ROWLOCK.

SPECIFICATION forming part of Letters Patent No. 555,747, dated March 3, 1896.

Application filed January 2, 1896. Serial No. 574,032. (No model.)

To ctZZ whom, it may concern:

Be it known that I, OLE O. STORLE, of Burlington, in the county of Racine and State of \Visconsin, have invented certain new and useful Improvements in Rowlocks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main object of my invention is to provide a strong durable easy-working rowlock that will not get out of order and can be conveniently applied to boats and ears, and generally to improve the construction and operation of devices of this class.

It consists of certain novel features in the construction and arrangement of component parts of the rowlock as hereinafter particularly described and pointed out in the claims.

I11 the accompanying drawings like letters designate the same parts in both figures.

Figure 1 is an outside elevation of my inproved rowlock, the ear in connection therewith being shown in cross-section, and parts of the rowlock being broken away; and Fig. 2 is a rear elevation viewed from the right with reference to Fig. 1, the car being removed.

A designates a cylindrical pin which may be conveniently cast with or secured in a stand having angular feet a a for attachment to the gunwale of a boat.

B is a sleeve fitted to turn freely upon the pin A, and formed at its upper end with a transverse fulcrum-bearing Z), which ter1ninates at one end in a downwardly-turned hook Z). It is also formed on one side opposite the hook Z) with a bearing plate or surface 0 parallel with its axis.

O is an angular-sh aped casting that may be designated a saddle, adapted to rock upon the horiZontally-disposed fulcrum-bearing Z). It is open on the under side except at one end, which is formed with a ring or loop 0, adapted to pass loosely over the hook Z) and encircle the projecting end of said bearing, which is made cylindrical at that point. At the opposite end and on opposite sides thereof said saddle is formed with seats 0 c for the attachment of an oar, as shown in Fig. 1. These seats are made concave or otherwise shaped to fit the oar, which may be screwed, bolted, riveted or otherwise secured thereto. They are located a little below the saddle-bearing, and are connected by a segmental or are shaped guide-plate c which is adapted to slide upon the plate or surface b and. thus hold the saddle from slipping endwise on its bearing Z). The pin A projects at its upper end into an opening between the upper end of sleeve B and the transverse fulcrum-bearing Z), and is secured in said sleeve by a severed ring a, which may be made of wire and sprung or bent into a circumferential groove formed in the upper end of said pin. The upper end of the pin A is preferably made to bear against the under side of the transverse bearing-bar Z), and to hold the lower end of sleeve I5 clear of the shoulder at the base of said pin. The weight of the ear and its saddle is thus carried upon the end of the pivotpin, wear is avoided and the turning of sleeve Bis facilitated.

In operation the oarsman sits to the left of the rowlock, as'shown in Fig. 1, so as to pull, when the oars are in the water, against the bearing plate or surface b on the rear side of sleeve 15 and pivot-pin A. The oar rocks or swings vertically with its saddle (l on the horizontally-disposed f ulcrum-bearing Z), and at the same time turns horizontally with said bearing and the sleeve B on the verticallydisposed pivot-pin A. To feather the oars they may be turned upwardly, the saddles G pivoting at their front ends on the overhanging portions of the bearings Z), encircled by the rings 0; but ordinarily the guide-plates 0 will bear against the plates Z)*. The cars are easily detached and removed from the boat by turning them upwardly and forwardly so as to carry the guide-plates 0 over and clear of the bearings Z) and disengage the rings 0 from the depending hooks Z).

Various changes in the minor details of the device may be made within the spirit and intended scope of my invention.

I claim 1. In a rowlock the combination of a pin adapted to be secured in a vertical position to a boat, a sleeve adapted to turn on said pin and provided transversely to its axis with a fulcrum-bearing, a saddle adapted to be secured to an oar and to rock vertically upon said bearing and to turn horizontally therewith on said pin, substantially as and for the purposes set forth.

2. In a rowlock the combination of a pin adapted to be secured in a vertical position to a boat, a sleeve adapted to turn freely on said pin and provided transversely to its aXis with a fulcrum-bearing and on one side With a vertically-disposed bearing, and a saddle adapted to be attached to an oar and to rock vertically upon said fulcrum-bearing and provided with a guide arranged to loosely engage said vertically-disposed bearing, substantially as and for the purposes set forth.

In a roWlock the combination of a pin adapted to be secured to a boat, a sleeve fitted to turn thereon and having a transverse fulcrum-bearing terminating at one end in an overhanging hook, and a saddle adapted to be attached to an oar and to rock on said bearing and formed at one end with a ring or loop loosely fitting over the hooked portion of said bearing, substantially as and for the purposes set forth.

4. In a rowlock the combination of a pivotpin for attachment to a boat, formed with a circumferential groove at or near one end, a sleeve fitted to turn 011 said pin and having a transverse fulcrum-bearing at one end, a

severed ring seated in the groove in said pin for holding the sleeve thereon, and a saddle adapted to be attached to an oar and to rock upon said fulcrum-bearing, substantially as and for the purposes set forth.

5. In a rowlock the combination of a pivotpin for attachment to a boat, a sleeve fitted to turn thereon, and having a transverse fulcrum-bearing at one end and a bearing-surface on one side parallel With its axis, and a saddle adapted to rock upon said bearing and formed with a ring or loop fitting loosely over a projecting end of said fulcrum-bearing, a seat for attachment to an oar and a guideplate adapted to bear loosely against the bearing-surface on said sleeve, substantially as and for the purposes set forth.

0. In a rowlock the combination with a pivot-pin having a base for attachment to a boat, a sleeve fitted to turn on said pin and having a transverse bearing which pivots upon the upper end of said pin, and a saddle adapted for attachment to an oar and to rock upon said bearing and turn therewith on said pin, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

OLE O. STORLE.
