Title: Improvements in or relating to mechanisms for producing rotational movement of a mass about an axis with a periodic reversal of the direction of rotation
IPC: F16H33/02
Filed: 1956-09-27
Abstract: 818,821. Reverse gearing; friction clutches. GENERAL ELECTRIC CO. Ltd., and BRIDEN, H. Sept. 26, 1957 [Sept. 27, 1956], No. 29605/56. Class 80 (2). A mass is oscillated back-and-forth in an arc of a circle with the movement of an arm driven through reverse gearing by a continuouslyrotating motor, the gearing containing a double clutch which is first engaged to swing the arm in one direction and is automatically disengaged when the end of the arcuate path is neared, a spring then being put under strain to absorb the kinetic energy of the mass and reverse its direction of travel, automatic re-engagement of the clutch swinging the arm back in the opposite direction. At the other end of the arcuate path, the process is repeated, and continues as long as the motor operates. In the form shown, the mass is a radar reflector mounted at the end of an arm 2. An electric motor drives through gears 7 to rotate two gears 5, 6 continuously in opposite directions. A gear 10, fast on an axially slidable shaft 11, lies between the gears 5, 6 and carries on its opposite faces friction linings 14 engageable with the continuouslydriven gears. The gear 10 meshes a toothed segment 24 fast with the arm 2. The shaft 11 carries a piston 20 in a cylinder 21, to which. oil under pressure is supplied through a control valve 23 to raise or lower the piston and hence engage the friction linings on the gear 10 either with the gear 6 or with the gear 5. A torsionbar spring 27 has its upper end fast with the arm 2, and its lower end secured by a tubular case 28 to an arm 29 which engages at the ends of the oscillating movement of the arm 2 &c. with stops 32, 33 fast on a frame member. Pins 30, 31 pass through the two stops 32, 33 and engage at their inner ends with a lever 34 which rocks between two end positions and is connected by links 36 to the control valve 23. As the arm 2 swings in one direction or the other, the arm 29 traverses with it and approaches one or other of the stops 32, 33. When the radar reflector approaches the end of its travel, the arm 29 first engages one or other of the pins 30, 31, and rocks the lever 34 so that the links 36 move the control valve 23. The piston 20 and shaft 11 are thereby allowed to move to a, posi. tion where the gear 10 is free of both the gears 5, 6. The arm 29 then engages either the stop 32 or the stop 33, and the spring 27 is accordingly twisted. The kinetic energy of the radar reflector and its arm 2 are absorbed by the spring 27, which starts the arm 2 &c. moving back in the opposite direction. During this process, the piston 20 and shaft 11 continue to move, and engage the friction linings 14 on the gear 10 with whichever of the gears 5, 6 was previously not engaged. Drive then takes up and the arm 2 is swung by the motor in the opposite direction.

Abstract: 297,492. Langdon, F. E., and International Neopost, Ltd. June 22, 1927. Franking - machines. -In a postal franking- machine comprising a printing-roller 1, Fig. 1, over which the letter &c. is fed and an impression roller 19 arranged above the roller 1, a franking- die 4, Fig. 2, is provided having a slot 5 through which projects one face of a multi-die 6, which is adjustable to alter the value of the impression printed. The die 6, which, as shown, has two faces 7, 8, is pivoted at 15 and has a projection 14 engaging a groove 13 in a shifting- block 10 fixed on a shaft 2a, which is arranged inside a hollow shaft 2, carrying the roller 1, and is moved in and out by means of an external knob 18. The movement of the shifting-block also moves one or the other of two gears 16 into operation to actuate counting-mechanism in proportion to the value of the die-face in use. In general construction, the machine described is similar to that described in Specification 251,338, the printing &c. mechanism being arranged in a two-part casing 9, 20. The roller 1 is rotated by turning a handcrank 21, Fig. 3, normally locked against movement by a, releasable stop consisting of a pin 22 fixed to the handle, 21 and withdrawn by pulling out the handle against the action of a, spring 24. The roller 1 carries dating, cancellation, &c. dies in addition to the value die, the base of the casing 9 being formed with a well 31 in which is a grid 32 through which a tool may be inserted to adjust the date-wheels. A feed-table 25 is provided with gauge lines 26, 27, 29, Fig. 4, to facilitate positioning letters on which value impressions are to be printed side by side. A letter is moved up to the line 26, and the machine is operated to print from all the dies ; the letter is then positioned successively up to the lines 27, 29, and the handle 21 is rotated sufficiently to print value impressions only, the impression roller 19 being released by hand as soon as necessary each time. To avoid smudging the value indication of a previouslyprinted impression, the cancelling-die may have a slot or a blank space where it would cover the value indication if the printing-roller were rotated too far. The feed-table 25 may have an extension 33, Fig. 3, which overhangs the knob 18 and is attached to the casing 9 by keyhole slots engaging over screws 35. Specification 287,301 also is referred to.

Abstract: 655,785. Roller conveyers. FISHER & LUDLOW, Ltd. Nov. 19, 1948, No. 30066. [Class 78 (i)] Figs. 1 and 2.-Retarding rollers 15 are interspersed among conveying rollers 12 of the roller conveyer. Each retarding roller 15 is freely mounted in bearings on a spindle 19 which is preferably secured by pins 32 to arms 21 secured to shaft 22, pivoting in the conveyer framework 14. Spindle 19 carries rigidly a pair of vanes 26 which curve outwards towards the roller and the roller is partly filled with heavy oil so that as a load passes over the retarding roller, the latter rotates and the friction of the oil between the vanes and the roller checks the rotation of the roller and therefore the speed of descent of the load, the retarding force increasing with the speed, the pivotal upward movement of the arms about 22 increasing the retarding effect. Figs. 1 and 4.-Spindle 19 is preferably carried by slots 20 slotted into the sides of framework 14 and is urged upwardly in said slots by springs 25, each connected between spindle 13 of a normal roller 12 and pin 32 on arm 21 so that each retarding roller 15 is slightly raised above the normal convey surface to ensure that the said roller does contact the descending load.

Abstract: 847,191. Friction clutches. BENDIX AVIATION CORPORATION. Sept. 19, 1958 [Oct. 2, 1957], No. 30080/58. Class 80 (2). [Also in Group XXXIV] A brake or clutch comprises one or a plurality of friction segments, each mounted in an opening in a carrier plate by yieldable means permitting limited circumferential movement of the segment relative to the plate. A carrier plate 12, splined for axial movement, has circumferentially-spaced openings 20 each containing a friction segment 10 of a friction material 36 in a cup 38, 40 formed with a central opening containing a button 30 clamped by a flange 42 between the cup base 38 and the material 36. Two such segments 10 are fastened together back-to-back, Figs. 3 and 4, by a rivet 46, the buttons 30 being situated in a central opening 28 of a mounting-member 26, Fig. 5, having openings 32 forming resilient deformable edges 34 which engage the rounded ends 22 of the openings 20. On clutch engagement, friction tends to move the segments circumferentially, such movement being transmitted to the plate 12 via mounting-members 26, and the edges 34 deforming to dampen any vibrations set up. The straight ends 24 of the openings 20 limit the circumferential movement of the segments 10 which are also prevented from rotating by a projection 48 on each cup base 38 engaging an oblong opening 50 in plate 12. The mounting-members 26 may be each formed with edges 34 of different spring rates to reduce the possibility of encountering a vibration common to each pad resulting in chatter. In Fig. 6, not shown, the member 26 is curved to hold each cup 38, 40 from the plate 12 to permit limited axial movement of the pads.
