PROVISIONAL SPECIFICATION.
Improvements in Instruments for Delineating the Uterine and other
Cavities of the Human Body.
I FRANK WOOD HAVILAND, of 214 West 123rd Street, New York City,
United States of America, Physician do hereby declare the nature of this invention
to be as follows:-
My invention relates to instruments for the treatment of the uterus, and especially
to that class of instruments adapted to disclose the shape and dimensions of the
uterine cavity, or other cavities. The instrument is arbitrarily designated an
endograph, as the object sought to be attained is to provide an instrument which
will, when introduced into the uterus, follow the wall of the uterine cavity, and
likewise the wall of the cervical canal and automatically produce a diagram
accurately illustrating the angles of the body cavity of the uterus, the length of
the angles, the shape of said cavity, and likewise the length of the cervical canal
from the mouth or external oss to the internal oss.
A further feature of the invention is to construct an instrument of the
character above described which may be conveniently and expeditiously operated
by one individual, and which will be simple in construction and capable of being
readily dismantled and each part thoroughly cleaned.
The body or frame of the instrument comprises a table or base plate of any
approved shape, usually rectangular, a front and a rear cross head supported upon
the end portions of the base, and a casing of tube like construction which passes
through and is attached to each cross head and extends a predetermined distance
beyond the front head. The casing is parallel with the base and is usually straight.
Exteriorly the casing may be circular, oval, square, or polygonal in cross section,
but its interior is square in cross section or practically so.
The casing is provided at its rear with opposing side openings longitudinally
formed thereon and extending from a point at the rear of the forward cross head
through the rear end. Thus, the rear of the casing comprises two members, one
over the other, and the upper member is secured to the rear cross head, but the
lower member is free at its rear end, being normally supported in proper position
with respect to the upper member by a latch or keeper pivoted to one upright
section of the rear cross head and having locking engagement with the opposing
and corresponding head section. The forward head or end of the casing is usually
gradually reduced and rendered more or less pointed, and adjacent to the head,
opposing longitudinal openings are made in its sides.
A sleeve is loosely mounted upon the forward portion of the casing capable of
being moved rearward as far as the forward cross head. The sleeve may be
prevented from turning by forming a feather upon the casing, but the sleeve is held
in whatever position it may be placed by a set screw or its equivalent, and the set
screw when used is provided with a stud upon its head to form a lock for forceps
employed in connection with the instrument. The sleeve is adapted to serve as a
gage and its forward end is enlarged and provided with a guide pin, and if the
sleeve is very long, openings are made in its sides at its forward end to register
with the forward casing openings. In order to facilitate a quick and accurate
adjustment of the sleeve, a scale in inches and fractions thereof may be, and
preferably is, provided upon the casing adjacent to the front cross head.
The tracing mechanism and the delineating mechanism are carried by a single
bar which I will denominate a carriage, and both the tracing and the delineating
mechanisms are operated simultaneously and in perfect unison by connected sliding

page_text: bars which will be hereinafter spoken of as an expanding slide since its main
function is to force the tracing fingers in contact with opposite walls of the uterine
cavity of the uterus and place the delineating mechanism in position to follow the
movement of the tracing fingers; but the slide has also a second function, that of
compelling the delineating mechanism to move at all times in exact direction with
the tracing fingers and produce a diagram of the cavity the tracing fingers have
explored.
The body of the carriage consists of a bar provided at its rear end with a handle
preferably roughened to facilitate grasping, and a finger guard or loop at the
handle end. The tracing fingers are located at the forward end of the carriage,
and are pivoted upon opposite faces of the carriage near opposite side edges. The
inner ends of the fingers are wider than any other portion and a pin is located upon
the inner end of each finger, the pins being nearly opposite the pivots, yet removed
some distance from them. The outer ends of the fingers are made quite smooth to
prevent them from unduly irritating the parts with which they are to engage.
