COMPLETE SPECIFICATION.
Improvements in Devices for Setting Broken Limbs.
We, NAZARETHI PAQUETTE, Physician, and HENRY NELSON PAQUETTE, Black-
smith both of Petersburg in the County of Mource and State of Michigan one of
the United States of America, 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:—
This invention has reference to a novel construction in a device for setting frac-
tured and dislocated limbs, and has for its object to provide a device of this
character, by means of which it is possible to set a fractured or dislocated limb
without assistance.

The invention consists in the features of construction hereinafter fully described
and specifically claimed.

In the accompanying drawings forming a part of this specification:
Figure 1 is

applied for setting a leg.
Figure 2 is a front elevation of the same.
Figure 3 is a perspective view of the instrument removed. In this figure certain
parts are broken away for convenience of illustration.
Figure is a front elevation showing the manner in which the device is applied
for setting an arm.

we have
In accordance with the principle involved by this invention we employ a device
consisting of two rods 1 that are connected together at their lower ends by a
cross piece 2. Near the connected ends of the rods is a winding dium 3, while
connected with the other end of one of the rods is a padded cross piece 4. In
using the device a strap 5 having a plurality of pads 6 is employed for attaching
the outer end of the limb to the winding drum, and in the drawings
shown these straps or bands, and the pads arranged for connection with the foot
or hand, whereby the instrument can be employed for setting the leg or arm.
We also employ a strap carrying pads 8 for the purpose of holding the leg or
arm in correct position between the rods. In employing this device the cross
piece 4 is placed against the groin or in the arm nit; and then the leg or the hand
is fastened by the strap 5 to the winding drum, and it is seen, therefore, that by
winding in the strap upon the winding drum, the limb is pulled to the correct
position, while at the same time the cross piece pushes upon the body, and in this
manner the limb can be readily set by one person only. It being noted, of course,
that the straps 7 and pads 8 are employed to hold the limb in position.
In the particular construction illustrated, the said winding drum is provided
with a pin 9 to enter the openings 10 in the ends of the straps 5, while the shaft
of the winding drum passes through the rods and is provided at one end with the
ratchet wheel 11 that is engaged by a spring actuated ratchet 12. In this way it

page_text: is seen that by means of the handle 13 the winding drum can be turned to
tighten the strap 5 to any degree, while the ratchet 12 can be moved to hold the
ratchet wheel or allow the same to rotate for the purpose of unwinding the strap.
The cross piece 4 is removably connected with the ends of the rods by means of the
bolt 14 passing through a socket 15 on the cross piece, and through an opening
in the end of the rod. As a further and separate improvement the rods are joined
at about their centres, for the purpose of shortening the device when it is desired
to transport the same. This construction consists of a pivot 16 between the
sections of the roa and the removable bolt 17, which passes through openings in
the end sections of the rod when said sections stand in alignment. The said rods
are also adjustable longitudinally whereby they are adapted for use in connection
with long or short limbs, and for this purpose each of the rods is constructed.
in sections 18, while one of the sections carries the pins 19 to enter openings 20 in
the other sections, and in this way it is seen the length of the rods can be easily
adjusted, while a shaft 21 carried by the sections carrying the pins 19 passes
through one of the openings 20 and by means of a nut holds said parts together.
It will be seen from the foregoing description that with a device of this kind a
person can set a fractured or dislocated limb without assistance, and furthermore,
the limb can be drawn to the desired length and easily held. Furthermore, the
device is reversible, so that the same instrument can be used for a right or left
limb, and also a device constructed in accordance with this invention can be used
for setting the arm or leg.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
:-
In a device of the class described, the combination of two parallel rods, each
consisting of a series of detachable and longitudinally adjustable sections, a cross
bar connecting the opposite sections of the rods at one end, a strap connecting the
adjoining sections of the rods at the opposite ends, a pad consisting of a socket
piece detachably connected with the terminal sections of one of said rods, and a
removable curved plate secured thereto and provided with padding, a winding
drum adjoining the connecting cross bar and provided with a pin or projection,
an attaching strap for engagement with the limb provided with openings adapted
to be engaged by said pin, and a series of straps provided with pads for holding
the limb in position, said straps being adapted for attachment thereto by means
of the attaching devices which adjustably connect the sections of the two parallel
rods of the device together, substantially as described.
