Claims. 1
This invention relates generally to winding or 'spooling devices for cable or the like, the invention having particular application to winches, windlasses, hoists and analogous mechanisms for Winding cable on drums or spools especially in connection with operations in which a heavy object attached to one end of the cable is to be pulled, hauled or hoisted from one locality to another.
An. object. of the invention is to provide an improved winding or spooling device having means for controlling the. convoluticns of the cable as it is wound on the drum or the like so that the convolutions or windings will lie snugly together and uniformly across the effective width of the drum.
A further object of the invention is to guide the cable to the. drum, as the latter revolves, in such manner that each winding or convolution of the cable will form in. uniform manner closely contiguous to the previously formed winding across the effective, Width of the drum and further in which the windings will. automatically form in uniform level layers or courses as the winding operation. proceeds.
Still a further object of the invention is to provide a winding device, winch or the like having an improved travelling guide or spooling device comprising a carriage and a guide pulley mounted thereon and over which the cable or rope is led to the drum, the guide device being constructed and movable in such manner, as the windings form across the. drum, as to maintain the lead portion. of the cable running from the guide to the drum substantially perpendicular to the drum axis at all times, and theguide pulley being pivotallzv mounted on the carriage in such manner as to automatically position itself in proper engaging relation to the cable in any position of the' carriage, thereby preventing damage to the cable and ensuring smooth and free operation of the spooling device.
Another object of the invention. is: to provide improved means for guiding the cable or rope to the winding drum in a direction constantly at substantially right angles to a plane passing through the drum axis, as a result of: which each convolution is forced by the previous: convolution.
or winding into place snugly therea'gainst which action proceeds. uniformly back. and forth across the drum enabling any desired. number of layers or courses to be. formed smoothly upon the drum.
By virtue of the invention. therefore; the full winding capacity of the drum may be availed of gems in connection with winches or the like for winding steel cable as to which great difficulties and disadvantages have been encountered in the use of conventional winches or Winding devices. In the. operation of Winches, such as for Winding steel cable, the cable will not wind smoothly or evenly upon the drum unless exceedingly great care and pains are constantly taken by trained personnel to guide and. direct the lead portion of the cable properly to the drum. This is attempted, usually unsuccessfully, by using tools to pry the cable along the drum during the winding operation. Even then it is a very slow, tedious and difiicult operation. Unless this can be done, which in fact rarely is the case, the cable will bunchup on the drum, the windings will cross one another forming a hump and eventually when a coil or winding slips off the hump there is danger of damaging or cutting the cable. Snarls and kinks in the cable readily form unless great care is taken by the operators in charge of the work, and. such snarls and kinks weaken the cable. Damaged. cables frequently break or sna and the broken end often flies out and injures nearby workmen. If the cable bunches up "on the drum it reduces. the winding capacity of the drum, i. e. theamount of cable that may be wound thereon; Furthermore, after such an operation, Where the. cable. bunches and snarls on the drum, it is necessary to unwind the cable and re-wind it on the drum. All of these makeshifts aretedious and time consuming. Further- .more, conventional practice is especially dangerous where steel cables subject to great load stresses and strains are being wound. Moreover, the breakage of cables materially increases the operating. costs.
An important object of the invention is to overcome. the foregoing difficulties by providing a relatively simple, compact and efficient means for controlling the cable windings on. the drum and which is adaptable to various types of winding devices while requiring but little. space for installation and no; greatexpense to manufacture. By virtue of the invention the danger of damage to the cable is minimized; the useful life of the cable is prolonged; the winding operation may be conducted at any practicable speed and with safety; operation time is greatly reduced; excessive stresses on the winch mechanism due. to bunching of the. cable are eliminated; and labor costs are materially reduced.
