Title: Improvements relating to brake and clutch mechanism particularly for hoisting drums
IPC: B66D1/14
Filed: 1937-10-12
Abstract: 505,758. Brakes for winding and paying-out apparatus. FOSTER, W. W. Oct. 12, 1937, No. 27738. [Class 78 (v)] [Also in Groups XXXIV, XXI, and XXIV] In combined brake and clutch mechanism, particularly for a hoisting drum, a brake band concentric with the clutch and adapted to be tightened upon rotation of the drum in one direction is applied to a flange on the driven clutch member which is secured to the drum and is moved, axially with the drum to engage the driving clutch member. The brake band may be normally applied by a weight and be controlled by a handle rotatable on the clutch control lever. The hoisting drum 11 of a draw-works is freely mounted by bearings 13 on a sleeve 5 secured to a normally rotating shaft 1. The drum 11 carries a clutch flange 10 for engagement with a driving clutch drum 8 integral with a spool 3 secured to the sleeve 5 and thus to the shaft I. Axial movement of the drum is effected by turning a ring 18 which abuts on a flange 12 of the drum and between which and a ring 15 are a series of pins or struts 17 which upon turning the ring 18 to engage the clutch are moved from a position oblique to the drum axis towards a position parallel to that axis. The ring 15 bears on a collar 14 secured to the sleeve 5. The ring 18 has toothed engagement at 55 with a hand-lever 51, 53 mounted on a pivot 44 in a stationary part 33 secured to the post 2. A brake band 34 of two parallel turns secured together at the middle point is applied to a flange 24 integral with the clutch flange 10. One end of the band 34 is anchored at 36 to a stationary casing 25 and the other end has a rack 37 geared to a pinion 38 on a shaft 39 mounted in the casing and the part 33. The shaft carries a pulley 45 having teeth geared to a bevel wheel 49 secured to a tubular shaft 50 which can be turned by handles 52 about the lever 51. A moderate tension is normally applied to the brake band by a weight which is suspended by a chain 46 from the pulley 45. This tension is sufficient by reason of the self-energizing action of the band, to prevent reverse rotation of the drum but it can be increased or diminished for controlling the drum by turning the shaft 50 while the clutch can be engaged and disengaged by moving the lever 51. The brake band may be held disengaged by a detent 40 pivoted at 42 and engaging a notch in the rack 37. The casing 25 which is supported by the bearing 27 upon and moves laterally with the drum 11. is prevented from rotation by a vertical link 30 by which it is connected to a projection 32 on the part 33.

Title: Improved safety fastening for carriage doors and the like
Inventor: TAYLOR JOSEPH ERNEST
IPC: E05C1/16
Filed: 1959-08-14
Abstract: 924,264. Latch fastenings. J. E. TAYLOR. Aug. 11, 1960 [Aug. 14, 1959], No. 27873/59. Class 44. A safety fastening for carriage doors and the like includes a lock having two bolts 3, 4, a keep 18 and a safety catch 15 associated with the keep, wherein one bolt 3 of the lock is held by a ratchet 5 and cannot move except by closing the door or turning the handle 13 so that such bolt cannot vibrate free of the safety catch and only when the door is locked or fully open in the handle in its normal and usually horizontal position. As shown, the bolts 3 and 4 are biased to their fastening position by springs 8 and 10 and the bolt 4 is retracted by a pinion 6 connected to the handle 13 which engages a rack 19 formed in the bolt 4. When the bolt 4 is retracted it bears against the ratchet 5 and pivots this so that it frees the bolt 3 for retraction. This is accomplished by the engagement of a projection 20 on the bolt 3 with a slot in the bolt 4. When the door is pushed to close it the bolt 4 engages a sloping face 14 of a striking plate on the keep and is pushed back into the lock; this disengages the ratchet 5 from the bolt 3 and further closing of the door then brings the bolt 3 into contact with a sloping face 14A of the striking plate and both bolts are then forced back into the case until they reach the recess of the keep 18 when they can move to their fastening position. If either of the bolts fails to enter the keep 18 the projection 20 on bolt 3 fouls either the face 21 or the face 22 of the slot in the bolt 4 and this prevents the handle returning to its normal position. If the door is not fully closed or is accidentally partly opened the bolt 3 slides along the striking plate face 14 until checked by the safety catch 15. Just prior to reaching this position the bolt 4 travels forward along the striking plate face 14 sufficient to release ratchet 5 which under the action of its biasing spring 11 engages the bolt 3 and prevents it moving away from the striking plate to ensure that it is checked by the safety catch to hold the door.

KINZLER, [trading as MASCHINEN-FABRIK ALFING KESSELER KOMM-GES.]. Aug. 17, 1960 [Aug. 19, 1959], No. 28545/60. Heading H5H. A crankshaft 16 to be heated incidental to hardening is conveyed by a chain conveyer 5 to a heating station at which it is engaged, raised and rotated by spindle heads 14. A pivoted lever 31, swung into the path of revolution of a crank-pin 18, is rigidly connected to a control lever 34 which operates limit switches 37 and 40 to halt the rotation of the crank-shaft in the correct angular position for engagement of the crankpins 18 by inductors 15 which are lowered by motors 41 and 42 and are suspended so as to participate in the orbital movement of the crankpins when rotation is re-commenced. The crank-shafts are fed to rests 8 on the conveyer 5 from rests 10 on a preliminary conveyer 9, both conveyers being driven intermittently. On completion of the heating the crank-shaft is quenched by a medium from a chamber in each inductor and is then dropped back on to the conveyer 5 which is operated to convey the crank-shaft either to a rest position 63 or to the second heating station where the same process is performed, e.g. on the main bearing portions of the crank-shaft.
