IPC: B21B39/04
Filed: 1932-05-09
Abstract: 390,963. Master control of several motors. AMERICAN SHEET & TIN PLATE CO., Frick Building, 5th Avenue, Pittsburg, U.S.A.-(Assignees of Mollvried, H. G. ; North Hills Estate, Ross Township, Pennsylvania, Moore, C. E. ; Gary, and Peterson, R. E. ; Aetna, both in Indiana, both in U.S.A.) May 9, 1932, No. 13370. Convention date, Dec. 15, 1931. [Class 38 (iii).] Travelling between predetermined limits.- Sheet metal or packs are delivered from a furnace D to a chain feed table B where they pass through rolls A to a catch table C, both tables being automatically tilted to pass the sheet over the top of the rolls back to the feed table and so pass through the rolls again as often as required. The operator moves controller 2 to the right to complete a circuit for coil 3c of forward contactor X which -closes the forward circuit to the conveyer chain motors 200 of tables B, C which feed the sheet or pack through the mill. The pack then trips a trigger operating a switch T so that its contact 10 is opened and contact 12 is closed to energize relay 14 which opens contact 16 and closes contacts 24, 25, contact 25 closing before the closing circuit is broken through contact 16. When contacts 24, 25 are closed, contact 25 completes a maintaining circuit for relay 14 until the catch table C moves switch 22 to open contact 21. When the sheet leaves the trigger the switch T closes 10 and opens 12 thus operating relay 7 to reverse the circuit to the conveyer chain motors 200 and relay 32 is operated to complete circuit to the motor 202 which tilts up the catching table C until deenergized by a cam operating the switch 22 to hold the tilt table C up, thus conveying the pack back over the top of the rolls. The returning pack thus frees the trigger of switch T whereby the sheet is received, lowered, and fed through again. When rolled enough the controller 2 is operated to break the automatic return and feed the sheets off the table C to the right.

Title: Improvements in clockwork-driven current-impulse transmitters for alarm installations
IPC: G08B25/12
Filed: 1934-05-03
Abstract: 422,673. Actuation of switches. GILL, H. A., 51, Chancery Lane, London.-(Elektrozeit Akt.-Ges. ; 136, Mainzerlandstrasse, Frankfort-on-Main, Germany) May 3, 1934, No. 13424. [Class 38 (v)] A clockwork-driven current impulse transmitter has a shaft A adapted to be turned by a key, (not shown), to wind up a clockwork which drives through escapement mechanism, (not shown), a wheel R having cogs Z which on rotation engage an actuator f of a set of contact springs J to give a series of current impulses. Pivoted to the frame at B is a lever H having at the end of one limb a nose M engaging a depression N in a cam disc C fixed to the wheel R. The other arm of the lever H comprises a keyhole cover T, a projection u adapted to co-operate with a fixed stop pin x, and a lateral projection U. The lever H also carries a spring V whose end lies between projections X, Y on a member O fixed on the winding shaft and having an end v for engagement with a pin S on the wheel R. To give a signal, the key is inserted on to the shaft A and a projection on the key engages the opening Q on the member O which rotates in a clockwise direction to wind the clockwork until arrested by the stop pin x. During this movement the end v of the member O leaves the pin S and the projection Y on the member O engages the spring V thus tending to turn the lever H in an anticlockwise direction. The lever H is however restrained by the engagement of the keyhole cover T with the side of the key. When the key is withdrawn, the arm H is released and rotates to free the nose M from the recess N and the wheel R rotates one revolution to give the series of impulses by means of the teeth Z and member f. As the wheel R is rotating, the member O rotates anticlockwise and the projection X stresses the spring V so that the nose M engages the periphery of the cam C and enters the recess N at the end of the movement, which is terminated by the pin S engaging the end v of the member O. Thus it is impossible to release the clockwork, before the key is withdrawn, and the keyhole is covered during the return movement of the clockwork, so that faulty operation is impossible.

