To all whom it may concern-.-
Be it known that 1, PER ADoLF PETERSON, a citizen of the United States, residing at blew York, in the county of New York and State of New York, have invented new and useful Improvements in Oscillating Propellers, of which the following is a specification.
This invention relates to an oscillating propeller.
The objects of the invention are to improve and simplify the construction of such mechanism; furthermore to increase its efficiency in operation and to decrease the expenses attending its manufacture.
Vith the foregoing and other objects in view, which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, as a practical embodiment thereof.
In the accompanying drawing forming part of this specification; Figure 1 is a side elevation of the rear portion of a boat equipped with the improved propelling mechanism of the present invention. Fig. 2 is a plan view thereof. Fig. 3 is a side elevation illustrating a modified form of the invention. Fig. 4 is a similar view showing the mechanism in a different position. Fig. 5 is a plan view. Fig. 6 is a detailed horizontal section. Fig. 7 is a side view of a boat illustrating the application of my invention thereto in the form of side oars, the paddle construction being also shown. Fig. 8 is a plan view of the same. Fig. 9 is a broken transverse section of the boat, the oar operating mechanism being shown in elevation.
Like reference numerals indicate corresponding parts.
The reference numeral 1 indicates the rear portion of a boat which may be of any suitable size, form and construction. The boat 1 preferably is provided with seats 2 and 3, the seat 2 being intended for the person who is to propel the boat. It is one of the objects of my invention to enable the person who is propelling the boat, to face forward.
Extending across the boat, preferably in advance of the seat 2, is an operating crank 4 the ends of which extend through the side boards of the boat and are pivotally connected in any suitable manner with levers such as 5 which are disposed preferably one on each side of 'the boat. Each of the levers 5 is pivotally connected at its forward end. with a supporting crank such as 6 which preferably is slightly longer than the terminal crank portions of the operating crank 4; as indicated in Fig. 1. Pivotally connected with the rear end of each lever 5 is a blade 7 which is formed with oppositely extending wings 8. Pivotally connected with the blade 7 in any suitable manner as indicated at 8 is a pair of paddles 9 which are adapted to fold flat against each other in any suitable manner when the blade is moved forward, and to spread out like the foot of a duck when the blade 7 is moved in a rearward direction. The blades 9 preferably are formed of metal and are hinged together as shown at 10.
Pivotally connected with the upper end of each blade 7, as shown at 11, is an upwardly bent, forwardly extending link 12 which is pivotally connected at its forward end to the boat 1 as shown at 13.
By rotating the operating crank 4 the lever 5 is caused to move the blade 7 back-and forth in the water. Each time the blade 7 is moved in a rearward direction, the paddles 9 cause the boat to be propelled forward.
The construction illustrated in Figs. 3 to 6 inclusive, is the same as that illustrated in Figs. 1 and 2, except that the paddles 99 are dispensed with, and a single paddle 9 is pivotally mounted on each of the blades 7. The blade 9 is provided with an upwardly extending rod 14 which is ournaled in suitable bearings 15 upon the blade 7 and is formed at its upper end with a crank portion 16 which is surrounded by a small collar 17 secured in any suitable manner to a link 18 attached at its forward end to the lever 5 as shown at 19. The rear end of the link 18 is bent downward so that it is disposed below the pivot point 20 of the link 5 and blade 7, as shown clearly in Fig. 4. For this reason. as the blade 7 is moved forward, the link 18 causes the paddle 9 to fold fiat against the blade 7 as shown in Fig. 3, and when said blade 7 is moved rearward, the paddle 9 is caused to assume a position at an approximate right angle thereto.
