Specification Accepted, 30th Dec., 1887
We, DANIEL BYRON BURDETT, Mechanic, and JOHN ANDREW LEACH, Capitalist,
both of the city of Minneapolis, County of Hennepin, State of Minnesota, United
States of America, 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 :-
Our invention relates to the ornamentation of wood, leather, paper or other similar
material.
It has for its object to impress ornamental designs of any desired pattern upon
various kinds of wood work, such as finishing and trimming material, wooden ware,
picture-frames, furniture, and all kinds of household articles of use or ornament, and
upon many kinds of work made out of leather or paper.
It consists, primarily, in the coincident application of heat and pressure through
die-rolls containing the desired pattern; and, secondly, in a machine for applying the
process, capable of ornamenting both sides at once, and with die-rolls having lateral
and angular as well as vertical adjustment, whereby the several surfaces of a piece
of material, whatever their angles to each other, may be ornamented and the work be
done simultaneously, if desired. For example, a smooth surface and a raised bead on
the same or the beveled surfaces of a picture-frame may be ornamented by our process
and machine. The die-rolls are also so arranged with reference to each other that
several different patterns may be impressed at the same time, or that a light and heavy
impression may be made simultaneously on the different parts of the same material.
For example, a deep or heavy impression may be made in the middle and light
impressions on the edges, or a heavy impression on one side and a light one on the
other:
Our machine is illustrated in the accompanying drawings, in which, like letters
referring to like parts throughout, Figure 1 is a front elevation. Figure 2 is a side

page_text: elevation; and Figures 3, 4, 5, 6, 7, 8, 9, and 10 are details, viz: Figure 3 is a front
or rear elevation of the central upper pressure-roll and press-frame. Figure 4 is a
similar view of the rear upper die-roll and press-frame or of the under die-roll and
press-frame. Figure 5 is an enlarged view of the vertically-reciprocating roll-carrying
frame shown in Figure 4. Figure 6 is a plan view of Figure 5. Figure 7 is a
sectional view on line X X¹ of figure 5. Figure 8 is a front view, on an enlarged
scale, of a modified form of the adjustable roll shown in figure 1. Figure 9 is a plan
view of figure 8, and figure 10 is a section of figure 8 on the line YY'. Figure 11 is
a vertical transverse sectional view showing the lower die-roll and its supporting
mechanism.
In a general way, the machine may be described as consisting of a main frame, a
bed-plate for holding the material, feed and resistance rollers protruding through the
bed-plate, die-rolls held in vertically-reciprocating blocks, two sets above and one
below the bed-plate, a resistance-roller held in a similar vertically-reciprocating block
directly above the under-side die-roll, screws held in cross-ties of main frame for
giving the requisite pressure, a gas-flame or other suitable means for heating the die-
rolls, and certain details of construction for giving various special adjustments.
AC is the main frame, made of any suitable material, preferably of metal, of which
C is the base, and A the upper part. The two parts are cast separately. A rests upon
and is secured by bolts to the base-frame C. C is provided with suitable cross-
braces, e¹. In the part A are three vertical grooves, a a² all, on the interior face of
each side plate--one near the front one in the rear, and one in the center. The
central part of the upper frame, A, is extended and rests in a cut-away part, c, of the
lower frame C. The central groove, a', extends the entire length of this central
portion, making a groove on the interior faces of the side plates both above and below
the bed-plate D.
Bis the top or cap plate resting on the side plates of part A, extending from front
to rear, and is provided with raised ribs over and on a line with the vertical
grooves a a¹ a. In these ribs are holes b, provided with female screw-threads,
through which work screws m¹ k¹ g', provided with male threads. These screws are
provided with vertical grooves. Hand-wheels g1111 111 m, provided with a feather
fitting in the vertical grooves of the screws, fit over the screws and rest on the ribs of
plate B, for operating the screws.
B is a bottom plate attached to the lower frame, C, provided with a raised rib
under the central vertical groove, a¹, and having a hole with female screw-threads,
through which works screw ². This screw has a vertical groove similar to
screw m², and a hand-wheel, 111, with a feather, fits over the same and rests on
plate B', for operating the screw.
D is a bed-plate fixed between the side plates of frame A, provided with transverse
openings, through which protrude feed and resistance rollers E E. These rollers E E¹
may or may not be corrugated, as desired. The shaft or journals of one of the feed-
rollers are extended outward beyond the frame on both sides of the machine, and on
one side is attached a pulley, f¹, which is connected, by a belt or other suitable means,
with a source of motion, (not shown) and on the other side is attached a sprocket-
wheel, F. A chain, f, connects F with a similar sprocket-wheel, F, attached to
a similar extension on the same side of the journal of roller E'.
In the grooves all of the side plates of A fit tenons gll of block Gg H, of which G
is a cross-bar or spider, with legs extending downward at the ends and in the middle,
and made integral at those points with H.
His a rectangular plate considerably wider than the spider G, and has its central
part in cross-section cut away for its whole length to within a margin of each end.
On the upper surface of the sides of plate H rest cross-bars h¹, to which are attached,
by bolts, journal-bearing plates h, fitting between the interior and against the
under faces of the plate H. The plates h are provided with suitable journal-boxes, in
which, by journals j, is held the die-roll J.
The spider G is provided with a shallow recess or hole, g, serving as a point of

