Abstract: 1,019,104. Anti-skid device for braking systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 19, 1964 [June 26, 1963], No. 25488/63. Heading F2F. A motor-vehicle braking system includes a pump device 30 for producing pulsations in the hydraulic pressure to the brake line 22 actuated from a power-driven source 34 but, when there is no pressure in the line 22, is returned by a spring 31 to a position where it is uncoupled from the power source and opens a valve 23, there being between the valve 23 and the pumping space at 31 a biased-closed control valve 27 which puts the system into operation when opened. For normal brake operation the valve 23 is open and pressure from a master cylinder passes directly from the brake line 21 to the line 22. To produce the pulsations in event of a skid a solenoid 24 which opens the valve 27 against its spring 28 is energized by a pedal (Fig. 1, not shown) with or without overriding manual control, or by a pendulum 36 responsive to deceleration of the vehicle. In the latter system a plunger 38, subjected to the pressure in the brake line by way of a throttling aperture 39, acts to urge the pendulum in the opposite direction to the deceleration forces. The power source 34 is a cam driven directly from the vehicle engine, by a flywheel brought to speed by the said engine, or by an electrical motor switched on when the valve 27 is opened. The cam 34 may operate several devices for separate wheels.

Filed: 1929-08-22
Abstract: 334,058. Babcock & Wilcox, Ltd., (Babcock, & Wilcox Co.). Aug. 22, 1929. Ball-and-ring mills. - In a grinding mill for coal &c. having a plurality of superposed circular rows of balls, means are provided for feeding material to be ground to the outside of one of the rows 17 and to cause a current of air to pass upwardly in proximity to the balls along the inside of the rows. As shown the upper row of balls 19 and lower row 17 are separated and driven by a rotary ring 18 which is slotted at 30 to receive arms 29' integral with the driving head 28. The lower balls 17 roll on a ring 6 formed with perforations 12 for the lifting air draught, and the upper balls 19 are pressed down by an axially movable ring 20 which is prevented from rotating by lugs 39. The ring 20 is loaded by spring plungers 41 which contact with stops 48 when the mill is running light to remove the spring pressure from the balls. The head 28 is provided with a conical deflector 32, the base of which is formed with a fan 34. A screen 13 deflects the air draught from the perforations 12 onto the row of balls 17, and a circular screen 35 is supported on a frustoconical screen 31 secured to the rotary ring 18. A screen 11 surrounds the rows of balls and forms with the casing 8 an air chamber for the blast admitted through the inlet 10. A flanged ring 22 is movable axially by screws 24 to adjust openings 23 through which coarsely ground material from the upper ring of balls is carried to the lower ring. The material to be ground is fed through a shoot 50 to the balls 19 from which it passes through the space 23 to the lower ring of balls 17. Air under pressure enters the inlet 10 and flows through the ports 12 und upwardly between the wall 13 and ring 6 where the draught is increased by the help of the fan 23. The air picks up the ground material from the ring of balls 17 and carries it upwardly between the ring 18 and cone 32, slots 31<1> in the frustoconical screen 31 allowing the draught to pick up the fines from the balls 19. The fines then pass to the screen 37 and upwardly over the upper edge of a cone 52 to the outlet 51, the coarse particles falling back on the top of the rotary screen 35 from which it is thrown to the ring of balls 19.

