Title: Apparatus for winding yarn
IPC: D01H1/36
Filed: 1961-01-10
Abstract: 943,750. Converting rotary into reciprocating motion. MONSANTO CHEMICAL CO. Jan. 10, 1961 [Jan. 21, 1960], No. 1071/61. Heading F2Q. [Also in Division D1] A mechanism for converting rotary motion into reciprocating motion to guide yarn on to a bobbin, comprises a traversing block 18 slidable along guide rods 15 parallel to the axis of the bobbin, a driven belt 40 having opposite spans parallel to the guide rods 15, and a gripper block 50 that is slidable in the traversing block 18 for alternately gripping the opposite spans of the moving belt 40 to cause the block 18 to be reciprocated. The movement of the gripper block 50, within the traversing block 18, is controlled by a circular cam 60 pivoted eccentrically at 61 so as to have a snap-over movement under the biasing action of a spring 69. The cam 60 is controlled by a bar 77 having a notch 76 into which extends a pin 75 carried by the cam 60. At the instant shown the gripper block is in its left-hand position and the traversing block 18 is carried downwardly by the left-hand span of the belt 40 until the lower end of the bar 77 abuts a lower striker plate 17. The bar 77 is thus displaced to cause the cam 60 to snap-over to its right-hand position and, as a result, the gripper block 50 is moved to the right to grip the right-hand span of the belt 40 and cause the traversing block 18 to be carried upwardly by the belt 40. The upper end of the bar 77 eventually abuts an upper striker plate 16 and the resulting displacement of the bar 77 causes the cam 60 to snap-over to its original left-hand position so moving the gripper block 50 against the left-hand span of the belt 40 to cause the traversing block 18 to be moved downwardly again. As the winding of the bobbin progresses the striker plates 16, 17 are slowly moved towards each other by a screw 30. The screw 30 has its opposite ends threaded in opposite directions and is connected to the striker plates 16, 17 by spring-loaded jaws 32 on the plates 16, 17.

Title: Improvements in Weft-winding Machines.
Inventor: SCHAUFELBERGER ALBERT
IPC: B65H54/20
Filed: 1918-01-19
Abstract: 112,783. Schaufelberger, A. Jan. 19, 1917, [Convention date]. Winding-machines; stop-motions; driving-arrangements.-In a pirn-winding machine in which the spindles are arranged around the circumference of a circular frame and are driven by a commou gear, the threads are traversed by a common cam mounted on the same shaft as the gear. The pirns 25, Fig. 1, are mounted upon spindles 19, which are depressed as the pirn grows by its engagement with a cone 34, Fig. 4. The spindles pass through driving-sleeves 17 which engage gears 14 meshing with a common gear 10 mounted on the shaft 8. The traverse cam 37 is formed ou the edge of a plate 9 on this same shaft, and is driven by a friction gear 11 adjustable along the main driving-shaft 12. The edge of the plate 9 may have more than one undulation and may be changeable. The spindles 19 are supported in sleeves 16 and in movable supports 23 which rise and fall in fixed guides 26 and are held up by weights 33. The conical layer being wound is pressed by these means against the core 34 which is mounted on a pin 61 adjustable in a slot 60, and held against a stop 57 by a spring coiled round the pin 61. The thread passes through a guide below the edge of the cam 37 and over the edge to the pirn. When a thread breaks, it allows an angle-piece pivoted on the thread-guide to move and depress a rod 49, Fig. 6, bringing an arm 48 into engagement with a cam part 53 on the cam plate 9. This operates a weighted three-armed lever 39 and withdraws a notch 40 from the stoprod 22, which thereupon rises under the influence of the spring 42 and takes the driving-sleeve out of engagement with the gear 14. When the pirn is full, a tappet 54 on the movable support 23 engages the inclined end of a lever 43 and presses it to the right, causing it to carry with it by means of a projection 44 the lever 39 and thus release the stop rod 22. The horizontal handle at the top of the stop rod at the same time engages the stop 57 and raises the lever carrying the cone 34 and moves it out of engagement with the pirn. The pirn then rises under the influence of the weight 33 into position for it to be exchanged.

Filed: 1916-01-28
Abstract: 100,668. Lanston Monotype Corporation, (Lanston Monotype Machine Co.). Jan. 28,1916. Strip perforating machines; keyboards.-Relates to repeat-mechanism whereby the parts corresponding to a selecting-member are automatically continued in action. Improved means is provided for automatically arresting the repeat-action at predetermined points in the line. The valve bars 173, Fig. 1, of the machine described in Specification- 17199/08 have at their inner ends yokes 16, Fig. 6, in which are pivoted bellcrank levers 18 by which the valves are operated. The levers 18 can be oscillated to repeat a signal by a repeat-bar 19 which is reciprocated by a separate motor operated as described in Specification 7248/15. The bar 19 is normally held raised by a catch 27, Fig. 2, in which position it merely serves as a guide for the lower arms of the levers 18. The catch 27 is carried by a lever 29, Fig. 7, controlled by a spring-pressed rod 32, and is depressed to start the repeat action by means of a repeat-key which acts through a lever 36<a>, rod 38, and plate 40 on a collar 35 on the rod 32. The repeat action is arrested by stops adjustably mounted on a rod movable endways and carried by the em-scale. Contact between one of the stops and the em-scale pointer causes a lever 45 to raise the plate 40 and' release the collar 35, whereupon the latch 27 is moved into operative position by the action of the spring 33. The adjustable stops are normally out of the path of the em-scale pointer and are moved into its path by the endlong movement of the rod 38.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B19/04
Filed: 1942-02-03
Abstract: 549,195. Photographic roll-film cameras. KODAK, Ltd. Feb. 3, 1942, No. 1440. Convention date, Feb. 10, 1941. [Class 98 (i)] A roll-film camera includes means which normally latches a shutter actuating means against operation, means adapted to be connected to and operated by a film-feeding mechanism to release the latch when the film is fed, and a single manually-operable means for disconnecting the latch releasing means at any time from the film-feeding mechanism and actuating it to release the latch from the shutter-actuating means. The invention is particularly applicable to roll-film cameras in which a cut-film adaptor back may be used, the film-feeding mechanism being then inoperative. The mechanism shown is the same as that described in Specification 548,754, in which a spring latch 63 latches the shutter release member 28 against operation until, as shown, it is disconnected from it by the movement to the right of a lever 54. This movement occurs when the lever 54 is connected to the film-feeding mechanism near the end of the feeding operation, by the engagement of a lug 53 on the end of the lever in a slot 50 in a disc 49, so that slight further rotation of the disc which occurs as the winding is completed moves the lever to the right. As described in Specification 548,754, the shutter is normally set by means operating in conjunction with the film-winding means but it may be independently set by the movement of a lever 73 manually operable from the exterior of the camera. According to the present invention, an arm 76 on this lever has a cam portion 80 which engages a pin 79 on the lever 54 so as first to turn it to release the lug 53 from the notched disc 49, and then to move it to the right to disengage the spring latch 63 from the release member 28. The shutter may thus be released as well as set independently of the film-feeding mechanism.
