LOCK.

SPECIFICATION forming part of Letters Patent No. 545,418, dated August 27', 1895.

Application filed October 29, 1894. Serial No. 527,243. (No model.)

.b all whom it may concern.:

Be it known that I, FRANK SOLEY, a citizen of the United States, and a resident ot Philadelphia, (Frankford,) in the county of Philadelphia and State of Pennsylvania, have inventcd certain new and useful Improvements 1n Locks, of which the following is a specification.

My invention relates to cylinder-locks applicable to all purposes, such as latch-locks, dead-locks, drawer-locks, truuklocks, and lock-boxes. The object of my invention is to generally improve the construction of cylinder and latch locks, and in orderto enable others skilled in the art to which my said invention appertains to understand and use the same I will proceed te describe the details-of its construction, explain its operation, and point out in the appended claims its novel characteristics.

Referring to the accompanying drawings, in which similar characters of reference indicate corresponding parts throughout the several views, Figure 1 is an elevation at the back of a latch-lock, showing the end of a cylinder made according to my invention, which is intended to project through the door in the manner usual. Fig. 2 is a similar view with the cover and cylinder removed. Fig. 3 is a horizontal section on the line .sa ar, Fig. 1. 4 is an elevation at the back with the cover and latch-bolt removed, showing the throw-o device. Figs. 4ta and 4h are detached perspective views of the parts of the throw-oit device. Fig. 5 is an inside end View of the cylinder, showing my improved manner of attaching the roll-back to the cylinder. Fig. 6, which, together with the remaining views, is enlarged, shows the outside end view of the cylinder removed from the shell. Fig. 7 is a cross-section on the line y y, Figs. l0, 12, and 13. Fig. 8 is a cross-section at .c .e in Fig. 9. Fig. 9 is an inverted plan view of the cylinder. Fig. 10 is a side view of the cylinder. Fig. 11 is a horizontal section of the cylinder in the plane as az', Fig. 10. Fig. 12 is a side view, partly in section, of the cylinder and shell, the dog being removed and showing a special key inserted. Fig. 13 is a similar view showing the master-key inserted.

Fig. 14 is a horizontal section of the cylinder, taken similarly as in Fig. 1l, showing a modiiication of the dog.

Referring to Figs. 1 to 5, inclusive, the lock s frame or housing A is constructed with the usual removable 'cover I3, bearing the cylinder-shell C, containing the cylinder` D. The latch-bolt E is actuated bythe roll-back 2, which is attached to the inner end of the cylinder D by the upset tenen 3, entering the mortise ofthe roll-back, attordinga stron g and cheap construction. The latch-bolt E is reversible, so as to strike either way, to adapt it to a door opening outward or inward, the bevel 4e being placed as desired when the lock is put together. the bolt E has its shank 5 central, as seen in Fig. 3, and its spring 12 axial to the bolt snpported on stops 13 l1, and its two sides are symmetrical, and double sets of lugs 6 6 7 are provided for the roll-back to engage with. The throw-ott handle F has its shank 8 movable in the length oi' the slot 9 and inserted into the bolt-shank 5, as indicated in Figs. 2, 3, and 4. A squared part 10 of the shank 8 carries the holdback 11, being upset over its squared hole, Figs. la and 4b, and said holdback is composed of a spring bearing frictionally against the inside of the housing A and catching in a recess 15 therein when turned to the position indicated by dotted lines in Fig. 4, engaging with the stopA 16 after the bolt E has been thrown back and itis desired to prevent locking.

