' .Letto/"s Patent-No. 95,462, dated v October 5, 186i).-

The Boheduh. referred to, in these Letters Patent and making part ofthe lime.

clear, Vand exact1 descriptiomreference being had. to

the accompanying drawing,fforming part of .this specication', and in which- Fignrefl represents a plan cfa machine constructed in accordance with -my improvement;

.Figure 2,' a vertical longitudinal section thereof; and

Figures-3 and'4, sectional views at right angles to each other, showing aportion1 of the upperpartof the frame, and oneof the -cr'anks .which direct the chains in gear'therewith-.

Similar letters of referenceindicate conesponding' parts.

I nspreading hemp and various-other fibres, and

formingthe same into slivers,` the devices heretofore' employed have been defective in practice, and involved the necessity of lapping. Thns,'in machines as .heretofore constructed, the fspreading and stretching or straightening-action has been produced through a tight -hold upon the hemp, by ldrawing-rolls, arrangedto act in concert with La single endless chain of combing-pins, that,'tra`velling ata reduced velocity to the rolls, con'- ducts the hemp to the latter.4

This causes great irregularity of stretch, is .aptto ibrmknots -or' b pnches, and leave considerablel tow behind between the eombingfpins, and also necessitates' -the use of lappers,.andis1attendant with many otherdisadvantages, all addingto the cost and lahorof heckling theihemp and forming itinto slivcrs. y

My invention obviates these objections, and secures proper combing vand stretching'or straightening oi'- the hempsuccessively at' close'distances or points during thetravel of the hemp through' or over. the frame,

before o'rjn advance of the "drawing-rollaand whilst the hemp is free at both of its ends; and said invention consists in a combination of two. or more series 'of combing or liecklingfp'ins or'teeth',.arranged to travel at different velocities-,and both series of which, .orthatseries only whichtravels at the highest velocity, is carried by endless chains, and arranged so that the points of the pins are presented in or nearly in a plane-surface, while in operation, so that they'operate Yupon the iibres'while the/latter are straight, and with an action like combing, and, not with an action like carding, such as is produced by pins on the surface of a cyiinden'aronnd which the llibres are caused to hng,;

working in series, as specified, upon the' hemp orother fibrous material.

Referring t' o the accompanying drawing- .A ',epesents the feed-board, on to'wliich the hemp or' raw mateiiahas .taken from the bale, without having recourse to lapping, is placed;

B .Bi are two feedhrol'lers, arranged on'orl over the forwardend of thefeed-board. The lower one,`B, of thesev rollers v'rests in fixed journal-boxes, while the upper roller B' works in boxesmade capable of sliding vertically under the control of springs, arranged be-v tween them andthe caps of the bearings.

lhese rollers, or ,the onfe of themfwhichworks '.in" stationarybearings, are slowlyvrotated by any suitable. driving-gear, so as to cause them Ato `drawon the ma` terial from the-feed-board.

D and E represent endless. chainsof heckling-.pins or teeth. These chains' occupy a horizontal position, orltlrereabout, lone iuadvance of the other, and con'm necgigas :it were-the feedfrollerswith the pressing 'and 'delivery-rollers F FI'EF E". of whichfthere mayhe'.

any suitable number.

Said chains travel between the sideframes G G of tlie machine, and are directed by fixed plates or guides H H, and other pertaining parts or devices, as hereinafter more Tully described, the cross-'bars I I of the chains gearing withv chainwheels J J, that are`carried.

' by horizontal 'cross-shafts',- which are rotated -by any suitable mechanism to gi-ve to said chains travel, as indicated by'arrow in 2, and so that the chanE is- .inadeto move faster-than the chain D, `but no faster, and preferably slightly slower, than the pressing-rolls,

which draw or receive Vthe heckle'd hemp from'tlxe chain E. f"

'lhennost forward portion'of th'eframe has arranged across it, vimmediately in front'cf the delivery-end of the lchain E, a stationai'y'clearing-bar, provided with" pins L or teeth, 'between which the pins of the endless chain E wbrk, and that serve to prevent the hemp from lapping round the chain.

The pressingrolls vli to 'F4 rotate as indicated by their respective,arrows.I4 Certain-'of these onlyV may be driven, and they should have in connection. with 'them suitably-arranged tubular condensers or slivergnides, 15o-guide and condense .thestraightened fibres into a. sliver-form, and nallydeliver the same into'a `suitable receiving-can or cans.

VBy these means the sliver is formed dilectlytromthe raw.bre,jby or through tliefone machine, and without having recourse to lappers, and .in thiscon nection th'e dlerentialfyelooities of the chains Danr'fv 'E perform an importantpart, the heckling-chain E gently drawing' upon the material from the chain D, and the fibres thus being combed and-stretched, while loose or free at their ends, and before the same are ltaken hold of by the drawing or pressing-irons.

M is a loosely-rotating reel or wheel, arranged across and over theel-mimi), to 'prevent the,l strip-v ping of the fibres fromoiA the points of the heeklingpinsof said chain'.

Both chains D `and E may be similarly;constructed,

the teeth or pins a `aheingsecuredr in the cross-bars I I of the chains, .which 1in each set or chain are unitedfat or near :their ends,`by the links bfbjof their' 'eszetive'ehans, with freedomfto tnrmfreely in said lIl `ligidiy fitted to ,both or opposite ends or these bars I Liare cranks O 0, whichhave arranged on their onterfaees guide-pins o "and d, that may, if desired, work along suitable grooves inl the guide-plates or sides of theframe,to keep the hecklin'g-pins or teeth in verticalnposition'thronghout the horizontal travel ofthe chains, andthat, in conjunction with cams Pand Q,-1tnrnianddirectthe bars I I in theA .endtravels of the chains,- so that: the pins a a of `each chain yenter the hemp vertieallyfor 'thereahdnts', and leaye it in .like position, which action prevents objectionable lift on entering, v'or drag downward on leaving'. the vihres. ;Furtlermore, it is preferredt'form, in the outside face of each crank O,a slot, that, receiving within it a'projecting'edge of the 'guide-platesH, serves to .snbstantiaily asheren specified.'

vduringtheir engagement withthe material, and further serves to stiii'en or hold the bars I I in aposition Y to insure the same.-

'While itis .preferable to arrangejthe .two series of pinson endless chains,'that both may presenttheir .operating-points in planes, the slower-moving series of pins may be nrrangcd upon a cylinder, butit is absoluteiyessential thatthe quicker-moving series should Vbe arranged to'wo'rk in a' plane.Y l .What is herexolaimed, and desired'to besechred by The combination of v.the vtwo or more endless beltsy of combing orhe'ckling-pins, arrange'done before the other, 4and running at different. velocities with the mechanism, substantially as .herein described, for pre' senting their operating-pointsin or nearlyvin a plane,
