WILLIAM S. WELLS, OF BETHLEHEM, PENNSYLVANIA, ASSIGNOR TO BENJAMIN EAST- WOOLD COMPANY, OCE' PATERSON, NEW JERSEY, A GORBORATION OF NEW JERSEY.
TAKEJJ']? MECHANISM FOR LOOMS.
Application filed April 2,
To (12110710127 it may concern:
Be it known that I, VILLIAM S. WELLS, a citizen of the United States, residing at Bethlehem, in the county of Lehigh and State of Pennsylvania, have invented certain anisms for looms, and it consists in an improved take-up mechanism by which the sheet of woven cloth and warp can be maintained at any desired tension, the clothbeam being allowed to slip relatively to its driver so as to compensate for the continuing increase in diameter of the cloth wound thereon and having a coupling means through which it is disconnectively connected with the driver and which may be operated by the weaver so as to release the beam for rotating it backward, freely, when ever occasion demands.
In the drawings,
Fig. 1 is a rear elevation of the improved mechanism Fig. 2 a side elevation thereof, a part of the loom frame appearing in section;
Fig. 3 is a View showing the shaft of the cloth beam in elevation and the coupling and driver in section;
Fig. 4 is an inside face view of the parts shown in Fig. 3, partly in section and partly broken away;
Fig. 5 is an outside face view, partly broken away;
Fig. 6 is a view similarto Fig. 5, with the clamping wheel and nut removed;
Fig. 7 shows one of the friction-disks; and
Fig. 8 shows a certain key or spline.
In a bracket a; forming part of the supporting structure of a loom is journaled the shaft or shaft portion Z) of a beam 0, it being understood that the beam is fixed on its shaft. The shaft has a pin a? driven through a hole therein so that both ends project, the pin forming a detent. The end of the shaft is reduced and threaded as at a.
A coupling member is formed by a bushing f which is penetrated by the shaft. It has at its inner end an enlarged head which is formed with dia'metric grooves f equally spaced. The other end of the bushing is exteriorly threaded, as at F. The bushing further has a longitudinal exterior groove which may extend from end to end 1923. Serial No. 629,273.
' thereof. The coupling 7 may be interlocked with the beam to rotate therewith by turning a hand-clamping wheel 9, which is screwed onto the threaded portion e of the shaft, so that the pin a? is engaged in one of the grooves F.
It is the driver, being a gear freely revoluble on the bushing; it may form a part of a gear train one of which, 2", is shown in Fig. 1. In the preferred form it has in its web, penetrating the same and projecting from both sides thereof, inserts h of cork or other suitable material that will afford a good friction grip.
On each side of the driver and penetrated by the bushing is a friction disk j, one of which is adapted to abut the enlarged head f of the bushing. Against the other disk bears a triangular plate spring K: which is penetrated by the bushing, its three extremities being bent inward and its central portion being subject to the pressure of a nut Z screwed on the threaded portion f of the bushing. Whereas the driver 7t is adapted to revolve on the bushing the two disks are held against revolving with respect to the bushing by a spline m which is set in the groove 7 of the bushing and has two outward projections m spaced sufficiently to admit the driver between them and engaged innotches j formed in the disks. Thus the driver is capable of slippage rotatively relatively to the beam, such resistance as is opposed thereto being determined by the degree of clamping pressure effected as between f and Z when the latter is screwed up against the spring 72.
When the device is in use the weaver screws up the nut Z to produce that degree of clamping pressure which will maintain the desired degree of tension on the sheet of cloth and warp designated A in Figs. 1 and 2. As the diameter of the windings of cloth increases on the beam there will be a compensating slippage of the driver relatively to the beam, and if necessary the weaver may from time to time further screw up the nut Z to maintain the predetermined tension. Whenever it is necessary for the weaver to release the beam from the driver so that he may rotate it backward, he turns back the wheel 9, which releases the interlock at 0? F.
It will be seen that the construction is quite simple and inexpensive and that the device may be readily applied to any existing loom without material change therein. The two disks, which afford broad friction surfaces on both sides of the driver, are locked to the rotating structure ?)f by a simple expedient consisting of the peculiar spline m, which nevertheless allows the driver to slip rotatively relatively to the disks, the necessary frictional resistance being obtained by nut Z and the shoulder formed on said structure at the inner side of head f coacting to clamp the disks and driver between them.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a loom, the combination of a supportingstructure, a beam ournaled therein, a coupling member for the beam adapted to revolve concentrically thereon, said beam and member having releasable means to interlock them for rotation together, means to drive the beam including a driver concentric with the beam, and means to maintain a slip-friction-grip between the driver and coupling member.
2. In a loom, the combination of a supporting structure, a beam journaled therein, a coupling member for the beam adapted to revolve concentrically thereon and shiftable axially thereof and said beam and member having portions adapted to interlock them on shifting said member in one direction, means to shift said member into and hold it in interlocked engagement with the beam, means to drive the beam including a driver concentric with the beam, and means to maintain a slip-friction-grip between the driver and coupling member.
8. In a loom, the combination of a supporting structure, a beam journaled therein, a coupling bushing for the beam adapted to revolve concentrically thereon and shiftable axially thereof, said bushing having at one end an enlarged head and the beam and head having interlockable portions, means at the other end of the bushing to shift the latter in the direction to interlock said portions, means to drive the beam including a driver concentric with and revoluble on said bushing, and means on the bushing coacting with said head to exert slip-friction-clamping pressure on the driver.
4-. In a loom, the combination of a supporting structure, a rotary structure journaled therein and having a a longitudinal groove lateral of the shoulder, a driver for the rotary structure concentric with the grooved portion thereof, a pair of clamping members penetrated by the grooved portion of said rotary structure and arranged one on each side of the driver, means coactive with said shoulder to cause said members to clamp the driver, and a spline engaged in the groove and contained in said members and driver, the driver being revoluble independently of said spline but the spline having on each side of the driver projections interlocked with said members.
In testimony whereof I afiix my signature.
WILLIAM S. IVELLS.
