STACKING-V'IACHINHE.

srnciEIoATIoN' forming part of 'Letters Patent No. 621,630, dated March 21, 189e.

Application filed September 14, 1898. Serial No. 690,964. (No model.)

To all whom', it may concern: l

Be it known that I, RODDY O. OOBLE, of Marion, in the county of Marion and State of Kansas, have invented a new and Improved Stacking-Machine, of which the following is a full, clear, and exact description.

The object of my invention is to construct a hay-stacker in a simple, durable, and economic manner and so that it may be swung from side toside of a support or raised or lowered with ease and despatch.

Another object of the invention is to construct a hay-fork that will maintain a horizontal position while being raised and lowered and provide the fork with a lock or latch that will act to hold the fork horizontal.

A further object of the invention is to provide a trip for the fork-lock and operated from the ground, which lock when operated upon by the trip will permitthe fork to incline sufficiently to properly dump its load.

Another object of the invention is to provide a locking device for the swing-support of the fork, whereby the fork can be held in loading position, and, furthermore, to provide a releasing device for said lock that may be operated from the ground.

The invention consists in the novelv construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart otthis specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved machine, the fork being in position to receive its load. Fig. 2 is a similar view to Fig. 1, except that the fork is shown elevated from the ground, and in this. position also the dumping position of the fork is illustrated. Fig. 3 is a plan view ofthe device, showing the fork in positive lines at the side of the base where it is adapted to receive its load vand in dotted lines at the side of the base where the load is to be discharged. Fig. 4 is a detail view of the releasing device for the locking mechanism of the swing-support for the fork,

and Fig. 5 is a detailperspective View showing a part to be fully described hereinafter.

A base A is provided, which base is mounted upon wheels or upon runners,s0 that it may be readily moved from place to place.` An upright B is mounted upon the said base, pref'- erably near one corner, and the said upright is shown as strengthened by braces b. At the upper side surface of the upright B an extension h is constructed, and withinthis extension a guide-pulley 10 is mounted to revolve, and at the front of the extension, near the outer side, a vertical friction-roller 11 is mounted in suitable bearings, the vertical roller being nearer the outer side face of the extension b than the guide-pulley 10. A post 12, adapted as a support for the hay-fork O, is mounted in suitable bearings 13 and 14 at. the front lower portion of the upright, as shown best in Figs. 1 and 2.

A cross-bar 15 is carried from the upright B to the side brace b, and in a pocket in said brace a guide-roller 16 is mounted to revolve, and beneath the said cross bar a double drum 17 is mounted to turn on the base. A rod or a bar 18 is secured to the pivoted post 12 at its inner face, and the said rod or bar is carried inward, terminating in a handle, and near the handle end of the rod or bar a gravity-latch 19 is mounted, adapted for engagement with a keeper 20, as shown in Figs. 3

and v4. The la-tch 19 is released from the keeper through the medium of a pin 21, which is made to extend upward through the base, as shown in Fig. 4, and through the keeper, the pin being pivotally attached at its lower end to a foot-lever 22.

The fork O consists of a series of teeth 23, upwardly curved at their rear ends, the end teeth being provided with extensions 24, carried from the back portion in direction of the front to form guards', as shownv best in Fig. 1. The teeth or tines of the fork are connected near their centers by a rod or a bolt 25, which extends from one side of the fork to the other, the tines being held properly spaced by sleeves 26, located on the said bolt. Asecond bolt 27 is passed through the upper portions of all of the tines, and this upper bolt is likewise provided with spacing-sleeves 28, as shown inA Fig. 3. Supporting-arms 29 and 30 are pivoted upon the bolt 25, one at each side of the center, being held in suitable position by spacing-sleeves, and the said arms 29 and 30 are preferably made to converge at their inner ends, and said inner ends are pivotally attached to the upper portion of the pivot-post 12.

