Application April 1, 1958, Serial No. 725,529

2 Claims. (Cl. 223-46) The present invention relates to apparatus for making bows, rosettes, pompous and like ornaments.

Heretofore, apparatus and machines have been developed for making bows and like ornaments and such apparatus and machines have either been able to only partially make the bows or if the machine completely forms the bow, the same is a very complex and bulky machine.

It is an object of this invention to provide a machine or bow making apparatus, which is a simple light weight and portable device readily usable by any inexperienced person or. even children, whereby a professionally per fect appearing ornamental bow may be producedby such inexperienced persons.

Another object is to provide a novel bow making apparatus adapted to produce in one bow forming operation a pompon bow, rosette or the like, having a plurality of bow loops of different colors.

Another object is to provide a novel ribbon spool support for pluralities of spools of ribbon of various colors,

in combination with guide means for feeding the ribbons in an untwisted and fiat position to a ribbon loop forming frame for operation thereon by an operatively associated notching cutter carried by the ribbon loop forming frame.

A further object is to provide a novel cutter means adapted to oppositely notch the intermedate strips or reach or reaches of ribbons looped on a ribbon loop forming frame, whereby the final ornamental bow or the like may be manually tied at the opposed notches to form the finished product.

Still another object is to provide a bow making device that is adjustable, to thereby make difierent sizes of ornamental bows and the like and also to provide means to maintain the bow ribbon under proper tension while the device is in use.

The foregoing objects of the present invention'are attained by providing a portable device for household use, which broadly includes a crank operated ribbon looping means, a remotely positioned ribbon spool support adapted to support a plurality of spools of ribbon in offset relation for paying out the ribbon separately from each spool, ribbon guide means adjacent the ribbon spool support and the ribbon looping means, positioned so the payed out ribbon feeds to the said looping means from the ribbon spools in a flat and untwisted position, and a ribbon notch cutter having V-shaped cutters arranged to form oppositely opposed notches in the opposite longitudinal edges of the reaches of the respective ribbon loops on the said looping means.

Other objects, advantages and uses of this invention will appear more fully after reading the following detailed description together with reference to the accompanying drawing wherein one embodiment is illustrated.

In the drawings:

Figure 3 is an end view of the apparatus looking in the direction of the arrow ingFigure 2; and

Figure 4 is a plan view of one strip or reach of a ribbon loop shown with the opposed tie notches formed therein by the novel cutter mechanism.

Ribbon spool support means Referring in detail to the drawing and first with particular reference to Figures 1, 2 and 3, there is disclosed a rectangular base or block 10. This base supports a spool support bracket 11 formed with a laterally extended foot 12 formed with fastener openings 13, 14 and 15 positioned in triangular relation for receiving fasteners, such as bolts or screws 16, see Fig. 3, to thereby mount the spool support in a vertical position from the base adjacent an end and a longitudinal edge thereof.

The bracket 11 is formed of a single flat bar and is formed with an angularly oifset upper portion A which mounts a spool' spindle '17 extending laterally adjacent the end thereof and alower portion B extending from the'foot 12 formed therein. The portion B likewise mounts a spool spindle 18. These spindles are formed with beads 19 and 20 respectively and may be threaded on one end and the portions A and B may be formed with threaded apertures 21 and 22 respectively, so the spindles maybe threadedly attached and detached with a ribbon spool 25 and 26 respectively thereon.

. As. shown in'Figure 2', the offset arrangement of portions A and B of the spool support permits very eflicient unwinding and pay out of a plurality of ribbons 23 and 24 from their respective ribbon spools 25 and 26 to a common guide roller 27. The guide roller 27 is rotatably mounted in a U-bracket 28 having oppositely apertured side lugs 29 and 30 for receiving the roller spindles 31 and 32. Preferably the guide roller U- bracket is secured to the base 10 in a corner thereof by countersunk screws 33 and 34 and positioned, so as to reeve the ribbons in a straight tangential line from the respective ribbon spools to thereby prevent twisting and to maintain the ribbon flat and uncurled at the edges 35 and'36 thereof. This condition of the ribbon facilitates the notch cutting operation hereinafter described in con nection with Figure 4. Also, the guide roller brackets may be made adjustable to provide for ribbon of differ ent widths.

