Title: Starting handle for internal combustion engines
IPC: F02N1/02
Filed: 1923-06-05
Abstract: 222,911. Gannon, W. June 5, 1923. Clutches, claw.- In order to disconnect a starting- handle if the engine turns backwards, the hub of the handle 1 carries a screwthreaded clutch pin 6 engaging one of a series of recesses or holes 8 in a disc 3 on the shaft 2. An arrn 9a on the pin 6 is pivoted to a long pawl 9 held by a spring 13 in engagement with a flanged ratchet wheel 11 on the handle grip 12, which is freely rotatable on the handle. In starting, the rotation of the grip 12 relatively to the shaft 2 allows the wheel 11 to slip under the pawl 9. If the engine turns backwards, the wheel 11 engages the pawl and withdraws the pin 6. A stop 14 prevents the pawl 9 from leaving the wheel 11, and an extension 13a on the pawl limits the turn of the pin 6 to the amount required to give clearance from the disc 3.

Title: Improvements in or relating to the production of bricks
Inventor: BENNETT CHARLES LESLIE
IPC: B65G57/26
Filed: 1961-04-24
Abstract: 1,033,151. Stacking; gripping stacks of articles. WOODFIELD BENNETT Ltd. April 19, 1962 [April 24, 1961], No. 14803/61. Headings B8C and B8H. In order to prevent uneven discoloration of stretcher and header faces of bricks during firing, they are stacked on the kiln truck end to end in rows, some of which are separated to provide air spaces, and layers built up so that the rows of successive pairs of layers are at 90 degrees to each other. This results in one stretcher face of each brick being protected from kiln gas by a similar face of a brick above or below it, the end to end alignment protecting header faces. The bricks of one layer of each pair may be inverted 180 degrees so that treated stretcher faces SF, Fig. 3, are brought into contact. The brick separating and arranging apparatus may be substantially as described in Specification 903,440 and 781,263, but the stacking gripper means is modified. The grippers are carried in rows by bars 63-66 mounted on carriages 52, 53, the latter of which may move away from the former on rails 54, 54 to permit rotation of the gripper heads about vertical axes 60, 61. The carriages are jointly movable vertically to raise and lower the bricks. The gripper jaws are pivoted at 80 to the bars and operated by piston and cylinder means 79. Prior to inversion of the bricks, the bars, mounted on rails on the carriages are moved further apart. Piston and cylinder means 71 associated with each bar then turns a shaft 75 which rotates a plate 77 on one of each pair of gripper jaws by chain-and-sprocket means. The opposed plate 77a is freely rotatable and the gripped bricks are thus turned through 180 degrees. Reference has been directed by the Comptroller to Specification 849,805.

Abstract: 818,435. Variable speed gear. VOLVO A.B. May 15, 1957, No. 15478/57. Class 80 (2). A variable speed gear for a vehicle providing two reduced ratio ranges and one reverse, all fluid driven, and an all-mechanical direct drive, comprises a torque converter, the turbine 4 and reactor 5 of which rotate oppositely in first ratio range and are connected respectively to a ring gear 8 and sun 9 (or sun and ring) of a train having planets 10 on a carrier 11 which, for reverse, can be held by a brake 13 whilst the reversely rotating reactor-connected sun 9 (or ring) is clutched to a final output shaft 20 by engagement of dogs 24 splined to the shaft 20, with dogs 25 on a drum 17 carrying an additional sun 16 (or ring) meshing the planets. The torque converter impeller 2 may be, as shown, connected directly to input 1, or the input may drive the planet carrier of a torque splitting train having a sun and ring connected to the impeller and turbine (or vice versa) and a one-way clutch therebetween (Figs. 2 and 3, not shown). For the lowest ratio range, all brakes and a direct drive clutch 21 are released and the output shaft 20 is dog-clutched at 23, 19 (position I) to the turbine 4. The reversely rotating reactor 5 now supplies output torque through the planets, the carrier 11 reacting reversely on a one-way detent 15 to give a ratio range of from 7 to 1 to 2 to 1 between 0 and 35 K.p.h. At 35 K.p.h. a band, cone or disc brake 18 is applied to the sun 16 which thus holds the sun 9 and reactor 5, the converter turbine now driving directly alone, to give a second ratio range of 2 to 1 to approximately 1 to 1 between 35 K.p.h. and 75 K.p.h., after which the clutch 21 is engaged to connect input and output directly. Reverse is as above described in position III of the dog-clutch 22, position II of which locks the output shaft 20 at 27 for parking. The suns 9, 16 may be unequal, (Figs. 6 and 7, not shown), and the planets stepped, or an additional ring may mesh with the planets through planetary idlers, (Fig. 5, not shown). In these cases the brake 18 acts directly on the reactor shaft. The dogs may be replaced by a friction clutch. A speedefficiency curve is given.
