APPLICATION FILED AUG.2I, 1918.
Patented July 59 MIZ@ ERNEST EKSTROM, OF ROSHOLI, SOUTH DAKOTA.
LATCH.
Specification of Letters Eatent.
Patented J uly, 1920.
Application filed August 21, 1918. ySerial No. 250,801.
To all whom 'it may concern:
Be it known that l, llnNns'r S. EKsTRoM, a citizen of the United States, residing at Rosholt, in the county ot Roberts and State of South Dakota, have invented certain new and useful Improvements in Latches, of which the iollowin, .fV is a specification.
ri'his invention relates to improvements in door latches and one object is to provide a simple practical device of this class that is cheap to manufacture and eilicient in operation. With the foregoing and other objects in view the invention consists in the com-` bination and arrangement of parte to be hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawing which forms a part of this specilication and in which- Figure l is a plan view or' the latch.
Fig. 2 is a cross section taken on line 4-4 of Fig. 1.
Like reference characters denote corresponding` parts throughout the several views.
The reference numeral l denotes a door provided in the wall 2. l provide a bracket 3 secured to the wall 2 and to said bracket the liasp 4l is secured by the hinge 5, 'the hafsp being formed with the usual perforation 6.
l provide a spring; la upon the hinge pintle which spring` yieldingly forces the hasp 4 inwardly or toi rard the wall 2. The angle piece 7 is 'formed with a pair of ears l5 which are connected by the pin 1G upon which the curved bolt 17 is lulcrumech the short end of said bolt forming a heel 18 and the longer end of Said bolt being adapted for disposal in the perforation 8 of the angle piece 7. To unfasten the door the free end of the hasp l is moved outwardly and door can now be opened. To tasten the door again, it is closed, and the hasp simply moved into engagement with the angle piece 7. This movement of the hasp causes it to engage with the heel 18 of the bolt 17 and right the bolt or move it again into the position shown in full lines, Fig. 2, thus engaging it again with the perforated end of the said angle piece. The necessity of direct manual movement of the bolt is obviated in this form of latch as the bolt movement is controlled automatically by the hasp movement.
-What is claimed is n a latch, an angle piece having one end secured toa support and its free end perforated, ears formed u pon the non-perforated end of said angle piece, a bolt iiulcrumed to said ears and having; a long` and a short end, the long` end of said bolt being adapted for engagement with the perforated end et said angle piece, and a swinging hasp adapted for releasable engagement with the free end of said angle piece, said hasp en gagging; with the long end off said bolt while movingn in one direction and engaging` with the short end oit said bolt while moving` in the opposite direction.
In testimony that l claim the 'foregoingas' my own l have hereto ailiXed my signature 1n the presence of two subscribing` witnesses.
