Title: Improvements in ladies' work cabinets or companions
IPC: A47B29/00
Filed: 1919-06-02
Abstract: 150,086. Dupont, G. C. June 2, 1919. Work-companions.-A work companion or cabinet comprises columns d mounted on a stand a and carrying reel cradles d<1> pivoted in the sides of the columns so that they can be pulled outwards for the purpose of placing or removing reels therein; the cradles are held in the normal position by light spring or elastic bands g<1>. The cotton &c. from each reel is drawn through a slit d' in the cradle and over a thread-holding and cutting device consisting of a fixed member f having its upper end slightly bent outwards and a hinged cutting-member f<1> having an incision or cleft in the lower end thereof; when the thread is pulled for the purpose of cutting it. it becomes jammed between the parts f, f<1>. The stand a is fitted with drawers or pivoted trays c, c<1> for holding scissors, needles, &c. A central hollow handle g is provided with a removable cap g<1> and contains knitting-needles. A cage consisting of wooden disks having central holes and fixed between three vertical rods forms a holder for balls of sylko &c., and is slid over the handle g; thread-guides and thread-holding and cutting devices as described above are provided on the vertical rods. A modified form of column for the reels, which can also be used as a separate article, comprises four carrier uprights fixed to a base supporting a disk carrying a central vertical rod upon which the reels are slid. Disks having inwardly-projecting tongues engaging a groove in the rod are arranged between the reels, so that the unwinding of the thread from one reel will not cause the other reels to rotate. The threads are drawn from the reels through horizontal slits in one of the corner uprights to the thread-holding and cutting devices; the upper end of the column is provided with a small detachable pin-cushion. The columns are removably fixed to the stand a by screws and nuts or by sliding the Lases thereof into grooves in the stand. Either form of coliiiiiu may be arranged on a board adapted to be hung on a wall, cupboards being provided at the sides of the board for scissors etc.; a receptacle in the form of a shell for buttons &c. is provided underneath the column and a pin-cushion is fixed at the top ou either side of the column. The stand (t is provided with receptacles k for pins &c.

Title: Small tractor
IPC: B60K17/34
Filed: 1932-05-14
Abstract: 387,561. Tractors. WEBER, A. and WEBER, L., Bad Kreuznach, Lohrermuhle, Germany. May 14, 1932, No. 13943. Convention date, May 23, 1931. [Classes 79 (i), 79 (ii), 79 (iv), and 79 (v).] In a tractor having the front axle 5 steered and driven the hollow steering pivot 23 of the axle and a driving shaft 18 enclosed therein are arranged out of the central vertical longitudinal plane of the tractor toward that side which, due to the gearing 19, 20 driving the front axle, tends to move ahead when the tractor is being driven forwardly. The wheel which is nearer the steering pivot thus carries a heavier load which neutralizes the tendency to move ahead. In the construction shown the steering pivot 23 is displaced towards the " off " side by an amount a, and is also inclined away from the vertical by an angle alpha. The tractor is provided with a tubular frame 1 also displaced laterally from the centre line and having a rear axle casing 21 and a front casing 24 enclosing the steering pivot 23 which is secured to the front axle casing 22. The engine 2 and gear box 3 are mounted on the frame 1 and drive a differential gear 12 the shafts 6, 15 of which drive the rear and front axles respectively through bevel gearing. The front axle is steered from the hand-wheel 27 through a shaft 30, bevel gear 31, chain gear 35, and worm gear 26, 25.

