Patent GB-570180-A (GB)
Title: Improvements in or relating to knitting machines and knitted fabric
IPC: D04B9/18
Filed: 1943-06-02
Abstract: 570,180. Knitting. COLE, B. T., and COLE, J. M. June 2, 1943, Nos. 8805 and 13653. [Class 74 (ii)] In knitting a fabric by rotary knitting upon a circular machine in which a thread, such as a splicing thread, is fed to and knitted by a variable number of the needles and is excluded from the remainder of the needle circle so that normally it would form a float, a predetermined length of float thread commensurate with the number of needles is drawn from the feeder and is knitted up by the needles at the next course. A fabric is thus formed having an area knitted with inclined selvedge edges of a weft thread that is knitted in successive courses. The splicing or other thread which is so knitted may be fed directly by the feeder at alternate courses and the float thread may be knitted at the intervening courses. Alternatively, thread fed directly from the feeder may be knitted together with the float thread. The device for drawing thread from the feeder 111a comprises a hook between 17 which engages the thread between the feeder and the last splicing needle 12b. The hook 17 is formed at one end of a rod 117 attached at the other end to a member 26. The member 26 and hook 17 are moved radially away from the cylinder to take thread from the feeder by a lever 25, having a pivoted catch member 75 which is released from the member 26 when a detent member 77 mounted upon the lever 25 engages a stop 22. Upon release from the catch member 75, the member 26 and hook 17 are drawn forward as the needles knit up the thread. The stop 22 which determines the length of movement of the hook 17 and therefore the amount of float available for knitting at the next course is adjustable by a lever 23 under control of a cam 41 which also determines the period of activity of the thread feeder. Alternatively, the stop may be adjusted manually. When the feeder supplies thread directly to the needles during every second revolution of the needle cylinder, the feeder 111a is lowered at the outside of the needle circle to feed the thread to the needles and at the inside of the needle circle to introduce the float to the needles. To enable the feeder to supply thread directly at each revolution, it is lowered only at the outside of the needle circle, and a finger or depressor is lowered within the needle circle to introduce the float to the needles simultaneously with the lowering of the feeder. A member 19 is mounted within the needle circle to support the float extending from the feeder or finger to the hook 17. Specifications 532,520 and 532,586 are referred to.

Title: Improvements in and relating to pencil holders or cases
IPC: B43K21/08
Filed: 1928-03-23
Abstract: 307,227. Bedford, P. L., and Mordan & Co., Ltd., S. March 23, 1928. Pencil holders.-A pencil holder having projecting and retracting mechanism for the lead consists of an outer sheath and a frictionallyheld inner member carrying the lead-projecting mechanism, the inner member being also provided with a tube at one end forming a continuation of the bore in the outer sheath so as to accommodate and protect the lead during fitting or removal of the outer sheath. The sheath comprises a tube a having a point formed integral with or attached to it, and the bore is formed with a number of shoulders forming bearings for parts of the projecting-mechanism. The bore of the point is of the same diameter as the lead so that the lead is supported against breakage. The inner mechanism is enclosed in a slit tube c, and comprises a screw-threaded tube d, a longitudinally-slotted tube f, a lead-holding tube h, and a propeller k engaging the slots of the tube f and the screw-threads of the tube d. The propeller k fits friction tight in the tube h so that the tube travels with the propeller except when it engages stops f and g in the tube f. The stop f<1> is constituted by a tube inserted in the end of the tube f, and the stop g by a V-shaped piece of half round wire in the tube f. The tube f is closed by a cap f<4>. The tube d is extended beyond the end of the casing a and carries the operating-head a<1> for the mechanism which may serve as a refill receptacle. The ring e of a pocket clip, preferably secured either to the head a<1> or to the tube c, is mounted between the adjacent ends' of the casing a and head a<1>. In use, the lead-holding tube h is stopped at the forward end by the stop f<1> to permit the propeller k to be pushed further forward and eject the end of lead b, and on the return movement the tube h is carried along by the propeller until it engages the stop g. The propeller passes between the legs of the stop and so is withdrawn from the tube h to permit the insertion of a lead.

Title: Improvements in and relating to furnaces
Filed: 1922-03-28
Abstract: 198,147. Seddon, W., and Chedlow, D. March 28, 1922. Smoke, consuming.-In furnace constructions of the type comprising two or more furnaces having flues and dampers so arranged that unconsumed smoke, &c., from one furnace or set of furnaces is consumed in another furnace or set of furnaces, the dampers, &c., are provided with means which locate them in correct position relative to one another while permitting them to remain for a predetermined time in any given position. The invention is shown as applied to a Lancashire boiler. The side flues b are divided horizontally by plates c, each flue thus formed being provided with a damper d, e, the dampers being secured at right-angles to each other on shafts f. At the top of the shafts f are levers h connected together by a link g, so that, when the upper side flue on one side of the boiler is open, the upper side flue on the other side is closed. The flue space at the rear of the boiler is divided by a vertical partition a, so that each side flue b is in communication with one furnace flue only. The front ends of the upper side flues communicate with chambers p, which connect one side flue with the front of a furnace flue on the other side of the boiler. The front ends of the lower side flues communicate with the bottom flue leading to the stack. In operation, with the dampers in the positions shown, smoke, &c., produced in the right-hand furnace flue, say, passes by the upper right-hand side flue c to the front of the left-hand furnace flue, where it is subjected to the heat of the fire there, and then passes by the lower left-hand side flue d and bottom flue to 'the stack. After a predetermined time, the position of the dampers is reversed by the motor-driven link n causing the sector k to rotate the pinion i on one of the shafts f. The link n is slotted and engages a pin on the sector k, thus providing lost motion. The dampers thus remain stationary for a time and then are changed over rapidly.

