HAND-OPERATED LOADING`-MACHINE Specification of Letters Patent. Patented NOV. 30, 1920.

Application led April 12, 1919. Serial No. 289,673.

ToaZZ 'whom 'it may concer/1i Y Be it known that I, Enron Enrciison, citi zen of the United States,.residing at Minne-` apolis,in the county of llennepin and State of Minnesota, have invented certain new and useful Improvements in `Hand @perated Loading-Maclii1ies5 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.

My invention has for its object to provide a simple and eiiicient hand-operated loading machine adapted for various uses, but especially adapted for picking up and elevating shocks of hay, bundles of grain and various other things, and placing the same on a rack or wagon.` The device is also ada ated for the lifting of boxesy and the like. he loading machine can be carried on a separate truck or can be applied to the vehicle that isto be loaded. The drawings show the loading machine applied to the rear of a wagon-bed.

Referring to the drawings Figure l is a view chiefly in side elevation, but with some parts sectioned, showing the loading machine applied to a wagon as stated;

Fig. 2 is a plan view of the loading machine, some parts being sectioned; and

Fig. 3 is a front elevation of the loading machine with some parts removed.

The numeral l indicates as an entirety, the wagon to the rear of which the loading machine is applied. The numeral 2 indicates a vertical mast which is bi'fuicated at`3, and at its lower end has a vertical stem 4: that is swiveled in a pedestal 5 rigidly secured toV the bed of the wagon by bolts (i. The nuineral 7 indicates a curved boom or lever which is passed through the bifurcated portion 3 of the mast, and is pivoted thereto at 8. The boom 7 has a handle to swing the same, and the mast, on its vertical pivot 4, and also when the load is not too great, to move the lever to and from the extreme posipions indicated by full and dotted lines in *im l.

pinion l() is rigidly secured to a drum 1l that is free to rotate on a 'stub shaft 12 projecting from a bracketl, that is formed as a rigid or integral part `oit the mast 2. Pinion 10 and drum l1 are held against displacement on stud shaft 12, by pin and washer i4.

gear meshes with pinion 10 and is" ilrce to rotate on astub shaft 16, that projects from another' bracket 17 that is also integral with the mast 2. lin and washer 18 hold gear l5 en the stud shait .1.6. (tear` .l5 is provided with a hand-crank 15a, rigidly secured thereto and. radiating therefrom. A retaining dog i9 pivoted to the mast 2 operates on gear l5, te hold the boom or lever 8 in a raised position.

The numeral 2O indicates a cable, one end oi? which is secured to the drum 1l. and passes over a shcave 2l, which is rigidly mounted to the mast structure 2, but free to rotate, and the other end is secured to the curved boom 7 at 22. The numeral 23 indicates a laterally offset fork-like scoop tor the purpose of handling materials such as hay and the like. The said scoop 23 has an upright extended portion 24k which is pivoted to the curved boom 7 at 25. It will be noted that hooks and coperating chains may be applied to the pivoted portion 25 of the curved boom 7 thus enabling this form of machine to handle materials such as stone, wheelbarrows and the like.

In picking up a bundle or shock of grain or the like, the boom or lever 7 will be swung with the mast on the vertical pivot 4;, so as to shove the` teeth of the scoop 23 in the grain. rlhen the boom will be raised by ro* tation of the crank l5a until the load is brought to the proper elevation, and then the fork may be disengaged from the load by giving the boom a backward swinging movement. This device will be found serviceable in many different things, on wagons and vehicles. The term scoop is used in a sense broad enough to include either a torni of shovel or flat blade. For the loading of hay and the like, the fork will he preferable, but for shoveling up and loading sand, for example, the scoop should be in the form of a shovel.

What I claim is 1. In a loading machine of the kind described, the combination with a mast mounted on a vertical swivel, of a boom pivoted to said mast and provided at one end with a hand-piece, and a scoop pivotally suspended from the other end of said boom and projecting in a direction at right angles to the longitudinal axis thereof.

2. In a loading machine of the kind described, the combination with a mast mounted on a vertical swivel, of a boom `pivoted to said mast and provided at one end with a jecting in a direction atfright: angles to the longitudinal axis thereof, a Windlass drum mounted on the mast, and' a cable attached to said drum, passed over a guide on the Vnppei` portion of said mast and attached to the intermediate portion of said boom.

l 3, In a loading machine of the kind described, the combination with a mast mounted on a verticallswivel, ofra hooin pivoted to said mast and provided aty one end with a hand-piece, a scoop pivotally suspended from the other end ofsaid boom and projecting in a direction at right angles to the longitudinal axis thereof, a Windlass drum mounted on the mast, a cable attached to said drum, passed over a, lguide on the upper portion of said mast and attached to the intermediate portion of said boom, a gear connected to said windlass drinn, another gear Vmounted on the mast and meshingwith the first noted gear, an operating cra-nk connected to the second noted gear, and a lock dog on the mast engageable with one of said gears.

In testimony whereof I ailix my signature in presence of two Witnesses.
