.Patented Dec. 8, 1914.

Application mea January so, 1914.- 'fserial Nu. 4815,505.

To all whom 'it may concern? Y Be it known that I, MARK F. RICHARDSON, a citizen of the United States, and a resident of Leonia, in the county of Bergen and State of New Jersey, have invented a new and lmproved Door-Lock, of which the following is a full, clear, and exact description..

The object of the invention is to provide a new and improved door lock arranged normally to hold the door securely locked against accidental opening and permitting of unlocking the door from one face thereof by pressure applied in a transverse direction instead ofturning a door knob or the like, and to allow unlocking from the other face of the door on pulling the door knob.

In order to accomplish the desired result use is made of a bolt mounted to swing into and out of locking position relative to the keeper in the door jamb, a locking lever normally engaging the said bolt to hold the latter in locking position, and manuallycontrolled actuating means on each face of the door and adapted to impart a swinging motion to the said locking lever to unlock the said bolt.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectionalside elevation of the door lock as applied, the section being on the line 1-1 of Fig. 2; Fig. 2 is a sectional view of the same on the line 2-2 of Fig. l; Fig. 3 is asimilar view of the same with the door partly open; Fig. 4 is 'View of the means for loc a transverse section of the same on the line -4 4 of Fig. 2; Fig. 5 is a sectional view of the same with the parts in position afterathe door is swung open; Fi 6' is va sectional g the actuating plate against movement, the section being on the line 6--6 of Fig. 4;I.Fig. 7 is a sectional side elevation of the same; Fig. 8 is a sectional view of the keeper and the bolt-actuating means mounted therein, the section being on the line 8 8 of Fig. 1. Fig. 9 is a side elevation partly in section of the door lock provided with a key-controlled mechanism for locking the knob .against sliding movement; and Fig. 10 is a sectional view of the same on the line 10'-10 of Fig. 9.

The door A is provided with a mortise for the reception of the lock casing B in which is mounted a vertically-disposed*` pivot C- -rided with a handle H 'carrying a bolt C adapted to engage with its free end a keeper D held in a mortise in the door jamb E. The bolt C is provided on the top and bottom and forward of the pivot C with cams C2 adapted to be engaged by sidewise-extending pins F held on arms F fulcrumed at F2 on the keeper D and extending within the mortise of the door jamb E. Springs Fs held on the keeper D press the free ends of the arms F to normally hold the latter and consequently the pins F in outermost position so that the pins F project into the path of the cams C2 when the door A is swung into closed position.,

The inward movement of the arms F is limited by stops D arranged on the keeper D.

The bolt C is engaged by a retractile spring C8 attached to the casing B and the said bolt C is provided opposite the pivot C with an oiiset C4 adapted to be engaged by one end of a lever G mounted to swing on a vertical pivot G arranged within the casing B. vThe other end of the lever G is pressed on by a spring G2 held in the casing B and the said end is engaged by a member H in the form of a plate extending transrersely throu h the back of the lock casing,

B and throug the door A beyond the inner ace thereof, as plainly indicated in Figs. 2, 3, 4 and 5. The member or plate H is attached to the inner face of a plate or arm H fulcrumed at its lower end at H2 on the 'outer face of the door A, as plainly shown in Fig. 4, and the upper end of the said'arm H is pressed on by a spring H8 interposed between the outer face of the door and the arm H, thus holding the arm H normally in an outward position, as shown in Fig. 4, and therebyallowing the lever G to engage the bolt C and its lug C* with a view to lock the bolt C in locking position, that is, at the time it engages the eeper D. The outward swinging movement of the arm is limited by a suitable stop H4 held on the door A (see Fig. 4), and the arm H is preferably proadapted to be taken hold of by the user.

When the door is locked as shown in Figs. 1 and 2 and a person exerts pressure on the arm H and swings the same inward toward the face of the door, then the plate H imparts a swinging motion to the locking lever G whereby the latter swings out of engagement with the bolt C, thus releasing the latter and allowing the same to swin laterally by the action of its spring C8.

SSOOII now swung shut the pins F engage vthe-cams- C2 whereby an outward swinging movement is: given-,tothefbblt yCso Athat theV latter swings into the keeper-D, and as the pres-` sure on the locking lever G is now released' .it is evident that thelever G rengages the boltC atthe offset C1 thus holding the bolt C-inlocking position, as shown .in Figs. l and 2.

