Description: BOW FORMING DEVICE BACKGROUND OF THE INVENTION FIELD OF THE INVENTION This invention relates to a device for forming bows from a ribbon which includes a base plate and a pair of uprights mounted on the base plate. One of the uprights is resiliently biased toward the other upright for grippingly engaging portions of the ribbon inserted therebetweeh to hold bow loops formed from the ribbon in place while forming the bow. A tie wire is placed between the uprights for securing the portions of the bow loops retained between the uprights before removing the assembled bow loops. The uprights have opposed narrow edges to effectively grip the ribbon positioned therebetween. In one embodiment of the invention, the uprights include spaced upright plates to receive the tie wire and a forming arm which moves the portions of the bow loops between the uprights toward the base plate. DESCRIPTION OF THE PRIOR ART The formation of bows from ribbon for use on packages and other decorative uses is well known. It is also well known that it is guite difficult to form a ribbon bow with a plurality of loops by merely holding the intersecting cross over portions of the loop between the thumb and fingers when forming a bow. In view of long existing difficulties in forming bows by holding the assembled bow in one hand while the loops are formed with the other, devices have been developed to assist in forming a bow. The following U.S. patents disclose structures for this purpose: 2,542,222 2,763,080 3,816,888 4,454,968 5,356,056 The above patents include pegs or dowels which extend upwardly from a base plate in spaced relation on which bow loops are formed. In some of the patents, the base plate includes an upwardly extended pointed member which penetrates the overlapping, intersecting portions of the bow loop. In other of the patents, the bow is formed by forming loops around a plurality of adjacent pegs or dowels. Another device for forming bows haε been marketed under the trademark "Easy Bow Maker" manufactured by E-Z BOWZ, Inc. of Sevierville, TN. This device is a base plate with a pair of spaced dowels or pegs mounted rigidly thereon with the dowels receiving the overlapping, intersecting portions of the bow loops therebetween to hold the loops in assembled relation until they can be removed and secured by a wire wrapped around the intersecting portions of the loops to secure the bow in assembled relation. In some instances, distance indicating indicia may be provided on the base plate to facilitate the formation of bow loops of different lengths in order to form bows having various configurations. While the prior art discloses various devices to assist in the formation of bows from various types of ribbon, the prior art does not disclose a bow forming device that iε structurally or functionally equivalent to this invention. SUMMARY OF THE INVENTION An object of the present invention is to provide a bow forming device to asεiεt in the formation of variouε typeε of bowε in the form of a baεe plate having a pair of uprightε mounted thereon with at least one of the uprights being laterally moveable in relation to the other and spring biased toward the other to grippingly engage intersecting or cross over overlapping portions of the bow loops to retain the bow loops in assembled relation while being formed and enabling the intersecting cross over overlapping portions of the bows to be secured in assembled relation prior to removal from the bow forming device. Another object of the invention is to provide a bow forming device in accordance with the preceding object in which the spring biased movement of one of the uprights assures that the gripping surfaces of the uprights which engage the intersecting cross over overlapping portions of the bows remain in parallel relation to grippingly engage each intersecting, cross over overlapping portion of the bows with εubstantially equal gripping presεure. A further object of the invention iε to provide a bow forming device in accordance with the preceding objectε in which the gripping or engaging surfaces of the uprights are bevelled or tapered to form generally a narrow or knife edge gripping contact with the overlapping portions of the bows. Still another object of the invention is to provide a bow forming device in which the uprights are in the form of a pair of vertically extending, spaced plates to receive a forming arm therebetween with the forming arm being moveable downwardly in the space between the plates on each upright to engage and move downwardly the intersecting croεε over overlapping portions of the loops during asεembly of the bow. A still further object of the invention iε to provide a pivotal mounting for the forming arm to enable the forming arm to pivot in a vertical plane when moving downwardly in the space between the upright plates. Yet another object of the invention is to provide a bow forming device in accordance with the preceding object in which the pivotal support of the forming arm includes a structure to