Ta all whom 'it may concern:

Beit known that I, BENJAMIN F. GUINnss, a citizen of the United States residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improveaspeeifcation. v v

My invention relates to looms, and particnlarly' to a shuttle positioning mechanism to position a shuttle aft-er it has entered avshnttle box.

The object of my invention is to provide a shuttle positioning mechanism .of Simple construction and operation, and .which .may becombined with any ordinary loom having a single stationary shuttle box, or'shiftin or change shuttle boxes, at one end.

y; inventionconsists in certain novel featnres'cof construction of my improvements as will be hereinafter fully described.

.In my improvements in shuttle positioningmechanism, I provide a swinging shuttle positioning arm, which has a pivotal motion in a vertical plane, and is yieldingly moved into operative position, so that in case the shuttle positioning arm engages the ments =inLQoms,.of which the following is' upper side of a shuttle which has only partially entered the shuttle box, the operating mechanism of said arm will not bedamaged or broken. And I also-provide mechanism for moving the shuttle positioning arm out of operative position, so that it will be out Iof the path' of the shuttle when the shuttle is picked.

I have only shown in the drawing a de' tached portion of a loom with my shuttle positioning mechanism applied thereto, suiicient'to enable those skilled in the art to understand the construction and operation of the same. Referring to the drawing r-Figure l is a central cross section of detached parts of a loom, with my improvements applied thereto, taken at a point indicated by line l, 1, Fig. 2, looking in the direction of arrow a, same ligure. Fig. k2 is a front sectional view, on line 2, 2, Fig. 1, looking in the direction of arrow b, same figure, and, Fig. 3 shows some of the parts yshown iii Fig. 2, in a diiferent position. f

In the accompanying drawing, 1 is tlie ioom side orend frame, 2 is the breastbeam, Slis the lay, 4 the lay-sword, pivotally mounted at its lower end on a stud 5. 6 is the reed carried on the lay, 7 the hand-rail, Sti-shuttle box, 94a shuttle. 10 is a crank connector to the crank shaft 11, and 12 is the bottom shaft, driven from the crank shaft 11 through gears, not shown, in the usual way. All-of the above mentioned parts may be of the usual and well known construction. .4

I will now describe my improvements.

. At the rear of aingle shuttle box is in this instance secured a stand 8, which has in' this instance, at its upper end, a hub or bearing 8" 'for a rocking pin or shaftl, which is loosely mounted in said bearing. On thefront end of the rocking pin 13 is inthis instance-secured an arm `14, termed theishuttle positioning arm, which has in this instance an offset engaging end 14', which is adapted to engage the inner end of theshuttle, see Fig. 2. The inner end of the rocking pin or shaftk l13 has secured thereon-.the hub 15 of an arm 15; the end of-:the arm 15 carries a pin l16, on which is loosely mounted the hub 17 ,on the upper end4 of a connector on rddn 17. The lower end of the connector or rod 17 carries a pin or. stud 18, which in this instance is' adjustably secured by a nut'19, inv an elongated opening 20 in alever 20.- The lever 20 hasj its. hub 20' pivotallyv mounted on astud 21, see Fig.=r2, which is secured to the loom side. The lever 20 has in this instance a projection or lug 20' thereon, which extends above and is adapted to be engaged byan arm 22 extending out from the hub 22 ofl a lever 22. The lever 22 has its hub 22 loosely mounted, in this instance on the stud 2l secured to the loom side.

A downwardly extending projection 22 on the hub 22, has adjustably connected therewith one .end of a hel-ically coiled contraction sring 23. The other end of said spring 23 s connected with a hooked extension 20t1 on the lever 20. The spring 23 acts to yieldingly hold the extension 22 on the lever 22, in engagement with the lug or pro` jection 20 on the lever 20, and forms in this instance a give-way mechanism for the lever 20, in case said lever is prevented fromv 1.05

ters the shuttle box. The lever 22 has in this instance a roll 24 on its end, which is adapted to be engaged by the periphery of a cam 25 in this instance fast on the bottom or both 'ends of the loom.

shaft 12. A helically coiled contraction spring 26 is attached at onev end to the lever 22, 'and its other end to a pin 27 on the loom sidel, and acts to hold the roll 24 on the lever 22 in engagement with the 'cam 25.

Through the rotation of the shaft 12 and cam 25 thereon, and through the lever 22 and lever 20,l an, up, and down motion is communicated to "tlli'e connector 17, and through arm, lnifnd .shaft 13, a movement is communicated to the arm 14, to yieldingly move said'arm' downwardly into the position shown .in Fig. 2, to engage the end of 'the shuttle 9, after it has entered the shuttle box, to movesaid shuttle outwardly into its proper position, and into engagement with the picker, not shown, so that the loom will not bang oi'i. At the backward movement of the lay, the arm, 14 is moved upward ly, through intermediate connections to the cam 25, so

that the shuttle is free to be thrown or picked from the shuttle box, as shown in Fie. 3.

he advantages of my improvements will I be readily appreciated by those skilled in rthe art. They are of very simple construe,- tion and maybe applied to any ordinary loom wth'onc,orimore shuttle boxes, at one,

l i The operation of my shuttle positioning mechanism is entirely independent of the;

operation of any other parts of the loom,y

and the positioning arm of said mechanism is so operated, that every time a shuttle enters aI shuttle box, the positioning device is yieldingly moved to engage and position ,the shuttle, and the positioningr device Iis then moved out of the way of the shuttle, to allow of its free movement out of the shuttle box. In case the shuttle 9, only artially enters the shuttle box, then the positioning arm 14 in its downward movement will engage the top of the shuttle and be held by the shuttle, and the continued revolution of the operating cam 25 will in this instance cause the extension 22 on the arm 22 to move downwardly against the action of the helically coiled contraction spring 23, leaving the lever 20 and intermediate connections to the positioning arm 14 stationary. It will be understood that the details of construction of my improvements may be varied if desired. For instance' the roll 24, instead of traveling on the periphery of the cani 25, may travel in al cam groove in one side ot said cam, the give-way mechanism, intermediate the levers 20 and 22, allowing of the positioning arm 14 engaging the top of the shuttle, and preventing it from moving, without interferring with the operation of thc cam 25 on the roll 24 on the lever 22.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is: V

In a loom, a shuttle positioning device, located on the lay at onel end thereof, at the inner end of a shuttle box, and comprising an arm having a swivel or pivoted movement in a vertical plane, and means for moving sai arm to engage the inner end of the shuttle, to position the same, said means comprising a rotary driven cam, a cam lever made in tivo parts, a spring for yieldingly holding said parts in positiomand intermediate connections from said cam lever to said arm'.
