WILLIAM GRIMM AND WILLIAM F. DREXLER INTERLOCKING FENCE COMPANY, OF MORT WIRE-FABRIC MACHINE.

To all whom it may concern.:

Be it known that we, WILLIAM GRIMM and WILLIAM F. DREXLER, Jr., citizens of the United States, residing at Morton., in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in VVire-Fabric 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 a machine for the Inanufacture of wire fence fabric, having for its object a twister support traveling in a continuous orbit, and to mechanism for feeding and depositing successively and continuously staywires in the said twisters.

A. further object of the invention is a twister frame mounted for continuous rotation, a series of rows of twisters revolubly mounted on the said frame, means for actuating the said twisters, and mechanism for continuously feeding a seriesof stays sidewise to present the same to the twisters, the said stays being formed previous to feeding and of length to reach from one outside twister to the other outside twister of the series and spanning the spaces between and engaged by the intermediate twisters of the seriesl The invention has for its further object twisting devices to which are adapted to be fed a series of longitudinal or running wires, and mechanism for feeding successively a series of stay-wires of suitable length to the said twisters, the said stays being formed previous to feeding and fed in a feed-way or guide conforming to the outline of the said stays.

A further object of the invention is a travcling frame, a series of twisting devices mounted for rotation in said frame, means for inaugurating the movement of the twisters at the same point in said frame, running wires adapted to be fed to the said twisters, mechanism for feeding a series of stay-wires to the twisters to be intertwisted with the running wires fed thereto, said mechanism comprising a feed-way or grooved frame, and a series of carriers adapted to receive the stays and deposit the same in position to be received by the twisters afore- Specification of Letters Patent.

said, and means for guiding the stays into the twisters.

The invention consists of a base frame, a revoluble frame mounted for continuous rotation in the base frame, a series of twisting devices Inounted in rows on the said revoluble frame and each row of twisters successively brought into action, means for inaugurating the movement of each and all of the twisters in-each row at the same point in the frame, running wires fed to the said twisters; stay feeding mechanism supported by the base frame, comprising feeders for moving in a step by step motion stay wires to each row of twisters asthey come into proper position, a reciprocating member adapted to engage and lower each successive stay to the revoluble frame and guiding means for insuring the deposit of the said stays in the twisters.

The invention is somewhat of the type as that found in an application for patent filed by Elwell, Grimm and Drexler, Jr., on the 21st day of March 1904, bearing Serial Number 199,129, wherein the revoluble or traveling frame, the twisters, and the driving means are similar; however as will be noted, it is preferred to employ more rows of twisters and have the rows of twisters correspond,

also to provide for the manufacture of a straight stay or square mesh fence.

The invention com rises details to be hereinafter more particullarly ointed out in the following specification, c aimed in the appended claims and illustrated in the accompanying drawings, in which- Figure 1 shows in side elevation, somewhat reduced, a machine embodying our improvements; Fig. 2 is a vertical cross-section, somewhat reduced, through the revoluble frame, and a longitudinal section through the stay feeding devices; Fig. 3 is a plan view, somewhat reduced, showing a general outline of our machine, with the twisters of the revoluble frame omitted; Fig. 4 is a vertical longitudinal section, through the revoluble frame, and the driving mechanism for the twisters located at each end 5 the figure also showing in dotted outline the twisters and their positions, and an end view of the stay feeding devices, with a stay outlined in black. Fig. 5 is a front elevation of a portion of the supporting frame, the feed-way for the stay-wires, and thereciprocating member for depositing the stays on the revoluble frame, Fig. 6 is a front elevation of a portion of the supporting frame, also a portion of the revoluble frame, and the devices and support therefor, for guiding the stays into the twisters of the said revoluble frame; Fig. 7 is a detached view in elevation of a support of the revoluble frame, Fig. 8 is an enlarged sectional detail showing a portion of the feed-way for the stay-wires, and a series of stays in position being fed forward to the revoluble frame; also the stay feeding mechanism, the means for depositing the stays onto the revoluble frame, a portion of the revoluble frame, and an edge view of a stay as the same is guided into the twisters 5 Fig. 9 is a detached view in elevation of the mechanism for imparting power to the twisters; Fig. 10 is a detail of the means for depositing a stay wire onto the revoluble frame 3 Fig. 11 shows an edge view of parts seen in Fig. 9 g Fig. 12 is an outline of a stay, showing its formation which is also the contour of the guide-way in which the said stays are fed; and Fig. 13 is a view of a portion of the fabric made by the machine herein referred to.

Like numerals of reference indicate corresponding parts throughout the figures.

