To all 1071 0122 it may concern:
Be it known that I, G'UmoHoRN, engineer,
- a more uniform thread tension actsfupon i the brake of the reel'or spool in such a inanner that the brake is released in a degree corresponding to the tensionof the'thread. Further it is well li'nownto have athread guide acting upon the drive otthe spool spindle so that the drive is stopped as soon as the thread is finished,
breaks'or its free-delivery is impaired. l I
The object ofthe present invention is to. provide a jack-frame or spooling machine in which all these problems are solved in unison the thread passing rounda movable guide member which under the tension of the thread on the one hand for obtaining a constant thread tension controls the brake" of the delivery reel 0r spool and on the other hand causes the brake to operate when the thread is finished or breaks, so that the delivery spool or reel is prevented from running further, and moreover operates the stopping device of the Wind up s 001 to stop instantly the winding up and iurthermore disconnects the spool spindle in thev moment when on account of a disturbance of the free delivery of the thread from the storage spool or reel the thread tension exceeds a certain amount. The uniform action of the reel or spool brake and the quick and reliable action of the stopping device make the invention especially useful for shed spool machines.
In the accompanying drawings v Fig. 1 shows diagrammatically a front view of a jack-frame according to the invention.
Fig. 2 is a side view and Fig. 3 shows an arrangement of the stopping device suitable in case delivery reels are used instead of storage spools.
The delivery spools a are journaled in the I frames 1' of the delivery devices. Each thread leaving the spool is passed over a thread guide 6 acting upon the brake of its spool in such a manner that it opposes always the same resistance against the delivery of th'e'thread'. By "the tensionspring 7" each thread guide iskept under "a power corresponding ,to the desired tension of the The spools areprovided each with a brake disc 3 (Fig. '2) surrounded by a brake band. 'IOne end of each brake band is'securedto *tlie frame 1 and spring actuated tension levers h act upon its free end; The shaft of eachthread tensioning device is prov dedwith acam e which onliitlng of the thread "guide b presses against a brake releasing lever transferring the pressure to ftha'brake 'tensioning lever 7L, whereby the braking action is reduced and finally be Fig. 2 shows'the positionof the thread guide which it has during the spooling operation-with small oscillations. By means of "a rod g'the thread guide is connected to the disengaging or stopping device in such a manner as to cause releasing of the thread guard to by a downward rocking which until now was realized 'idire'ct'ly by the thread as "soon as th'e s'tor'a'ge spool emptied or the thread was broken whereby thestopping device becomes operative in known manner.
In order to cause each thread to follow always its distinct separate course it is passed through a guide ear Z arranged at suitable spots. In order that the thread may run over its guide, arm always from the same point each thread is led first from the storage spool or reel over the rock shaft of the thread guide, the remaining course is clearly shown in the drawings.
In the described jaclnframe or spooling machine no thread breaks by starting the spool spindle because each thread at once causes its delivery reel to start. Firstly the tensioned thread guide is lifted completely releasing the brake of the delivery reel which thereupon is capable of revolving as easily as the friction of .its layers of thread allows so that its inertia. only is to be overcome. On the other hand the brake instantly acts with its full power assoon as it is disengaged from thread guide according to a reduction of the thread tension when the delivery reel is emptied or the thread breaks.
From the beginning to the end of the spooling operation each thread has the tension received by its guide arm. If the resistance of the delivery reel or spool in- Ell) creases with the reduction of its diameter the brake simultaneously is further released correspondingly whereby the increased resistance of delivery in neutralized again.
The device represented in Fig. 3 stops the spooling machine also when the tension of the thread increases over a certain limit, for
instance if the thread is prevented fromrunning freely away from the reel. Then the thread lifts its guidearm b and with it the rod 9 engaging the lever w, which is coupled to a second releasing hook w". The
' latter swings to the left and engages the actuating the stop-ping device when the thread runs out or breaks.
2. In a spooling machine, a thread guide, a delivery spool, a brake acting'upon the delivery spool, a stopping device, said guide,
controlling said brake in accordance with the tension of the thread and releasing the brake to act upon the delivery spool and actuating the stopping device when the thread runs out or breaks, and means actuating the stopping device when the tension of the thread exceeds a predetermined limit. 3. In a spooling machine, a delivery spool, a thread guide, a brake acting" upon the delivery spool, a stopping device, and means connecting said thread guide to said brake and to said stopping device.
4:. In a spooling machine, a delivery spool, a windup spool, a'thread, a brake acting upon the delivery spool, a stopping device, and means controlled by the thread guide adjusting said brake according to the tension of the thread and operatlng the stopping device when the thread runs out or breaks or the tension of the thread exceeds a predetermined limit.
5. In a spooling machine, a delivery spool, a wind upspool, a thread guide, a brake acting uponthe delivery spool, a stopping device, a cam fixed to the'thread guide controlling said brake, and means connecting the thread guide to the stopping device.
' 6. In a spooling machine, a delivery spool, a thread guide, a brake acting upon the delivery spool, a stopping device, a cam fixed to thethread guide controlling said brake, a rod connecting the thread guide to the stopping device, and means on said rod releasing the stopping device for operation when the thread runs. out'or breaks or the tension of the thread exceeds a predetermined limit.
In testimony whereof I have signed my name to this specification.
