Application and February 1s, 192o. Serial 110359584.

To (455 whom it may concern:

Be it known that i, Josnrii H; TILLING- I 'r, a citizen of the U ni'ted States, residing at an Francisco, in the county of San Francisco and'State of California, have invented new and useful Improvements. in Tool: ta cum-ing- Apparatus, of which the followmg is a specification. 1 his invention relates to improvements in vrus for tacllitatlng the scouring vof wool and like material.

ihe primary ob ect of the mvention is to pro ide apparatus for advancing. wool g scourin baths in a reliahle'and extious manner, and sothat largequaniesof wool maybe scoured ettfectively'and ruiickly much more so than when scoured with the apparatus now in use.

.Knotherand more specific object of the invention is to provide apparatus for mov ing wool through liquid from one end of a 'I said wool out of said liquid and depositing it.

receptacle to the other and then liftingupon a conveyer; the movement of the wool tl'irough the liquid being such as will provide tor a thorough and expeditious scouring thereof.

The invention possesses other advantages 1 and features, somev of which, with the foregoing, will beset forthat length inithe following description wherein I shall outline in full that form of the invention which ll haveselected for illustration in the drawe in s accompanying and forming a part of the present speclficatlon. In said drawmgs,

l have shown one form of the construction of a my invention, but it is to be understood that I do not limit myselfto such "form, since the invention as expressed in theclaims may be embodied in a plurality of forms.

Referring to the drawings:

Figure 1 is a longitudinal fragmentary sectional view through a tank showing the apparatus of my invention in side elevation and partly broken and in section, and illustrating various positions of the apparatus in dotted lines.

Fig. 2 is a top plan view of the apparatus.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1 with certain parts omitted for the sake of clearness of illustration. Fig. 4 is a sectional view taken. on the line 4-4; of Fig. 1, showing a part thereof broken away. p r In carrying out my 1I1Y11l310l1,I mount a reciprocating wool advancing member and that as 'many as desired may be used. 3 The apparatus is'preierably arranged so that the advancing'n ember moves to advance the wool through the liquid, then lifts clear of the wool and moves back to starting position in a plane above the Wool and then lowers into woolengaglng position. Thus the wool is intermittently advanced into a p0sij tion to he lifted out of theliquidby said lifting inemher andin being thus moved is thoroughly'washedwh leadvanc n I The present embed ment ofmy invention as illu'strated'in the accompanying drawings.

comprises a tank or vatl open on its upper side, and containing a'suitablejliquid, not

shown, for washing the wool. one tank, but in practlce I employ several tanks contiguously arranged so that wool is mov d through one and into'the other. Mounted to reciprocate into and out of one end of the tank 1 is awool advancing mom 7 her 2 comprising a frame 3 which is prefer:-

ably rectangular; horizontally supported,

and of slightly less width than'the space between the walls 4: of the tank whereby the the tank or vat and may move freely between sets of spaced fingers or teeth o, the sets preferably being secured to the under side of the frame as at 6 and depending therettrom'at the ends and center of the frame transversely thereof. These fingers extend across the tank and are slightly spaced from the bottom? of the tank when inoperative position. Thetrame j3'is supported just above the level of the liquid which level is indicated by the line'8, whereby I only the fingers are immersed in the liquid.

The frame 3 is suspended from a frame comprisinguprights 9 secured onopposite sides of the tank and a cross piece 10 secured to the uprights. Depending from the cross'piece. is a pair of hangersll having I have shown frame extends substantially entirely across:

the fwalls. Theframe carries aplurality of bearings 12 in their lower ends for horizontal shafts 13 and 14 arranged side'by side and operatively connected by gears 15 fixed to said shafts and meshing with each other. Fixed to each shaft and depending therefrom are pairs of supporting arms 16 provided on their lower ends with rollers 17 which ride in guideways 18 therefor arranged on oppositesides ofthe frame ,3. The arms 16 normallyextend downwardly, diverging from one another and thussiipport the frame 3 in horizontal position. Crossed arms19 are iix'edto the'shafts 13 and 1 1 and extend upwardly therefrom carrying weights 20 thereon above the shafts. These weights are arranged to assist the mechanism in raising the member 2, to the dotted line position shown in Fig. 1. To provide for so raising the mem. er 2 and for lowering it, a rocker arm 21 is fixed to the shaft 13 and'extends substantlally at 7 right angles tothe arms 16 carried by $21K shaft. This rocker arm is pivotally connected as at 22 with a IGCIPIOOEIUIIO' rod 23.

