Lesers Patent No. 62,647, dated March 5,1867.
IMPROVEMENT IN HOISTING APPARATUS.
iige'rlgetub referat tu in tigen ettersrztmt mit making met nf tige sans.
To ALL wHoM rr MAY ooncsnn.
, Be it known that I, A. It. LEMEN, of Kalamazoo, in the county of Kalamazoo, and State of Michigan, have invented a new and improved Hoisting` Apparatus; and I do hereby declare'that the, following is a. full, clear, and exact description thereof, reference being had to the accompanyingdrawings, forming part of this `speci` iication.
Y The nature of my invention consists in constructing an apparatus so that greatweights may be raised by tho application of a small amount of power. It more particularly consists incon'structing and arranging a series of gear-wheels, in combination with a frame to which the said gear-wheels are attached.
' To enable others skilled in the art to make and use my invention, I will proceed to describe its construc- I tion and operation, in which- Y Figure l represents an end elevation of my improved hoisting apparatus; and
Figure 2 is a top plan view of the'same. Y
Letters of like name and kind refer to like parts inthe figures.
vA A may represent four inclined posts framed inte two parallel timbers B'B, the said posts and timbers being of suitable dimensions for the purpose. Upon the top of the said posts A. are framed crosstimbers or beams C C, strengthened and supported byiinelined braces D D. E E are two short posts erected upon the timbers B B, at the top of which are secilred two cross-timbers or beams F F, one of which is iirmlysecured upon each-side of the posts Eso as to leave a space between the two timbers the width of the two posts., Gr G are two straight horizontal braces connected to the tops of the posts E E and the cross-timb'ersor beams F F, which extend, and are secured to lthe posts A A, for the purpose of supporting and adding strength tothe posts and beams before described. Hill' are two beams which extend'out in a horzontai direction from the posts A, a short distance above whcrejbeams or bracesG G connect to the said posts. To these said beams H H are firmly framed two cross-beams I I. .I J are two strong timbers or bars framed to the cross-beams-or timbers F F, which project outside of the timbers or beams F F for the purpose of forming a bearing for the crank-shaft L, upon whichA is the pulley K. This pulleyiK is for the purpose of winding -a rope, to which a team is attached to operate the apparatus.' Y Y are two girths framed to the posts A A, running parallel with the bottom timbers B B for the purpose ot' supporting the framework. Upon the outer end of the'crank-shaft L is a bevel pinion-wheel, M, that meshes into a corresponding bevel gear\vheel, N, that is secured and turns with shaft O, the said shaft O having suitable bearings P P upon the beams F F. Upon the opposite end of the said shaft 0,from the bevel-wheel N, is a small pinion, Q, (tig. 1,) that meshes into and turns a corresponding spur-wheel, R, which is firmly secured to the shaft S, that isprovided with and runs in suitable bearings I.I, which are located and secured near the centre of the cross-beams or timbers I I. At th'e opposite end of the shaft S, from the spur-wheel R, is another small pinion-wheel, a, fig. 1, that ts and'meshes into a corresponding wheel, T. This said wheel T is rigidly secured to a strong shaft or axle, U, that is provided withiand runs in bearings e e, the said bearings being located andsecured upon the main cross-beam or timbers C' C. Around the said shaft or axle U works the chain or rope V, the purpose of the said rope or chain being to 'attach to the weight designed to be raised by the machine. i is a small pin located-in and passing through the crank-shaft L, so as to form a shoulder against the bearing` while the machine is in the act of raising a weight. When it is V desired to llower the chain rapidly, the pin i is withdrawn from the crank-shaft L, which will allow the pinion Mito become disengaged from the bevel-wheel N; the chain will then run down fast, and while the pinion M is out of gear, the end of the chain V may be raised rapidly by means of the pin -w in the wheel R.
The operation of this apparatus is easy and powerful. The machine or apparatus is placed over the body or object -to be raised, and the chain V attached thereto, when, by'tnrning the cranli L or drawing a rope around the pulley K, puts inmotion the wheel R, whichtransmits a reduced motion to the wheel T, through the medium of the pinion a, which is attached to the shatt or axle U', upon which winds the chain V. If it is desired to stop the vmachine while elevating a weight, the pawl w, that works in the teeth of the wheel R, will hold the `weight suspended. When the weight is raised, andlit is desired to lower the chain rapidly, by removing lthe pin from the shaft L allows the pinion'hiV to slip out of mesh with the wheel N, and the chain to run down; an"v f when it is desired to wind theehain up rapidly around the shaft or' axle U, by turning the wheel R, by the'pin n, it is reaily woun up, making it one of the cheapest, most powerful, and convenient machines ever used for hoisting purposes. l 4
Having thus described my invention, what I claim.as new, and desire to socmje .by Letters Patent, is lhe combination and rrangement of the geavfiwheels, as shown and described, in combinationwith the frame, when constructed substantially as descibed mid for the purposes sei; forth.
A. R.l LEMEN.
