Title: Improvements in and connected with Pneumatic Power Hammers.
Inventor: PLAYER WILLIAM DREDGE
Filed: 1897-06-03
Granted: 1898-05-07
Abstract: 13,670. Player, W. D. June 3. Hammers, power.-Pneumatic power hammers with a reciprocating air cylinder A are provided with a series of air ports d<1>, d<2>, &c., communicating with the interior of the cylinder, and a valve E with a series of air openings e<1>, e<2>, &c., spaced so that only one opsning e<1>, e<2>, &c. can come opposite one port d', d<2>, &c. at a time. The valve E can be moved by a bell-crank lever F moving in a slotted bar C, to which vertical motion can be imparted by treadle mechanism. Any opening e<1> &c. can be brought opposite any port d' &c. in the cylinder A to vary the amount of air trapped below the piston B carrying the tup and consequently the force of the blow. The valve may be arranged to slide horizontally instead of vertically, or may be arranged as a cylindrical sliding valve or a disc rotated about a centre.

Title: Improvements in Controlling Mechanism of Revolving Shuttle Boxes of Looms for Weaving.
Inventor: SMITH EBER
Filed: 1898-02-05
Granted: 1899-01-21
Abstract: 2922. Smith, E. Feb. 5. Loom change-box motions.-In rotary shuttle-box motions in which the pattern surface operates in a lateral direction as well as lengthwise, the pattern cylinder is mounted in a suitable frame b, and in each lag or card c of the cylinder any desired number of holes are formed for the reception of long and short pegs d. A screw shaft g, mounted on rocking levers f, f and having at its end a starwheel m, is placed above and parallel to the cylinder. Intermittent rotary motion is given to the screw g by arranging that one or other of the ratchets n, n<1> shall be in contact with the wheel m as the shaft g is raised by the levers f, f<1>, and the nut or screwed bracket h, carried on the screw shaft and prevented from rotating, is thus carried intermittently along the screw g, the direction of motion depending on which of the two ratchets n, n<1> engages the wheel m. At each of the intermittent motions the bracket h is moved from one peg to the next, the height of the peg determining the position of the lever f, which controls the motion of the shuttle boxes, as described in Specification No. 21,424, A.D. 1891. The ratchets n, n' are coupled together by a spring q, and a cam-plate placed between them determines which of the ratchets shall engage the wheel m. The cam-plate is mounted on the shaft of the pattern cylinder, and when the latter moves one lag forward the effective position of the ratchets n, n<1> is changed. The ratchet r<1> engages with the wheel t whenever one or other of the fingers n, n<1> of a lever pivoted to the bracket h is pressed on one of the pegs v, v<1> at the end of the pattern cylinder and causes the wheel t to press on the other end of the crank rod t<1> and move the catch t<11> sufficiently on the lever r<11> to allow the lever r<1> to descend and come into contact with the wheel t, so that, on the next upward movement of the lever r<11>, the cylinder will be rotated through the space of a lag and thus reversal of the screw g and advancement of the lags take place in unison, while should reversal of the screw g be required midway an extra peg is arranged to effect the desired result. The camplate turning with the pattern cylinder, both of the ratchets n, n<1> are thrown out of contact with their wheel m at the same time, and the screw g is left unmoved and brings its bracket h into contact with the pattern surface in the same vertical plane twice in succession.

Title: Improvements in Boiler Feed and other Pumps.
Inventor: HALL JOHN PERCY
Filed: 1898-06-20
Granted: 1899-05-20
Abstract: 13,681. Hall, J. P. June 20. Starting, f a c i l itating.-Relates to feed and other pumps which are started and stopped by the movements of a float in the supply tank, and consists of means for facilitating the use of steam expansively in such pumps. The opposite ends of one or several of the water cylinders of the pump are connected by a passage F, so t h a t a starting there is practically no load on the pistons of these cylinders, and the steam cylinder which is in a position to receive steam is able to start the pump alone. The passage F may be controlled by a valve G connected with the float in the supply tank. A small hole in the pump piston may be used instead of the passage F. The invention is applicable both to simple and multiple expansion engines.
Patent GB-189816475-A (GB)
Title: Manufacture of Acridine Derivatives.
Filed: 1898-07-28
Granted: 1899-07-15
Abstract: 16,475. Abel, C. D., [Actiengesellschaft fiir Anilin Fabrikation]. July 28. Acridine derivatives.-Acridine derivatives of the naphthacridine series are prepared by the action of #-naphthol upon an aldehyde, such as formaldehyde or benzaldehyde, and p-toluidine, or upon condensation products obtained from p-toluidine and an aldehyde, or by the action of p-toluidine upon the condensation product obtained from #-naphthol and an aldehyde. An intermediate leuco compound is first formed which is partly oxidized during the process, and its complete conversion into the acridine derivative is effected by the action of air or other oxidizing - agent. Examples are given in which (1) tolunaphthacridine of the formula which melts at 158‹ C., is produced by heating trioxymethylene, and a melted mixture of #-naphthol and p-toluidine to 300‹ C., and purifying the product by means of its nitrate ; (2) phenyltolunaphthacridine of the formula which melts at 213‹ C., is produced by heating the oily condensation product of p-toluidine and benzaldehyde with #-naphthol to 200‹ C, and purifying the product by means of its nitrate ; and (3) p-nitrophenyltolunaphthacridine, which is insoluble in most solvents, is produced by heating the condensation product of p-nitrobenzaldehyde and p-toluidine with #-naphthol to 190‹-195‹ C., and removing soluble bodies from the melt by means of alcohol.