Title: Improvements in Automatic Small Arms.
Inventor: CHEVALLIER ARNOLD LOUIS
IPC: F41A5/20
Filed: 1918-08-19
Abstract: 131,705. Chevallier, A. L. Aug. 19, 1918. Breech-actions, sliding breech-block.-Relates to automatic small-arms of the type described in Specification 113,805, in which the breech-bolt is locked by a pair of spring-controlled levers held in engagement with the bolt by an inertia sleeve, and consists (1) in replacing this inertia sleeve by a locking-sleeve slidable on the 'band and loosely connected by a spring-controlled drive-rod to a forwardly-driven gas-operated muzzle-sleeve, (2) in a device whereby the return of the locking- sleeve, after the breech-opening movement, is delayed until the breech-bolt has returned to its locking position, and (3) is means for actuating the locking-sleeve by hand. In the form shown in sectional elevation in Fig. 1 and in plan in Fig. 2, the breech-bolt 2 is locked in the closed position by the claws z of a pair of levers x pivoted at 6 to the breech-casing n, the forward arms v being held in the outward position by the interposition of a locking-sleeve k slidably mounted on the barrel a, and loosely connected by a spring- controlled drive-rod l to a sleeve i slidable on a second sleeve b screwed to the muzzle of the gun, and rigidly connected to an inner slidable sleeve c. The sleeve c is driven forwardly by the gases on discharge and advances the sleeve k out of engagement with the levers x, whereupon the springs 3, which are carried on caps 4 pivoted to the body n, turn the levers out of engagement with the bolt 2 and permit its recoil. The drive-rod l during its forward movement carries with it an extension 21, a nose 25 on which engages a notch 25<a> on a lever 23 pivoted at 28 to the body n and urged upwards by springs 26; the sleeve k is thereby prevented from returning under the action of its spring into locking position between the levers x. On the lever 23 is pivoted a detent 29 which, when the lever 23 moves upwards to engage the nose 25 of extension 21, rises into the path of the breech-bolt 2, and is pressed down by the bolt on its return, thereby disengaging the nose 25 from the notch 25<a> and permitting the sleeve k to move into engagement with the levers x to lock the bolt. A lever 16, pivoted at 17 to the breech-body n, and carrying a pin 18 working in a slot 19 in the sleeve k, is provided for manual operation. The levers x are adapted to be readily detached from the body n when the caps 4 are swung outwards.

Title: An improved process and apparatus for the dispersion of solids in liquids
IPC: B02C7/10
Filed: 1926-05-29
Abstract: 276,728. Whatmough, W. H. May 29, 1926. Emulsions, making.-In the production of dispersions of solids in liquids, such as relatively large quantities of mineral pigments in water or oils, or in rendering homogeneous imperfect dispersions produced in colloid mills, independently rotated horizontal discs having non-coincident axes are employed, a substantial portion of the surfaces being in rubbing or smearing contact to produce the effect described in Specification 276,400. The upper disc is normally smaller than the lower one, and more than one upper disc may be employed. Non-circular discs or discs having eccentrically placed shafts may be used and provision may be made for adjusting the position of the axis of the upper or lower disc or the axes of both discs. Variation in direction or speed of the discs is effected by reversing clutches and change-speed gearing. To enhance the smearing effect. insertions or aprons of yielding or flexible material are applied to the discs, or part or all of one or both of the discs may be covered with these materials. Means are provided forfeeding the materials under pressure and the temperature may be varied. In the form shown in Fig. 1, the shaft 9 of the lower disc 8 is driven by bevel gearing through a gear box 24 from a motor 19, and the shaft 12 of the upper disc 11 from the same motor through a reversing clutch 35 and a gear box 29, the clearance between the two discs being adjusted by a crank-operated worm 44 and a worm-wheel 43 which supports a grooved collar 47 on the shaft 12 and is screwed to engage the casing. For cleaning purposes, the upper disc 11 can be raised by a forked lever 49. The materials to be operated on are delivered by a pivoted chute 51 to a central well 53 which rises with the disc when this is raised by the lever 49. Delivery of the treated material is effected by a guard ring 13 which is formed with a delivery chute and a wiper for the disc 8. To deal with coarse material, the inner edge of the well is bevelled at 55, or the disc 11 is made concave, or helical V-shaped grooves 57, Fig. 9, diminishing in depth and terminating before the edge of the disc is reached, are provided in the disc 11. Smearing or wiping is facilitated by inserting a band of yelding or flexible material near the edge of the upper disc or by the provision of a depending apron 58, Fig. 9, which is bolted to the disc 11. In a modification, the materials are delivered to the discs under pressure produced by closing in the well 53 round the shaft 12 which is made hollow and terminates in a funnel, the length of the shaft determining the pressure produced. Alternatively, the shaft 12 may be short and the materials forced through by external pressure. Additional smearing means, such as reciprocating grinding-bars, may be provided to make contact with the unoccupied parts of the larger disc. Specifications 266,098 and 276,727 are referred to.