The fingers are furthermore preferably slightly curved, and their outer ends are
usually thickened upon opposite sides in order that the fingers may fold one upon
the other and interlock.
The carriage between its centre and handled end is reduced in thickness upon
both faces and at this point the delineating mechanism is located. This mechanism
consists of two plates or bars pivoted upon the opposite sides of the carriage in
like manner as the tracing fingers, and each plate or bar is provided with an
extension, projecting in direction of that side edge of the carriage opposite which
the particular plate or bar is pivoted and each extension carries a pin. Each plate
or bar carries a socket for the reception of a pencil or other form of marker said
sockets being located below the pivoted plates. The sockets may be constructed
in various ways and the connection between the sockets and plates may be differently
made. The following construction is however preferably employed and consists as
follows:-
☑
A vertically located tube constituting the socket is connected with one end of a
horizontal tubular arm and said arm is connected with the plate or bar to which it
belongs by an upright post, secured to the underface of the plate or bar between its
pivot point and outer end, ordinarily near the rear edge; and the attachment is so
made that the arm is diagonally located with respect to the plate, the outer portion
diverging from the pivot of the plate. Thus when the plates are in their unfolded
or outer position, the arms will be at angles to each other.
The marking material placed in the socket is maintained therein by frictional
engagement with a spring-pressed plunger located in the arm, the spring being
brought under variable tension by a set screw. The marking material or pencil is
normally held point below the socket by a spring passed through the rear of the
arm engaged by the set screw, one end of the spring having bearing against the
underface of the arm while the other end is bowed over the top of the arm and
enters a recess in the top of the socket in order that it may press against the upper
end of the marking material. When the tracing fingers are closed together, the
arms of the delineating mechanism occupy a corresponding position beneath the
carriage.
The bars of the expanding slide lie one above and the other below the carriage
and said bars are provided at each side of their centres with slots having slideways
at their sides extending nearly to one end and each of these slots receives a stud
secured upon the carriage. The studs are headed and their heads have bearing
upon the slides in the slots. By this means the bars of the expanding slide have
movable connection with the carriage. The upper slide bar is provided in one side
edge, the right-hand edge for example, with two recesses adapted to snugly receive
the pins carried by the right-hand tracing finger and plate of the right-hand
section of the delineating mechanism. The lower slide bar is provided with similar
recesses in its left-hand side receiving the pins of the left-hand tracing finger and
corresponding section of the delineating mechanism.

page_text: The slide bars are each provided with a handle at the rear end, extending at an
angle beyond the left-hand side of the carriage, and the two handles are connected
in any suitable manner. From the foregoing construction it will be observed that
if the handle of the expanding slide is pushed forward both the tracing fingers and
delineating arms will be forced outward or will be expanded simultaneously and
that as corresponding tracing fingers and delineating arms have corresponding pivots
and are correspondingly connected with the expan ling slide to whatever extent or
in whatever direction the fingers move, the corresponding delineating arms may be
moved also.
After the carriage and expanding slide have been connected, they are placed in
the frame in the following manner :-The latch at the rear of the frame is opened
and the arm, the finger end of the carriage and the slide are introduced into the
slotted end of the casing, the finger being closed, and when the fingers have reached
the head of the casing the delineating arms will have passed beneath the rear
crosshead of the frame and will have taken a position near the forward crosshead
over the base. The latch is then closed, holding the carriage snugly yet capable of
sliding in the casing. The casing is provided with a set-screw, by means of which
the carriage and expanding slide can be locked in the casing. In order to relieve
the pivots of the delineating arms from pressure while the marker is in operation,
I provide a release bar. The bar may be made of any desired material, is of
greater width and thickness, and has an arch formed at its central portion. The
bar is passed beneath the yoke section of the outer spring of both arms, extending
from one to the other, the arch being in engagement with the under face of the
casing. Thus no matter how much upward tension may be exerted upon the arms
by the markers it will not be communicated to the pivots of the arms but will be
sustained by the release bar and casing. The release bar has another function ;
by turning it upon its edge the outer marker springs will be lifted from the markers
and from contact with the base or whatever is placed upon the base to be drawn
upon.
