PAUL RISSMANN, OF DETROIT, MICHIGAN, ASSIGNOR TO FISHER BODY CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OFNEW YORK.

MACHINE FOR THE MANUFACTURE OF CLOTH COVERING- TUBES FOR AUTOMOBILE WINDOW SASH.

Application filed August 12,1920. Serial No. 403,043.

To all whom it may concern:

Be it known that 1, PAUL RISSMANN, a citizen of the United States, residing at Detroit, in the county of Wayne, and State of Michigan, have invented certain new and useful Improvements in a Machine for the Manufacture of Cloth Covering Tubes for Automobile Window Sash, of which the following is a specification.

This invention relates specifically to a machine for forming the covering for metal channels used to form the sash of an automobile closed body window.. Of course, the invention is of broader scope than the manufacture of the specific material referred to.

The broad invention may be said to be apparatus for making a piece of fabric tubing out of material folded upon itself and then secured together with an adhesive strip and further in a broad sense the butt-joining of two pieces of fabric. The particular features of the construction will be best understood when a detailed description is had of the apparatus.

In the drawings,

Fig. 1 is a side elevation of the machine.

Fig. 2 is a plan view of the machine.

Fig. 3 is an end elevation of the same taken from the right of Fig. 1. 1B Fig. 4 is a section on the line 44 of ig. -5 is a section on the line 5-5 of Fig. 2. FFig. 6 is a section on the line 6-6 of ne of the most common forms of window sash now used for automobile closed bodies is one that is formed by a metal channel and suitably covered usually with a felt cloth or equivalent fabric material (see patent to John T. Allmand No. 1,147,837 The present method of fastening this cloth to the channel strip is to form it into a tube of proper width, whip-stitching it together. This forms a tube into which the channel may be slid, together with the packing that has been glued to it (see patent to A. Gagnon No. 1,243,728, for description of how the felt packing can be applied). This packing is covered with glue or other adhesivebefore bein slid into the fabric tube. A form 7 mem er is then slipped-into the channel sive operation compared with an automatic operation but the results are not as good for the reason that the stitching cannot possibly be as regular as work done by the apparatus now about to be described.

a designates a bench on which a machine performing. the work outlined is fastened. The machine comprises a base I) attached by bolts 0 to the table 0:. e is a pulley wheel adapted to be driven by a belt and having a shaft f journaled in the bearing '9 rising from the base I). The spool it stores a roll of fabric ribbon while a narrower spool 11 stores a roll of tape impregnated with rubber or some other sticky or glue-like substance. This will be called an adhesive tape in the claims. j is a guide arranged to take a cloth or fabric ribbon, double it upon itself to form a strip or preliminary tube of half the width of the original fabric, with the meeting edges meeting at the center of the strip. This it accomplishes by the ,folded-over converging guide is shown in Fig. 2, and sections of which are shown in Figs. 4 and 5. Suspended above the cloth and supported uponthis guide j, is a centering guide Z for the adhesive tape Z. This centering tape guide m simply rests on the top n of the fabric ribbon guide, being soldered to the reinforcing strip 0 soldered to this top. Another centering guide for the adhesive tape is designated 19 and is also soldered to the top of the fabric ribbon guide where it turns the outside in. This guide may now be properly appreciated. The fabric is fed ofi from the spool flatwise into this guide. By examining Fig. 4, it will be seen that the guide almost immediately begins to turn the edge portions of the ribbon in or concave the ribbon. The edges of the guide then are completely turned over (the outside turns in) at is until they meet. A little partition 9 divides the turned-over edge portions of the ribbon, while the top 11. (that hasbeen turned from outside in) serves to divide the foldedthat is fed upon the heating roll u. This heating roll u has a hollow interior in which is suspended a ring 41 having gas jet orifices which form a burner for heating the interior of the heating roll u. This member is suspended within the roll by the pipe .w-

which supplies the mixture for combustion. It will be evident from this description that first the under. side of the preliminarily-prepared fabric tube is heated by being drawn over the concave heating iron 8. This heating is only an indirect or secondary one as on y heat first used on the heating roll it reaches the concave iron 8. This is all that is required to warm the preliminarilyformed tube on the under side. The preliminarily-formed tube is then reversedby the roll t, and the side that has the meeting ed es which are desired to be secured to the ru ber-impregnated tape is brought directly over the. relatively higher heated heating roll u. The rubber in the tape is thus caused to melt and soften. The heating roll then pinches the preliminarily-formed tube between itself and the pressure roll m. This forces some of the softened fluid-like rubber compound into the edge portions of the fabric Where they meet, thereby securely fastening the fabric edges to the impregnated tape and thereby firmly securing them to each other. The completed fabric tubing then passes on to the spool y, completing the same and making itready for use.

