Title: Method and machine for performing a cutting action on gear teeth and similar curved forms
IPC: B23F21/28
Filed: 1946-04-10
Abstract: 611,542. Gear-cutting. MILLER, E. W., and FELLOWS GEAR SHAPER CO. April 10, 1946, No. 11056. [Class 83 (iii)] [Also in Group XXIV] A method of cutting the lateral face of a tooth of a gear or cutter &c. comprises effecting a relative rolling movement between a gear-wheel and an edged cutter, the rolling movement being similar to that of a meshing gear and rack, and simultaneously reciprocating the cutter repeatedly in directions transverse both to the translative component of such movement and the axis of the angular component thereof in a path intersecting the curved face of the workpiece, the cutting-edge of the cutter being carried at each reciprocation beyond the intersection points of such path with said curved face. In a machine for carrying out the method, the cutter C, Fig. 1, is mounted on a ram 1 which is reciprocated rapidly by a pivoted toothed segment 13 adjustably connected to a crank 9 on the main shaft 5, Fig. 10. The cutter is carried by a block 22 pivoted in the ram-head and having a cam-end 23 cooperating with a wedge-block 24 which is reciprocated in opposite directions from the ram by means of a piston 27 controlled by a rotary air valve driven synchronously with the crank 9. The wedge-block 24 co-operates with a spring-plunger 25 to relieve the cutter on the non-cutting stroke. The ram 1 is splined in a sleeve 3 which may be rotated by a worm 45 to alter the cutter angle when cutting helical gears. The gear W is mounted on a shaft 51 journalled in a rolling-head 52, Fig. 10, which is itself mounted in a carriage 53 sliding on guides 54. A cam 71 rotated by the main shaft through gearing and a manually-operated clutch, (see Group XXIV), rocks a lever 72 carrying a link 75 which is adjustably pivoted to an arm 57 keyed to the rolling-head 52, which is thus given a rotary movement. Also keyed to the head 52 is an involute cam 58 58 which slides against an adjustable block 59 and imparts a translative movement to the head. The rotary movement is conveyed to the work W by a locking-pin 55, Fig. 1, carried on an arm 56 integral with the rolling head. Relieving from theoretical shape.-By variations of the shape of the cam 58, the inclination of the block 59 and the position of the pivot 76, tooth curves departing from tine involute shape may be generated. Indexing.-Near the end of the return stroke (to the left in Fig. 1) the pin 55 is raised by a pawl mechanism on the arm 56 which rides up an adjustable cam-plate 118 allowing the work to be rotated through one tooth space by a continuously-driven belt running on a pulley keyed to the shaft 51, before the pawl rides off the cam and the pin engages the next tooth. A tensioning device for the belt (see Group XXIV), compensates for movements of the carriage 53. Tools.-A toothed cutter, Fig. 6, may be used for forming gear-shaping cutters by cutting grooves in the teeth faces.

Abstract: 1305765 Prefabricated pools H VIESSMANN 9 March 1970 [13 March 1969 5 Aug 1969] 11209/70 Heading A4N [Also in Division E1] A swimming pool is formed from interconnected wall sections 1 consisting of vertically corrugated sheets of material having at the top of a cap strip 2 and at the bottom a socket strip 3, the inner surface being lined with plastics material such as glass reinforced plastics. Joints between the lining panels 4 and 5 are sealed by an adhesive strip 20 compressed by a bar 19 secured to the socket strip by screws 21. The bar 19 is covered by a rubber or plastics strip 24. A similar sealing arrangement may be used for the corner joints and the bottom joints which are modified as in Fig. 3 (not shown). The cup and socket strip have inner flanges which may be recessed into the corrugated material. The tops of the lining panels 4 are secured to the cup strip 2 by a clamping strip 22. The cap strip 2 serves as a handrail and is covered by a gripping member 13. The cap strip 2 also supports footway plates 15 which comprise a corrugated metal core (30) within a plastics sheet (31), the spaces being filled by a rigid foam (32), Fig. 5 (not shown). In a further embodiment, Fig.11 (not shown), the bars (44) and (45) are undercut and sealed by a sealing compound (47) e.g. silicone rubber. In another embodiment, Figs.6, 7 and 8 (not shown) the corner is filleted by an integral fillet (16), with grooves (23<SP>1</SP>) for the panels 4 and 5, or by a separate strip (36) and the bottom joints are covered by a strip (41). The seal is then effected by covering with a tape (34) whose edges only are adhesive, allowing the centre portion to flex and thus allow slight relative movement of the panels. Corners can be produced by bending the wall sections 1, Fig.13 (not shown). The handrail may be modified as in Fig.4 (not shown) to be made of steel (13<SP>1</SP>) or as in Fig.11 (not shown) to form a stretched-on cover (52).

