' T0 all whom it may concern,.-

Be it known that I, AUGUST FREDRIK LUN- DEBERG, mechanical engineer, a subject of the King of Sweden andNorway, and a resi- 5 dent of Observatoriegatan 16, Stockholm, in

the Kingdom of Sweden, have invented certain new and useful Improvements in Apparatus for Manufacturing Carpets or Mats in Through-Colored Patterns, of which the folxo lowing is a specification.

The extensive use gained by the well-known carpets composed of some cork composition and the like has made it desirable to produce such carpets in through-colored patterns,

I 5 since a carpet of this description does not suffer from the defect common to carpets with surface-colors only-viz., that the colors are soon worn E. This invention therefore relates to an apparatus by means of which the 2o said throughcoloring of the carpet can be accomplished in a simple manner, so as to produce aperfectly-clear pattern through the entire thickness of the carpet.

It consists of two printing-blocks between 2 5 which the carpet is placed and which blocks,

both the upper and the lower one, contain depressions or cells corresponding to the details of pattern and being exactly alike in both blocks, so as to be directly opposite one an# 3o other when the blocks are placedtogether,

of passages and pipes for introducing the coloring liquids into the cells of the lower block,

of other passages or pipes for introducing air or other suitable gas in the same cells for dry- 3 5 ing the carpet subsequent to thethrough-coloring, and of means for creating a vacuum in the upper block, as will be more fully de-V scribed below. In the drawings annexed the apparatus referred to is shown in Figure 1 in a transverse section, and'in Fig. 2 in a plan view. Fig. 8 is a plan view of'a corner of the lower colorblock, and Fig. 4 is an end elevation of a vacuum-pump. l

1 and 3 designate the two printing-blocks, and 2 the carpet placed between them. Both blocks have depressions or cells 4, corresponding to the pattern required. These depressions or cells are exactly alike in both blocks', o so that the edges of the cells in one block will be exactly opposite those in the other when the blocks are placed one on top of the other.

If thecarpet be placed between the blocks andthe latter be pressed forcibly together, there will consequently, owing to the penetration of the edges of the cells into the surface of the carpet, be produced closed chaml v bers 4 on both sides of the carpet, each of said chambers being well shut ol from the adjacent chambers close to the surface of the carpet in the same block as well as from all the chambers in the opposite block, excepting that directly opposite, which is only separated from the former by the carpet itself. This is of particular importance for, the purpose in question, inasmuch as when the depressions of one blockl are iilled with coloring liquid and a suction is produced in the depressions of the other block the coloring liquid in each depression will be drawn perpen- 7o dicularly through the carpet. The coloring liquids are, distributed, according to ther pattern desired, in the different depressions of the bottom block, (therefore called the colorblock bclow,) the depressions of which, called color-cells,7 are connected either in groups or rows with each other through pipes 5, passages 6 in the block proper, and apertures 7, the latter located in the bottom of the cells. The pipes 5 issue from the respective color reservoirs. In the pipes are inserted smaller pipes 8, provided with perforations 9 directlybelow the holes 7. The i pipes 8 communicate with the pipes 10,which may run together `into one single pipe. The object of these pipes 8 10 is to facilitate A the emptying of the cells and make possible the passage of the adhering coloring liquid into and through the carpet, as will be more fully explained below. The cells in the upper block,lcalled the suction-block, communicate with one another through holes 15 in the cell-walls, said holesbeing situated close to the bottom of the depressions, and consequently at a slight distance fromr the carpet. There are, moreover, in the cells of the upper block perforated supports 12 for theA carpet. The upper block is connected with an air-pump throughpa pipe 13. The operation of the `apparatus is as follows: .0n placing the carpet on the color-block and the suction-block on top of the carpet and on applying a sufficient pressure to both blocks to compress the carpet betweem them the colord IOO ing liquids are introduced into the cells of the color-block by means of the pipes 5. The liquids are subsequently made to pass into the carpet by creating suction in the upper block alternatively while simultaneously exerting a pressure on the coloring liquid in the color-block. lVhen the coloring-matter has been thus sucked or sucked and forced through the carpet, s0 as to barely appear on the upper side of the carpet, (for observing which a few glass-covered sight-holes may be provided on the upper side of the suctionblock,) air is admitted to the cells of the colorblock through the pipes 8 and lO, and said air passing upward in the cells through the perforations 9 forms a layer next to the bottom side of the carpet. To admit of this, an ontlet is provided for the coloring liquid from the cells through the same pipe as previously served for supplying it to said cells. To prevent the colors from spattering the carpet when air is admitted, screens ll are applied over the apertures '7. The suction in the upper block meantime is allowed to continue. At the under side of the carpet there is now no other coloring liquid in contact with the carpet than that which adheres to the surface as a thin film. By the continued suction this liquid is also sucked into the carpet, being thus kept from spreading on the removal of the carpet. It is essential that this be done if the completed carpet is to present a perfectly clear pattern. The suction may be continued until the carpet is perfectly dry, heated air being suitably employed for the purpose referred to. The best plan is,however, not to carry the drying operation further while the carpet remains between the blocks than is required for the purpose mentioned above in order that the blocks may not be engaged longer than necessary. The operation described also allows of the treatment of the same piece of carpet several times while it still remains between the blocks by the exchange of liquids. For instance,an impregnating material is first used, then on drying the carpet a coloring liquid, and on a second drying another impregnating Huid, dac. On completing the treatment of one section of the carpet the suction-block is lifted ott and the carpet moved for treatment of another section, dre.

It is evident that the carpet, fabric, or cardboard after treatment may be used for various purposesfor instance, as a covering for articles of furniture, as table-covers,&c. also in the making of chess and checker boards.
