te races rATaNr ot'rica JOHN WALKER, JR, or ELROSE PARK, PENNSYLVANIA, ssIeNoR .ro WALKER MANU- :IEACTURING corirANY, Inc, A CORPORATION OF PENNSYLVANIA r HEDDLE FRAME "Application filed January 8, 1929. Serial No. 331,031.

The object of the invention is todprovide 4 a perspective view of the lower portion improvements in 'teXtile machinery, and more particularly. in heddle frames for looms. h

5' Another. and 'more specific object is to provide in heddle frames means for stiffening the oppositely positioned rails, and for,

supporting the heddle bars with respect to said rails and to one another at one or more points intermediate of their ends, where ing and fixing the relation of intermediate portions of oppositely positioned heddle bars to the rails of the heddle frames, and for connecting such portions of said bars to each other, and thus indirectly connecting said rails together to stiffen the frame, in addition to stay rods which may be present and in use for such latter purpose.

Still another and more specific ob ect is members secured to the opposite rails of a heddle frame and disengageably connectedi to the respectively adjacent heddle bars, to-

' gether with a rod having bifurcated hookshaped end portions adapted, upon drawing the central portions of the oppositely dis posed rails and bars towards each other, to

straddle said members and engage said bars in hooked relation, after which the resiliency of said rails and bars returns them to V vicehas been constructed to lnsure this their original parallel positions.

lVith these of construction and" operation which are com an i11 drawin s in which Fi .1 is a front elevation of a heddle frame comprising top and bottom rails and heddle bars connected by tie rods operating in accordance with and embodying features compris 0 tary portion of Fig. 1 in elevation; and Fig.

to provide a pair of hooks or hook-shaped and other objects in mind, the present invention comprises further details.

fully brought out in the following description when read in conjunction with the acas. the case may be. consists primar ly n a central shank pork sitely positioned top and bottom rails 1 and 2, connected at their ends by any suitable -means such asstraps 3. Heddle supporting bars 4 and 5 extend longitudinally of the frame parallel with and spaced slightly from the neighboring frame rails 1 and 2,

and operatively supporting a bank or series of heddles. 6, which, are attached thereto in any well known manner.

l/Vhile not necessary to the operation of the present invention, a stay rod 7 is shown -f asextending between and in the plane of the rails l and 2.- -This rod is detachably secured to said rails,-and removably receives adjacent portions of thebars 4 and 5 in any suitable manner, as for instance by means ofa construction illustrated in de tall 1n a ,co-pendlng appl cation whlch resulted in Letters Patent N0."1,701,520. But,

as before stated, the position, shape and even :the'presence of this stay rod is inde-T' pendent of the tie rod or rods comprising the present invention. A

The rails 1 and 2 are satisfactorily maintained in adefinitespaced relation by the stay rod-referred to, but the presence of such rod does not-insure the desirable fixed relation that should exist between the heddle bars l and 5; as well between said bars and said-rails. Therefore, the present deprevious deficiency, andyet to be applicable to and detachable from a heddle frame without interfering materially with. the positions and operation of the heddles, and

permitting the shifting of such heddles'f whenever desired. To each of sand rails there is secured in any suitable manner the threaded portion 8 of a hook which also comprises a shank 9 angularly disposed with respect to said 'threaded portion, and a hook-shaped free end portion 10 adapted to normally receive one of the adjacent heddle bars 4 and 5, The tie rod proper tion 11, having bifurcated heads 12, providing spaced parallel fingers, each of which is recessed transversely inwardly from one lateral edge portion at 13 and terminates in a hook-shaped free end portion 14, also adapted to engage the adjacent heddle bar 4 or It is obvious that the shank 11 of the tie rod may comprise a single thickness of any suitable cross section, However, in order to produce commercially a highly efiicient shape of tie rod, it has been found excellent practice to form the same from two parallel strips of relatively thin metal rods, secured together in unitary relation throughout their central shank by any suitable form of rivets 15, welding, or the like, and separated at their bifurcated portion (as shown in Figs. 1 and to form in etlect a pair of spaced parallel hooks which are adapted to be positioned upon the opposite sides of the adjacent fixed hook member 10 by straddling the same.

In order to apply this improved tie rod in a heddle frame, the stay rod 7 if present must be at least loosened and removed at one end from the adjacent rail, after which the rails l and 2, together with their neighboring heddlebars t and 5, may be sprung towards each other until one of the double hooked ends of the rod 11 is passed over the upper bar t, for instance, and upon the opposite sides of the upper fixed hook 10, after 1 which the lower double hooked portion of said tie rod is passed over the lower heddle bar 5, whereupon releasing said rails and adjacent bars, their resiliency returns them into their original parallel relation and thereby draws the bar 5 into the lower hooked end portion of said tie rod, after which the stay rod 7 can be replaced. In order to withdraw said tie rod from the heddle frame for the purpose of longitudinally adjusting or replacing the heddles, or for other purposes, the foregoing procedure is reversed, and the rails and bars are drawn towards each other so as to disengage first one and then the other of the hooked end portion-sot the tie rod from said bars, in each case the stay rod 7, if present, having to be first disconnected and then replaced in operative position after the desired adjustment has been effected.

Having thus described my invention, what'I claim and desire to protect by Letters Patent of the United States is 1. The combination of a heddle frame,

comprising spaced parallel rails and heddle i bars, with members normally fixed to said rails and engaging said bars, and a laminated member comprising a pair of rods secured together at their central portions and a spaced apart at their end portions, whereby the adjacent ends of said rods are adapted to straddle the respective first members and the adjacent end portions themselves spaced apart and adapted to straddle one of said first members and be detachably secured to the adjacent bar, the opposite end of one of said rods being normally secured to the other of said bars, said rods thereby maintaining a predetermined distance between said rails and said bars. I

In testimony whereof I have aflixed my signature.

JOHN WALKER, J 1:.
