VALENTINE L. NEY, OF CANTON, OHIO, ASSIGNOR TO THE V. L. NEY COMPANY, 0F CANTON, OHIO, A CORPORATION 0F OHIO.

HAY-ELEVATOR.

To all whom it may concern.'

Be it known that- I, VALENTINE L. NEY, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Hay-Elevators, of which the following is a specification.

My invention relates to improvements in hay elevators of the cross draft type for elevating and conveying hay and the like and more particularly intended to be used in conveying hay and other material from a wagon to a hay mow or other` place of deposit.

The objects of my invention are, first, to provide a suitable overhead track or way upon which is to travel a carriage or frame; second, to provide means whereby the load can be held suspended atany desired point between the starting point of elevation and the extreme height or limit of elevation; third, to provide means to relieve the track from a direct horizontal lateral pull during the time the load is being elevated from the wagon to the desired point of elevation. I attain these objects and others by the construction and manipulation of the various parts illustrated in the accompanying drawing, in which- Figure l is a side elevation of the upper carriage member or frame showing the same mounted upon a track or way and an end view of the lower or suspended member of the carriage or frame. Fig. 2 is aside elevation of the lower carriage or frame member and an end view of the upper carriage or frame member, the track being shown in transverse section. Fig. 3 is an enlarged view similar to Fig. 2 showing parts removed and other parts broken away, the parts being shown in position to release the load. Fig. 4 is a detached perspective view of the rope grip.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, l represents the track or way which may be of the usual twin-rail form or of any other desired form, reference being had to the proper mounting of the traveling carriage upon the track or way. It will be understood that this track or way is to be suspended preferably from the rafters of a barn or like structure; but in as much as the track and the Specicaton of Letters Patent.

manner of suspending the same forms no specific part of the present invention, the devices commonly employed and used for suspending tracks of this nature are not illustrated. The upper carriage frame 2 is substantially of the forni shown in the drawings and as shown it is provided with suitable bars 3, to which bars are journaled the traveling wheels 4L, the peripheries of which traveling wheels are formed to fit upon the tread portion or portions of the track or way. The side members of the upper'carriage frame 2 are provided with the downward extended plates 5, which are preferably formed integral with the upper carriage or frame. The plates 5 are tied together by means of the short cross bars 6. rIhe lower carriage or frame consists eccentrically of two side plates 7 which side plates are spaced apart a suflicient distance to provide room for locating the various operative parts of the carrier.

The side plate 7, together with the dierent parts connected to and carried by said side plates are pi'votally connected to the upper carriage frame by means of the bolt 8 or its equivalent, which bolt is located below the track or way l and substantially parallel with the length of the track and is so located for the purpose of allowing the lower carriage frame to swing or move laterally to a perpendicular line laterally with reference to the track or way so that the lower carriage frame or member can swing laterally with reference to the track or way.

It will be understood that in cross draft carriers the pull upon the elevating rope during the time the load is being elevated is lateral to the track or way, but by providing means whereby the lower carriage member is permitted to swing laterally the direct horizontal lateral pull is removed owing to the fact that when the lateral pull is taking place the lower carriage member is free to come in substantial alinement with the angularity of the elevating rope 9 or in other words the cross draft and the resistance of the load being elevated is equalized to a great extent by reason of the lower carriage member moving from a perpendicular position to an inclined or more specifically to an angle to a perpendicular line. The elevating rope 9 is secured in any convenient and well known manner to the lower carriage frame, said elevating rope being preferably at tached to the cross bolt 10 or more specilically to the sleeve 11 located upon said cross bolt 10.

rlhe elevating rope 9 extends downward through the elevating heads 12 or their equivalents, which elevating heads or blocks are provided with ordinary pulleys, said elevating rope thence extended upward over and upon the circumterentially grooved pulley 18, which grooved pulley is properly journaled upon the cross bolt 14E, which cross bolt is located substantially parallel with the length of the track or way 1, by which arrangement the pulley is located at substantially right angles to said track or way. The elevating rope extends from the pulley to the proper point where power is to be applied, which is usually horse power; that is to say the usual means are provided for hitching a horse or horses to the elevating rope 9. lt will be understood that the pres ent invention has no reference to the particular manner ot operating the elevating rope.

