Title: Improvements in or relating to machine tool arrangements such as centerless grinding machines
IPC: B24B5/18
Filed: 1931-03-13
Abstract: 363,912. Hydraulic transmission of power. CINCINNATI GRINDERS, Inc., 3058, South Street, Cincinnati, Ohio, U.S.A. -(Assignees of Booth, C.; 3058, South Street, Cincinnati, Ohio, U.S.A.) March 13, 1931, No. 7777. Convention date, March 19, 1930. [Class 69 (ii).] In a centreless grinding or other machine, the tool operating upon a workpiece is mounted on a slide associated with an hydraulically operated screw to move the tool rapidly to working position and then slowly during work reducing. A grinding wheel 16 with trueing device 23 is mounted on a bed 15. A regulating wheel 18 is mounted on a slide 20 adjustable on a lower slide 21 carrying a work supporting blade 26. In initially setting up the machine rotation of a hand-wheel 27a, through gears 30, 34, shaft 36, gears 39, 40, and nut 41 engaging a screw feed 47 moves the regulating wheel relatively to the bed 15. To effect a slow adjustment to take up wheel wear a locking plunger 44 on a crank 43 is disengaged from the hand-wheel 27a and the crank is rotated to move stub shaft 32, pinion 31, gears 30, 33, 34, shaft 36, gears 39, 40 and nut 41. The nut 41 is secured to the housing 19 and the feed screw 47 is mounted on the bed 15. Automatic hydraulic mechanism for actuating slide. Actuation of a handle 77 shifts a valve 66 on rod 72 controlling the flow of liquid in a cylinder 57 with piston 56 racked to engage a gear 54 on a shaft 53 driving the screw 47 at a rate to effect rapid movement of the regulating wheel towards the grinding wheel. The speed is then reduced to normal work-feeding rate by a head 59 on a supplementary slide rod 60 engaging a member 61 on the piston 56 whereby the rod 60 is moved and engages a lever 75 to move the valve rod 72. The end of the rod 72 closes port 71 and the exhaust passes through port 86 throttled by a needle valve. The piston 56 continues its movement until the end engages an adjustable stop 94 which actuates the lever 77 to shift the valve 66 to retract the piston. Manual operation of the lever 77 then retracts the regulating wheel.

Title: Improvements in pipe couplings
Inventor: PEARSON KENNETH WHITE
IPC: F16L37/34
Filed: 1957-03-22
Abstract: 898,955. Pipe couplings. EXACTOR Ltd. June 23, 1958 [March 22, 1957], No. 7808/57. Class 99(1). In a pipe coupling comprising end fittings 1, 15 connected to fluid carrying pipes and equipped with valves 8, 22 which are loaded to close automatically as the fittings are separated and which are opened simultaneoulsy as the fittings are engaged, the valves are formed with areas which are so proportioned and disposed that the fluid pressure acting on them produces a closing bias on the valves when the fittings are not coupled and that the forces exerted by the fluid on the valves are balanced out when the valves are unseated as the fittings are engaged whereby the opening of the valves is completed independently of the fluid pressure. As shown, the fitting 1 consists of a hollow barrel 2 having a spider 3 on which is mounted a flanged disc 5 formed with a conical valve seat 7 for engagement with the coned end 9 of the spring- loaded ring valve 8. The fitting 15 comprises a barrel 16 having a coaxial cup-shaped inner component 17 in which the spring-loaded ring valve 22 slides and which is vented to the atmosphere by a bleed hole 17<SP>1</SP>. The fluid flow space 18 is blanked off by a flange 19 secured to the barrel 16 and formed with a conical valve seat 20 for engagement with the coned end 21 of the vale 22. A resilient sealing ring 35<SP>1 </SP>is provided in a tapered groove in each valve seat. Alternatively, one of the conical surfaces of each pair of valve and valve seat is formed with a resilient tongue which seals the valve and is distorted to allow metalto-metal contact between the valve and its seat. For opening the valves, the end fittings are drawn together by rotating a handwheel 39 fixed to a sleeve 26 which is rotatably mounted on the barrel 2 and. is in camming engagement with the flange 19 so that the valves 8, 22 are simultaneously displaced by the disc 5 and the flange 19 respectively. In a modification, the disc 5 is sucured by a tie rod to a support connected to the fitting 1 by a pair of webs. Similarly the inner component 17 is integrally connected to the fitting 15 by a pair of webs. The sleeve for drawing the fittings together bears against a thrust roller bearing mounted on the fitting 1 and is in camming engagement directly in the fitting 15.

