' This invention relatesto looms andis more particularly directed to the reedmounting whereby all lost motionbetween the reed and its supporting elements is avoided] It is now the ordinary the reed for movement with the lay by mounting the upper and lower portions of thereed in the handrail and'lay beamrespectively in order that up, the weft or filling thread may be driven vaccurately to the fell of the cloth. Lostmotion may at times occur between the reed and its supporting elements and particularly is this noticeable in loose reed motions, where the reed attimes mayswing about one ofits supports should'the shuttle'become trapped in the shed to therebyprevent breaking of the warp threads.

One of the objects of the present invene tion is to provide means for taking up any lost motion that may occur between the reed and its supportingelements and especially in loose reed motionsn In' accordance with the present invention the hand rail is provided with a longitudinal groove for receiving-the upper" reed bar or other dentholding means, and devices are provided whereby any lost motion thatlmay occur betweenthe reed-'andits supporting elements may "be readilv taken up,-' so that thereed itself shall effect the beating-up movement of the weft or filling threads accurately to the fell of the cloth. Inthese loose reed motions wherein the locking bar rests uponthe lower reedbar it is' especially desirable that all {lost motion .be prevented, as

otherwise" the reed itself may be injured and the beat-up improperlyfmade."

- The; invention and novel features jwillbest I be made clear from the following descrip} tion and accompanying'drawings of one good "form thereof.

In the present instance of the invention the bearing lugs 20 are constituted by plates secured as shown to the rear face of the hand rail14: and the lower portion of the plates or thickened. 7 V Above the secured bolts 19 are the rail turning devices which in=the present instance of theinvention consist of adjustingiscrews 21, which extends through the upper po'rtion ofthe hand rail, and at the front thereof such adjusting screws are provided with'a notched counter sunk head 22 that maybe readily turned by. means of a hand implementwhen adjustment of the hand ira'labout the longitudinal axis formed by the fulcrumlugs becomes desirable. The adjusting screws 21,
