ATTUEJAZJE- nonnnr'amvrounior P OVIDE CE, itHoDE ISLAND.
v TnIcK'roo nT knIrnQ 1 To all whom it mayconccrn Be it known that I, Bonner ARMOUR, a subject of the King of Great Britain, and native of British India, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Trick Pocket-' Knives, of which the following is a specification. I
My invention has reference to-an improvement in knives and more particularly to an improvement in trick pocket knives.
The object of n'iyiinvention is to construct a trick pocket knife in which the blade is locked in the handle, what appears to be the means of unlocking the blade being a deception, the true means for locking and unlocking the blade being concealed.
A. further object of my invention is to construct such a trick pocket knife so that the blade may be locked in either theclosed or open position.
My invention consists in the peculiar and novel construction of a trick pocket knife having details ofconstruction, as will be more fully set forth hereinafter and claimed.
Figure l is a side view of my improved trick pocket knife locked. i
Fig. 2 is a side viewof theknifeunlocked.
Fig. 3 is a side view showing the knife unlocked and the sides of the handle partly separated in the act of opening the knife.
Fig. 4 is a longitudinal sectional view through the knife in the open position, and
Fig. 5 is an enlarged transverse sectional view through the lock taken on line 5+5 of Fig. 1 in the locked position.
In the drawings 6 and 7 indicate the pivoted sides of the handle and 8 the pivoted blade. The side 6 has at the butt end an inner stud 9 with a head 10 which enters a recess 11 in the inner face of the side 7. Both sides have a skeleton 12, each skeleton 12 having a pivot extension 13 in which are cut in portions 14:, 141, the ends of which engage with pins 15, 15 on the pivot end of the blade, to open'and closethe blade. The side 6 of the handle has the usual bolster 16 fixed to the skeleton 12. The side 7 of the handle has a corresponding movable bolster 17 fixed to a bar 18 which slides in a groove 19 in the side 7 and has a forked end 20 which engaging with the stud 9 under'the head 10 looks the knife in either a the closed or open position. The blade 8 Siieci ficationtf Letters Batent. I .L Aug, .1 Application filed July 23,1919. *Seria1 Nofl312J44.
is. pivotally secured to the extensions 13 between the same, by a pivot pin 21 and to each end of the pivot pin, and laying against thefface of theextensions 13, 13 is pivotally secured a disk 22 having numerals 23, each of said disks having the appearance of the dial of a combination lock or safe lock.
The end of the fixed bolster 16 and the end of the movable bolster 17 also have 'nuk merals 24 adjacent to the numerals 23 on have now carried out and hold the blade in the open position, as shown in dotted lines in Fig. 3. The stud 9 is now snapped into the recess 11 and the movable bolster 17 pushed back, forcing the fork end 20 under the head 10 on the stud 9, thereby locking the knife in the open position. The knife is closed and locked by following the first part, reversing the second part and following the last part of the above operations. The disks 22, 22 with numerals having the appearance of safe lockdials and the numerals on the bolsters 16 and 17 are a blind for giving the impression that the 1. A trick pocket knife having a two part handle, extensions on the handle parts,
an intermediate blade, a pivot pin through the handl extensions and the blade, concealed means for locking the blade in the handle and deceptive means rotatably secured to the pivot pin, whereby the deceptive means hasthe appearance of the means for unlocking the knife.
A trick pocket knife having a two part handle, extensions on the handle parts,
an intermediate blade, a pivot pin through the handle extenslons and blade, means on the extensions engaging with means on the blade to open and close the blade, a headed stud on one handle part which enters a recess in the other. handle part, a moveble bolster having abar with a forked end which engages with the headed stud,t0'
lock the knife in the closed or open 0sition, numerals 0n the end of the ho ster a on the end of the pivet pin and having numerals on its-fae,fv vhereby the knife is locked or unlocked by mcying the moyable bolster, and the disk with the numerals and the numerals en the bolster are decep I tive,' estliey have *theappearance of the means .fqr locking 0r unlocking the knife.
