Improvements in and relating to Machines for Beetling Yarn
and the like.
We, WILLIAM ROBERTSON, of the Firm of Hay and Robertson, Manufacturers,
St. Margaret's Works, Dunfermline, Fifeshire, and DAVID DOWNIE, Manager
to said Firm, and residing at Buffers Brae, Dunfermline, do hereby declare the
nature of our invention to be as follows:-
i
This invention has reference to a new or improved construction of machine for
beetling yarn for the purpose of softening it. It has preferably four beetles, but
can be made with as many as are wanted.
The
There is a crank overhead with connecting rods attached to beetles.
beetles work perpendicularly against a table that oscillates backwards and for-
wards by levers and eccentrics or equivalent gear. The beetles are in two parts.
The top part works inside the under part, on which there are four studs fixed
to upper part by four springs in order to minimise the shock of the blow. The
under part of the beetle that comes in contact with the yarn can either have a
plain or fluted face.

St. Margaret's Works, Dunfermline, Fifeshire, and DAVID DOWNIE, Manager

nature of our invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement in
writing that is to say;-

under part of the beetle that comes in contact with the yarn can either have a

And in order that our said invention and the manner of carrying same into
practice may be properly understood, we have hereunto appended a sheet of
explanatory drawings in which Figure 1 is a perspective view of the beetling
machine. Figures 2 and 3 are a front elevation and plan view respectively of
one of the beetles, and Figure 4 a sectional view corresponding to and looking
at right angles to Figure 2:
Referring to these drawings:--
The beetling machine is formed with side frames A stayed together and carrying
in suitable bearings A¹ a crank shaft A². Connecting rods B connect the beetles C
to the cranks on the shaft A2. This shaft A2 is driven direct from a belt a passed
over a fast and loose pulley a', and a hand wheel a² is fitted on the shaft so as to
turn same by hand and enable the operator to place the material to be treated
under the beetles.
An oscillating table D is mounted within the side frames A. of the machine,
and moves on antifriction rollers working within the grooves D¹, the table being
formed of a trough shape to receive and hold the yarn. The oscillating move-
ment is given to the table 1 by a lever D2 and connecting rod D³, said lever
being mounted on a rocking shaft D. This shaft D' receives the motion through
a lever and connecting rod d' having its top end mounted eccentrically on a
spur wheel, this spur wheel d² receiving its motion through spur gearing from
the pinion on the crank shaft A2. A pinion is mounted on a spindle c¹ and
gears with the wheel and a worm on this spindle c¹ gears with a worm
wheel or disc . This wheel is graduated to indicate by means of a stationary
pointer the number of reciprocations of table and beetles in the machine so that
the operator may know when the beetling action should cease. The table D is
fitted with rails e of wedge shape under-neath, the rollers on which the table
runs being mounted on these rails. Moveable wedges el are fitted to slide on
rails secured to the side frames of the machine, and are actuated by a screw
threaded shaft e³ operated by a hand wheel e, or by wheel gearing e when repeats
of the sets of beetles and table in the machine are used. These wedges e¹, raise
and lower or adjust the table to the level desired.
The beetles C are formed in two parts C1, C2, the top part C₁ working within
the lower part C². The two parts C1, C2, are connected together by preferably
four studs C3 and springs C, in order to minimise the shock of the blow of the
beetles, the studs being screwed into the top part C¹, and passes through the
web C on the lower part C2, and screwed by collars and pins C, leather washers
being preferably fitted between the collars and web. Slide guides E are formed
on the under part C2, these being formed with grooved and projecting surfaces on
opposite sides, so that all the beetles may work parallel. The under surface of
beetles which comes in contact with the yarn may either be formed plain, or
corrugated as shown.
Any desired number of repeats or lengths of this machine can be continued in
the same line.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
First. A machine for beetling yarn and the like constructed and operated sub-
stantially as set forth.
Second. A machine for beetling yarn and the like, having beetles formed in two
parts connected together by studs and springs, substantially as set forth..
Third. A machine for beetling yarn and the like having an oscillating table

page_text: operated by levers and mechanism substantially as herein described in reference to
and shown in the accompanying drawings.
Fourth. The arrangement in combination of the parts of a machine for beetling
yarn and the like substantially as herein described in reference to and shown in
the accompanying drawings.
