CUTTING NIPPERS Filed Jur 9, 1946 JOHN AR V/D SKOO IN VEN TOR.
KJKW
AT Ty.
Patented May 1, 1951 Application July 9, 1946, Serial No. 682,193 In Sweden February 22, 1945 2 Claims.
mounted and provided with an arm actuated upon by handles at the rear end of the tube by means of an intermediate rod within the tube.
One object of my invention is to provide a tool which needs extremely small space laterally.
Another object of my invention is to provide an arrangement of parts whereby an easy change of jaws will be possible.
Other objects will appear hereinafter.
The invention consists in the novel combination and arrangements of parts to be hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawing, showing the preferred form of construction and in which:
Fig. 1 is a side view of the nippers with the jaws opened; and
Fig. 2 is a similar side View of the upper portion thereof with shut jaws;
Fig. 3 shows a plan view of a detail; and
Fig. 4 a side view thereof.
The nippers are constructed to have a great length by means of an intermediate tube 4 between the handles I and the jaws 2, 3. The handles are swingably mounted to the rear end of the tube, and at the forward end thereof the one jaw 2 is secured for instance by means of an easily detachable pin 5 or such like. The other jaw 3 is turnably mounted to the jaw 2 coacting therewith, and is provided with a laterally directed arm 6 with a cross pin I.
The pin 1 is arranged to fit into an open bearing 8 at the one end of a link 9, the other end of which is at IU swingably mounted to a slide shoe II on the tube. This slide shoe is connected to the forward end of a rod l3 by means of a screw 12 or such like entering an oblong aperture in the tube, said rod being slidably guided within the tube. At the rear end the rod is linked to the handles I in such a way that the rod will be pushed rearwards when the handles are pressed towards each other, and forwards when the handles are separated. The bearing 8 is open towards the arm 6 so that the pin 1 can enter the v bearing when the link 9 is swung towards said arm. To maintain the pin in the bearing the link is provided with a slide M with a fork end !5 which will cover the rear surface of the pin when pushed forward into position, in such manner preventing the pin 1 from slipping out of the bearing. The slide I4 is retained in its forward position by a stopper in the shape of a spring pin l6 inserted into a boring in the link 9 and abutting against the rear end of the slide. When the slide [4 is to be drawn back the sprin pin I6 is fully pressed down into its boring enabling the slide to pass over the upper end of the spring pin in a backward movement, and the link 9 can be swung outwards releasing the pin 1.
In use the jaws will shut when the handles are pressed towards each other forcing the rod l 3 to a rearward. movement within the tube 4, the jaws gripping the object, a pin or such like which has to be nipped or cut off. The movement is transmitted by means of the link 9 which turns the jaw 3 towards the jaw 2. The cutting force is very strong as the movement of the handles is reduced by the transmitting parts to a small movement of the jaw. The force is transmitted in such a way that the essential parts are exposed to pulling stresses only, thus the parts can be given slender dimensions. As the only laterally extending part, the link 9, is directed closely along the tube the need of space laterally is inconsiderable. On account of the construction of the disconnectable pin 1 and the demountable jaws these can easily be changed for jaws of other types and the tool can be used for different purposes.
It will be understood that modifications may be made within the spirit and scope of the appended claims.
Having thus described my invention what I claim is:
1. Cutting nippers for objects difiicult of access, comprising a tube, two jaw members, one jaw member fixed to the forward end of the tube and the other jaw member pivotally mounted to the fixed jaw member, both jaw members extending substantially forward in the direction of the tube, a rod slidably positioned within the tube, rearwardly extendin handles pivotally mounted to the rear end of the tube, linking members each connected to one of said handles and to the rear end of the rod whereby the rod is pushed backwards and forwards when the handles are closed and opened, respectively, said pivotal jaw member provided with a laterally extending arm, a link connected to the arm and extending rearwardly closely along the outer side of the tube, the forward end of the rod connected to said link by means extending through an aperture in the tube wall whereby actuation of the rod by the handles will cause movement of the pivotal jaw member toward and away from said fixed jaw member. 7,
2. Cutting nippers for objects difiicult of access, comprising a tube, two jaw members, one jaw member fixed to the forward end of the tube and the other jaw member pivotally mounted to the fixed jaw member, both jaw members extending substantially forward in, the direction of the tube, a rod slidably positioned within the tube, rearwardly extending handles pivotally mounted to the rear end of the tube, linking members each connected to one of said handles and to the rear end of the rod whereby the rod is pushed backwards and forwards when the handles are closed and opened, respectively, said pivotal jaw member provided with a laterally extending arm having a free end provided with a cross pin, a link having at one end a bearing groove to receive said cross pin, a movable slide member on said link to, detachably' engagev the pin in the bearing groove when the slide is moved in a forward position and means to lock said slide in the 4 forward position, said link extending rearwardly closely along the outer side of the tube and the other end of the link connected to the forward end of the rod by means extending through an aperture in the tube wall whereby actuation of the rod by the handles will cause movement of the pivotal jaw member toward and away from said fixed jaw member.
