COMPLETE SPECIFICATION.
A Registering Frame for Laying on the Sheets in an Exact Manner in
a Lithographic or Color Printing Hand Printing Press.
I, WILHELM SABEL, of Entenpfuhl Strasse No. 4, Coblenz, in the Empire of
Germany, Geometrician, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
In the present state of the art when producing prints in several colors by
means of a lithographic and printing press, the entire success depends principally
on making a good register. To this end the fitting of prints into the hand
printing press is done by means of dotting needles, which put through marked
holes in the paper and then into corresponding or registering holes in the stones
serve to assist in laying on the paper correctly. But even the difference of
measure between the points of the needles and the shafts, and still more the
enlargement of the holes in the paper and stones in consequence of frequent use,
and in addition the inaccuracies in sticking through the paper are all sources
of faults, which produce a great number of imperfect and mutilated sheets;
without taking into account that this process is very tedious and consumes much
time and especially if great sizes are in question cannot be performed by one
printer alone without aid.
However by employing my improved frame, a printer even of limited experience
can print the greatest sizes alone without assistance and in less time than
hitherto required; foul impressions are totally excluded, and differences arising
from the paper shifting while printing can be obviated.
My new frame is intimately fitted to a stone and an accurate register can be
obtained by means of markers or indicators which can be successively put on or
taken off. After drawing or engraving the desired pattern on the stone a limita-
tion line for the printing paper is similarly marked thereon by a long side line
and also an adjacent end line conforming to the shape of the paper as will be seen
from the drawings. These limitation lines are likewise marked on every other
stone used in impressing the various colors on the paper and which stones are
prepared in any well known manner. Therefore if all the stones employed have
the same laying on frame, carrying marks in equal positions, a good register must
necessarily be obtained.
In the accompanying drawings which form a part of this specification and in
which similar letters refer to similar parts:-
Fig. 1, is a plan view of my invention showing it in connection with a stone.
Fig. 2, is a sectional view of Fig. 1 on line x-x.
Fig 3, is a plan view of my frame with markers attached.

page_text: Fig. 4, is a sectional view of Fig. 3 on line y-y.
Fig. 5, is a side view of the marker, or indicator I employ (on an enlarged
scale).
Fig. 6, is a view on line of Fig. 5.
In the drawings it will be seen I have shown one of the stones A furnished
with the color Z. My laying on frame. consists of an angle iron B which is
preferably constructed in the relative proportion and placed against the stone
as shown. Secured to the inner face of the long leg of said angle iron are a
plurality of wooden blocks b which when the frame is in position rest against
the side of the stone and serve when the frame is fastened to give the same a
better hold. The inner face of the short leg is similarly provided. Formed in the
outer end of the said long leg are a plurality of transversely extending horizontal
holes through which a bolt d is adapted to pass and engage an adjustable
block D which has on its outer end a hook d. The free end of the short leg of
frame B is provided with a foot having an opening therein through which I
pass the screw-threaded shank of a hook E. Connecting the two hooks and pass-
ing around the free side of stone A, is an endless preferably wire rope, which,
when the nut working on the shank of hook E is tightened, draws the frame
tightly against the said stone A and retains it in that position. Mounted in the
block aforesaid is a clamping screw d', which, working against a block 63
bearing on stone A, serves to also hold the frame in its position against the said
stone.
In order to ensure that the markers or indicators hereinafter described, shall
be placed in their exact and correct positions, the accurate adjustment of the
frame B to the stone A. must be obtained To do this, I form in both legs of the
Each of
frame a plurality of threaded openings adapted to receive screws t.
these screws pass through and clamp to the frame, a guiding arm C. The under
surfaces of these arms are preferably flat, and when they are fixed on the frame,
and the two flat surfaces are made to engage truly, the frame and stone will lie
in the same plane, or in two planes parallel the one to the other. The frame
can now be firmly secured to the stone by means of the endless wire rope above
mentioned. The clamps C are then taken off and the markers or indicators F
(Figs. 3, 4, 5 and 6) substituted.
Each of these indicators (see Figs. 5 and 6), are preferably formed of a block h
through which are passed two parallel rods h¹. Sliding freely on these rods and
to the left of said block h is a tail-piece i having on its lower surface pointed legs f
adapted to snugly fit in openings provided in the angle frame B. In the
adapted to press against the
upper part of the tail piece are clamping screws
rods g. It will be thus seen that when the indicators are set in position, the
screws are loosened and the head plate (hereinafter described) placed approxi-
mately in proper position, after which said screws are tightened. On the
other end of said rods is a head-piece K also freely mounted and provided in its
centre with a screw threaded opening. Mounted in the block h is an adjusting
thumb_screw K2 which passing through the said threaded opening in the head-
piece K allows a fine adjustment of the latter. Surrounding the said screw K
is a spring which bears continuously against the said head-piece and assists in
securing an exact adjustment thereof. In each end of said head-piece K are
other set screws K¹ which, when the head-piece K has been properly and
accurately adjusted so that the nose M registers exactly with the limitation line
aforesaid, are tightened thus holding the said nose continuously in its exactly
correct position.
In practice I have found that three markers (two on the long side and one
on the short) are all that are necessary. The markers being in position the
paper is laid on so that its long edge rests against the two markers and its short
edge (or left end) against the single marker. The markers are next removed
and the press operated, the papers securing the impression exactly where desired,

excluded.
