SPECIFICATION formi g part of Letters Patent No. 256,794, datedtfiApril 18, 1882 Application filed October 4, 1ss0.' (No mode1.)

' To all whom 'it may concern:

.Be it known that we, MAURICE GONVERSE and FRANK ROADY, of Cleveland, in the county of, Guyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Making Barbed Fence-VVire; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the [0 art to which it pertains to makeand use it, reference being had to the accompanyingdrawings, which form part of this specification.

Our invention relates to machinery for barbingfencc-wires; and it consists in the features and combinations hereinafter specified and claimed.

.In the drawings, Figure 1 represents our device in side elevation. Figs. 2, 3, 4, and 5 are detached and detail views, illustrating the barb 2o bending and applying mechanism in the various stages of its operation. Fig. 6 is a view showing the pinching-fingers and their associated parts, logetherwith the stationary cutter.

.A is a frame or table of any suitable construction, dimensions, and material for carrying and accommodating the various partszof our machine. 7

B is the main shaft, to which driving-power 0 is applied in any suitable way. Upon themain shaft B are placed four cams, one cam, O, suitably constructed to impart a reciprocating motion to the bent lever O, which is pivoted to the frame A. One arm of this lever 5 C engages with the cam O, and the other is connected by a link, 0 with a lever, 0 which is also pivoted to the frame A, as indicated.

' Upon the link 0 is carried the anti-friction guide-pulley C The function of the appara- 4o tus as thus far specified is to take up the slack of the wire as it is delivered from the barbing and feeding mechanism, and in the interval when the delivery of barbed wire from the said mechanism hasceased to give up the slack to 5 the spooling and twisting mechanism.

Heretofore when a spooling apparatus has been used with barbing mechanism in which the main or strand wires are fed intermittently the spoolhas been obliged to conform itself to the intermittent feed, revolving rapidly while" the barbed wirejs delivercd from the barbing mechanism and; stopping when the delivery ceases. To etfectthe intermittent spoolin g the spool has been revolved through springs or friction-bearin gs, whereby it is allowed to come stopping obviously strains and produces wear in the machine, and obviously, also, it is not conducive to the regular and uniform winding of the barbed wire on the spool.

3 By means of the automatic take-upbefore referred to, the spool-in g apparatus is rendered independent of the intermittent delivery of the wire from the barbing mechanism, the take-up controlling the slack, so that the spoolin g apparatus is supplied continuously and uniformly. As shown, the cam O is so shaped that the slack is rapidly taken up during the jfeed, (corresponding to the quick movement ;imparted to the feed-wheel F, as hereinafter explained,)' and is given up more slowly during the barbing= operation when the wire is -stationary, the incline w operating the levers G G to take up the slack, and the incline w, which is less oblique to the plane of rotation of theeam, returning them. is led in the manner shown in thedrawings over apulley, G at the free end of the lever 0 thence under the pulley 0%, out to the spooling andstrand-twisting mechanism.

The next cam, D, upon the main shaft is designed to actuate the barb-wire-feeding mechanism, and this cam is constructed to impart to said barb-wire-feedin g mechanism a prompt feeding motion and a return motion, which may be either slow or fast, as desired.

Themechanism actuated by the cam D may be described as follows:

D is a bent lever, pivoted at its angle to the frame A. One arm of this lever engages with the actuating-cam D, and has imparted to it a reciprocating horizontal motion, which is converted into a reciprocating vertical motion at the opposite arm of said lever. To this oppo- The barbed wire v site aim is attached. a link, Dflwhich passes up and connects with a one-way clutch device, D The clutch 1) may be constructed in any of the many well-known ways, so that the barbwire L will be grasped and fed down with each downward movemcntof said clutch D but will. be permitted to slip through said clutch on its upward movement.

To enable barb-blanks of different lengths to be fed and sever d, adjusting-holes D in the levtr D are provided.

By coupling the link D into the adjustinghole nearest the pivotal point of the lever D the'elutch mechanism D will be given its shortest feeding motion, whereas if the link D is pivoted to the extremity of the arm of the lever D the clutch and barb-wire-fceding mech anism will be given its maximum feeding movement and the barb will be fed and severed. The cam- D is to be adjusted upon the main shaft B in such a manner as to impart to the barb-wire-feediug mechanism its motion and operation in proper concert with the other parts of the machine in the manner and to the efl'eet hereinafter described. 7

' The next cam, E, is for imparting alrintermittentreciprocating motion to the pinchingfingers that hold the strand-wires in position while the barb is being fed and applied. This mechanism consists of a lever, E,of the third order, pivoted to one end to the frame A, e11- gaging at its middle portion with the cam E, and'jointed at its upper end to a link, E thus connecting the lever E" with a head-block, E This headblock moves horizontally upon suitable fixed guides, E and carries the pinchingfingers E The arms of these fingers are associated with one or more springs, E, that exert acontinuous pressure tending to open said fingers. The arms ot'the fingers E from the point pr their intersection and pivotal attachmentto'the head-block E have their outside surfaces diverging rearward. These fingerarmsmove between stationary pins or lugs E which operate, as the head-block E moves forward, to bring together the finger-arms, and thus clutch thestrand-wires in the manner and for the purposes hereinafter to be described.

As the head-block E recedes the springs E will openit'he pinching-fingers and permit the bar-bed wireto pass through. The'cam E is to be adjusted upon the main shaft B in such a manner as to impart motion to the pinchingfingers in proper concert with the operations of the-other parts of the machine, as will hereinafter be described.

