The top of the channel 1- the line 4 -4 of Fig. 2 viewed-from the left. l does not narrow as much as. the bottom and Fig. 5', is 'a vertical cross section through l hence the sido of the channel is inclined the line 5 -5 of Fig. 1 ih engagement withl from the botten outward. 'lhe channel of `4s55 the frame member as in Fig. 2 viewed from l the recess member is the sanne shape and lic-s 11o in the same position with respect to the apex and base of the recess. The lugs are shaped the same as the channels, and are madeilarge enough to Wedge in -nnder the pressa re ot the latch bolt. The face opposite the channeled face of the member 22 is notched as at 26 and a Wall 27 is left between the notch and the plate 23.

rl`he arm 13 of the latch-boltiis notched on the side adjacent the faceI plate and forms a collar 28 in its attachment to the barrel7 1l, the notch and collar forming achamber 32 for the coils of the spring 29,

which engages around and is fastened at one end to the barrel 11; the other end is hooked around post 9. A square perforation 30 is provided in the barrel and in this fits a shank 31 of a knob or handle which turns the barrel 11. This oscilla-tes the arm 1-3 in the arc of a circle as far as the stoppost 10.

33 is a pivot with part of a lever, which may be attached and used as a connection with a. `hand lever inside the carriage;

The movement of the arm to the stop post completely withdraws the latch-bolt from the recess 14, and after the grip on the han dle is released the spring causes the latch boit to.rcturn`to its position in the recess 14 where it is stopped by the upper edge of the opening 19; 1

T-he members latch by swinging the door against the door stop and projecting nem#- her 22.' The bevel faces of the member 22 engaging' the beveled 'end face of the latchbolt, overcomes the tension of the spring and thebolt is forced out of the way until traveling along the face of the' projecting frame member it meets the not-ch 26. The .s1-)ring then forces it into the notch and the members are locked togetl'ier. The lugs and channels of the members are, as described above, tted to wedge together under the pressure of the latch bolt and thus form a ing case having' a recess with converging faces, one of which is provided with a latch bolt opening` a frame member adapted to fit in the recess, and lxavinga notch in one oifr'its faces, a spring-actmited bolt in said housing. adapted to be displaced by entrance of the frame nixember in said recess and to spring into the notch in the frame member, and means for withdrawing said bolt from said housing recess, substantially as described.'

Q .A lock, having in combination,- a case provided with a recess having converging faces, one of which is legged and channeled and the other provided with a. latch bolt opening,- a frame member Vhaving a recess and-.adapted to fit in the case recess, a spring-actuated bolt in said case adapted to displaeed from said recess -by entrance of the frame member therein, and 'to spring into said frame member recess and hold said member in tight engagement in said case recess, and means for withdrawing saidfbolt from said frame member recess,'` substantially as described.

In testimony whereof, I sign this specifi-- cation in the presence of two witnesses. A.
