FENCE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 417,279, dated December 17, 1889. Application tiled August 29, 1889. Serial No. 322,305. (No model.) i

' manufacturing that class of fences which are constructed of wire and wooden slats interwoven; and it has for its object to construct a machine of this class in which the necessity of inserting the slats or pickets endwise into the bights of the wires shall be dispensed with.

The invention consists in the improved construction, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved felicemaking machine. Fig. 2 is a longitudinal vertical view of the saine. Fig. 3 is a top view. Fig. 4 is a longitudinal sectional view of a part of themachine, showing the devices for forcing the pickets down into the bights of the wires in operative position. Fig. 5 isa vertical transverse sectional view .taken on the line o@ :r in Fig. Fig. (i is a perspective detail view of one of the twisting-heads detached from the machine. Fig. 7 is a detail view. I

Like numerals of reference indicate like parts in all the iigures.

1 designates a bench or table, which is mounted upon a frame 2, supported upon legs 3. The table 1 is provided with a vertical transverse slot 1, the front and rear sides of which have vertical segmental recesses affording bearings for the twisting-heads. The latter consist of segmental stems or shanks G, provided at their upper and lower ends with segmental heads or flanges 7 and 8, the former of which are provided along their peripheries with radially-extending teeth vor sprockets 9, and the under sides of the said upper anges 7 are provided with segmental grooves 10, adapted to engage segmental anges 11, formed upon the upper side of the bench or table adjacent to the recesses 5. The iianges 8, at the lower ends of the shanks 6 of the twisting-heads, are adapted to bear against the under side-of the bench or table. It will be seen by this construction thetwisting-heads are retained securely in operative position, the tlanges 11 engaging the grooves 10, and the flanges S combining to prevent the said twisting-heads from being dislodged. The twisting-heads in the oppositely-located recesses 5 5 are arranged concentrically, and are separated only by the longitudinal slot 4.. It follows that the said twisting-heads may be rotated in the bearings formed by the segmental concentric recesses 5 by means of suitable mechanism, which will be presently more fully described.

The twisters have been described in the foregoing as being segmental, and it should be added that they are to be less than full semicircular, since the segmental and less than semicircular twistersV leave an. opening as broad as the slot f1 in the table, through Which a picket may drop, as will be hereinafter described, whereas se micircular twisters would have to be separated by other means before they would allovirv a picket to drop through.

The heads 7 at the upper ends of the twisters are provided with upwardlyextending lugs or brackets 12, forming bearings for the spools 13, upon which is wound the wire 14, which is to be used in the manufacture of the fence. Each of the twisters is provided with a vertical perforation 15, through which the wire 14. is threaded,

1G designates a guide-roller, which is journaled in brackets 17 depending from the sides of the frame. At the rear end of the frame are provided bearings for a transverse roller 1S, upon which the fence is wound as it is being. delivered from the machine( i One of the side beams of the frame is provided on its inner side with a bracket 19, which, to-

" gether with the adjacent frame-beam, affords bearings for a short shaft 20, (shown in Fig. 7 of the drawings,) upon which is secured a ratchet-wheel 21.

22 designates a pawl attached to the frame and engaging the ratchet-Wheel to prevent reverse movement of the latter.

23 is an oscillating `frame mounted pivotally upon the shaft 20, astride the ratchetwheel 2l, and having at its uppe'r end a piv- ICO oted pawl 24, en gaging the said ratclietwheel. The lower end of the frame 23 is vconnected by a link or connecting-rod 25 with an arm or crank 26, extending from one end of a rock-shaft 27, which is jou rnaled transversely at one end of the frame. The opposite end of the rock-shaft 27 has a crank or handle 28, by means of which it maybe manipulated. It will be seen that by operating the rockshaft 27 an intermittent rotary motion may be imparted to the shaft 20. The latter is provided atits outer end which projects beyond the bracket 19 with a square post or projection 29, adapted to enter a correspondingly-shaped recess 30 in the end of the roller 18. The opposite end of the latter has a pintie 3l., adapted to be journaled in a bearing provided for its reception in one of the side pieces of the supporting-frame. The roller '18, as will be seen, may thus be connected detachably with its operating mechanism. The said roller is provided with transverse slots 32, in which tongues 33 are pivotally mounted. Y These tongues may be adjusted to a position transverse to the shaft, when they will serve to engage the pickets at the end of the fence and hold the latter from slipping as it is being wound upon the said receivingroller.

