When the set screw 22 is screwed in,.it will be seen that. the rod 16 is forced firmly into t-he'fseat 18f and thus held accurately in position and a lock nut 23 onthe set screw 22 insures the permanent position of the' rod.

It will thus be seen that the picker is very accurately guided bythe rod 16 at its lower end andthe-slot atits upper end so that it can only move longitudinally of the lay with' its shuttle engaging point moving on a right line parallel with the raceway and parallel with the side walls ofthe shuttle i The picker is given this longitudinal j movement by a construction which is so arranged as to haveno tendency to deflect the picker'ffrom this right line movementjand;

consequentlyno tendency to deflect theshuttle'from its right line movement. This result is secured by mounting the picker stick entirely beneath the raceway, by having the 7 to a rocker shoe 25 of afamiliar type which beneath the racewayandextends'in front of is'soshaped that as it rocks on the surface of the rocker support 26, the upper end of the picker stick, where it engages the picker, will move in a horizontal path. The, picker stick is shown as given its swinging movement' in theplane of the lay and parallel with the path of the picker by the usual connection 27 extending to the usual pick mo tion. It willbe notedthat the picker stick 2% swings in aiplane immediately adjacent to and parallel with the picker, as 'shown'in Figs. 2 and 3-. At its'upper end, the picker stick is loosely connected to the picker so that it will not have any tendency to deflect the picker from its right'line movement.

" The connection between the picker stick 7 and picker may, of course, bevaried in form,

but a simple and preferred connectionfor securing. the desired results is illustrated.

A lug 28"'projects laterally from the picker the picker stick. This lug maybe of any suitable material and preferably of the same material as the'picker and is shown as fitted in a slot in the picker and threaded over the rod 16. Theface29 of this lug opposite the picker stick; and cooperatingtherewith is vertical and convex so that, notwithstanding the swinging movement of the picker stick, the picker stick engages this lugin the'same horizontal plane.'

A strap 30 is secured by screws 31' to the web of the picker and extends around its outer end and around the end of the pickerthe picker stick and around the lug 28 and is secured to the inner face-'of the lug screws 32. Thus the upper end of the picker stick is loosely embraced and held in its proper rela tion to the picker and the lug 28..

Any suitable means may be provided for checking themovement of the picker stick. An ordinary type of picker check is shown at 33 secured to the lay and in addition a bufler in the form of a sinuous strap 34 threaded on the guiding'rod '16 at its inner end is illustrated, also a buffer washer at I the outer end of the rod. v 7

It will thusbe seen that all the desired advantages are secured by this invention. The movement of the picker in a right line longitudinally 'of the lay and parallel with the raceway and the shuttle box walls is secured by the construction of, and guiding means for, the picker employed. The location-and movementof the picker stick and its connection to the picker are suchthat there is no tendency to deflect the picker from this right line movement. The side walls of the shuttle box are left intact so far as the picker mechanism is concerned. Opportunity is afforded forfthe use of any desirable picker check and buffer. The construction is of a simple, rugged and efiicient naturepThe movement of the shuttle'when picked from the box is therefore, so far as the picker mechanism is concerned, certaln to be in a right line along the raceway and into the opposite box without deflection from its course. 1 w

Having thus described the invention, what is claimed as new, and desired'to be secured by Letters Patent, is: I

1. A loom comprising a lay having a race- 7 way, a shuttle box on the lay at the end of the raceway, a picker extending above and below the raceway and mounted on'the lay to slide longitudinally thereof with its head moving parallel to the raceway and 'midway of andparallel to the shuttle box walls, and a picker stick located entirely beneath the raceway and swinging in a plane parallel to and immediately adjacent to thepicker and loosely connected at its upper endto the picker to impart longitudinal movement thereto. i

2. A loom comprising a lay having a raceway, a shuttle box on the lay at the end of the raceway, a picker extending above and below the raceway and mounted on the lay to slide longitudinally thereof'with its head lug projecting'laterally from the picker. be-

Yneath the raceway and presenting a vertical convex face, a picker stick located entirely beneath the raceway and swinging in a plane parallel to the picker, meansv for loosely connecting the upper end of the picker stick to opposite'the convex faceof the lug to cause the picker stick acting against I the lug to impart longitudinal movement to Y the picker.v

3. A loom comprising a lay having a raceway, a shuttle box on the lay at the end of the raceway, a picker, extending above and j below the raceway and mounted on the lay to slide longitudinally thereof with its head moving parallel to the raceway and midway of-and parallel'to the shuttle box walls, a picker stick located entirelybeneath the race way and swinging in a planeparallel to the picker and immediately adjacent thereto, a

lug projecting laterally from the picker in front of the upper end of the picker stick,

and a strap extending from the picker I 7 around the'upper end of the picker stick and acting loosely to connect the picker stick to the picker and maintain the picker below the raceway in a plane normalto the igitudinally thereof and guided in its sliding movement to maintain the shuttle engaging 130 point of its head on a line parallel with raceway and mounted on the lay to slide lonv the raceway, and a picker stick located entirely beneath the raceway and swinging in a plane parallel to and immediately adjacent the picker and loosely connected at its upper end to the picker to impart longitudi nal movement thereto.

5. A loom comprising .a lay having a raceway, a shuttle box on thelay at the end of nal movement thereto.-

the raceway, a picker extending above and below the raceway in a plane. normal to the raceway and mounted on thelay to'slide longitudinally thereof and guided in its sliding movement to maintain the shuttle engaging point of its head on a line parallel with the raceway, a picker stick locatedentirelyjbeneath theraceway and swinging in a plane parallel to and immediately adjacent the picker and loosely connected at'its upper .end to the picker," andmeans for bodily q moving the picker stick lengthwise during its swinging movement to cause its point of engagement with the picker to move parallel with the raceway, whereby there is no tendency on the part of the picker stick to I impart anything other than longitudinal movement to the picker.

.6. A'loom comprising a lay havingaaracee.

way, a shuttle box on the lay at the end of the raceway,"a longitudinal slot through the a raceway at the shuttle box end, a rod secured to the lay and extending longitudinally thereof beneath and parallel with the said slot, a picker having a bore at its lowerend v fitting the .rod, the said picker extendingthrough and guided by the said slot whereby its head is accurately guided in its'moveinent parallel with the raceway 'and 'longia tudinally thereof, and a picker stick located i entirely beneath the raceway and swinging in a plane parallel to andimmediately adjacent the picker and loosely connected at its upper end to the picker to impart longitudiv In testimony whereof, I have name to this specification.