page_text: application for the screw ², and a pin, g, extending into an annular groove in the
screw, serves to keep the two parts connected when the screw is being raised. By
thus attaching the die-roll J through h to cross-plates ¹, it may be moved laterally at
will wherever desired.
The under-side die-roll, T, is attached in exactly the same way to a plate integral
through spider-legs to the spider or cross-bar R. R and its connected plate are
provided with similar tenons fitting into the grooves a' below the bed-plate, and is
connected to and operated by screw in the same way as block Gg H. Roll T
works through opening in D. A block, K, having similar tenons fitting in the
grooves a above the bed-plate D, is attached in a similar manner to screw k¹, and
carries in journal-bearings rigid therewith the resistance-roller L.
In the front of the machine, attached to and rigid with cap-plate B, and on a line
with the grooves a, is a pendent bar, 61, having grooves on its sides similar to a, and
in the same plane therewith.
In the grooves of b¹ and the grooves a fit tenons m¹ of a vertically-reciprocating
block, M.
M is a cross-bar or spider attached to a plate, s, below by spider-legs at the ends
integral with the plate, and is provided with a shallow recess receiving the screw m¹,
and is attached to the screw by a pin, m¹, fitting into an annular groove on the screw.
The lower plate, s, has its central part cut away, as in the case of plate H. To this
plates, by bolts, are attached on the under side the half journal-boxes P, (in figure 1,)
the under side of the plates being recessed to form the other half of the box. In
these boxes rest journals or trunnions integral with a block solid above and bifurcated
below the trunnions, forming a head, n¹ and arms N n.
Between the arms N n and in boxes in the same are journaled the die-rolls Q. The
outside upper surface of the head is cut to the lines of a perfect circle from its
trunnion as a center. The under surface of bar M is cut to the lines of a
corresponding circle from the same center, the concave surface of M fitting exactly
over the convex surface of . This causes the pressure to be equally applied to the
die-roll in whatever position it may be.
The bar M has integral with its front and rear surfaces pendent lips embracing the
head The front lip is provided with a screw-threaded hole, into which fits a set-
screw, o, whereby the head 11 may at will be made rigid in any given angle to the
bed-plate and the material to be ornamented.
n
In the modification shown in figures 8, 9, and 10, the plates P contain the entire
bearing for the trunnions, and are secured by bolts and nuts p, through longitudinal
slots p, to the plate s. The arm n is removably attached by set-screw n¹ to the die-
roll block whereby the die-roll may be removed and another substituted when desired.
By the construction shown in figures 8, 9, and 10 the die-rolls Q may be moved
laterally as well as vertically and at angles to the bed plate. This is our preferred
construction.
Wis a bracket attached to some convenient part of the vertically-reciprocating
block, for holding a gas-burner, w¹, in close proximity to the die-roll. ¹ is a gas-
tube communicating with a reservoir of gas.
Any other suitable means may be used for heating the die-roll, as, for example,
steam my be introduced to the interior of the roll.
In the drawings we have shown means in position for heating one of the rolls.
In
our working machine we heat all the die-rolls. We find this to be a radical improve-
ment on cold rolls. The heat extracts and evaporates the moisture forced out in part
by the pressure, closes the pores, more effectually overcomes the elasticity of the
material, preventing its return to its original position, and leaves a smooth and
finished surface. In other words, the coincident and simultaneous application of heat
and pressure leaves a more permanent and a finer impression. It also enable us to
impress a lighter and more delicate ornament.
The operation of the machine is apparent from the description. Motion having been
imparted to the pulley f¹ from the source of motion, (not shown) the material to be

page_text: ornamented is placed on the bed-plate in the rear of the machine, and is fed forward
by the feed-rollers under the die-rollers, which have been previously set for the desired
pressure and depth of impression. The rear die-roll, J, will impress any desired
ornament on the central part of the upper surfaces. The under die-roll, supported in
block R, will do the like for any part or the whole of the under surface, if desired, and
the die-rolls Q will impress ornaments on the edges of the upper surface. The
designs on the various die-rolls may be similar or different, as desired. A heavy
impression may be given by one or more of the die-rolls and a light impression by the
others.
If the material have raised beads or mouldings, either in the center or on the edges,
these may be ornamented as well as the body of the material by properly adjusting the
die-rolls; and if there be beveled edges, as in picture-frames, the die-rolls may be
set at an angle and these edges be ornamented. The lateral adjustments enable the
machine to ornament wide or narrow, pieces of material, as desired. By varying the
size of the die-rolls a narrow or wide pattern, as desired, may be impressed.
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 what we claim is :-
1. In a machine for ornamenting wood, leather, paper, or other material, the