A lock C' is pivoted upon the upper rear bolt 27 of the fork at its center, and the said lock consists of a shank 32, which is connected directly with the fork, and a body portion 34, the said body portion being curved and provided with a longitudinal slot 35, and at the forward portion of the slot 35 a vertical extension 36 of the said slot is formed, as shown in Fig.2. An angle-lever 37 is fulcruined at the junction of its members upon a pin 31, which is passed through the supporting-arms 29 and 30 for the fork, the lever being held in suitable position on the said pin by sleeves 33, as shown Ain Fig. 3. The upper member of this lever is preferably provided with a slot which extends through to l the upper end, while the lower portion of the lever or that portion below the pivot -pin 3l is usually solid. The body portion 34 of the lock C is passed through a slot in the upper portion of the lever 37, and a pin 38 is likewise passed through the upper end of the upper portion of the lever 37 and through the slot 35 in the body of the lock C, as is best shown in Fig. 2. The lowerend of the lever 37is pivotally attached to two links 39, one being located at each side of the lever, and the links 39 are pivotally attached at their inner ends to opposite sides of the pivot-post 12, near the bottom portion of said post.

A releasing-lever, comprising a shank 40 and a head 41, is adapted to throw the lock C upward, carrying the pin 38 from the eX- tension-slot 36 when it is desired to dump the load froln the fork. The head portion of the releasing-lever is pivoted in the slotted portion of the angle-lever 37 just below the lock C', and the head is of such shape that when the shank 40 of the lever is drawn inward the head of the releasing-leverwill force the body portion of the lock C upwardly. The releasing-lever is operated through the medium of a cord or chain 42, attached to its shank portion and led rearward, through an eye 43 on the upright, preferably to a point near the handle of the rod connected with the pivot-post 12.

A cable or chain 44 is attached to the upper portion of the upright B, the said cable or chain being passed over the pulley of a block 45, which block is pivotally connected bya bail 46`with the supporting-arms 29 and 30 of the fork. The cable or chain 44 is carried from the block 45 at the rear of the roller 1l and over the guide-pulley 10, thence downward over the guide-pulley 16 to the drum 17, the drinn being attached in any approved manner to any suitable source of power.

In the operation of the machine when the fork is to receivea load the said fork is carried to the lower position (shown in Fig. 1) at the front of the machine, and when the fork is in this position the pin 38,carried by the anglelever 37, will have entered the extension-slot 36, so that the fork is held from turning, yet as the fork :is carried upward after receiving its load the tines of the fork will maintain a horizontal position throughout the movement. This is due to the pivotal connection between the lock C and the fork and likewise the pivotal connection between the angle-lever 37 and the lock and the angle-lever and the links. When the fork has received its load, it is raised to the desired height through the medium of the chain or cable 44, and when the proper elevation has been reached the operator presses downward on the foot-lever 22, which forces up the latch 19, connected with the post l2, releasing said latch from its keeper, whereupon the fork is swung over, usually by hand, to the side of the machine, as shown in dotted lines in Fig. 3, the elevating rope or cable 44 working against the roller 11.

When it is desired to dump the load from the fork, the cable 42 is drawn upon, which will cause the head 4l of the releasing-lever to rise, and said head coming in engagement with the lower portion of the outer end of the slotted body of the lock C will raise the said body portion of the lock and cause the pin 3S in the lever 37 to be carried out from the extension-slot 36 and brought in position to enter the main slot 35. At this time the fork automatically dumps itself, being carried to the inclined position (shown in dotted lines in Fig. 2) lby the weight of the material on the fork.

It will be observed that the dumping movement is limited and that the fork cannot dump farther than will be permitted by the length of the slot 35. After the load has been dumped from the fork said fork is carried to the front of the machine through the medium of the bar 18, and when the bar is carried over the keeper 2O the latch 19, which is a gravity-latch, will automatically engage with said keeper. The forkis then lowered to the ground, andupon reaching its lower position the body of the lock C will have been carried so far inward as to cause the pin 33 to automatically enter the extension-slot 3G, thus locking the fork against dumping.

The machine is exceedingly simple and easily operated. It is economic and through its use a stack may be evenly, expeditiously, and conveniently formed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a hay-stacker, the combination, with a swinging post, a fork, arms pivoted to the fork and to the swing-post, and an angle latch-lever pivoted between the said arms, of a lock pivoted to the rear portion of the fork,
