In the drawings, A represents the frame of the loom, B the vertically arranged
stationary shuttle-race which is formed by means of the bars a and b, having
the slot-opening c between them, an end view of the said bars being shown in
Fig. 4.
The upper portion of the shuttle-race B is provided with the groove b¹,
located within the slot-opening c, the said groove being adapted to receive the
retaining flange of the shuttle C. At suitable distances along the bar b, which
forms the upper portion of the shuttle-race, are placed the upright shafts e e,
(shown in Fig. 3.) provided at their lower ends with the spur-gears e¹, which
serve to drive the shuttle, and at their upper ends with the bevel-gears e², by
means of which the said shafts are driven. In the bearings 62 62 above the shuttle
race B is placed the shaft D, upon which are secured the bevel-gears e³, which
engage with the gears e², the said shaft being driven from the shaft E by means
of the belt F. The shaft E is held in a frame G, which is pivoted upon the bear-
ings and is operated to rise and fall by means of the cam H, secured to the
end of the cam-shaft I and operatively connected with the frame G by means of
the rod f, the upper end f¹ of which is bent outwardly and held in the space f2
between the cars f3 ft of the bracket f³, the said ears serving to form suitable
stops for the upward-and-downward movement of the shaft E, to which the rod f
is loosely secured by means of the cap fo.
Upon the end of the shaft E is secured the friction-roller J, which is adapted
to engage first with the inner side and then with the outer side of the friction-
flange hat the inner side of the wheel K, which wheel is secured to the end of the
driving shaft L, whereby upon the rotation of the wheel K the said roller will
be first driven in one direction and then in the opposite direction by frictional
contact with the flange.
The shuttle C is provided with the rack c¹, which engages with the teeth of the
gears e, by means of which the shuttle is driven back and forth along the
shuttle-race, and the shuttle is also provided with the spring-actuated gripping-
jaws, which operate to seize the end of the weft and draw it through the shed,
the said jaws being provided with the inwardly-projecting pins c³, which are
adapted to engage with the latch-cams c c at the ends of the shuttle-race B,
which cams serve to cause the opening movement of the jaws against the resilient
action of the springs, which serve to close the same upon the weft, the said
latch-cams being pivoted to the point c and limited in their movement by the
stop-pins, attached to the side of the bar b of the shuttle-race.
At the opposite ends of the shuttle-race B, and at the side of the lower bar a
of the same are secured the stationary cutters ii, which upon the downward move-
ment of the knife ¹, held to slide in the guide 2, attached to the upper bar b of
the shuttle-race, serve to sever the proper length of filling from the filling strip
which is being drawn through the trumpet Q, and by means of said trumpet a
comparatively wide flat strip of paper drawn from a roll will be properly crumpled
for presentation to the jaws of the shuttle.

page_text: The knife is actuated in its downward movement by means of the spring ³,
and is raised to its highest elevation by means of the lever i, pivoted at the point 25
to the frame A of the loom, and connected by means of the rod to the lever,
pivoted to the frame at the point 28, and actuated in its upward movement by
means of the inwardly-projecting pin 2, which is secured to the cam H upon
the shaft I at one end of the loom, the corresponding knife at the opposite end
of the loom being actuated by means of the pin 29, attached to the gear R, secured to
the shaft I, sufficient play being allowed between the outer end of the lever
and the knife by means of the opening between the ears at the upper end
of the knife. The knife is retained in its elevated position while the lever i
passes by gravity to its lower position between the ears ji j¹ by means of the
spring-actuated catch 2, which engages with a notch made in the side of
the knife, and is so held until released by the shuttle, as hereinafter described.
To the bracket k, at one end of the upper bar b of the shuttle-race B, is pivoted
the lever k¹, which extends downward to a position in line with the slot-opening c
of the shuttle-race, and to the lever is pivoted the sliding rod ², to the inner
end of which is secured the friction cone, which does not revolve, the said
friction-cone and sliding-rod 2 being supported by the bearing-standards and
forced outward by means of the spring . To the end of the shaft D is secured
the conical friction-cup, adapted to fit the friction-cone and serve to check the
momentum of the shaft D upon the engagement of the forward end of the shuttle
with the lower end of the lever k¹.
To the curved bracket 9, at the opposite end of the shuttle-race, is pivoted the
pendent lever, which also extends downward to a position in line with the slot-
opening of the shuttle-race, and the lever is connected with the lever at
the opposite end of the loom by means of the wire k, so that the outward move-
ment of the lower end of either one of the levers will cause the engagement of
the non-revoluble friction-cone 3 with the rotating conical friction-cup
check the momentum of the shaft D.

