IPC: B62K25/22
Abstract: 109,494. Slaughter, T. Sept. 21, 1916. Spring devices.-In a shock-absorber for the frames of motor-cycles, motorcars, &c., an axle is connected to a barrel or shell in the frame by a nut, the endlong movement of which is controlled by springs or other resilient media. As shown in Fig. 1, the nut B is splined to the shell C and engages with a thread upon the axle A, the movement of the nut being controlled by helical springs D, E bearing at their outer ends against abutments F. Alternatively, the nut may be splined to the axle and engage with a thread upon the inside of the shell. The absorber mav be fitted at the crown of the front fork of a motorcycle, the limbs being secured to the spindle; or it may be fitted at the pivots of a link-mounted front fork. In the case of a cycle rear-wheel mounting, the spindle may constitute the pivot of the chain stays, or the absorber may be carried by the upper part of the seat tube and arms, such as I, connected adjustably to pivoted back stays. According to the Provisional Specification, the outer ends of the spring have abutment on the axle, and rubber or like blocks may be used instead of springs.

Title: Improvements in or relating to severing mechanism for sheets and the like
IPC: B26D5/22
Filed: 1929-04-09
Abstract: 330,054. White, A. E., (Upson Co.). April 9, 1929. Rotary-blade machines.-A severing or shearing machine particularly for cutting wallboard includes a rotary severing device which is associated with two transmissions of different speed ratios, one of which normally rotates the device during the non-cutting part C, Fig. 2, of its movement while the other drives the device at a higher speed equal to the speed of the moving work during the operative cutting travel A. The board B delivered from the machine passes along a roller runway 2 and is cut into lengths by knife element 7 mounted in upper and lower rotary knife holders 3, 4 respectively. The knife holders are adjustably mounted on a frame 6. A motor shaft 9 is connected through a reducing gear box 10, shaft 11, gearing 14, 15, and clutch coupling 16, to a shaft 17 which through gearing 18, 19 drives a shaft 20 operating the knife holders. The coupling 16 is normally engaged by a spring 22 and this drive gives the quick operative travel of the knives over the arc A. The pinion 15 is also connected through a loose pinion 36, gears 37, 39 and tumbler change gears 41 to a shaft 35 carrying a pinion 47 engaging an overrunning gear 48 on the shaft 17. The clutch 16 is operated by a cam 23 on the shaft 20 which acts through a lever 28 and yoke 30. Thus, in operation, during the quick travel of the knife holders the clutch 16 is engaged and the clutch element 50 overruns its driving gear 48, and at the end of this travel the clutch 16 is disengaged and the gear 48 then takes up the drive until the cam 23 again becomes operative. The length of the severed sheet is controlled by the duration of the slow movement of the knife holders, and this may be adjusted by means of the change gears 41.

Title: Improvements in or relating to assemblies for effecting relative rotation of a pair of members, and methods of assembling such assemblies
Inventor: NORTON SAMUEL H
IPC: F01L1/32
Filed: 1958-04-08
Abstract: 888,006. Ratchet gearing. THOMPSON PRODUCTS Inc. April 8, 1958, No. 11084/58. Class 80 (3). [Also in Groups XXVII and XXIX] Incremental rotation between the parts of an assembly, such as a valve, on relative axial movement thereof, is caused by a helicallycoiled spring 28 contacted by two annular surfaces 26, 27 on one part of the assembly and by a further annular surface 18 on another part of the assembly, the two parts being axially restrained for maintaining the helically-coiled spring in a pre-loaded condition. The surface 18 has grooves 50 with tapered side walls to engage the coils of the spring 28 and is formed on a retainer 10 locked against rotation on the valve stem 37 by a member 42. The surfaces 26, 27 form part of a collar 11 having a rim 29 spun or crimped over the retainer 10 after the latter has been pressed down to subject the spring 28 to a pressure equal in amount to a contemplated axial minimum load, such as the normal valve spring pressure, and at the same time rotated to cause the coils of the spring 28 to tip over. A spring 39 abutting a member 31, which may be part of an internal-combustion engine, and a surface 24 on the collar 11 loads the valve and prevents the collar from rotating relative to the engine. During opening movement of the valve, the coils pivot at C and during closing at B so that the valve does not return to the same position on its seat. The surface 18 is inclined at an angle of between 20 and 30 degrees and preferably at an angle of 25 degrees to the surface 26. The spring 28 may be replaced by a number-of smaller springs, and in an alternative construction, it is interposed between the spring 39 and the engine.