The bench or table of the machine is provided nea-r one end with bearings for a vertical shaft 34, carrying` at its upper end a sprocket-Wheel 35 and at its lower end a pinion 36, which meshes with the pinion 37 upon a counter- 'shaft 38. The latter extends through the front side of the frame, and cari ries at its front end a crank-wheel 39, by

means of which it may be operated.

40 designatesa chain running over the sprocket-Wheel 35 and engaging the teeth or sprockets 9 at the peripheries of the flanges at the upper ends of the twisters, of which latter tive pairs are usually to be employed,

although in the drawings hereto annexed only three pairs have been shown. At the end of the bench or table opposite to the sprocketwheel 35 is journaled a guide-wheel or pulley 41 for the opposite end ot the chain'40.

Idlers or friction-wheels 42 are mounted upon the bench of the machine to bear against the sides of the sprocket-chain interrnedially between the several sets or pairs of twisters. It will be seen that by this mechanism rotary movement lnay be imparted simultaneously to the several sets of twisters, the result bein'g to twist the previously-connected ends of the wires extending downwardly from said twisters.

A series of guide-rods 44 are arranged vertically on opposite sides of the vertical slot 4, the purpose of said rods being to guide the pickets used in the manufacture of the fence into the said slot. l a vertical gage-bar 45, and the opposite end of the Said slot is provided with a spring 46, attachedat the upper end of said slot and servin g to force the ends ofthe pickets against One end of the slot 4 hasthe gage-bar as they are being fed into the machine, thereby securingjuniformity in the position ot' the pickets with relation to the wires.

To the nuclei' side of the bench 1 adjacent to the front side of slot 4 is journaled a rockshaft 47, having arms `48, adapted to work in recesses 49, formed in the under side ot the bench and communicating with the slot 4. By oscillating the rock-shaft 47 in its bearings the arms 48 may be thrown in a forward direction across the. slot 4. The arms 48 are normally held in an upright position by the action of a spring 50 coiled upon the said rock-shaft. The latter is provided with a downwardly-eXtending arm 51, to which is attached 011e end of an operating cord or chain 52, which passes over a guide-pulley 53, and the other end of which is attached to a treadle 54, which is hinged to a bracket 55,

Vdepending from the front side of the frame of the machine.

To the under side of the bench in rear of the slot 4 is attached a series of guidebrackets 56, to prevent forward movement of the picket, which is being engaged and operated upon by the arms 48 of the rock-shaft 47.

In operation the ends of the wires, which are threaded through each pair of twisters, are first connected by twisting the same across the slot 4 directly at the lower ends ot' the twisters. A slat or picket is then dropped through the slot 4 until it rests upon the wires, when, by operating the rock-shaft 47 by means of the treadle 51, the said picket will be forced the required distance in a downward direction. By operating the crankwheel 39 a rotary movement is nowimparted to the sprocket-wheel 35, causing the chain 40 to rotate the several sets of twisters in their respective bearings, and thus twisting the wires above the slat or picket which has been inserted in the machine. The wires may be given one or more twists, as may be desired, andthe twisters will be stopped at a point where their inner straight` sides shall be in alignment with the sidesA of the slot 4. Another picket is then inserted and the operation is repeated until a suflicient length of fence has been made to enable it to be passed under the guide-roller 16 and attached to the winding-roller 18. rlhe latter may then be intermittently operated for the purpose of winding the fence until Va roll of the desired size has been formed, when the operation may be temporarily,suspended while the said roll is being removed.

The pickets from whichl the fence is being manufactured may be supported upon the frame of the machine in rear of the bench or table, or upon a shelf above the table, where they may be 'conveniently reached by the operator. y

My improved machine, as will be seen from the foregoing description, is very simple in its construction, and it may be 'manufactured at a moderate expense. To operate the ma- IOO IIO

chine rapidly and successfully, the services of but one man are required.
