To all whom, it may concern.-

Be it known that 1, JAMES W. BERRY, a citizen of the United'States of America, and a resident of Iowa'Oity,in the county of Johnson and State of Iowa, have invented a new and useful Fence-Weaving Machine, of which the following is a specification.

My invention relates to wire fence weaving mechanism, and the objects in view are to provide means for weaving mesh wires to. connect parallel cables, each mesh wire being coiled or twisted around each cable intersected thereby; to provide means for conjnnctively twisting two mesh wires on a single intermediate cable simultaneously with the twisting of single mesh wires on each of the outside cables; to provide improved means for reciprocating the mesh wire twisting apparatus, to carry the same from one line of cable to another; to provide improved means for intermittently rotating themesh wire twisting devices, whereby said devices are held from ro-' tation duringthe lateral reciprocation thereof;

to provide means for automatically control-Q ling the reeling mechanism to regulate the length of the meshes in the fence, and furthermore to otherwise improve and simplify the construction of the operating mechanism to produce an efficient machine of the class described.

Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the. appended claims.

In the drawings:-Figure 1 is a partial plan view of a fence machine embodying my invention. Fig. 2 is an end view to show means for operating the feeling mechanism. Fig. 3 is a rear view partly broken away on the line 3-3 of Fig. 2 to show the means for communicating motion to the shafts which carry the twisting devices. Fig. 4. is a vertical section on the line 4.-4-of Fig. 2 to show the mechanism for communicating intermittent reciprocatory motion to the shifting mechanism.

Fig. 16 is a detail View partly in section and partly broken away of the reeling mechanism, the section of the drumbeing indicated by the line1616 of Fig. 17 and line 16l6 of Fig.

2. Fig. 17 is a transverse section of the reeling drum on the line 1717 of Fig. 16. Fig. 18 is a detail view in perspective of a mesh wire twisting mechanism, showing the slides in dotted lines.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

The framework of the machine is indicated by the numeral 10 and may be of any preferred construction toprovide the necessary bearings for the mechanism as hereinafter described.

The main or driving shaft is indicated at 11 andvmay be provided at one end with a.

belt-pulley12, or with other equivalent means whereby motion may be communicated thereto. This main or driving shaft carries one member of a stop-mechanism, such member consisting of a mutilated gear 13, shown in detail in Figs. 7 and 8 and having-teeth upon approximately one-half of its periphery. The other member of said stop-mechanism consists of a pinion 16 fixed to a shaft 18 and having a smooth faced shoe 17 adapted to be presented to the mutilated gear during the time that the smooth portion of such gear is passing the pinion, whereby the contact of the shoe with the smooth portion of the mutilated gear holds the pinion from rotation Fig. 15 is g and hence maintains the twisting mechanism,

as hereinafter described, in a state of rest The shoe 17 is preferably attached to or formed integral with the side of the pinion 16, and the smooth portion of the mutilated gear is extended laterally or flanged, as indicated clearly in Fig. 8.

Parallel with the counter-shaft 18 is a series of tubular spindles 18, the bores of which are designed to serve as guides for the wire cables, and fixed to the rear ends of the spindles 18 and the shaft 18 are the chain-wheels 19 upon which travels, and which are connected by, the chain 2Q, said chain being held taut by the adjustable belt tightener 21. The chain 20 is carried alternately over and under the wheels 19, whereby the adjacent spindles are rotated in opposite directions. Fixed to the tubular spindles near their front ends are the fiat guiding webs 23, having reduced portions 23 which are adapted to fit between the contiguous edges of the upper and

lower slides

40 and 41, the thickness or vertical measurement of the saidwebs being approximately equal to the interval between the said contiguous edges of the upper and lower slides. These slides are provided with half bearings 43 which are equal in diameter to the width of the reduced portions of the guiding webs 23, whereby when the half bearings of the slides register the spindles 18 may be rotated, the reduced portions 23 of the guiding webs turning freely in the half-bearings. Mounted in certain of these half'bearings are the

hubs

26 and 27 of the

twisters

26 and 27, which are disposed respectively above and below the plane of the spindles 18. These twisters are provided with

flanges

26 and 27 to bear against the outer and inner sufaces of the

slides

40 and 41 to preventiongitudinal displacement, and mounted rotatably upon the spindles 24, which are secured to the twisters, are mesh-

wire spools

24 and 25. Mesh wire guides 28 and 29 are provided to direct the wire in its movement from the spools to the point of use.

