.10 Claims.

This invention relates to decorative ornaments. More particularly, my invention relates to decorative ornaments of the convoluted type adapted for making i'estoons, streamers and a other similar decorative articles.

One of the objects of my invention is to provide an improved method for making convoluted decorative ornaments of the character described and in which'the resulting ornaments thus proiil duced will be prevented from axial displacement and distortion. 1

Another object of my invention is to provide an improved decorative ornament of the character described which shall comprise relatively w few and simple parts, which shall be relatively inexpensive to manufacture, which shall be sturdy in construction, neat in appearance and at the same time highly eflective for the purposes intended.

as A further object of my invention is to provide an improved method for making decorative ornaments of the character described, which shall be relatively easy to practice, which shall com= prise relatively few and simple steps, and which 25 at the same time shall be relatively inexpensive and highly eflicient. I

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the feaao tures of construction, combinations of elements,

and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the claims.

35 In the accompanying drawing, in which is shown one of the various possible embodiments of this invention;

Fig. l is a side elevational view, largely diagrammatic, of an apparatus illustrating my im- 40 proved method of manufacturing decorative ornaments,

Fig. 2 is a plan view, slightly in perspective,-

of a fiat strip of material used in my improved method of making decorative ornaments,

45 Fig. 3 is a view similar to Fig. 2, but illustrat finished convoluted decorative article made in accordance with my method,

Fig. 8 is a cross-sectional view taken substantially on the line 8-8 of Fig. '7; and

Fig. 9 is a cross-sectional view taken substantially on the, line 9-9 of Fig. 1.

Referring now in detail to the drawing, there is schematically disclosed the various steps employed in my improved method for manufacturing a convoluted decorative article of the character described, from flat strips of paper, Cellophane or any other similar suitable resilient material. My improved method of manufacture will now be described.

A flat strip ill of any suitablematerial customarily employed for making convoluted ornaments, such as paper, Cellophane, or the like, shown in Fig. 2 of the drawing, may be first crimped or pleated inany suitable manner well known for crimping or pleating fiat strips, to produce a crimped, crinkled or pleated strip H, as shown in Fig. 3. The nextstep in my method comprises the positioning of a core member [2 and a core member l3 on opposite sides of the strip! I. The core members I2 and I3 are preferably positioned along the longitudinal axis of the strip ii and are in alignment with each other. These core members may be of any suitable core material, such as for example, heavy wire, light wire, cord, thread, or any combinabeen properly positioned, as shown in Figs. 4 and 5, the strip i I together with the cores I2 and It are axially twisted to form a convoluted ornament, as shown in Fig. 6. It is understood that any desired amount of twisting may be employed to obtain the result desired. If the ar ticle illustrated in Fig. 6 is iurther axially twisted, a convoluted article such as shown in Figs. 7 and 8 may be produced in which the convolutions are generally circular in cross-sectional contour, as shown in Fig. 8, and in which the said convolutions are relatively closely adjacent. It is also noted from Figs. Band '7 of the drawing that the cores l2 and. iii are so twisted as to hold the spaced convolutions I in definite spaced relationship and to prevent longitudinal extension or contraction of the decorative ornament. It is thus seen that there is provided a convoluted form at all times without the necessity of employing adhesive materials heretofore used in the manufacture of similar ornaments.

