MACHINE FOR PRINTING SHADE FABRICS.

SPECIFICATION forming part of Letters Patent No. 440,413, dated November 11, 1890. Application filed February 5, 1890. Serial No. 339,248- (No model.)

T at whom it may concern.-

Be it known that we, JOSEPH N. \VIGGIN, of Orange, in the county of Essex and State of New Jersey, and CHARLES A. GOLLORD, of

the city, county, and State of New York, citi- Zens of the United States, have invented a new and useful Improvement in Machines for Printing Shade Fabrics, of which the following is a specification.

to In the process of making up ornamental window-shades in quantities it is usual to cut the shade fabric into standard lengths approximating the heights of windows and to print upon a portion of one face an ornament or design and to afterward set aside the printed fabrics to dry before the same are fastened to the rollers. Difficulties have heretofore been experienced in successfully printing the shade fabric and keeping the unprinted portion away from the face of the types on the bed, also in receiving it from the printing-machine and drying the same afterward; and the object of our invention is to overcome these diiiiculties.

lVe employ in connection with a reciprocating bed and impression-cylinder, forming part of a cylinder printing-press of any desired and well-known kind,bands and springactuated rollers or equivalent yielding devices 0 for holding up the fabric against the reduced face of the impression-cylinder While the reciprocating bed is returning, endless tapes and slat conveyers for receiving the printed fabric from the cylinder and delivering it from the press, and rocker-arms actuated from the shaft of the impression-cylinder and adapted to receive and hold slats upon which the printed shade fabric is received in a hanging, folded, or looped condition to be thereafter conveyed away to be dried.

In the drawings, Figure 1 represents by an elevation and partial section our improvements. Fig. 2is a plan view of the same with the feed-board removed, and Fig. 3 is an eleva- 4 5 tion of the bands and spring-actuated rollers.

A represents the side frames, B the drumcylinder, 0 the traveling-bed, and D the feedtable, of a cylinder printing-press of usual construction, which parts do not require fur- 5 ther description.

The cylinder 15, is as usual, made with about one-third of its circumference of increased radius, and by this portion of the surface the impression in printing is given. I have shown this portion at B, the balance of the surface at B being of reduced radius.

There are brackets at a a at each side of the machine secured to the upright A. The rod 1 and shaft 2 pass across the face of the cylinder, and their ends pass through and are connected to the said brackets a a, and between and secured to said shafts there are placed elastic straps b or equivalent yielding devices There are rods 8 at passing across the face of the cylinder, whose ends are secured in the side frames A, and elastic straps c or equivalent yielding devices are secured to and extend across between these rods 3 4, one strap near each end of the cylinder beyond the width of the printing-form upon the reciprocating bed.

Upon one end of the shaft 2 are secured companion arms cl d, and a metal roller f is journaled on a short shaft at the end of the arm cl. A helical spring 6, whose ends are connected, respectively, to the bracket 0L and end of the arm (1, acts to hold the roller f against the face of the cylinder B, or ways upon the same. There are other arms d similar to the arms d, also upon the shaft 2 and at intervals across the face of the cylinder, and on their ends rollers f, having peripheries or tires of rubber. All of the rollers f f run over the surface of the reduced portion of the cylinder B; but the rollers f are raised from the surface of the large portion of the cylinder by the roller f, running upon an elevated strip orway 5 upon the surface of the increased portion of the cylinder at one end. The elastic springs 12 c or equivao lent yielding devices also remain against the surface of the cylinder.

