SPECIFICATION forming part of Letters Patent No. 504,984, dated September 12, 1893.

Application tiled January 19, 1893. Serial No. 458.897. (No model.)

To all whom it may concern,.-

Be it known that I, ALvA L. KITSELMAN, a citizen of the United States, residing at Ridgeville, in the county of Randolph and State of Indiana, have invented a new and useful Wire-Fabric Machine, of which the following is a specification.

This invention relates to wire-fabric ma-v chines; and it has for its object to provide certain improvements in machines of this character, whereby, while securinga machine which will be efcient in operation, at the same time is comparatively inexpensive and easy to operate.

To this end the main and primary object of the invention is to provide a portable fabric-making machine, which can be readily 2 is a central vertical longitudinal sectional view of the same. Fig. 3 is afront elevation of the machine showing the position of the spool bobbins. Fig. 4 is a view similar to Fig. 3 showing the bobbin devices removed, and also the front board or plate of the machine removed. Fig. 5 is a detail vertical sectional view on the line wof Fig. 3.

Fig. 15 is a small detail view showing two forms of fabric which are preferably manufactured. Fig. 16 is a detail modification. Fig. 17 is a detail sectional View of the modification. Fig. 18 is a detail in perspective of one member of the twisters having a retaining flange.

Referring to the accompanying drawings, A represents the frame or casing of my improved fabric making machine. The frame or casing A comprises the oppositevertical side strips a, .between which are arranged the front and rear bearing boards or plates B. The bearing boards B, and the opposite side strips a, are suitably braced and connected together by means of the upper and lower pairs of connecting strips b, so as to hold the framework rigid, while at the same time providing a simple casing to inclose the main working parts of the machine. At this point it may be noted that the Width of the boards B, is less than the space between the opposite side strips ot, in order to leave between the opposite edges of said bearing boards and said side strips vertical guides or ways bx, for the accommodation of shifting slides N to be hereinafter particularly referred to and described.

The bearing boards B, are provided with a vertical series of circular bearing openings C, the bearing openings in one board being in alignment with .the corresponding openings in the opposite board, in order to provide a perfect bearing for the twisting devices of the machine, and from the bearing openings in said bearing boards lead the shifting slots c. The shifting slots c, are arranged out of line with each other in vertical series, as is clearly illustrated in the drawings and` for the purposes hereinafter set forth, said slots being designed to provide means for shifting the weaving devices from one set of openings to another, as will be well understood by those skilled in the art.

The vertical series of bearing openings C, in the bearing boards accommodate and form bearings for the vertical series of intermeshing twister wheels D which are thus mounted to have a rotation on their axes while in re1- atively xed positions. The said twister wheels D are preferably made sectional and comprise the separate superposed hollow members d, Which,when aligned with each other, are designed to have their outer edges snugly register with the circular bearing openings in the bearing board, and their outer faces flush with the outer faces of such boards so as to not interfere with the free movement of the shifting devices employed in the machine. Each member or half d, of the twister wheels is provided with the oppositely disposed and parallelsquared notches or slots E, cut in from opposite edges of the disks forming the members or halves, and arranged in substantially parallel planes, the squared notches or slots of each section or member being designed to align with the corresponding notches or slots of the opposing members, so as to complete a single twister wheel having notches or slots let in from opposite sides of its periphery and parallel-with each other. The relative position of the notches or slots E to each other in the twister wheels, may be clearly understood from the fact that one notch or slot in a twister wheel is designed to align with one of the shifting slots leading from the bearings in which the wheel moves,while the other notch or slot aligns with the other upper or lower, as the case may be, shifting slot leading from the same bearings in which such wheel moves. Now with this general construction in mind, the other features of the twister may be referred to. Each of the sections d, is provided at its inner edge with the cog `flange F, which is designed to rest flat against the corresponding flange of the opposite section or member, and the teeth of the meeting cog flanges are preferably out of line with each other, or in staggered arrangement, so that lost motion will be prevented by the teeth, meshing therewith, skipping the notches or slots E. The inner meeting edges of the twister sections d, are provided with the notchesf, which receive locking lugsf, in the opposing sections, and one of said locking lugs is further provided with a projecting lip f2, projecting beyond the notch in the opposite section, so as to prevent the two sections slipping out of alignment I with each other, and one of said sections is also'further provided with apinf, which is arranged opposite the lip f2, and serves as an auxiliary stop to prevent the twistersections from slipping outof alignment on that side. The sectional construction just described can be slightly modified as illustrated in Fig. 9 of the drawings, in which the twister wheel is a single piece or casting having the notches or slots E, as described, but instead of the two cog flanges, has a single central peripheral cog flange F. Although I have described this modified construction, nevertheless the sectional construction is preferable owing to the fact that I not only securelightness, which is quite desirable, but I also secure a staggered arrangement of teeth to prevent lost motion.

