T0 all Vwhom t concern: f

vBe it'known that I, MARSHALL B.;Liio,rn, a citizen of the United States, and a resident of Menominee, county of. Menominee, :and State of Michigan, have. invented a certainf` new, usefuh and V`Improved Reed-Weaving Machine, of which ification..

- My Ainvention relates generally .tov` ma-l chines .for producing woven -reedfarticles, but relates more: particularly to machinesv kfor producing reed articles which embody a frame-asa part thereof. The term reed., fabric, ashere used, means a fabric com,`

posed' of spaced stakes which are relatively rigid and over and under which relativelyfleXible fillerstrands are woven, and-it. in-u.` cludes both the natural. reed, fibre reed, and materials having the. general characteristics l of reed. y y

The general' object of my invention is to provide a machine whereby the production of woven reed articles having frames may be simplified and expedited.

I aim alsoto providea machine whereby reed fabrics can be woven directly upon the'V frame of the article, atleast in part, thereby eliminating a number fof steps hitherto thereof` extending downwardly intov grooves incident to the manufacture of such articles, also resulting in the ability to produce suoli articles' more rapidly and at .a lower cost."

My invention consists generally in mecha. nism of the form, arrangement and co-action of the parts thereof whereby the above named objects, together with others-that will Yappear hereinafter, are attainable; and my invention will be more readily understood by reference to the accompanying drawings.

which illustrate what I consider at the present time, to be the preferred embodiment thereof. v I

In said drawings, "Fig.f1` is side elevation of a machine embodying my invention.

Fig. 2 is a perspective view of an article frame with the stakes secured therein. 1

Fig. 3 is the topview of a machine shown in Fig. 1, the' fabric being omitted bett-er to 'disclose the'construction of the machine.

In the `drawings vI havechosen to vdepict tlieffproductionof. a babyv carriagehood, Y vbut this it ,shouldbe understood isvby way of villustration and not` by way :of limitation.- Ababy carriage hood is usually composed o-f a plurality ofbow shapedwooden members, generally circular in cross section and which divergefrom. a common point, the amount of'di'vergence depending upon the size or character'of the hood ,to be produced.

f In .Fig.r2, 1 represents one of the hood yframe members and suitably secured therein,

inspaced relation, will be found aplurality 'l of stakes 2.'.k VIt is over and under the stakes duced.

The Uv-shapedY frame member 1 with 'the stakes attached thereto is placed in the ma- Y 2 tliatthe filler strand is to be woven to thev lend that `azwoven reed fabric may be pro#v chine about to be'described with thev stakes adapted *tov receivev them. rlhe machine, with the article frame member'1 therein and with a portion'of the fabric'produced is shown in' elevation in Figure 1. The endl portions of 3 3 Vof the frame 1 eXtend'into openings formed in the upper portionsy of standards 4 4 that constitute part of the frame 'of the machine. These standards4 4 4 areA rigidly fixed to a suitable base not shown.

' Mounted in brackets 5 and v6 "carried 'by thel standards 4 4 willbe found shafts 7 vandi 8 respectively, the shaft'S havingy a` wheel 11 i thereon vwhich* is provided with av plurality The shaft 7 is station- 6. Keyed to the shaft 8 so that it rocks therewith' -is a substantially rectangularly shaped4 plate 13 which' is yprovided along three of its edges with`v gear .teeth'forming Vthe gear rackv14.--Secured;to the plate 13 plurality of grooves 17 of such size and so spaced that they are adapted to receive the stakes 2 before referred to. As will appear Y shortly, in operation the stakes are moved into and out of the grooves 17. Surrounding the plate 18 and somewhat beyond the plane of the stakes will be found a frame portion 18 which, in plan, is U-shaped. The frame 18 terminates in the end portions 19 that are fixed to the shaft 8 so that any movement of the shaft 8 causes corresponding movement of frame 18. 1n the frame 18 there is mounted a plurality of blocks 20, one for each stake of the article to be produced, which blocks are slidable to and from the plane of the stakes. Each block 2O is provided with a guide portion 21 fitted in frame 18 to ,guide the block in its slidingd movement. Each block 20 is also provided with a somewhat vertically disposed tgroove 22 adapted at times to receive the stakes 2, which block 20 is furthermore normally pressed toward the center plane of the stakes by means of a spring` 23. A spring 2-1 tends to press a pin 25 toward the central plane of the stakes. This pin 25 it will be understood is adapted to project directly into the stake receiving grooves 22 the purpose of which will appear hereinafter. It will be understood that all the blocks 20 are of like construction so that the description of the one just given will suffice for all.

