Title: Improvements in or relating to apparatus for shearing animal skins
IPC: C14B1/24
Filed: 1934-03-26
Abstract: 436,147. Fur - shearing machines. PUYMBROECK, J. VAN, 158, Grande Rue au Bois, Brussels. March 26, 1934, No. 9387. [Class 76] A fur-shearing machine comprises a drum 22 over which the skin passes and on which it is supported while being sheared, which is provided with prong like projections on to which the skin is pressed as by smoothing rollers 20 and a pressure roller 51. The skins are conveyed to the roller 22 on their way to the shearing device 95 by sets of belts 1, 2 and 3, 4, between which the skin is compressed, and running over grooved pulleys. The belts 4 also pass round the drum 22. Blowing devices 11<1>, 12<1> deflect any fur projecting at the sides of the skin so that it is engaged by the rollers and smoothed down. A further blowing device 23 is arranged to discharge parallel with the surface of the drum to arrange the hairs of the fur so as to be properly cut. The pressing rollers 20 are loosely mounted on a common shaft 45 and rotate in jaws 38, pivoted on a fixed shaft 39 and are pressed towards the drum 22 by springs 40. Discs 46 fast on the shaft 45 carry pins 47 which engage holes 48 in the rollers 20 of diameter greater than the pins. Means are provided for automatic operation of the shearing device comprising a roller 51 which engages a fur skin passing round the drum 22 and causes movement of the bell-crank lever 52, 56 stressed by spring 57. The end of this lever contacts with a pin 78 on a spring stressed lever 75 having pins 74 engaging a groove in sleeve block 64 driven by gearing from the roller 22 and carrying clutch discs 66, 67 engageable with discs 62, 63 splined on the sleeve 61 on which the block 64 is mounted. A lever 80, 84 carries pins 79 engaging a groove on the clutch member 63 which carries pins 91 through which drive is imparted to a shaft 86 on which are mounted cams 85, 92 engaged respectively by the lever 84 and a roller 93 on the pivoted support 94 of the shearing device. The shaft 59 on which the sleeve 61 is freely mounted is fast to the gear 88 and to a cam 97 engaged by a lever 99 stressed by a spring 101, the cam being so contoured that the lever can effect a fractional rotation of the shaft. When a skin passes beneath the roller 51 the lever 56 moves to the right and allows the shift of the member 64 to the right to engage the clutch, members 67, 63 causing rotation of the shaft 87 and by motion of the cam 93 allowing the shearing device to move into contact with the skin. The cam 85 then comes into operation to shift the lever 84 and declutch the parts 63, 67. When the skin has passed from beneath the roller 51 the lever 56 moves to the left, the block 64 is moved to engage the clutch members 66, 62, the sleeve 61, shaft 59 and shaft 87 are rotated and the cam 93 lifts the cutter out of position. The cam 85 then raises the lever 84 and causes the declutching of the discs 62, 66. The lever 99 then returns the shaft 59 and the connected gearing to initial position.

Title: Improvements relating to delay mechanisms
IPC: H01H7/03
Filed: 1941-07-25
Abstract: 550,338. Delay mechanism. CHANCE BROS. & CO., Ltd., BERTENSHAW, N. W., and PARR, G. H. July 25, 1941, No. 9465. [Class 108 (iii)] In an adjustable delay action apparatus employing a dashpot or other delay mechanism, adjustment may be made by means of indicating mechanism in which a pair of relatively adjustable members are provided, one of which carries a single curve representing the force-time characteristics of the mechanism and the other a superposed frame of reference, one being non-adjustable and the other adjustable with the part of the delay mechanism by which adjustments are made. The upward movement of the cam f of a solenoid is retarded by a piston d working in a cylinder c until the lower port g is uncovered when resistance ceases. A small leakage orifice is provided in the piston d. The cylinder c can be adjusted vertically but is held against rotation and is pressed upwards by spring i. The two relatively adjustable members h carry respectively (a) the frame of reference t with force and time ordinates and abscissae and (b) the curve r representing the characteristics of the dashpot during its operative period. The member s is transparent and is fixed to the frame k while the cylindrical member s may be adjusted by rotation or longitudinal movement and is then secured in position by clamp q. To the upper part of member h is secured a spider n having cam surfaces o co-operating with similar surfaces on the dashpot cylinder c. When the member h is adjusted up and down the dashpot cylinder c, the piston d and the solenoid core f move with it since the piston and core are supported by shoulder p engaging the spider n. When member h is adjusted by rotation only, cylinder c is moved vertically by cams o thereby varying the length of the operative part of the stroke since piston d does not move The indicating apparatus thus facilitates the adjustment of the time and the force characteristics. The dashpot delay mechanism may be replaced by other delay mechanisms such as eddy current or air resistance.

Title: An improved process and apparatus for drying wood
IPC: F26B21/14
Filed: 1943-06-15
Abstract: 572,708. Drying wood. IRSA, G. 1. DE, and WOOD IMPREGNATION, Ltd. June 15, 1943, No. 9555. [Class 34 (ii)] Logs of wood 3 are dried in a closed chamber 1, heated by steam coils 2, by first covering the wood with water at a temperature up to 100‹C., the water being supplied from a tank 11 through a pipe 12 and valve 13, then withdrawing the water through a draining valve 27, and finally applying a vacuum to the chamber in two stages, viz., a vacuum of about 20 ins. of mercury, to effect extraction and evaporation of the free water in the wood, followed by a higher vacuum of 28 to 29 ins. of mercury to evaporate and remove moisture in the wood fibres. The vacuum is applied through a pipe 4, fitted with a control valve 5, which leads to a tank 6 also provided with steam heated coils 7 and connected by a conduit 8 and a water trap 9 with a conduit 10 leading to a vacuum pump (not shown). In the case of certain woods, e.g., walnut, which become discoloured when heated above 60‹C., after withdrawal of the heating water the chamber is filled with cold air which is supplied through a valve 31 and is heated by the coils 2 so that it expands and is forced into the wood to absorb the moisture, whereupon the air is released through a pipe 32 and the ordinary vacuum treatment commenced. In other cases wet or dry steam is admitted to the chamber during the vacuum stage. Ammonia gas may be added to the chamber to raise the temperature therein and assist evaporation, or, alternatively, carbonic acid gas may be applied at the end of the vacuum treatment to prevent re-absorption of moisture by the treated wood. In some cases quicklime may be added to neutralize any acids set free during the drying operation. A sump 14 is provided below the chamber to receive the water &c. from the valve 27, and this sump is connected to the tank 6 by a pipe 15 fitted with a lift pump 16. Further, the tank 6 and trap 9 have pipe outlets 28, 30 leading to a receiver for sap, from which such by-products as turpentine or wood alcohol may be recovered. Core and surface electrodes 19, 26 and a thermometer 22 are provided in one of the logs for determining the moisture content at the core and the surface as well as the internal temperature of this test log.
