By referring to Figs. 1 and 10 it willbe noted that the opposite ends of the spindle housing are threaded and that these threaded ends project beyond the inner and outer faces of the door A. These projecting ends are provided with screw threads to receive on the outer face of the door a head member, generally indicated at E and on the inner side of the door an escutcheon plate F. The head member E is provided with a handle G thereby permitting the lock as a whole to function as a frontdoor lock, but this handle is not essential as the head member E could be shaped in the form of a knob, see the dotted lines II, so that a pull can be exerted to open the door as-will hereinafter lie-described. The knob. indicated in dotted lines will, however, only function in the manner of a drawer knob or pull as it cannot be rotated. The ordinary door 'knob H secured on the inner end of the spindle is however rotatable to rotate the spindleand thereby to retract the latch bolt.
The mechanism so far described is substantially identical to that disclosed in my former patent heretofore referred to, and for that reason has been only briefly described. The present invention relates almost entirely to mechanism which is placed within the tubular spindle D. This mechanism, briefly stated, comprises a key actuated mechanism, generally indicated at J,vsee Fig. 2, disposed in the outer end of the tubular spindle, which may vbe longitudinally moved within the spindle by manual operation to cause retraction of the latch bolt 6, thus making it possible to retract the latch bolt by merely applying thumb pressure to the endof the key mechanism,` or in other words, to permit it to function as a pushr button, which, when depressed by thumb action, will permit opening of the door. Thisv key mechanism is also rotatable by insertion of the key, and when key rotated I dog the key mechanism against operation eX- cept by insertion of the Vkey as the key mechanism may berotated even though it is dogged against Alongitudinal movement.
The key mechanism specifically described comprises a tubular housing generally indicated at I4, see Figs. 2 and 9. The inner end of this housing has a lug I5 formed thereon on which is mounted a pin I6. This pin extends into a slot I1 formed in one end of the tubular spindle housing, see Fig. 10, and thereby secures the housing I4 Yagainst rotation,butat the same time permitting longitudinal movement thereof. Mounted within the housing I4 is a cylinder key plug I8, see Fig. 7', which carries a series of tumblers |86 and which also has a key way formed therein. This key way is open at the outer end to permit insertion of a key I9, see Figs. 1 and 2, and the inner end is provided with a lug 20, the function of which will hereinafter be described, also a pin is secured in the plug at the point indicated vat 2|, and this pin extends into'anv opening 22; see Fig. `12,'soas to permit the plug when rotated to transmit rotation to plug may be rotated with relation to the housing I4, but when the key is removed the tumblers will project into said slot 14a. and the plug will then be secured against rotation.` A cap 23 is applied to the outer end of the tubular housing I4 andthis cap together with the outer end of the plug I8 forms a push button which functions as will hereinafter be described.
By referring to Figs. 2 and 14, it will be noted that a retractor lever 25 is disposed within the spindle just ahead of the lug `2l! formed on the inner end of the cylinder plug. This lever is pivoted on ,a pin 26 extending through and secured in the walls of the spindle. See the dotted lines 26 in Fig. I5. this point to permit introduction of the lever.' The inner end of the lever has a shoulder 21 formed thereon, and this shoulder engages the shoulder 8 of the retractor plate. 1
The function of the key mechanism and th lever is as follows:
1f it is desired to open the door from' theexterior it is only necessary to grasp the handle G and apply thumb pressure to the cap 23 and the outer end of the cylinder plug I8. This pres-` sure causes the entire key mechanism to move inwardly and as it moves inwardly the lug 20 engages the rear end of the retractor lever-25 and thereby swinging it about its pivot 26 and causing the forward end or shoulder 21 to engage the shoulder 8 of the retractor plate to force it` inwardly and thereby retract the latch bolt 6 when the door mayA be opened by pulling on the'handle G, .or theknob indicated in dotted lines at II. Upon releasing thumb Vpressure on the outer end of the key mechanism, spring I0 will return all parts to normal position.
A clogging member generally indicated at 3 0 and mounted adjacent the'free end of the lever 25 may be pushed inwardly to assume the position shown in Fig. 4' by means of a push button indicated at 3|, and when the dog assumes the position shown in Fig. 4, it will obviously be impossible to impart longitudinal movement to the key mechanism andthe key mechanism'is'fthus dogged against depression or push button action to open the` door.
as by inserting a key the tumblers will befwithdrawn from the slot |4a of the housing I4, vthus leavingV the cylinder plug I8 free to be 'rotated by the key, and when it is so rotated, pin 2| carried by the inner end of the 'cylinderplug will engage one or another of the shoulders 22a and the spindle thereby rotating it, such rotation causing the roll back member 9 of thegspindle to engage the shoulder 8 of the'retractor plate,
Also the spindle is slotted at It may, nevertheless, -be opened providing a person has the` properV key,
