Abstract: 317,705. Marks, E. C. R., (Elliott-Fisher Co.). May 29, 1928. Divided on 317,915. Sheet and web clamping, guiding, and cutting arrangements; paper-supports.-A flat platen for a typewriter or like machine is associated with paper-clamps arranged for successive operation, and preferably so that release of the work from some of the clamps is effected by moving those clamps, and release from others is effected by moving the platen. One of the movable clamps may engage a cross-bar of the framework and be provided with a cutting-edge. When a transversely folded web is employed it is smoothed before passing on to the platen by means of a device comprising a rocking set of spaced plates between which pass the plies of the web. The platen 14 shown in Fig. 3 rests at the rear on rollers 33 carried by spring-urged bell-cranks 31, the rear end of the platen normally abutting on clamps 17 carried by slides 18 which are adjustable on a cross-bar 11 of the framework. The platen is provided at the front with pins 13 passing through lugs 12 on the front bar 9 of the framework, springs 15 normally holding the platen in contact with washers 16. Clamps 20 projecting over the sides of the platen are secured to arms 21 which are loosely mounted on a shaft 22 and are connected to springs 23. A clamp 25 formed with a cutting-edge 26 engages the bar 9 and is secured to arms 27 on the shaft 22, depending arms 29 on the shaft being connected by springs 30 to the bell-cranks 31. The clamps are employed to hold sheets and a multi-ply web, the clamps 17 serving also as side and rear gauges for the web and sheets. The arms 27 carry pivoted abutments 41 for engaging pins 40 on the arms 21. Rocking arms 35 engage forked arms 28 on the shaft 22 and have pins 43 engaging slotted links 42 suspended from the platen. The arms 35 have a cross-bar 36 supporting a bail 36 which abuts on the shaft 22 and is connected to a pedal by means of a chain 38. On depression of the pedal, the arms 27 raise the clamp 25, the abutments 31 cause the arms 21 to raise the clamps 20, and the platen is depressed at the rear, the web being released successively from the clamps 25, 20 and 17. Thereupon the web can be drawn forwards until another length is positioned on the planten. The pedal is then released to restore the clamps and platen and the typed length is severed by means of the edge 26. When two webs are arranged side-by-side and it is required to draw forward one web only, the abutment 41 associated with the other web is lifted to prevent operation of the corresponding clamp 20. For smoothing a transversely folded multi-ply web a, Fig. 6, before it passes on to the platen, the plies are passed between plates 70 mounted on supports 71 which are pivoted at 72 on the framework, stops 73 permitting limited rocking of the supports. Platen indicators.-The cutting line of the web is indicated by means of fingers 44 which project over the sides of the web and are formed on spring-urged bell-cranks 45 adjustable by means of screws 46.

Class 131 [Also in Group XXXV] In a dry shaver shown comprising a boxlike casing made in two sections and screwed together. a cutting head carried by the casing and including a stationary outer shear plate and reciprocable inner cutter, and an electric motor for driving the cutter housed in the casing, the motor includes a stator 13 fitting freely within the casing and having a projection 13a constituting a knife-edge and an armature 15 pivotally mounted on the knife-edge 13a  connected to the reciprocable cutter 23 by means of a spring 35. The armature includes a laminated part 15a adapted to enter more or less deeply into a gap in the stator as the armature rocks on its pivot. The armature is held on the pivot by two compression springs 17 and 18 on opposite sides of the pivot, between a wall of the casing and the armature. They also serve to press the stator against the opposite wall of the casing and to help the rocking movement. The springs tend to hold the armature in a position in which the laminated part 15a is not fully entered into the gap in the stator. The stator is also held by resilient pads in the top and bottom of the casing and a spring 26 urges it against the opposite wall. The spring is separated from the stator by an insulating strip 28. The spring also helps to hold the cap 25 carrying the shear plate 24 and a button 27 releases the spring from the projection 25b of the cap. The cap is also held by the projection 25a. The action of the armature is transmitted to the cutter 23 by means of an actuator 16 of roughly T-shape, its flanges 16 a being held against the armature by means of the springs 17 and 18 and having a vertical rod -16b at the end of the shank projecting out of the casing. The actuator is connected to the cutters by means of a spring 35. The cutter is mounted in guides which allow limited movement of the cutter transversely of its direction of reciprocation, and the spring 35 also urges the cutter on to the shear-plate. The electricity is led into the coil 14 by means of terminals 21 and a cable passes through the casing. A switch may also be installed to select coils for different voltages. Specification 788,305 is referred to.

Abstract: 330,637. Peter, L. H., Pearce, W. A., and Westinghouse Brake & Saxby Signal Co., Ltd. March 15, 1929. Hand-levers, interlocking.-In an electrical interlocking apparatus for railway point and signal levers an auxiliary electrically released lock is provided so that a lever is arrested, after only a short movement from its extreme position, by this auxiliary lock which is energized only when the lever has effected its short movement and if the other levers are in their appropriate extreme positions. Alternatively the short movement may be provided by a catch handle, with the lever locked in its extreme position and then released as above. Figs. 1 and 2 show the arrangements for a cross-over from a main line to a siding, the points 1 and lamp signals 2, 3 being controlled by levers L1, L2, L3. The various lever-actuated contacts' shown in Fig. 2 are lettered correspondingly with Fig. 3 to indicate any position of the lever in which they are closed. To permit the movement of a train from the siding S the points 1 are set by moving the lever L1 from position N to R, Fig 3, subject to the interlocking control with the main line signals (not shown). The signal lever L2 may now be moved over, as on reaching position A its contact 11 is closed and, as levers L1 and L3 are in the appropriate extreme positions, the contacts 12 and 13 thereof are also closed so that the coil K2 is energized to release the lock P2 and permit the passage of the lever L2 beyond the A position. The circuit of green " proceed " lamp g of signal 2 is closed when the lever L2 is moved over, the contacts 22 and 18 controlled by the other levers being closed. Similar conditions control the actuation of signal lever L3 when it is desired to pass a train into the siding. To return the points lever L1 it is necessary that both signal levers be in position N, with the lamp signals showing the red " stop " lamp r, to close their contacts 20, 21 so that the coil K1 of lock PI may be energized when the lever L1 reaches position E and closes contact 19. The auxiliary locks are arranged not to contact with the bottom of the locking recesses in the bar. B, D are the positions in which further movement of the levers is prevented by the usual check locking mechanism (not shown).
