page_text: I, CHARLES BEDFORD, of Wood View Terrace, Carlinghow, Batley, in the County
of York, Mechanic, do hereby declare the nature of this invention to be as follows:-
My invention consists in the employment of a new construction and. arrangement
of mechanism for positively forcing the shuttle boxes up and down according as they
are selected by the Jacquard mechanism.
In carrying out my invention I employ a number of horizontal booked bars, the
number being determined by the number of shuttle boxes. These bars are caused
to oscillate backwards and forwards by reciprocating crossbars, when they are selected
or put into position by any form of pegging mechanism. The horizontal hooked bars
are provided with a rack at one end gearing with pinion wheels to which eccentrics
are attached, so that on the horizontal bars being reciprocated backwards and
forwards the eccentrics are caused to revolve. When a movement to the extent of
7 boxes is required I use three series of hooked bars, pinions, eccentrics, and bell
crank or other levers. One series moves to the extent of one box, another to the
extent of two boxes, and a third to the extent of four boxes; two series moving
together moves the boxes to the extent of three, five, or six boxes according to
selection by pegging mechanism. All the series moving together in one direction
moves to the extent of seven boxes. One of the eccentrics is connected to one arm
of a bell-crank or other lever, the other arm of such bell crank lever being connected
to a vertical rod, the lower end of which rod is connected to a long lever at a point
near to one end, which carries the shuttle boxes at the other end, therefore, when the
shuttle boxes are required to be operated to the extent of one box, the eccentric
oscillates its bell crank lever, and, consequently, it rocks the lever carrying the
shuttle boxes, upon a stud or pin placed at or near the centre of such box lever,
carrying a pinion wheel. On each side of such wheel is a rod with rack at one end,
the other end being connected to arms of the bell crank levers. When, however,
the boxes have to be operated to the extent of two or more boxes, one end of the

page_text: bell crank levers are connected to vertical racks in gear with the pinion on the
fulcrum of the bottom rocking lever carrying the boxes, antifriction bowls or rollers
being employed to keep the vertical racks in gear with the said pinion, so that when
the eccentrics are operated the bell crank levers and racks are also operated in such
a manner as to move the pinion carried by the bottom lever up or down, causing
such lever to oscillate for the purpose of moving the boxes the required distance.
By this means the boxes are pushed up and down the required distance with very
little vibration. By an arrangement of spiral springs the lever carrying the boxes
can be so balanced as to keep the full weight of the several parts from resting upon
their fulcrums, by which means the wear and tear of the pins and studs are reduced,
and the movements of the parts are more easily effected.

I CHARLES BEDFORD, of Wood View Terrace, Carlinghow, Batley, in the County
of York, Mechanic, 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:-
1
My invention consists in the employment of; a. new. construction, and arrangement
of; mechanism, for.positively, forcing the shuttle boxes up, and down according as they
are selected by the Jacquard or pegging mechanism...
Such being the nature. and object of my invention,: I will now proceed to describe
the same more fully, and for that purpose make, reference to the accompanying sheets
of drawings illustrative. thereof, wherein Fig. 1 is, elevation, of such, parts of a loom
as is necessary to illustrate my improvements.. A represents the framework of a
loom, B the crank shaft, C the rising and falling shuttle boxes.supported on the top
of the vertical rod D, which by link E. are, carried on..the end of lever F, the other
end of such lever being connected by rod G to lever H, working upon a fulcrum I,
the other end of such lever H being attached to; vertical connecting rod J secured
eccentrically at k. on the face of, the pinion wheel K., the teeth, of which gear with a
rack L forming part of the bracket, M, suitably supported and capable of sliding back-
wards and forwards when required to give rotary motion to the pinion K for purposes
and in manner hereinafter, described.. To the toothed, bracket M, shewn in details
Fig. 3 and plan Fig. 4, are attached two horizontal hooked bars N and O, which bars,
together with the rack, are made to move backwards and forward's horizontally by
reciprocating crossbars P1, P2, and P³. The hooked bars N and O which operate the
shuttle boxes through the intervention of the various levers and rods already
mentioned are selected by ordinary Jacquard or pegging mechanism as shewn at R,
where a represents, the peg.lags for lifting the lever arm b, which on being raised lifts
one of the needles c, and with it one of the booked levers N or. O, whereby the hooks d
formed, on the said, bars, are placed into position for being caught hold of by the
reciprocating.crossbars P1, P and P. I would also observe that the lever F has no
stationary fulcrum, but is suspended by the pinion Tand joint Y. In order to prevent
the centre -E moving too far: either,backward,or, forward, Luse a slotted bracket A³,
secured to the framework, of the,,machine, in the, slot of which, bracket is placed a
runner A² attached by stud to the lever F, so that as the lever., F rises,, the bowl A³
will follow. up the slot and, keep centre, E¹ in its proper relative position, during, which
movements the lever F (having, no, fixed, fulcrum) will have. been pushed, laterally
towards the right hand, as seen in dotted line Fig. 5. In order to keep, the racks V
and S in gear with the pinion. T I, employ.the-two antifriction bowls W and X.
I will now, proceed, to describe the action, of, the, several parts. The drawing, as
represented shews, the shuttle boxes to be at the bottom, but if the boxes are required
to be raised one lift, the pegging mechanism, operates, needles.c, in such a manner

