ported on a bracket B on the frame A in opposition to a cutting knife. 13 mounted on a knife lever B pivoted on the base A on the spring B. A cam roller 13 on the knife lever B is held by this spring B in engagement with the cam B on a cam shaft B". This cam shaft B is rotatably mounted on B in the frame A and is provided with a miter gear B in mesh with the miter gear B The relative angular positions of the feeding cams or segments and the cutting cam are such that the cutting cam operates to cut off the wire only after the feeding cams have fed the wire forward a suitable distance.

The wire as it is fed forward beyond the cut-off apparatus passes-across the ends of the anvil bars C C. These anvil bars have rotatably mounted thereon sleeves C C which sleeves carry twisting fingers C C pro ecting down beyond the wire to leave room for the wire between them and the anvils. These sleeves C C are journaled in bearings C supported on the frame brackets C The sleeve C is provided with a ear C in mesh with the sliding rack C"; and the sleeve C is providedwith a gear (1 in mesh with the gear C which gear is in mesh with the rack C and rotatably mounted on the lug C projecting from one of the brackets C". The rack is slidably mounted on the guides C on the brackets C and has at one end a cross head C to which it is adjustably attached. This cross head reciprocates in the guide C on the bracket B and carries an arm C which arm is provided with a cam roller C in engagement with the cam 6 on the shaft A This cam is so angul'arly positioned with respect to the feed cams A A that a reciprocation of the rack takes place only after the wire has been fed in a suitable distance and cut off. The gear C is provided in order that the two twisting fingers may rotate in opposite directions in response to the movement of the rack. The spring C is provided for the purpose of yieldingly holding the rack always against the cam.

Intermediate the anvil bars C C and loop forming mechanism is located the mutilated sleeve D supported on a bracket D projecting upwardly from the base A. This sleeve is closed for substantially its entire periphery but opened through an angle of approximately at the bottom. In this ASSIGNOR TO BATES VALVE BAG sleeve is rotatably mounted a twisting head D which head is substantially solid except for an angular slot formin I an arc of approximately 60 and exten ing slightly beyond the center thereof to permit passage of the wireA". This twisting head extends outwardly beyond either end of the sleeve D terminating in tongues D A spring D :is fastened at one end to the sleeve D and 0.

at the other to the head D to yieldingly hold the twisting head in position shown in Fig. 9. Teeth D are cut in the periphery of the head D and are in mesh with the mutilated gear D on. the shaft B" which mutilated gear is toothed for such a distance as to rotate the twisting head through approximately 180. The two ends of the twisting head D are slotted as indicated in Figs. 5,

7 and 8. The slot'is normally narrow but enlarged or deepened as at D on the side of the head toward the anvils C C and is provided with a cam surface D to guide the 12 and 13.

The anvil bars C C are slidable in the sleeves O C and are provided at their upper ends with the reduced portions E E? respectively which reduced portions are engaged by the forksE. E on the rocker arms E These rocker arms are keyed to the shaft E journaled on the brackets C" and on the bracket A. This shaft E is provided with a cam arm E carrying a cam roller E in opposition to a cam E on the shaft A, the roller being held against the cam by a spring E As the shaft A. rotates the cam E being angularly arranged so as to operate subsequently to the forming of the tie will rotate the shaft E and lift up the lever E and thus pull up on the anvil bars and free them from the tie. The wire subsequent to itsbeing cut oil" and prior to the final twisting movement is held in the head D by the plate G which projects into the slot to hold the wire in position, and is mounted on the rock shaft G and adapted to be controlled by the lever G provided with a cam roller G in opposition to the cam G which is carried by the shaft A In order to provide for increased length of wire tie one of the brackets C is slidably mounted on the base A and the holding bolts travel in the slot A so they may be loosened to give any suitable length of wire. When this is done it is only, necessary to replace the twisting head D without interfering.

with the operation; The shaft E" is rovidedwith a key-way E to which is splmed one of the arms E to enable the shaft E to lift the anvil. The rack is of suificient length to provide for this adjustment and since the movement of the rack is the same at all points alon it the operation of the twisting anvils wil be the same no matterwhat the length of the ties produced. The bracket C in order to hold it rigidly in position when locked or bolted is provided with a tongue C and assists in anchoring the bracket C.

The use and operation of my invention.

are as follows: The wire is fed into the-machine from any suitable source of supply, not here indicated, by the rotation of the two feeding cams which grip the wire and once each revolution feed it forward a distance equal to the peripheral distance during which they are in opposition, which distance may be said to be anything from zero to the total periphery of the cam, namely, one-half the circumference, by merely adjusting the angular position of the two cams with respect one to the other. When this feeding forward has ceased owing to the feeding cams having passed out of engagement with the wire, the wire cutting cam will cause the wire cutting arm to swing forward toward the wire and the anvil against the yielding pressure of the spring to cut the wire. This wire will in the meanwhile be held in position in the downwardly open V-shaped groove in the turning mandrel by the holding plate shown at G in Fig. 3. While the wire is here held and subsequent to the cutting off of the wire cam 0 will force the rack C to the right in Fig. 1, rotating the two vertically disposed twisting mandrels through substantially '270 degrees, the pressure of the pin C on the mandrel against the wire will as this pin rotates, cause the pin to slide along the wire and fold or bend it into the shape shown in Fig. 11. The wire will then be gripped on the mandrel and the support of the leaf G will no longer be needed. This leaf is then allowed to drop down and the mandrel D is rotated, bending the ends of the wire about the body of the wire to produce the result shown in Figs. 12 and 13.

Attention is called to the peculiar shape of the slot D shown in Fig. 8. This slot is broad at the point where the wire enters it in order that there may be no possible chance of the wire missing the slot. It narrows down, however, as the wire is rotated to bring the end of the wire from below firmly up against the body of the wire when it reaches the-part D. Subsequent to this twisting movement the spring D draws the mandrel D back to the position shown in Fig. 9 and the cam E rocks the shaft E to lift up on the bell cranks E and raise the wire engaging portions of the anvil bars 0, C to draw them out of engagement with the wire tie and permit the tie to fall freely into any suitable receptacle. All these acts are performed during the half revolution from the. time when the feeding cam lets go of the wire to the time when it is ready to again commence feeding the wire into the machine, although, of course, there may be a slight amount of lag, as .no harm would result so long as the end of the wire has not quite reached the first mandrel before it returns to its normal position.
