Title: Improvements in and connected with pegs for loom shuttles
IPC: D03J5/08
Filed: 1919-08-25
Abstract: 155,874. Smith, N. Aug. 25, 1919. Shuttles.-A loom shuttle peg consists of two parts a, a<1>, the free ends of which are brazed together or similarly connected, while the pivoted ends are curved, as shown in plan in Fig. 1, so that they are in contact near the pivot d, and separate at their extremities. As the peg is pressed down into the shuttle, these extremities are forced together by the inturned sides of the box b, shown inverted in Fig. 3, in which the peg is pivoted, and the parts a, a<1> are expanded so as to hold the cop on them securely. The cop is prevented from creeping backwards or forwards on the peg by making each of the parts a, a<1> of a strip of metal which, as regards one-half of its length is flattened in one plane, and, as regards the other half, is flattened in a plane at right-angles, the sections being as shown in Fig. 4. There are thus formed midway along the length of the peg two sets of shoulders which prevent the movement of the cop on the peg. The peg is held in position by a stop pin e, Fig. 3, and by interengaging projections and recesses b<1>, b<11> on the box and the extremities of the peg.

Title: Improvements relating to vacuum brake cylinders for vehicle brakes
IPC: F16D65/28
Filed: 1953-07-28
Abstract: 738,069. Pistons. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., LEECH, K. H., SHATTOCK, C. F. B., and SIMMONS, A. W. July 7, 1954 [July 28, 1953], No. 20922/53. Class 122 (1). The diaphragm piston in a vacuum brake for a vehicle is connected to the piston rod 17 by means of a nut 10 engaging screw threads on the piston rod and housed in the diaphragm support 12 to which the diaphragm (not shown) is clamped at its inner periphery, the outer periphery of the diaphragm being clamped to the base 13 of the cylinder and the positioned piston rod being rotatable relatively to the piston, without screwing up or unscrewing the nut 10, to facilitate attachment of the connecting rod to the brake mechanism. The piston is illustrated in its inoperative position, with the support 12 resting against a boss 11 on the base 13. A rib 2 is formed on a cover 1 for the housing 3 receiving the nut 10 or on the nut and is engaged with a recess in the other member upon axial displacement of the nut prior to attaching or detaching the piston rod, the co-operating rib and recess preventing rotation of the nut. This effect is produced in the construction of Fig. 2, without axial displacement of the nut, by a projection 26 on one of the parts and a recess 27 in the other part which is large enough to allow a predetermined degree of relative rotation between the parts. In a further construction, a radial projection on the nut may engage an elongated arcuate recess in the support 12 to permit the relative rotation between the parts. The torque on the piston during screwing the piston rod into the nut 10 may be reacted by co-operation between a projection on the underside of the support 12 and a recess or projection on the inside of the base of the cylinder when the piston is in its inoperative position.

Title: Improvements in consistency controlling devices
IPC: D21F1/08
Filed: 1929-07-08
Abstract: 330,166. Meyers, S. E., and Merritt, E. H. May 7, 1929, [Convention date]. Pulp, regulating consistency of; alarm and indicating apparatus.-The consistency of fluid suspensions, such as wood pulp stock, is automatically regulated by the addition of a consistency modifying agent e.g. water. A paddle, arranged to rotate in the fluid suspension, is driven through a train of gears; the train includes a movable member which moves in response to the driving effort required to rotate the paddle. This movable member actuates a controlling device e.g. a valve, which directly controls the utilisation of the consistency modifying agent. In Figs. 1 and 2, 10 is a reservoir or stuff box fed through the pipe 11. A partition 12 ensures the maintenance of a constant head. The rotating element 16 has concave blades 58, which carry round some of the solid particles. This is driven by the electric motor 17 through the worm 41 and worm wheel 40, the regulating device (shown in Fig. 3), the shaft 26, and bevels 33 and 34. The form of regulating device shown in Fig. 3 consists of a wheel 23, driven by the electric motor, coupled by means of a belt or chain 24 to the wheel 22 which is geared to the paddle. The belt passes round a pulley 43 which can move vertically. If the consistency of the paper pulp increases, more power is required to drive the paddle 16, the tension in the belt 24 increases and the sheave 25 is raised against the spring 47. This lifts the valve 51 off its seating and allows water to flow through the pipe 21 and into the bulk of the suspension, so rectifying the increase. Other means for operating the valve 19 may be employed such as an arrangement of differential gearing in which the shaft 87, Fig. 7, is driven and the shaft 83 is geared to the paddle 16. When the torque necessary to rotate the paddle becomes excessive, the yoke 85 turns slightly and operates the plunger 91 which controls the valve 19. In a third arrangement utilising planetary gears, the wheel 102, Fig. 8, is driven and transmits the motion to the wheel 96 through gears 99 and 99<1>. The outer wheel 96 is geared to the paddle. When the resistance to the motion of the paddle increases, the arm 100 turns, and operates the valve 105. An indicating device may be operated by the movement of the tension sheave 25. A mercury switch, adapted to light different coloured .lamps for different positions of the valve is shown in Fig. 5. The insulating tube 62 is moved about the pivot 71 by means of the arm 72 attached to the tension sheave. A globule of mercury 64 makes contact between the wire 65 and the wires 63, 63<1>, 63<11>, which are attached to flexible leads. Thus for different positions of the tension sheave 25, the tube 62 is tilted by different amounts, and various coloured electric lamps illuminated. The device is applicable to fluid suspensions which are treated under pressure, and to the control of consistency in other arts, for example, the consistency of clay compounds, glues, and the like.

