JAMES HENRY CLARK, OF MIAMI, FLORIDA.

BITT.

Application led March 9, 1928.

This invention relates to bitts.

An obj ect of the invention is the provision of a simple and eflicient device for application to a boat or wharf whereby a rope or 5 line may be readily secured to the device without the necessity of employing knots or hitches.

A further object of the invention is the provision of a bitt formed of any suitable l metal and having a transverse passage, elliptical in cross section through which a rope, line or bight on the end of a line is inserted and then engaged around the bitt for positively retaining the end of the line or rope l in position, the construction of the bitt being such a nature that the rope or line may be readily connected to the bitt.

This invention will be best understood from a consideration of the following detailed description yin connection with the accompanying drawings; nevertheless it is to be understood that this invention is not confined to the disclosure being susceptible of such changes and modifications as shall define no material departure from the salient features ofv the invention as expressed in the appended claim.

In the drawings Y Figure 1 is a view in perspective of the end of a boat showing my invention applied thereto,

Figure 2 is an enlarged view in elevation of a bitt forming the subject matter of my invention,

Figure 3 is a vertical section of the same,

Figure 4 is a horizontal section taken along the line 4-11 of Fig. 8.

Referring more particularly to the drawings 10 designates the deck of a boat showing a bitt l1 secured thereto. This bitt consists of a body 12 which may be any shape in cross sectional area, but is preferablymade round, and the body may be made of any suitable metal such as steel or cast iron, brass or Monel metal. f

The lower end is provided with aflange 13 projecting laterally from the outer surface of the body and provided with passages 14 through which are inserted bolts 15 for securing the bitt to a deck of a boat, a dock, or to a wharf. The upper or free end of the bitt Serial No. 260,321.

is provided with an annular and laterally projectingflange 16 for a purpose which will be presently explained.

The body is 'provided with a transverse passage 17 which extends entirely through the body and may be of any shape in cross sectional area, but I prefer to have said passage elliptical. The elliptical cross sectional area of the passagel provides for greater strength in the body 12, while giving to the passage awidth of sufficient dimensions to permit the ready insertion of the end or bight 18 of a rope or line 19 which is employed for the purpose of attaching a boat or any kform of vessel to a pier, dock or wharf.

In the use of the device the bitt is secured to the docks or wharfs at the proper points and bitts are also secured at proper points on the deck of a boat. The end of the rope or H' line, as shown in Fig. 2, and which in this instance 1s formed into a bight, is inserted through the passage 17 and the end 20 of the bight is placed over the topf of theV bitt andA permitted to lower untill it rests upon the bight. It will be noted by this simple construction that a rope or line having a bight may be very readily applied to the bitt with a great deal of facility. The upper flange l 16 will aid in maintaining the bight in position on the devicel when the rope or line 19 is permitted to slacken.

As shown at 30, a socket is provided for the reception ofthe lower end of a flag pole. This type of bitt may be employed in small boats.

I claim A bitt comprising a body having an elonl gated transverse passage therethrough, said body having laterally projecting flanges at the opposite ends thereof, one of the flanges being provided with means for attaching the body to a fixed support, the passage being elliptical in cross section, the side walls of the passage presenting substantially eXtensive fiat portions to a rope threaded through the passage, the material Lof the body member at the opposite ends of the passage being rounded wherek the rope engages I,the body member adjacent the opposite ends of the passage.
