(01. vo-zo) My invention relates to certain novel improvements in a combined handle and lock and has for its principal object the provision of an im-. proved construction of this character which will be highly efllcient in use and economical in manufacture.

Without myself to the use or application of my combined handle and lock, in order to illustrate the advancment which I have made over the 'artrelating thereto, I makereference hereinafter to the use and application of. my invention to the door of a locker such as is employed in school buildings, workshops, oilices and other like places.

' With this in mind, one of the salient objects ofthe invention is to provide a combined handle and lock, the latter of which will control the operation of latch lifting mechanism operable by the hand of the operator upon graspingthe go handle and exerting a slight upward pressure upon the lifting mechanism to lift' the latch bolt or plate from its keeper plate or opening.

A still further object of the invention is to provide a combined handle and lock which is self- 26 locking upon closing of the door withwhich it is associated.

A still further object of the invention is to provide a loclathe mechanism of which may be independently operated by either a permutation 30 "lock or a master key. i

A still further object of the invention is the provision of a combinedtlock and handle which.

when associated with a door having a liftable latch bolt or plate, operates in -a plane parallel with the movement of the l tch bolt or plate thepart of the lifting mechanism and/or the latch boltor plate thereby avoiding undue wear as well aspermitting the lifting mechanism to be operated by a'minim'um pressure of the hand against the lifting mechanism thereby eliminating the possibility of the latch bolt or plate and its lifting mechanism being thrown out of alignment with respect to each other and with respect to the keeper plate.

A. still further object of the invention is the provision of lifting means for a latch plate or f member which is in direct connection with the 7' latch plate or member thereby assuring efficient 50 and expeditious operation of the entire mech- Other objects will appearhereinafter.

The invention will best be understood by reference to the accompanying drawings, showing the 55 preferred form of construction and in which;

i, 7 Construction inner face of this flange is a plate or latch bar I2. 40

This .connection between the plate I: and flange I i is accomplished in the usual manner by means of slot and pin connections I3.

At predetermined points upon this plate II are provided spaced latch fingers It adapted for engagement with keeper plates l5 secured to the adjacent side jamb it of the cabinet or locker.

Secured to the plate I! is a laterally extending arm i'l having formed therein an opening i8 which is disposed in registration with an elongated slot l9 formedin the door.

The plate I! and arm I 'I are associated with v the door in the manner above explained so as to gravitate into position to dispose the latch fingers II in latched engagement with the keeper 5 plates l5 when the door is in completely closed position.

I have selected a door of this structure to illustrate the advantages and utility of my improved combined handle and lock.

My improved combined handle and. look as shown particularly in its preferred form of con: struction in Figs. 1 to 6, inclusive includes a handle 28 the upper end of which is formed to provide a casing or housing 2| within which the lock mechanism to be presently described is confined.

To completethe handle there are provided extended portions or ears 22 and 22 which are perforated as at 22' fonthe passage of connecting elements 24 preferably in the form of nut receiving 1101a.

These connecting elements 24 are utilized for connecting the handle to the door III as best. showninFigs'.'7and 8.

The rear portion of the casing or housing 2| is open and when the lock mechanism is assembled therein this open rear portion is normally closed by a plate 25, parallel to" which is slidably arranged a lift" 28.

This 11a :6 includes a horizontally extending portion 21 at its lower end, and from which lower end also extends a web or'latch'portion 28 for reasons hereinafter-more fully understood.

"u and arranged inthis Extending-laterally from the lift 28 is a pin 28 which is adapted for operative projection through the elongated slot I 8 formed-in the door. the inner end of the pin 28 fitting into ing |8 of the arm I1 of-the plate l2.

The lock mechanism is obviously concerned with the locking of this lift 28 against operation and this mechanism will now be described in detail the open- The casing 21 in its front wan is provided with 40 -'an opening 28; Rotatably mounted in this open-' ing 28 isa knob 21 having a beveled body portion 22 which bears a dial 22 including numerical characters and indicating lines 24.

The knob 2| is provided with an annular flange "which is arranged within the opening 28 and extends around the marginal edge 28 of the latter (Fig. 3). a

Formed integrally with the knob 2| is a sleeve sleeve 21 is a barrel 'or cylinder 28.

V Secured to the closure plate 25, as by rivets 25'. is a supporting structure 28 from which is supported the barrel 28 as shown at. Mounted upon this barrel 28 forwardly of the supporting structure plate 38 are the permutation discs 4|. The discs 4| are of the usual well known construction and include the combination changing rings or keys 42 together with the means 42' for rotating the permutation discs about the barrel 28 so as to permit operation of the lift upon-placing the permutation discs in proper registration pursuant to a predetermined rotatlve movement of the dial 2|22.

