' spams 139-88) 1 This inventionpertains toan improved connecting means. forming a part of loom harness frames and by which said frames are attached to the harness cords or similar'means by which the frames are actuated.

It is a general object of the invention to devise a simple connecting means. of the type described which shall be adjustable withinlimits, easily attachable to or detached from its cord or the like, and which shall further have as a cooperating part thereof a locking means adapted to. serve the multiple function of maintaining the adjusted positionof the connectingmeans and also,.of. preventing unintended detachment of the cordsor the like.

Other objects and the manner in which the invention is to be put into practice will'be apparent from the following more detailed description.

Looms for weaving are provided with two or more harness frames carrying numerous heddles through which are threaded warpthreads. These;

frames are reciprocated in a manner known to those conversant with the art through connections in the form of cords, straps or the like whichare attached by various forms ofconnectingmeansto the top and bottom railsof the frames. A simple form of hook is frequently utilized,'the same being threaded into the wood or other frame material. It is desirable that these hooks or eye screws beso disposed as to. be threaded into or from the frame a few .turns for adjustment purposes and that they be. locked ina particular adjusted position. To that end, according to'the prior art, the hook shanks have been flattened for a shortdistance, and a detent having a fork at one end for engaging the flattenedshank screwed to the frame. The detent has no other effect than that of preventing turn ing'of the threaded connector and, in the event an adjustment is to be made, considerabletime and effort is involved in removing the holding screw for the detent, effecting the adjustment, and then returning the detent to position and inserting and tightening the screw. I

' According to the invention, a simple eye screw or hook with a threaded shank or the like, is locked in position by a small, spring strip fixed at one end adjacent the eye or hook and having at its other end some sort of slot which is positioned to embrace the hooked portion of the connection in a manner to prevent its turning and also, so as to prevent unintended detachment of the cord or other harness member by which the frame is actuated. To release a cord for detachment or to free a connector for adjustment, it is only necessary tov press the spring locking. member toward the .frame .rail. After release, it immediately springs back to its normal locking position.

Theinvention will be described in greater. detail by reference to the accompanying figures of drawing wherein practical forms of the invention havebeen shown- In the drawings:

Fig. 1 is an elevationalviewofa harness frame.

to which the invention has been applied.

. Fig. 2 is a perspective view showing one form which the invention may take. Figs.-3 and 4 are views similarto Fig. 2, but showing other forms of the invention. Now referring to Fig. l, a harness is normally comprised of top and bottom rails l0 and! I tied together attheir ends to struts I2 and I3 to form a rigid rectangular structure. The rails are frequently of wood and the struts of metal, but other materials are employed and for the purposes of this invention the materials arenot of importance. A plurality of heddles M are threaded onto and carried by heddle bars l5 and 16 supported at their ends in the struts I2 and I3, and intermediate their ends by hangers H at appropriately spaced intervals. Other heddle supporting means are commonly used and that herein shown is merely given by way of illustration. r

At-a point adjacent each end of both the top and bottomrails provision is made for connecting the frame unit to harness cords, straps or the like which run to top or other motions and to harness cam and treadle means all in a manher well known and a description of which need not-be given here. These cords are designated at l8 and terminate in a, loop or other connecting faciilty which shall be complementary to the connecting means of the frame and which is subject matter of the instant invention. Eachco'rd attaches to a hooked member I9 and is locked against unintended release by a spring member 20 which also prevents turning of the hooked member. 7

To illustrate in greater detail, and referring to Fig. 2, a hooked connector [9 comprising the hooked end 2| and threaded shank 22 is screwed into the wood or other material of the rail ID. The shank 22 is as long as required for holding and also provides for a small amount of adjustment in levellin th frame. Of course, there are other ways to adjust the position and limits of movement of the mechanism, and this adjustment serves as a final means of effecting a slight alteration in the relationship of the parts, and incidentally, a simple and very speedy one.

The hooked part of the connector is desirably to be maintained directed as shown in order to avoid interference. It is also desired that once set, the position of a hook will not become changed during normal operation. The spring lock 20 is attached by screw 23 to the rail 10 and is so formed that normally it maintains the position it occupies in Fig. 2. The free end of the locking member is slotted as at 24, this slot being a free fit over the hooked end 2|. The slot might be open ended, but that is not preferred. When a hook, ring or other complementary connector at the end of cord I8 is to be attached, the member 20 is pressed toward the rail I until the open end of the hook is exposed for the reception .7

of the ring or the like. When the parts are linked together the lock is released and it immediately snaps back to hook closing position.

Similarly, if an adjustment is to be made the lock is pressed toward the rail until the slot is freed from the hooked end. One or more turns of the hook in either direction may be made as required whereupon the lock may be released and will automatically spring back to its normal position.

A whole or a half turn. may be made, the length of slot 24 being sufficient to accommodate the hook when headed in either direction.

Now referring to Fig. 3, similar parts are indicated by like numerals with primes. The

spring locking member here is of different shapeand is considerably stiffer if of the same gauge material. It has two

slots

25 and 26 so it may not be sprung out beyond the hook loop. It'lS adapted to function with an open hooked member only and when adjustments are -made they are 21, and the terms slotted strip, locking means,v

etc., refer to the parts 20, 28 or fair equivalents thereof as covered by the appended claims.

It is to be understood that attaching meanssubject matter of the case may be used at all points of connection of the harness to the frame, or at some only of those points.

While eye screws or hooks such as these are well adapted to be threaded into wood, they may be of the type to thread into metal-rails or into metal or other inserts or the like held in the material of the rail in any convenient manner. Normally but not necessarily, adjustment of a hook involves disconnecting a cord therefrom.

While certain preferred embodiments of the invention have been disclosed, it is to beunderstood that the invention is not limited thereto. This patent is, therefore, not to be limited other than is necessary by the scope of the appended claims.

I claim:

1. For loom harness frames which have top and bottom rails to which are connected harness cords, an improved harness cord attaching means which comprises a hooked member threadedly connected to a rail of the frame and adapted to receive a complementary attaching portion of a harness cord, and means to prevent unintended detachment of the cord and for maintaining the and bottom rails to which are connected harness cords, an improved harness cord attaching means which comprises a hooked member having a threaded shank for engagement in a rail of the frame and adapted to receive a complementary attaching portion of a harness cord, and a means to prevent unintended detachment of the cord and for maintaining the hooked member in a predetermined, adjusted position, said means comprising a resilient strip attached at one end to the frame at a point adjacent the said hooked member, the opposite end of said strip defining a slot of length and width sufficient to embrace the hooked portion of the member and to prevent rotation thereof as long as the slotted strip is in engagement therewith, said opposite end being relatively free and normally'maintained by the resilience of the strip in position to engage the hooked portion of the hooked member.

3. Mechanism as defined in claim 2 wherein said hooked member is open for the reception of the complementary attaching means.

4. Mechanism as defined in claim 2 wherein said hooked member is formed as a substantially.

closed eye.

v5. Mechanism as defined in claim'z wherein said resilient'strip is provided with a slot divided intermediate its ends so one part thereof embraces the hook shank while the-other embraces the hook end.
