FRANKLIN BONAPARTE SHUSTEE, OF NEW HAVEN, CONNECTICUT; LUELLA F. SHUSTEE, ADMINISTRATRIX OF SAID FRANKLIN B. SHUSTER, DECEASED, AS- SIGNOR T0 F. B. SHUSTER COMPANY, OF NEW HAVEN, CONNECTICUT, A COR- IPOIRATION OF CONNECTICUT.

WIRE .STBAIGHTENING AND To all whom it may concern:

Be it known that I, FRANKLIN B. SHUSTER, citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Wire Straightening and Cutting- Oif Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wire straightening and cutting off machines; and particularly to machines of this character constructed and adapted for straightening and cutting large stock. In straightening and cutting to length wire of small diameter the feed rolls run continuously, but with large stock, running from a half inch in diameter, or more, it is absolutely necessary to stop the feed rolls during the operation of the cutting oif lever. As the wire is drawn from a coil mounted feeding and preliminary straightening rolls, together with the forward feeding rolls, have a hard pull to unwind large stock from the reel and carry it through the rotary straightening arbor or roll straightener, and unless the feeding is stopped, when the cutting off lever is operated, the pressure of the incoming wire against the lever will not only retard its movement but will soon wear a groove in its face.

Referring to the drawings :-Figure 1 represents a side elevation of the machine; Fig. 2 is a reverse side of the standard supporting the feeding and straightening mechanism and broken view of the mechanism forward of the cutting off lever on line a a of Fig. 1. Fig. 3 is an enlarged front elevation of the machine, sectional view of the guide bar, cam shaft, and large supporting pipe on l1ne b b of Fig. 1; also broken view of the cutting 03 lever, and broken view of the feed controlling or shifting lever on line a c of Fig. 5, the rest of the feeding mechanism being omitted; Fig. 4 is an enlarged broken view of the machine standard. cutting off lever, feed controlling lever and supporting pipe, and sectional view of the cam shaft on line d d of Fig. 3; Fig. 5 is upon a reel, the rear initial CUTTING-OFF MACH-INE.

an enlarged broken upper plan view ofthe head or standard supporting the feeding and straightening mechanism; Fig. 6 is an enlarged broken detail view of a part of the trippingmechanism; and Fig. 7 is an enlarged detail side elevation of one of the rock shaft arms, sectional view of the rock shaft, apron shaft, guide bar and its apron, and sectional view of a rod in the guide bar. Fig. 8 is an enlarged broken side elevation partly in section of the cam shafts, balance wheel pulley, and sectional view of the cam for actuating the shift lever, showing the key engaged with the balance wheel pulley; and Fig. -9 is an enlarged broken view of that portion of the clutch lever adapted to engage with the key.

Like letters and figures. of reference indicate like parts throughout the several views.

A description of the well known features of the machine will be briefly set forth to show the relation .of my improvements thereto.

1 is the main standard or head supporting the journaled shafts 2, 3 and 4 carrying the initial straightening and feed rolls 5; 6 and 7. These roll shafts are geared together by the pinions 8, 9 and 10 shown at Fig. 5. The forward feed rolls 11 and 12, Fig. 2,

are mounted onthe shafts13 and 14, whichshafts are also geared together by pinions. one, 15,'being shown at Fig. 5. The feed rolls are adjusted in the usual manner by means of the screws 16 and 17 and the hand wheels 18 and 19.

20 is a balance wheel pulley, formerly an ordinary driving pulley, mounted on the shaft 21 journaled in the standards 22 and 23. This shaft carries .the gear 24 meshing with the gear 25 on the roll shaft 3. 26 is a sprocket wheel also mounted on shaft 3, and it carries the chain 27 V to drive the sprocket wheel 28 mounted on the forward lower feed roll shaft 14, and 29 is an intermediate sprocket idler supported on the vertically adjustable standard 30.

30 is the rotary straightener.

" 31 is thecutting ofi lever mounted on the rock shaft 32, which shaft is actuated by means of the roll 33, Fig. 3, in the lower end of NBC said lever, engaging with the cam groove 34 of the cam'35 mounted on the cam shaft 36 journaled in the machine head and the standard 37.

38 is the guide bar whose inner end is secured to the cutting 0d lever and to. the free ends of the rock shaft arms 39, which arms are secured to the rock shaft 32 as shown. is a smaller rock or apron shaft journaled in the upper ends of the standards 41, which standards are supported and' se cured on the large pipe 12. This'rod 40 carries the arms 13 whose lower ends are secured to the guide bar apron -14 as seen at Fig. 3. When, therefore, the rock shaft 32 is actuated to swing the cutting ofi lever to sever the section of wire 44 in the guide bar, it will also actuate the arms 39, which arms, contacting with the tail piece of the collars 45; Fig. 7, mounted on rod 40, will turn said rod to open the apron and let the severed wire section drop from the guide bar. The. coiled springs 46 on rod 40 will actuate said rod in the opposite direction to return the apron to its normal position against the guide bar as soon as the cutting off lever retreat-s.