Hie peripheral edges of the discs 4| are provided with notched out portions to provide a shoulder '42 into which is adapted to be engaged a spring urged pawl 44 which is pivotaliy mounted on the lift 28 as best shown in Figs. 5, 5', 6' and 8!. The function of this pawl which is normally urged by a spring 88 in a counterclockwise direction. Figs. 8 and G's-will bemade more apparent hereinafter.

Pivotally supported by the supporting structure 88 is a member 45 which has formed therein at member 45 is urged, by a spring 85, Fig. 6 in a direction (clockwise, Fig. 6) to project its lateral extension 41 into the notches 48 inthe discs 4| when the latter are registeredwith each other.

Formed in the lift 28 is an elongated slot 28' through which a pin ill-which is supported by the plate 25 projects, and pivotally supported by this pin 58 is a latch arm 5|.

This latch arm 8| is normally urged by a spring 58' (Fig. 6") into position to dispose the lower end portion 52' thereof into obstructing position or latching engagement with respect to the web or latch portion 28 of the lift 28.

The latch arm 5| includes an upper end portion 52 and this upper end portion 52 of the latch member 5| includes a shoulder 52 which is normally disposed, by action of the spring 88', in a position to engage an extended portion 54 of the pivotal member 45, for reasons which will be best understood hereinafter.

The upper endportion52 of the latch member 5| is provided with a concave shoulder or recess 55 which is adapted to be engaged by the nose portion or rise 58 of a cam 51 which is mounted upon a shaft portion or extension 58 of a lock cylinder or barrel 58, which is rotatably mounted within the lock cylinder 28 and within which a plurality of tumblers 88 are mounted, these tumblers 88 being-codified to a service or master key 8| which controls the operation of the lock cylinder 58 and consequently the operation of the shaft 58, as best shown in Fig. 3. g

' The lift 28 is normally urged into a lowered position with respect to the supporting plate 28 by means of a spring 82 'whichis supported upon the plate 25 by a pin 88, one end portion 84' of the spring 82 being disposed over the upper end portion 84 of the lift 28 as best shown in Fig. 8 Carried by the lift 28-and projecting laterally therefrom is a pin 82' which is adapted to engage in the recess 48 which is formed in'the pivotal member 45, for a reason to be explained presently.

of Fig.8a with its nose portion or rise 58 extending upwardly and the lift 28 and the latch pin 28 carried thereby are normally prevented from being raised or lifted, to effect the door unlatching operation, by reason of the fact that the lower end portion 82' of the pivoted latch member 5| is normally disposed directly above the transverse web or stop portion 28 of the lift 28, as shown in Figs. 6 and 611. However, as will.now be described, the operator may move the lower end portion 52' of the latch member 5| out of vertical alignment with the stop portion 28 of the lift 28 in either of two ways, that is, either by manipulating the combination knob and dial 2 |-24 and the permutation discs 4| into position to register the notches 48 in the discs 4| with each other; or; by insertand the permutation discs 4|, are manipulated 15"" into position to register the notches so in the permutation discs 4| with each other, ,the spring 85 acts upon the member 45 to pivot the latter (counterclockwise, Fig. 60;) so as to move the projecting portion 41 of the member .48. into the registered or aligned notches 48 in the permutation discs 4|. v

During this movement of the pivotal member 45 (counterclockwise, Fig. 6a) the lower end portion 54 thereof engages the upper end portion 52 of the latch member 5| and pivots the latter against the action of its resetting spring 88', (clockwise, Fig. 6a) so as to dispose the lower end a portion 52 of the member 5| out of ,alignment with the transverse web or stop portion 28 of the lift 28, (as in Fig. 6b) thereby permitting the lift 28 to be raised; and when the lift 28 is lowered,

or. reset into its initial position, the spring 88' tion of Fig. 6a to its position of Fig. 617) so as to dispose thelower end portion 52' thereof out of I alignment-with the stop portion or web 28 of the lift,28 by insertinga proper key 8| into the lock cylinder or barrel 5! and then turning the same v and the shaft 58 and cam 51 (clockwise, Fig. 6a)

