Riley, 11431 94th Ave, North Surrey, British Columbia, Canada Filed Feb. 21, 1962, Ser. No. 174,734 3 Claims. (Cl. 69-54.5)
This invention relates to improvements in hydraulically-operated mechanisms.
It is an object of the present invention to provide a hydraulically operated piston that will substantially increase the mechanical advantage in engines and tools.
Another object of the present invention is to provide a hydraulically operated piston that will increase substantially a given force, as applied to the primary piston head, through hydraulic conversion, by actuation of a secondary piston head.
Another object of the present invention is to provide a hydraulically operated piston that will substantially increase the output horsepower of an internal combustion engine, and also may be utilized in a power tool for driving or assisting driving fasteners into material, or making holes in concrete or other material.
Other objects of the invention are to provide a hydraulically operated piston bearing the above objects in mind which is of simple construction, has a minimum number of parts is inexpensive to manufacture and efficient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:
FIGURE 1 is a vertical view, comprising the present invention, shown broken away, and in elevation; and
FIGURE 2 is a bottom plan view of FIGURE 1.
Referring now more in detail to the drawing, a power piston 10, which may be the power piston of an internal combustion power device, made in accordance with the present invention, is shown to include a circular wall 12, having an upper end wall 14, and a lower endwall 16, and the outer periphery 18 of wall 12 is in slidable engagement with the inner periphery 20 of elongated cylinder 22. A central and upwardly extending projection 24, having a central opening 26, is fixedly secured to piston 10. A small diameter cylinder 28 extends through the opening 26 and projects outwardly and centrally from cylinder 22. Hydraulic fluid 29 entirely fills piston 10, and part of the upper end of cylinder 28. An elongated circular piston 30 is slidably received within the cylinder 28, and is fixedly secured at its lower end to an elongated and circular rod 32, which extends centrally therefrom through the opening 34 of cylinder 28. A circular inner wall 36 is fixedly secured within the opening 37 of cylinder 22, and cylinder 28 is fixedly secured within a transverse and central opening 38 of wall 36 so that cylinders 22 and 28 form a rigid structure.
3,165,8h5 ?atented Jan. 19, 1865 In operation, a given force is applied to end wall 14 of piston 10, which will urge it downward into cylinder 22. In view of the projection of the end of relatively stationary cylinder 28 within moving piston 10, the volume of liquid forced out of the interior of moving piston 19 into the interior of cylinder 28 and acting on piston 33 is larger than the volume change occuring within cylinder 28 due to the relative movement between piston 19 and 3b and the result is a longer stroke of piston 39 relative to its cylinder 28 than if cylinder 28 were omitted and piston 3i? were to slide within opening 26 and piston 16 directly. The force acting on piston 36 is the difference between the area of piston head or wall 14 and the projected area of the end of cylinder 28 within piston 1i) multiplied by the mean unit pres-.
sure on top of wall 14.
It will thus be recognized that the aforementioned hydraulic principle utilized in the above manner, mechanically, serves to increase the efiiciency of combustion engines of the internal and external type, also, increasing the speed and efliciency of fastener driving tool, or hole-making devices for use in heavy material.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention, as defined by the appended claims.
What I claim as new and desire to protect by Letters Patent of the United States is:
1. In a hydraulically operated power means, the combination of a circular wall and cylinder body forming the confines of a large cylinder, a piston in said cylinder, an upper end wall and a lower end wall forming a hollow space in; said piston of a substantially large diameter for receiving of a force transmitting fiuid therein, a substantially smaller diameter cylinder mounted in the circular wall and having an open end projecting into the hollow space, said smaller cylinder rigidly secured to in said large cylinder, at smaller piston and rod mounted to slide within said smaller diameter cylinder, said smaller piston in its respective cylinder having its head end exposed to the open end and to the hollow space.
2. A combination according to claim 1 and means rigidly and concentrically securing said small cylinder to said large cylinder.
3. A combination, according to claim 1, wherein said piston space is substantially filled with hydraulic fluid, and said large piston is reciprocable within the inner periphery of said large diameter cylinder.
