JOHN ELLIS, OF DETROIT, MICHIGAN.
Speccaton of Letters Patent N0. 32,990, dated August 6, 1861.
To all whom it may concern:
Be it knoivn that l, JOHN ELUS, ot' Detroit, in the county ot layne and State et' lvl'ichigan, have invented certain new and useful .iniprovemente` in Gate-Latches; and do hereby declare that the following is a full and complete description of the construction. and operation ot the same, reference being had to the accon'ipanying drawings, making a part of this specification, in ivhich- Figure 1, is a perepectivc view ot the catch entire. Fig. l, is a side view. Figs. 3, and Ji, are front views et the caee, with the cap removed. Fig. 5, is a perspective View et the case, and cap, detached trom each other. Fig. (i, is; a view et the latch.
rll`he same lettere refer to like parts, in the different figures.
My improvement relates, to a catch and latch, so constructed, that the gate can be opened and closed either way, and will tasten itself, at once, and not pass through, and Saving back and forth.
ln the figur-ee A, represente, the back part et the case, that is designed to be Secured to the post, by Screws paseing through the holeS (fr, Seen in Figs. 3, Ll and l, and B, are projections, forming a part ot the case, and that Support the tumbler C, as Shown in Figs. 3, t, and 5, and D, represents the catch, with curved lips or planes D, connected to the lower end of the cri-Se, and forming a part of it.
When the gate is Shut, or open, the tumbler C, resting on the pieces B, B, is vertical, in the position indicated by the dotted linea in Fig. 3, and if the gate is latched, as
indicated, by raising the latch H, the tinnbler C, iS elevated, and the gate can be opened as well one Way as the other, tor the curved planes ly, are alike, and the tumbler C, being in the center, the latch it, can pass ont either ivay alike. But it' the gate open and Swings shut, the latch H, slides up over the curved plane D, coming in contact With the tumbler, and forcing` it along, until H, falls into the catch D, when the tumbler returns to its 'former place.
rThe gate cannot swing through, when lehutting'either Way, however great its niomentuln, for the pieces l, B, preventthe tumbler, trom swinging out ot the way, any ilurther than shown, and indicated by the dotted lines C, in Fig. it, in Which, it will readily be seen, that the space is not near Wide enough for the latch to pass through, and it Will ot course tall down into the catch D.
F, represents the cap or cover, that is placed over the upper part of the case and tumbler. It. is represented detached in Fig. 5, and is secured to the post by Scre passing through the holes Y), 7), when in use.
Fig. (i, is a perspective view ot the latch il. that is connected to the gate.
1What l claim aS my improvement and deeire to secure by Letters Patent is:
The tumbler C, in combination with the latch and catch, when operating conjointly, `eufstantially, aS Het. forth, for the purpose described.