This movement of the lock cylinder 58, shaft 58 v and cam 51 (clockwise, Fig. 6a) causes the nose portion or rise 58 of the-cam 51 to engage the shoulder 53 which is formed in the upper end portion 54 of the latch member 5|, thereby pivoting the latch member 5| (clockwise, Fig. (in) so as to dispose the lower end portion 52' thereof out of alignment with the web or stop portion 28 of the lift. 28 so that the latter may be lifted. The key 8| may then be manipulated so as to turn the lock cylinder 58 shaft 58, and cam 51 (in a counterclockwise direction, Fig. 6a) back'into their initialpositions. when the permutation discs 4| are manipulated, bythe knob and dial 3l34, into position to register the notches 48 therein, the notches 43 in the permutation discs 4| are also registered. Accordingly, after the lift 28 has been raised, to perform the door-unlatching operation, and is being returned by gravity to its lowered position,

the spring 88 acts upon the pivotal member or pawl 44, which is carried by the lift 28, to urge the lateral extension 81 of the member .44 into en- "gagement with the peripheral edges of the discs 4 I thereby disposing'the extension 81 of the mem her in the aligned notches 48 which are formed I clockwise direction, Fig. 6a).

in the peripheral edges of the permutation discs 4|, as shown in Fig. 50. As they lift 28 continues.

its downward movement, the lateral extension 81 of the member 44, engaging in the notched portions 48 of the permutation discs 4|, turns the latter (clockwise, Figs. 5 and 5a) whereupon the cam edges 13 of the discs 4| which define one marginal wall or edge of the notched portions 48 (Fig. 5a), engage the lateral extension 41- of the member 45 and therebypivot the member 45 (in a movement of the member 45 moves the later thereof out of the notches 48 in the permutation discs 4|, whereupon the discs are rotated or moved further, in a clockwise direction, Fig. 5d,

by the lateral extension 81 of the pawl 44. In this manner the relative positions of the discs 4| are changed, that is, the notches 48 are moved out of registration with each other, and with the '|4 on the slide bar |2 into latching engagement extension 41 lateral extension 41 of the member 45, and the combination is destroyed or scattered, so that the device can not again be operated by means of the dial 8 8, until the permutation discs 4| are again manipulated, by a person knowing the proper 5 combination, into position to register the notches 48 with each other and with the lateral extension 41 of the latch member 48.

During the downward movement of the lift 28 the pin 88' carried thereby engages in the recessed portion 48 of the pivotal member 45 and thereby pivots the latter (clockwise, Figs. 6' and 6a) so as to dispose its end portion 54 out of engagement with the shoulder 53 of thelatch 5|.

It is to be noted, however, that even though the 15 device can not again be operated, by means of the knob 3|, until thesame is operated by a per son knowing the proper combination, it may, nevertheless, be operated by the insertion of a proper key 8| into the lock cylinder or barrel 88. 2 Attached to the door l8 on the inner side of the latter is a piece of flat spring metal 88 which has an angled upper end portion 18 and this angled upper end portion 18 of the member 88 is engageable when the door I8 is in opened position, with a serrated edge portion 1| which is provided in the slide bar l2 so as to hold the slide bar |2 in raised position when the door I8 is open, and likewise holding the main latch member or lift 28 in effective or latching posi tion, when the door I8 is in opened position. However, when thedoor i8 is closed an angled end portion 12 of one of the keeper plates l5 (Fig. 9) engages'the angled end portion 18 of the latch member 88 and forces the angled end portion18 of the latch member 88 out of latching engagement with the serrated edge portion 1| of the slide bar l2, thereby permitting the slide bar l2 to drop by gravity and thus moving the lugs 40 with the keeper plates l5, (Fig. 9).

This downward movement of the slide bar l2 acts upon the pin 29 to move the latter downwardly in the slot l8 (Fig. -9) which is formed in'the face plate of the door "I, thereby lowering'the lift or latch member 28 into its lowered or effective positiomwhereu'pon the spring 88' moves-the latch member 5| into position to dis* pose the lower end portion 52' thereof above the upper end of the-web or stop portion 28 of the latch'member or lift 28 so as to prevent unauthorized movement of the latter.

It is to be noted that when the lower end portion 52' of the latch member 5|. is moved out of. latching engagement with the latch portion or r. web 28 of the lift 28, either by means of the key 8| or the dial-bearing knob 3|, the lift 28 may be raised so as to lift the latch bar |2 by-merely grasping the handle 28 and exerting an upward pressure on the lower end portion 21 of the .lift (30 28 by means of the index finger, it being noted that the lower end portion 21 of the lift 28 is disposed within the confines of the handlev 28 and that the handle 28 remains stationary relative to the door I 8 during this operation of raising the 05 lift 28.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the 70 spirit of the invention, I, therefore, do not wish to be limited to the precise details of construction set' forth, but desire to avail myself of such variations and modifications -as come within the scope of the appended claims.
