Title: Web feeding and label severing mechanism
IPC: B65C9/18
Filed: 1948-05-28
Abstract: 645,730. Shearing-machines. TRIGGS, W. W. (National Bread Wrapping Machine Co.). May 28, 1948, No. 14506. [Class 31 (i)] [Also in Group XV] In a labelling-machine such as described in Specification 645,729, [Group XV], the label web, having regularly spaced marginal indentations, is fed and severed by a knife-carrying roll which has its central portion cut away ahead of the knife, leaving marginal feeding portions of less width than the indentations in the web and a backing roll holding the web against the knife-carrying roll, so that the web is fed until the feeding action of the marginal portions of the knife-carrying roll is caused to cease by their passage into the marginal indentations of the web, so that the knife will sever the web in predetermined relation to the marginal indentations. A feeler 30, Fig. 5, adjustable in height for various sizes of packages, is attached to the machine by links 28, 32, 34 so that on being raised by a package passing underneath, a pawl 36 is released to clutch together a continuously rotating shaft 40, driven from the package conveyer 26, and a gear 45. The label web 113, Fig. 8, is fed under a tensioning roll 19 and between fixed rolls 48, 50 to a severing and feeding roll 70 driven by gear 45. The roll 70 is provided with a cutting blade 68 to sever the web and also with marginal feeding surfaces of less width than the indentations in the web, and a solid portion extending across its width. The marginal surfaces of the roll 70 in co-operation with a backing roll 75 feed the web until they engage the indentations of the web when the feeding stops, the roll continues to rotate until the knife 68 severs the web, and the label is drawn into the heating position as described in the above referred to Specification. At this stage, a pivoted web guiding device 78 moves under the action of a cam to free the severed end of the web from a fixed blade 67, and feeding rolls 48, 50 are moved together by a further cam to feed the web between the rolls 70, 75. The solid portion of the roll 70 then engages the web until the marginal indentations have been passed. Rolls 40, 50 move apart again and the operation is repeated. Roll 48 is rotated by gear 45 and is provided with a printing surface 63 which prints the desired indicia on each label as it passes.

Abstract: 751,286. Friction clutches. DANA CORPORATION. May 19, 1954 [July 20, 1953], No. 14656/54. Class 80(2) The two spring-engaged clutches A, B of a double friction clutch are controlled by a single pedal or lever operating a slidable sleeve 33 which acts, through a single set of radial levers 37 pivoted on a back plate 40 secured to the driving flywheel 10 on a single set of disengaging rods 30. The driven disc 14 of clutch A, splined to a first output shaft 25, is normally engaged between the flywheel 10 and a presser plate 12 rotating therewith by a spring disc 15 acting between plate 12 and an abutment plate 20 fixed to flywheel 10. The driven disc 47 of clutch B, splined to a second output shaft 31, is normally engaged between plate 20 and a presser plate 45 rotating therewith by a spring disc 59 acting between plates 40, 45. In Fig. 1, rods 30 act directly on plate 12, while adjustable studs 64 are interposed between plates 12, 45, so that clutch A disengages first, followed by clutch B. In Fig. 3, the rods act directly on plate 45 through adjustable nuts 64' and act on plate 12 with lost-motion at 24', so that clutch B disengages first, followed by clutch A. The nuts 64<SP>1</SP> may, however, be so adjusted that the clutches disengage in the reverse order or simultaneously.

Abstract: 217,418. British Thomson-Houston Co., Ltd., (General Electric Co.). June 7, 1923. Electro magnetic switches; retarding devices.-A meter of the indicating type, which may be used as a relay to perform operations at the end of equal units of metered current or energy, is provided with a damping-device of the integrating-meter type, so that an integrating indication is obtained. A test meter for calibrating an ampere hour meter A, Fig. 1. consists of a permanent magnetic field 6 surrounding the coil of the moving element 7. The moving coil is connected across a shunt 2 in the main circuit, the connection being made by light spiral springs 12, 13 exerting no appreciable torque on the moving member. Mounted on the shaft 8 is a copper . or other conducting disc 14 rotating between the poles of a. braking magnet 15. The upper end of the shaft 8 is provided with a pointer 16, Fig. 2, moving over a scale 17. An arm 18 is provided for setting the pointer 16 to zero by hand, the arm in the position shown in dotted lines serving as a stop for the upper extremity of the scale. As the damping effect increases with the speed of rotation of the moving element, the time taken by the pointer to attain a certain deflection is inversely proportional to the average current. To calibrate the meter A, the circuit of the test meter is closed by a switch 5 whilst the meter A makes a certain number of revolutions. On opening the switch 5, thepointer 16 remains at the point on the scale to which it has moved. A watt-hour meter W may similarly be calibrated if the pressure of the circuit is constant; in other cases a potential coil magnet is provided in place of the permanent magnet 6.
