Title: Leaf tobacco shredding machines

Filed: 1956-08-10
Abstract: 798,713. Cutting tobacco. S.A.S.I.B. SOC. PER AZIONI SCIPIONE INNOCENTIBOLOGNA. Aug. 10, 1956 [Aug. 11, 1955], No. 24629/56. Class 5(1). [Also in Group XXIII]  In shredding tobacco issuing from a mouthpiece by rotary cutters 7 which are continuously sharpened by a grinding cylinder 17 and in which the cutter rotor 5 and the grinder 17 is continuously moved towards the mouthpiece to take up grinding wear, undue advance of the rotor is declutched by electrical contacts on rotor and mouthpiece, and after a short period when the contacts are broken again the rotor and drive is clutched in again to resume the advance. Thegrinder 17, Fig. 2, pivoted at 128 rests by gravity on the cutters and is dressed by diamond 27 lowered into contact by a handle 37. In starting the machine from position, Fig. 6, in which the clutch lever 14 is neutral and roller 154 clear of cam 57, switch 75 open, electromagnet de-energized and pawl 47 engaged in the stop ratchet wheel 44 and pawl 47 engaged with ratchet wheel 45, the starting is as follows, Switch 75 is closed to start rotation of rotor 5, to energise electromagnet 52 which pulls pawl 46 from 44 and permits rotation of shaft 42 clockwise, and the rotor is advanced towards the mouthpiece by handwheel 43. This advance is stopped when the revolving knives 7 touch the contact 66 thus de-energising 52 and allowing pawl 46 to engage wheel 44. To get automatic feed in by the rotor the conveyer bands are first started by hand moving clutch lever 14 to position, Fig. 7, where the sector 57 is disengaged from bell crank 54 where end roller 154 engages cam 56 and so rocks the shaft 42. As long as the knives 7 do not touch the contact 66, 52 is energised and disengages pawl 46 from ratchet 44, permitting shaft 42 to revolve clockwise and the rotor to advance. When the knives 6 touch contact 66 to energise 52 and lock the ratchet 44 of pawl 46 whose tail 61 pushes the driving pawl 59 out of contact with the teeth of the feed wheel 45, Fig. 8 Roller 154 however remains engaged with cam 56 which rocks lever 54 and stops advance of the rotor. The grinder however continues to advance to sharpen the knives 7 which when thus ground down cease to make contact with 66 whereby electro-magnet is again energised to start the step by step advance of the rotor sets knives 7 towards the mouthpiece. When the knives are worn out and need adjusting outwards the cam 64, Fig. 8 (not shown) opens switch 65 stopping current to main motor thus stopping the machine. A mechanical safety stop is also provided whereby an abutment 78 stops lever 76 to lift lever 54 out of contact with cam 56 thus stopping the advance of the rotor. U.S.A. Specification 2,819,746 is referred to.

Filed: 1927-09-21
Abstract: 297,219. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). Sept. 21, 1927. Peeding webs.-Means for controlling the tension of a web fed to a printing-machine consists of a friction device in the form of a strap or straps engaging the surface of the web roll and connected to a weight or other energy storing device supported by the running web, so that variations in the tension of the running web cause adjustment of the braking effect of the strap on the web roll. Means such as counterbalance weights may be provided for varying the pressure of the strap on the roll. In the construction shown in Fig. 1, the web 11 from the roller 10 passes over fixed guide rollers 12, 14<1> and an adjustable tension roller 15 mounted on springs 20, and is looped at 32 to support a floating roller 31 mounted m bearing blocks 34 carried by a pair of chains 29, the other ends of which are attached to a floating cross-bar 28. A narrow strap 23 is attached at one end to the cross-bar 28 and at the other end to a fixed bar 24, and passes over guide rollers 25, 26 so that it laps over about half the circumference of a full roll. Counterbalance weights 46 are connected to the chains. The bearing blocks 34 may slide on vertical guide rods 35. The chains pass over sprockets on a shaft 42, which may be provided with means, such as a hand-wheel and a detent pawl 49 and ratchet-wheel 48, for rotating it to raise the roller 31 and slacken the strap when a new roll is being placed in position. In another construction, shown in Fig. 6, three narrow straps 51 are attached at the lower end through springs 55 to a fixed bar 54, and are wound at the upper end op drums on a shaft 57 connected by chain gearing 59 to an upper shaft 79, over which and a lower shaft 72 run endless chains 65 carrying the floating roller 73 and the counterweights 69. The shaft 79 may have a squared end to receive a handle for rotation to slacken the straps.

Abstract: 868,344. Typewriters. OLIVETTI & C. S.p.A., ING. C. July 21, 1959 [July 26, 1958], No. 24960/59. Class 100(4) A power-operated type-action comprises a type-lever 27 having a heel 26 rocked through a predetermined angle A and connected by link 25 to an individual power actuator 14 mounted for substantially rectilinear reciprocation according to a direction substantially perpendicular to the bisector B of said angle and is provided with an element 24 which is variably formed according to the angular position of its associated type-lever so that a constant force is imparted to the type bars irrespective of their angular position. When a key-lever 2 is depressed, a push rod 8 pin and slotted thereto, engages and trips a latch 12 attached to the power actuator 14. A pawl 15 is thus released and is engaged by a metallic blade 51 resiliently set in a rubber covered power shaft 50,49. This causes actuator 14 to move to the left and effect a type action. Towards the end of the movement to the left the pawl 15 is relatched by the engagement of surfaces 32 and 33. The right-hand end of the actuator 36 engages a bail 37 supported on levers 38, and end 40 of lever 38 causes a lever 42 and a universal bar 44 to move into position to prevent a second pawl 15 from engaging the power roller. If a key is held depressed, repeat action does not occur because the return of the actuator 14 to the right causes the end 11 of the latch 12 to pivot the push rod 8 clockwise; it does not therefore, again release the latch 12 and pawl 15.

Electrically vibrated instruments; instruments with sonorous plates, percussive; keyboard stringed instruments.-Electromagnetic hammers b, acting with a high rate of vibration on strings a, or on diaphragms or wooden resonant members, are operated by current rendered intermittent by means such as a buzzer A in a separate circuit. Regulation of the amplitude of the hammer is obtained by adjustment of limit stops L, w, and the normal position of the hammer is adjusted by means of its screw mounting at q, by a screw h, or by turning the whole unit about a pivot u by means of a screw t. Current strength is adjusted by a rheostat i<1>. In a modification (Fig. 3, not shown) the intermittent contact u<2> may be provided with its own electromagnet in series with the buzzer magnet g<1>. As shown in Fig. 4, with the circuit + to -V, the interruptions produced by a second buzzer A<2> are superposed on those of the first, producing a combination tone or tremolo. Fig. 5 shows a damper a<111> which is withdrawn from the string e<111> by a solenoid b<111> on actuation of the key. The frequency of a hammer may be a multiple of the frequencies of the tuned strings. The frequency producer may be housed in a separate container; noise-producing parts of the apparatus may be arranged in a vacuum.
