Application filed May "5, 1905- erial 1 To all .whont it may concern: I Be it known that we, )ISAAO Asn and AR- *rnnn SAYIL'ES, citizens of the United States,
' residing at Marquette, in the county of Mar- -is--a side elevation of -a "the case broken away to show the bolt and the''-locking-tumbler, the barrel of the im- =-vprovedkey being shown in section and the *ward or bit inelevation. Fig. 2 is -a sectionalj vieW-onthe line 2 2 of Fig. l with the key in Fig. 3 is a viewv :quette and State of Michigan, have invented anew anduseful Key, of which the following is a specification.
"This invention relates to keys, and is primarily designed to rovide a novel form of 'key ha-vingaffoldab e ward or bit capable of being housed within the barrel or shank of Y the key to permit introduction of the latter "into the lock and which is capable of being projected after being entered into the look,
so as to cooperate with the tumblers or other locking elements for releasing the bolt by manipulating the key in the usual manner.
Another objectof the invention is to maintain the ward or bit of the key projected in its operable position when use in the lock Without requiring any care on the partof the operator-and to enable the automatic return of the bitor ward into the barrel of the key "when the locking and unlocking operations- ;have'been completed, sodas to permit con-. venien-t withdrawal of the-keywithout re-k quiring any manual manipulation thereof to return the ward or !bit into the key.
With these and other objects in view, the present invention consists in the combination and arrangement of parts,-as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it
being understood that changes in the form, proportion, size, and minor details may he made within thescope of .theclaims Without "departing trom .the spirit or sacrificing any of the advantages of the invention,
drawqngs, Figure 1 1n the accompanyin lock having a part of its initial inserted position. "of the key, having one side of the barrel re- :nioved to disclose the means for projecting and withdrawing the ward or hit. Fig. 4 is a rear elevation of the ;bolt and its locking tumblers. 'Fig. 5is'a fragmentaryelevation v of the keyhole portion of one of the faceplates of the lock-case looking atthe-inner side thereof.
Like characters of reference designate corresponding parts in each and every --fig1j1re of the drawings.
In order that the operation of the present invention may be fully understood there has been shown in the drawings a form of lock with whichthe present key-is paIticuiar-lyde v signed to cooperate; but it lee-understood that the key forms-the subject-matter to %be I V -6s .clai-medin the present-application.
The lock includes an ordinary-case 1,:preferably of the mortise-type and provided in one edge with a bo-lt-opening 2. "The'oppo siteface-pla-tesof the'c'ase Of-i'fli'ilOOilCfiiBPDO" yided with corresponding internal enlargements '3 extending rear-wardly'-atopposite sides of the bolt-opening 2. Each faceplate is provided with a circular key-op en i-ng 4;, ex-
tending through the' enlargements 3- andhav I ing-. a slot 5 intersecting the lower -s'idegofthe opening a-nd the-enlargement, but not extend into the face-plate. Working in an end Wise direction through the opening '2 isjthe bolt 6," whi'ch-is received withina guideway 7., formed between the enlargements or guide members 3. Opposite-sides of the boltatthe rear and adj acent its upper edge areprogvided with longitudinal grooves 'orguideways 8, in-Whicharereceived guide ri bsvzor projections 9, carried by the guide ,nienrhers '3, whereby wthe bolt is held positionaand prevented'' from 3 dropping or tilting; (d'OWIl wardly. lSeneath each groove 8 the bolt is provided with a longitudinal recess or out away portion- 10,-which intersects the lower ing its lower edge adj-acent its rear end.
I-nleach recess 1 0 of the bolt there is a pair their forward ends :pivotally mounted up one common pivot pin. or projection 15 extend ing laterally from-the back wall-of-the recess 1-0. The rear free ends :of these tumblers ex tend inrear of the boltand are provided, :as
best shown inFig. 4 of-thedrawings, with the respective pendentfingers 1 6-and"1'7, do signed to take back of an upstandings'hoirl I r 1o 5 v der 18, carried by .-a- 'crossebar 1-9, extending between-the face -plates of the lock-case. The outer-tumbler 1-4 has in greater u ward movement than the innermember 1*3 which der 20 providediup on 'the backjoftherecesslfi 'isiirnited-initsupward mo-vernenflby-a'shoul- 1 r0 ZEaeh tumbler is normally and yieldably -mai-ntained at-its loweri limit by mean's'otn U-shaped spring 21, which is interposed between the top of the tumbler and the under side of the top edge of the recess 10, the free end of the lower side of the spring being bent transversely downward to form a shank 22, the extremity of the shank being bent or rolled to form a loop or enlargement 23, which is snugly received within an opening 24 in the upper portion of the tumbler, there being a notch or slot intersecting the top edge of the tumbler and the opening to receive the stem 22 of the spring, whereby the latter is secured to the tumbler without requiring any extraneous fastenings.
