Title: Improvements relating to the electric control of point operating mechanism for railways and the like
IPC: B61L5/06
Filed: 1942-04-09
Abstract: 556,613. Operating railway points and signals. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., PETER, L. H., MACGREGOR, R. M. April 9, 1942, No. 4657. [Classes 104 (i) and 105] In the operation of railway points and signals by an electric motor M fed with current by a hand generator G through wires 2, 3, the motor and, optionally, the generator, are provided with one or more permanent magnets constituting the field. The normal and reverse limit switches N5, R5 are in series with rectifiers R1, R2 respectively, and with a common snubbing resistance W. The limit switch N5 opens immediately the points begin to move from normal position, and the switch RS opens directly the points begin to move from full reverse. The generator G supplies current to 2 and 3 in one direction or the other according to the setting of a control lever L adapted in one position to short circuit G through contacts N, R, and in another to connect G to 2 and 3 through contacts B or D. In another form, a two-winding relay controlling four contacts is arranged between 2 and 3 to break the motor circuit when the points are fully closed. In another form, a source of alternating current is combined as an alternative with G and supplies current through a transformer and rectifier. Specification 220,151, [Class 105], is referred to.

Title: An improved reservoir writing instrument
IPC: B43K7/02
Filed: 1945-02-26
Abstract: 589,631. Reservoir pens. ROBINSON, R. L. Feb. 26, 1945, No. 4724. [Class 146 (iii)] A reservoir pen provided with an air vent has gravity-operated means for sealing the vent when the pen is held with the point uppermost, and a passage communicating between the vent and the reservoir of such size as to permit the passage of air but to inhibit the passage of ink. The air vent 16 communicates by tubes 17 and 18 leading through the pen with a lateral outlet 19 above the reservoir 5. Rods 20, 21, and 22 slide in the tubes with sufficient clearance to allow air to pass but inhibit the passage of ink. In the carrying position, Fig. 1, the rod 20 seals the air vent 16. On movement to the writing position the rods slide so that the air vent is opened, the chamfered end 21a of the rod 21 seats on the end of tube 18 and rod 22 covers the outlet 19 to prevent ink entering. An ink trap 23 in the chamber 6 is provided which can be emptied by unscrewing the end 4. A rotatable ball 11 forms the writing point and in the carrying position it seals the top of the pen.

Title: Improvements in bobbin strippers
IPC: B65H73/00
Filed: 1928-11-16
Abstract: 326,810. Terrell, E. A. Nov. 16, 1928. Divided on 326,530. Bobbins, stripping waste from.-In bobbin stripping machines, the bobbin is deposited with its head resting on rests 7, Fig. 1, between two opposing sets of stripper blades 5, 6, and its tip within a seat 82<a>, which is acted on by a pushhead 81, causing the waste yarn upon the bobbin to be moved by the stripper blades nearer to the bobbin tip. This movement of the push-head brings the bobbin head into position to be gripped by gripper jaws 9, Fig. 5, on a pull-head 10 to complete the stripping of the bobbin. The jaws 9 are pivoted at 91 and the hubs 95 of the jaws are formed with teeth 96 engaged by teeth 94 on a rack bar 92, Fig. 8, mounted to slide in the pull-head. At the forward end of the movement of the jaws 9 towards the bobin head, the rack bar 92 is stopped by a projection 97 thereon engaging a stop 17, Fig. 7. The further movement of the pull head carries the pivots 91 forward and the teeth 94 cause the hubs 95 to turn on the pivots 91, thus closing the jaws over the bobbin head. A bell-crank lever has a vertical arm 19 within a slot in the part 97 and a lower arm having a notch which, under the action of a spring 20, engages a bar 192 extending across from one pivot 91 to the other to lock the jaws in the closed position. A stop 17 at the other end of the stroke of the pull-head engages the vertical arm 19 to release the notch from the bar 192, and the further movement of the pullhead beyond the rack bar opens the jaws 9 ready for the seizure of the next bobbin. The stops 17 are yieldingly mounted. A machine of the type to which the present invention is applicable is described in Specification 325,494, and a bobbin shoot or guideway therefor is described in Specification 325,496.

