JOHN S. BARNES, OF DETROIT, MICHIGAN.

WIRE-GRITAIPENG MACHINE.

Application filed October 7,

To all whom. it mai Concern:

Be it known that 1, JOHN S. Bannns, a citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful lmprovement in Wire-Crimping Machines, and declare the following to bee full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in wire crimping machines and one of its objects is to provide means whereby the wire as it is crimped may be cut up into predetermined lengths to serve as pickets in the manufacture of wire fence :or if desired the mechanism employed to cut the wire into short lengths may be thrown out of gear that fence line wires of any desired length may be crimped, or extended lengths of wire crimped for any other purpose.

Another feature of the invention resides in the fact that several pickets may be made at the same time ;or several crimped continuous strands may be formed by'feeding a plurality of wires simultaneously to the machine.

In the drawings accompanying this specification:Figure l is aplan view of the machine. Fig. 2 is a front elevation of the machine, the legs or supporting frame being broken away. Fig. 3 is a cross-sectional view on line a rc of Fig. 1, showing parts broken away and in elevation. Fig. 4 is a vertical sectional view on line g y of F 1, showing parts broken away and in elevation. Fig. 5 is an enlarged detail in section of one of the adjustable guides employed to direct the strands of wire to the crimping rolls. Fig. 6 is a detail of one of the gears showing the adjustable segmental cam for operating the wire cutters. Fig. 7 is a sectional view of a detail showing the operat ing lever as connected with the clutch controlling mechanism. Fig. 8 is an elevation of a detail with parts broken away and in section, showing the swinging bar, the gear with a lug for forcing the swinging bar out of its line of travel, and a portion of the cutter bar actuated by the swinging bar. Fig. 9 is a detail view of the product of Specification Letters Patent.

Referring to the letters of reference shown on the drawings: A indicates the frame of the machine. B the main drive shaft mounted in suitable bearings. B a fly wheel, which also serves as a driving pulley.

B is a loose pulley and B is the main driving gear mounted onthe shaft 13.

G is driven shaft supported in bearings c on which is keyed one of the crimping rolls D. Located directly over the shaft C is the shaft D, supported in adjustable bearings mounted on the standards 0, rising from the upper half of the bearings 0.

D is a crimping roll which acts in conjunction with the roll D.

D is a gear mounted on the shaft D being driven by the gear C keyed to the shaft C.

C is one portion of a clutch mechanism keyed to the shaft, which may be secured to or form an integral part of the gear C. C is the other interlocking portion of the clutch mechanism, being loosely mounted on the shaft C to provide for lateral movement of the former on the shaft.

C is a gear loosely mounted on the shaft C being driven by the gear B The gear C is provided with a channeled hub C on which is sleeved a loose collar E. Adjacent to the channeled hub and between it and the clutch portion C is a gear F, also loosely mounted on the shaft C to admit of its lateral movement.

As indicated in Fig. 8 the gear 0 and the clutch portion C is keyed to the shaft 0; while the clutch portion C the gear F, the gear (1* with its channeled hub C", are joined together and are practically integral, and these parts are loosely mounted on the shaft C in order that the clutch portion may be thrown into interlocking engagement with the clutch portion C 0 is a spring mounted on the shaft between the gear C and the bearing 0 serving to force the clutch mechanism into interlocking relation.

E is a lever engaged at one end to the collar E and at its other end it is pivoted to a bracket 6 mounted on the slotted standard G which is bolted to the frame of the ma chine.

F is an idle gear journaled in the standard G and meshing with the gear F.

F is an interchangeable gear, the shaft of j which is supported in the slotted way 9 of the standard G. In one face of the gear F l, is formed a concentricchannel (see Fig. 6) to receive a segmental cam F designed in the rotation of the gear to encounter a lug E mounted on the lever E, the purpose of which is to throw the clutch mechanism out of gear and against the action of the spring C.

The wire is fed to the crimping rolls from a series of reels (not shown) through a plurality of guide tubes H supported in independent boxes H" (see Fig. 5) provided on the inside with an annular rib h, on both sides of which is a depending cap or set screw it, their purpose being to regulate or govern the angle given to the tube and thereby the direction of the wire as it is fed to the rolls. The several boxes H are supported in a slotted frame H to which they are bolted and in which they may be adjusted with respect to each other.

I is a platform supported 7 on the bed frame of the machine, having a series of channels to receive the several wires as they are delivered from the crimping rolls; and I is a top plate bolted to the platform to cover the channel grooves.

J is a steel strip set in the edge of the platform acting in conjunction with movable cutter bar J to form a cutting edge for severing the wire.

2 is a retaining strip or guide for the cutter bar held in position by the bolts J which pass through slots in the cutter bar (not shown) adjacent to the ends of strip.

K is a swinging bar (see Figs'Q and 8) pivoted to the frame and provided with an arm is extending at right angles thereto near its free end, in which is mounted a friction roll K designed to encounter the lug f on the gear F when the latter is rotated. The upper end of the arm K bears against the end of the cutter bar J and operates the cutter bar to sever the wire fed through the channel grooves of the platform I when the lug f encounters the roll on the arm is. The cutter bar is returned to its initial position by the spring L, which bears against its opposite end.

Having indicated the several parts by reference letters the operation of the machine will be readily understood. Vii-e from one or more reels (not shown) is threaded through a corresponding number of guide tubes H to the crimping rolls '1), D and the machine started by shifting the driving belt from the loose to the driving pulley B. The rotation of the crimping rolls draws the wire through the guide tubes, crimping, it as it passes between the rolls; and it is then relivered into the channels in the platform I, and past the cutter bar J. )Vhen the cam ping lug f,

F on the gear F in rotating encounters the lug E on the lever E it forces the gear C against the action of the spring C carrying with it the portion C of the clutch mechanism, thereby disengaging it from the part C and stopping the further rotation of the crimping rolls and the delivery of wire past the cutter bar. When the cam F" passes the lug E the spring 0 again forces the clutch mechanism into interlocking engagement and the machine operates as before. )Vhile the crimping rolls and the wire are momentarily at rest the lug f 011 the gear F in rotating forces the swinging arm K out of 7 its line of travel by contacting'with the friction roll K on the swinging arm. This actuates the cutter bar J which shears off the wire projecting beyond it. Upon the lug f passing the swinging arm, the action of the spring L forcesthe cutter bar back to its initial position. The segmental cam F is so arranged with respect to the tripthat the clutch mechanism is thrown out of gear before the tripping lug actuates the cutter bar, in order that the Wire may be cut while at rest.

To provide for automatically cutting the wire into predetermined lengths, the cam F is made in segmental form that the length of the cam may be added to or reduced and the clutch mechanism thrown out of gear when a predetermined length of wire has been fed through the crimping rolls. The gear F is made interchangeable in order that gears of different diameter may be mounted in the slotted way 9 of the standard G. As the pickets are cut off they drop into a suitable trough or receptacle attached to the frame of the machine but not shown in the drawings.

\Vhen it is desired to make continuous criinped wire the gear F is removed, whereupon the cutter bar and the clutch disengaging mechanism cease to operate.