The machine is built up of the side frame parts 1, being substantially of the design shown g however, these may be substituted with some other forin if desired. The forward ends of the frame parts 1 support a shaft 2 horizontally disposed, which is the preferred arrangement in this construction, with the opposite ends of the said shaft journaled in the boxings 3 of the frames 1. It is adapted to rotate the shaft 2 continuously, for purposes to be further described, the said shaft carrying a large gear wheel At on one terminal which meshes with and is driven by a pinion 5 on one end of a driving shaft 6 suitably journaled in the frame 1, and receiving its power from suitable mechanism, not shown.

The shaft 2, as will become apparent inthe further description of the machine, supports the twisting devices, as well as the mechanism for actuating the same during the continued rotation thereof.

On the shaft 2, at or near its opposite ends and within the frame, are carried and secured. thereto the heads or disks 7 constructed with the offset body portions 8, the outer edge of which forms a seat for supports or frames to be described. The supports or frames referred to consist of a series of pairs of flat bars 9. Each pair of bars is spaced. a short distance apart, while the adjacent pairs of bars are spaced a somewhat farther distance from each other, and the opposite ends of each of the bars seated on the edge of the off-set portions S of the heads or disks 7 and suitably secured thereto, see Figs. 2 and L1.

The bars are in all respects similar to each other, being provided with the ent-ont portions 1() at their opposite ends, and with the cut-out and slotted portions 11 and 12 at desired intervals intermediate their ends. rlhe cut out portions 10 provide for the dcpressing of certain parts to he described, while the eut out portions 11 are guide-vavs for fixed frame parts, and the slots 1; are wire grooves by means of which wires ma y he deposited into the twisters supported by the frames 9. 1n the drawings the wire grooves are shown at graduated distances, but they may be spaced at uniform distances if it is desired. To support the body of the frames 9 intermediate their ends we have provided the smaller disks or heads 13 having cut-out portions 14 at intervals in their peripheral edges in which the frames .(1 may he seated, see Fig. 2.

Disposed intermediate each pair of hars E) and at intervals coinciding with the grooves 12 therein, are carried twisters 15 of the slotted type, the slots of the twisters corresponding to the grooves 12 in they hars t) and serving as a means for engaging a wire or wires for twisting the same in the movement of the twisters. The twisters each have gear teeth and by this means are rotated, the same meshing with gears 16 carried h v short shafts 17 journaled in the hars E), and these shafts on one of their outer terminals carry the bevel pinions 1S meshing` with the beveled pinions 19 carried on driving shafts 20 paralleling the frames 9 and carried in the opposite heads or disks 7, the end of the said shafts also passing` through the heads and carrying thereon the pinions 21. The twisters 15 and the gears 16 are somewhat similar to those in the application referred to, the twisters being also -iournaled in the hars fr. and it is not thought that further description is here needed, as no specific claim is made upon the twisters nor their intermeshing gears 16, but upon the general arrangement and combination of the same together with devices to be described.

In the operation of the twisters it is aimed to inaugurate the movement of each row thereof at the same point in. the frame, imparting to the same an intermittent rotary motion opposite to the rotation of the frame. which supports the same, consisting of the heads 7, 13 and the bars E), the mechanism for operating the twisters being sueh that the twisters may have two or more revolutions imparted to them and then held in position to receive the wires to be fed thereto. This mechanism consists of cam-gears 22 disposed at opposite ends of the shaft 2 between the disks 7 and the frames 1, through which the shaft 2 passes, and the said cam-gears supported in a fixed position relative to the movement of the shaft and parts carried thereby, by means of bolts 23 or other suit- Cri loo

lli

able means. The disks 22 are provided with the off-set bodies 24, also the smooth peripheral cam-faces 25 and the segmentgear sections 26. The gear sections 26 at their outer ends terminate into the depressions a, and a', the former merging into the cam face 25 while the latter terminates' into a pair of ears a2, between which is carried a roller 27, the peripheral edge of which is of the same radius as the ears a2; and these ears upon the opposite side of the depression a merge into a depression a3 Awhich is of suitable length. The sections of gear 26 are separated by :an enlarged toothed depression a4 similar to the depressions a, and a and for a similar purpose, all of which will be explained.

To impart power to the shafts 20 through the pinions 21 and the gear sections 26, there is provided a series of gear wheels 23 which are in continuous mesh with the pinions 21, the same carried on short shafts 29, one end of which is carried in the head 7 and their outer ends in a ring 30 encircling and adapted to have a concentric motion, in the movement of the revolving frame around the offset portion 24 of the cam-gear 22, see Fig. 4. On each of the said shafts 29 intermediate the gears 28 and the rings 30 are carried the caminions 31, so called because of their pecu iar shape.