Title: Improvements in grinding or crushing mills
IPC: B02C15/02
Filed: 1929-04-10
Abstract: 331,877. Robinson, G. H. April 10, 1929. Roller-and-ring mills are provided with means for imposing an initial load upon the rolls so as to produce a grinding action between the same and the grinding ring before centrifugal action comes fully into operation. The grinding rulls d are each mounted in a carriage c pivoted to a carrier or spider b, the direction of rotation being such that the rolls lag behind the points c' at which the carriages are pivoted to the carrier. The carrier b is mounted on a vertical or horizontal spindle a which is driven direct or through bevel gears l enclosed in a casing containing oil which is pumped through the bearing by a pump v. Each carrier c is bored to receive a fixed spindle g on which is mounted a roller d either by ball or roller bearings or by a sleeve. The roller d is recessed at each end to take a ring i and thrust washer k, piston ring packing being inserted in the circumference of the rings i to prevent escape of oil from the bearings which are supplied with oil from a central bore m in the shaft a through flexible tubes n and ducts n<1>, n<2>, n<3>. The carrier is provided with upper and lower discs o, o' to prevent access of material to the springs q or r which press the rollers d against the grinding ring e. The springs r may be of ribbed rubber formed in such manner that the load is not unduly increased as the rubber is compressed. The material to be ground is fed in by a screw s<1> whereby it is distributed to shoots or scoop-like devices t rotating with the mill and having their delivery ends located in advance of the corresponding grinding roll. A plough u, rotating with the mill, picks up and delivers the material which has passed through the rollers, back again to the rollers for further grinding. The ground material. may be removed by a current of air.
Patent GB-542843-A (GB)
Title: Improvements in or relating to railway signalling systems and apparatus
IPC: B61L19/06
Filed: 1940-07-02
Abstract: 542,843. Railway signalling &c. systems. STANDARD TELEPHONES & CABLES, Ltd., BROWN, A., and MARSHALL, T. A. July 2,1940, No. 11156. Addition to 496,495. [Class 105] In a route-setting system of the kind described in the parent Specification, and also in Specifications 516,800 and 520,580 which are referred to, using multi-position switches (preferably sequence-type switches as used in the Rotary system of automatic telephony) controlled by manual operation of selective control means appropriate to the desired route, provision is made for the large number of cams necessary to deal with a complicated layout by the use of two or more switches so associated that one is controlled in the usual way and acts as a master switch the movement of which is followed by the other or others acting as slave switches. The switches are driven from rotary shafts through electrically controlled clutches. A single proving relay circuit is used with the associated switches to prove that the slave switches have moved to and actually stopped in positions corresponding with that of the master by including cams and a clutch contact of the slave switch in series with the existing proving relay of the master switch. Contacts are included in the usual way to ensure non-setting of conflicting routes and other safety conditions. The invention is described as applied to the circuits of Specification 520,580. Fig. 1 shows the positioning circuit for a master switch No. 1 and its proving relay 1PR including, inter alia, master switch cams 1A .. 1M and cams 101G-101N of slave switch 101, together with a slave switch clutch magnet contact 101RC3 in the 1PR relay circuit closed only when the slave switch is de-clutched and stopped. Fig. 2 shows the connections between the master and slave switches, including master cams IT .. IX and slave cams 101A .. 101F and 1010, together with a slave clutch relay 101R which when energized closes the circuit of sla ve clutch magnet 101RC, not shown. Assuming, for example, it is desired to set up as a selected route, Route No. 5, master and slave switches being in normal home position, panel control is effected in usual way and the master switch moves to corresponding position 5. Relay 1PR is not, however, energized until slave cam 101G assumes corresponding position to close the relay circit, and has stopped to close contact 101RC3. Movement of the master switch closes the circuit of relay 101R over cam IT (closed in all positions except home), and cam 101B (made only in home position). The slave clutch magnet is thus operated and the slave switch moves the circuit being maintained over cam 101A until position 5 is reached and cam 101G correspondingly positioned, this cam closing the 1PR circuit only in position 5. On restoring panel control to normal, the master switch drives through successive route selecting postitions to the last such position, the circuit of relay 101R being then maintained from this position to the home position by cam 1010.

Title: Methods of and devices for simulating the orbital welding of tubular members in a fixed position
IPC: B23K9/025
Filed: 1974-03-13
Abstract: 1459123 Welding by fusion SOC ENTREPOSE GTM POUR LES TRAVAUX PETROLIERS MARITIMES 13 March 1974 [22 Aug 1973] 11193/74 Heading B3R To simulate orbital welding of fixed tubular members, two flat metal workpieces 12a, 12b are held in a common plane to present a rectilinear butt-weld preparation, the workpieces and a welding head 23 are together rotated about a horizontal or inclined axis A transverse to said preparation, and simultaneously the head is moved along said preparation, so that molten weld metal successively passes through the various positions adopted during an orbital welding. In Figs. 1-3, a rectilinear seam arc welding machine for simulating orbital arc welding, comprises a main support 6 adjustably tiltable about an axis 3 by a screw-and-nut device 4, 5, a circular frame 9 fast with a normally horizontal shaft 8 journalled in the support 6 for rotation about the axis A, a table 10 pivotally supported on the frame 9 about an axis B perpendicular to the axis A, and a tray 11 fast with and disposed perpendicularly to the table 10. The table and tray 10, 11 are pivotable about the axis B by a screw-and-nut device 25, 25b. The table 10 is split to provide an adjustable table gap 10c and has grooves and holes permitting clamping thereon of the flat metal workpieces 12a, 12b to be butt-welded together. The tray 11 mounts a carriage 15 which is movable along a path parallel to the axis B by a screw 17 driven by a motor and reduction gear 18. The welding head 23 is detachably and adjustably mounted on the carriage 15 by devices 22a, 22b. Current supplies for the motor 18 and the welding head are fed through a slip ring device 19, and gas may be fed to the head 23 through a distributer and conduit 28, 27, Limit switches 20a, 20b and 21a, 21b in the circuit of the motor 18 respectively determine maximum and predetermined limits of welding head travel. A motor and reduction gear 29 provide for plate 9 rotation. Control means in a cabinet 30 provides for independent variation of welding head travel speed, frame rotation speed and head energization, such control means being, e.g. electro-mechanical, electronic, hydraulic or pneumatic. The use of consumable wire electrodes is referred to. Simulation of a complete circumferential seam may be achieved by providing flat workpieces of length equal to or greater than # x diameter of pipe and welding of which is simulated. The apparatus permits observation of the welding from both sides of the workpieces, and, by slowing or stopping rotation of the frame 9 without altering the welding head travel speed, elongation of critical parts of the seam for better observation. The machine may also be used for test butt welding of flat workpieces in the flat, overhead or horizontal-vertical positions with suitably angularly adjusted and stationed frame and table 9, 10 or in an inclined position with the table stationed at 90 degrees to the frame, as shown, and the frame suitably angularly adjusted.

