which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in methods of and apparatuses for steering tows of cargo boats. In many waters of this country, and more especially, on the rivers in the central and western parts, a very common mode of trans= porting bulky materials, such as coal, oil, ore or lumber, is by means of tows composed of many flat boats, and pushed by one or more steamers, usually of the stern-Wheel variety. The flat boats employed are of a generalrectangular shape, and are so secured together as to make one homogeneous mass, with the pushing steamer placed within a recess or opening at the after part of the tow, made by the omission of one or more flat boats; thereby making the entire towin every waylike asingle large boat. One of the greatest difficulties in this method of transportation, lies in the inability to properly steer the tow, as for instance when approaching a sharp bend or curve in the river. This inability arises partially from the position of the towing steamer, which is secured at one extremity of the tow, and partiallyfrom the small size of the steamer as compared with the size of the tow. By means of this inadequacy in steering the tow, its size is reduced, to limit this objection, to a point far below that which could be economically pushed by the steamer, as the tow has to be kept at a certain minimum width, owing to the narrowness of the rivers, and is necessarily kept at a reduced length, to enable it to be readily maneuvered.

It is the object of our invention to do away with these objections, and by our invention tows can be very much lengthened and at the same time be more readily steered and maneuvered than heretofore.

Serial No. 417.074. (N0 model.)

Our invention consists generally in the employment of suitable rudders or other steering devices, at the forward part of the tow, to be operated and directed from the pushing steamer placed at the rear of the tow.

In order to better comprehend the nature of our invention, attention is called to the accompanying drawings, in which- Figure 1, is a view of one of the steering rudders in position. Fig. 2, is a plan view of the rudders and controlling devices; and Fig. 3, is a top view of the tow,showing our device in operation.

In all of the several views like parts are designated by identical letters of reference.

On the outside of each of the leading out side boats of the tow, and as far forward as conveniently possible is mounted a rudder, a. This rudder a, is rectangular in form and is preferably of the balance type as shown in the'drawings, but it can be made in the form of an ordinary rudder. This rudder is mounted upon the stock or spindle b, which is in turn rotatably mounted upon a support a, passing completely across the boat and which is secured to the two gunwales d and e, by means of the pivot to, and the pin t. The rudder stock, passes up through the bearing on the outer end of the horizontal support 0, and is secured thereto. In order to allow the rudder to be worked in different depths of water and with boats of different drafts the rudder is mounted as shown in Fig. 1. The spindle b, of the rudder passes through the bearingf, and is capable of moving freely up and down therein. A ring or similar device g, encircles the rudder stock above the bearing f. This ring is secured to the stock by means of the pin or similar deviceh. As the ring g, is of larger diameter than the bearing f, the rudder will be supported by means of the aforesaid ring, but will be free to rise upon meeting with any obstruction. By placing the ring upon different parts of the stock b, the rudder a, will be adapted to different depths of water and dif- 5 ferent drafts of boats. Rigidly secured to the upper extremity of the rudder stock I), and parallel with the rudder a, is a tiller or yoke 11, to the extremities of which are secured suitable controlling ropes or chains j, lo, l, m, the

ropes j and 70 leading from the port or left rudder, and the ropes Z and on leading from the starboard or right rudder. These ropes pass through suitable pulleys or blocks at, 0, p and q, secured to the center of the forward part of the tow, and from thence lead aft to the pushing steamer. The lines j and m are connected together after passing through the blocks 0 and n, and form the controlling rope a, while the lines 7t and Z, after passing through blocks q and 19, form the line .9. Both lines r and 3, continue back to the pilot house or other convenient point on the steamer, or any place on the tow, where they are attached to a suitable steering wheel, tiller or steam windlass or capstan, where they can be readily and quickly handled. It will be seen that upon pulling the line 0', and slacking the line s,the rudders will be turned in the direction of the arrows, and the tows head will be turned to the right. The opposite effect will ensue, upon hauling upon the line .9, and slacking upon the line a". When it is not desired to use these rudders, as for instance when loading the tow, the pin 25, on the outer end of the standard 0, is removed, thus allowing the standard to move backward revolving upon the pivot u, and allowing the rudder a, to lie against the side of the boat out of the way.

We have described our invention as applied to tows that are pushed by a steamer; but it can be as well used in connection with a towing steamer in which latter case the rudders would be situated upon the after end of the tow.

We have described our invention as applied to tows composed of a number of flat boats with a towing steamer in the rear thereof, but it may as well be applied to tows of other boats, such as canal boats, or to a single large boat, or to rafts of logs, and with the steamer upon either side as Well as upon the rear extremity.

Having now described our invention, what we claim as new therein is as follows:

1. An improved device for steering tows consisting of a rudder placed on each side of the forward part of the tow, and outside thereof in combination with suitable controlling mechanism for controlling said rudders. consisting of ropes extending to and operated from the towing steamer at the rear of the tow.

2. An improved device for steering tows consisting of a rudder mounted upon each side of the forward part of the tow, and outside thereof suitable tillers or yokes rigidly secured to the aforesaid rudders and controlling ropes, substantially as described, leading to the rear of the tow, and so arranged that both rudders will simultaneously partake of the same movement.

3. An improved device for steering tows consisting of two rudders a, mounted at each side of the front of the tow, a tiller or yoket' for each rudder, the ropes Z and 70 leading from opposite ends of opposite rudders and passing through suitable blocks and verging into the controlling ropes and the ropesj and m connecting with opposite ends of opposite rudders, passing through suitable blocks and connecting with the controlling rope 0*, said controlling ropes extending to the steamer, and the mechanism upon the steamer for operating said ropes whereby the rudders will be moved simultaneously in one direction or the other.