Abstract: 457,307. Cycle &c. driving-mechanism. STAMATOWITSCH, M., 41, Siebachstrasse, Nippes, Cologne, Germany. April 20, 1936, No. 11250. [Class 136 (ii)] In driving-mechanism for bicycles and like vehicles and for other purposes, of the type in which the weight of the human body is utilized, the saddle or seat being connected to a driving- crank, the weight of the body is caused to act on the upper pivotal point of a quadrilateral frame of links, the expanding and contracting movements of which are transmitted from the upper pivotal point to the crank by a connecting- rod. In the bicycle shown, the frame comprises two immovable bars a, b, and a movable linkwork consisting of four pivoted links c, d, e, f, the saddle h being mounted on an extension of the link c, and footrests o on an extension of the link e, while the pivot between the links c, f is connected by a link g to the bar a. By movements of the rider's body, his weight is made to act alternately on the saddle hand footrests o, thus producing alternate contraction and expansion of the linkwork, the movements being transmitted by a connecting-rod r and crank s to a chain wheel k, which is mounted on the link e and drives the rear wheel through a chain m. In a modification, the linkwork is slightly modified, the link c being connected to an intermediate point on the link g, and the link e extended back beyond the wheel axle, and the drive is supplemented by pedal-crank mechanism, the crank s being extended to form one of the pedal cranks. The weight of the rider may be supplemented by an inanimate weight acting as an inertia device, and a flywheel and a small motor acting as an additional source of power may be provided.

Filed: 1941-09-03
Abstract: 551,704. Cheese. EVERY, C. E. (De-Raef Corporation). Sept. 3, 1941, No. 11282. [Class 84] Cheddar and other hard cheeses are manufactured by a method in which the milk is first Pasteurized and then neutralized by a basic substance, after which a lactic-acid producing starter is added and the milk is then coagulated by a suitable agent such as rennet. The curd is then cooked, cut, Cheddared, milled, salted, pressed and dressed. The growth of undesirable bacteria or micro-organisms is retarded by the preliminary Pasteurization and neutralisation of the milk, and thereafter a desired taste or flavour is produced in the milk by the known and selected bacteria in the starter which is then added so that uniformity of result is obtained. The neutralising agent may be calcium oxide or magnesium oxide. The starter is added to the extent of about 5 per cent. by weight of the milk, and is made from milk which has been neutralized, Pasteurized, and inoculated with a desirable lactic-acid producing organism.

Title: Improvements in and relating to adjustable thread tensioning devices
IPC: D03J5/24
Filed: 1927-04-28
Abstract: 288,442. Duncan, A. April 28, 1927. Tension arrangements. - In thread-tensioning devices for weft-winding and other purposes a ball is pressed against the end of a sleeve through which the thread &c. passes by the direct or indirect action of a spring carried by a bracket furnished with a screw device for adjusting the pressure. In one form, applied to a loom shuttle, the ball 12 is pressed against the sleeve by a spring 11 arranged in an axial pocket in a screw 9 in a bracket 5 which can be screwed into the shuttle. The sleeve 14 may be split at 20 to facilitate threading and be arranged within an outer casing 15 formed from a blank in a manner described and provided with a split 21 and a slot 16 leading to an eye 19. After the outer casing 15, which may be tapered, has been driven into the shuttle, the shuttle may be threaded by means of an incision 22 registering with the splits 20, 21, whereby the thread 4 may finally be drawn into the eye 19, and as this is out of register with the splits 20, 21, unthreading of the sleeve is prevented. The pressure of the spring 11 is adjusted by rotating the screw 9. The casing 15 has a spring tongue 18, and a steel or brass point may be provided on the side of the shuttle adjacent an aperture 7 to hold the tongue away from the wood of the shuttle. In a modified device, the ball is held between two sleeves, which are slotted for automatic threading. An adjustable bush, regulates the pressure of the spring employed. The bush may be secured in its adjusted position by a set screw. In another modification, the thread passes through three hollow sleeves holding two balls between them and in a further modification, several balls 53, Fig. 12, are held between sleeves 54 in a tubular casing 55 having a screwed annular washer 56 forming an abutment for a spring 57 acting on a shoulder'58 of the lowest sleeve, which has a hollow extension 59. A screw 60 acting on the uppermost sleeve can be turned to increase or decrease the pressure with which the balls and sleeves are held together and can be locked by a nut 61. The device is threaded by passing the thread right through all the sleeves by means of a hook. The thread may be introduced through any one of a number or transverse holes 62 and be brought out at any of these holes instead of through the bottom sleeve different tensions being' thus obtainable. Steel or other metal or glass balls may be used and the seats therefor may be of steel or other metal &c. or of enamelled porcelain. Yarns or threads of linen, cotton and wool &c. may be tensional by the device. The Provisional Specification refers to a spring push used for freeing a spring projection when threading the split sleeve.

