PROVISIONAL SPECIFICATION.
Improvements in or connected with Rasps, Files, or other
Instruments Used for Veterinary Purposes.
I, JAMES ERNEST ARNOLD of 31 West Smithfield, in the City and County of
London, Surgical and Veterinary Instrument Maker, do hereby declare the nature
of this invention to be as follows:-
My invention refers to instruments used for veterinary purposes known as
"tooth rasps," but applicable to other purposes than for filing or rasping the teeth
of horses.
The primary object of the invention is to provide simple, but effective means
for holding such rasps, or other instrument, as the above named, in position, during
the operation, as well as the provision of very simple means for changing the rasp,
file, or other instrument, in accordance with the work to be performed, or when the
rasp, file, or other instrument, is worn.
According to my invention, I construct a frame of a shape to correspond with
that of the rasp, file, or other instrument binged or jointed, and provided with
shanks, inserted and held in, or forming suitable handles, for securely and firmly
holding the tool. The lateral sides of the frame are grooved, to receive the rasp,
file, or other instrument, when the handles are separated, so as to allow of the rasp,
file, or other instrument, being inserted in the grooves; or the rasp, file, or other
instrument, may be grooved at the side, and the frame made to fit into the grooves.
The closing or bringing together of the handles, keeps the rasp, file, or other
instrument, tightly held in position, with or without the addition of other holdfasts
being applied to the handles. The edges of the rasps, files, or other instruments,
may be flush with the roughened surface, or the latter may be raised, so as to be
flush with, or to project above, the edges of the frame.
By my invention the rasps, files, or other instruments, are held firmly without
any outside aid, such as screws, which only weaken the tool, whereas by simply
placing the rasp, file, or other instrument, in the frame, and closing the latter, it is
then secure, and ready for use, while a rasp, file, or other instrument, can be
changed, by simply opening the handles, withdrawing the rasp, file, or other
instrument, and inserting another, of whatever form required.

Improvements in or connected with Rasps, Files, or other
Instruments Used for Veterinary Purposes.
1, JAMES ERNEST ARNOLD, of 31 West Smithfield, in the City and County of.
London, Surgical and Veterinary Instrument Maker, 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 refers to instruments used for veterinary purposes known as

page_text: tooth rasps, but apprca orе to other purposes than for filing, or rasping the teeth
of horses.
The primary object of the invention is to provide simple, but effective means for
holding such rasps, or other instruments as the above named, in position, during
the operation, as well as the provision of very simple means for changing the rasp,
file, or other instrument, in accordance with the work to be performed, or when the
rasp, file, or other instrument, is worn.
In order that my invention may be readily understood I will describe same with
reference to the accompanying drawings on which similar letters of reference
indicate like parts in the several figures.
Fig. 1 of the accompanying drawings is a front, and Fig. 2 a side elevation of a
rasp or file for veterinary purposes, constructed according to my invention.
Fig. 3 is a front elevation of the jaws or rasp-holding portion of the instrument.
Fig. 4 is a plan view of the rasp or file proper detached, and Fig. 5 is a cross
section of same shewing the rasp or file held by the jaws.
According to my invention, I construct a frame A of a shape to correspond with
that of the rasp, file, or other instrument B, hinged or jointed at C and provided
with.shanks D, inserted and held in, (or forming) suitable handles E, for securely
and firmly holding the tool. The lateral sides of the frame are grooved, as
indicated by the dotted lines in Fig. 3, to receive the rasp, file, or other instrument B,
which latter is inserted when the shanks D are separated, and in the position shewn
at Fig. 3, so as to allow of the rasp, file, or other instrument B, to enter in the
grooves; or, although not so shewn in the drawings the rasp, file, or other
instrument, may be grooved at the side, and the frame made to fit into the grooves.
The closing or bringing together of the shanks D, keeps the rasp file, or other
instrument B, tightly held in position, with or without the addition of other
holdfasts being applied to the said shanks D. The handle shewn at Figs. 1 and 2
is formed with a socket and slot E, and has a pivotted lever E having a bent end
taking into the slot. a a Fig. 3 show recesses cut in the shanks D into which the
catch or hook or bent end on the pivotted lever E' is caused to take and thereby
hold the shanks D to the handle portion E, or any other convenient construction
of fastening may be employed, as desired or required.
The edges of the rasps, files, or other instruments, may be flush with the
roughened surface, or the latter may be raised so as to be flush with, or project
above, the edges of the frame A.
By my invention the rasps, files, or other instruments are held firmly without
any outside aid, such as screws, which only weaken the tool, whereas by simply
placing the rasp, file, or other instrument B, in the frame A, and closing the latter,
it is then secure, and ready for use, while a rasp file, or other instrument, can be
changed, by simply opening the handles, withdrawing the rasp, file, or other
instrument, and inserting another, of whatever form required.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In rasps, files, or the like instruments used for veterinary purposes, the
construction and arrangement of tool holding frame hinged or jointed centrally as
shewn, having grooves to receive the rasp, file, or the like, with shanks or tail
pieces connected to or formed with the holding frame proper, in combination with
an operating handle to receive, hold, and retain the tool frame, (by locking catches
as shewn) whereby rasps or files of varying sizes and varying degrees of fineness
may be fitted and retained or changed as may be required, and when not required
for use, be packed away into half the space as when opened out for use, all
substantially as herein before described and illustrated with reference to the
accompanying drawings.
2. In rasps, files, or the like instruments, used for veterinary purposes, the
construction and arrangement of tool holding frame, hinged or jointed at or near

page_text: one end, and a rusp, file, or other instrument, grooved at the sides or edges, so
that the hinged frame when closed, embraces and takes into such edges, in
combination, or not, with a socketted handle, substantially as and for the purposes
described.
