Title: Systems for operating electric reciprocating motors or the like
IPC: H02K33/12
Filed: 1923-01-23
Abstract: 194,266. Central Electric Tool Co., (Assignees of Weyandt, C. S.). March 6, 1922, [Convention date]. Percussive tools.-The core of a reciprocating motor having two solenoids for use on an alternating-current system is reciprocated, for instance for operating a tool as shown in Fig. 2, by supplying alternate half-waves of the current to each of the solenoids through thermionic or other one-way valves reversely bridged across the supply mains. The use of two thermionic diodes 6, 8, for this purpose on an alternating supply 1, 2 is shown in Fig. 1. The filaments 5, 7, which are heated by transformers 3, 4, are respectively connected at 9, 9<1> to the mains 2, 1, and the anodes 10 11 are respectively connected to the mains 1, 2 when a coil 17 is energized to close contacts 18, 14 and 19, 15. The diodes thus allow half-waves of current in one direction to pass through the operating solenoid 27 and in the other direction through a second solenoid 28 and so pull the core 29 in opposite directions alternately. The switch 20 is opened by a spring 21 or equivalent means and is closed when a finger switch 26 connects the coil 17 across the mains 1, 2. The solenoids 27, 28, Fig. 2, are placed within radially-disposed bundles of E-shaped laminµ 35 around a non-magnetic tube 31 in which the magnetic core 29 moves between the tool 33 and a buffer 32. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also claims for supplying the solenoid of a reciprocating motor with alternate alternations of current for moving the contained magnetic element in one direction and for actuating the element for motion in the other direction by means other than the solenoid. These claims are not limited to the use of thermionic rectifiers. This subject-matter does not appear in the Specification as accepted.

Abstract: 764,455. Sausage skins, shortening by pleating. TEE-PAK, Inc. Jan. 25, 1955 [Feb. 12, 1954], No. 2227/55. Class 28(2) In shortening long lengths of cellulose sausage skins into short concertina form as in U.S.A. Specification 2,583,654 convenient for hand pushing on to the filling tube of a sausage filling machine the concertina' folds are made to interfit and yet to allow of unfolding as filling proceeds. The sausage skin from a reel is pulled by a pair of rubber conveyer belts 433 over a hollow mandrel 125 which supplies inflating air through its bore 126. The belts have spaced integral projections or dogs 432 to form the depressions for the folds in the inflated casing 52. The dogs have transverse semi-circular cut-aways to grip the casing against the mandrel. The casing is thereby fed forward and compressed into the folds 467, Fig. 5 against a yielding collar (192, Fig. 2, not shown). The folds comprise longer major folds 468, Fig. 5 extending around the top half of the circumference and slightly offset from similar major folds in the lower half circumference and in the bottom of these folds are shorter minor folds 469. The folds 468 are made by the initial offset between the staggered top and bottom dogs 432, the lower dogs being in advance of the top set. Fig. 6 shows an arangement of four travelling belts 475 surrounding the casing, each belt having dogs 476 with semi-circular openings 477 and projecting inwards to initiate the folds in the casing, the dogs of each belt being offset longitudinally with respect to the next belt, so that a series of semi-circular folds may be produced, each such fold being offset with respect to the next semi-circular fold. Fig. 7 shows the inflated casing being pressed into preliminary depressions or folds by surrounding dogs 483 on each of three travelling belts 482 at 120 degress the dogs being mutually staggered so that one part of a casing section always remains undepressed or folded, the depressions being completed into folds by end compresion against the yielding plates as above. As a variation, the belts may be traversed at different speeds and one or more belts may be smooth i.e. without dogs, the belts may be arranged to encase any polygonal section e.g. square or hexagonal.

Abstract: 228,545. Deloison, F. P. M., and Deyon, J. D. B. Feb. 1, 1924, [Convention date]. Addition to 222,089, [Class 103 (i), Brakes &c.]. Systems controlling travel for a fixed distance; electric braking; controllers, drum.-In the means for braking wagons in railwaysidings described in the parent Specification, comprising a brake shoe which is placed in position on the track by means of a carriage connected to an endless cable wound on a motor-driven winch, the range controller is arranged to control the positioning of the shoe. The motor controller comprises a handle 1, Fig. 1, adapted to rotate a shaft 4 carrying, a drum 5, and a pulley 6 braked by a member 14 and grooved to receive a cable 7 carrying a weigth 9 guided in a tube 10. The drum 5 is made of insulating material and is partially surrounded by a copper strip, so that when the handle is in its inoperative position, one of two contacts 12 bears on the strip and the other on the drum. When a wagon approaches, the handle is rotated to the desired extent, thereby raising the weight 9 and causing both contacts 12 to bear on the copper strip. On depression of a stud 13, the circuit of the motor 59, Fig. 4, is closed through an automatic contact 16, whereby as in the parent Specification, the winch is driven to cause the shoe to be moved on to the track. The handle 1 is released as soon as the motor circuit is closed and is returned to inoperative position by the weight 9, the tima taken to break the motor circuit by the movement of one contact 12 off the copper strip determining the position of the shoe. As in the parent Specification, the initial movement of the carriage closes a switch 64 on the circuit of the motor 76 and an automatic contact 17, so that as soon as the circuit of the motor 59 is broken, that of the motor 76 is closed by the contact 17, to return the carriage to its initial position, this latter circuit being broken when the carriage again meets the switch 64. The armature of the contacts 16, 17 then takes up a nuetral position, in which it closes a circuit through the motor armature 58 and the motor 59, whereby the latter acts as a dynamo to bring the armature 58 radily to rest.
