Specification of Letters Patent.

Patented Sept. 17, 1912.

Application filed September 9, 1910, Serial No. 581,212. Renewed February 21, 1912. Serial No. 679,187.

To all whom it may concern:

Be it known that I, JOHN OmsoN VAN CLnAvn, a citizen of the United States, residing at Sidney, in the county of Routt, State of Colorado, 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 loaders.

The principal object of the invention is to improve and simplify the general construction of devices of this character.

A second object of the invention-is to so arrange the hoisting means in a hay loader provided with a pitching fork that themovement of this fork will closely resemble the movement of an ordinary hay fork when manipulated by hand so that the initial raising of the hay is accomplished at a relatively slow speed while the final or discharge movement of the fork is at a relatively high speed.

A third object of the invention is to provide a novel arrangement of hoisting means for such a fork wherein a greater power will be exerted during the initial movement of the fork than at the end of the movement of said fork.

VVit-h the above and other objects in view the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully de scribed, illustrated in the accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a side elevation of a hay loader constructed in accordance with this invention with the fork shown in its lowered position. Fig. 2 is a similar view showing the fork in its raised position. Fig. 3 is a vertical longitudinal section through the hay loader. Fig. 4 is a plan view of the loader. Fig. 5 is a detail perspective view of one of the pivots of the secondary frame forming a part of this invention. a

The loader comprises a main frame which includes a pair of longitudinal skids 10 by which the loader is supported on the ground so that it may be transported from one place to another. At the rear end of these skids are uprights 11 which are connected at their upper ends by a cross beam 12 and the skids are held apart at their lower ends by a cross beam 18. Furthermore the parts are braced by the usual diagonal brace 14. Extending from the upper end of each of the members 11 downwardly and forwardly are which consists: of a pair of spaced triangular frames each of which has a base member 19 and diagonal members 20, the latter having their apical extremities connected to a perpendicular member 21. The members 19 are connected by a bar 22 whereon are fixed plates 23 carrying pintles 24. which engage in the journal bearings 17. This member is arranged in the angle between the members 21 and 19. This triangular frame has its base vertical when the fork is lowered and in referring to the different parts of said frame hereinafter it will be assumed that this is the posit-ion of the frame normally. The upper ends of the base members 19 are connected by a cross bar 25 while the lower ends are connected by a cross bar 26. The verticals 21 extend beyond the apex of the respective triangle and are connected by a cross bar 27. The extremities of these perpendiculars are furthermore connected by a rod 28.

The fork proper comprises transverse members 29 having fork teeth 30 secured thereto and extending forwardly therefrom. These members 29 also support a back rack 31. Attached to the fork are spaced arms 32 which are pivoted upon the rod and these arms are braced to the rack 31 by braces 33.

Extending upward from the members 15 are uprights 34 and diagonal bracing 35 eX- tends horizontally between said uprights and the members 15. Connecting the upper end of said uprights 34 is a bar 36 which is provided with suitable journals so that the bar is pivoted to rotate between said uprights. Extending rearwardly from the bar 36 is a seriesof fingers 37 forming a discharging platform and these fingers are connected intermediate their ends by a mem her 38. Hinged to the extremities of the member 38 are supports 39 which pass through guides 40 fixed to the members 11 and said supports 39 are secured in adjusted relation in these guides by bolts 41. By this means the rear end of the platform may be raised or lowered as desired. Se-

cured to the member 25 intermediate its ends and a second pulley 43 is se- 1 is a pulley 42 cured intermediate the ends of the member 27. Secured centrally of the cross bars 18 is a third pulley rod 28 and centrally thereof is a fourth pulley 45. Secured intermediate the ends of the member 13 is a guide pulley 46. A cable 47 has one end secured to the fork frame 29 and is led over the pulley 42 and pulley 43 around the pulley 44, over the pulley 45, and around the pulley 46 out of the side of the device so that a draft animal may be attached to travel laterally of the loader.

' In the operation of the device the hay gathered on the fork 30 is lifted by stress upon thecable 47 At first the action is to rotate the triangular secondary frame about its pivots until the pulleys 44, 45 and 46 are brought into such alinement that the cable lies straight betweenthe pulleys 44 and 46.- Then the triangular frame ceases to rotate. During this part of the operation the frame.

has been lifted by the cross bar 26 which constitutes a stop member to limit the movement of the arms 32 relative to the frame in one direction. After thisinit-ial movement has been accomplished further stress upon the cable 47 will rot-ate the arms 32 about their pivots until the fork braces 33 engage the member 36 which thus acts as a stop member to limit the movement of the arms rearwardly. By reason of the peculiar arrangement of the cable the initial movement is relatively slow while the final movement is very rapid so that the hay is thrown violently over the delivery platform toward In the returning of the device upon slack-' ing the cable the triangular frame first rotates until the lower ends of the arms 15 are and brought to the rear of the center of gravity. The upper ends of these arms then move out strike the stop member 26 and the triangular frame and fork revolve together to the initial position. There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that many minor changes 44 and mounted on themay be made in the form and construction of this invention without departing from the material principles thereof. It is therefore desired to confine the invention to the exact form herein shown and described but it is wished to include all such as come within the scope of the appended claims.

Having thus described the invention what is claimed as new, is
