BOW MAKING MACHINE Filed April 19, 1963 5 Sheets-Sheet 3 United States Patent O M 3,180,542 BOW MAKING MACHINE Gershorn N. Carmichael, 6315 Rohinhood Lane, Merriam, Kans. Fiied Apr. 19, 1963, Ser. No. 274,200 21 Ciairns. (Ci. 223-46) This invention relates to a machine for making decorative bows substantially automatically from tape or ribbon in strip form, making it possible, if desired, to utilize a roll of the ribbon that is in turn carried by a reel rotatable on a stand. In making the bow a special stud or fastener is also employed having the characteristic of being able to pierce the ribbon and after piercing becoming attached thereto. The bow itself consists of a multitude of loops radiating outwardly from the centrally disposed fastener.

It is the most important object of the present inven tion to provide a bow machine that is economical and easy to use, experience having indicated that skilled operators are unnecessary and that within a very short period of time virtually any operator can be taught to properly use the machine in its intended manner.

It is another important object of the instant invention to provide a bow making machine that appreciably speeds up bow making operations and, here again, it has been found that through use of the instant invention the average operator is able to make up to 225 bows per hour.

Another important object of the instant invention is to provide a bow making machine that can be used to produce both star bows and pom-pom bows and -to provide an almost endless number of combinations of design of both of such basic types.

A further important object of my present invention is the provision of a bow making machine that is especially adapted for use in retail stores to increase gift sales, and therefore higher profits, because of reduction in wrapping time, thereby releasing personnel for increased selling time.

FIG. 14 is a perspective view of one type of star bow made through use of said machine; and

FIG. l5 is a perspective View of another type of star bow made by employing the bow making machine of the present invention.

As illustrate-d in FIGS. 1 and 2 of the drawings, ribbon 16 from which decorative bows (such as those iliustrated in FIGS. 13, 14 and l5) may be made is unwound from a supply roll 18 that is in turn carried by a reel 2Q. A special stand 22 has releasable connection with a base 24 (see FIG. 3) as, for example, by one or more headed boits or the like 26 received in slots in stand 22..

Stand 2.2 has an inclined plate 28 provided with an axle 3b rotatably receiving the reel 2G. Such inclination, together with a facing 32 of frictionable material on the plate 2S and against which ythe reel 20 bears, operates to retard rotation of the reel 22 and, therefore, overrunning during operation of the bow making machine. The axle 39 is slanted downwardly, for example, about 5 degrees out of normal to plate 2S so that the reel 2i) will always engage facing 32 below axle 30.

For reasons hereinafter to be made clear, any number of additional reel supporting stands may be provided; therefore, the stand 34 of similar nature is releasably attached to stand 22 when it is desired to use ribbon 36 in lieu of ribbon 16 or in combination therewith. FIGS. l and 2 also illustrate the ribbon 16 passing beneath a guide pin 38 and thence longitudinally of the base 24 thereabove onto a convex ribbon receiving surface 40 of an anvil 42, forming an integral part of `the base 24.

Referring now more particularly to FIG. 3, the base 24 supports a member 44 that reciprocates about a horizontal axis through the medium of a shaft 46. The member 44 is in the nature of a substantially L-shaped arm swingable on 4the shaft 46, as illustrated in FIG. 1, the base 24 being provided with upstanding ears 48 that are traversed by the shaft 46.

Arm 44 has a bearing 56 that rotatably receives a spindle 52 which in turn supports a holder 54 as best seen in FIGS. 1l and 12, for a stud or fastener 56 which retains Athe loops of the bows, as will hereinafter be explained.

Holder 54 cooperates with the spindle 52 in supporting the stud 56 and includes a tube 53 that is reciprocable on the spindle 52 and yieldably biased toward the lower end of its path of travel by a spring 6@ coiled about the spindle 52 between the tube 58 and a set collar 62 a-ttached to spindle 52.

Tube 58 has a T-shaped slot 64 (see also FIGS. 3 and 5) which receives pivot pin 66 carried by spindle 52 and rotatably receiving a cam release 63 that is placed in use during insertion and 'removal of the stud 56. Pin 66 is eccentric to the circular cam edge of the release 68 so that when the latter is rotated to the kposition shown in FIGS. 3 and 1l, tube 58 is raised with respect to spindle 52 against the action of spring 63 because of engagement of the release 68 with ontturned ilange 7i? on tube 58. This places the lower end of the slot 64 in proper register with a recess 72 in the lower end of spindle 52 to permit insertion of head 74 of stud 56. A slot 76 in the bottom of tube S8 clears shank 78 of stud 56 but such slot 76 is n ot sufficiently large to clear the conical ribbon piercing boss 8i) on the lower end of the shank 723. Hence, when the cam 61% is released, spring 6i) forces tube SS downwardly until the bottom of the latter engages the upper surface or shoulder of the boss 89, as seen in FlG. l2.

