IOO

33 is a developed yiew of the partsshown in a s stated, the inventionfembodies two endless rows of picker lingers or stems travelingin a substantially oblo `ath, the machine being adapted `to strzltld e the roll of cotton. e

The mechanism is snpported upon a suit able frame .or runningear embod in- -side top rails 1 and outslde top rails 2, these rails in practice beingtpreferably made of IIO the I-beam form, as such construction is Simple and enables me to attach the supl porting-brackets thereto in a most convenient manner. The rails 1 1 and 2 2 are con- 5 nected near their forward ends by the crosspiece 3, connected by braces 4 with the fifth- Wheel 5 of the front aXle, the cross-braces 6 and 7 connecting the inside rails at the rear end and adjacent to the rear end of the frame 1o or running-gear, the cross-bars 7 forming a support for the seat 8. As the endless series ofpicker iingers 'or stems and carriers therefor and the driving mechanism are identical on each side of the machine, the descri tion I5 of' one will apply alike to both. The ame or running-gear is supported at the rear end by brackets 9, which at their lower ends carry bearings 10 to receive the'projecting ends ofthe rear axle 11, on which the drivez o wheels 12t are mounted.- These axles have mounted thereon outside of the drive-wheels the beveled .driving-gears .14, which engage with the beveled pinions 15, carried on the s hait 16' of the universall joint 17, said joint z 5 connectingthe shaft 16 withthe drivingshaft 18.

@ne of the braces 9 carries a suitable bearing 19, forming a' journal to support the shaft 1'6, so that the latter-will be capable; of

3o having a slight movement whereby it will accomodate itself' to the 'diferent-v adjustments of the casings. The shaft 16 is provided with a slotl 20, and the universal joint embodies a telescoping sleeve 21', (see Fig. 5,) whereby the length of' the rod 16 may shorten or lengthen, according to the different adjustments of .the means for ele- V vatingandlowering-A the carriersv and theirl picker fingers or stems. Each side of the 4o machine embodies a lower plate or table 22,

f supported by the brackets 23, which have a tcp plate 24 supported in the grooves in the inner faces of" the rails 1 and: 2.- These brackets 234 receive the standards 25 which are provided with athreaded' verticall opening 26 to" receive the threaded screw 27, which at its upper end hasa bearing- 28 in the top plate 24 of the brackets. The screws 27' (there being one at the front and one at 5o the rear side of the machine) each carry a sprocket-Wheel 29v near their upper endI to be engaged by the Worm 30, carried by the adjusting-shaft 3'1. This adjusting-shaft carries a like wormnear its rear en to engage with the sprocket-wheel' of' the rear elevating-screw, and the shaftalso carriesa beveled pinion 32 to mesh with abeveled pinion 33, carried on the end of the shaft 34,

, ournal'ed in the inside rails 1, this shaft 34 6o iiavi'ng a like beveled pinion33 onits opposite end to engage with the beveled pinion of the elevat' -sh-at on the opposite side-of the machine. hus the two s 'afts 31:. are oper- 'ated simultaneously, and vthey are actuated by means ofthe vertical shaft 35, extending of' beveled pinions up from the base of the machine alongside of one of the horizontal shafts 31, provided with -the gear 36, to mesh with a worm 30a, carried by the shaft 31, adjacent to the shaft 35, said shaft 35 having asuitable operatinglhandle orcrank 37. The lower plate or base 22 is constructed at the ends with necks 38, having grooves 39 to receive the lower ends of the brackets 23, the standards 25 resting upon 4these necks and the screw-'threaded aperture 26 in said standards registering with the threadedaperture 40 in the necks A casing is of course provided for the mechanism, the same being morev clearly shown in Fig. 29. As stated, each side of the machine embodies a series ot picker iingers or stems mounted in carriers connected toether and traveling in a substantially obong path. These travelers operate on tracks, one of which is shown in detail in Fig. 2 and to which reference will now be specically had. These tracks embody in their construction aeentral ost 42 and the corner-posts 413, 44, 45, an "46, the central post being' connected to the hub of a spider or brace 47 at its lower end, the respective arms or bracketsof' which connect with the va.

