UNITED STATES PATENT OFFICE.
THOMAS s. LIVERMORE, 0F LEICESTER, MASSACHUSETTS.
LATCH.
SPECIFICATION formingpart of Letters Patent No. 225,707, dated March 23, 1880.
. Application filed January 24, 1880.
To all whom it may concern Be itknown that I, THOMAS S. LIVERMORE, of the town of Leicester. in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Door-Knob Latches 5 and Ido hereby declare that the following is a full and clear description of the same, reference being had to the accompanying drawings, which form a part of this specification.
The object of this invention is to furnish a device by which the latch can be moved so as to open the door by pushing the knob in 011 one side of the door or by pulling it on the opposite side, and not interfere with the method for turning the knob and spindle to open the latch as in the ordinary way; and it consists in having a thin triangular piece of metal, having a collar attached to one corner of the broad end and placed on the spindle loosely next beneath the end of the socket of one of the knobs. The point of the triangular piece is inserted through a slot in the casing of the latch and operated in a slot in the latch-bolt, or it may be made to operate against a pin in the bolt, as may be most convenient.
In'the drawings, Figure 1 represents a perspectlve view of the door knobs and latch inserted in a frame. Fig. 2 represents the latchbolt, the spindle, and my triangular piece 011 Fig. 3 represents a side view of the parts, namely, the latch-casing, the bolt, and spring, and end of the spindle with the collar of the triangular piece thereon.
A A in Fig. 1 denotes the door-frame, in which the latch E and easing B are inserted. O and D denote two knobs, and J and J their sockets, in which the ends of the spindle G are inserted and fastened.
F in Fig. 2 denotes my triangular piece, with its collar F around the spindle G. H denotes a slot in the latchbolt E, in which the triangular piece is operated by pushing on the knob on one side of the door and by pulling on the other side,
L L denote two arms of the latch-bolt, supported in the casing, with their ends L turned so that the cam K, which is on the spindle, will engage therein when turned in the ordinary way by the knob aud spindle. The collar F, being loosely on the spindle G, is not affected by turning the spindle to open and close the latch with cam K. The point of the triangular piece is inserted in the slot and the collar against the end of the socket J, so that when pressure is applied to knob O the triangular piece is pushed into the slot of the latchbolt, which unlatches the bolt the same as if it were unlatched by turning the knob, and by pulling knob D the effect is the same.
The spindle should be lengthened about half an inch, so as to allow for the operating of the triangular piece.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In combination with the knobs O and D and the socket J, Spindle Gr, cam K, latch-bolt E, the triangular piece F, having collar F around the spindle G, and operated in the slot H, substantially as and for the purpose herein shown and described.
THOMAS S. LIVERMOBE.