The forceps used in connection with the instrument are of the self-locking pattern,
their jaws are hook-shaped, and when the forceps are locked extend one over the
other. Back of their pivot the members of the forceps have aligning recesses
produced in them to receive the stud upon the set screw of the guide sleeve.
The uterus comprises a body section and a neck section. Within the body section
the uterine cavity is located which, when the uterus is cut longitudinally through
its widest portion and is viewed from the front, discloses the slanting side walls of
the cavity, the lines diverging from the internal oss. The cervical canal is located
in the neck and extends from the external oss to the internal oss.
In certain diseases of the uterus it is of great advantage to know the shape and
dimensions of the uterine cavity, especially the angle of its walls and the length of
the cervical canal. The instrument described is adapted for this purpose and is
operated in the following manner :-The uterus is first measured with a graduated
sound to ascertain its length. If the length is found to be three inches, for example,
the sleeve is adjusted and secured upon the body casing to provide the space of
three inches between the head of the casing and the forward end of the sleeve.
The tracing fingers are closed and brought close to the head of the casing, which
brings the delineating arms near the front cross-head of the frame. Next a piece
of paper is placed upon the base of the frame over which the markers are to travel.
The uterus is now grasped at the anterior lip of the canal by the jaws of the
forceps and the head of the casing is introduced into the cervical canal at the
external oss. By gradually working the head of the instrument into the uterine
cavity and drawing the neck down over the casing the exterior oss will be brought
to the outer end of the guide sleeve and at that time the head of the instrument
will be practically in engagement with the upper wall of the body or uterine
cavity. The forceps are now locked upon the instrument. Next the operator
presses forward upon the handle of the expanding slide which action throws out
the tracing fingers to an engagement with opposite sides of the body cavity and

page_text: the delineating arms move in the same direction. Gentle pressure is continued to
be exerted upon the expanding slide to keep the tracing finger always in engage
ment with the walls of the uterine cavity and cervical canal and the carriage
and slide are both gently and slowly withdrawn from the uterus, and as the fingers
follow the outline of the uterine cavity and canal the markers carried by the
delineating arms faithfully delineate the shape of the interior of the uterus upon the
paper. The forceps being locked upon the instrument, the operator has both hands
to work with and therefore may proceed with steadiness and rapidity.
In a modification of the device the delineating apparatus is simplified to a great
extent and instead of pencils being employed to produce delineations a carbon or
transfer paper is used in connection with solid or hard points and the paper or
other substance upon which the delineatio is to be made. A table is provided
of somewhat box form, being provided with flanges at its sides, in order that
the table may receive a strip of carbon paper or the equivalent thereof.
The table is provided at one end with spurs and at the other end with a handle
and clamps of any approved description at each side of the handle. The paper
upon which the drawing is to be made is placed upon the carbon sheet and is
carried over upon the end of the table upon which the spurs are located, the
spurs by passing through the paper serving to hold said paper in place. The
paper may likewise be carried beneath the under surface of the table. The carbon
paper is passed beneath the clamps at the side of the handle and is maintained
in position primarily through their agency. The table with the paper thereon
is to be slid upon the base beneath the delineating arms. To that end an
opening is made in the front crosshead to permit the passage of the table and
the said opening is closed, when the table is in place, through the medium of a latch
which will prevent the table from moving outward, while the table is prevented from
having lateral movement by reason of the spurs being arranged in pairs and made to
pass at opposite sides of the pillars of the front crosshead. The base is provided with
a longitudinal slot in its central portion and also preferably with a finger piece
extending downward from the forward wall of said slot. The delineating device
is exceedingly simplified. The plates are each provided with a stud extending
downwardly therefrom, as in the construction heretofore described, but each stud is
attached to one end of a solid arm and each of the arms is provided at its free end
with a socket adapted to receive a marking point which point may be of metal and
in the nature of a screw in order that it may be adjusted to or from the surface over
which it is to travel. The operation of the instrument is identical with that hereto-
fore described, with the exception that when the base is held the operator will press
up against the bottom of the table which may be accomplished through the medium
of a slot in the base, and in this manner the carbon or transfer sheet and the paper
to be drawn upon will be held in proper engagement with the markers, and as the
body of the instrument is manipulated and the fingers follow the outline of the
cavity to be delineated, the delineating arms moving correspondingly will cause
the delineation of the shape of the cavity to appear upon the paper.

