MERCERIZING APPARATUS.

Paul Edlich, of Triebes, Germany. Patent No. 783,569, dated February 28, 1905.

This invention relates to an apparatus for mercerizing cotton fabric wherein the fabric is passed uninterruptedly through the initial tension-machine, then through the proper mercerizing device, and then through the final tension-machine. While with the known machines relating to this art the fabric as soon as it leaves the initial tension-machine has to be transported by hand to the mercerizing device proper and after going through the same has to be transported by hand to the final tension-machine, the present invention provides for a continuous treatment of the fabric in these several apparatus, which have been combined in one mechanical combination.

DYEING APPARATUS.

Daniel F. Waters, of Philadelphia, Pennsylvania. Patent No. 785,283, dated March 21, 1905.

This invention relates particularly to certain improvements in the frame upon which the yarn is suspended over an open rectangular kettle and means to move the yarn-sticks to progress the yarn hung thereon.

These improvements comprise means to intermittently rotate the yarn-sticks, including ratchet-wheels on the respective sticks, pawls engaged with said wheels, a bar common to said pawls, and means arranged to reciprocate said bar in definite relation to the movement of a liquor-circulating wheel.

It also includes yarn-sticks of polygonal cross-section having recesses between their angles, permitting access of the liquor between the sticks and the yarn thereon, and an improved liquorcirculating wheel mounted upon a horizontal axis and having a plurality of blades extending parallel with said axis.

WARP-DYEING MACHINE.

Theodore E. Davis, of Winston Salem, North Carolina. Patent No. 785,597, dated March 21, 1905.

The object of the invention is to provide a machine for dyeing warp which is so constructed as to permit of dyeing a large amount of warp at one time, to reduce the tension on the warp to a minimum, to prevent tension on the warp during the dyeing operation, to obtain the necessary oxidation of the warp during the dyeing operation, to keep the dye-bath at a regular temperature throughout the run, and to produce even shades in the finished product, thereby overcoming the great difficulty in matching one warp with another.

The invention further aims to construct a machine for dyeing warp various colors, as sulphur-blacks, cutch-brown, anilin-blues, &c., and which shall be simple in construction, strong, durable, and efficient in its use.

DYEING-MACHINE.

APPARATUS FOR PRINTING WARPS ON PRINTINGDRUMS.

Franz Schmidt, of Oberschöneweide, Germany. Patent No. 789,068, dated May 2, 1905.

The present invention relates to an apparatus for printing warps on printing-drums, wherein the adjustment of the printingdrum is effected in such a manner that its movement is dependent upon the movement of the adjusting device for the design. Hence there exists such a relationship between the adjusting device, con

sisting, for instance, of an indicating device and a pattern-carrier, and the printing-drum that owing to the relative movement occurring between the indicator and pattern-carrier a movement and adjustment of the printing-drum is effected. The inducement for the movement of the printing-drum can at the same time be given by the pattern-carrier or by the indicating device, or by both simultaneously. In order to obtain a sharp coincidence between the movement of the adjusting device and the movement of the printing-drum and to admit of the use of transmitting mechanism of the simplest kind, the pattern is directly connected to the printing-drum, so that on adjusting the design on the indicating apparatus the adjusting of the printing-drum is automatically effected. The driving mechanism will be all the more simple if a uniform movement be had between the pattern-carrier and the printing-drum—i.e., by also forming the pattern-carrier as a drum. It is, furthermore, important that there be mounted between the pattern-carrier and the printing or warp drum interchangeable or adjustable driving-mechanism transmissions.

DOUBLE PRINTING-DRUM FOR WARPS.

Franz Schmidt, of Oberschöneweide, Germany. Patent No. 789,069, dated May 2, 1905.

The subject-matter of the present invention is a double printingdrum for warps, consisting of two drums of different circumference which can simultaneously be printed with the same pattern, as both drums receive the same angular rotation. This uniform angular rotation is obtained by the intercalation of gearing. It is furthermore essential that the two warp-drums of different circumference be driven together with a drum containing the design or pattern, the driving thereof being effected in that drivingcrowns are provided on the circumference of the drums. By means of this arrangement a pattern from the same design is simultaneously printed upon different lengths of warp and when working with one upon the other the same number of printed strips is printed off and, viz., corresponding to the circumfer

ences, upon the larger drum printed strips of greater breadth and on the smaller drum printed strips of smaller width, the advantage being obtained that the patterns upon both drums are entirely the same under all circumstances. The new apparatus can, for instance, be used for simultaneously producing the warps for the seats and pockets used in covering sofas. These were formerly made separately on different machines, the drawback in printing them in this way being that owing to mistakes confusion occurred between the patterns of the seat-warps and of the pocket-warps. This drawback is prevented by the compulsory connection of the two drums of different circumference to each other. Furthermore, the advantage is obtained that the two patterns of different size can be made with a great saving of time and labor. Whereas formerly two persons were required for serving two machines, one hand only is required for the new apparatus. By the use of the pattern-drum common to both drums the advantage is furthermore obtained of rapid adjustment and a further economy of time and labor. As the design is already printed upon the pattern-drum or the like, all the operative has to do is to move this drum and no longer needs to read off figures from the design (pattern) and edge of the printing-drum prior to making the adjustment.

MACHINE FOR MERCERIZING, &c.

William Henry Crompton and William Horrocks, of Radcliffe, England. Patent No. 789,260, dated May 9, 1905.

This invention relates particularly to improvements in the type of machines for mercerizing, scouring, bleaching, dyeing, washing, and like treatment of yarn in hank form described in U. S. Patent No. 680,131, and in which the hank-reels are mounted in frames employed in a tank and are carried by the hanks and the latter thereby subjected to the whole weight of the said frames, which improvements may, however, also be used in connection with hankreels mounted in any other suitable manner. In the said type of machines it is necessary to lift the said hank-frames out of the tank for the purpose of draining the hanks previous to further