Filed: 1929-03-21
Abstract: 332,527. British Celanese, Ltd., and Taylor, W. I. March 21, 1929. Cellulose carboxylates. - Artificial yarns, threads, or filaments of cellulose acetate or other cellulose derivatives are subjected to a vacuum treatment subsequent to the spinning operation in order to remove the residual solvent, and the solvent thereby removed is conveyed to a solvent recovery plant. The process may be carried out with the assistance of heat, and small quantities of air or other gas, heated or not, may be passed over the yarns or the like during the vacuum treatment. The yarns may also be subjected to a humidifying atmosphere either during or after the vacuum treatment. The process may be carried out in a convenient manner in a chamber constructed of ribbed cast-iron plates and arranged with doors at each end so that the trays containing the yarn in the form of bobbins, cheeses, hanks or the like may be introduced at one end, and after treatment removed from the other end. In carrying out the invention, the yarn is introduced into the chamber and a slight vacuum, say 2 in. of water, is first applied until the yarn has acquired the temperature of the chamber, which may be from 60‹ to 70‹ C., and a high vacuum of about 28 in. is then applied until the solvent is removed.

Title: Improvements relating to the construction of field coils for dynamo-electric machines
IPC: H02K3/18
Filed: 1925-04-08
Abstract: 253,279. Kearley, N. E. April 8, 1925. Coils and conductors. - A field coil especially applicable to traction motors is made by superposing a number of stampings of sheet material connected by tongues formed on the stampings between their inner and outer edges in such a way that when the elements are alternately reversed during assembly the tongues are in position for being joined to give a continuous coil without projections beyond the main external and internal surfaces of the coil. The stampings may all be of the same form or of slightly differing forms, with a central opening shaped according to the cross-section of the core, and if a coil of conical or other non- parallel external shape is required they are made of graded width between their inner and outer edges, their thickness optionally being greater in the narrow stampings to preserve a constant cross-section of the conductor 'throughout the coil. In the rectangular stamping shown in Fig. 1, for use in a coil made up from identical elements, the tongues a, b and separating gaps c are symmetrically disposed about the centre line X, Y. Alternate stampings in the pile are reversed, face for back, during assembly and the insulation is either inserted in sheet form or applied directly to one or both faces of each stamping. Fig. 3 shows the jointing method, wherein one tongue a of the first stamping forms the coil terminal and the other b is connected to the first tongue b<1> of the second stamping which is insulated from the first at d, d'. The second tongue c of the second stamping is connected to the first tongue c' of the third stamping, and so on, the insulation f between the joints being twice as thick as the layers d, d<1> between the coils. The tongues are held in conductive contact by pressure or by an insulated bolt which traverses them. Alternatively, they may be tinned before assembly and sweated together by heat applied after the coil is made.

Centreless grinding; guides and rests.-In a centreless grinding machine for bevelling the ends of rollers for roller bearings or other articles such as tubular articles, the rollers &c. 19 are rotatably received in pockets 16 in a magazine 15 which is traversed between a grinding wheel 11 and a regulating wheel 12. The magazine slides in a longitudinal slot in the work support and the axes of the pockets are inclined to the path of travel at an angle suitable to the bevel required usually from 15‹ to 35‹. The rollers are positioned against shoulders 17 in the pockets at the side of the magazine next to the grinding wheel. The axes of the wheels 11, 12 converge slightly and the axes of the rollers are preferably inclined to the horizontal so that their points of contact with the two wheels are on opposite sides of a plane passing through the centres of the wheels. The rollers may be roughly bevelled before grinding, as shown, or may have sharp corners, the magazine then being adjusted to allow the rollers to approach the grinding wheel during operation or the grinding wheel is provided at the entrance edge with a bevel to facilitate the formation of a rough initial bevel on the rollers. After treating the bevels at one end of the rollers they may be reversed in the same machine or have their remaining ends treated in a separate, machine. The rollers make contact with the regulating wheel first and the openings 18 at the top of the pockets facilitate the washing off of waste material. In a modification, the regulating wheel 12 is replaced by a grinding wheel, both ends of the work then being bevelled simultaneously.