IPC: B41F9/01
Filed: 1922-03-18
Abstract: 184,128. Johnston, T. R. March 18, 1922. Rotary offset machines.-Webs of fabric are printed on one or both sides with a continuous design by means of intagliated copper cylinders, or by thin intagliated plates secured to cylinders, co-operating with rubber offset cylinders of a diameter equal to or an exact multiple of that of the design cylinder. The offset cylinders press the web against a separate impression cylinder, or against a second offset cylinder when two sides of the fabric are being printed at once, as is shown in Fig. 1. In this machine, a design in three colours is printed on each side of the web g' by means of rubber-covered offset cylinders d<1> - - d<6> which receive the designs from copper cylinders a<1>, b<1>, c<1>, and a<2>, b<2>, c<2>, having the designs engraved in intaglio and provided with ink rollers e<1> - - e<6> and scrapers f<1> - - f<6>. The designs in the cylinders a<1>, b<1>, c<1> are the reverse of those in the cylinders a<2>, b<2>, c<2>, and the designs printed are continuous. In a modification, the offset cylinders d<1>, d<3>, d' print in coaction with a large impression cylinder, and the web is then led to a second large impression cylinder with which offset cylinders such as d<2>, d<4>, d<6> coact, electrical or other drying means being used for the impressions. In another modification, Fig. 3, engraved plates which may be reproduced by three-colour processes, or by the aid of lithography, are secured to cylinders a<1>, b<1>, c<1>; a', b', c<2>, and the gaps between the plates filled in as described in Specification 117,888. These cylinders print on offset cylinders d<1> - - d<6>, two cylinders being required for each colour. The offset cylinders for each colour may receive a design of exactly half its circumference, so that the two offset cylinders of each colour print a complete continuous design between them, or these partial designs may overlap each other. In a further modification, especially adapted for printing table cloths, flags, &c., offset cylinders such as d', d<2>, d' may print designs in one or more colours with an unprinted interval between the designs. In some cases, the web is wound up after being printed on one side, and the other side of the web is printed in the same machine by changing the printing rollers and printing on the plain side of the wound web by a separate operation.

Filed: 1926-03-22
Abstract: 272,993. Wagener, C., and Excelsior Feuerl÷schgerate Akt.-Ges. March 22, 1926. Fire-extinguishing by foam.-A method of extinguishing fires consists in mixing a liquid con. taining foam-generating substances &c. with air as by means of an open water-jet air pump, an injector, or the like. A pipe b, Fig. 1, attached to a water main enters a closable tank a containing a solution of a foam generator. From the bottom of the tank a pipe c leads to a known jet air pump d, open to the air at e. An outlet branch f discharges the foam either by hose pipe &c. or direct, to the fire. In a modification. Fig. 2, a cylindrical receptacle h contains foam generator in powder form, soluble in a water stream from pipe i. In a further modification, Fig. 3, the jet pump d is directly connected with a water main by a pipe l and foam, e.g, saponin in form of a powder or concentrated solution, flows from a receptacle m with the suction jet, under pressure if necessary. In a still further modification, Fig. 4, a foam generator is conveyed from the receptacle, m to the suction jet in a stream of air through the pipe e. In all cases, suitable chemical substances may be added to the solution of foam generator or powder. Where an open receptacle m, Figs. 3 and 4 is used. continuous operation is possible. In the cases of Figs. 1 and 2, two receptacles a and h may be used in parallel. In all cases, the effect of the jet air pump may be increased by using a baffle or distributor at the outlet thereby reducing large foam bubbles. 'The foam may be led into a wide foam conveying tube an open gutter, or directly to the seat of the fire.

