Title: Improvements in or relating to paper feeding devices
Inventor: DAVIS ROGER ARTHUR
Filed: 1957-05-06
Abstract: 830,526. Typewriters &c. INTERNATIONAL COMPUTERS & TABULATORS Ltd. April 14, 1958 [May 6, 1957], No. 14406/57. Class 100(4) A paper feeding device comprises pin wheels 21 or other feeding means driven by an output shaft 6 from a continuously rotating drive shaft 2 through a friction clutch and provided with selectively operable stop means declutch the drive in two or more positions and means to retain the output shaft against rotation in one direction and locating means preventing rotation in the other direction. The friction clutch comprises bushes 5, 7 within a drum 10 normally rotating together by the action of a spring 8 around the bushes. The drive is stopped by the engagement of a selected lug 12 by a stop member 13 unlatched by an electromagnet 29, which holds the drum 10 and allows the spring 8 to unwind sufficiently to unclutch the bushes 5, 7. Forward rotation of the shaft 6 is prevented by engagement of a projection 14 of the drum 10 with a slot 15 in the bush 7 while backward rotation is prevented by locating means comprising a pawl 17 engaging a ratchet wheel 16. When the drum 10 is stopped the drive continues under the force of the spring 8 sufficiently to allow engagement of a pawl 17 to accurately position the paper. The feed is restarted by energizing an electromagnet 28 which withdraws the stop member 13 and allows it to be re-latched. The central part of the shaft 6 is reduced to form a torsion rod and is enclosed in a tube 31 which normally provides a rigid drive by lug 38 of a sleeve member 32 engaging one side of slots 39 of a driving collar 40 of the shaft 6. A sudden stopping of the paper feed causes the torsion rod part to twist while the inertia of the paper feed is absorbed, when the bush 7 is stopped, by continued rotation of the right hand end of the shaft 6 twisting it and turning the tube 31 against the frictional engagement of its collar 32 with a conical part 35 under the force of a spring 36 while the lugs 38 move in the. slot 39 made wide enough to allow this.

Title: Papermakers wet felt, method and apparatus for dewatering wet web using such felt
IPC: D04H13/00
Filed: 1964-04-08
Abstract: 1,059,983. Laminates. HUYCK CORPORATION. April 8, 1964 [April 16, 1963], No. 14603/64. Heading B5N. [Also in Divisions D1 and D2] A papermaker's felt for the wet press section of a papermaking machine comprises a permeable base layer in the form of an endless belt the material of the base layer being of relatively low compressibility under normal wet press pressures and providing a substantial voidage for the reception of water constituted by passageways in the base layer; a permeable facing layer coextensive with the base layer is united to it and is of material which is relatively easily compressed and which has passageways of relatively small size compared with the base layer. The base layer may be woven as an endless belt and may include yarns of polyamides, alone or with cotton, and polyesters. The facing layer may be a carded or Garnetted fibrous web which may be needled to the base fabric or needled and then united adhesively thereto and comprises wool fibres or mixtures thereof with synthetic fibres, such as polyamides, polyesters or acrylic fibres. The degree of compressibility of the base layer is dependent upon the type of weave, the yarn count and twist and may be reduced by suitable aftertreatment. A nylon base fabric, for example, may be treated with melamine formaldehyde and then heat set. Alternatively such a fabric may be treated in a first stage with phenolic formaldehyde and in a second stage with an aldehyde donor with heat setting. A nylon and cotton fabric may be impregnated with a resorcinol formaldehyde and melamine formaldehyde to improve its resistance to compression. In order to prevent rewetting of the facing layer and possibly also of the web of paper after passage through the nip of the press rolls the fibres of the facing layer may be treated to provide water repellancy. Alternatively a barrier layer, which may be the adhesive, may be provided between the base and facing layers to restrict the return movement of water from the base to the facing layer after the nip pressure is released. A suitable adhesive referred to for uniting wool fibres to a base layer containing nylon with or without cotton is an adhesive of the family of phenol blocked isocyanate resins. These substances may also be used as a barrier layer where the facing and base layers are to be united by needling. The base layer may be formed to retain water or to allow its passage therethrough by suitably determining the sizes of the passages in the base fabric.

Title: Improvements in coin freed mechanism
IPC: G07F15/02
Filed: 1929-05-14
Abstract: 331,049. Bingham, J. H., and Glover & Co., Ltd., G. May 14, 1929. Coin action, mechanical-connection and multiple-coin; coin-slit closing-devices. - Means are provided for preventing the presence of more than one coin at a time in the coin pocket of coinfreed mechanism of the kind comprising a coin pocket which receives coins of different sizes and retains each coin in an appropriate position according to its size, so that coins of each size engage a corresponding wheel and form a driving- connection between the pocket and such wheels, mechanism of this kind being applicable to gas meters to set forward the quantity mechanism in accordance with the value of the coin inserted. The coin pocket comprising two spaced plates 9, 10, Fig. 7, is mounted by radial arms 6<a>, Fig. 3, on a spindle 6 on which are loosely mounted coin wheels 7 for engagement by a coin, according to its size, in the pocket. The wheels 7 are secured to wheels 5 of different sizes which rotate through gearing a quantity wheel 3, an amount proportional to the value of the coin inserted. A coin is supported in the pocket between a wheel 7 and a pivoted gate 11, so that it is opposite a hole 18 or 18a formed in the walls 9, 10. A swinging bar 19, pivoted at 20 to the pocket, is provided with pins 21, 22 which enter the holes. A coin, however, rocks the bar to withdraw the pins and the bar is retained in its rocked position, until the coin is discharged, with a stop plate 23 at its upper end projecting across the coin entry slot, thereby presenting more than one coin from being inserted into the pocket at a time. As a further or alternative means for preventing the insertion of a second coin before the discharge of the first, a bracket 1 supporting the mechanism is provided with a shelf 24 on to which the coin first falls and prevents the entrance of a second coin. When the pocket is rotated, the coin is moved off the shelf and descends into engagement with a wheel 7. The shelf 24 is opposite the hole 18 and, with a second projection opposite the hole 18<a>, prevents the pocket from being returned to coin receiving position. The coin pocket is provided with a spring which encounters a fixed stop to retard the movement of the pocket and allow time for a coin to descend from the shelf 24 to its driving position. The spindle 6 is rotated by a handle 13, Fig. 1, having a guard plate 17 to close the slit 16 when the handle is moved. A cut-off plate 33 pivoted at 34 to the casing has a pin 35 extending through a slot 36 to engage a recess 37 in the guard plate 17. The initial movement of the handle causes the plate 33 to move more quickly and cover the coin slit 16. Coin-discharging mechanism; price-changing mechanism. - A projection 29 on the gate 11 encounters a fixed stop to move the gate aside and allow the coins to fall out to a money-box. The stop is arranged on an adjustable pricechanging abutment 31, provided with a spring 32 to cushion the impact of the coin-pocket.
