PROVISIONAL SPECIFICATION.
Improvements in Cropping-machines or "Perpetuals" employed for
Shearing Hearthrugs, Carpets, and other like Fabrics.
I, JOHN BEEVER, of Huddersfield in the County of York, Hearthrug Manufacturer,
do hereby declare the nature of this invention to be as follows:-
In this class of machine it often happens, when introducing the end of a hearthrug
or other fabric into the machine that the revolving spiral cutter lifts up the end of the
hearthrug in such a way as to be damaged by the revolving cutter, and the same
applies when the opposite end of the heartbrug is leaving the machine. The object
of my invention is to prevent the revolving spiral cutter damaging hearthrugs,
carpets, and other like fabrics when being sheared; and in carrying out my invention
I place close to the underside of the cutting edge of the revolving cutter a number of
wires arranged transversely or at an angle to the axle of the said cutter. The carpet
or rug to be operated upon travels underneath these said wires which prevents the
edge of the fabric being drawn up by the cutter, and as the wires are fine they form
no impediment to the proper shearing of the rng as the said wires sink or are
depressed into the pile of the fabric, allowing the hearthrug to be pressed close up to
the edge of the cutter. Each wire is attached to a thumbscrew arranged in suitable
framework, so that the tension of the said wires can be regulated. The wires may be
made of copper, of steel, or any other suitable material.

COMPLETE SPECIFICATION.
Improvements in Cropping-machines or "Perpetuals" employed for
Shearing Hearthrugs, Carpets, and other like Fabrics.
I, JOHN BEEVER, of Huddersfield in the County of York, Hearthrug 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:-
In this class of machine it often happens when introducing the end of a hearthrug
or other fabric into the machine that the revolving spiral cutter lifts up the end of the
hearthrug in such a way as to be damaged by the revolving cutter, and the same
applies when the opposite end of the hearthrug is leaving the machine. The object
of my invention is to prevent the revolving spiral cutter damaging hearthrugs,
carpets, and other like fabrics when being sheared; and in carrying out my invention
I place close to the underside of the cutting edge of the revolving cutter a number of
wires, forks or fingers arranged transversely or at an angle to the axle of the said
cutter. The carpet or rug to be operated upon travels underneath these said wires,
which prevents the edge of the fabric being drawn up by the cutter, and as the
wires are fine they form no impediment to the proper shearing of the rug but allow
the hearthrug to be pressed close up to the edge of the cutter. Each wire is attached
to a thumbscrew arranged in suitable framework, so that the tension of the said wires
can be regulated. The wires may be made of copper, of steel, or any other suitable
material.
Such being the nature and object of my invention, I will now, in order that the
same may be more fully understood, make reference to the accompanying sheets of
drawings illustrative thereof, wherein Fig. 1, is cross section of such parts of a
cropping machine or "perpetual" as is necessary to illustrate my improvements

page_text: therein, and Fig. 2 is plan view of the same. A represents the framework of the
machine, B the revolving spiral cutter carried in the moveable headstock C, and D is
a revolving roller for carrying the hearthrug or carpet forward whilst being operated
upon, all constructed and arranged in the ordinary manner. E represents a hearth-
rug, a being the back thereof, and 6 the pile of the fabric. My improvements are
shewn at F, comprising a series of metal wires forks or fingers fixed at one end to the
rail or plate G by means of rivets or set screws c, the opposite end of such wires
being connected to a "bat wing" nut d operated backward or forward so as to
regulate or adjust the tension of the wires, by means of thumb screws e which pass
through the said nuts d. The fabric to be operated upon passes under the grate or
crosswires F so that when the end of the fabric is introduced underneath the revolving
cutter, these crosswires prevent the end of the fabric rising above them, also when the
opposite end of the fabric is leaving the cutter it is prevented from rising by the said
crosswires, consequently the damaging of the carpet by being cut at each end is now
prevented, a considerable saving being thereby effected.
In Fig. 3, I have shewn that the crosswires F, instead of being arranged at right
angles to the cutter, as shewn in Fig. 2 may be placed at any other suitable angle.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In machines for cropping or shearing hearthrugs and other fabrics, the
combination there with of crosswires forks or fingers such as F employed in the
manner specified and for purposes set forth.
Secondly. In machines for cropping or shearing hearthrugs and other fabrics, the
combination therewith of crosswires such as F, together with means for adjusting the
tension thereof, in manner substantially as herein shewn and described.