The cam-pinions are best seen in Fig. 9, which shows in elevation one of the end disks 7, the cam-gear 22, the short shafts or spindles 29 and the pinions 31, carried on the said shafts or spindles, and illustrating the manner in which the pinions 31 are retained in inoperative position, also the manner of imparting rotation to the said pinions during the continued rotation of the shaft 2 and the disks or heads 7. It will be shown that, in addition to the pinions 31 being rotated sufficiently to impart the desired rotation to the twisters 15v through the gearing described, the pinions 31, through suitable devices have an additional partial rotation imparted to them, to rotate the twisters a little more than is necessary to obtain the desired twist of the stay and longitudinal wires, so that as the twisted portions of the fabric or fence leave the twisters, the relax of the wires will not affect the same, but leave the twisted portions with the desired number of turns or twists to insure the interlock or intertwist which is desired, the form of which will be further described. The pinions each have the oppositely arranged toothed portions b, the intermediate enlarged tooth-shaped member or cam lug c, and the pair of tooth-shaped members or cam lugs d, similar to the lug c, which are upon opposite sides of a concave semi-circular depression e. At point a on the cam-gear 22 it is desired to inaugurate the movement of the pinions 31, and through the same and the gearing described, the twisters 15. ln the rotation of the shaft 2 and the heads 7, from a3 on the cam-gear to the point a, the lugs or teeth cZ-d are riding on the cam-surface 25 retaining the pinions 31 and the gearing connected therewith in a fixed position. As the pinions 31 ride against the upper gear section 26 the pinions are caused to mesh with the same; and the depression a serves to allow the lug d of the pinion 31 which is coincident with the same to have room to make the sweep in the rotation of the pinions. As the pinions pass from one section 26 to the other of the cam-gear 22, the lug or tooth c thereof engages the depression a4, which permits the further rotation of the said inion. where the pinions lleave the lower gear section 26, the depression e is causedv to engage and ride over the ears a2 and the roller 27 of the said cam-gear 22, im arting an additional partial rotation to t ie said pinion, as was above described; the depression a permitting the coinciding tooth d of the pinion to clear the section 26. During the continued rotation of the shaft 2 and disk 7 the tooth or lug c of each of the pinions is caused to engage with a roller 32, as seen in Fig. 9, which forces the pinions into a position Where the lugs or teeth d thereof will ride onto the cam-face 25; the depression a3 permitting the lugs or teeth d of the pinions to pass the edge of the gear as the same are partially rotated through engagement of the tooth c with the roller 32. The roller 32 is supported by a bracket 33 from the frames 1, (see Fig. 1).

From the above description it is believed that the operation of continuously rotating the shaft 2, the heads 7 and 13 carrying the frames 9 and the twisters 15, and the manner of im arting rotation tothe twister at intervals uring each complete revolution, will be clearly understood.

The stay feeding devices will now be described, showing how the stays are fed, also the means for directing and depositing each complete stay section into the twisters: Disposed with its forward end approximately above the center of the shaft 2 and the revoluble frame carried thereby, so as to allow the tops of the frames to pass beneath the same, is a guide-way or feeder 34, in width suflicient to permit of feeding a stay wire or Wires which are of length to extend from one outside twister to the opposite outside twister of the series. This feeder or guide-way extends back from thel revolving frame a suitable distance, then rises on an angle as at 36 and backward to the rear end of the frames 1, being supported at the rear end by the cross frame 35, as seen in Figs. 1 and The support for the forward end of the feeder consists of the bar or frame 37, the opposite ends of which are secured to the frames 1 carried At the point a" inwardly, then dropped down over the disks or heads 7 and across beneath the feeder, as clearly seen in Fig. 3.

The feeder or guideway is formed of two sections 38 and 39, the former being the lower and the latter the upper or overlying section, both of which are formed with matching U-shaped portions 40, the alternate Ushaped portions being inverted as shown, and coinciding with each of such U- shaped portions are run-ways or guides 41. The assembling of the sections 38 and 39 provides a sinuous passage-way having the alternately disposed horizontaleways 42 and the alternate connecting vertical ways 43. In Fig. 4 a front elevation is seen of the ends of the sections 38 and 39 when the same are in position, also showing in black outline a stay wire conforming to the ways 42 and 43 just described. 1t is required that the stays shall be formed in the manner shown, previous to being placed in the sections of the feeder 34, and they are placed in the same by inserting the body of the stays in the horizontal and vertical ways described, at the rear end, and beneath the covering plate 44, when the saine will slide down the incline 36 provided and enter the horizontal portion of the feeder and be taken up by a series of carriers and fed to the discharge end ofthe feeder and deposited in the twisters of the revoluble frame. These carriers consist of a series of link- belts 45 and 46, each of which is provided with a series of fingers or plates 45a, which in the movement of the carriers are adapted to engage with the horizontal portions of the stay-wires and in a step-bystep movement advance the said stays from where they enter the horizontal portion of the feeder, to the discharge end thereof. The carriers 45 travel in each alternate guide or run-way 41 around the front and rear sprocket wheels 48 and 48, which are mounted on the short studs or spindles 49 and 49, while the carriers 46 travel in runways or guides 41 intermediate the carriers 45, and around the front and rear sprocket wheels 50 and 50, carried on the shafts 51 and 52, which are disnosed in a vertical )lane beneath the spind es 49 and 49a. The said shafts 51 and 52 are carried across and beneath the feeder and journaled in a suitable manner to some suitable support attached thereto, but not shown.

