Title: Improvements in Weighing Machines.
Inventor: POOLEY HENRY
Filed: 1903-10-08
Granted: 1904-10-08
Abstract: 21,599. Pooley, H. Oct. 8. Compound-lever apparatus ; indicating-mechanism; relieving-mechanism.-Two platform weighing-machines or weigh-bridges for large and small wagons or vehicles &c. are coupled up with a common indicating-apparatus, means being provided for connecting or disconnecting either of the machines without affecting the subsequent readings of the dial. The indicating-mechanism consists of a weighted body a which is suspended within a tank a', containing water or other liquid, from a lever b having fixed thereto a quadrant b<5> carrying a flexible chain, cord, or other connection b<4>, which passes round a pulley e mounted on a shaft e<1>. A pointer f moving round a dial g is fixed to the shaft e<1>. The short arm of the lever b communicates by a link d with a weighted forked lever q, both prongs of which rest in bearings q<1> and are each connected by links x<1>, x with the transferring-lever of a weigh-bridge. The weight of each weigh-bridge is balanced by forming the links x<1> with hooks x<2> for engaging two weighted levers i, the knife-edges i<2> of which rest on links k supported from a transverse bar k' carried in upright brackets on the cross-beam e<1>. One or other of the weigh-bridges is placed in and out of gear by operating a handle h<2>, on the shaft of which are fixed two tappets h. On turning the handle to the right or left, one of the levers i is depressed and lifts the corresponding link x<1> off the common lever q. The handle is locked in either position by means of a pin h<3> passing through it and holes in a ring h<4>. One of the weigh-bridges may be permanently connected to, and balanced from, the indicating-mechanism, the intermediate balancing-lever being dispensed with, if desired. In a modification, in which the balancing levers are omitted, the indicating-mechanism is adjusted on the disconnection of a weigh-bridge by varying the level of the liquid in the tank a' either by moving a simple displacing arrangement, or by withdrawing liquid, this adjustment being automatically effected by the movement of the disconnecting means, or the adjustment may be made by adding to, or taking off, a dead weight or spring pressure upon the weighted body a or upon its supporting-lever.

Title: Improvements in Apparatus for Transporting Loads.
Filed: 1904-02-15
Granted: 1904-04-14
Abstract: 3796. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. Feb. 15. Railways, systems of; electric railways; electric motor vehicles.- Consists in transporting loads both vertically and horizontally by means of a self-propelled vehicle capable of running on both vertical and horizontal tracks. In the arrangement described, there are two vertical shafts, the tracks in which are connected at the top and at the bottom by horizontal tracks, each of which has a branch extending away to any required distance from the shafts. The vehicles may be arranged to perform a continuous journey, running always up one shaft and down the other, and means may be fitted for automatically discharging the vehicles on the upper horizontal track and stopping them for loading on the lower track. Figs. 1 and 2 show the vehicle running on one of the vertical tracks. Its two receptacles a, b for the load and driver are pivoted so as always to hang vertically. The two electric or other motors c drive shafts, carrying pinions e, engaging racks fixed to the track and plain flanged wheels g, which, when the vehicle leaves the vertical shaft, run on the smooth rails forming the horizontal tracks. One electric motor only may be used, its armature being geared to one driving- shaft and its field magnets to the other. The two driving-shafts may then be fitted with brakes operated by weighted arms and so arranged that both brakes are off when the vehicle is on the vertical track, while, when the vehicle is on a horizontal track, the upper or inoperative shaft is braked. By this arrangement, the horizontal speed is double the vertical speed. This difference of speeds may also be obtained by making the rack pinions and flanged wheels of suitable relative diameter.

