Patentedy oct. 11, 193s i UNITED STATE PORTABLE REWINDING MACHINEy Osborne I. Price, Frederick, Md. ,l y Application June 25, wssgserial No. :57,303Y solaires. (c1. 242-1) f f My invention relates broadly to line-throwing equipment and moreparticularly to a portable rewinding machine for rewinding lines after they v have been projected.

v One of the objects of myinvention is to pro-y vide a construction of portable krewinding machine for lines, which is simple in its construction and relatively light in weightand vwhich is adapted to quckly rewind a line after it has `been projected. A Q

Another object of my invention vis to provide a construction of` rewinding machine for lines having means for accurately guiding the line upon the storage spindle in 'ai rewinding process 4for insuring the quick return of the line to the spindle, with minimum entanglement-.of the line.

Still another object of my invention is to provide a construction of tensioning meansfor uniformly guiding a line vupon the storagespindle of a portable rewinding machinefor insuring quick restoration ofthe line tothe spindle in uniformly tight loops about the spindle.

A further object of my invention is to provide a' construction of cam mechanism,` operative through a reduction'gear for controlling the reciprocatory travel of a line guide with respect to the linestorage spindle.

A still further object of my invention is to prol vide an arrangement of rackand pinion system,

interposed between the reciprocatory cam control mechanism and the' line guide in a rewinding machine for predetermining the rate oftravel of the line guide withv respect to the rotation 'of the lineV storage spindle. f

StillY another object of my invention `resides in the construction of light, compact Aand portable line rewinding machine, which may be readily moved into position upon the deck of a ship, for` rewinding a projected line, and suitably housed for'protection of the moving parts against the elements. 1

After the line has been used, the line may bel subject to entanglement and knotting. However, with the machine of my invention, the line may be quickly rewound so as `to be ready for instantY use for thenext shot. The rewinding apparatus of my invention is readily portable and is extremely light in weight so that the apparatus r may be shiftedrto any desired position for use on the deck of a vessel or in places Where space is limited. The mechanism is extremely simple so that the manufacture of the apparatus is inexpensive and there are but few parts to be replaced because of wear. I provide several different forms of my invention and for the 'pur' pose ofillustration, Ihave shown two of lthese forms. One form of the inventionY comprises a small lightweight machine capableof rewinding a rope of relatively small size of a length of from 500to Y"IOOifeet rwithin a very short time. In the larger size'rewinding machineillustrated herein,

the rewin'ciing mandrel or spindle will accommo-` date a much heavier rope of much greater length.

Because of the diiference in sizeof the ropeV adapted to be rewound by the diiferent machines, the larger size machines are equippedfwith a driving gear for` the rope guide adapted. to drive the rope guide a greaterdistance and at a dif.

ferent rate thanis the casewith the rope. guide in the smaller size machine. Forthis purpose, I provide a gear rack and pinion system interposed between the reciprocatory mechanism which carries the rope guideVV and the ropev guide immediatelyadjacent the coil 'of rope on Vthe spindle.4V The reciprocatory mechanism includes a 'cardioidY shaped cam adapted to reciprocate the guide mechanism adjacent the spindle on which the rope is coiled. The'spindle includesspecial'means for retaining the rope in .position'thereon and special means for tensioningthe rope` as'it is guided upon the coil carried bythe spindle. For handling different Vsize ropeg'I provide different kinds of tensioning means. For the smaller rope, I may provide guide and tensioning means which are very'compact.' For the larger size rope, I provide Ytensioning and4 guide 'means adjustable in position and adapted to guide the rope in proper tensionupon the coil.Y

Referring to the drawings indetail, reference character I indicates the base of`one form Aof the rewinding machine of my invention.` The base I' is pressed from. sheet metal and'is supported by the metallic angle members 2 lforming supporting feet.Y There is an aperture 3 in one corner of the base which servest receive theV storage 'roller in' removing the coil therefrom' when it is desired to'take off the coiled rope which has been received on the storage Vrolleror mandrei'. I provide a c'over'l which serves to protect Ythe rewinding equipment from the elements. andthe weather andthe sea. The cover 4 provides an enclosure' which is'hinged at 5 by means of hinges secured'lto the Vbase I through means indicated at 5a. Ahasp I5v is secured to the base I and is adapted to Vbe looped over the hook 8 on the 'cover 4.Y 'A suitable catch I is adapted to be latched through'the loop 8 in order 4to maintainA the cover 4 'in position. A handle@ is arranged'for carrying the rewinding equipment. The base I carries'fa' standard Il]- adjacent one end thereof and a triple standard I I adjacent the other end thereof'as shown. There is a central vertical bearing extending through the triple standard II as shown at I2 and in the bearing I 2, there is journaled a vertical shaft I4.

