PROVISIONAL SPECIFICATION.
An Improved Adjustable Device for use in connection with Surgical
Trusses.
I, JOHN MINCHIN WHITAKER of 41 Grafton Street, Dublin, Ireland, Physician,
and Surgeon do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved adjustable device for holding pressure pads
in connection with trusses for surgical purposes. In the ordinary device at present
employed the oscillating tongue, or plate to which the pressure pad is attached
rotates on a central pivot, and the mode of securing same at any angle is by means
of a pivot working in a curved slot in the free end of said oscillating tongue or
plate. The range of rotation of the tongue or plate is therefore limited to the
extent of the curved slot which is a disadvantage, and inconvenient in practice.
My invention is designed to obviate this inconvenience, and to this end, instead of
mounting the oscillating tongue or plate on a central pivot, I mount it on two pivots
or pins passing through a circular aperture formed at the base of the oscillating
tongue, or plate, and also through a stationary disk or washer placed over same, so
that the tongue or plate will be capable of rotating in a complete circle round a
fixed centre, while at the same time, means will be afforded whereby its adjustment
at any given angle can be secured at two intervals, and thus the pressure pad can be
conveniently arranged above, or below the truss as may be required, and the danger
of displacement is reduced to a minimum.

COMPLETE SPECIFICATION.
An Improved Adjustable Device for use in connection with Surgical
Trusses.
I, JOHN MINCHIN WHITAKER, of 41 Grafton Street, Dublin, 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 :-
This invention relates to an improved adjustable device for holding pressure pads
in connection with trusses for surgical purposes.
In the ordinary adjustable device at present employed, the oscillating tongue, or
plate to which the pressure pad is attached rotates on a central pivot, and the mode
of securing same at any angle is by means of a pivot, working in a curved slot in
the free end of said oscillating tongue or plate. The range of rotation of the
tongue or plate is therefore limited to the extent of the curved slot, which is a
disadvantage, and inconvenient in practice.
My invention is designed to obviate this inconvenience, and to this end instead of
mounting the oscillating tongue or plate on a central pivot, I mount it on two pivots
or pins passing through a circular aperture formed at the base of the oscillating
tongue, or plate, and also through two stationary disks, or washers placed under
and over same, so that the tongue or plate will be capable of rotating in a complete
circle round a fixed centre, while at the same time, means will be afforded whereby
its adjustment at any given angle can be secured at two intervals, and thus the
pressure pad can be conveniently arranged above or below the truss, as may be
required, and the danger of displacement is reduced to a minimum.

page_text: In order that my said invention may be more readily understood, I will describe
the accompanying drawings:
Fig. 1, represents the device ordinarily in use, and known as L'Estrange's
Patent;
Fig. 2, represents my improved device complete ;
Fig. 3, is a similar view with the upper disk (shown in Fig. 4) removed;
Fig. 5, is the lower disk.
In Fig. 1, it will be seen that the tongue or plate a, oscillates on the pivot a',
and that its rotatory movement is limited to the extent of the curved slot a².
In the arrangement of my invention the disk, Fig. 5, is first placed on the
plate b, and a margin round its edge being countersunk, the circular aperture of
the tongue c, is placed on same, whereupon the disk, Fig. 4, is laid over the tongue,
and the screws d, d, inserted. By this arrangement the tongue is free to turn on a
fixed centre, and to perform a complete circle as indicated by the dotted line
Fig. 2.
Thus the pad can be conveniently arranged at any convenient angle, either above
or below the truss, and its position secured by the two screws d, d, as well as by the
ordinary fixing screw e.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is.
In connection with surgical trusses, the use, and application of a device, constructed,
arranged, and operating substantially in the manner herein specified, and illustrated
in Figs. 2 to 5 inclusive.
