" IMPROVE
This Invention relates to certain improvements in or applicable to endorsing
stamps, the object being to provide a combined stamp or die and inking pad, par-
ticularly applicable to the use or employment of india-rubber endorsing or printing
stamps, and differing essentially from stamps or dies of this kind now in use in
that there are two distinct actions of the apparatus, (1) for inking the stamp, and
(2) for giving off the impression, whilst always following the action of giving the
impression the inking pad is automatically brought into position for again inking
the stamp.
The Invention consists of an apparatus or machine for the better and more con-
venient use of stamps or dies for stamping, endorsing, and printing, and is arranged
in such manner that the inking pad is attached to the machine, so that it may be
brought into position for inking the die, after which the frame to which the inking
pad is attached automatically assumes a position which allows the inked die to be
in readiness for printing; a portion of the inking pad frame will then serve as a
guide, and is arranged and constructed so that the die is actuated or carried down
parallel to the surface to be printed upon, thereby securing a perfect impression,.
and also the stamp when not in use is not left in contact with the inking pad.
This arrangement admits of inking and stamping with more convenience and
accuracy, as well as the device being in a more compact form than when the pad

page_text: is separate from the stamp, and the simplicity of its construction and consequent
cheapness also recommends it.
I will now describe more fully the construction of the device.
A frame or yoke is constructed of two projecting ears or arms at right angles to
a horizontal cross bar, which is the third side of the said yoke. Between the pro-
jecting side arms and through the cross bar an opening is arranged, and in this is
provided a neck or collar piece to act as a guide to a tubular plunger free to play
up and down through the opening between the projecting side arms and parallel
thereto.
To one end of the plunger is attached a flat piece of metal or other rigid material,
which will serve as the backing to which the stamp or die is secured, and to the
opposite end of the plunger a handle or knob is attached.
Within the tubular plunger and between the handle and the cross bar of the
yoke or frame, through which is the guide opening in which the said plunger
works, a spiral spring is arranged, and acts upon a cross pin or stud free to work
in a vertical slot in the plunger tube, said cross pin or stud acting or bearing against
the cross bar of the yoke in such manner that when the plunger is pressed down the
spring is compressed, and upon its being released the plunger is carried by the re-
coil of the spring back to its original position.
The yoke frame to which the plunger is secured has attached thereto by studs
(preferably at the extremities of the yoke arms) another frame, which is the inking
pad frame, having also three sides, two of which are at right angles to the other.
To the bottom (to which the two sides are at right angles), is attached on the inner
side the inking pad, and the two sides are strengthened and held rigidly together at
their opposite extremities by a tie bar. This inking pad frame is pivoted through
the side arms to the arms of the yoke frame carrying the plunger and stamping
die in such manner that the plunger when forced down will press the die upon the
inking pad, and upon its being raised a partial revolution of the frame brings the
inking pad at right angles to the inked stamping die, leaving it, the stamping die,
in a position to be pressed down to make an impression, the projecting arms of the
inking pad frame serving as a support or stand and guide, so that the stamping die
in being pressed is parallel to the surface to be printed upon.
The normal position of the device is that the stamping die is always ready to give
an impression by depressing the plunger.
In order to effect the necessary change of relative position of the inking pad
frame with regard to the stamping die a spring or springs is or are provided to
work in connection with the inking pad stand so as to give to the inking pad,
after the stamp or die has received the ink, a partial revolution, and bring the pad
up out of the way in position at right angles to the stamping die, when a clear
space will be left below the stamping die for giving off the impression.
The spring or springs for working the inking pad frame may be a volute working
in a boxing at the extremities of the ears of the yoke frame, or be a spiral spring
or springs, or india-rubber band springs attached from the yoke frame to the arms
of the inking pad frame.
The extremity of the inking pad frame and opposite to the inking pad may be
weighted to counterpoise the said inking pad, which will operate to throw the said
inking pad out of position, as before described.
In order to ensure that the stamping die may always assume a level position
with regard to the surface to be printed, stamped, or endorsed upon, and thereby
impart a more perfect impression, the plate carrying the die may be loosely jointed
to the plunger by ball-and-socket or other similar arrangement, so that the stamping
die may slightly oscillate, and when pressed down assume a parallel position with
regard to the surface to receive the impression, and thereby assist in the perfection
of the printing.
In use the handle is grasped by the hand of the operator, and the yoke is made
to take a partial revolution so as to bring the stamping die over and parallel to the
inking pad, whereupon the plunger is pressed down so as to ink the stamping die,