Abstract: 349,355. Ventilating systems and apparatus. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. July 11, 1930, No. 21013. Convention date, July 19, 1929. [Class 137.] A plant for washing and controlling the humidity and temperature of air in enclosed spaces uses the air to be conditioned as refrigerating medium in an air refrigerating machine when cold air is required in summer. Air is drawn from a room 1 mixed with fresh air to a regulable extent at 4 and normally is sprayed at 5 with water brought to a predetermined temperature at 6; any water entrained is separated at 8 and the air is drawn by a fan 10 through a heater 9 into the room. When cold air is required, the flap 27 is closed and air passes through the air fan compressor 12 and after removal of heat of compression by a cold water spray 5, the air expands through a turbine 13 and returns to the room. Apparatus for the occasional cooling of air comprising a refrigerator with a steam compresser, a condenser, and an evaporator using a medium such as ammonia or carbon dioxide is also described.

Title: Improvements relating to actuating mechanism for epicyclic change-speed gearing
IPC: F16H61/02
Filed: 1933-07-26
Abstract: 423,182. Variable speed gearing. DAIMLER CO., Ltd., Coventry, and OLIVER, A. V., Merrick Lodge, St. Nicholas Street, Coventry. July 26, 1933, No. 21081. [Class 80 (ii)] In actuating mechanism for epicyclic gearing of the kind in which brakes are selectively connected to a rocking bus-bar, a single hydraulic cylinder 5 and piston 4 act upon the bus-bar 1, and the hydraulic pressure is applied and relieved by a ram 7 of small diameter compared with the piston, the ram being actuated by a pedal or the like. To disengage any brake, starting from the engaged position shown, a shaft 11 is rocked by linkwork from the pedal, so that a projection 13 moves downwardly. Owing to the high liquid pressure in the cylinder 5, the strut 15 is held, and the lever 14 rocks about its upper end. The lever 14 is jointed to a lever 16, which rocks about the end 19 of the stem of a relief valve 6 held closed by a spring 8. The ram 7 is thus withdrawn against its spring 9 and the pressure within the cylinder 5 reduced so that the relief valve 6 is opened, and liquid from the cylinder 5 escapes into the reservoir 18, while the strut 15 can now move downwardly, compressing the spring 10 and disengaging the brake. On releasing the pedal, after selecting a fresh brake, the spring 10, through the strut 15 and lever 14, returns the shaft 11 towards the position shown and produces initial engagement of the selected brake ; the liquid runs back by gravity from the reservoir 18 ; the valve 6 closes ; and finally the ram 7 is thrust into the cylinder by its spring to apply the brake fully. The springs 8, 9, 10 are so designed as to permit this sequence of operations. In a modification, the lever 14 is fulcrummed on the strut 15 and the lever 16 on the head of the ram 7. In a further modification, the valve 6 is a sleeve valve and its stem forms the ram. According to the Provisional Specification, the return movement of the shaft 11 may be retarded by a dash-pot to prevent premature operation of the ram 7.