enable the forming arm to be detached and inserted horizontally in the εpace between the upright plateε in order for the forming arm to be moved vertically downwardly to engage and move the intersecting cross over overlapping portions of the bow loops downwardly to facilitate assembly of bow loops formed from relatively wide ribbon. Another significant object of the invention is to provide a bow forming device including a base plate with a pair of spaced uprights with one of the uprights being slidingly mounted on the base plate and spring biased towards the other upright by a pair of compression coil εpringε with the uprightε being in the form of pegs having facing gripping edges defined by bevelled or inclined edge portionε. Theεe together with other objectε and advantageε which will become εubεequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

DESCRIPTION OF THE DISCLOSED EMBODIMENTS The bow forming device illuεtrated in Figureε 1-5 iε deεignated by reference numeral 20 and includeε a generally rectangular baεe plate 22 having a pair of uprightε 24 and 26 mounted therein in oppoεed relation and a forming arm generally deεignated by reference numeral 28 pivotally supported from the base plate 22 in alignment with and for cooperation with the uprightε aε εet forth in detail hereinafter. The baεe plate 22 includes a dovetail groove 30 in the upper surface thereof which extends from edge to edge of the base plate. Each upright 24 and 26 includes an upright base 32 having inclined side edges 36 cooperating with the dovetail groove 30 to enable the upright bases 32 to be moved into the groove 30 by an endwise sliding movement. Rigidly affixed thereto or unitary with the upright base 32 is a pair of spaced upright plates 38 which are generally rectangular and parallel to each other with the upright plates 38 being spaced apart to define a slot 40 having an open upper end 42 and open side edges 44. The upright plates 38 are parallel to each other and perpendicular to the upright base 32 on each of the uprights 24 and 26. The εide edges of the upright plates 38 which are diεpoεed in opposed, aligned relation are chamfered at 46 by beveling or rounding the edgeε from the outer surface toward the inner surface as illustrated in Figure 2 to form a narrow or knife edge 48 on the opposed edges of the upright plates 38 on the uprights 24 and 26 respectively. The upper end of each of the opposed facing edges of the upright plates 38 are rounded or radiused as at 50 to facilitate the insertion of ribbon 52 between the uprights 24 and 26 in a manner described hereinafter. The upright 26 is stationary while the upright 24 is spring biased towards the upright 26. Spring biasing of the upright 24 iε provided by a pair of small compreεεion springs 54 received in socket 56 in an inner edge of an end plate 58 which haε inclined side edges slidable into the dovetail groove 30 and detachably secured thereto by screws 60 or other fasteners to enable removal of the end plate 58 for replacement of the springs 54 and for assembly and disasεembly of the uprightε in relation to the base plate. As illustrated in Figures 2 and 4, the springs 54 are relatively short to enable limited resilient movement of the upright 24 away from the upright 26 with the springs 54 normally biasing the upright plateε 38 on the upright 24 into engagement with the upright plates 38 on the upright 26 but enabling movement of the upright 24 away from the upright 26 when a ribbon 52 iε forced downwardly between the chamfered edges 46 on the plates 38 on the uprights 24 and 26. Movement of the upright 24 is guided by the upright base 32 engaging the dovetail groove 30 which will maintain the chamfered edges 46 of the upright plates 38 on the upright 24 parallel to the chamfered edges 46 on the upright plates 38 on the upright 26. Thiε εtructure effectively grips the intersecting, crosε over overlapping portions 62 of the ribbon when forming bow loopε 64. The forming arm 28 includeε a mounting plate 66 for the arm which includeε inclined edgeε for assembly with the dovetail groove 30. Projecting upwardly from the mounting plate 66 for the arm is a pair of spaced plates or lugs 68. The forming arm 28 includes an elongated bar 70 of rectangular cross sectional configuration aε illustrated in Figure 3 having an inclined end 72 received between the pivot lugs 68 and pivotally connected thereto by a pivot pin or bolt 74. The opposite end of the bar 70 is provided with a handle 76 formed by twisting the end of the bar so that it is in perpendicular relation to the remainder of the bar. Aε illustrated, the thickness of the bar 70 is generally equal to but slightly less than the width of the slot 40 so that the forming arm 28 can swing in a vertical plane about the pivot pin 74 from the outwardly inclined position illustrated in Figure 1 with the inclined edge 72 engaging the top surface of the mounting plate 66 to a generally horizontal position as illustrated in Figure 4. When the forming arm 28 iε swung from the position