LOOM FOR WEAVING RETICULATE REINFORCEMENTS.

To all whom 2'1 may concern Be it known that I, ROBERT M. JONES,"I

citizen of the United States, residing at Denver. in the county of Denver and State 5 of Colorado, have invented certain new and useful Improvements in Looms for \Veaving Reticulate Reinforcen'ients, of which the following is a specification.

My invention relates to looms for weay'ing l reticulate reinforcementsfor use in concrete structures and its object resides in the provision of a mechanism of simple construction by which metallic bars and wires may be woven into a reticulate article of either flat, cylindrical, or conoidal form. I attain.

this object by the mechanism shown'in the accompanying drawings in the various views of which like parts are similarly designated and in which, v

Figure 1 represents an elevation of the loom with the warps and filling of which the woven product is produced, in the operative position, Fig. 2 a fragmentary frontelevation of the same looking in the direction of the arrow A, Fig. 1, and Fig. 3 a

fragmentary plan view of the machine.

Referring to the drawings by letters, the

weaving-machine consists of a suitable base X upon which are erected an upright frame X for the support of the loom-harness and a the mechanism b which the same is operated, ;standards V for the support of a horizontal-shaft Y upon which the warp-reels A arefmounted, and standards which support the element of the mechanism by which the'relative position of the parts constituting the filling or weft of the woven product is determined and by which said product is shaped to the desired form.

The reels A are loosely mounted upon the shaft Y to more independently about the axis-thereof while the machine is in operation, they are spaced from each other to permit of a limited lateral displacement and they are each provided with an integral sheave-member T of reduced diamcter, to receive a rope or cable S one end of whlch is securely fastened upon the base X while weights U are suspended from their opposite ends after they have been placed over the respective sheaves, for the purpose of holding the warp tautand keeping the proper strain thereof while it is being paid off the reels.

The shaft Y has a longitudinal key way Specification of Letters Patent.

other and the reels are each provided witha corresponding key-seat A, so that by insertion of a key into. the way Y and the seat A of one 'of the reels, the latter may be, fixed on the shaft when it is desired to wind the warp upon the reel at thed'nitial point of the operation, which may be readily accomplished by rotating the shaft in its bearings .by any suitable means such as the' crank Y shown in Fig. 3 of the drawings.

The loom harness consists of the twoheda dle frames C each provided with a "plurality. of heddles E and respectively? attached at opposite sides of a pair of'endless ropes or cables I looped around two drums D which are mounted to rotate about horizontal axes in suitable bearings secured near the upper and lower ends of the upright frame X. The drums D are connect ed to rotate in unison, by means of endless] chains R which are placed around sprocket j "wheels Q secured upon the opposite ends of"? the shafts :D" of the respective drums and the upper one of these shafts carries in addition, a hand wheel H by means of which the two drums are rotated to alternate'the position of the heddle frames in the operation of the machine.

To prevent retrograde movement of the two drums, toothed wheels K are mounted upon the-shaft of the upper one adjacent the sprocket whee'ls and a series of double gravity pawls L of'difi'erent lengths are pivotally connected upon blocks secured to the frame X to engage the toothed peripheries of the wheels K at either side of the perpendicular passing through their center.

The element by which the rods comprised in the weft or filling of the woven product, are spaced and by which the said product may be formed into either a cylinder or a conoid, consists of a shaft B which is rotatably supported in bearings on the before mentioned standards W and upon which a series of disks J are fixedly mounted, The disks which, collectively, provide a drum or reel. upon which the woven product is wound, as will hereinafter be explained, are provided with equidistant peripheral notches which are placed in 'alinement for the receptioh of the rods F which constitute the web of the reticulate reinforcement.- When the machine is employed to wear: 1

reinforcements of cylindrical form the several disks comprised 'in the series, are of equal diameters, while when the loom 1s operated to produce a conoidal reinforcement, the disks are progressivelyxreduced in 'di- 5 ameter from the outer one at one end of the shaft B, to the opposite one at the other extremity of the same. The last describedarrangement of disks drawings.

I P which are rumed u'pon'the ends there- 'of and which carry series of overbalanced pawls N of diiferent lengths which respec-' tively engage the toothed peripheries of two ratchet-wheels M, fixedly mounted upon the shaft. Gravity dogs 0 pivoted onthe standards W are place in engagement with the teeth of the respective w eels M to prevent retrograde movement of the rotatory element and stops X adjustably' secured upon the u right frame X are providedto determine f t e extent of the movement-of the-levers P and,'in consequence that of the are through The warp of'the reticulate rein orcement prodiice'd by. the operation of the machine, consist'slof double wires which in the drawings are indicated by single lines G, and

so which are wound u on the reels A, and the web or fillingof a reinforcement is provlded by rods F which in the 'o' eration are placed in .thealinedperiphera notches 'of the dished...

B is intermittently rotated by means of,levers and laces strands are twisted together with the ends of the wires projecting beyondthe first rod to complete. e continuity of thmreticulate reinforcement," which in accordancewith the relative sizes of thedisks is either cylindrical or conoidal in form.

To produce a flat reinforcement, it is only necessary to withdraw the rods comprised m en ,the warp 1s,

the filling, from the notches in the disks after the latter have been partially rotated and it will be understood that by varying the perimetrical form of th disks the machine may be efiectively employed to produce reinforcements of quadrangular form. I c

'As the reels A rotateindependentl'y-on the shaftY, and are constantl restrained by. the geln'ent of the weighted cables 8 with the s eaves I, the saidreelswill, in