Abstract: 464,558. Grease guns. TECALEMIT, Ltd. July 30, 1936, No. 21153. Convention date, Aug. 1, 1935. [Classes 102 (i) and 102 (ii)] Relates to means for filling the reservoircylinder 3 of a grease gun from a container 1, and consists in the provision of a positive connection, e.g. a bayonet or screw joint, between the cylinder 3 and the follower 23 of the container 1. As shown the cylinder 3 which supplies the h.p. cylinder of the grease gun, is provided with a,piston 15 acted on by a spring 19. When filling the grease gun the cap 17 is unscrewed and the piston 15 is retracted by means of the rod 9, which has a pin 13 for engaging the piston. The pin 13 can be engaged with a lug 4 on the piston, if it is desired to push the latter forward. The invention is also applicable to a grease gun in which the piston 15 is forced forward by means of compressed air admitted to the cylinder 3. In this case the rod 9 may be formed with a forward prolongation which acts as the h.p. plunger. During lubricating the plunger is pressed forward by means of the handle 6 and is retracted bv air pressure acting on a piston moving in the cylinder 27. An adapter is provided between the cylinder 3 and the follower 23 in order that the prolongation of the rod 9 may not foul the container. U.S.A. Specification 1,981,495 is referred to.

Abstract: 813,685. Haymaking. WILLANS, K. W. July 20, 1956 [July 22, 1955], No. 21255/55, Class 6(3). Haymaking machinery comprises a tractor-drawn frame 1 supporting a four-legged drying frame 7 surrounded on threee sids by a vertical screen 19, together with an elevator 5 located so as to discharge cut grass on to the drying frame. The drying frame comprises two rectangular hurdles each consisting of a pair of posts 10 spaced apart by four horizontal spars 11, the hurdles being locked together at their upper ends so that the frame is an inverted V-shape in section. The lower ends of the posts 10 are supported in channel members 12 pivotally mounted at 13 on the rear of the frame 1, a weight 14 being provided to counterbalance pivotal movement of the channel members. The two rear posts 10 of the drying frame are located in notches 15 in the channel members by means of -pins 16 driven transversely through the posts (see Fig. 3) To discharge the loaded drying frame from the frame 1, a manually operated catch is released to allow the channel members 12 to assume the position 12a with the rear legs of the drying frame in contact with the ground, and the frame 1 is moved forwards, whereupon the front legs of the drying frame slide along the channel members and the frame is discharged through the open side of the screen 19. The notch and pin arrangement for holding the rear legs of the drying frame in position on the channel members 12 may be replaced by the hook and slot arrangement illustrated in Fig. 5. Even distribution of the grass on the drying frame may be attained either manually by an operator standing on a platform 20, or mechanically by providing for the drying frame to be mounted on a turntable or to be tiltable, or by providing movable deflectors. Further, the supports for the legs of the drying frame may take the form of individual sockets and may be moveable relative to each other to allow variation of the relative inclination of the hurdles. The elevator and drying frame may be carried by separate interconnected wheeled frames. As described in the Provisional Specification the channel members 12 may be lined with conveyers to assist in discharging the loaded drying frame. Specification 751,512 is referred to.

Title: Improvements in adjustable presser pads for use on the printing heads of addressing machines and like printing machines
IPC: B41L47/42
Filed: 1943-12-20
Abstract: 568,497. Addressing machines. ADREMA, Ltd., and KERR, R. L. Dec. 20, 1943, No. 21320. [Class 100 (ii)] An addressing-machine of the kind in which an impression member carried by an oscillating head 1 prints in connection with a printing- plate moved across an anvil, is constructed with a presser pad which is adjustably mounted so as to co-operate with two, three, or more lines of a variable printing matter by mounting the pad 4, Fig. 6, on a plate 8 attached to a support 5, Fig. 2, adapted to be adjusted on a base-plate 3 connected to a plate 2 secured to the head 1 by a universal connection. The plate 8 of the support 5 is connected to blocks 6, 7 with undercut grooves 9 which embrace the edges of the plate 3, and ratchet teeth 10 on these blocks are engaged by pawls on a bar 13 which can rock about its centre under the action of an arm 14 actuated by a finger piece 24, or actuated electromagnetically. The support 5 is acted upon by a pair of springs arranged in bores 25 in the plate 3, and by means of a knob 34 the support 5 can be moved to its forward position against the action of the springs, and in this position a recess 43 in the slide is guided by a projection 42 on a support 39 which is fitted with a presser pad for printing in connection with a fixed printing-plate common to all printing operations. The support 39 is connected to blocks 6a, 7a. From this forward position of the support 5, it can be returned to its rear position, in which the pad 4 co-operates with the minimum number of lines of the address plates, by actuation of the bar 13 which causes an escapement-like action permitting the support to return under action of the springs in the bores 25. The plate 8 is secured to the blocks 6, 7 by screws 32, 33, or as shown in Fig. 6, by screws 32 with bevelled edges engaging bevelled edges of the plate 8, the screws 32 being carried by a spring-pressed member. The blocks 6a, 7a normally are drawn by a spring against stops 40, and the extreme position of the support 39 is limited by a stop 41 on the base-plate 3.
