PRODUCTION OF RIBBON BOW Filed June 25, 1941 B Spet-She'et'Z Patented Apr. 27, 1943 UNITED STATES ?ATEh -T OFFIE 6' Claims.

This invention relates to the production of ribbon bows, which is to say a bow composed of several connected ribbons of rayon, satin or other like or suitable material. Stated more particularly, the bow to which the present invention pertains is of that character heretofore produced by hand and which is most general-1y applied as a decorative touch to the boxes used as containers for hats, dresses, candy and the like, comprising a severalty of ribbons, usually three, of which each is given a similar bias cut forming a rhomboidal figure. In forming the bow from these rhornboidal strips, each is given a longitudinal folding intermediate the ends to-produce a pleated effect, and the strips are then compacted together with their pleated parts in sideby-side relation, whereupon a narrow tie-ribbon. is passed about the contiguous centers, much in' the manner of the fleur-de-lis. The open flowering effect is obtained by spreading the petalforming tips or, otherwise stated, pulling the side edges laterally one from the other.

The object of the present invention is to provide a new method of making such a bow, and the equipment for practicing the method, permitting the said ribbon bows to be produced with appreciably greater facility, and uniformity, than has been heretofore possible.

The invention consists in the new method and in the novel construction, adaptation and combination of parts of a machine therefor, as will be hereinafter described and claimed.

In the drawings:

Figure l is a side elevation, with parts broken away and shown in longitudinal vertical section on the line li of Fig. 3, representing a machine suitable for producing the bows in accordance with the present invention.

Fig. 2 is a similar but fragmentary view indicating the parts in their operating as distinguished from the inoperative positions shown in Fig. 1.

Fig. 3 is a transverse vertical section on line 3-3 of Fig. 1 excepting that one of the ribbon strips is shown in position preparatory to being folded by the creasing jaws of the machine.

Fig. 4 is a View likewise showing the ribbon strip and taken to an enlarged scale on line 4-4 of Fig. 2.

Fig. 5 is a top plan View showing one of the ribbon strips to a scale enlarged from that of the preceding views, the strip being illustrated as the same is applied on the forming table preparatory to being creased by the creasing jaws shown by dotted lines.

Fig. 6 is a top plan view indicating the manner in which the creased ribbons are transfixed successively upon a skewering pin to hold the creases preliminary to a tying of the bow; and

Fig. 7 is a top plan View of the finished bow.

Having reference to said drawings, the numeral 8 indicates a bed plate on which is mounted a bifurcated forming table H] of which the bifurcation interrupts a relatively flat working surface and operates to receive the lower of two. complementary jaws H and i2 movable in unison and in a common vertical plane out of and into juxtaposition onthe substantial horizontal plane of said working face of the table. Projecting upwardly from the bed plate in spaced relation to the rear of the forming table is a forked standard l3 operating as a journal bearing for a pivot pin M, and fulcrumed about such pin are lever arms [5 and It for the jaws. I'I designates a foot-operated treadle connected by rods l5 and It to the lever arms for closing the jaws in opposition to a spring [3, and 2:! denotes a treadle-stop for limiting the opening movement of the jaws.

Said jaws, which desirably are removable from the supporting lever arms, have their meeting faces serrated to provide series of transversely disposed teeth ii and I2 arranged to inter-fit when the jaws are in juxtaposition, and are further characterized in that a channel, as 2| and 22, is carried longitudinally in traversing relation through each series of teeth. It is the function of these channels, which lie on the median line of the jaws and register in the closed positions of the latter, to form a bore extending the length of the jaws and which accommodates the travel of a skewering pin 23 movable with a supporting hasp 24 in a slide bearing formed by a bracket extension 25 of the bed plate. On the outer end of the hasp is a cap piece 24 arranged to be engaged by the palm of the operators hand for advancing the pin through said bore in opposition to a spring 2%. 2'! indicates a stop-collar for limiting the spring-influenced retractive movement of the pin, and 28 indicates a needle screw working in a groove in the hasp to hold the pin against rotation.

