Figuren 4 and v5, details lto be referred to. y, A Y A c; I, .Our intention relates to that class of lmachines for laying and twisting rope for which Letters Patentof I the United Statesjvere granted to us on the 28th`day of February, 1844, and-oni thev V25th day of April, '1854, 1

In the former patent astraight crane isv described as being `employed for' guiding the rope as it was wound upon -f 'the 'winding-reelfhut asthe end of 'thecrane traversed' the arc of a circle, therope, when at either end of the 4r'eel,'1vas drawn at such an angleV that it: could not he woiund ivith regularity, while, when -at the centre, the coils,

were'liable to ride upon eachother, .thereby causing delayani inconvenience. We afterward ernployed a curved f crane, having an angular arin'fhing-edfthereto,"ca descifibedA in' ouraforesa'id'lpatcnt of I.1.854, so as no ,cause the rope-tube fdiuadireetion parallel withl thejaxis of the' win'cli'gerce-l.l But although this device answered.- it; ara :nti ifs-'ny' -reompnsiijfmeseafarer@- mns timed fertnsvas complicata and' t Our 'present invention :has for its 'object to overcome entirely the above-mentioned diicurties, aud consists in the-employment, in 'ccnnectin'with acrane, of @guide-Wheel or'pulley', which slideson a horizontal rod o r shaft parallel' with-the exis of the winding-reel, the-rope nassing from the endof `the 'c'raue .overthe slidin/gfl guide fiulley, and thence vto the winding-reehbywhi'ch' means it is guided-accurately, as required to forni aperfeeteoil .j l r l;

Omi invention also consists' inlan'improved device for insuring the regular and equis-l.deliverylr of the strands.

In our aforesaid patent of ,1844, each strand ives-` passed once around afragivheel, these ragwlzeels heilig each `provided ivitha cog-nheelwhich engagedwith s central cogwheel so as. to secure theirsmultanebis revolution. 'The s tra'nds,.hw cver,hivere liable to slip upcn. these rag-wheels as soon 'as ythey becaine `worn', thus causing aul unequal delivery o ftheyarn, Y To overcome this didiculty we pass each. strand several times around jilsm'ooth rcllor cylinder, so este prevent its slipping thereon, the rolls being providedwith gears,

- which engsgeih'lthj'. centralfgear to insure their simultaneous revolution, and atieeter o'r ring provided with vnniiicliiie orinjclines being'applied to' each rollte keep the celsinthei proper position, and preventtheiiig-froni marinera whichlivehave carried ito'nt.A

'.lo enable'cthersskilled in. the art to understand' and use oiirsinvention, ive-will prcceefi'to'describethe i Inthe r said drawings, A-is the' baseiof Athe lmachine, from ivhich rises a. post .or standard, B, an arm,`,G,

{r1-cjietin'g from"the tofl ofi" which supportsthe upper'end of a verticalshaft, D, the lower' extremity of `which -rggidve's'in asnitabl'eibe'arin gv,'al This shaft D carries two circular lplates,'v?1l F, in suitable bearings, in which 'ih ifblfve the 'journals cfthswinging' frames Gr, whzicl'rcar'ry the bobbins l upon which the stranden a're'wound.

,Thcfshort cranks al, vvhi ciiV are attachedto the endsio'f the journals of the swinging frames G, have theirjournals in ai circular plateror ring, H, which `fits overn eccentric, I, the hollow .shaft of which fits over the shaft.

v VA1),'and carries a pulley, e, over which passes a ba which passes over 'the pulleys g h, and over a pulley, seen dotted-in fig. 2, se/oured'to the shaftD, so t as this shaft D is revolved by gearing connected with-the driving-shaft J, the pulley with its eccentric, is 4clved in'an opposite direction, so 'aste cause the hobbin-f' framesG toturn 'on their axes, and thus give theirequired twist 'to .the strands as they are being formed into rope in n rnanner similar to that described in .our aforesaid Letters Patent of 1854 but as this forms nopart of our presentinvention, it will not be further described. The rope j, after being laid, passes overthe pullejs l l to thejaulley K, around which it is .ivound several-nimes, and this pulley is revolved at' the requisite speed by a series of gears, L, connected with the driving-shaft. The rope is then led over the pulleys m n o tothe rosas crane M, whichy consists of a straight, horizontal bar, 6,.and a vertical bar 7, whih s, pivoted to a standard` j), so that thehar 6 will swing freely in a horizontal direction. The rope is led from thfe pulley'. o over the pul leys q t' s t of the crane M, and over a guide-pulley, N, to the winding 'or take-up reel O, which is revolvedhy means of a friction-wheel, P, connected with the gearing L; The guide-pulley Nis provided u'ith 4a hollow shaft, w, iig. 1, which slides freely on a horizontal shaft` or rod, Q; secured between the standards'lft, and parallel with the axis of the reel O; and itwillrhe seen that as the rope'V is vvound up on'the reel O, the guide-pulley N will he moved horizontally on the shaft Q, the crane swingingwith it at the same time, thus insuring the rope being always drawn from the pulley to the reel in aline at, right angles to its axis, Without regard to the portion ofthe reel on which it is being wound, thus preventing all liability of the coils ridingv upon each other, and insuring their being laid on the rail with uniformity and. regularity. This device is simple`and not liable' to get out of order, while the cost of applying it is very trilling. I

We will now prt ceed to describe the manner in which the regular and equal delivery of the strands c is effected.` v, fig. 4, are rolls or short cylinders, of equal diameteigwhich vrevolve on hollow vertical shafts w, forming prolongations of the journals of the bobbin-frarnes G, and each of theserolls v carries a gear, y, which engages with a central gear, S, which revolves loosely on the shaft D, by which means the rolls o'are prevented from revolving independentlyof each other; and these rolls are held in place on the shafts 'zo by means of bent guide-piecesa, screwed on to their upper ends, as seen in figs. 2 and 4. 4The strands lc areled from the bobbinsnp through the hollow shafts w, and down over the grooved 'portions 8 of the bent guide-piecesfa-r to the rolls v, around which they are wound five or six Vtimes to prevent them from slipping, and arethenee led' up over the grooved portions 9, and through the openings in the cross-bars 10 to the point vhere the rope is being laid." And it will thus be seen that as the strands c are wound around Athe rollsrv La suilioient`nu1nb'er- `ot' times toA prevent them from slipping, andas the rolls are of the Vsame diameter, and are all caused to revolve simultaneouslyat an equal speed by 'means ofth" gears above described, the regular and equal delivcny of'the strands is insured as required to form perfect work, and the rollsv being placed above the'plate. E, are always in a convenient and accessible position.v b are rings, the under sides of which are inclined `at 11 12, solas 'to fzorm eeters, and these fleeters are applied to the rolls v soas to cause the strands to'lbe wound up regularly thereon, and prevent the coils' from riding upon eachother as the rolls are revolved. The ieeters b', Awhichjit loosely on the rolls v, are. kept in placeand prevented from revolving with them by projections 13,-which'resit against the guidefpieces a', and,` as an incline is lformed 'on each side of the projectionl, thefstralidsuiay bu wound around the rolls, either to the right or the left, `as may be desired. v

. Claim. Y

What we claim as our invention, and desire to secure by Letters Patent, is- A `',ihe slidng'guide-pulley N,in combination with the crane-M and the winding-reel'O, operating Isubstan'- tially asdeseribed for the purpose set` forth.

We also claim the rolls v, so arranged as to revolvesimultaneously, the guide-pieces a', or their equivalents, for the purpose of insuringthe equal deliver tially as described.
