Filed: 1937-12-11
Abstract: 503,983. Weft - replenishing looms. WRAY, J. W. Dec. 11, 1937, No. 34337. [Class 142 (iii)] Weft-replenishing mechanism ; weft, cutting ; weft-feeler arrangements. -In a loom employing two or more shuttles for weft-mixing and having two or more rising and falling shuttle boxes a, b at the detector side and two or more boxes c, d at the replenishing side of the loom, means i for holding the weft end of the reserve shuttle and means for cutting and removing the weft ends are provided. In a loom as shown with two boxes at each side, the box d is normally in line with the race-way ; the boxes a, b are moved at alternate picks. The weft feeler comprises a pivoted block g, a tail piece g<@> and a feeler end g<3> adjustable by means of a spring g<5> and screw g<6>. This end g<3> feels the shuttle in the upper box a when the latter is raised, but is held out of action by a connection z when the box is lowered. On weft shortage the tail g<6> holds a catch h in the path of a bunter #<6> which, through links &c. f<5>, f<4>, f<3>, f<2>, f<1> pushes the bottom end of a link e<1> off a support e<4> and allows the wheel e<5> to drop into mesh with a wheel e<6>, which makes a complete revolution to lower and raise the boxes c, d. At this time the box a contains the empty shuttle, and the box d the half empty shuttle. A full shuttle is now picked from the box c into the box b, the boxes a, b lowered and the empty shuttle picked to the box c, then the boxes c, d are raised. The empty bobbin in the shuttle in box c is replaced by hand and is ready for the next indication of weft failure. When the boxes c, d are lowered a connection y puts the weft feeler out of action. The weft end of the new bobbin is held in card clothing i<1> on a roller i which is rocked to free the end when the boxes c, d fall. The wefts extending from the selvedge to the spent shuttle and to the holder i are raised by a band k to come between the fixed and movable cutters j<1>, j<2>, and the cut ends are carried by a member m on an oscillating belt n on to a card-covered stripping roller o, driven by belts w and mutilated gearing r from the low shaft p. At replenishment a catch t is lifted and the wheel r pulled round by a spring u until it gears with the wheel p<1>; after a complete rotation, the wheel r is stopped again by the catch t. Specification 125,841, [Class 142 (iii)], is referred to.

Title: Improvements in or relating to electric motor control systems
IPC: B66C13/50
Filed: 1953-12-14
Abstract: 782,109. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd. Dec. 14, 1953 [Dec. 26, 1952], No. 34743/53. Class 38 (3). In the first hoisting position of a master switch 14, a circuit is completed to a motor armature 10 and series field winding I through relay coil 15a and over-hoist limit switch contact 16a, the circuit being completed through brake release winding 45 and accelerating resistors 47, 48, 49. To provide for stable low speed operation when hoisting light loads, contacts 23b are closed in the first hoisting position so that resistor 34 is connected in shunt with armature 10 and resistor 37. Actuation of the over-hoist limit switch opens contacts 16a, 16b and closes contacts 16c, 16d to form a dynamic braking circuit through resistor 63. The opening of contacts 16a de-energizes relay 15a, the contacts 15b opening to de-energize relay coil 23a. Thus, the contacts 23b open and the motor is prevented from driving the hook downwardly when the over-hoist switch is actuated, the brake being de-energized to hold the hook in the over-hoisted position until the master switch is moved to a lowering position. This arrangement permits the use of resistor 34 as an armature shunt in the first hoisting position, and, at the same time prevents the oscillation of the hook in the over-hoist limit zone which would be obtained if the circuit through the contacts 23b is not broken. The coil 15a may be placed in other suitable parts of the motor circuit, and it may be replaced by a coil of the voltage-operated type. This relay is not included in circuit for lowering operation, during which the motor is connected as a shunt machine with the field excitation controlled by means of resistors 47, 48, 49.

Filed: 1963-09-05
Abstract: 1,090,953. Knitting-machines. BENTLEY ENGINEERING CO. Ltd. Aug. 17. 1964 [Sept. 5, 1963], No. 35143/63. Heading D1C. A circular machine has needle selecting mechanism comprising selector jacks 4 and intermediate jacks 3a which are actuated to raise the selected needles to a height whereby they take a splicing yarn from a guide 13 in addition to the ground yarn from a guide 10. Subsequently the needles are lowered by stitch cam 14 and the intermediate jacks 3a are lowered by cam 15. A cam 16 is positioned beneath the butts of the jacks 3a which is adapted to be engaged by these butts when in their lowered position and is thereby caused to be moved downwardly. The cam 16 is coupled through linkwork with the stitch cam 14 such that its downward movement causes the stitch cam 14 to be simultaneously lowered. Therefore, the jacks 3a having raised the splicing needles cause these same needles to draw longer loops by the lowering of the stitch cam. The stitch cam and cam 16 are normally biassed in an upward direction so that after the splicing needles have knitted their stitches the cams resume their normal position. To avoid the marginal needles of the urispliced area being lowered to draw long loops, the cam 16 may be pivoted such that the initial jack butts tilt the cam 16 without lowering it as shown in Fig. 7. Lowering is effected when the cam is engaged throughout by the butts as is shown in Fig. 8 whilst the cam resumes it normal position by the end jacks tilting the cam in its reverse direction, Fig. 9, prior to the completion of knitting by the splicing needles.

Abstract: 783,043. Rolling; shearing. VICTAULIC CO. OF AMERICA. Dec. 8, 1955, No. 35275/55. Class 83 (4). [Also in Group XXVIII] Annular pipe coupling grooves 4, Fig. 2, of rectangular section are accurately formed on the outer surface of a pipe 1 by a roll 7 with an annular rib 8 while the flow of metal from the groove is controlled as by a supporting roll 11 which engages the pipe on each side of the groove. Alternatively the groove may be progressively formed by a series of rolls 35, Fig. 4, 42, Fig. 5, radially disposed about the tube and having progressively wider annular ribs 38, 43. Cylindrical portions 39, 44 serve to work back any metal flowing outwardly from the groove. In another example the groove is formed by a roll 54, Fig. 7, having cut-away grooves 56 on each side of the rib 55 which permit radial outward flow of metal near the edges of the groove. A backing roll 58 with a concave section 60 controls the outward flow to form thickened portions 62 on each side of the groove. The inside of the tube may be supported by a mandrel 52 but this may be omitted in larger diameter tubes where a reduction of internal diameter is permissible. A tool for carrying the rollers comprises a housing 26, Fig. 14, with a slidable holder 28 actuated by a screw 29.