Improvements in Instruments for Delineating the Uterine and other
Cavities of the Human Body.
I, FRANK WOOD HAVILAND, of 214, West 123rd Street, New York City, in
the County and State of New York, United States of America, Physician, 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:-
My invention relates to instruments for the treatment of the uterus, and especially
to that class of instruments adapted to disclose the shape and dimensions of the
uterine cavity or other cavities. The instrument is arbitrarily designated an
endograph, as the object sought to be attained is to provide an instrument which
will, when introduced into the uterus, follow the wall of the uterine cavity, and
likewise the wall of the cervical canal, and automatically produce a diagram
accurately illustrating the angles of the body cavity of the uterus, the length of
the angles; the shape of said cavity, and likewise the length of the cervical canal
from the mouth or external oss to the internal oss. A further feature of the
invention is to construct an instrument of the character above described which may
be conveniently and expeditiously operated by one individual, and which will be
simple in construction and capable of being readily dismantled and each part
thoroughly cleaned.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar figures and letters of reference indicate corresponding
parts in all the views.

the body of the instrument, the said mechanism being in normal and folded position,
and a portion of the upper slide bar removed;
Figure 7 is a view similar to that shown in Figure 6, but the tracing and
delineating mechanism is shown in full expanded position and both slide bars are
shown in place;

a portion of the former being in vertical section;
Figure 9 is a section taken practically on the line 9-9 of Figure 7, showing the
delineating mechanism in front elevation;
Figure 10 is a perspective view of the shifting device employed in connection
with the delineating mechanism;
Figure 11 is a side elevation of a modified form of the endograph;
Figure 12 is a vertical section taken through the body portion of the endograph;
Figure 13 is a horizontal section through the uprights upon the body of the
modified form of endograph, illustrating the said body in plan view, and likewise
illustrating the carbon or transfer paper or material, and the paper upon which the
delineation is to be made in position on the body; and
Figure 14 is a vertical section taken practically on the line 14-14 of Figure 12.
The body or frame of the instrument comprises a table or base plate 10, of any

page_text: approved shape, usually rectangular, a front and a rear cross head supported upon
the end portions of the base and designated as 11 and 12, and a casing 13, of
tube-like construction, which passes through and is attached to each cross head,
and extends a predetermined distance beyond the front head. The casing 13, is
parallel with the base and is usually straight, as illustrated. Exteriorly the casing
may be circular, oval, square or polygonal in cross section, but its interior is square
in cross section, or practically so.
The casing is provided at its rear with opposing side openings 14, longitudinally
formed thereon and extending from a point at the rear of the forward cross head
through the rear end. Thus the rear of the casing comprises two members, one
over the other, and the upper member is secured to the rear cross head, but the
lower member is free at its rear end, being normally supported in proper position
with respect to the upper member by a latch or keeper 15, pivoted to one upright
section of the rear cross head and having locking engagement with the opposing
and corresponding head section, as shown in Figures 2 and 3. The forward head
or end of the casing is usually gradually reduced and rendered more or less pointed,
and adjacent to the head opposing longitudinal openings 16, are made in its sides.
