DECK-TRAVELER.

Application filed September 17, 1907. Serial No. 393,346. p

To all whom it may concern:

'Be it known that I, HENRY P. THORN, a subject of the King of England, and resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Deck-Travelers, of which the following is a specification.

On yachts and other sailing vessels it is customary to fasten to the deck or other support a bar upon which the eye or ring of the lock of the main sheet or rope may slide back andforth as the vessel tacks or comes about, but. with that construction .when the main sail jibes and the block' sis-thereby carried quickly and forcibly across the rod or traveler` there is danger of springing or breaking the boom or main sheet and otherwise endangering the vessel, because of the sudden stoppage of the blockat the end of the bar. The object of my invention is to provide a traveler that will ypermit the blockof the main sheet or other rope to slide or travel across the deck with resistance to obviate the shock incident to thel swin ing of the boom during jibing, to reduce-t e strain on the parts and aid in 'preventing the breaking or ending of the boom or the breaking of the main sheet or rope.

In carrying out my invention I provide al pair of cylinders located in line or opposed and secured upon the vessel deckor ,otherl suitable support, and I locate pistons or plungers Within said cylinders With a passage or bore vwithin said pistons communicating with said cylinders, and to said pistons I attach a block of the main sheetor rope, and

within said'cylinders and the passage of said kpistons I place asuitable fluid, such as lycerin, which will resist the movement o the pistons in either direction and yet permit the pistons to move gradually the required distance to the limit of their outward move-` ment in the respective cylinders.

My invention also com rises novel details of improvement that will e more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanyin drawings forming part hereof; wherein,

igure 1 is a plan View of-a deck traveler embodying my invention, and Fig. 2 is a central section thereof.

`In the accompanying drawings the numerals l, 2, indicate suitable cylinders shown provided with bases 1, 2, adapted to be attached to a vessel deck or other support, and at 3 is a piston the opposite ends 3a of which enter the opposed cylinders, and are adapted to'slide back and forth therein, all so arranged that when one piston end is at the outer end of one cylinder the other piston end will be near the inner end of the opposite cylinder, and vice versa. The bore 3b of said piston communicates with both cylinders. Suitable nuts 4 and packing 5 close the inner ends of the cylinders to keep tight joints as the pistons slide. At 6' is a screw fitted to tube 3 and adapted to pass across bore 3b to regulate the freedom of. flow of fluid through sald bore, and said screw may enter a socket 6, or fit firmly against the wall of the bore, to prevent the flow of any fluid therethrough. To the piston 3 is to be attached a block of the main sheet or other rope of a vessel, and for this purpose I have shown said vpiston provided with an eye 7 to receive the eye or ring-of the block. -Atthe outer-endsof the cylinders Ihave shown caps 8 screwed thereon and provided with tapering plugs 9 shown extended into the cylinders and having threads or screws 9a, which plugs are adapted to enter the ends of bore 3b to control the flow'of fluid through such bore,and by adj us ting such plugs lengthwise of the cylinders the flow of fluid into bore 3b may be regulated as desired. With my improvements fastened upon the 1 Y deck or ot er part of a vessel, and the cylinders and bore 3b of piston 3 filled with a suitable fluid, such as glycerin, and a block of a main sheet or rope attached to veye '7, the pressure from the sail attached to said block will cause the pistons to -move toward the adjacent or corresponding cylinder, whereupon fluid will be pressed out of such cylinder through bore 3 into the opposite c linder, and each time that the block is shifted from one side of the deck to the other the pistons will slide in their c linders and'be resisted by the fluid in tile cylinder 4toward which the pistons slide until such fluid has passed through bore 3b into the opposite cylmder. vIf the boom shouldswing suddenly from one side of the vessel to'the other, as when the sail jibes, the sudden strain on the block caused by the jibingwill be cushioned or `resisted by the pressure of the corres' ending piston against the fluid in its cyliner which will thereby be forced through 3l" into the other cylinder and ease the shock from the jibing. As the piston reaches the plug 9 the freedom of flow of fluid Jfrom the I cylinder Awill be decreased gradually and thereby check the shock of the piston coming forcibly against the cap 8, lor its int-erposed packing 10. v

Changes may be made in the details of arrangement shownand described without departing from the scope of the appended claims.

Having I claim-is: v

1. A deck traveler comprising a plurality of opposed cylinders, a piston the o posite ends of which are located in said cy mders and provided with a passage communicating with said cylinders, and means for connecting the piston with a rope.

2. A deck traveler comprising 'a pair of opposed cylinders, a iston the opposite ends of which are located in said cylinders, and spaced apart a distance less than the disnow described` my invention what tance between ythe outer ends of said cylinders, andv rovided with a passage communicating wit said cylinders, and 4means to connect saidv piston with a rope. p 3. A deck traveler comprising a pair of opposed cylinders, a piston-havin opposite ends entering said cylinders, an having a bore communicating with said tylinders, means to connect said piston with a rope, and means to control the flow of fluid through said bore. 4. A deck traveler comprising a pair of opposed cylinders, a piston having opposite ends entering said cylinders and having a bore communicating with said cylinders, and means to connect said piston with a rope, means to control the flow of fluid through said bore, and a screw carried by said piston adapted to be adjusted across said bore to regulate the flow .of fluid therethrough.

5. A deck traveler comprising a pair of opposed cylinders, a piston the op osite ends of which are located in said cylin ers, and provided with a passage communicating with said cylinders, and means at the outer ends of s aid cylinders to reduce the flow of fluid through said passage as the corresponding piston end approaches the outer end of its cylinder.

6. A deck traveler, comprising a pair of opposed cylinders, a .piston 4the opposite ends of which are located in said-cylinders and provided with a passagei communicating with said cylinders, and plugs at the outer ends of the cylindersada'pted to enter said passage t0 reduce the flow of iluid therethrough as the corresponding piston end approaches thc outer end of its cylinder.

7. A deck traveler comprising a pair of opposed cylinders, a piston the outer ends of which are located in said cylinders and provided with a .passage communicating with said cylinders, taper plu s at the outer ends of the cylinders adapte( to enter said passage to reduce the flow of fluid therethrough as the corres ending piston end approaches the vouter en of its cylinder, and means for adjustin said plugs 1n the direction of the axes ol t ie cylinders.
