Title: Improvements in power inching gear for belt driven washing machines
IPC: D06F37/30
Filed: 1945-04-10
Abstract: 590,033. Drying-machines. BRAITHWAITE & SON ENGINEERS, Ltd., I., and O'BRIEN, T. H. April 10, 1945, No. 8824. [Class 34 (ii)] [Also in Group VIII] In a drying-tumbler of the horizontal cylinder type, shock and damage in throwing in a slow gear for inching the cylinder into position for unloading is avoided by connecting the slow drive to the main shaft through a clutch and by the provision of interlocks between the controls for the main and slow drives to prevent their simultaneous operation. The machine is driven from a shaft 2, Fig. 1, provided with fast-andloose main-drive pulleys 1, 4, 5 and connected to a toothed ring 37 on the cylinder through a train of gears 7. The belts of the main drive are controlled by a rod 13 having "on" and "off" positions 14a, 14c and supported in a universal joint 16 carried by a lever 15 pivoted at its lower end to a bracket 17. The slow drive comprises a reduction gear 10, such as a double worm, driven by a belt engaging fast-and-loose pulleys 11, 12 and adapted to be connected to the main drive shaft 2 through a clutch 9. The belt of the slow drive is controlled by a lever 31, Figs. 1 and 3, and the clutch by a handwheel 25 in screw-threaded engagement with the end 23, Fig. 4, of a spindle 22 of rectangular cross-section. Rotation of the hand-wheel thus produces a very slow axial movement of the spindle and consequent engagement (or disengagement) of the clutch, the arrangement being such that the clutch serves as a brake to bring the cylinder to rest before inching begins. Interlock between main and inching drives. To prevent engagement of the slow-drive clutch unless the main-drive control rod 13 is in "off" position, the control spindle 22, Fig. 4, of the slow-drive is apertured to receive a cam 20 on a pivoted arm 18 coupled to the lever 15 which supports the control rod 13 for the main drive. In the "on" position of the control rod 13, the cam prevents movement of the spindle 22 to engage the clutch, and conversely, when the clutch is engaged, the control rod cannot be moved to "on" position. Interlock between cylinder loading door, inching-drive and cylinder restraining means. To prevent accidental movement of the cylinder while it is being loaded or unloaded, a worm 36, Figs. 1 and 3, eccentrically mounted on a spindle 38 is moved into engagement with the toothed driving ring 37 on the cylinder. This movement shifts a bar 41, Fig. 4, longitudinally with two effects; (a) the bar cannot be moved, and thus the worm cannot be engaged with the toothed ring, until the inching-drive spindle has been moved into clutch-disengaging position and vice-versa; (b) the circumferential sliding door of the cylinder cannot be opened until the bar 41 has been shifted by the engagement of the worm with the toothed ring and, conversely, the worm cannot be disengaged until the door is closed.

IPC: B24B33/08
Filed: 1954-03-27
Abstract: 789,312. Grinding and honing. NICOL & ANDREW, Ltd. March 28, 1955 [March 27, 1954], No. 9031/54. Class 60. A grinding or honing head comprises central bosses 1 formed with transverse slots 10 adapted to receive arms supporting carrier members carrying grinding stones or hones; racks on the carrier members engage pinions on a shaft 2 carrying a toothed wheel 3 engageable with internal splines in a sleeve 4 carried by a connecting member 5 coupled to a driving spindle 6 constructed for coupling to a driving head. Spring clips 7 have loops 8 the lands of which are engageable with a shoulder 9 on the member 5. Rotation of the spindle 6 causes the pinion shaft 2 to rotate whereupon the carrier members move outwardly until the stones or hones supported by the carrier members come against the surface being ground or honed ; continued rotation of the spindle 6 then causes the entire head to rotate as a unit. To provide a rapid and large adjustment of the carrier members, e.g., to set them initially at commencement of a new operation, the spindle 6 is moved axially relatively to the bosses 1 a distance sufficient to disengage the toothed wheel 3 and splined sleeve 4, and the pinion shaft 2 is rotated by hand. Specification 723,571 is referred to.

