mso'rrme Davies.-

To all whom it may concern Be it known that I, JOHN WILLIAM Coon, of Eastleigh, Didsbury, in the county of Lancaster, England, haveinvented certain new and useful Improvements in Knotting ficatio p My invention relates to .a device for the Devices, of which the following. is a speci purpose of tying knots in yarns, threads.

twine or the like."

' My invention comprises a novel form of knotting device comparatively light in weight and having the mechanisms for operating. the knotting bill and the drawingofi' device inclosed.

'My invention further comprises an arrangement of parts who by the knot can be tightened and the said lin ofi device driven from the same gearing which drives the knotting bill and an arrangement of parts-whereby the said pull Figure 1 of-the accompanying drawing is 'a. front elevation of my improved knotting device. to Fig. 1 with cover removed. Fig. 3 is a plan view. Fig. 4 is a section view through.

12. Fig. 5 is a side elevation. W

In a preferred construction I employ asuitable metal casting or the like A in'fthe' form of a case or box and having a down-- .wardly projecting extension B which fits against the hand of the operator. Within the case A Im'ounta short transverse'sha ft C or the like carrying a small primary quadrant D the said quadrant 1) having teeth out in its face. .The transverse shaftC extends through the cover A of the case and to the projecting portion C a handle E having a thumb piece E is attached.

The teeth of the quadrant D "mesh with g-the' teeth of a small pinion -F suitably mounted and carryin a secondary quadrant I. or segmental rack, I prefer to employ aknown form of knotting bill I the said knotting bill being carried upon a shortver- 0t pulled-ofi' the knotting bill by means of a rotatable pulling Fig. 2 is a, front elevation similar Specification of Letters I'atent.

tical shaft K suitably supported and rotatable upon a stud, or bearing point L. The knottlng bill I may either comprise a single plece suitably split or cut to form two outer jaws or members or two'separate jaw members between which is disposed a movable jaw member. Formed as part of or attached to the case A is a collar or flange M which collar or flange surrounds the vertical shaft K carrying the knotting bill and is eccentrically disposed in relation to the axis of the said knotting bill shaft. As is known I form the movable jaw member with a cam shaped shank which upon the rotation of the shaft K comes in contact with the inner face of the collar or flange M being consequently actuated by the flange or collar. The knotting bill is sharpened in the usual manner to insure the severance of the threads when desired.

Upon {the knotting bill shaft K a toothed wheel N is mounted which engages with the teeth of the secondary quadrant or rack H.

It will be understood therefore that movement of the rack H in either direction will impart movement to the wheel N and consequently to. the knottingbill shaft K. I employ a loop'tightener and drawing as hook O which is carried on or forms part of a second vertical'shaft or rod P which is parallel with the shaft K. The said drawing off hook projects through the upper portion of the case A iin close proximity to the knotting bill '1. Upon the shaft P, I mount a toothed wheel R having helical or other suitably sd'aped teeth the teeth of the said Wheel R meshin with the teeth of the quadrant or.

rack H. form with the case cover A or 1 attach to the'said cover or to any convenient part of the device a hook or the like S. I attach the case cover A to the case A by means of screws T or other suitable means. The yarns or threads V are placed under the hook of the drawing ofl device 0 beneath the knotter bill I and 'under the stationary hook S. 'The thumb piece E is depressed andthe shortshaft C rotated bringing about the rotation of the knotting bill shaft K. The knotting bill I acts in the manner of known knotting bills to form the knot and sever the ends. The drawing ofi device 0 which rotates with the knottin'g bill I serves to draw theknottight and to draw the knotted threads clearof the knotting bill when the loose ends have been severed. The parts are returned to their orginal positions by means of a spring X which is threaded on and controls the short transverse shaft C.

- I can employ any form of spring arranged in any suitable manner to control the transverse shaft C and the handle E and thumb piece E.

lVhat I claim as my invention and desire to secure by Letters Patent is: v 1. A knot tying device comprising a closed casing having substantially iiat sides and a curved wall connecting the sides, a loop tightener and a knotting bill rotatably F mounted in said case and having their operacasing having substantially flat sides and a curved wall. connecting the sides, a loop tightener and a knotting bill rotatably mounted in said case and having their operative portions projecting from the curved wall of the casing, the axes of rotation being parallel, and gearing within the casing, in-

cluding a primary and a secondary quadrantand r tary toothed members meshin with said quadrants, for effecting the relative operation of the tightener and bill.

3. A knot tying device comprising a closed casing having substantially flat sides and a curved wall connecting the sides, a handle extending rigidly from the casing, a loop tightener and a knotting bill rotatably mounted in said casing and projecting through the wall opposite the handle, the axes of rotation of the tightener and bill being parallel, and gearing Within the cas ing including a primary and a secondary quadrant and rotary toothed members meshing with said quadrants, to effect the rela tive rotation of the tightener and bill.

4. A knot tying device of the character described comprising a closed box or case, a

knotting bill having a shaft mounted in said case, a loop tightener and knot drawing-off device having a shaft mounted in said case, a toothed quadrant or sector, a pinion, a secondary toothed quadrant or sector, a toothed wheel mounted on the knotting bill shaft and engaged with said secondary quadrant or sector, a helical gear secured to the shaft of the loop tightener and also meshing with said secondary quadrant or sector, and a spring controlled thumb piece and connec-.

tions therefrom for actuatingthe said quadrants.

In testimony whereof'l have afiixed my signature, in presence of two Witnesses.