Describing now the production of the bows, for which I employ, desirably, strips of rayon cut on the bias to the shape of a rhomboid as indicated in Fig. 5 and which I will hereinafter refer to as a ribbon leaf, it will be seen that I apply such leaf to the working surface of the table top and between the open jaws of the lever arms such that a rectilineal line projected between the extreme tips of the leaf lies centrally of and in approximate paralleling relation to the creasing teeth of the jaws. While not indicated in the drawings guide lines for this purpose are etched in the table top. With the ribbon leaf so disposed, the operator closes the jaws through the instrumentality of the treadle (Figs. 2 and 4) whereupon the material is creased between the interfitting teeth. This creased leaf is then transfixed by the skewering pin, the treadle released to open the jaws, and the spring 26 allowed to assert its power in retracting the skewering pin, with the creased leaf thereon, from the forming table. The operation is repeated with two other ribbon leaves (Fig. 6), following which the operator compacts the transfixed centers together and ties the same by passing a narrow ribbon, or other suitable means, over one side edge of the pin, under the ribbon leaves, and upwardly over the opposite side edge of the pin, the two free ends being caught above the assembly. The tied leaves are then slid off of the skewering pin, and the tips spread outwardly as indicated in Fig. 7 to form the petals of the finished bow.

It may be here stated that the teeth of the jaws are in practice given a slight rounding in order thereby to preclude any possibility of cutting through a thread or threads of the ribbon leaf.

Numerous departures from the embodiment illustrated in the drawings will readily suggest themselves, and in connection therewith it may be pointed out that I have employed gears in lieu of the jaws to perform the creasing function, and have applied cam-operation to the jaws for automatic functioning of the same as a step preliminary to the development of an automatic feed for the ribbon leaves. stapling, rather than manually tying, the ribbon leaves as the same are transfixed by the skewering pin is an obvious method step in acceleratin the production of the bows, and lends itself to a machine for performing automatically the manual steps which I disclose. Having cognizance of these as well as other modifications, ii; is my intention that no limitations be implied excepting as the same are necessarily introduced to the following claims to distinguish the present invention from previous knowledge in the art.

What I claim, is:

l. The method in the production of ribbon bows consisting in forming folds in complementary ribbon leaves by subjecting first one and then the other leaves of the bow to theplaiting action of interfitting teeth; transfixing the plaits with a skewering pin while held between the teeth; bringing the transfixed leaves into close compass on the skewering pin; and tying the plaits of the several leaves together while transfixed by the pin.

2. The method in the production of a ribbon bow which consists in forming a fold in a ribbon leaf therefor by subjecting the leaf to the plaiting action of interfitting teeth; transfixing the plaits with a skewering pin while held between the teeth; compacting the transfixed plaits on the pin and, coincident therewith, passing a tie about the plaits.

3. The method in the production of a ribbon bow which consists in creasing a ribbon leaf 1ongitudinally at uniformly spaced intervals, and folding the leaf upon the crease lines; transfixing the leaf to hold the folds by passing a skewering pin transversely through the plaits; and tying the plaits in contiguity While transfixed by the pin.

4. As method steps in the production of a ribbon bow, the act of creasing complementary ribbon leaves to produce fold lines, folding the leaves on the fold lines; while folded transfixing the leaves successively by passing a single skewering pin transversely through the folds; and fastening the several leaves together with the plaits in folded relation while transfixed by the pin.

5. As method steps in the production of a ribbon bow, folding a ribbon leaf; transfixing the folded leaf by passing a, skewering pin transversely through the folds; and fastening the plaits in their folded relation while transfixed by the pin.

6. The method of producing a ribbon bow consistin in folding a ribbon leaf; transfixing the plaits of the leaf with a skewering pin to hold the plaits; withdrawing the skewering pin with the transfixed leaf thereon from the plaiting scene; repeating to multiply the plaited leaves transfixed by the skewering pin; and compacting the transfixed plaits of the several leaves together upon the pin, and fastening the same in their compacted relation.