Mounted in adjustable bearings upon the frame A are shafts 6 7, and upon said shafts are sprocket-wheels h h in pairs, between and around which are chains i, having slats z" placed at intervals and connected at their ends to said'chains, and we provide rests or slideways 70 for the higher portion of the chains to run on toinsure contact between the chains and tapes, hereinafter described. A pair of wheels IL2 is mounted upon the shaft 6 and a similar pair upon the shaft 7 near the sprocket-wheels h h, and these wheels are notched in their peripheries for the slats i, and xund a portion of these Wheels 7L2 run ta "wove and outside of the slats t". The grip nd gripper-bar of the sprocketwheels h and usual construction. Above these chains and sprocket-wheels are tapes Z and a roller-shaft Z and rollers Z and a shaft for the same in suitable bearings in the frame of the machine. The rollers Z and their shaft are in swinging frames adjustable so as to tighten the tapes. \Ve provide a cam m upon the shaft of the impressioncylinder B and a rocker-arm n, pivoted near its center at 8 to the frame A, having aroller 'n at one end adapted to engage the surface of the cam on.

We provide frames 0, secured to the floor or other convenient place, and an arm r, secured to a shaft 9, outside the frames 0 and adaptedto swing back and forward. Arms are secured to the shaft 9, between the frames 0 by bolts or set-screws. A rod 3 is pivoted at 10 11 at its ends to the arm r and lower end of the rocker-arm n, and we provide a rod 25, pivoted at one end to the arm 1" and passing through a slide-block 12, and having a helical spring u around said rod t between the block 12 and a pin 13. At the upper ends of the vertical arms r upon the shaft 9 there are bracket-hooks 0 adapted to receive strips of woodsuch as lathwhich extend across the machine. At t we provide an adjustable rest-block, extending across between the frames A and secured thereto.

The operation of the machine is as follows: The shade fabric is laid upon the table D and one piece at a time is fed to the grippers of the cylinder B, and as said cylinder revolves the fabric is carried between its surface and the bands I) and rollers f and the edge bands 0, and as the enlarged portion of the cylinder passes the lowest point the portion of the shade fabric upon the same is printed upon in any desired ornamentation. The cylinder now continues its rotation and the bed finishes its movementin one direction and starts to return. As the bed returns, the printingsurface of the bed passes beneath the cylinder in the opposite direction to that of the cylinder. The shade fabric is now held by the elastic bands b, the rollers f, and the edge bands 0 or equivalent yielding devices against the reduced face of the cylinder 13 away from and above the reciprocating bed and its printing-surface, so that the parts move clear of each other. The advancing end of the shade fabric is released from the grippers of the cylinder B and delivered to the grippers of the wheels 7L2 upon the shaft 6, and is by them carried up upon the tapes and slats v) and delivered into the bight of the slats t" and tapes Z. The shade fabric is now carried along upon the slats by the chains to and around the rollers or wheels it upon the shaft '7, the parts having been so timed in their movement that the printed under surface of the shade fabric comes at a point where a slat has been omitted, or, in other words, between the slats 14 15, where there is nothing to smear the printed surface. As the printed shade fabric is delivered over the rollers and nearly half of its length has passed down in front of the rest-block v, the arms 1", carrying a slat of wood in the bracket-arms T are by the cam m and other parts, as heretofore described, moved quickly up to and pressed against the said rest-block, thus bearing the shade past the vertical line of its fall and engaging the shade fabric at or near the center. As the shade fabric continues its movement, it falls over the other side of the slat held by the arms 9*, as shown in dotted lines in Fig. 1, in the form of a fold or loop with the ends hanging down. In this position the arms 0" and r are held by the cam m against the spring a as compressed. As the parts return by the action of the cam and spring a to the position in full lines, Fig. 1, the

loop of shade fabric is carried back, where it can be removed upon the slat of Wood for drying, and another slat of wood inserted and the operations heretofore described be repeated.

We claim as our invention- 1. The combination, in a cylinder press, with the reciprocating bed and. impressioncylinder having a portion of its surface of increased radius for giving the impression, of yielding tension devices pressing toward the under surface of the cylinder, whereby the shade fabric or other article printed upon is held against the reduced portion of the cylinder and away from the types during the return movement of the reciprocating bed, substantially as set forth.

2. The combination,with the reciprocating bed and impression-cylinder, and the frame A, of the frames a an, elastic bands I), and edge bands 0 and their shafts, the arms cl d (P, helical spring 6, and rollers ff, substantially as set forth.
