Application filed February 9, 1905. Serial No. 244,977.

To all whom it may concern:

Be it known that I, ANGUS MoNEIL, a subject of the King of England, residing at North Sydney, county of Cape Breton, Province of Nova Scotia, Dominion of Canada, have invented certain new and useful Improvements in Draft Appliance; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in draft appliance adapted particularly for use in towing vessels, and comprises certain features of novelty in the detail construction and arrangement of the cooperating parts whereby a single unitary structure is produced which is strong, durable, and economical and which will respond to all the requirements of a device of this sort in practical use.

In towing vessels it is well known that the tow-line at times becomes slack and again is tightened up very rapidly, because of which breaks frequently occur in the tow-line, especially where wire ropes or cables are used, and it has been found that by attaching one or more of the devices shown in the accompanying drawings that such breakage in the towing-line will be positively avoided.

In the annexed drawings similar numerals of reference indicate corresponding parts in all the views, wherein Figure 1 is an elevational view of my improved draft appliance. Fig. 2 is a longitudinal sectional view thereof, and Fig. 3 is a detached end view of a modification adapted to be used in place of the hook shown at the upper end of the device illustrated in Figs. 1 and 2.

Referring to the drawings, 1 indicates a barrel or outer shell of metal tubing, preferably formed as a straight cylinder from end to end. Within one end of this cylinder is seated a plug 2, having the offset or shoulder 3 and being providedwith a perforation extending therethrough in line with the longitudinal axis of the barrel 1. Within the cylinder 1 and projected through the plug 2 is a draft-rod 4, which is provided at one end, preferably, with a loop or eyelet 5, by means of which it may be connected with a cable or with any convenient place of attachment for use in towing.

Supported upon the rod 4 is a disk 6, which is held on the inner end thereof, while a spring 7 rests against the plug 2 at one end and presses upon said disk 7 at its opposite end. The rod 4 is preferably screw-threaded at its inner end, and on the screw-threaded portion is secured a nut 8, made fast against rotation on the rod 4: by means of the pin 9, (shown in Fig. 2,) the said spring and nut serving to hold the disk 6 in position upon the rod 4 and the shoulder 3 serving to seat the plug 2 within the cylinder or barrel 1. In addition to the shoulder 3 the said plug is preferably brazed within the cylinder 1, whereby a positive connection between the said parts is thereby established.

At the opposite end of the tube 1 is inserted a plug 10, having a shoulder 11, as shown in the sectional view in Fig. 1, abutting against theend of the tube 1, while a pin or bolt 12 is projected through the said tube and plug for the purpose of connecting the same together. Connected pivotally to the plug 10 is a hook 13, which issupported upon the pivot 14in said plug, the inclined faces of the

members

10 and 13 abutting substantially within the loop 15, surrounding the said parts, which loop is held in an upward position by means of the small flat spring 16, whereby if it is desired to throw off the hook 13 all that is necessary is to depress the loop 15 against the influence of the spring 16, so as to cause it to clear the nose 17 of the said member 13, whereupon the book 13 may be swung backwardly upon its pivot. It will be observed that perforations 18 are provided in the tube 1, through which oil may be admitted to the interior of the tube for the purpose of lubrication, this being found desirable in a structure of this class. Instead of the hook 13 it may be found desirable to substitute a loop 13, integral with a plug 10, as shown in Fig. 3 of the drawings, and it will be understood that this modification is within the spirit of my invention. In practice cables are connected, respectively. with the

loops

5 and 13 or with loops 5 and hooks '13, or the parts may be connected in any desired fixed members attached to or upon the vessel and a cable connected to the opposite end of the device, whereupon draft applied to the cable will be first received by the draft-rod 4 and communicated through the spring 7, whereby tension will be applied to said spring and the jerking strains incident to towing will be minimized or wholly avoided. V

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of tube, shouldered plugs therein at each end,

one of said plugs being permanently connected to said tube and having a longitudinallyprojected opening therein, a draft-rod projected through said opening, a loop or eyelet on the end of said rod, a spring upon said rod extending longitudinally of said tube, a disk upon said rod beyond said spring, a securing nut and pin upon said rod and beyond said disk, a pivotally-supported engaging hook connected with one of said plugs, and a springsupported loop surrounding one portion thereof.

2. In a draft appliance, a tube, a plug secured therein at each end, said plugs being provided with shoulders abutting against the ends of said tube, in combination with a draftbar projected through one of said plugs and extending longitudinally within said tube, a spring upon said draft-bar, a disk on said bar beyond said spring, means for securing said disk in position, an integral loop on said draftbar, an engaging means extending longitudinally from and pivoted to the plug at the end of the device opposite said loop, and means for locking said engaging means in position.

3. 1n a device of the character described, a

' said disk and said plug, in combination with a plug at the opposite end of said tube, a rockable hook mounted on said plug, and a loop adapted to lock said hook in position.

4. In a device of the character described, a tube, plugs therein, one of which is perforated longitudinally of said tube, a longitudinallyslidable draft-rod, a spring thereon, means for holding said spring upon said rod, an integral loop on said rod, a pivotally-supported draft-hook connected with the opposite end of the device, and a rockable loop adapted to lock said hook.

5. In a device of the character described, a tube, a plug in one end with an opening therethrough, a slidable draft bar extending through said opening into said tube, a spring thereon, a disk connected with the opposite end of said draft-rod, a removable plug in the end of said tube in proximity to said disk, a pivoted hook on said removable plug, and a yielding engaging member adapted to retain said hook in a locked position.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

ANGUS MoNEIL.