The rod 23 is operatively associated ith the main operating mechanism, which will be later described, and when pulled will rock the arm 21 and rotate the shaft 13 and shaft 14 through the gears 15, causing the arms 16 to lift or raise the member2 as will be later described more fully. The outer end of the rod 23 is provided with a. series of spaced openings 2 1' which provide for ad justing the connection thereof with the arm 21 to regulate the height to which .the member 2 is raised. V i

The member 2 is reciproceted and raised and lowered by operating means comprising frame 25in which. is journaled a shaft 26. Pulleys 27 are fixed to this shaft and support belts'27 driven from a suitable source of power, not shown. The shaft as has pinion 28 thereon which meshes with a. pinion-29 on a shaft 30- also journaled in the frame 25 and which extends across the tank 1. A. preferably rectangular operating frame 31 is pivotally suspended from the shaft 26 by suitablemeans32 which permits the frame 31 to swing backand forth. The

shaft 30 extends through the central point in said frame. 31' and has an eccentrica'll mounted circular disk 33 fixed thereto so as to engage opposite.longitudinal Sides 34 the frame,-said frame being channeled to receive the eccentric33. Thus as the shaft 30' and eccentric 33 rotate, the frame is swung back and forth as indicated in dotted lines in Fig. 1. This frame 31in swinging back tain ends, as at 3?,"50 the frame 3 of the member 2, and at their other ends are p1v-- 1 oted, as at 38, to arms 39 extending downthrough the liquid.

of the drawing. As the frame 31 wardly from and rigidly connected with said frame, whereby when the frame swings, the member 2 will reciprocate.

he wool lifting member comprises a shaft 40 rotatably mounted in a bearing 41 on the lower ends of the arms 39. Spaced tines or lifting fingers 12 are secured to the shaft d0 and eitend outwardly at right angles thereto. The tines or fingers are arranged to extend across the tank, as are the fingers 5, and normally lie in horizontal position, as shown in full lines in Fig. 1. To provide for rotation of the shaft 10 so as to effect a lifting of the wool with the fingers 42, a rocker arm 43 is fixed to the shaft and has an adjustable pivotal connection l lfwith a rezoxiprocating swinging rod 415. This rod 15 is slotted as at 46 at its upper end and slidab'ly and pivotally mounted on the shaft 30 by provision of such slot. A cam is fixed to the shaft 30 and rotates so 21.5110 engage a' roller 48 jon the rod 45. A weighted arm' 19 is fixed to the shaft 10 and has tendency normally to rotate the shaft so as to move the tines42 into down position, this. tendency being normally overcome by the rod and rocker 13, cam 47 and roller 48. The tines 1-2 during the operation of the machine areadapted to extend over a conveyer 50 as shown indotted lines in Fig. 1, which ismounted between the wall a of the tank and leads to another tank notshown.

The means for reciprocating the rod 23 to raise and lower the member 2 comprises a cam 51 fixed to the shaft 30 and bearing upon a roller 52 carried on a slotted guide member 53. The guide member is slidably connected upon the shaft and at one end is connected'as at 54.360 the rod 23. The other end of this member is bent back upon itselfto provide a hook portion The slot in the guide member opens out through this hook end whereby-thesh'aft 30' enters and leaves this open end. The cam" roller 52 is journaled in said hook end and, when the cam rotates thisv roller in engaging the cam the machine is as follandfls'ut ferg'ed. in the liquid therein, so that it will be secured in being moved Assuming that "the apparatus is'in the position shown in full lines in Fig. 1, upon rotating the shaft 26, the shaft 30 is rotated in the direction of the arrow, shown in F 1, by the gears 28 and 29 on the respective shafts. At this time, the cam 51 is in such posit on thatwhen the of the operating frame 31 into the right hand dotted line position shown in Fig. 1 swings to right hand position, as shown in dotted lines the right, the Wool advancing member 2 is moved to the right through the rod 36 cone through the wool and effect a scouring action. After the shaft 30 and eccentric 33 have made one quarter of a revolution, the frame 31 has been swung toits outermost in'Fig. 1, and the member 2 has been lifted so that the fingers 5 are clear of the liquid in the tank, as shown in dotted lines in said figure.

