Machine Maker, do hereby declare the nature of this Invention to be as follows:-
The chief object of my Invention is to obtain a positive strong and steady shuttle
box motion.
In applying my Invention to a loom with several shuttle boxes on one side only
I employ an ordinary pattern chain with holes for actuating the cock heels or pegs
which govern the shuttle box motion. The star wheel and pattern chain barrel are
caused to turn intermittently as usual by a plate wheel mounted on a short shaft
driven from the crank shaft. Now according to my Invention I combine with this
motion a rising and falling motion for the star wheel and barrel and this I effect by
means of a cam secured on the short shaft which cam acts upon a bowl mounted on
a lever one end of which is secured to the axle of the star wheel. When the star
wheel is at the bottom it is turned by the plate wheel and in its upward movement
the chain acts upon the cock heels and their levers. On the lower end of each pivoted
cock heel lever is mounted a spur wheel with a blank space on its periphery and to
an eccentric stud on each of these wheels is connected one end of a long lever which
is connected at the other end to the bottom levèrs which operate the shuttle box.

of its periphery and formed with or secured to a pinion; these two pinions are geared
together by two carrier pinions and the first pinion is driven intermittently by a
segmental wheel cast with or secured to the driving wheel on the short shaft before

with the necessary bottom levers and connections I am enabled to operate a number
of shuttle boxes on both sides of the loom.

page_text: I WILLIAM SMITH of the Sun Iron Works Heywood in the County of Lancaster
Machine Maker, 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 :-
The chief object of my Invention is to obtain a positive strong and steady shuttle
box motion.
In applying my Invention to a loom with several shuttle boxes on one side only
I employ an ordinary pattern chain with holes for actuating the cock heels or pegs
which govern the shuttle box motion. The star wheel and pattern chain barrel are
caused to turn intermittently as usual by a plate wheel mounted on a short shaft
driven from the crank shaft. Now according to my Invention I combine with this
motion a rising and falling motion for the star wheel and barrel and this I effect by
means of a cam secured on the short shaft which cam acts upon a bowl mounted on
a lever one end of which is secured to the axle of the star wheel. When the star
wheel is at the bottom it is turned by the plate wheel and in its upward movement
the chain acts upon the cock heels and their levers. On the lower end of each
pivoted cock heel lever is mounted a spur wheel with a blank space on its periphery
and to an eccentric stud on each of these wheels is connected one end of a long lever
which is connected at the other end to the bottom levers which operate the shuttle
box motion; secured to the loom frame on opposite sides of the above mentioned spur
wheels are two studs each of which carries a spur wheel without teeth on a portion of
its periphery and formed with or secured to a pinion; these two pinions are geared
together by two carrier pinions and the first pinion is driven intermittently by a
segmental wheel cast with or secured to the driving wheel on the short shaft before
mentioned so that whenever the said pinion is driven the two spur wheels on the studs
revolve in opposite directions.
On this segmental wheel is a flange extending partly round it and on the first
pinion is a plate the flange and plate together forming a locking device. for the pinion
after each revolution given to it by the teeth on the segmental wheel.
When the cock heel levers are moved on their fulcrum by the pattern chain and
one of the spur wheels mounted thereon is thereby brought into contact with one of
the spur wheels mounted on the studs the latter which at that moment is receiving
motion from the segmental wheel turns the spur wheel moved into gear with it and
so raises or lowers the long lever connected to the eccentric stud and so actuates the
bottom levers and the shuttle box motion.
When the cock heel levers move both the spur wheels thereon may engage the
same spur wheel or one may engage one spur wheel and the other the opposite spur
wheel to effect the required change in the position of the shuttle boxes which change
is governed by the pattern chain and cock heels.

