DOOR LOCK Filed April 6, 1942 Patented Mar. 7, 1944 UNITED STATES PATENT OFFICE DOOR LOCK Matthew Spinello, Rockford, Ill.

Application April 6, 1942, Serial No. 437,774

Claims. (01. 70-462) This invention relates to door locks and more particularly bore type locks, which are so-called because the transverse holes in the door made to receive the lock can be bored with an auger bit and there is very little mortising necessary.

One of the principal objects of my invention is to provide a lock of the kind mentioned which is quickly and easily convertible to suit right or left hand use and to change from a spring latch to a dead bolt, to suit requirements.

A salient feature of the lock of my invention consists in the provision of a detachable bracket carrying the operating finger arranged to be applied to the inner end of the bolt housing on either side, depending upon what side of the door is the outer side onto which the barrel of the lock is to be applied, the bolt housing itself being rotatable about its longitudinal axis, and the aforesaid bracket being applicable thereto from the top or bottom, whereby to adapt the lock to a right or left hand door.

Another important object of my invention is to provide a lock in which the bolt has a cam plate attached thereto with a pin and slot connection and operable by the aforesaid operating finger to move the bolt in either direction, the bolt housing carrying a spring pressed catch, which engages in notches in the bolt to hold it positively in either extreme position, the catch being arranged to be cammed out of the way by the aforesaid plate upon movement of the operating finger, thus providing a lock in which the bolt is tamper-proof, being securely held extended or retracted, although movable with the operating finger very smoothly and easily in either direction. Removal of the spring pressed catch and insertion of a spring to hold the bolt normally extended are the only things which it is necessary to do to convert the dead bolt to a spring latch.

The invention is illustrated in the accompanying drawing. in which- Figure 1 is a view looking at the free edge of a door equipped with a lock made in accordance with my invention, a portion of the door and lock being shown in section to better illustrate the invention;

Fig. 2 is a side view of the bolt housing removed from the door and showing the bracket and operating finger assembly mounted thereon;

Fig. 3 is an inside view of the bolt housing, the removable housing side plate having been removed;

' Figs. 3a and 3b"correspond to a portion of Fig, 3, but show the parts in moved positions to illustrate the camming out of the way of the catch in the movement of the bolt in both directions;

Fig. 4 is a cross-section on the line 4--4 of Fig. 2, indicating in dotted lines one of three other possible positions of assembling the detachable bracket and operating finger assembly, and

Fig. 5 is a view similar to Fig. 3 with the catch removed and a spring inserted to convert the dead bolt of Fig. 3 to a spring latch,

The same reference numerals are applied to corresponding parts throughout the views.

Referring to Fig. l, the reference numeral 5 designates a door in which the transverse holes I and 8 are bored with anger bits to receive the lock of my invention, designated generally by the reference numeral 9. III is the bolt reciprocable in the generally cylindrical housing H received in the hole I and fastened in place in the usual way by the escutcheon plate I! in a recess I3 mortised in the edge of the door. A side plate It forming substantially half of the housing H is removably secured in place by a screw l5 threading in a hole in the neck l6 provided inside the housing. The bolt II) is guided for reciprocation in the housing I l in the bearings l1 and I8 and has a lost motion connection with an elongated cam plate l9 by means of pin projections 20 on the bolt slidable in slots 2| in the plate. There are two cam surfaces 22 and 23 on the lower edge of the plate l9 in longitudinally spaced relation. These cam surfaces are for actuating a catch 24 that is pivoted on the neck l5 and has 9. lug 25 projecting laterally from the free end thereof for engagement in either one of two longitudinally spaced notches 26 and 21 provided in the bottom of the bolt Ill. A coiled compression spring 28 seated at one end in the housing and having its other end fitted over 9. lug 29 projecting downwardly from the catch 24 serves to urge the catch normally into engagement with the bolt.

In operation, the bolt M can be moved in either direction by means of the cam plate is. In retracting the bolt from the extended position shown in Fig. 3, the cam surface 23 in the initial movement of the plate l9 releases the catch, as shown in Fig. 3a,, and then the bolt is, of

.course, free to move inwardly relative to the housing I I. At the end of the inward movement, the lug 25 on the catch 24 engages in the notch 21', thus locking the bolt positively in retracted position. Thereafter when the bolt is to be extended, the initial outward movement of the cam plate l9 causes release 01 the catch 24 by cooperation of the cam surface 22 with the lug 25 in the manner shown in Fig. 3b. After release of the catch 24, the bolt I0 is of course free to move with the plate It, similarly as in retracting the bolt. The operation is smooth and easy both ways, and it should be clear that the catch locks the bolt positively in either extreme position and the bolt is therefore tamper-proof.

