JOHN C. FREES, OF FERItY, MICHIGAN:

PITCHIFORIL.

To all whom it may concern:

Be it known that I, JOHN 0. Farms, a citizen of the United States, residing at Ferry,

in the county of Oceana, State of Michi an, have invented certain new and useful mprovements in Pitchforks; 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 tomake and use the same.

This invention relates to attachments for pitchforks and is more particularly designed for use on forks for loading or pitching ma-i nure.

The object mview is to provide an attachment of such nature that the material gathered up by the fork may be readily removed therefrom and this by the ordinary back ward pull usually given a fork of this character as it is removed from the wagon box into which the material is b'eing loaded.

In carrying out my invention, I provide upon the handle of the fork a lever which is freely movable and connect to this lever, the rear ends of legs or rods which are provided at their forward ends with collar portions which fit over the tines of the fork and are movablealong the same.

will result in the lever striking the edge of the wagon box into which the material is being loaded and will force the legs forwardly todischarge the manure from the fork.

In the accompanying drawings, Figure 1 is a perspective view showing the manner of using the fork, Fig. 2 is.a top plan view of the fork with the attachment in lace thereon, Fig. 3 is a side elevation of. t e forkand the attachment, Fig. 4 is a front view thereof, Fig. 5 is a vertical sectional view through one of the tines of the fork showing in full lines the normal position of the corresponding leg and in dotted lines the position of the leg when the attachment is operated to discharge the manure, and,'F1g. 6 is a detail sectional view through the pivot bolt for the legs showing the manner in which they are connected with thewhandle.

As shown in the drawings, the fork is of the usual construction including the usual handle 7 and the tines 8 which latter may be of any number desired; r I

A pair oft'rip lever bars 9 are connected at Specification of Letters Patent. Application filed August 9,- 1907. Serial Noas7,seo.

The backward pull given to the fork as above mentioned Patented July 28, 1908;

pivot bolt 11 which is passed through the connected with the handle. The legs "here- 'tofore mentioned are indicated by the numeral 12 and formed at the rear end of each their lower ends to the handle by means of a of the'said legs is an a ertured ear l3. 7' A pivot bolt 14 is passed t rou h the said ears and throughthe upper ends 0 the levers 9, it being understood that an equal number of legs are disposed, upon each side of the said "levers. At their forwardends, each ofthe said legs is pivoted to a collar It's-which is fittedover the correspondin tine'z8, the said said edge of the wagon box and the levers he fork is then given l 0 The manner of using the fork is as follows: 7

will be swung forwardly moving the legs in a;

corresponding direction andcausing their collar portions to shove any adhering material from the tines of the fork. v

It will be understood that when the device is applied to a fork having five tines, the leg for the middle tine may be pivoted between the upper ends of thelevers 9 wardly of the same.

What is claimed, is p The combination with a itchfork including a handle and tines, of a pair of levers pivoted at their extreme lower ends to the handle at opposite sides thereof and projecting upwardly therefrom in parallel relation, a bolt engaged through the extreme upper ends of the levers and extending to opposite instead of-out f sides thereof, le s formed with spacing 001- JOHN L. RIENVUS, E. -L. BENTON.
