Tn the present instance, the uprising reed "support 5"21t e'gich end of the layhas 'cla'mpeol theretoe bearing Gfthe end poi tionW 'of'whieh' 'fu l zind held' toth i holflfl Th en 'SHPPQPP i e-me eva s s th end members 11,. the upper end portions of which are provided with the slotted arms 12 whereby the upper rail 13 of the swinging reed may besecured adjustably to the reed frameby mea nsof the bolts 14 preferably provided with wing nuts 15. Eaelrof the end members 11 has extending from its upper end a lug 16, which in the present instance is shown as provided with a pin 17 which furnishes a pivotal member for the 1 reed as; a. whole; It is understood, of course,

lower member 18 of the reediframe are the p'rojections21-to each of which is secureda bearing 22, as indicated in Fig. 2. The means .forsecurmg the parts ]L1St described together. may be of any usual character, such as the bolts23, and, as shown. thebearmgs 22 are open, that is, the space 24 between the front-and rear legl portions of the bearing is open for the ready reception of means to be presently described for positively actuating thereed to swing to either its full beat up position or to its partial beat-up position,

and lock it in either position. v

In accordance with the present invention, the lay is provided with a shaft extending lengthwiseof the lay, and offset or eccentric portions secured to the shaft engage the bearings extending from the reed frame. the construction being such that upon rocking movement of the shaft, the reed will be given its positive swinging movements and locking function, as hereinbefore stated.

The shaft above described preferably comprises therock shaft 25. the end portions of which are supported in brackets at each end of the lay. As indicated in Fig; l. the bracket 26 for supporting one end ofthe shaft 25 has the horizontally extending arm and the upwardly extending web 27. which may be secured to the reed support 5 by means such as the bolt 28 and the previously described bolt 10. So far as this feature of the invention is concerned, of course, the

brackets may be variously contrived, their function being to provide means connected to the lay for properly supporting the shaft 25 for rocking movement.

' The shaft 25 has secured thereto at spaced points along the same the eccentrics or off set. portions 29, of which theremay be any suitable number in accordance I withthe length ofthe reed, and each; of the offset or eccentric portions 29 is received within one of the open bearings 22 projecting from the lowerrail of the reed, the construction being such that should the shaft be rocked in one direction it will positi vely swing the reed to its full beatjupfj positionj uponfiits pivotal support 17, and upon rocking movement in an opposite direction will swing the reed positively to its partial beat up position. The construction of the means for shifting thereed upon the lay is such that the reed is held by positive, non-yielding means in either its-partialbeat-up or full beat-up position. I Thehorizontalportion of the bracket- 26 is preferably extended rearwardly, asat. 30, and pivotally supportedthereon, as at 31:, is a toothed segment 32,1the teeth 33of which are in engagementwiththe teeth. of. a gear 3 1 secured to the shaft25, the effect being that upon rocking-movement of the toothed segment 32, theshaft 25 :will be ;positiv ely rocked. 'f. Appropriate rocking movements are; imparted to the toothedsegment 32 at times through the-terrymotion which is common in terry looms, and comprises, usually acam or pattern actnated-throughga lever, to cause the production of the partial andfullbeat ups alternately. .Thelsegment .32'isi provided with an opening .35, in. which is. pivotally supported at 36v the upperend portion of the rod 37 :the. lower; end 'portion, of -;which ,is

connected to'the regular-terry arm, itbein i side of the,loom. The layl isv cut away. at 38, shown, in

'Figs. 2 and 3, andarace'plate39" has its rear edge 40 so positioned withirespect ,to the reed that whenthe latter is in its full beat up position, as indicated by full lines Figs. 2 and 3, thedents-of the reed will bear against the rear edge of the race plate, or approximately so. i W

