PROVISIONAL SPECIFICATION.
Automatic Combined Fast and Loose Reed Action for Power Looms.
1, JULIUS HALL, of 80-81 Strand in the County of Middlesex, Patent Agent, do
hereby declare the nature of this invention, a communication to me from abroad by
Amos Lockwood of Meerane, in the German Empire, Engineer, to be as follows:-
This invention has for object to render practicable and convenient the weaving in
the same loom of light and heavy goods of different classes, this object being attained
by an automatic engagement and disengagement of the locking pins of connecting
levers or rods by which the loom may be alternately converted into a fast reed loom
and loose reed loom.
A cam fixed on a crank shaft communicates an oscillating motion to a pivotted lever,
the end of one arm of which has a projecting part which in the oscillations in one-
the inward-direction of the said lever, comes against a bar carried on a second shaft
which may be termed a slide shaft. This, when contact or engagement is effected, is
caused by reason of the action of the cam and consequent oscillation of the lever to
slide laterally carrying with it a number of arms fixed thereon fitted with steel pins,
so as to disengage these from the reed locks and thereby convert the loom from a fast
into a loose reed loom. As soon as the bar on the slide shaft has got to the end of the
stroke communicated to it by the oscillating lever a helical spring on the slide shaft
brings this back again so as to re-engage the locking pins in the reed locks to convert
the loom from a loose reed into a fast roed loom until the oscillating lever is brought
to perform another inward stroke so as to come again in contact with the bar fixed on
the slide shaft, and so on.
During the loose reed action the reed holder is held in position by a spring.

Automatic Combined Fast and Loose Reed Action for Power Looms.
1, JULIUS HALL, 80, now of 95 Strand in the County of Middlesex, Patent Agent,
do hereby declare the nature of this invention, a communication to me from abroad
by Amos Lockwood of Meerane, in the German Empire, Engineer, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement, that is to say :-
ki
It relates to mechanism to be employed in connection with a loose, swing or
moveable reed power loom for the purpose of locking or firmly and rigidly holding
the reed during the performance of that part of said reed's functions known as
beating in the wett," the same mechanism allowing said reed to be freely operated
during any other portion of its movements for effecting any of the well known objects
or requirements of a loose reed power loom and this invention consists of so constructing
and arranging this mechanism that the object of locking and releasing said reed in the
manner described is performed with greater precision or certainty than is the case
with most of the mechanisms heretofore employed while the cost of production of same
is comparatively small.
In order that my said invention may be more readily understood I will proceed to
describe same by reference to the accompanying sheets of drawings forming part of
this Specification, Figs. 1 and 2 of which are sectional front and top views of a portion
of a power loom shewing the application of my invention.
Figs. 3 and 4 are end and sectional end elevations of parts shewn by Figs. 1 and 2.

page_text: Fig. 5 is a similar view to Fig. 2 but shews a modification in the formation of the
parts for operating the locking mechanism.
1 attain the object of my invention by hinging the lock-bolts a to the reed's
holding-piece b (this said holding-piece b being maintained in its position for pressing
or keeping the reed in an ordinary way in position by means of the well known spring
arrangements at present in use) and arranging these bolts a to extend through the lay
so that an opening d, made in each of them, may be presented for the reception of the
tapering pins c which are forced therein by being mounted upon the sliding rod
operated by the spring g; thus said rod f being operated in the other direction by the
motion of the lay c, bringing the end of the guide piece h (which serves as a guide
and holder to prevent any rotary movement on the part of the rod f) into contact with
the cam-plate k mounted upon the lever 1, and this said cam-plate k is raised into
position for contact with said piece ¹ by means of the cam or tappet m mounted upon
the rotary shaft n, while its return movement is effected by the spring o.
The cam m is arranged to operate the lever at the proper time relatively with the
time of movement of the lay e so that the cam-plate k is raised into the path of motion
of the piece h¹ to cause said piece ¹ to move and liberate the lock bolts a during the
whole time occupied by the passage of the shuttle across said lay c, while when
the piece has moved clear of the plate by the continued movement of the lay c the
tapering pins e are freed and moved to enter their respective holes or openings d thus
locking or rigidly holding the reed by its holding piece b.
In place of the cam plate k and its operating mechanism, a slotted rod p may be
einployed for operating the sliding-rod f and its tapering pins e by or from the
oscillatory movement of the lay c. The said rod p is hinged to the piece has also to
the fixed pins so that as the lay c recedes from the pins the rod f is forced in the
direction indicated by the arrow t, while when it approaches the pins the spring g
effects the return movement of the rod f until the tapering pins e have entered their
respective openings, and as said lay c continues this movement for finally beating in
the weft the slot p₁ in the rod p allows said rod p to be carried beyond the holding
contact of the pin s.
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.
1. In reed locking mechanism the combination of the lock-bolts a, the pins e of the
shape described, the sliding rod f, the spring g, the guide piece h, the cani-plate k, the
lever 1, the cam m and the spring o substantially as specified, each one and all of said
parts being formed and arranged to operate to effect the object described in the manner
as herein set forth.
2. The combination in reed locking mechanism consisting of lock-holts secured by
tapering pins mounted upon and operated by a sliding shaft such as the shaft f, of a
slotted rod, as the rod p, and means for holding or carrying same substantially as
herein specified.
