Title: Improvements in and relating to cycle and like locks
IPC: B62H5/14
Filed: 1924-08-11
Abstract: 231,733. Maier, A. Aug. 11, 1924. Guarding against unauthorized use.-Relates to cycle wheel locks in which a lock casing is attached by screws to the rear fork, the screws being rendered inaccessible from the outside by apparatus which is locked simultaneously with the locking of the wheel. The cylindrical casing 3, Figs. 2, 4, 6, and 7, is clamped to the cycle fork tube 16 by means of bolts 17 screwed into the clamping plate 15. The heads of these bolts are concealed by a cap 20 which can only be removed when the look is inoperative. The bolt 6 is slidable in holes in the casing 3, and when shot so as to project between the spokes of the wheel is held in position by the engagement in the notch 9 of a number of spring- pressed fingers 11. To unlock the apparatus, the key shown in Figs. 8 and 9 is inserted into the space between the similarly shaped face of the bolt 6 and the rear hole 4 and thus lifts the fingers 11 and allows the withdrawal of the bolt by the spring 7 until the fingers 11 engage the notch 10. Pins 14. 36 prevent undue movement of the bolt. The boss 21 of the cap 20 is provided with a cross-pin 22 which passes through slots 27 in the central hole in the casing 3, as shown in Fig. 7, when the cap is being placed in position. The cap is then rotated through 90‹ until the pins enter recesses 28 in the inside of the casing 3, and a notch 23 in the flange of the cap coincides with the bolt 6 which, when shot, prevents rotation of the cap. A dust-protecting plate 24 may be provided. Several alternative methods of permanently or detachably securing the cap to the casing are described. When the cap is permanently connected to the casing a hole is provided in the cap through which a tool can be inserted to unscrew the securing bolts after the cap has been rotated into a suitable position. The key may be made with concave depressions on one side and convex projections on the other, so that it may be inserted the right way up in the dark. In the, modification shown in Fig. 19 the securing bolts 17 are completely enclosed. Additional spring catches, disengageable by the key, may be adapted to enter notches in the sides of the bolt. A reflex or other reflector may be carried by the cap.

Filed: 1919-08-08
Abstract: 153,660. Barrett, J. F., Barrett, J. E., and Wyatt, F. A. Aug. 8, 1919. Current motors.-In a propelling device for a windmill, the blades 1, Fig. I, of which there are an odd number, are mounted on pivots in a pair of frames 2, 3 which are carried by a driving shaft 4. A sleeve 5 is mounted rotatably on the shaft 4, as shown in Fig. I, which is a plan view looking upwards. The upper end of the sleeve 5 carries a pinion 7 meshing with a similar pinion 8 which meshes with the pinion 9 whose diameter is twice that of pinions 7 or 8. The pivots of the pinions 8, 9 are carried by the disc 3. The pinion 9 also carries a crank arm 10 having a pin 11 which imparts an eccentric rotary movement to the floating disc 13. The pivots of the blades 1 carry crank arms 12, the pins of which engage the floating disc 13. The relative size of the pinions 7, 8, 9 causes the pinion 9 to rotate on its own axis at half the speed of the shaft 4, while revolving around the pinion 7, and all the crank arms 12 remain parallel to the crank arm 10. The blades 1 are thus feathered during their revolution. The blades may be initially set at any desired angle by means of the worm gear 14, 15, Figs. I. and IV. The worm 15 causes the rotation of the wheel 14 and the sleeve 5 also causes the rotation of the pinions 7, 8, 9 and crank arm 10 to any desired angle. The worm gear may be used as an adjunct to a setting gear in which the sleeve 5 is automatically set in the desired position by means of a long arm 17 carrying a wind vane 18, or the worm gear may be dispensed with altogether.