said guide and rod 23 attached thereto will be'moved to the right, such movement rocking the rocker arm 21 and rotating the shaft 13. By rotatingthe shaft 13, the gears 15 on the shafts 13 and 14 provide forrotation of the shaft let also, and the arms 16 are moved away from one another, causing the rollers 17 to move outwardly intheguidee ways 18 and the frame' 3 to belifted. The weights 20 on the arms 19 assist in the lifting of the frame 3 by exerting a tendency to rotate the shafts 13, 1 1, thus it will be seenthat the wool advancing member 2 moves horizontall r inthe tank to advance the wool in front of the fingers 5 and is then position until the end of this backwardmovement of the member 2 is reached, at which time the cam engages the roller 52 so as to push the rod 23 and rock the arm 21 whereby the shafts 13 and 14 will rotate so as to cause the member 2 to descend into the tank into position to engage and advance the wool. At the time that the member 2 is descending into starting position the frame 31 has swung into its extreme left hand position, shown in dotted lines in Fig. 1 and the lifting member 35 has been brought into position to lift up the wool advanced by the member 2 during the previous advancing movement of said member 2. As said frame 31 swings to the left, the cam 17 moves so that the roller 18 which it engages will move freely over the cam so as to permit the rod 45 to move upwardly. This rod has a tendency to move upwardly at all times when the weight 19 is in up position, as shown in Fig. 1 of the drawings, and when the cam 47 permits said rod to move upwardly, the

weight will gravitate and by so doing ro- The cam 51 is so shaped that in rotating against the roller 52 on the guide'53,

tate the shaftf30, so as to bring the fingers 12 fromsubstantially horizontal position into substantially vertical position, such as shown in dotted lines in Fig.1 of the draw ings, and behind the wool advanced by said member 2. e As the member 2 begins to advance horizontally through the liquid, the cam ,47 bears upon the roller d8, so as to depress or push downwardlythe arm. 45 with the result that the shaft 40 is rotated so as to, lift the tines or fingers 41-2, and when so lifting, the fingers will pick up the wool in front thereof. During this lifting up of the fingers, the frame Sibegins to swing back toward the right and this moves thejfingers bodily .in an arc toward the right,;while said;

horizontal position. 'With this operation, the fingers scoop up thewool and. carry it forward; so that when the frame L1 moves to its furthermost right hand position,.said

fingers will ezgtend over the adjacent end of the conveyor 50 anddepositthe. wool lifted thereby on to said conveyor. At the time that these fingers extend over the conveyor. 50, the roller 48 engages'in,anotched sui face57 on said cam 47 and l3l18'IOCi'ff5. is.

permitted to have a quick upward move ment wh ch results in causing the fingers 42 I to "snap downwardly'upon the conveyer and the wool is thus quickly disengaged from the fingers immediately after; this snapping;

down of the fingers 7 on the conveyor. I The, frame 31 is swung back toward the left,

through action of the eccentric33- and the ,fingers aremoved clear of the wool and iconveyer. vIt will thus beseen that the mem;

her 2 has a substantially rectilineal motion,

tank and then lifts clear of the tank perpendicularly, moves back to starting posi-,

tion and then lowers perpendicularly back into the tank. This operation being continuous, the wool is advanced intermittently, and in being thus advanced, the liquid in Wool in such a manner that effective scouring of the wool is supplied. The cam opoperating means is of simple compact form, 4

' utilizing comparatively little power to op erate effectively. The operating means in.

view of its simplicity, and particular arrangement is reliable, positive in operation and capable of operating continuously with out becoming deranged.
