' Application filed April 10, 1906. Serial No. 310,929.

.To all whom it may concern:

Be it known that I, HENRY FRANCIS KEIL, a citizen of the United States of America, and a resident of Bronxville, in the county of Westchester and State of New York, have invented a certain new and useful Lock, of which the following is a specification, the same being a full, clear, and exact description of the invention, such as will enable those skilled in the art to which it appertains to make and use the same.

My invention relates to appliances for. se curing in position doors and like movable articles, and in particular to looks and 1,5 latches, adapted to be inserted in a notch. or

recess in the stile of a door, having an eX- pansible combined escutcheons and lock-face provided with means to expand the same, and which embody certain novel features of construction and combination and arrangement. of parts, of simple construction and cilicient in operation, all of which will be hereinafterdescribed and fully illustrated in the drawings. I

To attain the desired end, this, my invention consists in the construction, arrangement and operation of parts herein set forth.

In order to enable the invention to be fully mulerstood i will proceed to explain the ao'same by reference to the drawii'igs, illustrative of one embodiment of the invention, which accompany and form a part of this specification, and in which Figure represents a perspective view of my lock iittcd to a thick door; Fig. 2 is a clan view of the lock, Fig. 3 is a front view 0 the same; Fig. 4 is a side elevation; Fig. 5 is a vertical section through the handle; Fig. (l is a rear view with the lock casercmoved: Fig. 7

10 is a plan view of another lock in which. my

invention is embodied; Fig. 8 is a view in detail of the means for adjusting the expansion of thelock-face and Fig 9 is a View of a portion of the blank from which the device is formed up, the lines on which it is bent being shown or indicated by dotted lines.

Like letters of reference indicate like parts in all the views.

Referring particularly by letter to the drawings A, A, denote my combined escutcheon plates and lock-face which rests against the siilcs of a door. and extends around its front edge and preferably overlaps the notch and which is preferably made of sheet metal. The combined escutchcon plates A and lock-face A is of unitary construction, so far as itsfunction in supporting Within the same the lock case D (whiclrcoxitains a suitable lock or latch mechanismrand in serving as a covering for the notch or recess is concerned, may be considered as an entirety no matter whether it is integral and 'is made of a single piece of metal as shown in Figs. 1 to 6, or whether it is composed of a plurality of plates rigidly fastened together, as illustrated -in Fig. 7. B designates the knobs, and B, the shanks of the same which preferably incltise the spindle or lock-rod and ordinarily pass through the preferably loose hubs or roses B ordinarily carried by. the escutcheoii plates, and rest against the sides of the lock-case D, which is a complete arti ole of itself consisting of the body at and cap d, and is supported within the combined escutcheons and lock-face by means of screws d inserted into the front of the lock-case through the lock face A The lock-case D is inserted into a recess, notch or mortise 0 formed in the edge of the door preferabl by simply sawing a piece out to the depth 0 the lock, and the top and bottom edges a, a, (or, as it were, notch overlap ing edges (1 of the esoutchcon plates A am extensions thereof projecting toward the loclcfaee, and edges to of the locleface A) being of greater dimensions or size than the opening or recess C in the door, overlap the same as shown in Figs. 3 and 4, and thereby entirely cover or frame in the mortise and conceal any possible poor cutting out of the door, in the event of the same being carelessly or hastily done.

The top and bottom edges (.0, 1., also serve to afford resistance flanges or borders or sto )S, in order to prevent any danger of the lock from being pulled out of its position to any degree, or any, lateral displacement thereof, or the bending or the straining of any of the parts, inasmuch as the length of the frame A A being greater in distance than or pull on the handles it -the lock-face A,

also serving to support the lock-case. The lock casing is formed at its forward portion with preferably solid projecting lugs or abutmcnts made with orifices for the screws E and d, and ordinarily of greater thickness present a pract' :allyunbro ken edge than the rest of the casing so as to extend outwardly from the sides thereof as shown in Figs. 2 and 7.

The combined. escutcheons and lock-face not only forms a protection to the wood of the door, but the said structure is very readily applied and quickly attached to the door by simply slipping the combined escutcheons and lock-face over the edge of the door and thereby inserting the lock in the notch or recess cut out of the stile and then screwing the escutcheons to the sides of the door in the proper applied position by means of the screws i41 This invention is applicable to all kinds of doors to which mortise or rim locks can be attached, and is manifestly applicable to both locks and latches, or a combination of the two.

I proi ide a simple means for adapting my combined escutcheons and loeleface, to be used for doors of different thicknesses which preterabl y consists in mal iiur the same so as to be expansible and adjustable as regards the width of the lock-face as, in the present embmliment, by forming the same with a plailed or folded loch-face (the folds (L2 of the same ordinarily lying between the loch-case and constructed and arranged to be expand- .ed by the said screws and thehcads of the screws I). Tim strips (1, are cut out from the top and bottom edges of each of the folds or plaits (If, which strips are bent toward each other so as to lie behind the loci: face and to V of the lock face adjacent to, and above and below, the said folds, and lying at right angles to the folds at the upper and lower extremities of the lock face. The shanks of the screws E work in threaded holes in the sides of the loc'-:-case and may be operated by a tool ins l in the orilices (15, formed in the extensions of the esr-ulchoons, by which means the adjustabiliiy or. degree of expansion of the loch-hush. mar be regulated.

in. r the ronibined es .-.utcheons and loclel'ace is applied to anarro'w door, as in Fig. .5, the (*Hlll between the folds aflwill be closed. but in the cvcntof the,structure being used in connerrlion with and, attached to a wide door, as in. Fig. l, the folds (1,, will be opened somewhat (the screws l) having been unscrewed) and after the combined scutchcons and lock-face is ad usted in position, the screws i) may be tightened so as to serve to hold, in connection with the. escutcheon screws i the entire structure rigidlymupon the door.

l. wish it to be understood that i do not desire to be limited to the exact details of construction shown. and described, for obvious modifications will occur to a person skilled in the art.
