I Claims. (01. 139-171) I I In the drawings I have illustrated fragments The invention relates generally to Jacquard box looms or to looms of this general, pattern operated type in which are provided multi-compartment shuttle-boxes and box motion mechanisms '5 for altering the positions of the boxes, and it primarily seeks to provide novel means controlled by the pattern equipment or jacquard head for indicating or selecting the desired effective box position and for actuating the box motion to attain that position.

An example of the type of loom generally referred to is disclosed in the patent to Lookwood No. 573,276, issued December 15, 1896. It has been the custom, in looms of this general type to impose upon the delicately constructed pattern or jacquard head mechanisms the loads incident to manipulation of the shuttle-box position shifting mechanisms, especially when the box-operating mechanism is of the type for shifting the shuttle-box bodily as shown in Figure 12 of the Lockwood patent and distinguished from the rotary type of box, and this imposition of operating load is objectionable.

The invention seeks to avoid the load imposi- 5 tion above referred to and resides in the provision of a prime mover constantly reciprocated from a power operated part of the loom, a plurality of individual, selective movement-transmitting elements constantly connected with the boxoperating mechanism and movable individually or in groups for bringing about the desired shuttle-box positions, and means actuated from the pattern controlled devices or jacquard head for individually or collectively selecting and connecting said elements for movement with the prime mover.

With these and other objects in view which will more fully appear, the nature of the invention will be more clearly understood by following the description, the appended claims, and the several views illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a somewhat diagrammatic side elevation illustrating the invention, a known form of 5 shuttle-box shifting mechanism being illustrated and the frame shown in dotted line phantom.

Figure 2 is an end elevation of the parts shown in Figure 1, parts of the actuator members being broken away.

Figure 3 is a fragmentary detail vertical section taken on the line 3-3 on Figure 1.

Figure 4 is a detail horizontal section taken on the line 4-4 on Figure 1.

Figure 5 is a detail horizontal section taken on 55 the line 5-5 on Figure 1.

of known loom portions in combination with the novel elements comprising the invention. The loom frame is indicated at 5, and 6 designates a constantly rotated shaft forming a part of the loom mechanism.

An eccentric l rotatable with the shaft 6 en-- gages an actuator member secured to the lower end of a rod 8 vertically slidable in a bearing 9 secured to a part of the loom frame as shown in Figures 1 and 3 of the drawings. An actuator bar it is secured to and extends laterally from the rod 8 and is constantly reciprocated in a vertical direction by reason of the constant rotation of the eccentric l. The purpose of the constantly reciprocated actuator bar will become apparent as the description progresses.

Two bell crank members H are pivoted side by side on. the loom frame and one has its respective ends connected in a pull cord or cable l2, and the other in a pull cord or cable l3. The portions of the cords l2, l3 connected with one adjacent set of bell crank arms are passed about individual pulleys l4 and attached to individual actuator levers l5, the pulleys l4 and levers l5 being suitably supported upon bracket members It secured to a portion of the loom frame. A stop member l I may be provided for limiting movement of the levers l5.

t should be understood that the control levers l5 are moved under control of the pattern actuated devices or jacquard head of the loom. In the present illustration the levers are shown as movable upwardly for control purposes, but it is to be understood that they may be placed to move in any direction to accord with the direction of movement of the connected elements of the pattern actuated devices or jacquard head. In the Lockwood disclosure, No. 573,276, corresponding control elements are shown at m and m and for the purpose of comparative illustration the same reference characters are applied to the lever movement effecting elements connected with the levers I5.

In this particular disclosure I have illustrated 'my improved box position indicator or selector operatively connected with a box motion mechanism of known form and adapted for moving the shuttle-box to one or another of four selective positions. This box motion mechanism is disclosed generally in the patent to Lockwood, No. 573,276, issued December 15, 1896, see Figure 12. It is to be understood, however, that my improved mechanismv is adaptable to use in combination with box motion mechanisms other than the particular example of structure selected for the present disclosure.

In the illustrated box motion mechanism there are included differential levers I8 and I9, operated by gear-cranks 20, 2 I, through rods or thrust arms 22, 23. My improved mechanism is designed to select and position the gear-cranks 20, 2|, by movement of the levers 24, 25, upon which they are respectively mounted, and under control of the pattern controlled devices or jacquard head.

To each of the two levers 24, 25, I secure an actuator member. These members are respectively designated 26 and 21 and are selectively controlled, in a manner soon to be described, for individually or collectively connecting the levers 24 and 25 to move with the actuator bar or prime mover l0 so as to leave both levers 24, 25 down, as when both members 26, 21 are disengaged from the prime mover, to lift both levers. 24, 25, as when both' members 26 are engaged with the prime mover, or to lift one lever 24 or 25 while leaving the remaining lever 24 or 25 lowered, as

when one or the other only of the members 26, 21 is engaged with the prime mover. The levers 24, 25 thus position the gear-cranks 20 and 2| so that by their retaining-lever 28 (to which reciprocatory motion is intermittently imparted by the cam surface on the toothed segment 29 through the medium of the connecting-rod 29 they may be put into gear with one or the other of the toothed segments 29 or 30, by which they are operated to move the rod I8 (which is coupled to the shuttle-boxes in the well known manner) through the medium of the rod I8 and the lever I8, their several and varied positions being indicated by dot and dash lines representing the center lines of the levers.

The selective actuator members 26, 21 are provided at their upper ends with hook portions respectively designated 3|, 32 and which are adapted, when suitably positioned, to hook over and attach the members in operative connection with the prime mover, as indicated in Figure 2 of the drawings. I will now proceed to describe the elements by which the members 26 and 21 are shifted, individually or collectively and under pattern or jacquard head control, into or out of the path of the movement of the prime mover.

A plate or table member 33 is secured upon the frame and supports a pair of individual pulleys 34 mounted in a bracket 35. The portions of the cords I2, l3 connected with the remaining adjacent set of bell crank arms are passed about the pulleys 34 and secured to individual actuator member selecting and shifting blocks 36 apertured at 31 to permit passage ofthe actuator members 26, 21 therethrough as shown in Figure 5 of the drawings. It will be obvious that a pull on one or both cords |2, |3 will move a block or the blocks 36 to position one or both hooks 3|, 32 over the prime mover, and springs 38 anchored to the plate 33 serve to return one or both blocks 36 and member or members 26, 21 to the inactive, prime mover disengaged position when one or both cables are allowed by the control devices to move. in the pull relaxing direction.

The pattern or jacquard head devices impart movement to the levers l5 and through intermediate connections hereinbefore described to the blocks 36 for selecting and positioning the hooks 3|, 32 with respect to the prime mover H]. The work of actually controlling the box motion mechanism is done by the power shaft 6 and prime mover I0 and hence the delicate pattern or jacquard head mechanisms are relieved of the loads incident to these operations. Either one or the other or both of the hooks 3|, 32 and actuator members 26, 21 may be connected with or removed from the prime mover I0 for effecting the box motion mechanism adjustments hereinbefore described in detail.