page_text: and upon raising the apparatus, the pad frame by means of the side springs or
counterweight, or both, will make a partial revolution and leave the stamping die
clear and ready to be forced down upon the surface to be stamped, printed, or
endorsed.
If the pin or stud, which works in the vertical slot of the plunger tube and
secures the lower end of the spring to force up the plunger after stamping, as
herein-before described, be removed and re-adjusted so as to hold the spring within
the plunger tube below the cross bar of the yoke frame, the function of the appa-
ratus will be materially altered, and the stamp will assume a compact form suitable
for carrying in the pocket, as the stamping die will then be held down upon the
inking pad, thereby protecting both, and inking the die at the same time, and by
pressing the yoke frame so as to bring the die away from the inking pad the inking
pad frame will make an automatic partial revolution by action of its spring or
springs and leave the die exposed ready for giving off an impression.
A small arrangement of this device, as last described, but with the plunger tube
constructed at its outer extremity as a socket, will form a very efficient adjunct to
an ordinary lead pencil or penholder, serving as a point protector and a portable
die or stamp.

IMPROVE-
This Invention relates to certain improvements in or applicable to endorsing
stamps, the object' being to provide a combined stamp or die and inking pad
particularly applicable to the use or employment of india-rubber endorsing or
printing stamps, and differing essentially from stamps or dies of this kind now in
use.
The Invention consists of an apparatus or machine for the better and more
convenient use of stamps or dies for stamping, endorsing and printing, and is
arranged in such manner that the inking pad is attached to the machine so that it
may be brought into position for inking the die, after which the frame to which
the inking pad is attached automatically assumes a position which allows the inked
die to be in readiness for printing; a portion of the inking pad frame will then
serve as a guide, and is arranged and constructed so that the die is actuated or
carried down parallel to the surface to be printed upon, thereby securing a perfect
impression, and also the stamp, when not in use, is not left in contact with the
inking pad.
This arrangement admits of inking and stamping with more convenience and
accuracy, as well as the device being in a more compact form than when the pad is
separate from the stamp, and the simplicity of its construction and consequent
cheapness also recommends it.
I will now describe more fully the construction and working of the device.

Fig. 13 shows a modification of this apparatus arranged as a pencil holder or
point protector and stamp.
Fig. 14 represents in perspective view, partly in section, further modification, and
Fig. 15, under view of the stamp or die plate, partly in section.

