Fig. 7 represents, the six cards used where six shuttles are employed.
Figs. 8 and 9 are two views showing the method of applying my invention to
drop boxes.
In the first place I will describe my invention as applied to an ordinary circular
shuttle box and which is illustrated on Sheet 1 of the drawings.
As in my former invention I retain the usual card barrel a operated by the
cam a¹ on the tappet shaft 2 through the double lever a³ pivotted at a to the side
of the frame A of the loom.
The card barrel is perforated as shown in Fig. 3.
The lever as it will be understood is vibrated in the direction of the arrow by
means of the cam a¹ and returned by the tension of the spring b. The pivotted
catch c operates as usual at every vibration of the lever ³ to revolve the square
card barrel a a quarter of a revolution and present a fresh card. The cards are
operated against two notched plates d d which are identical with those described
and claimed in the specification of my said former invention.
The notched plates dd are provided with six notches to correspond with the
number of shuttles employed although less or more than six could be used accord-
ing to the number of shuttles it is desired to actuate.
The notched plates dd are mounted to slide in ways formed in a bracket
secured to the loom framing and are connected to a cross head e secured to the
vertical shaft e¹ mounted in bearings e carried from the frame A.

page_text: This arrangement is practically identical with that shown in the specification
of my said former patent and it is from this point that my improvements relate.
The cross head e is or may be provided with a spring detente engaging with
teeth or notches formed in a fixed bar the notches corresponding in number to
the number of shuttles employed. The cross head is thus steadily maintained in
position until the next movement of the notched plates d.
The lower end of the shaft e¹, which is rocked in its bearings by means of the
cards acting upon the notched plates d d and cross head e as described in my
former specification, carries a finger or lever f provided with a pin f¹. The

engages with a slot f2 formed in a plate f3 secured to a bar g.
Connected to the sliding bar g is a double fork the arms of which embrace the
bosses of two bowls or discs ; which are slidably mounted upon pins 1 secured to
the cradle h. Upon the tappet shaft a² is keyed a spur pinion k meshing with a
pinion secured to a short shaft 7, and through a carrier pinion 12, with a pinion 14
mounted upon a short shaft 14. The shafts and 14 are carried in bearings formed
in the frame of the loom and in brackets m m secured to the framing and are
revolved by the gearing in the direction of the arrows. Upon the revolving
shafts I secure oppositely arranged stepped cams n n shown in Fig. 1 and in
plan view Fig. 4. The cradle h is connected to a rod o adjustable in length at o¹,
formed at the lower end with a joint o² to render it flexible. The lower end of
the rod o is secured to the slotted end of a lever p pivotted at pl to a bracket pa
upon the sley sword shaft 73. The pivotted lever carries a quadrant 7 to the
top of which is secured a chain the lower end of which is connected to the bottom
of a rod to the upper end of which is secured a rack r¹. About midway in the
length of the rod is secured the end of another chain 2 the other end of which
is secured to the lower end of the quadrant. Upon the axis of the circular
shuttle box B I mount a pinion s. The rack is held in a slide s carried on the
end of a double lever s pivotted at $3 to the vibrating arm t'and'a spring s tends
constantly to turn the slide s upon its pivot and thus maintain the rack
engagement with the pinion s. It will be understood that as the 'circular shuttle
box B is vibrated with the sley &c. the rack r¹ and rod r partake of the same
motion the chains forming a flexible support for the rod and rack. Instead of
suspending the rod r in chains as described I may mount it to slide in bearings
carried by the vibrating arm t connected' to the shuttle box and mounted on the
sley sword shaft 23, and provide the lower end of the rod with rack teet
teeth engaging
with teeth upon the quadrant pt.

in
The function of the pivotted lever and quadrant 24 is to raise and lower the
rod r so as to revolve the pinion s mounted upon the axis of the circular 'shuttle
box as will be hereafter explained. A spring detent carried by a bracket
engages with notches formed in a disc 2 upon the axs of the shuttle box so as to
maintain the shuttle box in its required position.

