To all whom it may concern: Be it known that I, FRANCIS M. TINSLEY, a citizen of the United States, residing at Blakesburg, in the county of \Vapello, State of Iowa, have invented certain new and useful Improvements in Hay-Stackers; and I do hereby 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. This invention relates to hay stackers and has'for its object, primarily, to provide, in a hay stacker, means whereby the stacker head will be swung automatically, in a horizontal plane substantially to the extent of a half circle when it is elevated to a predetermined height. More specifically it is the object of my invention to provide a stacker comprising an upright frame or standard, a stacker head movable vertically along said upright or standard, and a pull rope for elevating said stacker head, the pull rope being provided at one point in its length with a button or collar which, when the pull rope has been drawn sufiiciently to raise the stacker head to a predetermined degree will engage with a means which is operable by reason of such engagement to swing the stacker head and its supporting standard or upright substantially to the degree of a half circle so that the head may be loaded to one side of the base of the stacker and its load discharged to the other or opposite side thereof. Another object of my invention is to'provide a stacker of this type comprising an upright or standard, a guide frame mounted to slide vertically upon said standard, a hay platform or head fixed to the guide frame, and means for holding the guide frame in an upright position, the means being releasable to permit tilting of the guide frame and at the same time of tilting of the hay platform or stacker head. In the accompanying drawing, Figure 1 is a perspective view of the stacker the stacker head being in intermediate position, Fig. 2 is a front elevation thereof, Fig. 3 is a side elevation showing in dotted lines the relative positions of the parts of the stacker head prior to tilting thereof and in full lines the position of the parts after the stacker head has been tilted. Fig. 4 is a vertical transverse sectional view through the lower end Specification of Letters Patent. Patented Feb. 16, 1909. Serial No. 415,9-=4=. of the upright of the stacker and through the base upon which the said upright is sup ported, and, Fig. 5 is a horizontal sectional view taken directly above the lower cross head of the upright. In the drawings, the stacker is shown as comprising a base indicated in general by the reference character A, an upright inclicated in general by the reference character B and a stacker head indicated in general by the reference character C. The upright B is in the form of an open frame comprised of stiles 6 which are parallel and spaced and which extend vertically and are divided at corresponding points and substantially at a pointequidistant from their ends as at 7 and hinged at their point of division, there being hooks 8 provided for holding the stiles elevated, it being understood that the hooks may be manipulated to permit of the stile sections being folded one upon the other. The frame comprising the upright also includes an upper cross piece 9, a lower cross piece 10, an intermediate cross piece 11 and crossed braces 12. A is preferably box-like in form including sides 1%, ends 15 and a top 16 which extends partly across the upper end of the otherwise open base. A hollow frusto-conical standard 17 is supported in a stationary manner upon the top 16 and is formed at its upper end with a ball race 18. Secured upon the under side of the cross piece 10 of the upright frame is a pulley 19 which is held spaced from the said cross piece by means of a block 20 interposed therebetween and the said cross piece and the said pulley and block are formed with a frusto-conical stem 21 for the reception of the standard 17 there being a ball race 22 fixed within the socket at the upper end thereof and ball bearings 23 disposed in this ball race and in the ball race 18 formed in the upper end of the standard. In this manner a very substantial support is afforded for the upright frame and one which permits turning of the frame with respect to the base the function of which movement will be presently fully described. Upon the upper cross piece 9 of the frame there is fixed a stud 21 which has a swivel engagement in the center of a triangular head 22' to the corners of which head are connected the upper ends of guide cables 23, these cables being stretched taut and connected at their lower ends to stakes, The base which are driven into the ground at proper points. it will be understood from the foregoing that the upright frame is supported, by reason of the construction described, vertically for turning movement. The stacker head or hay platform as it may be termed comprises tines 24 and cross pieces 25 which latter are preferably two in number and receive between them the stiles of the upright frame. This head comprising the tines and cross pieces as above described is supported by means of a guide frame made up of uprights 26 which project upwardly from one cross piece 25, to a cross piece 27 which connects the upper end of theruprights