COMBINED FORK AND RAKE.

SPECIFICATION forming part of Letters Patent No. 768,769, dated August 30, 1904.

Application filed April 6, 1903. Serial No. 151,420. (No model.)

To all whom it may concern.-

Be it known that I, CAsPAR PRANGEMEIER, engineer, a subject of the King of Prussia, Emperor of Germany, and a resident of No. 41/42 Katthagen, Munster, in the Empire of Germany, have invented a new and useful Combined Fork and Rake, of which the following is a specification.

The present invention relates to an improved implement which can be used either as a fork or as a rake.

The combined fork and rake serves principally in Woodcraft and agriculture and in making roads.

Special objects of the invention are to simplify and cheapen the construction and to render more efficient, serviceable, and durable in operation devices of the kind referred to.

With these ends in view the invention consists in the novel combination, arrangement,

and adaptation of parts, all as more fully hereinafter explained, shown in the accompanying drawings, and then specifically set out in the appended claim.

As an example of carrying the invention into practice, Figure l of the drawings is a plan view of the improved implement. Fig. 2 is an inverted plan view of the implement. Fig. 3 represents a longitudinal section of the implement, and Fig. 4 shows a detail of construction.

On the wooden shaft a is secured a metal tube 1), which is fitted at its upper end with screws-threads c, as is shown in Fig. 4, or with a transverse bore (Z for the reception of a bolt 0, as shown in the remaining figures. The end of the metal tube Z) projecting beyond the shaft (.4 carries on a pin f rotatably the fork g. In order to render the fork g adjustable, the external end of the metal tube 1) is slotted at it. On the opposite side of the tube 6, but not extending to the end of this tube, a second slotz' is provided. The fork g abuts at the outer edge of the slot 71 when assuming the position illustrated in Fig. 3. On the metal tube 5 is movably mounted a guide-tube k, which can be fixed in its working position either by a screw-nut Z, fitting on the screw-threads c, or by a bolt 6. The bolt 6 can be inserted in a transverse bore in the shaft a either in front of the guide-tube it or through holes in same. A screw-nut may be employed to secure the position of the bolt 6. Instead of the said-bolt e a bifurcated pin may be utilized. A short chain can serve for securing the means employed to the guide-tube'lc. The end of the tube 5 projecting beyond the shaft or is provided with holes to for the reception of the bolt n in a direction corresponding to that ofthe pivot For adjusting the implement as a fork the fork g is turned around its pivot f from the position shown in Fig. 3 to the position illustrated in Figs. 1 and 2. This movability of the fork g is rendered possible in View of the slots hand o'. It is obvious that the length of the slot 2' must be chosen so as to enable the head portion of the fork g to take up room in the tube 6. The bolt a is then pushed through the holes on in the tube 1) and through a bore previously provided at the proper place in the head portion of the fork g. By virtue of the two bolts f n the fork g is rigidly secured in its position. The guide-tube is is then pushed along on the tube Z) until the screw-nut Z or the bolt 6 can be fixed .in connection with the shaft (0, as hereinbefore described.

To use the implement as a rake, the screwnutZ or the bolt 6 is removed, the guide-tube is pushed backwardly, the bolt n removed,

and thereupon the fork g is turned to assume I the position shown in Fig. 3. After fitting again the bolt 01, in the holes m and pushing the guide-tube is along the metal tube 6 until either the screw-nut Z or the bolt 6 can secure said guide-tube Is in its position the fork g will be rigidly secured, as the head portion of prising in combination a shaft a, a metaltube Z2 secured thereon, a fork g rotatable on a pivot f, supported in the slotted front end of the aforesaid metal tube 12, a bolt 71, a pair of holes mfor said bolt 7 inv the tube 6 corresponding in position to a bore in the head portion of the fork g and a movable guidetube is on the tube 6, adapted to be fixed in regardv to the shaft a to secure the position of the fork g asarake, substantially as described and shown.

In Witness whereof I have hereunto signed my name, this 22d day of November, 1902, in the presence of two subscribing Witnesses.

(JASPAR PRANGEMEIER.
