IMPROVEMENT IN MACHINES ECR MAKING CARPET-LININGS.

i Specification forming part of Letters Patent No. 157,852, dated December 15, 1874; application tiled November 20, 1874. I

To all whom it may concern Be it known that I, THOMAS J. MAYALL, of Boston, Suffolk county, and State of Massachusetts, have invented certain new and useful Improvements in Machinery for Making Garpet-Linin g, of which the following is a specification:

The object of my invention is to manufacture, in a speedy and economical way, carpetlining composed of flattened paper tubes provided with a lling of cotton, batting, or lap, or other suitable material, said tubes being placed parallel with one another, and united by strips or tapes extending crosswise of the tubes.

The carpet-lining itself is not here claimed, but is made the subject of a distinct application for Letters Patent.

My lpresent invention relates to mechanism for making one variety of this lining, in which the flattened tubes extend crosswise of the length of the completed lining, and are united by longitudinal strips or tapes. To this end I employ endless aprons and pressure-rolls, which serve to carry along the iiattcned tubes and to press together the same and the binding-tapes, in combination with tape-rolls that deliver the tapes or binding strips between the two aprons, and above and below the flattened tubes, and a pasting, gumming, or cementing mechanism, by which said tapes, before coming in contact with the tubes, are coated with paste or some adhesive material that, when the vtapes are pressed upon the tubes by the action of the apron or pressurerolls, will cause the said tapes and tubes to be rmly united together. Y

The accompanying drawing represents the mannerin which my invention is or may be carried into effect.

Figure l is a side elevation of the machine. Fig. 2 is a longitudinal vertical section, Fig. 3 a plan, and Fig. 4 an end elevation, of the same.

The various parts of the machine are supported in a frame, A, of any suitable structure and formation. The flattened tubes shown at a are fed to the machine preferably from a feed-table, B, provided with a suitable adjustableA gage, b. This feed-table meets the lower horizontal traveling-apron C, which is an endless band passing around end drums CI C2, the latter of which has its bearings in boxes c, adjustable by means of set-screws c', so as to maintain the apron at the proper tension. Above the lower apron, and beginning at a point preferably in advance of the feed-table, is a second apron, D, traveling around drums D1 D2. The two aprons travel in contact with one another, and their drums C2 D2 act as pressure-rollers. Under the drum D1 is another drum, O3, located below the upper face of the lower apron, and this drum and the upper drum D1 act also as pressure-rollers. The journals of drum D2 are mounted in bearings, adjustable like those of the drum G2, and for the same purpose. The aprons on their eXterior faces have a series of transverse ribs or bars, d, which are spaced so that the distance from one to the next shall about equal the width of the flattened tube. The ribs or bars on the upper and lower aprons register or come together, so that when the tubes and tapes pass into the machine, the upper and lower ribs will come together upon those parts of the tapes intervening between the ilattened tubes. The tape-rolls are shown at E for the upper tape-rolls, and F for the lower taperolls. as it is desired there shall be longitudinal binding-strips. Three rolls are shown in the drawing. The rolls of each set are represented as mounted on a single shaft; but in practice I prefer to mount each roll on a separate axis or bearin g stud, from which it may be removed and replaced by a new one without interference with the others. The tapes pass over cylinders G, which revolve in troughs H containing paste or other adhesive material. The cylinders are, of course, provided with doctors to remove surplus paste. The lower tapes c pass up over the cylinderG and around a roller, I, whence they pass under the feedtable to and just above the lower feed-apron, as indicated in Fig. 2. The upper tapes f pass from their paste-cylinder G to and under the drum D1. The various drums of the aprons may be geared or belted together, so as'to revolve in unison.

The operation of the machine is fully shown in Fig. 2. The flattened tubes, which are fed one after the other from the feed-tables onto There may be as many rolls in each set the lower' traveling-apron, rest on the lower tapes e, and when they reach the rolls or drums D1 G3 they meet the upper tapes f, and by the action of said rolls, the tapes are pressed upon the flattened tubes, and the whole are caused to adhere together. The tubes lie in the spaces between the ribs on the apron, and said ribs on the upper and lower aprons come together, so as to compress and stick together those portions of the tapes intervening between the tubes.

Between the two sets of pressure drums or rolls are arranged steam-pipes H above and below the carpet-lining, so that the latter, by the time it emerges from the machine, may be thoroughly dried and completed. This feature is desirable, because it both facilitates the work and prevents liability of the tapes getting loose from the tubes.

I have used the word tape-rolls to distinguish the rolls that carry the binding-strips; but it will be understood that the bindingstrips may be not only tape, but any other suitable material, such, forinstance, as paper.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The described combination of the two traveling-aprons, the pressure drums or rolls, the

feed-table, and the tape-rolls, and pasting de- THOS. J. MAYALL.
