Abstract: 228. Sindeband, M. L., and Woticky, C. B. Jan. 3, 1911, [Convention date]. Electrical s y s t e m s, automatic; track appar a t u s for stopping trains. - An electrom a g n e t controlling train - stopping apparatus is connected in circuit with an alternator and a coil on the train which coacts inductively with the track rails. which are so connected that the reaction effects on the train circuit vary according to the state of the track to stop the train in case of danger. The train apparatus is shown in Fig, 5, and may he used in conjunction w i t h either of s e v e r a arrangements of track circuit which are described. The track rails may he electrically continuous, or insulated track sections may be connected through condensers or transformer coils, or track relays 15 and batteries 16, as shown in Fig. 1, may be used. In this arrangement, a train 18 in section 12 de-energizes the relay 15, which then connects the track rails of section 11 through the condenser 17. These rails and condenser form the secondary coil to the coil 31 carried on the train. The train apparatus may include only an alternator driven at constant speed, a regulating-resistance 42, an ammeter coil 31 with an indicating-lamp 40 in shunt therewith, and solenoid 43. The core of solenoid 43 is held in a mid position under normal conditions by the coil and a spring. If the current diminishes or increases beyond fixed limits the toggle joint 45 is opened out and the lever 53 connected to the controlling-apparatus is actuated. If the advance section is occupied, the track circuit is substantially short-circuited and an excessive current flows in the train circuit, thereby causing a large current in the solenoid 43. Fig. 5 shows an engine apparatus arranged with a generator 36 driven at a speed proportional to train speed, so that the overload condition necessary for energizing the solenoid 43 is reached with a second train at a distance proportional to the speed of the first. When the speed drops below a minimum limit, the battery 61 is put in circuit with the solenoid 43 by the centrifugal switch 62 to prevent actuation of the brakes.

Granted: 1912-04-11
Abstract: 5320. Soc. R. Bourbeau et H. Devaux. March 18, 1911, [Convention date]. Expanding pulleys having stepped cheeks are rendered automatically variable. A fixed cheek a has a boss a<1> secured to a driving-shaft b. The other cheek c has a boss c<1> sliding on the boss a<1>. These cheeks have parallel parts d, e forming steps to support the belt when running. At the far end of the boss a<1> is secured an annular cam f against which rest the outer ends of a set of rods g, Fig. 3. The rods g are surrounded by an elastic member h and their inner ends engage an annular groove in the back of the cheek c. When the belt m is on the larger pulley step, the cheek c is kept from moving outwards by the rods g, which are pressed against the boss c<1> by the member h. The gear then transmits power at its higher speed. If the resistance increases, the wedging action of the belt causes the outer ends of the rods g to ride up on the cam f, and so allow the belt to drop on to the smaller pulley step. The pulley may be locked in this position by a pin projecting from the boss a' into an L-shaped groove k, Fig. 4, in the boss c'. To unlock the pulley and allow the gear to be raised automatically, the engine is slowed down to enable the pin j to slide out of the transverse part k<1> of the slot k. The rods g are supported by tapered studs il.

Filed: 1912-09-30
Granted: 1913-12-30
Abstract: 22,212. Smith, O. A. Sept. 30. Screwing; screwing dies and die-heads.-A selfopening die-head has means to release the dies only after the last thread has been cut without mutilation of it or the adjacent shoulder. The die head 2, Figs. 2 and 3, has radial undercut slots 4 to carry the dies each fixed to a base-plate 9, Fig. 11, with side pins 10, this baseÀplate engaging the undercut in the slot to prevent the die from lifting and being spring-pressed to disengage the die. Adapted to engage holes in the head are sleeves with enlarged heads 24 adapted to abut against the front surface of a cam-ring 16, which is mounted on the boss 3 of the head and retained in position by a cover-plate 19, into which the securing-bolts 22 passing through the headed sleeves are screwed. The back surface of each die is tapered transversely throughout its length but is only tapered partly in an axial direction, so that after the dies are closed any slight movement of the cam-ring does not affect the jaws. For adjustment of the pass of the dies, a screw 26 in the cover cap 19 has a recessed central portion adapted to engage a projection 28 on the cam-ring, so that as the screw is turned after the bolts 22 have been loosened, the cam-ring is rotated relatively to the die head. The boss 3 of the die bead is hollow and adapted to receive a boss 34 on a part 32 fixed to the turret of the machine, a fixed ring 29 being mounted between the cover-plate 19 and a fixed collar 33 and spring bolts 36 allowing a loose ennnexion between the cover-plate and the fixed ring. The fixed ring is split and has mounted in the split a lever 30, the bottom of which engages a notch 31 in the boss of the die head. After the motion of the turret has been caused to cease by a stop during screwing, the die head, die ring, and cover-plate are drawn forwards owing to the friction of screwing being greater than the initial resistance of the springs 39, but as the springs are compressed, the coverplate 19 and die ring are retracted, the die head still going forwards so that the dies are released and opened by the springs 11. Instead of spring bolts 36, shortened bolts may be used, the heads of which come against the fixed ring 29 after the head has moved forwards a certain distance, thus stopping the forward motion of the cam-ring. Reference has been directed by the Comptroller to Specification 8454/97.
