Title: Improvements in machines for inserting pegs in shoes
IPC: A43D69/12
Filed: 1932-09-13
Abstract: 393,811. Nailing-machines. LEY, A., 10, Wollmarkt, Arnstadt, Thuringia, Germany. Sept. 13, 1932, No. 25493. [Class 89 (iii).] Relates to pegging-machines of the kind provided with a cutter arranged in the horn tip for cutting off the projecting ends of the pegs after they have been driven, and consists in the provision of means whereby the cutter and a lock for the horn are actuated directly from the lever which operates the work-feed member, and means whereby the work-feed member may readily be coupled to, or uncoupled from, a cam lever which imparts to it the to-and-fro motion necessary for the insertion of two rows of pegs. The feed member 9, which is hung on a universal pivot 13 and has a serrated feed foot 9a, is lowered to the work, oscillated in the direction of feed, and raised from the work, by a lever 8 to which it is connected by a universal joint 11. The lever 8 receives its appropriate movements from cams 5, 6, 7 on a main shaft 3. The pivot 13 is carried by a two-armed lever 40 mounted on the same shaft 41 as a cam lever 42 adapted to be oscillated by a cam 44. For single row pegging, the lever 40 is locked to the machine frame by a removable pin. For two row pegging, it is locked by the pin to the lever 42, so that the cam 44 imparts a to-and-fro motion to the member 9. The lever 8 is pivoted, at its lower end, to a rod 19 which is pivoted to a bellcrank lever 23. The arm 23b of the latter is connected by a rod 25 to the bell-crank lever 27 which actuates the peg-cutter 16, and by a rod 29 to a bell-crank lever 31 which controls the horn lock 18. Thus, as the member 9 is lowered to the work for its work-feeding movements, the cutter 16 is actuated, and the horn lock 18 is released. The horn lock is held normally in locking position by a spring 33, and can be disengaged at will by a treadle lever 36.

Title: Improvements in or relating to propulsion means for vehicles for movement on land, water or in the air
Inventor: SCHMIDT WILHELM
IPC: B64C23/00
Filed: 1959-07-25
Abstract: 916,667. Propelling vehicles. FORSCHUNGSZENTRUM DER LUFTFAHRTINDUSTRIE. July 25, 1959, No. 25598/59. Class 79(3). [Also in Group XXXIII] A vehicle is propelled by generating a stream of flowing medium, which is deflected by flow diverting means consecutively on to different sides, including two opposite sides, of a body extending in the direction of propulsion. In Fig. 1, a stream of moving fluid 1 generated by an air screw or water screw 2 is directed over a flap 4 oscillated about an axis 3, so that the stream is deflected to impinge alternately on to the opposite faces of a streamlined body 5. This is stated to allow a reduction in the difference between the velocity of the generated stream and the velocity of the surrounding medium, both relatively to the vehicle, resulting in improved thrust and less noise generation. The flap 4 is driven from a shaft 7 through suitable gearing 8 and an electromagnetic slipping clutch 10 controlled by a potentiometer 11. In Fig. 2 the fluid stream passes through a hollow twin shelled body 12, the part of the flow within the annular space 15 being cyclically controlled by revolving shutters 19, 20, to issue alternately through inwardly directed slot nozzles 17, 18 and thus deflect the main flow through the body in alternate directions. Valves 21 control the flow through space 15, and the speed of revolution of the shutters 19, 20 is controlled by gearing 22. In a further embodiment, the flow is divided wholly between two nozzles, each directing the flow on to one face of body 5, and the nozzles are closed cyclically. There may be more than two nozzle, the body 5 then being pear shaped. In another embodiment, the fluid stream is electrically charged or inoculated with charged particles and deflected by an alternating electric or magnetic field. In, Fig. 6, the tail pipe 32 of a jet propulsion engine contains a deflecting element comprising a bullet 33 and eccentric portion 34, which are rotated by a furbine shaft 27 through epicyclic gearing 39. A similar rotating deflector may be used in a slipstream casing downstream of a propeller. The deflector is movable axially for control purposes by a linkage 38. The tail pipe may be surrounded by a duct 35 also conveying the fluid stream. The pipe 32 and deflector 34 may then rotate together. The tail pipe may have an eccentric nozzle instead of the deflector and be rotated. The downstream ends of pipes 32 and 35 may comprise displaceable overlapping plates for varying the outlet areas. The body 5 may comprise members 44, 45 which are adjustable to deflect the fluid flow.

Abstract: 1,084,647. Hydraulic reciprocating motors. C. ASHLEY. June 10, 1966, No.25865/66. Heading F1A. In an electro-hydraulic vibrator, e.g. for testing vehicles, comprising a double-acting piston 13 carrying a load platform 19, liquid distribution to the piston is controlled by three slide valves connected in parallel by stepped passages in a valve block. Figs. 3 and 4 (not shown), such that the volume of the liquid system is small, which increases the resonant frequency of the vibrator. Each slide valve 27 is controlled by an electromagnetically-actuated flapper 37 controlling flow from nozzles 35, 36 and hence the hydraulic pressure, acting at each end of the slide valve 27. The slide valves, indicated (61), (62), (63) in Fig. 3 (not shown), are connected to common inlet, outlet and cylinder passages (28), (33), (29) and (31), each passage being stepped such that the large diameter end takes the flow for all three valves, the middle diameter for two valves and the small diameter end for one valve. The passages are formed by drilling with successively larger drills. The axes of the passages (82) to (85) are arranged on an arc, Fig. 4 (not shown), so that the passages (71) to (74) connecting each of them to a respective valve are substantially the same length. A displacement transducer 44, 45 controls the piston displacement by sending a feedback signal to the flapper The cylinder ports may be directed tangentially to give swirl and increase the flow rate.