Title: Improvements in or relating to towed gliders
Inventor: CARLSON RUSSELL MANSFIELD
IPC: B64D3/00
Filed: 1952-06-03
Abstract: 727,809. Towing aircraft. CHANCE VOUGHT AIRCRAFT, Inc. June 3, 1952 No. 14042/52. Class 4. A tow release mechanism for a glider is operable by a ground engaging member on touch down, which mechanism then returns to position, whilst the ground engaging member is returned to its operable position only when a predetermined airspeed is reached. In Fig. 1, the glider 10 is towed by a bridle 50 releasably fastened to bridle posts 38, and is provided with a nose skid 34. Referring to Fig. 4, on touch down the skid 34 is raised relatively to the glider, together with the oleo-strut 88, connected by a radius link to pivot 76. In the fully raised position, the roller 90 on the strut 88 abuts the projection 124, and is retained in that position by stop 116. In being raised, it has carried with it the one-way catch 77, thus tilting frame 74 about pivot 76 and pulling cable 72. The catch 77 then slides off face 114 of cam 112, returning the frame and cable to their normal position. When the airspeed reaches a predetermined value, the vane 118 releases roller 90 from stop 116, and under the action of gravity, skid 34 and strut 88 fall, cam 112 deflecting frame 77, and the device becomes operative on touch down. Fig. 6 shows the end of a bridle post, 50 being one arm of the bridle, and 52 a plate bored at 56 to take pin 60, controlled by cable 72 and spring 64 to release or retain plate 52. Means are described whereby the glider may be made to fly offset from the towing aircraft, comprising deflectable surfaces and means off-setting the towing bridle, and operable by vane 118 to centre the bridle for touchdown.

Abstract: 360,442. Glass manufacture. RANKIN, C. H. and RANKIN AUTOMATIC GLASS FEEDER CO., Ltd., Fishergate, York. May 7, 1930, No. 14076. [Class 56.] Gathering molten metal.-A device for supplying molten glass to a machine that gathers charges by suction comprises a trough supported on a carriage which can be moved between the machine and a tank furnace, and means for lifting and lowering the trough relatively to the carriage. The trough 1 is mounted on the piston rod 3 of a cylinder 4 which can be operated by fluid pressure, and a device may be provided to actuate the cylinder from time to time whereby the trough can be raised or lowered in synchronism with the movement of the head 6 of a rotary glasswareforming machine. The cylinder 4 is supported by a carriage 7 movable on rails 8 by means of the piston rod 9 of a fluid-pressure cylinder 10. In one position, the trough is drawn into a heating-chamber 11 arranged below an outlet orifice 12 in the floor of a forehearth 14 of a tank furnace. The supply of glass to the trough is controlled by a plug 15, and may be continuous or intermittent as desired. The heating chamber 11 may be mounted on a wheeled truck 17 to enable it to be moved from place to place. A water-cooled skimmer 18 can be lowered by fluid-pressure cylinders so as to skim the surface of the glass as the trough is drawn out of the chamber 11. In use, the trough is filled with molten glass while in the chamber 11 and is moved out to the forming-machine. It is then raised so that the mouth of the mould 6 becomes immersed in the glass and gathers a charge by suction. After the mould is filled, the trough is lowered and the mould is replaced by another.

Title: Improved process of and means for manufacturing chloride of lime
IPC: C01B11/06
Filed: 1928-05-15
Abstract: 317,716. Carughi, A., and Paoloni, C. May 15, 1928. Chloride of lime, averaging more than 40 per cent available chlorine is manufactured by chlorinating slaked lime suspended and ground in an inert liquor, e.g. carbon tetrachloride, which does not dissolve either lime or chloride of lime. By keeping the temperature during the reaction above, 40‹ C., and then suddenly cooling to below 20‹ C., at the end of the reaction the chloride of lime becomes crystalline, and is more stable, dissolves readily in water and may be compressed. The complete process is carried out in the apparatus shown. B is a jacketted rotary drum, with hot and cold water circulation, fitted with heavy balls, which act like. a pebble mill. The slaked lime and inert liquid are introduced through the aperture 11. Chlorine gas is introduced through a pipe A and the drum rotated. Any air in the chlorine is released through a pipe C and deposits any carbon tetrachloride it may carry in the condenser F and absorption vessel G. When the reaction is complete the temperature is rapidly reduced below 20‹ C. A vacuum is then applied to the whole apparatus, and the chloride of lime freed from the liquid by vacuum distillation, the liquid being recovered in vessels F and G. The dry chloride of lime is then automatically discharged. In a modified apparatus, each stage is carried out in a separate appliance.
