Granted: 1912-06-13
Abstract: 14,036. Aktiebolaget Princeps. June 15, 1910, [Convention date]. Tripping-arrangements.-Relates to the automatically-fed platen printing-press described in Specifications 193/03 and 985/03, and consists in the provision of means co-operating with the suction separator whereby the press is tripped automatically on the failure of the feed. The platen 1 is carried by a shaft 5 eccentrically mounted in rocking arms 4 oscillated by the usual side-arms 3. On the shaft 5 is an arm 6, which a spring 7 tends to turn downward to move the platen away from the type-bed 2. The arm 6 is normally held raised by an arm 9 of a bell-crank 9, 10, engaging beneath a projection 8 on the side of the arm. The downward motion of the arm 6 is limited by the engagement of a ring 13 on a rod 11, with a stop 12. Adapted to co-operate with the arm 10 of the bell-crank is a catch 15 held raised against a stop by a spring 16, and having thereon a projection 17 adapted to be engaged by a latch 18, loose on the shaft 19. This shaft carries an arm 20 connected to a piston 21 working in a cylinder 22 communicating with the separator vacuum, and a three-armed lever 24, one of which is connected to a weak spring 23. Another arm is connected by a spring 23<Î> to the latch 18 thus holding it against a stop on the third arm 17<Î>. As the platen moves in the direction of the arrow, the arm 10 contacts with and depresses the catch 15.

Title: Improvements in and relating to the Expression Controlling Means of Automatic Musical Instruments.
Inventor: MORITZ FRIEDRICH
Filed: 1912-01-25
Granted: 1913-02-25
Abstract: 2025. Moritz, F. Jan. 25. Actions; expression, controlling; tracker-bars. -Each striking - pneumatic is divided bv a flexible partition into two chambers, which normally communicate with each other and are controlled by separate tracker-ducts and valves. One chamber only of a pneumatic is connected to low tension exhaust to play a piano note. The second chamber may be connected to a high-tension wind-chest. Very loud notes may thus be played simultaneously with piano notes. The connexion between the chambers of a pneumatic is closed by an automatically-operated valve when a note is sounded. Special constructions of tracker-bars and valves are described. As shown in Figs. 1 and 9, the trackerbar 1 is provided with auxiliary ducts 17, one of which is provided for each of the ordinary ducts 2. Small ducts 41 may also be provided to counteract the effect of the bleed-holes 20 prior to the operation of the valves 22. Two auxiliary ducts of smaller area may be provided for each note instead of a single duct 17, the auxiliary ducts being connected by inclined passages to the channel 18. The striking-pneumatic is divided into chambers 14, 15 by a flexible partition 13. The chambers 14,15 normally communicate through a channel 27. When a narrow tune-sheet aperture passes over the tracker-bar 1, the duct 2 is exposed, causing the valve 8 to connect the chambers 14 through the channel 12 to the wind-chest 5. The valve 29, Fig. 3, which is freely mounted on the lever 28, is sucked on to its seating and closes the channel 27, Fig. 1. If the exhaust from the wind-chest 5 is throttled, a piano note is thus sounded. To sound a loud note, a wide tunesheet aperture exposes the tracker-ducts 2, 17, causing the operation of the valves 8, 22. The chambers 14, 15 are thus connected to the windchests 5, 21 respectively. The valves 29, 30, which normally balance the lever 28, close by suction. The valve 30 closes the atmospheric connexion 32 of the chamber 15, and the valve 29 closes the channel 27 so that the wind-chests 5, 21 are.not connected. A loud note is thus sounded, the exhaust in the wind-chest 21 being unthrottled. The valves are formed of rings 39 of aluminium or other light material, covered by disks 38 of india-rubber which overlap the peripheries of the rings. Fig. 5 represents a modification of the valve 29, the pin 36, which is secured to the lever 28, acting as a guide for the valve. India-rubber rings 40 are provided on the valve-seatings. A valve such as 8 or 22 is formed by securing two rubbercovered rings 39 to a threaded stem by means of nuts. A washer is interposed between the rings 39.

Title: Improved Electro-magnetic Speed Varying and Reversing Gear.
Inventor: BRUKWICKI BRONISLAW
IPC: H02K51/00

Granted: 1913-01-30
Abstract: 4458. Brukwicki, B. Feb. 22. No Patent granted (Sealing fee not paid). Electro - magnetic clutches. - In an electromagnetic clutch giving a continuous speedrange in either direction, currents are produced in the short-circuited winding H of an iron mass D, E on the driving-shaft F by the sum or difference of the electromotive forces induced by a stationary electro-magnet B and a magnet A which rotates with the driven shaft G. The magnet B has a winding, like an armature winding, connected to a fixed commutator k, and the magnet A has coils w giving the same pole-number as that of the magnet B. Both windings are excited from an external source which is connected to fixed slip-rings l, l<1>, and the commutator brushes rotate with the magnet A so as to cause the poles of the magnet B to rotate synchronously with the magnet A. The electromotive forces induced in the winding H by the slip due to the load are opposed by those due to the magnet B, so that by regulating the pole strength of the latter, as by means of a rheostat R, the speed of the shaft G may be controlled or reversed. With the exciting current in one of the magnets reversed, so that similar poles are adjacent, the currents in the winding H are due to the sum of the effects of the two magnets, and the shaft G rotates at a higher speed than the driving-shiaft F, at a speed which may be controlled by the rheostat R. The magnet B and the commutator may rotate with the shaft G, in which case the magnet A is fixed. The two parts D, E of the iron mass may alternatively be replaced by two separate laminated cores keyed on a common shaft and having a common short-circuited winding. The device is stated to be particularly suited for use with marine turbines and power-driven vehicles and vessels.
