PROVISIONAL SPECIFICATION.
Improved Means for Operating or Positively Driving the Feed
Apparatus of Carding Engines.
We CHARLES STOTT of 276 Oldham Road Machinist and WILLIAM HENRY
SCHOFIELD of 339, Oldham Road Machinist both of Rochdale and County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
Our invention relates to an arrangement for operating or positively driving the
feeding apron, brattice, or creeper of the feed apparatus of carding engines, but
this invention is more particularly adapted for and relates to the feeding apron,
brattice, or creeper of automatic feeding machines or apparatus such apparatus
as is well known being a separate and distinct machine from the carding engine
such apparatus being applied to or used in conjunction with carding engines.
The position of the creeper of such apparatus being vertically or nearly per-
pendicularly situate and it is found in practice that when dealing with or treating
wool or other fibrous material more or less of a strong or heavy nature, that the
creeper becomes at periods inoperative or stationary, whilst the driving shaft
continues its motion.
This invention is devised to obviate this evil and to provide a remedy therefor.
In accordance with our present construction we provide on the driving shaft two or
more serrated blocks or pieces at any convenient parts of the said shaft and
employed in conjunction with the leather bands, strips or foundation pieces to which
or upon which the "lags" or laths of the creeper are secured. On the underside of
the said bands we employ or attach thereto metal, wood, or other pieces or projections
suitably connected therewith and which pieces are arranged on the said bands at
equi distant parts such distances corresponding to the pitch of the serrations or
tooth like parts or projections of the said blocks consequently as the shaft rotates
the said projecting pieces on the bands gear with the said blocks and manifestly by
these means the creeper may be positively driven or operated and thus constant
and regular movement attained.
The ordinary blocks provided on the lower roller, or shaft not driven-the
creeper as is well known in such machines being stretched upon the driving shaft
and the lower roller-is suitably recessed at the parts over which the bands provided
with the projecting parts or pieces pass in order to allow or admit of the said
projecting parts or pieces to enter therein thus to allow the creeper to lie evenly
on the surfaces of the blocks carried by the said lower roller or shaft.

Improved Means for Operating or Positively Driving the Feed
Apparatus of Carding Engines.
We CHARLES STOTT of 276 Oldham Road Machinist and WILLIAM HENRY
SCHOFIELD of 339 Oldham Road Machinist both of Rochdale in the County of
Lancaster 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 :-
Our invention relates to an arrangement for operating or driving the feeding
apron or brattice of an automatic feeding apparatus used in connection with
carding engines

page_text: "
It is well known and found in practice that when dealing with materials
particularly such as are more or less of long staple or of a compressed or "matted
character that the creeper or apron of the feeding apparatus becomes inoperative
or operates irregularly whilst the driving shaft continues to revolve consequently
resulting in stoppage of the or irregular or unsatisfactory feeding.
Our invention has for its object to obviate this defect and thus to ensure
satisfactory or regular feeding of the material to the carding engine.
In order that our invention may be clearly understood we have reference to the
accompanying sheet of drawings in which like letters of reference indicate like
parts.
Figure 1. represents an elevation shewing our invention part in section applied
on the shafts of a feed apparatus for the purpose herein referred to.
Figure 2. represents an end elevation of Figure 1.
We provide on the upper or driving shaft a. two or more serrated or "tooth like "
drums or blocks bat any convenient part of the shaft as shewn in Fig. 1. a block being
provided in connection with each endless band c. to which the lags c¹ or foundation
of the apron is to be attached.
"
On the lower shaft g-the apron being stretched or mounted on the shafts a and g
as is well known-we provide thereon grooved or recessed blocks h. such blocks
being provided in connection with each band and opposite to the serrated blocks on
the shaft a. the number employed corresponding to the number of serrated blocks;
the recessed blocks are provided in order to act as carriers, the projecting parts
on the band--employed for a purpose hereinafter described-pass into the groove or
recess h¹, the recessed portion being adapted so as to allow of the admission therein
of the projecting parts d. obviating contact of the projecting parts with the blocks,
consequently allowing the bands when in motion to pass over the same uninter-
ruptedly, as the edges or sides only of the bands c are allowed to rest or ride upon
the flanged or projecting portions i. of the blocks.
On the bands c. we attach projecting parts or pieces d. by means of suitable
screw threaded pieces or screws c³, the said projecting pieces or parts are provided
at equi-distant parts of the bands being so adapted as to pass into the recessed
parts or engage with the projecting serrated portions e. of the blocks b, as the latter
are caused to revolve about the axis of the shaft f; consequently as the shaft
rotates, the "tooth like" projecting parts e. of the blocks bare caused to take hold
of the projecting parts d on the bands; the creeper or apron may by these means
manifestly be impelled forward or positively actuated or driven opposing any
resistance which may be created or occur, which may be due to the contact of the
' ordinary comb at which latter is well known with the material being fed
which may be more or less "matted" together or of a long staple, thus we are
enabled to effect or accomplish constant and regular movement of the creeper or
apron or accomplish regular feeding.
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
1. In combination the serrated or "tooth like" block b, the band c, provided
with projecting parts d. the recessed block h. substantially as and for the purpose
herein fully set forth.
2. In combination the serrated block with the band c. having projecting
parts d. as and for the purpose herein fully set forth.
3. The serrated block b'as and for the purpose herein fully set forth.
