IMPROVEMENT IN REVERSIBLE KNOB-LATCHES.
Specification forming part of Letters Patent N0. 186,556, dated January 23, 1877; application tiled January 5, 1877.
` To all whom it 'may concern Be it known that we, WILLIAM-M. GRIS- coM and FRANCIS GRossMAN, of Reading, Pennsylvania, have invented certain Improvements in Reversible Latch-Locks, of which the following is a specification:
The object of our invention is to so construct a reversible latch-lock that the latch can only be reversed in the absence of the knob-spindle from the hub; and this object we attain in the manner which we will now proceed todescribe, reference being had to the accompanying drawing, in which- Figure l is a front view of the lock, partly in section, and with the face-plate removed; Fig. 2, a view of a portion of the same with the parts in a diiierent position; and Fig. 3, a
` sectional plan on the line l 2, Fig. 1.
A is the casing of the lock, in the lower portion of which are arranged the parts for operating the locking-bolt B; but as these parts are similar in construction and operation to those usuall5r employed in locks of this class, description of them here will be unnecessary. D is the latch-bolt, the spindle a y `of which is swiveled at the inner end to a yoke, E, which embraces the hub F on the knob-spindle b, and has lugs d d, on which usually act the arms e e on the hub, in order to retract the latch-bolt. In the present iustance, however, only oneoi1 the arms e is securedto the hub, the other forming part of a lever, I, adapted to a slot cut in the hub F,
and pivoted, by means of a pin, i, to lugs m m on the same. In order to cheapen the lock this pin t is not riveted, being retained in place by the opposite face-plates of the lock.
` The body of the lever I is cut away, so that when thelever is in the position shown in Fig.
l it will not interfere with the continuity of the square opening in the hub for the receptionof the knob-spindle, this cutting away of the lever forming on the same a finger, s. Against a lug, t, on the short arm of the lever, bears one end of a bent spring, J, the opposite end of which is hooked around a shoulder, .z', on the hub, so that` the risk of accidental displacement of the spring is prevented. The tendency of the spring J is to maintain the parts in the position shown `in Fig. 1, so that the knob-spindle can be readily inserted into the opening in the hub. I
When the parts are in the position shown in Fig. l-that is, with the knob-spindle in position, and the latch-bolt in the recess in the edge plate of the lock-any attempt to draw the Said latch-bolt forward, so as to free dle is not in place the withdrawal of the latchbolt will not be interfered with.
We have shown our invention as applied-to a latch-bolt having an independent. spring, y, for resisting the thrust against the outer end of the bolt; but it will be evident that it can be applied to latch-bolts of a different construction with equal facility.
We claim as our inventionl. The combination, in a reversible latchlock, of the yoke E and its lugs d with the slotted hub F, its arm e, and pivoted lever I, as set forth.
2. The combination of the slotted hub F and its pivoted lever I, having a finger, s, with a spring, J, as described.
3. The combination of the slotted hub F and its pivoted lever I with the bent spring J, bearing at one end against the lug t on the lever, and hooked at the other end, for adaptation to a shoulder, m, on the hub, as set forth. i
In testimony whereof we have signed our names to this specification in the two subscribing witnesses.
WILLIAM M. GRISGOM. FRANCIS GROSSMAN. VWitnesses:
HARRY SMITH, S. D. DYER.
