PIN EXTRACTOR AND DRIVER.

Specification of Letters Patent.

Patented Feb. 16, 1915.

riginal application filed November 12, 1910, Serial No. 592,082. Divided and this application filed January 18, 1912. Serial No. 671,995.

T0 all whom it may concern:

Be it known that I, Louis A. BENEGKE, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Fin Extractors and Drivers, of which the following is a specification.

This application is a division of one filed by me November 12, 1910, Serial No. 592,082. p

This invention consists of a device for the easy and convenient insertion of pins into papers and the like and removal of same therefrom without pain or injury to the thumb, fingers, or hand. In oflices where many papers are handled, it has been found by experience that the fingers and other members of the persons Whose occun pation requires them to insert pins in and remove same from papers, documents, and the like become injured. In the course 0f a day one person will push so many pins into and through papers and remove so many pins from the like that the skin of one or more of his digits will become abraded to a great extent not only causing him to suffer pain from further use thereof in pushing and pulling pins, but, also, to cause him to be exposed to great danger of blood-poisoning or other unhealthful contamination. While these conditions arise when fresh shiny pins are pushed into or removed from papers yet it is well known that pins rust when left for a while in papers, which produces the result of increasing the diliculty of withdrawing them.

The present invention provides means whereby the pressure of the pinhead upon the cuticle is obviated or relieved during the operation of insertion or withdrawal of a pin and, generally stated, consists of a stock, which usually and preferably though not in all cases necessarily will be in the form of a lead pencil, pen, or light common implement having therein a socket, or the like. The cap for the point of an indelible lead pencil, pen, or any other instrument may be socketed, in order to construct this device. Likewise the device may be manufactured as an implement in itself apart from combination with common writing instruments and the like.

In the accompanying drawings forming part of this spiation, like numbers of reference denote like parts throughout the several views.

Figure 1 is an elevation showing a lead pencil equipped with the present invention; Fig. 2 is an enlarged sectional view taken on the line 2 2 of Fig. 1, showing the device in the act of driving a pin; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1, and Fig. 4 is a view similar to Fig. 2 showing the device in the act of extracting a pin.

The drawings illustrate a pencil 1, equipped with the usual metal sleeve 2 that carries the rubber tip 3. rlhe sleeve 2 is provided with a socket 4 or a plurality of same, preferably two located diametrically opposite to one another, the sockets being formed by striking or bending out the metal of which the sleeve 2 is made. The sockets in longitudinal section, as depicted in Figs. 2 and 4 are formed to have two walls 5 and 6 that are arranged to form an acute angle, the walls 5 of each socket being shorter than the wall 6 thereof.

By reference to Fig. 2 of the drawings it will be seen that the walls 5 and 6 of the sockets form surfaces which engage points on the under side and the top face respectively of the pin head 7 when the latter is being driven into position, the angular relation of the walls 5 and 6 being such that they conformably engage the pin head as aforementioned. ln driving the pin the wall 6 acts to impart the necessary pressure to the pin to move same in position, while the wall 5 acts as an abutment or guide to hold the pin head in engagement with the wall 6. The wall 5 at its outer end forms a comparatively sharp nose 8 which, when caused to engage on the under side of the pin head, effects extraction of the pin in a manner depicted in Fig. 4 of the drawings.

As above stated Fig. 2 depicts the device in the act of driving the pin, and to extract the pin the stock 1 in Fig. 2 is given a slight anti-clockwise movement, to cause the nose 8 to engage the under side of the pin, and at the same time is moved outwardly in a direction to effect the extraction. The width of the socket is such that the end walls 9 thereof prevent undue lateral play of the pin head to thereby enable the device to more effectively perform its functions. Since in the act of driving both. Walls 5 and 6 engage the pin head, it will be seen that the pin will be held in steady position, enabling effective insertion thereof.

For dress makers, who do not have pencils and pens convenient, but who nevertheless constantly use a great many pins, this invention can be placed at some convenient point on a bodkin or other implement or may be made as a separate tool.

What is claimed is:

The combination with a lead pencil of a pin-extractor comprising a metal sleeve formed with a substantially oval-shaped depressed recess which extends transversely of the longitudinal axis of the said sleeve, which said recess consists of a socket having the inner walls thereof approximately forming an acute angle and having its bottom, both sides, and its inner end closed, the said recess having a sharp outer edge formed so as to engage the head of a pin when the latter is disposed transversely of the longitudinal axis of the sleeve, the bottom of the recess being `for engagement with the outer face of the pin-head and the inner end wall being disposed so as conformably to engage the beveledlower side portion of the pin-head, whereby in driving` the pin the bottom of the recess bears against the outer face of the pin-head and in extracting the pin the inner end wall of the recess bears against the said beveled lower side portion of the pin-head, said side walls of the recess being for engagement with diametrically opposite points on the pin-head periphery to hold the latter against movement longitudinally of the sleeve.

ln testimony whereof I hereunto alix my signature in the presence of two witnesses.

LUUIS A. BENECKE.
