Referring to the drawings; Figs. 1 and 2, the lettersA and B indicate respectively cylindrical bores in the edge of a door indicated fragmentally at 1, and adapted to receive and contain respectively a spring bolt housing 2, and a dead bolt housing 3.

As shown in Fig. 2, counter bores C and D intersect respectively the bores A and B. The counter bore C is for the purpose of engaging the knob spindle housing and the parts therein which coact to operate a latch or spring bolt 4.

The counter bore D is adapted to admit and retain a lock cylinder housing 7 containing parts adapted to throw a dead bolt 8.

While it is obvious that either the spring bolt or the dead bolt might be used alone without departing from the spirit of our invention, we elect to show them together in order to accomplish all the operations necessary on a typical door lock.

If the spring bolt were used alone the escutcheon plates might be circular and rela- The dead bolt 8, Figs. 30, 31, has a reduced flat portion 9 provided with a shoulder 11 adapted to limit the throw of the bolt 4 by engaging parts to be described later.

A lug 12 acts as a stop to limit the throw of the bolt in the opposite direction, by engaging the end of a slot 13 in the dead bolt housing, Figs. 20, 21, through which said lug extends when the parts are assembled.

The bolt 4 is provided with. a reduced stem member 14, Figs. 17 and 18, which is bifurcated at the end remote from the bolt. A pin 16 extends through the bifurcation to form a pivot for a link 17 adapted to be engaged and reciprocated by a crank 18 in a knob spindle 19, Figs. 32, 33.

The spindle 19 is preferably formed of rod material and is flattened as indicated at 21. The ends of the spindle are pro vided with the usual threaded holes 22 for engaging a screw to hold a knob indicated in dotted lines at 23, Fig. 4.

The reduced portion 14, Fig. 6, is surrounded by a coiled spring 24 adapted to hear at one end against the head of bolt 4 and at the opposite end against a washer surrounding stem 14.

The parts are held in operative position in a cylindrical shell 27 by ears 28 and 29,

Fig. 16, bent inwardly to form stops for i the spring pressed washer 26. A washer 31 bears against the ears. 28 and 29 on the side remote from washer 26.

When the spring bolt mechanism described is assembled. as shown in Fig. 15, it is slid into the housing 2, Fig. 13, from above, and is prevented from being drawn through said housing by an annular flange 32. Fig. The spring bolt mechanism. is now readv for interlocking engagement as a unit with other parts to be described. The housing .3 is provided with bayonet slots the purpose-of which will be later disclosed.

We will now describe the dead bolt mechanism.

The reduced portion 9 of bolt 8, Figs. 30. 31, is provided with grooves 34 formed by a milling cut. The purpose of these grooves. one of which is on either side of the member 9. is to engage with an extended leg 36 oi the bifurcated end of a key 37, Fig. 34. This groove structure permits the throw of the bolt by a key inserted from either side of the bolt and yet positively prevents any person from poking the key out of the lock from the opposite side.

While a slot extending clear through the metal would accomplish the desired result (allow the bolt to be actuated when a key is inserted from either side), we prefer to leave a web portion 38, Fig. 31, as it serves to obstruct vision through the key-hole.

By rotating the escutcheonplates 47 to the dotted line posit-ions, shown in Fig. 27, the entrance portions of the bayonet slots 48 clear theupstanding ears 49 and 51, and if the escutcheon plate or' plates be turned to the vertical position, shown in full lines in Fig.

'27; the ears 49 and 51 enter the bayonet' slots and the escutcbeon plates are secured from lateral diisplacement or withdrawal.

Rotation oi' the escutcheon plates isprevented byxa composite knob spindle housing. shown in Figs. 7, 8 and 9, which, when interlocked.v extend through holes 52 in the escutcheon plates.

The central member 53, 8, of the composite housing is cut away, as shown at 54, and two tongues 56 and 57 extend: into the cut from opposite directions.

Two ears and 59 are turned inwardly from the cylindrical wall of the housing member The members 61. 7, and 62, Fig. 9,

are adapted to slide within the member 53 from oppositeends and each is provided with a bayonet slot 63, the larger entrance portion of which will clear the inwardly bent cars 58 and 59 as the case may be and the slot portion when the members are turned engages said ears against withdrawal.

In order to lock the spring bolt housing and the composite spindle housing in a solid T or cross-head position, we insert the spring bolt casing 2 with the bolt and actuating means contained therein in the cut away portion 54 of member-53,"F ig. 8.

The parts being cylindrical, it will bese'en that when the end edge surfaces (indicated at 64) encounter the marginal wall of the cut 54(indicated at .66), the bayonet slots plane to engage the tongues 56 33 are on a and 57 if the housing 2 be rotated.

When so rotated the edgeofthe housing 2 extends into the member 53 and the entrant portions of the bayonet slots 63, Figs. 7

and 9, engaging said slots securelyagainst rotation.

It will be seen this cross-head- 'form the parts can onlybe disassembled by rotating the casing 2 from the edge of the door.
