RING- AND FLIER DOUBLING-FRAME.
Specification of Letters Patent.
Patented July 19, 1910.
Application filed November 18 1909. Serial No. 528,714.
To all whom it may concern:
Be it known that we, ARTHUR BENT and JoI-IN HERBERT WHITELEY, subjects of Great Britain, residing at Stockport, in the county of Chester, England, Kingdom of Great Britain, have invented new and useful Improvements in and Connected with Ring and Flier Doubling-Frames, of which the following is a specification.
Our invention relates to improvements in and connected with ring and flier doubling frames and has for its object the construction of an improved fourfold and roller lap preventer which can be readily attached to any type of frame, and is simple and reliable in action.
Our improved four-fold and roller lap preventer is as usually controlled by an arm resting upon the thread and consists chiefly of a trap comprising a fixed surface and a screw-threaded spindle employed at the back of the roller in the path of the thread and having a tumbling weight and an arm fulcrumed to the latter, a portion of which arm normally rests upon the thread and when the thread breaks falls upon the bottom roller and being moved back thereby causes the tumbling weight to fall and turn the said screw-threaded spindle and the latter to press its end against the said surface, and thereby nip the thread at the back of the roller.
We attain this object by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a front view. Figs. 2, 3 and 4 are sectional end views of a portion of a ring doubling frame provided with our improved four-fold and roller lap preventer. Figs. 5 and 6 are respectively a sectional front view and an end view of the said preventer enlarged.
Similar letters refer to similar parts throughout the several views.
In carrying out our invention and referring to Figs. 1, 2, 3 and 4, a is the bottom and b the top roller, 0 the roller cap-bar, d, e, g the said trap, 71, the tumbling weight, and 2', Zc,-Z the arm fulcrumed thereto. The said trap is carried by a bracket m which may be hooked or secured to the top roller cap-bar a (or any other suitable part of the frame) and may be in the form of a boss d, see more particularly Figs. 5 and 6, which has a cut 6 half way across for the thread a to pass through and longitudinally a screwthreaded hole f extending from one end of the boss (Z through to the cut 6 and containing a screw-threaded spindle g to the outer end of which is secured the tumbling weight h, the side of the said out opposite to the free or inner end of the said spindle forming a nipping surface for the thread 71 against which the said free or inner end operates. In the present instance the said weight arm is made in three parts, the part 2' having a spiral eye 0 and being adjustably secured to -the part in and the latter pivoted to the part Z. The part Z has a rearwardly extending projection 39 adapted to normally bear underneath the cap-bar 0, see Figs. 2 and 3, and thereby take the pressure of the tumbling weight 71, and arm part Z off the thread a.
If desirable the part of the boss d against which the screw-threaded spindle g operates may contain a screw as shown in Fig. 5, the inner end of which forms the said nipping surface so that the latter can be adjusted in relation to the free or inner end of the spindle g and thereby wear may be compensated for.
The four-fold and roller lap preventer described operatesas follows: While the thread a; is intact, the relative position of the parts composing the said preventer is such as shown in Figs. 1 and 2, namely the front end of the part i of the arm i, 70, Z rests upon the thread a, the screw-threaded spindle g is slightly withdrawn and allows the thread to freely pass through the out 0, the tumbling weight it is approximately in an upright position and the projection 79 of the arm-part Z bears underneath the roller cap-bar 0. When the thread breaks, the arm parts i and 70 drop, the latter upon the bottom roller a as shown in Fig. 3, and being thus in frictional contact with the roller a it is moved back thereby, which causes the other part of the arm to push the tumbling weight it over its center and thus turn the screwed spindle g inward and nips the thread in the cut e, as shown in Fig. 4. After the thread has been pieced, the arm 2', is, Z and tumbling weight it are brought back into their normal position as shown in Figs. 1 and 2.
We claim:
1. In a ring and flier doubling frame, a stationary surface in the path of the thread at the back of the rollers, a screw-threaded spindle opposite to the said surface and means under the control of the thread for turning the said spindle and thereby press the thread against the said surface and nip the thread when it breaks, all combined substantially as and for the purpose set forth.
2. In a ring and flier doubling frame, a bracket at the back of the rollers having a boss and a cut across the said boss forming a stationary surface, a screw-threaded spindle in the said bracket opposite to the said surface and means under the control of the thread for turning the said spindle and thereby press the thread against the said surface ancl nip the thread when it breaks, all combined substantially as and for the purpose set forth.
3'. In a ring and flier doubling frame, a stationary surface in the path of the thread at the back of the rollers, a screw-threaded spindle opposite thereto, a tumbling weight secured to the said screw-threaded spindle and an arm fulcrumed to the said Weight projecting over the bottom roller forward and supported by the thread when intact,
all combined substantially as and for the purpose set forth.
f. In a ring and flier doubling frame, a stationary surface in the path of the thread at the back of the rollers, a screw-threaded spindle opposite thereto, a tumbling weight secured to the said screw-threaded spindle, an arm fulcrumed to the said Weight projecting over the bottom roller forward and supported by the thread when intact, the said arm being formed in three parts pivotally connected together, the parts fulcrumcd to the said weight having a rearwardly extending projection, all combined substan tially as and for the purpose set forth.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
