ASSIGNORS TO THE CONNECTICUT TELEPHONE & ELECTRIC COMPANY, INCOR- PORATED, OF MERIDEN, CONNECTICUT, A CORPORATION OF CONNECTICUT.

LOCK MECHANISM.

Specification of Letters Patent.

Application filed September 30, 1919. Serial No. 327,421.

- T 0 all whom it may concern:

Be it known that we, STANLEY, D. LIVING- STON and CHARLES E. STAHL,-C11J1Z6I1S of the United States of America, residing at Monden, Connecticut, have invented a new and useful Lock Mechanism, of which the following is a specification.

Our invention relates particularly to a lock adapted to be operated by a key and is shown as applied .to a pin tumbler type of construction.

The lock is particularly intended for use with automobile ignition and lighting systems but it will be obvious that the mechanism may be employed in other connections.

In its preferred form the lock comprises a housing carrying the stationary parts of the mechanism and a movable member mounted in the housing so that itmay be oscillated on its aXis by a key. inserted radially. In the preferred embodiment the movable member is in the'form of a cylinder and the key is adapted to, be inserted .through one side of the cylinder to release the pin tumblers. The key serves as a lever to rock the cylinder on itsaxis and cannot be withdrawn until the parts are in the locked position.

Figure 1, is 'a plan view of mechanism embodying our invention showing supporting members in .cross section. The parts are shown in full line in the position they would occupy when the key is insertedto unlock the parts and in dotted line in the unlocked position at which time thekey cannot be withdrawn.

Fig.2, is a front view of the locking mech anism in locked position.

Fig. 3, is arear view showing the parts in theposition intermediate the full locked and unlocked positions. I Fig. 4:, is a plan View of the housing.

Fig. 5, is a plan view of the movable member.

Fig. 6, is an edge view of the movable member.

The housing 10 may be secured to a suitable faceplate or front plate 11 in any suitable manner. 7

'The movable member 12 of the-switch is in the form of a cylinder which may be oscillated about a vertical axis in the chamber 13 of the housing. The cylinder may 'be held in the housing by atop plate 14 suitably secured to the upper edges of the Patented June 8, 1920.

with recesses 17 for the complementary parts of the pins and the balls customarily employed in pin tumbler looks. The key-way 18 for convenience in manufacture may be formed in a piece 19 inserted in the body of the cylinder 1.2 and forming, when assembled and held in any suitable manner, a part of the cylinder. v

The face plate 11 is provided with an op'eningll into which the outer edge of the cylinder 12 projects and which is large enough to permit of the swinging of the key 20 into the two positions indicated in Fig. 1. Any suitable mechanism may be operated by this key and cylinder. In the form shown an arm 21 is secured to the cylinder and the rear of the housing is cut,

away, as shown at 10 in Fig. 3', to permit the arm to swing from the full line position to the dotted line position of Fig. 1. The parts may be yieldingly held in these positions by the co-action of the inclined faces 22, 22 with the spring 23.

- This construction will be seen to be simple and inexpensive and enables the operator to apply considerable power through the medium of the key in its swinging action. Although we have shown the construction so arranged that the key may be inserted in the full line position of Fig. 1 and cannot be withdrawn when in the dotted position of Fig. .1, it will be obvious that duplicates of the recesses 15 and the pin 1. A housing having a chamber open at one side, a body mounted to-oscillate therein, -SI1(l body and housing having a row of pm tumbler recesses each of which is parallel to the axis of oscillation, .said body having a straight key slot intersecting one end of each tumbler recess and pin tumblers in said recesses.

2. A housing having a chamber, a body oscillate in said chamber, said cylinder andv sald houslng having a row of pin and spring- 40.

of the cyhnder and the housing, a bottom .row of tumbler recesses and a key plug -mounted 1n sald bodyand having a key passage intersectingsaid recesses, a plate secured to the housing and covering the outer ends of said recesses and a cover plate hold- 1ng said body 1n sald housing.

l. A housing havlng a chamber open at one side. a bodv mounted to oscillate therein,

said body and housing having a row of pin tumbler recesses each of wlnch 1s parallel'to the'axis of-oscillation, said body having a straight kev slot intersecting one end of each tumbler recess, a plate covering the outer ends of said recesses and a cover plate holding said body in said housing.

5. Lock mechanism comprising, a housing having a chamber. a-cylinder mounted to oscillate in said cl1amber, said cylinder and said housing having a row of pin and spring recesses arranged in a line extending radially of the cylinderand the housing and a bottom plate secured to the housing and closing the lowerends of the recesses. 1 6. Lock mechanlsm comprising, a' housing havlng a chamber, a' cyllnder 'mounted to recesses arranged in a line extending radially plate secured-to the housing and closing the lower ends of the recesses, and'a topcplate for securing the cylinder in the housing.

7. Lock mechanism compris ng, a housing having a chamber, acyhnder mounted to said housing having a row of pinand spring recesses arranged in a line-extending radially of the cylinder and the housing, pin tumblers in said recesses, each recess extending parallel to the axis of oscillation of the "oscillate in'said chamber, said cylinderxand cylinder, and a top plate for securing Y the cylinder in the housing.

8. Lock mechamsm comprislng, a housing, a cylinder mounted to osclllate therein, said housing and cylinder having a row of pin tumbler recesses arranged in a line extending radially 'of the cylinder, said cylinder having a key passage extending radially thereof, said cylinder being formed in two parts, one of which contains the key passage and is secured in the other part.

9. Lock mechanism comprising, a housing, a movable member mounted to oscillate therein, an arm extendingfrom said'movable member and having two inclined faces,

a spring adapted to co-act with either oneof I said facesto hold said arm and cylinder in either one of two positions and a key adapted to be inserted radially in the cylinder for operating the same.

10. Lock mechanism comprising, a hous ing, a movable member mounted to oscillate therein, an arm extending from said movable member and having one or more inclinedfaces, a spring'adapted to coact with any one of said faces to hold said arm and cylinder in oneof one or more positions and a key adapted to be inserted radially in'thecylini den for operating the same; 3