Other objects of this invention will appear in the following description and appended claims, reference being had. to the accompanying drawingsv forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
In the drawings I have illustrated by way of example, several embodiments of the invention as applied to a winch or winding mechanism of any suitable type which is provided with a drum or spool preferably power driven for the purpose of winding cable or the like thereon. In these embodiments the guiding mechanism for the cable, by means of which the cable windings on the drum are controlled, comprises a guide pulley at one side of the drum supported to travel on a track in a curvilinear path in the general direction of the drum axis and a second guide over which the cable passes to the travelling guide pulley and which is supported at a fixed point or locality in spaced relation both to the drum and the travelling guide pulley. The contour of the track and location of the fixed guide are preferably such that the lead-in line from the travelling pulley to the drum is maintained substantially perpendicular to a plane passing through the drum axis and in any given position of the travelling pulley on its track, the pull or tension forces exerted on the travelling pulley by the two lines of cable running to and from the travelling pulley will substantially balance. Hence, during the winding operation the cable as it is wrapped around the drum will be forced or thrust laterally by the preceding convolution so as to lie contiguous thereto, and this lateral shift of the cable on the drum will exert a force in the same lateral direction shifting the travelling pulley on its track so as to automatically position the lead-in line substantially perpendicular to a plane passing through the drum axis.
Thus, it will be noted that the cable at the locality where it is tangent to the Winding surface on the drum is progressively forced or pushed laterally by the adjacent convolution through what is akin to a camming action and at the same time the travelling pulley is progressively shifted in the same direction on its track into successive positions tending to bring into balance the pulling forces exerted on the pulley by the lines leading from the fixed guide to the travelling guide pulley and thence to the drum. It will also be noted in the various embodiments that the lead-in line from the travelling guide pulley is constantly maintained at substantially the same angle to the drum, i. e. normal to a plane passing through the axis thereof or approximately so, whereas the secondary lead-in line extending from the fixed guide to the travelling pulley progressively changes its angle of di-- rection. Moreover, the curved profile of the track for best results is preferably such that in all positions of the travelling guide pulley the length of cable extending from the fixed guide over the travelling pulley to the drum is at all times substantially a constant.
Inasmuch as the winch or Winding device embodying the present invention may be used for a variety of purposes it will be understood that it may be supported either on a stationary or a moving structure depending upon the use of the device and the nature of the work to be performed. Motor driven trucks or tractors are frequently equipped with winches and hence for convenience in illustrating one embodiment of the invention, without however limiting the scope or use of the invention, there is illustrated in Figs. 1 to 3 inclusive a motor driven truck 20 equipped with a winch constructed in accordance with such embodiment. This truck is of conventional type having a restricted or relatively narrow space 2| between the cab 22 and the cargo receptacle 23 thereof. Mounted Within the space 2| is a winch or winding device, generally indicated at 24. which is constructed in such manner as to permit its use within the relatively narrow space 2|. The Winch or winding device comprises suitable transversely spaced upright side frames 25 each of which may be made in two parts bolted together to form spaced bearings 26 for a transverse rotatable drum shaft 21 to which is secured a drum or winding spool 28 provided with a cylindrical portion 28a between the end flanges thereof upon which the cable is to be wound. The drum shaft and hence the drum 28 is preferably rotated at the desired speed by suitable power driven mechanism such as by an electric motor and reduction gear unit l9.
Spanning the upper ends of the uprights or stanchions 25 are two spaced rails 29 which are rigidly secured, as by means of bolts, to the upper ends of the side frames 25. The upper surfaces of the rails 29 are correspondingly curved to provide curved tracks or tracking surfaces 29a extending generally in the direction of the drum axis and preferably somewhat beyond the opposite ends of the drum. The preferred manner in which the curve of the tracks 29a is determined is hereinafter set forth. Mounted to travel along the tracks of the spaced rails 29 is a cable guide unit which for convenience may be referred to or termed a travelling guide. In the embodiment shown in Figs. 1 to 3 the travyoke or support 32.
amass elling guide comprises a carriage including; a base frame so; of any suitable. construction upon which is mounted a set of four flanged rollers or wheels. 31., these wheels being arranged in two pairs spaced longitudinally of the rails. Secured to the carriage frame 39 is a bifurcated pulley support: or yoke 32 between the ends of which is mounted a rotatable guide pulley 33 secured toa shaft 34 which is revolubly' supported by the Secured to opposite ends of the rails 29 are upright stop members 23b adapted to be engaged by the carriage wheels 31 so as tolimit the travel of the carriage when it reaches one end or the other of the tracks.