.
In case the shuttle box should become jambed the slide will yield against the
action of the spring st and the teeth of the rack will slip over the teeth of the
pinions and thus prevent a breakdown.
I will now describe the action of the mechanism.
As. in my former invention each card indicates and directly actuates its own
shuttle box and that alone, that is to say card 1 brings round box 1, card 3'box 3
and so on.
Fig. 7 on Sheet 2 of the drawings shows the six cards used for a six
shuttle box. The cards, which are the same as in my former patent, are arranged
in their order to actuate shuttle boxes 1 to 6 Card No. 1 will admit one of the
plates until the sixth notch bears against the card the first notch of the other
plate encountering a blank on the card. Card No. 2 admits five notches and one
Card No. 3 admits four notches and so on until the sixth card is 'reached which
card is a reverse, of the first. The perforations on the cards engage with conical
snugs or projections on the card barrel which feeds forward the chain of cards

page_text: in the usual way. Referring to the plan.view Fig. 6 No. 6 card has been pre-
sented and the rock shaft e¹ turned in its bearings. The lever f actuates the slide
bar 9 carrying with it the double fork i which thus slides the discs ; until they
are disposed immediately above the cam discs 6 and 1 reading from right to left.
This movement takes place when the cam discs are rotating in their lowered
position as shown in Fig. 1 and during the outward movement of the sley.
As the cam discs n n are raised the largest cam No. 6 engages with one of the
discs and elevates one end of the cradle h, the other discs resting upon the
smallest cam 1 which acts as a stop to limit the rocking movement of the cradle.
The elevated end of the cradle h in its upward movement has raised the connecting
rod o' which rocks the pivotted lever which. by means of the attached chains,
pulls down the rack rod r revolving the shuttle box to bring No. 6 shuttle into
action. Should the next card be also No. 6 no alteration takes place in the
position of the cradle h and the narts remain as shown in the drawings. When
a change occurs in a card, say in No. 3 being presented by the card barrel, the rock
shaft eis rotated actuating the sliding bar and the fork directs the discs jover
cam marked 3 at the right hand of Fig. 4 and above cam 4 at left hand.

Cam No. 4 will thus raise the lowered end of the cradle & lowering the connect-
ing rod o sufficiently to rotate the shuttle box to bring No. 3 shuttle into action.
It will thus be readily seen that the perforated cards operate the rock shaft e
so as to select any one shuttle out of the series and this may be done consecutively
from 1 to 6 and vice versa or one or more shuttles may be skipped over, that is to
say the shuttle box may be revolved one sixth of a revolution, five sixths of a
revolution, or less, so that a change can be at once effected to any desired box.
Twill be understood that the stepped cams are oppositely arranged to effect
the desired rocking or oscillation of the cradle h. As shown in Fi. 1 the cradle h
has been rocked into the position indicated by means of right hand cam No. 6.
If it be desired to change to shuttle Nos. 1 and the discs are traversed as
described, left hand cam No. 6 will oscillate the cradle h to effect the change.
On sheet 2 I show my invention applied to the drop boxes of looms Fig S
being an end elevation and Fig. 9 a side elevation of so much of the mechanism
as is necessary for the comprehension of the arrangement.
The mechanism up to and including the cradle h and the method of actuating
the same is exactly as already described and need not be repeated.
To the slotted end of the cradle h is connected a pivotted rod whinged to a
rack sliding within a guide ² secured to the frame of the loom. The rack w¹
gears with a pinion 103 secured to a boss a mounted to revolve unon a stud a*.
The boss carries another pinion al and a notched disc with which engages
a spring bolt a³. As the cradle h is oscillated by means of the stepped cams as
described the rack w¹ communicates motion through the pinion w³ and pinion r¹
to the rack y secured to the shuttle box rod y¹ so as to bring the required box into
action.
The spring bolt retains the parts in position until the next change. To
counter-balance the shuttle boxes the lower end of the rack y is secured to a
strap passing over a bowl y³ the other end of the strap being secured to a spring z.
A relieving motion is also applied consisting of a spindle 2¹ carrying a forked head
embracing the rack y and thrusting the rack into engagement with the pinion by
means of a spring 2.
The forked head of the spindle 2¹ can be removed from the rack y by means
of a handle a swell thereon thrusting away the spindle. This relieving motion
and the method just described of counterbalancing the weight of the shuttle boxes
are however not novel and form no part of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-"
