Improvements in Compressing Timber for the Manufacture of Shuttles, Bobbins, Teeth of Wheels, and the like.

Shuttles, Bobbins, Teeth of Wheels, and the like.
I, THOMAS PICKLES, of Cairo Mills, Burnley, Lancashire, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The improvements relate to compressing timber for the manufacture of shuttles,
bobbins, teeth of wheels, and the like, and have for object increased efficiency and
economy in such compressing, and form an improvement on Letters Patent
Number 15,125 of 1884 granted to Thomas Pickles and Benjamin Blakey.
In apparatus for compressing timber as at present employed, and as described in
the specification of the above cited patent, the blocks of wood to be operated upon
or compressed are placed in moulds or dies, fitted into a frame or frames, and acted
on by hydraulic or other power of sufficient magnitude, the metal sides and ends
of the moulds or dies coming in direct contact with the block or blocks of wood;
but experience shows that the pressure thus exerted distorts or deteriorates the outer
surfaces of the timber, rendering necessary the subsequent removal of a considerable
portion of such outer skin, which causes waste.
To obviate this evil, and to carry out my improvements, I place between the sides
or ends, or both, of the moulds or dies, and the surfaces of the wood block requiring
to be compressed, suitably shaped strips or separate pieces of wood, or other similar
yielding material, which act as buffers, and offer less rigid resistance to pressure
than does the metal of the moulds or dies.
The result is that the quality of the compressed timber is greatly improved, and
in addition the outer skin is not deteriorated nor distorted, to any objectionable
extent.
The precise character-as to relative hardness as compared with the compressed
block and also the shape, of the intermediate wooden strips or pieces may be varied,
without departing from the peculiar character of the invention.

-
The improvements relate to compressing timber for the manufacture of shuttles,
bobbins, teeth of wheels, and the like, and have for object increased efficiency and
economy in such compressing, and form an improvement on Letters Patent
Number 15,125 of 1884 granted to Thomas Pickles and Benjamin Blakey.
In apparatus for compressing timber as at present employed, and as described
in the specification of the above cited patent, the blocks of wood to be operated
upon or compressed are placed in moulds or dies, fitted into a frame or frames, and
acted on by hydraulic or other power of sufficient magnitude, the metal sides and
ends of the moulds or dies coming in direct contact with the block or blocks of
wood; but experience shows that the pressure thus exerted distorts or deteriorates
the outer surfaces of the timber, rendering necessary the subsequent removal of a
considerable portion of such outer skin, which causes waste.
To obviate this evil, and to carry out my improvements, I place between the
sides or ends, or both, of the moulds or dies, and the surfaces of the wood block
requiring to be compressed, suitably shaped strips or separate pieces of wood, or
other similar yielding material, which act as buffers, and offer less rigid resistance
to pressure than does the metal of the moulds or dies. The result is that the quality
of the compressed timber is greatly improved, and in addition the outer skin is not
deteriorated nor distorted, to any objectionable extent.
By this means it will be seen that the timber requiring to be compressed does
not come directly in contact with the metal sides of the die, and that the loose
strips or slabs of wood or other material intervening take up what may be described
as the first impact of pressure; and thus a more equable degree of pressure is com-
municated to the timber operated upon throughout its whole thickness than appears
to be the case with timber compressed directly by the sides of the metal die, as
employed by the method described in the specification hereinbefore cited.
I am aware that the compressing of wood in dies for the purpose of manufacturing
shuttles, bobbins, teeth of wheels, and the like in metallic moulds is not new, and
such, per se, does not form any part of this my present invention, which consists
in interposing strips or slabs of a somewhat yielding material, similar to wood,
to act as a buffer or buffers within the mould during the act of compression.
The precise character-as to relative hardness as compared with the compressed
block and also the shape and dimensions of the intermediate wooden strips or
pieces may be varied, without departing from the peculiar character of the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
In the compressing of timber for the manufacture of shuttles, bobbins, teeth of
wheels, and the like, the employment of strips or pieces of wood or other similar
yielding material in combination with moulds or dies, for the purpose and in
manner substantially as herein described.
