POCKET-KNIFE.
Specification of Letters Patent. Patented Jan, 19 1915 Application filed June 18, 1912. Serial No. 704,365.-
To all whom it may concern:
Be it known that I, CARL H. WHITE, citizen of the United States, residing at Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Pocket-Knives; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
' My invention relates to improvements in pocket knives of the construction in which the blades are removable. In my present improvement, the tang of the blade is in two parts adapted to be connected by a removable fastening device so that when the parts are assembled and the fastening device is in place, the tang is practically'integral. When, however, it is desired to remove the blade for the purpose of substituting a new blade or a new or different folding tool of any kind, it is only necessary to remove the fastening device which, in the specific construction illustrated in the drawing, consists of a screw pin. In this construction, it is not necessary to make provision for releasing the tension on the blade when in the half open position, since the screw pin or other fastening device may be removed with the same facility though the spring ongages the tang with the usual tension. In fact, it is preferable in this form of construction that the tang should be acted on by the spring under tension as it holds the blade securely against movement during the removal of the fastening device.
Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.
In this drawing: Figure 1 is an end elevation of a knife equipped with my improvement. This is a view looking in the direction of arrow 1, Fig. 2. Fig. 2 is a fragmentary sectional view of a knife pro.- vided with my improvement, the pivot pin upon which the blade turns being shown in cross section and the two parts of the tangpartly broken away and sectionized to disclose the screw pin for fastening the two tang parts together. Fig. 3 is a similar view "with the tang fastened or securing pin removed, the blade being shown in the half open position and somewhat removed from same parts in all the views.
Let the numeral 5 designate each of the two side parts of a knife handle and 6 the main spring thereof. I In this form of construction, the tang 7 of the blade may be said to be composed of twoparts 8 and 9, the part8 being integral with the body of the blade and the part 9 separated therefrom and in reality forming a separate member curved as shown at 10 to fit the pivot pin 12 and acted on by the main spring. The tang member 8 in addition to a semicircular recess 13 adapted to fit the pivot pin 12 on the opposite side from the recess 10 of the part 9, is provided with an elongated opening 11 adapted to receive the tang part 9 when the parts are assembled, (see Figs. 2 and 4:). The tang part 9 is provided with an opening 15 which, when the blade is in the assembled position, registers with opening 16 and 17 formed in the tang part 8 on opposite sides of the slot 14. When the parts are assembled, the two tang members 8 and 9 are connected by a suitable fastening device. In the specific form of construction disclosed in the drawing, this fastening device consists of a screw pin 18 adapted to enter the openings 15, 16 and 17 of the two tang parts, one extremity of this screw pin is provided with the usual nick to receive the operating end of a screw from the spirit of the inventipn which broadly involves a blade composed of two separable tang parts arranged to coijp-erate when connected by a suitable fastening device, whereby it becomes practicable to remove the body of the blade and a portion of the tang from the handle upon the removal of the tang fastening. Of course, the object of a construction pf this character is obvious since it makes it practicable to remove a blade or folding tool carried by the knife handle and substitute another similar or different blade ;or tool, the one requirement-being thatthe tang portion of the blade or tool be identical in each case where by it is adapted to fit the knife handle and cooperate with the tang member which remains in place after the blade with its integral tang part has been removed.
'in order to remove the blade, it is only necessary to swing it on the pivot pin 12 to the half open position or to the position intermediate the wide open and closed positions, after which a small screw driver may be inserted in the nick of the screw pin, see Fig. 1), after which the screw pin may be turned to disconnect its threaded portion 19 from the tang part Assoon as the screw pin has been removed, the blade, together with its integraltang part, is, of course, free and maybe disconnected from the bandle and replaced or another similar blade or folding tool having an identical tang part 8 substituted therefor, As soon as the body of the bladeihas been put in place, thescrew pin is again applied,"when the structure is complete and secure as to all of its parts.
*Havingth-us described my invention-what '1 claim is: i 1, A knife blade including a plurality of coijiperating parts lying between the same parallel planes and respectively recessed to receive the pivot pin, the said parts having respectively a slot and a part entering the slot for interlocking purposes, the interlocking :parts having registering perforations formed edgewise therein to re- "ceive a fastening device;
'2. A knife blade having a tang formed in two separable parts lying between the same parallel planes and recessed to receive the pivot pin of the blade, one part of the tang having a slot which the other part enters, and the two parts having registering perforations adapted to receive ,a fastening means.
3. In a pocket knife, a tang formed in two separable parts, a blade integral with one ofsa id parts,-th.e two parts being transversely recessed to receive the pivot pin of the blade, one of said parts "having a -slot which the other part enters, and the two :parts having registering perforations to refceive a fastening means.
