BRONISLAW JAWOISCH, yOl CHCAGO, ILLINOIS.
Knr'rn on' Toon Application filed December 3l, 12515.
To all whom t may concern.'
Be it known that l, Baer-renew JAwoisoH, a subject of the Czar of Russia, and resident of Chicago, in the county of Cook and State of lllinois, have invented certain new and useful lmprovements in `Knives or rlools, of which the following is a specification.
My invention relates to improvements in knives or tools, and the like, and more particularly to knives or tools in which the blades are adapted to be folded in a handle so that they may be conveniently carried.
rlhe objects of the invention are to so construct a knife or tool of this character that the blade or blades thereof may be easily and quickly opened or closedby one understanding the manner of operating the same and can be locked in leither their open or closed position.
l accomplish the foregoing objects as here` inafter described in the following specification and as particularly pointed out in the appended claims, reference being had to the accompanying drawings in which an embodiment of my invention in the form of a po-cket knife is shown.
ln the drawings: Figure l represents a side view of a pocket knife constructed in accordance with my invention, the corkscrew attach ment thereof being illustrated in the open position in dotted lines and in closed pesition in full lines. 2 is a similar view with one blade open. Fig. 3 is a side elevation with the outer ornamental portion of one side of the handle removed to expose the construction and arrangement of the blade locking` slide bolt. Fig. t is a view similar to Fig. 3 with the handle side turned on its pivot preparatory to opening the blade.
e Fig. 5 is an enlarged detail nview of the transverse arm ofthe lockbar. Fig. G is an enlarged edge elevation of a fragment el' the end of the knife with the outer plate raised. Fig. 7 is a central longitudinal sec` J tion through my improved knife.
In referring to the accompanying drawings in detail, like numerals indicate corre spending parts in the embodiment of my invention shown.
The tool as illustrated comprises a hamlle and blades or the like pivotally mounted in said handle. rlhe handle is formed of a series of thin flat metal plates superimposed upon each other, the inner plates being cut away to provide recesses in which the blades seat when closed. The outer members comprise Specification of Letters Patent.
Patented fling., l5, i916..
Serial No. 69,518.
the plates l and elements 9, of the handle,
and are each pivoted at one end only to the inner plates 2, by a pivot 31, and are adapted to be turned or rotated on said pivot in opening or closing the blades. As sho-wn, each blade a, is loosely mounted on the pivot,
.but is controlled in its opening or closing movement by the outer plate which has a semi-circular slot 5, in which a lateral prolthe inner plate 2 has a lateral eye lug 7 and two lateral stops S, which respectively project through openings in the outer plate when said outer plate is in locked position relatively to the inner plate. An ornamental side member 9 is mounted upon the outer plate and is fastened thereto by pins. rlhe 'under s ide of the member 9 is hollowed out 'to provide a space between said member and the outer plate within which a lock bar l is shdably` 'arranged I preferably construct -the lock `bar in the narrow tapering form shown in Fig. 3 and rigidly secure its outer extremity to a rounded metal end cap 1l on the side member. lts inner extremity l2 is fitted through the eye of the lug 7 when in locking position as shown and the movement of the lockbar is limited by a widened portion 13 which is located between the lug 7 and stops 8. The lock bar also has a transverse arm 14k which extends outwardly from a medial portion of the bar and has a downwardly bent end l which depends through a short longitudinal slot 1G in the outer plate. To additionally fasten the outer plate in place I may provide a cork screw 17 which is pivoted to the handle near the middle thereof with a stop pin 18 which projects in the path of the bent end l5 and prevents the lock bar being retracted sufficiently to release the outer plate.
The operation of my improved tool is substantially as follows: lllhe cork screw is first opened to its operating position as shown in dotted lines in Fig. l thereby removing the stop pin from the path of the bent end l5 of the arm 141-. The lock bar is now retracted by sliding the end cap of the side member of the handle on the outer plate from the position shown in full lines in Figs. l and 3 to the position shown in dot-- ted lines in Fig. 1, and thereby lremoving the extremity of the lock bar from the eye in the lug 7. The free end of the outer plate opposite its pivoted end is raised suliiciently to remove the lug 7 and stops 8 from the apertures in the outer plate through which they normally fit as shown in Fig. 6, and said plate is given a complete revolution on its pivot. The first half revolution is practically an idle movement as the projecting pin 6 slides freely in the slot 5 until it reaches the end of the same, where it strikes against the terminating wall which constitutes a turning shoulder and opens the blade during the second half revolution. The blade now being open it is locked in its open position by moving the lock bar in the opposite direction and thereby relocking the outer plate in place.. The locking bar 10 is fastened at its outer end to the end cap 11 by bolts 3, which are upset or enlarged at their opposite ends to secure the parts together. These bolts 3 extend in transverse alinement with the pivot pin 3fL which is located between the bolts. To shift the locking bar into or out of locking position, the end cap 11 is grasped by the fingers of the operator and moved longitudinally in the proper direction. Vhen the cap is moved out to the position shown in dotted lines in Fig. l, the locking bar is in its unlocked position and the opposite end of the side member may be lifted as shown in Fig. 6 and swung n a circular path to open or close the knife blade. The blade can be closed when desired by proceeding reversely to the opening operation.
I-Iaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent isl 1. In a tool of the class described, a handle having an inner member and an outer member pivoted at one end to said inner member, said outer member being adapted to be raised from the inner member at its opposite free end and revolved on its pivot, and one of said members having a short longitudinal slot, a lock bar slidably mounted within the outer member, an end ca movably mounted on the end of the handle Copies of this patent may be obtained for and connected to the lock bar, an angular stop extending laterally from the lock bar and having its extremity bent to project into the short longitudinal slot, means mounted on the handle and adapted to engage the bent extremity of the stop for securing said lock bar against longitudinal movement, when in its locking position, a blade in said handle adapted to be opened or closed by the revoluble movement of said outer member.
2. In a tool of the class described, a handle having a member pivotally mounted thereon so as to be capable of a revoluble movement and also provided with a long longitudinal recess and a short longitudinal slot on one side of said recess, a blade in said handle adapted to be opened or closed by the revoluble movement of said pivotal member, a lock bar slidablj7 mounted in the longitudinal recess, an end cap on the end of the handle and connected to the lock bar, said end cap and lock -bar being longitudinally shiftable together, an angular stop extending laterally from the side of the lock bar and having a bent extremity projecting into the short longitudinal slot, and a movable member attached to the side of the handle and adapted to engage the bent extre1nity of said stop to secure said locking bar against longitudinal movement when in its locking position.
3. In a tool of the class described, a handle having a revoluble member and also provided with an interior longitudinal recess and a short longitudinal slot, a blade in said handle adapted to be opened or closed by the revoluble movement of said member, a lock bar slidably mounted in the recess, a stop extending laterally from the lock bar and having a bent extremity projecting into the longitudinal slot` and a movable member attached to the side of the handle and adapted to engage the bent extremity of the stop to secure the lock bar against longitudnal movement when in its locking position.
