Description
Feb. 19, 1963 J. R. BILLINGHAM JET DEVICE FOR WATER SKIS Filed Jan. 28, 1958 INV EN TOR.
AT RNEi.
3,87'7,d1.6 HET DEVICE FER WATER SKES James R. Biiiingharn, 9 Harvey Drive, Short Hiiis, NJ. Filed Jan. 28, 1958, er. No. 711,6ti9 4- Qlainis. (Ci. 9-419) This invention relates to a jet device for water skis which may be used in combination with widely used types of water skis. The main objects of this invention are,
First, to provide an attachment for water skis which results in producing an upwardly and rear-wardly projected jet of water at the rear end of the ski when the ski is propelled on the water as in use.
Second, to provide a water jet member which can be quickly applied to or removed from standard or widely used types of water skis, that is, water skis of the flat cross section usually having upturned forward ends.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
FIG. 1 is a view largely diagrammatic illustrating a ski jet and member combination embodying my invention in use.
FIG. 2 is a fragmentary plan view of the jet member attached to a ski.
FIG. 3 is a side elevational view, the ski being in section on a line corresponding to line 33 of FIG. 2.
KG. 4 is a fragmentary view, the ski being in sections on a line corresponding to line 4-d of FIG. 2.
FIG. 5 is a front perspective View of the jet member of my invention.
In the accompanying drawing, 1 represents water and 2 a motor boat. The ski 3 is of the flat cross-sectional type having an upturned front end 4. A pair of skis are indicated in FIG. 1. The water jet member or device of my invention comprises a body portion 5 having a forwardly facing recess 6 dimensioned to receive the rear end of the ski 3. The clamping screw '7 is threaded through the top member 8 to clampingly engage the ski. The jet device or member is preferably located centrally of the ski, as is illustrated in FIG. 2. A discharge nozzle 9 projects upwardiy above the clamp portion of the jet member to discharge vertically. The jet member has an angled passage it? opening or facing forwardly and discharging through the nozzle. This passage is desirably rearwardly tapered, as is indicated by dotted lines. The discharge is indicated at 11 in FIG. 1. The height of the discharge, of course, is varied by the speed of the ski. The jet is highly attractive and aside from its attractive efiect gives an illusion of speed exceeding that of actual speed.
I have not attempted in the accompanying drawing 3,77,fil6 Patented Feb. 19, 1963 ice to iilustrate parts in their relative proportion, and as a matter of fact while skis of the type illustrated are more or less standardized they do vary considerably in dimensions, but I have iliustrated and described my invention in a highly practical embodiment thereof.
Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is:
1. In combination, a water ski having a flat bottom surface extending from edge to edge thereof and forwardly from its rear end for the major portion of the length of the ski, and a water jet member provided with a forwardly facing recess fittingly receiving the rear end of the ski, said jet member being provided with a clamping screw disposed above the recess therein in clamping engagement with the top of the ski, said jet member having a centrally disposed upwardly projecting discharge nozzle at the rear of the ski and an angled rearwardly tapering passage opening forwardly below the ski and discharging through said nozzle.
2. In combination, a water ski having a flat bottom surface extending from edge to edge thereof and forwardly from its rear end for the major portion of the length of the ski, and a water jet member provided with a forwardly facing recess fittingly receiving the rear end of the ski, said jet member being provided with a clamping screw disposed above the recess therein in clamping engagement with the top of the ski, said jet member having a passage opening forwardly below the ski and discharging upwardly at the rear of the ski.
3. A jet member provided with a forwardly facing recess adapted to receive the rear end of a water ski, and with a clamping screw disposed above the recess for clamping engagement with the top of a ski, said jet member having an upwardly projecting delivery nozzle, and an angled rearwardiy tapering passage opening forwardly below the screw and discharging through the nozzle.
4. A jet member provided with a forwardly facing recess adapted to receive the rear end of a water ski, and with a clamping screw disposed above the recess for clamping engagement with the top of a ski, and a passage opening forwardly below the screw and discharging upwardly at the rear of the member.
