'DEVICE FOR MQORING AND WARPING VESSELS.

SPECIFICATION forming part of Letters Patent No. 748,618, dated January 5, 1904. Application filed October 31, 1901. Serial No. 80,702. (No model.)

To all whom it may concern:

I Be it known that I, JOSEPH KIDD, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Devices for Mooring and Warping Vessels; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

On the great lakes steamers have now reached such large dimensions that the old and well-known means for mooring and warping have been found inadequate. These old means consist of manila hawsers handled by capstans, there being usually one of the latter at either end of the vessel, with one or more intermediate thereof. The manila hawsers have been found to be unsatisfactory. One objection is that they must be of such a size as to be very unhandy. Wire rope is now extensively used for this purpose in lieu of the manila, for besides being of smaller diameter it is much lighter, stronger, and, lastin g muchlonger,is cheaper. With the greatlyreduced diameter of the new rope winches are entirely practicable, and accordingly where wire is used they have taken the place of capstans. A Winch is much handier for warping than a capstan, for the reason that in a capstan several turnsof the bight of the rope must be taken around the barrel and the slack portion manually hauled upon, re-

quiring the services of two men usually, while in a winch the inboard end of the rope is permanently secured to the barrel, allthe rope that is hauled in remaining on it, which requires but one man to a winch. The relative advantage is greater when winches are used in pairs or are double, as then one man may control two lines, which would require the services of at least three were capstans used. The usual arrangement is to place the winches along the spar-deck, in the central line thereof, the axes of the barrels being parallel to the keel. Each rope can then lead to either side of the vessel, under the barrel to one side and over the top to the other. At the side of the vessel, but inside of the rail, there is a fair lead of some kind, as a pair of bollards or a chock.

All chocks with which I am familiar are unsatisfactory when used for warping and mooring with wire rope. Something must be used to reduce the friction and to prevent the rope unduly Wearing. If rollers be used for this purpose in the chock, there is too much friction and a consequent loss of power. If sheaves be employed, it has hitherto been found impossible under all conditions to get a clear lead from the barrel to the score, and consequently the rope does not at all times work fairly. Sheaves mounted in a turntable are usually unsuccessful, as the turntable is bulky and heavy, and owing to the method of mounting it will not readily turn to respond to changes in the lead and always maintain a direct pull over the sheaves.

My invention relates to devices to be used with wire rope for mooring and warping.

The improved device consists of a body arranged inside of the rail and exactly abreast of the winch. To the fore and aft ends, respectively, of the body is pivoted a block of peculiar design containing a sheave with a score cut to fit the rope. The pivot of the block is horizontal and passes through ears or lugs cast on the frame. The pivot is designed to be directly opposite the center of the barrel, so that the rope will always lead fairly through the bldck. If the lead changes, so as not to be fairly abreast the device, the block will turn upon its pivot to accommodate itself to the pull and allow the rope to run always clear. As the blocks can pivot only outward, it follows that to allow for both fore and aft leads either two ropes'must be used in the same device, one at either end, or else the line must be unrove and changed to the other block to permit an opposite lead. To allow the rope to be unrove, each block has an enlargement in the mortise above the sheave large enough to permit the eye on the end of the rope to be passed through. The rope may therefore be readily changed from one side of the device to the other or from one block to the corresponding one on the other side of the ship. Where a single barrel-winch is used, the body of the device is made short, so that the two blocks may be close together. Where double winches are used, the body is made longer by insertinga Where a pair of single central extension.

ICO

winches are used, the body is made longer still, the object in varying the length of the body being to have the pivoting-points of the blocks as near as possible to the center of the barrels.

In order to better understand the nature of my invention, attention is called to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side view of a device to be used with a double winch. Fig. 2 is a side View of a device to be used with a single Winch. Fig. 3 is a front View of a chockbody. Fig. 4 is a section taken on the line cc of Fig. 3. Fig. 5 is an enlarged section taken on the line y y of Fig. 4.

Essentially the device consists of a body 1, at either end of which is pivoted a block 2 by means of a horizontal bolt 3. A body is secured to the gunwale on each side immediately abreast the winches, the length of the body being so proportioned that each bolt 3- is opposite the center of its corresponding winch-barrel, so that the rope may lead fairly, irrespective of the location of its outboard end. To permit this, the body 1 is cast to the proper length. In practice the ends of all types may be of uniform design, with a central portion 8 of a length varied to suit the exigencies of the occasion. The opening in the central portion may be used as a fair lead for an additional hawser. Each block may be swung outward upon its pivot to an angle of ninety degrees from the vertical as the lead may vary, and thus the score and mortise will always be parallel with the outboard lead. In Fig. 1 a device to be used in connection With two single winches is illustrated. The body is therefore made long enough to accommodate the lead.

In some locations-as, for instance, amidshipsa single winch can be arranged, and for such the device shown in Fig. 2 may be turned to account.

The details of construction of the device are shown in the drawings. The body 1 is preferably cast in a single piece, with an inside fiange 9 for attachment to the stringerplate and a vertical ofiset 10 to be secured against the inner edge of the gunwale. Each fasteningbolt 3 passes through the lugs 11 11, which are cast integrally with the body. As is shown in Fig. 5, each bolt is preferably provided with a shoulder 12,which will bear against the inner face of the lug and permit the nut 13 being set tightly home without danger of springing the lugs and pinching them against the block.

The blocks, which are shown in greater detail in Figs. 4 and 5, consist each of a solid open-bottomed shell 14 with a mortise 15 cut" therein. This mortise communicates with an opening 16, sufficiently large to permit the passage therethrough of the eye on the outboard end of the rope. The mortise is narrowed at 17, adjacent to the inner periphery of the sheave,t0 prevent the rope accidentally leaving the score. The sheave 18 is pivoted on a pin 19, provided with a shoulder 20 and a nut 21. The latter may be set up tight without danger of springing the shell and pinching the sheave.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a mooring and warping device, the combination of a body portion, a sheave-supporting shell pivoted thereon, a sheave therein, the said shell having a mortise larger than the sheave with an enlarged opening 16 above the mortise, separated therefrom by a slot 17 adjacent to the sheave-score, the said slot being narrower than the width of the sheave.

2. In a mooring and warping device, the combination of a body, lugs thereon, a shellsupporting bolt thereon, a sheave within the shell, the said shell having a mortise larger than the sheave, with an enlarged opening 16 above the mortise separated therefrom by a slot 17 adjacent to the sheave-score, the said slot being narrower than the width of the sheave, substantially as set. forth.

This specification signed and witnessed this 4th day of October, 1901.

JOSEPH KIDD.
