Title: Improvements in and relating to machine attachments for screwing up nuts, studs and the like
IPC: B25B23/14
Filed: 1928-05-25
Abstract: 294,232. Chicago Pneumatic Tool Co., (Assignees of Meunier, L. F.). July 22, 1927, [Convention date]. Attachments for assembling or inserting bolts, nuts and screws.-A yielding drive chuck for screw-driving, stud-setting, &c. forms an attachment to a rotary spindle and comprises driving and driven elements in telescopic relation and having limited axial movement, opposing portions of the elements being provided with replaceable clutch parts. A rotary spindle B mounted in bearings in a casing C, which may form part of a staticnary or a portable machine, is provided with a polygonal end b engaged by a similar bore in a sleeve 15. A second sleeve 16 has a portion 17 slidable and rotatable within the sleeve 15 and a bore rotatably mounted on a reduced extension b<1> of the spindle B, opposing flanges on the sleeves being provided with replaceable clutch dogs 15<b>, 16<b> which are push fits in axial bores in the flanges. The dogs 16<b> have parallel sides while the dogs 15b preferably have divergent sides, as shown in Fig. 6, the edges in each case being bevelled to facilitate slipping. A spring 20 housed in a bore b<2> of the spindle B engages a plug 22 retained in the sleeve 16 by a pin 23 to force the clutch dogs apart within the limits imposed by a divided stamped metal casing 18. A spring 19 keeps the casing together and a flange 15<c> on the sleeve 15 engages an inturned flange on the casing. The device is retained on the spindle B by a ball detent 27 pressed into an annular groove b<3> in the spindle by a sleeve 28 normally depressed by a spring 29 engaging a collar 30 secured to the sleeve 15 by a ring 31. In operation, axial pressure of the work on the screw-driving &c. tool causes the. clutch to be engaged against the spring 20, the driving pressure being determined by the angle of the bevelled edges of the clutch dogs. In a modification, the clutch dogs consist of annular rings of teeth 35<a>, 36a attached to the sleeves 35, 36. The rings are a tight fit on the sleeves and are further secured by flattened portions 35<d> &c. on the flanged ends of the sleeves engaging similarly shaped recesses in the rings. A split metal stamping 38, held together by a spring ring 39, has inturned ends engaging flanges on the rings to limit their axial movement, and the teeth 35<b> are bounded by radial sides while the teeth 36<b> have parallel sides. Sockets. - The tool is held in a socket 16<c>, Fig. 1, on the driven sleeve 16 by a ball 24 pressed inwards by a sleeve 25 actuated axially by a spring 26.

Title: Improvements in Pliers, Pincers, Tongs, and the like, and in the Manufacture of the same.
Inventor: WILLIAMS MORGAN LLOYD
IPC: B25B9/02
Filed: 1917-10-27
Abstract: 119,313. Williams, M. L. Oct. 27, 1917. Pliers, pincers, tongs and like tools are formed of wire, the pivot of the tool being formed by bending each part to form a loop, the two loops being interlocked. Fig. 1 shows one form of tool formed from a single length of wire bent to form handle parts b, c and gripping arms b<2>, c<2> with gripping ends b<3>, c<3>. Interengaging loops b<1>, c<1> form the pivot and the resiliency of the wire normally holds the ends b<3>, c' in gripping position. In another form, Fig. 2, the pivot is formed by double loops b<4>, b<5>, c', c<5> and the gripping ends b<3>, c<3> are normally open. In another form having a single loop pivot as shown in Fig. 1, the arms b<2>, c<2> are cranked so as to cross. In another form, the arms b, care cranked to cross each other. In a further form, Fig. 5, the wire is cranked adjacent to the pivot joint.

Title: Improvements in or relating to thread or wet winding systems
IPC: B65H59/38
Filed: 1949-07-01
Abstract: 674,820. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. July 1, 1949. [July 2, 1948] No. 15649/51. Divided out of 674,744. Class 38 (iii). [Also in Group XXXV] The tension in a moving web is controlled by variation in a loop length which alters the coupling between two coils to control the speed of the thread winding motor. As shown, variations in the length of a loop of thread between rollers 15, 16 passing through an eye 17 on a weighted arm 18 rocks a bar of magnetic material 31 to reduce the coupling between primary and secondary coils 30, 24. The secondary output is applied through a rectifier 26 to produce a blocking bias across a capacitor 27 in the grid circuit of a thyratron 23 connected across two lines of a poly-phase threadwinding-motor 12. As the loop length decreases, the blocking bias is reduced and the valve 23 conducts to unbalance the motor excitation and reduce its speed. In a modification, Fig. 4 (not shown), the coupling between the coils increases as the loop length decreases, and the valve (with a reversed rectifier in parallel) is in series with one phase of the motor (shown as a two-phase capacitor motor). Specification 674,744 is referred to.
