COMPLETE SPECIFICATION.
Obstetrical and Examination Stirrup.
I, JOSEPH MORGAN MAURER, of 59 West Wheeling Street Washington,
County of Washington, State of Pennsylvania, 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 :--
In the drawing annexed,
Figure 1 is a perspective view of one of the stirrups applied to the side-rail of
a bed;
Figure 2 a transverse section on line 2-2 of Figure 1, and
Figure 3 a longitudinal section of the rear portion of the stirrup.
The object of this invention is to provide improved stirrups adapted to be
applied to the side-rails of beds and to operating-chairs to assist the physician in
vaginal, womb and rectal operations and examinations as will more fully hereinafter
be described.
I have shown but one stirrup in the drawing but it is of course understood that
they are to be used in pairs. The letter a designates a bar curved upwardly at its
forward end, to form a foot-rest a', and downwardly at its rear end to form one
part, all, of a two part clamp, the bar being preferably formed rectangular in cross-
section. Clamped to the underside of the bar a, near the arm all, is a plate b,
which is wider than the bar and is slidably held thereto by a loop c and a bolt d".
The plate is slotted from its rear end forwardly, nearly its entire length, and the
two bifurcated parts thus formed are bent downwardly parallel to the part a",
to form the clamping jaws 10. The plate tapers in thickness towards its
forward end, and the loop c is secured near its rear end and adapted to closely but
not tightly, embrace the bar. The bolt passes down through a hole in the bar a
and through a slot in plate band is tapped into a plate or bar d extending across
the underside of the plate and tapered in an opposite direction thereto, said bar
being provided with a rectangular projection fitting up into the slot in plate b and
serving to assist in guiding and steadying the latter.
The stirrups may be clamped to the side-rails of beds or to a convenient portion
of surgical or other chairs. To secure the device to a bed-rail the part all is
placed against the inside of the rail with the bar resting on its top and projecting
outward from the bed; the sliding part is then adjusted up close against the rail
and securely clamped in place by screwing up bolt d". The patient lies crosswise
of the bed and places her feet in the stirrups, the latter being secured a convenient
distance apart.
It will be observed that this device is very simple and practical and is eminently
useful. The essential feature of the device is the manner of securing it to the bed-
rail. It will be seen that the oppositely-tapering plates and d (the latter being
clamped stationarily to the bar) prevent the clamp working loose when once the
bolt is screwed tightly. It will also be perceived that the slidable plate has but a
limited movement on the bar and cannot become displaced or out of position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination of a bar provided with a stirrup at its forward end and a
depending arm at its rear end a slotted plate secured to the bar near its rear end
and provided with a depending clamping-arm, a loop connecting the forward end of

page_text: the plate to the bar, a bolt passed down through the bar and the slot in plate b,
and a clamping plate on the lower end of the bolt, substantially as described.
2. The combination with a bar provided with a stirrup and a depending arm, a
plate b provided with a slot open at its rear end, said plate being provided with a
depending clamping-arm, a bolt passing down through the bar and the slot in a
plate, and a transverse clamping plate carried on the lower end of the bolt,
substantially as described.
3. The combination of a bar provided with a stirrup at one end and a clamping-
arm at its other end a slotted plate clamped to the underside of said bar and
provided with a depending clamping-arm, said plate tapering towards one end, a
clamping bolt passed down through said bar and plate, and a transverse clamping
plate on the lower end of said bolt, said plate tapering in the opposite direction
from said slotted plate, substantially as described.
Dated this 19th day of September 1893.