Abstract: 607,286. Extruding. SOC. D'ELECTROCHIMIE, D'ELECTRO-METALLURGIE, ET DES ACIERIES ELECTRIQUES D'UGINE, and COMPTOIR INDUSTRIAL D'ETIRAGE ET PROFILAGE DE METAUX. April 11, 1945, No. 9071. Convention date, Sept. 15, 1944. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 11, 1945.] [Class 83 (iv)] A method of extruding according to Specification 607,285 is characterised by the use of a die having a throat of varying length, being shorter at those parts which are the more difficult to lubricate. When extruding a bar of other than circular section it has been found that effective lubrication between the die and the work is more difficult at the middle of the larger sides of the section and in the region of re-entrant angles. Thus, in extruding bars of triangular section, Fig. 9, or T-section, Fig. 11, e<SP>3</SP> represents the parts most difficult to lubricate, e<SP>1</SP> the parts more easily lubricated and e<SP>2</SP> intermediate parts. In order to provide more uniform lubrication, the throat of the die is made of varying length, being shorter at the parts e<SP>3</SP>. A die for extruding bars of T-section is shown in Figs. 12 and 13, the throat 2 having different lengths at the positions corresponding to the parts e<SP>1</SP>, e<SP>2</SP> and e<SP>3</SP>. The variation in the throat depth may be either continuous or stepped.

Title: Process for relaxing synthetic or artificial filamentary material
IPC: D02J13/00
Filed: 1965-03-03
Abstract: 1,075,981. Relaxing filamentary material. AMERICAN CYANAMID CO. March 3, 1965 [Aug. 17, 1964], No. 9125/65. Heading B5B. Synthetic or artificial filamentary material is continuously relaxed by continuously exposing an upwardly moving endless length of the material to turbulent flow of heated gas moving upwardly in the direction of travel of the material in a confined zone at a velocity sufficient to produce adequate turbulence for uniform and effective heat transfer but not sufficient to disarrange or to elongate the material. Such exposure is for a time and at a temperature sufficient to relax but not sufficient to degrade the material. The filamentary material preferably is fed upwardly into the lower portion of the confined zone at a linear velocity which is higher than the linear velocity at which it is removed from the upper portion of the zone, the gas velocity preferably being such as to eliminate tension on the filaments leaving the zone. The material preferably is dry and may be lubricated before being fed into the confined zone; to minimize darkening of the material, antioxidants (examples of which are listed in the Specification) may be applied to the material prior to relaxation. After leaving the confined zone, the filamentary material may be quenched, for example by cold or ambient air or by water, to prevent restretching. The heated gas may, for example, be air; the filamentary material, which may be in the form of a multifilament tow, may be made from polyamides, polyesters, cellulose triacetate or acrylonitrile polymers. Dry acrylic fibres may be relaxed satisfactorily by exposure for from 0À1 to 30, preferably from 0À5 to 5, seconds to a gas heated to a temperature between 250 and 600 F., preferably between 400 and 550 F. The relaxation treatment may take place in apparatus described, illustrated and claimed in Specification 1,075,982.

Abstract: 455,713. Variable - speed gearing; friction clutches. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.- (Borg-Warner Corporation; 310, South Michigan Avenue, Chicago, U.S.A.) March 23, 1935, No. 9154. [Class 80 (ii)] A vehicle transmission system comprises a reduction gear train and a hydraulic coupling F arranged in parallel between the propeller shaft 11 and a shaft 13, which latter is adapted to be connected to the engine shaft 10 by a centrifugal friction clutch C which engages at a predetermined engine speed and which may be disengaged manually at any time. The clutch C is similar to that described in Specification 422,443. The reduction gear train includes a oneway clutch, and the arrangement is such that at low speeds the shaft 11 is driven through the reduction gear train while at higher speeds the coupling F becomes effective to drive the shaft 11 direct, the one-way clutch then over-running. The annular impeller casing 90 of the coupling F is keyed to the shaft 13 and has a tubular extension 94 carrying a gear 110 which is in mesh with a countershaft gear 111 which drives other countershaft gears 117 and 118 through a one-way roller clutch 114. The turbine runner 91 of the coupling F is secured to a shaft 97 passing through the extension 94 and carrying a gear 133. A gear 123 splined on the shaft 11 is controlled by an arm 131. With the arm 131 in the position R, the gear 123 meshes with an idler gear 135 in mesh with gear 118, and the shaft 11 is driven reversely. With arm 131 in position N, gear 123 is free, and no drive is transmitted. With arm 131 in position F, gear 123 meshes with gear 117 and teeth 124 on gear 123 engage the teeth of gear 133. In this position, therefore, the coupling F and the reduction gear train 110, 111, 117, 123 are arranged in parallel. With arm 131 in position F<1>, the teeth 124 remain in engagement with gear 133 and teeth 122 on gear 123 mesh with wheel 111. In this position, therefore, a direct positive drive is transmitted.

