KEY.
Application filed. February 21, 1923. Serial No. 620,380.
To. all whom it may concern:
Be it known that I, ANroNro PAeLIUco, a subject of King of Italy, and resident of Natick, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Keys, of which the following is a specification.
This invention relates to keys and more particularly to that type of key having a retractable bit and adapted to be inserted into the look through a circular key hole.
Principal objects of the invention are to provide a key of this type of compact and durable construction, whose moving partsv are few,.simple, and readily manipulated by the fingers of one hand, and provided with guardgmeansfor preventing access of dirt or lintto the moving parts when the key is not in use. In the accompanying drawings in which the invention is illustrated:
Fig. 1 is-a side elevation of the key to enlarged scale with the bit in operative position and the guard retracted;
Fig. 3 is a top plan view of the key with the parts positioned as in Fig. 2;
Fig. 4 is a fragmentary perspective view to smaller scale showing the inner side of a door with a lock of usual type applied thereto;
Fig. 5' is a fragmentary perspective view showing the opposite side of the door provided with a key hole of a kind permissible with a key of the type to which the present invention relates;
Fig. 6 is a fragmentary section through a lock showing the new key inserted therein with its bit positioned to actuate the wards of the lock; and
Fig. '7 is a section on the line 77 of Fig. 3 but to a larger scale."
The improved key comprises a handle 1 of any usual form and a'shank 2 having a narrow axially extending chamber 3 in which a slide 4 is arranged. Preferably the shank is tubular and made of metal and a longitudinally slotted filler piece 2 is secured within its bore, the slot in the filler and the wall of the tubular shank desuch as 18 or head 7 which is spaced slightly from the upper surface of the shank and by means of which the slide may be moved longitudinally in the chamber 3. Near the end of the shank the walls of the chamber 3 are slotted at 8, 9 respectively, and within this part of the chamber the bit 10 is pivotally supported upon the pin 11. The longer end of the bit is provided with the usual notches or projections to cooperate with the'wards of the lock while the shorter end of the bit is slotted for the reception of the forward end of a link 12 which is pivotally connected to the bit by means of a pin 13. The link extends rearwardly along the chamber 3 and is pivotally connected to the slide 4 by means of a pin 14.
A guard 15 in the form of a split sleeve embraces the shank 2 and may slide longitudinally of or turn upon the latter. This guard has a slot'l6 of a width sufficient to permit passage of the stem 6 of the finger piece and one end of the slot is preferably flared at 17 to facilitate entrance of the stem. I
A look 18 of usual type is shown in Fig. 4 as applied to the inner side of a door. This lock is preferably furnished with a key hole 18 of ordinary shape at its inner face and with Wards 19, 20. Preferably, however, the wards should be thinner than usual in order to avoid the necessity of making the key bit wider than can conveniently be concealed within a shank of permissible diameter. The front or outer side of the door is furnished with a circular key hole 21 of a diameter to admit the shank of the key and may be surrounded by an 'escutcheon plate 22 if desired.
key is to be used the guard 15 isturned.
until the slot 16 is aligned with the stem 6' and then drawn back to the position of Fig. 1, the stem 6 being received within the a slot 16. The key is now inserted in the key hole 21 and if the lock have a key-hole at its rear side, the key may be passed completely through the lock before the finger piece 7 is actuated to swing the the latter mode of procedure may be somewhat troublesome as the bit must of course he exactly positioned Within the thickness of the lock to permit it to swing. In removing the key the several steps above enumerated are repeated in reverse order.
7 What I claim is: V
- l. A key of the class described comprising a slotted shank, a bit pivoted within a slotted portion of the shank, a slide connected to the bit for swinging the latter to lie Wholly Within the slotted part of the shank, said slide having a finger piece projectin'g laterally from the shank, and a guard forcovering the slotted part of the shank when the bit is retracted.
2. A key of the class described c01np ris-' ing a shank havinga transverse opemng,
a bit pivoted Within the opening, a vslide connected vvith the bit, stem projecting from the slide provided with a finger piece spaced "from the outer surface of the shank,
and a' guard sleeve embracing the shank and normally covering the blt recelving opening, said guard sleeve having a longitudi- V nally extending slot provided with a flaring end for the reception oi? the stem of the finger piece as the guard 1s retracted.
3. A; key of the class described-comprising a tubular shank having a longitudinally extending axial chamber, the Wall of the chamber being slotted near its o osite ends, a slide arranged within the chamber nearone end, a bit pivoted to swing Within the otherend' of the chamber and to be projected through the adjacent slot in its Wall, a link connecting the slide andbit',
a finger piece projecting from the slide 7 through the adjacent slot in the Wall "0f the chamber, and a guard sleeve enibracmg the shank and normally'coveriiigthe' slot through which the 'bitis projected.