page_text: A frame or yoke piece A is constructed of two projecting ears or arms at right
angles to a horizontal cross bar, which is the third side of the said yoke. Between
the projecting side arms, and through the cross bar, an opening is arranged, and in
this is provided a neck or collar piece B to act as a guide to a tubular plunger C
free to play up and down through the opening between the projecting side. arms,
and parallel thereto.
To one end of the plunger is attached a flat piece of metal or other rigid material
which will serve as the backing to which the stamp or die D is secured, and to the
opposite end of the plunger C a handle or knob is attached.
Within the tubular plunger C, and between the handle and the cross bar of the
yoke or frame A, through which is the guide opening Bin which the said plunger C
works, a spiral spring is arranged and acts upon a cross pin or stud E, free
work
in a vertical slot C' in the plunger tube, said cross pin or stud E being secured to
the guide collar B, and acting or bearing against the cross bar of the yoke A in such
manner that when the plunger C is pressed down the spring is compressed, and
upon its being released the plunger is carried by the recoil of the spring back to its
original position.
The yoke frame A to which the plunger C is secured has attached thereto by.
studs F (preferably at the extremities of the yoke arins) another frame G, which is
the inking pad frame, having also three sides, two of which are at right angles to
the other. To the bottom (to which the two sides are at right angles) is attached
on the inner side the inking pad H, and the two sides are strengthened and held
rigidly together at their opposite extremities by a tie-bar G: This inking pad
frame is pivoted by the pivots F through the side arms to the arms of the yoke
frame A, carrying the plunger C and stamping die D in such manner (see Figs 1
2) that the plunger C when forced down will press the die D upon the inking
pad H, and upon its being raised a partial revolution of the frame brings the inking.
pad at right angles to the inked stamping die (see Fig. 1), leaving it, the stamping
die, in a position to be pressed down to make or give off an impression, the pro-
jecting arms of the inking pad frame G serving as a support or stand and guide, so
that the stamping die in being pressed down is parallel to the surface to be printed
upon, as shown in the said Fig. 1.
The dotted lines in Fig. I indicate the change of position of the inking pad
frame G whilst inking the stamp, and the throw of the said frame G is regulated
by two shoulders G² at each extremity of a curved portion of the frame G, which
will "stop" against the yoke bar A.
In order to effect the necessary change of relative position of the inking pad
frame G with regard to the stamping die D a spring or springs I is or are provided
to work in connection with the inking pad frame G so as to give to the said inking
pad, after the stamp or die has received the ink, a partial revolution, and bring the pad
up out of the way in position at right angles to the stamping die, as clearly shown
in Fig. 1, when a clear space will be left below the stamping die for giving off the
impression. The line x, x, represents the line of the surface on to which the
impression of the stamping die is to be given off.
The spring or springs I for working the inking pad frame G may be a volute
working in a boxing, as shown at I', Fig. 3, at the extremity or extremities of the
ears of the yoke frame A, or be a spiral spring or springs, as in the arrangement
shown in Figs. 8 to 12, or india-rubber band springs attached from the yoke frame
A to the arms of the inking pad frame G, as shown in Figs. 1, 3, 4, 5.
The extremity of the inking pad frame at G¹ and opposite to the inking pad H,
may be weighted to counterpoise the said inking pad, which will operate to throw
the said inking pad out of position, as before described.
In order to ensure that the stamping die may always assume a level position
with regard to the surface to be printed, stamped, or endorsed upon, and thereby
impart a more perfect impression; the plate carrying the die may be loosely
jointed to the plunger by ball-and-socket or other similar arrangement, so that

page_text: .
the stamping die may slightly oscillate, and when pressed down assume a parallel
position with regard to the surface to receive the impression, and thereby assist in
the perfection of the printing; but this arrangement is not shown on the Drawings,
as its application can be readily effected by any workman capable of making this
device.
In use the handle is grasped by the hand of the operator, and the inking pad
frame G is made to take a partial revolution, so as to bring the stamping die D
over and parallel to the inking pad H, whereupon the plunger is pressed down
so as to ink the stamping die; and upon raising the apparatus the pad frame
by means of the side springs I or counterweight G¹, will make a partial revo-
lution and leave the stamping die clear and ready to be forced down upon the
surface to be stamped, printed, or endorsed.
If the pin or stud E which works in the vertical slot C³ of the plunger tube C,
and secures the lower end of the spring to force up the plunger after stamping, as
herein-before described, be removed and re-adjusted so as to hold the spring within 1
the plunger tube below the cross bar of the yoke frame, as shown in Figs. 4 to 7, the
function of the apparatus will be materially altered, and the stamp will assume a
compact form suitable for carrying in the pocket, as the stamping die will then be
held down upon the inking pad, thereby protecting both and inking the die at the
same time, and by pressing the yoke frame so as to bring the die away from the 2
inking pad, the inking pad frame will make an automatic partial revolution by
action of its spring or springs, and leave the die exposed ready for giving off an
impression, as shown in Fig. 5.
After use the stamping die will be returned to the position, shown in Figs. 4
and 6, and this return action is indicated by the dotted lines of Fig. 5.
A small arrangement of this device as last described, but with the plunger tube
constructed at its outer extremity, as a socket is shown in Figs. 6 and 7, and will
form a very efficient adjunct to an ordinary lead pencil or penholder to serve as a
point protector therefor, and also as a portable die or stamp.
2
In Figs. 8 to 12, the yoke A as shown in the other Drawings is modified to a 3
yoke bar A¹, and works within the pad frame G, and is pivoted thereto by the
studs F. The yoke bar A¹ also carries a crank and stud A³, which takes into the
curved slot G³ (Fig. 9), whereby the throw of the frame G will be regulated.
The application of the springs I will be evident and readily understood upon
referring to the Drawings, and requires no further description.