of Figure 1 toward the position of Figure 4, the lower edge thereof will engage the intersecting, cross over overlapping portion 62 of the ribbon 52 and move these portions downwardly by exerting downward clamping force thereon thus moving the portions 62 into intimate, contacting and generally clamped relation. The bottom edge of the forming arm bar 70, when oriented horizontally as in Figure 4, is radiuεed or rounded at 78 to facilitate relative movement between the upper εurface of the ribbon and the edge of the bar which engages the ribbon as the bar iε pivoted about the pivot pin 74. When forming a bow, a thin ductile wire 80 is positioned through the slotε 40 and onto the upper εurface of the baεe plate 22 with the ends thereof oriented εo they do not interfere with placement of the ribbon 52. The endε of the wire can be graεped and wrapped around the portionε 62 of the bow loops after all of the bow loops have been formed thus enabling the bow loopε to be retained in poεition and εecured in poεition prior to the bow loopε being removed from the bow forming device. When forming a bow, a length of the ribbon iε poεitioned between the uprightε and moved downwardly and successive bow loops are formed by looping the ribbon over the thumbs and moving sequential portions of the ribbon downwardly to form the intersecting crosε over overlapping portions 62. The length of the bow loops 64 may be selected by positioning the thumbs 82 on the hands in a selected distance from the uprightε while the ribbon is looped around one thumb by the other hand with the ribbon being pushed downwardly between the uprights which frictionally and resiliently grip the portion of the ribbon inserted between the uprights. Thus, the length of the ribbon loops 64 can be varied such as by providing a plurality of lower loops of a longer length and a plurality of upper loops of a shorter length εo that when the bow is fluffed out, a decorative bow will be formed. The forming arm can be used each time a bow loop is formed or εeveral bow loopε can be formed and then the forming arm can be uεed. Alεo, depending upon the surfaces of the ribbon, the portion of the ribbon received between the uprights can be twisted to maintain the finished surface of a ribbon in upwardly facing relation. Once the bow has been completed, the ends of the wire 80 may be pulled upwardly around the intersecting crosε over overlapping portions 62 and snugged around these portions and twisted to retain the intersection crosε over overlapping portionε 62 in tightly εecured relation. The bow loops 64 can then be fluffed out by moving them laterally to evenly distribute the bow loops on each side of the bow forming device. The partially fluffed out bow can then be removed and the bow loops completely fluffed out so that they are equally spaced around the periphery of a bow. The ribbon 52 is cut from a supply roll or the like and the ends of the ribbon oriented adjacent each other. Various bow configurations and arrangements may be formed by using various types of ribbons, ribbons from various materials and colors with the ribbon loops being of different lengths and configurations. In constructing the bow forming device 20, the base plate 22 may be molded with a dovetail groove 30 therein and is preferably constructed of plastic material. Likewise, the uprights 24 and 26, the mounting end plate 66 with lugs 68 and the end plate 58 may be molded of plastic material. Thiε enables the components to be packaged and transported in a knocked down condition with the components being inserted into the groove 30 and secured in place therein with the mounting end plate 66 being stationarily supported either by screws or by adhesive material. The upright 26 may be positioned against the stationary mounting end plate 66 and, if desired, can be glued into position. The upright 24 remains free to move with the springε 54 biaεing the upright 24 toward the upright 26. The upright baεe 32 maintains the upright plates 38 on the upright 24 parallel to the upright plates 38 on the upright 26 εo that the chamfered edgeε 46 remain equally εpaced during movement of the upright 24 which iε permitted by compression and expansion of the springs 54. The end plate 58 iε preferably anchored by screws 60 to enable assembly of the components and also enable the end plate 58 to be removed to replace the springs 54 in the event replacement becomes necesεary. The forming arm 28 can be constructed of a lightweight metal or of plaεtic material having εufficient rigidity to function to pivot in a vertical plane to engage the portionε of the ribbon extending between the uprightε for moving the portions 62 of the ribbon downwardly into a compressed or compacted relation. As an alternative to using screws or glue, the end plates 58 and 66 can be εnap locked in poεition by forming εe ispherical balls or detentε on the bottom of the end plateε and correεponding recesses or sockets in the bottom of groove 30. Also, the base plate, uprights and end plates can be