Abstract

An electromagnetic pick-up retriever tool (10) having a number of interchangeable accessories to assist in locating, illuminating, viewing and retrieving both magnetic and non-magnetic objects such as small mechanical parts. The tool (10) has a pistol-like handle (12) which contains the power source (30) and circuitry (42) and which has a receptacle (36) which selectively receives various attachments such as a bendable/reformable wand (106) having an electromagnet (120) at the end. Illuminating lights (216, 308) and fiber optic viewers (16) may be selectively attached to the device.

Claims

AMENDED CLAIMS [received by the International Bureau on 26 July 1994 (26.07.94); original claims 1-18 replaced by amended claims 1-18 (3 pages)]

1. A mechanics retriever for locating and retrieving objects, said tool comprising:

(a) a handle defining an internal compartment including a receptacle and

a power circuit operatrvefy connected to said receptacle;

(b) a plurality of interchangeable accessory tools including at least an

accessory tool having an elongate flexible and deformable and reformable wand member with a jack at its inner end detachably securable in said receptacle and having electrically operated retriever means at its opposite outer end, said accessory tool member extending axialfy from said receptacle in a non-deformed position; and

(c) said handle including a grip adapted to be manually grasped by the

user, said grip being disposed at an angle with respect to the non- deformable section of the wand whereby said retriever means may be selectively engaged in said receptacle at said jack and energized to assist the mechanic in manually location and retrieving objects.

2. The retriever of Claim 1 wherein said retriever means comprises light means.

3. The retriever of Claim 1 wherein said retriever means comprises an electromagnet.

4. The retriever of Claim 1 wherein said grip has a curved rear and front surface defining a pistol grip-like configuration.

5. The retriever of Claim 4 wherein said front surface has a plurality of finger-receiving recesses.

6. The retriever of Claim 4 wherein said power circuit includes includes a battery and said power circuit being selectively connectable to an auxiliary power source and further including indicator means for indicating low battery voltage.

7. The retriever of Claim 2 wherein said light means includes a lamp at the outer end of said wand.

8. The retriever of Claim 2 wherein said light means includes a lamp located adjacent the inner end of said wand and a light transmitting tube extending along said wand transmitting light to the outer end thereof.

9. The retriever of Claim 7 further including viewer means disposed on said handle and a transmitting means extending along said wand to transmit images from the outer end of said wand to said viewer means.

10. The retriever of Claim 9 wherein said viewer means includes focus- adjusting means.

11. The retriever of Claim 2 further including reflector means detachably securable at the outer end of said wand.

12. The retriever of Claim 1 wherein said wand includes an electrical conductor which is bendable and further including an outer insulative sheath-

13. The retriever of Claim 1 further including at least one extension means interposable between said accessoty tool and said handle and including means for electrically connecting said tool to said receptacle.

14. The retriever of Claim 6 wherein said indicator means comprises first and second light-emitting diodes having alternate conducting states whereby a predetermined vohage drop will cause said first light emitting diode to become deenergized and said second light emitting diode to become energized, said light emitting diodes emitting distinguishable light signals.

15. The retriever of Claim 1 wherein said retriever means comprises an electromagnet, claw means having jaw means and a magnetic attractable cam engaging said claw means and upon energization of said electromagnet to close said jaw means.

16. The retriever of Claim 15 wherein said jaw means are normally biased to an open position.

17. A mechanics retriever for locating and retrieving both metallic and non- metallic objects from difficult-to-reach locations, said tool comprising:

(a) a handle having an upper body portion and an angularly extending

grip, said grip being configured in a pistol-like configuration, said handle defining an interior compartment;

(b) a receptacle in said body portion;

(c) a power circuit disposed in said handle and having an actuating switch

and connectable to a power source to provide power to said receptacle;

and

(d) a plurality of interchangeable accessory tools incuding at least an

accessory tool having an elongate, flexible, deformable and reformable wand with connector means at the inner end detachably securable at said receptacle and having an electrically operated retriever means at the outer end, said retriever means being in selective electrical connection with said circuit across said switch when said connector means is secured in said receptacle.

18. The retriever tool of Claim 17 wherein said interior compartment defines a battery storage area and said' grip defines an access door to said interior compartment.
