Application May 2, 1932. Serial No. 608,676
6 claims. Y (ol. sl-as) This invention relates to new anduseful improvements in a combination safety fuse puller and hand tool. n
The invention has for an object the construction of an article as mentioned which is characterized by the Afact thatA it is substantially entirely constructed from insulating material and adapted to pull a fuse from its socket without any danger of,shol t circuiting. l
Furthermore, the invention also proposes the arrangement of novel means for causing the jaws to be opened and closed.
Furthermore, the invention proposes the construction of an article of the classf described terial part of this disclosure:
, upper portion of Fig. 8.
Fig. 1 is a side elevational view of an article constructed according to this invention.
. Fig. 2 is a side elevational View of Fig. 1.
Fig. 3 is a fragmentary view similar to the upV Y per portion of Fig. 2 but showing vthe jaws in anv open position.
Fig. 4 isa horizontal sectional view taken on.
the line 4 4 Aof Fig. 3.-- y ,K
Fig. 5 is an enlarged fragmentary View of the Fig. 6 is a side elevational View of Fig. 5. A Fig. 7 is a sectional view'of an article constructed to a further modification of the invention. Y Y v Fig. 8 is a view similar to Fig. 2 but illustrating a modication. y The combination safety fuse puller and hand tool comprises a tubular body 1.0 formedv with av pair of longitudinally opposite top slots 11 in A?.
which a pair of jaws `12 rest and protrude. slide 13 is arranged within the tube 10. The jaws 12 and their inner ends pivotally connect upon the upper end of the slide 13, indicated by reference numeral 14. Across pin 15 engages through an elongated slot 16 formed in the sides Y of the tube 10 and engaging within an opening in the slide 13 forming a construction whereby the slide Vmay be moved by motion of the pin.
A means is provided for causing the jaws 12 )controls the opening of the jaws.
to assume open positions when the slide 13 is moved upwards and particularly comprises a pin 17 extended across the top and ofthe tube in between the jaws 12 and immediately above tapered cam, surfaces 18 adapted to cause separation oi 60 the jaws when the slide is moved upwards. The pin 17 is so located that in conjunction with the bottom ends of the slots 11 the jaws are caused to assume open positions as illustrated in Fig. 3 All of the parts preferably should be made from insulation material. This is particularly true of the jaws 12, theoross pin 17, the tube 10 and the slide 13. It can readily be seen that when thus constructed a fuse ymay bedrawn from its socket without `any danger whatsoever of short circuit@` mg. o Y
In Figs. -5 and 6 a modication of the invention has been disclosed in which provision has been made for varying within certain limits the open ing Vaction ofthe jaws 12. This variation is-ac-f 7 complished by the provision of means for changing the location of the transverse pin 17 which The pin 17 extends through slots 20 formedV in the sides of the tube lo and xed within lugs 21 immediately 8 to the-sides of the tube. -a ring 22 slidably mounted upon the tube and These lugs project from held in various fixed positions by the provision of set screws 23 which threadedly engage through the ring and abut against the side of the tube. A change in the location of the cross pin 17 will correspondingly affect the opening of the jaws 12 Vwhen the slide 13 is raised.
In Fig. 7 another variation of the invention ha" been disclosed in which provision has been made fornormally forcing the jaws to an open position and arranged in a manner so that closing is easily accomplished. In detail, this form of the invention comprises a tubular body 25 closed at Y the bottom end 26.V At the top ons this tubular;y
Vaction of the jaws against the inside of the tube.
A cross pin 33 engages through elongated slots 34 in the sides of the tube 25 and is flxedly con- `moored with the slide 2a. A spring 35 acts loef110 'fao tween the closed bottom 26 and a collar 36 secured upon the'slide 28 so as to normally urge the slide into the raised position. The jaws 29, the tube 25, the cross pin 30 and the cross pin 33 should be made from insulating material.
The tool may be used for various other purposes besides the drawing of fuses from their sockets. In all cases, the device is manipulated rto cause closing of the jaws for gripping the various articles.
While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as defined in the appended claims.
