Title: Improvements relating to rotary pumps and engines
IPC: F04C2/336
Filed: 1948-06-24
Abstract: 646,407. Rotary pumps and engines. ORR, H. C. H. June 24, 1948, No. 17005. [Class 110(ii)] A rotor F, on a shaft G, is coupled to an outer eccentric rotor D by means of vanes H which pivot in the outer rotor and pivot and slide in cylindrical parts J carried by the rotor. End plates E are secured to the rotor D by screws E<SP>1</SP>, and four pins E<SP>2</SP> extend betweent the plates E, passing through holes F', to transmit the drive from the inner to the outer rotor. At any moment, at least one of the pins is exerting a driving force on the outer rotor, the holes F' being large enough to allow for the relative eccentric movements of the rotor. Each end plate E has a central hole E<SP>3</SP> to allow for eccentric movement relative to the shaft G. A stationary valve plate C contains curved ports C<SP>1</SP>, C<SP>2</SP> which allow communication between inlet and outlet ports in the body A and curved ports E<SP>4</SP> in the rear plate E leading to the working spaces between the vanes H. In a pump, for most of a revolution, two rotor ports 1 communicate with the stator delivery port C' and two with the delivery port C<SP>2</SP>. Relief ports E<SP>5</SP> allow outflow of liquid from a slot during the inward movement of a vane, to prevent fluid trapping. Ports C<SP>3</SP> and C<SP>4</SP>, in the plate C, communicate respectively with the delivery and suction sides of the pump so that the left-hand vane, Fig. 3, has pressure on both of its faces, the right-hand vane has suction on both its faces and the top and bottom vanes have pressure on one face, and suction on the other. The pump unit may be detached from the body by removing screws B<SP>2</SP>. The inlet and delivery pipe sockets are above the level of the working ports of the pump so that, when stopped, the pump remains full of liquid and needs no priming. Drain plugs K are provided. The pump may be reversed in direction, the valve plate C being removed and turned through 180 degrees. Wear may be allowed for by insertion of packing between the plate C and the body A, or fitting a thicker valve plate. Parts of the pump may be made of plastic material.

Abstract: 562,036. Making wire articles. FRASER, H. A., and CRIGHTON, P. F. Dec. 9, 1942, No. 17546. [Class 83 (iv)] Angular bending.-A loop is formed in a taut wire by bending it by means of members which move in the plane of the wire without relative slip during bending. In a machine for forming a number of elongated loops l, Fig. 41, in a wire and cutting off a formed length to be interlaced with other lengths l<1> to form a mattress, the wire w, Fig. 12, is tensioned by rollers 142, guided by rollers 143 and gripped between a horned bender 2, carried by a shaft 24 and a bed 6 pressed towards it by a roller 65 and lever 64. The bed 6, bender 2 and fork 9 are then moved to the left over a bender 1 and clamp 5, thus drawing, the wire through the rollers 142. The bender 1 is then oscillated clockwise about the axis of its shaft 16, as shown in Fig. 15, and, with the clamp 5 is raised into the plane of the wire. The bender 1 is then oscillated back again to bend the wire about the horn 8 and press it against the clamp 5. The bed 6 is then withdrawn and the bender 2. is raised out of the plane of the wire, oscillated into the position shown in Fig. 17, moved, with the bed 6, in a reverse direction and returned to the plane of the wire. The bender 2'is then oscillated back again to bend the wire about the bender 1 and horn 7 and the bed 6 is moved to clamp the wire against the horns 7, 8, as shown in Fig. 12. The fork 9 is then advanced to engage the loop, the bender 1 and clamp 5 are moved down out of the plane of the wire, and the cycle of operations repeated until the desired number of loops have. been made. The formed loops are moved to the left with the bender 2 by one-way catches on a bar 106 engaged by a projection 109 on the bender and they pass between guides 89, 96, this being pressed towards the loops, while stationary, to hold them firmly while a blade 88 acts on the portion 149, Fig. 41, to offset it. All these movements are effected by cams on a driven shaft and a snail cam thereon rotates a pinwheel on the shaft 120, Fig. 12, whereby, when the desired number of loops has been formed, a cam 122 acts, through levers 124, 128 and abutment 117, to cause the lever 85, which operates the blade 88, also to operate a cutter 114 to cut off the formed length required and forks 130, one only being shown, to transfer it to collecting rails below.
