FEATHERING PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 532,887, dated January 22, 1895.

Application nea April 4, 1894.

To @ZZ 'whom it may concern.'

Be it known that I, CHARLES ALBERT LONG, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Motor-Wheels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide improved means for propelling a vessel, or vehicle, or for establishing a rotary movement, to be transformed, or transferred, to the propulsion, or operation, of machinery, and is especially adapted for vuse as a paddlewheel for steam-boats.

My invention consists in the construction, combination and arrangement of parts here-` inafter set forth, and pointed out in my claim.

Figure 1 is a side elevation of the complete device, the dotted lines indicating the orbits of rotation of some of the parts, and the position assumed by those parts relative to their orbits. Fig. 2 is a plan view of Fig. 1. Fig.

-3 is an enlarged horizontal sectional view on the indicated line 3-3 of Fig. 1, taken on the opposite side of the machine. Fig. 4 isa front elevation, showing the means of'retaining the paddles in a given position relative to the shaft. Fig. 5 is a vertical sectional view on the line 7-7 of Fig. 6.

In the construction of the machine as shown, the numeral 10 designates a shaft, mounted in suitable bearings 11, 11, and having a crank-arm 12 keyed to one of the outer projecting end portions thereof, which said crankarm is adapted to be employed either to connect the shaft with a prime mover, or with machinery to be driven. Concentrically mounted upon the shaft 10, between the bearings 12, and on opposite sides of the machine, are heads 13, 14, which said heads are identi-- cal in construction, and are provided with radial arms 15, 16, 17 and 18. Rotatably mounted in, and connecting the arms 15, 16, 17 and 18 of one head to the like arms of the remaining head, are crank- shafts 19, 20, 21, 22, which said crank-shafts have out-turned portions on one end for a purpose hereinafter to be made plain.

As shown in Figs. 4 and 5, a portion of each of the crank- shafts 19, 20, 21, 22 is squared,

seria No. 506,246. (No miei.)

or made angular, and mounted upon said angular portions are cross-bars 23, 24, 25, 26, arranged in pairs, the outer ends of which crossbars are bent laterally at right angles to the body portion thereof, and have secured thereto blades, or paddles, 27, 28; and 29, 30; and 31, 32; and 33, 34; arranged in pairs, as indicated in Figs. 1 and 2.

Bifurcated clips 35, 36 are mounted upon veach of the squared portions of the crankshafts 19, 20, 21, 22, the bifurcations in said clips embracing said squared portions, the end portions of said clips being bent over and caused to embrace the top and bottom edges of the cross-bars 23, 24, 25, 26, respectively.

Rigidly mounted on the bearings 11, 11, and eccentric relative to the shaft 10, are bearingplates 37, 37, which said bearing-plates are provided, near their peripheries, with horizontally aligning apertures, through which the shaft 10 is adapted to pass, and within which said shaft rotates. The plates 37, 37 are xed to the bearings 11, 11 by gudgeons 38, 38, and are adapt-ed to remain in a stationary position at all times.

Rotatably mounted upon, and concentric with, the plates 37, 37 are supplemental heads 39, 40, which are provided with radial horizontally opposite arms 41, 42, 43, 44,'which arms are attached to the projecting outturned end portions of the crank-shafts, 19, 20, 2l, 22 in a pivotal manner. The heads 41, 42, 43 and 44 rotating on fixed plates 37, 37 are moved with the heads 15, 1G, 17 and 18, when the latter rotate.

It will be observed that the orbit of rotation (indicated by the dotted circle 45, Fig. 1),

of the heads 39, 40 is eccentric to and bisects the orbit of rotation (indicated by dotted line 46, Fig. 1) of the heads 13, 14, and that the heads 39, 40 are dependent for their movement of rotation upon the connection thereof with the heads 13, 14. It will also be observed that the relation of the axes of rotation of the heads 13, 14, and the heads 39, 40, is such that theapices of the arms of one head, relative to the arms of the remaining head, have, at all times, the same distance of separation. It, therefore, follows that power being applied to the crank 12, the heads 13, 14 will be rotated through the medium of the shaft 10, such IOO movement of rotation carrying the body portions of the shafts 19, 20, 21, 22 through the orbit 46, and the normal tendency of said shafts 19, 20, 21, 22 would be to rotate, were it not that said shafts having pivotal connections withthe arms of the said heads 13, 14,- and having cranks thereon pivotally engaged by the arms 41,42, 43,44, on the supplemental heads 39, 40, are retained non-rotatable upon individual axes. It is further shown that, by reason of the non-rotatability of the shafts 19, 20, 21, 22, devices carried upon said shafts, and rigidly connected thereto, will also he non-rotatable, and it, therefore, follows that the paddles carried on said shafts will re main, at al1 times, in positions having their greatest transverse dimensions in vertical planes. This construction and positioning is essential for the reason that, by reason thereof, the broad side of each paddle may be thus contacted with a resisting body, such as water, and afford a maximum degree of power transmitting, or receiving, surface, by reason of such contact.

It will be observed that each of the paddles, comprising a pair, has an orbit independent of the orbit of each other paddle of the same pair, the two orbits being indicated by the dotted lines 47, 48 in Fig. 1.

The combination, in an improved motor wheel, of the opposite heads 13, 14, supplemental heads 39, 40, radial arms 15, 16, 17 and 18 on said heads 13 and 14, radial arms 41, 42, 43, 44 on said supplemental heads 39 and 40, suitable mountings for all of said heads, whereby the radial arms of the heads 13 and 14 and the radial arms of said supplemental heads will rotate in different orbits, crankshafts 19, 20, 21, 22 rotatably mounted in and connecting the arms 15, 16, 17, 18 of one head to the like arms of the opposite head, said crank-shafts having each two squared or angular-portions separated a distance, crossbars 23, 24, 25, 26 arranged in pairs and having their outer ends bent laterally at right angles to the body thereof, and mounted one upon each of said squared portions of said crankshafts, bifurcated clips 35, 36 mounted one upon each of the squared portions of said crank-shafts with the bifurcations in said clips engaging said squared portions, the end portions of said clips being bent over and caused to embrace the top and bottom edges of said cross-bars, and blades or paddles arranged in pairs and secured in position upon the bent outer portions of said cross bars, substantially as herein specified.

In testimony whereof I ax my signature in presence oftwo witnesses.
