Title: Machine for Grinding the Rims of Glass Vessels.
Inventor: MATHY MAURICE
IPC: B24B9/12
Filed: 1919-02-17
Abstract: 126,596. Mathy, M. Feb. 17, 1919. Disk apparatus; supplying fluids.-Consists of apparatus for grinding the rims of glass vessels. The grinding- disk 2 is mounted on a vertical shaft 1 driven by a belt and pulley 7 from an electric motor 6. The shaft slides freely in a bearing 3 and rests by means of a shoulder upon a sleeve 5 slidably mounted in a socket 8, the sliding parts being counterbalanced by a weight 12. The disk is brought into contact with the glass vessel by means of an adjustable weight 42, carried by a lever 11 mounted on the spindle of a cog-wheel 10 gearing with a rack 9 upon the sliding sleeve 5. A ring 19, adjustably secured to the sleeve, limits the downward movement. The shaft 1 has an axial duct 15, through which water is supplied from a hose 16 to the grinding-surface. In an alternative form, the axial movement of the grinding-shaft is obtained by means of a weighted lever and a sliding sleeve without the use of rack-andpinion gear, the weight of the moving parts in this case being counterbalanced by a spring. In either form, water may be supplied through a duct 35, Fig. 3, rotatably mounted upon the diskcarrier 37, which is bored at 39, 40 to allow passage to the centre of the disk. Side pipes 44 also conduct some of the water to adjustable pipes 45, by means of which it can be directed against any desired point on the grinding-surface.

Title: Improvements in motor-ploughs
IPC: A01B63/06
Filed: 1919-02-18
Abstract: 139,286. Pedersen, H. Feb. 18, 1919. Ploughs.-To raise and lower the tools of a motor-plough, the power shaft 5 has splined to it, at the farther side of the variable-speed gearbnx 4, a sliding clutch member 15 which can be moved longitudinally to engage corresponding clutch surfaces on sleeve members 13, 14 adapted to drive, directly and through an intermediate pinion respectively, gear-wheels 19, 21 on the lifting and lowering shaft 18. The shaft 18 causes the lifting and lowering of the implements by driving a pinion which engages a rack on the standard of the rear wheel of the plough. To ensure the clutch being alternately thrown in on the raising and lowering sides, the shaft 18 drives, through a worm-gear 31, 32, a vertical spindle 33 provided with a screw thread on which a non- rotata,ble nut 34 travels. This nut slides along a vertical rod 35 pivoted at one end to a link 36 loosely carried by the shaft 18, and at the other to an arm 37 rigidly secured to a rod 28. The rod 28 is adapted to be rotated by the operator to turn a quick-threaded screw 29 on which a nut carrying a fork operating the clutch member 15 moves. If the nut 34 is in the position shown in dotted lines in Fig. 4 on throwing in the clutch 15, the shaft 18 is driven, rotating the spindle 33 and causing the nut 34 to travel downwards until it engages the arm 37 and automatically turns the shaft 28, thus causing the clutch 15 to be disengaged. The arm 37 then prevents the clutch from being thrown in on the same side as before, and, if thrown in on the opposite side, the shaft 18 is driven in the opposite direction, the nut 34 moving upwards along the spindle until it engages an adjustable abutment secured to the rod 35. The rod and arm 37 are thus automatically moved and the clutch thrown out as before. An indicator operated by the nut 34 shows the depth of working of the ploughs.

Title: Improvements relating to apparatus for transferring loads to aircraft in flight
IPC: B64D1/22
Filed: 1931-02-11
Abstract: 370,563. Transferring articles to conveyances in motion. WHITE, A. E., 5, Quality Court, Chancery Lane, London.- (Aero Pickup Service Corporation ; 940, Old South Building, Boston, U.S.A.) Feb. 11, 1931, No. 4242. [Class 103 (iii).] Relates to apparatus for transferring food, petrol, &c. supplies to an aircraft in flight and of the kind in which a grapnel depending from the aircraft is adapted to engage a loop attached to the load and in which undue shock due to the inertia of the load is prevented by imparting to the latter an initial velocity in the direction of flight. According to the invention the flexible loop is extended between a pair of standards which are adapted to rock under the pull of the aircraft upon the loop and thereby to release a catch normally holding a carriage for the load against movement. In the construction shown a latch 40, Fig. 3, is released by the engagement of the grapnel with the loop 70, Fig. 2, and allows the carriage 9 to be propelled along a pair of slightly inclined rails 8 by means of a tensioned elastic member 51 that passes over a pulley 46 and has its ends attached respectively to an eye 52 on the carriage and to a drum 50 which can be set initially to regulate the tension in the cord 51 and consequently the final velocity of the carriage 9. A buffering device 17 brings the carriage to rest at the upper end of the rails 8. The loop 70 is supported in an elevated position by means of a pair of substantially vertical arms 27 mounted on rotatable horizontal arms 24 which in turn are supported and journalled in the upturned ends 23 of telescopic transverse arms 20, 22 secured to a pair of lower rails 7. The sets of rails 7, 8 and connecting members 14, 15, 16 therebetween constitute a framework suitable for mounting, e.g. by uprights 6, on a motor-car or like mobile support. The latch 40 is in the form of a double-armed lever pivoted at 41, the upper arm engaging a hook 42 on the carriage 9, and the lower arm or latch being associated with a bell-crank lever 43, link 45 and a slide 28 having an upturned end 29 engaged by cams 30 on the rotatable arms 24. When the grapnel engages the loop 70, the arms 27 are swung rearwardly rotating the arms 24 and cams 30, and thus retracting the slide 28 and link 45 against the action of a return spring 63; the double-armed lever 40 is therebv released and allows the carriage 9 to be propelled as required.

Title: Improvements in or relating to spring forks for motor cycles and the like
IPC: B62K25/08
Filed: 1945-03-08
Abstract: 579,900. Motor-cycle forks. BIRMINGHAM SMALL ARMS CO., Ltd., PERKINS, H., and PERRIGO, A. E. March 8, 1945, No. 4460/44. [Class 136 (iii)] [Also in Group XXXII] A telescopic front fork comprises a fluid seal 17 on the lower end portion of an upper tubular member 1, a tube 25 movable with a lower tubular member 13 and having a series of ports 33 arranged normally above and below the fluid seal 17 to allow passage of fluid between the tubular members 1, 13, the construction of the fluid seal 17 being such as to prevent direct fluid flow from the member 13 to the member 1 on compression of the fork, but to allow direct fluid flow between them on extension of the fork. The fluid seal consists of a bush 17 having clearances 27 which are closed by a valve 19 under pressure of the fluid during compression of the fork. The damping is progressive since the number of ports 33 within the member 25 diminishes proportionally with compression. A piston 29 fixed to the tube 25 serves to expel fluid from the tube 1 on extension of the fork. During this action part of the fluid passes directly through the valve 19 and part through the holes 33, the damping thus being partly progressive. A spring 31 limits the recoil and a further spring (not shown) is mounted between a gland 21 and the lower of the two points at which the fork is secured to the steering head. The wheel axle is mounted in a lug 15. Specification 571,486 is referred to in connection with the construction of the gland 21.
