Printing hanks of yarns or threads and warps with one or more colors. Dated May 26, 1868. This invention is carried out as follows:-In suitable framework the inventors place one, two, or more pairs of ordinary grooved printing rollers, one above the other, the rollers being supplied with colour rollers in colour boxes in the usual manner. On the shaft of the printing rollers there are bevel wheels, gearing into bevel wheels attached to boxes fixed to a shaft driven by worm or toothed gearing from the driving shaft of the machine, the said boxes being provided with screws for adjusting the wheels to enable the projecting ribs of the rollers to correspond with exactness. At the insides of the framework, beyond the ends of the rollers, they place two elevating or carrying screws, having square threads of any required pitch, and turned by bevel wheels from the driving shaft of the machine, and the hanks of yarns or threads are held on rods placed in the grooves of the screws, the rods having projecting ends fitted to work in two metal guides at the front of the screws. The screws are turned at a speed exactly corresponding with the surface speed of the printing rollers, and at the tops of the screws there are cams fixed, so that when the rods arrive at the tops of the screws they deliver the rods with the hanks on to two brackets fixed to the tops of the two metal guides. One printing roller of each pair, with its corresponding colour roller and colour box, is mounted on sliding pedestals adjusted with screws and springs, so that when the rods with the hanks pass between the rollers, the springs shall yield to allow them to pass, and afterwards expand, to give the required pressure for printing the colours.-Patent abandoned. 1728 A.

Dated May 26, 1868. wire is sealed, so as to be in metallic communication with the mercury of the thermometer. In the upper part of the bore of the thermometer stem is another similar wire, which may either be sealed in the said bore, or may be capable of sliding through a stuffing-box, or otherwise, in the said bore. The two wires described are respectively in communication with the positive and negative elements of a voltaic battery, and in the circuit of the said battery is an electro magnet. When the temperature of the hothouse or other room rises so high that the mercury in the bore of the thermometer ascends sufficiently in the said bore to come in contact with the wire in the said bore, an electrical communicatlon is thereby established, the voltaic circuit is completed, and the electro-magnet referred to is excited and becomes powerfully magnetic. When the temperature of the hothouse or room falls so far as to cause the mercury in the bore of the thermometer no longer to touch the wire in the bore, the electrical circuit is broken, and the electro-magnet referred to loses its magnetic power.

The copper wire received at the gutta-percha works is first tested for its quality and its conductivity; the standard being known, it is easy to determine whether the wire received is up to it; all copper above the standard is passed and prepared for forming the conductor, which consists of a strand of seven wires. In making this strand the centre wire is passed through a bath of what is generally known as Chatterton's compound According to the report of the engineers, (a mixture of tar and gutta-percha) before it would appear that the amount of work having the remaining six wires wound round accomplished up to the present date, is about it, the object of this compound being to 600 miles of deep sea cable.
