MACHINE FOR APPLYING PAINT T0 EMBOSSED DESIGNS.

To all whom it may concern:

Be it known that 1, JOHN ENGEL, ac1t1- zen of the United States of America, residing at Green Bay, in the county of Brown and'State of Wisconsin, have invented certain new and useful Improvements in Machines for Applying Paint to Embossed Designs, of which the following is a specification, reference being had therein to the ac companying drawing.

The invention relates to a machine for ap-' plying paint to embossed designs and is especiall used for painting the figures on license plates for vehicles.

It is an object of the invention to provide a plurality of rollers over which the plate to be painted is moved so that in the passage of the plate the embossed parts of the latter receive paint from the various rollers.

A further object of the invention embraces the provision of means for moving a plate in functional relation to the rollers so that paint is applied in a uniform and effectual manner to the embossed portions of the plates.

It is also an object of the invention to provide means for scraping the operative surface of the rollers for the purpose of evenly distributing the paint adhering thereto.

To the accomplishment of these and related ends the invention comprises the means described in the following specifica tion and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of the machine constructed in accordance with my invention.

Fig. 2 is a longitudinal section of the Ina-- chine- Fig. 3 is a top plan view. 1

Fig. 4 is a section on the line 44 of Fig. 3, and

Fig. 5 is a detail of the driving shaft and pulley.

Referring to the several figures in the drawings, 1 designates a standard for the support of a frame 2 comprising side plates 3 and 4. To the side plates angular members 5 are secured which overhang with a horizontal leg the space defined by the side plates 3 and 4 and which terminate in ways 6 to act as guiding means for belts 7 trained around pulleys 8 and 9 respectively mounted at the front and rear ends of the maspeeification of Letters Patent.

chine. The sidewalls 3 and 4 of the frame 2 carry a plurality of rollers lo reierably, although not necessarily made of rubber and secured on shafts 11 which project through the side walls of the frame. Each shaft 11 is extended beyond the side wall'3to carry a bevel gear 12 in mesh with the bevel gear 13 secured to a shaft 14 arranged at one'side of the machine and extending parallel to the longitudinal axis thereof. The e'ppo site end of the shaft 11 is journaled in abracket 15 adjustablysecured to the side plate 4. As indicated in Fig.- 4 a plurality of screws 13 projectingthrough slots in the bracket 15 secure the latter in adj usted position on the side wall and aset-screw 17 in the flange 18 of the bracket 15 engages the bottom plate of the frame 2 and serves as a means for shifting the bracket whereby a minute adjustment of-the roller 10'may be effected. The shaft 14 carries at its ex tremity a bevel gear-19 in mesh with abevel gear 20 secured to the drive shaft2l. A pulley 22 isprovided, on the shaft-21 and receives rotative power from any convenient source. The shaft 21 is also equipped with a pulley 23 which is encompassed by a belt 24 trained around the pulley 8.

As indicated in Fig. 2 an idler 25 at the free end of a lever 26 is held inengagement with the belt 24 under the action of a helical spring 27 which interconnects the opposite ends of the lever 26 with the frame and thereby serves as a tightener for the belt 24. The lever 26 is pivotally interconnected intermediate its ends to a guide member 28 which at its upper side has grooves 29 through which the belts 7 pass. The latter are trained around guide pulleys 36 which are arranged at convenient places on the underside of the frame 1.

In order to prevent the excessive accumulation of paint on portions of the roller surfaces, means is provided to the eifect of equal distribution of the paint therein. This means comprises plates 30 having an end portion 31 in engagement with the roller 10 and secured to the frame 2 by a screw 32 passing through an angular plate 33 which at its upper end is equipped with set screws whereby adjustment of the plate end 31 relative to the roller 10 may be effected.

As indicated in the figures the rollers are arranged to be partly received in receptacles 34 supported on the frame 2 by legs 35.

The rece tacles 34 are filled with paint to a level su cient to insure contact thereof with the lower portion of the rollers.

The operation of the machine is as follows:

Power being applied to the pulley 22 of the drive shaft 21 the belts 7 will be rotated by the agency of the drive belt 24 interconnecting the roller 8 and the pulley 23 of the drive shaft. Simultaneously upon rotation of the drive shaft the longitudinal shaft 1a is rotated whereby the several rollers 10 are placed in rotation. The plates having the numbers embossed, are placed on the belts 7 such that the embossed figures point downwardly and in the travel of these plates they are suzcessively placed in contact with the rollers 10 of which by way of example three are indicated in the drawing. In the passage of the plate the latter is manually pressed down on the roller. It is obvious that by the employment of the machine a great number of plates may be painted in a convenient and efiectual manner in a comparatively short time.

The rollers 10 are driven with the speed of the driving shaft, being directly geared therewith, and the belts 7 trained around the pulleys 8, 9 travel at the same rate of speed whereby the painting of the embossed part of the plate conveyed by the belts is effe tively carried on.

While the drawings illustrate the preferred embodiment of the invention, alterations will readily suggest themselves to those versed in the art. It is therefore my intention to include all changes constituting departures within the scope of the invention as indicated in the appended claims.

I claim:

1. In a machine of the haracter specified, a plurality of rollers, means for adjusting said rollers in vertical direction, means for supplying said rollers with paint, a plurality of plates having an end portion adapted to engage said rollers for evenly distributing paint on the surface of the rollers, means for adjusting the engagement of said plates with said rollers, and a plurality of belts adapted to carry the work in successive contact with said rollers.

2. A machine of the character specified. a plurality of rollers, means for adjusting said rollers in vertical direction, means for supplying said rollers With paint, a plurality of vertical plates having their lower ends secured to a frame and their upper free ends bent to engage said rollers for evenly distributing the paint on the surface of the rollers, a plurality of set-screws for adjusting said plates with said rollers, and a plurality of belts adapted to carry the work in successive contact with said rollers.

In testimony whereof I hereunto affix my signature.

JOHN ENGEL.
