The machine is designed and constructed to perform ,substantially the following cycle of movements or operations:

1. The feed table for the cord or fringe to which the tassels are to be applied, turns;

2. The tube or feed for the tassel material moves downwardly passing through one of the holders `on the feed table;

3. The holding clamp or jaws engage with the tassel material which for convenience will hereinafter be designated as the thread;

4. The thread feed goes up;

10. Stapling pin retracts and lower stapling die moves up and finishes staple or ring;

11. Finishing knives cut off end of tassel;

12. Blower blows away ends, which completes the cycle preparatory to the next movement ofthe feed table.

The machine for accomplishing these operations, as shown in the accompanying drawings, is provided with a frame having a top or table 20 and legs 21. A driving shaft 22 is carried in bearings 23 secured to the lower part of the table 100 and is turned in any suitable manner as by means of power or by means cf a hand wheel 24. A ro tatable feed table or disc v25, shown particular ly in Figure '7, is arranged at the front of the ma chine and is provided with a plurality of holders 26 for supporting the fringe, cord, or any other article or articles to which the tassels are to be shown in Figure 14, the fringe 27 is provided with loops 28, which loops engage with that short tangential portions 85 or staple feeds in off end bent to U-shape to L are presented around the outer periphery to which the tassels are attached. It will however be obmoves upwardly due to the action oi the sp1 ing 62 served that rings or other shapes may be applied on the lever 60 thus leaving a section of thread to the holders as desired for ieceiving the tassels or material between the clamp and the lower end The feed table is secured to a vertical shaft 29 which is mounted in a bearing 30 secured to the top of the table 20.

The lever 106 is provided with a pin or roller 109 which engages with a cam 110 on the shaft 84. I Y

VWhile the fingers 92 and 93 are holding the ends of the tassel, a stapling pin 114 passes over the top of the same preparatory to 'applying the wire staple or ring for completing the tassel. This pin is slidably mounted in a sleeve or bearing 115 supported from the main frame above the feed table at the front of the machine. The pin is provided with a slot or keyway in the top which is engaged by screws 116 in the sleeve, as shown in Figure 6, which prevents the pin from rotating and holds the inner flattened end in proper position. The pin is provided with a pivot 117 which engages with the slot in the end of a lever 118 which is pivoted at 119 to a support on the main frame. The opposite end of the lever has a roller 120 which engages with a cam 121 on the shaft 142 for moving the lever in one direction. The lever is moved in the opposite direction, or held against the cam, by a spring 122, one end of which is secured to the lever and the other end to a fixed bracket 123 on the frame,

When the stapling pin has moved inwardlyover the tassel, the stapling or ring wire 124 is fed in over the top of the same as indicated in Figure 9. The supply of wire, which may be either plain or covered, is carried on a roller 125 mounted on bearings 126 at the side of the machine. It passes from this roller through a tube 127 then through straightening rolls 128, through a slot on a feed block 129 (Fig. 7) and finally through a combined guide and out off member 130 which is secured in the frame adjacent to the tassel forming devices, as shown in Figures 9 and 10.

The wire is fed intermittently at the proper times by a feed dog or lever 131 having teeth for engagement with the wire to slide it along the block 129. This lever is pivoted at 132 to a slide 133 mounted in a suitable guideway, as shown in Figures 3 and 7. The outer end of the lever 131 is provided with a roller 134 which is engaged by a peculiarly shaped camL 135 on the shaft 84. The slide 133 is held in normal or retracted position by a spring 136,` one end of which is secured to the pivot pin 132 and the other end to a bracket 137, which bracket also supports the straightening rollers 128. The cam 135 is so shaped that at the proper time, it rst causes ythe outer end of the lever 131 to swing and bring the toothed inner end into engagement with the wire. Then, as the cam continues to rotate, it pushes inwardly on the roller causing the slide 133 to move to the right as shown in Figure 7, the proper distance to feed the wire. When the slide has moved to its extreme position, the roller 134 becomes disengaged from the cam 135 and the spring 136 draws the slide and lever back to initial position.

The portion of the wire 124 which projects through the die 130 is cut off at the proper time by the knife edge 138 of an upper staple forming die 139 as indicated in Figure 9. This provides a short piece or blank for forming the staple or ring 140. As the die 139 moves downwardly it causes the ends of the wire to be bent down over the pin 114 and over the folded tassel material 51 preparatory to being bent around the same. When the staple has been partially formed, the pin 114 is withdrawn and the wire is completely bent tightly around the tassel to form the binding ring, as shown in Figure 11. This forming is done by a center forming die 141 which coacts with the die 139 and a lower forming die 142 which complete the ring, as shown in Figure 10.

