SHUTTLE PLACER Filed Dec. 28, 1940 Patented Oct. 14, 1941 UNITED STATES PATENT QFFICE 2,259,048 SHUTTLE-PLACER I Joseph Stuer, Lawrence, Mass.- Application December 28, 1940', Serial No. 372,125

3 Claims.

This invention is a guide for the shuttles in the upper cells of a vertically reciprocating drop box loom to locate each one in the right position where it will be in the right position to receive a bobbin from a battery or amagazine, and where it will not strike the picker as the drop box moves up or down in case the picker rebounds, or gets out of place for any other cause.

To locate the shuttle in the correct position and to line up the shuttles in the upper cells, it is convenient to move any projecting shuttle by pushing on or guiding its metal point. However, if the shuttle is moving with the box against any kind of a guide, even if the guide is metal, the shuttle point cuts a groove in the guide. Such a groove constantly gets deeper with the result that the position of the shuttles will gradually shift horizontally thus causing any bobbin which is being transferred to engage the shuttle in the wrong position and thus produce a jam.

To correct this fault, I provide a movable guide which can be adjusted horizontally to compensate for any wear on the guide by the point of the shuttle.

In the drawing, Fig. 1 is an elevation of a loom, with parts broken away, and with my device in place. Fig. 2 is an elevation of the shuttle box guide with the shuttle guide removed. Fig. 3' is a plan view of my device in place.

Fig. 4 is an elevation of a modification and Fig. 5 is a view similar to Fig. 1 of the same modification.

Fig. 6 is an elevation and Fig. 7 is a plan View, partly in section, of other modifications.

In the drawing, A represents a loom frame which, as shown in Figs. 1, 2, and 3, carries a revoluble magazine or battery C of a well known type. F is a transfer hammer which cooperates with other parts to transfer a bobbin B from the magazine C to the top one of the shuttles S such as II or l2, shown as carried in a drop box D having two cells I and 2.

The lay L, which moves back and forth as is customary, carries the drop box D and a picker P, shown as movable on a rod such as 3 and as having a stop 4 of a well known construction.

E represents a drop box guide member with a side face 5 which serves as a guide for drop box D. Member E is of the usual construction except that its front face 6 is flat and through it pass the Shuttle guide member G is formed with the two supporting arms 31 and 38. The slots 35 and 36 pass through arms 31 and 38 and the shuttle point guide face of member G is straight at the upper part 39 and'curves downand out near the bottom 40 so that as the drop box D moves up, guided by box guide face 5 of member E, the metal tip of any shuttle which protrudes from one of its cells will strike the part 40 of shuttle guide member G and as it continues to move up, the shuttle such as H or I2 is moved back into the correct position. The top of this shuttle guide member G as shown in Figs. 1 and 2, extends up to a point as high as the top of the drop box D ever reaches.

In some types of revoluble magazine looms and especially in hand fed looms, a relatively high drop box guide such as E is preferable. Looms of this kind are in general use where there are drop box shifting devices to so move the drop boxes as to change a working shuttle of one color'to one of another color. In other types of looms such, for instance, as those which have a fixed magazine M shown in Figs. 4 and 5, a drop box guide such as H which is of less height than E is preferable With a tall drop box guide such as E, I preferably use a tall shuttle guide member G but with this last type of loom with a low drop box guide such as H, I use a relatively low shuttle guide K attached to it by one bolt passing through one slot 5| in guide K and a hole 52 in guide H.

In the construction shown in Figs. 1, 2 and 3 where there is a relatively high arm or blade with I two slots, the shuttle guide can be moved horizontally and also to a limited extent its guiding surface can be changed from the vertical.

As shown in Figs. 4 and 5, shuttle guide K has a vertical blade 54 with a shuttle guiding surface 55 which is curved outward at the bottom 56 so as to catch the nose of a shuttle as it moves upward with a drop box. Guide K is carried by a narrow blade or arm 53 which extends at right angles to blade 54. Slot 51 passes through this arm 53. On box guide H is a horizontal guideway 51 in which the arm 53 is slidable. By the means of a bolt 50 and a nut 58, shuttle guide K can be moved horizontally but its guiding face 55 cannot be changed from the vertical or from its original angle whatever that may be.

As shown in Fig. 6 I may use a drop box guide J with a smooth face 42 through which is a hole 63. In this case, the shuttle guide N can have a guiding face 44 which extends down and out at 46 and, as shown, is carried by an integral arm 45 through which is a hole 41 for a bolt 48 carrying a nut 49. In this case, there is no horizontal adjustment but the whole guide N can be shifted with bolt 48 as a pivot.

Another variation is shown in Fig. 7 where the drop box guide is shown as having an arm 60 through which is a horizontal hole 6|. Shuttle guide R is carried by an arm 62 which passes slidably through the hole 6| and itself has a threaded hole 63.

61 is another integral arm extending from drop box guide 0. Through arm 61 is a hole 69 which registers with hole 63. An adjusting member 66 passes through hole 69 and has a screw shank 64 which engages the threads in hole 63. Member 66 held in place by a collar 65 and a turning head 68, so that by turning head 68 guide R can be moved back and forth as shown by the dotted lines to regulate the position of a shuttle such as S.

I claim:

1. The combination in a drop box loom including a frame and battery carried thereby together with a lay which carries a vertically reciprocating drop box with a plurality of shuttle cells, a picker and a drop box guide pierced with an adjusting bolt hole and positioned opposite the outer end of the drop box; of a vertical shuttle guide of L- shape in horizontal cross section, the guide having a horizontal adjusting slot; with an adjust-r ing bolt which passes through the slot in the shuttle guide and through the hole in the drop box guide.

2. The combination in a drop box loom including a frame and battery carriedthereby together with a lay which carries a vertically reciprocating drop box with a plurality of shuttle cells, a picker and a drop box guide positioned opposite the outer end of the drop box; of a vertical shuttle guide; with means to adjust it horizontally on the drop box guide.

3. The combination in a drop box loom including a frame together with a lay which carries a vertically reciprocating drop box with a plurality of shuttle cells, a picker and a drop box guide positioned opposite the outer end of the drop box; of a vertical shuttle guide; with means to adjust it on the drop box guide.
