IMPROVEMENT In HAND-ENGINE.

TOALL wHoM IT MAYcONcERrnf y t f i Beit known that we, CHARLES T. ULMAN,.of the city of New York, county of New York, and in the State of'NewYork, and MARCUS Bochum, of the city of Brooklyn, county rif-Kings, and in the State of lNew York, have invented a newand useful'Impx-ovement inHaud-Engnes; and we do hereby declarethe following .tobe

a full., clear, and exact deseription of the same, reference being .had to the accompanying drawings, (three l,

sheets,) making apart of this specification,` in whichp Figurel isl a side elevation. l

Figure 2, aside elevation 4ot' part ofthe hand-engine. .Figure 3, a perspective view of the mein lever. Figure 4, la side elevation of the crank with connectinglevers. Figure 5, au endelevation of part of the engine.

filiali theligures in the drawings the letters of reference' employed denote identical parts. Our inventioneonsists ofthe c onstruction of a hand-engine worked by means of levers, arranged in such a mannery that but little force is required to start and to keep the enginesworking .parts going.

A v To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and operation. A v l p VOur hand-engine consists of two vertical rectangular frames orl standards A, supporting the machinery, and placed far enough from each other toallow the Imachinery to work.- Each frame, A, consists of two parts, a lower and an upper one, well secured toeach other. The lower frames, A, incline towards each other st their upper parts,1spreading outat the base in order to 'give a stronger rest for the upper frames A.' Both frames are placed in a parallel .position towards each other, and well securedto each other with braces, &c. B is a triangular peceand used as a. crank or quarter crook/At its lower points C itlis 'attached to arms C, as shown. in figs. 1, 2, 4, and I The shai't N, which4 rests in bearing'N on the upper part ofthe lower frames A Aforming a right angle with the frames, projects over both frames,`. and at each of its ends supports a wheel, M, which may be used as a ily-wheel. At each end, and betweenV the lower frames, a meinA` lever, E, is Vhung -on a bolt or pivot, E, by

4means of arms D and C.1 The lever E is connected with thecrank ZB.

When the machine is not worked, the main leverE will't occupy a vertical position, as shown in iig, 1, and lig. 2 shows Vthe lever E in an inclined position At'its lower endfthe lever' E is provided with al projection,

forminga right angle with the 'shaft of the lever E. The size of, this projection or weight will "determine the power. By increasing or decreasing thesize or weight of said4 projection the power will beincreased or decreased. The main lever Eis at-its upper part, a little below the pivot'EQ-provided with ajont, E', which might be useful in case the engine were placedon any swimming-surface'. The joint or hinge E, shown in iig. 3, will Vallow the lower part of the leverV to swing sideways, and'in such .case the frames A mustbe put far enough'from each other, and so constructed thatthey do not interfere with the motions of the lever E. In gs. 2 and 3 another shape of lever E is shown than in fig-1.

Thelever E is actuated by arms L L, which are pivoted at E" to minor arms E E', securedto the upper part of levers E E. The connectng-rods or arms L arc atl their upperends provided -withslots L' L', in which l ebelt or pin, I, moves; the bolt I resting in socket. E, which is `irmly attached to the lower point of a frame or workingbeem, G. This frame is constructed like a'rhomboid; its sides are curved outwards, and proyided p withl slots G Gr'. The working-beam G is at its upper point pivoted to the vertical upper frames A A', where it hangs suspended, and allowed to oscillate when worked upon by levers H.

i 4The handles K, by whichv the engine is worked, are pivoted to the upper part of the vertical frames A A' at K', and at their upper parts provided with arm I,as shown in fig. 1. This erm I projects towards the inner p pnrtlof the machine, and has points `I', which work in slots H".

H H are levers of a triangular form, pivoted near each other in the upper part of the vertical frames A',

a little below the pivots K. Friction-rollers lI" and H are secured in arm I, insuch a manner that it touches the upper face of lever H and frame G. At' their lower ends the levers H are provided with a rectangular projection, in which a pin, H', is inserted, and said pinsl H working inslots G.

. `When-the arms K are moved up and down', the machinery is put in motion, the movements of the arms K will communicate an oscillating motion to the levers lH, and the motion through pins H working in slots G',

will actuate upon the working-beam G. Arms L- connected through the socket F will, when said socket com mences to oscillate, also he put in motion, and thereby working the main levers-E. Thus worked upon, the levers E will, through the agency of arms D and Crevolve the crank B, andthe axle und ily-wheel M thereby put in motion. K

We do not confine ourselves to the precsemode of construction ofour improvement, nor the particular use; but *A I What we claim, and desire to secure by Letters Pstent, is 1. The combination of handles K, projections I, levers'H, working-beam G, socket E, and arms L, when arranged as and for the purpose set forth. Y l i l 2. The main lever E, when constructed as and for the purpose set forth. l 3. The combination of arms D and C; and the ltriangular,crank or quarter-crook B, when arranged as and for the purpose set forth. A v Y.
