To BIGELOW-SAN- roan cARPn 00., me, or THOMPSONVILLE, CONNECTICUT, A CORPORATION or MASSACHUSETTS TAKE-UP MECHANISM FOR LOOMS Application filed November 28, 1928. Serial No. 322,379.
This invention relates to looms and is more particularly directed to-mechanism for taking up'the cloth as it is woven.
It is now the ordinary practice to provide looms with a take-up mechanism at one side thereof for driving a take-up roll over which i the fabric passes, and such mechanisms have been effective in taking up the cloth during the weaving operation where the loom itself '10 has not been of unusual width. During recent years, however, there has been a constantly increasing demand for wider and wider fabrics, especially heavy fabrics such as carpets, rugsand the like, and in answering this demand problems have arisen with'respect to the cloth take-up mechanism due to the usual length of the take-up roll which is liable to partake of a torsional displacement or twistwhen driven at one end. r In accordance with the present invention, the take-up roll is driven at both ends by trains of mechanism each of which includes a worm and worm wheel connection between the ends'of the take-up roll and the actuating- .25 mechanism. It may happen at times, however, that the take-uproll is to be reversely turned to let-back and thereafter restored to its take-up position, or one of the trains of mechanism may become functionally inoper- .ative-at times; wherefore the present invention further providesa one-way or flexible connection between the worm wheels at each side of the loom and the ends of the take-uproll, all of which will be more fuly disclosed by the following description and the accompanying drawings of one good, practical form of the invention.
Inthedrawingsjz p Fig. 1 is a perspective view of a wide loom .for weaving heavy fabricssuch as carpets, rugs and the like; and provided with the "present invention;
Fig. 2'is a section longitudinally of the take-up roll,showing more particularly the one-way drive connection between the worm wheel and take-up roll;
Fig. 3 is a detached detail showing one form of ratchet and pawl mechanism for actuating the worm;
Fig. 4 is a sectional elevation showing a modified form of the invention;
Fig. 5 is a sectional front elevation showing the modified form of drive between the worm wheel and take-up roll; and
Fig. 6 is a section on the line 6-6 of Fig.4.
The loom frame may be of any usual construction and as shown comprises the side frames 1 between which is mounted the lay 2 having the reed 3 through which pass the warp threads 4, it being understood that the warp threads are themselves controlled and separated for the shedding operation by suitable shedding mechanism which, however, forms no part of the present invention.
A Mounted in suitable bearings 5, one at each side of the loom, is the take-up roll 6, which may be of the spiketype the axis of which at each side of the loom extends outwardly, as
indicated in Fig. 2, and loosely mounted on a portion 7 of the take-up roll axis at each side of the loom is a worm wheel 8which meshes with a suitable worm 9 secured for rotative movement upon the worm Shaft 10 which may be conveniently supported in suitable hearings 11, as indicated in Fig. 1.
The worm shaft 10 has secured thereto a gear 12 which may be driven by a train of mechanism actuated from a going part of the loom. In the form of the invention indicated mounted in one of the brackets 11 and itself driven by a gear 14 mounted upon the shaft 15, the relative sizes of the gears being such asto impart to the worms 9 at each side of the loom the desired speed to be transmitted to the take-up roll, as will presently appear.
Secured to the shaft 15, Fig. 1, is the ratchet wheel 16 which maybe actuated step-by-step by a pawl 17 mounted upon the pawl carrier by Fig. 1, the gear 12 is in mesh with a gear 13 18 and loosely supported about the axial cen ter of the shaft 15. The pawl carrier 18 has connected thereto the link 19 which is given its actuating movement, as shown in Fig. 1
7 by al ver 20 pivotally mounted at 21 to the side frame of the loom and connected at its rear end to a bell crank lever 22 supported for rocking movement on the stud shaft 23. In the present instance of the invention, as
indicated in Fig. 1, the rear end of the lever 20 is provided'with a pin 24 which engages a slot 25in thebell crank lever 22, and the latter itself may be given its rocking movement through a link 26 from any suitable gooing part of the loom, the construction being such that as the lever 20 is actuated, as hereinbefore described, the pawl 17 will turn the ratchet wheel 16 step-by-step to thereby impart rotative movement to the worm 9 through the train of mechanism described. 'Io prevent retrograde movement of the ratchet tion contemplates a one way power transmission connection between each of the worm wheels 8, one at each side of the loom, and the take-up roll. I
As shown in Figs. 1 and 2 of the drawings, such one way power transmissionconnection comprises a ratchet wheel 30 secured to each end of the take-up roll 6 and circumferentially related to the ratchet wheel 30, as shown, and eachof the worm wheels 8 is provided with a pawl carrying portion 31 in which is mounted a series of pawls 32for engagement with the ratchet teeth, of the ratchet wheels Obviously there may be any number of pawls 32 but since heavy fabrics, such as carpets,-rugs and the like are to be woven, it is desirable that there be a plurality of pawls 32, the'opposite pawls being so related to the ratchet wheel 30-as to be inactuating engage- :ment therewith,"whiletheremaining pawls of the series may remain inactive,.as indicated in Fig. 1. Each of the pawls 32 may comprise a toothed portion 33 and an upwardly extending stem 34 about which is mounted aspring' 35 normally acting to move the pawls inwardly into operative engagement with the teeth ofthe ratchet wheel 30.
