' ADJUSTABLE GRIPPING TOOL. 1
APPLIOATIdN FILED OUT. 27. 1905.
UNITED STATES PATENT OFFICE.
WALTER PUNT, OF JOHANNESBi'JRG, TRANSVAAL, ADJUSTABLE GRlPPlNG-TOOL.
Specification of Letters Patent.
Application filed October 2'7, 1905. Serial No. 284,761.
Y Patented March 20, 1906.
IO. ments of a like nature of which the jaws are" opened or closed by the action of a free-running adjusting-nut working on a thread cut on one of the members in a slot or recess in the other member. The nut is divided or duplicated, so that for adjusting purposes the two parts are turned together and are I locked by a slight relative movement.
In the accompanying drawing, which represents a spanner constructed according to this invention, the two nuts 0 and D are worked together in the ordinary way in opening or closing the jaws A and B of the spanner to the required size. The lower nut D is then screwed down and the u per nut O 2 5 screwed up as far as possible, which fixes the jaws A and B and prevents the continual slippin which is a universal experience in using t e ordinary shifting-spannerdle, a second jaw, a handle attached to the relative movement to lock the tool in its ad-' What I claim as my invention, and desire to secure by Letters Patent, is
1. In an adjustable gripping-tool, the combination of one member carrying a screwed spindle, another member having a recess t erein and two nuts in the recess engaging with the screwed spindle and capable of in- 3 5 dividual engagement with the top and bottom respectively of the recess.
2. In an adjustable gripping-tool, the combination of one jaw carrying a screwed spinsecond jaw and having a recess, two nuts en' gaging the spindle and disposed in the recess so that for adjusting purposes the two nuts are turned together while they are capable of justed position.
In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses.