Title: The Manufacture of New Oxycyanamido Derivatives of Pyrimidine.
Inventor: BOEHM FREDERICK
Filed: 1904-08-03
Granted: 1905-08-03
Abstract: 16,996. Boehm, F., [Merck, E.]. Aug. 3. Oxycyanamidopyrimidines are produced by the interaction of one molecular proportion of dicyandiamide with one molecular proportion of such esters as cyanacetic, malonic, and acetoacetic esters, or their substitution products, such as diethylcyanacetic, monomethylacetoacetic, or monomethyl malonic esters, preferably in the presence of two molecular proportions of sodium ethylate. For example, a solution of suitable proportions of metallic sodium, ethylcyanacetate and dicyandiamide in absolute alcohol is heated to boiling for three hours under a reflux condenser. The resultant crystals of sodium salt are filtered off and, after evaporation of the remaining solution to dryness, are added to the residue and the whole dissolved in water and acidified with acetic acid to precipitate, in colourless crystals, the 2-cyanamido-4-amido-6-oxypyrimidine required. Similarly, colourless crystals of 2-cyanamido-4- methyl and 2-cyanamido-4 : 6-oxypyrimidines are respectively obtained when ethylacetoacetate and dietbylmalonate are the esters used. Barbitaric acids may be obtained by replacing the cyanamido group of these bodies by oxygen.

Title: Pneumatic Dispatch Tube Apparatus.
Inventor: SKIRROW JOHN FOSTER
Filed: 1904-12-29
Granted: 1905-02-23
Abstract: 28,790. Skirrow, J. F. Dec. 29. Pneumatic despatch apparatus.-A despatch tube 1, Figs. 1, 2 and 4, fits in vertical cylindrical chambers 4 in lower and upper terminal heads 2, 3, similar in every respect except that the upper head is furnished with a guiding-hood 38. Normally, the gates 6, fitted with leather strips 7 to seal the mouths of the cylinders 4, are open. A carrier being inserted in the cylinder, from below say, the corresponding gate 2 is closed, when a projection 18 thereon opens the spring- pressed valve 15 so that air can be introduced by means of the fan 31, tube 32, and holes 5 into the lower cylinder to propel the carrier. Another projection 13 on the gate brings two plates 10 in contact, thus closing an electric circuit, so that a current passes from the main lead P through wires 11<c>, contacts 28, 27, wire 11<b>, solenoid 26, and a wire 11<a> to a binding-post on an insulated strip on the lower head 2 ; the current then passes through plates 10 and a magnet 9 to another binding-post, through the wire 12<a> to the upper terminal head, and through a disc switch 22, 23, &c., Fig. 6, on the spring trigger 20 in this upper head to another binding-post 25, Fig. 2, and a wire 25<a>, to the other main lead N. The magnet in the lower head being thus energized, the armature 8 on the gate 6 is attracted and the gate is held in its closed position. When the solenoid 26 is energized, the armature 29, 30 is raised, breaking the contacts 27<a>, 28<a>, and preventing any possibility of a current through the magnet in the upper head while that in the lower head is energized. The armature contacts 29, 30 when raised come into contact with contactplates 29<a>, 30<a>, a current then passing from the lead P, through the wire 30<b>, and the field coil of the motor M to the lead N, a current also passing by means of the wire 29<b> through the armature circuit. The motor M which drives the air pump or fan 31 is thus started, and the carrier is propelled through the tube 1 and is expelled at the top, the gate 6 being open. The carrier however just before being delivered comes in contact with and turns the trigger 20 in passing, breaking the circuit, stopping the motor, demagnetizing the magnet, closing the air-inlet valve, and allowing the gate 6 in the lower head to open. The carrier may be passed from the head 3 to the head 2 in a similar manner, the contacts 27, 28 being broken and a current in the magnet of the lower head being prevented as described above. A pushbutton 33, Fig. 4, is used on each head to bring together two contact-plates 34, 35 to shunt and demagnetize the magnet 9, if the gate 6 becomes accidentally closed when no carrier is present. The trigger 20 is placed in a box and the magnet, contact-plates, circuit-breakers, &c. are protected by a casing.