The bolt ID has a tubular guide portion ex- Lending inwardly -.therefrom and having .a free telescoping .flt on .apin 3| mounted in :the .housing H and extending longitudinally thereof. When it is desired to convert the dead bolt" shown in Fig. 3 to a spring latch, as shown in Fig. 5, the only changes necessary are the rcmoval of the catch 24 with its spring ZBandthe provision of a long coiled compression spring 32 in the housing II acting between .tlrelhonsing and bolt, as shown in Fig. 5. The guide. forms a. convenient mounting for the spring '32. In operation, this. spring latch permitsslammingzthe door with the bolt projecting, but, .of course, it requires the operation of the inside knob 433, or the key 34 on the outside of the .dOl',B.SWill soon appear, to retract the bolt so that the .door :can be opened.

The bolt housing ll fits freely in the hole I bored in the door 6 and is adapted to be turned through 180 to havethebeveled face 35. on .the outer end of the bolt I0 face one way for right hand operation, as it appears in :Fig. 1, and in the opposite direction for left hand operation. The operating finger 36 is pivotallymounted by means of a bushing 31 on aibra'cket .SBarranged to be detachably mounted on the bolt housing H in either one of two bearings .39 and 40 sprovided on oppositegsides .thereof. The bearing-4.0 is formed as apartof the side plate IA. The bracket 38 can .be mounted .in .either .of';these bearings from either end, thereby enabling the assembling of the operating finger 35 withits forked end ll straddling the cross-pin l2 onithe inner end of the .cam plate 19 .ineither one-oi four positions to'suit either aright .or left hand door, and in either ofthose instances theiplacing of the cylinder lock 43 on the innernr'onter side of the door. Theinnerend'of theLh'ousing H has a. diametrically extending :opening JMi'to permit entryofithe finger "36 from .elther side for connection of the fork ll .withithe'pin I2. The bracket 38 will, .:of course, beiassembled on the housing ll. afterithe latter has beententered in the hole I. That .can bexdone easiiythrongh the larger transversej hole ill, .as should :be apparent from inspection of: Figs 1, the housing ll having its inneri'endpnoiecting into thei'holesa to the extent indicatedfor easy entryofttthe operating finger '36 zdowniinto the :opening 14 to connect with .the pin 12 at ithe .sameiflmetthat the bracket 38 is entered inithe bearingm or? as the casemay Jae. .It' is ."manifest, therefore, that to installthis'lock'thecarpenter can quickly and easily adapt it .tothe speciflcinequirements of the job inhand, hecausethe look iauniversa'lly adaptable. There. is 'noneed'fon thecsuppiy house to keepright and left handed locks in stock. Consequentlyithere 11s a :savingain roost sandfithe likelihood of confusion and I delays :is avoided.

The cylinder lock;.indiicatedltfl3,is of conventional design'and construction alfd is adaptew to be entered: insane sendzordzhefhole 8=a1-ten an escutcheon ring 'llirhas :beempressed. errdriven into thatzend iihfl'ieihble. fl'heiiobk measured in place fromzthe :JSiflBfif-lthE-QOOWW Til one 01' which is indicated at 41 in Fig. l, are extended and threaded in ears 48 on the inner end of the body 49 of the lock 43. The cylinder 50 of the lock, which turns with the key 34, has a loose lost motion connection at El with a stub shaft 62 of square cross-section. The knob 33 has a square bore 53 in its shank portion snugly receiving the other end of the shaft 52 and, as clearly appears in Fig. 1, the shank portion of 2 the knob 33 is rotatably mounted in the escutcheon ,plate 46. Now, the shaft 52 is connected intermediate its ends with the operating finger -36 by entry through the square hole 54 in the bushing 31, whereby to oscillate the operating finger in the turning of the shaft by means of the .knob 33 orkey 34. The lost motion at 5| permits 90 turning of the shaft 52 independently of the cylinder 50 as required in unlocking the door from the inner side. There is sufiicient play also at the connection 5| so that the knob 33 does not have to be exactly aligned with .the cylinder 50 and :the axis of the cylinder may be at a slight angle .to' the axis of the knob. In that wayithe lock will operate smoothly and easily and there will be no tendencyto bind, even if there is a certain amount of misalignment. The fact that the-operating finger 36has its operated end 55 in offset parallel relation to the forked end ll .to the extent shown in Figs. 1 and 4, the supporting bracket 3B.having its outer end 56 likewise offset from its supported ,end 51, .enables the close coupled relationship illustratedbetween the lock 43 and bolt housing .ll;an,d in that way .the lock 43 can bev placedsubstantialiy flush with the outside of the door, leaving little or nothing exposed on which a burglar can work in :attemptingto break in. In many other locks with whichI am familiar, .the escutcheon plate on: the outside of the door had to be of anembossed .design approximately to the extent of the offset of the portion 55 with respect toithe portion '41 of the operating finger 36. Such an embossed escutcheon plate invites tampering. The offset in the bracket 38 is incidentally .ofiadvantage in 7 providing the intermediatebea'ring portion 58.
