper portion of which is screw-threaded takes
loosely through the hole in said frame and the lower end of the bar is passed
through a hole in the base of the frame through which it is adapted to move
vertically, the rod having a groove into which takes a spline fixed in the hole of
the base to prevent said rod from turning as a screw.

Improvements in Machines for Embossing Wood and other
substances.
GEORGE STABER and HARTWELL ABBEY of 360 Clinton Street Brooklyn,
County of Kings, New York, U.S.A.
Our invention has relation to improvements in machines for embossing wood and
other substances for the purpose of ornamenting the surface thereof, and it has for
its object to provide means for quickly and conveniently adjusting the pressure roll
with respect to the design roller for regulating the tension or the pressure spring
and for increasing or diminishing the pressure of the pressure roll against the
stock.
With the foregoing ends in view, the invention will be fully understood from the
following description and claims when taken in connection with the accompanying
drawings in which
Fig. 1 is a front elevation of our improved machine and
Fig. 2 is a side elevation of the same.
Referring by letter.to said drawing A indicates the main frame of our improved
machine, which comprises the fixed base a and the uprights or standards & arranged
in two pairs one pair being on each side of the machine.
These standards b are. provided adjacent to their upper ends with suitable
bearings as c for the trunnions d of the design or die roller B, which is preferably
held in position by the pivotted cap pieces C, whereby it will be readily perceived
that the said roll may be readily removed from its bearings when it is desired to
change the design band B' or for any other purposes.
Fixed upon one of the trunnions d of the roll B is a gear wheel e with which
meshes a pinion upon one end of the transverse shaft g which is provided at its
opposite end with a large gear wheel h. This large gear wheel / méshes with an
idler pinion which is loosely mounted upon a lateral shaft j and is formed integral
with or is fixed to a large gear wheel &, also loosely mounted on the shaft j which
wheel meshes with a pinion on the drive shaft m through the medium of which
the roll B is rotated by any suitable motor.
Mounted between the standards of the main frame. A, are the vertically-
disposed end bars n of the approximately yoked shape and vertically-movable
frame F, in which end bars are journalled the trunnions of the pressure roll G and
suitably connected to the said end bars n are the similar side bars H of the
or table for the stock, which is designed to extend on opposite sides of the machine
support
and which being secured with respect to the frame F will adapt itself to the upper
surface of the pressure roll G by moving with the latter, and being sustained alike
under yielding pressure will accommodate itself to the thickness of the stock.
This support or table for the stock is provided as better illustrated in Fig. 1 of
the drawings, with a laterally-adjustable gauge I, by means of which the stock
be guided between the die roll A and the pressure roll G.
may
In the centre of the bridge or cross-bar g of the adjustable frame F, we provide
a vertical aperture (not illustrated) through which passes the upper end of the
vertical lifting rod or bar J. arranged in about the vertical centre of the machine.
This lifting rod or bar J the upper portion of which is screw-threaded as illustrated
takes loosely through the hole in the frame F, and the lower end of the rod

page_text: or bar is passed through a hole in the base of the frame through which it is
adapted to move vertically the rod having a groove as shown into which takes.
a spline fixed in the hole of the base, whereby the said rol may be prevented
from turning as a screw.
Kindicates a horizontally-disposed bevelled gear wheel, which is provided with
a central vertical screw-threaded aperture for the passage of the lifting rod J and
is designed to be rotated to raise and lower the frame F, and the pressure roll G.;
and M indicates a nut which is provided with a central vertical screw-threaded
aperture for the passage of the lifting rod J and is designed to be lowered and.
raised to increase and diminish the tension of the spring L, which surrounds the.
bar or rod J, and bears at one end against the fixed base of the main frame
and at its opposite end against the nut M. This nut M, as illustrated is preferably
of an inverted cup shape so that it will surround the upper end of the spring and
prevent the same from spreading. The said nut M is prevented from casua
movement by a check nut which is mounted upon the lifting bar or rod above the
nut. M, as better shown in Fig. 2 of the drawing.
Journalled in one of the end bars n of the frame F is a shaft at which is provided
at its inner end with a bevelled pinion in mesh with the wheel K and is provided
at its outer end with the hand wheel through the medium of which it may be
readily rotated to rotate the wheel K.
By the construction thus far described it will be readily perceived that the tension.
of the pressure spring can be quickly regulated by turning the nut M. and the check
nut the said nut M being lowered on the rod J if it is desired to compress the
spring and increase the tension, or raised when it is desired to expand the spring.
and reduce the pressure of the roller G against the stock.
The height of the frame F and the pressure roll G can be quickly varied by
turning the hand wheel e in the desired direction to raise or lower said frame and
the pressure roll according to the size of the stock to be fed.
It will be further perceived that if the wheel K be moved upward after the
stock is clamped between the pressure roller and the die roller, the lifting rod or
bar J will be forced downward, the spring L will be compressed, and the pressure
of the roller ( against the stock will be increased or in other words after the stock
is clamped, the roller G has no further upward movement so that a continued
rotation of the wheel K will serve to force the bar downwardly which movement
of the bar will compress the spring for the purpose stated.
Although we have in some respects specifically described the construction and
relative arrangement of the several elements of our improved machine we do not.
desire to be confined to the same as such changes or modifications may be made
as fairly fall within the scope of our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that.
