My invention relates to a line spooler of the f 1 as to the different convolutions on the drum.
An object and feature of my present invenv tion of the hydraulic line spooler relates in part to the control of the pressure onhydraulic fluid l as it is transferred from one end tothe other of `a hydraulic cylinder through the medium of the pulleys or rollers engaging the cable being thrust from side toy side due to the windingv of the cable on or off the drum. This control pressure develops a thrust sidewise on the cable vto force the convolutions into close contact. A
further feature of my invention vis in the construction of the by-pass control with a valve reacting against springs which thus regulate the opening or passage for the liquid as it is trans- `r ferred from one end to the other or a cylinder by a moving piston. In this connection a more detailed object and feature of my invention is `constructing the by-pass control in the form of a small cylinder with a plug valve therein, such.
plug valve operating through a port from one side to the other and travelling against the reaction of a spring on each side of the valve, thus by using springs of the desired strength, the force required to displace the valve may be made 85' of a suitable value and thus control the lay-pass of the liquid.
Another object and feature of `my invention relates to the manner of inter-linking the pulleys orvrollers which engage the cable and the piston of the hydrauliccylinder to reciprocate such piston and thus displace the liquid. An object and feature of this connection is the employment of a long lever which has the pulleys or rollers pivotally mounted on its outer end,
such pulleys forming a travel guide for the caf ble. A pin or stud fixedly mounted on the lever and which thus swings in an are operates an anti-fraction bearing operating vertically in a travelling carriage, this latter being connected 5 site cross heads connected to such rod and a double piston rod connected to the cross` heads, I reciprocate the piston in the hydraulic cylinder causing the by-pass of the liquid from one end Il of the cylinder to the other. Another feature to a reciprocating rod, thence by means of oppooffmyinvention relates `to the pulley or roller mount for engaging the cable in .which a rod is slidab-ly mounted on the outer end of the lever for the purpose of spacing the pulleys or cable rollers variable distances from the lever 5 as the windings buildup or reduce in diameter on the drum. Another feature relates to lthe pulley engagement With the cable including a pair of rollers engaging one side 0i" the cable and a single adjustable roller engaging the op-y 10' posite side, thence by adjusting thesingle roller the desired pressurel may be exerted on the cable between the group of three rollers.l
My invention is illustrated in the accompanying drawings in which: 15

Fig. 9 is a vertical transverse section on the 40 line Q--Q of Fig. 8 in thedirection ofthe arrows.
Fig. 10 is a verticalV section on the line lil-l0 of Fig. 2 or 11 showing the guide for the travelling carriage connecting the moving rod and the pivoted lever. v Fig. ll is a horizontal section of Fig.v 10 on l the line ll-ll taken in the direction of the arrows. y l Fig. l2 is a detail section on the line lf2- I2 of Fig. 2 in the` direction of the arrows showing 50i end plates l5, each being similar and having an opening therethrough. Each plate has an upward extension I6 for a purpose hereunder designated. Each plate I5 has a large opening Il' for the main cylinder assembly 28. This assembly includes a cylinder 2| threaded at its opposite cured to the outer ends of the piston rod there lare cross heads 35.
These cross heads are in the form of bars 36 clamped together by rivets -or screws 3l. Thus, by their lower jaws 38 engaging the ends of the piston rods, their upper jaws are clamped to a long reciprocating or comple-` mentary rod 8. A positive movement given to the rod i8 which operates through perforations in the upper end l@ of the end plates l5 and over roller guides 4l is secured to the plates l5,
is operative through the medium of the cross heads 85 of reciprocating the piston rod 33 and thus the single piston 38.
The positive movement is communicated to the reciprocating rod 18 by a lever assembly 50 which develops an oscillating movement due to the winding of the cable on and oi of a drum.`
This assembly employs a long lever arm 5| pivoted at its lower end to a pintle bolt 53 secured to a lug 5d on the base liange |3'of the angle l2. This lever has a straight Vertical section 55, an outward bendv58 and a vertical section 5'! with a guide eye 58 at the top.
The roller or pulley mount 88 has a supporting pin 6| which is slidable in the eye 58, such eye having its axis transverse to the axis of the main cylinder 2|. There is a stop head 82 at the inner end of the pin and a somewhat triangular shaped plate 83 secured to its outer end by means of the collar Bil and set screw 85. A friction brake clamp assembly |58 employs a bracket |6| attached to the side of the eye 53. This has two supporting pin El. A lining |63 fits inside of the shoes. These are regulated as to adjustment by the shoes having projecting tongues |64 with .of this roller.
a clamping bolt extending therethrough and also through an eye B55 extending from the eye 58,.thence by means of springs ll a resilient pressure is maintained against the brake shoes and this may be regulated by tightening or loosening the bolt. This friction restrains the pin 6| from rotation and also from longitudinal recip` rocation asto the eye 58, however thebrake or` clamping action is not sufficiently tight to prevent the necessary movement.
On the plate 53 there are mounted three rollers, 6l and 68 being located on one side and the larger roller 59 on the opposite, therefore these rollers are in eiiect mounted on the corners of the triangular plate 53. The particular attachment of the rollers is illustrated in Fig. 5 in which the ,headed axle bolt 'i8 and provided with a shoulder 'll is clamped to the plate 53 by a nut 'l2 threaded on the end. A washer 73 bears against the plate. .As to the roller 58, there is provided a slot 'lil arranged radially to permit adjustment The other rollers 61 and 68 are The piston 30 is` located in a xed position. Each of the rollers has an annular groove 'I5 to accommodate the cable 16. It will be apparent that as the rollers v 61 and 68 are not adjustable they may be riveted to the plate 63.
