Be it known that I, Bum*` A, PETERSON, a Citizen of the United States, residing at Rockford, in the County ofl-innebego'and State of Illinois, huve invented'oert-am new :unl useful In'iprovenients in Spinning'` .Frame Dolier's, of which the following is a specification.

This invention'relates to doiiing mahines upon the spinning frames by means of roll-y ers on the doiler runnin upon a. rail at tached to the spinning rame adjacent to the spindle rail, and by means Oia, roller' on the (lofi-'er running upon rail usually found in spinning .frames below thespindle ruil. The ypo-.sitioi'of the4 first-mentioned rolli-nbeziring util with' reference to Said lower rail"occasionally varies in dijerent spinning frames, end one ofthe objctsof this invention is to provide means whereby The position of the lower roller on thevdoffer may he adjusted 'to eorrespondwith the p0- sition of tile 'lower ruil on the spinning,

AIn the accompanying drnwngs, igurel` is n, fragment/affront elevation of thelowerpart or" aV doffer embodying .the vfeatures of my invention.

The frame of the dofer may he of any 5 suitable construction. As herein shown, the frame consists of an upper section which carries the operating mechanisms not here in illustrated), a lower section which carries the receptacle for dol'ed hobbins and an in: 60 i terlnedinte section The upper ,tion oomprises two tubular columns l "rigidly united at their lower ends by n breeder. Fixed to the lower side o the bracket 2 is e bracket 3. The upper section is supl'iorted 'upon the 65 spinning frame by ineens comprising e suitable number of grooved rollers fl mounted upon :i har -5 iXerl to the brsielret 2, said rollers running upon a channel rail E secured/to the spinning freine adjaeentto the 70 spindle rail. The Channel rail may be attached to the spinning frame in :my preerred Way.v Herein I have indicated said' 'rail as fixed to n number of clips F' (only one being shown in the drawings), said clips 75 being sprung over the spindle rail C1. The distance between the center lineof the row of spindles and tlie front edge of the "rail C1 varies in different spinning frames. When lthis distance 1s less than the usuelorJ se standard distance, a shim G of pro )er thicknessfis placed between the. front edge of the mil C1 and the part of the clip F which en- Igziges the'ohannel rail E.

v6 lare scavenger rollers to keep the grooves 85` of the. rollers 4 from clogging with lint.

Upon the brac-liet 3 is mounted roller 7 in position to bee-r against the edge ofthe rail C2, and thus support the clofer in a-verv tic'al position. To compensate for variations 90 inthe relation between the ifnilsflij and C2 in different spinning 'frames I provide means for adjusting "the rolle'? so that the 'do'fer may he properlysupperted in vertical position. The'rnears `serein shown for 95 this purpose is as follows: The bracket-portion `8 has e horizontally elongated opening 9 therein, through which' entends n boltlO. Suid bolt also passes through an engularff bracket l1 'that "contacts I the lower Vside, of 10e thebrnoket portion 8.. A. flange if?. onthe bolt lies within .the lrslliet ll. A0n jthe'- lower end of' the v`belt .l0 is nut 13h91 tween which 31nd the enge. 12 ere cli.. *nd s the bracket' Il, a sleeve or 'bushing .on ftllell holtnndn weslier The relier T. is f gnsl :.51 .abhmounteg on the bushing-fifi between ,the'brneketll and theffwssher "i5, i011 upper washer 17`which Ahold the bracket 11 and roller 7 against vertical displacement but 'permit them to slide horizontally with relation to the bracket-portion 8. A compression spring 18 tends to move the bracket 11 and the roller 7 forwardly. A bolt 19 has a screw-thread engagement with the bracket 3 and is locked in adjlisted position. by means of a mit 20. To the forward endv of the bolt 19 is pivoted a cani 21 having fiat faces 22 23 and a handle 24. Said faces lie at dilferent distances. from the axis of the '25 provides for a considerable ran/ge of.'

variation in the distance between the vert'if# cal planes of the iront edges of the rails C2' the roller i being moved from gne to another by turningthe carnj'2il.4

and E, position The amount of movement imparted to" the roller 7 through the medium of the cam 21 may oe regulated by causing the stop screw 25 to project more or less from the forward side of. the bracket 1l.

The lintermediate section ,of the dolfer 'trame comprises, in this inst-ance, two posts 2G adapted to fit slidably within the tubular columns 1, the lower ends of said posts being rigidlyxieonniected by a bracket 27. Said bradiret has a pivotalponnection with a tion' arranged toru'n upon the floor. .The laitier section may be of any suitable convstruction, that herein shown comprising a top bracket 28 and a'fraine 25) adapted to contain and support a box l(not shown) to reieive the full. bobbins. The frame 29 is provided with suitable rollers 3C and 3l. lThe intermediate and lower sections are con.- /iirrtetl' yto swing` upon a horizontalaxis cx- 'tendinar f rom front to rear in the vertical nwdian plane of the dofi'cr, by means of two pivot bolts 32 passing through perfomtcd portionsA of the brackets 27 and 28. Any other preferred form of pivotal connection may be employed.

Referring to Fig. 1, and assuming the doll'cr to bc traveling along the front ofthe spinning; frame in the direction indicated by the arrow n: Should the wheels il() rise in passing over an obstruction upon the floor,

' tin` box-supporting section 2S 2) will tilt upon thc axis 32 and the intermediate scclion if 2T will risc, no stress tendingr to tilt lhe nuzrhanismafarrying scclion 1 2 being placed upon the latter.

lfm' rmivcnicncc in moving the doll/.ir into and ont oi' operative relation to the spinning frame, means may lic provided for end of the bolt 10 is a nut 16 and a inovingthe upper or mechanism-carrying section with relation to the lower section 26 27 28 2f). Herein I have shown a rock shaft 33 mounted in bearings on the bracket 2, one end of said shaft being,` provided with a handV lever 34 and the other end with a crank arm 35. Links 36 connect the lever land crank arm with the bracket 28, the links 3G being loosely pivoted to the bracket 28 to prevent binding in case of pivotal movement on the axis 32. The upper section may, if desired, be locked in its lower position by means of a detent 37 ont-he hand lever arranged to enter a notch 38 in a sector 39 fixed to the bracket 2. To prevent the upper section of the dolfer from tilting, on the axis 32 when they doffer is off the spinningr frame, may provide means such as two brackets or rests 40 attached to the bracket 28 in position to support the bracket 2 when the upper part of the doffcr is in its lowest position, as in Fig. 1. When desired, the upper section may be locked in its most elevated position by depressing the lever 34.

until the detent 37 snaps into the notch 4l in the sector 39. f.

The means for actuating and-propelling the doiler may be of any suitable character. Herein I have shown a power-transmitting shaft 42 bearing at its lower end a pinion 43 that meshes with a spur gear wheel 44 {ixed to a toothed wheel 45, the latter being adapted to mesh with the spindle-.bases l) and thus propel the doiler along the spinningr trame. When the doffcris to be placed in operative relation to a spinning frame, the lever 34 is depressed until the rollers 4 are above thc horizontal.Y plane of the rail E,

thfezleierbcingf'hcld'in such position whileI vthe dofl'cr is "pushed against the spinning frame. The upper section .ofthe doli'cr is then permitted to descend until Vthe rollers 4 rest upon the rail E.