A sleeve 17, is loosely mounted upon the forward portion of the casing, capable
of being moved rearward as far as the forward cross head. The sleeve may be
prevented from turning by forming a feather upon the casing, but the sleeve is held
in whatever position it may be placed by a set screw 18, or its equivalent, and the
set screw, when used, is provided with a stud 19 upon its head to form a lock for
forceps A, employed in connection with the instrument. The sleeve is adapted to
serve as a gage, and its forward end is enlarged and provided with a guide
pin 20; and if the sleeve is very long openings are made in its sides at its
forward end to register with the forward casing openings 16. In order to facilitate
a quick and accurate adjustment of the sleeve a scale in inches and fractions
thereof may be, and preferably is, provided upon the casing adjacent to the front
-cross head.
The tracing mechanism B and the delineating mechanism D, are carried by a
single bar 21, which I will denominate a carriage, and both the tracing and
the delineating mechanisms are operated simultaneously and in perfect unison by
connected sliding bars 22 and 23, which will be hereinafter spoken of as an
expanding slide, since its main function is to force the tracing fingers 24 and 25 in
contact with opposite walls of the uterine cavity of the uterus and place the
delineating mechanism in position to follow the movement of the tracing fingers;
but the slide has also a second function, that of compelling the delineating mechanism
to move at all times in exact direction with the tracing fingers and produce a diagram
of the cavity the tracing fingers have explored.
The body of the carriage consists of a bar provided at its rear end with a
handle 27, preferably roughened to facilitate grasping, and a finger guard or
loop 27 at the handle end. The tracing fingers 24 and 25, are located at the
forward end of the carriage, and are pivoted upon opposite faces of the carriage
near opposite side edges, the pivot points being best shown in Figure 7, and are
designated as a and a." The inner ends of the fingers are wider than any
other portion, and a pin 28, is located upon the inner end of each finger, the
pins being nearly opposite the pivots, yet removed some distance from them.
The outer ends of the fingers are made quite smooth to prevent them from unduly
irritating the parts with which they are to engage. The fingers are furthermore
preferably slightly curved, and their outer ends are usually thickened upon opposite
sides in order that the fingers may fold one upon the other and interlock, as shown
in Figures 6 and 8.
The carriage between its center and handled end is reduced in thickness
upon both faces, and at this point the delineating mechanism is located. This
mechanism consists of two plates or bars 29 and 30, pivoted upon the opposite
sides of the carriage in like manner as the tracing fingers, as shown best in
Figure 6, and each plate or bar is provided with an extension 31, projecting

page_text: in direction of that side edge of the carriage opposite which the particular
plate or bar is pivoted, as is best shown in Figure 7, and each extension carries
a pin 31º.
Each plate or bar 30 carries a socket 32, for the reception of a pencil or other
form of marker, said sockets being located below the pivoted plates. The sockets
may be constructed in various ways, and the connection between the sockets and
plates may be differently made. The construction shown in the drawing is however
preferably employed, and consists as follows:
A vertically located tube constituting the socket 32, is connected with one end
of a horizontal tubular arm 33, and said arm is connected with the plate or bar 30
to which it belongs by an upright post 34, secured to the under face of the plate
or bar between its pivot point and outer end, ordinarily near the rear edge; and
the attachment is so made that the arm is diagonally located with respect to the
plate, the outer portion diverging from the pivot of the plate. Thus when the plates
are in their unfolded or outer position, as shown in Figure 7, the arms will be at
angles to each other.
The marking material placed in the socket is maintained therein by frictional
engagement with a spring-pressed plunger 35, located in the arm 33, the spring
being brought under variable tension by a set screw 36. The marking material or
pencil is normally held, point below the socket, by a spring 37, passed through the
rear of the arm engaged by the set screw 36, as shown in Figure 8, one end of
the spring having bearing against the under face of the arm, while the other end
is bowed over the top of the arm and enters a recess in the top of the socket in
order that it may press against the upper end of the marking material, see
Figures 8 and 9. When the tracing fingers are closed together the arms of the
delineating mechanism occupy a corresponding position beneath the carriage, as
shown in Figure 6.