The plate 18 furthermore is provided with a T-shaped slot 2 the path of which is substantially U-shaped (see Figure 3). A roller Y 27 operates therein, the roller being' attached to the upper end of a depending frame member 28. To the lower end of the frame member 28 there is secured a reel 29 on which the filler strand 30 is carried, the filler strand 30 passing upwardly through the hollow portion 31 of the frame 28. The upper end of the portion 31 terminates in a shuttle-shaped portion 82. the operation of which will appear shortly. The frame 18 is embraced by a bracket member 33 which is secured to move with the frame 28. The bracket 33 is provided with a U-shaped portion 34; which slidably engages the frame 18 and carried upon a bracket 35 will be found a filler strand packing wheel 36. For actuating' the packingl wheel 86 there are a number of pins 87 which are mounted in the frame 18 and which stand upright therefrom.

There remains yet to be described the mechanism for projecting' alternate stakes from Atheir normal plane to form a shed for the reception of the filler strand. mechanism is mounted upon a bracket 38 This carried by the frame 28. Upstanding from the outer end of the bracket 28 is a stud shaft 3S which in turn is surrounded by a sleeve 10 the upper end of which terminates in an elliptical cam portion 41.. Surrounding` the cam portion 111 will be found four radially movable jaws 4-2, 13, t and a5, the jaws 42 and 18 being' diametrically opposite and the if and P5 being' diametrically opposite. The jaws l2 to 15, inclusive, are provided with curved outer faces L16 to 19, inclusive, which, when the blocks are property positioned are adapted to engage the stakes and cause projection thereof from their normal plane for shed forming purposes.

rThe jaws y-1-2 to 45, inclusive, are arranged for sliding movement in the upper portion 50 of the wheel 51 which in turn, has gear teeth 52 which mesh withthe teeth of the gear rack 14. The gear wheel 51 is keyed to the sleeve 4G so that Vrotation of the wheel 51 causes like rotation of the sleeve 40 cam L11 and sliding' jaws 12 to 415, inclusive. The jaws 4:2 and 43 are pulled toward 'the center of the cam by means of the tension sprinp- 53 and the jaws L14 and 41-5 by means of the tension spring 54. They are thus kept in Contact with the outer' face of the cam 11, two thereof bein T always positioned along the major axis of the cam and two along the minor axis. 1t is thought that the remaining features of the machine will be better understood by a description of its operation.

As before stated, the article frame 1 with the stakes 2 secured therein is placed in the machine, the end portions 8v of the frame being passed through openings in the standards 1, as is well shown in Fig. 3. The frame 1 follows the U-shaped form with the machine and the stakes extenddownwardly, normally entering the recesses or slots 17 in the housing, part 16 of the plate 15. 1n starting` the machine it Vwiil be understood that the frame 18 is relatively close to the frame 1 of the hood.- The filler strand 30 is pulled through the end portion 32 of the filler strand inserting means and is suitably passed under one or more stakes. Thereafter, the operator grasps the frame 28 as by means of either or both of the handles 55, 56 and thereby moves all the mechanism connected therewith. This movement causes rotary movement of the jaws 4t2 and 45, inclusive, and assuming-1 that the direction of movement is as shown in Fig. 5, the jaws 1-2 and 4:3 will engage alternate stakes pushing them from their position in the grooves 17 of the housing part 16 and into the aligned openings 22 ofthe blocks 20, As the shuttle-like portion 82 moves along itl represses, successively, the blocks 2O in order to make way for its passage. As soon as the shuttle-like portion 32 has cleared a given blocky 20, thefstake 2 is restored toy its normal plane 'under the action of the thrust pin257 which` is moved' by' the spring 24.` vThe liller f ver 60. l f

