Y.

Original application December 9, 1937, Serial No.

Divided and this application April 23, 1938, Serial No. 203,893. Renewed October Claims.

My invention relates to processes for ornamenting leather and fabrics and other such materials generally used in making shoes, belts, bags, and many other articles of merchandise and this application is a division of application filed by Rene M. Sichere for Machines for ornamenting leather, etc., filed December 9, 1937, Serial No. 178,980.

The object of my invention is to provide a process for applying colored matter to the material in a line or stripe form and to indent the material at one or both sides of the stripe to simulate stitching, or to simultaneously stitch a line or lines adjacent the stripe as it is formed, or indented.

The finished product closely resembles a ribbon sewed on the leather or fabric when the stripe is made of sufficient width, and the cost of manufacture is far less than that required to use a ribbon overlay.

In order to carry out my process at a low cost I have designed a machine which may be employed in the operation of ornamenting materials, and the process and machine used in the process is herein described.

Referring to the drawing forming a part of the specification:

Fig. 1 is a perspective View of the machine.

Fig. 2 is a front elevational view of the machine.

Fig. 3 is a side elevational view, shown partly in section.

I0 indicates a presser-foot which is carried by an integral shank II which extends upwardly therefrom and serves as a support for the mechanism.

The shank is formed to provide a rectangular shaped opening I2 the side walls of which serve to guide the casing in a vertical direction.

The casing is made in two half parts indicated by I3 and I3, the portion I3 having an integral lug I4 which extends into the opening I 2 and fits in sliding engagement with the side walls thereof and is held to the shank II by the bolt and nut construction I5.

The casing portions are held together by screws I6 and I1 respectively, the portion I 3' remaining in position when said screws together with the bolt 20 are removed.

The casing portions are formed to provide a slot I8 of circular form between them in which a wheel I9 fits in close sliding contact at its sides, with its lower side I9 normally extending thru the slot I0 and resting in alignment with or slightly. below the lower side of the casing and in alignment with or slightly below the lower side of the presser-bar or foot when the presser-bar is used.

The wheel is carried by a shaft 20 on which it is rotated and the shaft is provided with a screw adjacent the head 20' which screws into a thread (not shown) formed in the casing portion I3 and serves to assist in holding the casing portions together, as will be readily understood.

The outer or tread surface 2! of the wheel I9 is roughened or serrulated in any desired form to carry and deposit a color or design on a surface such as leather, to simulate a ribbon, tape or cord, etc. and to serve as a means whereby the wheel may be rotated by passing the material in contact therewith in the act of applying .the coloring matter thereto.

The upper end of the casing is formed to provide a cylindrical part 22 which is open at its upper and lower ends and serves to support a removable container 23 which holds the coloring matter.

The container is provided with oppositely extending pins which fit in bayonet shaped slots 25 formed in the enlarged top portion 26 of the easing as illustrated.

This arrangement prevents the displacement of the container when the machine is in operation and also serves to position the lower end thereof adjacent the Wheel I9.

To open the container, which is made of soft material, a screw 2! formed with a sharp edge on its inner end, is fitted to screw into the casing wall and extend therethru into contact with the lower end of the container at one side thereof and shear a portion to permit the coloring matter to fiow to the tread of the wheel forward of its greatest diameter so that the color will fiow in the direction in which the wheel is rotating.

Formed in each of the inner side portions of the casing is a shallow groove indicated by 28 which extends in curved form from the forward side of the wheel to a container 29 and serve to collect and carry excess liquid which may leak from the tread of the wheel, to said container.

Located above the grooves 28 are grooves 30 which lead from the wheel at 3| to said container and serve the same purpose.

34 indicates a vertically extending shaft which extends thru the upper Wall of the casing at their point of juncture and carries a frustoconical brush 36 which rests in a chamber 35 and is rotated by means (not shown) which may be automatically driven when the device is operating, or may be manually rotated, the object being t f2 keep the serrations free from dry matter or from clogging.

32 indicates a piece of material such as soft.

rubber, which fits in a slot 33 formed in the casing, and which serves to closely confine the coloring matter in the serrations in the wheel.

The presser-foot ID is provided with two or more apertures 36 spaced apart, thru which needles may pass to puncture or stitch the leather or material being treated, or to indent it, to. simulate stitching, the band or stripe as it is formed, and a band of colored material similar to a type-writer ribbon may be used to carry the color into the indents, said ribbon being indicated by 31 in Fig. 3.

The cross-head 38 carrying the needles may be reciprocated in timed relation with the movement of the material being treated, the sewing machine serving the purpose in the usual manner of stitching, and the eyes of the needles serving to carry the color into the perforations or indents.

The container 29 is used as a drip-pan and may be removed at any time by sliding it from its position of rest.

39 indicates a spring which normally holds the casing in its lowest position but permits it to rise a limited distance in case the wheel should encounter a hard unyielding substance or that the thickness of the material should vary, thus permitting the machine to follow any uneven surface over which the wheel is passing.

The device may be operated by means of the sewing machine to which it may be attached, and which serves to feed the material to the tread of the wheel automatically and at the same time to indent the surface of the material or puncture same with the needles, as will be readily understood.

The process of simulating a ribbon by depositing a band or line of coloring matter on a surface of leather and simultaneously simulating a line or lines of stitching along the margin or margins of the band, may be carried out by a machine differing in construction from that shown in the drawing, the present machine being shown and described to illustrate the process and means by which it may be commercially used.

Having thus described my invention I claim as new:

1. The process of ornamenting leather or fabric and which extends along,

material consisting in continuously feeding and simultaneously applying to the surface thereof a stripe of coloring matter and indenting the material in juxtaposition to the side edges of the stripe to simulate lines of stitching.

2. In methods of ornamenting leather and similar sheet materials, that improvement which comprises in continuously feeding and simultaneously applying an ornamental stripe of fluid coloring matter to the surface of the material being treated and forming a plurality of spaced perforations along opposite sides of the stripe in juxtaposition thereto to simulate a stitched-on overlay stripping.

3. In methods of ornamenting leather and similar sheet material, that improvement which consists in continuously feeding and simultaneously applying an ornamental stripe of fluid coloring material thereto and forming a plurality of equally spaced indents in the sheet material in juxtaposition to the side edges of the stripeto simulate a stitched-n overlay stripping.

4. In a machine for ornamenting material, such as leather or fabric, wherein the material is fed through the machine during ornamentation thereof, a presser foot and carrying shank therefor, a reciprocating head on the machine, a pair of needles carried by the head for forming parallel rows of perforations in the material in simu' lation of lines of stitching and means carried by the presser foot between the presser foot shank and needles for applying a colored stripe to the material between the lines of perforations in the material.

5. In a machine for ornamenting material, such as leather or fabric, wherein the material is fed through the machine during ornamentation thereof, a presser foot and carrying shank therefor, a reciprocating head on the machine, a pair of needles carried by the head for forming parallelrows of perforations in the material in simulation of lines of stitching and means carried by the presser foot between the presser foot shank and needles for applying a colored stripe to the material between the lines of perforations 'in the material and means associated with the presser foot for applying coloring matter to the needles as they pass through the material to color the walls of the perforations.
