MACHINE FOR PRINTING IN GOLD, SILVER, OR OTHER POWDIERS.

SPECIFICATION formingpari; of Letters Patent No. 710,693, dated October 7, 1902.

Application filed December 28, 1901. Serial No. 87,638. (No model.)

To r/,ZZ wtom/ it 777,601/ concern:

Be it known that I, THOMAS I-IooLEv, a subject of the King of Great Britain, residing` at Stockport, in the county of Chester, England, (whose post-office address is 3 and 5 Duke street, Stockport, aforesaid,) have invented new and useful Improvements in and Connected with Machines for Printing in Gold, Silver, or other Powders, (for-which I have made application for patent in Great Britain, No, 24,765, dated December 5, 1901,) of which the following is a specification.

My invention relates to apparatus for printing in gold, silver, and other powders, wherein the powder is fed onto a form or block which is first heated to a suitable degree, and the board or other substance to be blocked or printed is covered with a coating or varnish that will melt under the heat of the said form or block, and thus cause the said powder to adhere in the design required, and the said powder is caused to evenly adhere to the said form or block by applying thereto a little oil or the like substance which will freely transfer the powder to the hoard or other substance to be blocked or printed; and the object is to provide means for more efficiently carrying out the aforesaid operations in ,respect of block-printing, so that the form or block applying the oil and powder will always remain relatively in the same position, and thus facilitate the blocking or printing of any thickness of board or material. I attain this object by the mechanism illustrated in the accompanying two sheets of drawings, in which- Figures l and 4 are longitudinal sections, Fig. 2 a plan, Fig. 3 an end view, and Fig. 5 a side view, of my improved block-printing machine; and Figs. 6 and 7, a side view and a section, respectively, of a detail thereof.

Similar characters refer to similar partsV throughout the several views.

d ct are the side frames. b is the bed; c, the work-table on the said bed; d, the printing-block with removable face e and rendered vertically adjustable, as usual. f represents the cams for raising the bed; g, Figs. 2 and 3, the lever by which the said cams are actuated; 7L, the powder-supply roller; i, the

y upon the table c to rise and fall therewith I powder-roller, and k the oil-roller of the machine.

Now instead of employing the oil-roller L, powder-roller t', and powder-supply roller It suspend the same from the printing-block d, say, in the following manner: To each side of the printing-block d I secure a bracket l, having each a slot m, parallel with the face ofthe said block. In each of these slots I employ a slide n, carrying each two springsupported bearings o p, in which are mounted the powder-roller and oil-roller 7c and the vertical position of which may he regulated by the nuts q. The slides n and table c are so connected with each other that when reciprocating the table c the slides n, and thus the rollers 't' and 7o, will always move with it in any vertical position of the printing-block d and also allow of the table c being raised and lowered without disconnecting the latter from the slides n. This may be effected, say, as shown in Figs. l and 2, by forming the respective slide ends with V-shaped projections fr engaging in correspondingly-shaped vertical grooves s, formed in the table c. Each of the said brackets has outside a rail t, to the front end of each of which is hinged an inoline n, placed under the influence of a spring o, which tends to pull the same against a stop The shaft ends a; of the oil-roller k are made of such a length as to project across the said rails t, so'that when pushing the table c Ytoward the powder-supply roller 72, they will meet the said inclines and be guided underneath the said rails t, (see dotted lines, Fig. 4,) and thereby the oil-roller depressed sufficiently to clear the surface of the printingblock d, while the table c of the machine moves toward the powder-supply roller 7L, which latter is mounted in a frame y, secured to the back ends of the brackets Z and partly inclosed by a cover a, hinged thereto. Vhen the table c has arrived at the back of its bed b, the shaft ends a: ofthe oil-roller 7c leave the rails t, and the oil-roller 7c thenrises again to its original position, (see full lines, Fig. 4,) while the powder-roller i has come into contact with the powder-supply roller 7L and is furnished thereby with powder.

IOO

To the shaft ends of the powder-roller t' is hinged a trough l, Fig. l, formed With arms 2, which when the said table has arrived at the back contact with stops 3, which cause the said trough to tilt and expose the side of the powder-roller i, so as to allow of the supplyroller 71, furnishing the latter with powder.

Each time the cam-lever g is actuated the powder-supply roller 7L is rotated by a rack 4, hinged to the said cam-lever and in gear with a pinion 5, (see more particularly Figs. 6 and 7,) having a ratchet-wheel 6 loosely mounted upon the powder-supply-roller shaft 7, and a disk 8, carrying a pawl 9, engaging in the ratchet-wheel 6 and secured upon the shaft 7.

On the return of the table c the oil-roller k passes rst over the printing-surface of the block d and coats the design thereon slightly,

'and the powder-roller z', following the same,

then applies the powder, as will be readily understood. A

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In an apparatus for printing in gold, sil ver or other powders in the manner as hereinbefore referred to, a horizontal bed, a worktable adapted to be reciprocated on the said bed, a vertically-adjustable printing-block above the latter, an oil-roller, a powder-roller and a powder-supply roller suspended from the said block, all combined substantially as and for the purpose set forth.

2. In an apparatus for printing in gold, silver orother powders in the manner as hereinbefore referred to, a horizontal bed, a worktable adapted to be reciprocated on the said bed, a verticallyadjustable printing-block above the latter, an oil-roller, a powder-roller and a powder-supply roller suspended from the said block, a slotted bracket ou each side of the printing-block, a slide in each of the said brackets adapted to be reciprocated therein, bearings carried by the said slides in which the said oil-roller and powderrollerare mounted adjacently and bearings on the back ends of the said brackets in which the said powder-supply roller is mounted, all combined substantially as and for the purpose set forth.

3. In an apparatus for printing in gold, sil- Ver or other powders in the manner as hereinbefore referred to, a horizontal bed, a worktable adapted to be reciprocated on the said bed, a verticallyadjustable printing-block above the latter, an oil-roller, a powder-roller and a powder-supply roller suspended from the said block, a slotted bracket on each side of the printing-block, a slide in each of the said brackets adapted to be reciprocated therein, bearings carried by the said slides in which the said oil and powder rollers are mounted adjacently and a connection between the said slides and work-table for horizontally reciprocating the said rollers jointly, all combined substantially as and in the manner hereinbefore set forth.

4. In an apparatus for printing in gold, silver or other powders in the manner as hereinbefore referred to, a horizontal bed, a worktable adapted to be reciprocated on the said bed, a vertically adjustable printing-block above the latter, an oil-roller, a powder-roller and a powder-supply roller suspended from the said block, a slotted bracket on each side of the printing-block, a slide in each of the said brackets adapted to be reci procated therein, bearings carried by the said slides in which the said oil-roller and powder-rollerare mounted, and rails on the sides of the said block, the shaft ends of the said oil-roller extending across the same and inclines at the front end of the said rails adapted to guide the said shaft ends underneath the said rails on the forward travel of the Work-table, all combined substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

THOMAS HOOLEY.
