- v Application filed a rn'aa, 1931 Serial No. 532,330, I

My invention relates to boats, more particularlyto boats of the amphibian type, and

it consists in the constructions, combinations,

and arrangements herein shown and described. H 1 t i A primary purpose of my invention is to provide a boat which will have means'zfor getting ofi the ground if unfortunate enough to get aground in shallow water, thatwill m be able to navigate shallow water, and that will be able to 'go to and from bodies of water.

A further obj ect of my inventionis to prov vide a boat of the type described that is able to raise its hull-above water so that the same may be cleaned, repainted, repaired or inspec'ted While theboat is afloat, thus avoid ing the expense of going to dry-dock or onto marine ways. r A still further object of my invention is m to provide a boat having'verygreatstability,

thus enabling the same to proceed under power in heavy weather. I 7

A yet further object of my invention is to I provide a-device of the type described which has few parts, is-simple to manufacture, and

does not get out of order easily, 1

Other objects and advantages will appear as the specification proceeds, and the invention will be more particularly defined in the appended claims. My device .is illustrated in the accompanying drawings forming a part of this application, in which Figure 1 is an elevational view of my invention, r 5

Figure 2 is a longitudinal sectionalview of my invention with parts thereof-shown in elevation, V

Figure 3 is an 'end elevational view of 'a part of my invention with the parts in one operative position, r

Figure 4 is a similar view withthe parts in another operative position,

-igure'5is a fragmentary detailed view of aportion of the device, and I Figure 6 is a partlyschemat'io and partly detail view of another portion of the device. In carrying out my invention, I make use 250 of an 'ordinary'boathull 1, equipped with an engine, 2, or other suitable power means, or

This frame member, 18, supports between its 'tion and depression of the drum members, 9.

adapted for manual propulsion in the case of smallboats of this typewhich maybe operated by hand without any engines whatsoever. c This boat hull, 1, on either side thereof, is

equipped with a land and sea propulsion means, generally indicated at 3,-e'ach of said means consisting of la pivotally mounted frame, 4, swivelled as indicated at 5, to the side of the boat, and, swivelly mounting at its opposite end a fra1ne,-'6. This frame, 4, consists of the angularly formed side members, 7, having abracing bar, 8, extending therebetween. It supports between its side arms, 7, a rotatable hollow hermetically sealed drum, 9, of heavy construction "having on its periphery heavy paddle blades, 10, adapted to support the drum when brought into contact with the land, or to propel the boat through Water orcarry it over the land when rotated. For raising and'lowering the drums, 9, for raising the boatabove the water, as shown most clearly inFigure 2, as vwell as; for raising the boat to enable the same to travel over land, and for propelling the boat through the water in a most-efficient manner, the frame members, 6, on each side, which in this em bodiment each consist of a pairof side arms,

11, with a vbracing arm, 12, are each con-nected to a hoist, comprising the frame member, 13, secured to the side of the boat .as indicat ed at 14 and 15, and having a bracing arm,

16, between, the;arm members, 17 thereof.

arm members,,l7, adruin hoisting mechanism, 18, which may be of suitabIe-Construction, but which is shown in thisembodiment as consisting of a rotatable drum member, 19,, havinga manual,means, 20,,for the rotation thereof, and a pawl and ratchet mechanism shown at 2-1 and 22, for-securing the drum in a desired position. The bracing arm, 16, of the frame is equipped with a,pul1ey, 2'3, mounted as shown at 24. About the pulley and thedrum the cable, '25, is passed, the ends ofIsaid' cable being connected to the" frame member, 6, as shown at '26 and 27. It

is obvious from'fthis description that rotation of'thehoisting drum will bring about ;elevam0 sprockets, 30, are mounted on the hollow driving shaft, 32, which bearingly supports the shafts, 5, pivotally supporting the frames, 4c.

These hollow driving shafts are driven by the motor, 2, through the geared connection, 33.

A clutch, 34, enables the operator to apply or means of rotation of the hoisting means thus raising the boat above the water supported *by the drums. The buckets at the end of the withdraw the power as desired.