Abstract: 1,137,091. Seals. LIPS N.V. 16 March, 1966 [17 March, 1965], No. 11435/66. Heading F2B. Means for sealingly transmitting pressure liquid between a non-rotary casing 2 and a passage 16, 17 in a rotary shaft, e.g. for transmitting pressure oil to and from the pitch varying mechanism of a variable pitch ship's propeller through the propeller shaft 1, comprises a non-rotary ring 18 having liquid passage means 20, 21 therein and mounted on the shaft for limited axial movement between two rings 6 and 8 rotatable with the shaft, the end faces of the ring 18 sealingly co-operating with radial faces on the rings 6 and 8 and means being provided to generate a liquid pressure hydrodynamically between the co-operating faces of the rings. The ring 6 is formed by a collar on the shaft and the ring 8, keyed to the shaft by a key 11, is slidably mounted on a backing ring 7 and urged by springs 14 towards the ring 18 a radial bore 20 in which is connected by a pipe 26 and pivotal union 27 with an oil supply pipe 28. An 0-ring 9 seals the ring 8 to the ring 7 which is secured to the shaft 1. Rotation of the ring 18 is prevented by a pin 19. Axial grooves 22 extend from circumferential groove 21 in the ring 18 to the end faces of the ring each of which has a flat annular part 23, surrounded by a groove 24 and an annular area 25 comprising spaced radially extending grooves 29, Fig. 3, and circumferentially inclined surfaces 30 which, when the shaft rotates, act to pressurize the oil present between them and the opposing faces of the rings 6 and 8. The ring 8 has grooves therein adjacent a shoulder 10 on the shaft and oil passing through these grooves acts on the back of the ring to augment the pressure of the springs 14 urging it towards the ring 18.

Title: An improved internal combustion engine with two pistons acted upon by the same impulse
IPC: F02B75/02
Filed: 1937-04-23
Abstract: 476,367. Two-stroke engines. RIS, A. April 23, 1937, No. 11626. Convention date, May 6, 1936. [Class 7 (ii)] In a valveless engine having two pistons acted upon by each impulse and controlling the cylinder inlet and exhaust ports, the auxiliary piston which controls the inlet port makes four unequal strokes, one of which is a driving stroke,. while the main piston which controls the exhaust port makes two strokes of equal magnitude, and the auxiliary piston at the dead centre point following the driving stroke does not expose the inlet port which is only exposed after the scavenging stroke during a succeeding stroke of greater amplitude. The crank-shaft 8 drives at twice its speed a shaft carrying a crank 15 on which is pivoted a connecting rod 14; the other end of the connecting rod 14 is pivoted to the free end 13 of a floating lever 12 carrying at its other end the auxiliary piston 7, the lever being fulcrumed about a crank 17 on a shaft driven at crank-shaft speed. In operation, as the main piston 6, plotted on the curve a, Fig. 1, descends from the position of Fig. 2, the auxiliary piston as shown by the curve b, descends rapidly to the point c in the cycle where ignition occurs. Both pistons drive the crank-shaft until the exhaust port 2 is opened by the main piston. The auxiliary piston now descends rapidly with a much longer stroke to expel the burnt charge at the point e in the cycle and, as the main piston rises, the auxiliary piston rises to its highest point at f to uncover the inlet port. The amplitude of the smaller stroke of the auxiliary piston is about half that of the stroke of the main piston.
