A Measuring Gauge for Hernia Trusses.
THOMAS JOSEPH KELLY, Templeshannon, Enniscorthy, County Wexford, Ireland,
Physician and Surgeon, do hereby declare the nature of this invention to be as
follows:-
Two flat steel bands joined together by a screw and clamp, having scales marked
on their outer surface where they over and under lap, The screw and clamp work
through a slot in the uppermost band and the end of the screw is fixed to the under-
most band. The two free ends are slotted and marked with scales and to each end
is clamped a pear shaped pad of rubber hollow and inflatable by means of a pump
which is graduated. On the surface of the pads there are quadrants marked with
reference numbers and letters. There is a reference card for recording the numbers
& letters in appropriate columns. On the inner surface of the steel bands where
they play over one another there is also an inflatable rubber pad of regulated
capacity. The pads are furnished with valves which confine the injected air in the
pads and when necessary by means of a screw adjustment permit the free exit of
the air.

A Measuring Gauge for Hernia Trusses,
I, THOMAS JOSEPII KELLY, Templeshannon, Enniscorthy, County Wexford, Ireland,
Physician and Surgeon, 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 hernia trusses and it has for object to construct a measur-
ing gauge which is easy of application to the person it is intended to measure
and it is so marked and constructed that its size, shape and the dimensions of the
various parts forming the gauge may easily be marked on a card or chart which
is sent to the truss maker. The latter is also provided with a similar gauge which
he adjusts to correspond with the chart so that instead of it being necessary for
the patient to be measured by the truss maker thus often involving loss of time and
expense the measurements may be taken by any properly qualified person filled
in on a measurement form and be transmitted to the truss maker who in turn is
in a position to make a truss which shall conform better to the patient than has

been possible hitherto except when the truss maker has himself taken the measure-
Even if the truss maker does directly take the measurements and particu-
lars he is in a better position to make a truss to fit well if he has a full sized model
or gauge before him, as is rendered possible by my invention, than he would be
if he had to depend on notes taken at the time of measuring or on his memory or 5
on both.
Figure 1 of the accompanying sheet of drawings represents the front view of a
gauge constructed according to my invention.
Figure 2 is a back view thereof and
Figure 3 represents one way of marking a card or form to facilitate the use of
such a gauge.
The truss gauge or model consists of two flat bands A and B of metal or other
suitable material joined together by a screw C and thumb nut D. Each of the
bands is provided as shown with scales marked A' and 13 respectively. The screw C
is suitably fixed to the band B and passes through a slot A2 in the band A. The
band A is provided with lugs or cars A3 A4 which embrace the band B and the
band B is provided with lugs or ears B3 B4 which similarly embrace the band A,
or the two bands A and B may be held clamped together in any other convenient
way. The two free ends or terminals of the bands A and B are slotted at A5 and B³
respectively and are marked with scales as shown and to each end is clamped by
screws and fly nuts E' F1 and E2 F2 a pear shaped pad of rubber one of which is
marked E and the other F. These pads are inflatable being provided with valves G
such as are used with pneumatic tyres for instance for confining injected air or
other fluid in the pads and for permitting of the exit of the fluid when required.
The india rubber pads are suitably provided with a covering of chamois leather
or the like if desired and have quadrants E3 and F³ marked with reference numbers
and letters.
On the inner surface of the steel bands and more particularly where they play
over one another there is also an inflatable rubber pad or lining H which is pro-
vided with a valve I of the same kind as the valve described with reference to the
letter G. The pad H may also if it be desired be covered with chamois leather or the
like. The pump or inflator K used for inflating the pads E F and H is constructed
in any convenient and well known manner and the hollow plunger K¹ or an
equivalent is suitably graduated as shown on the drawing so as to permit of the
operator filling the pads with air or other fluid to a determined extent. Or a
pressure gauge is attached to the inflator or to the pads to register the pressure of
the fluid contained therein.
Fig. 3 represents a measurement card or form which contains columns for
describing the position of the various parts constituting the gauge. The columns
shown are practically essential but naturally other columns or spaces may be used
as well for other particulars. The columns shown are for " right spring," "left
spring," "angle of right pad" "angle of left pad," "distention of right pad
"distention of left pad,' distention lining" "length of right terminal" " "length
of left terminal " strength of spring" "straps required left" "straps required
right" "quality."

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. A measuring gauge for hernia trusses consisting of two springs or bands
adjustably clamped together each band being provided with an adjustable pad
substantially as set forth.
2. A measuring gauge for hernia trusses consisting of two springs or bands
adjustably clamped together and provided with scales, each band being provided
with an adjustable pad having a scale marked thereon substantially as set forth.
3. A measuring gauge for hernia trusses consisting of two springs or bands
adjustably clamped together and provided with scales and an inflatable lining, each

page_text: band being provided with an adjustable and inflatable pad having a scale marked
thereon substantially as described and shown.
4. In combination with a measuring gauge for hernia trusses of the kind
described the employment of a scale on a pump or inflator to show the amount of
distention applied to the pads and lining substantially as described and shown.
5. The constructions shown on the drawings..