Ribbon guide means The ribbons 23 and 24 are reeved over and under the guide roller 27 in a straight line, see Figure 2, to a second guide roller 37 mounted in a U-bracket 38 similar to U-bracket 28, positioned on the same side of base 10 in the opposite corner from roller bracket 28, and having similar apertured lugs 39 and 40 for rotatably receiving spindles 41 and 42 of the roller 37. The reaches or strips of ribbon 23 and 24 are held taut by a tension means, such as the leaf spring 43, which prevents any back slack from the guide roller 37, as it leads off to the ribbon loop forming means C and the ribbon notching cutter D, now to be described.

Ribbon looping means and notch cutter The combination ribbon looping means C and ribbon notch cutter means D are supported above the base 10 by a vertical support post 44 having a circular base 45 apertured radially to receive fastener elements, such as screws or bolts 46 to anchor the same firmly to the base 10. The upper end of the post 44 is bored through transversely and enlarged to provide a bearing 47 for journalling a crankshaft 48, see Figure 3. The post is mounted adjacent the corner edge of the base at the opposite side of the block 10 from the ribbon feeding mechanism. This position of 'the post is desirable to provide for the extension of the crankshaft 48 from the bearing 47 and to properly position the ribbonlooping frame C and the cutter D with respect to the ribbon guide roller 37. v p

The crankshaft 48 extends from one side of the bearing 47 beyond a longitudinal side of the base 10 in the form of a hand crank 49 and from thepther side of the bearing the crankshaft extends over the base 10 to a position adjacent one edge of the ribbon on the looping frame C. This end of the crankshaft'is formed with a T-head 50 having reduced ends or pivot studs 51 and 52 on which are pivoted the ends of spaced pairs of arms 53-54 and 55-56, each pair of arms being secured to plates 57 and 58, respectively. The plates form the major parts of a ribbon dual notch cutter. For example, plate 57 carries a pair of oppositely positioned V-shaped cutter elements, and plate 58 serves as the anvil plate of the cutter, which plates when squeezed together over a strip of ribbon cut opposed notches 59 and 60 in opposite longitudinal edges 35 and 36 of the ribbon strip, see Figure 4.

The ribbon looping means C comprises a cross bar 61 secured intermediate its ends at 62 to the crankshaft 48. This bar 61 is positioned on the crankshaft rearwardly of the cutter D. Slidably adjustable from each end of the cross bar 61. are bushings 63 and 64, respectively, With set screws 65 and 66 to hold the same to adjusted positions. Projecting in spaced substantially parallel relation from the bushings are arms 67 and 68 each formed with slotted ends 69 and 70 for receiving the longitudinal edges of ribbon or ribbons to be looped around the arms when the ribbon looping frame is revolved by the crankshaft as hereinafter described under the heading, Operation.

Operation To operate the apparatus, the machine is loaded by placing one or two spools of ribbon on spindles 17 and 18. It will operate 'with one or two spools of ribbon and they can be of different colors. The ribbon passes under the guides 27 and 37 and is inserted in a slot in either of the winding arms 67 and 68. The winding arms 67 and 68 are adjustable for making bows of different lengths. The handle 49 is then rotated clockwise which wraps the ribbon around the winding arms 67 and 68 to any desired thickness, depending on the fullness of bow desired. The cutting plates 57 and 58 are then brought together with the left hand and the opposite edges of the ribbon are notched as shown in Fig. 4. Arrows show the path in which the cutter plates travel to notch the ribbon.

It is then tied with a much narrower ribbon across the V-notch and cut. Leaf spring 43 retains the ribbon during the final tying.

Remove the tied ribbon from winding arms 67 and 68 and by inserting ends of cut ribbon in slot 69, another bow is ready to be formed.

Without further description, it is believed the invention has been fully illustrated and described so that others may-understand and practice the invention in accordance with the Patent Statutes. It is to be understood, however that this invention is an example only of the apparatus and other arrangements and improvements may be made without departing from the scope of the present invention.