The catches are caused to be withdrawn from engagement with the holding-
notch 3 of the knife by the engagement of the shuttle with the beveled lower
end of the engaging piece m, (shown enlarged in Fig. 3,) the said engaging piece
being jointed at its upper end to the bell-crank lever m¹, the upper end of which
lever is connected with the catch by means of the connecting wire m³, and a
weak spring m is employed for holding the engaging piece m in an elevated
position to prevent the engagement of the shuttle therewith upon the return
movement of the said shuttle, the resilience of the spring m which actuates the
catch, being made greater than that of spring m.
The lay-frame M for imparting a forward-and-backward movement to the
fingers employed for beating up the weft is pivoted to the end frames A of
the loom, at the points n n, by means of the pivot-rod, and is caused to vibrate
back and forth by means of the connecting-rods n', which are jointed to the
opposite ends of the frame M and connected with the cranks of the crank-
shaft L of the loom. The upper longitudinal bar n³ of the vibrating frame M
is provided with a slot-opening ', adapted to receive the frame N, which is
arranged to vibrate back and forth with the frame M, and to have an up-and-
down movement thereon and to the forward side of the bar n³ of the frame N are
attached the projecting fingers, which serve to beat up the weft, the said
frame N being provided with the horizontal bar n³, the centrally-arranged bar 18,
provided with the engaging pin, and the downwardly extending end bars 10,
to the lower ends of which are attached the projecting perforated plates o, adapted to
move loosely upon the upwardly-projecting pins oo, which are secured to the
pivot-rods of the frame M, and upon the studs oo' between the plates oo and
the pivot-rod, are placed the spiral springs o², which serve to carry the frame N
and the attached fingers n to their highest elevation. The upper portion of the
frame N is also held for up-and-down movement by means of the links 03 03 03,
which are jointed to the side of the bar 8 and to the inner sides of the end

page_text: bars 10 of the frame N and rigidly secured to the rod o¹, loosely held in th
brackets o o*, attached to the lower side of the upper bar n³ of the frame M, a
shown in Figs. 5 and 8.

