1 '0 oZ'Z whom it may concern:

\ it shown that l Riemann GRnnNLnA'r 'llnnrtan, a citizen of the Unitedfitates, and

a ir'esidei'it oil? the eity of Malden, in the county ct hfiiddlesex and Commonwealth of lrlzissacln setts, have invented certain new and useful Improvements in Rooms, of which the tl oilowing is a full. clear, and exact specification.

This invention relates to a type of lOOD'l disclosed 'n my companion application filed June it... 191W, Sela No. 175M233, a id which erentnated in Patent l lo 1236.545, April 1 ,ltlill. wherein a bobbiii-carry]no .slnrttle'. is dispensed with and thewe'lt thread is fed to a point within the shed and throijigrh an eye formed in the recip- ".th" e. and thereliiy woven into fthoijit break tor many hours at a t' a thus enabling burlap and other woven fabrics to heproduced at low cost. whether heavy or light.

Fig. at is a View from beneath of the beater bar showing the reed engaging device Fig. 5 is an elevation of the same. 6 is detail view 01" the reed controlling means. Fig. 7 is a sectional detail View of the lock employed in the mechanism. Fig. is a side elevation oi the weft-thread tension device. i ig. 9 is an under view of a. part thereof.

As shown in Fig. 1, the beater bar 1. is connected by arms 2 to a pivotal support 8 in a well known manner. and the weft thread 3 is fed through a hole a in the bar 1, being preferably conducted thereto by a flexible tube Behind the beater bar are two reeds (3. each preferably extending for one-hall the width of the shed. but whatever their exact length their inner ends must come in close alineinent with the hole l. These reeds are independently connected byerins 7 to the pivotal su 127th of: the beater frame, and are adapte to be intermittently engaged by andswin g. with the beater bar 1, in the tollowin manner, i i

As shown in Figs. l and 5, the under surt'ace oi the beater bar has pivotally attached thereto "four hooks two for each reed (if. one pan; facing in one direction and theother pairopposite thereto, a tension spring 10 yieldingly drawing Iard the other pair. for the engagement thereof with pins 11 (Fig. 1) projecting from the reecs. The two hooks each pair b'v aretied together to swing simultaneously a rod 12, and along side of these rods a bar 13 having lugs 1 engagingpins 15 on the rods, whereby a sliding movement of the bar in one direction,as to theright asillustrated in Fig. 4, will swingthe hoolrs at the right away from the posibility ot' engaging the associated pins 11, While the spring it). draws the otherpair o't hooks into the field.

of their associated pins. a detent l8 locking the bar. 1

shlitin the bar 13, two levers l6 For thus are pivotally at tached to the 'l ater bar 1, and connected at their lowehends by rods 17 to the peers if), the bar 1 having a downwardly and laterallyprojecting h1g5 20 deeach pair to.-

signed to be met by first one and then the other of the levers 16 as thejoicliers 19 a actmited andthcreby slide the bar 13 cor ingly. Hence each time a picker is actuated, the hooks t) at its side of the loom are put into condition for engaging the pins ll of the reed (5 at such side, andwhen next the beater bar 1 swings back, this reed will be engaged and brought back with it and made to perform the required beater action for that half of the fabric.

In order to yieldingly retain the reeds 6 in their non-beatingpositions, I attach to arm 7 of each reed a tension spring 21 whose opposite end is attached to a pair of bars 22, 23 between which is slidably carried a barie one end of which is attached to the arm 7. The bar 23 is elongated and coupled with a bar 25 at its other end. between which bars 25 passing through a slot in the bar 26 similarly controls the latter. This arrangement glv'QS an adjustable resilient support to the reel-.4,

properly holding them for their engagement by the hooks 9, and as a proper guide for the shuttle.

As shown in Figs. 1 and 2, the shuttle 35 is formed with an elongated eye 36 in a vertical plane, for I find that by having this eye vertical and elongated for nearly the entire length of the shuttle much more perfect work is performed. This shuttle is shot back and, forth through the shed on the beater'bar l by the pickers '19 in a well known manner.

The operation of-the loom is as follows: The warp 75 being threaded through the heddles in thensual' manner, except that there are four harness frames 76, two frames for each half of the shed. Fromthe heddles the warp passes between thedents composing the reeds 6 to the fabric being woven, and then as the harness. frames rise and fall, the shuttle 35 ispropelled through the shed from side to side, carrying the weft loop 3 through it. After each cast of the shuttle, one of the reeds 6 is engaged by the hooks 9 and swung forwardwith the batten 1, properly beating in the last-laid weft thread section; and just before the shuttle 35 leaves a shuttle-box 33, a hook 43 engages the upbetween its ends, a plurality of harness frames, ashuttle having an eye through which the weft thread passes, and means for 3; Aloom comprising a beater frame hav-' ing a heater bar provided with a vertical hole near its mid-length, means including a flexible tube for delivering the weft thread through said hole, a plurality of harness frames, a shuttle having an eye through which the weft thread passes, and means for propelling the shuttle along the beater bar.

' 4; A loom comprising a beater frame having a heater bar, a shuttle having an eye propelled along the beater bar, a plurality of harness frames, means for delivering a weft thread to a point within the shed and thence through said eye to the fabric being woven, a loosely supported bobbin located at each selvage edge of the fabric be ing woven, a thread from within the bobbin passing to the selvage, and automatically operated means for putting the portion of the weft thread between the fabric and shuttle around said bobbin. 7

5. A loom compris ng a heater frame having a heater bar, a shuttle, means for propelling the shuttle along the beater bar, the

shuttle having an eye through which is passed the weft thread from a point within the shed to the fabric, and a plurality of harness frames, said eye being extended for nearly the full length of the shuttle. I

In testimony thatl claim the foregoing invention, I have hereunto set my hand this 22nd day of May, 1919. I

RICHARD GREENLEAF TURNER.
