To allwhomit may concem; i I

Be it known that I, JACOB .KAUFMANN, a

citizen of the United States, residing at Ph iladelphia, in the county of Philadelphia and State of Pennsylvania, have invented oer.- tain new and useful Improvements in l-Ieddles, of which the following is a specification, 1

My invention relates to heddles for loom harness, and particularly to that type of heddle which is made from a thin, flat strip of metal or wire having a central eye for the control of the warp, and mortises at the ends thereof for mounting the heddles on the supporting bars or rods of the frame.

The objectof my present invention is to provide an improved form of heddle of such construction whereby one or more heddles may be mounted in the frame at desired 10- cations, either for the pur ose of replacinga broken or damaged hed 1e, or where it is desired to increase the number of heddles in v the frame, and without dismantling the supstood from the following description, taken porting bars or rods from the harness'frame. The nature and characteristic features of my invention will. be more readily underin connection with the accompanying drawings formi part hereof, in which Fi re 1 is an edge view of a heddle embody ng the main features of my present invention, the same being shown mounted on a the supporting bars or rods of the harness frame;

, Fi 2 is a face view of the heddle shown in Fig. 1, the supporting bars being shown insection;

Figs. 3 and 4 are enlarged face views of the upper and lower mortised end portions, respectively,- of the heddle of my present in-,

vention; and

.Figs. 5 and 6 are perspective views of the, upper and lower end portions; respectively, 4 o

the heddle, the same being shown in the act of being mounted'on their respective heddle supporting bars.

Referrin to the drawings, in the panics;

lar embodiment of my invention therein shown, 7 is the main or body-portionof the heddle, which is made from a thin, flat strip" of metal or wire, and in Which'the central warp controlling e 8 is formed bySIi/t and manner,

' the heddlewith respect thereto. The mortise 9 is located off-center with respect to the side edges of the flat strip from which the heddle is formed, whereby there will be provided, on one side of the mortise 9, a strip 10 of a width appreciably greater than that of the strip ll'left on the other side of the mortise. The narrower strip 11 on one side of the mortise is transversely cut or slit as at 1 2, which slits are preferably located near the lower ends of the mortises at the top and bottom respectively, to thereby provide, at each mortise, a short length 13 of the metal extending upwardly above the lower end of each mortise.

The strips 10 and 11 forming the shankson each side of the-mortise 9 are preferably also provided with oflset portions 14, formed by bending the metal in any preferred shape.

out of the main plane of the strip of which the heddle is formed, the purpose ofthe ofi'set portions 14 being to. prevent rotative -movement of the heddle proper with respect to the supporting bars 15.

- By the arrangement above described, there will be provided an improved-type of beddle which may be conveniently and expeditionslymounted on the-heddle supporting bars at desired locations, without necessitatingthe removal of the supporting barsfrom the harnessframe. I

mount one of said heddles on the support- When it is desired to ing bars, the heddle is brought with the upper mortise adjacent the upper supporting bar 15, and with the slit 12 of the shank 11 near the, upper edge-of said supporting bar,

whereupon the relatively narrow strip. or

shank 11 may be slightly sprung out of its normalposition. to straddle the supporting .bar 15 (see'Fig. 5), and the heddle, is then pulled downward until the slit 12 passes the lower edge of the supporting bar 15, whereupon the shank 11 may be permitted to reslime its normal position, and the upper end of the-,heddle will be then properly-mounted on its supporting bar 15. Similar procedui e may now be followed at the lower endlof the heddle, namely," theslit12 -is' narrow shank 11 of the mortise at the lower end of the heddle may be sprung out of its j normal position, to straddle the lower sup-.

porting bar 15, and the lower end of the heddle may then be pushed downward until the sli 12 thereof passes the lower edge of the ower supporting bar 15, whereupon the narrow strip 11 may then be permitted to resume its normal position and the lower end of the heddle will then also be properly mounted on its supporting bar 15.

It will be noted that by this arrangement the heddle may be readily mounted in the frame at any desired location without unduly straining the heddle or the supporting bars, and when so mounted, the location of the slits 12 is such that there is no possibility of fouling the warp ends'which pass adjacent a heddle of this construction, because,

' when the frame is in the uppermost position in the loom, the slit 12 at the lower end of the heddle will be located below the upper edge of the lower supporting bar. Furthermore, the portions 13 at the lower end of each of the mortises will serve to support the heddle with respect to the supporting bars when the strain is reversed, that 1s, when the frame is at its lowermost position in the 100111, in this manner preventingaccldental disengagement of the heddle therefrom. Furthermore, by locating the mortise 9 at each end of the heddle ofi-center with respect to the side edges of the strip, the

relatively wider shank 10 forming the'solid side of the mortise will afiord the requisite .degree of stifiness and thereby maintam'the mortised endsof the heddle against bending supportingbars, saidmortises being'formed and deformation.

Having thus described the nature and characteristic featuresnof my invention, what it claim as new and desire to secure by Letters Patent, is:

1. A heddle made from a thin, flat strip of metal having mortises near the ends thereof for mounting the same on the heddle supporting bars, said mortises being formed by slotting the strip from which the heddle is formed, leaving strips on each side of each mortise, and one of the strips' of each mortise being transversely slitted to permit the heddle being mounted on the'supporting bars without removing said bars from the frame.

2. A. heddle made from a thin, flat strip of metal having mortises near the ends thereof for mounting thevsame on the heddle taraeae by slotting the strip from which the heddle is formed, leaving strips on each side of each mortise, and one of the strips of each mortise being transversely slitted near one end thereof to permit the heddle being mounted on the supporting bars Without .is formed,'leaving strips on each side of each mortise, and one of said strips of each mortise being transversely slitted near the lower end thereof to permit the heddle-being mounted on the supporting bars without removing said bars from the frame.

' 1. A heddle made from a thin, flat strip of metal having mortises near the ends thereof for mounting the same on the heddle supporting bars, said mortises being located off-center with respect to the side edges of the heddle, to thereby provide stripson each side of eachmortise one of which is of appreciably greater width than the other, and the strip of narrower width being transversely slitted to permit the heddle being mounted on the supporting bars witnout removing said bars from the frame.

5. A heddle made from a thin, fiat strip J of metal having mortises near the ends thereof for mounting the same on the heddle supporting bars, said mortises being located d-center with respect to the side edges of the heddle, to thereby provide stripson each porting bars without removing said bars from the frame.

6. A heddle made from a thin, flat strip of metal having mortises near the ends thereof for mounting the same on the heddle supporting bars, said mortises being located off-center with respect to the side edges of the heddle, to thereby provide strips on each side of each mortise one of which is of an appreciably greater width than the other,

and the strip of narrower width being transversely slitted near the lower end thereof to permit the heddle being mounted on the supporting bars without removing said bars from the frame. I

In testimony whereof, I have hereunto signed my name. Y
