LOCK.

Application filed September The `lock is particularly applicable to front doors, and comprises thumb latch means, and key and knob operated means to retract a single draw bolt.

It is prefeable in so called front door locks to provide the door on the outside with a handle, thumb vlatch draw bolt retracting means and key ope ated draw bolt retracting` means; and on the inside with knob operated draw bolt retrac'ting means.'

An object of my invention is-to provide a novel lock of this character the draw bolt of which maybe independently retracted either by a knob, key, or a thumb latch.

An object is to provide a novel lock of this character in which each one of thediaw bolt rctracting means is operable, irrespective of whether or not the other retracting means are rigidly held in normal position.

'Another object is to provide a novel lock of this character, in which one or all of the draw bolt retracting means may be securely lockedA from the inside of the door.

A further object is to provide a novel lock of this character in which the thumb latch means may be locked from the inside of the door and still permit retraction of the draw bolt by operation of either the knob or key operated retracting means.

Further objects are to provide a lock which is simple in construction, inexpensive to manufacture, andeflicient in operation.

Advantages of my invention are to provide a. lock, the body of which may be formed in a single casting, 4and which may be quickly and easily installed in a door.A

This application includes certain novel features more particularly shown and described in my copending application filed August 3l, 1925, Serial Number 63,548; and may be said to apply the key and knob op; erated lock shown in said application to a front door.

@ther objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the. appended claims,

The acconxpanying drawing illustrates the invention.

VFig. l() is an end view of the key operated draw bolt retracting member.

To prepare the door or the like A, to receive my novel lock l provide the same with a transverse bore B, and with a bore C that extends from the bore B, at right angles to the axis thereof, to the free or outer edge D of the door, and ai recess E which depends from, and communicates with, the bore B, and extends vertically in such door at right angles to the axis of the bore C.

My invention comprises a tubular locll body i. which is mounted in the bore B and said body l has an externally threadedex# tension 2 on one side thereof. The extension 2 .is preferably cast integral with the body l but it is understood that the Vsame maybe a separate part more clearly set forth in my above referred to copending application.

Thumb latch supporting means in the form of a tube 23 depends from the body l and is adapted to be received in` the recess E. The `tube 3 may be threaded to the body 'l or it may be preferable to die cast the tube 3 integral with the lock body l and extension 2.

A draw bolt 4 is provided at its inner end with a crosshead Ll and said draw bolt in cludes a sleeve 5 which extends toward the free edge D of the door and is 4journalled in an orifice 5" formed in the body l. The crosshead 4 and sleeve V5 is providedwith a bore 6 in which )in 7 is adapted to slide ingly lit. The pini? is provided with a reduced end 7 vthat extends through the body 1 and is riveted over at its outer end to secure the pin to the body 1. The pin 7 serves to support the draw bolt 4 `and Iacts as a 'guide for the saine. A compression spring 8 surrounds the pin T and operates between the ci'osshead 4 and lock body and tends to normally hold the draw bolt in latching position.

The draw bolt also includes Ia latch member tha-t is formed with a threaded shank 10 which is threaded into vthe sleeve 5 a predetermined distance so that the latch member extends trom the tree edge oft the door a sutlicient distance. A rguide plug 11 is driven into the outer end ot the bore C -iiush with the edge D to close said bore, -and said plug is provided with an opening 12 in which the latch member 9 is adapted to slide. The outer periphery ot' the Iplug 11 is serrated as at 13, so 'that the plug 12 will not accidentally protrude beyond lthe :free edge D of tlie door.

Knob operated draw bolt retracting means f 14 is provided to retract the draw bolt from the inside of the door and such means coinprises a -disc 15 'formed on the inner end of an oscillating shaft 16 which entends from the disc 115 land is jou'rnalled in the eXtension 2. The disc 15 is mounted between the closed rend ot the lock body 1 Vand the crosshead 4 and is yot sufficient thickness to fill the space therebetween so lthat end play of the shaft 16 is .practicallyY eliminated.

The outer Iend of the shai't 16 may lbe reduced in diameter if desired and yis threaded as at 17 to receive a 'handle 18 which bea-rs against the shoulder 19 't'ormed by reducing the outer end of 'shai't 16.

An arcuate lug 20 formed on the disc 15 projects inwardly therefrom and the crosshead 4 rests against both ends of said lug' under pressure xo't ithe spring 8. As the shaft 1.6 is oscillated either to the right or left by the fhafndle 18 one end of the lug 20 w-ill Jforce lthe crosshead 4 against the tension Iot spring 8 and thereby retract the draw bolt 4.

Key operated draw bolt retracting means is provided to retract vthe draw bolt troni the outside of the door and comprise a cylindrical key lock 21 which is screwed into the bodav 1 in axial a-linement with the shaft 16. A disc 22 having an arcuate :lug'23 similar to disc 15 and lug 2() is secured to the key operated tumbler 21 ot the lock 21.

