5 Claims. (01. 139 92) f This inventionirelates to steel heddle frames, the primary object of the invention being'to provide. a heddle frame designed especially for use with sectional heddles.

.An important object of the invention is to provide a steel heddle frame including adjustable heddle bar supports which may be moved longitudinally of the heddle bars of the frame, to the end that the heddle sections maybe uniformly positioned throughout the length of the heddle frame. I

A further object of the invention is the provision of means whereby the adjustment of the heddle bar supports may be readily and easily accomplished without the necessity of removing the heddle bars thereon.

With the foregoing and other objects in view,

which will appear as the description proceeds,

the invention resides in the combination and arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the .scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational view of a heddle frame, constructed in accordance with the invention.

Figure 2 is an enlarged sectional view taken on line 2-2 of Figure 1.

Figure 3 is an end elevational view of the heddle frame.

Figure 4 is a sectional view taken on line 4 of Figure 1. a

Figure 5 is an enlarged detail View illustrating the means for securing the heddle bar to the heddle bar supporting rods, parts thereof being shown in section.

v Figure 6 is a side elevational view of the heddle bar supporting rod securing means, parts of the frame being shown'in section. 1

Figure '7 is a transverse sectional View through a heddle supporting rod.

Figure 8 is a fragmental sectional view illustrating the manner of securing the end bars to the upper and lower bars of the heddle frame.

Referring to the drawings in detail, the steel heddle frame forming the subject matter of this invention comprises an'upper bar 5 and a lower bar 6, the bars 5 and 6 being of channel construction, the open sides of the bars being disposed towards each'other.

As clearly shown by Figure 6 of the drawings the sides of the channel bars 5 and 6 are inclined inwardly, for purposes to be hereinafter more fully disclosedl Connecting the ends of the bars 5 and 6, are end bars I, vwhich have inwardly extended ends 8 that are formed with threaded openings that align with openings formed near the ends of the bars 5 and 6 for the reception of the screws 9, whereby the bars 5 and 6 are securely connected to the end bars of .the frame. Y

The end bars I are formed with openings near the ends thereof, the openings being elongated and of sizes to'accommo'date the endst iof the heddle bars ID, the heddle bars I!) being of lengths to extend beyond the end bars 1 where they are provided with'openings, to receive the ends of the heddle bar retainers II, that are carried by the end bars 1.

The heddle bar supporting rods are indicated by the reference character I 2, and each of these rods is formed with threaded ends l3, on which the clamping members 14 are mounted, the clamping members l4 being held in position by means of the heads I 5 formed at the extremities of the rods I2.

These clamping members M are formed of sheet metal material and have sloping sides conforming to the shape of the bars 5 and 6, and are so constructed that they will closely fit within the channels of the bars 5 and 6, as clearly shown in Figure 6 of the drawings.

, Cooperating with the inner clamping members I 4'are outer clamping members l6, which are also formed of sheet material and shaped to conform to the shape of the bars 5 and 5, the outer clamping members being of widths to embrace portions of the outer surfaces of the channels.

Positioned on each threaded end of each heddle bar supporting rod [2, is a nut H, which nut, is adapted to be rotated to move the outerclamping member l6, associated therewith into clamping relation with the inner clamping member, to the end that when the nuts I! have been properly positioned, the heddle bar supporting rods will be securely held in their positions of adjustment longitudinally of the bars 5 and 6 of the frame.

Thus it will be seen that due to this construction, sectional heddles may be positioned on the frame, and the heddle bar supporting rods may be positioned so that the heddle bar support- 0 Pivoted clips l8 are carried by the heddle bar supporting rods, and are formed with openings to receive the heddle bars l0, whereby the heddle bars may be readily and easily secured to the heddle frame.

Eye bolts indicated at 19 are secured to the heddle frame and provide means whereby the heddle frame may be supported.

Having thus described the invention, what is claimed is:

1. A heddle frame comprising upper and lower. channel bars having their open sides disposed towards each other, heddle bar supports including rods disposed between the upper and lower bars, clamps at the ends of the rods, each clamp comprising an inner member and outer member, the inner member being disposed within the channel bars, the outer member cooperating with the inner member in clamping the channel bars, and means for securing the clamps to the channel bars.

2. A heddle frame comprising upper and lower channel bars, heddle bars forming part of the frame, heddle supporting rods, clamps at the ends of the heddle supporting rods, said clamps cooperating with the channel bars in securing the heddle supporting rods in their positions of adjustment longitudinally of the upper and lower channel bars, and means for removably securing the heddle bars to the supporting rods.

3. A heddle frame for supporting sectional heddles, comprising channel bars having their open sides disposed towards each other, the flanges of the channel bars being inwardly inclined,

heddle bars, heddle bar supports disposed between the channel bars, clamping members at the ends of the heddle bar supports and including plates conforming to the shape of the channel bars to clamp the channel bars, means for securing the clamps in their positions of adjustment to hold the heddle bar supporting rods in their positions of adjustment, and means for securing the heddle bars to the heddle bar supporting rods.

4. A heddle frame for supporting sectional heddles and comprising parallel bars, means for holding the parallel bars spaced apart at their ends, heddle bars, heddle bar supporting rods disposed between the parallel heddle bars holding the bars spaced apart intermediate the ends of the bars, clamps at the ends of the heddle bar supporting rods, clamping the first mentioned parallel bars and securing the heddle bar supporting rods in their positions of adjustment, and means on the heddle bar supporting rods for securing a heddle bar thereto.

5. A heddle frame for supporting sectional heddles, comprising parallel channel bars having their open sides disposed towards each other, heddle bars, heddle bar supports disposed between the channel bars, clamps at the ends of the channel bar supports and fitted within the open sides of the channel bars, clamping the channel bars and adjustably securing the heddle bar supports to the channel bars, and clamps on the heddle bar supports and adapted to clamp a heddle bar, securing the heddle bar to the heddle supports.
