CORN HUSKER.

' Application filed April 29, 1922. Serial no. 557,413.

- an improved tool of this character having means whereby the grip or handle. portion may be readily and. positively adjusted to various sizes.. Another object is to provide a tubular hand grip in a tool of this class and a further object is to provide an improved device which will be self supporting upon the hand of the husker entirely independently and free of all straps, gloves and other apparatus of a similar nature such as are commonly used in attaching or holding such tools to the hand.

Other objects and advantages will be apparent from the following specification, taken in connection withthe accompanying drawings, wherein one form of the invention is illustrated. I

In the drawings Figure 1 is a plan view of a husking pin constructed in accordancewith the presentinvention;

Fig. 2 is a side elevationof the pin, partly in section;

Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2; 7

Fig.4 is a sectional view,,also taken on the line 33 of Fig. 2, but'showing the movable portion of the handle in position to be adjusted;

Fig. 5 is a rearelevation of the tool; and

Fig. 6 is a fragmentary side elevation of modification. j

Referring more particularly to the drawings, the husking pin is shown of sheet metal construction, and comprises the rolled longitudinally extending staff or handle element 10, the latter terminating at one end 1n an outwardly and laterally projecting husking finger 11, and an outwardly and downwardly curved guard 12. Carried on the handle portion, and longitudinally adjustable thereon, when in a certain position, is a second guard 13, the latter terminating at its inner end in a elongated sleeve or collar 13 circumferentially corrugated, as at 13*; The handle portion 10 passes through the sleeve 13*, the latter together with the guard being longitudinally adjustable upon said portion. The longitudinal edges of the sleeve are spaced apart, as shown in the drawings, in orderto provide for the passage therebetween of a plurality of bosses or lugs l0 struck upon one side of the handle portion.

In assembling the two parts of the tool theguard 13 is slipped over the outer end of the handle portion 10 and moved inwardly thereon, so that tlielugs 10* are received between the edges of the sleeve. The guardis then turned a half revolution upon the hairdle portion, during which the bosses engage the corrugations 13 and serve to hold the guard against longitudinal displacement, except that a slight longitudinal movement is permitted at the end of said half turn to lock the two members against rotation. This locking is preferably elfected by a small recess 13 communicating with each of the annular grooves 13". The slight longitudinal movement referred to draws the bosses or lugs 10 into said recess 13, thereby preventing relative rotation of the two parts.

This locking against relative rotation may be accomplished in various other ways. j For example, the recess might be'replaced by holes in the sleeve. or holes might be provided" both in the handle 10 and the sleeve, through which a small pin might be inserted. A further alternative-would'be indentation, holes or notches in either the handle or the sleeve and struckup lugs in the other part so that one might snap into the other and'resist turning when in use, the parts being disengagedpby twisting them with suflicient pressure, which pressure would not be applied when the husker was inuse; A further alternative is the provision of a wire, parts of which would engage the slit in the tubular member and other parts engage the spaced apart edges ofthe sleeve, thereby locking against rotation. As will be appreciated, the

guard may be adjusted at any time by merely sliding the two parts toward each other a fraction of an inch, and rotating one of them half a revolution in order to disengage the sleeve from the lugs or bosses, thus leaving the guard free to be moved in either direction along'the tubular portion until the desired position of adjustment has been reached, at which time a half revolution 0% the guard upon the tubular portion and a slight longitudinal pull serves to lock the same again in its adjusted position and against displacement. a

The construction shown in part in Fig. 6 is the same as that shown in Figs. land 2, except that the recessesi3 are omitted. It is preferred in practice to construct the lugs or bosses 1C of such size that they engage the corrugations 13: with considerable friction, so that the guard in its various positions of adjustment will be substantially rigid.

As will be observed irom the drawings the front guard 12 curves outwardly and rearwardly' from the pin, while the rear guard 13 curves outwardly and forwardly therefrom. These guards, as wiil be appreciated, are' designed to receive the hand of the operator and, by reason of their configuration, serve to support the pin .on the hand, even though the latter should be open. In other words, no actual gripping of the device is necessary to maintain the same in operative position. In the form of device shown in Fig. 6, the two parts may rotate on eahh other slightly when the device is bein "used without danger of their becoming isengaged and ulling apart longitudinally. In practice t e guards are relatively adjusted to accommodate the hand of thehusker, and so that when applied to the hand the pin will be held transversely thereof along substantially the line defined b the bases of the fingers. If desired, eacli guard may be apertured adjacent its outer end, as shown at 12" and 13 respectively, so that a lacing of some sort may be employed across the ends of the guards as a further precaution against displacement of the pin while in use. A further feature is the provision of the cutting edge or notch 13 in either side of the guard 13. The edge is protected from accidental contact with other objects by the restricted mouth of the notch. The usefulness of thiscutting edge will readily suggest itself to those skilled in the art.

Although I have shown and described my invention as being embodied in certain preferred forms, it will be understood that I do not desire to be limited thereto unduly. On the contrary, I contemplate all proper changes in form, construction, and arrangement, the omission of immaterial parts, and the substitution of equivalents, as circumstances may suggest or necessity render expedient.

I claim- 1. A tool. of the class described comprising a tubular handle portion, a husking point, an outwardly and rearwardly curved guard, all of integral sheet metal construction, and a. second guard rotatably and adjustably mounted on said handle portion.

2. A tool of the class described comprising a hande portion, a husking point, an outwardly and rearwardly curved guard, a sec ond guard carried by said handle portion, and means whereby the same may be adjusted longitudinally and laterally thereof.

3. A tool olf the class described compris ing a handle portion, a husking point, an hutwardly and rearwardly curved guard, a

second guard carried by said handle por tion, said guard terminating in a corrugated sleeve at its inner end, said sleeve ad ustably engaging said handle portion, and means carried by said handle portion for engaging the corrugations ofsaid sleeve to prevent displacement.

4:. A tool of the class described comprisinca handle portion, a husking point, an outwardly and rearwardly curved guard, a second guard carried by said handle portion, said guard terminating in 5. corrugated sleeve at its inner end, said sleeve adjustably engaging said handle ortion, means carried byl said handle FONS/10H: for. engaging the corrugations of said sleeve to prevent displacement, said guard being capable of longitudinal adjustment with respect to said handle portion upon rotation of said sleeve -a fraction of a revolution.

5. A tool of the class, described compris ing a tubular handle portion, a huskin point, and a plurality of outwardly curved guards for engagement with the hand of the husker for holdin the tool in operative position thereon, one of said guards being adjustable both longitudinally and laterally with respect to the other.

6. A tool of the class described comprisin a tubular handle portion, a huskin J polnt, a plurality of outwardly curve guards for engagement with the hand'of the husker for holding the tool in operative position thereon, and means associated with one of said guards to permit adjustment of the same upon relative rotation of said last named guard and handle portion.

7 A husking pin comprising handle portion a guard, a husking point at one end thereof and a second guard rotatably mounted on said handle portion adjacent the other end thereof.

8. A husking pin comprising a handle portion, a husking point and a guard rotatably mounted on said handle portion, the mounting of said guard being such that the same may be adjusted both laterally and longitudinally to accommodate the hand of the husker.

9. A husking pin comprising a handle 5 portion, a husking point, a guard rotatably mounted for lateral adjustment on said handle portion and means whereby said guard may be adjusted longitudinally of said hanagainst longitudinal movement upon return L thereof.
