the'bars contact with the bottom. of the slots,
;.-In certainH-types of looms it is customary-to provide the drop wire bars} with which'said looms are equipped, withone or more bracketsas-may be required to prevent said bars from spreading andsagging. To this endv the brackets are pro but there is'al narrow space provided between the sides of thebars and the sides of the slots. When thexloom is in operation. the drop wire bars vibrate continually with the result that both the bars and brackets are subjected to excessivewear and it is necessary that they be replaced frequently. 1 7 1 The object therefore of this invention is to embody in the structure of the brackets that are provided for holding the drop wire bars, a clamping mechanism which will effectively eliminate the vibration of the bars and therebyreduce the noise and wear usually occasioned by the continual vibrating contact of the bars with the brackets. The invention consists in an improved clamping mechanism for the drop wire bars of a loom as set forth in the following specification and particularly pointed out in the claims thereof.
Referring to. the drawing:-- Fig. 1 is a plan view of the clamp mechanism of this invention, together with portions. ofthe In the drawing, 5 and 6 represent the front and. rear drop wire box plates respectively of a loom, 1 the drop wire bars and 8 a separator rod which constitutes a support for the warp threads. These members are all old and well known in the art and extend from one side of the loom to the other.
Mounted upon the box plates 5 and 6 is a bracket 9 which constitutes a brace and support for the dropwire bars I. The bracket 9 may be secured to either one or both of thebox plates as maybe desired and any suitable number of said brackets maybe provided as may be required. to support the drop wire bars, said numher being determined by the width :of the loom. In the present instance thebrack'et 9 is adjustably secured to the boxplatei by an angle-member i9 and bolt H. 1
The drop wire barsl ar'e locatedin slots l2 provided inthe bracket 9, said slots extending downwardly from the top' edgeof the bracket and the lower edge of thebar being seated at thexbottomof the slot, but preferably. there-is a very narrow space provided between the :sides of the bar and the sides of the slots'.:In the present instancethere are two drop wire .bars, il-- lustrated, but a third-slot lzisprovidedinthe I bracket 9 to receivea thirddropwire:barwhich is provided in certain looms, and still. otherslots andsbars may be provided. if it is so desir edwi-th outdeparting from the spirit of this invention.
Drop wires I3 well known in the art and for which the bars I are providedare illustrated in Fig. 2. These drop wires are provided withslots M to receive the'bars I and holes IE to receive the warp threads l6 of the loom.
A'vseparator rod 8 is located at the bottom of a slot H also provided in the bracket 9 and pro j'ecting downwardly from the top edge-thereof.
Pivotally attached at [8 to the bracket e is a bowed tension member l9 constructed of resillengthwise of the bracket 9, a' short distance above the top edge thereof and just above the upper edges of the drop wire bars I. Secured to the under side of the tension member l9 and in effect forming a part'thereof is a' cushion. 20
formed of a suitable compressable material such, for example, as rubber or leather. When the thereof is adapted to engage the top edges of the bars 1. The tension member l9is held de pressed and flexed under tension by means of a latch 2| which is mounted at the free end portion of the tension member 19. The latch 2I pro- .35" tension member I9 is depressed the cushion 20 jects through a hole 22 provided in the tension member, said hole being somewhat larger in diameter than the diameter of the rod from which the latch is formed, thereby permitting said latch to swing freely upon the tension member. The lower portion of the latch 2| is bent at- 23 to form a. hook portion which is adapted to interlock with a notch 24 provided upon the lower'j edge of the bracket 9. 'A nut 25 has screwethreaded engagement with the upper end'portion of the latch 2| and is utilized as a means for placing. a tension upon the tension member I9 and forcing the cushion 20 carried thereby 'intoengagement with ber l9 by manipulating the adjusting nut 25,-
ner to 'compress the cushion 20 duringsaid engagement.
A clamping device of this invention may be se- 7 cured at intervals to the box plates 5 and 6 to provide an effective means for clamping the drop Wire bars 1 between the cushion 20 and the brackets}! thereby preventing these bars from vibratingfl'with the consequent wear to both the bars 1 and brackets 9. It is evident'that anydesired tension may be applied to the tension memand the compression ofthe cushion 20 will vary according to the pressure placed upon the tension member by the nut 25. 1 f
It will be noted that in 'this device the-tension] member I9 maybe lifted to relieve the pressure upon the bars 1 as may be required when repairs or replacements are necessary and the tension member can be swung backwardly into a position which will not interfere with thefbars"! ordrop wires I '3. Duringthisimovernent ofthetension tachedtothetension member.
