Title: Improvements in Apparatus for Use in Casting Ingots.
Inventor: LUSTIG ADOLPHUS JOHN
Filed: 1901-03-26
Granted: 1901-10-19
Abstract: 6323. Lustig, A. J., Kahn, L., and Lehman, I. March 26. Ingots.-A mould 18, for use in casting steel ingots, is placed upon a plate 17, formed with a shouldered recess in which is fitted a central metal plate 21. The plate 17 is supported by a block 6, having inclined sides resting upon ribs 4, extending from the inner surfaces of a box-like support 2, 3. The plate 17 may also be formed with an open channel 24, for receiving carbonaceous matter ; this channel is connected by a duct or ducts 25 with the spaces between the block 6 and its support 2, 3. The channel is closed by cover - plates 28, having bevelled edges 29, which form, with the lower part of the mould, an annular chamber round the joint between the mould and plate 17. The hydrogen, or gaseous hydrocarbon, is admitted into the spaces between the block 6 and its support, by means of pipes 9 and channels 11, 12, and 13 formed in the block. When the molten steel has been poured into the mould, these gases circulate through channels 16, formed in the upper part of the block 6, and diffuse through the heated plate 21 into the mould ; some of the gas also passes through the channel 24, and flows beneath the edges of the plates 28 into the annular chamber below the bevelled edges 29. The spaces between the block 6 and its support may be filled with pumicestone or other similar material. The mould 18, which is of any known kind, is provided with steel plates 31, secured by means of slots and bolts 32 so as to allow for expansion and contraction of the mould. When casting Bessemer steel, and it becomes necessary to cool the mould by means of water, the block 6 is dispensed with, and the mould rests upon a plate having a shouldered aperture within which is fitted a plate or block similarly recessed and receiving another plate or block. The lower portion of these two blocks may rest upon the interior of a box-like support, the bottom of which is formed with inclined channels whence the water flows to a discharge pipe. Hydrogen or gaseous hydrocarbon is introduced by means of a pipe into spaces in the mould-supporting plate. The joints between the parts of both forms of mould are preferably filled with cardboard, as shown at 48, Fig. 1. In an arrangement comprising several moulds intended to be filled from a central runner, the moulds are mounted upon a circular or other base - plate formed with radially-disposed channels for the reception of pipes for conducting the molten steel from the central runner to the lower parts of the moulds. The delivery ends of these pipes may have more than one outlet, so that several streams of molten steel can be admitted to each mould. Beneath the radially-disposed channels are chambers filled with loose material, through which hydrogen or gaseous hydrocarbon passes from supply pipes.

Title: Improvements in or connected with Spring Balances or Scales
Inventor: NAHMER WILHELM VON DER
Filed: 1901-04-24
Granted: 1901-07-06
Abstract: 8460. Nahmer, W. von der. April 24. Spring balances.-A balance of the kind fitted with two sets of springs for light and heavy weights, respectively, is fitted with an adjusting-device as shown in the Figures. The scale rod b has a cross-bar c at its lower end by which it is suspended from a bar l through two sets of springs d, e. The weaker springs d are connected to the stronger springs e by links f, into which project stops g formed on vertical bars h, which are also supported from the bar l. The bar l is pivoted to the casing at its ends, and has a downwardly-extending arm m controlled by an adjusting-screw n, by altering which the springs and scale-pan can be raised or lowered so as to adjust the pointer o to the zero by means of the rack-and-pinion gearing q. By suspending both the springs and stops from the same adjustable bar l, any error in the zero indication of the pointer is corrected, and the subdivisions of the dial will still correspond to the extension of the springs. Instead of the load being taken off the light springs, when they are fully extended, by the stops as in the balance shown, the springs may be arranged so that the light springs are not relieved of their load.

Title: An Improved Method and Apparatus for the Production of Pulleys of Wrought Iron or other Suitable Material.
Inventor: BERTHOLD RICHARD
Filed: 1901-06-12
Granted: 1901-08-17
Abstract: 12,013. Berthold, R., and Dietrich, E. June 12. Stamping ; bending.- Relates to a method and apparatus for making pulleys of wrought iron or other suitable material by stamping and bending. A sheet blank is stamped to form ribbed arms 1, Fig. 2, and a half boss 2. The boss is then ribbed, portions 4, Fig. 4, set back, and holes 5 cut in the ends, the distance d being less than the desired diameter of the pulley by twice the thickness of the rim. The ends 6 are then flattened, and the blank trimmed, after which the ends are bent back as shown in Fig. 7. A half rim is formed from a blank, Fig. 13, with end tongues 12, and having strengthening-flanges 11 partially formed, the bending of the rim and flanges being completed by rolls. The tongues 12 are then bent in, and the parts assembled as shown in Fig. 9, the half rims being riveted to the arms, and the two halves of the pulley being connected by bolts 9. The same method may be applied to constructing pulleys in four parts. Fig. 17 shows a pair of rolls for bending and flanging the half rims. The upper roll c is plain, and works in a grooved roll e, the groove being shaped to suit the rim. The curvature is determined by a table m, angularly adjustable on a quadrant q and having guide-flanges n to feed the blank to the rolls. A table o at the rear has a knife end bearing on the lower roll, and is carried by trunnions t sliding in guides i and adjusted by screws r. The guides are pivoted so that the knife end may be kept on the roll by a spring u. The adjustment of the tables determines the curvature of the rim. The bending of the ends of the arms and rims may be effected in screw presses with dies and mandrels shaped to suit the angles of the bend. Fig. 23 shows a press bending an end of the half rim over the arm, v being the supporting-mandrel and y the moving die.
