Specification of Letters Patent.
Patented Sept. 30 1913.
Application filed March 27, 1913. Serial No. 757,223.
To all whom it may concern:
Be it known that I, FRANK M. DoUeHrY, a citizen of the United States, residing at Bronson, in the county of Bourbon and State of Kansas, have invented certain new and useful Improvements in Locks; 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.
This invention relates toimprovements in looks and particularly to the key-holes and keys of locks.
One obj eot of the invention is to provide a lockcasing having an improved construction and arrangement of key-hole provided with baiiling devices which will positively prevent the insertion of any key except the one designed to enter the same.
Another object is to provide a key-hole of this character which may be used in connection with any kind of door or case lock and to provide a key constructed to enter the lock.
With these and other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be more fully described and claimed.
In the accompanying drawings: Figure l is a side viewof one side of a lock having my improved key-hole; Fig. '2 is a similar view of the opposite side of the lock; Fig. 3 is a central vertical section through a portion of the lock casing and the key-hole therein; Fig. 4 is a vertical sectional view taken on the line 4-4 of Fig. 3; Fig. 5 is a detail perspective view of one of the disks or plates of the keyhole; Fig. 6 is a detail perspective view of the key employed with my improved key-hole; Figs. 7 8 and 9 are detail vertical sectional views of the key hole and a portion of the lock casing showing the position the parts assume as the key is being inserted into the lock; Fig. 10 is a view similar to Fig. 3 showing a slightly modified form of spring for holding the movable bafliing devices of the key-hole in operative position.
Referring more particularly to the drawing, 1 denotes a lock casing in which may be arranged any suitable form of lock mechanism. The casing comprises side plates 2 in which at the point where the key is usually inserted are formed alined circular apertures 3 in which are revolubly mounted circular key-hole disks or plates 4 and 5. The disks 4 and 5 are recessed on their outer sides at their edges to fit into the apertures 3 and to form annular shoulders or flanges 6 which bear against the inner surfaces of the side plates 2.
The disks 4 and 5 are fastened together and held in position in the apertures 3 by a centrally disposed bolt 7 the ends of which are engaged with or fastened in the centers of the disks 4 and 5 as shown. When thus arranged and connected the disks are adapted to be turned together in the apertures 3 of the sides 2 of the lock casing when the key is engaged with the lock in the manner hereinafter described. Each of the disks 4 and 5 has formed therein near the upper portion thereof segmental slots 8 one or more of which may be arranged in the form of a circle and spaced suitable distances apart in each of the disks or as herein shown the slotin each disk may be continuous to form almost acomplete circle, the ends of the slots terminating a short distance from each other to form a narrow tongue 9 of metal between the ends of the slots as shown. The slots 8 are also offset at one or more .points and in opposite directions as shown at 10. One end of the segmental slot 8 in each of the plates is continued outwardly or radially for a suitable distance in the disks as shown at 11 and said radial extension of the slot is oifset in opposite directions or of irregular formation as shown at 12.
Secured rigidly to and spaced a suitable distance apart on the bolt 7 are small right angular laterally projecting guide bolts or rods 13 having headed outer ends. There may be one or more pairs of bolts 13 and they may project in any desired direction from the bolt 7. In the present instance only one pair of bolts 13 is shown and they are illustrated as projecting upwardly from the bolt 7. Loosely mounted on the bolts 13 is a ward or detent 14 in the form of a flat bar having its ends offset to form stop shoulders 15, said ofiset ends being beveled on their outer edges as shown at 16 for a purpose hereinafter described. The bar or detent 14 is provided near its oiiset ends with longitudinal slots with which the headed ends of the bolts 13 are engaged for loosely attaching the detent to the bolt 7. The detent 14 is yieldingly held in a projected position and in spaced relation to the bolt 7 by a spring 17 which is arranged between the bolt 7 and the inner side of the bar lt. The spring 17 is preferably a coiled spring as shown in the first figures of the drawing but if desired a flat leaf spring 18 maybe- 111130 the look as described.
provided instead of a coiled spring as shown in Fig. 10 of the drawings.
