DIVIDED LOOM REED.

' BIVIDED LoonLRnEn.
To all whom it may concern Be itv known that l, CARL h'l omcsn, a subjcct. of the Emperor of Austriallungary, residing at Arbon Switzerland, have invented new and useful improvements in Divided Loom-Reeds; and I do hereby declare the following to be a full, clear, and exact description of the invention. such as ill onable others skilled in the ar to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or gares of relerence marked thereon, which form a part of this specification.
The invention relates to a divided loomrced in which one set .of teeth is movably arranged so that it may move away from or against the other set of teeth. This type of reeds as hitherto constructed possesses the drawback that by the thread guide of the shuttle the weftis in'serted through the open reed behind the sets of teeth of the latter. Since during this operation the reed must open very far in order to allow the thread guide to pass, it happens when the shed is formed that warp threads especially if they have knots do not fall into their proper tooth spaces but stick to adjacent warp threads and are taken by them into their tooth spaces. Since in such reed also in the open position of the reed the lower movable set of teeth does not release the warp threads, it happens that the warp threads especially if they have knots, are caught, by the knots in the tooth spaces so that the forming of the shed does not take place as it ought to do. In consequence of these drawbacks fabrics of interior value are produced, or the threads sticking to each other or caught in the tooth spaces are torn or cut. by the thread guide.
The object of the present invention is to :ta-ovide a divided loomreeu of the type re- .crrcd to in which the weft is inserted in the vellkuown manner in front of the sets of teeth. In order to avoid the above men tioned drawbacks the movable set of teeth being carri d by a member pivot ally mounted on the reed carrier supporting the other set of teeth is moved with relation carrier each time when the ree. i" 0 so that it wholly releases the while they mo ve into the open. she... position.

tion by way of example, Figure 1 shows a. vertical section through the reed. Fig. 2 shows a longitudinal section through the same. Figs. 3 and t are side elevations showing the reed in two dili'ereut working positions. Fig. 5 shows parts of :1V loom with a reed according to this invention and a mechanism for actuating the reed.
The reed is provided with an upper plate 1 carrying a downward projecting set of teeth 2 and with a lower plate 3 carrying an upward projecting set of teeth 4. The lower set of teeth is arranged behind the upper set. and the teeth of both sets cover each other for a certain amount. The plate 1 is arranged between the arms of a forked *arrier and mounted to turn about pivots (l. The plate is held in working position by means of a pin 7 the point of which is pressed by the action of a spring into a notch 8 provided in thc'carrier 5. By means of screws the plate is secured to" is arranged between the 5 and mounted to turn The reed carrier 5 a fixed axle 11. block 12 against a cylindrical portion 5 laterally projcctiiiig from the carrier (Figs. 2 and The carrier 5 is oscillated from a disk 13 which is mounted on the loom (Fig. 5 and provided with a cam slotli. The disk 13 is rotated by any suitable means which are not shown on the drawing. A roller mounted on the lever 15 is guided in the slot. and a link 16 connects the lever 15 to the axle 17 (Fig. 5). The axle 17 is secured to projections of the member 10 and projects through openings 5'7 provided in the arms of the bracket- 5. The openings 5 are of larger diameter than the axle 17. The warp threads 18 are guided through the teeth. finished ribbon.
The described reed when mounted on a ribbon loom operates as follows: Fig. 1 shows the reed carrier in its upper position of rest, that is the position in which the shuttle inserts the weft 19 into the open shed. The reed is closed so that. the teeth of bo h sets touch each other. l'Vhen the shuttle has pas the teeth the inserted.

Vv'hcn th alter the lir: is lower s of ie car-.1 a of hegotating c 13, for the first time the A spring presses a. brakol9 designates the weft and 20 the a member 10 which 7 carrier is not moved but only the member which is turned downward with the lower set of teeth as much as the play between the axle 17 and the openings 5 allows such movement. The reed is opened hereby, that means the lower set of teeth is moved away from the upper set so that a space is left between both sets of teeth (Fig. 3). As soon as the axle 17 touches the lower wall of the openings 5 alsothe carrier-.5 and therewith both sets of teeth are moved downward whereby the weft 19 is moved through said space behind the upper set of teeth (Fig. 4). When thereafter the link 16 is raised by the disk 13 in consequence ofthe play between axle 17 and the openings 5 at the first time only the member 10 is turned upward about the aiile 9 whereby the lower set of teeth 4 is moved against the upper set 2, that means the reed is closed, as shown in dash and dot lines in Fig. 4. After the axle 17 has touched the upper wall of the openings 5" also the carrier 5 is moved upward whereby the inserted weft 19 is pressed by the lower set of teeth against the finished portion 20 of the ribbon. The described operation is repeated at every insertion of a weft. During all this operation the carrier 5 is braked by the block 12 so that it performs no undesired motion and is prevented from being driven by the member 10 when moving alone.
With the reed according to this invention the weft is inserted in front of the lower set of teeth and the latter when the reed is opened is moved so much downward that tooth space of the lower set of teeth. Here-- by both the threads are prevented from being torn bythe thread guide of the shuttle. Moreover since the lower set of teeth moves to and fro like a rake a warp thread which carries a knot is prevented from being ,caught in a tooth space so that there is no danger also with such thread that the forming of the shed is interrupted;
n order to clean both sets of teeth, by
set of teeth away from and against said sec 0nd set of teeth in such manner that when the reed is opened the movable set is moved independently of the carrier so that it wholly releases the warp threads moving into the open shed position.
2. In a divided read a movable of teeth, a second set of teeth, a reed carrier supporting the second set of teeth,-a member pivotally mounted on said reed carrier and carrying said movable set of teeth, an axle secured to the said member the reed carrier having openings through which said axle passes of larger diameter than the axle, and means for. reciprocating the axle.
3. In a divided reed a movable set of displacing the pin 7 from the notch 8 the teeth, a second set of teeth, a reed carrier so supporting the second set of teeth,-a memberpivotally mounted on said reed carrier and carrying said movable set of teeth, an axle I secured to the said member, the reed carrier having 0 enings through which said axle passes 0 larger diameter than the axle, means for reciprocating the axle and means for exerting a braking action on said. reed carrier.
In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