The shaft, 32, is rotated in one direction by gears, 35 and 36, which are moved into engagement by means of clutch lever, 37, sliding the gear, 35, into mfesh'with gear, 36, the gear 35,- being splined or keyed on shaft,- 32. It is rotated in the opposite direction by means of inter-engagement between gears, 36 and 38, gear 38 being similarly splined or keyed on shaft, 32, and operated to its positions by means of clutch lever, 39.

For enabling the operator to drive one of the drums while the other remains stationary,-

clutches, 39a and 39?), are provided between each of said drums andthe gears, 35 and 38, re spectively. It can readily be understood that either of the drums can be thrown out of con- .nection with the driving means by operation depression of the drums, 9, I suspend at either end of said boat buckets, 40, which will prevent tilting motionsof the boat about the drums in a manner easily understood.

- From'the foregoing description, the use and operation of my device is easily understood. When the operator desires to utilize the invention as a boat, he simply elevates the drums by means of the hoisting apparatus and fixes the same in a desired position with the pawl and ratchet device. It is noted that this pawl and ratchetdevice is adapted to prevent motion of the hoist'in either direction of rotation. He then operates clutch, 34, and one of the gears, 35 or'38, into engagement with gear, 36, in accordance with which direction he wishes the boat to travel. It can readily be understood that the boat will be propelled by the blades on the drums in the desired direction. I

'When the operator desires to turn the boat either in the water or upon the land while the boat is in motion either in a forward or backward direction, he simply operates one of the clutches, 39a or 396, to release either the left or right drum, allowing the other drum to rotate, thus turning the boat. He may control the speed-of the boat in either direction by means of the rheostat, 39c.

It is understood that, of course, any suit? able conventional tra-nsmissioncontrol could be utilized in place of the clutch system shown by applicant.

I It is also understood that the drums will act as stabilizing means to keep the boat afloat and topropel it in the proper direction during storms and heavy weather.

When the operator desires to elevate the boat above the water for purposes of cleaning the hull of the same or for other operations, he simply depresses the drums by boat being filled with water will prevent tilting of the same about the drums.

When the operator desires to use the device as a land vehicle, he need simply operate the hoist to lowerthe drums as inflthecase of elevating the'boat above the water and set the drums in motion in the desired directionby means of the gears, 35, 36, and 38, and the clutch, 34. Of course, during this operation, additionalv supporting means must be sup: plied for either end ofthe boat to prevent thesame from dragging. This can easily be taken care of by attaching the same to another vehicle or using an additional carriage (not shown) under either end.

It is. understood that in the case oflargeboats a power hoist might be utilized without deviating from my invention. It is further understood that if desired the drums may be driven by a separate power means to enable the operator to utilize the same by moving oneqor the other for steering of the boat or vehicle. 1 A

It is thus seen that I have provided a boat which is adapted to travel on land or navi gate' on' sea and which is further adapted to elevate itself above the sea when desired.

It is further seen that I have provided a boat that is adapted for stable operation'during heavy weather, that can get off the ground if unfortunate enough to get agroundin shallow water, and raise itself up on the shore on its own power when necessary. r What I desire to claim and secure by Let-. ters Patent is:

1. A boat, comprising a hull, power means positioned in said hull, rotatable drums on either side of said hu'll,;propulsion blades on said drums, pivotal arms supporting said drums, and means for oscillating said pivotal arms to depress and elevate said-drums for raising and lowering said boat, consisting; of members pivotally mounted to said arms, hoistingframes secured to the hull, drums secured to said hoisting frames, pulleys se' cured to said hoisting frames, endless flexible members secured at their ends to said pivotally mounted members and trained about their respective pulleys, and drums, means for rotating said drums, and means for securing said drums in a desired position. v

2. A boat, comprising afhull, drums posi tioned on either side of said hull and having propulsion blades thereon, pivotally mounted arms for mounting said drums, means for rotating said drums for propelling the boat,

and means for raising and lowering said drumsto raise and lower the hull relative to the water, consisting of a hoist pivotally related to the ends of said arms, and pawl and ratchet means associated-with said hoist for securing the same in a desired position.

3. A boat, comprising a hull, drums positioned on either side of said hull, means for raising and lowering said drums to raise and lower the hull, and buckets connected to either end of said hull to prevent tilting of said boat about said drums when said hull is in the elevated position.
