HfTOP/VEY' Patented Nov. 20, 1951 UNITED STATES PATENT OFFICE COMBINED HEDDLE AND LINGO AND METHOD OF MAKING THE SAME This'invention relates to combined heddles and lingoes and to the method of making the same. More particularly the invention relates to the connection between a lingo and a heddle, and to the method of making such connection, whereby there is produced a composite article particularly adapted for use in Jacquard looms and the like.

The heddles now being used in the United States in Jacquard looms and the like are very largely those made of thin flat metal or wire of integral structure. Consequently the lingoes now available are those designed to make connection with such thin flat metal heddles. Such lingoes are of the type having a flattened portion at the top, such flattened portion incorporating an eye having a slot through one side thereof. The eye at thetop of the lingo is connected to the eye at the bottom of the heddle, such latter eye being punched in the thin fiat stock of the heddle, by turning the lingo suificiently relative to the heddie to allow the thin flat portion at the bottom of the eye of the heddle to enter the eye in the lingo through the open slot therein. After such assembly the lingo is turned so as to lie as a prolongation of the heddle, the design of the eye'on the heddle being such that the lingo cannot be withdrawn therefrom unless it is turned to an appreciable angle with respect to the heddle.

Although such described connection between heddle and lingo is satisfactory when the heddle is of the thin flat wire type, it is not when such lingoes are used in connection with a heddle, usually imported from abroad, which is made up of two round wires combined side by side and incorporating between them a separate thread guiding eye. The lingo attaching eye on such latter type of heddle has its loop formed from the two round wires. Consequently such loop is of such thinness that it readily slips out of the eye in the lingo through the open slot at the side. Thus considerable diinculty has been experienced in the use of the conventional type of lingo with the latter described heddle, the lingoes being dislodged from the heddle very easily both during nstallation of the combination of heddle and lingo, and also during operation of the loom.

It is accordingly an object of my invention to provide an improved connection between a heddle and a lingo whereby the two cannot become accidentally disengaged.

It is a further object of my invention, in a preferred embodiment thereof, to provide such novel connection between the heddle and the lingo whereby the-conventionallingo maybe satisfac- 2 torily employed with the latter described heddle discussed above, that is, that formed from two combined round wires.

Another object of the invention residesin the provision of a novel method for efiecting a permanent connection between the lingo and heddle, such connection, however, being permanent only so long as desired, the connection being readily broken by means of easily manipulated tools.

These and further objects of the invention will be more readily apparent in the following description of a preferred embodiment thereof.

In the drawings accompanying the disclosure and forming a part thereof:

Fig. 1 is a View in front elevation of a combined heddle and lingo made in accordance with the invention;

Fi 2 is a view in side elevation of the'combined heddle and lingo shown in Fig. 1;

Fig. 3 is a view in front elevation, in enlarged scale, of the connection between the lingo and heddle shown in Fig. 1; and

Fig. 4 is an enlarged view in side elevation of such connection between the heddle and lingo.

Referring to the drawings, in the particular embodiment of my invention therein shown, 2 is a Jacquard heddle made, in this instance, of two round wires soldered together and combined as explained, such heddle having an eye 4 at the upper end for the attachment of the control cord of the Jacquard mechanism. A warp eye 6 is incorporated in the heddle intermediate its ends, as shown, and an eye 8 is provided at the lower end of the heddle for the attachment of the lingo I 0.

The lingo Ill which, as above explained, is designed for attachment to the ordinary thin flat metal heddle, is provided on its upper end with a flat portion 12. Within portion I24 there is provided a longitudinal slot or eye Hi, there being a transverse slot it through the forward wall of the eye, such slot extending inwardly into communication with slot M. The portions of the sidewall of the lingo eye abutting the said slot it are substantially rigid, so that slot l6 remains of substantially constant width. It is through such slot l6, which, in the embodiment shown, is located substantially midway between the top and bottom ends of eye l4 and at a right angle to the length of eye l4, that the eye 8 of the heddle is introduced into eye I4. It will be apparent from the drawings that the eye 8, which is formed from two combined parallel round wires, may quite readily slip out through the slot l6 during operation of the loom, particularly-if the lingo i is jarred upwardly and becomes turned slightly out of the vertical.

The present invention provides readily applied means whereby the eye 8 of the heddle is prevented from detachment from the eye 14 of the lingo after the lingo and heddle have been assembled as shown. More specifically, such means is in the form of a stud stably held within the eye of the lingo and 'blocking the inner end of the slot l6. Such means, in the preferred embodiment, takes the form of a hollow, easily deformed rivet l8 made, for instance, of copper, such rivet having a preformed head 20 and a cylindrical stem 24. Rivet I8 is preferably so chosen'as to size that before it is headed or clinched in the lingo eye its stem 24 fits snugly and is held stably inposition by engagement with the rear wall 26 of eye is and with the two confronting inner corners 28' and 3E! of the slot It. The rivet, unheaded on itsforward end, is inserted in a direction from left to right in Fig; 3 into the eye [4 after eye 8 has been insorted into eye I 4 of the lingo, and.wi-th the loopof eye 8 located in the upper end of eye it, following which the previously unheaded end at the right in Fig. 3 isupset or headed to form the fiange 22. The heads or flanges 28 and 22 of the rivet overlie inner portions of the side faces of part E2 of the lingo bordering the eye I land thus prevent axial motion of the rivet with respect to part [2.

It will be apparent that, with rivet it so positioned,. escape of eye 8 ofrthe heddle from eye MS of the lingois effectively prevented. At the same time, however, the upper portion of slot H5- in the eye of the heddle is left free and unencumbered, thereby allowing the heddle and lingo to move angularl-y relative to each other to a substantial degree about the connection between them. This allows the lingo to. maintain the heddle in the desiredvertica-l position, andproduces a combination which functions much more satisfactorily than does the combination of heddle and lingo in which a rigid connection is employed between such parts.

The connection. of the invention displays the further advantage that the heddle and lingo may readily be disassembled if, so desired. When it is desired to detach the lingo from the heddle, all that is necessary is'that the rivet 58 be removed. This may be. accomplished ina variety of ways including for instance, by the grinding ofi of one of the heads 2% or 22 of the rivet, allowing its axial withdrawal, and by the drilling of the rivet from the eye- Preferably, however, removal of the rivet is effected by the punching out of the rivet from the eye M by a hand pressing tool.

Although I have disclosed as preferable the use of a hollow rivet to block the entrance to the slot [6 in the eye of the lingo, it is to be understood that within the scope of the invention various other stud providing means functioning in a similar manner may be employed for such purpose. Included among such means are, for example, a solid rivet, a bolt, and a cotter pin. Furthermore, although it is preferred to employ a deformable stud member, the central portion of which is of such diameter that it is stably held between the rear inner wall it of thelingo eye and the inner corners 28 and 39 of the transverse slotbeforethe stud member is headed or deformed, it is possible to. employ a deformable stud member, the central portion of which is of. smaller diameter, so that, for example, it will slide along eye M. When such smaller diameter stud member is employed, the deformationthereof to form ahead thereon will be carried out-so as simultaneously to upset the central portion to increase itsdiameter so that it 4 snugly engages the wall 26 and the corners .28 and of the lingo eye, thereby to immobilize the stud member and to block slot l6.

Although for purposes of illustration I have described and illustrated preferred embodiments of the combined heddle and lingo of my invention and of the method of making the same in accordance with my invention, it is to be understood that my invention is not limited" thereto since it is capable of considerablexvariation as to details. The invention is therefore to be defined by the scope of the claims appended hereto.
