LOOItI.
Application filed April 18, 1922. Serial No. 554,779.
To all whom it may concern:
Be it known that I, EDWARD BLooM, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Looms, of which the following is a specification.
In order to prevent the formation of socalled shiers in woven cloth, that is, spaces between shots of filling or weft which are at intervals excessive, it has been proposed to arrange the reed to yield backward subject to the returning pressure of a spring. It is not possible by applying a spring in some obvious way to a backwardly yielding reed to obtain the desired end, for in order to have the reed beat up effectively it must not yield too readily, and in the effort to provide suflicient spring force the result in practice has been to produce an excess thereof, so that the reed does not yield readily enough and shiers are produced the same as before.
The object of this invention is to provide an attachment for looms having rearwardly yieldable reeds which will offer spring resistance to the yielding of the reed and will permitready and delicate adjustments of the spring resistance from as low to as high a degree of such resistance as might be required. V
While especially designed for controlling the yieldable reeds of looms it will be under stood that the improved attachment may be utilized in many other analogous applications.
In the drawings,
Fig. l is a front elevation of the upper part of a loom batten structure;
Fig. 2 is a vertical sectional view of what is shown in Fig. 1, the section being in a plane through the reed;
Figs. 3 and 4: are sectional views on the lines 33 and 4% of Fig. 2, Fig. 4 being enlarged; and
Fig. 5 is a vertical view on the line 55 of n the lay-swords a is secured the batten Z) having shuttle boxes 0. The batten is provided with a longitudinal recess Z) at the back which is adapted to receive the frame in which the reed is mounted. (Z is the reed and e the rectangular frame in which it is mounted. In the present case this frame has bolted to it, at the back and at the sides or ends thereof, a pair of brackets f, each of the two brackets having inwardly projecting and opposite trunnions k engaged in the bearings f of the ears 7 on brackets f. The reed frame 6 is thus pivotally supported, its lower portion occupying the recess 6; it may swing forward and back on the trunnions it, its forward limit of movement being determined by contact with an abutment piece 2' arranged inthe recess 5.
The bolt 9 may secure in place, as well as the angle bracket 7b, a substantially U- shaped bracket j whose arms j j are horizontally opposed to each other. The arm 7' has a hole 71 and the arm i a hole which is axially alined with hole 70 but of greater diameter; Z is a stud which for the greater portion of its length is polygonal in crosssection, the remainder thereof forming a reduced threaded extension Z thereof. The stud is fitted to the bracket j by being introduced into its hole 70 the shoulder thereof at 76 abutting the inner face of the arm 7', the extension Z of the stud occupying the hole 70. On the extension is screwed a nut m. The polygonal portion of the stud protrudes from the hole 70 and is thus adapted to receive a wrench for turning the stud in its bearings 70 70 and when it is turned to any desired position it may be there secured by tightening the nut m.
On the polygonal partof the stud is fitted a sleeve 9% which has a polygonal hole 11 which fits the stud, so that when the stud is turned the sleeve turns with it. The sleeve has an exterior flange n at one end, and this is provided with one or more notches n Fitted over and revoluble on the sleeve, which is exteriorly cylindrical in form, are rings 0 which are free to rotate on the sleeve; exterior-1y they are of approximately the same diameter as the flange n of the sleeve, so that the flange and the rings present a substantially continuous bearing surface.
72 is a helical spring which is coiled around the flange and the rings and has one end bent inward, as at p, and engaged in one of the notches n of and thus bearing against the sleeve and has it other end 39 arranged to bear against the back of the bracket 7.
It will be obvious that by manipulating and arranged with i the present the nut m and stud Z the pressure on the movable reed-including structure d, e, f may be varied as desired. Such pressure may be made very considerable or very little, as the nature of the goods being woven requires; moreover, the arrangement permits most minute variations of the pressure to be effected.
The object to be accomplished is to provide a bearing for the coiled or body part of the spring interiorly thereof and reduce to the minimum the friction, incident to its tightening, as between its coils and this bearing. This is effected by providing one or more bearing members, in the present case two such members 0 0, which are revoluble on the axis of the coiled or body part of the spring and are embraced by its coils, they being preferably revoluble indepen dently of each other. The support hereii'iaftermentioned in the claims-is taken as represented in the present example by the batten-including structure a 7), either bracket 7', either stud Z and sleeve 07., the last-named part' Z-m (here actually made in two parts, though revoluble as one) not only affording a journal for the members 0 0 but being in case adjustable revolubly on the above-named axis relatively to the remainder of the support so as to vary the tension of thespring, one end of which. has a bearing thereagainst, incidentally, the member n also affords at 72?, as described, a bearing member for other coils of the spring.
At 0 holes are shown in the rings 0 whereby oil applied to the spring may reach the stud Z and serve as a lubricant.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. The combination of a support, a struc ture to be controlled movable back and forth therein, a spring having a helical'body part and one end portion bearing against the support and the other opposing movement of said member in one direction, and a bearing member embraced by the body part of the spring and freely revoluble in the support on the axis of said body part.
2. The combination of a support, a structure to be controlled movable back and forth therein, a'spring having a pluri-coiled helical body part and one end portion bearing against the support and the other opposing movement of said member in one direction, and bearing members respectively embraced by different coils of said body part and freely revoluble independently of each other in the support on the axis of said body part.
3. The combination of a support, a structure to be controlled movable back and forth therein, a spring having a helical body part and one end portion bearing against the support and the other opposing movement-of said member in one direction, and a bearing member embraced by the body part of the spring-and freely revoluble in the support on; the axis of said body part, the part of the support against which the first-named end portion of the spring bears being revo lubly adjustable relatively to the remainder of the support also on said axis.
4. The combination of a support, a structure to be controlled movable back and forth therein, a spring having a pluri-coiled helical body part and one end portion bearing against the support and the other opposing movement of said member in one direction, and a bearing member embraced by one of the coils of said body part and freely-reyoluble in the support on the axis of said body part, the part of the support against which the first-named end portion of the spring bears being embraced by another coil and revolubly adjustable relatively to the remainder of the support also on said axis.
In testimony whereof I aiiix my signature.
EDTVARD BLOOM.
