To all whom it may concern.-
--Be it known that I, Jason S. BISHOP, of Olean, in the county of Oattaraugus and'State of New York, have invented certain new and useful Improvements in Propeller-Wheels,
and'I' do hereby declare thefollowing to be a full, clear, and exact description of the inv'en tio'n, such as will enable others skilled" in the art to which it appertains to make and usethe same.
"i y propeller-wheels and their operating-gear.
I Thepbject of my invention is to increase the speed of boats; and to do this I provide a simple, compact, and practical mechanism for the operation oftwo propeller-wheels in the same axial line, (one being a right-handed wheel and the other a left,) and in a manner to permit them to rotate in opposite directions, one in the rear of the other. l v A further object is tofurnish a means for same axial line, or one in rear of the other,
'the operating mechanism being arranged to,
permit the arrest of motion of one wheel'while the other is operated, and also allow the re snmptionlof rotation by the idle-wheel when 'desired, so that one or both wheels may be used, as the needs of the service may dictate. With these objects in view my invention consists in certainfeatures of construction and combinations of parts, that will be hereinafter described, and pointed out in the claims.
- Referring to thedrawin'gs, Figure 1 is a plan viewof the bed-plate and gearing by which the wheels are operated, exhibitingthe manner of attachment of the shafts to the gearing, portions of the, shafts being also shown. Fig. 2 is a side elevation of the bed-plate with the wheel-gearing and adjacent, portions of the shaft shown in'position. Fig. 3 is an end elevation of the bed-plate and gearing, taken from the side of the bed platenearest the engine. Fig.4 represents a longitudinal section of per tions of the wheel-shafts with the wheels located upon their respective shafts. Fig. 5 is asectional view, of one of the gear-wheels and portions of thetwo shafts, taken on theaxial OLEAN, NEw YORK, A'ssicnoa or ONE-HALF W. HIGGINS, OF SAME PLACE. J

At a desirable point within the hull ofa the vessel to whichthe wheels are adjusted at bedplate, 1), is mounted and secured onany suitable foundation to rigidly retain it in its place.
The bed-pla'te Dis preferably made ofmetal, f v r and is shown in Figs. 1,2,and3 of the drawngs. on the four. sides of which areformedjournalboxes 1 2 3 n at points midway between the corners of the frame or bed-plate.
It consists, essentially, of a square frame,
8.;- when'the The boxes 1 3, which are opposite each other,
I are intended to give support to the shafts B 0.
The box 3, which is on the side of the bed-plate D nearest the stem of the boat, is made of a capacity to receive the outer hollow shaft, B, the surface of which is rendered true where it enters this box.
The bed-plate D has a rectangular opening or space formed in it of sufiicient dimensions to receive the gear-wheels which are used to transmit motion and power from the solid shaft G to the hollow shaft B and its attached propeller-wheel A, as will be further explained.
The outer or hollow shaft, B, has a bevel gear-wheel, G, attached to it by the stud-bolts c, which are secured in the face of the wheel and enter holes in the flange b, formed on the end of the shaft, the nuts b serving to draw the wheel toward the flange by their threaded engagement with the studs 0 andpressure upon the outer surface of the flange 1), as shown i Figs. 1 and 5.
In Fig. 5 will be seen the plan of construction of the inner solid shaft, 0, where it is in contact with the'hollow shaft B. Near the inner end of this shaft an enlargement or swell, d, is produced on the solid shaft 0 that is of proper diameter to fit against the interior surface of the hollow shaft B, to hold the latter concentric with the solid shaft and yet permit it to revolve.
The position of the bevel gear-wheel G on the shaft B will locate its faced hub h in running contact with the inner face of the box 3,
box 1 of the base-plate D, and has a bevel wheel, E, loosely mounted on it that is in meshed contact with the intermediate wheels, F H. (See Fig. 1.) The shaft 0 is slotted through the center of its body at a point between the two wheels G and E, this slot at being of sufficient length to allow the clutch-hub I to be slidingly secured to the shaft 0 by a cross-pin, a, inserted in it and through the slot; or a keyway may be cut in one side of the shaft 0 longitudinally, in which a featherkey that is fitted and fastened in the clutchhub I may be located so as to permit a sliding movement of the clutchhub.
A concentric groove, m, made in the clutch huh I, may be engaged by a crdtchcd lever,in a mannerusual to such devices,to afford means for the shifting of the clutch-hub into contact with locking ears or projections formed on the adjacent face of the wheel E, or, if preferred,into holes or recesses made in this face of the wheel to lock it fast to the shaft 0, or throw it out of connection with the shaft, if desired.
In service it will be apparent that power which is applied to the inner end of the solid shaft 0 will rotate the rear propeller-wheel, A, which is farthest removed from the stern of the vessel, and if the clutch-hub I is disengaged from the wheel E the other wheel, A, will not be moved.
When it is desirable to use both propellerwheels A A, the clutch-hub I is shifted to lock the shaft 0 with the loose wheel E. This will transmit the motion it derives from this connection with the shaft 0 through the intermediate wheels, F H, to, the bevel gearwheel G, and consequently to the inner propeller-wheel, A, which will rotate in a direction opposite to that given to the outer propeller-wheel, A.
It is a well-known fact that the operation of a single propeller-wheel causes a side motion, and when a straight course is desired the rudder-blade has to be held in a certain fixed position to prevent the boat from taking a cir: cuitous route. This necessarily retards the speed of the boat. It also causes an injurious side wear on the supporting-boxes of its shaft, as well as a considerable loss of power from friction, which is due to the lateral thrust of the blade of the wheel. In my improved method of construction I overcome this sidethrust when both wheels are in use, as by the revolution of the wheels in opposite directions the action of one will balance the other and frictional resistance of the shafts in their boxes will be reduced to a minimum.
Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-
1. In propelling mechanism for boats, the combination, with a support, a hollow shaft journaled therein and carrying a propellerwheel, and a solid shaft journaled in said support and in the hollow shaft and carrying a propeller-wheel, of a gear-wheel secured to one shaft, a gear-wheel loosely mounted on the other shaft, and a sliding clutch loosely mounted on the solid shaft for locking the said loose wheel to the shaft, substantially as set forth.
2.
