To al?, whom t may concern:

Be it known that I, WALTER H. LUM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hat Tip Rubbing Machines, of which the following is a specification.

This invention relates to a machine for removing the surplus gold, silver, or other metallic leaf used as a finishing or coating for certain kinds of printing.

The invention will be particularly described and referred to in connection with the finishing of what are known as Hhattips or the labels which are inserted in mens hats and which contain the imprint of name and address of the maker or seller, although I wish it to be understood that the same operation may be applied to the printed portions of any material or device, such as silk or satin badges, in which metallic leaf or dust is applied to color the printed matter. The invention involves mechanism for rubbing the tip or other printed device so that the surplus gold leaf or powder is quickly removed without marring the print in any way. As at present carried on this result is accomplished by handwork, the operator using a piece of cloth and rubbing the printed surface several times until the surplus leaf or powder is removed, except where it adheres to the printed characters.

In the accompanying drawings I have shown preferred embodiments of my invention in the following figures.

Figure 1 is a view, partly in side elevation and partly in longitudinal section, of a machine embodying my invention in one form. Fig. 2 is a top plan vi ew of the parts shown in Fig. 1. Fig. 3 is an elevation of one of the guideways or tracks as used in my machine.

Fig.. Il is a top plan view showing a modified form of carriage forming. a part of my machine, and Fig. 5 is a side elevation of the parts shown in Fig. 4.

Referring to the drawings in detail, a represents a flat-top table supported at the four corners by legs a and having throu h the top an opening a2, below which is slidabIy mounted a draw a4, to which is secured a handle a5. On the top of the table in front of the opening a2 is secured a pad a3. Secured in the table-top are two posts b, the upper ends of Which are connected by a cross-bar b', and

bolted to the rear end of the table is a twoarm bracket, in the outer ends of which is mounted a pulley d, over which travels a belt d', which is driven from an overhead shaft or pulley in any convenient manner. On the ends of the shaft upon which the pulley d is fixed are crank-arms c, to the outer ends of which are secured rods c2. Secured to the top of the table are channel-irons e e, having' an upper flange e and a lower flange e2, which form a guideway or track for a movable carriage to be described. The upper flanges are cut away at c3 and e4, and on the upper flange adjacent to the cut-away portion e* in each of the rails e is a pivoted link e5, which is inclined rearwardly and has its lower end resting on the flange e2, forming an inclined plane, as clearly shown in Fig. 3. Between the tracks formed by the channelirons e e is slidably mounted a carriage which is composed of side bars f, a front cross-bar j", and a rear cross-barf2, all rigidly connect- `ed together to form a rectangular frame. The side bars f extend forwardly ofthe crossbarjl2 and have formed therein bearings for the shaft of the roller-brush g. The rear ends of the side bars f have upward extensions f3, in which is mounted a shaft f u, which carries a yoke f4, upon which are mounted grooved rollers f 5. A portion of the shaftj'1l is surrounded by a spiral spring f G, one end of which is secured in the side barf, and the other end bears against the under side of the yoke f4, so that the tension of the spring is exerted to hold the yoke upward, as clearly shown in Fig. 2. At the rear side of the cross-bar f2 are lugs f7, between which are pivoted the forward ends of the rods or links c2. The carriage is mounted on the rollers f1", which run between the upper and lower flanges of the track-bars e until in the forward movement of the carriage they reach the inclined links c5, when said rollers ride on said links and along the upper flange c until they reachV the cut-away portion e3, when they drop to the lower flange.

In Figs. l and 2 I have shown means for rotatin the brush g and for supporting the forwar end of the carriage, which I will now describe. On one end of the brush-shaft is mounted a pulley g, over which travels a round belt g2, which passes under the grooved pulleys f 5 and is driven by suitable pulleys on an overhead shaft. (Not shown.) The belt g2 is kept taut by a coil-spring f acting on IOO the yoke f4, as heretofore described. In order to cushion the drop of the carriage through the cut-away portion e3 at the end of its forward movement, I provide a cylinder 7L, hinged at h2 on the cross-bar b and having working therein a piston h, the lower end of which is pivoted to the cross-bar f of the carriage. The head of the piston fits sufficiently tight in the cylinder h to cause more or less resistance to the downward drop of the carriage, as will be readily understood.

In Figs. i and 5 I have shown a modified method of driving the brush, which consists of grooved pulleys g4, secured to the rollers at the rear of the carriage, and pulleys g', secured to the ends of the shaft-brush g. Endless belts gwhich travel over said pulleys g and g4 on each side of the carriage, and the rotation of the rollers f 1 asthey are drawn between the flanges e e2 drive the grooved pulleys g4, hence transmit motion, through the belts g2,to the pulleys g. The rear crossbar f2 of the carriage is provided with an eX- tension f 8, upon which is adjustably mounted a counterweight fg, which servesto balance the weight of the forward part of the carriage and the brush, thus preventing violent dropping of the brush in the forward movement of the carriage.

In the operation of my machine it will be seen that the carriage is reciprocated between the tracks e by the action of the drive-rods c2, driven from the cranks c on the shaft of the pulley b. In the forward movement of the carriage the front rollers ride up on the links e5 and along the upper iiange e until they reach the cut-away portion e3, when they drop, and thereby permit the brush g to come in contact with the printed tip or other device that-has been placed on the mat a3 for the rubbing operation. The roller is then rotated in the direction indicated by the arrow in Fig. l, whereupon the surplus goldleaf or other material applied as a coating to the printed tip is removed by the revolving brush and caused to fall into the drawer a4.

The carriage then retreats and a new tip is placed in position for a second similar operation.

So far as I am advised, I am the first to provide a machine for accomplishing the results above described, and I therefore do not wish to be limited to the specific construction shown and described; but

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

l. In a machine of the class described, a table, a reciprocating and tilting carriage arranged above the table, a brush rotatably mounted on said carriage, means for rotating the brush and means for reciprocating and tilting the carriaffe.

2. In a machine of the class described, a table, a reciprocating carriage adapted to be raised at one end and to fall by gravity, means for modifying the action of gravity on the carriage, and means for reciprocating the carriage.

3. In a machine of the class described, a table having an opening therein, a slideway secured to said table, a carriage adapted to reciprocate in said slideway, a cylindrical brush rotatably mounted at the forward end of said carriage, means for reciprocating the carriage and means for rotating the brush.

4:.- In a machine of the class described, a table, a slideway secured to said table, a carriage adapted to reciprocate in said slideway, means for raising the carriage in its forward movement, a brush mounted at the forward end of said carriage and means for recipro cating the carriage.

5. In a machine of the class described, a table, a slideway secured to said table, a carriage adapted to reciprocate in said slideway, means in said slideway for raising the carriage in its forward movement and permitting it to drop in its rearward movement, a brush mounted at the forward end of said carriage and means for operating said carriage.

6. In a machine of the class described, a table having an opening therein and a drawer arranged under said opening, a slideway secured to said table and extending along each side of said opening, a carriage slidably mounted in said slideway, means for raising and lowering the carriage relative to said slideway, means for sliding the carriage, a cylindrical brush rotatably mounted in said carriage and means for rotating said brush.

In testimony whereof I affix my signature in presence of two witnesses.
