Title: Improvements in or relating to spindles for spinning and twisting machines
IPC: D01H7/04
Filed: 1923-08-08
Abstract: 206,116. Compagnie d'Applications MÚcaniques. Oct. 25, 1922, [Convention date]. Ball or roller bearings; spring supports. The shaft 4 of a spinning-machine spindle is provided at about its mid-length with a dismountable ball-bearing 1, provided with a cage 2, the inner ring 3 of the bearing being secured to the shaft 4 and the outer ring 5 to a socket 7 slidably mounted in the spindleholder 6. The pivot 8, at the lower end of the shaft 4, rests upon a step-bearing 9 which is slidable in the holder 6 under the action of a spring 10. The spring 10 is arranged to exert an upward force which almost counterbalances the downward force due to the weight of the shaft, the weight of the step-bearing, and the vertical component of the tension of the driving-cord 12. The Specification as open to inspection under Sect. 91 (3) (a) describes a spindle supported by a ball or roller-bearing. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the "stuffing" of chrome tanned heavy leather
IPC: C14C7/00
Filed: 1924-08-27
Abstract: 243,438. Pickard, R. H., Lloyd, D. Jordan-, and Caunce, A. E. Aug. 27, 1924. Impregnating.-Stuffed leather is made by steeping chrome-tanned leather in the wet-blue condition in a bath of acetone, or spraying it with acetone, until the water content of the leather is reduced to from 14 to 20 per cent, removing the acetone and steeping it in, or treating it with, a stuffing material. The leather is treated with acetone until a sample cutting dried at approximately 57‹ C. will wet back in water or until the leather is in equilibrium with a water and acetone mixture of specific gravity 0.81. The acetone is removed by subjecting the leather to the action of air, which may be moist, at about 57‹ C.

Title: Improvements in fluid-operated pumps for lubricants
IPC: F16N13/16
Filed: 1936-01-20
Abstract: 474,099. Lubricating-pumps. MARRIOTT, H. L. (Aro Equipment Corporation) Jan. 20, 1936, No. 20567. Divided out of 474,072. [Class 102 (i)] [Also in Groups XVIII and XXVI] Apparatus for dispensing lubricant comprises a wheeled platform 50, Fig. 1, carrying a lubricant container 18 enclosed in a casing 47. The latter is supported on the platform by brackets 57 and is secured by spring latches 54. A pump cylinder 15 projects into the container 18 and the rod 12, Fig. 2, of the bucket 16 is connected to a piston 2 moving in a cylinder 1. Pressure fluid is constantly admitted by a pipe 4 to the space 5 beneath the piston 2 and effects the upward stroke. The downward stroke is effected by admitting pressure fluid to the upper side of the piston 2, which is of greater area than the lower side, owing to an enlarged part 11 of the rod 12. The distribution to the upper side of the piston takes place through a passage 9, Fig. 3, in the cylinder cover 10, a hollow bolt 7 and a passage 30, which is connected either to the cylinder space 5 through a hollow bolt 26 and a passage 29, or to atmosphere by a passage 40. The passages are controlled by a double-beat valve 28, operated by snap-over mechanism engaged by shoulders on a rod carried by the piston 2. The pump draws through a footvalve 21 and discharges through a passage 42 to a meter 44 and hose 45. When the level in the container falls the valve 21 is held open by a pivoted arm 24 operated by a float 25. Specifications 461,213, [Group XVIII], and 474,072 are referred to.