p Referring to Figs. 6 to 13, inclusive, the cylinder D is mortised at 20 to receive the tumblers 2l and dog 22, and the keyhole 23 in the cap 24 is formed at right angles to the tumblers, so that the notches 25 in the end of the key shall determine the position of the tumblers. The tumblers 2l are pivoted on the pin 26 and each is provided with aspring 27, thus holding the group outwardly against the cap 24, and when the key 28 or 29 is inserted its inward movement is limited by stops 30 abutting on the cylinder D. Mortises 31 are cut into the sides of the mcrtise 2O to receive and guide the key by means of its fork 32. The shell C has a flange overlapping the cylinder D, and the aperture 34, Fig. 1, is of less diameter than the span ot' To afford the reversibility ZOO the stops 30 of the key. The key is inserted, its stops 30 passing through the notches 35, Fig. 1, in the flange 33, and then being turned the stops 30 pass behind the flange 33, which enters the notches 36 behind the stops, retaining the key against the springtumblers. rlhe tumblers may be provided with one or more sets of notches, as desired. Two are illustrated, one set being aligned in Fig. 12 with a special key 28 and another set being aligned in Fig. 13 by the master-key 29. The dog 22, pivoted at 40, is pressed with moderate tendency toward the tumblers by a spring 41, sufficient only to push the spur 42 into the notches of the tumblers when aligned. The dog engages with the mortise 43 in the shell C to lock the cylinder D. The movement of the dog 22 whereby it engages and disengages with the shell C is independent of the rotary movement of the cylinder, and for this purpose I provide square shoulders 44 44 upon the sides of the dog 22 and corresponding shoulders or sides in the morlise 43. A rotating force applied to the cylinder D can thus have no effect upon the pressure of the dog 22 against the tumblers 2l.

In Fig. 14 the modication consists in utilizing the springs 27 for both the tumblers 2l and the dog 22 by providing the latter With a spur 50, against which the springs all bear. A filling 5l is also shown in Fig. 14 to intercept external access to the dog 22.

In Figs. 7 to 14, inclusive, the tumblers 2l are shown in the form of segments, which are advantageous in point of simplicity and cheapness of construction and convenience of setting up.

The cylinder D is kept in place by means of a groove 65, extending partly around its circumference, and a stud-screw 66, inserted through the shell Cinto said groove, which is advantageous over former constructions having a slot in the shell and a screw-stud in the movable cylinder, which is liable to work loose.

IIaving thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a cylinder lock, the combination of a rotary cylinder, a shell, a mortise in the shell,y

segmental tumblers pivoted in the cylinder, a locking dog pivoted in the cylinder beyond the arc of said tumblers engaging with said tumblers and controlled thereby to enter or withdraw from the said mortise, and means independent of the rotation of the cylinder tending to move the dog out of said mortise toward the tumblers.

2. In ay cylinder lock, the combination of a rotary cylinder, a shell, a mortise in the shell, segmental tumblers pivoted in the cylinder, a dog in the cylinder pivoted beyond the arc of said tumblers and controlled thereby to enter or withdraw from the said mortise, and

`a spring tending to move the dog out of said mortise toward the tumblers.

3. In a cylinder lock, the combination of a cylinder, a shell, a dog in the cylinder adapted to lock with the shell, a series of tumblers pivoted in the cylinder and formed in true segments with their arcs containing notches located in the arcs of the segments and engaging with the dog.

4. In a cylinder lock, the combination of a cylinder, a shell, a dog in the cylinder' adapted to lock with the shell, a series of tumblers pivoted in the cylinder and formed segmentally with their arcs containing notches variably located and engaging with the dog; said dog` being also pivoted in the cylinder and having a spur engaging with the several notched arcs of the tumblers.

5. In a latch lock, the combination with a suitable housing, and a latch bolt, of a throwV off device consisting in a suitable external handle and 'its shank connected with the bolt, and rotating on an axis at right angles to the length of the bolt, and movable with the bolt in the direction of the length thereof, and a segmental spring plate bearing frictionally on the housing, connected rigidly to the shank of the said handle so as to rotate therewith, and a suitable stop in the housing with which the plate is adapted to engage by rotation when the bolt has been drawn back by the handle, and the latter partly rotated to throw oft the latch.

6. The rotary cylinderl provided with the retaining groove 65, therein, and the fixed shell provided with the retaining stud 66 for limiting the rotary movement of the cylinder, substantially as shown.

7. In combination, a cylinder' having a mortise, a pack of tumblers pivoted in said mortise and disposed in parallel lines with the cylinder, mortises, as 3l, formed in the sides of the cylinder mortise to receive and guide the key, and a key having a fork adapted to enter mortises 3l, substantially as described.

Signed at Philadelphia, in the county of Philadelphia and State of Pennsylvania, this 24th day of October, A. D. 1894.
