Title: Automatic embroidering machine
IPC: D05C7/00
Filed: 1924-11-04
Abstract: 224,527. Singer Manufacturing Co., (Assignees of Myers, W.). Nov. 5, 1923, [Convention date]. Universal-feed machines.-The feed-direction is controlled by a continuously rotating pattern cam, and the pattern is varied by stopping the stitching and feeding during selected portions of the feed direction cycle. The stitching and feeding mechanisms are described in Specification 152,092, and are provided with a usual stopping device, which includes a cam 38 pressed to the right on the shaft 8 by a spring 41 so as to carry a pin 40 riding in a hole in an eccentric 36 fast on the shaft 8 into a hole in the gear wheel 109 fast on the pulley shaft 5. The cam causes a lever 42 to oscillate during stitching, and when that oscillation is prevented by a block 46, which can be raised into the path of the end of the lever 42, the cam is forced to the left and the stitching and feeding shaft 8 is uncoupled from the pulley shaft. The feed-direction cam disc 51 is rotated by a ratchet-pawl 82, pitman 87 and an eccentric 88 on a continuously rotating shaft 97 geared to the pulley shaft by bevel-wheels 108, 109. The cam-groove 52 is entered by a roller on a pivoted plate 55 formed with a toothed rack 58 by which the feed-direction shafts 28, 29 and 31 are controlled. The size of the pattern is changed by altering the eccentricity of the eccentric 88 and so varying the throw of the ratchet pawl. The eccentric comprises a disc 94, Fig. 4, fixed on the shaft 97 and a bush 89 slidingly mounted in a groove 93 on the disc. The parts are secured together by screws 102 and the bush can be moved in the groove to enable a positioning pin 107 to pass through one of the holes 104 in the disc into one of the holes 106 in the bush. Interchangeable ratchet wheels 74 with tooth pitches corresponding to the three throws of the eccentric may be provided. The character of the pattern can be varied by cutting out parts of the complete pattern provided for by the cam-groove. This is effected by stopping the stitching and feeding operations during selected portions of the rotation of the cam disc. To this end, screws 112, 113 are placed in two lines on the periphery of the cam disc and their heads alternately engage sloping surfaces 116, 117, Fig. 5, on a lever 121 and move that lever first to one side and then to the other. One movement of the lever causes a toe 132 to rise out of contact with a bar 133 which is then raised by a spring with the stopping block and the shaft 8 is declutched. Subsequent movement of the lever in the other direction depresses the rod 133 and the stitching and feeding mechanism are re-started. For turning corners for example, the cam control of the feeddirection can be suspended by means of a lever 67 carrying an eccentric pin. When the lever is turned, a sleeve 64 integral with the pinion which engages the rack 58 is moved on the shaft 28 against a spring, and its clutching surface 60 is separated from a similar surface on the collar 61 on the shaft 28.

Filed: 1945-10-12
Abstract: 602,122. Releasable fastenings. FAIREY AVIATION CO., Ltd., EVANS, A., and EDWARDS, W. E. Oct. 12, 1945, No. 26731. [Class 44] A turn button for an aircraft cowling or the like comprises a shank m mounted in the cowling panel a carrying an oval head v bevelled at w which is inserted through a similarly shaped hole in the fixed panel (not shown). Rotation of the head on account of its bevelled formation forces the cowling and fixed panel together. The shank has a head n, a spherical surface on which engages a spherical seating e secured to the panel a, the end of the shank being formed as a cylindrical projection o. The shank is locked in either the operative or inoperative position by means of a flat member q housed in a diametral slot in the shank and having lugs projecting beyond the shank which are urged by a spring 22 to enter one of two pairs of notches k in an upward cylindrical extension j of the seating e. The two pairs of notches are of unequal depth. The position of the button may thus be observed from the depth of the member q, this being flush with the end of the part o in the operative position. The notches k may be cam-shaped at entry. The member q is provided with a gap t engaging a pin s straddling the housing slot to prevent lateral displacement of q. The head v is adjusted by screwing on the shank and is locked in the adjusted position by a member z housed in a diametral slot in the shank and pressed upwards by the spring 22 to enter a cross-cut x in the head. If fine adjustment is desired, several cross-cuts may be provided. To actuate the button, a screw-driver or like tool is inserted in the slot at the lower end of the shank, first raising the member free of the slots k and then turning the shank. In a modification, the head v is replaced by a cotter-pin which may be mounted between a washer and an adjustable retaining nut. In another modification, the shank is hollow and the spring is mounted inside it, adjustment of the effective length of the shaft not being provided for.

Abstract: 655,225. Automatic circuit-breakers; thermal switches. PRICE & SON (STAMPERS), Ltd., T., 'and PRICE, E. E. Oct. 16, 1948, No. 26949. [Class 38((v)] A switch adapted to complete a circuit and to be opened automatically at the end of a predetermined time, comprises a bell-crank lever 14 pivoted at 15 and carrying connected contacts 24, 25. The lever is moved clockwise to close contacts 24, 28, by the momentary energization of an electromagnet 18 or by means of a cam acting on the part 16 of the lever, the contacts being held closed by an adjustablypivoted lever 33 which falls down on to a step 22 on the lever 14. Closure of contacts 24, 28 energizes the controlled circuit and also the heater 37 of a bimetal strip 35, which eventually bends up to lift the lever 33 above a step 21 on the lever 14, which is moved counter-clockwise by a spring 17 to open contacts 24, 28 and close 25, 31. The latter reclose the controlled circuit, but not that of heater 37, so that the bimetal cools down and, in bending back to its original position, engages the edge of step 22 and pushes the lever 14 back to its middle position shown, where all contacts are open, thus completing the cycle of operations. An adjustable weight 45 is placed on lever 33 so as to vary the time taken for the bimetal to lift the lever. The switch may be horizontally mounted if the lever 33 is spring-biassed.