The vertical shaft I4 carries a bevel gear I5 at the upper extremity thereof secured by any suitable means such as set screw I5 whereby the beveled gear I5 is adapted to be moved in unison with'the shaft I4. That is to say, by driving gear I5, rotary motion is imparted to the central shaft I4. There is a keyway I'I which is adapted =to ibe aligned with a keyway I 8 formed in the hub I9 of the cardioid shaped cam indicated at 20.- The hub I9 of the cardioid shaped cam 20 is Yadapted to be` secured to shaft I4 by suitable means such asset screw 2| which coacts with a key which fits between the keyways I'I and I8 for positively locking the cardioid shaped cam 20 with respect to the rotatable shaft I4. The cardioid shapedcam shown at 20 is adapted to drive a cam drivericar which I have indicated atV 23 through the Vagency of a pair of cam followers or rollers indicated at 22. There is a longitudinallylextending 'central slot 24 in the camdriven car 23 through which the shaft I4 and the surrounding hub I9 of the cardioid shaped camY 20"extends.AV I provide a pair of laligned U- shaped tracks 25 which are secured to the under side of the base I and have their side fianges depending'downwardly 'to provide a pair of rail guides for theV rollers 26 and the upper side of the cam driven car-23. That is to say, the rollers 26 engage' within the U shaped tracks 25 so thatV the cam driven car 23 is adapted to be reciprocated'longitudinally of the base I as the cam 20 rotates and engages the cam follower rollers 22. It-will be observed that one of the rollers 25 is directly above one of the Vdepending rollers 22 driven by the cardioid shaped cam 20. The other roller 26 'is-located adjacent the opposite end of the Ycam driven car 23 and serves to maintain the cam .driven car in a predetermined path asV the cardioid shaped cam 20 rotates. In order to assure the 'precision movement of the cam driven car 23, I provide a pair cf track'members on opposite sides of the'cam driven car 23. A relatively long track memberis shown at 21 which is a substantially ZV type track for the line guide carriage at the long side of the line guide carriage. I provide aV relatively shorter track 28 of the same ZV type section for the shorter side of theV line guide carriage;Y The

rails

21 and 28 are secured tothe base I by suitable means such as securing screws with attached nuts indicated at 21a and 28a' passing through the base lI for securing'the rails 2l and-28 tothe under side of the basev I. The carriage 23 is provided with rollersZS` on the longer side'thereofengaging railY 2'I VandV rollerV 30 on the opposite'side thereof engaging rail 28. f The line guide which is reciprocated by the line guide carriage 33 is driven by suitable 'attachment'mean's indicated at 3I which extend through the base I passing through the longitudinally extending slot shown at 32.

The slot 32 extends along base I for the entire length of the reciprocating path of the line guide which I have'shown at 33. The line guide 33 will be more clearly understood by reference to FigsSZ, 3,"and10-14. Line guide carriage 33 carries Yextension lugs' 33a. thereon which are adapted to` be engaged with respect to the upwardly extending attachment means 3I projecting upwardlyrthrough base I from the line guide carriage 33. "The extension means 33a connect aiscgocs' projecting laterally therefrom and'on which the' line tensioning device 35 is mounted. The line tensioningdevice 35 is made up of two coacting membersY 35a and 35h which are pressed into continuous engagement to form a pulley around whichl the line is directed. The parts 35a and 35h are pressed into engagement by the soil spring 36, the tension on which is adjusted by means of adjustable screw 31 engaging screw threads on the stud 34. The line guide 33 also carries an eye 38 for guiding the line before it enters, and an eye 39 for guiding the line after it leaves the tensioning'pulley 35. There is a line guide slot 4I! in .the line guide carriage 33. A packing roller engaging means' and line guide shown at 4l is carried bythe upper extremity of the line guide carriage 33 for continuously guiding the line and engaging the line on the line storage roller during the operation of the rewinding mechanism.

t The lline storage roller is shown at 42 and as illustrated more particularly in Fig. 18, there is t an end slot 42e therein in which the endof the rope may be engaged before the coiling operationV is commenced. The line storage roller 42 Vhas the vopposite ends thereof recessed as shown more particularly in Fig. 16 from which it will be seen that there is an endrecess 42a in one end and a slot and recessV 42h in the other end of the roller 42. It will be observed that recess 42a is substantially clindrical whereas recess 42D is substantiallyv cylindrical with a radially extending slot on either side for engagement by the driving spindle head shown Aat 41. TheY standard I@ as shown more particularly in Figs. 15 and 16 carries a locking head 43 thereon which includes a locking slot 44 and a semicircular recess 45. A winding key 45 extends through the axial bore through the locking head 43. The winding key 4B includes a handle grip shown at 46c and illustrated more particularly in Fig. 20, anda pin 46h substantially midway of the `length thereofl and an end flange 46c which allows the end of the winding key to extend into the recess 42d in the'storage roller 42. l

