WARP BEAM FOR LOOMS.
Application filed April 7, 1926. Serial No. 160,409.
This invention relates to improvements in Warp beams 'tor looms and it is the general object ot the invention to. provide such a 1 beam With italse heads which shall be quickly 5 adjustable trom one position to another` and positively held in any adjusted position.
ln certain looms, such for instance as those for Weaving sillr, the Warp beam is provided with friction drums atthe ends thereof and Vio also tal-se heads located intermediate the result and provide means for holding theA 'false heads and the barrel ot the beam in lixed relation by cooperating parts so termed that the yarn Will be permitted to lie props erly on the barrel.
1t is a more detailed object ot my. inven-` tion to provide the body oi the barrel with a Series of diagonal slots to cooperate with a multiple threaded Worm gear` rotatably mounted on some part oit tlietalse head so arranged that it can be tightened with respect to the head to prevent longitudinal motion oic the false heads along the barrel, y The diagonal slots are formed iviththeir bottoms other than concentric with the axis Ot the baiiel so as to resist angular motion ot the false. heads When the Worm gear is tight. When loosened the 'Worin permits tree sliding movement of the false heads along the barrel but prevents angular motion relatively to the barrel.
It is a more detailed object of the invention to dispose the diagonal slots ot' the barrel so that a Warp thread Wrapped on the vbarrel and lying in a plane perpendicular to theV axis thereof vvill be held out ot Contact With the bottom of the slots and will extend from one side thereof across the opening to thev yvill appear as the description proceeds, my invention resides in the combination and arrangement ot parts hereinafter described and set forth in the claims. l Y ln the accompanying drawings wherein I have Shown a convenient embodiment ot my invention, l i i Fig. 1 is a rear elevation of a Warp beam made accordingv to myvpresent invention,
.Fig: 2 is an end elevation taken in the direction ol'v arrow 2, Fig.1,and sliowinglpart rot the loom and the beam as connected With a form of let-oil' frequently used on silk looms,
Fig. 3 is a vertical section on line 3 3 of Fig. 2, omitting the loom` side and showing.
a portion of the barrel in elevation,
Fig. 4 is a perspective view of one of the false head-S looking from the adjacent end of the beam,
Fig. 5 is a detail section Online 5-5 of Fig. 3, and i 1 i Fig. 6 is adetail top plan lookingin the direction of arrow 6, Fig. 3, and showing the disposition of the slots in lthe barrel.
Referring particularly tovFgs. 1 and 2 it Will be seen that I have provided a loom stand indicated at 1()` having a bearing 11 receiving the Vend 12 of a shaft 13 which extends through the beam B. It is tor be understood that there is a bearing 11 at each side of the loom and that the ends 12- are tree to rotate in the bearings except as Yresisted by a Weighted cord 14 anchored as at ltogthe frame ofthe loom and connected to Weights lV at the other end thereof. Said cord passes around a friction drum 16 vvonev of which is located at each end of the beam a Web 19 perforated as at 2OA to pass the y threaded portion 21 of the Shaft 1 3. A nut 22 on each threaded portion bears against the Web 19 and When the nuts at each end are tightened the drums Will be held against the barrel. lRelative rotation of the drums with respect to the barrel is prevented by a lockrGO Y to the aXis of the barrel.
The false heads 30 to Which my invention more particularly relates provide a face 3l which is iinished accurately and is adapt-ed to receive the end threads of the Warp. Tlach false head is provided With a hub '82 Which extends along the barrel 18 a sufficient distance to hold the face 8l perpendicular Said hub 82 is recessed as at 33, see Fig. Ll, and the hub is further provided with an extension Sl into which entends a screw 35. Mounted -for rotation en the screw is a Worm gear 36 having one surface in contact with the head of the screw 35 and having the opposite surface in contact With the bottom of the recess 83 and the extension 84.
As shown more particularly in Figs. l and 6 the barrel 18 is provided with a series et diagonally disposed slots t() the bottoms of Vwhich are perfect-ly flat. Said slots are nettormed as part of a screw thread but have their bottoms tangent to a circle concentric With the axis of the barrel 18 so that the ends of said slots a are farther rem the center of the beam than the central portions ot the bottoms ot said slots. The angle of the slots l0 and the pitch ot the threads on Worm gear 36 are such that the teeth or the Worm Will lit into the slots 40. I have shovvn the slots at one end of the barrel of opposite hand 'from those at the other end, and have shown the vvorm gears of opposite hand also, but l do not wish to be limite to this construction.
Under normal conditions with a given Width of Warp space between the false heads the screvv 35 vvill be tightened so as to prevent relative movement oi the Worm gear 36 with respect to the head. For this reason the head is held against longitudinal motion along the barrel by engagement of the teeth of the Worm gear with the Walls of the slot l() and angular or rotary movement of the heads on the barrel is prevented by the tact that as the Worm tends to turn about the axis of the barrel the teeth thereof Will engage the bottoms of the slots, and as the latter are inclined outwardly from a circle tangent to the lowest part of the slot the Worm gea-r and hence the false head cannot turn about the axis ot the barrel.
llVhen it is desired to change the position ot' either head the bolt 35 corresponding thereto Will be loosened andthe head moved by hand to the proper positicn, the pitch of the teeth on the gear 86 being steep enough to cause the same 'te rotate freely Without offering undue resistance to the sliding movement of the false head. `When the heads 30 are in their adjusted position the screws may be tightened after which said heads will be held in hned relation With Vrespect to the barrel of the beam.
From the foregoing it Will be seen that l have provided a Warp beam having a false head which is movable quickly trom one position to ar ther and is held'against undesirable longitudinal and angular motion with respect to the head by means of a clamping device so arranged as tol have positive Contact With some portion of the barrel at all times but movable to permit ready adjustment of the false head with respect to the beam. lt will also be noted Vthat the angle of the slots is such that a Warp thread lying in a plane perpendicular tc- `the axis ot the barrel i8 will not engage the bottems of the'slots but Will pass from one edge the other thereof and be almost concentric with the anis of the beam. 1While l have shown the slots With ilat bottoms to n'event relative angular motion of the head 'd barrel, yet the spiral teeth and diagonal grooves ci themselves tend to prevent this motion, the diagonal line along which the teeth and grooves coact having tvvo perpendicular components Which act to prevent both longitudinal as Well as angular relative mrnfei'nent between the head and barrel.
Hav ig thus described my invention it 'will be apparent that changes and modifica tions may be made `therein by those skilled in the art Without-departing from the spirit and scope ot tle invention, and l donot Wish to be limited to the details herein disclosed, but what l claim is: Y
