1. THIELEMANN. -Latches for Coach Duurs-.
JNO/139,485. V hmmum@@@1373y` a UO was as ,4M PHaroi/maG/FAPH/c co. mmswmvs's mams) UNITED STATES JOHN THIELEMANN, OF NE WARE, NEW JERSEY.
IMPRQVEMIENT IN LATCHES FOR COACH-DOORS.
Specification forming part of Letters Patent No. 139,485, dated June 3, 1873; application led March 8, 1873. i
To all whom it may concern:
Be it known that I, JOHN THIELEMANN, of Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Coach-Door Locks, of which the following is a specification This invention relates to that class of locks or spring-latches, known as coach-door locks. The object of this invention is to provide a lock or latch that can be opened with great facility from the inside of' the coach, by smply pushing or pulling in one direction the handle of a lever on the inner side of acoachdoor.
In the drawing forming part of this specilication, Figure l shows the interior mechanism ot' lthe lock oi' latch. Fig. 2 is a section of the same on the line x w of Fig. l.
In these figures, B and C are two bent levers jonrnaled upon studs a a2 on the inner side of the lock-plate A. These levers form olle compound lever l'or the purpose ot' withdrawing the lock-bolt or latch E from the mortise in the door-frame of the coach. The arm F of the outside handle, which aotuates the bolt E, throws it back without in any manner actuating the lever O. The levers B and C perform the function of a compound lever only -in retracting the lock-bolt E by moving the handle of the lever G on the inside of the coach, and have no other relation to each other for any other purpose.
A convenient method of securing the bolt E to the lock-plate A is shown in the drawing, but which method, briefly described in the next paragraph, is not claimed as forming any `part of this invention. A spring of any ordinary construction presses against the heel of the bolt E, which bolt by means ofthe pin i therein near its heel, is guided by a slot in the lock-plate A in which the pin i slides; this pin issecuredin the slotbya nuton itsend.
The pressure of this spring upon the bolt E causes it to spring into the mortis@` of the dor-frame whenever the door is closed.
One great advantage or" llns lock or latch is its great simplicity. The combination of the levers B and C, forming one compound lever, and the position ofthe lever C, wherebyl it can be made without inconvenience ot' cony the bolt E without strain or pain upon the f hand or fingers; the absence of such leverage in locks heretofore made frequently causes .not only such pain, but otten a total failure to open the lock in sudden emergency.
As my invention, I claim- In a coach-door lock or latch, the bentlevers B and G,journaled upon separate pins a a2, and forming, by the` contact of their short arms, one compound lever, in combination y with the lock-bolt E, whereby the said bolt E is retracted in the manner substantially as described, for the purposes set forth.
