Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filedMarch 4. 1903. $erial No. 146,211.

To all whom it may concern: 6 I I Be it known that we, PETER W. SoMMnR and Josnrn W. Sonnnn, citizens of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in WireBarbing Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to new and useful im provements in wire-barbing machines, wherein a machine for the purposes set forth is provided having improved devices for feeding, coiling and cutting the barbs; and the improvements are fully set forth and explained in the following specification and claims, reference being had to the accompanying drawings, and the numerals and figures of reference, making a part of this specification, in which:-

Figure 1 is a top plan view of the machine; Fig. 2 is a side elevation from one side of the'machine; Fig. 3 is an end elevation of one end of the machine; Fig. 4 is an elevation in cross-section of the wire feeding rolls and component parts; Fig. 5 is a sectional detail in plan of a portion of the mechanism associated with the feeding rolls; Figs. 6 and 7 show in partial section and elevation the intermittent gears for feeding the barb-wire; Fig. 8 is an elevation of the swinging cutter and the mechanism adapted to swing the same; Fig. 9 is an elevation from one side showing the coiling devices, and stationary and movable cutter; Figs. 10 and 11 show in plan parts of the coiling devices and cutting mechanism; Figs. 12 and 13 show in plan and in elevation means for guiding the barb-wire on the strand wire preparatory to coiling; Fig. 14 refers to three different sectional views of the coiling devices, as shown in longitudinal and cross-section. Fig. 15 is a plan view of one form of strand wire and barb formed thereon. Fig. 16 is a longitudinal sectional view of the part through which the barb forming wire is passed; Fig. 17 is a transverse sec tional view taken on the line .rx of Fig. 16.

Referring to the drawings 1 indicates a bed plate supported on the standards 2 at its corners. The bed plate has suitable cut out portions forconvenience in arranging the working parts of the machine.

3 indicates a driving shaft journaled in boxings 4 and on one end carries a pulley 5 which receives its power from any suitable source.

011 the opposite end of the shaft 3 is can'ieda bevel wheel 6 meshing with a bevel wheel 7 on an upright shaft 8. The latter is journaled in a boxing9 in the bed plate and carries on its lower end a bevel wheel 10 meshing with a bevel wheel 11 on a cross-shaft 12 journaled in the standards 2.

On the shaft 12 is carried a gear wheel 13 and a butterfly wheel 14; wheel 13 meshes with a gear wheel 15 carried by a cross-shaft l6 journaled in the standards 2 and the shaft also carried a butter-fly wheel 17. The wheel 15 meshes with a gear wheel 18 carried by a cross-shaft 19 journaled in the standards 2 and the said shaft carries a butter-fly wheel 20. These butter-fly wheels together with a butter-fly wheel now to be described journaled in a swinging frame constitutes the mechanism for guiding the finished barbwire to a twister and a suitable spool, when one or more strands are employed. The twister and spooler are not shown as they are of the usual construction and do not form a part of the invention herein.- The butter-fly wheel just referred to is indicated as 21 and is journaled in the upper end of a swinging support 22 pivoted at 23 to a stationary frame support and on the upper end of the support 22 is carried a roller 24 which is continuously engaged by a cam 25 on the driving shaft 3. (See Figs. 1 and 2.) The motion of the cam is to oscillate or swing the support 22 very rapidly which by means of the butter-fly wheel 21 intermittingly draws the strand wire with its barbs from the coiling devices. 7

26 indicates a spindle journaled in the boxings 27 on the bed plate and the said spindle is provided with a rectangular groove 28 extending from its rear end to a point adjacent to its front end and having the opening 29 in its front end as shown. The bottom of the groove 28 is provided with the wire groove 29.

30 indicates a stem or bar adapted to be seated in the groove 28 to reciprocate therein and the same has a coiling pin 31 extending forward of the end of the spindle 26 and through the opening 29. The end of the spindle 26 has the usual bevel face 32.

33 indicates a bushing in the end of the spindle 26 having a perforation extending through the same to coinicide with the wire groove 29, and the opening from the inner end of the bushing is beveled as at 34 and the bushing retained in proper position by the threaded plug 35. I

Slidably arranged on the spindle 26 is a sleeve 36 provided with the gear 37 and the tapered flange or cam 38. The sleeve 36 has a fixed connection with the bar 30 by means of the screw 39, so that any sliding movement of the sleeve 36 will be correspondingly imparted to the bar 30. The bar 30 is normally held with its coiling pin 31 extending out of the spindle 26 by means of a coil spring 40 around the spindle 26 and bearing against the sleeve 36 and a collar 41 as shown in Figs. 1 and 14. The spindle 26 and the coiling pin which it carries are continuously rotated, and during such rotation the coiling pin 31 is intermittingly reciprocated, by means of a gear wheel 42 carried on the shaft 3 meshing with. the gear 37, and the cam 43 forming a part of the gear 42 which at intervals is designed by its swelled or enlarged bevel face 44 to cause the sleeve to be shifted which will draw the coiling pin from its extended position, and the spring returns the pin after the cam has moved away from the flange 38.