A modification of this apparatus is shown in Fig. 13, arranged as a pencil holder
or point protector, and in this case the outer arms of the inking pad frame G, G¹, as
before described is done away with, and the spring I when the frame G is pressed
down by the operator (as indicated by the dotted lines of this Fig. 13), will impart
to the said inking pad frame G a partial revolution to throw same clear of the 4
stamp D, as from the previous description will be well understood.
Instead of rotating the inking pad frame as last described, and as shown in the
arrangement of apparatus, Figs. 6 and 7, I may rotate the die itself by means of the
spring I, as is shown in Figs. 14 and 15, wherein D is the stamp or die carrier
attached to the yoke piece A by the bar A¹, carrying the spring I which acts to
rotate the said die D; A is the yoke piece; B, the socket; C, the plunger
carrying its spring, which acts between the inking pad frame G and yoke piece
socket B.
As shown in Fig. 14, the die is in position for giving off an impression, but when
the stamp is required for use, the yoke piece A is to be pressed upward against the 5
spring of plunger C, so as to afford "clearance" for allowing the carrier D to be
partially rotated upon its yoke bar A¹ against the spring I, until it assumes the
position shown in Fig. 15, when the pressure is to be removed from the yoke
piece A, and pad G will by the plunger spring be held closely to the face of the die
to ink same, and hold the die frame D from being rotated by its spring I until 5
again required for use, when by pressing against yoke piece A die D will be carried.

page_text: free of the pad G, and spring I will act to partially rotate die into position for
giving off another impression. The side of the die carrier D is extended at D' to
form stops to regulate the throw or partial revolution of said die carrier.
In some cases it may be desirable to afford a cover for the inking pad, in which
case the metal of the stamp carrier D will be extended as at D', and the metal of
the inking pad frame will also be extended as at G³, which when the apparatus is
in position, as shown in Figs. 1 and 9, will afford a cover to the inking pad H.
Having now described the nature and particulars of the said Invention in such
wise that the same may be readily carried into practical effect I claim,-
First. In combination with the inking pad frame G and pad H, the movable
yoke A carrying the spring plunger C and die D, arranged and operating as herein
set forth and shown by the Drawings.
Second. In combination with the inking pad frame G and yoke A, the spring
I or I for automatically carrying the said inking pad frame G or die D into
position for allowing the impression to be given off from the stamping die D,
arranged and operating as set forth and as shown by the Drawings.
Third. The arrangement of the spring of the plunger C below the pin E in
combination with the yoke A, the die D, the inking pad frame G, and spring I,
arranged and operating as set forth and shown in Figs. 4 to 7.
Fourth. In combination with the yoke A or yoke bar A', and inking pad frame
G, the spring plunger C formed as a socket, as shown in Figs. 6, 7, 13, 14, and 15.
Fifth. The cross bar A¹ with pivots F, crank and stud A² in combination with
the inking pad frame G, and pivotted thereto in such manner that the stud A² will
work within the slot G2 of the inking pad frame G, and regulate the throw of the
said frame G effected by the spring I attached to the bar A¹ and frame G, the
whole constructed and operating as and for the purpose specified and shown in
Figs. 8 to 13.
In witness whereof, I, the said George Kissam Cooke, have hereunto set my
hand and seal, this Thirteenth day of February, One thousand eight
hundred and somente nine
