I FERDINAND FRIELINGHAUS of Voerde (Kreis Hagen) Westphalia; in the
Empire of Germany, Manufacturer, 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 and accompanying drawings :—
My said invention relates to instruments or apparatus for clipping or shearing
sheep and other animals and for removing wool or hair from the skins of animals.
And in order that my said invention may be fully understood I will now proceed
more particularly to describe the same with reference to the accompanying sheet of
illustrative drawings.
Fig. 1 of the drawings is a back view of the shears. Fig. 2. is a side view.
Fig. 3. is a view of the shears looked at from the points of the blades a. b. part of
the blade beds being shown in section. Fig. 4 is a view showing the arms 8. 8¹ of
the blade carriers in section. As shown in the drawings the blades a. b. are
separable from the carriers 8. 8. The said carriers are formed at the ends with
recessed beds w, w₁, the blades a. b. being laid upon the flat surfaces w. w¹ and
abutting with their ends against projections n, n, n¹ n¹. The blades a. b. are thus
in contact with the carriers both at the side and at the back and are thus firmly
bedded to the carriers. To secure the blades in position I employ screws e. e¹
which pass through countersunk holes in the cheeks w. w¹ and screw into the
blades which are thus firmly secured in their respective beds, the double contact
with the carriers rendering the blades immovable and obviating the necessity for
employing more than one screw to secure each blade in position. As seen more
clearly at Fig. 3. the abutments n. n. overlap each other in such a manner as to
prevent the shears from opening or being opened beyond the limit shown at Fig. 2.
The blade carriers or arms 8. 81 are of the semi-tubular section shown at Figs. 3.
and 4 and are connected at their outer ends by a flat spring p. secured to the
carriers 8. 8¹ by screws u, u as shown. The spring p. is bulged or curved in the
centre as indicated to give greater elasticity. The flat head of the arm 8. is of
greater area than the head of the other arm s¹ and is bevelled on one side as seen
at Fig. 1. so that when the connecting spring p. is applied, a space o. exists on one
side between the spring p. and the top of the arm 8. At this point I apply a

page_text: thumb screw i. which passes through the spring p. and screws into the head of the
arm 8. The object of this arrangement is to increase or diminish at will the
pressure of the edges of the blades a. b. against each other, an effect which is
produced by tightening up or relaxing the thumb screw i. I am thus enabled to
regulate the relative pressure of the blades according to the varying closeness or
weight of the wool or hair being clipped. The flat spring p. possesses advantages
over the ordinary curved connecting spring in the facilities it offers for this relative
sidewise adjustment of the blades, and also because it occupies less space than the
said ordinary curved connecting spring, so that large quantities of the shears with
flat springs can be packed for shipment within less space than is usually occupied
by goods of the same class. It will be evident that the spring p. could be attached
to the sides instead of to the tops of the arms s. 81, or that if desired a curved
spring could be used in conjunction with the other parts of my improved shears.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
(1.) In clips or shears of the indicated form bedding and attaching the separable
blades a. b. on and to the flat surfaces w. w' in conjunction with the abutments n, n,
n¹n the abutments n. n. overlapping each other so as to form stops which limit
the outward play of the shears, substantially as herein before described and shown.
(2.) The application of a flat spring p. to connect the two arms or blade carriers
of the shears, substantially as described and shown.
(3.) The means for adjusting the pressure of the shear blades against each other
consisting of the screw i. in conjunction with the spring p. applied and acting
substantially as hereinbefore described and shown.