Title: Improvement in boat-launching devices
IPC: B63B23/04
Filed: 1931-07-20
Abstract: 378,179. Boat-lowering gear. AMERICAN SAFETY NAVIGATION CO., 801, Rex Avenue, North East, Canton, Ohio, U.S.A. July 20, 1931,'No. 20731. Convention date, Aug. 4, 1930. [Classes 113 (i) and 115.] The initial luffing movement of the davits releases the gripes and the lashings for the boat covers. The luffing davits 8 are pivoted to the deck at the base of a pillar 3 which carries a guide 10 for one arm 11 of a bell-crank lever pivoted to the davit at 13, the other arm of the lever serving as a support for the boat which is carried on chocks 17, 18. The locking- device for the davits in their inboard position comprises a counterbalanced catch 37, the stem of which is engaged by cam 42, whilst it's tooth 37 is engaged by a hand-operated lever 36, Fig. 1b, in turn locked by a dog 40. The lashings 62 for the cover 60 as well as the fore and aft gripes terminate in rings, all of which are engaged by hooks 67 carried by a rod 66 which is movable longitudinally in a casing 79 carried on the chock supports 12. The gear for moving the rod longitudinally and so releasing the hooks 67 from the rings, comprises a pulley 72 on the end of the rod 66, a pulley 74 on the casing and third centrally disposed pulley 75. A control rope 69 fast on the casing is led round these pulleys in turn and the other end fastened to the standard 3. The initial luffing movement under gravity on release of the fall-gear and the consequent tilting movement of the boat support 12 about the pivot 13 operates through the rope to shift the rod 66 and thus release the boat-cover lashings and gripes. The gripes themselves are carried under the cover and are provided with screwtightening gear. In a modification, Fig. 18, the eyes at the ends of the lashings &c. are hooked over pegs on a shaft 110 which is further provided with spur-wheels 112 engaged by a tooth on an arm 113 brought back to the standard 3 and associated with the locking- gear for the davit so that the tooth 114 is released from the pinion wheel which is then free to rotate and free the lashings.

[Class 139] In a balance spring arrangement for clockwork mechanisms, the balance spring c is fitted with slight preliminary flexure in such manner that it always moves the anchor a, when no driving force is acting on the escape wheel b, into a middle position relatively to this wheel. The Figure shows the anchor in such central position with the tooth Z of the undriven escape wheel b resting against the pallet PA. When power is applied to wheel b, the anchor will be rocked counterclockwise, additionally stressing the left half of spring c. Thereafter, the halves of the spring c are additionally stressed alternately.

Filed: 1938-07-14
Abstract: 509,534. Broaching. STEVENS, A. H. (Sundstrand Machine Tool Co.). July 14, 1938, No. 20894. [Classes 83 (iii) and 83 (iv)] In a broaching-machine, a slide, reciprocated by fluid pressure, has means for the attachment of push, pull or surface broaching-tools. A slide 5 integral with a hydraulic cylinder, houses a stationary piston 16. A pump 7 supplies fluid from a tank 8 to a valve 6 which distributes it by pipes 40, 38 to the bottom of the piston and to the top of the piston through holes 43. A top facing 29 is recessed to receive a holder for a push broaching-tool and a bottom facing 30 positions a pull broaching-tool. An intermediate recessed facing carries a surface broach 26. The workpiece 10 is held in a clamp 11 on a work-table 4. In use, the selected tools are secured to the slide and a lever 45 is swung anticlockwise to lower the piston 43 of the valve 6 to allow fluid to flow through pipes 36, 38 to the bottom of the piston. The cylinder and slide descend and an adjustable stop 56 reverses the valve at the bottom of the stroke. The fluid flow is reversed and the top of the piston is placed under pressure to raise the cylinder. At the top of the stroke an adjustable stop 55 throws the valve to neutral position and the machine stops. Assembling force fits.-In using the machine to perform broaching operations and inserting a bush in the broached hole, a surface broach and a pull broach are secured to the appropriate surfaces and the bush is held in a crosshead on the surface 29. On the downstroke of the slide, the three operations are performed.

Class 106 (i)] An autographic register employing a folded pack 7 of strips of continuous stationery comprises a writing plate 18, a transfer strip, feed mechanism 11 which feeds the strip 7 and any copies thereof over the writing plate and a summary strip arranged below the other strips and adapted to be fed positively by sprocket mechanism 22 operated by mechanism 11, each operation of sprocket 22 moving the summary slip only a relatively small extent compared with the corresponding motion of the top strip. The top strip is fed by teeth 12 on arms 14 driven by a shaft 13. This shaft also carries an arm 25 which rotates sprocket 22 through linkwork 38 and a ratchet 27. The summary strip is fed from a pack 17 and is turned back and caused to fold in a pack 36 by a curved guide 37. The containers and feeding means for the summary strip are constructed so that they can be removed from the apparatus as a unit. Specification 531,351 is referred to.
