H. KNIGKMANN. Tool for Removing Pintles from Hinge-Joints.

HENRY KNIOKMANN, or EAST NEW YORK, N. v.
IMPROVEMENT l N TOOLS FOR REMOVING PINTLES FROM H INGE-JOINTS.
Specification forming part of Letters Patent No.
203,466, dated May 7, 1878; application filed March 28, 1878.
To all whom it may concern:
Be it known that I, HENRY KNIOKMANN, of East New York, in the county of Kings, State of New York, have invented a new and useful Improvement in Tools for Removing Pintles from Hinge-Joints, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing, in which- Figure 1 represents a side view, partly in section, of a tool containing my invention. Fig. 2 is an inverted plan view of the jaws of the instrument; Fig. 3 is a front view of the jaws of the instrument.
Similar letters indicate corresponding parts.
This invention consists in the combination, in a tool for removing pintles from hingejoints, of a plate provided with one or more fingers or projections, which plate is attached V to the front of one of the jaws of the tool, and a plate attached to the other jaw, said latter plate having notches or perforations corresponding to the fingers of the other plate, so that by placing one of the fingers against a pintle, and compressing the jaws of the tool, the pintle is forced out of the hinge through the perforation in the opposite plate.
In the drawing, the letters A A designate the handles of the tool. The jaws are represented at B B. To the front of one of these jaws is screwed or otherwise attached a plate, a, of metal or any desired material. This plate is provided with one or more fingers or projections, b b b, Fig. 3. My object in having several fingers is that I can make them of different diameters, so as to it into hinges of different sizes. To the other jaw of the tool is fastened a plate, a. This plate has notches or perforations d d d, corresponding in number and position to the fingers b b b.
The object of this tool is to remove the pintles, chiefly, in jewelry, watches, and other objects of a similar nature, whose delicate construction has heretofore caused great difficulty in removing the pintles of their hinges; but of course I do not limit myself to the use of the instrument in this sort of work, but may use it in removing the pintles of any hingejoint.
The screw e in one of the handles A forms an adjustable stop, which prevents the jaws from being compressed too far.
The instrument can also be used to punch holes, for which purpose I provide the following device: One of the jaws of the instrument is provided with screws f f, whose ends have round, square, and other forms, according to the hole to be punched. These ends pass into perforations h h of corresponding form in the plate 0. The jaw to which the plate 0 is attached is forked, as seen in Fig. 2, so as to allow the pieces of metal which have been punched out to fall through the holes h h. The screw z is merely to strengthen the forked ends of the jaw.
The chief object of my tool is to provide a ready means for removing the pintles from hinges, and the mode of accomplishing this is seen in Fig. 1. The plate 0 is placed against the hinge so that the pintle rests over one of the notches or perforations d. A corresponding finger, b, is placed against the pintle, and on compressing the jaws B B the pintle is forced out through the notch or perforation cl.
WhatIclaim as new, and desire to secure by Letters Patent, is-
The combination, in a tool for removing pintles from hinge-joints, of a plate, a, provided with one or more fingers, which plate is attached to the front of one of the jaws of they tool, and a plate, 0, attached to the other jaw, said latter plate having perforations corresponding to the fingers of the other plate a, all combined and operating substantially in the manner set forth.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 21st day of March, 1878.
HENRY KNIOKMANN.
