Improvements in the Process of Washing Fabrics and the Machinery
or Apparatus therefor.
I, DAVID MASON, C.E. of 212 Saint Vincent Street, Glasgow in the County
of Lanark Scotland do hereby declare the nature of this invention to be as
follows:-
This Invention has for its object to avoid abrading or destroying the cloth which
occurs by the present system of cylinder-washing Machines.
In such Machines up till now the folds of the material were arranged lengthwise,
which caused where formed broken places in the thread of material which it was very
difficult to avoid. I avoid this by arranging the folds crosswise since the material to
be washed is bound between the washing cylinders in all its width, or as it were,
passes between them in cross corrugations or folds, by the following Machinery or
Apparatus.
The Apparatus comprises two pairs of washer-cylinders between the periphery of
which the fabric is lead; the second pair having a slower circumferential speed than
the first and revolving in the same direction, the fabric or sheet is folded crosswise
between the second pair of cylinders; a set of small rolls or other feeding device
being placed between said pairs of cylinders.

or Apparatus therefor.
I, DAVID MASON, C.E. of 212 Saint Vincent Street, Glasgow, in the County
of Lanark, Scotland, 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, as communicated to me from abroad:
-
The new process on which my invention is based consists in this, that the sheet or
other tissue is brought in a folded state to the washing-cylinders, but in such a manner
that the folds are formed crosswise in the sheet.
In similar washing machines employed up till now they have worked the folds of
the sheet lengthwise, which has often caused breakings of the fibres of the tissue,
which were difficult to avoid.
In fig. 1, A, A and B B¹ are two pairs of cylinder-washers; T, T represents the sheet
intended to be washed, which, .entering between A A¹ is drawn by the cylinder W and
arrives at the pair of cylinders B B¹, of which the circumferential speed is less than
that of A A¹ and of W, consequently the sheet ought to place itself in folds on B¹
and pass in folds through B B.
The drum V serves to guide the sheet as it arrives from B B¹. The folds in the
sheet at its arrival in B B₁ disappear on its leaving BB¹.
It will be sufficient with some kinds of tissues to work them over one drum A
Figs. 2 and 3 instead of two as previously set forth, this said drum A having a greater
circumferential speed than the others B B¹.
For obtaining a more perfect washing in folds again, I have shown in Fig. 3 a
modified arrangement, in employing the cylinder compressor B2 which possesses the
same speed of rotation as the cylinder-washers B B', which, if necessary, one can use
in the same manner again as the other cylinders.
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.
1st. The process for washing clothes consisting in passing the tissue or sheet cross-
folded between a set of cylinder washers, substantially set forth.
2nd. The Apparatus comprising a system of washing cylinders or drums, substantially
arranged and operating as described and shown.
