Abstract: 147,615. O'Leary, W. J., (Assignee of Allison, H.). March 18, 1914, [Convention date]. Mechanical toys. - Relates to a walking toy adapted to travel on a stretched and inclined cord &c. under the action of gravity. The figure has arms 22 carrying weighted rods 24 which serve to balance the toy and may represent flags. The legs 10 are loosely pivoted to the ends 18 of an axis 12 bv forked pieces 13, the inner parts 16 of which are slotted to engage the axis. The legs are connected by a slotted frame 29, and a spring or rigid arm 34 fixed to the body projects downward and engages the slot. The slot has inclined ends to give a jerky action to the figure.

Filed: 1926-08-10
Abstract: 279,193. Fell, L. F. R. Aug. 10, 1926. Crank-actuated pumps; multiple-acting piston pumps; regulating delivery by opening by-passes and closing suction valves.-A fuel pump for internal-combustion engines comprises a sleeve &c. 2, 3 with axially displaced ports 5, 14, and a. plunger 4 in the sleeve in the longitudinal and transverse ports 12, 18, the plunger and sleeve being relatively rotatable to vary the amount of fuel delivered, or the period of injection. The ports 5, 14 are open to the fuel inlet 18 by passages 17, 15, 16, and during the down stroke of the plunger, fuel enters the barrel through the ports 5, and passages 13, 12. During the first part of the upstroke the passage 13 is open to the ports 14 and no delivery takes place. Delivery takes place when the passage 13 is closed by the portion 29 of the sleeve between the ports 14 and 5. The edges of the ports 14 are inclined, so that by rotating the sleeve or piston the quantity of fuel delivered and the period of delivery may be varied. The sleeve may be rotated by means of a worm 25 engaging a worm-wheel on a nut 21 meshing with a screwed portion of the sleeve. The sleeve may also be adjusted axially by rack and pinion 23, 22 to vary the moment at which delivery begins. Delivery ceases when the passage 13 opens into the ports 5. By this arrangement, delivery takes place only during the period of greatest acceleration of the plunger. A relief valve may be provided near the inlet 18. Leakage past the plunger may be returned to suction bv a piston 30 attached to the plunger and working in a liner 31 provided with ports 34 communicating with the suction. In the form shown in Fig. 9, the sleeve 3 is fixed and the plunger 4 is angularly adjustable. The ports 14, 5 in the sleeve are connected by passages 16 and are connected to inlet 37 and outlet 37<1> by annular channels 5<1>, 15.

Filed: 1922-07-18
Abstract: 183,458. Korting Akt.-Ges., Geb. July 19, 1921, [Convention date]. Cylinders receiving liquid fuel.-In an engine having a single chamber a communicating with the working cylinder by a narrow neck d, the width of the said chamber being greater than the distance between the upper end of the neck and the point of entry of the fuel nozzle, the fuel is injected across the chamber a into the neck d where it encounters a rapidly moving stream of air or gases. The chamber a and neck d are provided with separate or combined water jackets and the thickness of the walls of the neck may be varied to suit fuels of different density, by providing mterohangeable necks with walls of different thickness. The neck has a smaller opening towards the working cylinder than towards the chamber a and may be coated with a catalyst to promote ignition. The chamber a is made of substantially hollow conical form to minimize the spreading effect of the air entering from the cylinder on the jet.

Vehicle washing apparatus for cleaning the rear end of a vehicle 10 as the latter is moved forwardly in the direction A comprises a frame 11 carrying one or more rotatable brushes 12 and cleansing liquid supply means 13, and guide means 16 to ensure that the frame 11 moves forwardly as it moves from an uppermost position to a lowermost position whereby the brush or brushes is/ are maintained in contact with the rear end of the vehicle. The guide means comprises a pair of inclined wires or rods 16 secured between a floor and roof and tensioned by turnbuckles 17. The frame 11, slidable on the wires or rods 16, is connected with a counterweight 20 by a cable 21 and with a winch 19 by a cable 18. A distance wheel 15 on the frame prevent excessive pressure between the brush or brushes 12 and the vehicle 10, which brush or brushes is/are driven by an electric motor or motors. The liquid supply means in the form of a rotatable perforated pipe 13 has secured thereto a splash shield 14 and a feeder wheel 4 to contact the vehicle surface and ensure that liquid is directed in close proximity to the brush or brushes 12. In operation the apparatus is raised by the winch 19 and the vehicle driven thereunder with the wheel 4 and brushes 12 in contact with the roof. When the brushes reach the rear end of the vehicle the whole apparatus descends under control of the counterweight and winch and the wires 16, the forward speed of the vehicle being dependent on the inclination of the wires and the rate at which the apparatus is allowed to slide down the wires in order to maintain contact between the rear of the vehicle and the brushes. Specification 719,812 is referred to.

Abstract: 406,010. Control of D.C. motors. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. July 15, 1932, No. 20137. Convention date, July 20, 1931. [Class 38 (iii).] In electric locomotives in which unidirectional current is supplied to the driving motor by a metal-vapour rectifier, at least one anode or set of anodes of the rectifier is employed only during starting and one other anode or set is brought into use only after the initial starting and employed during normal running, the anodes or sets being correspondingly dimensioned and only a fraction of the full working voltage being supplied to the starting anode. Current is supplied to the motor 5 from a transformer 3 through rectifier anodes 8, 9. During starting, the potentials of grids 7, 7<a> respectively associated with the anodes 8, 9 are controlled as by switches 14, 19 to allow the arc to pass to the anodes 9 and to stop the arc to the anodes 8. When a predetermined speed is attained, the arc to the anodes 8 is started and that to the anodes 9 suppressed. The anodes 8 may be connected to the full-voltage terminals of the transformer 3 and the phase of the voltages on the grids 7 controlled to increase gradually the effective potential, or the anodes 8 may be supplied with potentials increasing from or through the potential of the lowvoltage tappings 11, for example, as shown by tappings 12 and switches 15. The passage of current to the anodes may be controlled by external switches alternatively or additionally to the grid control. Two or three sets of starting anodes connected to two or three transformer tappings may be used. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which the rectifier has only one anode or set of anodes and in which the potential on the anode is progressively increased by voltage distributors and transformer tappings. This subject-matter does not appear in the Specification as accepted.

A pendulum @, Figs. 1 and 4, with an adjustable bob 2 is pivoted at 5 to the vehicle frame, and its upper arm carries an oiling-device pivoted at 6, consisting of two felt pads 7 backed by springs 10. A pad is brought into contact with one side or the other of the wheel flange 11, according to the direction in which the pendulum swings. and being pivoted at 6, the pad' rests against the flange by its weight only. Oil from a reservoir 20 is supplied to the pad which is operating by a rotary valve 18, which has two chambers delivering to two outlets, as shown in Fig. 6. The valve is controlled by an arm 19 connected by a pin and slot 16, 17 to the upper end of the pendulum. The reservoir is furnished with a regulating-valve 25. A separate lubricator is provided for each wheel. In a modification, the swing of the pendulum is assisted by electro-magnets, the current to which is controlled by a second pendulum suspended from the pivot 6. Fig. 11 shows a device for lubricating a rail 39 by a pad 7' carried by a crank lever 38 pivoted at 37 and connected at 36 to the upper arm of the pendulum.