The ends ot the lug 23 rest against lthe crosshead 4 in the same 'manner .as before described in connection with the lug 20. lh en `the tumbler .21 is oscil-lated the dra-w bolt 4 will be retracted, irrespective of whether or not the handle 18 is rigidly held.

-A cover plate 24 is secured to the inside of the -door by any suitable means. such as screws 25, and the shaft 16 Iextends therethrough. A clamp nut 26 is threaded onto the extension 2 and has a shoulder 26 that bears against the plate 24.

An outside cover plate 27 is secured to the outside yot the door A by lany suitable -mea-ns such as 'screws 28 and lis provided with an orifice 27 through which the key lock 21 protrudes. A sleeve 29 threaded onto said lock bears against the plate 27 and clamps the door between the shoulder 26 and the inner end ot said sleeve 29 and thus positions and iirmly holds the lock body 1 in the bore B.

A bolt 30 threaded into the plate 27 eX- tends through the tube 3 adjacentthe lower end thereotland nuts 30 threaded to said bolt 30 on opposite sides ot the tube serve vto position and hold the tube in rigid position. A suitable handle 31 ot any desirable contour or shape by means ot' which the door may be swung is secured to the plate 27 by a nut 31. Y

Thumb latch draw bolt retracting means are provided to retract the draw bolt irrespective ot' the knob or lrey operated retracting means and comprise a thumb .piece 32 pivotally mounted between ears 33 formed on the inner side ot plate 27, a stem 34 that extends inwardly 'trom the thumb piece 32 into a slot '35 formed in the tube 3. A wedge block 36 is slidably mounted in the tube 3, and rests by gravity against the stem 34. A iller plate F is secured Ato the tube 3 by rivets G and torms a bearing block against which the wedge block 36 slides.

The vupper surface of the block 36 is inclined at an angle a-s at 37` Fig. 4, the purpose of which will be further described.

A finger 38 is pivotal-ly mounted in the tube 3 on a pin 39 which extends through the tube 3 and is riveted thereto. The upper end ot the linger 38 engages the crosshead 4. while the lower end thereof is provided with a roller 40 which rests against the surface 37. Spacing members H retain the linger 38 in a central position in the tube 3.

lvl-ien the thumb .piece 32 vis depressed vthe stern 34 will move the block 36 upwardly and the surface 37 will engage the roller 40 and torce the finger 38 to -fmove to the dotted line position shown in 'Fig 4 and thus retract the draw 4bolt 4.

The thumb piece will operate to actuate the cross head member entirely independently of the knob 18 or key lock 21.

It desired the thumb latch retracting means may be locked from the inside of the door, against operation` by means ot a loelring pin 41. which is journalled in the tube 3. and projects through the plate One end oli lthe pin 41 is provided with a head a to prevent. withdrawal of the pin 41 and the other end of the pin 41 lis flattened as at b to receive aV linger 42 which has a sliding lit with said flattened end. The iinger 42 is rotatably mounted in plate 24 and l (ll) lli) is secured thereon by a collar a which has a drive fit on a shank 0 formed on the linger 42, and provides means whereby said pin il may be` rotated.

`A recess 43 is provided in the pin il to receive lthe linger `38 when the linger 58 is moved to retract the draw bolt.. By rotating the pin 4l to move the receee 43 away from the linger 38, the solid portion of the pin 4l is moved into `the p: th ot the linger 38 and will prevent movement oil the ling ,r on its'pivot. The pin tl it will be noted only controls the operation oi' the thumb latch re tracting means and the draw bolt may be retracted by either the knob or key operated retracting means.

However, I also provide means controlled from the inside oi' the door whereby the draw bolt may be looked against operation by `any of the hereinbefore mentioned retracting means, and auch locking' means coinprise a lock bolt 44 iouinalled m the body l adjacent to and extending through a portion of the sleeve 5. The lock bolt 4d is identical to that shown in my copendint;` mgplication and is provided at one end Wfth a head tt' to prevent withdrawal. and at its other end with a flattened portion e that extentie through the plate Q4- and ie adapted to slidingly receive a linger 45 which provides means whereby the lock bolt tl may be rorated. The finger 45 ie identical in conetruction and assembly to the finger The sleeve 5 is provided with a transverse notch lo into Whichthe pin 44 is adapted to be rotated to thereby prevent reti1A ction oit the draw bolt.

The lock bolt 44 provided with a recess1 47 which is adapted to normally accommodate the sleeve 5 and permit :tree movement of the sleeve therethrough.

y rotating' the lock bolt id to bring the recess 4i' out oi' alin-ement with the Sleeve 5. the body of said pin is presiented to said sleeve and enters the notch etti' in said sleeve to lock the same as described.

The operation and assembly of my invention will be apparent from the foregoing de- Seription.