The bars 22 and 23 of the expanding slide lie one above and the other below the
carriage, and said bars are provided at each side of their centers with slots 38,
having slide-ways at their sides extending nearly to one end; and each of these
slots receives a stud 39, secured upon the carriage. The studs are headed, and their
heads have bearing upon the slides in the slots. By this means the bars of the
expanding slide have movable connection with the carriage. The upper slide bar 22,
is provided in one side edge, the right-hand edge for example, with two recesses 40
and 41, shown best in Figure 7, adapted to snugly receive the pins carried by the
right-hand tracing finger and plate of the right-hand section of the delineating
mechanism. The lower slide bar 23, is provided with similar recesses in its left-hand
side receiving the pins of the left-hand tracing finger and corresponding section of
the delineating mechanism.
The slide bars 22 and 23, are each provided with a handle 42 at its rear
end, extending at an angle beyond the left-hand side of the carriage, as shown
in Figure 1, and the two handles are connected in any suitable manner.
From
the foregoing construction it will be observed that if the handle of the expanding
slide is pushed forward, both the tracing fingers and delineating arms will
be forced outward, or will be expanded simultaneously, and that as corre-
sponding tracing fingers and delineating arms have corresponding pivots, and
are correspondingly connected with the expanding slide, to whatever extent or
in whatever direction the fingers move the corresponding delineating arms may
be moved also.
After the carriage and expanding slide have been connected, they are placed in
the frame in the following manner :
The latch at the rear of the frame is opened, and the arm, the finger end of
the carriage and the slide are introduced into the slotted end of the casing, the
finger being closed, and when the fingers have reached the head of the casing the
delineating arms will have passed beneath the rear cross head of the frame and
will have taken a position near the forward cross head over the base. The latch

page_text: is then closed, holding the carriage snugly yet capable of sliding in the casing.
The casing is provided with a set screw 43, by means of which the carriage and
expanding slide can be locked in the casing. In order to relieve the pivots of the
delineating arms from pressure while the marker is in operation, I provide a
release bar 44, shown in Figure 10. The bar may be made of any desired
material, is of greater width than thickness and has an arch 45, formed at its
central portion. The bar is passed beneath the yoke section of the outer spring 37
of both arms, extending from one to the other, the arch being in engagement with
the under face of the casing, as is best shown in Figure 1. Thus no matter how
much upward tension may be exerted upon the arms by the markers it will not
be communicated to the pivots of the arms, but will be sustained by the release
bar and casing.
The release bar has another function; by turning it upon its edge the outer
marker springs will be lifted from the markers and from contact with the base, or
whatever is placed upon the base to be drawn upon.
The forceps A, used in connection with the instrument are of the self-locking
pattern; their jaws 46, are hook-shaped, and when the forceps are locked extend
one over the other. Back of their pivot the members of the forceps have
aligning recesses 47, produced in them to receive the stud 19 upon the set
screw 18 of the guide sleeve 17.
The uterus comprises a body section E, see Figure 1, and a neck section E'.
Within the body section the uterine cavity E2, is located, which when the uterus
is cut longitudinally through its widest portion and is viewed from the front, as
in Figure 1, discloses the slanting side walls of the cavity, the lines diverging
from the internal oss, the point of which is indicated at e. The cervical canal e¹,
is located in the neck, and extends from the external oss e² to the internal oss e.
In certain diseases of the uterus it is of great advantage to know the shape
and dimensions of the uterine cavity, especially the angle of its walls and the
length of the cervical canal. The instrument described is adapted for this purpose,
and is operated in the following manner :
The uterus is first measured with a graduated sound to ascertain its length;
if the length is found to be three inches, for example, the sleeve 17 is adjusted
and secured upon the body casing to provide the space of three inches between
the head of the casing and the forward end of the sleeve. The tracing fingers
are closed and brought close to the head of the casing, as shown in Figure 2,
which brings the delineating arms near the front cross head of the frame. Next
a piece of paper C, is placed upon the base of the frame over which the markers
are to travel.
