Title: Improvements in cigarette making machines
IPC: A24C5/39
Filed: 1919-10-31
Abstract: 149,152. Bray, A. Oct. 31, 1919. Cigarette-making machines.-A cigarette-making machine is provided with means for opening and teasing-out the tobacco in the hopper, comprising two sets of fingers which grip the tobacco, carry it through the hopper with an oscillating motion, release it, and return to the other end of the hopper to take up another lot of tobacco. The fingers n are pivoted on a shaft d mounted on a carriage operated by a reciprocating arm band running on rollers e<1> on ways g', 'g, h<1>, h, g<3>. The ways g<1>, g are rack-shaped as shown, so as to give a jogging motion to the carriage as it passes over them. The carriage passes along the ways g', g, with the fingers n gripping the tobacco, until it is clear of the way h'. A star-wheel k on the carriage then strikes against a stop i, and causes a cam o to open the fingers n, so that the tobacco drops into the hopper. The way h<1>, which is pivoted, drops as soon as the carriage has passed from under it, so that the carriage on its return journey mounts the way h' and runs along the way h on to the way g<3>, which, being carried by the pivoted way g', falls under the weight of the carriage into the position shown by the dotted lines; the carriage returns along the ways g<1>, g. When the carriage has reached its rearmost position, the wheel k engages with a stop q and the cam o moves so as to close the fingers n. The stop q is carried on a weighted lever so that it moves with the carriage as the latter falls and then returns to its original position.

Title: Process and apparatus for packing cigars in individual coverings by mechanical means
IPC: B65B19/26
Filed: 1931-09-29
Abstract: 376,101. Wrapping machines for cigars. UNIVERSELLE CIGARETTENMASCHINEN-FABRIK J. C. MœLLER & CO., 48, Zwickauerstrasse, Dresden, Germany. Sept. 29, 1931, No. 27107. Convention date, Dec. 1, 1930. [Classes 94 (i) and 94 (ii).] Individual cigars are enclosed in a tube of tissue paper or cellulose material and the ends are closed by folding, twisting, or flattening. A web 2 is fed past printing devices 6 and a tensioning device 4 to a core 5 by which it is formed into a tube H, adhesive being applied at 61. A cutting device 6<11> severs a length which is fed forward by shaped rollers 7, 71 until it embraces a tubular member 8 into which a cigar has been introduced. The cigars are fed into position on a conveyer belt 17, and the member 8 is reciprocated from a left-hand position to the position shown in Fig. 1, where it passes over and encloses the cigar on the band, and continues to a position over a grooved drum 21, where the tube H is applied to it. A finger 9 is depressed into a groove in the member 8 when the latter makes the return stroke ; the cigar and tube is thereby restrained from axial movement and falls into a groove in the drum 21. A plunger 22 pushes the cigar into the correct position in the tube, which is held from movement by a rail 27. A series of folders 28 .. 31, Fig. 4, makes the end folds I .. IV. The folders may be arranged to carry adhesive with them on to the wrapper, and may be arranged to operate on one or both ends of the tube. If one end only is folded, the other may be closed by twisting in an apparatus comprising a rotary longitudinally displaceable sleeve 33, adapted to be moved forward into the position shown in Fig. 5. A collar 34 having conical surfaces 34<1> is moved to rock arms 35, 35<1> so that cheeks 38 are closed upon the end of the tube, which is then twisted by the rotation of the sleeve. The sleeve 33 may be mounted on the drum 21, or may be stationary and operate during pauses in the rotation of the drum. In a modified form of apparatus, the ends of the tube are flattened and perforated, and an adhesive label applied over the ends.