The fourth cam,F, upon the main shaft B is for imparting an intermittent rotary motion to the feed-wheel F. The connect-ion between the cam F and feed-wheel F is more to be compared to a worm-gear than otherwise, as the point of said cam F engages with pins or teeth F and as said cam is revolved its impingement against the sides of said pins or teeth imparts to the feed-wheel F an intermittent rotary motion. This cam F is so constructed and adjusted upon themain shaft B as to impart to the wheel F a feeding motion just after a barb has been applied to the strand- G is a gear-wheel placed upon the main shaft B, which meshes with and drives the barb severing and applying mechanism.

Before describing the specific construction and operation of the device for severing and applying the barbs, we shall specify the concert of action between the various parts of our machine.

We will suppose a barb to have just been applied to the strand-wires by the barbing mechanism yet to be specified. When the barb is applied the clutch D through the influence of the cam D, raises to a height equal to the length of the barb-blank, and ready upon its downward motion to clutch the barbwire and feed a blank forward to be bent upon the strand-wires. At the same time the pinching-fingers E recede and open, and the cam F i imparts a quick feeding motion to the wheel F. This operates to draw the strand-wires through the machine a length equal to the distance between the barbs. the clutch D descends and feeds a proper length of barb-wire. pinching fingers move forward and grasp the strand wires to hold them in proper position and relation during the application of the barb. After the barb is applied the operation just described is repeated.

Having now set forth the construction, operation, and concert of action of the parts actuated by the cams G D E F, we will now proceed to a description of the barb-applying mechanism and its operation.

As the main shaft B is kept in constantrotation, it will be evident that the barb-applying mechanism is also kept in constant and even revolution, and this feature of a constantly-revolving barb-applyin g apparatus is, so far as we are aware, novel with this our invention, and it constitutes a very important feature- 0f our device.

For the sake of convenience in the specification and claims hereinafter following, we shall refer to the barb severing, bending, and applying apparatus collectively as a harbinghead, and this barbing-head, with its various component parts, is illustrated in Figs. 2, 3, 4., and 5 of the drawings. It may be described as follows:

H is a stationary earn fixed upon the end of a stationary shaft, H, around which loosely revolves the gear-wheel G, driven by the wheel G. The shaft H is hollowed or channeled to admit of the passagelongitudinally through it of the strandwires K. These strand-wires emerge from the face of the barbing-head through two apertures, K, located in the center of the face of the stationary cam H, as indicated in Figs. 2, 4, and 5 of the drawings. The

office of the cam H is to impart a hammering or pressing motion 'to the barb-bendingfinger- At the same time the When this is accomplished 1 too bars Rfor the purpose of firmlyhending and applying thebarb I1. to the strand-wires K.

Rigidly attached toor formed with one side of the gear-wheel G is a plate or disk, M, which of course revolves with the gear-wheel G. Upon the face of theplate M is fixed a revolving shear-blade, N, for severing the barbblank. Pivotally attached to this disk M are two levers, 0. One end of these levers impinges against and is operated by the stationary cam H, and is held against said cam by suitable springs, O. Thelevers O are pivoted at O to the face of the disk M. To the outer end of each of the levers O are adj ustably attached the bending finger-bars P. These finger-bars are attached to their respective levers O by the slot and set-screw connection indicated in the drawings. It will be evident that as the disk or plate Mis revolved around the stationary cam H the levers 0 will be rocked twice upon their pivots at every revolution of the disk M, and it is also evident that when the levers O are rocked or moved by the stationary cam H it will operate to bring together in a direction toward each other the bending finger-bars P, as indicated in Fig. 5-

of the drawings. The barb-bending fingerbars P are provided at their inner ends with grooved or notched noses P, as indicated in Figs. 2 and 3 of the drawings, and these noses are so constructed and relatively arranged that as a barb-blank, L, (see Fig. 2,) is fed to the barbing-head it will pass down, not only between the strand-wires K, but also between the bending fingers and noses P P. As this is done the revolving shear-blade N and the stationary blade .L (fixed to the standard N of the frame A) operate to sever the barb-blank in a slanting way, so as to point it. This slanting cut is effected by feeding the barbwire to the barbing-head ataslant, asindicated in Fig. 3 of the drawings, so that when the vertical cutting-blades N N sever the barbblank it will be at an acute angle to the longitudinal axis of the barb-wire. As soon as the barb-blank L has been severed the fingers and noses P P grasp it, and pressing upon its ends at opposite sides, as indicated in Fig. 4, begin to bend said blank around the strand-wires. Meanwhile the pinching-fingers E are grasping the strand-wires immediately in front of the point where the barb is being applied, so as to hold said strand-wires rigid while the finger-bars are revolving and bending the barb upon them. As the disk revolves, carrying with it the bending-fingers P P, the barb is bent around the strand-wires, as indicated in Figs. 4 and .5 of the drawings, and whenever the barbing-fingers are in a vertical position the stationary cam Hoperates to bring them together with a bending or pressing movement, (see Fig. 5,) which results in bending the barb closely and firmly upon the strand-wires.

. After a barb has been applied as just specitied the cam F operates to actuate the feedwheel F, the pinching-fingers relax their grip and recede, and the strand-wires are drawn forward, while the next. succeeding barb-blank,

as indicated in Figs. 2 and 3, is fed into the barbing-head to be severed and bent uponthe strand-wires in the manner already specified.
