Specification of Letters Patent. Patented Jllly'24,1917..

Application led September 21, 1914. Serial No. 862,850.'

To all whom it may concern:

*hullof a boat,and which is adapted to constitute a stuffing box for the propeller shaft, and a pumping connection adapted to. s uply water to the jacketof an internal comliustion engine, and which will cover a pilurality of openings in the hull in water tight relation to its inner' and outer walls, around such openings.

The drawmg illustrates a fragment of the bottom ofthe hull of a canoe in longitudinal section, showing my improved attachment also partially in section, drawn to a plne cutting the stutling box and pump cyl- 1n er.

` The bottom A of the. hull of a canoe or boat, is provided lwith an aperture a for the propeller shaft, another aperture a for a pump cylinder, anda series of apertures to receive clamping' bolts B. Clamping plates C `end D are then hull and clamped thereto by the bolts I The upper clamping plate C, 1s provided with-a bearing member or bushing E whichl projects downwardly through the aperture a and through a corresponding aperture in the lower clamping plate D. Itis also provided With an upwardly projecting cup which is internally threaded to receive a packing nut F and adapted to contain a suitable packing F. plate C also carries a cap G for a pump cylinder H, which. ca is preferably, formed integrally with mem r C and provided with an outlet nipple G" adapted to serve as a it Tis possible to dispense with packingl pipe or hose connection, such, forexample, as the rubber ltube g. `lli-here the boat hull is of wood and the surface fiat, as shovn,

e.- tween the clamping, platesand the-wa s of the hull. Otherwise it may-be employed.

Ithe tubular port K normally c fitted to the walls of the' The clamping'- The cylinder H isprovided with a p1unger H havin a tubular `socket Hl extending downwar ly therein from its upper end, and provided with an inlet port h at its lower end, communicating with a transverse bore h', which allows 'water to enter the cylinder Hthrough the plunger H. A ball valve I is'seated at the upper end of the port h, and spring J is seated in jt H and projects upwardly above t ,-;plunger and supports a cup valve seat K," provided with an outlet osed by a gravity check valve, such as the ball L. The plunger H is reduced in diameter -where it passes through the lower endv or headof the cylinder H and its range of movement is therefore limited by the cup K onthe upward stroke and'by the shoulder K on the'downward stroke. i i The driving shaftM is incas'ed in a sleeve Mwhich extends through'the stuliing box and bushing and supports a casing M in, which the ropeller shaft N- and gear wheels N and N are mounted in operative rela-- tion lto drive the propeller O. A steering wing P, .preferably of center board type', projects downwardly .from the'casing M, and shaft N carries a vcam S. Steering and reversing operations are largely rformed by revolvingthe propeller about t e axis of shaft M, but the wing P facilitates these operations and aids control. The steering movements are' communicated to the pro' peller and rudder wing P through sleeve M.

A ump operating rodv O' bears on this cam. an extends through the wall of casing M".

It supports a ring. R upon which the lower end of plunger H bears, and as ring R encircles the sleeve M', it is obvious that it may revolve'with the propellerabout the axis lof4 the -driving shaft, without being shifted out of pump operating relation. I claim-4 y A I l j 1. 4A clamping member for boat propeller attachments, provided with a bushing adapted' 'to receive an inclosin a driving shaft, and alsohaving a cylindjergsaid bushing and pump cy inder, projecting from said clamp' member in position for insertion throng contiguous vapertures in the hull of aboat. I l

2.. A clamping member for boat propeller attachments, in combination with a rotatably adjustable ldriving sha-ft sleeve, projecting through the clamping member, a pump cylinder also extending through said member adjacent to said sleeve, an integral cap on vthe clamping member into which said pump cylinder is secured, a plunger in said cylinder, a ring loosely encircling said sleeve, a. propeller, and driving mechanism therefor 'extending through said sleeve, and means including .saidloose ring for actuating the pump -plunger from said driving mechanism.

3. A clamping member for boat propeller attachments, adapted Vto be fitted tothe interior or hull of a boat, in combination with a pump including a cylindermsecured to the clamping member in a Aposition to project through the hull and an actuating member extending from the cylinder, a driving mechanism carried by thc hull and disposed below the' pump cylinder, and means associated with said driving mechanism for operating said'- actuating member of the pump.

4. 'A vclamping means for boat'` propeller attachments, comprising a clamping plate,

spaced tubular members projecting from said pla-teV for `insertion through contiguous apertures in the hull ofa boat, an auxiliary clamping plate provided with bearing apertures for receiving the tubular members, said `platebeing engageable with the hull at its side opposite the first clamping plate, means for holding said plates in clamping engagement with the hull, pump mechanism in one of the tubular members, driving mechanism extended through thc'oth'er tubular member,"

and means operable by the driving` mechanism oulivardly ot' the hull for actuating. the pumping mechanism.

5. A clamping member for boat propeller attachments,in combination with a driving shaft 'slecvc projecting through the clamping member; a pump 'cylinder also extending through said member adjacent to said sleeve,