The vertical series of twister wheels D, are arranged one above the other in any desired number, at the option of the manufacturer, and the cog tianges of each wheel intergear or mesh with the corresponding cog flanges of the wheels above and below the same, so that all of the twister wheels are rotated simultaneously, and therefore provide means whereby the notches or slots E, of the several wheels can be simultaneously aligned with the shifting slots in the bearing boards.

Now having determined the specific construction of the twister wheels, and the speciiic manner of connecting the same together to provide for simultaneous movement, we will next consider the means for imparting motion to the same. The central, or any convenient, twister wheel is further provided on one of the sections thereof outside of the cog flange with a supplemental bevel cog ring G, the outer edges of the teeth of which are a distance in from the outer edge of the twister wheel section on which it is formed, so that such bevel cog ring can be arranged inside of the bearing board adjacent thereto, while at the same time allowing the portion of the vtwister wheel beyond the teeth to still have its bearing in the board. This construction does not interfere with the shifting devices to be described. At one side of the twister wheel just described, which may be quite properly termed the drive twister wheel, the front bearing board is provided with a slot H, which is designed to receive a portion of the bevel pinion h, which projects therein and meshes with the bevel cog ring of the twister wheel so as to impart motion thereto. The bevel pinion h, is mounted on one end of the stub or crank shaft h', journaled in suitable bearings h2, and has connected to the other end thereof the crank handle h3, by means of which the shaft can be readilyturned by the operator. As motion is communicated to the said crank shaft, it will be readily seen that simultaneous motion will be given to the entire vertical series of twister wheels.

The squared notches or slots E, in each twister wheel areydesigned to accommodate lthe flattened ends I, of .the shifting spool or bobbin carrying arms J. The arms J, are made in suitable lengths, and are provided at their iattened ends with the opposite shoulders j, which are disposed on opposite sides of the twister wheels, so that the said arms are prevented from being withdrawn therefrom, and at the opposite ends of the arms are arranged the right-angularly disposed jour- IIO nals j', on which are mounted the wire spools or bobbins K. The said wire spools or bobbins K, carry the weft wires used in weaving the fence, and the tension ot'` said spools or bobbins, to check the feed thereof, is conveniently secured by means of the tension spring la, clamped against one end of the spool or bobbin, as clearly indicated in the drawings. The liattened ends of the arms J, which rest in the notches or slots of the twister wheels are further provided with the opposite perforated guide lugs L, through which the weft wire passes and which serve as guides for leading the wirethrough the twister wheels and entirely independent thereof, said twister wheels being alone provided with the central Wire perforations M, extending entirely therethrough, and accommodating the longitudinal Stringer or warp Wires aroundV which the wetts are twisted.

In connection with the spool or bobbin carrying arms, it is well to observe that the vertical width of the flattened ends of the arms .l is equal to the depth ot' the notches or slots in the twister wheels, or at least the portions of said notches or slots which work in the circular bearings for the wheels, so that the edge of the circular bearings, in the bearing boards, serves to hold the spool or bobbin carrying arms snugly in the twister Wheels while the same revolves and thereby prevent any lateral play or wabbling. (See Fig. 12.)

