AYE-AIL.

' lates more specifically I tions of the respective owners JOHN E. PATTERSON, 01E POUGHKEEPSIE, NEW YORK.

IDENTIFYING MEANS FOR NIGHT-LATCH KEYS.

a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Identifying Means for Night-Latch Keys; and 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. 1

This invention relates to keys, and it reto an improved identifying means for a night latch key or similar article.

One object of this invention is to provide a key with a plurality of superposed cards or the like on which the names of successive owners or users of the key may be written or otherwise aflixed to serve as identificaor users. Another object is to provide a device of this character embodying means of easy-access to a large portion of each card, so that a pointed instrument can be engaged with an obsolete card so as to remove the latter and thereby expose a previously concealed one of the cards and permit a name, number or other character or characters to be affixed on the newly exposed card.

Another object is to provide each card with a border or frame to which it is detachably connected by means of a series of fragile connecting elements so that it may be easily detached from its frame or border, leaving the latter in osition to aid in securing the other car 5 in their respective places.

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings, in which:

Figure 1 is a view of a key partly in side elevation and partly in section disclosing the topmost one of the identification sheets.

Fig. 2 is an enlarged transverse sectional View along the line 2-2 of Fig. 1.

Fig. 3 is an enlarged sectional view at right angles to Fig. 2, and disclosing the device after several have been removed. a

Fig. 4 is a perspective view illustrating one of the identification sheets or plates before it has been united with the body of the key.

Specification of Letters Yatent.

of the identification cards Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, the key \blade 5 may be of any appropriate construction, according to the lock to be operated thereby, and the key handle 6 may also be ofany appropriate or preferred contour as regards its relatively thin or convex sides. However, the major sides of the key handle are preferably plane with the exception of the central cavity 7 and the flanges 8 and 9 which extend over the margin of the bottom 10. The bottom 10 1s preferably plane and surrounded by end and

side walls

11 and 12 from the tops of which the flanges 8 and 9 extend, respectively, other words, the flanges 8 and 9 are parallel with and spaced from the respective end and side margins of the bottom 10.

A plurality of the identification sheets 13, (one of which is shown in Fig. 4), are

superposed within the cavity, as shown 1n 8. and 9, so that a name or number may be -written or otherwise aflixed upon the outer surface of the outermost card, the other cards being invisible and inaccessible because they are completely inclosed within the cavity 7 Each sheet 13 is provided with rows of perforations at the junction of the middle portion 15 and margin 14, and between these perforations are provided rows of fragile connecting elements 16 which are in registration with the inner edges of the flanges 8 and 9. One of the flanges 8 and the corresponding wall 11 is provided with a notch 17 which extends to the bottom of the cavity and provides means through which a sharppointed instrument may be inserted under the topmost card or through one of the perforations thereof so as to remove the topmost card when it becomes obsolete, thereby exposing a previously concealed card in position to receive a mark or character of identification.

The margin 14, however, is left within the cavity as shown in Fig. 3, and this margin coacts with the margins of the other sheets in holding the cards rigidly in place.

over the margin of the bottom 10. In f In forming the blank, the fiangesfi and 9 are primarily formed in a position at right angles to that illustrated in the drawings, so that the opening of the cavity is sufficiently large to receive the sheets 13; and after the Sheets have been placed on the bottom 10, the flanges 8 and 9 are passed behardened or stiffened by any appropriate means.

Although I have described this embodiment of my invention very specifically, it is not intended to limit this invention to theseexact details of construction and arrangement of parts, but I am entitled to pmake changes within the scope of the inventive-idea disclosed in the foregoing description and following claims.

What Iclaim as my invention is: 1,. device of the character described, comprising a body portlon having a cavity formed therein with projecting flanges extending around the margin of the said cavity, and a plurality of identification sheets superposed within said cavity and having their edges clamped between said flanges and body portion, a portion of each of said sheets being removable to expose and display a portion of the subjacent one of said sheets. 1

2. A device of the character described, comprising a body portion having a cavity formed therein with projectingflanges extending around the margin of said cavity and a plurality of identification sheets superposed within said cavity and having their edges clamped between said body pow tion and flanges, each of said sheets consisting of an identification card and a border around the card, said border being united with the card by rows of fragile connecting elements substantially in registration with the inner edges of the respective flanges, whereby apointed instrument may be engaged with said card and coact with said flanges to separate the topmost card from its border while the latter remains in its seat.

In testimony whereof I have hereunto set my hand.
