Patent GB-624872-A (GB)
Title: Coupling device for two co-linear shafts
IPC: F16D1/05
Filed: 1946-08-28
Abstract: 624,872. Shaft couplings. MANUFACTURE DE MACHINES DU HAUT-RHIN. Aug. 28, 1946, No. 25757. Convention date, Aug. 1, 1939. [Class 80 (ii)] A coupling for co-axial shafts, having a space between them for the removal of components mounted thereon, comprises a sleeve capable of sliding without turning on the shaft ends and having a conical female part engaging a corresponding male portion on one shaft, locking means being provided for preventing longitudinal movement. A sleeve 7 is located axially in a bearing 6 by a shoulder 11 and a collar 12 and is grooved internally to slidingly engage keys 8 and 9 on driving and driven shafts 2, 1 respectively. To engage the coupling, the bearing 6 is moved to the left allowing the female part of the sleeve to engage with the corresponding male corner 13. The sleeve is then locked by the tape threaded nut 15 which contracts the slotted end of the sleeve on to the shaft 2. In modifications the locking is performed by a parallel thread and plain taper in place of the nut 15, and by right- and left-hand thread connections between sleeve 7 and the shaft 1, and by a nut on a shaft 1 having an extension which clamps behind a shoulder on the sleeve 7. The two latter locking devices are reversible to disconnect the coupling.

Title: Thread cutting mechanism for sewing machines
IPC: D05B65/00
Filed: 1925-10-15
Abstract: 250,113. Fairweather, W., (Singer Manufacturing Co.). Oct. 15, 1925. Buttonhole sewing-machines; thread-cutters and thread-end holders.-Means are provided for engaging and severing the underthread and pulling off a length of slack thread after severance. The device is described as applied to a buttonhole sewing-machine of generally known construction and having a control shaft 58 which performs a partial rotation before and after sewing the second partial rotation effecting the cutting of the thread and opening of the work clamp. A lever 62 carrying the thread-cutting and gripping devices is actuated through a pin and slot connection by a slide 66 moved by a cam 81 on the shaft 58. A jaw 68 having a gripping face and thread-cutting edge is mounted on the lever and co-operates with a jaw 71 formed on a secondary lever 70 pivoted with friction at 71 on the lever 62. When the lever 62 is moved towards the thread the latter slips over the nose 89 of the lever 70 which is thereupon moved to grip the thread by the engagement of a stud 90 with a cam edge 91 on the slide member 66. By the continued movement of the lever 62 the thread is sheared against a stationary blade 78 and thread is then drawn from the bobbin and falls slack on the return movement of the lever. The thread is still gripped by the jaw 72 but after a few stitches of the ensuing sewing operation a lever 94 operated by a cam 93 on a feed-wheel 46 engages a stud 96 on the lever 70 and opens the jaw. The needle-thread is cut by a usual cutter on the clamping foot of the machine. In the machine shown in the drawing a laterally vibrating needle is employed, the actuating Shaft for the jagging movement being driven by a starwheel as described in Specification 250,112.

Title: Improvements in or relating to bale discharge means for hay balers
IPC: A01D87/12
Filed: 1961-07-18
Abstract: 917,538. Baling machines. INTERNATIONAL HARVESTER CO. July 18, 1961 [Nov. 17, 1960], No. 25967/61. Class 94(1). A bale discharge means for a hay baler comprises a roller supporting frame adapted for attachment to the discharge portion of a baler, upper and lower rollers carried on the frame and arranged to receive between them a bale discharged from the baler and convey it upwardly at an inclination, and means for driving said rollers at an appropriate speed so that the bale is pitched on a trajectory for delivery into a trailer. The bales as they leave the baling chamber 10 pass up an incline 26 and are conveyed upwardly between upper and lower sets of rollers 52, 53, 54 and 45, 46, 47 which accelerate them and project them into a trailer 30. The rollers are rotated by a continuously driven V belt 42 which is connected via a pulley 41, a gear box 21 and a telescopic shaft 19 to the drive take off shaft 15 of a tractor. A crank 16 is used to drive mechanism (not shown) for packing harvested hay into the bale chamber 10. The belt 42 passes over an idler pulley 43 mounted on a rod 89b which slides within frame member 51 and pulleys 58-60, one for each roller. The pulley 43 can be moved upwardly to tighten the belt by pulling on a rope which extends to a tractor, a spring causing downward movement of the pulley when the tension of the rope is reduced. Each of the roller pulleys comprises a plate 74 mounted rigidly on the shaft 84 and a second plate 77 keyed for longitudinal movement with respect to the shaft 84 and biased towards the first plate by a spring 79. When the rope is pulled to tighten the V-belt the springs 79 are compressed and plates 74, 77, move slightly apart and thus reduce the effective diameter of the pulleys and increasing their rate of rotation. Each roller comprises discs 83 of fabric reinforcad rubber mounted on a spindle 84 supported by self aligning bearings 50. A spacer block 99 is provided between the first and second lower rollers 45 and 46 to facilitate free upward motion of the bale. The roller speed may be adjusted by a change in the gear drive so that the bales are pushed out slowly for manual loading.
