COATING-MACHINE.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed February 28, 1906. Serial No. 303A75.

To all whom it may concern:

Be it known that I, ALBERT J. FORD, a citizen of the United States, residing in New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Coating-Machines, of which the following is a specification.

This invention relates to coating-machines for covering metal sheets with varnishes, oils, printing-ink, or other suitable substance; and the invention relates more specifically to certain improvements in the coating-machine for which Letters Patent of the United States No. 802,745, dated October 24, 1905, were granted to me, said improvements being designed with the view of simplifying the construction of the machine by dispensing with one of the transfer-rollers without'impairing the effective working of the machine, and for this purpose the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of my lmproved coating-machine. Fig. 2 is a vertical longitudinal section through the three rollers employed in the coating-machine, and Fig. 3 is an end elevation of the coating-n1achine Similar letters of reference indicate corresponding parts in the three figures of the drawings.

Referring to the drawings, A represents the upright side standards of my improved coating-machine. The standards are united in the usual manner by transverse tie-rods a. An iron supporting-roller B for the sheets to be coated turns in suitable bearings of the side standards A, the sheets to be coated being fed to the supporting-roller B over an inclined feed-table O, which is supported by inclined arms O, which form parts of the supporting-frame of the machine. A scraper B is supported in brackets of the side standards and adjusted relative to the circumference of the supporting-roller B by a setscrew provided with a hand-wheel, said set screw turning in a screw-socket hinged to a transverse shaft of the connecting and supporting arms of the feed-table. A coating roller D is supported in j ournal-boxes in the upper part of the side standards A and is rotated 1n contact with the supporting-roller B. A fountain-roller E for the varnish, oilcolor, or other substance to be transferred is supported in suitable boxes at the opposite side of the coating-roller, the supportingboXes for the shaft of the fountain-roller E being arranged below the supporting-boxes of the coating-roller, so that the center of the shaft of the fountain-roller and the contact line of the latter with the coating-roller are slightly below the center of the shaft of the coating-roller.

A fountain F for the varnish, oil color, or other substance to be transferred to the sheetmetal sheets is supported on brackets a of the side standards A, said fountain extending laterally slightly beyond the contact between the line of contact of the fountain and coating-rollers and into close proximity to the latter roller, so as to catch any surplus varnish or other substance which drips from said rollers. The fountain F is located above and to one side of the axis of the supportingroller, as shown, so as not to interfere with the passage of the sheet between said roller and the coating-roller. The lower part of the fountain-roller enters into the varnish or other substance in the fountain F, so as to take up the substance to be transferred. The surplus varnish or other substance runs along the circumference of the fountain-roller and drops back into the fountain instead of dripping on the coated sheets as they pass under these rolls, as it would otherwise do. Any varnish transferred to the supportingroller is removed by the scraper, which is placed in contact with the supporting-roller and dropped into a drip-pan G, which is supported on the supporting-frame below the supporting-roller and provided with a discharge-pipe, from which the same is con ducted off in a suitable way. The sheets after being coated are delivered onto tapes t, which carry off the sheets for drying. At one side of the outgoing end of the machine is supported a horizontal table H on a suitable bracket-arm h for placing the can containing varnish, color, or printing-ink on the same, so as to be readily at hand for supplying the same to the fountain F and from the same to the coating-roller. The deliverytapes pass over a suitable roller supported between the upright standards A.

The rotary motion is imparted to the supporting-roller, coating-roller, and fountainroller by suitable gear-wheel transmission by tain. A uniform coating is thereby transthe driving-shaft S of the machine, which is ferred to the sheets, notwithstanding the fact provided with a fast and loose pulley in the usual manner, thus receiving suitable motion from a power-shaft.

The metal sheets or plates to be coated are fed from the inclined feed-table through between the supporting and' coating rollers, with the face to be coated uppermost, so as to receive the coating from the coating-roller. The coated sheet or plate passes onto the delivery-tapes and is carried off by the same. Any varnish or color that is transmitted by the coatingroller to the supporting-roller when no sheets are being fed is scraped off by the scraper B and dropped into the drip-pan G, which keeps the back ofthe sheets perfectly clean. As the axis of the fountainroller is located somewhat below the level of k that of the coating-roller, the surplus varnish or other substance is returned to the supplyl fountain, the inner end of which is located beyond the point of contact of the fountain and coating rollers, only such quantity of varnish or color being carried along by the coating-roller as is required for the proper coating of the sheets fed through the ma' chine, the surplus naturally being crowded onto the surface of the lower part of the trans fer-roller and dropped back into the founand the construction of the machine is considerably simplified.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a machine for coating sheet metal, the combination, with a supporting-roller, of a coating-roller arranged above the same and movable in contact therewith, a fountainroller at one side of said coating-roller and said fountain-roller and extending laterally slightly beyond the line of contact of the lat-' ter with said coating-roller into close proximity to the latter, said fountain being 10- supportingroller.
