HAND-TOOL- Specification of Letters Patent.
Patented Oct. 16, 1906.
Application filed April 22, 1905. Serial No. 256,964-
To all whom it may concern.-
Be it known that I, HENRY GEISENHoNER, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Hand- Tools, ofwhich the following is a specification.
The present invention relates to handtools, and more particularly to self-impacting pluggers and priclcpunches.
The object of my invention is to provide a durable and economically-constructed tool of this character which may be directly actuated to produce any desired force of impact without necessitating the adjustment of auxiliary parts.
The invention is shown applied to a prickpunch in the accompanying drawings, in which Figure 1 is a side elevation with the parts in their normal position, and Fig. 2 is an axial section with the impact member in its distended position.
The prick-punch consists of a pointed member 1, an impact member 2, and a tension member 3. The pointed member 1 is shaped at its lower end in the usual manner. At its middle portion 4 it is made cylindrical and is preferably knurled. At its upper end it has a reduced threaded portion 5 and a short cylindrical portion 6 of less diameter than the threaded portion and is provided with a flat surface 7 at its free end. Extending from the upper and through nearly one-half the length of the member 1 is a small axial bore 8. The impact member 2 has a cylindrical upper end 9, preferably knurled and of the same diameter as the middle portion 4 of the pointed member, a threaded portion 10 of reduced diameter below the cylindrical end 9, a plain cylindrical portion 11 beneath the threaded portion 10 and of less diameter, and a cylindrical guidespindle 12, extending axially from the lower end of the cylindrical portion 11 and of a diameter to freely enter and telescope with the axial bore 8 in the pointed member 1. square shoulder 13 is formed at the lower end of the cylindrical portion 11, which is adapted to impinge upon the flat-surfaced upper end of the pointed member 1.
The tension member 3 consists of a helical spring made of roundwire with its respective spirals normally in contact and connected at its respective ends to the pointed member 1 and the impact member 2 by screwing the threaded portions 5 and 10 into the ends of the helix. By making the diameter of the threaded portions slightly larger than the internal diameter of the helix a secure connection may be obtained, or when it is desired they may be brazed together.
In using the pricke punch the pointed member 1 is held in engagement with the work with one hand, while the impact member 2 is raised by the other hand against the tension of the spring 3 to a height according to the impression it is desired to make in the work and released, whereupon the spring causes the member 2 to descend with the requisite force, and being accurately guided by the telescopic action of spindle 12 in en gagement with the side walls of the bore 8 the shoulder 13 is caused to impinge upon the flat upper end of the pointed member 1 with the desired impact.
I do not desire to restrict myself to the particular form or arrangement of parts herein described and shown, since it is apparent that they may be changed and modified without departing from my invention.
What I claim as new, and desire to secure by Letters Patent of the United States, is
1. A self-impacting tool consisting of a pointed member, an impact member, telescopic means carried by said members for guiding the latter member relatively to the former, and a tension member connecting the other members. 1
2. A self-impacting tool consisting of a pointed member provided at one end with an axial bore, an impact member provided at one end with a guide-spindle adapted to enter said bore, and a helical spring connecting said members.
3. A self-impacting tool consisting of a pointed member provided at one end with an impact surface and an axial bore, an impact member provided at one end. with an impactshoulder and a guide-spindle adapted to enter said bore, and a helical spring surrounding and connected to the end portions of said members.
In witness whereof I have hereunto set my hand this 21st day of April, 1905.
HENRY GEISENHONER.
Witnesses:
HELEN ORFORD, G. O. HOLLISTER.