' As more clearly shown in Fig. 1, two of the pawls',' one above and one below the take-up roll-6, are operatively engaged with the teeth of the ratchet wheel, while-the remaining pawls are idle. By this-construction it will be apparent that should the take-up roll 6 be turned slightly in a frontwarddirection, one
or more of the pawls will be operatively engaged with the teeth of the ratchet wheels,
thereby obviating any substantial lost mo-- tion. e
Each of the ratchet wheels 30, one at each end of the take-up roll, may be secured to the roll by anyappropriate means, but as shown 7 they are secured to the take-up roll by a key 36, although, of course, this manner of securing the parts together for turning movement in unison may be variously contrived.
, From the construction described it will be apparent that upon actuation of the worms 9,
' one at each side of the loom, the associated worm wheel 8 will be turnedlandthrough the one way power transmission between the worm wheels 8 and the ends'of the take-up roll, the latter itself will-be correspondingly turned to take up the cloth a during the weaving operation.
I The invention asdescribedprovides a positive drive for each end, of the take-up roll which obviously may be of the sand or spike roll type, with the result that all torsional twist of thetake-up roll under the heavy stress ofthe fabric will be avoided As hereinbefore noted, it may happen at tin esthat thecloth a is to be let back by reverse rotative movement of the take-up ,roll and then restored to position the fell of the cloth for the lay beat-up, or one of the takeups may become functionally ineffectual at times. In either event and notwithstanding I that the take-up roll is actuated through a worm and worm wheel at each end, rotative movement of one at either side of the loom will serve to take up the cloth by reason of the one way-power transmission between the worm wheels roll.
Mounted upon the worm shafts 10, one each side of the loom, is a hand wheel 37 whereby the cloth roll 6 mayhave let-back I movement imparted thereto by hand manipulation upon disengagement of the pawls 8 and'the ends of the take-up;
17 and 27 from theirjassociated ratchet wheels l6. ,Similarly, the take-uproll may be given its'take-up movement from either' side ofthe loom through the hand wheel 37,
by reason of. the one way power transmission connection between the worm wheels 8 and the take-up roll..
f Thus it will be obvious that the present invention not only provides for a positive: drive for the take-up roll at each end thereof through a worm and worm wheel connection which acts as a look as usual,but should either of the drive mechanisms fail tofunction at any time the take-up roll maybe actuated by i, c the other, notwithstanding the worm and worm wheel drive and lock 'at each end ofthe roll.
- In the form of the invention shown and described with respect to Figs. 11, 2=ai1d 3,
the drive for the ends of the take up roll has wheel 8 is a toothed member, 38 which may be approriately secured to the associated worm wheel 8 by bolts or similar means 39,
'therewith. In the present instance,
as indicated in Fig. 5. The toothed member 38 has a series of teeth 40 extending radially thereof to a more orless degree, and associatedtherewith is the opposed toothed disk 41 similarlyprovided with radial teeth and mounted on the end of the take-up roll at each" end thereof for rotative movement v shown in'the modified form of the invention,
the end portions of the take-up roll 6 are slabbed' off, as at 42, Fig. 6, to engage a corresponding opening in the toothed disk 41 wherebythe latter is caused to be connected to: the take-up roll for rotative movement therewith," andinterposed between a collar .43 at each end of the take-up roll and the 6 Figs. 1,2 and 3, each of the worm wheels 8 is operatively engaged with a worm -9 mounted on the worm shaft 10 which may. be driven through a train of mechanism 45,
46 and 47 Inthe'modification as indicated in Figs. 4 and 6, the gear is secured to the worms'haft 10, previously described, and is inoperative engagement with a change gear 46 which may 'besuitably supported in adjusted position upon a bracket 48. The change gear 46 meshes with the gear 47, 'Figs.'4 and 6, which is itself loosely mounted on apower transmission shaft 49. Extending from the gear"47, Fig. 4, is a hub or sleeve portion 50 carrying at one end a clutch member 51, and splined for sliding movement upon the power transmission shaft 49 the clutch member 51 by means of a shiftlever 53. pivoted at 54 and upon a suitable supporting bracket, the construction being,
such-that when the clutch'members 51 and 5 2 'ar'e engaged, the shaft 49 will transmit I rotative movement to the connected worm 9,
andj when the clutch members are" disengaged the worm 9' at each side "of the loom remains idle. M m
The power transmission shaft 49 may be conveniently driven from a going part of the loom and, as indicated in Fig. 4 said shaft has secured thereto the worm wheel 55 which is engaged with the worm 56 mounted upon a shaft 57 for rota-tive movement therewith during the loom operation.
Each of the worm shafts 10, one at each side of the loom, is provided with a hand wheel 37 as previously described with respect to Figs. 1, 2 and 3, whereby the take-up roll may be turned by hand in a frontward direction to take up the cloth when'the clutch members 51 and 52 are disengaged.
The modified form of the invention as de scribed differs mainly from the mechanism shown and described in Figs. 1, 2 and 3 in that the one way power transmission between the take-up roll and the associated worm wheels 8 is modified as described, and the train of mechanism for operating the worms 9 is modified as hereinbefore noted.
In both forms of the invention, however, the take-up roll 6 is driven at each end thereof through a worm and worm wheel and one Way power transmission device, and in both cases when the actuating mechanism driven from a going part of the loom is made inoperative either by disengaging the pawls 17 and 27, or disconnecting the clutch members 51 and 52, the take-up roll may be turned at either side of the loom to take up the cloth. Similarly, should either one, of the drive con nections become functionally inoperative the take-up roll may be drivenby the other drive mechanism, notwithstanding the worm and worm wheel connection at both ends of the take-up roll.