By having the larger roller 69 adjustable, the cable maybe readily threaded or tted through the assembly of rollers or pulleys and then the roller 88 adjusted to have an operating engagement with the cables. Therefore as the cables lead to one side or the other, that is, oscillateb-etween the left and right dotted line position through the full line position of Fig. l, the pulley mount may oscillate on the pin 6| in the eye 58. This pin also has a sliding motion in the eye to accommodate the build up of the cable on drum, that is, the Winding having different effective diameters. This motion is illustrated by the full and dotted line positions of the pulley mount 88 y 20 in Fig. 2.
Motion is communicated by the lever assembly 5! through the medium of a travelling carriage designated by the assembly numeral 88, note Figs. .l0 and il. This employs a sleeve 8| iitted on the rod 48 and clamped tight thereto, preferably structure 85. This has a back plate `86, two vertical sides 81, inturned iianges 88, thus forming a pair oi opposite vertical channels 89. The back plate also has a Vertical recess 9i) denedb-y the vertical straight line edges@ A pivot assembly employs a pivot bolt 96 which extends through a perforationvl inthe section 55 of the lever 5| i and has a nut S8 threaded on its-outer end. The
races. A sleeve |89 is iitted between the inner race and the section55 of the lever 5|.
In view of the fact that the bolt 86 moves through an arc indicated by the dotted lines lill),l
Fig. l, and the sleeve 8| of the carriage assembly 88 has a straight line motion, it is apparent that the head 99 of the bolt has a verticalmotion relative to the vertical channel 98 formed as a recess, however, the frictional resistance to this bearing' |85 which operates in the larger channels 89. There is a slight clearance of the outer tween the inside face of the sides 8l of vthe cha-n-v 25 at the central position by a set pin 82. On the iront of the sleeve there is a vertical channel vertical motion is overcome by the anti-friction nel 89 so that ,v in one direction of movement there will be a pressure of the anti-friction bearing against one of the sides 8'! and in the motion in the opposite direction, the pressure will be against the `opposite side. This allows for the slight vertical rolling motion. The head 99 has no Contact with the channel 98, therefore by this construction, as the long lever 5i is forced lin'its loscillating motion from one side to the otherA throughthe medium of the collar 8| and the carriage assembly 88, the rod 4|) and the assembly of the cross heads -35 and piston 38 is caused to reciprocate in the cylinder 2|. The control-` lable pressure for this; reciprocationis by means of a by-pass assembly H5. At eachv end of the cylinder 2| and inside of the plates l5 there are two pipes H6, note Figs. land 6, these beingv outside of the stroke of the piston Aso that they are never covered by the cups fof thev piston. Horizontal pipes Ill are connected to the verpass designated |30 includes a plug 3| which,
is cylindrical as to its periphery and made substantially the same thickness as thek partitionv |25. This has a close sliding lit in the port |26.
Oppositely extending valve stem rods |32. are either formed integral or extend from opposite sides of the plug |3| and have their outer ends each journaledl in a sleeve |33, such sleeve being integral with a perforated plate 34. The periphery of the platev is circular and may slide in the cylinder |2|, however each plate is maintained in adjusted position by an adjusting screw |35 threaded through anv opening |36 in the ends |23v of the hollow heads |22 and has a rotatabley neck connection |31 to thevend |38 of the sleeve |33, the inner ends of the screws having upset heads. On account of there being two of these perforated plates each' with their sleeve and adjusted by the screws" |35, these sleeves may be adjusted in the cylinder |2| and as shown in Fig. 8 are in their outermost position in contact with the inner end of the skirt |24 of the hollow heads |22. 'Ihe valve rods |32 have a sliding motion in the sleeves |33 and are restrained in this motion by compression springs |39 of which there are two coiled on the rods |32 on opposite sides of the plug 3| and engaging the perforated plates |34. rThese springs when the hydraulic pressure is equalized centers the plug |3| in the port |26 of the partition |25.
In operation, as the lever 5| is forced to one side or the other from its central position, manifestly it moves the piston 30 towards one end of the cylinder 2|, thus requiring the rtransfer of the oil from one end of the cylinder 2| to the other through the by-pass valve assembly |20. The oil flows freely through the perforated plates |34 but on the pressure side meets the resistance of the plug |3| tting in the opening |26. The pressure however displaces the plug acting against the'compression of one of the springs |39 so that the plug is completely displaced from the opening allowing passage of the oil around the periphery of the plug and thence through the communi-- cating pipe and ||6 to the opposite end of the cylinder 2|. Of course when the plug is being displaced and compressing the spring on one side, the spring on the opposite side urges the movement ofthe plug in its motion under pressure of the liquid on one face of the plug. When the piston is at the complete end of its stroks or moved as far as theA traverse of the cable on the winding drum causes the movement of the piston, as soon as there is equilibrium of pressure in the cylinder, the springs |39 cause the plug |3| to again become centered in the opening |26 and the reverse action takes place when the arm 5| is moved positively in the opposite direction.`
Various changes may be made in the details of the construction without departing from the spirit or scope of the invention as dened by the appended claims.
