To ALL WHOMIT MAY coNoERN; i y y Be it known thatl, S. E. TUTTLE, of Genoa, in the countyoilDouglns',` undv Stcteof Nevada', have invented e new and improved Machine for, RnisingHeavy Weights; and I do hereby declare t-ht'the following is c full, 'cleuigand exact description thereof, n'hich willenahle' others skilled in the nrtto ineke und use 4the sume, refer.
.ence being hed to the accompanying drawings, forming pert of this specification, in which* HFigure 1 is u longitudinal section of vui'y improved machine' taken through tholinea: :c,"`g. 2.
Figure 2 is a. front viewof lthe same. Similar -letters of reference indicate like parts. My'nvention has for its ohjectto furnish-'an improved machine hy meansof rihch heavy weights may he: raised with a, comparatively small outlay of power; and it consists in an improved mchine formed by the combinationofthe shaft, the wheel having 'a' spiral groove formed in itsfsce, the .toggle-blocks hving frction- -rollers attsehedfto them, and the slide,`or equivalent, to'whi'ch they are pivoted with euch other :mdwith thc guide-posts and frame'of the machine.
A is the frame of the machine, which must hcfmsde of s strength proportionedto the weight of thel objects to berssed or to the powerto be exerted by said mztchine. B is n shaft, revolving in bearings, C, uttachedto the top of lthe frame A. To oneend of the shaft B is attached a. pulley,` D, or geur-Wheel by-whichpower is applied to`the shaft B. To the other end of theshuft is attached the 'wheel E, having ejspiralgroove, e, out
'in it'sfce, and running from neer-the centre tothencireumference ofL said wheel., The dimensions the wheel lEwill depend upon the particular use to which themaehine isl to-h-e nnplied,`butlfor ordinary purposesI usually make it about two feet five inches in. diameter. The groove4 el, which, on a wheel of this size, should'he about three inchesrwidmhegins aboutthreeinches'from the/centre nd terminates at lthe circumference of seid wheel. The llange -ehetvreen. the coils of the groove e is about one inch wid e, so that one revolution of the wheel E willrnisethe iveight four inches. F is s. slide,"tha.t 'moves up' anddowfn in grooves formedin the inner sides of jtheguide-posts Gr, securely attached to the freine A'. II arelcast-ilron blocks p ivotedn slotsiu` the slide F.` AThe ends of .the blocks H are hevellecl, as shown in 1, so as to .allow the seid blocks to'sn'ing euward, so as to prevent them fromY passing in too fur, and soith'nt in raising the weight their upper endsfmoy heer against fthesolidpart of the slide F, und rlieve the pivoting-pin 4from the strain. ...Ihre frictiomwheels, pivvcted to the rear side of the"blocks H by bolts passing through'said wheels and blocks, as shown in fig. 1. `Tile wheels I ure of s uoh u., size as'toenter the groove e inthe face'of the 'wheel E, and the wheelsI and .blocks :1re et, t suche. distance 'spartjthat when one wheel. reaches the. highest part of the wheel E, the next one will have entered the groove e :it the-centre of the wheelE." The -wheels I are kept away from the face of the wheel until they have reached the proper'point to-enter the groove el by u llunge, J, a.tta.ched -to thc guide-post G, und
having its'endsinclned, as shown in'g.. f1. 'As-thel slidejE moves upsvard, the ilenge or arm-ft formed upon or uttaehed vto the blocks H, strikes ugainst the flange J', which lifts the seid -hlock arid irheels sway from the wheel' and holds them away until they have re'ztcliedthe proper point for the said' wheel to enter the groove el.- IfA desired, the blocks H may be attachedto au 'endless chain or to a wheel, guides being-used to lreep` the said blocks in proper position with reference to the wheel E; t
What I'claim as new,and desir e to secure by Letters'Pateugisv 1. A n improved machine formbd hy thecombination of the shaft B, the wheel E lxa" z'ii xgu spiral groove, e, formed in its face, the blocks. H having friction-Wheels, I, attached t'o them, and the slide 3i', or equivalent, .with 'euch other, and with the` guides G and frame A, substantially es herein shown, and described, end .for the pur., pose set forth. i