In connection wit-h my improved key-hole I provide a key 19 constructed or designed to be inserted in the key-hole and which comprises a tubular body portion 20 having on one side thereof at its inner end a bit 21 which may be provided with any suitable construction and arrangement of wards 22 for engaging the levers or tumblers of the lock. The tubular body 20 of the key has a diameter corresponding to the diameter of the slots 8 in the disks t of the key-hole with which the key is designed to be engaged. The body of the key is also provided with longitudinal corrugations 23 which correspond to the oflt'sets 10 of the slots 8 and which permit the key to be inserted in the slots. The bit 21 is also provided with corrugations 24 which correspond to the ofisets or irregularities 12 in the slot 11 of the disks 4: with which the body is engaged when the key is inserted in the key-hole. In the end of the keyare formed one or more longitudinal recesses 25 which extend inwardly a short distance beyond the inner end of the bit 21 and which are designed to permit the key to pass the uncut parts or tongues 9 of the disks between the ends of the segmental slots 8. As hereinbefore stated the slots 8 may be divided into several short slots thus forming a series of tongues 9 and when thus constructed the key will have a corresponding number of recesses'25 to engage said tongues as will be readily understood. Also formed in the end of the key are one or more short notches 26 which are provided to receive the offset end or shoulder 15 of the ward or detent 14 when the key is inserted in the lock and which permit the key to be inserted all the way so that the bit 21 will pass entirely through the slot 11 in the disk to permit the key to be turned in the look as clearly shown in Fig. 9 of the drawing.
lVhen inserting the key in the look the end of the key after passing through the slot in the disk on the side of the lock with which the key is applied will engage the beveled surface of the adjacent offset end of the ward or detent 14 and will depress this end of the detent as clearly shown in Figs. 7 and 8 of the drawing. The depression of this end of the detent against the pressure of the spring 17 or 18 will permit the key to be inserted over the detent until the shoulder 15 formed on this end of the detent were it not that the end of the key is provided with the notch or notches 26 which are disposed in proper position to receive the shoulder 15.
This engagement of the notch 26 with the shoulder or ofl'set end of the detent will permit the key to be inserted all the way has thus been inserted the same together with the disks and parts attached thereto After the key 7 may be turned in the look'tobring the wards 7 foregoing 7 It will also be seenthat a the lock neither can the same be readily picked by any instrument. a
From the foregoing description taken in connection with the accompanying drawings, the construetion'and operation ofthe invention will be readily understood without requiring a more extended explanation;
Various changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed. I
Having thus described my invention, what I claim is 7 V 1. In a look, a casing having therein circular apertures, keyhole plates revolubly mounted in said apertures and having therein segmental slots and radial slots, said slots being oifset in opposite directions, a bolt to connect and hold said plates in operative engagement with the apertu-resin the lock casing, guide bolts arranged on said plate connecting bolt, a detent comprising a bar having therein longitudinal slots to receive the ends of said guide bolts, offset beveled ends formed on said detent to provide stop shoulders, a spring arranged between said detent and said plate connecting bolt whereby the detent is yieldingly held in spaced relation to said bolt and in position to form a stop or obstruction to the insertion of any but the proper key and a key constructed and designed -for engagement with the slots in said key-hole plates and with said detent. a
, 2. In a look, a casing having therein alined circular apertures, key-hole plates revolubly mounted in said apertures and having therein irregular segmental slots and irregular radial slots, flanges formed on said plates to engage the inner side of the lock casing, a bolt to connect said plates and hold the same in operative engagement with the look casing, a. spring projected detent arranged between said plates,a key having a tubular body provided with longitudinal recesses and notches, and longitudlnal corrugations corresponding to the irregularities in and the spaces between the ends of the segmental slots in said key-hole plates whereby the key may be engaged with said slots and with the detent between said plates, a bit arranged on the key and having corrugations corresponding to the corrugations in the radial slots .in said key-hole plates whereby the bit may be inserted through said radial slots and to permit the key to be turned in the lock.
3. In a lock, a casing, slotted key-hole plates revolubly mounted in said casing and having therein key receiving slots, a detent arranged between said plates, a key comprising a tubular body provided with longitudinal recesses and notches and having therein longitudinal corrugations, and a corrugatedbit arranged on the body of the key, said tubular body and bit of the key corresponding to the shape and construction of the slots in said key-hole plates and adapted to be engaged therewith and with the detent arranged between the plates.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