strand. 30 is thus intertwined with' the stakes -in .the presentV instance passing over one stake and: under the next. vNot. only is 'the liller stra-ndi guided into place,`but itiisalso lproperly positioned-or packed, relative to tliefiller strands of pre-formed fabric. @This isr accomplished. by means ofthe packing wheel 36 whichis actuated by engagement with the pins 37, and which has an angularly disposed lface so that in its rotary movement it engages successive portions of the filler strand and moves the saine upwardly into place. It will be. understood. that the mecha'- nismismoved the necessary distance in one direction and. then reversed and moved the requisite distance in thek other direction, which alternate movement. r1s maintained vuntil all the fabric desired'i's produced# It should also be understood that when'y one course of filler strandis inserted' the whole mechanism is swung downwardly the, thick! ness of one. :Killerk strand in order that the neXt coursemay be accommodated. Before swinging the mechanism downwardly a distance equal to the `thickness of one filler strand, a pawl 64 on the shaft 7 adapted to beV actuated 'by a handle 63, lis released from` engagement with onen of the teeth on the wheel 11'. A downward pressure is then ei;- erted on. saidv mechanism and the pawl 64 is then` Aengaged with the Lneat tooth 12 to hold 'i the mechanism in proper position for inserting the next filler strand. In the article underk consideration the filler strand is notin the yfirst instance, passed from one end of the frame to the other, because this is notl at: af-ll necessary, inasmuch as the mechanism canbe reversedV at any desiredl point.l

lVliilermeans may be providedv for the automatic reversal, of the. parts, manual means are herel shown.` When the iller'strandfinserting` portion 32y reaches the end lof its travel in the direction shown in Figf, the n position yof theI packing wheel 36 is changedI by swinging it to `the positionv shown in- Fig. 4*, that is tosay, the bracket 35 is swung around to the opposite side of the 'portion 32. The nut 57 is loosened to permit the swinging movement and tightened to hold the bracket in set position. The 4next step p is -to change the position of the `jaw/S42 to 45, inclusive, from the position rshown vin Fig. 5 tothat shown in-Fig. 4. This is ac-` complished by swinging.- the bracket 38 from the position shown in Fig. 5 to that lshown in Fig. 4. This movement will rotate the gear wheel 51 so as tobringthe jaws 44 and 45 to their new` position lso that the swinging movement of the, cam only is necessary to thrust them .outwardly andvfpermit retraction of thejaws 42 and 43" under the -action ofspringi 53. To swingtlie bracket 38 lockfpos'itionfshow-n'in Fig. 4 and the `jaws 42 .and 43 are',l moved` inwardly, this by virtue lofthe shifting of the major and minor axes of theV cam. The springs 53 and 54 as vbefore stated, constantlykeep the jaws incontact withythe contiguous faces of the cam.

. After' having adjusted the jaws, .thel tapering pin58 is replaced. The machine is their ready forreverse movement.

The hood, orrother article beingproduced can thus be vquickly woven and the product when removed from the machine appearsv as in Fig. 7; Thereafter itis but necessary yto'avttachjthe remainder ofthe varticle frame, as indicated at 6l, if it is an article which requires an additional frame member. The

usual hood fixture will then be securedV as v indicated' at62 in Fig. 7.

Obviously articles of different forms may be produced by simply changing the contour ofthe machine, i.` e. the path that the filler strand inserting means follows.

vvThe many advantages of my machine will be understoodby thoseY skilled in the artl to whichv this appertains without further comment. It -might-be stated, however, that while lin the machine here Ydisclosed the .frame that .carries the slidable members is arranged -with swinging movement away is held',"it should be obvious that if desired, vthe machinecouldreadily beiformed so that 'movement Vaway from vthe position of the articlevframe would Vbe uniform. That isl to say,vthat the frame could readily be ar-v ranged for movement away from the article frame at right angles thereto.
