No. 769,115 Claims priority, application Austria Oct. 28, 1957 9 Claims. (Cl. 139-92) This invention relates to a harness frame for heddles with U-shaped hook ends for looms.

In accordance with the invention, means are provided by which the heddles as a whole, held together by a special member, are insertable into the frame and removable therefrom in transverse direction to the plane of the frame.

By means of the invention it is possible for a set of heddles to be taken off or introduced into the frame, without the heddles falling out of place when taken off.

Further features of the invention will appear from the following description and claims, taken in conjunction with the accompanying drawing, wherein there are shown some forms of heddles incorporating the invention.

In said drawing:

FIG. 10 is a side View partly in section showing a form, in which, by a bayonet-joint, the heddle guide rail is removable from the frame and insertable therein in transverse direction, the rail being double hooked for receiving two sets of heddles arranged one behind the other.

FIG. 11 is a front view partly in section of FIG. 10;

FIG. 12 is a detail to FIG. 11;

FIG. 13 is a detail view, in which the heddle guide rail is formed of two parts, and

FIG. 14 is a corresponding front view.

Referring more particularly to FIGS. 1-7, heddle frames are shown having heddle guide rails 2 separate from support rods 1, the rails 2 being movable towards each other to liberate the hooks 6a of the heddles 6 from the hooked rails 2. Thereby only one rail, for instance the upper one, can be displaceable downwards; but both rails 2 may also be displaceably supported in the frame to enable them to be moved relatively to each other for the purpose of liberating the heddles 6. When liberated at their hooked ends 6a, the heddles 6 can be lifted off very easily in transverse direction to the plane of the frame. Such heddles can also be readily re-inserted by laying them onto the rails 2 which are moved towards each other and then again from each other so as to cause the rails to engage below the hooks 6a of the heddles 6 and to secure them against falling out.

In the forms according to FIGS. 17, the freeing of the heddles 6 or their hooking thereon and securing in the guide rails 2 takes place in the manner as generally shown in FIGS. 2 and 3. In the working condition, the heddles 6 with their hooks 6a are hung into the rails 2 by their U-shaped form (FIG. 2). By displacing one or both rails 2 by a relative movement towards each other, the hook 6a of each attached heddles 6 will be free so as to permit the heddles 6 to be lifted off in transverse direction to the plane of the frame. For re-inserting them the opposite procedure applies (FIG. 3), whereby the rails 2 being again spaced from. each other so that the hooks 6a of the heddles 6 and the hook of the rail 2 engage with each other (FIG. 2).

The freeing and removal of the heddles in the aforedescribed manner has a really practical meaning, since the freed heddles can be removed as a unit, without falling apart. They should likewise be capable of being reinserted as a unit. This purpose is achieved by one member which holds the heddles together and said member is exemplified in FIGS. 2 and 3. Towards their ends, the heddles 6 each have an aperture, say, in the form of a circular hole 6b. Through said holes, the heddles can be assembled, as on a rod or wire 20; on being freed by moving them relatively towards each other on the wires arranged in rows, the heddles can be readily removed from the frame and just as well be re-inserted therein.

In the embodiment according to FIGS. 4 and 5, displacement of the heddle guide rail 2 is effected by means of one or more angular guides 5. These angular guides 5 are disposed as slots, each in a lug 4 of a part 1a formed in the support rod 1. The rail 2 has rigid with it bolts 3 which engage the slots 5, thus carrying the rail 2 displaceably on the support rod 1; 1a, 4. The angular guide 5 has a horizontal portion and an adjoining vertical portion as a bayonet slot. Located in a piece 22 attached to the side strut 21 is a spring 23 which, together with a similar but stronger spring provided in the opposite side strut (not shown), fixes the lateral position of the heddle guide rail, in which the bolts 3 are pressed against the end of the slots. FIG. 4 shows the rail 2 in working position, i.e. in that as shown in FIG. 5, in which the heddles with their hooks 6a are hung in the hooks of the rail 2. For releasing the heddles, the rail 2 with the bolts 3 is pushed to the right, until the bolt 3 falls into the vertical section of the slot 5, permitting the rail 2 to be lowered to that extent and to come nearer the opposite rail 2 so as to free the heddles as shown in FIG. 3.