conεtructed of metal when conεtructing a bow making device for commercial use. Figureε 6-9 illuεtrate another embodiment of the bow forming device deεignated fragmentally and generally by reference numeral 90 which iε identical to the structure illustrated in Figureε 1-5 with reεpect to the baεe plate 92 and uprightε 94 with only one upright being partially illustrated in Figure 6. In this embodiment of the invention, the mounting end plate 96 iε provided with upεtanding, εpaced pivot plateε 98 having a vertically diεpoεed oval εhaped aperture 100 therein with the outwardly facing edge of the pivot plates 98 including a εlot or notch 102 communicating with the oval εhaped aperture 100 aε illuεtrated in Figures 6 and 7. A forming arm 104 iε detachably and pivotally connected to the mounting end plate 96 with the forming arm 104 including an elongated bar 106 of rectangular cross sectional configuration as illustrated in Figure 9 with a rounded lower edge 108. One end of the bar includes a handle 109 formed by twisting one end of the bar and the other end of the bar 106 is provided with a laterally extending pivot stud 110 projecting from both sides of the bar 106 as illustrated in Figure 9. Each of the pivot studs 110 is of cylindrical configuration and includeε oppoεed notcheε 112 defined by parallel bottom εurfaceε 114. The diεtance between the bottom or inner wallε 114 of the notcheε 112 are spaced apart a distance generally equal to the vertical height of the slots or notches 102 in the spaced pivot plates 98 εo that when the surfaces 114 are registered with the notches 112, the forming arm 104 can be moved longitudinally with the εtuds elevated to align the surfaces 114 with the notches or slots 102. By moving the forming arm 104 longitudinally, as illustrated in broken line in Figure 6, the forming arm can be detached from the pivot plates 98. The forming arm 104 can be reattached by reversing thiε movement. Thuε, the forming arm 104 can be pivoted in the εame manner aε in Figure 1 or it can be detached from the pivot plateε 98 and oriented horizontally in the εpace between the upright plateε on the uprightε and then moved downwardly in a vertical manner while maintaining a horizontal orientation to enable the portionε 62 of the ribbon 52 to be moved downwardly without any εliding engagement of the lower edge of the forming arm on the ribbon. Figures 10 and 11 illuεtrate another embodiment of the bow forming device generally deεignated by reference numeral 120 and which includeε a base plate 122 with a dovetail groove 124 in the upper surface thereof receiving upright base plate 126, an end plate 130 having springε 132 mounted thereon for biasing the upright base 126 inwardly. Thiε structure is similar to that discloεed in Figureε 1-5 but in thiε conεtruction, the groove 124 can be cloεed at one end as indicated at 134. Each of the upright base 126 and baεe plate 122 includeε an upwardly extending peg 136 which includeε tapered or bevelled surfaces 138 defining a narrow knife edge 140. The bevelled surfaces 138 are interconnected by a generally semicylindrical surface 142 and the upper inner corner of the knife edge is rounded at 144 to facilitate entry of ribbon portions 146 between the pegs for downward movement between the pegs with the εpringε 132 providing a gripping engagement with the ribbon portionε 146 to facilitate formation of bow loopε and a bow in the same manner as described in connected with Figures 1-5. The forming arm is not used in Figures 10 and 11 but the resilient biaε of one of the uprightε iε included in this embodiment of the invention which enables the knife gripping edge 140 on one of the upright pegs to reεiliently move toward and away from the other and to remain in parallel relation thereto to provide a secure and constant gripping force to hold the ribbon portions 146 and more effectively secure the ribbon portionε when forming a bow aε compared to wood dowels that are anchored to a base at their lower ends and which tend to diverge as a plurality of ribbon εegmentε are inεerted between the dowels thus providing an inεecure clamping engagement with the uppermoεt ribbon segments positioned between the dowels. In the embodiment illustrated in Figures 10 and 11, one of the upright pegs 136 may be formed unitarily with the base plate 122 with the groove 124 terminating in registry with the knife edge 138 on the stationary peg 136. Thus, only the end plate 130, εprings 132, upright base 126 and attached upright peg 136 are εeparate componentε. It iε alεo pointed out that a tie wire will used with thiε embodiment of the invention in the same manner as in Figureε 1-5 in order to form a decorative bow. The foregoing iε conεidered aε illuεtrative only of the principleε of the invention. Further, since numerous modifications and changeε will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation εhown and described, and, accordingly, all suitable modifications and equivalents may be reεorted to, falling within the εcope of the invention.