Title: Improvements in and relating to power lift mechanism for plows and like agriculturalimplements
IPC: A01B63/28
Filed: 1924-03-31
Abstract: 224,153. Jensen, C. A., (Oliver Chilled Plow Works). March 31, 1924. Lifting-devices, power.-In lifting-mechanism in which the power is derived from the rotation of a supporting-wheel through a clutch and an oscillating lifting-disc loosely mounted on the axle and linked to the frame of the implement, the clutch comprises a spring-controlled rollercarrying arm carried by the disc and arranged to co-operate with an internally-corrugated member carried by the wheel, the roller being thrown into engagement with the corrugated member by mechanism operated by a control lever. The cranked axles of the land and furrow wheels are mounted in bearing brackets 4 on the frame 1. The internally corrugated or recessed wheel 11 is on the hub box of the land wheel and a flanged disc or housing 13 is rigidly fixed to the landwheel axle 7. The lifting-disc 16 has a peripheral flange encircling the housing 13 and is linked to the frame 1 by a curved lifting-arm 20. Pivoted on the disc 16 is a spring-controlled curved arm 23 carrying a roller 24 and ending in a projection 25 extending through an opening in the disc. A curved flange en the arm 23 partially embraces a curved flange 33, Fig. 4, on a spring-controlled plate lever 34 pivoted on the housing 13. A spring-controlled lever 39 is pivotally mounted in an opening 38 in the housing 13 and carries a pivoted pawl 41 provided with a curved tongue 44 and with a tooth 42 to engage a lug 43 on the plate lever 34. When the plough is to be lifted, the control lever 39 is pulled forward and the tooth 42 moves the lever 34 and thus pushes the pivoted arm 23 outwards until the roller 24 engages the corrugated wheel 11. The lifting-disc is carried round for about three-quarters of a revolution until the pivot pin 18 of the lifting-arm 20 passes the dead centre and a projection 45 on the housing 13 strides the projection 25 on the arm 23 and thus disengages the roller 24 from the wheel 11. A projection on the disc 16 lifts the pawl 41 and engages with the tooth 42, and another projection abuts against the stop 45 on the housing. The plough drops when the pivot pin 18 is pushed back past the dead centre by the engagement, of the tooth 42 with the projection on the disc 16 on again pulling forward the control lever 39. Movement of the disc 16 is limited by a stop 45a.

A method of simultaneously producing coke fines and coke breeze from a mixture of coal dust and coarser grains of coal comprises injecting a fluid mixture (gas or oil) of the dust and grains through at least one nozzle 3 in the upper part of a shaft 1, and injecting heating gas at two levels into the shaft, (a) at 5, at the level of the nozzle 3, and (b) at 10 near the bottom of the shaft. The gas velocities are regulated so that fine coked material is carried up out of the top of the shaft and coarser material falls down the shaft to form a fluidized bed 11 at the base. Gas is circulated as shown through a cooler 18 to a cooling zone 13 for breeze 14, and through the shaft via the inlets 5, 10, where it is mixed with the heating gases which have been preheated to about 1200‹ C. The coke fines may be cooled by surfaces 34 in the shaft, or by plates or tubes (32) in a hopper 8, see Fig. 3 (not shown), or by contact with a branch of the recycled gas which has been cooled, the reheated gas being returned to the shaft as heating gas or as the fluid carrier for the coal. In a modification, Fig. 4 (not shown), the shaft 1 and zone 13 are laterally offset, and means for cooling the fines are described. Residence times of 5 seconds for the fines and 10 seconds for the breeze are mentioned.

Abstract: 1287106 Ratchet mechanism STREAMFISHER Ltd 19 April 1971 [20 Feb 1970] 8401/70 Heading F2Q A one-way drive mechanism comprises a pulley 3 secured on a shaft 1 by a nut 4 and keyed or pinned thereto at 5. A sleeve 6 rotatably surrounds the pulley 3 and is grooved from one side and provided with a pin 7 therein about which a lever 8 pivots. A resilient 0-ring 9 embraces the pulley 3. If the lever 8 is pivoted in the direction B it engages a land 11 of the sleeve which then moves freely with the lever about the pulley 3 but if moved in the direction A a land 10 is not engaged and the lever jams between the pin 7 and pulley 3 to move the latter with the shaft 1. A grub screw 12 may be used to adjust the position at which the parts jam and thus the effective stroke in direction A or alternatively a spring may be used in an unadjustable mechanism. If desired, the effective stroke may be varied at different parts of each revolution by making the pulley 3 eccentric on the shaft 1.