Surrounding the keyhole 4 in each faceplate and upon the inner side of each guide member or enlargement 3 is an annular flange 25, which is intersected at its lower side by a notch or opening registering with the slot 5 in the guide 3. Theupper portion of this flange underlies one or both of the tumblers 13 and 14, as shown in Fig. 2 of the drawings,
.so as to form a guard to prevent lifting of the tumblers except by means of the key expressly provided for the lock.
The key of the present invention includes .a shank or barrel made up of longitudinal sections 26 and 27, of which the section 26 is .site end to the plunger.
providedat one end with a transversely-disposed handle 28.
In the inner fiat face of the key-section 26 there is an irregularlyshaped longitudinal passage or channel 29, which intersects the rear handle end of the section and terminates short of the front end .thereof, where it intersects one longitudinal edge of the shank or barrel, as shown at 30. In the forward portion of the channel or passage 29 there is a bit or ward member 31, which is pivotally supported at its rear outer corner, as at 32, and is provided in its opposite edges with corresponding notches 33. At
.the middle of the front free end of the ward there is a projection 34, and spaced at suit-1 able intervals at opposite sides of this projection are other shorter projections 35 and 36. .In rear of the ward or bit there is a plunger 37, which is rojected in rear of the handle 28 and has its orward end connected to the bit or ward by means of a link 38, which is pivoted at one end to the ward and at its oppo- The plunger is provided with a lateral shoulder 39 working between shoulders 40 and 41 in the channel or passage 29, and there is a helical spring 42 interposed between the front side of the shoul- .der 39 and the rear side of the shoulder 40, .wherebythe plunger is normally and yieldably held at its rearward limit, so as to retract or draw the bit or ward 31 entirely into the shank or barrel of the key. A shoulder 43 upon the plunger is arranged to engage the front side of the shoulder 40 to limit rearward movement of the plunger.
To project the bolt 6 from its retracted position, (shown in Fig. 1 of the drawings,) the barrel of the key is introduced into either of the keyholes 4, and then the plunger of the key is forced forwardly, so as to swing the bit or ward 31 into a position at substantially right angles to the barrel, as shown in Fig. 2 of the drawings. It will here be explained that this projecting of the ward can be accomplished only when the opening 30 in the side is in alinement with the slots 5 of the guards 3. WVhen the key is turned, the guard members 25 are received within the notches 33, the projections 35 and 36 engage and lift the respective tumblers 14, while the tumblers 13 are lifted by the back walls of the recesses between the middle projection 34 and the side projections 35 and 36 until the fin gers 16 and 17 of the tumblers are elevated above the top of the shoulder 18, whereupon the central )rojection 34 strikes against the front wall 0 i the notch 12 in the under side of the bolt 6 and moves the latter forwardly until the ward turns downwardly out of engagement with the bolt and the tumblers and. the fmgers of the latter drop in front of the shoulder 18, which looks the bolt against being moved inwardly.
Having fully described the invention, what is claimed is 1. A key comprising a shank provided at one end with a handle and also having a longitudinal passage piercing the handle and provided at its opposite end with a lateral ranch intersecting one side of the ke a ward located within the branch passage and capable of being projected outwardly therethrough, a plunger working in the passage with one end in cooperative relation with the ward and its other end extending outwardly through the handle, and a spring to yicldably hold the plunger at its rear limit.
2. A key comprising a shank having a handle at one end and provided with a longitudinal passage intersecting the handle, and its other end provided with a lateral branch passage intersecting one side of the shank, shoulders within the passage, a ward normally contained within the branch passage and capable of b eing projected therethrough, a plunger working in the longitudinal passage and provided with a shoulder working between the shoulders of the passage, a link connecting the plunger and the ward, and. a helical spring interposed between the shoulder of the plunger and the forward shoulder of the passage to hold the plunger retracted with its rear end in rear of the passage.
In testimony that We claim the foregoing as our own we have hereto aiiixed our signatures in the presence of two witnesses.
