SPECIFICATION forming part of Letters Patent waves,- dated March 1,1904? Application filed March 17, 903. v Serial No. 143,222. (No modeL) To all whom it may concern: I

Be it known that I, JAMES E. YOUNG, a citizen of the United States, residing .at Wayland, in the county of Steuben and State of New York, have invented new and useful Improvements in a Combined Lock and Latch, of which the following is aspecification.

My invention relates to .improvements in combined locks and latches, and pertains more particularly to that class including a nightlatch.

The object of my inventionjis to provide a combined lock and latch which can be used as an ordinary latch operated by a knob and is provided with means for locking the same in an outward position, and thus serves as a positive lock for the door. The said latch-locking mechanism is adapted to be locked in or out of engagement with the latch from the inside or may be held in such a position that the normal tendency thereof would be to hold the latch in an outward position, but said mechanism when in such a position being adapted to be operated by a key from the outside of the door. .1 r 1 Another object of my invention -is to provide a combined lock and latch of this character which can be readily attached. to the ordinary door and which is i more simple, cheap, and durable than locks of this character heretofore produced.

In the accompanying drawings, Figure 1 is a perspective view of a portion of the door,

showing my combinedlock and latch attached thereto. Fig. 2 is a horizontal sectional view taken on line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view taken on line 3 3 of Fig. 1.

Fig. 4 is a top plan view of the sliding bolt and the knobs operating mechanism. Fig. 5 is an enlarged plan view of the mechanism operated by the key by means of which the latch-locking mechanism is released. Fig. 6 is a vertical sectional view taken on line 4: 4 of Fig. 1. tion of the sliding bolt and operating mechanism. 7

Referring now to the drawings, A represents that portion of the door to which locks Fig. 7 is an enlarged side eleva of this character are attached, and the edge thereof is provided with a horizontal round elongated recess a, into which fits the sliding latch B, which isof acorresponding shape,

although this forms nogpart of myinvention,

as said recess a could be square and the latch or bolt, of acorresponding shape. The said latch or bolt B is of a length less than that of the recess-a 'and has its .outer end beveled at b and the inner end reduced at b, and;said reduced portion is adapted to enter a coiled spring C, which is located at the inner end of the recess a. The normal tendency of said spring is to hold the said latch in an outward position, and thus serves as a latch for holding the door closed. The said, sliding latch or bolt B is provided with a vertical cut-away,

portion B between its ends and is also provided With an elongated horizontal transverse 'slot D "adjacent the rear end thereof andthrough which the knob-spindle E is adapted to pass, thus allowing for the free inward movement of the sliding latch or bolt B. The said knob-spindle E carries the usual knobs E and E by means of which the sliding bolt or latch Bis drawn inwardly, which Iwill now proceed to describe. The said bolt or latch B, having cut-away portions B adjacent the rear end, forms a vertical shoulder or ledge B and the knob-spindle E is provided intermediate its ends with laterally-extending oppositely-an ranged wings Fand F, which have their rear edges beveled at f and f and said beveled portions of said wings are adapted to engage the shoulder B and thus the turning of the knobspindle E through the medium of the knobs E and E in either direction will cause the latch or sliding bolt B to be drawn inwardly,

against the tension of the spring. To prevent the knob-spindle from being turned too far in either direction, I provide the wingsF and F with notches or recesses f" and f which are adapted to engage the upper and;

lowerportions, respectively, of the lug G, carriedliby the said sliding bolt r latch B. Y The said lug G is so positioned on the member B that the turning of the knob-spindle, which throws the bolt rearwardly, will bring said lug belowor above the outer end of one of the wings F and F, according to the direction the knob is turned.

The door is provided with an enlarged transverse opening a, which allows of the free removal of the knob-spindle E, and thus the bolt B can be removed when desired. The end of said opening a is covered by the circular plates H and H, which also form bearings for the said knob-spindle to turn in.

The door adjacentthe edgeand a little above the sliding bolt isiorovided with an elongated vertical recess I, which communicates with the upper portion of the recess a, and below said recess a is a second key-opening a, through which the key is adapted to be inserted, and the inner endis enlarged at i for the purpose of allowing the enlarged end of the key to be turned after inserted, the purpose of which will be hereinafter fully described. The inside'of the door is provided with a slight recess J, which is preferably of an elongated form and surrounds the two recesses I and 17, and covering said recess is a plate K, which is preferably secured to the side of the door by screws, although any desired means might be used. The upper end of the plate K is provided with a vertical elongated slot k, and vertically adjustable in said slot is is ahorizontally-arranged squared member L, which extends into the vertical cut-away portion or recess I in the door A. The said cut-away portion or recess I communicates with the horizontal recess a and is so positioned that when the bolt B is in its normal or outwardlypressed position the notch or recess M in the bolt B is directly therebelow, and thus the member L is by gravity held therein or locked therein, as hereinafter more fully described. The bolt or squared member L on the inside of the plate K carries a plate N, which extends downwardly adjacent the key-opening and is thus adapted to be raised by the key, which in turn raises the bolt or squared member out of the recess in the sliding bolt B, and thus allows the same to be turned by the knob-spindle, as heretofore described. The said.downwardly-extending member is preferably of the construction shown-that is, with two downwardly-extending arms 92 and n, the member a being shorter and broader than the member 12, while the member a is provided at its extreme lower end with a laterally-extending member m and thus the key only acts when turned in one direction and that is on the lower end of the arm n. The said squared member L on the outside of the plate K is screw-threaded at Z, and fitting on said screwthreadcd portion is a thumb-screw O, which is adapted to clamp the rod or member L in the slot of the plate K at the adjusted position, and the lock is made a positive lock, which can only be operated from the inside, or when the thumb-nutis left loose it can be raised by a key, heretofore described, or the member L can be locked in the upper part of the slot of the plate K, and thus the device is adapted to be used as a latch only.
