UNITED STATES PATENT OFFICE ADJUSTABLE PROTECTION ROD FOR LOOMS sachusetts Application November 16, 1945, Serial No. 629,113
This invention relates to a loom and more particularly to the protection rod which extends along the lay and moves about its axis in response to movement of the back binder when the shuttle enters the box at the end of the lay.
The movement of the protection rod serves to lift the dagger so that the loom will not bang off when the shuttle enters the box. The protection rod is formed of two pieces and it is necessary to adjust the two parts of the protection rod so that both daggers may be similarly positioned with relation to the lips on the frogs which they will engage in case the dagger is not lifted the proper amount. Heretofore, the adjustment of the two parts of the protection rod has been by some sort of coupling with a threaded set screw extending through the coupling against one part of the rod to hold the rod as the same is adjusted. Close adjustment is difficult to obtain by this manner of coupling due to the fact that the end of the screw will tend to enter the same hole or depression in the rod it has previously made and a new position cannot be readily obtained.
One of the objects of this invention is to provide a means whereby close adjustment between the two parts of the protection rod may be had.
Another object of this invention is to provide an arrangement so that the daggers of the protecting mechanism may be closely adjusted one with relation to the other, which is important in running a loom at high speed.
Another object of this invention is to provide an arrangement so that a micrometer adjustment between the two parts of the protection rod may be had for closely positioning the daggers.
With these and other objects in view, the in-,
vention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.
In the accompanying drawings:
Fig. 1 is a fragmental View of the lay of a loom illustrating the protection rod in position there- 011;
Fig. 2 is a sectional View showing the protection rod and a fragmental part of the lay on a somewhat larger scale;
Fig. 3 is a sectional view on substantially line 3-3 of Fig. 2;
Fig. 4 is a perspective view of one of the coupling members of a protection rod; and
Fig. 5 is a perspective view of the other coupling member of the protection rod;
Fig. 6 is a diagrammatic view illustrating two daggers as in different positions with relation to the protection rod;
7 Claims. (Cl. 139-345) Fig. 7 is a fragmental view of the protection rod parts with a modified form of coupling member joining them;
Fig. 8 is a section on substantially line 88 of Fig. '7.
In proceeding with this invention, I have modified the coupling for the two parts of the protection rod. I form the same of two members with a threaded member or screw carried by one and abutting against a part of the other member so that relative positions of the rotation of the members may be adjusted. Thus, there is a positive means of relatively rotatingly positioning the members that their relative adjustment may be had.
With reference to the drawings, [0 designates the lay shown as equipped with a reed II and reed cap l2. Shuttle boxes 13 are provided at the ends of the lay while a picker stick I4 is shown at one end and check strap brackets I5 are shown on the lay in a position to have a strap mounted thereon for control of the picker stick. The frame work of the loom is designated l6 and the lay swords H. The frogs with which the daggers engage are designated generally 18. The daggers are shown at 22 and 23 and the upwardly extending arms 24 on the part 20 and 25 on the part 2| serve to engage the back binder in the shuttle boxes [3 and will be moved by the shuttle entering either of the boxes so as to swing this arm and in turn the protection rod IE to lift the daggers 22 and 23.
The protection rod is designated generally [9 and consists of a part 2| and a part 20. A spring 26 encircles the rod part 20 and has one end 27 secured in a bearing 28 through which the protection rod part 20 extends while the other end of this spring 29 is secured by means of fastening 30 to a collar 3| adjustably held on the protection rod part 20 by means of a set screw 32. By moving this collar rotatably about the rod 20 the spring may be adjusted as to tension and will cause the rod to rotate about its axis to cause the arms 24 and 25 to press against the back binders.
The rod parts 20 and 2| are coupled together by coupling designated generally 35 (Fig. 1) and which consists of a member 36 mounted on the protection rod part 2| and a member 31 mounted on the part 20. These members are each tubular as at 38 so as to receive the end of the rod parts 21] and 2] and are held firmly in engagement on these rod parts by set screws 39. A boss 4!] on the part 36 fits into a recess 4| on the part 31 so as to maintain these two parts in alignment while flanges 42 on part 36 and 43 on part 31 extend outwardly and are in face-to-face engagement. The slots 44 are provided at the flanges 43 while cylindrical openings 45 are provided in the flanges 42 through which bolts 46 of a size to closely fit these openings 45 extend, which bolts also extend through the slots 44'. The slots 44 are sufliciently arcuate so that relative angular move ment about the axis of the rods 20 and 2| may be had by movement of bolt 46 in the slot 44.
I do not depend upon the bolts 46 extending through the openings 44 and 45 to hold the coupling members in adjusted position "but rather provide some positive abutting means in order to accomplish this. In Figs. 1-5 this means consists of an arm 50 on member 36 which provides an abutting face and arm 52 on member 37 which is provided with a threaded opening 53. A threaded member 54 having a head 55 thereon extends through this opening 53 to engage the arm 50 and either forces the arms 50 and 52 away from each other or permit them to be moved toward each other. The member 54' is held in adjusted position by the check nut 56.
In another case instead of providing arms 59 and .52 I tap the flange 43 with a threaded opening 51 (Fig. 8) and position threaded members 58 through each tapped opening, which members each have a head 59 and is held in adjusted position by a check nut 60. Each threaded member 58 will engage the binding screw 46 and serve to move it more or'less through the arcuate slot 44 which is provided in the flange 43. By loosening one member and tightening the other, the two rod parts "may be positively turned one with relation to the other and two surfaces will abut to prevent any return of the setting desired. By this arrangement daggers such as shown in Fig. 6 at 22 and 23, will be adjusted from the out-ofalignposition there shown so that they will be in the same relative position to the lips on the frogs with which they are to engage and. thus when the protection rod is swung by movement of the back'binder the daggers will be lifted the 4 same amount with relation to the frogs with which they are associated.
I claim:
1. A protection rod for a loom comprising two parts, means for coupling said parts together comprising a member attached to one part and a member attached to the other part, an abutment carried by one member and means carried by the other member to engage said abutment and move the same rotatively about the axis of the rod.
A protection rod as set forth in claim 1 wherein said abutment is actuated by threaded means,
- 3. A protection rod as set forth in claim 1 wherein said abutment is actuated by threaded means, the axis of which is in a plane at right angles to the plane of the axis of said rod.
4. A protection rod as set forth in claim 1 wherein said members interfit one with another.
5. A protection rod as set forth in claim 1 wherein said members interfit one with another by male and female coupling means.
6. A protection rod as set forth in claim 1 wherein said members each have flanges and locking means extending between said flanges to bind said members together.
7. A protection rod as set forth in claim 1 wherein said members each have flanges and locking means extending between said flanges to bind said members together and said abutment acts upon said binding means,