Abstract: 330,668. Fenn, A. G., and Anglo- American Oil Co., Ltd. March 22, 1929. Indicating action of.-A pump for delivering measured quantities of petrol is provided with means, set by the pump actuating mechanism for printing or punching upon a voucher the quantity delivered. The operating shaft 2 of the pump, in which the stroke of a piston determines the quantity delivered, drives a pinion 13. This pinion carries a stepped cam 40 which actuates a roller attached to a member 30 driving, through a ratchet 33, a drum 17 with punches or' type arranged to form numerals. The punches are carried on stems 24 and co-operate with die-plates 23. For each stroke of the pump the member 30 is rotated 50 degrees and the cam 40 is turned five-sixths of a revolution. A yoke 67 carries a slide 53 with projections 59 which engage the punch heads. On hand actuation of a shaft 48 cams 58<a> swing a body 54 and the slide 53 to move a lug 55 above the punch stem. Further rotation of the shaft 48 punches a ticket inserted in a slot 19. On a body 33, rotated with the drum 17, is a grooved boss 64a engaging pins 66 on the yoke 67. The shaft 48 after the punching operation is turned counterclockwise to allow springs to return the punch-actuating mechanism to normal and a cam taps a lever to disengage the body 36 from the drum 17 and withdraw pins 37 from engagement with ratchet teeth 33. The drum is then returned to normal bv a spring- drum 29. A projection on the drum 29 engages the punch actuating mechanism to ensure each sale is recorded. In a modification Fig. 10, the disc 17 carries gag-plates 80 with holes arranged to form numerals. Actuation of a cam 95, through balls 100, raises a die-plate and the ticket, to be punched by puncher 89. A spring- urged ejector plate 90 clears the die-plate of punchings.

Abstract: 791,239. Combustion apparatus. COMBUSTION ENGINEERING, Inc. March 31, 1955, No. 9409/55. Class 51 (1). [Also in Group XIII] A water-tube steam boiler, wherein the steam temperature at loads belowthe maximum is held at the desired value by the recirculation of flue gas comprises a furnace 10 lined with steam generating tubes 14 and fired by burners 12, the combustion gases leaving the furnace at 28 and flowing through a passageway 29 locating successively a superheater 32, an economizer 34, a main air heater 36, the lower compartment 38 of a dust collector 40 and an induced draught fan 42 from which the gases are conveyed to a stack 30. Connected in parallel with the economizer the air heater, the compartment 38 and the fan 42 is a duct 48 having dampers 50, 52 at its inlet and outlet respectively. In the duct 48 is positioned successively an auxiliary air preheater 54, the upper compartment 56 of the dust collector 40 and a fan 58. At the respective outlets from the air heaters 36, 54, the passageway 29 and the duct 48 are connected by a duct 60 controlled by a valve 62. Branching from the outlet of the fan 58 is a duct 76 through which cooled combustion gases may be recirculated to the furnace, the flow in the duct being controlled by a damper 78. The two fans 42, 58 are driven by a single motor 75. Combustion air is supplied to the furnace by a fan 64 which delivers the air through ducts 66, 68, the air heater 36 and a duct 70, the auxiliary air heater 54 being connected in by-pass relation with the duct 66. Flow through the duct 66 and the air heater 54 is respectively controlled by dampers 72. 74. At or near maximum load the boiler is designed to give the proper steam temperature without gas recirculation. Under these conditions the valves 50, 74, 78 are closed and the valves 52, 62, 72 open, whereby both of the fans 42, 58 act as parallel-connected induced draught fans. As the load decreases the valves 50, 74, 78 are moved towards the open position and the valves 52, 62, 72 correspondingly closed, the adjustment being such that the outlet pressure of the fan 58 is increased to above that in the furnace and gas is recirculated to the latter through the duct 76 the flow being controlled by the automatic adjustment of the valves 52, 78' in response to variations in the temperature of steam in the superheater outlet header 44. With this arrangement, a completely separate recirculating fan is not required and the motor 75 need only have sufficient power to handle the volume of combustion gas generated at full load.