` As heretofore pointed out, the driving spindle head 41 engages the slot 42h in storage roller 41 for driving the storage roller 42 about the recess 42a and the projecting end of the winding key 46 as illustrated in Fig. 16. The driving spindle head 41 is operated by the driving spindle shaft Shown at 48. The driving spindle shaft 43 is mounted in journals 49 and 5I! in the triple standard Il. There is a pin 42a in the end of driving spindle shaft 48 which is adapted to be engaged with the socket of a driving crank 52. The socket of the driving crank 52 is slotted as indicated at 53 for vengaging the ends of the pin 48a and Vallowing the driving spindle shaft to be rotated to impart rotary movement to the driving spindlehead 41 for correspondingly driving 3I and laterally with respect to the -ing shaft and isv adapted to mesh with the bevel gear l5 heretofore described. Rotary motion imparted to crank 52 is accordingly transmitted both to the line'storage roller 42 and to the cardioid 'shaped cam 2d which in turn moves the cam driven car 23' through cam followers 22 for imparting movement to the line guide carriage 33 which in turn feeds the rope or line 56 upon the mandrel orlinel storage roller 42. The movement of the lineV guide carriage 33 is originally set so that the line guide carriage reciprocates as the line is fed from one end of the coil to the other end thereof. The coil is built up on the line storage roller 42 in the shape illustrated more particularly inv Figs. 21 and 22. The line is rewound rapidly vupon the storage roller 42. It may be desirable to remove the coil 51 from the storage roller 42 in which event the storage roller is projected through the aperture 3 in base I as illustrated in Fig. 21 with the end of the coil 51 restheavier line must be handled and in such cases l provide a larger and heavier construction of rewinding machine. As illustrative of the larger `machine, reference is made to Figs.`2333.

`The base of the larger machine is indicated at 60 mounted upon suitable channel beams which greatly strengthen the base structure.V The construction ofthe large size rewinding machine is with two major exceptionssubstantially the same as that of the smaller rewinding machine. The two machines have different constructions of line guides. In the larger machine, there is a multi-- plied drive for the line guide carriage. This multiplieddriv'e makes it possible to use the same size cam in the `large machine as is used in the smaller machine to obtain the much longer axial length'of winding Vrequired on the larger size machine. 'I'hat is to say, the same tools maybe employed for constructing thereciprocatory driving mechanism in both machines and yet a sturdier and a longer path drive obtained in the larger sizemachine by means of the mechanism hereinafter explained.

I provide a standard 6I adjacent one end of the base 62. There is'a bearing 62 in the head of the standard 6I throughV which the winding key 63 extends. The winding key 63 as shown' more particularly in Fig. 24 has a flange 63C thereon which limits the distance into which the end of the winding key projects into the recess 64a in the end of the Vline storage roller 64. The recess 64a is substantially cylindrical in shape and receives the end of thel winding key 63.

'Ihe driving head 65 which imparts movement to the mandrel or spindle 64 is driven by the driving spindle shaft shown at 1I which is journaled in substantially the same manner as is the driving spindle shaft 48 in the form of my invention heretofore described. In the larger ysize machine, however, the supporting parts and bearings are substantially larger and more rugged. I have shown. at 12 the triple standard which provides

bearings

13 and 14 for the driving spindle shaft 1I. The shaft 1I is driven through the crank 15 which may be connected with the driving spindle shaft 1I when required. The central -portion of the standard 'I2 provides a bearing for the central shaft which is the equivalent of shaft I4 in the earlier form of myfinvention and in the modied form thereof. The shaft I4 carries the bevel gear I5V which meshes with theV cating cam driven car has been shown at 85' mounted in much the same manner as the car 23 in the previous form of my invention. The car 68 is provided with a pair of follower rollers 22 which engage the cam 20 and allow the reciprocatory car 68 to be shifted back and forth. On the upper surface of the car 68, I mount rollers 26 which engage the depending channel shaped members 25 in order to guide the cam driven car in its reciprocatory path. Because of the heavy construction of' car 96, I increase the number of guide rollers 29 as indicated in the drawings in this form of my invention. The sidewalls of the car 88 are bent upwardly vand serve to carry the

roller members

91 and 68. The

roller members

67 and 88 operate in the Z shaped rails 89 and le secured to the under side of the base support shown at 68. The cam driven car 66 is thus free to be driven in a reciprocatory path back and forth in order to operate the rope guide means as hereinafter more fully described.

rihe cam driven car 86 carries a rack member l? on one side thereof as shown more clearly in Fig. 26. The rack "Il engages a pinion 18 carried on the same hub or shaft as is the larger gear 'i9 which is driven simultaneously with the movement of the pinion 78. The pinion 'i8 and gear "I9 are mounted on a hub which is journaled or ivoted about ,a stub shaft 80 which is carried by 1 the frame 8i serving as a journal forthe shaft 80.