Bolted to the flooror platform of the truck 1 beneath the drum 28 but in the present instance a short distance to the front thereof is a bifurcated bracket 35' between the ends of which is located a yoke 36. This yoke is mounted for transverse pivotal motion upon a shaft or pivot pin 31 carried by the bracket 35. A guide pulley 38' for the cable 39 is rotatably mounted between the sides of the yoke 36 by means of a pivot pin or shaft carried by the yoke. In the particu-' lar installation shown in this embodiment the end of the cable 39 is attached in any customary manner to one end of the drum 2-8 and from the drum the cable passes over the pulley 33, thence forwardly and downwardly over the pulley 38 and thence rearwardly beneath the receptacle 23, the cable passi-ng'th-rough guide rollers M beyond the rear of the truck and terminating in a coupling or any other suitable device by means of which the cable may be connected to an object to be hauled or drawn toward the truck by winding the cable upon the drum.
From the foregoing it will be seen that the guide mechanism for controlling the windings or convolutions of the cableon the drum comprises a guide pulley 3-8 which, although pivoted to permit lateral swinging thereof in order to line up the groove of the pulley with the cable leading therefrom, is mounted at a fixed point or location 31' and hence this guide is herein termed the fixed guide since it is supported at a fixed point with respect to the drum 28. In this embodiment the pivot 31 of the yoke 36 which supports the pulley 38 is located at a point on a line extending perpendicularly to the drum axis and passing through substantially the longitudinal center of the drum. From the pulley 38 the cable is led past the drum over the trayelling pulley 33, the portion of cable extending between these pulleys being termed for convenience the. secondary lead-in line. pulley 33 the cable passes to the drum 28 for winding upon the cylindrical drum surface 28a and the portion of cable extending from the pull-ey 33 to the drum may be termed for convenience the primary lead-in line. The angularity of the secondary lead-in line 2912 with respect to the drum axis varies as the winding of the cable proceeds but the primary lead-in line 35a isat all times maintained substantially perpendicular to a horizontal plane passing through the drum axis. Thus, as the cable is wound upon the drum the carriage upon which the pulley 33 is mounted will travel along the curved tracks 29a so as to. maintain the lead-in line 39a substantially perpendicular to the horizontal plane passing through the drum axis. As a result, each convolution or winding will be formed contiguous to the preceding convolution and the cable will be. wound evenly back and forth over the drum.
The: embodiment of the invention illustrated;
From ther in Fig. 4 is the same as that. illustrated in li'igs. t to 3 inclusive. excepting as to the relative arrangement of the guide pulley 38., the travelling pulley 33 andthe drum 2:8. In v this instance the fixed guide pulley 38 is mounted below and to the rear of the .dnnn 28 and the travelling guide pulley 33 together with its carriage and the guide rails. 29 is mounted above but somewhat. to the rear of. the drum. This embodiment; may be suitable in some instances where space re!- q-uirements necessitate a different location of the cable guiding mechanism from that shownv in Figs. 1. to 3 inclusive. Inasmuch as the opera.- tion of themechanism shown in Fig- 4 is the same as that previously described, this embodiment further illustrates the flexibility of the invention in regard to the relative location of the fixed guide, travelling guide and drum.
