PICKER-MOTION.

Specification of Letters Patent.

Patented Aug. 26,1913.

To all whom, t may concern:

Be it known that we, Jer-IN T. BATTING and LoUis N LAFAYETTE, both of Plymouth, in the county of Plymouth and State of Massachusetts, both citizens of the United States, have invented a new and useful Improvement in Picker-Motions, of which the following is a specification.

Our invention relates to improvements upon that class of picker motion in which the picker is thrown because of its attachment toa moving part in distinction to a picker driven by impact.

Our improvement consists in securing the necessary movement of this picker by means which can be attached to the moving parts of a standard loom and are simpliiied over those now in use and which because of their function can be made of metal.

Our invention will be understood by reference to the drawings in which it is shown in its preferred form.

Figure l is a front elevation of our improved mechanism attached to one end of a loom, and Fig. 2 is a plan of the picker.

Only so much of one end of a loom is shown as will illustrate our invention. Our mechanism is of course duplicated at the other end of the loom in reversed relation.

A is the left hand frame of the loom, A3 being the sword of the lay on which is supported one end of the shuttle race A1 and shuttle box A2, these parts being indicated diagrammatically. On the front of the shuttle box is mounted the picker rod or spindle B on which the picker C is slidably mounted.

Upon the sword A3 is mounted a bracket D to which the picker stick is usually pivoted. Instead we mount thereon the angular brace D1 the upper end of which is attached to the outer end of the shuttle race, thus forming a frame for the support of our improved mechanism. F rom this frame projects inwardly the slotted arm D2 which has a downwardly-projecting hanger d.

E is a reciprocating connecting rod attached at one end to the lower end of the power arm F by a slotted connection, the power arm F being pivotally connected to the arm. D2 by means of the bolt f which passes through the slot therein. rlhe connecting rod E is connected to the source of movement in the usual way, and is given the same movement as when connected to the picker stick and by the same means. These means being well known in the art need not be described. By this means the power arm is given a violent throw to the left (see Fig. l), and the power arm being mounted on the lay, this movement is in a plane parallel with the shuttle box.

The upper end of the power arm is connected by a strap F l and spring c with the picker C, the strap F1 passing over a roller c2 mounted in suitable bearings on the side of the shuttle box under the picker rod. In addition a bunter c3 of raw hide or the like is provided to take the return blow of the power arm, a similar bunter g taking the force of its direct blow.

The picker having been thrown or rather jerked t-o the right (see Fig. l) by the usual movement of the parts operating the connecting rod E, it is returned to its original position by means of the pull back arm G. This arm or lever G is fulcruined in the lower end of the bracket (l.

The picker C lies between two members of a frame H between which it is carried and which slide with it on the rod B. This frame H has a third member 72. which is so shaped with relation to the rod B as to leave an 'opening il between it and the rod B through which opening the upper end of the pull back G projects, the opening being sufficient in size to allow considerable free movement on the part of the pull back arm. The lower end of the pull back arm is attached to a spring G1 of such character as to tend normally to hold the pull back arm in the position shown in Fig. 1. Then therefore the upper end of the power arm has been moved to the left and has jerked the picker to the right the length of the shuttle box and has caused the shuttle to be thrown, the picker pulls the upper end of the pull back level' wit-h it against the force of the spring G1 which immediately on the release of the power arm draws the various parts into their original position.

To avoid any serious breakage to the strap or power arm in ease anything catches, we prefer to attach the strap F1 to the picker by some simple and inexpensive device which can be easily replaced in case of accident. Such a device might be a screw or screw eye which would be sufficiently strong to hold under all ordinary conditions, but which in case the picker does not move smoothly, will yield Aperhaps to the point of breaking. Another means of connecting these parts is shown in the drawings where a spring e connects the strap F1 with a screw 01 or other like connection mounted in the picker C. The spring may yield slightly in overcoming the inertia oi' the picker and when the picker has started will give it an additional impetus. In either case the unusual strain is taken off the strap and power arm and given to the yielding part and by yielding part we mean either the spring or the screw or pin by which the strap and picker are connected.

The slots in the arm I)2 and in the' power arm F allow the parts to be adjusted ac-` cording to the requirements of any particular loom upon which this improvement is mounted, or to allow for the stretching of the strap or any other like evidences of wear.

Ve do not mean to limit our invention to the precise form of parts or to the precise arrangement shown, as the desired result can be secured in other ways.

Vhat we claim as our invention is -1. In a picker motion, a lay, a picker, a power arm, means for supporting said power arm comprising a stat-ionary ulcrum mounted on said lay, a strap one end of which is connected to said picker and the other end to said power arm whereby the movement of said power arm will throw the picker, and a spring-controlled pull back arm loosely connected to said picker to return the picker and power arm to their original position.

2. In a picker motion, a lay, a picker, a power arm mounted on said lay, a roller, a strap connecting one end of said power arm and said picker and passing around said roller, whereby the movement of the strapconnected end of said power arm in one direction will cause the movement of said picker in the opposite direction, and means for returning said picker and said 'power arm to their original positions.

3. In a picker motion, a picker and means for throwing it comprising a power arm, a pulley located substantially in the plane with the line of travel of said picker, a strap passing over said pulley and connected at one end to said picker and at the other end to said power arm, and means for returning said picker, said power arm being mounted in a substantially vertical position, in combination with means for mounting it located under said picker.

4f. In a'loom, a lay, a frame mounted thereon and carrying a slotted arm, a power arm adjustably mounted in said slotted arm, a picker, and connections between said power arm and said picker whereby the throw of said power arm will throw the picker, and means for returning the picker and power arm.

5. In a loom, a lay, a frame mounted thereon, a power arm, means for supporting said power arm comprising a stationary fulcrum mounted on said lay, a picker and connect-ions between said picker and said power arm comprising a strap and a yielding connection between said strap and said picker whereby upon any unusual strain on the parts said connection will give and prevent breaking of the other parts.

6. In a picker motion, a picker, a power arm, connections between said picker and said power arm whereby said power arm may throw the picker, and means for moving said power arm comprising a connecting rod positively and adjustably connected thereto, as described.