The gear 'I9 meshes with an extended rack 83 which connects at one end with the drive 82 for the line guide carriage. The rack 83 is maintained in engagement with the gear 'I9 by the action of roller 88 operating againsttthe rear of rack 83 as the rack 83 reciprocates. The drive S2 for the line guide carriage is operated in a reciprocatory path under control of the guide rails 86 and 8l secured to the frame structure 99.`

Thedrive 82 carries a set of

rollers

84 and 85 which engage the guide rails 86'and 8'! for allowing the guide 82 to be driven in a reciprocatory path. VThere is a slot 90 in the base structure tifs through which lugs 9| on the driver82 project. 'I'he lugs 9| are apertured at 9|a to allow a pin 92 to extend therethrough and serve as a connecting means for the lugs 94 on the'body of the line guide carriage V93 shown more particularly in Figs. Y28 and 29.

The line guide-carriage 93 is provided with a tension spring adjusting screw shown at 96. The screw 99 is provided with a swivel head 91 whichbears against the roller of the line guide carriage 93 and allows the member 96 to rock to various angular positions in order that the body structure 9S of the line tensioning device may shift to various positions. The member 96 is provided with a tension spring 99 which bears against the body structure 98 of the line tension-ing device. An adjusting screw is adaptedto be'adjusted with respect to spring 99 for predetermining the Aspring pressure exerted against the body structure 98 and accordingly mandrel or spindle 64., Ihe line guide carriage Vroller shown at I I2.

which I have designated by aVV similar numberi 93 is provided withV outstandingA lug members ISI adjacent the top thereof which serve as a hinge for the body structure 98 of the line tensioning device. A pin |02 extends through the body structure 98 and the lugs I0| for hingedly supporting the body structure 9B with respect to the line guide carriage 93. The line guide carriage 93 is also provided' with-'rearwardly extending lugs Vor projections |04 which serve as a pivot means for the line tracking The line tracking roller I I2 is secured between the projection members |04 by means of the removable line tracking roller spindle |05.

The line guide carriage 93 carries a line guide member and a pair of line guide members Iii'i for directing the line |88 under the first of the guide rollers |93. The line extends between the guide rollers shown at |03. That is to say, the line |89 extends'under the lower roller |03 and over the upper roller |83 carried by the bodyV structure '98 of the line tensioning device and then extends underA the line tracking roller ||2 from which the line is distributed to the coil shown at |09. The rope is rewound on the mandrel or spindle Yell into a coil |09 in the same manner as heretofore described'. When the rope is rewound on the mandrel or spindle, it may be removed as a complete coil as heretofore-described in connection with Fig. 21 and Fig. 22. It will be observed that the line tracking roller 52 is relatively wide. There is no central groove in the line tracking roller I2 soV that the rope is ermitted to change in Vits angular position as the rope is supplied to the coil on the mandrel or spindle. That is tosay, the rope may assume various angular positions as the rewinding voperation proceeds. The rewinding isY generally conducted at relatively high speeds and it is possible to restore the mandrel within a very brief interval even when the rope-is of very long length such as lengths of 2100 feet. I have accomplished such rewinding of relatively heavy rope of Vlengths, of 2100 feet in such intervals of time as seven minutes which is an accomplishment which greatly facilitates the use of the rewinding apparatus with line Ythrowing equipment in lifesaving operations.

As in the earlier form of my construction, I`

provide a protective plate beneath the moving mechanism. I have shown the plate atr IIO secured by suitable means I I I to the under surface of the supporting frame 60.

The tandem multiplying gears 'F8-I9 are arranged one above the other on a common hub. The smaller of these twogears, that is, '18, engages the short rack 'il attached to the cam driven car (5E. The larger gear 19 engages the long rack 83 attached to the line guide carriage 93. The throw ofthe cam is transmitted to the multiplying gears by the short gear rack The throw of the cam is multiplied and reversed in these gears as the motion is transmitted to the long gear rack 83 and line-guide carriage 93. The multiplying factor of these gears is equal to the ratio of the larger to the smaller of their pitch diameters.

By virtue of the ilat construction of the cardioid shaped cam 20 and the compactness of the parts associated therewith, the base of the machine is of relatively low height. The operation of the reciprocatory mechanism is such that for continuous driving of the storage roller, reciprocation ofthe line guide is effected, automatically reversing as the end of the coil is reached.

I intend no limitations upon my invention other than may be imposed by the scope of lthe appended claims.