Abstract: 206,076. Evans, W. E., (Deutsche Maschinenfabrik Akt.-Ges.). Feb. 27, 1923. Apparatus with jointly-controllable drums; driving-gear.-In winding mechanism for grabs, of the type in which two drums connected by planet gearing are associated with two motors, one of which drives both drums and the other one drum only, the planet gearing is formed of spur wheels and is carried by that drum which is driven only when both drums are being driven. In the illustrated form, when the hoisting motor a is driven, the hoisting drum b is rotated through the gearing n, o while the opening drum d also is rotated by the rolling of the planet pinions c on the fixed sun wheel g, and consequential rotation of the toothed wheel q. When the opening motor e is driven, the opening drum d alone is driven, the sun wheel g in this case driving the wheel q through the planet pinions acting as idlers. In one modified arrangement, the two drums are coaxial and mounted loosely on a common shaft. In this case the toothed ring q is integral with the second drum. In a further modification of this latter construction, the drum b is divided and half is placed on either side of the opening drum. In this case the gearing is duplicated.

Abstract: 1,015,102. Sawing. OWENS-ILLINOIS Inc. Feb. 12, 1964, No. 5822/64. Heading B5L. Apparatus for controlling the movement of a bundle of partition strips 75 which are to be cut to length by a saw 77 and are moved forwardly on edge by means that frictionally engage and advance the bundle comprises a stationary guide panel 76 positioned transversely of the path of the strips to halt their forward progress, an arrester bar 51 positioned generally parallel to and spaced from the panel and having a downwardly and forwardly inclined surface 52 positioned to contact the top edges of the strips, the surface terminating in a forwardly inclined knife-like edge 53, and means 46 resiliently supporting the bar in position, whereby the forward ends of the forwardly moving strips strike the inclined surface to raise the bar against the resilient supporting means and move past the bar, and strips tending to move backwardly after striking the panel will be restrained by the engagement of the knife-like edge with the strips. The apparatus is described as for use in the partition sawing apparatus disclosed in U.S. Specification 2,855,009 which has a bandsaw 77 for cutting the bundles of partitions 75 after the forward ends of the partitions have been moved into engagement with the guide panel 76 by a clamping device 71 having means for frictionally engaging the upper edges of the partitions and being movable along guide rails 72 by a rod 73 connected to an air cylinder 74. After positioning the bundle, the clamping means is released and the bundle is moved transversely past the saw 77 and the cut strips pass between the guide panel 76 and a guide rail 78. A plate 12 is secured to the panel 76 and carries a pair of upright posts 20, 21 which are connected together at their upper ends by a cross member 27 having a bore 29 for rotatably receiving the reduced portion 31 of a screw 30. A hand wheel 36 is secured to the upper end of the screw which engages a threaded bore 37a in a carriage 37 guided for vertical movement on the posts 20, 21. The carriage carries pivots 44 for a pair of cranked arms 60 secured at their ends to the arrester bar 51, the arms extending through cut-outs in the guide panel. The lower end of the bar is shaped with the inclined surface 52 and knife-like edge 53. Resilient means in the form of springs 46, air springs or the like act between plates 41 on the carriage and the arms. An extension 55 on the bar is adapted to actuate a limit switch L1 which functions as disclosed in the above-mentioned U.S. Specification. In operation, the handwheel 36 is rotated to vertically adjust the carriage so that the inclined surface lies in the path of the strips. When the strips are advanced by the clamping means 71, the arrester bar is raised to actuate the limit switch against the action of the springs 46 which cause the edge 53 to bite into the edges of the strips and prevent the strips bouncing back from the guide panel.