Abstract: 1303914 Clocks and watches SUWA SEIKOSHA K K 19 April 1971 [24 April 1970 (3)] 27138/71 Heading G3T A timepiece case assembly comprises a glasscarrying ring 2 having a depending annular resilient flange 3, a case body 4, and a resilient sealing ring 5 disposed therebetween and in engagement with a surface 7 of the flange and a surface 6 of the case body 4, the ring 5 being substantially I-shaped or L-shaped in cross-section. Several embodiments as applied to a waterproof watch are described. As shown, the glass 1 is secured in a metallic ring 2 by adhesive, and chamfered edges 7a and 5a provide a lead-in when the ring 2 is pressed home into case 4. The provision of the resilient flange 3 enables the ring 5 to be made of a less deformable material than the conventional synthetic rubber and to provide a waterproof seal even at very high pressures. The ring 5 is preferably of plastics material such as polycarbonate or a soft metal such as copper or silver. The surfaces 6 and 7 may be inclined to the central axis of the case, Fig. 6, (not shown), to ensure a good connection between the ring 2 and body 4. Grooves, Figs. 3 and 7, (not shown), may be provided in the surfaces 6 and 7 to receive a part of the sealing ring. The seal-engaging surface of the glass carrying ring may be of greater diameter than that of the engaged surface of the body, Fig. 9, (not shown), such that the sealing ring lies inside the glass-carrying ring, which latter may overline the seal (25) thus rendering it invisible from the front of the watch.

Filed: 1966-06-17
Abstract: 1,153,855. Armatures for electric motors; control of D.C. motors. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 17 June, 1966 [19 June 1965], No. 27208/66. Headings H2A and H2J. [Also in Division D1] In a washing and spin-drying machine, the drum is driven at washing and spin-drying speeds by a D.C. motor with a permanent magnet stator giving a shunt characteristic. The motor may be reversible and the ratio of the sum of the minimum widths b of the rotor teeth to the rotor diameter D is preferably 1À5. The secondary side of a tapping transformer T connected to the mains is connected to a Graetz circuit and the rectified voltage is applied through resistances R 1 , R 2  and switch S 1  to rotor R. Adjustment of the tapping on the transformer varies the speed of the motor for washing and centrifuging. During washing, resistance R 2  is short circuited. After washing, the water falls below the level of the drum and a tap on transformer T is chosen giving a higher voltage, switch S 2  being opened at the same time to increase the resistance. Resistance R 1  may represent the high resistance of the rotor and/or the control circuit. When centrifuging is complete, the supply voltage is cut off and the rotor connected through resistance R 3  for electrical braking by actuation of switch S 1 . In modifications, Figs. 3a and 3b (not shown), closing of switch S 1  also operates a relay controlling a further switch which operates after the motor has been partly braked to reduce resistance R 3  and intensify the braking effect.

Title: Control of conveyors or the like
IPC: B65G23/00
Filed: 1945-10-17
Abstract: 599,049. Endless-belt conveyers. MICKLEY COAL CO., Ltd., TAYLOR, R., and PAISLEY, R. Oct. 17, 1945,'No. 27221. [Class 78(i)] . In a method of controlling a series of conveyers feeding one another in sequence, the actual running of a conveyer at above or below a predetermined speed determines the respective starting or stopping of the next conveyer in the sequence. A roller 1 is mounted in contact with and is rotated by a belt and contains oil or other fluid 2. A spindle 4 is journalled in the roller spindle 3 and has vanes 5 mounted on it which project into the oil. The end of the spindle 4 projects past the end of the roller spindle 3 which is fixed against rotation and is coupled to the operating mechanism of a switch 7 .connected in the circuit of the next conveyer. The vaned spindle has two stop positions to one of which it is carried when the conveyer is running at its normal speed and to the other by a counterweight 10. When one conveyer starts up the pressure of the oil on the vanes 5 is sufficient to overcome the counterweight 10 of the switch mechanism and the switch operates to start up the following conveyer. Similarly, when one conveyer stops the counterweight operates the switch and stops the next conveyer.

Filed: 1937-10-07
Abstract: 503,909. Projecting lenticular colour films. I. G. FARBENINDUSTRIE AKT.- GES. Oct. 7, 1937, No. 27272. Convention date, Oct. 13, 1936. [Class 97 (i)] In the projection of lenticular colour films, with.means,for producing a spectrum in substitution for a light filter, one or more images of the light source are produced, from which second images are produced in the gate aperture, the width of the light beam being thereby reduced so as to improve the quality of the spectrum. As shown, a mirror S reflects a parallel beam from the light source L to a condenser C of such focal length that it would image the light source in the gate aperture B. Cylindrical lenses Z<1>, Z<2>, Z<3> behind it produce images D<1>, D<2>, D<3> of the light source, and cylindrical lenses Z<4>, Z<5>, Z<6> produce images in the gate aperture B from the images D<1>, D<2>, D<3>. A diffraction grating or direct-vision prism is arranged in front of the gate, and the arrangement is such that the three spectra produced do not overlap. The distance between the intermediate images is adjusted so that its ratio to the breadth of the lenticulations is equal to that of the distance separating the images and gate to the product of the focal length of the lenticulations and of the index of refraction of the film material; this results in coincidence of the images on the film of, for example, the sodium lines of the three spectra. The cylindrical lenses may be replaced by spherical lenses.