, It is now thought that the general operation of the machine will be apparent. It was stated that each alternate twister wheel accommodates two of the wire carrying devices at the same time, except the top and bottom wheels, which at each alternate twist carry one of the wire carrying devices asis clearly shown in Fig. l of the drawings.

In order to provide for weaving the wet' wires from warp to warp,or for forming a diamond shape fabric as shown in Fig. l5, Iemploy certain means for shifting the spool carr ying arms alternately from one twister to another at each alternate operation, and these means will now be described. Arranged to reciprocate or slide between the opposite edges of the bearing boards and theopposite side strips a, within the vertical guides or ways bx, are the oppositely moving shifting slides N. The shifting slides N, carry at their inner upper ends the racks n, which mesh with opposite sides of the upper spur wheel n. The upper spur wheeln, is journaled in the upper ends of the boards B,and provides means whereby the two slides are reciprocated simultaneously in opposite directions, and one of said slides carries at a suitable point a second rack bar O, with which meshes a` suitably arranged operating toothed segment o, controlled by the handle lever o. By moving the lever up and down, the segment o, causes the slide directly behind the same to move in one direction, while through the medium of the upper spur wheel n', an opposite movement is imparted to the other slide as will be clearly understood. Secured to both sides of each of the shiftingslides N, are the arm shifting plates O'. The arm shifting plates O, are secured at their Vouter ends to said oppositely reciprocating slides, and are each provided with the extended arms o2, disposed at about right angles to the attaching end of said plates, and provided with a squared or circular shifting notch P, which is designed to embrace the portions L of the spool-carrying arms projecting beyond each side of the twister wheels, so as to provide means whereby the spool carrying arms can be shifted from one wheel to another, and also to close the shifting slots connecting the several bearings, so that as the twisters revolve, the spool carryingarms are confined thereinbetween the notched arms of the shifting plates secured to the opposite shifting slides. When the notches in the shifting plate arms are made circular as clearly shown in Fig. l1, it will be seen that the edges of said shifting plates will `form auxiliary bearings for the projecting ends ot' the spool carrying arms, so as to take the wear oft of the bearing openingsalthough it will be quite apparent that a squared notch provides shoulders whereby the raising and' lowering of the spool carrying arms can be more easily eected. The shittingplates are so arranged, that in one operation whenlthe weft is not beingtwisted on the upper and lower wires, such plates stand directly opposite to` each other to form pairs embracing the projecting ends of the spool carrying arms of` every alternate twister wheel. Asthe position of the slides is changed, one shifting plate on each side is carried to the upper and lower twisting wheels, as is indicated in dotted linesf in the drawing Fig. l2. i

Now it is thought that the operation of weaving a wire fabric will be apparent to those skilled in the art. Assuming` that the machine is to weave the weft wires, carried by the spools, in diamond shape onto the longitudinal warp wires passing centrally through the perforations in each twister wheel, we have the shifting plates arranged directly opposite each other embracing the projecting ends ot' the two spool carrying arms in every alternate twisting wheel, except the uppermost and lowermost. In this position by causing the twisting wheels to turn as described, the weft wires are twisted on every alternate warp wire except the top and bot tom wire. After this twist, the shifting lever is grasped, and the spool carrying arms, by means of the shifting plates, are` carried out of the twisting wheels inl which they were first revolved, and into the other alternate twisting Wheels which werein therst instance inactive. This shifting also carries one spool carrying arm into the uppermost and lowermost twister wheels, so as to twist IOO IIO

positions in the other twisters.

' the runner ends.

the weft onto the upper and lower wires of the fence or fabric. It is of course understood that when the twister wheels are turn ed so that their notches align with the slots between the wheelv bearings, each spool carrying arm of each twister wheely is carried into a different wheel, one arm being taken up into the wheel directly above While the other arm is carried below into the lower wheel, and as the weaving proceeds are shifted back and forth. By omitting the longitudinal warp wires between the upper and lower wires, a diamond-shaped fabric is manufactured similar to that shown in Fig. 15. This will be clear to those skilled in the art.