The heating roll is carried on a shaft 2 which is journaled in a yoke or support 1.

The pressure roll a: is always fixed and always rotating, being carried on the end of the pulley shaft f. As soon as the heating roll-u is pressed against the pressure roll a;

it starts the tape, fabric ribbon, and the com- I pleted tube moving in this way: the heating roll u being pressed against the pressure roll a: that is rotating, is also caused to rotate.

This ulls the reversing roll if from the posi- 7 tion s own in the dotted lines of Fig. 6 over against the heating roll, as shown in full lines in this figure. The ironing roll then serves to rotate the tape spool and the fabric ribbon spool simply by pulling the material off from these two spools. The shaft 2 is journaled'in the yoke 1, which is pivotally supported on the upstanding lugs 2 of the casting which forms the base b of the machine. Within. the space between the yoke legs is located a pulley wheel 3 fast to the shaft .2. This, through a belt or cord 4, drives the pulley wheel 5, which in turn drives the storage spool 3 The belt may slip enough to compensate for an otherwise differential peripheral speed of the spool y 'as it fills up.

As already indicated, the yoke 1, which journals the heating roll and is pivoted to the base at 6, may be drawn. down to bring the heating roll against the "pressure roll :10. The foot of the operator may be brought against the pedal 7 which connects through the draw rod 8 with the yoke 9 that has two aI'IIIQS 10 connected with opposite sides of the yo e.

Referring to Fig. 3, it will also be seen that the lugs 11 on the bed casting support an arm 12 which supports the guide 7'.

One side of the spoolsz' and k may he slipped off at any time to replace the tape or fabric ribbon by loosening the set screws 13 and 14.

It will be apparent that'in a broader sense the apparatus is a machine for joining in a butt-seam two pieces of fabric, and hence claims are directed to this.

What I claim is:

1. A machine for butt-joining fabric portions, comprising a guide having the capacity of directing and guiding the edges of the fabric portions to hold the same in abutting relation and also to guide an adhesive tape along the meeting edges, a heater, a pressure member, and means for directing and pulling the fabric and tape in adjacency to the heater and into the pressure member, which serves to force the adhesive tape upon the said adjoining edges of the fabric.

2. A machine for butt-joining fabric portions, having in combination, a guide for directing fabric pieces into abutment at their edges and also serving to guide a traveling adhesive tape upon the edge portions abut ting,- a heater, a pressure member, and means for pulling the tape and fabric in proximity to theheater and against the pressure member to press the adhesive tape against the edge portions of the. fabric to complete the same.

3. A machine for butt-joining fabric portions, having in combination, a guide for directing the edge portions of traveling fabric into abutting relation and at the same time guide a traveling adhesive'tape "alongside of the edge portions, a heating roll,

4.

A machine for butt-joining fabric edges, having in combination, aguide for directing the edge portions of traveling fabric to cause them to abut and also for guiding a' traveling adhesive tape along the edge portions of fabric, a heating roll journaled in a pivotally-hung support, a pressure roll, means by Which the operator may move the pivotal support for the heating roll to press the same against the pressure roll, and means for pullingthe fabric and tape over the heating roll and between the heating roll and pressure roll.

6. A machine for butt-joining fabric edges, having in combination, a guide for pressure roll and the directing fabric portions to cause the edges to abut and at the same time guiding a traveling adhesive tape alongside of the meeting edges, a heating iron, a heating roll having a greater heat than the first-mentioned heating iron, means for reversing the traveling fabric and tape that pass from the heating iron to the heating roll, means for pressing the tape and fabric edge portions together after having passed over the heating roll, and means for pulling the fabric and tape through the aforementioned instrumentalities.

' 7 A machine for butt-joining fabric edges, having in combination, a guide for directing traveling fabric to cause the edge portion to meet and at the same time guiding a traveling adhesive tape alongside of the edge portions, and a heating roll and heating iron above the heating roll, means for heating the ironing roll and giving the heating iron a secondary heat, areversing member for taking the fabric and tape as it leaves the heating iron and reversing the same as it passes on to the heating roll, means for pressing the adhesive tape to the fabric edge portions as it passes off the heating roll, and means for drawing the tape and fabric through the aforementioned instrumentalities.

' In testimony whereof I affix my signature.

PAUL RISSMANN.