As shown in Figs. 7, 8, and 9, the invention is applicable to both oars and paddles in about the same manner. The inner ends of the oars 20 are jointed at 21 to the upper edges of the sides of the boat in any suitable way for free universal movement. At a suitable distance outward therefrom they are supported on an upright staff 22 carried at IIO the outer extremity of an arm 23, which proj ects laterally from the side of the boat at the water level or thereabout, said arm preferably being a rigid extension of one end of a lever 23 disposed along the outside of the boat and at its other end pivoted on the Wrist pin of a crank 24, the shaft of which is pivoted in the side of the boat in any suitable manner. The said lever 23 is also pivoted on the wrist pin of another crank 25, the shaft 26 of which extends through the side of the boat and has a hand crank 27 attached to operate the oar, which it will be seen will thus have the requisite forward and backward and upward and downward motions imparted to it by turning the hand crank, the operation of the oar being such as to drive the boat either way according as the crank is turned in one direction or the other. The crank 24 is a fulcrum of the lever 23 to maintain the oar supporting staff 22 in the upright position while subject to the movements imparted to it by the hand crank 27. The said crank 24 also allows the forward and backward movement of staff 22, said crank being preferably longer than the crank 25 and swinging forward and backward instead of revolving, by which stopping on dead centers is avoided. The oar 20 is slotted at 28 for its connection with the staff 22, so as to allow the requisite freedom for their respective movements without conflict. The oar rests on a collar 29 that is adjustable up and down on the staff 22 to vary the height of the oar as may be necessary as the draft of the boat varies by light and heavy loads. A nut sets the collar as required and a keeper of any kind may be employed above the oar to prevent it from escaping from the staff. I11 this example I represent another collar 31, and a check nut 32 for such purpose but any suitable device may be employed.
In the ap lication of the hand driving device to pad dles as 32, the crank 33 of the shaft 34, operated by the hand crank 35, may be connected to a lever 36, which may either have a crank 37 for its fulcrum or a slide way, and is jointed at 38 to the paddle arm 39, so as to suspend the paddle which at the up er end of its arm is pivoted at 40 to the pa dle controlling link 41 pivoted at 42 to the side of the boat, so that the rotating hand crank 34, operates the paddle suitably for propelling the boat. In this arrangement also reverse movements of the hand crank will operate the paddle reversely.
The oar and paddle blades may have duplex and expanded construction of any suitable kind as indicated in Figs. 1,2 and 3 if desired.
It will be seen that the cranks of each side of the boat may have such angular relation to the hand cranks, that while the hands of the operator both work in unison, the oars or paddles will work alternately in respect of each other, and if desired, the hand crank shafts of each side may be connected together for positively working in unison.
Although I have only represented in the drawings and described herein hand cranks as the means of operating the oars and pad dles, I do not mean to be limited thereto, for
it is obvious that steam, electric, spring or other power apparatus may be employed as well, and I intend to avail myself of any suitable power a paratus when desired.
Having thus escribed the invention what is claimed is new is 1. In a propelling mechanism for boats, the combination of a lever pivotally connected directly to the boat, means for reciprocating said lever on its movable support, a blade pivotally connected to one end of the lever, a paddle carried by said blade, and a pivotal su port for the upper end of said glade, sai support being connected to the oat.
2. In a propelling mechanism for boats, the combination of a lever pivotally connected directly to the boat, means for reciprocating said lever on its movable su port, a blade pivotally connected to one en of the lever, a paddle carried by said blade, and a (pivotal support for the upper end of said bla e, said sgupport being pivotally connected to the oat.
3. In a propelling mechanism for boats, the combination of a lever, a crank support intermediate the forward end of said lever and the boat, an operating crank connected with said lever 1n rear of its support, a blade ivotally connected to the rear end of the ever, a addle connected to the lower end of said b ade, and a link pivotally connecting the upper end of the blade and the boat, said link being of less length than the lever.
4. In ropelling mechanism, the combina tion of a oat, an operating crank and a lever connected with sa1d operating crank intermediate the ends thereof, a supporting crank pivotally connected with said lever at the forward end thereof, said lever crank being longer than said operating crank, a blade pivotally connected with said lever at the rear end thereof, a paddle connected with the lower end of said blade, and a link pivotally connected with the upper end of said blade and with said boat.
In testimony whereof, I aflix my signature in presence of two witnesses.
