Title: Improved Mechanism for Regulating the Force of a Transmitted Blow, applicable to Mechanical Hammers, Stamp Presses and the like.
Inventor: DENIS LUC LEON BASILE
Filed: 1904-05-31
Granted: 1905-05-31
Abstract: 12,367. Denis, L. L. B. May 31. Hammers, power ; stamping.-In power hammers, stamping-presses, and similar machines which are driven from a crank shaft by a pin-and-slot mechanism, the slot f has an incurved portion z, Fig. 2, so that the pressure of the slot on the crank-roller e does not prevent the tool a, Fig. 1, from delivering a free blow. Since, at the top of the stroke, the roller bears on the bottom of the slot, the roller will enter the in curved portion only on the latter portion of the descending stroke. A cover-plate p serves to adjust the size of the incurved portion and so to adjust the strength of the blow. The slot is fitted to a sleeve which is frictionally attached to the tool spindle. Figs. 11 and 13 show a machine in which the slot is traced on a spherical surface to give the portion c a rocking action about the shaft 1. The rocking action is transmitted by a link 4 to the tube 7 frictionally fixed to the reciprocating head of the machine. A spring 10 is provided to take up shock. In this case, the coverplate p takes the form of a circular sector pivoted at the centre of the sphere and operated by a link from a sleeve 17 on the shaft 1. In Fig. 14, the rocking action of the shaft 1 is made to give a vertical reciprocating motion to the hammer head a. The lever 27 turns on an oblique axis 28 carried by a sleeve with two heads 29. The sleeve is turned with the shaft 1 by the finger 30 sliding in the higher head of the part 29, and by suitable proportion of the parts an approximate straight-line motion is obtained. The application of the rocking shaft 1 for driving screw presses is also described, and Fig. 24 shows a trip hammer, the slot f being made in an arm pivoted at the centre 54, about which centre the hammer a rocks.

Title: Improved Apparatus for Raising Water by Air Pressure.
Inventor: SMITH ANDREW
Filed: 1905-03-28
Granted: 1906-01-04
Abstract: 6528. Smith, A. March 28. Direct air-pressure apparatus.-Relates to waterraising apparatus of the type in which two chambers mounted side by side are alternately filled and emptied under the action of compressed air admitted from a three-way cock controlled by a float in a separate chamber. Fig. 1 shows a sectional elevation of the apparatus, and Fig. 2 a plan partly in section. The two chambers A, B are provided with partitions H passing nearly to the bottom and forming separate chambers I, within which work float valves L, N for controlling the compressed-air valve F. Assuming both tanks to be full, the apparatus is started by admitting compressed air from the pipe E to the pipe E<1> whereby the water is expelled from the tank A through the discharge pipe D<1>. As soon as the water in the main part of the tank has fallen to the level shown in Fig. 1, the water in the chamber I, which until now has been unable to escape, rapidly falls and thereby actuates the float valves L, N which, respectively, admit compressed air from the chamber A to the chamber I and from the chamber I to a pipe M. This pipe conducts the air to a small cylinder 0 within which works a piston P connected to the air valve F, which is operated so as to admit compressed air to the chamber B. The air in the chamber A escapes through a hole Q, which is uncovered by the piston P, so that the chamber fills with water again in the usual manner, the action becoming automatic.

Patent GB-190511614-A (GB)
Title: Improvements in or relating to Controlling Devices for use in the Electrical Propulsion of Vehicles or Trains of Vehicles.
Inventor: RAWORTH JOHN SMITH
Filed: 1905-06-02
Granted: 1906-04-19
Abstract: 11,614. Raworth, J. S. June 2. Switches.-Motors for driving vehicles are automatically accelerated by the movement of a motor-driven rheostat giving a step-by-step motion, means being provided so that the driver can stop the acceleration. The arrangement is stated to be an improvement on that described in Specifications Nos. 5494 and 22,551, A.D. 1903. The barrel of the rheostat is supported on the shaft 7, and is provided with magnetic blow-outs. The shaft 7 also carries a ratchet-wheel 9, which controls the movement of the drum and is moved by a pawl 8 pivoted to a lever 6. This lever is loosely mounted on the shaft 7 and is connected by a pin 4, slot 5, and other gearing 3 to the electromotor 2. A pawl 11 is pivoted to a fixed standard 11<b> and prevents the wheel 9 from coming back under the action of the spring. The rotation of the armature of the motor 2 gives the lever 6 an oscillating motion. The bar of the main switch is connected by a rod 14 to a sleeve 12 on a carrier 13, which may be moved under the pawls 8, 11 to render them inoperative. The ratchetwheel is provided with teeth on a part of its circumference only, to prevent the barrel from making a complete revolution. When starting, the first operation closes the field circuit and unlocks the brakes. The next releases the brakes, and the motion of the lever 15 causes the sleeve 12 to be moved to the position shown in Fig. 1, freeing the pawls 8, 11. The vehicle or train starts and the motor 2 oscillates the pawl 8, causing the wheel 9 and barrel to revolve to cut resistance out from the armature circuit. The acceleration may be stopped by the driver diverting some of the field current through the electromagnet 17, which attracts its core 18 and disengages the pawl 8 from the ratchet-wheel 9. When all resistance is cut, out, the fields are diminished. The operations are reversed for stopping ; putting on the brake causes the lever 15 to open the main switch and moves the sleeve 12 to a position under the pawls 8, 11.. This disengages the pawls'and allows the spring to rotate the barrel to put resistance in the armature circuit.
