Title: Improvements in or relating to drilling machines
IPC: B28D5/02
Filed: 1943-11-29
Abstract: 582,763. Drilling diamonds. DEFENSE SUPPLIES CORPORATION. Nov. 29, 1943, No. 19943. Convention date, Oct. 12, 1942. [Class 83 (iii)] A diamond drilling-machine comprises a number of units secured to a vertical panel 11 with a flanged base 12, each unit having a vertical drill spindle 2 and an aligned work-holding rod 3 on which the diamond is carried, in the usual mounting provided for use in a wire-drawing machine. The rod 3 is counterbalanced by a thread 30, with a spring or like resilient member 48, to act as shock-absorber on impact of the diamond and drill-wire 1, and passing over a pulley 33 to suspend a container 35 for shot. The bar is held by the thread, due to its inclination, against spaced pairs of upper'and lower rollers 38 mounted on centre bearings on bracket 90 adjustable laterally in two directions at right angles by a nut and screw 100 and by screws 102 to secure parallelism to, and correct alignment with, the drill spindle. A rapid reciprocation of small amplitude is iinparted by an eccentric 42 on a shaft 43, belt-driven at 56 from a countershaft 58 that also drives the drill spindle at 21 and is driven at 24 from a pulley 25 on the motor shaft. The eccentric acts on a lever 40 pivoted on centres at 41 engaging screws in a block 60 vertically adjustable, to apply feed to the diamond holder, on rods supported in the base and in a bracket 62. One of the rods is threaded to provide for movement by a knob 65. The short end of the lever has pivoted to it an offset block 50 held in place by a leaf spring 52 and carrying an arm 45 acting on a pin on the rod 3 to depress it in opposition to the pull of the thread 30. In a modification, the eccentric 42 acts through a T-piece 73, Fig. 12, on a rock-shaft 74, that acts on the lever 40 mounted to swing in a horizontal plane and having at its shorter end a screw 79 that presses against a normally flexed spring 80 having a pad 83 of leather or rubber &c. that presses against the rod to move it downwards. The spindle is mounted in upper and lower ball bearings contained in housings 104 separated by a cylindrical shell 116 having an opening for the belt and carrying a brake pad adjusted by a screw 120 to regulate the spindle speed. A second brake pad, carried by a rod 124 that can be pressed in against a spring, provides for stopping the spindle when required. Oil supplied from a container 110 screwed into the upper housing 104 passes through the bearing and is thrown by a collar to a recess drained by a port connected at 105 to the lower bearing which is similarly lubricated and delivers to a pipe 108 leading to a filter 109. The action of the drill wire may be observed by a microscope 128, Fig. 14, mounted in a frame 129 having a member 136 carrying depending'rods 137 that can be received in holes in a bar 140 adjustably supported in the lower housing 104. The frame 129 is supported further by a rod 131 engaging a recess in the top of an adjusting screw 133. The microscope can be shifted as required from one drill unit to another.
Patent GB-583292-A (GB)
Title: Improvements in the production of protein filaments and of yarns produced therefrom
IPC: D01F4/00
Filed: 1944-10-16
Abstract: <PICT:0583292/IV/1> A continuous multi-filament protein yarn is obtained by extruding a solution of protein into a coagulating bath, immediately, or after passage through a plasticising bath, conducting a plurality of the resulting filaments in collective thread formation through a duct in which the filaments are subjected to the influence of one or more jets of dry air or other gas in such manner that the filaments are separated by the action of the jets and individually dried, re-collecting the dried filaments and subsequently spinning them collectively as a single yarn.  Preferably, the air jets are directed similarly to the direction of travel of the yarn through the drying duct.  The air is preferably heated.  Lactic casein dissolved in borax solution may be used for the spinning solution and a concentrated solution of common salt containing acetic, formic or other organic acid and aluminium sulphate may be used as the coagulating liquid.  As shown in Fig. 1, the spinning solution is extruded through a nozzle 12 which is immersed in a coagulation bath 14.  The bundle of filaments 15 is drawn off by the rotating godet-wheel 17 and delivered to the upper end of a vertical duct 18. Hot air is injected through branch ducts 181 and caused to travel down the duct 18.  The air current causes the filaments to separate from each other whilst they are being dried and any tendency for them to coalesce is avoided.  On emerging from the duct, the yarn is spun into cake form in the rotating pot 19.  The godet-wheel 17 may be driven at such a rate as to cause the filaments to be stretched.

Title: Improvements in pneumatic power hammers
IPC: B21J7/24
Filed: 1921-08-02
Abstract: 188,069. Massey, Ltd., B. & S., and Massey, H. F. Aug. 2, 1921. Power hammers.-A pneumatic power hammer of the pump piston type has a valve which in one position causes the pump to compress air into a reservoir for the purpose of striking single blows or holding down. The valve f preferably comprises a series of pistons 5- - - - 13, Fig. 1, on a spindle 4 by which it is moved within cylinders m, n having ports o, p - - - w connected to the ends of the hammer and pump cylinders a, c, a reservoir l, and the atmosphere. The pistons 5, 12 have radial ports 15, 16 from a common central passage 14 which is connected to the reservoir by holes 17. The pistons 6, 12 have holes from the upper to the lower face and the pistons 8, 10 each have ports from an annular cavity to the circumference and to both faces, that to each inner face being covered by a non- return valve 18, 19. When the valve f is in the position F, W as shown in Fig. 1, the upper and lower ends of the cylinders a, c are connected through ports p, q and v, u and a succession of powerful blows is delivered. As the valve is moved to the position N W the strength of the blows decreases until the ports v, p are closed, and the pump is short circuited through ports q, r, t, u and the reservoir l. In the top position H U air from each end of the cylinder c, which has the usual valves or ports, will be forced in turn through the non-return valves into the reservoir l which is at the same time connected through ports 17, 14, 16, v to the lower end of the cylinder a, the upper end being exhausted through inclined ports 15 so that the hammer is held up. In the position H D the pump still supplies the reservoir but this is connected to the upper end of the cylinder a through ports 17, 14, 15, o the lower end being exhausted through ports v, 12 and w so that a. single blow is struck and the hammer is held down until the valve is again moved. In a modification there are separate reservoirs for holding up and striking blows and in another a reservoir is supplied from one end of the pump only and is only used to strike, the other end of the pump being always connected with a clearance 45, Fig. 2, except in the F W position, when cylinder ends are connected through ports 23, 37, 21 and 26, 42, 27. In the N W position the cylinder c is short circuited through ports 25, 40, 24 and the clearance 45. In the H U position air is forced through ports 24, 38, valve 18, and ports 37, 22 into the reservoir l while some air is forced through the valve 19 into the lower end of the cylinder a and the upper end is exhausted. In the position H D the lower end is exhausted through ports 28 and the upper end opened to the reservoir through ports 22, 21. In another modification the valves 18, 19 are separate from the valve f.
