TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. S. BARNES, of Nebraska City, in the county of Otoe, and State of Nebraska, have made certain new and useful Improvements in Propelling-Apparatus for vessels and other purposes; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention has two general features, the first of which relates to a. device for transmitting reciprocating motion, and the other to a device for feathering the paddles, the latter being susceptible of a reversing-attachment.

To enable those skilled in the art to make and use my improved apparatus, I will proceed to describe its construction and operation.

Figure 1, of the drawings, is a general plan of the apparatus. This view being designed more especially to illustrate the general features of the invention, the reversing-apparatus is not shown.

Figure 2 is an enlarged elevation of one end of the propelling-machine, showing the feathering-apparatus in detail.

Figure 3 is a top plan of the same parts shown in fig. 2.

Figure 4 isa rear elevation of the same parts shown in iigs. 2 and 3.

A and A are two sliding ways, one of which may be attached to the side of the hull of a vessel, and the other may be secured to the out-riggers, as in the case of a bridge-tree. On each end of these sliding ways are placed sliding` heads, B B, the inner faces of these sliding heads being cogged, for the reception ofthe cogs ofthe sectors C, and to these cogged sectors are attached the paddles, D. The two sliding heads are connected together by means of the reciprocating `jointed connecting-rods or barsD. These rods or bars are formed of short pieces, d, which are united in pairs by means of the' central pins di, and the several pairs of them are connected together by means of the outer pins d2. About midway of this jointed connecting-rod it is secured, by means of a fixed pivot-pin,- cl3, to the transverse bar D?, which is firmly secured to the side-ways AA. The connecting-rod of the engine, or other motive-power, is to be attached to the joint d* by means o f-the bar D3, or by some other suitable attachment. I

The eentral joint d3being fixed, itis evident that, as thejoint-pin d* is moved forward and backward, the sliding heads B B willfbe operated in a reciprocating manner, being alternately dra-wn toward andpushed from the centre-pin cl3. As the paddles D are attached to and moved with the sliding heads B B, as will hereinafter morefu'lly app-ear, and as both of these said sliding heads are drawn toward and pushed from the centre-pin cl3 simultaneously, it is evident that one of the said paddles will be moving forward at thesame time that the other one is moving backward, and, therefore, one of the said paddles will be acting upon the water to propel the vessel forward, while the other paddle is returning in a feathered position for a new hold in the water, as willbe hereinafter more fully described. As is clearly shown in iig. 2, there are two cogged sectors, C C1, attached to the central part of the sliding head B. To the upper one of these sectors, C, the paddle Dis firmly secured. This sector gears into theco'gged rack c, which, as the sliding head is moved forward and backward, as it'nears the end of each stroke, is engaged by the tappcts t" c2 onlthe sliding rod Cz, and thereby the said rack isimoved back, the sector is turned partly l"over, and the paddle D is either feathered or turned down for a hold in the water, as the cased may be. The

sec'tor' C forms a semicircle, and at each end of the stroke it makes a quarter turn, as above described.

The sectorCl forms a. quarter circle, and it is placed directly below the sector C, so that the straight face of the latter may rest on the former, and hol-d it rigidly during the forward motion of the paddle. This sector C1 may be turned over, so as to form a rest for the sector C, on either side, by means of-the cogged rack c3. This rack c3 is attached to the side of the sliding head B by means of the pendants c4, and the spring-hooker5 secure the said rack to the said sliding head at either end, as may be desired for a forward or a backward stroke` of the paddle. The hooks c5 will hold the rack c3 in whichever position they may be placed, until they strike one of the tappets c6 c7 on the rod C3.

This sliding rod and its tappets may be moved to either end, as hereafter described, even while the machinery is under full headway, and the sliding rack will, by comingin contact with the said tappets, be moved in. accordance with the adjustment thereof, and the sector C, and its paddle D, will, in compliance with the said adjustment of' the sector C1, befeathered, either fora forward or a backward stroke.

As isQclearly shown in g. 4, the sliding rods CZ Cshave short cogged sections z8 a9, which are engaged by the cogged sectors E El, which are attached" to the operating-lever E2. This lever may have arope or chain attached to its outer end, and the said rope or chain conducted to. the pilot-house, or other convenient portion of a vessel, where the proper oicer may turn the lever tol either side, at pleasure, and thereby shift'the positions of the rods Cz G3 and their tappets, thereby changing the positions of the sectors C G1, as above described, and setting the paddle D, so as to feather in either direction, for a. forward or a backwardxstroke.

Having described my invention, what I claim, is- Y 1. The cogged'sectos C C1, in combination with the paddle D, when arranged andv operated substantially y as set forth.

2. The combination of the reversing-sectors E El and their operating-bar E2, when acting to operate the bar G3 and rack-c3, for feathering tho paddles at either end of stroke, and reversing the same, substantially as Y set forth.
