' "SPRING-LOCK. I

Qlorallwhom it may-coniccm:

Be it known that 1, PETER FF. AUonN- 1 emu-N, of Stamford, :in the county of Fairfield and State of' Connecticut, have invented certain new and useful Improvements in Spring-Locks; and =I do hereby declare the following to'be a'full, clear, and exact de- .scriptionof the invention, such as will enable others skilled in the art to which it aplpfrtains to make and use the same. I

y invention relates to an improvement in spring locks, the object being-to provide -:a lock with thebolt actuating member normally resting within a recess 'in the face plate of the lock, so that it may be secured to a floor-board or box, Without having any members projecting to any great'extent beyond its face plate.

A further object is'to provide a spring lock of the character above described with Fig. 3 is a view in side elevation, and Fig.

4 is a view in end elevation of the same.

, 1 represents a face plate or casing adapted to be let into a floor-board, box, or other object where a projecting part would be objectionable, and 2 is an end flange, the plate and flange having suitable screw holes for the passage of securing screws. This plate 1 carries a lock 3, preferably. of the pin tumbler type as shown, the plug 4 of which actuates a cam 5 which latter, in the present instance, is mounted to turn on the a plug and is actuated by the cam 6 rigidly secured to' the plug, the said cam engaging the pins 7 pro ect-ing from the outer face of cam 5, whereby the cam 5 may be turned by the rotation of the cam 6 in either direction. Pin 7 forms a stop for limiting the movement of cam 5.

Mounted in the flange 2 of the face plate, is the bolt 8, provided at its inner end with a stem. 9, which passes through the bearing 10 secured to or integral with the inner face of plate 1, and embracing the stem 9, is the Specification of Letters Patent.

Application filed February )9, 1912. Serial No; 676,660.

Patented Aug. 6,1912.

1 spring '11, which i-latter tends .to normally hold the'bolt'8 in itsrprojected position as shown.

The bolt is recessed in its ".front 'face to form the shoulder .12, 'agai twvhichithe inwardly projecting end :13 o the labohnctuatmgmemberior lever 1 4bears. 'This member 14 is pivoted at 15 to t-heifaoe plate-and normally=rests within. arecessed'seatlformed inthe front face of the plate 1,-so as'to-be flush'with'the outer surface of-saidplate 'as shown in Figs. 1 and 3. It is preferably made ring shape as-shown so astobe convenlently grasped and actuated, and the portion of the face plate immediately'below the open center of'the 'boltactuating-memher 14 is depressed asat '16 whereby theends of the fingers may engage'the ring shaped member from below or a at its inner slde, when it is desiredto actuate-the bolt.

It will be evident from the construction as illustrated 'that lay-grasping andpulling outwardly 'on the bolt actuating member 14, so -as-to turn same from its positionflush with the face plate, up to an angle of about ninety degrees or less to said face plate, that the inwardly projecting end 13 of the bolt actuating member, bearing against the shoulder 12 on the bolt acts as a cam and forces the bolt inwardly to release it from its keeper. Thls movement of the bolt puts spring 11 under compression, hence as soon as the actuating member 14 is released, the spring forces the bolt outwardly and the shoulder 12 hearing against the bent end of actuating member, turns the same down into its recessed seat in the face plate, and holds it there a ainst accidental movement. Cam 5 is located in the plane of the stem 9 of the bolt, and when turned, as in Fig. 2, to bear against said stem, it deadlocks the latter against movement and also looks the bolt actuating member 14 against outward movement. By turning the cam 5 one hundred and "eighty degrees or less so as to carry its cam face away from the stem 9, sufiicient room is provided for the full throw of the bolt, by the actuating member 14. With this improvement the spring bolt is normally in its locking position and is retracted by moving the bolt actuatin member outwardly from its position flus with the face late, and as soon as said member is release the spring 11 acting against the bolt throws the latter to its projected position and also turns the bolt actuating mem ber back into its recess in the face plate. By actuating the lock 4, cam 5 will be turned to a -position to deadlock. the bolt, and obviously when the bolt is dogged by the cam, the bolt actuating member will also be held against'movement from its flush position in the face plate.

It is evident that changes in the construction and relative arrangements of the several arts might be made without avoiding my invention and hence I would have it understood that I do not'restrict myself to the particular construction and arrangement of parts shown and described, but,

Havin fully described my' invention what I cfilim as new and desire to secure by .Letters-Patent, is: Y

1. In aspring lock, the-combination of a face plate or casing having a recessed outer face, a bolt provided with an-outwardly projecting shoulder, a spring normally tending to hold the bolt projected, and a bolt actuat ing member pivoted to the face plate or casing, normally resting in said recess, and provided with an inwardly projecting part vlocated in front of, and adapted to engage the outwardly projecting shoulder on the bolt.

2. In a spring lock, the combination of a ing witnesses.

face plate or casing having a recessed outer face, a bolt provided with anout-wardly proj ecting shoulder, a spring normally tend ing to hold the bolt projected, a bolt actuating member pivoted to the face plate or casing,'normally resting in said recess and provided with an inwardly projecting part located in front of and adapted to engage'the outwardly projecting shoulder on the bolt, and a key-lock for deadlocking said bolt.

3. The combination of a face plate or casing, a bolt, a spring normally tending to hold the bolt projected, a bolt actuating member pivoted to the face plate of thecasing, and provided with a part engaging the bolt whereby when said actuating member is moved outwardly from the face plate the bolt will be retracted, a camlocated in the plane of the rear end of the bolt and adapted to be turned to engage said bolt, and a key lock for actuating the cam to lock and release the bolt.

In testimony whereof, I have signed this 7 specification in the presence of two subscrib- PETER AUGENBRAUN'.
