Title: Improvements in or relating to die presses for working metal
IPC: B21D22/00
Filed: 1939-06-20
Abstract: 530,188. Forging wheels and discs. SCHLOEMANN, AKT.-GES. June 20, 1939, No. 17977. Convention date, July 9, 1938. [Class 83 (iv)] In a metal working press, such as a hydraulic press for making wheels and other circular bodies, in which one or more of the co-operating dies 5, 6 is or are changed during working on one and the same blank 9, a workholding device 10 is operatively associated with a movable part of the press so as to be moved into engagement with the work to lift it and hold it clear of the dies when the latter are opened the operation being reversed when the dies are closed. The clamps 10 are slidably mounted on hollow sockets 11 within which are mounted levers 12 engaging the clamps and held in the open position by counter-weighted levers 14. The sockets rest on plungers 15 of limited stroke subjected to constant hydraulic pressure and are connected to sleeves 29 mounted on the columns 3 and abutting the cross head 4. The levers 14 are coupled by rods 20 to one arm 23 of a bell crank, the other arm of which engages a piston rod 26 sliding in hydraulic cylinders 27, 28 subjected to controllable and constant pressure respectively. A resilient abutment member 21 on the rod 20 engages a fork-like projection 22 on the cross-head. When the dies are separated the clamps move upward and inward to grip the blank and then lift it clear of the lower die. This operation is reversed on closure of the dies. The rod 20 makes a pin-andslot lost motion connection with the arm 23 and by increasing the pressure in cylinder 27 the rod 20 is moved into an inclined position to free the abutment 21 from engagement with projection 22 and render the work-handling devices inoperative.

Title: Improvements in and relating to clothes washing machines
IPC: D06F37/30
Filed: 1942-12-22
Abstract: 573,874. Washing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 22, 1942, No. 18210. Convention date, Dec. 31, 1941. [Class 138 (ii)] [Also in Group II] In a machine for washing and centrifugal drying, the gearing driven by the motor is mounted on the central axis of the tub in a housing frame which is held to give slow speed for reciprocating the agitator vertically and freed to rotate with the frame and gearing as a whole and give the fast speed for drying. The vertically-reciprocating agitator is a cup 17 attached to a hollow shaft 19 connected to a Scotch yoke 44 and slide 45 in which works the crank pin 37 carried by a bevel gear 35 meshing with a bevel gear 34 on a shaft 33 attached to a motor driven pulley 32. The shaft 33 is journalled in the lower part 23 of a spherical casing 22, 23 which has also pressed-in bosses 41 to carry pins 40 on the inner ends of which is journalled the crank shaft 36, the arm 39 of which is drilled to take the pin 37. The upper part 22 of the casing is secured to the hollow shaft 13 which has a reduced section 12 on which is seated fast the hub 11 to the lower flanged end 10 of which are secured the radial arms 9 of a heavy annular carrier 8 supporting the tub 5. The tub rests in the carrier with a rubber bushing 14 engaging the hub 11 to prevent leakage. The hollow shaft 13 has above a bearing 20 for the agitator shaft 19 and rests below on a roller thrust bearing 26 arranged between a sleeve 27 on the upper spherical casing part 22 and a sleeve 24 which also has a bearing 25 above for the hollow shaft 13. The sleeve 24 is attached to a spherical member 68 resting on friction members 71 on a spherical surface 72 of a ring 48 situated in a hole in the floor of the casing 1 to which its flange 48a is bolted. Between a ring 69 secured by the same bolts and a flange 67 on the surface 68 is located a rubber ring 66 which thus gives resilient support to the tub, the vibrations of which are damped by the friction members 71. The same bolts also secure a ring which clamps the edge of a flexible rubber seal 27a, the upper end of which is clamped by a ring 27b to the sleeve 24 to prevent leakage. During washing, the housing 22, 23 is held stationary by a friction pad 50 on a ring 49 swung on diametrically-opposite studs 47 on the fixed ring 48 and pressed upward by springs 51 on the studs. In this way the crank 39 is driven to work the agitator at a rate of 250 strokes of about 1¢ inch a minute. For drying, a lever 54 is moved to press down the ring 49 and free the housing 22, 23 which thereupon increases in speed until a centrifugal clutch 59, 60 couples it directly to the pulley 32 bringing the speed to 1,200 r.p.m., the friction at 68, 71 and resilience at 66 causing the tub to rotate nearly about its centre of axis and lessening the vibration.

