HARRY J. PERKINS, OF GRAND RAPIDS, MICHIGAN.
OPEN-DOOR LOCK.
SPECIFICATION formingpart of Letters Patent No. 662,300, dated November 20, 1900.
Application filed May 28, 1900.
To all whom, it may concern:
3e itknown that I,I-IARRY J. PERKINS,a citizen of the United States, residing at Grand Michigan, have'invented new and useful Im' provements in Open-Door Locks, of which the following is a specification.
This invention relates to a new and useful open-doorlock; and the invention consists in the construction and combination of parts hereinafter described and claimed; and the objects of my invention are, first, to construct a safety-lock which will allow the door to be opened for a few inches to converse with a person standing on the outside of the door and yet preventingress; second, to furnish a lock which will show at a glance whether the door is locked or unlocked; third, to furnish a lock which will lock the door securely when opened a few inches and prevent the door frombeing opened or shut; fourth, to furnish ventilation and yet keep the door securely locked. These objects I accomplish by means nying drawings, in which Figure 1 shows an inside perspective view of a door opened and locked open by my device. Fig. 2 shows a plan view of my device attached to a closed door. Fig. 3 shows a plan view of the device as it appears when attached to the door opened until the hinged arm is held against the lug F, as hereinafter described. Fig. 4: shows the inside of the door with the bolt unlocked and hanging beside the door-frame. Fig. 5 shows an elevation of the device from the inside of the door, the bolt being in looking position, the dotted lines showing the bolt raised out of locking position. Fig. 6 shows an end perpective view of the device in looking position, the bolt A being in section. Fig. 7 is a side elevation of the staple and plate to which the locking-bolt is attached, showing my preferred form of staple. Fig. 8 shows a side elevation of the staple with an end view of the locking-bolt, with the looped attaching part bent for the purpose of automatically turning the bolt, as hereinafter described. Fig. 9 shows the reverse side of the staple and plate with a sectional view of the attachingbolt through its flattened portion. Fig. 10 showsa side elevation of the slotted arm with Serial No. 18,315. (No model.)
a sectional view of the bolt, showing its position in the arm when the door is closed. Fig. 11 shows a side elevation of a portion of the attaching-bolt with a section of the bufferin place. Fig. 12 shows also a side elevation of the attaching-bolt with the buffer in position.
Similarletters refer to similar parts through out the several views.
A is a locking-bolt formed, preferably, in the form shown in Fig. 1.
B is a plate secured to the door-frame by screws or other suitable means.
D is a metal staple secured, preferably, to the plate B, but may, if desired, be secured directly to the door-frame. The bolt A is bent at J, so as to form an eye engaging with the staple D, as shown. The locking-bolt is flattened, as shown by E, in order to allow the same to engage with the hinged arm hereinafter described.
0 is a metal plate secured to the door by screws or other suitable means.
H is a slotted arm hinged at I to the plate 0. The slot is preferably at the top, as shown by K. This slot K opens into a circular part adapted to receive the cylindrical part of the locking-bolt. I
G is a head or enlarged end of the lockingbolt.
F is alug upon the locking-bolt. The con nection of the locking-bolt to the staple D is such that the bolt may be partially rotated in order to make the engagement of the bolt with the hinged arm H, and also so as to pass the lug F through the slot K in order to lock the door open. When the door is closed, the locking-bolt hangs beside the door-frame, as
shown in Fig. 4;. The door being closed, the
bolt is raised to the position shown by dotted lines in Fig. 5 and turned so that it will pass into the hinged arm H, and the bolt rests therein, as shown by solid lines in said Fig. 5. If the door he now opened, the hinged arm slides along the bolt until it is stopped by the contact of the lug F with the arm, and the door is locked from opening any farther. If
the door is to be locked open, the bolt A is turned so that the lug F will pass through the slot K, and the further movement of the slotted arm will be stopped by the head G of the bolt A. The bolt A is then turned so as to bring the lug into position, as shown in Fig. 1, and the door is both locked open and locked from opening any farther. The bolt A is so hung in the staple D that it will not turn of its own accord when the door is shut, but will retain its locking position and can be turned only so as to unlock the door by a person on the inside of the house and when the door is closed.
In the forms shown in Figs. 7, 8, and 9 I provide an upward loop or curve, (shown by P,) which engages with the lower end of the loop J and is adapted to hold the lockingbolt in the position shown by E in Fig. 1 when thedoor is closed.
Q shows the buffer, made of india-rubber or any other suitable material, which is fitted into the groove R in the head of the lockingbolt and serves to prevent the bolt from bruising or injuring the door or door-casing.
When the door is opened,as above described, the bolt cannot be removed from the slotted arm, and when closed with the construction last above described the curved form of the loop J automatically turns the bolt slightly, so that the flattened portion of the bolt lies in the arm in the position shown in Fig. 10. The object of this construction is to prevent the possibility of lifting the bolt from the arm by any means from the outside of the door.
Having thus described my invention, what I claim to haveinven ted, and desire to secure by Letters Patent, is
1. A device of the character described, comprising a sliding, partially-rotatable bolt having a headed free end and a lug relatively arranged with said headed end and a pivoted arm having a slotted aperture to receive said bolt and to permit the lug thereon to pass therethrough and effect with said headed free end of said bolt, the interlocking of said arm and bolt, consequently the retention of the bolt against sliding or endwise movement, substantially as set forth.
2. Adevice of the character described, comprisingasliding, partially-rotatable bolt hav-.
ing a'fiattened portion, a headed free end,
. and a lug relatively arranged with said headed free end, and a pivoted arm having a slotted flattened portion of the bolt providing for the ready separation of the parts, as required in closing and securingthe door in the usual way, substantially as specified.
3. A device of the character described, comprising a staple or keeper fixed to the doorcasing, a bolt loosely connected to said staple or keeper and having a flattened portion, a headed free end, and a lug or stop arranged a short distance from said headed free end, and an arm pivoted to the door and havinga slotted aperture, adapted to receive said bolt, and provided for the sliding of said bolt and its retention at a certain point therein, substantially as set forth.
4. The combination Witha door-casingand door, of a locking-bolt having one end formed with a curved loop, said bolt further provided with a contracted portion near said curved loop, a staple D formed with a curved por tion and adapted to receive said loop, and a hinged arm provided with a cylindrical opening terminating in a suitable slot adapted to permit of the entrance of said bolt to said opening. I
5. In a device of the character described, the combination of a hinged or pivoted arm applied to the door, a partially-rotatable bolt havinga stop and adapted to slide in said hinged arm to permit the engagement therewith of said stop, and a staple fixed to the jamb or casing and connected to said bolt and having an upward-curved loop for engagement with the eye-ended or looped portion of said bolt, substantially as set forth.
6. In a device of the character described, the combination of the partially rotatable bolt having a cross-sectional flattened portion and a stop and flexibly connected to the jamb or casing, and a pivoted or hinged arm applied to the door and having a slotted opening to receive and permit the sliding thereon of said bolt, substantially as set forth.
7. In a device of the character described, the combination of a hinged or pivoted arm applied to the door, and a partially-rotatable bolt having a stop at its free end and adapted to slide in said pivoted arm to provide for the engagement therewith of said stop, a second stop or lug on said bolt removed from the free end of the bolt and adapted to prevent the door from shutting when open to the eX- tent of said bolt, and-a staple applied to the jamb or casing and'having connected thereto said bolt, substantially as set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
