GEORGE B. DAVIS, 0F DAWSON, YUKON TERRITORY, CANADA.

HOOD FOR PROPELLER-WHIEELB.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed January 17, 1908. Serial No. 411,212.

To all 'whom it may concern:

Be it known that I, Gnoncn B. DAVIS, a

citizen of the United States, residing at Dawson, Yukon Territor Canada, have invented certain new an useful Improvements in Hoods for Propeller-Wheels; and to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in The object of the invention is to provide a hood or funnel for propellers whereby the same may be used in shoal water.

Wlth this objectin view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims. 1

In-the accompanying drawing, Figure 1 1s a sideview of the stern end of a boat, showmg the application of the invention thereto; Fig. 2 1s a similar view, showing the hood in section; and Fig. -3is a rear end view.-

Referring'more particularly to the-draw lugs, 1 denotes the hood, which is preferab y formed of sheet metal and is adapted to be constructed in any suitable shape, such as cylindrical, half-round, oval, square, triangular and tapering or funnel-shaped, or provided with straight sides, the same being shown in the resent instance as being substantially hal -round or semi-cylindrical at its outer endand having its sides and lower ed s tapering slightly toward the inner end? The hood is adapted to be arranged over the upper side of the propeller wheel and to pro ect rearwardly of the same and also to a slight distance ahead of the wheel .beneath the stern end of the boat, as shown.

The hood is adjustably supported in position by avertically dis osed supporting bar, 2,

arranged in suitab e bearings, 3, secured to the stern of the boat, as shown. The lower end of the bar, 2, is bifurcated to form diverging supportin plates, 4, which straddle e upper side of t e hood and are pivotally connected thereto at their lower ends.

On the bar, 2, is slidably mounted a collar, 5, which is ada ted to be adjustably secured to the bar, 2, by means of a set-screw 6, said collar forming a stop adapted to be connected with the upper bearing, 3, on the stern of the boat, whereby the hood is adj ustably supported and held in position over .the propeller wheel. On .the upper side of the hood, adjacent to the rear end thereof,

is formed a centrally disposed upwardly projecting fin, 7, with which is pivotally connected the lower end of an inclined brace bar, 8, the upper inner end of which is pivotally connected to an apertured lug, 9, on

the collar 5. The brace bar 8 is adapted to steady and steer the rear end of the hood, and together with the fin 7 is adapted to hold the hood in line with the center of the propeller wheel when drawn through the water. Byloosening the set screw, 6, in the collar, 5, the supporting bar, 2', may be raised or lowered to adjust the hood to the desired position over the propeller wheel.

- Ifdesired, the hood may be connected with the rudder soethat it will aid in the steering of the vessel and the operation of the wheel by taking water from under the vessel or from either side.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. In a hood for propeller wheels, a supporting bar having a pivotal engagement at its lower endwith the hood, and means connected to said supporting bar and hood to steady the rear end of the latter, substantially as described.

2. In a hood for propeller wheels, a supporting bar pivotally connected at its lower end to said hood,.means to adjustably secure the bar to the end of the vessel, a brace pivotally connected at one end to the outer end of the hood, and means whereb the 0p osite end of said brace is connecte to sai supporting bar, substantially as described.

3. A hood for propeller wheels adapted to be arranged over the same, a supporting. bar bifurcated at its lower end and ada ted to be pivotally connected to saidhood a 'acent to its inner end, a stop collar arrange on said bar to adjustably secure the same to the stern of the vessel, and means to support and guide the outer end of the hood, substantially as described.

4. A hood for propeller wheels adapted to be arranged over the same, a su porting bar bifurcated at its lower end an adapted to be pivotally connected to said hood a jacent to 1ts inner end, a stop collar arranged on said bar to adjustably secure the same to the tudinal upwardliy projecting fin arranged on the upper side 0 said hood, and. 'an ob (uely. disposed brace ada ted to connect sai fin end pivotally stern of a vessel, a centrally disposed longiwith said stop co ar, substantially as described.

5. A hood for propeller wheels comprising a longitudinally disposed curved plate, the sides of which ta er toward its inner end, a supporting bar aving a bifurcated lower connected to said hood adjacent to its inner end, bearings arranged on the stern of the vessel to receive said bar, a stop collar arranged on the latter above said became bearings, a set screw to hold said collar in adjusted position on said-bar,

osed longitudinal upwardly projecting fin an obliquely disposed brace" adapted to connect said fin with said collar, substantially as described. Y

In testimony whereof I have hereunto vset my hand in presence of two subscribing wita centrally disormed on the rear portion of said hood, and v
