LOOSE-REED-ADJUSTING MECHANISM-Eon Looms Application filed; March 4, 1927. Serial N0.j1.:2,'715..

v In the use of looms weavingjcloth known to i the textile trade as'split basket, or similar weaves, it has heretofore been found nosessary to us'etwo-rigid; reeds in the lay of the loom, one back of; the other. .It has also been found in practice that even by the use of two reeds for this kind of= weave the result has been very unsatisfactory, as the warp threads ,willroll. together and" knots or unevenness in the warp threads will catch onthe reed wires and break the warp threads. ,v The object of my invention is to improve the construction ofa loom weaving split bas ket or'similar weaves; whereby the usual reed restor fasteningplate is removed and the lay of the mom is thereby provided with a reed loosely'held'inthe lay of the loom.

Another object of my invention is to provide the-lay of a loom with means for ,adjusting'and' limitingthe movement of the now loose r'eed' in the lay of the loom.

Anotherobject of my invention is to provide the lay of aloom with means for adjusting thereedilengthwise in thelay'ofthe v ,A further objectof invention is to simplify thelconstructifon of the means for ad justingto limitthe swing of the layv and meansrfor adjusting the reed" lengthwise in the lay,'the reby reducing the 'cost of constructing saidreedi controlling and adjusting means to a minimum,

' invention conslsts in the peculiar and the lay ofa l'oom,js aid elements having means loom, means for adjusting and limiting the swinging movement of the loose reed in the lay and means for adjustingthe reed lengthwise in the lay, said elements having details of construction, as will be more fully-set novel construction of elements connected to Figure lyisa transverse vertical sectional 4 view. of theupper part, ofa loom, showingtlie lay provided with my improved loosereed forward position. 7 I j I I v Figure 2 is an enlarged 'detailsectional view of the lay'ln itsback position andshowing adjusting mechanism and with, the lay. in the the lay provided with my improvedloose-reed adjusting mechanism, ins ection.

Incarrying my invention. into practice I eliminate the usual reed rest or reed fasten ing. plate,;not shown, from the recessed back portions of the lay and substitutein place thereof, my improved loose reedadjusting cessed portion 6 of the lay' d by screwsl l- 4,"

and 5 a vertical member having 'a slot G ad- L shaped bar having a horim in which the top of the reed g is loosely I. mechanism l', which has the following conv c p 7 in the L shaped bar 2, the inner ends of the screws 11,11, engaging with-the reed bar, 9.

Each screw ll' has a'nut shaped head 12and a lock nut 13. A reed lengthwise adjusting member 1A is placed at each end of the L shaped bar 2. Each reed adjusting member '14 has'an arm 15 engaglngwith each outer end of the reed f and an arm'16 on which is fixed a screw 17 which extendsthrough the slot Ginthe L shaped bar 2 and the screw 17 has a fastening'nut engaging with the bar :2. r r

By this construct on, as shown n Figures 5, 6, 7 and 8, the reed ad ust-mg bar. 9 1s adjustably attached to the fixed bar 2, by the guide pins 10, 10. Thereed adjusting bar 9 is itCljIlSlIGClllO control the rearwardswinging movement of the reed g in the lay d, by the screws 11, '11, the shoulder f on the lay 03 forms astop to limit the forward swinging movementof the reed g, in the lay at, and the reed g is adjusted lengthwise by the reed lengthwise adjusting members 14, 14, which may be reversed for adjusting v longer'reedsf After adjustment the nuts 13,

13, and 18,18, aretightened, thereby securing the parts in their adjusted'positions,

, Inremoving the reed rest or fastening plate, not shown, from under the reed, as

heretofore used, a vertical'space is gained .on the lay of about five eighths of an inch,

thus allowing; the reed to drop down in this space or in other words, allowing anlin'c'rease in the length of the reed wlresordents. This dropping down of the reed brings the center portion of the reed wires where they are more flexible and this also brlngs the center portion of thelreed wires on a line withthe warp threads,'as indicated in dotted lines in Figure 1. By thus positioning the reed wires,

in U! [knotsor irregularitiesinthe warp threads will spring the center portion of the reed wires apart and allow the knots or irregularities to pass through the reed, without breaking the warp threads.

' In theoperation of my improved loose reed adjusting mechanism for looms, a rearward movement of the lay Z, will cause the loose reed g to swing forward until the bottom of the reed contacts with the stop shoulder as shown in'Figure 2. A forward movement of the lay will cause the reed to'move backward as shown in Fig.1. This loose holding and controlling of the reed in the lay now allows the reed to ease away from knots and other irregularities in the warp threads, thereby allowing the knots and irregularities on the warp threads to easily;p ass' by the reed wires and through the dents in the reed,

without breaking the warp threads. In fixing up a loom for weavlng' split basket or similar weaves, as heretofore done,

the two reeds are set inthe lay one back of the other and offset, so that the. reed wires of the back reed are on a center line with the dents in the front reed, the two reeds having the same number of reed wires as used in my single reed for the same purpose, This 011 setting of the two reeds is necessary and "in hooking the warp threads through these on set dents, it requires approximately six times the time required to hook the warp threads through the dents of a single reed and as it is impossible. for the loom fixerto clearly see what he is doing, he is liable to hook the I wrongwarp threads throughthe dents, thereby causing a miss weave in the cloth.
