Title: Electric Apparatus for Regulating Clocks.
Inventor: RUDD ROBERT JAMES
Filed: 1898-09-12
Granted: 1899-09-12
Abstract: 19,337. Rudd, R. J. Sept. 12. Regulators; pendulums.-Occasional momentary electric currents from a standard timekeeper are employed to shift a lever a pivoted on a bracket b so as to alter the effective length of the pendulum spring c by means of the curb pins d in case the two clocks are not exactly synchronous. The action is brought about as follows :-From a joint e on the regulating-lever a a rod f hangs down through a loop g and against a supporting friction pawl h under a spring i. A snail l turning with the seconds hand determines the amount of movement given to the regulating-lever, because it limits the lift of a lever t which is thrown up against the hanging rod when the armature n of the electromagnet is attracted. The armature kicks a bell crank on the same pivot r as the lever, and the bell crank affects the lever through a C-spring s. In a modification, the regulating-lever affects the spring of an auxiliary pendulum which is connected by a spring to the main pendulum. The snail may be replaced by a pin-wheel, and the cam be formed on the contacting lever. A handlever is provided for setting the pin-wheel after setting the hands.

Abstract: 24,236. Lenton, L. Nov. 17. Tyres, pneumatic &c.-Relates to means for attaching tyres to rims and for manufacturing various parts of tyres from chamois leather. The leather is waterproofed by treating it with a weak solution of india-rubber in naphtha, and is then dressed with a similar but stronger solution. To construct the air tube, shown in section in Fig. 1, a strip 2 of the leather thus treated is stretched with its rough surface outwards round a mandrel. The overlapped edges 3 are solutioned together and to an inner rubber strip 4 and an outer rubberfabric strip 5, and the ends of the tube may be similarly joined together. The cover, shown in diagrammatic section in Fig. 3, comprises an outer leather strip 11 and a canvas lining 12, of which the contracted edges 13 receive bands 14 having tapes 15 and strips 16 solutioned thereto. The inner air tube may be protected from the edges of the cover by a flap 21 which is secured along one edge 22 to the cover and may be provided with a fold 23. The edges of the cover are slit along the lines 17, 18, shown in Fig. 6, to form tabs 20 which may be interlocked to secure the tyre to the rim. The same formation of edge may be applied to rubber tyres. If the inner air tube is dispensed with, the edges may have overlapping flaps which contract on to each other and may be smeared with viscous fluid to give an airtight joint. A tyre protector may be formed from a circum. ferential leather band provided with transverse strips.

Title: An Improved Oscillating Furnace Fire-grate.
Inventor: GOLBY FREDERICK WILLIAM
Filed: 1900-06-08
Granted: 1900-07-28
Abstract: 10,491. Golby, F. W., [Soc. Anon. pour l'Exploitation des Brevets H. J. Piron]. June 8. Firebars and grates.-The grates are preferably for locomotive and motor furnaces, and are oscillated by mechanical means, e.g. from the axle, through the lever 10, Fig. 1, which may be rendered stationary at either end and oscillated at the other end, so that the grate may be oscillated or not as desired. For stationary furnaces, the grate may be oscillated by the hand-lever 48, which rocks the bar 3, Fig. 5, and oscillates the firebars through the connecting-rods 5. To the lever 10 is linked the bar 8, Fig. 2, so that, when the pivot 11 of the lever 10 is rendered stationary by the brace or bridle 33 at the end of the rod 12, the grate is oscillated through the rods 6, 3, and 5. To stop the firegrate motion, the key 28 is turned back so that the pivot 11 can move along a guide in the bridle 33. The operating-rod 12 is supported by the platform of the locomotive or other furnace. The lever 10 has a central socket 13, into which runs the cam or block 14, the head of which engages in grooves in the collar 15 fixed on the axle. Cam-grooves on the collar 15, with passages through which the block 14 runs, cause the block to effect a to and fro movement in two revolutions of the axle. The firebars have bearers 41 with concave lower surfaces, as shown in Fig. 8, resting on projections 44, and are fitted with rings 40 whereby they may be readily handled and put in place. Each bar is furnished in the lower part of the suspended plate with a double bossage or contact-hammer 1, 2, so that all the bars may be oscillated together.

The shaft C carries the high-pressure piston B, and a combined intermediate and lowpressure piston E. The pistons have four symmetrically-arranged vanes b<1>, which work in annular chambers, formed in the casing and provided with rotating abutments D, G, G<1>. Toothed rings are secured to the pistons, and gear with corresponding toothed wheels on the abutments. The pressure on the abutments is balanced by providing them with peripheral steam spaces a<4>. The piston E is formed integral with the shaft, and a wearing-plate is fitted in the casing so that the piston B can be pressed against the plate by a nut c<2> on the reduced end of the shaft. The various shafts are journalled in bushings a<10>, provided with oil-rings a<11>, which are placed in recesses adapted to contain oil. The valve casing I contains three plug valves J, K, L, connected by suitable pipes to passages 1, 2, 3, 4 leading to the high - pressure cylinder, and to corresponding passages leading to the other cylinders. The steam supply enters the passage 13, and, after passing through the valve J and high-pressure cylinder, returns through the passage 14 to the valve J, from whence it passes through the other cylinders and valves in turn to the exhaust passage 22. The engine is reversed by reversing the valves, the spindles of which are connected together by links. By means of a subsidiary valve 0 in the centre of the plug valve J, the high-pressure cylinder can be rendered inoperative and steam admitted directly to the intermediate cylinder..

Title: Improvements in and connected with Photographic Changing Boxes, Developing and Fixing Apparatus.
Inventor: SCHOELZIG OTTO
Filed: 1900-09-12
Granted: 1901-10-12
Abstract: 16,238. Sch÷lzig, O., [Mayall, A. V.-C.]. Sept. 12. Change-boxes; dark slides; dark rooms, changing- bags, and the like; wrappers for packing plates and the like.-Relates to the packing of sensitized plates &c. and to means for removing the plates from their packages, exposing them one by one in the camera, and either packing them up again or developing and fixing them. The plates, covered and separated by sheets of cardboard as usual, are arranged in a pile with a strip of cardboard 4 round them. A sheet 15 of light-tight paper is pasted on the cardboard and folded over the pile, so that the pile may be removed from its box 1 and inserted into the magazine A without risk of exposure. The box 1 is placed in the receiver B and the lid 2 used as afterwards described. The magazine fits on the back of the camera and has a slide 19 which is raised for exposing the plate. After exposure the slide 19 is entirely removed, reversed so as to exhibit the word "exposed," and then shut down again. To ensure this reversal one lower corner of the slide is rounded and the other squared, the rounded corner alone being able to press back a catch. Double exposure of the same plate is thus prevented. The magazine is next fitted on to the receiver by the catch 20 and pin 23 &c. and turned horizontally. The slides 22, 19 of the receiver and magazine respectively are then drawn out together and the handle 28 controlling a pawl is turned. The pawl pushes the exposed plate into the bag 31, the spring catch 41, which held the end plate, giving way. The cardboard sheets before mentioned are removed in the same way. Catches prevent either slide from being raised until the magazine and receiver are fitted together. When all the plates are exposed the lid 2 is placed on the flange 42 and the box 1 containing the plates is forced into it. The receiver may be replaced by a box lighted by ruby windows, in which the plate, introduced from the magazine, may be developed and fixed. The requisite chemical solutions enter and leave the box by rubber tubes.
