LATCH.
Specification 01; Letters Patent.
Patented Aug. 2, 1921.
Application filed November 22, 1920. Serial No. 425,687.
To all whom it may concern:
Be it known that I, CLARENCE R. BUM- BARGER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Latches; and I do declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to lettersand figures of reference marked thereon, which form a part of this specification. V
This invention relates to door latches and particularly to a hand operated means for effecting the operation of a closure latching means in a convenient manner.
'Means is provided whereby the latch may be readily attached to a door as, for example, a steam room, ice box, shutter, or other suitable means, there being provision made to adjust the bolt with respect to its keeper so that the door or other means to which the latch is secured may effect a'tight closure for the opening which it is to close.
The novel arrangement of parts and combinations of parts will be apparent by reference to the accompanying drawlngs, in which Figure 1 is a cross sectional View through a door to which my invention is applied, and
Fig. 2 is a perspective view of the latch detached. 7
Referring now tothe drawings by numerals of reference:
1 designates a door provided with an opening 2, receiving a socket member 2 hav ng a through opening 4' laterally elongated with parallel walls 5 and .6, inclined at an angle to the axis of the opening. The socket memher is provided with a'flange 7 having a spring seat 8 at one edge thereof, the opposite end of the socket member being cov- Y ered by a cover plate 9 through which and the flange 7 may pass bolts or fastening devices 10 to secure the socket and face plate'in clamping relation to the door.
Pivoted within the through opening of the socket member is an arm 11 of an elbow le- 'wardly to compress the spring 20, one end of which is seated upon the seat 8 and the other upon the seat 21, the latter carried by the sleeve 14.
The long arm 22 of the elbow lever is connected by the forked or bifurcated portion 23 of an elbow-shaped link 24 to a socket member 25. The socket member may be fastened to the door by a suitable fastening device or bolts 26. The link 24 is pivoted to the socket member, as at 27, and to the long arm 22 of the elbow lever, as at 28.
When the parts are in the position shown in Fig. 1 and it is desired to open the door, the operator pulls on the bar or long arm 22 until it is moved to substantially the relatve position shown in dotted lines in Fig. 1. This swings the link 24 to its limit and consequently, limits the swinging movement of the bar 22. At the same time it moves the bolt or bill 15 off the shoulder 16, allowing the door to be opened in the direction of the pull.
VVhen'it is desired to latch the door, it may be closed, and the inclined edge 29 of the bill or bolt 15 will ride on the inclined 'edge 30 of the keeper until the bill or bolt passes over the edge of the shoulder 16, when the parts will again assume the position shown in full lines in Fig. 1.
It 1s obvious, of course, that the compression of the expansion spring will tend to hold the parts'in the position shown in Fig. 1 at all times.
If the door is to be opened from the inside, the operator may push on the free end of the handle 19,- compressing the spring sufficiently to movethe bolt or bill away from the keeper. Ordinarily, however, the door is operated from the outside; that is, the side on which is arranged the long arm 22, the
. move the loosened and the "handle of the sleeve and bill 15 may be given one or more complete turns to reduce the distance between the members 15 andl6. If they do not overlap, a reverse operation can take place and when the bill is tightened.
In the description I have referred to the operating means as an elbow lever consisting of a short arm 11 and a long arm 22; in effeet, the members 11 and 22 constitute an elbow lever although the arm 22 has a slight pivotal movement with respect to the arm 11 to provide for short clearances 1n operation. For example, if the arm 22 was actually rigid with arm 11, it would have to swing out a considerable distance from the door, butby pivoting it thereto the clearances will be considerable less than if rigid.
It will be seen from the foregoing that the device is easily applied and easy to operate.
What I claim and desire to secure by Let ters-Patent is:
1. A latch comprising a pivoted elbow lever, one arm of which is an operating arm, and a latch boltsupported by and at right angles to the other arm and parallel withthe operating arm.
2. A latch comprising an elbow lever having a short arm and a long arm, a door-engagingmember, a link connecting the doorengaging memberto the free end of the long arm, and a latch bolt carried by the free end of the short arm.
3. A latch comprising an elbow lever having a short arm and a long arm, a door-engaging member, a link connecting the doorengaging member to the free end of the long arm, and an adjustable latch bolt carried by the free end of the short arm.
4. A latch comprising an elbow lever having a short arm and a long arm, a door-engaging member, a link connecting the doorengaging' member to the free end of the long arm, an adjustablelatch bolt carried by the free end of the short arm, and a spring for swinging the elbow lever on its pivot to I latch bolt into keeper-engaging position. Y
5. A latch comprising a pivoted elbow lever having a short arm and a long arm, an
adjustable latch bolt-on the short arm of the elbow. lever, a spring seat, a spring interposed between the spring seat and the properly set, the set screw can be tube being elliptical in cross section, means for securing the face plate tojthe flange of the socket member, an elbow lever comprising a short arm and a long arm, means for "pivoting the short arm within the tube of the socket member, threads on the end" of the short arm, an adjustable latch bolt having internal threadsto engage those on the free end of the short, arm, a spring seat on the socket member, and a spring interposed between the socket member and the bolt, the long arm constituting a handle whereby the latch may be operate 1 7. A latch comprising a socket member consisting of two members, one of which is a flanged tube and the other a face plate, the
