PICKING-MOTION.

Specification of Letters Patent. Patented Dec, 14, 1909. Application ledJuly 24, 1908. Serial No. 445,154.

' To all whom it may concern.' f.

l suitable for loomsfor weaving all kinds of ed parts for operatin fabrics.

The principal objects of the invention are to provide a construction which can be apl plied tov all kinds o f looms and which is so constructed that it willbe greatly simplified, and the expense of manufacturing correspondingly decreased; also to provide a construction in which the repairs will be so materially lessened that a loom xer can keep several additional looms in repair; which will be capable of voperating ata higher speed than has heretofore been obtained, and -in-which the shuttle driver will push the shuttle out ofthe box in a rectilinear manner. l Some of the above named objects are secured largely in providing a construction in which substantially no leather-0r wood is used, the picker-strap, raw-hidepicker, picker-stick, sweep-stick, sweep-strap,pow`er strap, and heel-strap, as these part-s are now known in looms, being entirely done away with', and no straps being required except' the harness lstrapand driving strap. In the place of these features, parts are employed which do not wear out and breakas rapidly as the leather and wooden parts.

The invention alsoinvolves 'an improved construction in which the picker-roll is mounted directly on the main shaft so as to simplify the construction of the connect.-

the sweep arm. Another feature-o the invention consists in the provision of means whereby-if the shuttle, driver is caught in the box either.'`

' vAnot er feature'O th'inverition. consists.

forgiving the above mentioned rect inear position.

ing each rotation of the main .shaft.

motion which, like the rest of the mechanism,'can be attached to any form of lever,

and is of universal application, and an important feature is the provision of means whereby the wear on the picker due to the rubbing action thereof will be substantially eliminated. A

The ,invention also embodies other improvements in the details of the picker and shuttle driving mechanism as will appear hereinafter.

Reference is to be had to the accompanying drawings which illustrate one form of 'the.invent1on, and in which,

Figurel is a front elevation of a prac-` ticable form of the picking mechanism with the other parts of the loom omitted; Fig. 2 is a fragmentary end view showing the operation vof the picker roll; Fig. 3 1s an elevation of the picking shaft and connected parts looking at it from the inside of the loom; Fig. 4 is an end view of a portion of the sweep arm showing the shaft in sectionyFig. `5 is a plan ofthe shuttle box guide and picker; Fig. 6 is a sectional v1ew -of one of theself-oiling guides; and, Fig. 7

is a front view ,with the parts in another .For the purpose of l accomplishing the above mentioned results and` others which will .appear hereinafter, the invention is shown ina simple form in which it can be applied .to looms o f'substantially all types, whether for weaving cotton, woolen or other fabrics, and which involves a frame .10 which mayv This frame su ports the main shaft 11 on which is direcfly mounted a picker roll extension 12 carrying the picker-roll 13 heldl in place by a fiat spring 130 endaglng a sclot inthe end of the stud 131. This picker roll is designed 'to come in contact with the -upr perf curved cam surface 14 of a lever 15 so as to depress the outer end of said lever durlever-15 is provided with va notch 16v in the be l:of ordinary construction.

The

end: thereof for engaging a-roll 17 on a and 18 are lever 18.` Both the' levers shown as pivoted on axes .parallel .to the axis of the main shaft.' Through aconnect;

ing -rod 19v the lever 18" operates anarm 20 on thepicking shaft 21 so as lto -oscillate said Vv shaft once "during each complete rotation of the main shaft. The picking shaft 1s mounted lin bearings on brackets 22 fixed to the inside of the frame and/extends along the inside thereof transverse to the axes of the main shaft and levers. It will-be lseen that the operation of the picking shaft 21 is positive and that it must oseillate every time the main shaft rotates. Consequently, if any` thing should occur to stop the picker-lever,

something might break. In order to avoid this the picker shaft is provided with a pair of brackets 25 .in which slide one or more rods 26 having collars 27 t thereon, and springs 28 'for forcing them in one direction. These rods are provided with beveled ends 29 fitting correspondingly shapeddepressions 30 in the hub of the sweep arm 31 which is loosely mounted on a collar 32 on the picking shaft. From this construction it will beseen that,the springs 28 being of lever.

sufficient rigidity, the motion of the picking shaft will be transmitted to the sweep arm under all ordinary conditions, but ,in

case of extraordinary resistance, the ends of the rods 26 vwill be pushed out of -the depressions 30 and rthe shaft 21 can then oscillate without breaking. the parts which are connected with it.

l 11e picking sweep arm 31'is connected by means of a flexible leather strap 33 with a sweep rod 34, which is provided with a Slot 35 for receiving a. pin 36 whlch can be mounted in any one of a. series of perforations 37 in the sweep `-check lever 38. A vroll 39 is mounted on-the sweep rod to bear on the sweep check lever to reduceI friction. The sweep check lever is pivotally mounted lon a bracket 4() which is fixed to the rock 'For this purpose it is provided with. a longitudinal Slot in which is located a'block 71, through which passes a. stud 72 on the bracket 4U. Fixed to the bracket is a link 73 which is connected 'with a pin 74 to which are pivoted links and 76. The link 475 is connected with'the stud l72 and the link 76 with the lower end of the picker Consequently the operation of 'the roll l42` on the lever, 43 will cause the latter to fallfand rise at the bottom tocompensate for the opposite motion at the top. This keeps the top vvin fixed relationto the picker and prevents rubbing.'

The bracket 40 has a brace 44, which supe,

details of construction shown ports a box guide 45, not shown completely herein,as any ordinary formof box guide can be employed. To the brace 44 is con'- nected one end of a spring 46,'the other endl of which is connected with a lever 47 pivoted 7'0 on the axis ion which the picker lever is pivoted, and vhavin a roll 48 `for engaging the latter to normal y force it back, and also to swing' the sweep check lever and picking sweep arm in opposition to the action of.` 75 the picker roll. It is this spr-ing which turns the picking shaft after it has been oscillated by the picking roll. The picker lever extends upwardly into the picker 50, which is mounted to slide on one or more '8 guide rods 51. These are preferably made hollow as indicated in Fig'. 6, and have openings 52 therein, and a slot 53 in the top communicating with said'openings. Oil cups 54 are mounted on thc box guide 'communieating with the interior of these guide rods, so that the rods and their grooves are constantly sel'feluln'ieated. l

Tofrelieve the frame of the jar due to the outward stroke of the picker lever a brake is provided, comprsing alever S0 in position to be engaged by vthe picker, 'and normally pressed up by a spring 8.1. rI`his lever is shown as mounted on the brackets 82 which carry the rods 51. Q 95' The pickerl is provided with a cylindrical metallic shell 55 projecting from it,`and having a plug 56 thereinI for receiving the end of thc shuttle. Behind this shell and fixed on the shuttle check 58 is a bunter 55) for 100 receiving the shell as it comes back. The shuttle check is mounted on a rod-60 and is provided with ,a spring 61 for an obvious purpose. I It will be seen that the embodiment of the 105 invention which has been described is of such a nature as to show that this invention is applicableto all styles of looms, and that it embodies features which render it more `durable than anything heretoforeV known in 11d the art 'for this purpose, and-alsothatthe I other advantages which have been referred to herein can be obtained m a simple'and convenient. manner. j

vWhile I have illustrated and described 11:1. one embodiment, of the`invention, II am aware. that many modifications may be made therein by any'person skilled in the art, and that it maybe applied -in many other ways without 'departing from the sco e ofthe in- 120 vention as expressed in the claims.
