Specification of Letters Patent.
Patented Jan. 22, 1907;"
Application filed October 11, 1906. Serial No. 333.388.
A To otzlZ whom/it may concern/.-
Be it known that I, ERNST HOLTGRAVE, a subject of the German Emperor, and a resi dent of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Scissors, of which the following is a specification.
The object of the present invention is to provide means for permitting the slackening and ti htening of scissors without the necessity of slackening the screw-bolt that connects the two blades thereof.
My invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of my improved scissors. Fig. 2 is a top View thereof. Fig. 3 is a vertical section on line 3 3 of Fig. 1.
My invention consists in a spring-plate a, which is arranged on the outer surface of one of the blades 7) to rest between the latter and the head of the joint or screw-bolt c. This plate is pointed and has a nose portion (1, directed toward the blade. Re istering with this nose portion and in a circle around the joint or screw-bolt are arranged a plurality of impressions e in the respective blade, into either of which the nose (Z is adapted to engage. The depth of all impressionspf the series being the same and the surface of the blade being slanting, it will be seen that upon disengaging the nose d from one of the iinpressions by slightly raising it and turning the plate a in one or the otherdirecti'on the nose in engaging another impression will impart more or less pressure on the blades, and thereby tighten or slacken the scissors,
What I claim, and desire to secure by Letters Patent, is
The combination with scissors, of a spring plate arranged on one of the blades and rotatively borne on the joint of the latter, said the respective blade, a plurality of equally deep impressions arranged in an arch around the oint on the slanting surface of the blade and adapted to engage the nose of the springplate, substantially as and for the purpose set forth.
