The hood is.

also transversely curved between the bows. The bow members as well as the side inembers 2O are formed of .l-shaped, or channel,

sections, see Figs. 9 and ll,v and .the bowmembers have flattened ends 22, seo Figs. 4 and 9, and are open intermediate the ends.

The edges of the reed fabric are received.

l firmly and permanently therein and in the shape imparted to the fabric. rlhe reed fabric is woven independently of the hood and is initially of generally vflat shape as shown in Fig. 3. TheA particular `fabric ,here shownl comprises the round stakes 24 and interwoven flat i'iller strands 26. Both the stakes and the strands are ineXtensible and the stakes are further apart than the strands. Both the stakes and the strands are of artificial reed, that is to say, they are made of paperstock, although such need'not neces sarily 'be the case. `While the filler strands 2G, here shown, are fiat, they can be round or of any other usual or suitable shape or construction common in the art.

:In the manufacture of the hood herein shown, a flat sheet of reed fabric of suitable dimensions is shaped. to provide the oppositelyl curved front and rear edges 2S, Fig. 3, which edges aie adapted 'to' lie within the front and rear bows of the con'iplcted hood.

Said curved edges in general lie across the stakes 24 and the ends of the stakes termi'- nate in said edges. The side edges 30, lying` between the curved edges, may be of any configuration and preferaby are straight and form the side edges of the shaped hood and lie between the bows and within the side members 20.

rllhe shape of the opposed edges 28 .is important.v Thecurves of the edges, for the symmetrical hood here shown, are identical and each has a low middle portion andlhigh end portions. The configuration is such that both the low, the high and intermediate portions are caused to lie in the saine plane, transversely disposed withr respect to thev fabric, when the fabric is shaped byV applying pressures Athereto `in a direction to flex the fabric 'across the edge and also in a direction to Hex it forwardly and downwardly toward `said edge; The bows are shaped during the fabric-shaping operation, and the fabric and bow-shaping steps are effected alternately; andthe fabric is securedkin' thel bow-member coincidently with the shapingof the bow member.

The shaping operations are carried out with the assistance of the machine shown in Figs. 4 and 5. Said machine comprises essentially a horizontal base plate32 provided with an upstanding anvil 34. A cam block 36 is mounted in front ofl and is movable toward and away fronrthe anvil and is guided in such vmovement by means Vincluding the posts 38 which are `carried by and upstanding above said .base plate and are received loosely in slots 40 of the cam'meinber. Said cam member is Vadapted'to be moved towards-the anvil and held releasably clamped against a straight bow member therein by a cam arm 42 ivoted on a post 44 in front of'said cam mem er. Said'cam arm is adapted to bear against a projection 46 of the'cain member and, when rotated in a clockwise direction, to force the Cain member toward the anvil and hold it releasablyvinadvanced position against the bow member faces Vrollers 52 which aie adapted to exert a pressure on a straight bow member and flex it into the shape of the cam member 36. Links 54 are pivoted to said handles and extend laterally therefrom and said links are also pivoted to other and forwardlyextended links 56 which have handle grips 58 attached thereto. Upstanding blocks 60 are swiveled on said links at the free endsv thereof and haveverticalvslots 62 therein in which flattened ends of the straight bow members are adapted to be received.

A flat spring Aplate 64 isA extended-from one block to the other and across the rollers 52 and the anvil 34and between said cani member 3G and said rollers and anvil. pressure of the rollers is adapted torbe eX- erted on said spring plate and through 'said plate to the bow member, thus to ilatten the channel of they bow member and compress its side walls upon .the stakes and strands of the Vreed fabric.v The `use ofl said spring plate distributes the pressure of thevrollers over the channelv member and gives a smooth contour 'to the bent bow member that. would The ico

iop

not be obtained without the spring plate/ since the roller otherwise would have a tent ency to bed into the channel between the incompressible stakes of the reed fabric ln forming the hood, the flattened ends of'a straight bow member 1i4 are inserted' in the slots62'of the swivel blocks GO so that the middle ofthe channel of the bowl member is opposite theanvil, as shown iniFig. 4. 'One of the curved edges of the fabric sheet 12 is inserted in the middle of the channel so vthat the'middle of the curved edge, or the lowportion thereof, occupies the middle of tlie'channel. The cam member 3G is thenfoiced up against the bow member and squeezes and compresses it against the anvil and flattens the sides of the channel, in the middle thereof, upon and into permanent clamping.engagement with vthe middle portion of the fabric sheet at the curved edge thereof, as is illustrated in y Figs. 5 and 6.