While in Fig. 3 of the drawing I have shown the strip III as crimped, or pleated, it is undertion thereof. After the cores I2 and I3 have stood that my improved method may be satisfactorily practiced and my convoluted ornament produced without crimping or pleating the In Figs. 1 and 9 of the drawing there is diagrammatically shown an arrangement of one form of apparatus for automatically manufacturing a' convoluted decorative ornament in accordance with my invention. The said apparatus may comprise a roll it of fiat flexible paper material, similar to .the material Iii, which is rotatably mounted on a suitably supported shaft l1. There is also provided a pair of spools I3 and I9. rotatably mounted on suitably supported shafts 20 and 2|. The spools i3 and I8 may contain the material for the core members l2 and it. The core material from the spools l3 and iii are fed between a pair of suitably mounted adjustable tension rollers 22 and 23, each of said rollers 22 and 23 having a circumferential groove 22a and 23a, respectively, into which the core material from the spools i 8 and it are adapted to be received. The spools l3 and I3 are so positioned with respect to the rollers 22 and 23 as to provide a space between the cores l2 and II to permit the feeding of the strip Iii between the rollers 22 and 23 in such manner so that one core, such as core l2, will be positioned adjacent one side of the strip l0 and the other core. i3, will be positioned on the opposite side of the strip l0. substantially along the longitudinal axis of said strip, as the strip l0 and cores l2 and I3 are passed between the rollers.

Any suitable means may be provided for causing the cores l2 and I3 together with the strip III, to be unwound from the spools l8 and I8 and the roll it and passed between the rollers 22 and 23. Such means may comprise an elongated threaded shaft 25 provided with a key-way 23. The shaft 25 may be journaled at one end thereof in a fixed bracket 21. In the said bracket 21 there is also fixedly supported a rod member 23 disposed at a spaced distance from the shaft 23 and parallel thereto. A member 33 supported on the shaft 25 and rod 23, is adapted to slide adjacent one end thereof on the shaft 23 and is provided at the other end thereof with a. threaded opening into which the correspondingly threaded shaft 25 is received. It is thus seen that upon rotation of the shaft 25 the member will be caused to move due to the threaded opening above described and will freely slide on the'shaft 23. Any suitable well known means (not shown) may be employed for causing rotation of the shaft 25. Rotatably mounted on the member so is a shaft 32, to the end of which the ends of the cores i2 and I3 are fixedly attached. It is thus seen from the above described construction that when the shaft 25 is rotated so as to cause the member 30 to move in the direction of the arrow A the cores l2 and 13 will be unwound from the spools l3 and I9, and passed between the tension rollers 22 and 23, as hereinbefore described.

Means are provided for twisting the cores l2 and I3 as they emerge through the rollers 22 and 23 so that the material It, which is simultaneously fed between the cores i2 and I3 may be also twisted to form a convoluted ornament as shown .in Figs. 6, 7 and 8. Any suitable means maybe f the shaft 25. Mounted on the shaft 32 for rotation therewith is a pulley 40. The pulley 35 is caused to drive the pulley by means of an interconnected belt 33. It is thus seen that when the shaft 25 is .rotated so as to cause the member 30 to travel in the direction of the arrow A to exert a pulling force on the cores l2 and I3, the pulley 35 will be caused to rotate with the shaft 25 due to the key, 31 being engaged in the keyway 38 and at the same time being free to slidably move with the member 30. The rotation of the pulley 35 will cause the pulley 43 and the shaft 32 to rotate by means of the belt 38. Therefore, it is seen that as the member 30 is being slidably moved in the direction of the arrow A to exert a pulling force on the cores I2 and I3, at the same time the said cores l2 and I3 will be axially twisted due to the rotation of the pulley 4t and shaft 32.

In view of the above description, it is seen that as the strip I0 is fed between the cores l2 and I3 it frictionally passes between the rollers 22 and 23 and immediately upon emerging from said rollers 22 and 23 it is twisted with the cores I 2 and I3 to form a convoluted ornament on the nature of that shown in Figs. 6, 7 and 8. If desired, the rollers 22 and 23 may have their surfaces corrugated on opposite sides of the grooves 22a and 23a so that the strip ill will be corrugated or crimped as it passes between the rollers and before it is twisted with the cores l2 and I3.

While, in Figs. 1 and 9 of the drawing, I have shown one'form of apparatus for practicing my improved method for manufacturing convoluted ornaments of the character described, it is understood that any other suitable apparatus may be employed for feeding a strip of material between two cores and thereafter twisting the cores and paper.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possibleembodiments might be made of the above inven on, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
