FENCE-MACHINE..

I SPECIFICATION forming part of Letters Patent No. 649,598, dated May 15, 1900.

Application filed September 22, 1899. Serial No. 731,329. (No model.)

T0 al?, whom t may concern;

Be it known that I, HENRY A. Dn CHENNE, a citizen of the United States, residing at Sorento, in the county of Bond and State of Illinois, have invented a new and useful Fence- Making Machine, of which the following is a specification.

This invention relates to fence-making machines or looms of the manually-operated species having mechanism for regularly twisting wire strands or runners around inserted pickets or slats and particularly intended in the present instance to produce continuous or extended fencing for after application and also equally well adapted for constructing panels of predetermined lengths to be subsequently secured in selected places.

The aim of the invention is to divest this class of machines as much as possible of all mechanical contrivances and superfluities and at the same time avoid the least detraction from their efficiency by such depletion,

but on the contrary effectually increase their practicability and insure a more positive and advantageous fulfilment of the desired end, to afford means for acquiring convenience in operation and adjustment by adjacently positionin g the respective mechanisms for these purposes, and thereby require but one operator to successfully control the entire device, to construct and arrange the twisters in such manner that they may be readily changed in position, depleted or supplemented by other similar parts to vary the elevation or number of strands or runners on the pickets or slats without involving a material separation or readjustment of bearing devices or supports and conjointly therewith effect a particular actuating leverage organization in operative relation to reciprocating devices for simultaneously and uniformly rotating the said twisters, and to supply such other incidental attachments to the minimized structure as are necessary and contributory to the materialization of a complete machine of the nature set forth.

Generally stated, the invention consists of a frame provided at one end with a number of adjustable reels on which are wound cornpanion strands or runners to be fed through shiftable twisters freely and removably interposed without bearing-support between opposite reciprocating operating-bars embraced by a slotted lever having reversely-extending upper and lower connections lnovably atl' tached thereto and respectively to upper and lower portions of the said opposite bars, a winding shaft or spindle being located at the other end of the frame. to receive the conipleted fence fabric. y

The invention also consists of the distinct arrangement of twisters between opposite 'operating-bars Without axial support or other analogous bearing and free to be vertically adj usted by loosening the upper ends of said bars and employ therewith vertically-adj ustable reels to permit a variation in the elevation of the strands or runners on the pickets and also accommodate an in crease or decrease in the number of said parts.

The invention further consists of the arrangement of a series of twisters operated by opposite reciprocating bars combined with a slotted lever embracing the' latter and having movably-attached connections on both sides of its fulcrum extending above and belovv the lever and respectively attached to the upper' and lower portions of the said bars, whereby an alternate pull-and-push influence is exerted on the bars in accord with the elevation or depression of the lever. i

The invention further consists of a tension device of a continuous non-differentiating character for the reels and having spaced edges contiguous to and engaging the rims of the said reels, thereby forming a continuous tension-resistance irrespective of the vertical elevation of the reels and conformable to any number of the latter without adjustment or other extraneous manipulation.

The invention furthermore consists of the details of construction and arrangement of parts hereinafter more fully described and claimed.

The preferred embodiment of the invention is illustratedin the accompanying drawings, but is subject to such variations in dimensions, proportions, and minor details of construction as fully lie within the purview of the invention or would not cause a sacrifice of any of the advantages of the same, and wherein- Figure l is a perspective view of a fencemakiug machine incl udiug the features of the IOO invention. Fig. 2 is a longitudinal vertical section taken through the center of the machine. Fig. 3 is la transverse vertical section through the twisting-frameand adjacent parts of the main frame. Fig. 4 isa detail perspective view of the uprights, reciprocating bars, operating-lever, and twisters of the twistingframe shown on a larger scale and parts in operating position in full and dotted lines. Fig. 5 is-a detail perspective view of the operating-lever. Fig. 6 is a similar view of the tension device.