In this position,-the middle or low portion of the cui-'ved edge of the fabric lies lwithin the middle of the channel while the ends or high portions rof the curved edge upstand above' and outside the channel. Pressure is then exerted on one side ofy the fabric sheet, which upstands above the side of the channel, as for instance, the left side, to flex it` inwardly. and forwardly toward the cam member 36 and also downwardly so that a' portion of` the curved. edgeV 28 of the fabric nearest the clamped middle portion is caused to be located within the plane of bend of the bow member and disposed within theuiicompressed portion of the channel thereof. VThe left lhand arm is then swung a little in a countercloclc,

wise direction, thus to cause the roller thereof to act on and tobend the'left hand side of the bow member about a portion lof the cam face of thecam meinberand also to flatten the side walls' of the channel of the bow member into permanent engagement with.` the inserted portions of the loose curved bending or shaping of the fabric to bring the curved edge into the channel and `the shaping of the channel and the clamping of a portion of the fabric edge. is carried out in successive steps until one entire side of the fabric is clamped vpermaifiently into vthe, channel and the bow member is completely bent to the proper shape. lhe same series of operations Ais repeated on .the opposite. side of the fabric and channel. Thel handles 5S are operated at suitable times to. as-` sist vin the bending of the channel into bow form. y v

A half completed hood. with one completed bow member' is `then removed. from the device and the same roperation is cariiedi'out on :the otherfedge of theV fabric so thatafter the bow membeis'are applied, thehood with its bow members is completely shaped oris as .shown in Fig. 10.A The bow members retain thefabriein the shape imparted to it, without other restraining rmeans, and the shaped fabricis caused to incline the 'ends of the bow members toward each other, so that they are caused automatically to assume their` intended relative.

positions, as shownain Fig. l, without necessity rorforcing them into suoli position.

The straight side edges 30 of the fabric remain straight and lie-between the bows as shown. Side members 2O of channel shape are inserted over the loose ends of the filler sti'andsQG at the.y edges 30, as shown in Fig. 11, and the side walls .of said rmembers are compressed onto the filler strands whereby to bind them securely in .placeu The endsv of the side members 2O are preferably spotwelded electrically. to the bow members 1d and 16, thus rigidly to connect them.

The above method of shaping the fabric andthe bow members and simultaneously securing the fabric in the bow members can be effected by operatives inexperienced inv reedy manufacture.` LAs above stated, the

ciirve given the `curved edges 28 .of the fabric Vis important and is. determined mainly vby trial. yThe curve is such that when the fabricV is completely A,secured in the bow members, theedge28 of the shaped fabric occupies a plane which is vthe plane of the shaped bow member. i

Figs. r12, 13 and 1d illustrate in some dc-` grever the manner in which both the high and lowportions 12 and 12b, respectively,.of

the fabric are causedto .lie in the saine plane. ln Fig. 12,the fabric is illustrated at the start of the shaping process, the U- shaped line 141-CL illustrating the inaloutline of the edge. In Fig. 13, the Afabric is partly shaped and sections ofthe edge of lthe "fabric, between the low or middle portion and the high or end portions, have been bent forwardly and downwardly into the final plane of bend, the high end poiiionsl being yet above the final plane.Y In Fig. 14.-, all portions of theedge are shown as occupying the final plane of bend. vThe fabric naturally assumes the shape Vherein illustrated `in' the process of manufacture without the necessity` for shifting .the weave of, or shucking, the fabric, during the shaping thereof. Y Y the stakes 2st .of the fabric are clamped in the bow members, and the stakes are ineXf tensible, the fabric is held against shiicking during the shaping thereof and alsov in the i completed article.
