Abstract: 171,336. Robinson, A. W., and Marks, H. S. March 7, 1921. Multiple bolt fastenings; locks, revolving- barrel; controlling operation of.-A central disc having integral arms connected by links to bolts, is freed from its locking means by a key, and rotated thereby to operate the bolts, the locking means sliding in a direction parallel to the axis of the disc to bring a gap or gaps in it opposite the bolt-actuating arms. The disc 7 is fixed to the hollow spindle 5 and both have slots 6 and 7' respectively for allowing the insertion of the key into the hollow spindle. ' When the key, Fig. 7, is inserted, the end of the shank presses a rod 25 pivoted to a lever 24 and the end 19<1> of the key bit presses a plate 27 rocking a second lever 24<1>. By pressing home the key, the levers 24, 24' are rocked to depress the cross-pieces 21<1> to which are attached rods 20 and 20'. The pressing in of the key causes a gap 23 in the rods 20<1> to register with the path of the arms 8 and 8<1>, and the bit 19 of the key registers in the slot 28 of the diso 7, so that it is revolved when the key is turned, rotating the arms 8 and 8<1> and operating the bolts. Springs 22 tend to keep the rods 20 and 20<1> in the locking position. Two arms 32 are pivoted to the disc at 33 one on each side of the key slot 7' and form additional locking-means. The arms have heads passing through slots 34 in the disc so that they are pressed by a spring 35 to cause the heads to engage fixed stops 36 on the casing, locking the disc against rotation. The key-bit has projections 37 which, on insertion, engage shoulders 32' on the arms 32 and push their heads out of engagement with the stops 36. Keyhole escutcheons.-Journaled in the front of the door &c. is a circular plate 29 having the keyhole. When the key is pressed home, a flange 31 engages the keyhole in the plate 29, which therefore turns with the key, which is rotated through 90‹ to operate the bolt. The front plate 1 has two key-holes at right-angles to each other, one for inserting the key and one for withdrawing it. As the plate 29 revolves with the key, only one keyhole is necessary.

Title: Improvements in engine starting apparatus
IPC: F02N99/00
Filed: 1932-03-12
Abstract: 401,699. Turning - gear. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. March 12, 1932, No. 7415. Convention date, March 13, 1931. [Class 7 (v).] In an inertia starter, energy is transmitted from the inertia member through a manually actuated self-energising clutch to a friction clutch adapted to yield in case of backfire, thence to a pinion adapted to be moved into and out of engagement with an engine member. Energy may be imparted to the inertia member through a multi-stage gear train, one stage of which also serves to transmit energy from the inertia member to the manually actuated self-energizing clutch. The flywheel 58 is rotated from the hand-crank engaging member 14 through bevel gears 21, 26, and two stages of planetary gearing comprising planet gears 37 mounted on the same shaft as the bevel 26 and engaging a stationary internally toothed annulus 38 and a sun wheel 40; the latter rotates the sleeve 25 carrying planet gears 49 meshing with a stationary internally toothed annulus 50 and a sun wheel 54 to which the flywheel 58 is secured. Energy is transmitted from the flywheel 58 through one of the two stages of planetary gearing comprising sun wheel 54, fixed annulus 50 and planet wheels 49 to the clutch members 60, 61. The latter are moved radially into engagement with the drum 59 by operating a lever 88 to axially displace a rod 83 whose conical end is thereby forced in between the inclined shoulders 82 of the clutch members. The curvature of the friction elements 70 is such as to cause them to be self-energizing, i.e. to wrap themselves along the concave surface of the drum 59. The drum 59 transmits the power through gears 98, 97 to the adjustable friction clutch 111 which will slip under excessive load, and then to the rotatable threaded sleeve 104 carrying a pinion 105 adapted to mesh with the engine member 130 in known manner. The tendency of the clutch members 60, 61 to open under centrifugal force is counteracted by the provision of springs, 77, 78 and diametrically disposed balance weight 80. The housing 5 carrying the hand-crank engaging member 14 has a circular seat and can be rotated about the shaft 25 and. secured by the bolt 12 in any desired position.
