LATCH AND LOCK Filed May 2, 1947 2 Sheets-Sheet 2 Fig. 6.
u 3 \53 7677 4 6 A h 47 48 Inventor 46 Arthur Newell 3 to the edge 3 of the door I by means of the screws 44.
A spindle 45, which is approximately square or rectangular in cross section, extends transversely of the side plates 4| and 42 and through the door I, supporting the door knobs 46 and 41 upon the opposite ends thereof, while escutcheon plates or disks 48 and 49 are disposed about the spindle 45 between the outer surface of the door I and said door knobs 46 and 41, furnishing the trim for the said door knobs.
A pair of upper and lower locking bars or fingers 50 and are pivotally supported for vertical movement upon the pivot pins 52 and 53 between the side plates 4| and 42 adjacent their inner ends which are arcuately curved as at 54 and 55 towards each other at their inner ends, while their outer ends project through the vertically aligned openings 56 and 51 formed through the face plate 43 of the housing I. The inner ends of the rods or wires 35 and 36 are pivotally attached to the forward ends of the locking bars or fingers 55 and 5| whereby when said fingers 55) and 5| are spread apart, the'ball latches 25 and 26 will be simultaneously projected into latched position, and when said fingers 50 and 5| are moved towards each other, the ball latches 25 and 26 will be retracted to their unlatched position.
The inner edges of the fingers 50 and 5| will be notched out as at 58 and 59, and will cooperate with the rockable finger operating cam 65, which in turn is actuated by the cam actuating member 6| secured upon the square spindle 45, whereby rotation of said spindle 45 in either direction will cause the member 6| to engage and operate the finger operating cam 88 to move the arcuate inner ends 54 and 55 of the locking fingers 50 and 5| outwardly, thereby moving the outer ends of said fingers 55 and 5| inwardly to unlocked position.
A locking face plate 62 having opposed locking notches 63 and 64 formed therein, is provided with sloping opposed surfaces 65 and 65, said face plate 62 being secured over a recess 6'! in the edge N5 of the door jam 2, being held in fixed position by means of the screws 68.
' A key hole 69 is formed through the plates 4| and 42 of the lock housing 1, whereby the forked ends 69 of the locking detent 15 which is pivoted upon the pin H and fastened by the spring 12 disposed about pin 1|, will project the hooked end 13 of said detent about a pin 74 disposed transversely of the slot formed in the lower locking finger 5|, for holding the fingers 5|) and 5| in locked position When engaged or seated in the locking notches B3 and 64 in said locking face plate 62 attached to the edge N5 of the door jam 2.
A stop spur 16 will be struck from the side plate 4| and pushed inwardly, serving to limit the rotary movement of the cam actuating member 6| for preventing full rotation of the same. The springs 39 and 40 disposed about the rods or wires 35 and 36 next to the follower heads 3| and 32 will cause the locking fingers 5|] and 5| to which they are attached, to be normally and resiliently moved into locked position.
From the foregoing description, it will be apparent that there has been devised and provided a highly efiicient form of door latch and lock mechanism which will be automatically operated by rotation of the door knobs in either direction, and which may be secured inlocked positionby means of any suitable key placed within;the key hole 69 provided therefor-and brought into engagement with the feet 69" in the-lockingv detent 4 10 which will then be rotated to overlie the pin I4, thus holding said latch and lock mechanism secure.
While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.
