IMPROVEMENT. IN.MAQH INER Y IOR PRiN'I-ING-OIL-OLOTH, 8:9.

The Schedule yoferrcdto in thus Letters Patent and milling :Plrl: 9| 1 im To all whom it may concern.-

Be it known that I, inthe county of Essex and State of New Jersey, have invented a new and improved'lress for Printing Oil- Glot-hs, Table-Clothes, &c.; and I do hereby declare that the thllowing is a full, clear, and exact descripjionthereof, which will enable others skilled in the art to make and use the samc,.refercnce being bad to 7 the accompanying drawing forming part of this specification. a 1 g My invention relates to a-printing apparatus for oil-cloths and-other fabrics, and consists in certain improvements, which will first he described in connecfiOILWith all that is necessary to a full understanding thereof, and then clearly specified in the claim.

In, the accompanying drawing- Figure 1 representsa side elevation of my improved oil-clo'th-printing machine. 7

Figure 2 is a vertical longitudinal section of the same. r I

Figure 3 is-alplan or top view of the same.

Figure 4 is adetail vertical transverse section of one of the coloring devices.

Figure 5 is a detail side view of asectional printing-cylinder. v

Figure 6 isan endview of the same.

Figure 7 is a detail longitudinal section of the clamp for holding the fabric.

Similar letters of reference indicate corresponding parts.

v A, in the drawing, represents themain supporting bed or floor of my niacliine.- Upon it are supported the three main divisions of the machine. These-db visions are-first, the coloring; second, the printing; and third, the cloth-holding machine. Only the printing division is secured upon a stationary frame, B. The other divisions are upon sliding frames 0 and D respectively.

In the'fixed frame B are hung three (more or less) horizontal axles E E E, all vertically above each other.

Upon each axle E is fitted a printing-cylinder, F. When a cylinder, F, has the full length of the axle between the upright bars of the frame B, it is intended to printthe full width of the fabric.

The cylinders may, however, as in fig. 5, be made in shorter pieces, to print but one-half or one-third of the width where the design is repeated in a horizontal direction. Insthis latter case a short cylinder, F, is fitted upon an axle, E, andislocke'd to either end, or to the middle of the same,.by means of aspringcatch, a, which is secured to one end of the cylinder,

as shownin fig.'-6.

The axle E. is provided with a feather, b, to prevent the cylinder from turninglcosely on it. This Josnrn KRAFT, of h icwark,

feather" has notches to receive the spring catch, as indicated in fig. 5.

' The pinsc c,"w-liicl'r imprintt-he required design upon the fabric, are set upon the faces of the printingcylinders F or On the cylinder F, which extends throughout the entire width of the frame, these pics sweet so as to produce but one half the design for each color, as the reverse of it can be printed by the same pins, by. reversing the position of the fabric.

The fabric to be printed is held on a -frame,G, which is, by a pin, H, pivoted to the sliding frame 1). Fonr.(more or less) horizontal rollers, d d, are hung in-the frame G, and-over them the fabric I is drawn in such manner that it is properly stretched in a straight line, directly infrOnt-ot' the priuting-cylin-- 'ders.

' lt'is veryimportantthat'the cylinders F should be so set that their respective designs-arc applied to the fabric in the desired succession. Forthis purpose I apply to the end of each axle E a worm-wheel, e, firmly keyed to the axle. I

This worm-wheel gearsinto a worm, j, which is atfixed'to a wheel, 'g, hung loose, upon the axle. The wheels 9g of the several'a xles are connected with each otherby meaus'of a connecting-rod, h, which is attached to crank-pins, t i, that project from'said wheels, as shown. The cylinders will thus all revolve simultaneously.

"In order to set the printing position of each cylinder with reference to that of all others, it will only be 'necessary to turn the worm f of such cylinder, and to thereby turn the axle -E within. the wheel g, without disturbing-the latter,-

1 When the fabric hashccn printed with one-half design, theframe GiS- turned on the pin H to reverse the position of the fabric. The motion of the fabric is, atthe"'same time, also reversed, and thereby the half of the design is produced.

Motion -is imparted 'to one of the rollers, 11, by means of 'agear-wheehj, on the frame -B, the said gear-wheel meshing into=a similar ,wheel, K, that is on the end of the rdller cl. 'On the opposite end of another roller, 11, is} mounted another toothed wheel, z,-which, when the frame G is reversed, is brought into contact with the wheelj, to provide for the further but reversed motion of the fabric.

The fabricto be;printed is, from below, brought to the frame G,'and secured to pointed pins m m that project from a bar, n,.the said bar being secured to a belt,' o, which passes around the roller 02. The fabric. is then laid around the said belt 0, and is then secured to a toothed roller, J, which is hung in the frame G as shown. By turning the'said roller J the fabric will be'stretched, and can then be clamped, with its other end, to the belt 0', by a toothed hinged clamp, L. It is then cut off orscparated from the roller J, and in position. for printing. A pair], 1), meshing into a ratchet-wheel, 'r, on one of the rollers (1,, prevents the fabric from getting loose from the pins m-{WllllG it is being stretched by the roller J.

Some or all of the rollers cl are hung in slots and adjustable therein, to keep the belt 0 properly stretched.

The frame 1) is, with all 'of its appendages, made to slide on the bed A, and is, by a rack, 8, United with a worm, M, by means of which'it can be carried away from the printing apparatus, as in fig. 2, to allow the same to'be reached.

The coloring part of the machine is all arranged in the sliding frame 0, which is, bya rack, t, and toothed wheel, N, made adjustable toward or away from the printing frame; also, for the purpose of allowing access to all the parts.

The-coloring apparatus for each printing-roller consists of an endless apron, O, hung upon two rollers, P and It, of whichthe lower one, P, turns in a reservoir or'yat, S, that contains the color. Each reservoir is made to slide into its place by being suspended from rails, 21 a, that are formed on the frame 0. By

means of screws, '0 c, which are arranged in cars at the ends of each reservoir, the position of each reservoir can be adjusted to be more or less oblique. Thus, if the apron should happen to be slightly thicker on one side than atthe other, so that it might tend to run off the rollers, it will be necessary to shift the lower roller with the reservoir, for counteracting this effect. v

A sliding scraper, T, is arranged on each apron O, for the purpose of scraping the superfluous color from the same. It can be adjusted for greater or lesser pressure by means of screws or, and is drawn against the apron by springs x.

The upper rollers R are at their ends provided with toothed wheels, 3, which mesh into the wheels g on the corresponding axles E,'as shown in fig. 1.

Each roller R is hung in slides, 11 y, that are fitted into the frame 0, as indicated in fig. 4.

Having thus described my invention- I claim as new and desire to secure by Letters Patent sectional printing-rollers I F, which hare spring'{ catches a, as set forth.
