Inventor: HEENAN HAMMERSLEY
Filed: 1903-10-31
Granted: 1904-10-27
Abstract: 23,616. Heenan, H. Oct. 31. Gas-producers.-An apparatus for making crude gas from coal and other material consists essentially of an upper chamber A connected with a lower chamber B by a contracted passage C. The coal is fed into the upper chamber through a hopper E, and the air for primary combustion is supplied through a tuyere F. The tuyÞre is partly filled with water, and the air is blown into the producer by a steam jet G or otherwise, carrying with it the steam or vapour rising from the water. The gases produced in the upper chamber pass by a duct to a tuyÞre F<1>, also supplied with a steam jet or injector G<1>, through which the gases, together with air and steam, are forced into the lower chamber, and pass up through the incandescent material which has fallen from the upper chamber. The gases finally pass through a flue or flues round the top of the lower chamber, and then through main flues D, D' to a receiver. The sides of the upper chamber are inclined to direct the fuel towards the centre of the lower chamber, which is provided with a bridge L to support the incandescent mass. The cinders fall into a trough K, from which they may be removed without admitting air to the lower chamber.

Title: Improvements in and relating to Electric Motors.
Filed: 1904-03-10
Granted: 1905-02-16
Abstract: 5926. Mavor & Coulson, and Mavor, H. A. March 10. Motors, alternating-current; motors, controlling; motors, gearing for.-In order that the speed of rotation of induction motors may be reduced without altering the number of poles, the primary and secondary are mounted so that they are both capable of rotation, and provided with means by which the two elements may be geared together. In Fig. 4, the two elements are shown connected by an open band b, and by a crossed band f with a common shaft d, the speed of which is equal to the speed of each of the elements, which is half the synchronous speed of the motor. The velocity ratio, however, may have any value, depending upon the diameters of the pulleys. In a modification, Fig. 5, the two elements are connected together by toothed gearing. For the purpose of starting the motor, a friction clutch o may be used. The primary is disconnected from the secondary until it has attained its maximum velocity, when its speed is reduced and that of the secondary started and increased by the gradual application of the friction clutch. If it be desired to reverse the motion of the driven shaft, the mechanism shown in Fig. 6 may be employed. The two elements of the motor are each connected by a crossed and an open band with the shaft d, the rotation of which is in one direction when the bands b, f ride on the pulleys c, e and in the opposite direction when the bands b<1>, f<1> ride on the pulleys c<1>, e<1>, the idle pulleys p, q in both cases riding loose on the shaft d.

Title: Improvements in Sand Moulding Machines
Inventor: HUDSON FRANK WESLEY
Filed: 1904-10-11
Granted: 1904-11-17
Abstract: 21,829. Hudson, F. W. Oct. 11. Moulding.-In moulding-machines, the mould is lowered away from the pattern at the same time as a power-rapping device is in action, and the patterns are mounted so as to be easily changed. A pattern 19, Fig. 9, is embedded in plaster of Paris or the like in a tray 17 bolted to cross-bars connected by studs and springs 17<d> to a trunnioned frame 16, Figs. 2 and 9. The underside of the tray carries the rapping-device 38. A hand-lever, with a spring catch 26, mounted on one of the trunnions provides means for reversing the frame 16, and a pair of stops 27 engage the catch 26 and hold the frame secure in either position. A number of bolts 21 with eccentric heads 22 secure the flask to the frame 16 ; the bolts are simultaneously turned to release the flask by linkage from a handle 24. In operation, a flask is secured above the frame 16, and is rammed. The frame is reversed to the position shown in Fig. 2, the rapping-device is started, and a table 37 is raised to receive the mould, which is separated from the pattern and lowered on to rails 35. Should the mould and pattern stick a little, the springs 17<d> allow the latter to descend a little way to facilitate the action of the rapping-device. The table 37 has a yielding spring connection to a plate 32 which is raised and lowered by cranks and rods 31 operated from a lever 28. Tubular guides 33 steady the motion, and a dash-pot prevents too rapid withdrawal and possible fracture of the mould.

Title: Improvements in Grinding Machines.
Inventor: THOMPSON DAVILLA STURTEVANT
Filed: 1904-11-03
Granted: 1905-06-01
Abstract: 23,799. Thompson, D. S. Nov. 3. Lenses.-A machine specially applicable for grinding spherical, cylindrical, toric, and other lenses is constructed with work-carriers F, Fig. 4, preferably two, mounted on arms G, which are pivoted to a vertical spindle J<3> mounted in a yoke K, The ends of the yoke are engaged by crankdiscs L', L<3>, Fig. 3, which are driven by skew gearing from a shaft O<2> so as to impart motion to the yoke bodily, and consequently to the workcarriers. The crank discs and shaft O<2> are mounted in a frame N, which is caused to reciprocate on rods N' by a link pivoted at one end to the machine table A' and at the other end to an adjustable crank-pin on a disc P<3> secured to the upper end of a shaft P<2>, this shaft being mounted in the frame N and driven by worm gearing from the shaft 0<2>. The shaft 0<2> is driven by a belt passing over a broad pulley O<3>, and the workcarriers thus receive a compound motion, the gearing being chosen so that a considerable interval elapses between successive actions of the work. The work is moved over a disc D secured to a shaft H carrying a centrifugal pump C for delivering the grinding-material on to the disc from a surrounding pan B. The shaft H and disc are rotated when grinding spherical lenses, but the disc is stationary when grinding cylindrical, toric, &c. lenses. Springs G<1> act on the arms G to press the work against the disc, and either arm may be raised or locked in its raised position by a pivoted hand-lever G<3>, which operates a pivoted catch to engage a notch in the eye of the spindle J<3>. An arm Q projecting from the spindle is normally looked to the yoke by a screw Q<1>, but may be released when it is desired to turn the spindle so as to move the work from the disc laterally. In grinding a pair of cylindrical lenses, the lenses are mounted on blocks engaged by the carriers F and moved singly over the grinding-disc D, but in grinding spherical lenses, the lens is secured to a disc which is fixed to both of the carriers F.