The uterus is now grasped at the anterior lip of the canal by the jaws of the
forceps, and the head of the casing is introduced into the cervical canal at the
external oss by gradually working the head of the instrument into the uterine
cavity and drawing the neck down over the casing, the exterior oss will be brought
to the outer cal of the guide sleeve, and at that time the head of the instrument
will be practically in engagement with the upper wall of the body or uterine cavity,
as shown in Figure 1. The forceps are now locked upon the instrument. Next
the operator presses forward upon the handle of the expanding slide, which
action throws out the tracing fingers to an engagement with opposite sides of the
body cavity, and the delineating arms move in the same direction. Gentle
pressure is continued to be exerted upon the expanding slide to keep the tracing
finger always in engagement with the walls of the uterine cavity and cervical
canal, and the carriage and slide are both gently and slowly withdrawn from the
uterus, as shown in dotted lines, Figure 1, and as the fingers follow the outline of
the uterine cavity and canal the markers carried by the delineating arms faithfully
delineate the shape of the interior of the uterus upon the paper. The forceps
being locked upon the instrument the operator has both hands to work with and
therefore may proceed with steadiness and rapidity.

page_text: In Figures 11, 12, 13 and 14, I have illustrated a modification of the device,
in which the delineating apparatus is simplified to a great extent, and instead of
pencils being employed to produce delineations a carbon or transfer paper is used
in connection with solid or hard points and the paper or other substance upon
which the delineation is to be made.
A table 50, is provided of somewhat box form, being provided with flanges at
its sides, in order that the table may receive a strip of carbon paper 51, or the
equivalent thereof. The table is provided at one end with spurs 52, as shown in
Figure 13, and at the other end with a handle 54, and clamps of any approved
description at each side of the handle. The paper 53 upon which the drawing is
to be made is placed upon the carbon sheet 51, and is carried over upon the end
of the table upon which the spurs 52 are located, the spurs by passing through
the paper serving to hold said paper in place. The paper may likewise be carried
beneath the under surface of the table. The carbon paper is passed beneath the
clamps at the side of the handle 54, and is maintained in position primarily through
their agency.
The table, with the paper thereon, is to be slid upon the base beneath the
delineating arms. To that end an opening is made in the front crosshead to permit
the passage of the table, and the said opening is closed when the table is in place
through the medium of a latch 55, which will prevent the table from moving
outward, while the table is prevented from having lateral movement by reason of
the spurs 52 being arranged in pairs and made to pass at opposite sides of the
pillars of the front cross head 11, as is also best shown in Figure 13. The base
is provided with a longitudinal slot 56 in its central portion, and also preferably
with a finger piece 57, extending downward from the forward wall of said slot, as
illustrated in Figure 12.
The delineating device is exceedingly simplified; the plates 29 and 30, are each
provided with a stud 34, extending downwardly therefrom, as in the construction
beretofore described, but each stud is attached to one end of a solid arm 58, and
each of the arms is provided at its free end with a socket adapted to receive a
marking point 59, which point may be of metal and in the nature of a screw in
order that it may be adjusted to or from the surface over which it is to travel.
The operation of the instrument is identical with that heretofore described, with
the exception that when the base is held the operator will press up against the
bottom of the table, which may be accomplished through the medium of the slot 56,
in the base, and in this manner the carbon or transfer sheet and the paper to be
drawn upon will be held in proper engagement with the markers; and as the body
of the instrument is manipulated, and the fingers 24 and 25 follow the outline of
the cavity to be delineated, the delineating arms moving correspondingly will
cause the delineation of the shape of the cavity to appear upon the paper 53.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is,-
1. An endograph for delineating the shape of cavities, constructed substantially
as shown and described.
