APPARATUS FOR FORMING ROLLERS FOR PRODUCING A REPETITION OF DESIGNS BACKGROUND OF THE INVENTION This invention relates to the manufacture of rollers having specific surface designs, and more particular to rollers used in treating surfaces with liquid like material wherein the materials are to be repetitively applied in given design configurations.
FIELD OF THE INVENTION This invention is directed to new and useful improvements in decorating devices and more particularly to the manufacture of such devices used for the marking of surfaces with liquids such as oil and water colors in connection with painting, varnishing or other manner of decorative surfacing.
DESCRIPTION OF THE PRIOR ART At the present time rubber rollers with porous and liquid retaining surfaces have been used for applying liquids to various objects. Some of these rollers have been manufactured by incorporating within the rubber compound of which the roll surface is formed different additional materials. These materials are preferably of an expanded or hollow nature since such particles have been found to be not only frangible when the roll surface is ground, but the broken particles readily evacuate the surface leaving it rough and pitted. Other frangible particles such as sand, glass beads, crushed rock and the like, also may be used but will require more severe grinding of the roll surface to insure fairly complete removal from the surface.
Rollers used to modify painted surfaces while they are wet to form thereon a design have been found essentially of soft rubber preferably sponge covered by soft easily compressible material such as felt, flannel, wool and the like previously perforated to form a given design.
If more than one roller capable of providing the same design is needed care must be exercised in cutting up the fabric to insure regularity either in the size, position or configuration of the cutout portions.
Rollers also have been provided with separate resilient pads arranged in any given design along the circumference of the roller spottedly applying liquid to a surface.
SUMMARY OF THE INVENTION In accordance with the invention claimed a new and improved apparatus and method of manufacturing rollers is provided which makes it possible to repetitively reproduce a plurality of like rollers having predetermined surface configurations.
It is, therefore, one object of this invention to provide a new and useful apparatus for manufacturing rollers for decorative purposes having substantially the same surface configuration.
Another object of this invention is to provide a new and improved method of cutting the surfaces of rollers used in decorating devices.
A further object of this invention is to provide a new and improved apparatus for deforming the surfaces of soft porous rollers into given surface configurations repetitively and to be able by simple adjustments to change the surface designs of later handled rollers.
A still further object of this invention is to provide a new and improved apparatus for the forming of the surfaces of porous decorating or marking devices through the medium of which the decoration or marking ofa surface by liquid may be effected with ease and expedience.
A still further object of this invention is the production ofa decorating or marking device which is simple in construction, inexpensive in manufacture, and durable and efficient in use.
Further objects and advantages of the invention will become apparent as the following description proceeds and the features of novelty which characterizes this invention will be pointed out with particularity in the claims annexed to and forming part of this specification.
BRIEF DESCRIPTION OF THE DRAWING The present invention may be more readily described by reference to the accompanying drawing in which:
FIG. I is a side view partially broken away of an apparatus for forming the surface of a prefabricated roller with' a predetermined design and embodying the invention;
FIG. 2 is a cross-sectional view of FIG. I taken along the line 22;
FIG. 3 is a cross-sectional view of FIG. 1 taken along the line 3-3;
FIG. 4 is a cross-sectional view of FIG. 3 taken along the line 4-4; and
FIG. 5 isa modification of FIGS. 1-4 wherein a burning iron has been added to a template.
Referring more particularly to the drawing by characters of reference, FIG. I discloses a frame 10 having mounted on it a horizontal lower shelve 11 for supporting an electric motor 12 and a pair of horizontal crossarms I3 and 14 mounted above said shelf for supporting a rotatably mounted wire brush 15. Bush 15 is rotatably mounted in bushings l6 and 17 which are mounted on and clamped to crossarms 13 and 14. Brush 15 is rotated by motor 12 through a drive belt 18 interconnecting the axis 19 of motor 12 with the axis 20 of brush 15 through belt driven pulleys 21 and 22, respectively.
Brush 15 is so mounted that its outer periphery extends through an opening 24 in a top platform 25 mounted on the top ends of vertical upright members 26 forming a part of frame 10.
The opening 24 is covered by an varcuate shaped template 27 curved to fit the outer circumference of the brush and provided with a plurality of apertures 28 which are arranged in a predetermined design. As the wire brush is rotated the ends of the wires protrude into the apertures of the template and move across the outline of the apertures in the direction of rotation of the brush.
The template is fastened in place on the top 25 of the frame by clamp plates 29 and 30 one mounted on each side of opening 24. The template is provided with horizontally extending edges which are arranged to slide in slots 31 formed between clamp plates 29 and 30 and the top 25 of frame 10.
As noted, templates having different apertured designs may be readily substituted one for the other so as to produce rollers having different surface designs.
In order to move a plurality of rollers 32 one at a time over the template 27 in a uniform manner a feed conveyor 33 is attached to frame'l0. The conveyor, a chain link drive comprising crossmembers 34 attached to the chain across a drive shaft 35 and a driven shaft 36. Shafts 35 and 36 are interconnected by the chain link drive passing over sprockets 37 and 38, respectively.
The drive shaft 35 is rotated by an electric motor 40, mounted on one side of frame 10,through a chain drive 41 driving a shaft 42 through sprocket 43. A chain drive 44 connected to a'sprocket 45 on shaft 42 is connected to drive shaft 35 through a sprocket 46 (FIG. 2).
Shaft 42 has mounted thereon a belt drive 50 which is driven by shaft 42 and drives an endless belt 51 which passes over and around a driven belt drive 52.
The belt drive 52 comprising belt 51 is arranged to receive rollers 32 when they are moved to the end of the feed conveyor 33. The moving belt 51 grabs the rollers and rotates them as they are actuated along a path over the template 27.
As noted from FIGS. 1 and 4 of the drawing, the endless belt 51 squeezes the rollers, thereby reducing their diameters and causing the outer periphery of the roller to extend into apertures 28 in template 27. The endsof the wires ofthe wire brush l5 protruding through the apertures of the template cuts and removes from the roller the material extending into the apertures of the template. Thus, as the roller is caused to rotate across the template and particularly the apertures in the template the ends of the wire brush cut out given portion of the rollers surface. Since the distance across the template in the direction of rotation of the rollers is substantially equal to the circumference of the squeezed roller under the moving influence of belt 51 one rotation of the roller will occur while passing over the template. One rotation of the roller will cause the roller to be deformed along its total circumference according to the design configuration of the template.
The tension of the belt 51 controls the depth of the material removed from the roller. By decreasing the belt tension the rollers will be squeezed less and the depth of the cut of the material by the ends of the wires of brush 15 will be reduced.
To change the design configuration of the treated roller, the operator of the apparatus merely removes the template and replaces it with another of a different predetermined design configuration.
Although a wire brush has been shown to remove predetermined portions of the surface of a soft pliable roller it should be understood that other suitable means also may be used (FIG. 5) such as a burning iron. A burning iron 60 formed ofa suitable resistance connected across a source of electric power could be used individually or in combination with the templates as the need requires.
The roller 32 has been defined as being of a porous material which could be natural and synthetic rubber or any other suitable material that paint rollers and the like are now made out of. The roller surface should have a porous and roughened surface for use in the application of liquids to a plane surface.
Although but two embodiments of the present invention have been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.
