Granted: 1898-08-20
Abstract: 21,553. Green, A. G., and Wahl, A. R. Sept. 20. Dyes, artificial.-Relates to the production of dyes from the dinitrodiphenylethane disulphonic acid of the formula :- [4 : 2 : 1]NO,(SO,H)C.H3CHsCHsCGH3(S03H) NO2[1 : 2 : 4] which is described in Specification No. 5351, A.D. 1897. (1) Dyes which yield yellow to orange shades upon unmordanted cotton are produced by limited reduction of the said dinitrodisulphonic acid, preferably in alkaline solution, with zinc dust, ferrous hydrate, sodium stannite, lead, glucose, glycerin, benzaldehyde, &c. (2) Yellow, orange, and brown dyes for unmordanted cotton are produced by condensing the aforesaid dinitrodisulphonic acid with aromatic diamines, phenols, amidophenols, nitramines, or their sulphonic or carboxylic acids. Examples are given in which aniline, m-toluylenediamine, a-naphthol, and dehydrothiotoluidine sulphonic acid, respectively, are used. (3) The dyes described in the preceding section are converted into dyes of redder shade by limited reduction by the method described in section (1). (4) The dyes produced by the preceding. processes (2) and (3), which contain a free amido group, are diazotized in substance or upon the fibre, and are converted into dyes of darker shade by combination of the diazo compounds with m-phenylenediamine, m-toluylenediamine, phenol, resorcin, salicylic acid, a- or #- naphthol or a sulphonic acid thereof, a naphthylamine sulphonic acid, a 1 : 8-amidonaphthol or 1 : 8-dioxynaphthalene sulphonic acid, or the like. The foregoing diazo compounds may also be used as components in the production of polyazo dyes by the known processes.

Title: An Improved Adaptable Mechanical Stage for Microscopes.
Inventor: ALLEN ALFRED BULT
Filed: 1898-02-07
Granted: 1898-12-10
Abstract: 3082. Allen, A. B. Feb. 7. Microscopes.-Relates to a mechanical stage. The object-slip B rests against a guide D secured to a dovetailed slide E which is traversed by a rack and pinion g in the guide F by turning the milled head G. Transverse movement is given by a friction gripping-piece H on a rack h sliding in an arm C. This arm is pivoted at c so that it can be turned into or out of action, and the transverse movement is effected by turning a milled head I on the spindle of a pin gearing with the rack. The position of the arm C, whether in or out of action, is determined by the pressure of a spring c<1> on a wedge-shaped heel. In a modified form, the firstdescribed motion may be obtained in an ordinary manner, and the arm C may be formed as a toggle. In this case, the transverse feed is given by a friction roller at the end of the toggle geared by a silk cord with the spindle of the milled head.

Granted: 1900-05-05
Abstract: 9521. Boult, A. J., [Dolder, J.]. May 5. Yarns and threads, mercerizing &c.-For treating hanks with mercerizing or other liquids, they are placed over pairs of rollers a<1>, b<1>, . . . a<6>, b<6> carried by an intermittently-rotating frame, the rollers being provided with a brake band, so that, when the frame is blocked, the rollers are rotated on their axles, and, when the frame is free, the rollers are not rotated on their axles but are carried forwards by the rotation of the frame. One roller of each pair is fixed in the frame, while the second one is carried by bell-crank levers pivoted in the frame, the free ends of the levers engaging with adjustable cam surfaces so that the tension on the hanks is increased and decreased as desired during the revolution of the frame. The fixed rollers are preferably octagonal in shape, being covered with india-rubber, having longitudinal ribs. In the first position, the hanks are applied to or removed from the rollers, and in succession the hanks are treated with mercerizing-liquid supplied from an overhead tank, subjected to pressing, rinsing, and draining operations, and finally brought into position for being removed' by hand. The hanks may be caused to remain in the apparatus during two or more revolutions of the frame. X is a tank for receiving waste mercerizing-liquid, and Y is a trough for receiving waste washing- water. In the positions a', b<5> and a<6>, b<6>, the hanks are above a waste tray and beneath removable covers E, which are closed when the frame is at rest and the hanks on the rollers a<5>, b<5> are being washed, while, just before the frame is rotated. the supply of wash water is automatically shut off and the covers E are simultaneously opened, the water being automatically turned on and the covers closed when the frame is stopped and the rollers commence to rotate on their axles.

Title: A Clutch, with or without a Locking Device, for Cycles and other Machines.
Inventor: JONES WILLIAM
Filed: 1900-01-16
Granted: 1900-12-01
Abstract: 918. Jones, W. Jan. 16. Clutches.-Relates to free-wheel clutches for cycles &c. so arranged that the chain ring is held clear of the rotating parts when the wheel is overrunning, and sometimes fitted with arrangements to allow back-pedalling. Figs. 1 and 2 show one form. The chain ring F, formed with fixed and adjustable inclines G, is so mounted as to turn freely on corresponding collars A, C, fixed to the hub 0 and a stationary part of the frame, such as the fork D, respectively. A clutch piece E is formed with inclined toothed or plain surfaces e<3>, e' corresponding to inclined surfaces a<2>, c<1> on the pieces A and C. This clutch piece surrounds the hub locking-nut B, and its outer surface is formed with recesses to engage threads f<2> on the interior of the chain ring F. During forward driving, the threads f move the clutch piece E inwards, and cause its surface e<3> to bind on the surface a<2>, while during back-pedalling, the clutch piece engages the collar C and gives fixed pedals. In order to lock the clutch piece in engagement with the hub collar, a divided ring is mounted on the chain ring, and is connected to it by pawls. This ring is also connected by a spring to a brake drum which is formed with projections engaging the pawls. The ring is formed with lugs passing through slots on the chain ring, so as to engage reverse threads on the clutch piece. By first applying and then releasing a brake acting on the drum, the pawls are raised and then dropped, so as to lock the clutch piece in engagement with the hub and allow backpedalling. In a modification, a screw thread cut on the outside of the chain ring is fitted with a nut and collar, with a locking-piece arranged in conjunction with a brake drum to lock the clutch piece similarly. The inclines on the clutch piece E and on the collars A, C may be reversed.