Rotation of the spindle 52 is responsive to swinging of the arm 44, and to this end an elongated rack device 52 (FIGS. 3, 5, S, 9 and l0) is carried by the arm 44 for reciprocation relative thereto within a channel guide 84 (having bearing Si) integral therewith) releasably attached to the arm 44 therebelow. The guide 34 is cut away to clear a pinion 86 which meshes with the rack S2.

Pinion 36 is an integral part of a cylinder S3 which in turn forms a part of clutch means 99 provided to limit rotation of the spindle 52 in but one direction. Clutch means 90 includes also a cam wedge 92 (FIG. 7) keyed tothe spindle 52 Vand recessed to receive a plurality of rollers 94 housed within the cylinder SS. In a well-known manner, the cylinder 831s attached to spindle 52 for free rotation with respect thereto when tl e pinion 86, and therefore the cylinder SS, are rotated anticlockwise, viewing FIG 7. When, however, pinion 86 and cylinder 38 are rotated clockwise, rollers 94 bind between cam wedge 92 and the inner face of cylinder'SS, n

causing spindle 52 to rotate therewith. y

A drag is placed on spindle 52 to prevent anti-gradey rotation, i.e., anticlockwise, by'a spring 96 coiled. on spindle 52 between bearing Si) and set collarv 62. Additionally, a spring loaded ball detent 98 (FIGS. 9 and 10) in the bottom of the channel guide 84engages the pinion 86 and'partially seats between the teeth thereof,`

operating to hold the spindle 52 in its attained rotative position at the end of each stroke of the arm 44.

Such stroke of arm 44 is, of course, limited in a down-v ward direction by they anvil 42, as will hereafter be explained, and is limited in the opposite or upward direc, tion by a shiftable element 100 -best'seen in-FIGS. 3,4

and 6. Such stroke varying means 109 has a common support in the shaft 46 with the arm 44 that is normally held against swinging movementabout the axis of shaft'46 by a spring latch means 102 carried by the base 24. Latch 102 has a later-al lip 104 insertable in any one of a number of notches 106 in element 100 arranged in an arcuate row concentric with shaft 46. The rotative position of the element 100 may be changed simply` by pulling on a knob 108 of latch 102 so as to withdraw the lip 104.

Arm 44 has a transverse fixture 110 inthe nature of a pin disposed to engage the element 190 whenarm 44 on the anvil 42, yieldabiy biased downwardly againstthe surface wand has an arcuate, wire end 134 operating to maintain the ribbon 16 Vin proper alignment with the opening 132 during upward swinging movement of the arm 44, and therefore, while the ribbon 16 is pulled from the roll 1S.

Assuming the ribbon 16 to be in place on the sur- Y face 49,' held thereon by the end 134 of guide 1391and overlapping the opening 132, and .assuming the fastener 56 'to bein place as illustrated irrFIG. l2, arm 44 is swung downwardly about the axis of shaft 46. The. boss Si) of stud 56 pierces the ribbon 16 midway of its longitudinal edges and then continues into the opening 132 as the holder 54, Le., tietube 58, engages thefanvil 42. Continued downward movement of the spindle 52 with respect to the tube 58 assures complete piercing of the. ribbon 16 until the latter is disposed between the boss 86 and the bottom of the tube 5S.

Hence, as the arm 44 is swung upwardly, the pressure onspring 69 is released, causing the tube 58' to be extended to a position where the ribbon 16 is gripped between the lower end of the tube 58 and the upper face of the boss 80,` the ribbon 16 then, of course, being threaded on the Vshank 78 of the stud 56.'

Consequently, as upward swinging vmovement of the arm 44-is continued, a predetermined length of the ribbon 16 will be stripped from the roll 18 'as the reel 2t) rotates. on axle 3()V and as the ribbon 16 .slides along It canvnow be seen that the size of each of the loops i 131 of bow .128, and therefore the diameter of the latis swung to the upper end of its path of travel. More i particularly,v the .fixture 110 engages an extensible abutment 112 constituting a stud `bolt in the element 166,.y

permittingfine adjustment.

The element 100 valso forms a part o f the mechanism for imparting rotative movement to the spindle 52 because the rack 82 is pivotally connected :therewith throughthemedium of a link 114 (see FIG. 3). Arm 'f 44 is yieldably biased toward the upper endof its path v 6) on lever 124 is pushed-inwardly to slide a spacer 126 along fixture 116 to a position interposed between the abutment 112 and the fixture 110, thereby controlling the rotation of spindle 52, as is about to be explained. The star bows 118 and 120 shown in FIGS. 14 and lS'are produced when the rotation control spacer 126 is positioned as illustrated in' FIGS. 4 and 6 where it will not strike the abutment 112 when the arm 44 is in the dotted line position shown in FIG. l.

