HAY-LOADER.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed June 4, 1904. Serial No. 211,099-

To a whom, it may concern:

Be it known that we, JoEL R. OHNSTAD and MIoHAs L. OHNsTAD, citizens of the United States, residing at Morrisonville, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Hay-Loaders; and we 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.

Our invention relates to hay-loaders, and has for its object to provide certain improvements in this class of machine with a View of securing increased efficiency.

To this end our invention consists of the novel devices and combination of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like notations refer to like parts throughout both views.

In the said drawings, Figure 1 is a vertical longitudinal section through the entire machine with some parts broken away, and Fig. 2 is a plan view of the machine with some parts broken away.

The numeral 1 represents the supportingwheels, and 2 the axle on which the said wheels are loosely mounted.

The numeral 3 represents a skeleton frame adapted to support the working parts of the machine. At the lower end of the frame is suitably journaled a shaft 4, and at the upper end of the frame is suitably journaled a shaft 5. On the shaft 4 directlyinward of the side bars of the elevator-frame are located a pair of sprockets 6, and on the upper shaft 5 a corresponding pair of smaller sprockets 7, on which sprockets 6 and 7 is mounted a toothless loading-conveyer 8 of the chain, slat, and rope type. On said lower shaft 4 directly inward of the sprockets 6 are located another pair of sprockets 9, which cooperate with" a pair of sprockets 10 on a shaft 11 to support a toothed pick-up conveyer 12 of the slat-andchain type. The sprockets 6 and 9 on the lower shaft 4: for supporting the two conveyers are of the same size, and the shaft 11 is solocated and its sprockets 10 of such size that the said sprockets 9 and 10 so support the pick-up conveyer 12 that it will run, together with the loading-conveyer, through the rake-arc and for a limited distance lengthwise of the elevator-frame, and, further, that the teeth of the pick-up conveyer will work through the face of the loading-conveyer, as may be clearly seen in Fig. 1 of the drawings.

A guard-deck made up of suitable longitudinal thin slats 13 and cross-bars 14 is suspended by flat springs 15 from the top crossbars of the main frame 3 between side bars 16, rigidly secured to the top cross-bars of the said main frame. The guard-deck, made up of the said parts 13, 14:, and 15, is thus yieldingly mounted and held by its springs 15 in position to hold the hay on the face of the loading-conveyer 8, and because of its construction and mounting the guard-deck will yield as an entirety and its longitudinal slats 13 will spring or yield individually, so that the entire deck and all its parts will adapt itself to the hay on the face of the loading-conveyer. This guard-deck is of a length to extend upward beyond the delivery end of the loadingcon veyer 8 and downward and backward beyond the receiving end of the same to points between the tines of the gathering-rake 17. The rake 17 is pivoted to the lower top crossbar of the main frame and connected by link 18 to a spring-pawl hand-lever 19, pivoted to a lock-segment 20, for raising and lowering the rake and holding the same in any desired set position in the usual way.

A pair of drag-bar shoes 23 are fixed to the horizontal part of the main frame 3 and extend backward to points beyond the working.

position of the rake 17 and serve to prevent undue backward pivotal motion of the loader and to prevent the outward spread of the gathered hay beyond the outer end tines of the rake.

A pole-tree 24 is pivoted to the axle 2 and provided with a bolt 25, adapted to secure the same to the underlying cross-bar 26 of the main frame 3 when the hay-loader is in Working position, as shown in Fig. 1. The forward end of the pole is bifurcated in the horizontal plane and fitted with a spring-pressed hook 27 for coupling the hay-loader to a link or ring on the rear axle of the hay-rack truck. (Not shown.) ,When the machine is to be idle or stored in a shed or barn, the bolt may be removed,thereby permitting the hay-loader frame to be turned down on the axle 2 into a horizontal position parallel with the pole.

On the axle 2 are loosely mounted a pair of the hay rack.

large sprockets 28, connected by chains 29 with small sprockets 30, fixed to the projecting end of the lower conveyer-shaft 4E. The sprockets 28 connect by slip-ratchets 31 with the hubs of the ground-wheels 1. Hence under the forward motion of the machine the ground-wheels 1, through the driving connections marked 28 to 31, inclusive, will impart rotary motion to the conveyer-shaft 4C, and this in turn will impart motion to all the supporting sprockets and shafts of the two conveyers 8 and 12.

With the construction and disposition of the parts as above described it is obvious that under the forward motion of the machine the hay will be gathered by the rake 17 and be picked up by the teeth of the conveyer 12, working through the face of the loading-conveyer 8, and will be carried up thereby underneath the yielding guard 13 foraconsiderable distance along the frame of the elevator or until the pickup conveyer begins to turn downward over its driving-sprockets 10, leaving the hay on the conveyer 8. The loadingconveyer 8 will then carry the hay on upward underneath the yielding guard-deck and deliver the same from the top of the loader into (Not shown.) The upward projection of the guard-deck prevents the'hay from being blown off from the top of the loader when being delivered to the hay-rack to be loaded.

From the fact that the loading-conveyer 8 is toothless it follows that the hay will be de livered therefrom to the rack without any tendency on the part of the conveyer to drag the same back downward with its under-running fold.

By actual practice we have demonstrated the efliciency of the hay-loader herein disclosed for the purpose had in view.

It will be understood, of course, that details of the construction may be changed without departing from the spirit of our invention.

What we claim, anddesire to secure by Letters Patent of the United States, is as follows:

1. In a hay-loader, the combination with an elevator-frame, gathering-rake and toothless loading-conveyer, of a toothed pick-up c0n-,

veyer with its supporting-surface, mounted to travel with the loading-conveyer through the rake-arc, and in the same plane with said JOEL R. OHNSTAD. MIGHAS L. OHNSTAD.
