Improved Pantographic or similar Apparatus.
I, SEBASTIAN PUTZ, of Sinnthalhof, near Brückenau, Rhön, in the Empire of
Germany, Sculptor, do hereby declare the nature of this invention to be as
follows:-
This invention consists in an apparatus which may be used in reproducing
modelled or flat objects either on the same or on different scale and either in
the same relative position of the parts or reversed left for right.
It consists of a base plate or member which may be referred to hereinafter as
horizontal, though it may be fixed to lie in any plane. On this member on a
vertical axis turns another member and on the latter on a horizontal axis there
turns a third member having guides in which slides a prismatic tube forming a
fourth member the sliding axis of which traverses the horizontal axis of the
third member at right angles. The end of the fourth member carries in a
universal bearing a sliding pin the axis of which contains the centre of the sphere
of rotation of said universal bearing.
On the first member is an adjustable abutment and on the second member two
separately adjustable arms, the other members have means for fixing them in
any position given to them each respectively on the member which supports it
and the sliding tube may have a scale or suitable means for measuring its move-
ments.
By suitable adjustment of the arms and abutments the apparatus swung in one
direction till one arm touches the abutment and then adjusted with the pin on a
particular spot of the model may be swung until the other arm touches the abut-
ment to indicate the corresponding spot of the replica.
Movement of the sliding parts would give a corresponding enlarged or reduced
replica.

I, SEBASTIAN PUTZ, of Sinnthalhof, near Brückenau, Rhön, in the Empire of
Germany, Scalptor, 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:-

page_text: for the use of seulptors; and has for its object to produce an instrument which
can be so adjusted or arranged that any desired spot on the work or model can
be located with only one reading of the instrument. The invention consists in
the improved construction and combination of parts of the same as will be herein-
after more fully set forth.
In the accompanying drawings, in which the same reference numeral indicates
a corresponding part in each of the views in which it occurs,
Figure 1 is a front elevation of an instrument embodying my invention;
Figure 2 is an end elevation, the staff or pencil and its support being shown
detached and at one side of the instrument, the instrument being shown detached
from its base or support in both figures.
Figure 3 is a vertical sectional view of the instrument showing the base in
position and the clamps on the bottom of the instrument shown at right angles
to the position they occupy in Fig. 1.
Figure 4 is a broken top plan view of the bottom of the instrument and the
base;
Figure 5 is a perspective view of the clamps at the bottom of the instrument,
and
Figure 6 shows diagrammatic views of the manner in which the instrument
can be used.
Referring more particularly to the drawings, I indicates the main frame of my
improved instrument, and 2 indicates one form of base upon which it may be
supported. The base is preferably circular and recessed as shown at 3, and pro-
vided with a laterally projecting annular flange 4 upon which a movable stop 5
is adjustably secured, as by means of a set screw 6.
In using my invention, it is sometimes necessary to use two bases, one located
near each object, as where the model is located at a distance from the work, in
which case it is necessary to move the main portion of the instrument from the
one to the other after it has been adjusted. Ünder these circumstances the base
may not have the exact form shown in the drawings, but have only the tapering
portion 7 to fit within the conical recess S of the main frame.
The frame is provided with a circular bottom 9 which fits within the recessed
portion of the base and has its top surface even with the top surface of the base,
and has its periphery recessed or undercut so as to form a flange 10. Pivotally
secured to the cylindrical stem 11 of the main frame are two arms 12 and 13, one
of which rests flat upon the bottom 9 and the other one is bent so that its inner
end will rest upon the inner end of the other arm and its outer portion will rest
upon the upper surface of the bottom. The outer end of each of the arms extends
beyond the bottom and rests on top of the flange 4 on the base, and has a down-
wardly extending hook 14 which fits under the flange 10 and is clamped against
it, as by a set screw 15. One of the arms 13 is preferably provided with a seg-
ment or sector 16, which is adapted to be held against the top of the other arm
by a clamp 17 and set screw 18. The clamp is held in position by the screw 15
which passes down through it and into the arm 12.
The upper portion 19 of the main frame or standard is at one side of the stem
and is provided with a segment or sector 20, which is preferably secured at its
ends thereto by means of screws or bolts, although it is evident that it could be
formed integral therewith if desired. Pivotally secured to the standard at the
centre of the segment is a vertically movable arm 21, each end of which is
provided with an eye or bracket 22 through which passes a rod 23. The eyes and
the rod are preferably prismatic, as for instance, triangular, and the centre of the
rod is located directly above the centre of the base and directly opposite the
centre of rotation of the arm, so that all measurements will be taken as from one
fixed point. The rod is held against longitudinal movement by a clamp com-
prising a rod 24 extending from one eye to the other and having one or both of its
ends forced against the rod by a cam lever 25 that is pivotally secured to a pro-
jection 26 on the side of the arm 21. The position of the arm relatively to the

