HMPROVEMENT IN REVERSIBLE KNOB-LATCHES.

Specification forming part of Letters Patent No. 137,655, dated April 8, 1873,' application filed March 2l, 1873. Y l

To all whom it may concern:

Beit known that I, CHARLES S. J ENNINGs, of Meriden, in the county of New Haven and State of Connecticut, have invented a new made reversible for a right or left hand door by partially withdrawing the bolt from the case, and particularly to that class in which the bolt and its whole mechanismthat is, the yoke and follower--are drawn forward with the bolt. The object of this invention is tO so hold the follower that it may be always retained in the same relative position to the yoke, and to insure the drawing back of the follower, yoke, and bolt into place after they have been withdrawn; and the invention consists in constructing the'follower with a hook upon its rear side combined with a shoe, against which the hub sits, and the said shoe provided with a flange, of segmental form, over which the hook On the follower passes, the said shoe provided with a spring, which will draw the follower and latch-bolt back into place and there hold them, as more fully hereinafter described.

A is the follower, perforated for the spindle, as at B, and constructed with two arms, C C, to act upon the respective arms D of the yoke to draw the latchbolt E, in substantially the usual manner. The `follower is of such thickness as to move freely between the plates door it would be difficult to bring the follower to the position for the insertion of the spindie. TO insure retaining in this position, as also to automatically draw the latch-bolt back into the case, I construct the follower with a hook, a, upon the rear, and in the rear of the follower I arrange a shoe, F, with an upwardly-projectin g fia-nge, f. This shoe lits the sur# face of the follower and forms a seat, as it were, upon which to turn. The hook a sets over the fia-nge f, and the flange is of a seg'-` mental form, so that, in turning'the follower, the hook will traverse around upon the said flange. This shoe is preferably pivoted at b to the case, and a spring, d, arranged in connection therewith, the tendency of which is to hold the shoe in the position denoted in Fig. 1, and support the follower in proper position. In this position the latch is operated in the usual manner. Toreverse the latch, take hold of the bolt and draw it from the case, as denoted in broken lines, Fig. l. This draws the operative parts forward, as also denoted in broken lines 5 the latch-bolt may be properly set and left free 5 the spring on the shoe will return the bolt and operative parts into place.

I claim as my invention- 'Ihe follower A, constructed with the hook a, combined with the shoe F, constructed with the segmental flange f, and arranged and operating together substantially as specified.
