Improvements in Paper Hanging Machines.
I, ADAM HENRY LOHLKER, of 221 East 7th Street, St. Paul, Minnesota,
United States of America, Merchant, 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:-
This invention relates to paper hanging machines and consists in the construction,
combination, and arrangement of parts, as hereinafter shown and described, and
specially pointed out in the claims.
In the drawings,
Fig. 1 is a-side elevation.
Fig. 2 is a sectional side elevation, and
Fig. 3 is a front elevation of the apparatus complete showing its construction
when employed for applying paper to side walls.
Fig. 4 is a sectional detail illustrating the construction of the attachment for
guiding the paper.
Fig. 5 is a cross sectional view on line x, x, of Fig. 1.
Fig. 6 is an enlarged cross sectional detail of the paste applying and trimuming
mechanism, and
Fig. 7 is a plan view of same.
Fig. 8 is a semi-sectional side elevation showing the manner of arranging the
attachment for using the apparatus in applying paper to ceilings.
Fig. 9 is a perspective view of a portion of the ladder step attachment as shown
in Fig. 8.
Fig. 10 is a perspective view of part of the apparatus.
The main framework consists of a base frame 2 supported upon suitable wheels 3
by which it may be moved from place to place, and with two standards 1 rising
from the end which comes farther from the wall to be papered, and connected by
suitable cross braces 7 and with diagonal braces 8, and supporting a vertically
adjustable framework 9, also preferably connected by suitable cross braces, and
adapted to be locked at any desired point of elevation by cam clamps 4 pivoted
at 13 to the inner portions of the braces 8, or the standards 1, and resting by
their curved cam shaped free ends against the edges of the extension portion, as
shown.
Supported across the upper portion of the vertically adjustable framework is a
roller 14 over which the paper-carrying belt 15 runs, as shown.
5 is the paste box in which a revolving brush 16 is mounted, and in which also
a rod 6 is mounted for supporting the roll of paper 17, as shown.
Upon the rod 6 between the end of the roll of paper and the end of the paste
box is a spring 46* which serves the two fold purpose of keeping the roll of paper
in its proper place upon the rod, and also as a tension to prevent the paper unrolling
too easily.
12, 12, are two rollers, preferably of rubber, or with rubber surfaces, suitably
mounted across the framework and the upper one provided with cutting wheels 19,
one at each end, by which the paper is "trimmed" as it passes between the rollers.
Between the revolving brush 16 and the rolls 12, is a wiper strip 18 over which
the paper runs, whereby the surplus paste is wiped off, a tension roller 20 being
suspended above the wiper strip to assist in the process.
A tank 40 is supported upon the framework and arranged to supply the paste by
a section of hose or other form of pine 21, as shown.

page_text: Across the framework about opposite the rollers 12 is another roller 24 for
supporting the carrier belt 15, as shown.
Removably connected by their lower ends to the end of the base frame which
comes next the wall to be papered, is another pair of standards 23, each formed in
two parts and connected by clamps at intervals, as shown in Figs. 3 and 5, so as to
be vertically adjustable like the standards 1, and having a substantially horizontal
framework 22 pivoted to the upper end at 25, and resting across the tops of the
vertically adjustable framework, being held in place thereon adjustably by clips 26
and set screws 27, as shown.
The frame 22 extends beyond the standards 23, and is arranged to support the
paper cutting mechanism 28.
A paper and belt carrying roller 29 is also supported by the frame 22 just in the
rear of the cutting off mechanism 28, as shown.
The revolving brush 16, the rollers 12, and the roller 24, are provided with chain
sheaves, so that one endless chain 30 can be employed to operate them all by one
crank 31 on one of the rollers 12, as shown.
41 represents a bar pivoted centrally at 32 to the frame 22, and over which the
paper passes on its way to the cutting off mechanism 28.
This bar is adapted to be moved upon its pivot to elevate one side of the paper
more than the other, so as to cause it to run at a slight angle, to enable the operator
to properly fit the adjacent edges of the paper when the walls are not true, or
when for any reason the edge of the paper does not come perpendicularly upon
the wall.
-
A drip pan 39 will be arranged beneath the paste box and trimming mechanism,
as shown, to receive any drippings which would otherwise fall upon the floor.
42 represents a small adjustable frame having rollers 33 and adapted to be set to
run along the base boards or lower part of the wall being papered, to keep the
machine at the proper distance therefrom.
Journalled across the ends of the frame 22 outside the roller 29 is a rod 10 having
a serrated blade 28 depending therefrom, and with an arm 11 on one end projecting
downward and backward across the standard 23, upon which it is guided by a
loop 49, and ending in a weight 50. The lower or serrated edge of the plate 28
is held by the weight normally out of contact with the paper, which passes downward
between the roller 29 and the serrated strip 28, as shown.
The arm 11 is so bent as to be struck by the frame 34 as it rises, and thus
throw the arm 11 upward and move the serrated plate 28 inward to cut off the
paper.
When thus arranged, the end of the paper will be carried through the rollers 12
and beneath the rear roller 24 and upward over the other rollers 14, 29, and down
in front of the cutting off' mechanism 28.
The crank is turned until the end of the paper has fallen to the proper point,
when the operator presses the end against the wall at the upper edge of the
base board, at the same time matching the figure, if any, with the paper previously
hung. When attached at this point the smoothing device is operated and the paper
cut off.
The smoothing device is adapted to be moved vertically upon the standards 23
by a spring roller 43.
Supported by brackets 44 upon the sliding frame 34, is a wire loop frame_45,
supporting a circular brush 46, the loop frame being free to be turned upward, as
in Fig. 8, but prevented from moving below a certain point by a stop 47 resting
against the lower part of the frame 34.
The brackets 44 are set at less distances apart than the length of the loop
frame 45, so that the latter carrying the brush 46 may be moved laterally in the
brackets to adjust the brush across the width of the paper, so as to properly reach
every part.
When the apparatus is to be employed for papering ceilings, the set screws 27
holding the frame 22 to the part 9, are released, and the lower ends of the

page_text: standards 23 disconnected from the base frame 2, and the frames 23 and 22 moved
backward as shown in Fig. 8, so as to permit the insertion in its place of a ladder
like frame 36, as shown.
Resting across one of the rounds of this ladder frame is a step 35 with its inner
end supported by clips 38 to one of the cross braces 7 of the standard's 1, and also
provided with an adjustable cross bar 37 having its ends resting behind the sides of
the ladder frame, as shown.
By this simple means an adjustable step is formed for the operator, from
which he receives the paper already pasted and trimmed, and applies it to the
ceiling.
The carrying belt 15 will be made with a
when the ceiling attachment is employed.
"
"take up so that it can be shortened.