Title: Fluid pressure actuated mechanism for sewing machines
IPC: D05B69/28
Filed: 1953-09-17
Abstract: 740,939. Sewing machines. SINGER MANUFACTURING CO. Sept. 17, 1953 [Oct. 3, 1952], No. 25697/53. Class 112. In a motor-driven sewing machine provided with an operator - influenced clutch arranged between the motor and sewing machine for selectively varying the speed of operation of the latter, a pneumatic or hydraulic motor that influences workengaging means receives fluid under a pressure that varies directly with the speed of operation of the machine. As shown, an electric motor 20 drives, via a variable-speed clutchcoupling, a pulley 21 connected by a belt 22 to the main shaft 16 of a sewing machine. Also directly coupled to the pulley 21 is a pump 72 which delivers compressed air, via a hose 90, to a pneumatic motor 71, mounted on the machine frame, for urging a piston 111 upwardly. The piston rod 70 is pivoted to one end of a blade 60 fulcrumed on a finger 61 fixed to the machine frame, the other end of the blade being adapted to apply thereby a downward controlling force, proportional to the speed of operation of the machine, to the presser foot 35 and upper feeding foot 38 of the latter. The piston is biased upwardly by a light spring 118 for tacking up slack in the blade linkage. The blade is provided with a series of holes 116 for adjustable coupling thereof to the piston rod. A safety valve 85 is provided at the outlet of the pump. Cooling.-In a modification, air released by the safety valve 85 is utilized to cool the needle. Feed by needle and presser foot.-A needle 25 is carried by a needle bar 26 mounted in spaced bearings 27 on a rocking frame 28 and connected for reciprocating movement by a rod 30 to a crank 29 fixed to shaft 16. Frame 28 is fixed to a shaft 31 oscillated from shaft 16. Feeding foot 38 is carried by a feed-bar 39 mounted in a bearing 40 on frame 28. Work engagement.-The presser foot 35 is carried by a presser bar 36 mounted in stationary bearings 37 and prevented from rotating by a guide bracket 41 fixed to the presser bar and engaged slidably with a guide rod 42. A lever 43 is pivoted at 44 to the machine frame and at 45 to the feed-bar. A bell-crank lever 47 is pivoted at 46 to lever 43 and has one end 48 disposed in a slot 49 in the presser bar, the other end being connected by a link 51 to a rock lever 52 fixed to a shaft 53 oscillated from shaft 16. The blade 60 bears, via a steel ball 63, on the lever 43 and thereby normally urges the feeding foot into engagement with the work. Oscillation of shaft 53 causes lever 47 to fulcrum about the pivot 46 for raising and lowering the presser foot. However, when the presser foot is in contact with the work, lever 47 then fulcrums about the point of contact between end 48 and slot 49, whereby continued turning movement of lever 47 serves, by means of pivot 46, to turn the lever 43 and thus to raise the feeding foot. The mechanism is timed to raise the feeding foot during its forward movement and to lower it during its rearward, or feeding, movement. Specification 639,515 is referred to.

Abstract: 838,236. Edging leather articles. TOSI, R. Aug. 15, 1957 [Nov. 22, 1956], No.25781/57. Class 42 (1). A process for edging a leather article 1 consists in skiving the edge 2, applying a layer of thermoplastic material 3 obtained from polyvinyl acetate resins on the skived edge and turning over a marginal section 4 of the edge so that it adheres to the layer. The thermoplastic material is applied to the article when hot by an apparatus wherein the material is exuded from a heated container by a screw conveyer on to the skived edge of the article. Another machine reheats the thermoplastic material by pounding with an electricallyheated hammer before passing the article through a channel or groove which turns its edge which then adheres to the heated thermoplastic material. Adhesion may be assisted by applying solvents to the thermoplastic.

Abstract: 258,255. Vlahov, G. Sept. 14, 1925, [Convention date]. Counters actuated by revolving mechanism.- In a taximeter wherein the fares registering dials are mounted on separate spindles a flexible resetting mechanism adapted to be brought into frictional engagement with the spindles is provided and is controlled by the flag spindle. A vehicle wheel drives a shaft 10, Fig. 1, having a cam 12 for oscillating a lever to actuate a slide 15 against the action of a spring 16. The slide 15 has pivoted thereto an actuating pawl 28 and transfer pawls 32, 40, 48 which on the reciprocation of the slide actuate the ratchet wheels on the shafts 18 - - 21 of the indicating dials the movements being controlled by notched discs 31, 44, 50 co-operating with the projections 34, 43, 149 on the transfer pawls. Overthrow of the shafts is prevented by the ends of the pawls co-operating with fixed pins 39, 38, 47, 53. The pawls are arranged alternately on opposite sides of the slide 15, the ratchet wheels and discs being disposed on their shafts accordingly; the detent pawls 54 are similarly arranged on a slide bar 55. Zeroizing mechanism.-Zeroizing of the dials is effected under the control of the flag shaft 56. When the shaft is rotated, projections 71, 57 through levers 59, 73 effect the disengagement of the actuating and transfer pawls and the withdrawal of the detents. On the movement of the slide to the left, Fig. 1, the pawls 28, 32 are raised by the projections 63, 65 thereon contacting with the pin 66 and the remaining pawls are raised by the ends of a pawl engaging a pin on the succeeding pawl, the pins passing through slots in the slide 15 as shown. The detents are freed by their ends engaging fixed pins 84. Rotation of the flag shaft through a projection 197 rocks a lever 98, Fig. 4, to which is attached one end of a flexible belt 101, the other end being secured to a spring-controlled drum 103. The movement imparted to the belt by the rocking of the lever 98 is transmitted to the shafts 18 - - 21 until the pins 105 on said shafts contact with the pins 86 which are carried by a slide 87 and have been moved into the path of the pins 105 by the slide-operating lever 92 rocked by the pin 93 of a disc on the flag shaft.
