COMBINED HANDLE AND LATCH, KNOB AND CYLINDER, LOCK.

Application filed September 4, 1926. Serial No. 138,627.

not be tampered with from outside the closure.

A further object is to provide a latch lock construction in which the housing containing the operating parts of the lock is in fixed rigid relation to the handle and outside fin-.

ish of the look, so that the workman who installs the lock in its closure is not required to fit the parts together during the process of installation.

In carrying out this invention I employ elements of construction and features of arrangement that are described and claimed 2 in my Patents Nos. 1,629,764 and 1,617,001; in my applications, Serial No. 53,548, filed August 31, 1925; and certain applications filed on the 4th day of September, 1926, to wit :Serial No. 133,627; Serial No. 133,628; Serial No. 133,629; and Serial No. 133,630. A further object of the invention isto provide a construction and arrangement whereby a front door latch lock can be produced at a manufacturing cost many times below that 35. which is necessary for the production of front door locks of the construction now in common use. I 1

A further object is to make provision whereby the latch handle and the rigid parts of the lock are rigidly secured to each other and'to the face plate and to the closure when the installation is made, and to effect this result I provide a unitary housing forthe latch lock .operating mechanism and connect said housing to the finish plate-by a stud bolt connection, and screw the cylinder look into such housing and against a collar that engages the finish plate.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed dcscrip tion and the appended claims.

The accompanying drawings illustrate the invention.

Figure 1 is an outside view of a frontdoor latch lock constructed -in accordance with this invention and installed in a door closure. and jamb, fragments of which are shown partly in vertical section.

' Fig. 2 is an edge view looking from the right of Fig. 1, the door closure being shown in vertical section and the door jamb and strike are omitted:

Fig. 3 is an enlarged fragmental view showing in vertical section on line w, Figs. 1 and 4, the bolt operating parts of the latch lock and fragments of the handle installed in a closure.

Fig. 4 is a view of the latching lock installation looking toward the finish plate.

Fig. 5 is a front view of the lock housing "detached.

-. Fig. 6 is a front elevation of the housing viewed from line :0, Fig. 3, with the operative parts in lace.

The latch ever 1 is a lever of the first class fulcrumed at 2 to the bearing 3 which is an integral part of the face plate 4.

The

parts

1, 2, 3, and 4 may be of any standard construction and the external portion 5 of the handle may also be of any standard construction excepting that it is provided with studs 6, 6' which may be integral with the handle, and which extend through the

face plates

4 and 4*, respectively and are fastened by'any suitable means, as by screw threading the studs. and screwing nuts 7- thereonto and against a lock washer 8 of any suitable construction to prevent accidental working loose of the nut 7.

The face plate is also provided on the inner side with a projecting rod-or tie bolt, which may be positioned and held in different ways. One convenient way is to provide a threaded socket 9 into which a. tie bolt 10 is screwed to receive spacing nuts 11 and 12 for fixing the lower end of the elongate housing 13 relative to the face plate 4.

Said nuts 11 and 12 engage the back wall "of the housing 13 on sides thereof so that when the tie bolt 10 is screwed home in the socket 9 and the nut 11 is screwed to the proper position to hold the wall of the housing 13 at the proper distance from the facplate 4.

, The elongate housing 13 is provided on the side toward the face plate with a front wall 14 having at its lower end a slot 15 to accommodate the inner end 16 of the latch lever 1. The housing 13 also has side walls '17 and 18, and a vertical slideway 19 is thus provided for a member of the latch-boltoperating train of devices, here shown as the lever operated wedge 20 that is adaptedto act upon an antifrietion roller 21 journalled to a bolt operating lever 22 that is fulcrumed at 23 to the housing 13, and is arranged at its upper end to act against the tappet 24 to withdraw the latch bolt 25 from latching position, 9. (Fig. 1.)

It is thus seen that by pressing the outer end ofthe thumb lever 1, the wedge 20 will be shoved up to movethe latch operating lever 22 on its fulcrum 23 and cause the upper end of lever 22 to operate the bolt retracting means to withdraw the bolt from the position to engage the strike 27, that may be of any ordinary construction and attached to the door jamb 28.

The cylinder lock 29-which may be of any well known construction is secured to the door closure 30 by an internally threaded retaining sleeve 31 which is screwed onto the barrel 32 of the cylinder lock 29.

The thumb latch locking device comprises a locking ,pin 33 having a notch 34 and jour- -nalled in the housing 13 on that side of the latch operated lever 22 toward which a portion of the lever-adjacent the pin must be moved in order to cause said lever to retract its tappet 24. The notch34 of said pin is of such depth that when it is turned into the position shown in Fig. 6 itwill accommodate the lever 22, when the same is operated by the wedge 20, so that so long as the pin is turned in that position the latch 1 may be operated and will thus function through its inner end 16, the wedge 20 and the lever 22 to retract the tappet 24 and latch 25 connected thereto.

When the pin 33 is turned to bring its web into lever intercepting position, the thumb lever 1' cannot be operated; but the locking thus eflected does not interfere with the operation of the tappet 24 by the cylinder lock 29 which operates said tappet through the disk 35 provided with the cam 36 that acts upon the tappet to withdraw the bblt when the lock cylinder 29 is turned by the key 37.

An inner disk 38-provided with a cam 39 arranged to engage the tappet 24 to retract it against the spring 26 is connected through a -journal 40 with knob shank 41 on which is fixed the inside knob 42. 43 is the dead bolt locking p1n having a handle 44 on the, inside of the door,-and said lockingpin is described in my companion application for patent on tion Serial No. 133,632, filed on the 4th day H of September, 1926, for night latch.

Said dead bolt locking pin is notched in a manner corresponding to the latch pin 33 shown in Fig. 6 of this application, and the bolt connection 45 is notched to engage the web of the dead bolt locking pin 43 when said pin is turned to bring its web into the notch of the bolt connection.

The

locking pins

33 and 43 are operable by

handles

44 and 44 on the inside face of the door.

It is thus seen that the latch bolt can be locked from the inside of the door against operation either by the thumb latch lever, the key, or the knob.

It is also seen that a knob of any approved diameter may be applied to theiknob spindle 41 on the inside of the door.

The inside plate 46 carries the

levers

44 and 44 which are journalled therein in any suitable manner and a knob nut 47 is screwed onto the hub 48 that projects from the upper cylindrical portion 49 of the housing 13; and said inside face plate is secured to the closure by screws 50.

It will be seen that by reason of the disposition of the knob and key bolt-moving elements in line with the bolt on opposite sides of the housing and the disposition of the latch element for moving the bolt in the housing below the bolt, a very compact arrangement is provided with a minimum number of operating parts. The difi'erent actuating elements are quite independent of one another, so that no one is aifected by any movements of or derangements of another. The projecting spring for the bolt serves, through the independent connections, to restore always the parts to normal position, so that the necessity of independent restoring means for any of the parts is done away with.
