Title: Improvements in Advertising Clocks.
Inventor: MCDONALD GEORGE
Filed: 1904-12-31
Granted: 1905-02-09
Abstract: 29,229. McDonald, G., and Kenyon, G. W. Dec. 31. Clocks combined with advertising - apparatus.- Relates to an advertising- clock, in which the timepiece controls the display of the advertisements. Fig. 1 shows the clock with the advertisementcarrying drum below. On the fourth or other suitable wheel c of the timepiece are fixed four pins c<1>, equally spaced apart and acting in turn upon the short arm d<1> of a lever d. The lever d is connected by a cord, wire, or chain e to a lever f, of such length that very little power is required to operate it. The lever f moves between stops g, g<1>, and is pivoted at h by a spindle with which it rotates. Its shorter end f<1>, when in the position f<2> shown in Figs. 3 and 6, prevents the detent lever i from rotating. The clockwork train j operating the drum a is thus stopped until the lever f comes into the position shown in Fig. 5, when the detent i is released and makes half a revolution until it meets the stop l. The pin c<1> is then about half-way along the arm d<1> ; when the arm d' is released, the lever f descends, and its end f rises, and through the spindle hand links m, m<1> lifts the stop l. The detent i is thus released, and rotates until it again engages the end f <1>, when the process is repeated. The advertisements are mounted on the drum a by means of cards p on wires p<1>, the ends of which pass through holes q in the end discs q<1> of the drum, these holes q being so spaced apart that the halfrevolution of the detent i allows the train j sufficient motion to change the displayed advertisement. The advertising-mechanism is driven by a spring preferably a little stronger than those generally used in clockwork.

Title: Improvements in the Manufacture of Armour Plates for the Protection of Ships and other Steel Objects.
Filed: 1906-08-09
Granted: 1907-08-08
Abstract: 17,935. Marks, E. C. R., [Soc. Anon. Italiana G. Ansaldo, Armstrong, & Co.]. Aug. 9. Armour and armour-plating.--Armour-plates are made of steel with layers of different physical properties obtained by a series of carbonizations and decarbonizations. Ordinary, ternary, or quaternary steel plates &c., before or after they have been mechanically manipulated, are first carbonized by heating with granular carbonaceous substance pressed against them or in an atmosphere of carbonized gas. The duration of treatment depends on the depth of carbonization desired. The decarbouization is obtained by heating the plates with metallic oxides in a divided state pressed against them until a desired depth is reached. These alternate processes may be continued many times. On subsequent tempering, the plate attains different physical properties in the various layers.

Title: Improvements in the Manufacture of Stable Hydrosulphites.
Inventor: JOHNSON JAMES YATE
Filed: 1906-10-11
Granted: 1907-04-11
Abstract: 22,525. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Oct. 11. Hyposulphites.-Relates to the invention described in Specification No. 23,515, A.D. 1904, in which hyposulphites are obtained free from water of crystallization. According to this invention, this result is obtained by treating solutions of the salts, while cold, with caustic alkali of such a strength that the concentration of the alkali in the final liquid is not less than twenty-five per cent, the concentration of the caustic alkali being greater the lower the temperature. If at any part of the operation, there is too little alkali present, hydrated hypo sulphite is precipitated, but this loses its water of crystallization after a time if sufficient alkali is added. The hyposulphite may be filtered with suction, washed with alcohol or the like, and dried in vacuo at a temperature of 50-60‹ C. In an example, one volume of strong sodium hyposulphite solution is slowly added with stirring to form one to one and a half volumes of fifty per cent caustic-soda solution, at the same time cooling so that the temperature does not exceed 20‹ C. The precipitate is washed and dried, as above. If the caustic-soda solution is added to the hyposulphite solution, hydrated hyposulphite is at first precipitated, but this gradually loses its water of crystallization. Instead of caustic-soda solution, the equivalent quantity of solid caustic soda may be used.

Patent GB-190801967-A (GB)
Title: Improvements in Saw Filing Machines.
Inventor: HOLMES WILLIAM JOHN
Filed: 1908-01-28
Granted: 1908-12-03
Abstract: 1967. Holmes, W. J. Jan. 28. Saws, sharpening.-In a machine for filing cross-cut or rip saws the driving-shaft B carries at one end a cam B', which has a pin B3 engaging a slotted piece E', which is attached to a plate E carrying a file F so as to reciprocate it in guides in a slotted cross-head D, which is capable of being pivoted on the driving-shaft. The saw, which may be of any width or may vary in width, is clamped between bars J, which are mounted between channel pieces J3, J<4>, the piece J<3> carrying a spring J<5> engaged by a screw J<8> in a bracket J<6> fixed to the piece J<4>, the channel pieces pressing on the blade so as to fix the saw in position during the filing operation. The saw is fed along by a spring- pressed pawl engaging the teeth, which is mounted at any position, according to the amount of feed, in slots at either end of a bar L, which is reciprocated in ways A<8> by a cam B<2> mounted between projections L<2> on the bar. During the down-stroke of the file, the pawl rides up on to one of the plates L<7> and is disengaged from the teeth. To advance and retract the saw towards and from the file the sawholder carries rods I passing through guides A<7> and carrying a cross-bar I' mounted loosely on the shaft B. To the shaft is fixed a sleeve I<11> having' shoulders to engage a pin I<13> projecting from a loose sleeve I<9> carrying a face cam I' abutting against a-pin on the cross-bar. The saw-holder is thus retracted and is returned by springs I<15>. To vary the pressure of the saw on the file the ends of the springs may abut nuts on the rods I, and, to regulate the distance of the holder away from the file, compression springs K extend between the bearing I<17> and a washer, the end of the rod having a thumb-nut. When filing rip saws, the cross-head is kept in a vertical position, a crank-pin G<3> which engages the slot being directly under the countershaft G, but when filing cross-cut saws the crosshead is alternately swung to the angular positions shown in Fig. 5. The crank-pin G<3> and with it the cross-head are moved along the dovetail slot in the crank G<1>. The oscillation is produced by a notched wheel M, connected to the shaft B by a pin O and collar O<1> and carrying two rollers M<1> engaging a wheel M<3> provided with diagonal slots and intermediate arc-shaped recesses. The sides 2, 3, Fig. 7, of the teeth are thus filed, and, by revering the rotation of the shaft and by the use of the loose sleeves 19, O<1>, the time of the up-stroke in relation to the other parts of the mechanism is reversed, and the sides 4, 5 of the teeth filed.
