JOHN B. WADE, O13 ANIMAS, NEW MEXICO.
DOOR-LOCK.
To all whom it may concern:
Be it known that 1, JOHN B. WVADE, a citizen of the United States, residing at Animas, in the county of Grant and State of New Mexico, have ipvented new and useful Improvements in Door-Locks, of which the following is a specification.
The invention relates to a door lock, and
' has for its primary object to provide a lock of a character wherein, on the unlatching of the door and the swinging thereof to open position, the same can be held in such open position or at any angle relative to the door frame.
Another object of the invention is the provision of a lock of this character wherein the same can be associated with the ordinary door lock and is adapted particularly for holding the door in adjusted position on the opening thereof, the lock being of novel formation and construction and preventing the slamming of the door or the closing thereof when remaining open.
A further object of this invention is the provision of a lock of this character which is extremely simple in construction, thoroughly reliable and efficient in operation, strong, durable and inexpensive of manufacture.
Other objects will be in part obvious and in part hereinafter pointed out.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims hereunto appended.
In the accompanying drawings: Figure 1 is an elevation of a door frame and door showing the lock constructed in accordance with the invention applied, the door being closed; Fig. 2 is a top plan view showing the door in open position; Fig. 3 is a fragmentary vertical longitudinal sectional view through the look; Fig. 1 is a fragmentary plan view of the locking bolt. Fig. 5 is a perspective view of the knob spindle arm.
Similar reference characters indicate corresponding parts in the several views of the drawing.
Referring to the drawings in detail, A designates a door frame having its head B extended at one end beyond the door frame, while swingingly connected to the latter is the usual door C carrying a lock or latch D,
Specification of Letters Patent. Patented Aug, 15, 1916.
Application filed November 30, 1915.
Serial No. 64,336.
the pintle E of which has mounted thereon an arm 10 which has connection with the lock for holding the door in adjusted open position, hereinafter fully described.
Upon the head B of the door frame A is mounted a segment 11 formed in its lower edge with spaced notches 12 providing therebetween rack teeth 13, while fixed to the door C is a lock housing 14 having arranged therein a sliding bolt 15 which is adapted to engage in any one of the notches 12 in the segment 11 for holding the door when opened in adjusted position at an angle to the door frame. The bolt 15 is formed with a reduced end 16 which extends without the housing 1a and terminates in an eye 17 in which is connected the upper hook end 18 of a rod 19, the opposite hook end 20 of which is engaged in the free end of the lever 10 so that on the turning of the pintleE in one direction the rod 19 will pull upon the sllding bolt 15 to retract the same within the housing 14:, and on the turning of the pintle E in this direction the door will be unlatched for the opening thereof, the pintle E being provided with the usual hand knob 21 to permit the turning thereof.
Surrounding the reduced end 16 of the sliding bolt 15 is a coiled expansion spring 22 which serves to act upon the bolt for throwing the same into locking engagement in any of the notches 12 in the rail 11 for the locking of the door C in open position at any angle relative to the door frame.
Mounted to straddle the rail 11 is a loop or yoke 23 which is fixed to the uppermost end of the housing 14;, and this yoke or loop follows the rail during the opening movement of the door C.
Mounted on the housing is a pivoted arm 24 formed with a lug 25 projected inwardly through a slot 26 in the said housing to engage in a U-shaped slot 27 formed in the sliding bolt 15 so that the bolt can be locked in extended or retracted position on the swinging of the arm 24: upon its pivot. The.
arm 2%, when swung to the right, permits the lug 25 to engage the perpendicular portion of the slot 26, and on the swinging of the arm to the left the lug enters either of the horizontal stretches of the slot for the looking of the said bolt in extended or retracted positions. When the bolt is extended it will engage in any of the notches 12 on opposite sides of the teeth 14 on the rail 11 and thereby hold the door in locked open positeriorly to the housing for swinging movement, a pin mounted 1n the arm and passed through the housing for engagement in the 1 slot in the bolt to traverse the same for looking the said bolt in extended or retracted positions.
In testimony whereof I atlix my signature in presence of tWo Witnesses.
