W., 183, Hohenzollerndamm, Wilmersdorf, and DEUTSCHER VERSICHERUNGS - VERKEHR AKT.-GES., 1, Gosslerstrasse, Dahlem, both in Berlin, both in Germany. Nov. 20, 1929, No. 35537. Convention date, Nov. 20, 1928. [Classes 106 (i) and 106 (iii).] Counters with recording-apparatus.-Comprises a device for checking, for insurance and taxation purposes, the distance travelled by a vehicle by printing an initial and final reading of an odometer on a card inserted in the device, the card being held in the device and prevented from removal from before the printing of the initial reading until after the printing of the final reading. The visible odometer 2 and type-wheel odometer 16 are actuated from the double arm lever 25 pivoted at 25a and actuated by the eccentric pin 26 on the worm wheel 27 engaging with the worm 28 driven bv a shaft 29 connected bv a flexible shaft to a rotating part of the vehicle. A correcting drive of known kind is inserted between the shaft 29 and worm 28 to enable the odometers 2, 16 to register distances travelled backwards. The card 5 is inserted through the slot 30 in the casing 1 into the card holder 18 so as to be visible through window 4 and a key inserted over the triangular end of the shaft 7 and turned in anticlockwise direction to cause firstly the cam 8 to engage with the cam 11b, Fig. 5, and force into the card 5 the needle 11 linked to a spring-controlled lever 12 pivoted on the card holder to hold it securely; secondly the cam 9 to engage with the pin 14a on the lever 14 pivoted at 14b and operate the spring- controlled printing platen 15, pivoted at 14c on the lever 14, to print on the card the initial reading of the type-wheel odometer 16 ; and, thirdly, the nose 10b of the cam 10 to engage with the pin 18b secured to the card holder 18 and move the card and card holder into a lower position. The key is then removed from the shaft 7. When an appropriate distance is travelled, the key is applied to the shaft 7 and turned in a clockwise direction to cause, firstly, the cam 9 to engage with the lever 14 and print on the card the final reading of the odometer 16 and the number of the vehicle from the type bar 17; secondly, the cam 8 to become disengaged from the cam 11b and release the pin 11 from the card 5; and, thirdly, the nose 10a of the cam 10 to engage with the pin 18b and raise the card holder with card to the upper position where the card can be removed from the casing. When the card holder 5 moves to its lower position it causes the bar 19 to oscillate a spring-controlled lever 21, Fig. 3, to operate a counter 3. Differently marked cards, e.g. cards of different colour, are employed for different sizes of conveyances.

Title: Improvements in selection means for letters, small parcels and like articles, and in article conveying and depositing means including said selection means
IPC: B07C3/00
Filed: 1957-11-20
Abstract: 824,076. Letters sorting. PITNEY & BOWES Inc. Nov. 20, 1957 [March 5, 1957], No. 36137/57. Class 78 (1). In apparatus for conveying sorted articles, e.g. letters and small parcels in containers 2 from a sorting station to deposition points corresponding with the addresses on the articles, a shaft 19, Fig. 5, movable with each container and having wheels 29 mounted slidably thereon to two alternative positions, co-operates with a number of blocks 30 equal in number to the wheels and arranged in their path, each block having at least one depression 78 and one flat portion 77, the arrangement being such that the releasing device for the articles is operated only when the shaft moves towards the blocks as shown in Fig. 6 by virtue of each wheel being located in its associated depression. The containers 2 are supported on a track 6, Fig. 1, by rollers 4 and are connected by a linkage 3 so designed that they remain horizontal as they pass from one run of the track to the other. The containers are driven by lugs 9 projecting from a chain drive 8. Each container is divided into compartments 11a, Fig. 2, having hollow walls by metal sheets 12, the bottoms of which are closed by pivoted doors 14. A shaft 19 extends through each hollow wall and passes out through a circular aperture in the wall 181 of the container and through a vertical slot 24 in the other wall 18. A roller 22 at one end of the shaft runs on a track 23 and on the other end of the shaft are mounted a member 26 controlling the operation of the door 14, a roller 27 moving in a channel 28 and preventing endwise movement of the shaft, and the wheels 29. The member 26 has a depending portion 33 in which is formed a shallow groove 38. This groove receives a pin 37 mounted in the end of an arm 36 which is keyed to the door shaft 16. When the shaft 19 is lowered, the part 33 is engaged by a stop 34 and the consequent rotation of the member 26 releases the pin 37 so that the arm 36 drops and the door is opened. When the part 33 becomes disengaged from the stop, the member 26 is returned to normal position by a spring 39. The right hand end of the shaft 16 carries a resetting lever 41, Fig. 10, which on engaging contact 42 closes a circuit including a solenoid 43 when an over-riding switch 44 is closed. This causes a trip 46 to move upwards into the path of the lever 41. The switch 44 may be closed by the passage of a letter into a compartment. A trip 51 is provided for use when the containers are moved in the opposite direction. Each wheel 29 has a garter spring 53, Fig. 11, mounted in a channel 52 in its hub. Each spring can be engaged with either of two grooves 54a, 54b in the shaft to retain a wheel in either of two different positions. The wheels are moved for presetting at equal intervals along the shafts by independently-operable frameworks movable axially of the shafts.