Referring to the draw-ings, wherein similar numerals are employed to indicate corresponding parts in the several views, the numeral 1 designates the main frame, consisting of longitudinal sills 2, having teeth 3 extending along the greater .portion of their upper edges and connected at opposite ends by closely-arranged pairs of cross-'ties 4 and 5,

thesills and ties being held slightly elevatedv by base-rests 6. Between and by the ties 4 a winding-'frame is supported, and consists of uprights 7, attached to each other at the top by'a cap-piece S, in which a vertically-disposed winding spindle or shaft 9 has bearing, and also in a lower block 10, located about centrally of the said ties 4. On the spindle or shaft 9, above and resting on the cap-piece 8 isa ratchet-wheel 11, adapted to be retentively engaged by a pawl 12,1novabl y attach ed tothe cap, and the upper end of the said spindle or shaft terminates in a crank-handle 13.

The ties 5 rigidly support a reel-frame 14, comprising opposite uprights 15, with alined apertures 16 therein and connected at their upper en'ds by a cap-piece 17. In this frame a series of reels 1S are adj ustably mounted bymeans of elongated removable bearing-rods 19, tted in transversely-alined apertures 16 in the opposite uprights 15 and also projected through said reels, the latter having end rims or anges 20 for lan evident purpose. The reels can be elevated or lowered or their number increased or decreased to change the location or vary the number of the strands or runners on pickets or slats of one length or accommodate dilferent sizes and kinds of pickets. A metallic or other suitable strip 21 has'its opposite ends secured to the cap 17 and outermost cross-tie 5, and Vthereto is fastened asecond strip 22. These strips have their inner edges slightly spaced apart and in such position as to receive the rims or flan-ges 20 at one end of the reels and institute s'uieient frictional pressure or tension thereon to prevent too loose movement or rotative play. This tension device extends in a vertical direction the full length of the reel-frame,

sion device specified does not ofier the least resistance to such operations, and a further advantage is derived by having the tension non-differentiating or uniforln on all the reels.

A twisting-frame is adjustably positioned in the main frame and consists of opposite guides 23, closely arranged against the inner sides of the sills 2 and connected at the ends by upper and lower cross-strips 24, having their free terminals extended over above and below said sills. Intermediate of the guides 23 are fixed a pair of spaced cross-supports 25, and to the uppermost crossstrips 24, inside of the line of teeth 3 of each sill, are secured longitudinal ties 26, which have suitable journal-bearings 27 therein for rotatable reception of a transverse shaft 2S. this shaft toothed wheels 29 are keyed and mesh with the teeth 3 of the sills 2, andat one end a crank-handle or analogous device 30 is also attached to said shaft for im parting a rotative movement thereto. Rising fromV the supports 25 are uprights 3l, united by upper, lower, and intermediate transverse bracestraps or similar devices 32, arranged in `pairs and with said supports serve to maintain a regularityv of space between the uprights.v Between the Vupper and lower brace-straps tween them to permit the rack-bars to be adjusted, as will be presently set forth. The inner edges of the rack-bars 34 are toothed and actuate or rotate interposed twisters 35, having opposite fianged ends 36 and intermediate circumferential teeth 37, all integrally formed, and each twister is provided with a pair of apertures 38, extending entirely therethrough from end to end. The teeth ofthe twisters and rack-bars are in close mesh at all times when these parts are in operative relation and the twisters hold the rack-bars apart equally, the initial construction and arrangement of the uprights 31, brace-straps 32, and antifrictional rollers 33 being proportioned and determined in such manner as to insure On the ends of The intermediate Y straps 32 have no antifrictional rollers be-v IOO IIC

their necessary contiguity and obviate a jam or any tendency to a detrimental binding.