page_text: By the application of a wider pattern chain and two additional cock heels and
levers with the necessary bottom levers and connections I am enabled to operate a
number of shuttle boxes on both sides of the loom.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a side elevation and Figs. 2 and 3 are end elevations of part of a loom
fitted with my improved shuttle box motion. Fig. 4 is an elevation and Fig. 5 a
plan both on a larger scale than the preceding Figures of part of the gearing.
с
a designates the loom frame and 6 the crank shaft on which is secured a pinion 6¹
which gears into and drives a spur wheel e fixed on a boss or sleeve & mounted loosely
on a stud or short shaft d'; on the boss d are also fixed the following parts :-a
segmental wheel e which has teeth on a part of its periphery only, two cams marked f
and g respectively, and a peg or plate wheel h; i is the star wheel which is fixed on
the end of the ordinary chain barrel ¹ over which passes the pattern chain j, and k k¹
are the pivoted cock heel or peg levers which are operated according to the pattern
on the chain to give the required movement to the shuttle boxes by the connections
hereinafter described.
The star wheel i and chain barrel ¹ are mounted loosely on the axle 2 and receive
the usual intermittent rotary motion from the peg wheel h which revolves with the
boss d and in addition to this rotary motion the star wheel and the chain barrel
according to my Invention receive a rising and falling motion by means of a sliding
bar which is bolted adjustably to the axle and carries a roller which is lifted by
the cam fon the revolving boss d to raise the bar and with it the star wheel i and
chain barrel which fall back by their own weight to their original positions as the
cam leaves the roller ¹. The chain j on the barrel ¹ when raised as above described
acts upon the pivoted cock heel levers k k¹ and moves them on their fulcrum k² the
said levers being subsequently returned to their normal positions by the springs k³.
Near the lower extremity of each cock heel lever k k¹ is mounted a spur wheel m
or m' which has two blank spaces say one equivalent to five teeth on one side and the
other to one tooth on the opposite side and secured to the loom frame a on opposite
sides of these wheels m m¹ are two studs n n' on the stud n is mounted loosely a spur
wheel o which is placed opposite the wheel m and has secured to it a pinion p which
is driven intermittently by the segmental wheel e and is geared by two carrier
pinions p² p³ to a pinion p₁ secured to a spur wheel o¹ mounted loosely on the stud n¹
opposite to the wheel m³ consequently both of the spur wheels o o' each of which has
a blank space on its periphery revolve in opposite directions whenever the segmental
wheel e drives the pinion p. On each spur wheel m m¹ is an eccentric stud to which
is pivoted one of the long levers q which levers q are connected in the ordinary way
to the bottom lever which is fulcrumed at r¹ and connected by a rod s to the plate s¹
which carries the shuttle boxes. On the crank shaft 6 is mounted loosely a lever u
which carries a roller u¹ at one end and at the other end is connected to a spring u¹
to the frame a and to this end of the lever u is pivoted a broken back lever v which
is supported in the position shown Fig. 1 by a plate spring v² secured on the
lever u.
The action of the mechanism above described is as follows:--
When the cam fraises the sliding bar I with the star wheel i and chain barrel ¹ the
pattern chain acting upon the pegs or ends of the cock heel levers k k¹ moves
the said levers or it may be only one of them on their fulcrum k² thereby bringing
the wheels m m¹ into gear both with one wheel o or o¹ or one with the wheel o and the
other with the wheel o' and as the wheels o o' are at this moment revolving since at
this time the pinion p is being driven by the segmental wheel e, it follows that the
wheels m m¹ will be turned on their axes and according to the direction in which they
are turned will either raise or lower the levers q and so actuate the bottom lever r
thereby raising or lowering more or less the rods and plate s¹ and bringing the
required shuttle box into the proper position to receive its shuttle. After the cock
heel levers have been actuated by the pattern chain j as described and the wheels m m¹

page_text: moved into their appointed positions the ends of the cock heel levers k k¹ are both
locked by the broken back lever which is operated by the cam g acting on the roller
and depressing the opposite end of the lever u to that on which the broken back
lever vis pivoted so that the said lever being pressed upward by the plate spring vi
engages the ends of the cock heel levers k k¹ and holds them while the wheels mom¹
are being turned; then as the cam g leaves the roller on the lever u the spring u¹
draws down the lever u and so takes the pressure off the broken back lever v and
allows the springs ³ to draw back the cock heel levers k k¹ into their normal positions
until the said levers are again actuated by the pattern chain j and the cam g again
depresses the lever u as described.
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. A shuttle box motion for looms for weaving in which a rising and falling
motion for the star wheel and pattern chain barrel is combined with the ordinary
intermittent rotary motion of those parts the object of the rising and falling motion
being to cause the pattern chain to act with greater certainty and effect upon the
pegs of the cock heel levers which by suitable connections operate the shuttle boxes.
2. The combination with the cock heel levers, of the broken back lever vand
means for actuating the same for the purpose of locking the cock heel levers while
the bottom levers are being moved to operate the shuttle boxes substantially as herein
set forth.
3. The construction and general arrangement of mechanism constituting my
improved shuttle box motion substantially as herein described and as illustrated by
the accompanying Drawings.
