, Specification of Letters Patent. I
Patented July a, 1916.
Application filed November 6, 1914. Serial No. 870,686.
To all whom it may concern:
Be it known that 1, JOHN PETERSEN, a subject of the Emperor of Germany, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Manually- Operated Screw-Propellers; and I do hereby declare the following 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 a manually operable driving mechanism for screw propellers for boats.
The invention has for its object to provide a mechanism of this character including a plurality of pivoted hand levers adapted to be oscillated by the crew ofthe boat to drive the propeller and propel the boat.
Another object is the provision in a device of this character of novel and eiiicient driving means between the pivoted hand levers and the screw propeller.
With these and'other objects in view,'the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which:
Figure 1 represents a top plan view, partly broken away, of a boat equipped with the improved propeller operating mechanism. Fig. 2 represents a longitudinal sectional view, partly broken away, through the boat, and Fig. 3 represents a transverse sectional view 011 the line 33 of Fig. 1. Fig. 4 represents an enlarged detail sectional view on the line 4-4 of Fig. 1.
Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the hull of the boat having the usual keel 6. A screw propeller 7 is secured upon a shaft 8 rotatably mounted in the stern of the boat and the inner end of said shaft extends into a frame structure 9 andcarries a gear wheel 10. Shafts 11 and 12 are rotatably mounted in the frame structure 9 above and below the shaft 8 and said shafts are provided with gear wheels 13 and 14, the gear wheel 13 being preferably larger than the gear wheel 14. The shafts 11 and 12 are slidably mounted within the frame structure 9, and ahand lever 15 is pivotally secured to the frame structure 9 on a post 17. Below its pivotal axis the hand lever 15 is provided with a laterally projecting pin 16 engaged within a circumferential groove formed in the lower shaft 12, whereby longitudinal movement is imparted to the shaft 12 by the lever 15. Sleeves 18 are rotatably mounted upon the shafts 11 and 12 but are locked against longitudinal movement thereof. The sleeves 18 are pivotally connected with the upper and lower ends respectively of a lever 19 pivotally secured at 20in the frame structure 9, whereby when longitudinal movement is imparted to the lower shaft by the lever 15 the upper shaft 11 is moved in an opposite direction.
A pair of shafts 21 are mounted transversely and in spaced relation within the hull 5 of the boat, and sprocket wheels 22 are keyed on said shafts adjacent the opposite extremities of the latter. Chains 23 are operatlvely positioned over the sprocket wheels 22 and are disposed longitudinally of the boat, as illustrated in Fig. 1, and adjacent the sides of the latter. A plurality of hand levers 24 are pivotally mounted in brackets 25 secured to the sides of the boat, and sleeves 26 are slidably mounted upon the outer ends of said levers adjacent their pivotal axis. U-shaped frames 27 are secured at their free ends to the'sides of the boat, and blocks 28 are slidably mounted on the web portions thereof. The sleeves 26 and blocks 28 are pivotally connected by rivets 01' pins 30. Pawls 31 are pivotally mounted in the rear ends of the blocks 28 and are adapted to cooperate with the links of the chains 23 to drive the latter in the direction of the arrows in Fig. 2, when the levers 24 are operated.
A bevel gear wheel 33 is keyed centrally of the rear shaft 21 and meshes with a bevel gear wheel 34 keyed on a shaft 35 rotatably mounted in the frame structure 9.
A train of gears 36 connects the upper shaft 35 with a shaft 37 rotatably mounted in the lower portion of the frame structure 9 and carrying a gear wheel 38 meshing with a gear wheel 39 keyed on a shaft 40. A fly wheel 41 is keyed on the shaft of one of the gears 36 and is supported in the frame structure 9. Gear wheels 42 and 43 keyed on the shafts 12 and 11 respectively mesh with the gear wheels 38 and 39 and are of a width suiiicient to insure said gear wheels being constantly in mesh with the wheels 38 and 39 regardless of the respective positions of the shafts 11 and 12.
In use, the ships crew are seated upon the usual seats arranged rearwardly of the levers 24, and the latter are oscillated, re-
ciprocating the blocks 28 and the supports 27 through the sleeves 26 and pins 30; Re-
oiprocation of the blocks 28 and pivoted pawls 31 causes the upper portions of the chains 23 to be carried forwardly at each forward stroke of the pawls 31, thus rotating the shafts 21 and'imparting rotary movement to the propeller shaft 8 through the bevel gear wheels 33 and 34, train of gears 36, gear wheels 38, 39 and 43, shafts 11 and gear wheels 13 and 10. When the upper extremity of the hand lever 15 is swung forwardly the gear wheel 14: is thrown into mesh with the gear wheel 10 and the gear wheel 13 is simultaneously thrown out of mesh with the gear wheel .10 and thus the propeller shaft 8 is driven from the shaft 37 through the gear wheels 38 and 42, shaft 12 and gear wheels 14 and 10 at a relatively low speed.
What I claim is:
1. A device of the character described comprising a boat, a screw propeller rotatably mounted in said boat, a plurality of hand levers pivotally mounted in said boat, chains adapted to travel under said handlevers, pivoted pawls slidably mounted above said chains, means connecting said pawls with said hand levers, and driving connections between said chains and said screw propeller.
2. A device of the character described comprising a boat, a screw propeller rotatablv mounted in said boat, a plurality of hand levers pivotally mounted in said boat,
Copies of this patent mly be obtained for chains adapted to travel under said hand levers, sleeves slidably mounted on said hand levers, pawls associated with said slidable sleeves operatively engaged with said chains, and variable feed-driving connections between said chains and said propeller.
3. A device of' the character described comprising a boat, a propeller rotatably mounted in said boat, a plurality of hand levers pivotally mounted in said boat, supports mounted below said hand levers, chains adapted to travel below said supports, blocks slidably mounted on said supports, pawls pivotally secured in said blocks and adapted to cooperate with said chains to drive the latter in one direction, connec tions between said levers and said blocks, and driving connections between said chains and said screw propeller.
4. A device of. the character described comprising a boat, a screw propeller rotatably mounted in saidboat, a plurality of hand levers pivotallymounted in said boat, sleeves slidably mounted on said hand levers, supports secured to said boats under said hand lever, blocks slidably mounted on said supports, chains adapted to travel below said supports, pawls pivotally secured in said blocks and adapted to cooperate with said chains to drive the latter in one direction, means pivotally connecting said sleeves with said blocks, and driving connections between said chains and said screw propeller. r
In testimony whereof I affix my signature in presence of two witnesses.
