` ."lhcllwhom it mayconcem: Y

Be it known that I, JACOB It. FnrrznoUs,

i of Indiana,.in the county of Indiana and State of Pennsylvania, have invented la new and valuable Improvement in Hay-Elevators; and I do` hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had `to the annexed drawings making a part of this specification, and to the'letters and figures of reference marked thereon.V Y

Figure lof' the drawings is a representation` of ila 4sectional view ot my hay-elevator, rand Fig. 2 is a sideview of the same.V Fig.

3 is a detail view. n

This inventionlhas` relation to devices which aredesigned for; elevating hay from wagons, and delivering the loads upon mows in barns', wherein the elevating-fork is attached to a .pulleyl suspended from a carriagewhich-is movable on abar `or beam located at or near the `top 'of the barn, so. that when a load is ,raised to the proper height it can be easily `moved `to a place for discharging it. Then'at're of my invention V consists 11n the novel construction and arrangement of the Parts, @Slll'enafter more fully described andclaimed. i l

. L, In the 'annexedw"drawing,- A A' designate 7 .the roof-timbers of a barn, to Which are secured the endsof around bar, B, which I denominatethesupporting-bar, as it is `upon this bar th atthe carriage of the elevator travu els.'` C desigratesthe carriage, which isoi` triangular ibr`mtl'1e upper angles ofthe trian` gle being 'connectedtogether by means of two rods, whichserve as axles for two deeplygrooved wheels,a `a.' vThese wheels a a roll` i upon theba-r B, and allow the'carriage-fraine `b to' be swunglaterally Vwithout any liability .of

the said wheels being detached from their i bar. The lowerpart oi' thecarriage C carries a groovcd pulley, c, around which an elevating-rope, `g, p`asses." One end of this rope `g e is secured to the fra-me b of the carriage U,

I and the other end of the'rope -may be passed over a pulley, p, located Vat or near the rooftimber` A'. From this rope is"suspe1nled a l l pulley-block, h', carrying a pulley, p, and hav-V ing secured to its-lower end a l|ook,., to'which is attached a forkof suitable description, with a tripping device for it. E designates a stirrup, which is pivoted at c to one end of wa le; ver, D, and which hangs freely from this lever, so as to always assume such a position that, when the load is raised to its fnll height, the said pulley-block h' will raise the stirrup E, and with it one end of the lever D. This lever D is pivoted at i to anA oiset of the frame adaptedto engage with a catch, G, which .is adjustably secured tothat end of the bar B fromfwhiohthe load is elevated from awagon. This catch Geisthe half of a concave conethat is to say, it is tapering from a concave i base, and laterally convex-and presents av semicircular catching-lip, j. The catch thus described is securedA to a teat or stop, k, by means of n'uts and bolts, or bolts alone, which are lettere-dm m in Figs. 2 and 3. `The stop k presents a `concave edge, j, towardthe ear"- riagc C, and this stop isr so arranged, kwith refer- .ence to the catch G, that the carriage will be varrested by said stop k at the same time the hook f engages with this catch.-

It will be seen from the\ above description 'that the catch G, being .laterally rounded,

will allow the hook fof lever D to engagewith it whatever may be the angle of inclination `given to lthe carriage C. Also, that the carriage is arrested by a stop,fk, whenthehook fengages with the catch G.'

l The catch and stop, thus made separately, 'and connected together, can be easily adjusted on the supporting-bar 'to any point or position by simply loosening the bolts. 'i It will be furthermore seen that the lever D serves not only to hold the carriage V in its proper positionwhile the load is being elc- .\atccl, but that'when the load is elevated to its highest point, and the pulley-block i'vtrps' the rope and prevent thedescent of theload.

t saidlever, it (the leierl D) will vdrop upon the Y rope g, and', by its toothed portion d, gripe Heretofore it has been customary to permanently seeurethe catch and stop to the barnbeum, for engagement withthe hooked lever of the movable carriage but my improvement consists in constructing the catch andstop in two'separate and movable pieces, ybolted to gether around the beam, whereby they can be.

easily adjusted yand removed without interfering with the barn-beams or the operation of the carriage. t o

=Wha-t I claim as new, and"A desire to secure by Letters Patent, is-

:rne adjustable. ana removern catch e, n periug' and laterally rounded, and having a lipped` bese, and which -is separately con structed from the wheel-stop k, and applied to bar B, and secured thereto by meansv of boltsand nuts passing through the stop. k and catch G, in combination with a hooked clutching-1evere D, substantially as described.

In testimony 'thatI claim the above I have 'hereunto subscribed my name in the presence `Nifitnesssesr GEORGE Row,