2. An instrument of the character described, comprising a carrier, an expansible
tracer on the forward end of the carrier and contracted or folded by the walls of
the cavity being traced as the instrument is being moved therealong, and a
delineator mounted upon one end of the said carrier, connected with the tracer
and operated thereby, substantially as set forth.
3. An instrument for delineating the uterine and like cavities of the human
body, the same comprising tracing fingers, and a delineating device operated by the
said tracing fingers, substantially as set forth.
4. An instrument for delineating the uterine and like cavities of the human
body, the same comprising tracing fingers, a delineating device, and means,
B

page_text: substantially as described, for imparting concerted action and movement in the same
direction to both the fingers and delineating device, as and for the purpose specified.
5. An instrument for delineating the uterine or like cavities of the body, com-
prising tracing fingers, a delineating device, and a transmitting device connecting
them, whereby the movement of the fingers is precisely followed by the delineating
device, as and for the purpose specified.
6. An instrument for delineating the uterine cr like cavities of the body, con-
sisting of a carriage, tracing fingers, and a delineating device connected with the
carriage, and a transmitting and expanding device having movement independent
of the carriage, and connecting the fingers with the delineating device, substantially
as described.
7. In an instrument for delineating the uterine and other cavities of the human
body, a carriage, tracing fingers located thereon, capable of folding upon and
outward from the carriage, and delineating arms likewise pivoted upon the carriage,
having concerted movement with and similar movement to the tracing fingers,
substantially as shown and described.
8. In an instrument for delineating the uterine and other cavities of the human
body, the combination, with a casing tube and table, of a carriage having sliding
movement in a casing, tracing fingers pivotally connected with the forward portion
of the carriage, a delineating device similarly attached to the carriage over the
table, and an expanding device having movement upon the carriage and connected
with the tracing fingers and the delineating device, communicating the same nlove-
ment to both, substantially as set forth.
9. In an instrument for delineating the uterine and other cavities of the human
body, the combination, with a casing tube and table, the said tube being provided
with a lock at its rear end, and side openings near said rear end and near its
forward end, of a carriage and an expanding device having independent movement
upon the carriage, the carriage and expanding device being removably and loosely
located within the casing, tracing fingers pivotally connected with the carriage and
operated upon by the expanding device, the fingers being adapted to fold within
the casing and extend outward through its forward openings, delineating arms
likewise pivotally connected with the carriage and extending outward through the
rear openings therein, said delineating arms being operated by and connected with
the expanding device, and a gage mounted upon the casing and having adjustable
connection therewith, as and for the purpose set forth.
10. In an instrument for delineating the uterine and other cavities of the human
body, the combination, with a casing tube and table, of a carriage having sliding
movement in the casing, tracing fingers pivotally connected with the forward
portion of the carriage, adapted to fold within the casing and extend outward from
opposite sides thereof, and delineating arms likewise pivotally connected with the
carriage and extending one beyond each side thereof over the table, of an expanding
device having movement upon the carriage and within the casing, the said expand-
ing device being connected with the tracing fingers and delineating arms, commu-
nicating a like movement to each, a gage sleeve located upon the forward portion
of the casing, said sleeve being adjustable, and means, substantially as shown and
described, for connecting forceps with the casing section of the instrument, as and
for the purpose set forth.
11. In an instrument for delineating the uterine and other cavities of the human
body, a carriage, delineating arms pivotally connected with the carriage, spring-
pressed markers connected with the arms, and a releasing bar engaging the marker
springs, substantially as described.
12. In an instrument for delineating the uterine and other cavities of the human
body, a support, a carriage having sliding movement in the support, delineating
arms pivotally connected with the carriage, spring-controlled markers connected
with the arms, and a releasing bar engaging with the marker springs and the
Carriage support, whereby said bar serves for releasing the markers from pressure,