rious corner-posts, and the upp r endl of the central post 42 having the hu the spider 48 connected thereto, the various brackets or arms of which are attached tothe UH er ends of the corner-posts, these osts a -eing of equal length and being firm y secured to the base or bottom pla-te 22', as shown in 30. The lower track 49 consists of two endless bars or strips ofmetal passing around' the corner-posts and' s aced cient away therefrom in order to give s clearance between the tracks andi the posts,

ingthe track being connected to the posts by pins or studs 50, as shown inl said Fig. 3. The upper track, whilev it is ang endless one, is not constructed oi" continuousstri' s or'bars, as is the case 4with the lower trac but has. eifsets at diiierent points in order toperform particular functions, as wili' be hereinafter described. This u per track embodies the side rails 5-1 52 an the curv'ed end' rails 53 54. The ends of' the curved orwa-rd end v rail- 54 terminate abovetheends of the. side rails 51 52', while the ends o` the curved rear end' rail 53'terminate below the oppositeend's of the side-rails 51 52. The carrlers or carrier-irames travel' aro each oi these carrier-frames are castin two sections or halves 55. (See Fig. 1r.) The twosections or halvesl of each carrier-ame are securely lbolted' points.'

v The carriers have-a vertical shaft 56 extending therethrough, which carries a series 57, one pinion foreach nr orstem 58, carried by the carpicker.

veled7 pinions 57 meshing with rien, the

or center of d these tracks, and

together at suitablea the beveled 'pinions 59, carried on the inner ends of the picker fingers or stems. Thesey picker fingers4 or stems are preferably of an' especial 'I construction,

as shown in detail in p Figs. 24, 24, being provided with undercut longitudinal grooves andv curved screwlike teeth 58', whereby they will more eiiectually en age'the cotton during the rotation and hold the samenntil removed therefrom'by the cleaning mechanism. The shaft 56 is driven at the upper end through the medium leg of theirpath or travel.

'ricdon the spindle or shaft of the vpinion 60, mounted on the upper end of said shaft and engaging the' gear 61, which rotates within the box or housing 62 at the upper end of the carrier or frame and is car- 63, having a drive-gear. 64 mounted on its upper end. On

the u per face of this drive-gear 64 is a rib I65, W ch is adapted to engage with rail or plate 66 (see Fig. 10')l during the time that the' carriers are travelingalong the outside Each carrier is provided at its upper^ end between the boi; or ousing 62 and the drive-gear 64 with a screw 67, which engages the up er drivechain, and at their lower ends eac carrier is provided with a screw 68, which engages in the links of the lower driveechain.

i In Fi s. 14 to 21,*inclusive, I have shown in detail t e lower driving-chain, and inv this connection I" would state that the up er drive-chain is identical in construction withl `the lower drive-chain, with the exceptionthat the small rollers employed inthe lower drivechain for traveling on the base or rbed 22 are dispensed with in the up er chain, and also the carrier-actuating mech 'the lower drive-chain, and en aging with theV lower track, is dispensed wit in the upper driving-chain. 'Fi 14 drive-chain with al eXce shows thelower pt one of the shieldsremoved from the chain 1n order to illustratethe construction of the-latter. This chain embodies the alternate links 69and 70.. The

links 69 are rovided withscrew-apert-ures 71 to receive tige screws 67 Aat the upper end. of the carriers or screws 68 at the lower end of the carriers, as the case maybe. Thel links 69 and 70 are ivotally'connected, and in the casing of the 'Il ower chain each of the links carry rollers 72, adapted to travel'upon the -bed or base 22. -Each of the links of the.

lower chain `carries an angle-plate 73,. in which is 'ournaledthe crank-shaped shaft 74, having t e roller mounted on one end for engagement with the rails of the lower track,

- operating between the same,(see yFig.y 3 at its other endv this shaft 74 carries a toothed and segment 76 to engage. with the segment 77, carried'on the u per face of the screw 68 of each carrier.

