'8 Claims. (01. 139-485) sponding side of the shuttle with a close surface contact fit. This causes uneven wear of the shuttle, binder and box parts and impairs shuttle checking action as the shuttle is being boxed.

If a resilient pivot mounting is provided for the binder, the binder may be displaced radially towards the axis of the pivot and this may cause the shuttle to be boxed out of alignment with the corresponding picker. Moreover, the lateral displacement of the binder permitted by such a resilient pivot mounting may affect adversely the accuracy and sensitivity of the protectionmotion.

One object of the present invention is to provide a new and improved pivot mounting for the binder, which permits the binder to tilt about its longitudinal axis to maintain continuous frictional surface contact between the binder and the shuttle as it is being boxed and which is not yieldable in a radial direction with respect to the axis of the pivot mounting, so that axial alignand from an inspection of "the accompanying v drawings, in which: v

Fig. l is top plan View of a lay and shuttle box assembly shown at the instant the shuttle is being boxed;

Fig. 2 is a transverse section of the lay and shuttle box assembly taken, on lines 2-2 of Fig. 1 and shown with the shuttle coming in at even keel; and

Fig. 3 is a transverse section of the lay and shuttle box assembly similar to that of Fig. 2 but showing the shuttle coming in slightly tipped about its longitudinal axis.

Referring to the drawings, the binder post mounting of the present invention is shown applied to a shuttle box In fastened to the lay I l, as for example, by bolts l2, and comprising a bottom plate I3, a front plate It with a top shuttle guide plate l5 secured thereto, and a rear orback plate l6 spaced from said front plate to receive the 2 conventional shuttle shuttle boxing action.

The shuttle H is propelled by a picker stick IS in any suitable manner. The bottom.box plate [3 has a slot 2!] for the passage of the picker stick L8.

The invention is not limited to' any-particular kind of picking mechanism or general shuttle box construction and that shown is for illustrative purposes .only.

The rear of the shuttle box H] has extending therealong a shuttle binder 25 pivotedat one end H therebetween during 2% to the bottom box plate 13 by a pivot mounting 21'and engaging at its other free end the usual protector finger (not shown) for protector motion control. A spring (not shown) yieldingly 'holds the binder 25 inwardly towards the front box plate M to check the shuttle Ii as it moves into the box In.

.The binder 25 comprises anelongated bar 28 desirably of wood and desirably provided on its inner shuttle contacting side with a lining 3!] of leather or similar flexible cushioning material cemented or otherwise secured thereto. At its pivoted end 26, the binder'25 has a hub 3| forming part of the pivot mounting 21, as will be described.

The binder pivot mounting 27 comprises a rigid.

pivot pin 32, desirably of metal, secured to the bottom box plate l3 by aclamping bolt or stud ably ofmeta1 or other suitable bearing material,

lining the inside of the binder hub 3i and having rotative bearing engagement with the outer periphery of the pivot pin 32. The hub bushing 34 has a hole 35 presenting an inner convexly curved surface 36 in rocking engagement with the pivot pin 32, permitting said bushing 34 not only to rotate about the pivot axis of the binder mounting 21 but to tilt about an axis transverse to said pivot axis, as will be more fully described.

More specifically, the pivot pin 32 is an eccentric bushing designed to permit adjustments in the transverse position of the pivot axis of the binder mounting 21. The eccentric bushing has a cylindrical bearing shank 38 and an annular base flange 4U seated on the bottom box plate l3 and provided With a series of holes or sockets 4| around its periphery to receive a suitable wrench or other turning tool. The binder hub bushing 34 seats on the base flange 40 and engages the Normally, the bolt 33 is tightened to lock the eccentric bushing 32 in adjusted position against rotation. When it is desired to adjust the transverse position of the center axis of the bushing 32, the bolt head 36 is turned to turn the bolt 33 in the splined nut 45 and to loosen thereby the eccentric bushing 32. The bushing 32 can then be turned by inserting a wrench into a socket 41 of its base flange 4B and rotating thereby said bushing into the desired position. When the proper adjustment in the rotative position of the eccentric bushing 32 has been made, the bolt 33 may be turned to lock the parts in adjusted position.

The hole 35 of the hub bushing 34 tapers from opposite ends towards substantially the center to present the smooth rounded internal surface 36 convexly curved lengthwise of said bushing. The surface is curved substantially circularly in the radial planes of the axis of the hub bushing 34, so that said hub bushing constitutes substantially a solid of revolution generated by a segment of a circle rotating about an axis which Y is spaced from said segment, which is substantially parallel to the chord of said segment and which is located on the side of the are of said segment opposite said chord. The radius of the arc is small enough to permit tilting of the binder about its longitudinal axis through an angle sufficient to accommodate any keeling of the shuttle ll normally encountered during shuttle boxing operations, but is large enough so that the spur of the shuttle I! is maintained substantially in alignment with the corresponding icker.

In Fig. 2, the shuttle I! is shown coming into the box It at even keel. In this position, the inner leather lined surface of the binder 25 is in close, continuous, frictional surface contact with the corresponding side; of the shuttle II. In Fig. 3, the shuttle i1 is shown coming into the box It, slightly tilted about its longitudinal axis.

In this position, the binder 25, through the tilting compensating movement of its hub bushing 34 about the pivot bushing 32, has been tilted about its longitudinal axis in position corresponding to the tilted position of the shuttle I! and into close, continuous, frictional surface contact with the side of said shuttle. Even wear of the shuttle contacting parts is thereby assured and effective shuttle checking action is by that means maintained at all times.

While the invention has been described with particular reference to a specific embodiment, it is to be understood that it is not limited theretobut is to be construed broadly and strictly solely by the scope of the appended claims.
