for Cutting Double Pile Fabrics in Looms.
I WILLIAM MOSCROP of No. 10, King Street (South) Rochdale in the County of
Lancaster Cotton spinner 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:-
My invention relates to looms or machines for weaving pile fabrics, in which
machines, it is well known that simultaneous with the operation of weaving, the threads
which connect an upper and lower "web," are cut or operated upon by a sharp
instrument or edged tool, in such a manner, as to produce two separate cloths or
fabrics, known as "double cloth," one side of each cloth having a raised or pile
surface.
It is the object or purpose of this my said invention, to provide a contrivance
or arrangement which shall obviate the contact of oil used for lubricating the bearing
or working parts of the knife, or other extraneous. or objectionable matter, which
collects or deposits in and about the knife race and the traverse bar, with the lower of
the two cloths, which cloth, is caused to pass under the said bar, and being the portion or
part subjected to damage by oil known as "black oil," or other matter passing or falling
from the traverse bar, and which is of common occurrence in machines of the descrip-
tion herein referred to, often resulting in serious damage such as stains, thus
necessitating special treatment in order to remove such stains, which, in many cases
cannot be removed.
In order that my invention may be better understood, I have reference to the accom-
panying sheet of drawings, in which, like letters of reference indicate like parts
throughout the same.
Fig. 1. is an end elevation representing so much of a machine for weaving pile fabrics
as is necessary to illustrate my invention.
Fig. 2. is a plan thereof.
At or near the underside of the traverse bar A. hereinafter referred to as the "bar,"
at the upper part of which is situated a knife race B in which, the block C carrying a
knife D is caused to travel from one extremity E to the other F as is well known; I

page_text: apply a piece of metal or other suitable material G, of any convenient length, herein-
after termed "shield," in the longitudinal direction of the bar A, its outer sides H. H¹
being parallel with, and extending beyond the sides J and K of the bar, and are
curved see Fig. 1, which, with the sides J and K form channels I. I on each side of
the bar respectively, the extremities or ends L. L. of the shield G, particularly on the
side H, are suitably bent so as to press against, or engage with the side K. of the
bar A also to provide a passage I of convenient width, if desired, the shield G
may be
affixed to the said bar, or to any convenient part of the framing of the machine, in any
convenient manner as may be desirable, and as may be required, so that the same may
be situated below the bar A, in such a position, that any "black oil" or other matter
passing from the said bar over the sides J and K, may fall into or upon the shield G,
but as shewn in the drawings hereto annexed, the shield G is allowed to rest and is free
to move upon the surface of the cloth represented by the dotted line S, which is
caused to pass under the bar A, the shield G being prevented from passing away, or
out of contact with the bar, by the projecting portions M. M above the surface of the
shield G, the two cloths S. S as is well known being caused to pass under and over
the bar A. respectively, by the rotary actions of the taking up rollers N and N1, the
directions thereof being indicated in the drawings by the arrows, the lower cloth being
caused to travel in a direction from the bar A. over auxiliary rollers O. P. R.
It is evident that by applying such a contrivance as the shield G. at or about the
part as indicated in the drawings and herein described, any "black oil or other matter
that may pass out of the knife race over either side of the bar, or pass from the surface
of the bar, must be deposited in and retained by the channels I. I' formed by the
shield in manner as before stated, or must be deposited on the surface of the shield in
the case of the shield not being in close contact with the bar as the case may be, thus
the oil is prevented from falling on to the cloth travelling below, and the consequent
damage which would be caused by such an event being obviated.
Having now particularly described and ascertained the nature of my said invention,
und in what manner the same is to be performed, I declare that what I claim is.
The shield G having curved sides, or sides suitably directed, situated in contact with or in
any convenient position below the traverse bar A, its sides H. H' extending beyond the
sides J. and K. of the said bar, substantially as and for the purposes herein fully set
forth and described in the annexed drawings.
2. The use and application of a shield or guard substantially as and for the purpose
berein fully set forth and described in the annexed drawings.
Dated this 1st day of March 1887.
