SPECIFICATION formingpart of Letters Patent No. 759,421 dated May 10, 1904.

Application filed January 26, 1904- Serial No. 190,686. (No model.)

To all whom, it may concern.-

Be it known that I, JEROME A. CROSS, a citizen of the United States, residing at Fulton- .ville, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Apparatus for Unloading Hay, &c.; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for unloading hay, grain, &c.; and theobject of the invention is to produce an extensible track which is adapted to project through an opening in a building and afford suitable means supporting hoisting mechanism, whereby hay or other commodities may be raised and conveyed to a stationary track inside the building, the extensible mechanism being so arranged that when desired the same may be swung into the building under shelter, thus leaving no parts of the apparatus exposed to the elements and dispensing with the projecting hoisting supports which are at present commonly employed and which frequently become impaired and necessitate replacing.

More specifically, my invention comprises an extensible track, which is hinged to a permanent track supported by suitable hangers within the building and so arranged that when it is desired to adapt the apparatus for use the extensible track may be hoisted so that one end thereof will project through an opening in the building, and when thus ad justed the extensible portion of the track will be in alinement and continuous with the stationary track.

My invention consists,further, in various details of construction and in combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, which with the letters of reference marked thereon form a part of this application and in which drawings similar letters of reference indicate like parts in the several views, in which- Figure 1 is averticalsectional view through a portion of a building, showing my extensible track in elevation in solid lines and in operative position and dotted lines in the position it assumes when drawn within the building. Fig. 2 is a perspective view showing the hinged connection between the extensible track and the stationary track. Fig. 3 is a detail View of a clevis member.

Reference now being had to the details of the drawings by letter,A designates the beam, which may be of any suitable material and supported by cross-pieces B within the building and which is provided for supporting the stationary track C. Said track has eyebolts D passing through the same and nuts D, carried upon the threaded shank portion of said eyebolts, which engage the stationary track 0 upon its upper and lower faces, while the eyes of said bolts engage the eyes E of the screws E, which pass into and engage the beams A. Mounted adjacent to the end of the stationary track is a yoke member F, which is held to the supporting-beam A by means of a clevis member K, and the arms F of said yoke are adapted to overhang the opposite faces of the track U and are secured thereto by means of bolts or any other suitable fastening means, as shown clearly in the detail view of the drawings. A portion of each arm of said yoke projects beyond the end of the track and is adapted to receive the end of the extensible track H when the latter is hoisted to a horizontal position in alinement with the fixed track in readiness to support the hoisting apparatus. Said extensible track H has a yoke N, the arms of which pass through the track and are held by means of the nuts 1 and pivotally mounted on a pin 0, carried by said yoke member, is a clevis member O,,which is adapted when the extensible track is hoisted to a horizontal position to engage over a hook Q, which is integral with the plate or bar Q, fastened, by means of bolts q, to the cross-piece I, which is fastened to the building, (designated in the drawings by letter J.) The upper end of the plate or bar Q is bent to form a hook Q upon which a sheave or pulley R is supported. A rope M is fastened at one end to the brace-rod H, which has an eye at its outer end engaged by a bolt 71/, passing through the extensible track, while its inner end h is bent at an angle and passes through the inner end of the track and is engaged by a nut mounted upon the threaded end of said rod. By the provision of said rod H the strain coming upon the extensible track will be equalized and means afiorded whereby the track may be raised or lowered by power applied to the rope M, which passes over the sheave or pulley R.

In order to facilitate the engagement or the disengagement of the clevis O with the hook Q, without the necessity of an operator going above, I provide an eye Q which is made integral with said clevis member and through which the hoisting-rope M passes, whereby as the track is hoisted the clevis will be held by the rope passing through the eye integral with the clevis adjacent to said hook, and by simple manipulation of' the hoisting-rope by the operator said clevis may be easily caught over the hook and the extensible track held in an operative or working position. When it is desired to disengage the clevis from the hook, the extensible track is hoisted a slight distance to allow the clevis to clear the hook, and bymanipulation of the hoisting-rope the clevis may be swung clear of the hook and the extensible track allowed to fall by gravity to assume the position shown in dotted lines in Fig. 1 of the drawings.

The inner end of the extensible track is bolted or otherwise secured to the hinge 'I, one portion of which is fastened by suitable means to the end of the fixed track, and when the extensible track is raised to a position in alinement with the fixed track the arms of the yoke F will engage over the meeting ends of the fixed and extensible tracks and allow any suitable carriage to pass back and forth over the hinged ends of the tracks without any interference.

By the provision of my improved apparatus, it will be observed that a simple and efiicient means is provided for holding an extensible track in an extended and operative position projecting through an opening in the building and affording a support for hoisting mechanism for unloading any commodity and transferring the same to the fixed track, and by the provision of the apparatus embodied in my invention the extensible track may be easily and quickly withdrawn into the building, thus preventing the subject-ion of the apparatus to.

the action of the elements.

WVhile I have shown a particular construction of extensible-track apparatus embodying the features of my invention, it will be understood that I may make alterations in the detailed construction of the device, if found desirable, to meet various conditions Without in any way departing from the spirit of the 5 invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a fixed track mounted within a building, an extensible track having hinged connection with the stationary track, means for raising said hinged track into alinement with the stationary track, and mechanism for supporting the extensible track in its working position, with one end thereof projecting through an opening in a building, as set forth.

2. In combination with a fixed track mounted within a building, an extensible track hinged to said fixed track, afixed supporting-bracket, a yoke carried by the track, and means for hoisting the extensible track into alinement with the fixed track, and mechanism connecting said yoke with said bracketarm, whereby the extensible track may be supported in a working position with one end thereof projecting through an opening in the building, as set forth.

3. In combination with a fixed track held within a building, an extensible track hinged to said fixed track, a yoke carried by said track, a clevis pivotally connected to said yoke, a sheave and means for supporting the same, a fixed hook, a hoisting-rope passing about said sheave, and connections between the same and said extensible track whereby the latter may be hoisted into alinement with the fixed track and said clevis brought into engagement with said hook, whereby the extensible track may be held in a working position with one end projecting through an opening in the building, as set forth.-

4:. In combination with a fixed track mounted within a building,an extensible track hinged to said fixed track, a stationary bracket-hook, a yoke secured to the extensible track, a clevis pivotally connected to said yoke, an eye projecting. from said clevis, a sheave supported above said bracket-hook, a rope with connections between the same and said extensible track, and adapted to pass through said eye upon the clevis, as set forth.

5. In combination with a fixed track, a yoke member secured to the end thereof, and means for supporting the same, the arms of said yoke projecting beyond the ends of the fixed track, an extensible track hinged to the end of said fixed track, and means for raising the extensible track into alinement with the fixed track with said yoke-armsprojecting over the meeting ends of the two tracks, and supporting mechanism for holding the extensible track in a raised position, as set forth.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

JEROME A. CROSS.