The wire feeding devices for feeding the strand to coil barbs around the wire passing through the coiler,

and the severing devices will now be described. On the bed plate is carried a sheave wheel 45 journaled on a spindle 46, and the wire out of which the barbs are made is fed from a suitable supply around the sheave wheel 45 and through the guide 47, between two feeding rollers 48 and 49 carried upon upright spindles or short-shafts 50 and 51, and then through a guide 52, and means for guiding the wire over the strand to be formed into a barb by the coiling pin 31. These feeding rollers 43 and 49 are intermitt ingly rotated, adapted to advance only suflicient wire to form a barb and then stop and at the proper time be set in motion again. The mechanism for intermittingly rotating the feeding rollers, consists of a toothed wheel 53 on the upper end of the shaft 50 (see Figs. 1 and 4) engaged by the intermittent gear 54, arranged with peculiarly shaped engaged means for partially rotating the gear 53 and holding it stationary during the balance of the rotation of the gear 54. This engaging means consists of the cam pointed tooth a, on the face of the wheel 54 having the engaging point a and the cam teeth a (1 The wheel 54 is carried by and rotates with the shaft 3 in sucha manner that the teeth a, a a cause a partial rotation of the wheel 53 and with it the feeding rollers 48 & 49 while the wire is being fed and the said rollers 48 & 49 are held from rotation while the barb is being formed by the cam tooth a which engages between the two teeth of the wheel 53, and holds the same (see Fig. 6) until the tooth a again comes into proper alinement. To facilitate in the rotation of the shaft 51 the shaft 50 carries a pinion 55 on its lower end which meshes with a pinion 56 on the lower end of the shaft 51. The shaft 51 is eccentrically disposed in a sleeve or collar 57, and secured to said sleeve is an arm or hand operated lever 58, by means of which the feeding roller 49 may be shifted on its axis to bear closer to or away from the roller 48, to more or less tightly impinge awire fed between the two rollers, all of which it is believed will be. understood.

on the shaft 3; which during its rotation causes the cutter 62 to be oscillated and sever the barb as is apparent, and the cutter 62 is returned to its normal disengaged position by means of a spring 68 attached at one end to the plate 63 and at the other to a plate or bar 69 secured to the bed plate. A barb-wire guide '70 is provided having the bevel upper face 71 adjacent to the stationary barb-cutter 59 and is retained in position by the adjustable bar 7 2 having the threaded end 73 passing through the plate 74 of the bed plate and engaged by a thumbnut 75.

For convenience in describing the operation of the machine herein disclosed, we will assume that the dotted line A indicates a strand wire on which is to be placed barbs. The dotted line indicated as B, shows the wire from which the barbs are formed. The latter passes between the feeding rollers 48 and 49 in the manner stated, through an elongated opening 76 in the plate 60 or a component part thereof (preferably a component part as seen in Figs. 16 and 17) and is directed a short distance over the wire A by the guide 70 and the same engaged by the coiling pin 31 and wrapped around the wire A in the manner shown in Figs. 9 and 11. The instant the ceiling is completed sufliciently to leave the prongs of the barb, the cam 44 shifts the sleeve 36 in the manner stated reciprocating the pin 31 from the barb, and simultaneously. the cam 67 operates on the arm and causes the oscillating cutter 62 to do its work. During the ceiling, the feeding rollers are stopped, but instantly the cutters complete their work and the wire A moves forward to receive the next barb, the feeding rollers 48 and 49 are again partially rotated to bring another barb into proper position. for coiling, and the parts operated as just above stated.

It is understood that the ceiling devices and feeding means for the strand wire A may be such as to accommoda'te more than one wire, and we do not wish to be confined to the showing herein made, nor to the details and arrangement of the entire machine, as it is obvious that various changes may be made and details of construction resorted to without departing from the spirit and scope of invention herein.

Having thus fully described our invention, what we claim and desire to secure by Letters Patent of the United States, is:

1. In a device of the class described, the combination with barbing mechanism, of feeding rolls, one carried by an eccentrically disposed shaft, mechanism for shifting the axis of said earn eccentrically disposed, intermittent gearing' associated with said rolls for partially rotating the same and holding said rolls stationary at we determined periods, and severing devices, all substantially as described and shown.