4:7 is a double arm clutch lever, Figs. 3, 4t and 5, journaled on the outer end of the rod 48, Fig. 5. The horizontal arm 47 of this lever engages with a. groove in the spring actuated key 49 to hold such key back from engagement with the balance wheel pulley 50 when the cutting ofi lever is stationary.

51, Fig. 1, is a gage rod which is located 1n the groove 52, Figs. 3 and 7, to determine the length of the wire sections to be, cut ed.

53 is an adjustable block secured to the outer end of the gage rod and to the trip rod 54, and 55 is a finger connected to the gage rod to which is attached one end of the trip wire 56, while the other end of this wire is attached to the lower end of the vertical arm 47 of the clutch lever, so that, when the end of the incoming wire in the guide bar contacts with the inner end of the gage rod, the clutch lever 47 will be actuated to release the he and, by means of its spring 6, Fig. 8, a low it to engage with the contmuously running balance wheel pulley 50 and actuate the cutting off lever in the usual manner. After the clutch lever has released the key 49 it will drop in readiness for the inner face of the groove f of the key to engage with the incline face of the lever to force the key out of engagement with the balance wheel pulley when the shaft 36 has completed one revolution.

My present improyement consists in mechanism for temporarily halting the feeding mechanism durin the operation of cutting off a section of wire, and it applies particularly to machines built ex ressly for straightening and cutting ofl' large stock, for which purpose the cam 57 is mounted on the shaft 36. 58 is a roll carried by the shift lever59 to engage said cam. This lever is pivotally supported on the bed bracket 60 as shown.

61 is a short trip lever pivoted in the bed bracket 62, and 63 is a finger in one end of this trip lever adapted to engage with the block (it on the end of the shift lever 59 and lock the lever in the position shown at Figs. 3, 4 and 5 while the feed rolls are in operation and the wire is being fed. When, therefore, the end of the wire contacts with the end of the gage rod in the guide bar to actuate the trip rod 5 1, both trip wires, viz., 56 and 65, will be actuated, the former to release the key 49 and set the cam shaft in operation as before explained, and the latter to actuate the trip lever 61 and release the shift lever and place it under the control of its retraotile spring 66, which spring will cause the opposite end of the shift lever to move its sleeve 59* toward the continu ously running balance wheel pulley 20 and engage the finger 67, which finger is connected with well known clutch mechanism (not shown) which stops the feed rolls. Releasing the shift lever, as above described, will place the roll 58 of said lever against the straight face of the cam 5'2, and the finger '63 of the trip lever into the position shown at Fig. 6. The said roll will run against the straight face of the cam during the operation of the cut-ting ofi' lever 31, and when said operation is finished the incline face 57 will engage the roll and reloch the shift lever and set the feed rolls again in operation and also bring the cutting 0d lever .31 to a state of rest.

Referring to Fig. 4, 68 is an arm secured to the same rod on which the clutch lever 4t? is journaled, and this arm $8 carries at its lower end the housing 69 in which is located the spring pin 70 and its compression spring 71 and the spring adjusting screw 72. The spring 73, Fig. 1, on the trip rod 541, which spring is adjustably located between the collars 74: and 75 serves to reduoe the strain or push for tripping the clutch mechanism to actuate the cutting 0d lever, and thus assist the wire when contacting with the end of the gage rod to force the weight of all the constituent parts out with but little resistance. The sprin 71, Fig. at, will force the horizontal arm 4 of the clutch lever into engagement with the key or clutch pin 1-9 after the cutting off operation has been completed. By reason of the two springs acting in opposite, directions, the gage mechanism can be nicely balanced by the proper adjustment of said springs.

The adjusting screw '16 in the lower end of arm 68 forms a stop for the clutch lever to allow its arm an to rise just far enough to release the key or clutch pin'.. it also prevents any vibration of the clutch lever lift tea

and gage rod mechanism,

caused by the equalizing springs 73 and 71 acting in opposite directions.

While I show my improved tripping mechanism used iniconnectionwith a rotary straightener, it is equally adapted-for roll straighteners; the former is employed where round stock is straightened and cut, while the other is used for square stock.

Having thus described my invention. what I claim is: H,

1. In awire straightening and cutting off machine of the character-described, the combination with the wire feed rolls, guide bar and cutting 01f lever and its actuating shaft, and a continuously running balance wheel on said shaft, of a cam on said shaft, a shift lever adapted to be actuated by said cam, a continuously running balance wheel pulley for driving the feed rolls, a trip lever for locking the shift lever when the feed rolls are in operation, a clutch lever for locking the cutting off lever, trip wires connecting the trip and clutch levers so that, when the incoming wire in the guide bar contacts with the gage rod in the guide bar, both the trip lever and clutch lever will be concurrently actuated, the former to release the shift lever and stop thefeed rolls, and the latter to release the cutting off lever, and means on said cam for relocking the shift lever, and for relocking the clutch lever.

2. In a wire straightening and cutting ofi machine, the combination with wire feeding mechanism, cutting off mechanism, guide bar, gage rod, tripping mechanism connected with the gage rod, of wires connecting the tripping mechanism with the feeding and cutting off mechanisms whereby both the feeding and cutting oif mechanisms are simultaneously actuated by the gage rod.

In testimony whereof I afiix my signature in presence of two witnesses.
