COLLAPSIBLE ROPE $POOL.

Application filed October 13, 1923. Serial No. 668,343.

T 0 all whom it may concern:

Be it known that we, GILBERT G; DAVIS amlMA'rrr-rmv J. DAVIS, both subjects of the King of Great Britain, and both residents of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Collapsible Rope Spools, of which the following is a specification.

Our invention relates to improvements in collapsible rope spools, the objects of which are to provide means whereon a rope or cable can be conveniently wound, and after such winding, the coil may be easily removed therefrom, a further object is to provide such a device as may be connected to the overhanging end of a driven shaft and entirely carried thereby so as to be adaptable for use on and as an auxiliary to existing winding machines such as donkey engines and the like. .The invention consists essentially of a drum freely rotatable upon a driven shaft and having a plurality of slats supported beyond the periphery of the drum andupon which the rope is wound, and. means whereby the slats are withdrawn radially inward that the coil of rope may be removed therefrom, as will be more fully described in the following specification in which F lg. 1 is a general sectional view of our invention.

Fig. 2 is an endview showing the manner of locking the spool in winding position.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates a driven shaft upon the end of which the spool is supported. 2 is a drum having peripheral walls 3 and an end wall 1-, centrally of the drum 2 is a recess forming a bearing 5 into which the shaft 1 is fitted for rotation and also as a support for the spool. 6 is an annular recess in the end wall 4 and surrounding the bearing 5. 7 is a collar suitably fastened to the shaft and rotatable within the recess 6 for the purpose of holding the drum in position longitudinally of the shaft 1. The numeral8 indicates a flange bolted to the end wall 4 and-covering the collar 7, the outer face of the flange is provided with clutch teeth 9, which are adapted to be engaged by the corresponding clutch teeth 10 clutch teeth 10 and 9 tothe drum 2.

The numeral 17 indicates a shaft extend ing outwards from the base of the bearing 5 of the drum 2 upon which is mounted a freely rotatable sleeve 18 havingan external thread 19 thereon, the outer end of the sleeve being secured to a boss 20 having a central recess 21 and a pair of upstanding lugs 22 upon its outer end. Secured to one side of the boss 20 and projecting beyond the end thereof is a spring catch 23. The sleeve 18 and its boss 20 is held in position by a nut 24: and a castellated locknut 25 screwed upon the outer end of the shaft 17, the locknut when in fixed position projecting the depth of its castellat-ions beyond the face of the boss 20* adjacent the spring catch 23.

The numeral 26 indicates a handle upon a forked crank 27 which is hinged to the lugs 22 by the pins 28. 29 is a tongue extending inwardly between the forked members of the crank for the purpose of engaging the castellated nut 25 when the handle is folded, as shown, to lock the sleeve 18 against rotation upon its shaft. 30 is an aperture in the crank through which the free end of the spring catch 23 extends toform a releasable grip to the crank.

The numeral 31indicates a boss having an internal thread 32 in engagement with the thread 19 of the sleeve 18. 33 is a plurality of spokes extending radially and tangentially from the boss 20, the outer ends of each of which are apertured to receive a pin 34. Upon the periphery of the drum 2 are pairs of brackets 35 .in whichare slots 36 sloping towards the axis of the drum and at the outer end of the drum are corresponding pairs of brackets 37 having a pivot pin 38, the purpose of which will hereinafter appear.

The numeral 89 indicates generally, a plurality of slats each having a longitudinal member 40, a right angular member 41 at one end and a fork 42 at the opposite end which fork is provided with a pivot pin adjacent its outer extremity. 44 are rocking arms each having an outer projecting member 45 and a cranked member 46, the member 44 is pivotally connected adjacent its longitudinal centre within the fork 42 by the pin 43 each of the arms 44 being fulcrumed upon the pin 38 between a pair of brackets 37.

The numeral 47 indicates a plurality of links each of which are pivotally connected at opposite ends to a spoke 33 by the pin 34 and to the cranked end 46 of the rocking member 44 by a pin 48.

Having thus described the several parts of our invention we will now briefly explain its use.

When it is desired to wind up a coil of: rope the collar 11 is moved by means of the lever 15 to establish a driving connection with the drum 2 by means of the clutch teeth 9 and 10, the rope is loosely attached to a right angular member 41 of one of the slats 39 so that on the rotation of the drum the rope is coiled upon the slats, the ends of the coil being held in position by the member 41 of the slats 39 and the outer projecting members of the rocking arms 44, the clutch collar is withdrawn when the rope is fully wound and the drum brought to rest, the coil being subsequently bound against unwinding in any suitable manner, the crank 27 is then swung over into the position shown in dotted line in Fig. 1, and the sleeve 18 rotated by the handle 26 cansing the boss 31 and its spokes 33 to move lengthwise of the shaft 17 towards the drum 2 thus bringing the rocking arms 44 to a position substantially parallel with the drive shaft 1 and simultaneously drawing the slats 39 longitudinally outwards of the drum and disposing their longitudinal members 40 at a tangent to the walls 3 of the drum 2 so that the coil may be entirely freed from, binding connection therewith and bodily withdrawn.

After the coil has been withdrawn, a reversal of the rotation of the crank 27 restores the slats in position for further coil winding, and the folding over of the crank causes the tongue 29 to engage a castellation of the lock nut 25 thus locking the slats and rocking arms in winding position.

lVha-t we claim as our invention is:

1. A rope spool comprising a drive shaft, a drum upon the shaft, longitudinal slats carried by the drum each having a right angular member at one end and a pivotally connected member at the opposite end betweenwhich a rope is adapted to be coiled, a threaded sleeve rotatable upon an axial shaft and means carried by the sleeve for moving the pivotally connected members into and out of parallelism with the drive shaft.

2. A rope spool comprising a drive shaft, a drum upon the shaft, longitudinal slats carried by the drum, each having a right angular member at one end and a pivotally connected member at the opposite end between which a rope is adapted to be coiled, a threaded sleeve rotatable upon an axial shaft, means carried by the sleeve for moving the pivotally connected members into and out of parallelism with the drive shaft, and means for locking the threaded sleeve upon its shaft.

3. The combination of a drum provided with a tubular bearing annularly recessed at one end. a shaft extending into said bearing, a collar fixed to the shaft and positioned in the recessed portion of the bearing and a plate secured to the drum and covering the aforesaid recessed portion of the bearing to retain the collar therein.

4. The combination with the structure recited in claim 3 of means for clutching the shaft to the drum comprising clutch teeth carried by the aforesaid plate, a clutch member slidably keyed to said shaft and provided with clutch teeth for said engagement with the teeth of said plate.

5. A rope spool comprising a drum, a plurality of brackets arranged in pairs around the surface of the drum adjacent one end thereof, a plurality of slats spaced around the drum with one end of 'each slat arranged between the brackets of one of said pairs and pivotally and slidably secured thereto, fixed guard projections carried by the aforesaid ends of the slats, movable guard projections pivoted intern'icdiately to the remaining ends of the slats and to portions of said drum and means connected to the movable guard projections operable to shift said projections to a position in line with said slats from a position at an angle thereto.