Title: An improved method of and apparatus for forming flanges or shoulders on conduits
IPC: B21D17/02
Filed: 1939-12-14
Abstract: 530,368. Flanging. KELSO, A. Dec. 14, 1939, No. 36408/38. [Class 83 (iv)] Copper and other ductile and malleable tubes are flanged in an apparatus in which the tube is held between half dies 8 having flanges sliding in guides in uprights projecting from the base 1. The lower die is secured at 9 to the base and the upper at 12 to a member 13 also sliding in the guides. Clamping pressure is applied by means such as a screw 19 pivoted to the base. A removable bar 21 prevents the screw from slipping laterally during the application of pressure. The surfaces of the dies have means such as a fine screw thread to increase the holding power and the recess in each die is preferably slightly less than a half cylinder. Pressure is applied by a head 29 adjustably mounted in ram 26 advanced by toggle mechanism 31 operated by a lever armed nut 40. Instead of the two arms shown a longer arm provided with a ratchet may be employed. Projections 43 prevent the folded flange from being unduly compressed. The face of the die 29 may emboss a series of rings in the face of the flange to facilitate making a joint. A projection 45 co-operates with a scale to assist in determining the required initial projection of the tube from the holding-dies. Both the ram 26 and the holding-dies may be actuated by fluid pressure. In a modification the clamping pressure is applied horizontally. The head 29 may have a recess to receive the end of the tube when the flange is to be formed spaced from the end. In a further modification the head may be shaped as at 66, Fig. 10a, to form a conical flange which seats on a complementary cone on another pipe member under the pressure of a union nut.

Abstract: 1,178,838. Valves. J. J. BELL. 16 Aug., 1967 [16 Aug., 1966], No. 36515/66. Heading F2V. [Also in Divisions F1 and H1] A device for operating an aerosol dispensing container discharge valve, a humidifier, a gas or water valve or an electrical circuit, at timed intervals of adjustable duration and frequency, comprises a synchronous electric or clockwork motor 14, Fig. 2, rotating a cam assembly 26, 28, e.g. at one revolution per minute, a cam member 30 being pivoted at 31 to member 26 and having a follower 32 engaging in a cam groove in member 28, so that rotation of member 28 relative to member 26 varies the extent to which member 30 projects from member 26, and hence the duration of lift of the operating lever assembly 78, 18. A spring-loaded detent device holds members 26 and 28 in their adjusted positions, Figs. 9 and 10 (not shown), and a scale on member 28, Fig. 1, indicates the duration setting. To time the frequency of operation, a reduction gear train drives disc assembly 60, 62, e.g. at one revolution per hour, discs 60 and 62 having peripheral grooves of different widths and spacings, and disc 62 being angularly adjustable relative to disc 60 by gearing, Figs. 4 and 5, (not shown), such that from one to six pairs of grooves can be brought into alignment. A detent member 72, 76 is biased by spring 74 into the aligned grooves to transmit movement from a cam follower 82, on a lever 78, to lever 18. When member 76 cannot move into aligned grooves, the cam assembly does not operate lever 18. The rotation of disc assembly 60, 62 once per hour, and the adjustable selection of one to six groove alignments, provides a selection of one to six operations per hour. A cam groove 86 in a disc 84 rotating with cam assembly 26, 28 acts to permit detent member 72, 26 to move into the aligned grooves in discs 60, 62, while cam member 30 is engaging cam follower 82 for drive to be transmitted to lever 18, the disc 84 then holding detent member 72, 76 out of the aligned grooves when cam member 30 moves out of engagement with follower 82. Lever 78 is pivoted at 80, and lever 18 at 19. Lever 18 acts on the aerosol dispensing container discharge valve through a spring-loaded member 17, the container being held by resilient clamps 12 in a frame 10, and enclosed by a cover with an outlet "trumpet" for the discharged contents of the container. The adjustable cam member 30 may be replaced by fixed cam members of different durations. A number of detent members 72 may be provided.