Abstract: 750,081. Swash-plate pumps. SCHWEIZERISCHE LOKOMOTIV-UND MASCHINENFABRIK. Nov. 6, 1951 [Nov. 29, 1950], No. 25982/51. Class 102(1). In a variable delivery swash plate pump having inlet ports 28, 29 in the cylinders 3<SP>1</SP>, 3 controlled by the plungers 4<SP>1</SP>, 4, the swash plate 13 is of constant inclination and is movable axially against a spring 27 to vary the effective stroke, by means of the pressure acting on the plungers and also by means of at least one control plunger 34 disposed parallel with the pump plunger axes and subjected to the delivery pressure. Small and large diameter plungers, 4, 41 respectively are arranged alternately or in groups and deliver through ball valves 30,31 into a common pressure chamber 32 communicating with a delivery pipe 33. A total of twelve cylinders are preferable. The pump is supported from the cover 25 of a driving motor 19 and may be wholly or partially immersed in a reservoir of liquid 26. The plungers act on the swash plate through a bearing ring 9 which may alternatively be omitted. The small cylinders 3<SP>1</SP> have additional inlet parts controlled by ball valves 7. The control plunger 34 acts on the swash plate through a disc 15, flanged sleeve 15, 16 and thrust bearing 37 and has a head 39 slidable in a cylinder 40a. The latter may have a part 41 forming a dashpot chamber 47. As the delivery pressure increases the swash plate is moved gradually and the large cylinders are cut out first. When a predetermined pressure is reached a shoulder 46 on the control plunger stem uncovers a port 42 leading to a low pressure chamber 38 and allows the swash plate to move quickly to a no-delivery position. In other embodiments stroke control plungers are alternatively or additionally provided in cylinders disposed outside the pump cylinders and parallel therewith. These plungers act directly on the spring guide member 24 through a sleeve integral with or secured to the flange 15. Specification 636,201 is referred to.

Abstract: 940,922. Centrifugal separators. DAVIDSON & CO. Ltd. June 14, 1962 [July 20, 1961], No. 26331/61. Heading B2P. [Also in Division F1] In a rotary fan, particularly an exhauster fan, having an impeller disposed within a fan casing with a suction eye, for the inlet of dustladen air or gas to the fan casing, disposed in axial alignment with the impeller, the suction eye has the form of a duct or tube containing fixed deflector vanes which impart swirl to the incoming dust-laden air or gas and, located adjacent the junction of the tubular suction eye with the fan casing, there is an annular deflector having a section which provides one flange directed into the tubular suction eye and another flange directed radially outwardly into the fan casing, which flanges are spaced from the walls of the fan casing and of the tubular suction eye. In order to reduce abrasion of impeller blades 1 by dust in the air or gas being pumped, the inlet duct 4 has arranged therein a series of fixed vanes 5 which impart swirl to the incoming dust-laden air or gas. This causes a major portion of the dust to be thrown centrifugally on to inner wall surface 10 leaving relatively dust-free air or gas which passes to the impeller 1, the dust subsequently passing through an annular passage 11, formed between a flange 9 of an annular deflector 8 and the surface 10 and being directed by a flange 12 radially outwardly to by-pass the impeller 1 and pass into the fan casing 3 provided with outlet 7. The deflector 8, which may be of a surface-hardened material, is secured to the casing 3 with spacers 14 by bolts 15 screwed into projections 13 extending substantially tangentially, in the direction of rotation, from the flange 12. The deflector 8 may instead be secured to the tubular suction eye 4. The crosssection of the deflector 8 may be substantially arcuate. In an alternative embodiment (not shown) the projections 13 are omitted and the deflector is secured directly to the impeller and rotates therewith.

Each part T1 to T6 has an associated nut 15 mounted on a disc or spider 45 and in the fully retracted position of the device all the nuts 15, except that of part T1 are positioned on a cylindrical part 16 of the spindle 14, the nut 15 of the part T1 being in threaded engagement with threaded length 14<SP>1</SP> of the spindle 14. Each part T1 to T6 has on its outer surface 25, between upper and lower sliding bodies 20, 21, a stop 23 with upper and lower striking surfaces 26. A complementary striking surface 27 is formed on each upper sliding body 20. Each upper sliding body 20 also has a striking surface 24 which comes into contact with a complementary surface 24<SP>1</SP> on the upper sliding body of an adjacent telescopic part. Each upper sliding body 20 has a spring-loaded looking device 30. From the fully retracted position rotation of the spindle 14 by the drive 3 extends part T1, relesing its locking device 30 in so doing, its stop 23 engaging the upper sliding body 20 on the part T2 thus carrying the part T2 along the cylindrical part 16 of the spindle 14 until its nut 15 can thread on to the threaded length 14<SP>1</SP> of the spindle 14 (as shown), the disc or spider 45 yielding elastically to enable the threads to engage properly. The next spring-loaded locking device 30 engages the innermost end of the part T1 and continued rotation of the spindle 14 thus extends parts T1, T2 as a unit, the nut 15 of the part T1 leaving the spindle 14. Parts T3 to T6 are similarly extended, the spring-loaded locking devices 30 being individually adjusted to ensure the correct sequence. The parts T1 to T6 are retracted in sequence when the drive 3 is reversed. Relative rotation between the parts T1 to T6 is prevented by guide rails 36 and guide grooves 37, rotation of the device about its longitudinal axis as a unit being made possible by members 4 to 7.
