AL ONZO K. ISHAM, OF SEATTLE, WASHINGTON.
CURRENT-MOTOR.
Specification of Letters Patent.
Patented Dec. 1, 1908.
Application filed. June 26, mos. Serial No. 440,591.
To all whom it may concern.
Be it known that I, ALONZO K. IsHAM, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain newand usefullmprovements in Current-Motors, of which the following is'a specification.
My invention aims primarily to provide an improved apparatus of the above type which while being comparatively simple in construction will operate in aneflicient man:
ner.
Other objects will be set forth as the description progresses and those structural features and arrangement and combinations. of parts in which my inventionresides, succinctly defined in the'annexed claims. 3
Referring now to the accompanying drawings, in which like numeralsof reference v indicate, like H parts throughout the several views: Figure 1 is a view in top plan,.ofa
current motor f embodying my invention. Fig. 2 is ,an end View thereof. ,Fig. 3 is a section taken on line 3 3 of Fig. 2. .t is a planviewillustrating more particularly the pump mechanism and the means for releasing' the beam of my motor adjacent the end of its path of swing. Fig. 5 is a section taken on line 55 of Fig. 1,.and Fig. 6 is a section taken on line 6 6 of Fig. 5. 7 While my apparatus can be otherwise'em ployed, I have illustrated the same as connected for operating suitable pumpmech'anism comprising cylinders l in which operate suitable pistons (notshown), connected by a common rod 2, which is provided with a pair of spaced collars 3.
Referencenumeral 12 indicates abutments whichhave inclined'upper faces over which the inner end portions of stops 10 ride as the blades reach the end of their. active strokes, to effect releasing of said blades.
Carried by each hub 7 are fingers 13 for engagement with suitable abutments 14 arranged to be'engaged by said fingers, as the lowermost blades approach the end of their inactive stroke, to rotate the hubs 7 to move the upper blades so that the water can. engage the same. 7 v
In operation, beam 6 is swung back and forth by the action of the water on blades 8, the blades of each pair'being. alternately moved to be engaged by the water as will be readily understood in'.view of the following.
lEteferring'jnOW to Fig. 1, beam 6 has' been swung by the action of the water on the lower blade8 on the right, and said blade having heen released by its stop 10. striking the adjacent abutment 12, is feathered, by the action of the water (see Figs. 2 and 3), so as to ofier but little resistance during its return or inactive movementwhich is ef- "fec tedlby the action of the water on the lower bladejS on the left. {As the blades reachthe end of their active strokes one finger on the opposite hub 7 engageslits abutment 14 thereby effecting rotation of said hub to swing the upper blade so that its outer end portion engages. in the water, Thecurrent then acts to set the blades in vertical position.
prevent any accidental backward movement of the piston rod, after finger 15-has been moved from between the collars 3 thereof I provide suitable set devices 17, 17 arwill therefore be suflicient for a clear un-der- I standing of their construction and operation. This comprises a strike arm 18, pivoted at 18 to the support 4, which lies in the path of beam 6 and an arm 19 movable therewith and arranged to engage the foremost collar 3. Now when beam 6 strikes arm 18, it swings, the same, as indicated by broken lines in Fig. 6, causing arm 19 to engage said collar 3 and move the. piston rod slightly to insure of the collar lying clear of the adjacent offset end portion of slot 16. Af ter swinging strike arm 18 toasubstantially vertical position, beam 6 moves directly above the, same so that the broad fiat upper face of said strike arm will bear against its under side, thereby holding said strike arm from movement. WVhen beam 6 swings from over the set devices 17, 17, they swing by gravity to their forwardly inclined or normal positions (see Fig. 6).
Having thus described my invention, what I claim as new, and desire to secure by LettersPatent of the United Statesof America, 1s:
