PROVISIONAL SPECIFICATION.
A Combined Bed Elevator and Extension Apparatus for Use in
Surgical Operations and for other similar Purposes.
I ADAM SLOAN, of 9 Fisherwick Place, Belfast in the County of Antrim Anatomical
and Orthopedic Mechanician, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a combined bed elevator and extension apparatus for use in
surgical operations and for other similar purposes and bas for object to construct such
apparatus in the manner described in the following specification.
My invention consists of a framework of tubing, consisting of two supports resting
on metal feet, said supports being hollow.
Running inside of each support is a tube connected by a cross bar.
Those tubes are perforated with holes at certain distances for the reception of bolts
acted upon by springs. These bolts and springs are acted upon by a lever upon
which the surgeon or assistant, places his foot. From the lever, there is a cord passing
over pulleys and attached to each bolt. By pressing the foot down, the cord is acted
upon and pulls the bolts back, then the cross bar connecting perforated tubes can be
raised and the bolts shoot into position, sustaining cross bar that much higher. In
the upper end of each perforated slide is a notch for foot rail of bed to rest in, so
that in raising cross bar you raise bed also.
From the connecting tubes which hold the first frame work together, rises a per-
pendicular tube which contains another sliding tube which is acted upon by a pinch
Screw to hold it at whatever height it is required.
Upon top of same tube is a brass head containing slot for angular bar to pass back-
ward and forward in said bar, hold in place by two thumb screws.
Said bar on its lower arm supports another brass swivel with pulley. Said brass
head is also secured by thumb screw. The pulley is for cord to pass over, connecting
weight with patient.

A Combined Bed Elevator and Extension Apparatus for Use in
Surgical Operations and for other similar Purposes.
[ ADAM SLOAN, of No. 9 Fisherwick Place, Belfast, Anatomical and Orthopaedic
Mechanician, 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 a combined bed elevator and extension apparatus for use
in surgical operations and for other similar purposes, and consists of a tubular frame-
work composed of two hollow supports resting on metal feet.
Within each support is arranged a tube capable of moving up and down these tubes
being connected by a cross-bar.
Said tubes are provided with perforations at suitable intervals for the reception of
bolts actuated by a cord passing over a pulley and set in motion by means of a treadle
upon which the surgeon or his assistant places his foot when releasing the said
bolts.
From the central cross tube which connects the framework together, rises a vertical
tube which contains a sliding tube fixed therein by a screw so that it can be held at
any suitable height.

page_text: Upon the top of the same tube there is arranged a brass head provided with an
opening or slot through which passes one end of an angular bar, secured therein by
a thumb screw.
The other end of the said bar carries a frame fixed thereto by a thumb screw
in which frame is mounted a pulley. Over said pulley passes a cord, one of
whose extremities is fixed to a weight while the other exerts a tension upon a block
fixed to the patient's foot.
And in order that my invention may be more fully understood, I have shewn the
same in the accompanying drawing in which Fig. 1 is a front elevation of my improved
apparatus applied to the end of a bed stead and to the foot of a patient.

My improved apparatus consists of a tubular frame composed of two tubular
uprights fixed to the feet f.f" which are connected together by a cross bar b. The
uprights u. u are connected near the top by a cross tube t from the centre of which
rises a tubular holder within which a rod y slides up and down and is furnished at
the top with a perforated cylinder through which passes one end of a bar a twice

carries a screw frame d supporting a pulloy around which passes one end of a
cord c which is fixed to a block e fastened to the patient's foot as shown in Fig. 1.
The lower extremity of this cord carries a weight to hooked thereto.
At both ends of the cross tuhet are fixed two frames g. g carrying two bolts n. n¹
bent at their inner ends which are attached to the ends of a cord looped around a
pulley. To this loop is attached another pieco of cord likewise looped, in which is
fixed the end of a hook i whose other end is secured to a treadle articulated to the
cross bar b. These bolts n. n' are provided with spiral springs within the span of the
frames g. g and their outer ends enter perforations m. m &c. formed at suitable
intervals in the body of the two tubes o. o¹, sliding within the uprights u. u¹ and
carrying suitable tubular heads q notched inside and in which are securely inserted
the two ends of the cross raif which has to support the bottom rail of the
bedstead B.
The block e is fixed to the foot F of the patient, laying for the purpose upon
the bod A, by means of strips of adhesive plaster and bandages saitably buckled
thereon, one end of the pulley cord e being attached in any suitable manner to the
block e.
The surgeon placing his foot on the treadlo withdraws the spring bolts n. n
from their respective perforations and raises the tubes o. o¹ and the rail to the
desired height. Withdrawing now his foot from the treadle and thus allowing the
bolts to be shot home, he raises the bed rail and places it upon the rail, and in
the notches of the heads q. q'. He then raises the rod y to the required height and
fixes it in position by means of the screw s.
The end of the cord e being finally attached to the block e, the weight wo will
henceforward exert a constant tension upon the patients foot, which tension may be
increased or decreased at will by hooking heavier or lighter weights to the lower end
of the cord c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I doclare that what 1
claim is :-
The combined extension apparatus and bed elevator for use in surgical operations
and other similar purposes, arranged, combined, and operating substantially as and for
the purpose described.
