HEDDLE FRAME Aug. 7, i945.

'Filed July 12, 1944 Patented Aug. 7, 1945 UNITED STATES PATENT OFFICE Q mm" E George R.. Plott, near Concord. N. C. Application July 12, 1944, Serial N0. 544,476

8 Claims.

This invention relates to a heddle frame and more especially to a heddle frame having heddle bars for supporting the heddles therein, with means for releasably and detachably vmounting the heddle bars in the heddle frame so that they can be quickly inserted in place and quickly removed from the frame together with the heddles carried thereby.

It is an object of this-invention to provide in a heddle frame, means for detacha'bly mounting the heddle bars in a ilxed position so that the can be easily removed from the frame.

It is another object of this invention to provide .in a heddle frame having upper and lower bars and side bars connecting the same together to provide means whereby the top and bottom heddle bars can be detachably mounted on the vertically disposed bars at each end of the frame so that they ca n be'quickly mounted in position and quickly removed from the frame.

It is a `further object of this invention to proi vide means for detachably supporting the heddle bars in a heddle frame at each end thereof with supplemental means for also supporting the heddle bars at a plurality of points intermediate their ends.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawing, in which:

Figure 1 is `an elevation of a heddle frame Y equipped with my invention with the central portion thereof broken away;

Figure 2 is a vertical sectional view through the lower left-hand `portion of Figure 1;

Figure 3 is an elevation looking from along the line 3-3 in Figure 1;

Figure 4 is a vertical sectional view taken along I the line l-l in Figure 1;

Figure 5 is a vertical sectional view taken along lthe line S-lin Figure 1;

Figure 6 is a horizontal sectional view taken along the line .6 8 in Figure 1;

Figure 7 is an elevation 'of a portion of th lower left-hand corner of Figure 1, and showing the securing vcuil in elevatedgp'osition. Y

Referring morespeciilcallyto the drawing, the numerals I0 and IIindicate the upper and lower framemembers of a heddle frame, and these are relation. The upper bar I0 has ya pair of looped members I6 by means of which suitable straps from the bar II, but since theseare conventional,

they are not shown.

Secured in the bars I0 and II and projecting from proximate surfaces thereof are looped members I I having hooks I8 pivotallysecured at one end thereto and the other end being hooked as at I9 and being adapted to hook over heddle supporting bars 20. These heddle supporting bars are adapted to be detachably Supported at their ends on the vertically disposed bars I2 and I3 by means of notches 2I being cut in the sides of these rods I2 and I3, and these notches are restricted at their router ends or beveled inwardly so that the heddle bars 20 have to be slid endwise into these notches so that they cannot vloe pulled directly outwardly laterally of the notches. 'I'he heddle bars' 20 have in each end thereof a per-v foration or hole 23, and there are slidably mounted on the rods I2 and I3 cui members 25 which have outwardly projecting

ears

26 and 21 and also have a slot -28 therein. These cuff members are adapted to be slid outwardly, as for example, from the position shown in Figure '7 to the position shown in Figure 1, and suitable bolts 3| are passed through perforations 29 in the projections or

ears

26 and 21 which also penetrate the holes 23 in the ends of the bars 20 to thus `not only securely amx the ends of the heddle bars to the cuff members, but due to the fact that. the cui! members have a relatively close slidingt with the rods I2 and I3 they prevent any tendency for the bars 20 to have lateral movement while the cuil's-N are in the position shown in Figure l.

The heddle bars 20 vare adapted to support heddles l0 in a conventional manner thereon and only a few of these heddles 3 0 are shown as they are supposed tor extend all the way across the joined together by suitable bars or rods I 2 and I 3. 50

The bars I0 and II are held in spaced relation on bars I2 and I3 by means of'the.- ends of the rods or bars I2 and I3 being threaded and have ing suitable nuts I4 disposed above and-below frame 'for the entire length of the heddle bars 20 from posti2 to I3. A

When the nuts on bolts 3| are cutis 25 can be slid along their respective rods and in the drawing, thecuff is shown spaced from its associated rod, but when the nut on bolt 3| is driven home to bring the ears 26 and 2l against the opposed sides of the heddle I bar 20, it will bring the interior surface of the cuit 25 into clamping engagement with its associated rod.

the horizontal bars for holding theln'in spaced 55 Inthe drawing and specification, there has been loosened, the l set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. In a heddle frame having horizontally disposed frame lmembers and vertically disposed end bars disposed between the ends of the horizontal frame members, a .,pair of heddle bars, means for removably anchoring the ends of the heddle bars to the vertically disposed end bars comprising the vertically disposed frame members having cavities therein into which the heddle bars are adapted to t and cuff members surrounding the vertically disposed end bars and slidably fitting over the end s of the heddle bars, and means penetrating the slidable members and heddle bars for releasably locking the slidable cuff members to the heddle bars and to the vertically disposed end bars.

2. In a heddle frame for looms having horizontal frame members provided with end bars forming a part of the frame, said end bars having cavities in one side thereof, a pair of heddle bars whose end portions are adapted to fit in said cavities and slidable members mountedon the end bars and adapted to iltv over the ends of the heddle bars, and means for securing the slidable members to the ends of the heddle bars.

3. In a. heddle frame for looms having upper and lower horizontal frame portions, a pair of end bars having notches in one side thereof and joining the upper and lower frame portion of the frame together, a pair of heddle bars for supporting heddles, means for releasably anchoring the heddle bars to the end bars comprising members slidably mounted on the end barsand each having a slot therein adapted to t over a heddle bar and having a pair of lugs extending therefrom, the lugs and the`ends of the heddle bars having coinciding holes therethrough through which bolts are adapted to be passed to secure the members to the end bars and the heddle bars.
