UNITED STATES PATENT OFFICE.
LEANDER IV. HAMMOND, OF PLAINFIELD, NEW JERSEY, ASSIGNOR OF ONE-V AI'IALF TO SAMUEL A. YVV'ALLAOE, OF NORTH PLAINFIELD, NET JERSEY.
SPECIFICATION forming part of Letters Patent No. 695,389, dated March 11, 1902:
Application tiled September 21,1901. Serial No. 76,050. (Model.)
. To @ZZ whom it may concern:
Plainfield, in the county of Somerset and State c of New Jersey, have invented new and useful Improvements in Propeller-Wheels, of which the following is a specification.
My invention relates to propeller-wheels, and has for its object to construct a device in which great prop ulsive power is attained with a small resistance.
With thisobject in view myinvention consists in the construction, arrangement, and combination of parts, asiw'rll be first fully described in the specification and then claimed.
In the drawings forming `a part of this specification, and in which like symbols of reference represent correspondingfparts in the several views, Figure l is a vperspective of the device. Fig. 2 is a side elevation of the hub-sections. Fig. 3 is a detail of one of the paddles. I
The numeral 1 designates the hub of my propeller, which comprises two funnel-shaped 0r approximately conical sections 2 and 3, placed base to base. 1
The hub 1 isapertured longitudinally to accommodate a propeller-shaft 5. The hub l is traversed by three diagonally extending grooves 4, corresponding to the number of blades 6 employed iny constructing the propeller. The grooves 4 are beveled on one side and perpendicular on the other, forming square shoulders 4ta. p
The blades 6 each have an apertured disk 6a integral therewith. The blades 6 are not plane, but are twisted or turned through an angle to the plane of the disk 6a, which angle is equal to the pitch of the screw. The blades 6 are secured by clamping the disks 6 be- 4o tween thev hub-sections 2 and 3.
Mounted on the ends of the blades 6 are members 7, having oppositely i extending flanges designed to confine the water and preventits escaping over the ends of the blades. 45
In operation the shaft 5 is revolved and the section 3, aided by the shoulders 4a of .the hub, will bore through the Water like a gimlet and throw the water outwardly toward theblades 6, thereby preventing dead water 5o in front of the screw, The blades 6 will engage the water and force the boat along. The flanges on the members 7 will prevent the escape of water over the ends and reduce the slipping of the screw to a minimum. The 5 5 rear portion 2 of the hubwill fill the void or vacuum which always forms back of the screw and lessens its grip. Thev gimlet-like action will also assist in propelling the boat.
I do not wish to be limited as `to details of 6o construction, as these may be modified in many particulars without departing from the spirit of my inventionf Having fully describedmy invention, what I claim as new,and desirefto 'secure by Letters 65 Patent, isf v In a propeller, the combination of a hub coned oft at both ends and having diagonal grooves therein, and blades mounted on said hub, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
LEANDER W.r HAMMOND.
