page_text: Date of Application, 15th Dec., 1891-Accepted, 13th Feb., 1892
In the drawings, 1, is the work table rigidly mounted in suitable supports with
the side piece 2.
A frame 3, extends over the front end of this table.
Frame 4,
extends over the rear end of the table.
The main drive shaft 5, extends beneath the table and is driven by gearing 6
and 7, and has cams 8, and 9.
A rock shaft 10 is in the frame 4, above the table having connected arms 11, at
their lower ends having the pivoted feeder 12, so that its lower free edge provided
with the feeding projections 13, can be held yieldingly pressed down upon the
upper surface of the table by spring 14, secured to plate 12, and bracket 15, so that
when the shaft 10, is rocked rearward fingers 13, will move over the surface of the
table towards its rear edge, the spring 14, throwing projections 13, into the fabric,.
and when rocked forward the fingers will slide over the fabric.
The cam 8 operates on the swinging lever 16, having a lateral stud held up
against said. cam. Connections 17, secure lever 16, to crank arm 18, of shaft 19,
carried by frame 4. The shaft 10 has a. crank arm 20. Link 21 connects arm 20
and crank 18, so that cam 8 depresses lever 16, and rocks the feed shaft by con-
nections 17, and arms 18, and 20, and throws the feeding device back. When
lever 16, swings up shaft 19 is oppositely rocked and turned to its normal position
by spring 22, secured to arm 23, thereby feeding the fabric.
24 is a stationary blade at the rear edge of the table flush with the upper face
thereof. Swinging blade 25, co-acts with blade 24, and is pivoted at one end
thereof to sever the fabric fed between the blades. The movable blade is swung
by toggle links 26, and 27, respectively pivoted to the movable blade and to upper
end of frame 4. Pin 28, projecting from inclined sliding plate 29, pivots the toggle
links together. Plate 29, slides in the frame 4, and has its sliding movement
limited by suitable means. Link 30 connects pin 28, to one arm of bell crank lever 31,
and rod 32 connects the other arm of lever 31, to the free end of the lever 33,
having a lateral stud bearing on the under edge of cam 9. A. spring 34 yieldingly
holds the blade and parts in their raised positions, see Fig. 4.
When the fabric has been fed forward the cam 9, depresses the lever 33 operating
the bell crank lever 31, to draw down the plate 29, and expand the toggle links and
throw down the movable blade and shear off the fabric. Plate 29, has inclined
edge 35, which engages the upper edge of the slot, in which the plate works to force
down the said plate and the cutting blade at the end of the stroke completely to.
engage the stationary blade throughout its entire length.
Mechanism is provided to hold the fabric while being cut and to regulate the
lengths cut off, consisting of the vertically adjustable lower bar 36, located in a

page_text: slot in the rear edge of the table parallel with the stationary knife and having
adjusting screws 37 (Figs. 7 & 8) and a movable gauging bar 37¹ secured to cross
bar 38, carried by arms 39, above the table having cross bar 40, at their rear ends
in front of frame 3. The horizontal stationary rod 40¹, secured to frame 3, extends
through slots 402, in arms 39, permitting vertical swing of the presser gauge bar.
A spring 41 (Figs. 3 & 9) connected at one end to a fixed pin 413, holds the movable
pressure bar towards the cutting blade, and screws 42, regulate the distance
between the movable pressure bar and the cutting blade. A rod 41 extends up
from pressure bar frame through the bracket 15, with an arm 43', in a vertical
slot 432, in said bracket. A spring 44, presses said rod and the pressure bar down
on the fabric. Pressure bar 371, is raised by bell crank lever 45, having a cam
end 45, under end 43', of the rod 41'.
'
Rod 46, connects lever 45 to one arm of bell crank lever 47, having its other arm
connected to the movable lever 48 controlled by cam 8. When said lever 48, is
raised the pressure bar will be raised and when the fabric has been fed forward
said cam allows the lever 48, to drop, and the spring 44, forces the pressure bar
down on the cloth while the cutter blade severs the same.
A clamp is provided to grasp the fabric and draw it out between the knives and
hold it taut while being cut off, composed of rigid jaw 47', and under movable
jaw 481 carried by loose arms 49, from the shaft 19. The jaw 48' consists of rear-
wardly extended sides connected by a cross bar 51, and pivoted to the cross bar
carrying the rigid jaw so that the clamp is normally open. The arm 52, extending
down from the shaft 19, is composed of two loose parallel plates secured a distance
apart with the short arm 53, between them and rigid on the shaft and connected to
operate the loose arm 52, by the curved rod 54, rigid with said two plates, extending
loosely through an aperture in arm 53, and having a coil spring 55, between the
rear side of arm 53, and a stop on rod 54. The clamp is drawn back with arm 53,
against tension of spring 501 by the curved arm 57, rigid with the clamp and having
the end extending around the rear edge of arm 52.
A movable trip 56 is in the lower end of arm 52 to lock the clamp closed, and
is controlled by the connection 58, so when the clamp moves back its full stroke
connection 58 holds the trip and releases bar 51 from the lower beveled shouldered
end 59, allowing the lower clamp jaw to drop. When the shaft 19, moves oppositely
the fabric is fed forward, the gauge bar and the cutter are raised and the open
clamp swings in, and the fabric is fed between its open jaws; as the clasp con-
trolling arm swings its beveled end 60, strikes the upper side of the rear cross
bar 51, forcing up said jaw and tightly clamping the fabric. Said cross bar also
engages the shoulder 59, of trip 56, (connection 58, allowing the trigger to project
below the end of the arm 52, when in this position) and operates the trip to hold
the clasp locked. The shaft 19, then rocks oppositely and the clasp draws out the
fabric until the welt therein engages the gauge bar, and holds the same while being
cut, the trip then allows the clasp to open and drop the piece cut off.
Arm 53, has a fixed stroke, but the length of fabric to be cut off varies; the
spring connection before described between the clasp controlling arm 52, and the
shaft 19, is provided so that the short arm 53, rigid on the shaft 19, can move out
the same distance every stroke, even if a welt in the fabric engaging pressure bar
prevents the clasp and loose portion of arm 52, moving out the full length stroke
with arm 53; the arm 53 moving out its full stroke by compressing spring 55.
The stroke of the feeding mechanism can be varied by means of the series of
apertures in arm 18, and removable crank pin.
The drive shaft, or in fact the various mechanisms can be actuated in any desired
manner other than shewn. I do not limit myself to the exact construction shewn.
The ribs, wristbands, etc., for knitted goods, such as hosiery, underwear, are
ordinarily formed in strips with the transverse welts therein which form the outer
edges or heads of the ends of the garment. This machine automatically cuts these
strips so that each piece will have a welt at one edge thereof.
This machine can be employed for cutting other material than here described.