Title: Improvements in fuel injection pumps
IPC: F02D1/04
Filed: 1961-03-28
Abstract: 986,111. Fuel injection pumps. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE. March 28, 1961 [March 30, 1960], No. 11246/61. Heading F1A. [Also in Division G3] Pistons 11 in a rotating shaft 2 are reciprocated by a fixed annular cam 14, the shaft carrying a centrifugal governor which varies the injection timing at low speeds and controls bypass passages 4, 5 at high speeds. A sleeve 6, having a liquid-tight fit on the shaft 2, is provided with a number of holes 7, 9, the number of holes being equal to the number of engine cylinders, four in this case. The passages 4, 5 are at about 120 degrees to each other and are inclined to the shaft axis in opposite directions. A control sleeve 22 operated by the governor slides over the sleeve 6 and shoulders 22a, 6a on the sleeves abut before a spring 29 is fully compressed. The thrust from springs 30 is transmitted by a pivoted lever 32 to the sleeve 6. Alternatively, a spring 30a may replace the springs 30, in either case the spring 29 being the weaker. A pin 35 slides in a groove 36 in the sleeve 6, the groove being inclined to the axis thereof, and a pin 37, fixed to the casing 17 slides in an axial groove 38 in the sleeve 22. The sleeve 22 has four passages communicating with the four holes 7, 9. During the delivery strokes of the pistons 11, fuel escapes through hole 7, until the sleeve 6 closes the passage 4 whereupon fuel is delivered to an injector, via conduits 1, 19, 20. Injection ceases when the hole 9 communicates with the passage 5 and during the suction stroke fuel enters the conduit 1 via conduits 15, 16 and possibly hole 9. This cycle is repeated four times during one shaft revolution in a four-stroke four cylinder engine. Rotation of the sleeve due to the pin 35 sliding in the groove 36, varies the timing and when the shoulders 6a, 22a abut and an increase in speed causes the member 24 to move the sleeves 6, 22 against the action of the springs 30, the fuel flow is reduced owing to the axial inclination of the passages 4, 5 reducing the angular displacement therebetween. To suit the operating characteristics of different engines the grooves 36, 38 may alternatively be wholly axial or partly inclined and the load on the springs 29, 30, 30a may also be varied either initially or when the engine is running in the case of spring 30.

Abstract: 659,139. Drying gases; cooling gases. AKTIEBOLAGET ENKOPINGS VERKSTADER. April 28, 1949, No. 11336. [Classes 34(i) and 64(iii)] An apparatus for the continuous cooling or drying of a gas comprises two equal cooling elements 3, 4 each mounted in a casing 1, 2 respectively. In each casing a reversible fan 5, 6 respectively is mounted above each element 3, 4 the fans working in opposite sense either by opposite rotation or by having left hand and right hand blade respectively. The casing 1, 2 are built together with a passage 9 closed by partition walls 7, 8 said passage having an electric heating element 10, the passage being extended to have an air inlet 11 and an outlet 12. The passage has above nd beneath partition 7 flap valves 13a, 13b and 14a, 14b respectively which open by swing- ing as shown by the arrows. Similar valves 15a, 15b and 16a, 16b respectively are fitted above and beneath partition 8, the valves 15a, 15b opening in the same direction as 14a, 14b. All valves operate by the suction or pressure action of the fans. If the air is to be cooled over the element 3, fan 5 draws air through inlet 11, through valve 13a over the element 3 and through outlet 12 via valve 16a. Simultaneously the air containing in passage 9 circulates through casing 2 valves 14b, 15b being opened, and the air which has been heated by element 10 causes the melting of any ice which has formed on element 4. Reversal of the fans causes the other element 4 to be used. To dry the air the cooling elements 3, 4 are replaced by moisture absorbers consisting for example of silicagel.
