This specification discloses a device intended to be used in retrieving pecans from the ground with a pick up action. The device comprises an elongate rod having an open bottom receptacle secured to its lower end. This receptacle has parallel side walls. A spring of general U shape includes side legs and a straight back. The upper ends of the legs are anchored to the side walls on their outer faces and the back spans the open bottom between the lower edges of the sides. A roller is rotatably mounted on the back and is adapted to engage a pecan with a rolling action as the open end of the receptacle is forced thereover.

Nagel, Ser. No. 860,926, filed Sept. 25, 1969 and entitled
PECAN RETRIEVER, now U.S. Pat. No. 3,600,029.
1. In a pecan retriever including:
2. The pecan retriever of claim 1 in which the roller assumes a position centrally of said bottom edges when the spring is free of any deflecting
3. The pecan retriever of claim 2 in which the roller is spaced a slight
4. The pecan retriever of claim 1 in which the roller is of metal.
The present invention relates to pecan retrievers generally, and is concerned primarily with a device of this type which facilitates the picking up of pecans by minimizing the friction generated when an element of the retriever engages a pecan under pressure.
BACKGROUND OF THE INVENTION
Retrieving devices of the type with which the present invention is concerned are known. Such a device is disclosed in my copending application Ser. No. 860,926, filed Sept. 25, 1969 and entitled "Pecan Retriever" issued Aug. 17, 1971, as U.S. Pat. No. 3,600,029.
A device of this type includes, as characteristic and essential elements, a handle in the form of an elongate rod and an open bottom receptacle secured to the lower end of the handle. The receptacle includes side walls in parallel relation. A spring of generally U shape comprises straight legs joined by a straight back. The upper ends of the legs are anchored to the side walls of the receptacle on the outer faces thereof and adjacent to their upper edges. When so anchored the back spans the open bottom between the lower edges of the side walls.
In use the handle is grasped by a user and the receptacle positioned over a pecan lying on the ground. The open bottom is dimensioned so that the engagement of the back of the spring with a pecan causes the back to be deflected away from either the front or rear wall of the receptacle to permit and cause the pecan to enter the receptacle. This action is permitted by the spring properties of the legs.
It is evident that as the above described action takes place the back of the spring must ride over the pecan being retrieved. This generates friction to a high degree and impairs the riding action. It results in the necessity of high degree of pressure on the handle. This is undesirable.
OBJECT OF THE INVENTION
With the foregoing conditions in mind, the present invention has in view the following objects:
1. To provide, in a pecan retriever of the type noted, a spring including an open bottom spanning back and which spring has operatively associated therewith means for reducing friction created by engagement of the back with a pecan.
2. To provide, as a pecan retriever of the character aforesaid, a spring including a straight back together with means for facilitating riding of the back over a pecan.
3. To provide, in a device of the kind described, a U-shaped spring having a straight back with a roller rotatably mounted thereon.
Various other more detailed objects and advantages of the invention such as arise in connection with carrying out the above noted ideas in a practical embodiment will in part become apparent and in part be hereinafter stated as the description of the invention proceeds.
SUMMARY OF THE INVENTION
The foregoing objects are achieved by providing a pecan retriever comprising a handle, an open bottom receptacle secured to the lower end of the handle and including parallel side walls, a U shaped spring having legs and a straight back spanning the open bottom with the upper ends of the legs being anchored to the outer faces of the side walls, and a roller rotatably carried by the straight back.
For a full and more complete understanding of the invention reference may be had to the following description and accompanying drawing wherein:
FIG. 1 is a perspective of a pecan retriever incorporating the improvements of the present invention.
FIG. 2 is a front elevation; taken on an enlarged scale of the lower end of the retriever of FIG. 1.
FIG. 3 is a vertical section, with parts being shown in elevation, of the mechanism of FIG. 2, being taken about on the plane represented by the line 3--3 of FIG. 2; and
FIG. 4 is a horizontal section taken on the plane of line 4--4 of FIG. 2.
Referring now to the drawing wherein like reference characteristics denote corresponding parts, and first more particularly to FIG. 1 the pecan retriever of this invention is illustrated as including a handle 10 in the form of an elongate rod and a receptacle designated generally R. Handle 10 has an out turned hand grip 11 at its upper end while receptacle R is secured to its lower end.
Receptacle R comprises a rear wall 12, a front wall made up of inclined sections 13 and 14, and side walls 15 which are in substantially parallel relation. Side walls 15 terminate at their lower ends in straight bottom edges 16. They, together with the lower edges of rear wall 12 and front wall section 14, define an open bottom.
Formed integral with rear wall 12 is an inwardly extending lower semicylindrical socket half 17 and an upper socket half 18. Complemental socket members 19 and 20 are secured to the outer face of rear wall 12 and cooperate with members 17 and 18 in defining a socket that receives the lower end of handle 10. The latter is formed with a recess 21 (FIG. 3) which receives a detent 22 on the end of a spring 23, the lower end of which is anchored to the exposed farce of socket member 17 by a bracket 24 secured thereto.
While it is not material to the present invention it is notable that spring 23 carrying detent 22 of recess 21 provides a detachable connecting of receptacle R on handle 10. In the copending application above identified handle 10 is formed with another recess opposite to recess 21 which provides for mounting receptacle R on the handle in a reversed position relative thereto.
A spring of generally U shape comprises legs 25 and a back 26 that is substantially straight. Side walls 15 are formed with upper extensions 27and the upper ends of legs 25 are secured to the outer faces of extensions 27 by brackets 28 as by welding or soldering. A metallic roller 29 is rotatably mounted on back 26. This may be accomplished by positioning the roller 29 on back 26 before legs 25 are bent into the U formation of the spring.
Roller 29 spans the open bottom of receptacle R below edges 16. In a central position it is slightly spaced from these edges and as it is deflected from this central position as by engagement with a nut it approaches closer to edges 16.
While the manner of using and mode of operation of the subject pecan retriever are believed to be obvious from the illustrations of the drawing and description of parts set forth above, they may be briefly outlined as follows:
A user grasps hand grip 11 to manipulate the retriever to position receptacle R over a pecan. In this vertical position roller 29 is in a central position and the spaces on the opposite sides thereof as determined by the lower edges of rear wall 12 and front wall section 14 are not of sufficient area for a pecan to pass therethrough. Downward pressure is now applied to the handle and, as the pecan is engaged, roller 29 is deflected to permit and cause the pecan to enter the interior of receptacle R.
This operation is made possible by the resilient and elastic legs 25 of the spring. After a pecan passes the roller 29 the the latter returns to its central position and is ready to pick up another nut.
It is evident that roller R rides over the pecan with a minimum of frictioned resistance to such movement.
While a preferred specific embodiment of the invention is hereinbefore set forth, it is to be clearly understood that the invention is not to be limited to the exact construction, mechanism, and devices illustrated and described, because various modifications of these details may be provided in putting the invention into practice.
