Title: Improvements in or connected with Percussion Fuses for Exploding Shells.
Inventor: REICHWALD AUGUST
Filed: 1901-06-14
Granted: 1902-03-27
Abstract: 12,172. Reichwald, A., [Krupp, F.]. June 14. Fuzes for projectiles.-Consists in making percussion fuzes so that they can be set either to act immediately upon impact or only after a certain interval of time. In the form shown in Fig. 1, the passage H conducts the flash directly to the bursting-charge through the passage L, or the fuze can be rotated to bring the passage H opposite to the passage M containing slow-burning powder. The fuze is locked in either of its two set positions by a spring bolt Q. In the form shown in Fig. 3, the flash normally goes through the passages K, S, T, 0, but, on blocking the passage S, by the insertion of a screw, the flash is directed through the slow-burning powder carried in the passage U.

Granted: 1903-09-17
Abstract: 1771. Reinold, H. F. Jan. 24. Stapling; staples, making. Relates to a machine for fixing tufts of bristles into the stocks of brushes &c. by means of wire staples. The wire 35 for the staple is fed from the reel 36 by feed rolls 37, 38. The roll 38 is operated by pawl and ratchet mechanism connected by the adjustable link 47 to the lever 50, the triangular end 52 of which is rocked by the pins 55, 56 on the drum 57 on the mainshaft 11. The length of wire is cut off by a knife 40 fixed to one of the bending wings 5, 6 of the vertically-reciprocating staple former 1. The former 1 is connected to the sliding bar 15 actuated by the cam 13. Adjustment of the bar 15 and former is effected by a screw 19. The wire is bent over the anvil 21 by the wings 5, 6, and is driven down the nozzle 3 along with the tuft of bristles t, Fig. 11, by means of the driver rod 2 connected to the crosshead 7. The anvil 21 is carried by a lever 22 pivoted at 23 and acted on by a spring 27 to normally withdraw the anvil. The anvil is thrust into position by a projection 32 on the bar 15. This projection acts on another projection 34 on the lever 24 pivoted at 23. When the lever 24 is forced outwards it carries the lever 22 with it by reason of the pin 26. As the projection 32 rises it draws the lever 24 inwards, extending the spring 25. The stock is pressed against the nozzle 3 by an adjustable sector plate carried by a vertically-sliding bar which is connected by links to the crosshead 7.

Title: Improvements in Mechanism adapted more particularly for Operating Railway Switches.
Inventor: SYKES WILLIAM ROBERT
Filed: 1903-05-08
Granted: 1904-05-07
Abstract: 10,503. Sykes, W. R. May 8. Points and switches.-A "butterfly" or selflocking combination of two levers, in which one lever moves the other through a certain arc and then retains it there, is so constructed that an increased relative motion of the actuated lever is obtained, and this is applied to directly actuate railway points. Fig. 1 is a plan of the levers in their mid position. Instead of the " driving " end of the lever A and the corresponding " driven " end of the lever B being in a single plane, each is split into two members so that the member A' of the lever A acts on the wing B' of the butterfly lever B, while the member A<2>, which is underneath the wing B' in the figure, acts on the wing B<2> which is underneath the member A. In this way, the working width of the end of the lever A is virtually reduced to zero and the angle through which the lever B turns correspondingly increased ; or, for a given motion of lever B, a lever arm of proportionately less radius and greater power can be used on the lever A. Locking is effected in the usual way by the surface e of the member A' coming into contact with the surface f of the ring B'. Fig. 4 shows a butterfly lever of ordinary construction applied to actuate a bar G connected to a railway switch. In this case, a notch is made between the wings B<1>, B<2> to receive the lever A. With the above improved construction of lever, the lever A could be shortened and consequently less power required to actuate the switch.

Title: Manufacture of a Black Sulphurised Dyestuff.
Inventor: IMRAY OLIVER
Filed: 1903-06-10
Granted: 1903-07-16
Abstract: 13,035. Imray, 0., [Soc. of Cliemical Industry in Basle]. June 10. Dyes, artificial.-Relates to an improvement on the processes for making sulphurized dye-stuffs which dye unmordanted cotton black, described in British Specifications Nos. 16,449 and 19,831, A.D. 1896, and No. 1151, A.D. 1900. According to this process, dinitrophenol [OH : NO2 : NO2= 1 : 2 : 4] is melted with alkali sulphide and sulphur at a moderate temperature, viz. 115‹ to 140‹ C., and under such conditions that the mass does not become dry until the formation of the dye-stuff is complete. The process, which usually lasts 4 to 6 hours, is shortened by raising the temperature, the shade also becoming more greenish or bluish. The shade may also be made more greenishblack by the addition of copper or its salts, or about 5 per cent. of dinitro-chlorbenzene. The operation may be carried out in an open vessel, in a closed vessel under pressure, or in a vessel having a closed or open reflux condenser. Or the water may be evaporated in stages at 130‹-140‹ C., the temperature being maintained until the process is finished.

Title: Improvements in Automatic-feed Weighers.
Inventor: LEETHAM SIDNEY
Filed: 1904-02-19
Granted: 1905-01-12
Abstract: 4215. Leetham, S., and Leetham, R. E. Feb. 19. Automatic -f e e d weighers. - A sack or other receptacle is shaken during the time that it is filled to about #ths of the total amount, and the shaking is then stopped while the filling is completed. The proper proportion (#ths say) of the weights are added to the pan m, while the remainder are added to the upper pan w. When the load in the scale - pan m exceeds that in the receptacle t, t h e beam a, Figs. 1 and 2, moves down at the weighted side, and depresses by the rod c the toggle d into a straightened position, and thus forces back the weighted lever e and with it a sliding bar g carrying a belt fork h. The belt is thereby shifted from the loose pulley i to the pulley k fast on the shaft l, l, and the arm n revolves. The roller o attached to the free end of the arm strikes, as it revolves, against the arm q, pivoted at r or v and carrying a roller s, which strikes the sack t, the arm being brought back to its initial position by the spring p. As soon as the required proportion is weighed, the pan m and its supporting - rod, which passes freely through the pan wand carries a collar x, are raised, and the collar x comes into contact with the pan w, and the upward motion ceases. This motion is sufficient, however, to release the toggle d and shift the belt to the loose pulley while the weighing is completed. The spring p may be dispensed with by making the arm q in the form of a bent bar and utilizing its end as a striker. The striker is shown in different form actuated by a tappet or by means of a crank and connecting- rod. The sack also may rest on a platform which is vertically displaced, or which is fixed while the sack is lifted by a forked arm, the platform, as soon as the weighing is partially completed, being thrown out of contact with a support, and the sack suspended freely from the arm. An oscillating vertical shaft, carrying a fork which embraces the sack, may be also used to shake the contents of the sack. The depression of the beam may cause an electric switch to couple the shaft l with a motor.