In the form according to FIGS. 6 and 7, the displacement of the heddle guide rails or its adjustment to the opposite sides takes place in the following manner:

According to FIG. 6, the rail 2 is in the position in which it frees the heddles. On the other hand, FIG. 7 shows the working position. In the form according to FIG. 6, the angular guide 7 is of a design somewhat differing from that according to FIG. 4. The guide slot 7 essentially consists of an oblique slot with two rests 7a, 7b lying outside the aXis at an angle thereto, in which the bolt 3 on the rail 2 can engage. Said rests determine the upper and lower positions of the rail 2. In order to push the bolt 3 of rail 2 into one or other rest, there is provided a coil spring 9 supported between the part 1a of the support rod 1 and the rail 2. Said spring 9 engages the projection 8a punched out of

rail

2, and 1b in the part 1a. The springs 9 have the tendency to urge the two

parts

1, 1a, and the part 2 apart.

To move the rail 2 into the upper position, it is sufficient to raise it against the pressure of the springs 9, until it falls into the upper rest. In the upper rest, the rail 2 is in its working position, in which the hooks of the heddles are secured against displacement.

With the form according to FIGS. 6 and 7 one obtains I a displacement or relative approach of the rails, in order to free the heddles, just as With the form according to FIGS. 4 and 5.

In the form according to FIGS. 8 and 9, the

support rod

1, 1a together with the rail 2 rigidly attached thereto is displaceable in the manner as in FIGS. 2 and 3. Therein the rail 2 is welded to the part 1a of the support rod at the points 14. Situated within the hollow support rod 1 at each end is an adapter piece 11. The support rods are mounted on the side struts by means of screws 12. The screws 12 each pass through an elongated hole 13 in the side strut 10 so that, upon loosening the screws, the support rod 1 and rail 2 can be bodily displaced in the elongated holes and be fixed again in the respective displaced position. A rest 13a for a collar 12a of the upper screw 12 serves for securing the upper or working position. With this screw firmly in place, the

connection

12a, 13a secures the angular joint. To displace the support rod 1 together with the rail 2, the upper screw 12 must be backed out until the collar 12 clears the rest 13a.

With the heddles assembled and united in a set by the wires 20, the rails 2 can be withdrawn so that the heddle set can be removed laterally from the frame. Similarly, the heddle set can be reinserted by pushing the rails '2 into the hooks 6a thereof.

FIGS. 10-12 illustrate a form, in which the rail (together with the heddles hooked on) is removable and reinsertable in a lateral direction to the frame. Provided at the lower end of the support rod part 1a are longitudinal slots 1b engageable by suitable hooks a of a rail 15. In the present instance, this is shown on a rail with double hook 16. The slot 1b is somewhat longer than the hook 15a and the latter has a nose 15b which is capable of gripping behind the corresponding part of the

support rod

1, 1a.

In FIG. 11, the rail 15 with the hooks 15a is hung in transverse direction into the slots 15. To secure this position, the rail 15 is moved somewhat to the left until the nose 15b grips behind the part 1a (FIG. 12). This is the working position of the rail 2, into which the heddles are hung.

To remove the rail 15 together with the heddles assembled thereon, in the illustration the rails are pushed somewhat to the right (FIGS. 11 and 12) so that the hook 15b no longer hinders the rail 15 from being transversely removed with the heddles.

In the form according to FIGS. 13 and 14, removal of the heddle set in transverse direction is possible in that the hook-shaped heddle guide rail comprises two parts 2a and 2b, part 2a of which is rigid with the

support rod

1, 1a, whereas part 2b is slidably guided lengthwise on the stationary part 211. For this structure, the fixed part 2a, at some places, has hook-shaped guides 20, between which and the cranked bottom edge of the part 2a with the movable part 2b and with the lower crank is guided lengthwise. In order to free the heddles 6 with their hooks 6a, the movable part 2b of the rail 2 is displaced endvvise and removed from the heddle frame. The heddles assembled in a set on a wire 29 may then be lifted off in transverse direction to the plane of the heddle frame. For replacing the heddle set, it is placed again onto the'frame and the rail 2b is pushed under the hooks 6b so that the heddles will again have their normal guidance, ensuring them againstfalling out.

By means of the invention, a device on heddle frames is provided by which the heddles, as a set, can be removed from the re-inserted into the frame in a simple and expeditious way. It is understood that the foregoing detailed description is given merely by way of illustration and that other variations may be made therein without departing from the spirit of my invention.