In Figs. 5 and 6 there is illustrated a somewhat modified construction in respect to the travelling guide mechanism, which construction may be used in lieu of that illustrated in Figs. 1 to 4 inclusive or in connection with any other embodiments of the-invention. In this instance the travelling guide mechanism comprises a carriage 42 formed of diverging frame members at the outer ends of which are r-evolubly supported two pairs of flanged wheels or rollers 43; Be.- tween these wheels is arranged a supporting yoke 44 on the outer end of which is journalled a shaft 45 to which is secured a grooved pulley 46. The frame members of the carriage 42 terminate centrally in a hub 42a bored to receive a swivel or rotatable shaft 41 having a bearing within the hub and to which the yoke 44 is secured. The lower reduced end of the swivel shaft 41 passes through a retainer strip or bar 49 which spans the lower edges of the rails 29 and the shaft is held in position by a nut 48. The retainer bar ie is incorporated in the structure for the purpose of preventing the travelling guide and its carriage from becoming disconnected from the guide rails 29. At each end of the rails 29 at a point therebetweenis a stop 50 which may take the form of an adjustable set screw adapted to be engaged by a stop 5| on the carriage 42 at each limit of its travel. The stop 58 may be adjusted toward and from the carriage in order to limit its travel to the desired point at the end of one row of windings on the drum so as to cause the direction of winding of the cable to be reversed at the end of the drum at the proper point.
In the embodiment illustrated in Figs. 7 and 8 there is illustrated a modified form of fixed guide pulley over or from which the cable 39 is led to the travelling pulley. The construction shown in Figs. '7 and 8 may be substituted for the corresponding fixed guide structure illustrated in Figs. 1 to 4 inclusive or maybe incorporated in any" of the embodiments of the invention. In this instance the fixed guide structure comprises spaced base or supporting members 52 between which is disposed a ring or other shaped yoke 53 I journalled at opposite'sides in the supporting members 52 as by means of aligned pivots 54. Arranged within the yoke 53 and free to turn thereinis a centerring or other shaped yoke 55 whichis journalled at'opposite sides in the outer yoke 53 as by means of aligned pivots 56. The
cured an outwardly projecting pulley yoke 58. The fixed guide pulley 38 is secured to a shaft 59 'journalled in the outer end of the yoke 58. The
may be led to the pulley 38 in a direction both inclined to the horizontal and also from the side of the drum, such as illustrated in Fig. 11. In such instance the pulley will swivel in order to dispose the groove of the pulley in a plane lined up with the incoming cable and at the same time the supporting yokes 53 and 55 will tilt sufficiently to accommodate the inclination and the angle of the incoming line. In this embodiment, however, it will be noted that the pulley 38 is supported at a fixed point or locality by means of the pivots 54 journalled in the fixed supports 52 and, hence, for convenience in description this pulley 38 is termed a fixed guide since it is basically supported at a predetermined fixed point or location.
The embodiment illustrated in Fig. 9 is in most particulars substantially the same as that previously illustrated and described and also as later described in connection with Fig. 10. This embodiment illustrates the application of the invention to a construction where the fixed guide is not located in line with the longitudinal center of the drum but, for example, beyond one end thereof. A construction as shown in Fig. 9 may be desirable in some instances in order to suit space requirements of the installation; In the embodiment of Fig. 9 the curved track is formed by spaced rails 69 which support the travelling guide comprising carriage G2, flanged wheels 43, swivel pulley yoke 44, and guide pulley 46. The construction of the travelling guide is preferably similar to that illustrated in Figs. 5 and 6. The fixed guide comprises spaced grooved guide rollers 6! between which the cable 39 passes. These guide rollers are journalled at fixed points Bio and the cable leading to these guide rollers passes through a pair of vertically spaced guide rollers 62. The power driven winding drum construction may be substantially the same as that previously described. The curvature or curved profile of the tracking surfaces of the rails 60 may be determined in the same manner as in the other embodiments and as later described in connection with Fig. 12, since this profile, due to the location of the fixed guide BI is taken as a part of a complete curve or profile symmetrical about a plane passing through a point centrally between the pivots Bid and perpendicular to the axis of the drum 28. The portion of the complete symmetrical track profile needed for the travel of the carriage 42 is determined by the width of the drum 28.
