Granted: 1905-07-13
Abstract: 16,028. Johnson, J. Y., [Moya, J. de]. July 19. Purifying materials for; Bessemer processes; basic processes; open-hearth processes.-The recarburizing operation in the manufacture of Thomas, Bessemer, and Siemens-Martin steel is modified. As a preparatory operation, a mixture of one part each of potassium nitrate and chloride and two parts of sodium chloride is added to the metal before being run into the casting-ladle, in the proportion of two kilograms per ton. The mixture is thus rendered more suitable for the re-carburizing operation, for which carbon may be used, but preferably anthracite. A special anthracite called " carmoya " is preferably used because its ash contains from 2 to 6 per cent. of manganese, which largely desulphurizes the metal. The proper quantities of anthracite are placed in canvas, wood, or metal bags and thrown into the ladle at about equal intervals of time, beginning when it is about one-third full, and ending just before filling.

Abstract: 16,140. Arnold, J. O., Ibbotson, W. F., and Green, R. July 21. Testing metals.-A reciprocating action testing- machine for bars of steel or other metal is shown in section. The bar D under test is held by dies. C and a screw E, or by a vice, and is bent to and fro by a projecting arm G which can be coupled by a spring pin to a reciprocating slide H. This slide has a crosshead carrying a slide block N mounted on a shaft L driven from a motor. The slide R strikes a push-pin P of a counter at each return stroke, the counter being thrown out of action when the bar D breaks, and thus recording the number of reciprocations. This is effected by a rod linked through springs to a spring-pressed arm Q, of which the free end is attached as shown to the test bar. When the bar breaks, the arm Q rises and disengages the counter. The arm G is not coupled to the slide H until a high speed has been attained by the latter, a handle K being provided for raising the pin I.

Granted: 1905-08-10
Abstract: 21,303. Froggatt, B., Cook, W., and Bayley, T. Oct. 4. Brakes on trucks are kept applied by means of a catch D, Fig. 1, engaging an arm A<3> on a sleeve A', Fig. 3, which is mounted loose on the shaft C operated by the brake levers G. The sleeve A<1> is formed with a tumbler lever A and has a lostmotion connection with the shaft C, which is provided by a clutch A' as described in Specification No. 15,578, A.D. 1902. The catch D consists of a metal sheath with projecting ends between which is placed a block D', Fig. 1, which holds the device D against the member E. The brake lever is formed with an arm G<1>, which engages a projection D<5> on the catch D. The parts are so arranged that, on depressing the brake lever G to apply the brakes, the arm G<1> releases the catch and allows it to fall against the arm A<3>. On further movement of the brake lever, the catch D falls behind the arm A<3> and holds the brakes on. The catch is raised to release the brakes by the arm G<1>, which, pressing on the underside of the projection D<5>, raises the catch, any rotary motion of the catch being prevented by a stud E', Fig. 9, on the arm E, which engages with a straight edge D<4> of the catch. In place of the projecting arm G<1>, a rod H, Fig. 9, may be pivoted to the catch at D' and connected with the lever G by a pin and slot G<2>. The catch may be applied as shown in Fig. 10, the arm A<3> being connected by a link M to the brake lever G. The link M is provided with a slot M' to provide a lost-motion connection, and an incline M<2> to engage with and raise the catch D. The brake levers G, Fig. 1, on opposite sides of the truck are connected by a transverse shaft J<1> and a link J' to provide a right-handed lever on each side. The brake rods B are adjusted by means of H-shaped pieces K, Figs. 5 and 6, placed in a slot B<3> formed in the rod B, the pieces being moved to the one side or the other of the pin B' connecting the rod B to the tumbler A. The Provisional Specification states that the brake levers are held in the raised position by a catch such as is described in Specification No. 16,490, A.D. 1901, which, instead of being pivoted to the frame, may slide in horizontal guideways and be held in its intermediate position by springs.

Title: Improvements in Power Transmission Devices.
Inventor: STEWART JOHN KERWIN
Filed: 1905-04-18
Granted: 1905-11-30
Abstract: 8301. Stewart, J. K. April 18. Gearing, driving. -Relates to devices for transmitting power from a rotating shaft through toothed gearing and clutches, particularly adapted for driving a plurality of secondary shafts actuating handdirected tools, the action of which may be governed independently. The driving-shaft 1, Fig. 1, carries a gear wheel 3, engaging a pinion 8 loose of the secondary shaft 5, and kept in position by a forked plate 13. Upon the pinion and also upon a sleeve 6 secured to the shaft are bevelled teeth 9 which form a driving-clutch. The pointed end 5<b> of the shaft 5 bears against an adjustable screw 11 on a lever 10, which moves the shaft and thus the clutch out of gear. The end of the lever engages between spring projections 14<a> on a fixed piece 14, which hold the lever in either of its two positions. When the resistance of the work to the tool becomes too great, the pressure of the bevelled teeth 9 together forces the shaft 5 endwise and presses the lever 10 past the projections 14<a>, thus throwing and keeping the tool out of action.

Title: Improvements in Safety Gear for Mine Skips, Cages and the like.
Inventor: WELDON EDWIN GEORGE
Filed: 1905-08-09
Granted: 1905-12-30
Abstract: 16,237. Weldon, E. G. Aug. 9. Safety suspending or retaining apparatus; shocks, preventing; buffers.- Relates to safety gear for mine cages and the like. The frame in which the cage A is carried is extended upwards a suitable distance and connected by top bars B. Between these bars and the top of the cage is a number of vertically-disposed guide-rods C on which slide bars D, guided by channels b<7> on the frame extension A' and connected by the suspending- hook E. On each of the rods s C, between the bars B, D, are strong buffer springs d<3> and helical springs d<2>, the latter extending nearly to the cage roof and carrying the crossbars D with them, when the cage is not suspended. Arranged between and supported by bearings f in the sliding bars D are two cylinders F with strong coiled springs f<8> located therein. The cylinders are filled with fluid which can pass from one side to the other of the piston f<3> either by channels f<4> or by an external pipe e<6> provided with stop-cocks. Under normal conditions, the bars D are drawn up against the buffer springs d<3>, the helical springs d<2> being compressed within these latter. In the event of a fracture in the winding-rope, the bars D are depressed by the springs d<2>, and the piston-rods f<5> are forced outwards and directed by guides G to rest upon transverse teeth or projections h on the guide rails or runners H. This causes the springs d<2> to be again compressed, and the energy of the cage is partially absorbed by the buffer springs d<3>. After the buffer springs have been compressed, the cylinders F are forced over the piston f<3>. This causes the fluid in the cylinders to be forced through the, grooves f<4> and the springs f are compressed, thus taking up the energy of the load, the cage being brought to rest. When the cage is again suspended, the stop-cocks in the tube e<6> are opened to allow the fluid to pass back to the upper side of the piston.