In order-to vpermit opening of the door from-the-innen face thereof, the following# arrangement is made: The inner end of the lever Gis-engaged by a lug I projecting sidewise from 4a block I mounted to slide transversely in ai suitable bearing B arranged in the casing B. The inner end of the spindleJ of the door knob J -is secured'` to the ysaid block I, as plainly indicated in-Fig 2, and the shank of the said door knob yJ is: mounted vto slide in a suitable escutcheon K attached to the' inner face 'of the door A.- The knob J is provided at itsshank with' a pinl J2 engaging a slot K in the escutcheon K (see Figs. 4 'and 10) tb preventfthe door knob J from being turned- 'Now' when the several parts arev in' locked position, as shown in Figs.l 1 and 2,'and a person-pulls on the knob J then an inward' sliding movement is given to; thefblocli-I` which by :the lug I imparts fa swinging-motion'to the locking. -lever G so"that the latter releases thebolt C to allow the' door to swing openbyfthe pull exerted on-theknob day'thearrangement described the door when swung sh'ut is locked in closed position by the bolt2 C' swinging finto= engagement with thekeeper-D thus holding the-door against acidental'- opening. When it is desired tofopen-thedoo'r froid-the. outside then it is only'necessary to'eXe'rt' pressure on the arm' I-I'wlereby the fbo'lt C -isunlocked as' previ'ously explainedg and4 the 'door is swung* openibyf the eXertionfof-the pressure on 4the arm Incase thel'oeked' door is 'to"be opened from the inside it is only-necessary foraiperson to ull on the knob J whereby the bolt C dor'swin'gs 'open by I'the pull: exerted on the'kn'obJ. i

shownn the drawings,' the plate'H is mounted on the outerface of the door A and the knob: J #is located 'on 'the inner .face of the door,v but it is 'evident that the positions othe'plate H and the' knob 'J '-can be reversed: "Thus 'for inward' swinging doors, such'as lare used'- inl dwellings, the arrangement is as shown in the drawings, and for outward swinging doors, such as are used A in schools, theaters and other public buildings the positions of the plate H and thev knob J are reversed, as shown in Figs. 9

'and ,1.0.

The plate H and the arm H may be locked against movementand for this purpose the plate H is provided with an aperture H6 (see Fig. 4) adapted to be engaged by a pin L held on the lower end of an arm L fulcrumed at its .upper end at L2 in the casing B, as plainly shown in Figs. 4 and 7. The arm L is provided with a transverse rod L3 extending through a slot B2 in the front of the lock casing B, see Fig. 6, 'and the forward end of the pin Lais engaged by thehead N of a sliding catch N. mounted to slide in a suitable casing N2 secured to the inner face ofthe door A, as plainly shown lin Figs. 4 and 6. Normally the pin L is out of engagement with the aperture H6, but when it is desired to lock the plateH andthe arm H against movement then the operator slides the catch N from the left to the right so as to impart a swinging-motion to the arm L with a view to engage the pin L with the aperture H, thus locking the plate H against transverse movement. Itis understood that the locking of the plate H and the arm H does not interfere with the actuating of the lever G on pulling of the knob J as the knob .movement and the movement of the arm H the plate H, the outer face of the door.A

and the casing B, the bit of the key being adapted to-e'ngage a lug L4 on the arm L (see Figs. 1, 4: and 7). By the insertion of From the -foregomg 1t will lloe-seen that the key O and turning it, the arm L is swung out of engagement with the plate H', thus allowing opening of the door from the outside on subsequently pressing the plate H toward the door A. y

In case the door swings outward and the positions of the arm H and the knob J are reversed, as shown in Figs. 9 and 10, then use is made of akey-controlled locking device for the knob J, and for this purpose use is made of a vertical arm P pivotedv at its upper end at P on the lock casing. B and the-said arm .is adapted to engage a notch l' 'I Ivi-frmed in the block I tohold the block ecomes released and the ',side on pulling the knob'J, by the user manipulating the handle VP2 tol engage -the arm P withthe notch I2. The arm P is s'i'dapte'dnto be swung into unlocking positi'ii f "latively to theV block I by the use of 'y R adapted to be inserted into a keyhole of akeyhole plate S attached to the door at the ou'ter face thereof. Now when the arm P is moved into locking position relatively to the block Il by a person manipulating the handle P2 as above described, the door cannot be unlocked by a person pulling on the knob J but a person on inserting a key R and turning the same causes the arm P to swing out of locking engagement with the block I to allow opening of the door on a Isubsequent pull on the door knob J, as above described.

I Ihe door lock shown and described is very simple and durable in construction and its parts are not easily liable to get out of der- Having thus described my invention, I clain) as new and desire to secure by Letters atent: p l