and braces 28 which are secured at their outer ends to the outer ends of the cross pieces 25 and at their inner ends to the ends of the cross piece 27. Two of the tines 24 are indicated additionally by the numeral 24 and these tines have their rear ends extended rearwardly beyond the rear cross piece 25 as indicated by the numeral 29 and pivoted at their lower ends to the said rear ends 29 of the tines are arms 30 which are held by means of spring 31 inclined in the direction of the stiles of the upright frame, the upper ends of the arms 30 being connected by means of a rod or shaft 32 from which, adjacent to the upper ends of the arms 30 are j ournaled rollers 33 which travel along the rear edges of the stiles. Latches 34 are pivoted as at 35 to the arms 30 adjacent the upper ends thereof and these latches have their forward ends headed and shouldered as at 36 and engageable with the cross piece 27 to hold the head in raised or horizontal position, this engagement of the latches with the cross piece being maintained by means of springs 37, which connect with the latches forwardly of their pivots and with the arms 30 below the plane of the latch pivots. Rollers 38 are journaled in suitable brackets upon the front cross piece 25 and are designed to travel along the forward edges of the said stiles of the upright frame and it will be understood from the foregoing that as long as the latches 34 are in engagement with the cross piece 27, the head will be held raised or in other Words in horizontal position and on the other hand it will be understood that when the latches are disengaged from the cross piece, the heads will be allowed to drop or tilt as is very clearly shown in Fig. 3 of the drawings, there being a cross bar 35 connecting the latches forwardly of the stiles 6 and the rope 39 connected to the cross bar at its middle and passed over the rod 32, this rope serving as a means whereby the latches may be disengaged from the cross piece 27 in unison. A bail 40 is connected to the cross piece 27 and attached to the bail at the middle thereof is a block 41 there being another block 42 suspended beneath the upper cross piece 9 of the upright frame of the stacker. A pull rope or cable 43 is passed in the usual manner through these blocks and is extended downwardly and through the hollow upright 17 and into the base A of the stacker, being passed downwardly under a pulley 44 within the said base and through an opening 45 formed through one end 15 of the base. Mounted for rotation upon the top 16 of through aslot 52 formed in a partition 53' depending from the said rear edge of the top and through the slot 45 heretofore mentioned and being provided at its outer end with a swiveled guide eye 54 through which the cable is passed. Normally the arm and bar are in the position illustrated in full lines'in Fig. 5 of the drawings and when in such position, the tines of the stacker head are presented forwardly from the stacker but when the cable has been drawn out sufficiently'to elevate the stacker head to the proper height to be dropped for the purpose of discharging the hay supported thereby, an abutment, button or collar 55 upon the cable 43 will engage with the guide eye 54 of the bar 51 and pull the bar into dotted line position shown in Fig. 5 resulting in a partial rotation of the pulley 47 and in a rotation of the pulley 19 to the extent of 180 degrees. This rotation of the pulley 19 will result in a like rotation, and to a corresponding degree, of the upright frame B of the stacker and of course the head carried thereby, thereby bringing the head in such position that its tines will be directed rearwardly and in the proper direction for discharge. The rope 39 may then be pulled to disengage the latches and permit dropping or tilting of the hay platform or heat. What is claimed, is i 1. A hay stacker comprising an upright frame, a stacker head movable vertically upon the'said frame, a pull rope for elevating the stacker head, the said head being tiltable, means whereby the head may be released for tilting movement, a pulley arranged at the base of said frame and having connection with the frame whereby rotation of the pulley will result in a turning of the frame, an arm connected with the pulley, a guide carried by'the arm, and a button carried by the pull rope and engageable with the guide to swing the arm and rotate the pulley when the head has been elevated to a predetermined height. 2. A hay stacker comprising an upright, a stacker head mounted for vertical sliding movement upon the upright, the said upright being mounted to turn, a pulley having operative connection with the upright whereby rotation of the pulley will turn the upright, a pull rope for elevating the stacker head, an arm operatively connected with the pulley, a guide carried by the arm through which the pull rope passes, and a button carried by the pull rope and engageable with the guide to swing the arm and rotate the pulley thereby turning said upright when the stacker head has been elevated to a predetermined height. In testimony-whereof I ailix my signature, in presence of two witnesses. FRANCIS M. TINSLEY. Vitnesses JOHN LA F OLLETTE, S. C. SNOW.
