PATENT OFFICE.

Tenter frames are used to dry fabrics, especially curtains, on which the curtains are stretched and on which they have been stretched for so long be left until they are sufficiently dry. To the frames covered with curtains Side so that they occupied himself with the covering of new frames Workers are not in the way, it has often been suggested, the same for a higher one To create a place where they are better exposed to the circulation of heated air. That Transferring to a higher place and recovering is the same as before Method a very cumbersome one, since you use ladders or steps here and the Fixing and loosening of the frame in the higher position always had to be done by hand, What manual work required a whole number of people.

With the help of the present device, a single worker is able to work in one Room with a footprint that does not significantly exceed the area of a single frame, to take a larger number of frames into use and each frame is extremely easy to use in any position.

The frames placed on top of each other on the floor before using the device are individually turned into one for covering with curtains by simply turning a crank brought a suitable position and after covering in such a height by further Turning the same crank lifted, so that the lower frame is also in the right position can be brought and comfortably covered. Provision has still been made that the strung ones The height of the frames are so far apart that the appropriately warm air can pass freely between them and can absorb as much moisture as possible.

Fig. Ι the accompanying drawing shows the device in side view and -Fig. 2 in Cross-section, Figs. 3 to 6 show details.

^{The frames r 1} to r ^{6 to} be covered with curtains or other fabrics are perpendicular between the appropriately arranged in pairs. Post χ (Fig. 1 and 2) out, which are connected by the crossbar y to form a fixed frame. To move the frame r up and down, a winch k is used, which can simultaneously wind up several, expediently four, ropes, cords, chains or the like. According to the number of posts χ . The ropes g are guided over rollers in such a way that they hang down from the pillars χ , and at the outermost ends they have hooks h (Fig. 6), which are able to grasp the frames r on the pins i and which are all always at the same height are located. In order to ensure the uniformity of this altitude, the ends of the ropes are still loaded with weights Z, which are guided by rails or perpendicular rods η . Is expedient. the connection is made in such a way that pins Z ¹ sit on the weights I , to which on the one hand the ropes g are attached by means of intermediate links m and on the other hand the hooks h hang. The hooks h are designed on one side (FIG. 6) in such a way that a lateral extension h ¹ is created which has a lower inclined surface u and an upper inclined surface s (FIG. 5). If the hook is free, the hook cavity is perpendicular to the pin i the

Claims (1)

Clamping frame in such a way that when passing this pin, only the attachment h ^{1 of} the hook can come into contact with the same. If the hook cavity is to the left of the hook body, the lowest end of the lower inclined surface u is on the right and the uppermost end of the upper inclined surface s is to the left of the perpendicular center line drawn through the pin i (FIG. 5). This enables you to grasp, raise, lower and release the frame by turning the winding crank in one direction or another in good time. To grasp the frame, the hooks must be lifted over the pins /. By moving the hooks downwards, the surface u slides along the pin and moves the hook to the right until the pin can be inserted into its cavity. During the upward movement that then follows, the hooks take the pegs i with them, so that the frame can be raised or lowered into any position. · If the hooks are to be released after the frames have been set down, the hooks only need to be lowered slightly. In doing so, the hooks slide past the pegs until they have passed the uppermost tips n> of the approaches h ^l . The hook can then be lowered or raised as desired without a new intervention being made; During the upward movement the surface s of the attachment h ¹ slides along the pin so that the hook passes it on the left. Such automatically lifting and lifting hooks of similar construction are known per se (see patent specification No. 65988), but not in their use for the present purpose and in connection with the other means offered in the claim. To fix the frame in its highest position, each frame corner is equipped with a pawl α (Fig. 3 and 5), which are rotatably attached to the ends of the frame crossbars guided between the posts χ by pins a ^1. These pawls a, for each of which a support piece c is provided on the post χ of the frame xy , have extensions beyond their pivot point on which a lateral extension a ² equipped with inclined surfaces 0 and ν is provided (Fig. 3 and 4) . The inclined surfaces 0 and ν of this approach have a similar purpose as the inclined surfaces u and s of the hook h. These come into effect in connection with a spring b seated on the frame in such a way that during the upward movement of the pawl the inclined surface 0 of the projection a ^{1 is} grasped by the spring and the pawl from the position shown in dotted lines into the full position Lines shown is rotated. Here, the tip of the pawl α is inserted into the support extension c and, when the pawl or the frame is released shortly thereafter, finds a support on the extension c. If the frame is to be lowered, it is raised so far that the point of the spring b is the lowermost point x ^{1 of} the attachment a? and the pawl can swing into the dotted position shown in Fig. 3. In order to make this easy to do, the center of gravity of the pawl a lies to the left of the pivot point in the positions shown in FIG. 3, the lower part ^{1 of} the pawl α being suitably heavier than the upward extension a ° . The movement is limited by the stop pin d and the pawl is held in such a position that the tip x ¹ lies to the left of the spring tip. If the frame is now lowered, the spring must slide past the surface ν of the ^{extension a 2} without further rotation of the pawl, so that the frame is not hindered in its downward movement. With the apparatus described above, one is able to bring the frames r ¹ to r ⁶ (FIGS. 1 and 2) lying on one another on the ground one after the other into the position suitable for covering and then to a height such that they are not a hindrance when covering the lower frame. The distance between the frames from each other in the maximum position r ¹ to r ⁶ can be precisely determined by a suitable choice of construction and depends on the local nature of the room or. according to the possibility of creating a suitable air vent or air circuit. Patenτ claim: Device for tensioning and drying fabrics, in which by means of a winch or a number of tenter frames can be raised and lowered individually in a similar device can, characterized in that the elevator ropes operated by the winch are shaped in this way Have hooks that the frames can be made by simply lowering and lifting the elevator ropes can be individually grasped by the hooks and lifted to any height, with the frame at the highest point the device can be set by locking devices, which also by suitable lifting and lowering of the individual frames by means of the winch released respectively. coupled can be. 1 sheet of drawings.
