Title: Improvements in or relating to drum-winding machines
IPC: B65H54/52
Filed: 1925-04-03
Abstract: 254,398. Wade, H., (Universal Winding Co.). April 3, 1925. Winding-machines.-In a, drum winding-machine of the type described in Specification 205,550, each cop-spindle 48 is pivotally mounted on a carriage 25 which is slidable vertically to the shaft 4 of the winding-drum 5. The carriage 25 is mounted on a frame-member 20 by studs 28 slidably fixed in a slot 23 in which fit rollers thereon. On a stud 34 on the carriage is pivoted a member 40 in the horizontally-bifurcated end of which is pivoted the spindle 48. The member 40 is tilted on its pivot by the engagement with a groove 61 in the frame-member 20 of a crank 60 on an arm 55 of the member 40. The crank 60 is adjustable in the arm 55 to regulate the initial tilt of the spindle 48. The carriage 25 initially rests on an adjustable screwed rod 65. A lug 69 on the carriage 25 slides on a rod 70. When the cop is completed, the lug engages an adjustable collar 72 on the rod 70 to raise the rod and stop the winding-operation. A toothed plate 75 on the carriage 25 co-operates with a pawl on the machine frame to prevent downward movement and also acts as a medium for raising the carriage to stop the winding operation. The spindle 48 is normally held in the vertical plane of the shaft 4 by a spring-member 51 but can be displaced for renewal of the cop-tube 50. The yarn is led over a bail 18 to a thread-guide 15, 16, which is reciprocated on a rod 14 by a camgroove 9 in a cam-member 8, the groove being shaped to increase gradually the taper of the cop in accordance with the tilting of the spindle 48. The tilting also displaces the spindle to the left so that the base of the cop become convex and the apex end concave. In a modification for building cylindrical cops, the arm 55 of the member 40 is dispensed with, and the member 40 is positioned to hold the spindle 48 always horizontal by a collar fixed on the stud 34 and splined to the member 40. The thread-guide is also reciprocated at constant speed from a second cam-groove 10 on the member 8.

Abstract: 594,423. Looming warps. ZELLWEGER, Ltd., FACTORIES FOR APPARATUS & MACHINES USTER. April 11, 1945, No. 9054. Convention date, April 21, 1944. [Class 142 (ii)] A device for separating warp stop-motion blades from a staple of blades in warp preparation machines is characterised in that a knife co-operates - with the separating member in such a manner that the knife edge engages with the staple directly behind the blade to be separated. In the device shown, four .staples of blades are provided, and each separating member is in the form of a magnet 3 the distance between which and its-corresponding knife 10 is adjustable by a screw 31 according to the thickness of the blade 2. The knives are controlled by axial displaceably-mounted plungers 12 the movement of which is determined by staggered projections 15<1> on an exchangeable roller 15 which is rotated by pawl and ratchet mechanism co-operating with a connecting rod 21 and crank 20. When a projection 15' engages a plunger 12, the corresponding knife 10 is swung into an inoperative position. The magnets and knives are rotatably mounted about an axle 5 and have swinging motion imparted thereto by means of the crank 20 and a connecting rod 22 and link 25. The magnet moves from a looming position, Fig. 5 (not shown), where the blade is threaded, into a terminal position, Fig. 6 (not shown), where the blade is ejected, then into the blade-grasping position shown before returning to the looming position to complete a working cycle; the knife, however, after having intruded behind the blade to be separated is brought to a standstill by means of a disc 12<11> on the plunger 12. In the case of a staple of blades from which the foremost blade is not to be separated in the respective working cycle, the knife intrudes between the magnet and the foremost blade. The device may be used for separating open-ended blades for the purpose of putting them on separated warp threads. The magnets may be replaced by suction heads.
