PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Operating the
Healds in Looms for Weaving.
We, JOHN FREDERICK ROUSE, and HERBERT ROUSE, of the firm of William
Rouse & Co., of North Brook Mills, Bradford, in the County of York, Spinners and
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the operation of the healds in looms for weaving
in such a manner, that the motion imparted to the same is positive, and practically
free from the common and well known irregularities in the motion of the healds when
springs or other apparatus now in.common use are connected to the bottom shafts of
the same; also to retain a more equal tension on the healds in all positions than is
the case when springs or other ordinary apparatus are employed.
It is well known to persons conversant with weaving, that with some classes of
goods, any irregularity in the motion of the healds produces defects in the fabric,
which are especially noticeable in goods of light texture, worsted coatings, and pile
fabrics; and that so long as the healds can be operated with regularity, these defects
are nil.
We accomplish our object in the following manner-We mount a series of tappets
on what is commonly known as the bottom shaft of the loom, or in any other
convenient position, and which operate treadles that may be connected to the jack
rods and upper heald shafts in the usual manner. Beneath the healds we place
an additional shaft which may be run at the same, or at an equally divided
proportionate speed to that of the tappets that are in connection with the top heald
shafts.
On the additional shaft we mount another series of tappets with the perepheries so
arranged, that the swells on one series of tappets are represented on the other by
recesses. The additional tappets operate treadles which are severally connected to
intermediary levers, and these levers to the respective healds, so that by these means
the healds are always at the same degree of tension, and whenever the tappets operate
any of the treadles, the healds are operated accordingly.

which are especially noticeable in. goods of light texture, worsted coatings, and pile
fabrics, and that so long as the healds can be operated with regularity these defects
are nil.
We accomplish these objects by mechanism illustrated in the accompanying
drawings in which Fig. 1. represents an end view of an ordinary type of loom to
which our invention is applied.
Fig. 2. a back view showing how our improvement may be placed.
Fig. 3. a plan of the same through line X. X.
Fig. 4. is a transverse section through a loom showing our additional mechanism
mounted in a modified form, part of the driving wheel being cut away to more clearly
illustrate the tappets.
Fig. 5. is a detail showing the connections between the treadle levers and bottom
heald shafts, and
Fig. 6. is a sectional plan of Fig. 4. through lines Z. Z.
Similar letters refer to similar parts throughout all the views.
We mount a series of tappets A. on a long sleeve B. forming part of spur wheel C.
driven in the usual manner from the crank shaft C' by a train of spur gears, the
tappets A. operating the respective treadles D. which are severally coupled by bars E.
to the jack rod levers F. mounted on bars on which are also mounted quadrants F¹
coupled by cords or other suitable connections to the top shafts of the healds H. The
wheel C. having the long sleeve B. on which the tappets A. are secured is free to
revolve on the shaft G. which is driven in the usual manner, so that the wheel C. and
attachments thereto may revolve in the same or opposite directions. So far all the
parts described are old and well known, for which no claim is made as forming part
of this invention.
On what is generally termed the "bottom shaft" G. of the loom, we secure a
pinion J. which meshes with spur wheel J' mounted on shaft K. on which is
secured a bevel wheel L. meshing with wheel L' secured on shaft L' on which
are also secured a series of tappets A¹ the geared wheels being so arranged, that
the shaft L will make exactly the same number of revolutions as the wheel C. and
tappets A.
Below the tappets A' are mounted a series of additional treadle levers M. each of
which is connected to a bottom shaft H' of the healds; the peripheries of the two
series of tappets A and A' are so arranged that when the swells S. of one series press
the respective treadles for operating the healds in one direction, the recesses in the
other series allow the corresponding treadles to move towards the shaft on which the
tappets are mounted, thereby giving positive motion to the healds whenever any of
the swells S. operate any of the treadles in either direction, the tension on the healds
remaining practically the same in all positions.
The additional tappets A¹ may be mounted in a modified form as shown by Fig. 4.
on a shaft N. placed below and parallel with the bottom shaft G. in which case the
pinion J. is also secured thereon, by preference meshing with wheel (by an inter-
mediate wheel P. the treadle levers M. mounted below being coupled to the respective
heald shafts H¹ by rods R. to the intermediary levers T. and the latter by rods or
cords R¹ to the heald shafts H¹ at such distances from the pin U. supporting the
intermediary levers T. that the motion or traverse of all rods or cords R is the same,
thereby retaining an equal tension on the healds in all positions, and ensuring a
positive motion of the same.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
In a loom for weaving fabrics, a series of tappets A. operating treadle levers D:

additional levers M. connected either directly or through intermediary levers T. to
the bottom shafts H¹ of the healds, all substantially as set forth.
