WALLACE T. MNGER, OF NEW BRITAIN, GONNEGTICUT, ASSIGNOR TO I. & F. OORBIN, OF SAME PLACE.
Letters Patent No. 113,909, dated April 1s, 1871.
The Schedule referred to in these Letters Patent and making part of the lama.
To all whom 'it may concern 4 Be it known that I, WALLACE T. MUNGEB, of
'New Britain, inthe county of Hartford and State of Connecticut, have invented and made a certain new and useful Improvement iuLocks; and the following ishereby declared to be a full and correct description thereof.
My invention relates to that class of locks or latches in which the latch is operated by the knob, and is capable of being reversed to change it to a right or lefthand lock. p
I make use of a swinging arm moving upon a pin 0r stud on the saddle-plate of the lock or latch, and provided with a projection upon its outer cud to take against the head upon the inner cud of the latch-shank, and thereby keep said latch in its proper position relatively to the saddle-plate so that the two will move together when the knob is turned, or, when said arm yis raised so that the projection is clear of the latchhead, allow the latch to` m'ove forward sniiciently out of the lock-case so that it can b e reversed to change the inclination of the head of the latch and make it a Vright or left-hand lock or latch.
I provide a spring to keep the swinging arm in its correct position, and so support the latch-bolt that it will always be kept in its correct horizontal position.
In the drawing- Figure 1 is an elevation of a lock with my improvement applied thereto, the cap-plate being removed and the parts in their normal position; l
Figure 2 is t similar view, with the parts in position to allow di' the latch being reversed; and
Figure 3 is an elevation of the cap-plate of the lock a represents the case ofthe look;
b, the bolt; andV c, the tumbler, to be operated by a key of any de sred character. l
The latch-holt is also of usual character, and is formed 'with the beveled head (l, cylindrical part e, shank f, and head g, and is provided with the spring h by which it is projected, said sp1-ing acting between. the cylindrical part c and the plate e'.
tis the hub for the knob-spindle, and said hub is formed with the cams It It toact against the studs Z Z/ l upon the saddle-plate m, and move said saddle-plate and latch when the knob and spindle are turned.
o is the swinging arm, pivoted at p upon the saddleplate m, and formed with the projecting stop q to take against the head y of the latch-,bolt and keep said said plate fm and latch-bolt, when iu the position shown in iig. 1, will move together.
ais a spring to keep the arm o in its proper position; and at n I provide a projecting toe upon the saddle-plate m for the head g to rest upon, so that the spring rand arm o cannot move the latch-bolt from its correct horizontal position, and th'us prevent or against the stops t.
In the cap-plate u I provide au opening, fo, to allow for the arm o vbeing raised to disconnect the stop q from the head g, so-that the latch-bolt can be projected' by its spring hto the position shown in fig; 2 to change orireverse the latch-bolt and make -it a right or l'efthand latch; and I make the stopy q as a double incline, and also form the upper part of the head g as an incline, so that the simple act of forcing in the latch-bolt, after being changed or set as desired, raises the arm o and allows the parts to resume the position shown in lig. l.
ont of the lock whenthe same is being reversed, Vand become a guide for directing the head g'back into place between the arm o and projection n.
I claim as my. invention- The reversible latch with the shank f passing between the stops t and carrying the swivel-head g, in combination with the arm o and projection n on ,the plate an, the parts being constructed and arranged substantially as specified. p l Signed by me this 18th day of February, A. D. 1871.
IV. T. MUN GER.
Witnesses CHARLES Puck, EDWD. L. PRIOR.
head g within its recess in the saddle-plate m,'so that friction of the shank f in sliding through the plate efrr.Ihe head-g and stops t prevent the latch being taken
