JAMES RANDOLPH GREENWOOD BRIERGLIFFE, OF MOSES GATE, BOLTON, ENGLAND.
YARN-TESTING MACHINE.
To all whom it may concern:
Be it known that I, JAirns RANDOLPH GREENWOOD BRIERCLIFFE, a subject of the King of Great Britain, and resident of Lime Trees, Moses Gate, Bolton, in the county of Lancaster, England, have invented certain and useful Improvements in Yarn-Testing Machines, of which the fol lowing description, together with the ac companying sheets of drawings, is a specification.
My invention relates to a new or improved machine for automatically testing the strength and stretch of single strands or threads of fibrous substances, such as cotton, worsted, linen, jute, and the like, which also includes partly prepared yarns such as those known in the condition of rovings. To attain this object I make use of the devices illustrated by the accompanying sheets of drawings, wherein Figure 1 is a front elevation of the apparatus produced in accordance with my invention and shows it in position as when testing a thread of yarn. Fig. 2 is an end elevation of same as seen in the direction indicated by the arrow at. Fig. 3 is a plan or view of the apparatus shown by Fig. 1, seen from above. Fig. 4 is a similar view to Fig. 1 but illustrates the relative positions of the several parts when the thread has broken under the test to which it has been put. Figs. 5, 6 and 7 are front and end elevations and plan respectively of modifications hereinafter described.
In carrying my invention into effect I make use of a lever Z of the first order the same being pivoted ati, and having its arms 3 and 4 extending to the left and right of said pivotal center 2. The bearings 0 upon which said lever is pivoted are fixed upon the base piece (Z, to which all the other fixings are secured as hereinafter explained, and said base piece cl has loops or rings 5 and 6 secured to it so that it may be suspended or hung upon the wall, ceiling or the like, where it may be held at any desired height from the floor to suit the convenience of the user.
On the arm 4 of the lever Z) a runner f is mounted so that it may revolve upon, or roll over the upper edge of said arm 4 and from this runner f the weight g is supported by a connecting rod 9 so that as said runner descends or travels over the arm 4 the weight g by gravity depresses it for Specification of Letters Patent.
Application filed November 6, 1909.

Serial No. 526,647.
the purposes hereinafter explained. The
As the weight g descends or as the runner f travels over the arm 4 by the action of gravity it carries with it the end of the cord 29 which encircles a grooved pulley or drum 79 mounted upon bearings Q secured to the base piece cl. This drum 29 has mounted upon its axle a coiled spring 8 as well as the gearing wheel 79 this latter being connected by a train of wheels p to the momentum governor r of well known construction. Upon the same base piece 0? a spring clip 25 is mounted within the grip of which may be placed the cop of yarn which has to be tested, or if it is yarn from the roving, then the same may be mounted as shown in broken lines at 2& so that said yarn may be carried therefrom to the part h where it is secured, and forward to the part it as hereinbefore described.
In operation. the runner f and its weight g normlally occupy the position indicated in Fig. 1, being held in that position by the portion of lever arm 4, the speed of rotation of drum p and consequently the speed. of travel of said runner, being regulated by the governor a". As the runner progresses the lever arm 4 is depressed and this movement continues until the arm 3 of lever b has traversed a distance suliicient to stretch thread to the breaking point, whereupon the lever arm. 4 will immediately come in contact with the sliding piece a, and through the rod of, lever arms a and a, and rod a, cause the lever a to move the catch piece Q2 so asto again engage with its wheel p thus arresting the further movements of the train 72 and consequently of the runner f and its weight g. The strain put upon the thread Z: is such as is indicated by the position that the pointer on the connecting rod shows on the scale a which is carried by the arm L, and as will be understood this scale a is regulated in accordance with the actual weight of the weight g, that is to say, if the weight g is comparatively light then the scale a may be graduated to represent ounces, whereas if it is comparatively heavy then the scale a may be graduated to represent pounds, and the indicator at the end of the arm 3 may also be watched or noted as to the graduation that it was pointing at on the scale a at the time that the thread 7; was broken, and this will show the amount of stretch that was put upon said thread 76 before it was broken.
Provided it is not convenient to watch the pointer 3 on the end of the arm 3, then I may have a glass or transparent tube a in which I place a transparent liquid as water, glycerin or the like, in which a small weight of substantially piston form may be allowed to descend, said weight being connected with its red to the cord Q1 passed over the pulley v to be connected to the end of the arm 3 so that on the thread is being broken the weight would indicate its position on the scale formed on the surface of the tube 1) and said weight will. be held in the position it occupied on the breaking of the thread by the lever 10 (pivoted at 10 being moved by the part 71,2 on the lever b so that the cord e is clamped against the part Q03.
.To re-adjustthe several parts to their positions as shown in Fig. 1 the user has to rotate the drum 79 only, by the winged handle to.
Suitable stop pieces to, Q07 are mounted on the casing g and the pulley respectively to arrest the motion of the said pulley 79 in either direction so as to prevent over winding or overrunning of the motor.
Should it be found that the testing of extremely delicate yarns is interfered with by the cord 7) being out of alinement with the center 2 of the lever b I mount the drum 79 in the position as shown by Figs. 5, 6 and 7, then said cord 79 is always in alinement with the center 2 and the axis of the arm 4, thus the pull on the cord will always be against said center 2 and parallel with the axis of the arm 4:. To effect this I mount upon the axle pin 6 a guide pulley Z) which will move with said axle pin 1) and may freely revolve around its own center and in the plane of the center of said spindle If. The cord p is connected to the cross-piece 9 of the connecting rod 9 said cross-piece moving in the slot 6 in the lever Z).
Instead of arranging the pointer on the connecting rod I may arrange such pointer to be carried by a pulley mounted on a spindle in bearings loosely pivoted on the pin 7 which supports the runner 7 (see dotted lines Fig. 5) thus the position of said pointer g relatively with the scale a is not affected by any oscillatory movements of the connecting rod Such being the nature and object of my said invention. what I claim is:
