' LOCK. 5.. APPLICATION FILED MAR. 24. m3. Patented July 16, 1918;





To all whom it may concern:

Be it known thatl, GEORGE E. CLEAVER, citizen of the Unitcd-States,=and resident of Reading, county of Berks, and State of Pennsylvania,- h-ave invented an Improve ment in Locks, of which the following is a specification.

My invention has particular reference to that class of locks in which a'single key is employed to operate both the latch bolt and the dead bolt; and consists of many features of construction and combinations of parts adapted for giving tothe lock capacity for more effective operation, all. of which are fully set out hereinafter and more particularlv define: in the claims. I

My improvements will be described with reference to the accompanying drawings,

which illustrate my invention in. its pre-.

ferred form, as a reversible mortise lock, of CYlll'KlQT'bYPG and antifriction form.

Referring to the drawings: Figure 1 1s a front end view of my improved lock applied to a doorand showing the handles, key and turn knob; Fig. 2 isa side elevation of the lock proper .withsideplate and key cylinder removed and the front plate in section; Fig. 8 is a transverse section of my'impr'oved lock on line 00-00 of'Fig. 2; Fig. 4: is a transverse section of the same on line 2 y of Fig. 2; Fig. 5 is a transverse section of the same on line 22 of'Fig. 2; Fig. 6 isa plan view of the turn knob cylinder removed and with the cap plate removed to show the interior construction; Fig. 7 is a cross sectionofthe same on line s--s of Fig. 6; Fig. 8 is a perspective view of the dead bolt and cylinder engaging lever; and Fig. 9 is a cross section of a portion of the case and an elevation of the cylinder engaging lever.

2 is the box portion of the case and is secured to the front plate 3, through which the bolts are shot. Thev open side of the case 2 isclosed by a removable side plate a (Figs. 3, l and 5). 5 is the dead bolt and is provided at its rear end with the slot .7 and the talons 9 and 10 with a tumbler space between them, and a notch 19 in front of the forward talon. The slotted portion 7 fits over a guide lug 8 extending from the case 2 and acts to guide the rear end of the dead bolt. 11 is a tumbler, hinged at 12 -tion (Fig.2)

the notch 17 (Fig. 8), will cause the bolt to Specification of Letters Patent. Patented J uly 16, 1918. Application filed. March 24, 1913. Serial No. 756,366.

Arranged under the dead bolt and pivoted to the case 2 at 15, is the-roll-back engaging lever 14, the construction of which is best shown in Fig. 8, constituting a lever having the arm 16, the notch 17 and the finger 17.

As shown in Fig. 8, the side of the dead bolt 5 is provided with a lug 18, which at times operates to'holdthe lever 1% against oscillaand at other times, when in be shifted by action of the lever ltwhen actuated by the cylinder mechanism.

lii is the key cylinder and may be of any suitable construction; it is screwed into the side plate 1 and provided at its. inner end with the operating cam 47 which is arranged to coact with'the talons 9 and 10 of the dead bolt, thetumbler 11, and the roll-back engaging lever 14 above referred to. Ar-

ranged in the opposite part of the case, is

the unit turn knob cylinder 48, also screwed,

into'the case to secure adjustable attachment, and having the cam 49 for operating upon the parts 9, 1O, 11 and 14, this operation taking place from the turn knob 56 (Fig. 1).

The end 16 of the roll-back engaging lever 14 coacts with the latch lever 20, pivoted to thecase at 21, to rock it and thereby withdraw the latch bolt 6 against the. action of its spring 38. The end of the latch lever 20 engages with the transverse. end 22 of the latch bolt (Figs. 2 and 5), said CODStll Cf'; .tion permitting the latch bolt tobe reversed,

as hereinafter described. With the parts above described and as shown in Fig. 2, it will'be seen that the lever 14 is held in gear by the dead bolt, which passes Over it in such manner that the lever is in range of .the cylinder cam 47 until suflicient protraction' of the dead bolt carries it away as intended; or vice versa. This is necessary for those cases where the dead bolt might be unintentionally or unnecessarily partly protracted or retracted by the turn knob mechanism, sothat the cylinder cam may be enabled to act to protract the bolt totally by getting against the rear auxiliary shoulder 9 of the'rear'talon, or retract the bolt by contact with the upturned. arm 14 of the said lever '14' which is held 'by the bolt,

'(while in motion) in position for contact, as

long as the said rear shoulder 9 is not sufliciently forward to be used. It w1ll be understood that in the normal or usual way of" turning the cylinder cam 47 or turn hub cam 49 against the end of the lever 14, both it and the latch lever will be tumbled and the latch 6 retracted. The finger 17 of the lever 14 is prevented from getting out of position vwhile the dead ,bolt 5 is retracted,

because of the lug 18 of the dead bolt. It

will be seen thattheibolt may bemoved forward ,a distance, a little greater than the length ofthis lug 18, before the lever 14 can possibly rotate'to get its upper end out of range with the cylinder cam. In this position, the lug 18 enters the notch 17 as shown in Fig. 8 and, striking against the lever 14,

' oscillates it out of reach of the cylinder cam.

In the reverse movement, should the bolt 5 be only partly retracted, this action will cause the lug '18 to press against the finger 17 andoscillatethe lever 14 to the position substantially asshown in Fig. 2, preferably before the retraction is half way completed, and in which position the cylmder cam may reach and operate the lever -l4vto retract the latch bolt '6," and at the same time, by the action of this lever upon the .lug, force the dead bolt fully'back to its retracted position as shown. The lever '14 then, when released returns to the position shown in Fig. 2 under the action of the latch bolt. In this way, not only may the dead bolt be operated in the usual way, but provision is made -to properly project and retract it from intermediate and unintentional positions into which it may accidentally'be brought.

The turn knob cylinder 48 is shallow and recessed as at '57 and covered with a-plate or cap 5 8 which maybe secured in place by screws or rivets or many suitable manner. The interior of the cylinder isprovided at the upper end with a horse-shoe shaped recess 61 provided for receiving a looped end 61' of a wirespring 60 andholding it invposition. This wire spring-60 has downwardly eXtendingfree'pa-rallel ends and bends '60 V to lengthen the wire of the spring and give more elasticity, therebypermitting a stronger wire to be employed-than if the spring were shorter. Thewire composing this springall lies in the same plane and consequently takes very little space, thereby permittinga very shallow cylinder 48-to be employed. .The free ends of the spring 60 press upon the flattened sides ofthe turn hub and socketz59 which is journale'dl-in the cylinder-and secured on its outerend with the camor operating bar ,49, previously referred to. The

turn knob 56 (Fig. 1) may have the usual square shank to fit'the square hole in the hub and socket 59. When the turn knob is rotated,it rotates the socket 59 and cam 49 to operate the latch bolt when the dead bolt lever, may be considered as a material portion of my invention. The special objectjof this lever 14, other than its action upon the latch lever, is to clear everything, with its upturned end l4 sweeping the full inside of the case, so as to obtain the benefit of ad- 7 justment of the cylinders to the full value ofthe width inside of the case. As far as I am aware, such constructionof lever has not heretofore been employed where a turn hub and cam are operated from a point within the cylinder hole of the case.

As both the key cylinder 46 and turnhub cylinder 48 are required to be held against rotating when .once adjusted, I provide set screws 50 for this purpose, said screws being so secured to the case that they cannot'be- .come accidentally disengaged and lost. In

the construction shown, these set screws 50 are screwed through threaded bosses 51,011 the case parts ,2 and 4 and provided with pointed ends to engage V.-shaped notches in the cylinders, said screws being further providedwith collars 52 at a distance from their slotted ends, which are :held between shoul- V .ders 53 on the case parts 2 and 4 andthe front plate 3. The ends of. the screws 50 extend into holes 54 in the end plate 3 so as to enable them to be rotated by a screw driver. There is sufficient space between the shoulders 54 and the front plate in which the collars 52 may move to enable the set screws to be fully withdrawn from the cylinder 3 before contacting with the'frontplate. In thisway the threaded. end andhe'ads of the set screws are prevented from getting out of their respective cooperating holes,

thereby preventing the losing ofthe screws inside the lock or separating therefrom.

Referring now to the latch. bolt v6 and" its associated parts: Thelatch bolt b0dy29 is made with an opencslot and is fitted with a rod or guide tube 30 of rolled or drawn .metal thereby providingasmooth guide at :low cost. This guide tube or. rod 30is held .in place by having one end fitted to a pro- -jection 30 and the otherend received in a recess and held therein by having the lug 30 bent over. it (Figs..2 and5.),.

it-is not essentialto have the knobs independent .in action and hence it is tobe understoodthat, if desired, the two knob hub.

parts maybe cast integraland a solidspindle employed, as is common in the cheaper looks.

I have, in the .preferred construction, shown the roll-back engaging lever 14 in a form which will positively-assist in fully retracting the dead bolt, should it be only partly retracted from any'cause, as well as for operatingthe latch bolt.

I have shown my improved lockhin the specific form which. I have found. most satisfactory impractice, but Ido not restrict myself to the details shown as they maybe modified in various ways without departing from the spirit of the invention, as defined in the claims. I
