DOOR LOCK Filed July 22, 1930 INVENTOR Huqus'io D "1 ATTORNEYS Patented May 3, 1932 UNITED STATES PATENT OFFIOE A'UG'UfiTO DINA,
SECTOR CORPORATION, OF NEW YORK,
DOOR
Application filed July 22,
This invention relates to a closure fastener, and more particularly to a door lock.
An object of the invention is to provide a lock which is capable of securing the door accurately in a predetermined position.
Another object is to provide a lock which is simple to operate and which positively secures the door against displacement when the same is in closed position.
A further object is to provide a cheap, simple, efficient and convenient device of the type above indicated.
The above objects and others which will be apparent as the nature of the invention is disclosed are accomplished by providing a member carried by the door which is adapted to maize threaded engagement with a stationary stud for securing the door in closed position.
A special means is provided for centering the member with respect to the stud whereby the door is accurately positioned regardless of the condition of the cooperating threads.
The invention is particularly applicable to a metal container in which the doors when closed form a part of the casing and impart rigidity thereto. For example, a container for a portable projection machine of the type disclosed in my copending application Serial No. 132.312. filed March 1, 1930, for ventilating and fire shutter for motion picture projection machines.
It is obvious, however, that the invention maybe used in various other instances where it is desirable to obtain a positive lock for a variable closure member and to secure an accurate alignment of the parts when the member in closed position.
The invention also consists in certain new and original features of construction and combinations of parts hereinafter set forth and claimed.
Although the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, the mode of its operation and the manner of its organization may be better understood by referring to the following description taken in con- N. Y., A CORPORATION OF DELAWARE LOOK 1930. Serial No. 469,668.
nection with the accompanying drawings forming a part thereof, in which Figure 1 is a perspective View of a container showing the locks applied thereto;
Figure 2 is a section taken on the line 2'2 of Figure 1 showing the lock in engaged position;
Figure 3 is a similar section showing the lock disengaged;
Figure 4 is a rear elevation of the lock housing; and
Figure 5 is a perspective of the key used in conjunction with the lock.
Like reference characters denote like parts in the several figures of the drawings.
In the following description and in the claims parts will be identified by specific names for convenience, but they are intended to be as generic in their application to similar parts as the art will permit.
Referring to the drawings more in detail the invention is shown applied to a cabinet having sides 10 and doors or closure members 11 and 12 to which strips 13 and 14 respectively are secured. Said strips are adapted to engage the opposite door when the members are in closed position for securing; the same against displacement. For locking the doors a pair of locks 15 and 16 are provided which are associated with doors 11 and 12 re spectively at a point near strips 13 and 14. Said locks are adapted to engage a stationary portion of side members 10 and to positively hold the doors in predetermined position in a manner to be pointed out.
Each of said locks comprise a member 17 which is journalled in bushing 18 carried in a suitable housing 20 formed in a door 1.1. Said member 17 is provided with a circumferential groove 21 in which a key 22 is seated. Said irev and groove permit a predetermined longitudinal movement of member 17 with respect to bushing 18 and also permit free rotational movement of member 7 7. Bushing 18 may be secured in a hous ng 20 by set screw 23. Member 17 is provided at its outer end with a handle 24 which may have its edge knurled or otherwise formed to provide a gripping surface. The inner end of member 17 is drilled and threaded, as by 013 ELIZABETH, NEW JERSEY, ASSIGNOR T0 INTER-NATIONAL PRO- j threads 25, to receive a cooperating member to be described. Door 11 may be recessed as at 26 to permit handle 24 to normally lie within the plane of said door when the members are in looking position.
The stationary portion of the lock' comprisesa base plate 30 having a pair'of e2 tensions 31 by which it is secured to the housing 32forn1ing a part of side member, 10. Said base platecarries astud 33 which is provided at its end with suitable threads to cooperate with threads 25 of member 17. Said stud is also tapered as at 35 to assist in securing the proper alignment between member 17 and stud 33 when said members are brought into engagement. A stationary sleeve-36 is carried by base member 30 and is provided with a shoulder 37 against which a: cooperating shoulder on a movable sleeve 38 restsfor limiting the movement of said movable sleeve. Sleeve 38 is provided with aninternal taper 39 which cooperates with a corresponding taper 40 formed on the outer surface of member 17 Sleeve 38 is normallyheld in an advanced position by spring 41 which seats in a suitable recess l2 in said sleeve and maintains the cooperating shoulders on sleeves 36 and 38 in contact. A comparatively small amount of'longitudinal movement is permitted in sleeve 38in response to pressure of tapered surfaces 39 and 40 when the lock is brought into engaged position.
It will be noted that when the door is in open position member-17 is loosely carried in bushing 19 and is free to'move longitudinally a distance determined by the key22 and cooperating-slot 21. lVhen the door'is brought into closed position the threads 25 of member 17 contact with'tapered end 35 of stud 33 and are brought thereby into engagement with the threaded end of'said stud. When member 17 isthreaded onto stud 33, as by turning handle 24, tapered surfaces 39 and 40 are brought into engagement and serve to positively align the axes of members 17 and 33. Further turning of'handle 24 compresses spring-A1 and permits thed'oor 11 to be drawn tightly against side 10. In this position the members are held securely-in closed position y means of the cooperating; screw threads on members 17 and 33. Said members are also held against transverse displacement by the cooperating surfaces 39 and 40.
Itwill be noted that the closing of the lock is facilitated by the tapered end 35 on stud 33 which assists in properly aligning the memhers-when the door is closed. Furthermore, after the members arebrought into engage ment the tapered sleeve 38 secures them against transverse movement ant accurately maintains the members in their respective positions. This feature is particularly important in case certain apparatus is carried by the door which must be brought into an exact position with respect to other apparatus carried by the stationary housing or stud members 10. Furthermore, sufficient rigidity is imparted to the housing by the above de scribed lock to materially strengthen the assembly and in the case of the projection machine described in my copending: application above referred to imparts suffici'ent' rigidity to permit transportation from place to place.
l/Vhile certain novel features of the invention. have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device-illustrated and in its operation may be made by those skilled in the art With- 80 out departing from the spirit of the-invention.
