Title: A towelling dispensing device
IPC: A47K10/36
Filed: 1946-09-16
Abstract: 625,689. Towelling dispensers. WOOSTER, P. A. Sept. 16, 1946, No. 27743. [Class 18] The dispensing roller 21 of a towelling dispenser is rotated by a handle 28 through worm and wheel gearing 29, 32 so arranged that it is necessary to rotate the handle a number of times to effect one revolution of the roller. As shown towelling from a supply roll 20 supported between two side plates 12, is led between the dispensing roller 21 and a pinch roller 22 which is urged towards the dispensing roller by springs 37 attached to its ends. The gearing is disposed in a casing 25 on the outside of one of the side plates 12, the trunnion of the dispensing roller extending through the side plate 12 to support the gear wheel 32 within the casing and the handle, on which is positioned the worm 29, being supported in bearings in the casing. The worm is rotatable on the handle spindle and is reduced at one end to abut with a collar 30 which is pinned to rotate with the handle spindle. A coil spring 31 is supported around the collar and reduced portion of the worm, the arrangement being that when the handle is rotated in one direction the spring tends to tighten and grip the shanks of the collar and worm to rotate the dispensing roller, but when the handle is rotated in the reverse direction the coils of the spring tend to open and the spring slips over the shanks, thereby preventing reverse rotation of the dispensing roller. In addition, a pawl 34 is adapted to engage the gear wheel 32 to prevent reverse rotation of the dispensing roller. A cover 17 encloses the whole of the side plates and gearing casing.

Abstract: 986,454. Cigarette-making machines. K. KÍRBER. July 20, 1962, No. 28003/62. Heading A2C. Apparatus for supplying severed sheets 13 of material from a continuous strip 3 to a perforated conveyer drum 9 to which suction is supplied via passage 10 from a suction chamber 19 connected to a source of suction by a duct 17, is characterized in that the cross-section of part of the suction chamber 19 is reduced so as to form two sub-chambers. The two sub-chambers A and B may be formed by a block 18 or by making the hole of chamber B of reduced cross-section (Fig. 2, not shown). The division between the two chambers is situated adjacent the cutter 12 which cuts the strip 3, e.g. paper for forming connector strips for groups G of cigarettes and mouthpieces, into sheets 13. Variation in suction in the chamber B, due to faulty or missing sheets 13, is thus substantially prevented from affecting suction in the chamber A which remains strong enough to hold the strip 3 against the drum 9. Specification 768,489 is referred to.

Abstract: 280,876. Zellstofffabrik Waldhof, and Haas, R. Nov. 20, 1926, [Convention date]. Testing viscosity of liquids. - The viscosity or consistency of a liquid is measured by impart. ing motion to bodies of suitable form, immersed in the liquid, and using the resistance experienced to actuate indicating devices or to initiate regulating operations. The propeller m Fig. 1, dips into a vat containing fibrous pulp 'and is driven from a shaft r through an epicylic gear p, s, q the carrier for the planet wheels of which is held by adjustable springs t Fig. 2 which balance the torque. A pointer u on the carrier moves over a scale indicating consistency and an arm z is adapted to close a contact u to cause an audible signal to be emitted and the admission valve for diluent to be closed. In a further modification, discs on a shaft dip into the liquid and the motor is supplied with current from a battery in circuit with which is a solenoid and ammeter. When the viscosity varies, the current supplied will vary and the armature of the solenoid will be moved against the influence of a spring to make certain contacts in a regulating circuit. The Specification as open to inspection under Seat. 91 (3) (a) comprises also the form shown in Fig. 1 (Cancelled) in which a propeller a depends from a balanced lever f into the stream of liquid and is driven from a motor b at constant speed through bevel gearing c. The end of the lever is connected by a cord h and arm i to a valve e. The weight l is adjusted so that the pointer k indicates zero on the scale when the liquid is at the correct degree of concentration. If the concentration increases, the increased pull of the propeller on the lever causes the latter to move downward and the valve e to open further to admit more diluent to the stream of liquid to restore the desired consistency. This subjectmatter does not appear in the Specification as accepted.