The mechanism for imparting the desired motion to the carriers 45 and 46 consists of the following devices: On one terminal of shaft 6 is carried an eccentric 53, the strap 54 of which is provided with a tubular eX- tension 55 in which is carried one end of a rod 56, the outer end of which is pivotally connected to the outer end of an arm 57 which is carried on the outer end of the shaft 52 and the arm 57 has an off-set carrying a spring-held pawl 58 engaging the teeth of a ratchet-wheel 59 on the end of shaft 52, adjacent to the arm 57. The rod 56 is provided with a collar 60 between which and the end of the extension 55 en the said rod. is carried a coil spring 61 which permits the ratchet to have more or less movement under undue tension of the wires in feeding or in case of crowding of the wires during the feed, to prevent blocking of the mechanism or breakage of parts. The ratchet wheel 59 is retained in adjusted positions by means of the weighted pawl 62 pivoted to the side ol frame part 1, as seen in Fig. 1, in which hgure is also seen clearly the ratchet device above described. rl`he ratchet devices are slightly different from the well known form commonly used in shaping machines and like devices.

From the above description, it will be clearly seen that any motion imparted from the shaft 6 to the snaft 52 through the ratchet described, will impart a similar movement to the carriers 46, while at the same time a corresponding` motion will be imparted to the carriers 4o through a gear 63 on the opposite terminal of shal't 52 intermeshing with a gear 64, on. a counter shaft 65, which carries a series of gears 66, meshing with gears 67 on the said shafts or spindles 49. Through the carriers 45 and 46 a corresj'ionding movement will be iinparted to the upper and lower horizontal portions of the stays, and by reason of the series of carriers the stays may be bodily advanced from one end of the feeder to the. other, without the danger of buckling.

1n Fig. 8, an enlarged view is made to illustrate the carriers in the act of advancing the stays, also the means of depositing the saine onto the revoluble frame and directing the same into the twisters. Movable up and down in front of the discharge end of the feeder 34 is a plate 68, the rear face of which moves in juxtaposition to the edge of the feeder. rlhe said plate at its opposite ends is secured to duplicate plungers 69 movable up and down in guides 7() supported by the frame 37, see Fig. 3. The lower ends of the plunger-s 69 are provided with the cam-slots 71, which are adapted to be engaged by a series of pins or rollers 72 suitably spaced and secured to the inner faces of the heads or disks 7. The rollers are so spaced apart on the heads 7, that as one leaves the cam slot 71 of the plunger 69 the succeeding roller enters the same, the slot being of such contour that as the disks or heads 7 are rotated the plunger by means of the rollers described, and as seen in Fig. 10, will be intermittently lowered and raised, imparting` a corresponding movement to the plate 68 for a purpose i to be described. A guide-way for the plate 68 is provided, as 72, between the front edge of the feeder 34 and a stationary frame 73, see Fig. 8, the said frame 73, being supported by brackets 74 secured to the guides 70.

lll)

lll)

The plate 68 has its lower edge made in conformity to the contour of the stays with which it is to engage, having the depending portions 75, and intermediate de ressed or cut-out portions providing the horizontal engaging edges 76, and the vertical engaging edges 77. The portions 75 are adapted to engage the lowerhorizontal portions of the stays, and the edges 76 are adapted to engage the upper horizontal portions of the stays, while the edges 77 lie alongside of the vertical portions of the stays, when engaged by the said plate. As the stay wires are successively forced into the guide-way 72a, the plate 68 is lowered,

