LETTERS PATENT to Captain William Michael Glynn Turquand, of 18, Denbigh
Place, Pimlico, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR SHEARING OR CLIPPING SHEEP AND OTHER ANIMALS."
PROVISIONAL SPECIFICATION left by the said William Michael Glynn Tur-
quand at the Office of the Commissioners of Patents on the 4th July 1876.
Captain WILLIAM MICHAEL GLYNN TURQUAND, of 18, Denbigh Place, Pimlico,
in the County of Middlesex. IMPROVEMENTS IN MACHINERY FOR SHEARING OR
CLIPPING SHEEP AND OTHER ANIMALS."
This Invention has for its objects improvements in machinery for shearing or
clipping sheep and other animals.
For this purpose I employ a tool which is guided by the hand whilst it is driven
from a rotating axis above by means of an endless clastic band of vulcanized india-
rubber.
The tool consists of a heavy metal driving pulley, around which the band passes;
the weight of this pulley serves both to keep the band distended and also to render
the motion uniform.
•
The pulley is able to turn freely on an axle, which prolonged forms the handle by
which the tool is held and controlled. The elastic driving band is guided on its
way to the pulley by small rollers mounted on two pairs of axes; one pair is parallel
to the axle of the driving pulley, and the others cross at right angles. The band is
kept within the space which is thus enclosed by the rollers. The rollers last
mentioned, namely, those at right angles to the axle of the driving pulley, are
divided each into two or three or more parts, and the parts (or they may be called
separate rollers) can revolve independently and in opposite directions as the band
comes into contact with them. The four axes of these guide rollers are all mounted
in a frame which is carried by and is free to turn about the axle of the driving
pulley.
The axle also has fixed to it the main frame carrying the fixed cutters and the
parts which actuate the moving cutter. This frame consists of a bar bent to the
form of three sides of an octagon.
The axle and handle project at right angles from one extremity of the frame,

page_text: whilst a number of cutters (say ten) are fixed to the other extremity and form a
continuation of that side of the frame. These cutters are arranged side by side like
the teeth of a comb, and a cutting blade moves to and fro over them. The fixed
cutters being separate the one from the other are able to spring sufficiently to keep
them in proper cutting contact with the moving blade as it passes over them. They
are sufficiently pointed to pass freely in amongst the wool, and in rear of the points
they are broader, so that they are in contact, or very nearly so, the one with the
other at the back of the sharpened or cutting part. This formation, together with
the thickness which is given to the base of the points, prevents the skin of the
animal protruding up between the fixed cutters. Behind the cutting portion again
these cutters become narrower, so that the wool cannot become jammed between
them. The fixed cutters are held fast to the frame by a screw clip, and shoulders
upon them prevent endway movement.
.
The moving cutter has a lancet-shape head sharp on both edges, or it may, if
desired, be formed with a number of cutting teeth; it vibrates about a pin fixed to
the frame, and its hinder end projects through a slot in the middle part of the frame
and enters between the jaws of a forked lever. This lever, which operates the
moving cutter, is itself caused to rock about a pin or stud fixed into the back of
the middle part of the frame; it receives motion from a spur pinion gearing with
another pinion fixed upon the driving pulley. The first-mentioned pinion has a pin
fixed into it eccentrically, and this pin is embraced by a fork at the upper end of
the lever, which, in the manner already described, works the moving cutter.
The form given to the frame brings the cutters considerably in advance of and
below the driving pulley, an arrangement which gives ample space for handling the
fleece.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Michael Glynn Turquand in the Great Seal Patent Office on
the 3rd January 1877.
Captain WILLIAM MICHAEL GLYNN TURQUAND, of 18, Denbigh Place, Pimlico,
in the County of Middlesex. "IMPROVEMENTS IN MACHINERY FOR SHEARING OR
CLIPPING SHEEP AND OTHER ANIMALS."
This Invention has for. its object improvements in machinery for shearing or
clipping sheep and other animals.
For this purpose I employ a tool which is guided by the hand whilst it is driven
from a rotating axis above by means of an endless elastic band of vulcanized india-
rubber.
The tool consists of a heavy metal driving pulley, around which the band passes;
the weight of this pulley serves both to keep the band distended and also to render
the motion uniform.
The pulley is able to turn freely on an axle, which prolonged forms the handle by
which the tool is held and controlled. The elastic driving band is guided on its
way to the pulley by small rollers mounted on two pairs of axes; one pair is
parallel to the axle of the driving pulley, and the others cross at right angles. The
band is kept within the space which is thus enclosed by the rollers. The rollers
last mentioned, namely, those at right angles to the axle of the driving pulley, are
divided each into two or three or more parts, and the parts (or they may be called
separate rollers) can revolve independently and in opposite directions as the band
comes into contact with them. The four axes of these guide rollers are all mounted
in a frame which is carried by and is free to turn about the axle of the driving
pulley.
The axle also has fixed to it the main frame carrying the fixed cutters and the
parts which actuate the moving cutter. This frame consists of a bar bent to the
forin of three sides of an octagon.
The axle and handle project at right angles from one extremity of the frame,

front view, and Figure 4 is a back view of a machine for shearing or clipping sheep
and other animals; it is constructed in the form which I prefer in carrying out my
Invention.
a is a metal driving pulley; it is of such a weight as to keep the elastic driving
band distended independently of any exertion on the part of the workman. b is
the axle, and the handle which is fixed to it; c is a bent plate fixed to the axis;
it serves as a frame to carry the working parts of the tool. d, d, are a series of
teeth forming a comb-like cutter, as represented in the Drawing; they are all of a
piece, but they may be made each tooth separately. This cutter is represented
separately by the Figures 5. c is the moving cutter; it consists in a lancet-shaped
head formed at the end of the lever e¹, which has its fulcrum at e². At c³ it projects
through a slot in the plate c, and here its end is embraced by a forked lever f,
having its fulcrum at f¹; the upper end of this lever is also forked, and it is made
to embrace an eccentric pin g¹ on the wheel g. This wheel is mounted upon a stud
fixed in the frame plate, and it gears with another similar toothed wheel h; the
tubular axis of this wheel surrounds the axle b, and upon it the band pulley a is
keyed. is a frame in which are mounted rollers to guide the driving band; k, l,
are two rollers parallel to the axle b, and at right angles to these are other rollers
,, and on one axis, and m¹, m², and m³ on another parallel axis, and these
rollers between them enclose a rectangular space by which the driving band passes
to and from the driving pulley so that the tool can be turned and inclined in any
direction as the workman may find most convenient without any risk of the driving
band escaping from the pulley. The frame is secured to the end of the axis and
also to the shield n which surrounds the pulley a; it has a hole through it at the
centre by which the axis of the tooth wheel / passes. o is a shield of thin sheet
metal bent to a suitable form; it serves to prevent the flecce getting entangled by
the working parts.
Having thus described the nature of my said Invention, and the manner of per-
forming the same, I would have it understood that I clain-

In witness whereof, I, the said William Michael Glynn Turquand, have here-

year of our Lord One thousand eight hundred and seventy-six.
