'HAYEs and CHARLEs AUGUSTUS BILLINGS,E

citizens of the United States, and residents of f Wendling, in the county of Mendocino and, State of California, have invented an 'Im-w the following is a specification. 1

Our invention is an attachment .for steam-s boats and other water-craft for use as an aid 1 0r accessory for propelling them up swift streams or rapids, where the usual means of;

propulsion are insuflicient. The invention is also ada ted for-use as the j canals or sluggish and shallow streams.

The invention is hereinafter described in;

In the accompanying drawings, Figure '1 is a side view of our'invention. Fig. 2 is a plan Fig. 3 is a plan view of a portion of the attachment or apparatus, showing a portion of the gearing in a different position from that illustrated in Fig. 2. Fig. 4 is a longitudinal section ofa portlon of'the apparatus. Fig. 5 is a vertical cross-section", on the line 5 5 of Fig. 3. Fig. 6 is a detail; view of a portion of the apparatus. v

An oblong rectangular frame A is in practice secured to thebow of a steamboat or v other water-craft and the same is suitably; braced and strengthened by means of iron? bolts and straps. The portion of the frame c or bearing .B is adapted to slide, the same? having parallel flanges I), (see Fi 5,) which; embrace the adjacent portions of the frame, forming opposite'sides of a slot or space a. 5 To each of the blocks or-bearings B is at-j tached a push bar or pole C, which is inclined in position, as shown in Fig. 1, and whosej lower-end engages the bottom of the streamj or other body of water, it being there pro-g .vided with a spike c to furnish a secure hold. The two 'slide-bearingsB, and with them the res ective push-bars C, are actuated or pro- 1 pel ed simultaneously in opposite directions; by means of a double crank-shaftD and rods 7 E. As shown in Fig. 2, the crank-arms of the shaft D project in diametrically opposite directions. '.,The bearings of said shaft are ini Specification of Letters Patent. Application filed June 12,1905.

; raised blocks or abutments a, that are secured to the main frame A near its inner or rear end. Rotation is imparted 'to the shaft D from a driving-shaft F through the medium-of apinion G, that engages a large spurgear H on shaft D. The shaft F is driven by a "motor or any suitable'means either connected with an engine on the boat or used'independently thereof, as the case may be.

The push-bars C are each made in two parts, which are joined together at a point below the framework A, as indicated at c. The form of joint is practically such as is commonly known as a rule-joint, (see Fig. 6,) the lower portion or member of each pushsponding shoulder on the upper member and the latter being further provided with an extensiojnor lug 0 which bears on the forward side of-the lower member, and when'the two members are alined it lies ina slot or groove in the lower member. A plate-spring c is applied on; the opposite or rear, side of each up er member, and its free end bears on the a' jacent portion of the lower member, as shown in Figs. 1 and'6. The object of these joints isto enable the lower members of the pushbars to bend backward when the slide-bearings B are pushed forward, so as to pass easily over stones, ridges, or other obstructions on the'bottom of the stream. It will now be apparent that if the motor-shaft F be driven the rotation of the crank-shaft D will impart a sliding and reciprocating movement to each of the blocks or bearings B, one advancing asthe other is retracted, and vice versa. Thus one push-bar is carried forward and engages the bottom of the stream, while the other is drawn backward and serves to exert traction for pulling the boat forward.

It will be understood that the push-bars C are always held at a suitable inclinationsay forty-five de rees, as indicated-and-they must obvlousy'be adapted for vertical ad- IOO to slide longitudinally in the block b. The same is provided with a pinion or small gear K, which is adapted to mesh with the gear I, and also with a spur-pinion L, which is similarly adapted for engagement with a rack M, fixed on the side bar of the frame A. As shown in Fig. 2, the pinions K and L are out of engagement with the gear I and rack M, respectively, the shaft J being slid inward for this purpose; but in Fig. 3 the shaft J is shown slid outward or in the opposite direction, and thus the pinions K and L are engaged with the gear I and rack M. The former arrangementto wit, that shown in Fig. 2-is the one required when the attachment is in operation, and that shown in Fig. 3 is the cone required when it is desired to adjust a .push-bar C higher or lower. -When the parts are adjusted as shown in Fig. 3, it will be seen that by moving the bearing B in one direction or the other the shaft J will be rotated by reason of the engagement of its pinion L with the rack M, and consequently the gear I will be rotated, because it is in mesh with the pinion K on said shaft J, and in turn such rotation of the gear I will move the push-bar up or down, according to' the direction of the movementfof the bearing B.

It will now be seen that by causing partial or complete rotation of the crank-shaft D the bearings B may be moved to any extent required to adjust the push-bars as conditions require. For rocking the sliding shaft J in the position shown in Fig. 3, which is requisite during the time the required adjustment of the push-bars is being made, we employ a lever N, which is pivoted upon the stud bfliixed in the side of the block I). (See especially Fig. 3.) The shaft J is suitably engaged with such lever N, and consequently by oscillating the latter in'a horizontal plane the shaft J may be adjusted in one direction or the other to throw it into or out of gear. For locking the lever N in either of the two positions indicated in Figs. 2 and-3 we employ a pivoted drop latch or catch 0, (see Fig. 5,)

' the same having notches for engaging the lever N, as shown. When the lever is adjusted-in the position shown in Fig. 2, or, in other words, in position to slide the shaft J inward, so that its pinions K and L will be out of engagement with the spur-gear I and rack N, its forward end is necessarily thrown inward or close to the adjacent side of the block 1). Such end portion of the lever N is provided with a rectangular opening a, adapted to receive the corresponding polygonal end of the shaft i, upon which the gear I is keyed. Consequently when the lever N is in the position shown in Fig. 2 the polygonal end of the shaft '11 enters the opening n, and the shaft is thereby locked, and consequently the adjacent push-bar is also looked, and, contrariwise, the lever N is thrown into the position indicated in Fig. 3, which is out of engage-' ment with the shaft 'L of gear I, and consequently the latter is free to rotate and the adjacent push-bar is released and free to slide vertically. In brief, by the simple adjustment of the two levers N from right to left, or vice versa, the push-bars C may be locked so as to be immovable while the apparatus is in use or may be unlocked and put in gear with the means for adjusting them higher or lower.

What we claim is 1. The improved attachment for watercraft for the purpose specified, comprising a frame adapted for attachment to the craft and to project forward thereof, the same having parallel slots or guideways, bearings adapted to slide therein, a double crankshaft and connecting-rods for reciprocating such bearings, simultaneously, in opposite directions, and push-bars connected with such bearings and extending downward therefrom at a rearward inclination, and means for adjusting them higher or lower corresponding to the depth of the stream being navigated, substantially as described.

2. In an apparatus for the purpose specified, the combination, with a frame having parallel longitudinal guideways, of bearings adapted to slide in the latter, means for imparting simultaneous reciprocation to the bearings in opposite directions, push-bars attached to the bearings and projecting downward at a suitable angle and provided with joints adapting their lower parts to bend backward as the bearings are pushed forward,'racks applied to the push-bars and the side portions of the frame, and'gearing including a slidable shaft which is adapted for adjustment for locking the push-bars in any required position and for shifting them vertically as conditions may require.

3.
