Improvements in Beetling Machines.
We, WILLIAM JAMES MATHEWSON of 234 Shankill Road Belfast Ireland
Engineer and JOHN WATSON of 1 Springfield Villas Springfield Road Belfast
aforesaid Engmeer do thereby 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
-
Our invention relates to beetling machines for finishing fabrics and has for its
object to increase the durability of such machines and to prevent the fabric
operated on from being cut or damaged by the beetling lammers. According to
Our invention we construct the shank of the beetling hammer and the guides in
which it slides of such a shape as to ensure the hammer acting square on the
fabric or in a direction so as not to cut or damage the fabric. To further ensure
the proper action of the hammer, the wearing surfaces in the guides or the
guides which carry the said wearing surfaces can be adjusted in position so as to
compensate for wear The wearing surfaces can be fitted to the guides so as
to admit of them being removed when woin and replaced by new wearing
surfaces.
And in order that our invention may be fully understood we shall now proceed
more particularly to describe the same and for that purpose shall refer to the
guies on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in both figures
Figure 1 is a sectional elevation of so much of a beetling machine as is necessary
to illustrate our invention and
Figure 2 is a horizontal section taken along the line 1-2 Figue 1.
A is the hammer head the stem A³ of which is formed with rectangular ribs or
projections a which enter and slide in corresponding recesses or guides formed in
brackets B adjustably secured to a block D, carried on the 1od E which is operated
by the crank of the beetling machine in the usual manner. The recesses or guides
in which the stem A³ of the hammer works are formed of or faced with strips b²
of a material that does not require to be lubricated and which will prevent the
formation of metal dust such for instance as lignum vitæ or other like hard wood,
the said strips & forming the wearing surfaces being inserted and held in position
in recesses formed in the brackets B and capable of being removed when worn and
replaced by new strips. The brackets B are secured to the block D by bolts c
assing through slots d aud screwing into holes in the block D. From the
block D project lugs having tapped holes therein for the reception of screws F
the ends of which screws bear on the brackets B so that when the wearing surfaces
of strips become worn, and the stem A of the hammer becomes loose therein,
the brackets B together with the strips can by means of the screws be forced
inwards and ensure the hammer working without vibration or twisting. Instead of
making the brackets B adjustable the wearing surfaces or strips b² may be
adjustable the brackets by providing the said brackets with adjusting screws
to act ou the back surface of the said stups.
Although we have shewn the stem of the hammer block as having rectangular
ubs we do not restrict ourselves to this form, as the stem may be of oval polygonal
on of any other suitable form, and work in guides of coresponding shape to
prevent the turning of the stem in its guides and ensure it acting squarely on the
fabric.

page_text: In tlie brackets B are holes through which pins or studs can be passed into
recesses in the stem A² of the hammer to hold the hammer out of action when
required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
-
1st. In beetling machines the hammers of which slide in guides, the application
and use in the said guides of strips of material which does not require lubricating
such for instance as lignum vitæ or other like hard wood whereby cleanliness and
absence from metal dust is ensured substantially as herein before described
2nd. The combination with the subject matter of the preceding claim, of screws
for adjusting the position of the brackets carrying the weating sui faces against
which the stem of the hammer works or for adjusting the wearing surfaces in the
brackets substantially us and for the purpose hei einbefore described.
3rd. Constructing the shanks of beetling maclune hammers of a shape other
than cylindrical, and the guides in which they work of corresponding shape so as
to prevent the hammers from turning in the guides and ensure them acting in
the required manner to prevent cutting or damaging the fabric operated on
substantially as herein before descubed