To the under side of the breast-beam 0 of the loom is attached the cam
bracket P, provided at one side with the fixed cam o, which is adapted for engage
ment with the pin at the side of the bar 8 of the finger-carrying frame N
The said pin n³, when the fingers are brought forward to beat up the weft, wil
swing into engagement with the end of of the cam o, causing the frame N to be
slightly raised so that when the pin n passes beyond the end of of the cam
the frame N will drop so that on the return movement of the frame M the pin n
of the frame N will pass to the under side of the cam 05, thus causing the frame N
and the fingers nº to be pressed downward against the resilience of the springs o
until the said pin arrives at the end o7 of the cam 05, allowing the fingers to rise
again with the shed back of the weft which has in the meantime been deposited
in the shed by the shuttle, the face of the shuttle-race B being provided with
shallow grooves 08 between the vertical slots o³, made in the shuttle-race to provide
for the shed of the warp-threads, the said shallow grooves being adapted to
receive the points o10 of the fingers 6 and thus prevent the accidental engagement
of the said fingers with the weft when springing upward into the shed at the
face of the shuttle-race. The cam arm P is held against upward movement at
its outer end by means of the rod w, secured to the floor.
The shuttle C is shown in Fig. 1 as in the act of dropping the weft, the rear
gripping jaw 2 having been just raised to release the weft by means of the latch-
cam c, the forward gripping-jaw c² being held in its opened position by means
of the fixed guide e, which extends outward from the pivoting-point c of the
latch-cam c, and upon the continued forward movement of the shuttle the in-
wardly-projecting pin of the forward gripping-jaw will pass off of the fixed
guide and will then seize the previously-cut end of the weft. The acquired
momentum of the shuttle and its actuating mechanism, if sufficient to carry the
shuttle to contact with the lower end of the lever k¹, will actuate the friction-
cone into engagement with the friction cup to check the momentum of the
shuttle-actuating mechanism.
When the shuttle in its passage through the shed arrives at the beveled lower
end of the engaging piece m, (shown in the section, Fig. 3,) it causes the upward
movement of the said engaging piece and the corresponding movement of the
bell-crank lever m¹, which is connected by means of the wire m³ with the catch ²,
which holds the knife ¹ in its elevated position, causing the withdrawal of the
said catch from its holding-notch 13, thus releasing the knife to cut off the weft,
the catch being held in an outward position against the vertical side of the
knife when the knife is at its lower position. The connecting-wire m³ will thus
be slackened by the outward movement of the catch 2 from its notch, so that
the spring m, which is weaker than the spring m³, will serve to hold the engaging
piece m in its elevated position after the shuttle has passed beyond the said
engaging piece, thus preventing the engagement of the shuttle therewith upon
its return movement, and the said engaging piece m will be held in its elevated
position until the knife is again raised either by the action of the pin 19 of the
cam H or the pin of the gear R, as the case may be. The resulting passage
of the catch into its notch will cause the tightening of the wire m³ and the
downward movement of the engaging piece m preparatory to the succeeding
engagement of the shuttle.
The reverse travelling movement of the shuttle through the shed is effected
by the engagement of the friction-roller J first with one side and then with the
other of the friction-flange h of the wheel K, as the said wheel is being rotated,
but other means for producing the required reverse movement may be employed.
The weft, which may consist of a comparatively wide strip of paper, is to be
folded or crumpled from its flat outspread condition by being drawn through
the trumpet Q and cut off at the length required while being drawn into the shed,

page_text: thus producing a fabric having a crumpled-paper filling which is adapted for
a carpet-lining, but when a twisted weft is employed the trumpet is not required,
suitable means being provided for supporting the filling in position for the
engagement of the shuttle.
By arranging the stationary shuttle-race in a vertical instead of a horizontal
position and providing the shuttle-race with the transverse openings for the shed
of the warp-threads I am enabled to employ the upper side of the shuttle-race
for the attachment of the special shuttle-driving means without interfering with
the warp-threads.
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:
1. The combination of the vertical shuttle-race, provided with the transverse
openings for the shed of the warp-threads, and with the grooves to receive the
fingers for beating up the weft, the shuttle, and means for operating the same,
with the projecting fingers for beating up the weft, and means for actuating the
said fingers downward from the warp-threads, backward to the grooves at the
vertical face of the shuttle-race, thence upward in said grooves and between
the warp-threads at the rear of the weft, and forward between the warp-threads,
to beat up the weft, substantially as described.
2. The combination of the vertical shuttle-race, and the shuttle provided with
the rack, with the gears engaging with the rack, means for alternately reversing
the movement of the gears to cause the back-and-forth movement of the shuttle
through the shed, and the rotary friction device, actuated into engagement by
the shuttle, and operating to check the momentum of the shuttle-driving-means,
substantially as described.
3. The combination of the vertical shuttle-race, the shuttle and means for
causing the back-and-forth movement of the shuttle through the shed, with the
stationary knife, and means adapted to be engaged by the shuttle, to cause
the knife to sever the weft, substantially as described.
4. The combination of the vertical shuttle-race, and the shuttle provided with
the spring-actuated gripping-jaws, the latch-cams for opening the jaws of the
shuttle, the spring-actuated knife for cutting off the weft, means for raising the
knife, the catch for holding the knife in its raised position, and means adapted
to be engaged by the shuttle, for withdrawing the catch, substantially as
described.
