l 4L) GUGLER. 'VIBRATING-PROPELLER.
Patented-March 7 wnuzssis ATTnnNEY UNITED STATES PATENT QEFIGE.
LOUISGUGLER, OF MILWAUKEE, WISCONSIN.
IMPROVEMENT IN VIBRATING PROPELLERS.
Specification forming part of Letters Patent No. 174,419, dated March 7,1876; application filed october 16,1875.
To all whom it may concern: f
Be it known that I, LoUIs GUGLER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and Improved Propeller, of which the following is a specication In the accompanying drawing, Figure 1 represents a side elevation of my improved propellin g device for vessels; Fig. 2, a horizontal section of the same, on the line c c,Fig.-1; and Figs. 3 and 4, respectively, front view and horizontal section on line w, Fig. 3, of a modication of the paddles or wings.
Similar letters of reference indicate .corresponding parts.
' ing of special advantage for cana-l and smaller boats.
The invention consists of a series of verticallyhin ged paddles or wings that are mounted to a reciprocating frame, sliding in horizontal guides of the vessel. rlhe position ofthe paddles for forward or backward motion is produced by a lever-operated rack-bar engaging pinions of the bucket-standards.
In 'the drawing, A A are the horizontal guide-bars, which are attached tothe side, stern, or other suitable part of the vessel, and made of sufcient length for the stroke of the paddle-frame B. The. paddle-frame B is operated by means of a horizontal shaft, B', that slides in a stuffing-box of the vessel, reciprocating motion being imparted to shaft and frame by suitable power. The vertical stiffening-pieces of the paddle-frame are Inadetapering or wedge-shaped, to furnish'as small a degree of resistance to the water as possible. The paddles or wings C are hinged to verticallymounted standards D, which are also of tapering or wedge shape, and pivoted, at top and bottom, to the reciprocating frame B.
The paddles C swing according to the position of the standards and the motion of the frame, folding up in one direction, and spreading out at right angles to the frame in opposite direction for acting on the water.
The paddles offer, in folded position, no resistance to the water, and are provided with rubber or other cushioning devices a, for
smoothening the folding up, and holding the paddles in parallel position for the ready entrance of the water that opens them for the propelling action on the water.
The'standards-D are provided with flanges or seats b, that furnishl an even support along the entire length of the paddles, which are made narrow for passing more readily through the water.
lf it is desired to obtain a more powerful stroke, lateral paddle-frames with two sets of hinged paddles, as shown in Figs. 3 and 4,'
may be employed, by which the action of the paddles is increased, while the width of the paddles is not increased.
The paddles C are adjusted for forward or backward propulsion of the vessel by means of a sliding rack-bar, E, that engages pinions E of the rack-standards. The rack-bar E 1s guided in-a stuffing-box of the .vessel and in supports of the paddle-frame B, and operated by a lever, F,fulcrun1ed to the drivin g-shaft B.
By throwing lever F in one direction, the paddle-standards swing into position forforward propulsion By moving the lever in the opposite direction, the standards are turned and the paddles carried in position for propelling the vessel in backward direction, in which position they are shown in the drawing.
This system of paddles may also be made available for the purpose of steering the vessel by making the guide-bars movable, and
carrying the whole paddle-frame, by suitablemechanism, to one side or the other, so that the paddles serve for propelling and steering the vessel in a very effective manner.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of grooved frame A, reciprocating frame B, the standards D, pivoted in the latter, and having seats b, and the pad- Y dles C, hinged to the standards, and having cushions a, as and for the purpose speciied.