In the construction illustrated in the drawings two of the above described twisters are mounted in each

slide

40 and 41, and by the opposite reciprocation of the slides these twisters may be arranged in pairs in conjunction with the spindles upon opposite sides of the central spindle, as shown in Fig. 5, or may be disposed as indicated in Fig. 6, in which two of the opposite twisters are arranged in conjunction with the central spindle, and the other twisters are arranged in connection with the exterior or side spindles. It is obvious that in whichever position the twisters are disposed the rotation of the spindles by the means described will cause a similar rotary movement of the twisters around the axes of the spindles as centers, and hence that the mesh wire spools will be carried around the cables which are disposed in coincidence with the axes of said spindles. The paying reels 22 are arranged horizontally in rear of a guide roller 22, which is disposed in rear of the chain wheels 19, to guide the cable wires to the twisting spindles.

Fixed to the main or driving shaft 11 is a second mutilated gear 14, forming one mem ber of a stop-mechanism for actuating the re ciprocatory slides 40 and 41, the other member of the stop-mechanism being a pinion 30. The mutilated gear 14 is provided with teeth upon approximately one-fourth of its periphery, and fixed to and carried by the pinion 30 is a double-ended stop plate 32 provided with concaved terminals which are adapted to engage the smooth surface of the gear 14, as shown in detail in Figs. 9 and 10, said smooth portion of the gear 14 being extended laterally to form afiange, as indicated in Fig. 10. The pinion 30 is fixed to a counter shaft 31 parallel with the main or driving shaft and said shaft carries at one end a disk 33 having a wrist-pin 34 which is connected by means of a pitman 35, to one arm of a rocking lever.

36. This lever is provided at opposite ends with pins 37 which are connected respectively to the upper and

lower slides

40 and 41 by means of

pitmen

38 and 39. The number of teeth on the mutilated gear 14 is sutficient to turn the pinion 30 through one-half of a revolution, and therefore the stop-plate 32 checks the motion of said pinion and hence of the shifting mechanism at the end of each half revolution of the pinion. Therefore the rocking or shifting lever 36 swings from the position shown in Fig. 5 to that shown in Fig. 6 during one movement of the pinion and then back to the position shown in Fig. 5 during the succeeding movement of the pinion, and each movement of the pinion occurs during one complete revolution of the mutilated gear. By means of this mechanism the

slides

40 and 41 are alternately moved from the position shown in Fig. 5 to the position shown in Fig. 6 and then back to their original position, at intervals regulated by the speed of rotation of the main or driving shaft. During the time that the slides or shifting

bars

40 and 41 are at a rest, with their half hearings in registration, motion is communicated by the main or driving shaft through the countershaft 18 to the spindles of the twisting devices, andthe mesh wire spools are carried around the cables one, two or more times according to the relative number of teeth on the

gears

13 and 16. When the parts of the twisting mechanism are in the position shown in Fig. 5 two mesh wires will be twisted around each of the intermediate cables upon opposite sides of the central cable, and when the parts are in position shown in Fig. 6 two mesh wires will be twisted around the central cable and one around each outside cable.

The reeling mechanism receives its motion through a counter shaft 45 which is connected by

gears

44 and 15 with the main or driving shaft, a crank-arm 46 fixed to the said counter-shaft, a pitman which is adj ustably connected to the extremity of said crank-arm, a

rocking lever 48, and a second pitman 49, or by any other equivalent combination of devices to suit the particular location of the reeling mechanism.

The reeling mechanism comprises a drum the body portion 21 of which is loosely and removably fitted upon a shaft 52, to which it is keyed as shown at 5 6, this key being removable to allow the body portion of the drum to be detached from the machine when filled. An operating lever 51 is loosely mounted upon the extended spindle of the drum, and is bifurcated to embrace a ratchet wheel 53 which is fixed upon a sectionally angular portion of the spindle, said lever carrying a multiple pawl 54: for engaging the teeth of said ratchetwheel to communicate motion from the lever to said wheel. A similar multiple pawl 55 is employed to prevent return movement of the drum. A split-pin 60 is engaged in a transverse perforation in the extremity of the shaft 52 to hold the lever in place thereon,andthe bearing box at the oppositeend of the drum is preferably provided with a removable cap,

of any preferred construction, to facilitate the displacement of the shaft to allow the detachment of the body portion of the drum. Slidably mounted upon a reduced sectionally angular portion of the lever 5i is a sleeve 50 to which the adjacent end of the pitman 49 is pivotally connected, and projecting from said sleeve is a bracket 58 carrying the roll 59,

which is adapted to bear upon the surfaceof the fence as it is reeled on the drum and thus shift the pivotal connection of the pitman 49 toward the outer end of the lever, or from its fulcrum, as the completed article is accumulated, whereby the throw of the lever is gradually reduced in extent to preserve a uniform tension upon the fence.

It will be understood that in practice various changes in the form, proportion, and minor details of construction may be resorted to without departing from the a principle or sacrificing any of the advantages of this invention.
