PATRICK MURPHY, OF AMESBURY, MASSACHUSETTS.

MORTlSE-LOCK.

SPECIFICATION forming part of Letters Patent No. 321,380, dated June 30, 1885.

Application filed January 17, 1884. No model.)

To all whom it may concern.-

Be it known that I, PATRICK MURPHY, of Aniesbury, in the county of Essex and State of Massachusetts, have invented a new and useful Improvementin Mortise-Locks, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claim.

This invention relates to that class of doorfasteners termed mortisclocksj and which are inserted and secured in a properly formed cavity cut in the door-stile.

In said drawings, Figure 1 is a longitudinal section of my lock, shown as inserted in the door-stile, which is also shown in horizontal transverse section. Fig. 2 is a plan View of the look, as viewed in Fig. 1 from the top of the sheet, the cap of the case being removed and turned upside down, the interior devices being shown in plan. Fig. 3 is a transverse section of the lock-case, taken as on line A A, Fig. 1. Fig. 4 is a side elevation of one of the racks that engage and retract the bolt as they are actuated by the spindle-pinion.

In said views, a represents the shell or case of my improved lock, said case being cylindrical in form and longitudinally divided into two parts, a and a, and in the former of which the sliding belt I) is secured, the usual face-plate 0, through which said bolt passes, being secured to or formed upon said part a. This bolt is habitually forced outward for securing the door, as shown in Figs. 1 and 2, by a coiled spring, (Z, which is, in part of its length, housed in an axial bore in bolt 2), and at its opposite end bears against the head of steadyingpin e, which bears against aboss, f, formed in part a of the case, said pin being arranged within the coils of the spring. Said bolt is retracted, to release the door, by turning the knob-spindle in either direction, by means of the following devices: The tumbler h, which receives the knob-spindle, by which it is actuated in the usual manner, is formed as a pinion, it having upon its periphery a series of teeth, t, as shown. These teeth mesh with teethj, formed upon racks k k, which latter are arranged to slide in grooves arranged betwecn boss f and the inner surface of parta of the case.

Said racks are interlocked with bolt 2) by means of the angle Z, respectively formed at the inner ends thereof, and corresponding angles or lugs, m, formed upon opposite sides of the bolt at its inner end, as shown in Fig. 2; hence, when said pinion is rotated in either direction one of said racks is moved out of engagement with bolt 1), while the other rack, moving in the opposite direction, retracts the bolt. The tumbler h is pivoted in boss f of part a, and in a corresponding boss, n, in part a, as shown.

For the purpose of locking bolt 5 in position when extended, as shown in Figs. 1, 2, I employ a dog, 1;, which is engaged and actuated by thumb-piece o, whose square shank it enters acorresponding passage in eye it of the dog. Said thumbpiece o is secured in position by means of face-plate w, fastened by screws to the door. A stud, :11, formed on round portion y of the shank of o, enters a small nick, z, cut in the line of the hole in plate 10 for neck 3 and by turning said stud to the opposite side of the circle from said nick before engaging it with dog 9, the stud holds the thumbpiece in place, as it cannot, when engaged with dog p, be revolved but a small part of a circle.

It will be obvious that by actuating said thumbpiece o the end of the dog may be moved against, or removed from, shoulder s of bolt p, thereby locking the bolt in position when extended, or permiting the retracting thereof.

By forming case a cylindrical it is of less weight and cost than the usually-formed mortise-lock. It is inserted in the door at less cost, as it is only necessary to bore, with a suitable bit, a hole of the requisite size instead of cutting out a long narrow passage; and faceplaee 0, while of less than the usual length, yet admits of the insertion of the securingscrews at such distance from case a that they engage in solid wood.

The bolt-locking device consisting of the dog 19, thumb-pieee o, and its securing-plate w, furnishes an efficientand inexpensive means of effectually securing the door upon the inside when it is closed.

I am fully aware of United States Patent No. 214,080, issued to Peter H. Bakenirpril 8,

IOU

1879, and I claim nothing that is therein shown, described, or claimed, my invention differing therefrom in that my bolt is hollow or tubular, so that I house a material portion of the bolt-actuating spring therein, and I employ a guiding-pin, which is axially arranged in both the spring and bolt, all these parts being of such length relatively to the lineal movement of the bolt that all parts of the spring are at all times steadied and guided. either by the external support of the bore of the bolt or the internal support of the pin.

I claim as my invention PATRICK MURPHY.