Title: Automatic stopping device for talking machines
IPC: G11B17/02
Filed: 1923-10-31
Abstract: 213,203. Gramophone Co., Ltd., (Victor Talking Machine Co.). Oct. 31, 1923. Starting and stopping; brakes.-Consists in an automatic stopping-device for a gramophone or the like, which is brought into operation, when the end of a record is reached, by a movement of the tone-arm or an equivalent part in the opposite direction to its normal direction of travel, such movement being caused solely by the record. The record is, for this purpose, preferably provided with an eccentric groove which the needle enters when it has traversed the sound track. In the construction shown, a pivoted brake-arm 20, 21 which is integral with a hand-operated releasing and' resetting lever 25, is held in the inoperative position by a detent 20 when a. finger 44 on the detent enters a notch in a part 18 of the brake. A spring 46 connects the detent and brake member together. On an arm 30, formed in one with the detent 29, which is pivoted at 38, is mounted a rack 70 coacting with which is a pawl 68 pivoted on a lever 60. The latter is pivoted on a stud 61, and has hinged thereto at 65 a forked part 63 which engages with a pin 64 depending from the tone-arm. The hinge enables the forked member to be turned up out of engagement with the pin 64 when desired. During the normal operation of the gramophone, the lever 60 is rotated bv the tone-arm in the anticlockwise direction, and the pawl 68 rides over the teeth of the rack 70, with which it is in contact. At the end of the playing of the record, the reproducing-needle enters an eccentric groove 82, whereupon the next revolution of the record effects a reverse movement of the tone-arm. This rotates the lever 60 clockwise to some extent, and so causes the pawl 68 to catch in the teeth of the rack, whereby the detent 29 is rocked on its pivot and the finger 44 is lifted out of engagement with the brakemember 18. The spring 46 then applies the brake to the turntable. An electric or other switch for the driving-motor of the machine may be actuated by the stop-member 18, in which case the friction-pad 21 would ordinarily be omitted.

Abstract: 269,080. Wharton, S. E. Nov. 3, 1926. Transparencies, travelling; optical - projection apparatus, applications of.-In optical-projection apparatus in which transparencies are moved in a closed conduit so as to pass in turn across the light beam, the front transparency 3 in an upper magazine 1 is moved sideways into the display position 56, then moved further in the same direction, then downwardly into a lower channel 7, and then returned to the front of a lower magazine 2, the rear transparency in the magazine 2 being concurrently transferred to the rear of the magazine 1, the transparencies in their movement being always parallel to one plane. The mechanism comprises a motor 14 which through an overload clutch 17, 18, 19 and reduction gearing 15 drives a shaft 24 carrying eccentric rollers 26, 47 engaging respectively pivoted levers 27 and 42. Lateral displacement of the lever 42 forces a sliding pusher 31 to the right by connecting members 43, 40, and allows the transparencies in the upper magazine 1 to be moved bodily forward by a rear spring. Entry of the roller 26 into a bay 46 on the lever 42 permits the member 31 to return suddenly under the influence of a spring 49 and transfer the front transparency into the display position 56. the transparency displaced is moved along and drops by gravity into the slideway 7, being assisted if necessary by a plunger 53 actuated by the upward movement of lever 27. A pusher 32 is drawn forward by a lost motion connecting rod 37 engaging a crank pin on the shaft 24, and forces a transparency under spring fingers 6 at the front of the lower magazine 2, the transparencies in which are thus moved bodily backwards. The rear transparency is next transferred upwardly to the rear of the magazine 1 by a pusher 30 connected by a pin 30<a> to the end of the lever 27. The roller 47 engages an extension 45 on the lever 42 and a stud 55 on the pusher 31 strikes a plunger 54 to complete the movement of the pusher 31, and a spring 35 serves to retract the pusher 32. The rear uprights confining the transparencies in the magazines 1, 2 may be adjustable to accommodate more or fewer transparencies, the pin 30<a> being changed for the new position of the pusher 30.