An operating-lever 30 is employed to actuate the reciprocating rack-bars 34 and in its organization embodies a slot 40. This lever could be produced in a variety of structural ways, but the form shown is preferred. A handle 4l is located at one end and thereto are secured opposite bars or straps 42, .embracing the uprights 3l and rack-bars and united at the farther ends by a space-block 43. The slot 40 is thus provided between the end of the handle and spaceeblock and is large enough to permit the lever to have full operative movement vin a Vertical direction. The fulcrumf44 of this lever is supported by the intermediate brace-straps 32 and consists of an interposed block 45 between said straps which serves as a means for holding a fulcrum-pin 46, made fast to the bars or straps 42 of the lever. This fulcrum is centrally positioned between the rack-bars 34, so as to equalize the throw of the lever in opposite upper and lower directions, and it will be noticed that the said rack-bars also freely move between the bars or straps 42 on reverse sides of the fulcrum 44. The lever is connected to the rack-bars by reversely-extending pairs of links 47 and 4S, the links 47 being projected upwardly, one on either side of the one upright 31 and movably attached to the rackbar 34 nearest the handle 4l. The other pair of links have a downward projection and likewise embrace the other upright 3l and are movably secured to the rack-bar a greater dist-ance, from the handle of the lever. The upstroke of the lever will push the rack-bars 34 in opposite vertical directions and a downstroke will pull said bars in reverse directions. The uprights 3l, straps 32, and antifrictional rollers 33 are removably bolted together, and the upper devices of this character are particularly easily disconnected and assembled to allow shifting or adjustment of the twisters or supplemental additions and decrease in the number used. By loosening and disconnecting the upper straps 32 and rollers 33 the rack-bars 34 can be spread apart a greater distance by reason of the absence of any obstruction between the intermediate straps, and the twisters 35 can then be moved closer together or farther apart, and as the upper ends of the said bars are open additions to or depletion in the number of twisters can be accomplished, and after attaining the desired adjustment or addition or reduction in number the bars are restored to normal position and the upper straps 32 and antifrictional rollers 33 assembled. At the time the twisters are changed in vertical elevation or number the reels 1S are correspondingly elevated or depressed and their number augment-ed or depleted.

The handle 4l of the lever 39 and the crankhandle 30 of the shaft 28 are comparatively close together on the same side of the main frame, so that one operator can readily reach both and control the operation of the entire machine.

To prevent the reel and winding frames from being drawn inwardly or warped by the longitudinal strain of the strands or runners, a spreader 49 is employed and comprises parallel longitudinal bars 50, connected a short distance inward from their ends by trans- Verse stop-bars 5l and 52, the unsecured portions of the ends of said bars 50 being adapted to rest on the cap-pieces 3 and 17 and so that the stop-bars 5l and 52 have their outer edges in close engagement with the inner edges of the said cap-pieces. This spreader is removable to make the rack-bars 34 accessible, and to hold it in place under ordinary conditions keepers 53 are secured to the stopbar 5l and adapted to slip under the cappiece 8 to obviate displacement, especially during the winding operation of the spindle or shaft 9.

To prepare the machine for operation, companion strands or runners 54 are Wound on the reels 13 and the number to be used placed in the reel-frame 14 at the desired elevation and degree of separation under the control of the tension device. The rack-bars 34 are then loosened at their upper ends and spread apart to receive twisters 35, corresponding in number to the reels and arranged in alinement with the latter, and the strands or run-y ners from each reel are next threaded through the twisters and attached to the spindle or shaft 9 by a slight Winding thereon. The twisting-frame is adjusted or moved over the sills 2 by rotating the crank 30 in the proper direction and through the medium of the toothed wheels 29 and teeth 3 on the sills adjacent the winding-frame leaving suflicient Space to insert the preliminary pickets or slats. The twisters 35 are 110W regularly rotated to twist the strands or runners around successively -inserted pickets or slats, and during such operation the twisting-frame is gradually fed away from the winding-frame. After a certain length of the fence has been completed or woven the spindle or shaft 9 is rotated to wind said fence-section thereon and simultaneously draw out the strands or runners for a repetitions operation and which will become contiguous proportionately to the length of the said strands or runners. In making short lengths of fence or regularlysized panels the strands could be either first severed and wound on the reels or cut at regular intervals after the complete insertion of the pickets and again attached to the working parts where necessary. In either event the operation of the twisters is especially advantageous. The parts are so timed and limited in movement by a predetermined calculation that an alternate full depression and elevation of the lever 39 will rotate the twisters iirst equallyin one direction to secure an inserted picket or slat and then in a reverse direction around a succeeding picket or slat, and by this means the intercepting twists of the strands or runners will be unil rm and regular. The twisters are also held in their adjusted positions by the strands or runners threaded therethrough and will not rise or fall between the rack-bars and at the same time undue friction between the rack-bars and twisters is prevented.