The embodiment illustrated in Fig. 10 is very much similar to that shown in Fig. 9. In both instances the track guide for the travelling pulley .is located at the opposite side of the winding drum from the fixed guide. The construction in Fig. 10 difiers from Fig. 9 in that a full symmetrisuitably supported at opposite ends through the medium of stanchions or other supporting members 54. On the carriage 65 are revolubly supported two spaced pairs of flanged wheels or rollers 66 adapted to travel upon the outer curved tracking surfaces of the rails 63, this construction being substantially the same as that previously shown and described. Arranged between the winding drum 28 and the rails 63 is a pulley yoke 51 swiveled at 68 within a bore in the hub of the carriage 65. The swivel shaft 68 has a bearing in this hub in much the same manner as the construction shown in Fig. 5 and the carriage and yoke are held in position against disconnection from the rails by means of a transverse retainer bar 16 spanning the rails and a nut 69 threaded onto the end of the shaft 63. A grooved pulley H is journalled in the bifurcated ends of the yolre 61, and since the yoke is swivelled the pulley may turn relatively to the carriage to suit the angularity of the lead-in lines. The fixed guide over which the incoming line passes is the same as that shown in Fig. 9 and comprises spaced grooved pulleys 6! between which the cable passes and a pair of vertically spaced guide rollers 62 arranged immediately in rear of the pulleys 6|. As distinguished from the embodiment shown in Fig. 9, a vertical plane passing through a point lying centrally between the pivots 6|a will bisect the winding surface of the drum 2B and will pass through the symmetrical center of the curved tracks 63. In view of the construction shown in Fig. 9 it will be seen, however, that the fixed guide may not only be located in front or in rear of the winding drum but may be located at various locations at one side or the other of a plane passing through the center of the drum.
The embodiment of the invention shown in Fig. 11 shows an application of the invention using a travelling guide of the swivel type shown in Figs. 5 and 6 mounted to travel along a curved track 29 in substantially the same manner as shown in the embodiment of Figs. 1 to 3 inclusive. Moreover, in Fig. 11 the fixed guide is of the type shown in Figs. '7 and 8 which is mounted below and to the rear of the winding drum 2B, somewhat in the same manner as shown in 1 to 3 inclusive. It will be understood that the winch mechanism proper may be of any conventional type, either power driven as previously described or operated in any suitabe manner to wind the cable 39 upon the drum. The fixed guide in the embodiment of Fig. 11 functions in the same manner as described in connection with Figs. 7 and 8, the pulley 38 not only being swivelled to turn to the desired angle to accommodate the angular direction of the incoming line but also mounted for limited universal movement in transverse directions.
As previously stated, for best results the ourvilinear contour or profile of the track for the travelling pulley is such that in all positions of the pulley the lead-in line to the drum will remain in a plane substantially perpendicular to the axis of the drum and the length of cable extending from the fixed guide over the travelling pulley to the drum will be substantially a constant. It is my belief that in order to achieve most efiicient operation of the winding device the track curve or profile will vary somewhat from a true arc, and in my opinion the following method may be followed in developing a formula which may be satisfactorily used in laying out the desired curve for the track.
Referring to Fig, 12 the point 0 is predeter- 575 -mined and represents a fixed point through which or from which the "cable is drawn before passing over the trolley pulley and being. wound on the drum. .InFig. 10 the fixed pointis "between the pulleys 161. In :Figl 11 thevfixed'point is approximately at the intersectionof theextended axis of the cable39b and the axis of thejournal bearings 54 of member 53. Point-O isthe point oftintersec- .tion of the .cableline 3912 'with'the pivot-3:1 in (Fig. 201 with the pivot 54in Fig. 7.
It-will be seen that the fixedgpoint :lies on ,a line I00 perpendicular to-aplane passing through the axis l [H and this line lies in a ,plane bisecting the drum. The track curve T to -be developed symmetrical about the center point C ofv this curve which also lies on the line I00. Theposition of the travelling pulley and .its distance from the drum are also initially determinedit beingnoted from the drawings and the yprevious description that this pulley and the-track may be located above or at either the front or rearof thedrum. In the schematic illustration in Fig. 12 a predetermined position of the travelling pulley 33 is shownas also the related position of the swiveled pulley-46 01 l I. The .pointP represents the inter section of the angularlyvrelatedprimary-and secdrum axis I'M, or toa planepassingtherethrough,