For the purpose of assisting in holding the elevating rope 9 in proper relative position with reference to the pulley 13, the pulley 15 is provided, which is properly journaled upon the cross bolt 16, said cross bolt being held by suitable apertures formed in the arms 16a, which arms are preferably formed integral with the side plates 7. Between the side plates 7 is located the rock bar 17 which rock bar is pivotally mounted upon the cross bolt 18, said cross bolt being properly connected to the side plates 7. 'llo the bottom or lower portion of the rock bar 17 is pivotally connected the rope grip actuating arms or ngers 19, which lingers are spaced from each other and normally located upon. opposite sides of the faces of the pulley 13. The arms or fingers 19 are tied together and held in proper relationship with reference to each other by the integral head 20, which head is provided with the ears or tlanges Q1, said ears or lianges providing means for pivotally connecting the arms or fingers to the rock bar 17 by a suitable cross bolt 22. The side faces of the pulley 13 are provided with a series of pins which pins are located near the periphery of said pulley and are for the double purpose hereinafter described. To the top or upper end of the rock bar 17 is pivotally attached the link 24;, to which link is pivotally attached the rope grip 25, said rope grip being curved longitudinally, the curvature corresponding or substantially corresponding with the curvature ot the wheel 13 or in other words, said rope grip is substantially concentric with the pulley, so that the entire length et the rope grip can be utilized to clamp the elevating rope as hereinafter described.

lt will be understood that the contact face of the rope grip should. be concaved as illustrated in Fig. et and .is so termed ior the purpose ot better gripping the rope. 1t will. be understood that during the time the load is being elevated, the elevating rope will impart rotary motion to the pulley 13 and during the time rotary motion is imparted to the pulley 13 the pins 23 will come under the fingers 19, said .lingers resting upon the pins. 1t will also be understood that during the time the load is being elevated the top portion of the pulley will move to the right or in the direction indicated by the arrow Fig. 3. For the purpose ot automatically holding the rope grip Q5 out ot frictional contact with the elevating rope during the time a load is being elevated, the weighted arm 26 is provided, which weighted arm has a tendency to rock the roel; bar 17 in the direction to move its top or upper end away from the pulley 18 and carry with it the rope grip 25. The outer i'ree end of the rope grip during the time the load is being elevated lies loosely upon the elevating rope but in such a manner that it does not interfere in any way with the movement of the elevating rope during the time av load is being elevated. Then a load has been elevated to any desired point and it is desired to hold the load in elc vation the pull upon the elevating rope is released, thereby permitting the load to descend by its own weight a short distance, at which time the pulley 1? rotates in the opposite direction from that during the time the load is elevated, or in other words a bachward movement is imparted to said pulley. As the pulley 13 moves backward one set or pair of the pins 23 will engage the shoulders 27 termed upon the fingers 19 and as the pulley 13 moves backward, said tingers will be moved in the direction of the movement of the pulley which moves the bottom or lower end ot' the rock-bar 17 away from the pulley 13 and forces the top or upper end of said rock-bar toward the pulley, which movement forces the rope grip 25 upon the elevating rope 9, thereby gripping the rope between the pulley and the grip rope, which gripping prevents the further descent et the oad.

1t will be understood that the load can be held at any point ot elevation between its starting` point and the extreme height or upward limit of the load, owing to the fact that by releasing the pull upon the elevating rope 9 the elevating rope will be automatically gripped as just above described, regardless ot' the suspended position of the load. 1t in the event it is desired to lower a load the rope grip 25 is released by a down pull oi the weighted arm ZG by means of the trip rope 28, whiclntrip rope is extended downward to a point of suitable access. 1t will be understood that during the. time the rope grip 25 is being brought int-o position to grip or clamp the elevating rope, the weighted arm y 26 will be elevated at its outer end as illustrated in dotted lines Fig. 3, which elevation takes place by means of the rocking movement imparted to the rock bar 17.

For the purpose of preventing the rope grip 25 from moving' upon its pivotal point when pressure is brought upon said ropegrip to grip the rope the link 24 is provided with the foot 29, which foot is extended over a portion of the rope-grip 25 and presses upon the outer face of the rope grip when the rock-bar 17 is moved in the direction to clamp the elevating` rope 9. For the purpose of moving the carriage back and forth upon the track or way either for the purpose of conveying a load or to bring the carriage directly above the point from which a load is to be elevated the pull ropes 30 are provided which are preferably connected to the rings 3l, which rings are preferably connected to the short cross bars 6 by means of the connecting fianges 32. It is immaterial as to the specific manner of connecting the pull ropes 30 to the carriage proper as the only purpose is to so connect the pull ropes that a direct pull can be given to the carriage. it will be understood that the pull ropes 30 are to be extended to any desired point of suitable access.

The pins 23 or their equivalents should be so spaced from each other that one or more of said pins will lie under the arms or fingers 19. so that at no time said fingers will be permitted to fall by, gravity into such a position that the pins or their equivalents will not come into proper contact with the shoulders 2T or their equivalents. For the purpose of preventing any of the pins 23 from passing above the upper free end of the fingers 19 the outer ends of said fingers are curved upwardly or provided with the upward curved ends 19a.