In order to provide for introducing the spool carrying arms into the twister wheels and working the same into their proper positions, the bearing boards are bored with the filling perforations Q, from which lead laterally into the upper and lower bearings, the slots q. By means of these filling perforations or openings and the slots leadingtherefrom, the fiattened ends of the spool carrying arms can be inserted into the uppermost and lowermost twister wheels and worked into their proper The spool carrying arms can be taken out in the same manner.

The machine just described is of course especially adapted to manufacture a standing line of fence and is if therefore necessary to provide means for moving the same along as the weaving proceeds. In order to provide for this, the machine is mounted on the adjustable slide runners R. The runnersy R, are curved upwardly and inwardly atieach end and are adjustably connected la't one threaded end by means of the binding nuts r, to the lower ends of the opposite side strips or to the body of the machine itself, while the other extremities of the runners pass through the opposite perforated end of the stationary shaft r', and are adjustably held therein by vmeans of the set screws r2, passing through opposite ends of said shaft and impinging on The advantages of such an attachment of the runne? will be apparent from the illustration of F g. 14, in which it is shown that the runners are capable of an outward swinging movement so that they can adapt the machine to hills, and by spreading out or contractin both of the runners, the machine can be raised or lowered as may be required. Parallel brace rods S, are connected to a suitable point of attachment above the center of the machine, and are connected at their lower ends to the stationary shaft r', between its ends. Said brace rods S, are provided with lower curved ends s, which extid above and follow the curvature of the chain wheel T, loosely mounted on the shaft r. The said chain wheel T is provided with a ratchet face t, at one side, against which is normally pressed the operating pawl lever t. The perating pawl lever t', is held against gri p on the ratchet, but also prevents any slip whatever. A chain U, engages the upper portion of the chain wheel and is anchored a suitable distance in advance of the machine, to provide for the propulsion of the machine as well as to regulate the mesh of the fabric being woven. Now it will be seen 'that the chain and chain wheel serve important functions. By, moving the pawl lever back and forth, the machine is not only propelled or dragged along, but at the same time the mesh of the fabric being woven is regulated by the play ofthe pawl lever. The pawl lever plays between the fixed stop V, connecting the brace rods at a suitable point above the chain wheel, and the adjustable regulating stop bar W. The regulating stop bar W,is provided with perforated ends sliding over the lower curved ends s, of said brace rod, and in close proximity to the top of the chain Wheel, and is held in any adjusted position by means of the set screws w, passing through the ends thereof and impinging on the brace lod. By adjusting this regulating 'stop bar, the play of the pawl lever is thereby lengthened or shortened, so that the drag of the machine is lengthened or shortened in order to regulate the length of the mesh of the fabric being woven.

In a modification illustrated in Figs. 16, 17, and 18 it will be observed, that if found necessary, I shall provide means for preventing the bearing boards spreading away from the twisting wheels held therein by reason'of the necessary twisting strain. Suchy spreading, in high machines, would likely occur and therefore loosen up the bearings, because the bearing boards are practically provided with a vertical slot from near their upper to their lower ends. To secure this result certain of the twister wheels are provided at one side of the cog flange with a circular retaining or strengthening rib X, interrupted of course at the notches or slots, and adapted to work inside of a corresponding groove fr, in the inside face of the bearing boards and concentric with the bearing openings therein.

Although the machine herein described is specially adapted for runninga line of woven wire fence, still it is just as capable of use in the factory or shop in any suitable position for weaving wire fabric for all uses, therefore adapting the machine to stationary indoor use, and I will have it understood that changes in the form, proportion and the minor details of construction may be resorted to without sacrificing any of the principles of my invention.

Having thus described my invention, what IOO IIO