From the construction described as one good practical form of the present invention, it will'be apparent-that the swinging reed is under positive control of vmeansto move it to andlock it in its partial beat up position, as shown by dotted lines in Fig. 3, for a desired number of picks, and ,then to move it positively to its full beat upposition, as indicated by full lines in Fig. 3, to there by produce the terry loops. The lay itself indeed, it may be, moved to and locked in its full beat up position for a desired number of picks should aplain portion of fabric be desired at diiferentpoints lengthwise of the fabric. In any. event,the reed is .-under positive control at all times, both during its movements to and from its full beat up position, and is locked in both its full beat up position and in its partial beat up position, a condition which is especially advantageous where wide terry fabrics are being woven, and as contributing to the production of such wide terry fabrics, the organization and construction hereinbefore described provides that the swinging reed may be positively connected to its actuating means to produce the terry loops at any desired number of points in the length of the reed. What is claimed is;

1. In a loom for weaving terry fabrics, the combination of the lay mounted for movement towards and from the front of the loom, a reed pivotally connected to the lay, a. shaft mounted upon the lay and having eccentric portions connected to the reed for successively and positively moving the reed to partial beat-up position and full beat-up position and locking the reed in each of the two positions, and means for actuating said shaft periodically.

2. In a loom for weaving terry fabrics, the combination of the lay mounted for movement towards and from the front of the loom, a swinging reed and a rock shaft mounted on the lay, eccentric connections between the rock shaft and swinging reed at different points in the length thereof, and means for rocking the rock shaft in relation to the lay to successively move the reed to partial beat-up position and full beat-up position and lock the reed in each of said positions.

3. In a loom for weaving terry fabrics, the combination of the lay, a swinging reed mounted thereon, a rock shaft mounted on the lay, positive connections between the swinging reed and rock shaft, and means for positively holding the reed in either of two positions while the lay moves back and forth, and operable to rock the rock shaft at intervals relative to the lay movement that the reed may be positively moved to and locked in its partial beat up position and then positively moved to and locked in its full beat up position to form terry loops.

4. In a loom for weaving terry fabrics, the combination of the lay having a swinging reed, reed positioning means carried by the lay, positive connection between the reed and positioning means and-operable to hold the reed in either of two positions while the lay moves back and forth, and an actuator for operating said positioning means at intervals relative to the lay movement to positively move the reed to and lock it in its partial beat up position and then positively move it. to and lock it in its full beat up position to form terry loops.

5. In a loom for weaving terry fabrics, the combination of the lay having a swinging reed, a shaft on the lay having eccentric connections with the reed at each end thereof and at a point between its ends, and means for rocking the shaft at intervals relative to the lay movement to move the reed positively to and from its full beat up position and positively lock the reed in each of said positions.

6. In a loom for weaving wide terry fabrics, the combination of the lay having a swinging reed, a shaft on the lay having eccentrics located at different points along its length and connected to the swinging reed, and means for rocking the shaft to positively move the reed to and from full beat up position.

7. In a loom for weaving terry fabrics, the combination of the lay having a swinging reed provided with lugs extending from its lower portion at different points across the loom, a shaft having eccentric portions positioned along its length to engage with said lugs for positively moving the swinging' reed and looking it in full and partial beat up position relative to the lay, and means for rocking said shaft at intervals during weaving to cause the reed to form terry loops.

8. In a loom for weaving terry fabrics, the combination of the lay provided with a swinging reed, adjustable pivotal supports for the reed, a shaft mounted on the lay and having off-set portions connected to the reed for swinging it positively to its partial and full beat up positions relative to the lay and looking it in each of said positions, a terry rod actuated at intervals relative to the lay movement, and connections between the terry rod and said shaft to rock the shaft in one direction to swing the reed positively to its partial beat up position and lock it there for a number of picks and then rock the shaft in the opposite direction to swing the reed to full beat up position and lock it there to form terry loops.

9. In a loom for weaving terry fabrics, the combination of the lay having a regular beat up movement, a swinging reed carried by the lay and having open bearings disposed at different points across the loom and extending from the lower portion of the reed, a shaft mounted on the lay and having eccentric portions at different points along its length which are engaged by the open bearing of the swinging reed, and means for actuating the shaft at intervals relative to the lay movement to move the reed positively to partial beat up position for a number of picks and then to full beat up position to produce terry loops.

In testimony whereof, I have signed my name to this specification.

CARL D. BROWN.
