IM PROVEMENT I HAY- ELEVATO Spccification forming part of Letters Patent No. 27,899, dated April 17, 1860; Reissue No. 1,341, dated Scptember'), 1862.

To all 'whom 'it may concer'n:

Be it known that I, F.'F. F'OWLER, of Crane township, in the county of Wyandot and` State of Ohio, have invented certain new and useful Improvements in the Construction of Elevators for Hay, &c.; and I do hereby declare the following` to be a full, clear, and' ex- 'act description of the same, reference being had to the accompanyingdrawings, making a part of this specification, in which- Figure l represents a perspec ive view of the machine as in use.

To make a hay-elevator so simple and perfeet as to become a regula-r agricultural implement requires much skill and invention. In the first place it must be cheap and simple; secondly, it must be portable, easily placed, and stanch enough to endure the work without the use of guys or braces that have to be set, arranged, or fastened; thirdly, the base of the elevator must not be so broad or long as to interfere with its being brought up close to its work.

The object of my invention was to embrace all these desirable qualities inone apparatus, and this, I believe, I have effectually done.

My invention consists, first, in the combination of the permanent pyramidal supportimg-frame and the revolving or turning crossbar and its braces with a central supportingpiece for steadying and allowing the cross-bar and its braces to turn freely upon the supporting-frame and it further consists in combining with the cross-bar revolving upon an under supporting-frame, the so arranging of the hoisting-tackle as that the weight to be raised shall be upon one end of the crossbar while the power to raise it is applied to the opposite end of the cross-bar, so that a small structure may be used that can be conveniently transported or moved, will occupy but little space, and be sufficiently stanch without the addition of guys or braces that require fastening or adjusting; and it further consists in the construction of elevators for hay of two pyramidal frames, one placed upon the other, the under frame being upright and the upper one inverted, the apices of both so united as that the upper frame may freely turn upon, while it is supported by, the lower frame.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawing.

If. the baseA of the elevator could be made large enough, the structure would stand without liability to topple over; or, if guys or extra braces were used, the structure could Vbe made rigid by them, but a large base prevents the' machine from being readily and closely moved up to its work, and also prevents the hay from being brought up close to the machine, so thatthat feature is quite objeetionable. i

To: use extra guys or braces from the top of the structure would not only interfere with the free turning of the cross-bar, but the ytrouble of fastening and unfastening them every vtime the structure had to be moved would prevent the general use of the machine. To get, therefore, a small base and obviate the use of guys or braces, I so rig the hoistingtackle as 'to make it subserve the purpose of guys or braces, and so equalize the load upon the structure as to make it abundantly rigid without any other support than its permanent support on its base.

From thev base A rise braces B, which point to a common center, their upper ends being framed into or secured to a head-bloclg; and a post, D, centrally placed between the braces, may rise up to or through said headblock, which post may be additionally braced as at E F. These pieees B, O, D, E, and F together form a pyramidal frame supported by and resting upon the base A.

B is a cross-bar projecting both ways from the central support or post, D, and suflicientl y -far to admit of the hay beingpeasily caught upon the fork and raised 'up or transferred to the stack. From this cross-bar braces H H incline inward to and' are secured to a head-v block, I, that rests upon the head-block O, or upon a shoulder formed upon the central support, D, or partiall y upon bot-h, but so that the cross-bar and its braces may freely turn thereon when necessary to do so. The pieces G, H H, and I form a second pyramidal frame, but inverted, and its apex, I, rests upon or is so connected with the apeX (J of the lower pyrarnidal frame, through the central support, D, as to allow the upper frame to freely turn on while it' is supported and guided by the lower frame. Sheaves a a are placed in or on the ends of the cross-bar G, over which the rope b is reefed, one end of said rope passing around a sheave, c, in a block, (Z, that is hooked to the base A at any convenient point; and to this' end of the rope the team or power to raise the hay is connected or attached. To lthe other end of the rope a is connected, by chains or ropes, e, a fork, f, having a series of prongs or teeth, g, slightly curved, upon which the hay to be elevated is supported; i To the handle h of the fork is attached a line, i, which the attenvdant holds in his hand while the hay is being elevated, allowing it to slip through his hands under suitable restraint until the hay is to be dropped from the fork, when he releases or lets go the line i, and the fork will then draw out of the hay or other thing being 'stacked or housed.

By thus suspending the weight to be raised at one end of the cross-bar and applying the power to iraise that weight at the opposite end i of the cross-bar the tendency of either to topl cross-bar G to overbalance is taken by the brace on that side to the head-block I, or to the central supportingpost, where it is counteracted, and thus by a coniparatively small base, and without fastening the apparatus to the ground by guys, braces, or anchors, it is sufficiently rigid and firm to resist any overturning, while from its lightness and portabilityit is with ease moved from place to place, as may be required. The strength of the under frame is concentrated in its head-block or apex O. The tendency of the cross-beam Gr to overbalance is sustained by its head-block or apex I, and thus both the strength and the strain come upon each other at a central point, Where it is easily poised or disseminated.

The machine may be placed on Wheels or runners for the purpose of easily moving it from place to place, and two or more staclrs may be built without changing its position, as

object of my invention, what I claim thereinj as new, and desire to secure by Letters Patent,

1. In the construction of elevators for hay. the combination of the permaneut pyramidal supporting-frame and the revolving cross-bar and its braces, with a central supporting-piece for allowing the cross-bar and its braces to turn upon the supporting-frame, substantally in the manner and lfor the purpose described. 2. ln the construction of elevators for hay, in combination with the crossbar revolving upon an under supporting-frame, the so arranging of the sheaves and hoisting-tackle as that the weight to be raised shall be upon one cnd of the cross-bar, while the power to raise that weight is applied to the opposife end of the cross-bar for the purpose of enabling me to use a small and compact structure that may be easily transported or moved, occupyin g but little space, and sufficientl y rigid within itself without the use of additional guys, braces, or other fastenings, as herein described and represented. 3. In the construction of elevators for hay, two pyramidal frames, one placed upon the other, the under frame being upright, and the upper one inverted, and the head-blocks or apices of both so united as that the upper framemay freely turn upon while it is supported by the lower frame, substantially in the manner described.