The die 139 is mounted in a suitable guideway 143 and is held in raised position by springs 144 which are interposed between a plate at the top of the die and frame, Figures 3 and 8. It is moved downwardly, to cut off the wire and form the staple, by a cam 145 which is mounted on a horizontal shaft 146 carried in suitable bearings 147 and 148 on the main frame. This shaft is driven by a sprocket wheel 149 which is engaged by a chain 150 driven from a sprocket wheel 151 on the driving shaft 22.

The center die 141 which slides in the die 139 is held in raised position by springs 152, (Fig. 3) which coact with the plate 153 at the top of the die, as shown in Figure 8. This die member is moved downwardly at the proper time by a cam 154 mounted on the shaft 146.

The lower stapling die 142 is mounted in a suitable guideway 155, Figure 6, and is normally drawn downwardly by a spring 156 one end of which is secured to a pin 157 in the die and the other end to a pin or screw 158 in the frame. The lower end of the die 142 has a projection 159 which engages with a cam 160 on the main shaft 22, which causes the die to be raised at the proper time as heretofore described. When the dies have coacted to complete the staple or ring 140 it will be tightly formed around the tassel so as to hold the thread thereof securely together and to make a permanent nish for the tassel,

When the tassel has thus been formed the ends are snipped or cut off by adjustable knives 161 and 162 to cut the same the proper length and to make the end of the finished tassel even. The knife 161 is mounted in a guideway 163 which may be adjusted, forward and back by adjusting screws 164, Figure 3. The knife is held in raised position by a spring 165, one end of which is secured to a screw 166 on the knife and the other end to a screw 167 on the frame. This knife is moved downwardly at the proper time by a cam 168 on the shaft 146. The knife 162 is mounted in an adjustable guideway 169 so that it will coact with the knife 161, Figure 6. This knife is pressed downwardly by a spring 170 which works over a guide rod 171, one end engaging with a shoulder 172 on the knife and the other end against a shoulder on a bearing 173 for the upper end of the rod. This knife is moved upwardly at the proper time by a cam 174 on the shaft 22. As soon as these knives coact or out off the end of the tassel, as indicated in Figures 14 and 18, the claws or fingers 92 and 93 release the severed ends and the various mechanisms return to proper position for making the next tassel.

It is necessary or desirable to dispose of the short severed ends of the thread in order to prevent them from interfering with the operation or clogging the machine. This is done by means of suitable blowing means. This consists of an air pump 175 which is secured to the frame and has a cross rod 176 Xed to the piston rod 177. Tension springs 178 are secured to the ends of the rod 176 and to the frame and tend to hold the rodand piston in depressed position. A curved arm 179 is also secured to the piston rod and has an inwardly extending branch 180 formed of two strips, at the end, which is in alignment with the piston rod. This branch has a roller 181 which engages with a cam 182 on the shaft 146. This cam is so shaped that, just prior to the severing of the tassel ends, the piston will be drawn upwardly and, when the ends have been severed, the

piston will be forced downwardly by the springs 1'78 to force the air from the cylinder. The air from the cylinder or pump is conducted through one or more tubes 183 to points adjacent to the location of the severed ends so that these ends will be blown away by the puff of air from they pump.

One of the particularly novel and important features of the invention is the feed mechanism for feeding the fringe or articles to which the tassels are to be applied. By having a plurality of holders which move intermittently, but continuously in the same direction, the operator has sufficient time and space to apply the loops or the like to the holders so that the fringe or other articles may be rapidly fed through the machine and the tassels applied thereto. As the table rotates, the operator withdraws the fringe or the like with the completed tassels from the opposite side of the feed mechanism which is done very readily by merely pulling the fringe upwardly away from the holders. Another important feature is the provision of means for positively pushing or projecting the tassel material or thread through the holders and consequently through the loops or rings placed thereon and to which the tassels are applied. These and other novel features permit the work to be done with comparative rapidity and insure the forming of neat and substantial tassels. While I have shown a preferred form of my invention it is apparent that changes may be made in the arrangement of parts or details of construction to adapt it for different goods or the like and therefore I do not wish to be limited to the particular arrangement or parts herein shown and described except as specified in the following claims, in which I claim.
