@In .tgehnlt tratta tu in that ttttets that no mating wat nf tigt tame.

Be it known that I,.JAY NOBLE, of the city of Rochester, county of Monroe, and-State of New York, have invented a new and useful instrument or machine knownA and entitled the Motive-Power Lever, to be used in moving or propelling railroad engines and cars, and other heavy movable objects,vby hand-power, tc.; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, makinga part of this speciiication, in which4 i Figure 1 represents ahand-lever, about six feet long, with a slit or opening perpendicular through the same, as shown in'g. 1, from letter d to d, with thre'e horizontal holes through the same. at letters a a" a", und through which bolts are inserted, to hold jacl -head 2 and fulcra 3 and 4in their place.

igure 2 represents a short fulcruln or jack-head, which is to be placed against or under the object to be moved, which is also held by bolt a, and which can be raised or lowered as occasion may require.

Figures 3 and 4 represent two fulcra, about three feet long, extending from lever 1 to the iron rail or ground below, with crotches at the bottom, as shown at letters ff.

Figure 5 represents a chain or rope attached to ignQ at the eye c, and connecting with the car A, or other object to be moved at letter e, for the purpose of holding the jack 2 to its place.

Figure 6 represents a section of an iron rail of a railroad track, upon which fulcra 3 and 4 rest. Letter A shows partof a car to be moved, against which fulcrum or jack 2 restsfor presses. v

The operation of the machine is as follows: When placed in position, as above described, the operator takes hold 0`f the lever 1, at or near the small end, and presses downward. This, by force of the power created' by lever 1 and fulcrum 3, necessarily drives forward fulcrum or jack 2, which carries with it the object against which it rests; and as the small end of lever 1 goes down, fulcrnm L rises and` moves or swings forward, and when lever 1 is raised, fulcrum 3 is raised with it, and moves or swings forward in like manner. Thus, by moving'thc small end of lever 1 steadily up and down, like a pump-handle in the'act of pumping, the object to be moved, by means of jack 2 and fulcrum 3, is kept in constant motion by the motive power of this machine. A eur may be prevented from 'running back, or braced, by means of jack 2 and fulcra 3 and 4, which, when the lever 1 is not in' motion, act as a prop or stanchion. The jack 2 and fulcra 3 and 4 may be lengthened orshortened by use of the holes b and the letters a a am, andthe crotches may be slight or deep, as use maydictate. The instrument or machine may be constructed of wood, iron, steel, brass, or other metal.

The object of my invention is to move heavy bodies, such as loaded freight or other cars by the useot this hand machine, which may very properly be styled a one-man power. Claim. I

What I claim as my invention, and desire to secure by Letters Patent, is- The lever 1, jack and fulcra 3 and 4, constructed and arranged as and for the purposes mentioned and set forth.

JAY NOBLE.
