Title: Stop-motion mechanism for sewing machines
IPC: D05B69/22
Filed: 1954-10-06
Abstract: 751,938. Sewing - machines. SINGER MANUFACTURING CO. Oct. 6, 1954 [Oct. 9, 1953], No. 28773/54. Class 112. [Also in Group XXIV] Starting and stopping gear.-In a sewing- machine a stop-motion mechanism for a rotary shaft 20 comprises a stop member embracing said shaft and having an arm 46 extending radially with respect to the latter, a cam element 57 which is fixed to the shaft and is formed with a stop shoulder spaced radially from the axis of the shaft, a stop-rod 49 pivoted at 48 to the stop arm radially outward of the stop shoulder, spring means 54, 55 associated with the stop-rod for resisting longitudinal movement thereof, an means for moving the stop-member into and out of the path of rotation of the stop shoulder. As shown, the invention is embodied in a tacking- machine, the feed of which is controlled by a rotary pattern cam 18, for the purpose of bring- ing the machine to rest in a definite position at the completion of each tack. The stop member comprises a sleeve 45 rotatably carried in the end of a lever 43 pivoted at 42 to the machine frame 3. A spring 59, interposed between the frame and lever 43, biases arm 46 into engagement with the cam element 57. The latter is in the form of a face cam integral with a pulley element 23 fast with shaft 20, the cam being so formed as to lead the arm into a recess 58, when the arm engages a side wall of the recess constituting the stop shoulder. A loose pulley element 26, journalled on shaft 20, may be moved against the bias of a spring 33 for moving a V-belt 31, which normally runs on element 26, into engagement with the fast element 23 for transmitting drive to shaft 20. One arm 63 of a bell-crank lever, pivoted at 61 to the frame, is connected by a chain 64 to a treadle which, when depressed, urges the cam-shaped end 65 of the other arm against the lever 43, thereby moving the latter against spring 59 to disengage arm 46 from recess 58. An arm 38 carried by lever 43 simultaneously engages loose pulley element 26 to carry the belt into engagement with fast pulley element 23. Lever 43 also depresses the nose of a latch 68, pivoted at 69 to the machine frame, against the bias of a spring 72, and is thereby retained by the inner notch 75 of a pair of notches 74, 75 formed in said nose, the tail 78 of the latch being biased against the pattern cam 18. Three stitches before the end of the tack, tail 78 is engaged by a projection 80 on cam 18 to rock the latch sufficiently to allow lever 43 to move from notch 75 to notch 74, whereby arm 38 is freed from the loose pulley element and the drive is disconnected. One stitch before the end of the tack, nose 78 is engaged by a projection 79 on cam 18, whereby lever 43 is freed from notch 74 and arm 46 is thereby carried into notch 58 to stop the machine, the momentum of the moving parts being absorbed by springs 54, 55.

Filed: 1948-11-10
Abstract: 651,951. Electrotherapeutic apparatus. NEMEC, H. Nov. 10, 1948, No. 29181. [Class 81(ii)] Electromedical apparatus comprises two separate sources of variable current energizing separate pairs of electrodes and having inter-related control means so that interaction of the fields produced gives a desired stimulation in the depth of the tissue without influencing the surface areas. In the embodiment described a power transformer 1 supplies two separate rectifying and smoothing circuits, each giving a direct current across a potentiometer, from which an output for electrodes 11, 12 and 13, 14 is taken through a control circuit consisting of resistors 2, 3, condensers 5, 6 and coupled, mechanically driven contacts 7, 8, 9. Contact 7 is closed to charge condenser 5 and then opened, so giving a gradual increase of current between electrodes 11, 12, followed by an exponential decrease. as in curve 1, Fig. 2. Contacts 8, 9 are closed during charging of condenser 6 and, at a time before the opening of contacts 7, both are opened and contact 9 moves from position 10 to 10<1>. In this case the increase in current through electrodes 13, 14 is followed by a sudden decrease, as in curve 2, Fig. 2. The electrodes are so placed that their fields 15, 16, Fig. 1, overlap in opposition in the area 17 and although the rates of increase and decrease of the individual fields are not sufficient to produce any stimulation, the resultant field, (see curve 3, Fig. 2,) varies in such a way as to produce the desired effect in the internal area 17