page_text: standard is regulated by means of a lug 27 which engages with an adjustable
clamp or stop 28 on the segment 20.
At the outer end of the rod 23, a stem 29 is rotatably secured as by having its
inner end fitted within a recess in the rod as shown in dotted lines at 30 in Fig. 1.
The stem can be locked against rotation by any suitable means, as a clamp, or by
friction. To the outer end of the stem a plate 31 is pivotally secured by means
of a screw 32, each end of the plate being provided with a perforated bracket 33.
A longitudinally movable pencil or pointer 34 is secured within said brackets by
means of two collars 35 and 36, one above and one below the brackets. The
centre of the pencil is located directly in the axial line of the rod 23 and the screw
is located in the horizontal plane of the rod directly opposite the centre of the
pencil, so that all the movements of the point of the pencil will be taken from a
point having a certain fixed relation to the axis of the rod 23 and a lateral move:
ment toward or from the point of movement upon the standard.
In practising my invention, if it is desired to make a reproduction upon the
same scale, the model and work are put at equal distances from the centre of
motion on the standard and at the same height. The angle is then determined
at which the two figures stand with relation to the centre of motion on the
standard and the instrument is turned until the point of the pin 34 will lie in a
vertical plane of the model. The stop 5 on the base and one of the arms as 12
are then rigidly secured so as to be in contact with each other. The remaining
arm 13 is then rigidly secured on the opposite side of the stop 5 at a point equal
to the angle at which the model and work are located in relation to the point of
movement on the standard. With the parts thus arranged the point of the pencil
is placed in contact with any point upon the model which it is desired to reproduce
and secured in fixed relation to the rod 23 and standard 1. The entire instrument
is then rotated upon the base until the arm 13 strikes against the stop 5 which
will cause the point of the pencil to indicate the location of the desired spot upon
the work.
If it is desired to enlarge the work, as for instance, two fold, the model is
located as near the apparatus as possible and the work is placed twice as far from
the centre of movement on the standard as the model. The position of the
model and the work are so chosen that two supposed straight lines through the
centre of motion on the standard and two corresponding points on the model and
work, respectively, will form equal angles with the stop upon the base. The
collars 35 and 36 upon the pin 34 are so arranged that when the collar 36 is in
engagement with the bracket 33 the point of the pin is just half the distance from
the centre of movement of the pin as when the collar 35 bears against the bracket
at the opposite end of the plate 31. The point of the pin is then placed upon
the point of the model to be reproduced while the collar 36 rests against its
collar, and the location of the rod 23 relatively to the centre of movement on the
standard is noted in any desired manner as by a scale or graduation marks on
the rod. The instrument is then turned horizontally as far as the arms 12 or 13
will let it go, and the rod is drawn through the brackets 22 until it projects just
twice as far as it did and the pin 34 is pushed through the brackets 33 until the
collar 35 is in engagement with its collar 33. In this position the point of the
pin 34 will indicate the position upon the work which it was desired to determine.
If a different ratio of enlargement is desired the collars 35 and 36 are adjust-
ably secured upon the pin 34 in the desired position relatively to the collars 33
and the distance to which the rod 23 is to be moved is indicated preferably by a
suitable scale which may be secured thereto.
When it is not convenient to locate the model and work sufficiently close
together as to use the instrument upon the same base, two bases may be used, one
near each, and so arranged that after the instrument has been adjusted upon one
of the bases it may be moved bodily to the other one and the measurements made
in the same manner as though the instrument were used upon the same base.

page_text: The
If it be desired to reverse from right to left in the same size, a stop 37 is adjust-
ably secured to bottom of the standard similar to the manner in which the armis 12
and 13 are secured and said arms (which are not fastened to the flange 10 of the
standard) are swung around until they engage with the opposite sides of said
stop and also with the stop 5, as shown in full lines in position 1 of Fig. 6.
standard is then rotated upon the base until the rod 23, or the pin 34 carried
thereby, reaches the desired point to be reversed. During this movement one of
the arms, as 13, has remained stationary in contact with the stop 5, and the
stop 37 has remained in contact with the arm 12 and has carried it into the position
as shown in position II in Figure fi. The segment 16 is then clamped against
the arm 12 by the set screw IS which will bind the two arms together similar
to a pair of compasses or dividers. The arm 12 is then moved back into its
original position against the side of the stop 5 which will carry the other arm 13
as far from the stop as the arm 12 was when the screw 18 was set against the
segment 16. In this position the rod 23 will have been moved just half as far
as it is desirable to have it move. To complete its movement the standard is
further rotated on its base until the stop 37 comes in contact with the arm 13,
as shown in position III in Fig. 6.
By rotating the stem 29 within the rod 23 so as to throw the point of the
pencil as far upon the opposite side of a vertical line as it occupied when the
arms and stops were being adjusted the desired point which was to be reversed
will be found.
The ratio of change or variation between the two points being determined can
be varied by the movements of the rod and pin in the same manner as heretofore
described. "If it be desired to reproduce an image or object in any other position
than a horizontal plane the axis of the base can be changed to correspond, even
to a horizontal, in which position the reproductions or reversions can be made
in a vertical plane.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
