Title: Improvements in Friction Clutches and Couplings.
Inventor: BRIDGE ROBERT
Filed: 1902-04-09
Granted: 1903-02-12
Abstract: 8228. Bridge, R., and Bridge, J. April 9. Clutches, friction. Relates to detail improvements in the disc or plate type of clutch, in which one or more sets of discs give a frictional drive by reason of a face-to-face contact of the discs. The shell or disc a is formed with the extended boss a' which, strengthened with webs, may be mounted on a bush. The other half of the clutch consists of the annular plate c, which slides upon an irregular sleeve d as, for instance, one formed with two flats keyed on the shaft. The plate c is advanced or retracted by bell-crank levers pivoted at points g<1> to the sleeve. Their free ends are engaged by the collars h, the positions of which are adjustable upon the studs which carry them. The bell-crank levers are so fitted that, when the clutch is in action, the licks j assume practically vertical positions. By means of the cheek nut h<2> which forms a part of the collar, the position of the latter may be secured after adjustment. Preferably the inner face of the movable disc is fitted at intervals with wooden lags l dovetailed into place ; or the face of the shell may be so supplied. In other instances, leather, copper, paper, or fibre may be used or a metal-to-metal contact employed. According to the Provisional Specification, when more than one disc is employed, springs may be fitted to separate the discs on disengaging the clutch. Further, two discs carried within a shell may be mounted upon the shaft to act upon a face-plate formed in one with a boss revolving with the shaft, the discs being operated by right and left handed screws.

Title: Improvements connected with Coin Freed Gas Meters.
Inventor: GLOVER THOMAS
Filed: 1902-06-12
Granted: 1903-04-30
Abstract: 13,367. Glover, T. June 12. Gas meters; fraud, preventing.- Relates to the kind of apparatus described in Specification No. 25,272, A.D. 1894, in which the coin forms a connection between a handle disc and a wheel on the operating-shaft ; the object being to prevent the toothed wheel P from being moved by any instrument except a coin. A catch or bolt C is arranged on the stop A, which limits the motion of the coin pocket B. As the ring E is turned to bring its slot in line with a slot in the handle disc I, a projection F acts on the catch or bolt C, and forces it into engagement with the wheel P, which is thus locked in place, while the two slots coincide, and so prevents the wheel from being actuated by a tool placed through the slot R.

Title: Improvements in Lighting Arresters.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-05-21
Granted: 1904-03-24
Abstract: 11,649. Carolan, E. A., [General Electric Co.]. May 21. Lightning-arresters.-The reactive discharge in a series of arresters is controlled by shunting them and providing a common earth connection. In Fig. 1, two arresters are shown connected to the lines at 7 and to the earth at 12. The base 1 of insulating-material has a central partition 2 projecting upwards, and fitted with screw holes 3. On either side are non-inductive resistances 4 supported by clips 5, 6. The clips 5 are connected through binding-screws 7 to the line-wires, and the clips 6 are connected to metal cylinders 9 by metal strips 8 and thence through the air gaps between 9, 10, 11 to the earth-connection binding-screws 12. In case more than one set of cylinders 10 are used, the cylinder 11 separates the last pair. In order that the reactive discharge may traverse the arresters without passing through their total resistance, the shunt conductor strip 14 bridges the middle pair of conductors 10, thus ensuring that there are as many gaps in the path of the reaction discharge from line to line as there are gaps in either path of the discharge from line to ground.

Abstract: 13,820. Krupp Akt.-Ges., F. July 23, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Couplings, automatic.- Relates to means for operating automatic couplings. Fig. 3 is a section on the line 3-3 in the front elevation Fig. 1. Fig. 4 shows the cam and locking-plate on a larger scale. The hook A is shown locked in the usual way by a spring-supported finger B pivoted at B<1>, and rigidly connected to the releasing-lever D, which is actuated by the chain K. The chain is attached to an arm H on a sleeve which is loose on the transverse shaft E, operated by handles G at either side of the car. Rotation of the sleeve and lever H is only possible when the spring bolt N is disengaged from the slots m<1>, m<2> of the locking-disc M, which is fast on the sleeve. The bolt rests on the cam P, which is rigid on the shaft E and has a projection p<3> engaging a recess m<3> in the plate M. The cam and plate are so arranged that, when the handle G is rotated as indicated by the arrow, the bolt just clears the slot m<1> when the projection p<3> strikes the lower edge of the recess m<3>. Further rotation turns the plate M and sleeve, and the arm H tightens the chain which draws back the finger B, releasing the coupling. The slot m<2> and depression p<2> on the cam then allow the bolt N to descend and hold the coupling in the unlocked position. The coupling is locked again by turning either handle back to the position shown.
Patent GB-190414014-A (GB)
Title: Improvements in the Manufacture of Barbituric Acids and Intermediate Products.
Inventor: BOEHM FREDERICK
Filed: 1904-06-21
Granted: 1905-05-25
Abstract: 14,014. Boehm, F., [Merck, E.]. June 21. Barbituric acids; pyrimidines; malonylamides; ureides.-Relates to the preparation of dialkylbarbituric acids, and of intermediate compounds such as dialkylmalonaminic esters, dialkylmalonyldiamides, dialkylmalonurylamides, and mono-, di-, and tri-iminodialkylpyrimidines. The malonaminic esters and amides are prepared by hydrolysing cyandialkylacetic esters, cyandialkylacetamides, and cyandialkyl-acetylureides by means of mineral acids. In examples, diethylmalonaminic ester (C2H5)2ÀCÀ (COÀNH2)À(CO2C2H5) is produced from cyandiethylacetic ester, diethyl-, dipropyl-, and dibenzylmalonyldiamide from the corresponding cyanacetamides, diethylmalonurylamide (C2H5)2C(COÀNH2)À (COÀNHÀCOÀNH2) from diethylcyanacetylureide. Diethylbarbituric acid is produced by heating dietbylmalonaminic ester with urea and an alcoholig solution of sodium. By the condensation of urea. alkyl ureas, or acidyl ureas with dicyan compounds such as dialkylated malonitriles, 5- alkylated-4 : 6-diiminobarbituric acids or their N-alkylated derivatives are obtained. If the urea be replaced with guanidine or its alkyl or acyl derivatives, analogous products are obtained from dialkylmalonic esters, dialkylmalonaminic compounds, alkylated malonitriles, or dialkylmalonyl chlorides. In examples, diethyl- or dipropylmalonic ester is condensed with guanidine in an alcoholic sodium solution, or similar condensing agent, to form diethyl- or dipropyl-2-iminobarbituric acid. 5 Diethyl-2 : 4 : 6-triiminopyrimidine, or other alkyl derivative, is obtained by condensing guanidine with diethyl or other alkyl malonitrile. These imino derivatives are converted into barbituric acids by treatment with acid reagents which extract ammonia. According to the Provisional Specification, the urea or guanidine may be replaced by thiourea, corresponding thio derivatives being obtained.