The shieldplates, it is to be noted, are provided with 'openings registering with the openin s in the links, which openings vre- 68 on the lower end of the'carrier-irames. The carrier-frames are each provided with

cross-arms

82, 83,'and 84, each of which is rovided at its outer ends with rollers 85, the rollers on the arms 82 engaging-the curved end tracks 53 54 during 'the travel of the carriers, the rollers on the guid-arms 83 engaging the ,track 52 during the travel of the carriers and the rollers on guide-arm 84l engaging the track 51 dur'- ing the travel of the carriers. The shafts a, upon which the sprocket-wheels 81 are mounted, carry at their up er ends sprocketwheels or gears 86 87, whic are engaged, respectively, by right and left hand worms 88 ing-shafts' 18. The'operating-shafts 18 are connected together by the cross-shaft 90, 91 at its ends to mesh gears'92, carried bythe said shaft 18. The picker fingers -or stems in their travel as they approach the iront of the machine are guided into engagement with with t e beveled l .the slotted guard 93 by guides 94, having "fiiat faces 95, formed by turning over the material of which the guides Vare formed, so as to insure a guiding-surface for the picker stems or ngers.

Thel ower track, in order to impart the desired movement to ,the carrier-frames, is constructed from point A to point B,which latter point is rto the `center of the rear track, with an abru t descent, and from point B to point C the tracks extend substanti-ally on a horizontal plane. From point C to point D the tracks extend at a slight inclination downwardly and from point D to point E have an abrupt ascent and then descend abruptly from point A E to point F, making point E the high point ofthe track, which is at the forward end of the machine, andfrom point F to point Athis lower track extends on a sli ht ascent. Itis to be noted that the lower trac together with the mechanism which connects with the lower end of the carriers, is intended ordinarily to perform the operating of -the carrierframes and that the upperftracks, together with the guide-arms 82 83 84,' are intended only as a supplemental operating means to actuate the carriers in event of the operating mechanism atthe lower end of the carriers `becoming inoperative for any reason. As

the outside 4rails of the track incline with a slight descent from C to D, the outside upper rail 51 willbe arranged ona correspondin .descent from point C rail l541will incline upwardly from point DA to point E and then'. downwardly to point F the oint F to oint A', and the raill 53 inclining ownward y from point A to point C. Now as the carriers travel around the outside of the endless course the rib .65, sliding against the outer edge of the plate .66, and the drivin -pinion '64 being out of engagement with `t e lrack 129, lthe said carriers are traveling at a slight descent, and as they reach the point D, Fig.

10, the carrlers begin to vascend and continue to ascend until pointE is reached. At this ytime the drive-pinion 64 comes into engagement with the teeth of the rack 129, and the picker stems or fingers 58 are sv ung around to position shown in Fig. 10 and travel lon an incline, at this time during their passage from point E to point F, 'at which time they have :assumed the osition transverse to the moving path of t e I'r.\.achi11e. l From point F to point A the carriers travel on a slight ascent until they reach point A, at which time they enter the Scrapers 96, and from whichpoini the carriers abruptly descend until poi-nt 'B ie reached ,from which po'int they travel around substantially on a plane until point 4C is reached, where they again beginv to slightly descend until they aain reach point D.

By reference to ig. 10 .it 1s to be notecl toD, and the forwa'r a picker stems or that the picker-fingers are turned during their passage through the Scrapers 96 so that 4the entire length of the fingers is .drawn through these Scrapers, and by the time the gers arrive at the offsets or shoulders 97 of the Scrapers the cotton upon the fingers has been drawn to thesmaller or tapered ends thereof.- The fan-blades or vanes .98 are made of a length sufficient to engage with the shoulders 'vor offsets 97 requiring these fanblades or vanes to bend somewhat in order that they may spring past the offsets or shoulders of the Scrapers. The fan-tail ends of the blades strike the cotton now drawn to the ends of thenfingers and throws the same into engagement with the carded belt, which carries it upwardly, vand the fan or brush 115 removes the cotton from the belt and discharges the same through the spout in the sack or other receptacle provided therefor. As the picker stems ror fingers leave the scrapers 96 the same engage with .the carded cleaner 103 and are drawn through the edge thereof, effectually removing any particles of cotton that may have remained on the picker stems or fingers during their passage through the scrapers.

The fingers of the respective carriers von each side of the machine overlap a greater` distance machine,
