Abstract: 588,509. Washing-machines. CONSTANTINE, W. W. (General Motors Corporation). Feb. 24, 1945, No. 4673. [Class 138 (ii)] A washing machine comprises a tub having filtering means below its overflow level and an agitator for the clothes and water arranged to circulate the water through the filtering means. As shown, the tub consists of outer and inner walls 10, 11 riveted together at 13, the space 12 between the walls being open between the rivets to allow free flow of liquid. The verticallyreciprocable agitator 14 carries at its lower end a rubber or like conical member 16 which, during the agitating operation, facilitates toroidal circulation of the liquid as indicated by the arrows 17, part of the liquid following a path 18 through perforations 19 in the tub wall 11, upwardly through space 12 and then inwardly through filtering screens 20 on the wall 11 on which scum accumulates. On subsequent rotation of the tub, outward centrifugal flow of liquid occurs through the perforations 19 and screens 20, the water flowing over the lip 29 on the tub wall 10 carrying the scum with it. The filters may be further cleaned by brushing or by washing them separately after removing them from clamps 21 by which they are secured to the wall 11. Alternatively, one continuous filter may be provided around the wall 11. The tub is mounted on a rubber-like collar 22 which supports rotatable and vertically-reciprocable shafts 23, 24 respectively, shaft 23 being secured to the tub by a hub 25 and shaft 24 secured to the agitator by a nut and bolt device 26. Preferably shaft 24 is vertically-keyed with the rotatable shaft 23 so that it reciprocates independently of but rotates with the shaft 23.

Patent GB-274374-A (GB)
Title: Improvements in and relating to automatic valve mechanism for liquid meters
IPC: B67D7/16
Filed: 1927-02-23
Abstract: 274,374. Hurlbrink, E. Feb. 23, 1927. Liquid meters. - In a liquid meter having one or two measuring chambers, the valve is operated by a spring stressed bv the action of the liquid on a plunger, and released after the liquid has ceased to act on the plunger, the interval between the completion of filling of a chamber and the actuation of the valve allowing bubbles to escape. Where two measuring chambers are employed, means are provided to make the action dependent on the complete emptying of the chambers alternately. A pipe 31, Fig. 2, which may be of small bore or have a throttling member, leads from the supply pipe 30 to a cylinder 55; when a measuring chamber is filled, the pressure moves a piston 34 to compress a spring 35, a nut 38 carried by the piston rotating on a thread 37 on the spindle of the valve 1. At the end of the stroke, a member 57 disengages a pawl 58 from a valve 32, and the latter is moved by a spring 56 to close the inlet pipe 31 and open the exhaust pipe 60. The spring 35 then returns the piston 34; during this movement, the nut 38 is prevented from rotation by a pawl and ratchet and the valve 1 is consequently operated. Additional means for locking the valve 32 in its retracted position comprise a rod 72 connected to a lever 71 having a float 69 disposed in a chamber connected to the outlet pipe of the meter, so that the valve 1 cannot be operated until after the complete emptying of a measuring chamber. In a modification, the pipe 31 is connected to the cylinder 55 under the control of a balanced valve 103, Fig. 6, acted on by a spring 104 and a float lever 109. In a further form, a balance weight 120, Fig. 7, loosely mounted on the spindle of the valve 1 has a pawl 122 cooperating with a ratchet wheel 117 fast on the spindle, and is connected to pistons 125, 126 acted on by springs, the supply and exhaust of liquid being controlled by a valve 134, locked in the position shown by a member 146, which may be disengaged by a projection 142 on a rod 143.

IPC: F42B14/06
Filed: 1918-03-28
Abstract: 131,034. Thring, L. G. P. March 28, 1918. Projectiles.-Relates to sub-calibre projectiles, and consists in providing a carrier in the form of a sleeve or collar divided longitudinally into two or more parts and having internal annular ribs engaging corresponding grooves in the projectile, the rear wall of the grooves being inclined. Immediately ton leaving the gun, the carrier drops away from the projectile. In the construction shown, the carrier is divided into three parts and is formed with two guiding-flanges F, G, the rear one of which is perforated so that the gas pressure acts mainly on the front flange. Small spaces E, which are left between the ribs on the carrier and , the projectile, prevent the carrier from acthering to the projectile, and the entry of the gases into these recesses assists the stripping of the carrier from the projectile. The parts of the carrier are held together by the cartridge case or by a binding-material which will readily be fired and disintegrated while the projectile is in the gun. The projectile may have a rear part or tail shaped in various ways.
