To (1 Z-UhOT/b it may concern:

Be it known that 1, WILLIAM THOMAS HEsKETn, a subject of Great Britain, residing at Stones House, Hayfield, in the county of Derby, England, have invented new and useful Improvements in Machines for Printing Cloth, VValLPaper, and other Materials, of which the following is a specification.

My invention relates to improvements in machines for printing cloth, wall paper and other materials and has for its object to enable a printer to observe and distinguish objects printed on cloth, wall paper and other materials while traveling through the printingmachine.

Hitherto, in calico printing, a speed of about sixty yards a minute is considered the limit because of the diiliculty, even'at that speed, of viewing and distinguishing the objeets printed and detecting any faults of printing, such as imperfections ofregi'ster. llf, however the printer could observe the objects printed in such a way that he would be able to distinguish and detect any imperfections of register or faults of printing, a vastly increased speed and rate of printing couldreadily be attained and the object of my invention is to enable the printer to so observe and distinguish the objects printed. l accomplish this object by the arrangement use and application of a device such as a rotating disk having observation slits or apertures placed in front of the printing machine at a suitable height and close to the cloth or other material as it leaves the engraved roller or other printing surface.

The disk is mounted on a carriage fitted on a traverse screw or otherwise suitably mounted so as to be capable of being moved to and fro across the face of the cloth or other material and stopped at any desired point in it's traverse. The disk isrotatedby worm or other suitable gearing actuated preferably from the driving shaft of the printing machine so that the rotations of the disk synchronize with the speed of travel of the material being printed.

In the accompanying sheet of drawings Figure 1 is av perspective view of a calico which'my invention has been applied. Fig. 2 is a front view of the stationary. masking disk. Fig. 8 is a similar view of the rotating disk and. Fig. 4 is a side view of both disks and the worm gearing for driving the rotating disk. I

On the frame a of the machine I mount in bearings Z) a screw 0 which is driven in either direction as required by open and cross belts, not shown, and the well known arrangement of two fast pulleys d, (1 and 'a loose pulley (P. ()n the screw 0 is mounted a carriage e which is traversed to the desired position to or fro along the face of the cloth f being printed whenever one of the driving belts is on one of the fast pulleys d, (P. A short shaft 9 is journaled in the carriage e and on this shaft is fixed the rotating disk It in which are formed any suitable number, say four, observation apertures h.

To prevent the eye becoming confused I prefer to mount on the traveling carriagee in front of the rotating disk h a masking disk 'L with only a single aperture i which can l :e fitted with a magnirying lens to assist the vision of the observer. This disk i is held against movement by the frictional engagement of its carrying parts but it may be rotated by hand when desired as it is su'lliciently loose to permit such movement.

An electric or other light may be -laced above the traveling carriage e with a re ector, if required, to focus the light on to the part of the printed material to be observed. On the shaft 9 of the rotating disk It is also fiXeda worm wheel j which gears with a worm is mountedin bearings Z on the machine frame a and this worm 7c is driven by bevel gears m from a bevel gear a fixed on a shaft 0 carried in brackets p secured to the frame a. The shaft 0 is driven b a sliding friction wheel (1' mounted thereon 'rom a friction disk 1" fixed on the main shaft or other convenient rotat ing art.

o vary the speed of the shaft 0, and consequently the speed at which the disk h is rotated, the friction wheel q is fitted to slide on a feather key in the shaft 0 and it is moved nearer to or farther from the center of the friction disk 1" by means of a guide bar 3 the boss of which is mounted on a screw 6 journaled at its ends in the brackets p and actua tuated by a hand wheel. a. The lower end of the har s is guided by a rod 4) also supported in the brackets p.

in application the disk can be used in at least three ways for exam le:

First. The disk 1, can be rotated so that a Secondly.

sage of the observation apertures h exactly single Fobservation a erture h therein will pass the eye of the 0 server say about three nmdred times a minute, or to avoid rapid' rotation of the disk ii there may be two, three or more observation slits or a ertures 72- therein, equidistant from each ot ier, and in such case the rate of rotation of the disk may' be reduced. As the objects which are p'rin t-. ed on the cloth are always exactly equidis tant from each other, repeating at a specified distance. it follows that if the printed objects pass at a rate that is a multiple of three hun.-; dred times per minute, the objects will appear to be stationary, although in fact, only a certain number are seen of those that pass.

If, after having made the passynchronize with the assage of the printed objects as-above described, the driving is adjusted by operating the hand wheel 11, so as to cause the disk 'h to rotate rather slower, the

effect will be that the printed objects will appear to be gaining, that is, moving forward rather quicker than the disk. 1

*Thirdly. If, after synchronizing, the motion of the rotation of the disk 71 is slightly accelerated by again actuating the hand wheel u, the effect will be that the printed objects ap ear to be losing, that is, moving slowly bac By utilizing the second and third modes the printer is able to examine the surface of, the-cloth or other material between the printed objects in order to detect printing faults.

What I claim and desire to secure by Letters Patent of the United States is In a machine for-printing cloth, wall paperor other materials 1.. The'combination with .a printing maacross the face of the material .being rinted,

a rotating disk mounted on the trave ing carriage and having any suitable number of observation apertures, a stationary masking disk with a single aperture mounted on the carriage in front of the rotating disk and means for varying the speed of the rotating disk, all substantially as and for the purposes herein set forth.

3. In combination, the traveling carriage e,

the traverse screw 0 and means for rotating the same in either direction, the rotating disk h having any suitable number of observation' apertures h and thenormally stationary masking disk i with a single aperture 6" said disk i being capable of rotary movement and means for rotating the disk'h and varying its speed, all substantially as and for the purposes herein described.

In testimony whereof I have signed my name to this specification in the two subscribing witnesses. WILLIAM THOMAS HESKETH.
