Abstract: 620,769. Coiling slivers ; stop-motions. NICOLL, J. L. July 8, 1946, No. 20298. Convention date, July 9, 1945. [Classes 120 (ii) and 120 (iii)] Textile sliver is filled and compacted into a can or container by passing it from the delivery rollers of a carding preparing or like machine to the mouth of the can, through a stationary guiding and filling device bridging the gap between the delivery side of the rollers and the mouth of the can, including the re-entrant space between the rollers on their delivery side. The delivery rollers 1, 2 are arranged to give a downward throw to the sliver, and a bell-mouth 5, supported on a bracket 6, encloses the space between the rollers and the top of the can 3 including the re-entrant between the rollers 1 and 2. The sliver can may be supported on a platform 11, pivoted at 9, and counterbalanced by a weight 10a on a bellcrank 10 on the same pivot. The lower edge of the bell-mouth may be provided with steps, so, that progressive filling of the can causes the can to be forced down, until it finally falls out of the machine, for which purpose it may be weighted as at 18. This action may be used to operate a stop-motion. A lever may be provided whereby the can may be urged upward against the bell-mouth to force the sliver in the latter into the can prior to its removal from the machine.

Title: Improvements in or relating to typographical moulds
IPC: B41B11/52
Filed: 1926-08-17
Abstract: 272,717. Megley, H. J. Aug. 17, 1926. Moulds for type-bar-making machines.-Relates to the casting of type-bars, of the form shown in Figs. 20 and 21, having retention means for engagement with the type-carrier of a printing-machine. The mould 5, Fig. 1, is mounted on a mould-wheel 1 interchangeably with a mould 3 of the usual pattern. The mould-body comprises base and cap member 6, 7, Fig. 4, enclosing a cavity 14 in which the gate of the type-bar is cast, and separable jaws 22, 36, which are mounted on the mould-body, and form between them the mould for the type-bar proper. The jaws 22, 3& are provided with ribs 91, Fig. 19, to form retaining- grooves 134, Fig. 20, in the sides of the typebar and also with shoulders extending into close proximity to form the bottom of the type-bar, which is connected by a tapering portion 131 with the gate 15. The groove 136, in which the head 16 of the type-bar is cast, may be extended on one or both sides to give a wide type-face, as shown in Fig. 21. The mould-members 6, 7 are provided with slotted extensions 9, Fig. 3, which rest upon blocks 10, Fig. 1, on the mould-wheel, and are secured thereto by swivelled bolts 11. The outer face of the member 6 is recessed to receive an adjustable face-plate 19, Fig. 4, having a matrix-keeping ledge 26. The lower mould jaw 22 is guided by means of a flange 25 extending between the member 6 and the plate 19. The upper jaw 36 is guided on the member 7 by screws 41. The jaws 22, 36 have tapered extensions 45, 48, Fig. 3, which co-operate with sliding jaw-spreading member 55, Fig. 6, having wedge-shaped heads 56, which separate the jaws to permit of ejection of the type-bar. The members 55 are operated by projections 60 on the vice-frame, as the mould-wheel moves towards it. Displacement of the members 55 is normally prevented by the engagement of the upper edge of the jaw 22 in notches 77 in the members. The jaws are closed into casting position by spring agency, the closing movement acting to return the spreading-members 55 to normal position. The upper jaw is urged downwards by sliding members 23, 24 operated by springs 78, and the lower jaw is raised by springs 85 acting through sliding pins 89. The ends of the mould-cavitv between the jaws 22, 36 are formed by pairs of liners 93, 95, Fig. 3, the opposing faces of which bear knife-edges adapted to cut through any metal that lodges between them. The jaw extensions 45, 48 have knife-edges bearing on the parts 9 of the mould-body for the same purpose. The jaws 22, 36 have a knife-edge engagement with the adjacent surfaces of the mould-body, as shown in Fig. 19. To prevent separation of the jaws by the pressure of the molten metal, locking- means is provided in the form of pivoted members having wedge-shaped portions, which are caused by engagement with the vice-frame to engage bevelled surfaces 120, Fig. 3, on the flange 25 of the jaw 22. In a modification, the locking-members encage bevelled portions on both the lower and upper jaws.

[Class 140] Wood is coloured by treatment with gaseous ammonia in a closed receptacle in which a forced circulation is set up. The wood which need not be dried is piled on a truck which is placed in a cylindrical vessel 1 closed at each end by doors 2, secured by hinged bolts 3 and nuts 8. When released the doors are supported by cables 11 attached to an overhead trolley by which they may be swung away from the ends of the cylinder. The vessel 1 is heated by steam pipes 20 fed from inlet pipes 23, 24 and headers 21 and exhausted by outlets 25, 26. A perforated pipe 28 may be used to inject steam directly into the vessel. The forced circulation is induced by fans 30, 31, 32, 33 disposed in staggered relation at opposite sides of the vessel. Gaseous ammonia may be supplied by evaporating aqueous ammonia injected into the vessel or in an external evaporator or from anhydrous ammonia containers. After introduction of the wood the fans are started, steam is admitted to the radiators to raise the temperature to above 212‹ F. and below 350‹ F. and the vessel is partially evacuated to remove air and moisture, after which the ammonia is introduced. Drying of the wood during colouring is controlled by relief valves which may be set so that the operation may proceed at a pressure below or above that normally developed by the ammonia and water vapour liberated from the wood at the temperature employed. For example, compressed air may be introduced to increase the pressure at any stage of the process.

Abstract: 460,274. Feeding and drinking appliances for infants and animals. HUGHES, C., and HUGHES, G. July 23, 1935, Nos. 20864/35 and 7564 /36. [Class 5 (ii)] [Also in Group XVII] A feeding bottle for animals is provided with a one way device to prevent the return of liquid from the teat to the bottle. Provision is made for admission of air to the bottle either by a separate valve or by air passages in the one-way device. In one form, Fig. 1, a plug 6 is inserted in the neck of a bottle with one or more passages 9 controlled by a rubber or like disc valve 10. An air inlet of usual construction is provided at the other end of the bottle. Food is fed by gravity to the teat 3. When the teat is contracted food cannot return to the bottle past the valve 10. If the baby ceases to suck the resistance of the valve 10 stops the flow of food. In a modification, Fig. 6, an additional valve 14 is used and side passages 15, 16 are added. Until the teat is contracted food will not flow. Two actions are produced, one opening the air valve 16 to the upper chamber, and one allowing food to flow by pressure of the teat. When the teat enlarges to its natural size two actions also ensue. Air enters the teat and liquid descends under gravity into the teat chamber and not until the teat is collapsed is food fed to the infant by pressure of the lips. Flow stops if infant falls asleep. In another modification, Fig. 12, slits 17, 18 are formed in a rubber body 19 to place into communication moulded passages 9 with teat and bottle chambers and operate as separately made valves. In another modification, Fig. 6, a fine aperture 20 or a similar one 21, Fig. 13 will allow passage of air but not of milk.