page_text: according to the present position of the several bars and hooks, that the bottom hooked
bar O would be raised. The upper one could not be raised in consequence of bar P¹
resting on the top of the hooked bar N, but in that case, the spiral spring around the
needle c would yield and allow for it. After the lower bar O has been raised as shewn
in dotted lines, crossbar P2 will be engaged with the hook on the upper side of
hooked bar O, therefore when bar P² advances towards the pinion K the rack L will
be carried with them in such manner as to oscillate pinion K, in doing which the
rod J would be raised as shewn in dotted lines, lifting lever H, lowering rod G, and
with it the lever F upon the stud of pinion T, which forms a fulcrum, consequently
the downward movement of centre Y will give the other end of the lever F a corre-
sponding upward motion, whereby the boxes will have been raised to the extent of
one box, as indicated by dotted lines. When the boxes have to be raised two lifts, the
hooked bars N and O are selected in a like manner to that just described, but in this
case, another rod like J will lift lever R, bringing with it the rack S, pinion T, and
lever F, and in this case the said lever F will oscillate upon centre Y as a fulcrum,
giving the boxes a motion to the extent of two lifts, in addition to the one already
lifted, thus a rise to the extent of three boxes has been made, but if only two boxes
are required to be lifted, then the lever R and its relative parts can be operated without
lever E, in which case only two boxes are lifted, as shewn in dotted lines, Fig. 5, on
sheet 2; and when the boxes are required to be lifted to the extent of three boxes,
only another rod J lifts lever U and with it racked bar V together with the lever F,
which again makes Y its fulcrum, thereby lifting the boxes to the extent of three,
alone, or in addition to those already raised, by which means, that is, by lifting lever U,
the shuttle boxes can be raised three boxes, or four, five, or six boxes. It must be
understood that there are, as shewn in plan view Fig. 2, three sets of pinions and
racks and hooked bars. It will be seen that I have employed three crossbars P¹ P,
and P3, and it will also be seen that there is one notch on the top of each hooked bar
and one notch underneath each hooked bar, consequently one or other of the said bars
is always in a position to be acted upon by the crossbars Pi P2 and P3 whether the
said crossbars are moving backwards or forwards, in which case for one traverse of
crossbars I ensure that the hooked bars are operated according to selection, and in
every reciprocatory movement of the crossbars, the hooked bars are moved with them.
In order to further explain the function of the crossbars P1 P2 and P3 I would explain
that according to the drawing, two of the said bars are near the pinion K and one
near the shuttle boxes, but whenever the one which is now near the shuttle boxes
advances to the pinion K, the other two advance in the same proportion nearer the
shuttle boxes and vice versa, and I would remark that the snecks on the upper side of
the hooked bars are employed for raising the boxes, and those on the underside for
lowering the boxes, or vice versa. Crossbars P1 and P³ are attached to one and the
same sliding block, but crossbar P2 is attached to another sliding block, the arrange-
ment being such that crossbars P₁ and P³ move together and P2 in the opposite
direction.
So far the apparatus has only been described as regards the raising of the shuttle
boxes, but my improvements are equally good for lowering the shuttle boxes, and I
will now describe the action of the apparatus when lowering the boxes; therefore
when the hooked levers N and O are in the positions shewn in dotted lines in Fig. 1,
and the several crossbars P1 P2 and P3 also in the positions shewn in dotted lines of
Fig. 1. On reference to the drawing, it will be noticed that the dotted levers N and O
are elevated or pegged up, but when a change is required and a peg à is absent, the
upper bar N would lower and engage with the dotted cross bar P2, which said cross
bar now becomes both a moving bar and a retaining bar for preventing the weight of
the descending shuttle boxes from forcing both hooked bars N and O. forward quicker
than the crossbar P2 travels.
The function of the three crossbars is two-fold; in the first place they are employed
to operate the hooked bars, and in the second place they are employed as holding or
retaining the said bars to prevent the too sudden dropping of the boxes after the
stud has passed the centre of the pinion K, because if the crossbar P² were not there

page_text: in the position shewn in dotted lines immediately the centre k gets past the centre of
the pinion K, the weight of the shuttle boxes would propel the hooked bars quickly
forward, in which case the said boxes would drop too quickly and rebound, but in
consequence of bar P2, being within the notch on the side of the lower lever O, the
weight of the shuttle boxes cannot force hooked bars N and O quicker than the bar P²
will permit them, consequently there is a steady downward movement of the boxes.
Although I have shewn and described my improved apparatus as raising and
lowering shuttle boxes from one lift to six lifts, I would remark that the apparatus
can be made to operate several more boxes, and this I would do by removing con-
necting rod G and employing at that end of lever F another pinion T and racked
bars S and V together with another set of hooked bars N. and O, rack L, rods J and
one or more levers like H coupled and connected in the same manner as are levers R
and U.
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 :-
.
Firstly. In looms, for raising and lowering the shuttle boxes, the combination of
lever F, pinion T, levers H, R, and U, together with racks V and S, all arranged.
substantially as shewn and described.
Secondly. The employment of a series of. hooked bars such as N and O, in
combination with a corresponding series of racks L, pinions K, vertical rods J, and
levers H, for operating the shuttle boxes of looms in manner substantially as set
forth.
Thirdly. The combination of the several parts enumerated in claim 1 in combination
with the several parts enumerated in claim 2, connected and operated in manner
substantially as described.
Fourthly. The employment of two hooked bars N and O, in combination with three
reciprocatory crossbars P1 P2, and P³, employed for the purpose of operating the said
hooked bars, and also for the purpose of preventing the weight of the shuttle boxes
descending more rapidly than one or more of the bars P² P2, P³, will permit.