Title: Improvement in delay action blasting detonators and the like
IPC: F42B3/16
Filed: 1931-06-24
Abstract: 383,650. Blasting fuzes ; explosives. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Hercules Powder Co. ; 900, Market Street, Wilming- ton, Delaware, U.S.A.) June 24, 1931, No. 18276. [Classes 9 (i) and 9 (ii).] The igniting charge or the timing train of a delay-action fuze or detonator is composed of an oxidizing agent such as barium peroxide, potassium chlorate, and potassium permanganate and an element of the right-hand column of group VI of the Periodic System such as sulphur, selenium, and tellurium, the said element being chosen with reference to the said oxidfzing agent so that the composition on combustion will produce no substantial quantity of gas and the casing of the fuze or detonator may therefore be ventless. An inert material such as barium oxide and magnesium oxide may be added to control the rate of burning of the composition. The rate of burning depends on the ingredients, their grain size, and the loading pressure. A suitable composition is a mixture of 85 per cent barium peroxide and 15 per cent selenium, each passing a mesh of 150 and loaded under a pressure of 5000 lbs. per square inch ; this gives a burning rate of 60 seconds per foot. The delay-action detonator, Fig. 1, comprises a detonator B containing a charge of mercury fulminate or a charge of tetryl primed with mercury fulminate, a delay fuze C containing a composition d of the kind stated above in a copper tube e wrapped in cloth f, and an electrically fired igniting charge H also of the kind stated above in a recess in a sulphur plug G covered with a waterproofing material I such as paraffin and sealed by a sulphur plug J. The ignition wire n may be coated with a mixture of diazodinitrophenol and potassium chlorate with a small quantity of a binder such as nitrocellulose. In a modification, Fig. 2, suitable where a certain amount of gas is generated, the plug G is a loose fit or is provided with a passage q to lead the gases to an absorbent o such as silica gel or activated charcoal covered by a plug L situated beneath the waterproofing material I.

Abstract: 146,385. Reece Shoe Machinery Co., (Assignees of Schoenky, A. R.). Nov. 8, 1913, [Convention date]. Boot-sole sewing-machines; lock-stitching by shuttles; threads, controlling otherwise than in stitch-forming; presser-bars with periodic control; presser-bar lifting devices.-In an outsolesewing machine adapted to be stopped at the completion of sewing with the under-thread clamped and the presser-foot locked in contact with the work, treadle-operated mechanism is provided for simultaneously releasing the under thread and raising the presser-foot to permit removal of the work. The thread is clamped and the presserfoot locked in each stitch-forming cycle. The presser-foot 23 has a rearward arm 68 connected by a link 71 with an arm 72 fulcrumed on a shaft 73, and is held lightly against the work by a spring 75. Heavy clamping pressure is exerted on the presser-foot in each stitch cycle by a camactuated lever 82, which carries a dog 77 adapted to engage a rack 76. This is carried on a second arm 69 spring-connected to the arm 68, a dog 79 engaging a rack 78 on the arm 68 locking the presser-foot in its lowest position. The dogs 77, 79 are disengaged from the racks to relieve the heavy pressure during feed of the work after each stitch by a fixed pin 85 and the heel 84 of the lever 82 respetively when the lever descends. Manual raising of the presser-foot is effected by the treadle-operated rod 86 carrying a lug 88, Fig. 3. adapted to contact with a lug 74 on the arm 72, the dogs being first disengaged by a plate 90 pivoted on the stud carrying the dog 79 and having teeth engaging teeth on a plate 89 connected to the rod 86 and swung thereby. The under thread is locked, while the take-up 31 sets the stitch and the thread-measurer 119 draws off thread for the next stitch, by a clamp 32 carried by a sleeve 130 surrounding the take-up shaft 124 and having an arm 131 operated by the cam-lever 133. The thread-measurer 119 mounted on the shaft 138 is actuated by an arm 140 having a stud 141 engaging a slot 142 in a link 143 oscillated about a pivot at the end of an arm 144 through a link 145 by a cam-lever 147. In order that the amount of thread measured may be in accordance with the thickness of the work, the arm 144 is mounted on the presserfoot operating-shaft 73 whereby the pivot of the link 143 is varied to impart variable movement to the arm 140. Depression of the treadle rod 86 also opens the thread clamp, and for this purpose the link 132 carries a lug 162 which is engaged by a collar 161 on the treadle rod. The link 132 carries a stud engaging a slot 165 in the arm 131 and normally held by a spring in the upper end of the slot, so that when the lug 162 is lowered, the stud-and-slot connexion causes the arm 131 to be swung to the rear, thereby opening the thread clamp.