Prior to placing the machine in operation, ribbon 16 is threaded across the surface 46 of anvil 42 beneath a spring guide 13) and over an opening 132 in the anvil 42 for clearing the stud 56. VThe guidel) is mounted FIG.

ter, is determined by lthe extent of upward swinging movement of arm 44 which in turn determines-the amount of ribbon 16 stripped vtrom the roll 18 during each stroke. of the arm 44. Upward movement of arm 44 is in turn determined by fixture 110 striking abutment 112; accordingly, positioning of the element 100 through use of latch v102 determines the diameter of. the bowi128.

It is to be noted at this juncture that the connection` of rack 82withelement 100 through link 114 is, ineect,

'- a connection of rack 82 with the-base. 24 because the to the'rack82, causing rotation of the pinion 86 in both directions. However, on the. upstroke of the arm 44 cylinder 88 rotates freely. without imparting rotative movement to the spindle 52. As arm 44 is swung downwardly, rack 82v imparts rotative movement to the spindle 52 through the clutch 96 until the rack 82 is no longer Ain mesh with the pinion 86, whereupon, during continued downward 4movement of the arm 44, spindle 52 remains stationary with respect to arm 44. Hence, there 1s an assurance thatholder 54 doesnot rotate while the tape 16 is being pierced and while the spring 60 is being.

compressed, yavoiding improper deflection or distortion of tape 16.

The first'loopv 131 is, therefore, formed, whereupon the stud 56 again pierces the ribbon 16 :and the operation is repeated. number of loops 131 which can be provided in a single bow 128 .is determined in part at least by the length of shank 78 which initurn determines the number of overlapping layers Aof the tape 16 that can be pressed between head 74va`nd boss 8).

When the spacer 126 is in the position shown in FIGS.

4 and 6, fixture 119 engages the abutmentv 112; therefore, arm 44 moves to the dotted-line position shown in 8. FlG.' lO of the drawings illustrates the relative t should be noted at this juncture that the.

ans-0,542

positions f the rack S2 and the pinion 86 when the arm 4 is in the dotted line position shown in FIG. 8. On the other hand, when the s acer 126 is shifted to a position where it will engage the abutment 112 on the upstroke of arm da, the limit of such stroke will be as shown in full lines in FlG. 8. And, under such condiions, the relative positioning of the rack S2 and pinion 86 will be as illustrated in FIG. 9. This simply means that the amount of rotation of the spindle 52 on the downstroke of arm 44 is decreased when the spacer 126 is positioned in alignment with the abutment 1i?. because of the fact that only a portion of the rack 82 becomes effective to rotate the pinion 86 before rack 32 and pinion S6 are out of intermeshing relationship.

in the invention as illustrated, and by way of example oniy, when the lever 12d is positioned as illustrated in and 6, the total rotation of the spindle 52 during each downward stroke of the arm 44 is in the order of 210 degrees. On the other hand, when spacer 125 is shifted so as to operate as a stop for the arm 44 the rotation of the spindle 52 is in the order of 150 degrees. If he rotation oi spindle 52. is greater than 180 degrees, the resulting bow 113 will consist of a number of loops 133', each having a twist which diierentiates the star bow 11S over the pom-pom bow 128. In other words, if the rotation of the spindle 52 is less than 18'() degrees, the loops 131 of the resulting bow 128 will not have the twist that is shown in the loops 133 of bow 118- It can now be appreciated that a rather large number of combinations can be selected. For example, the length the loops 1.3i of each layer mili/'be PfOgfeSSVey de' creased simply by releasing latch 162 and Swinging the element 18) clockwise viewing FG- 3 S0 21S O Permit arm 44 to swing farther in its upstrolie, thereby pulling a greater length of ribbon 16 from roll 18.

Another variation, by way of example only, is to rst produc?, one or more layers or courses of loops 131 and thereupon actuate knob 122 to produce additional layers Gf lcops 133, thereby presenting a combination pom-pom and star bow. And, all the while, the operator may change the size of the loops 131 and/or 133 simply by manipulating the latch 102.

Still another variation is to use the ribbons 16 and 36 simultaneously, threading the same beneath the wire end 13j. in overiap ing relationship, whereupon the stud 56 wiil pierce both tapes. The result is illustrated in the bow 126 wherein the loops 133 are made up of both ribbons 15 and 36, the latter being narrower than lthe ribbon 16, if desired, to produce an unusual and attractive ecct, particularly if the ribbons 16 and 35 are of contrasting colors.