^ engaging the stays in the manner described,

and forcing them down, with the lower portions of the stays in position to be engaged by the upper edge of the forward frames 9 of each pair. 1When in this position, it is provided that the lower horizontal portion of the stays shall lie in front of the forward bars 9 of each pair, intermediate the slots 12, while the vertical portions of the stays are forced into the slots of the bars 9 and the twisters 15, which brings the upper horizontal portion of the stays adjacent to the face of the rear bars 9 of each pair, intermediate the slots 12 thereof, and alternately disposed with reference to the portions of the stays u on the opposite side of the said bars 9. Tlie devices for changing the angle or position of the stays, as they are deposited on the rotary frame, to deposit the portions thereof which are disposed vertically in the feed, into the twisters of the said frame, consist of a series of guide ) lates 7,8 and 7 9, being similar,r

and yet shape so that there will be no chance for the stays failing to be deposited into the twisters. The guide plates 78 are supported from the frame 73, having the beveled bodies 8() which adapt the lower horizontal portions of the stays to be engaged by the frames 9 and carried forward at an angle, as seen in Fig. 8; the plate 78 having the curved eX- tcnsions 81 which retain the forward portions of the stays in position until the same are engaged by the twisters. The plates 79, instead of having the beveled portions are carried down, straight, from the frame 73 to where they merge into the curved portions 82, seen in dotted lines in Fig. 8. The straight portions of the guides serve to hold the upper horizontal portions of the stays, during the changing of the angle of the said stays, to insure the engagement of the said stays by the twisters aforesaid, the curved portions 82 serving the same function as the portions 81 of the guides 78, being to retain the portions of the stays with which they engage, in position until the stays are firmly engaged by the twisters. The guides 78 and 79 or rather the curved portions 81 and 82 thereof, are adapted to be seated in the slots or cut-out portions 11 of the bars 9, as they are rotated into position Where they coincide with the guides aforesaid. In this way the stays may be forced down into the slots 12 of the bars 9 and also the slots of the twisters 15 and so held until the bodies of the said stays are within the grip of the twisters. Means has been provided for causing the twisters to uniformly grip the body of the stay-wires, so that there will be a uniformity of twist upon opposite sides of the center of the twist. This is accomplished by means of a series of lugs or pins 83 extending out from the face of the rear bars 9 of each pair, intermediate the slots in each bar, with which the bodies of the stays engage and are forced forward, until they lie in the twisters as desired. lt is preferable to have these lugs or pins 83 tapered or beveled, for in this way the end above desired may be the better reached.

The timing of the carriers with reference to the rotation of the twister frame is such, that a stay is forced into the guide way 72a and the plungers 69 depressed carrying with them the plate 68, which engages each stay, carrying the same into a position to be engaged by the frames 9 as aforesaid during the interval of moving the twisters the distance corresponding to the space between each row of twisters, when, by means of the guides 78 and 79, the stays are deposited into the twisters; the plate 68 having time to rise before another stay is projected into the guideway 72a as described, the rollers 72 being so positioned on the heads 7 that they do not depress the plungers and plate carried thereby until just previous to the twisters moving into a position to receive the stays.

It is preferable as shown to actuat-e the twisters from both ends of the frame, thereby obtaining more power; and while we have shown a stay having alternate right-angle portions, it is to be understood that the devices and feed of the stay may be modified to produce 'a still further form of mesh without departing from the broad principle herein outlined. Our aim is to provide a frame carrying twisters, which is adapted to travel in an endless orbit, and to provide means for feeding and depositing in a series of twisters in a row, stays which shall be engaged by all of the twisters of each row and intertwisted with longitudinal or running wires fed to the said twisters to form a square mesh.. The longitudinal Wires are fed in any suitable Way and from any of the Well-known devices, such as spools or reels. The fabric after the twisters have accomplished their work is drawn off from the under side of the revolving frame at some suitable point after the twisters have left the gear sections 26 of the cam gear, when the slots of the twisters are directed outwardly in a way to free the fabric, and place the said twisters in a position to again receive the stay as well as the longitudinal Wires to form the fabric.

Cit

From the foregoing description it will be understood that the operation of the drum is continuous and at intervals, or as each roW of twisters or Wire connecting devices passes the mouth of the stay Wire feeder, a stay, which has been advanced sideWise, is deposited on the drum to be engaged by the twisters or Wire connecting devices and that said twisters or Wire connecting devices are adapted to simultaneously connect portions of the body of the stay intermediate its ends to the series of intermediate strand Wires and the opposite ends of the stay to the selvage Wires.

The style of the fence fabric and the form of the intertvvist of the stay Wires with the longitudinal Wires, is substantially similar to that shown in Fig. 13 of the drawing.

lt is obvious from the foregoing that various changes might be made in the construction and arrangement of the machine Without departing from the principle and scope of the invention, and We do not Wish to be confined to the details as shown and described.
