LOCK.

To all whom fit ma/y concern:

Be it-,known that we, HARRY H. LYON and. WALTER W'. LYON, citizens of the United States, residing at New Albany and Towanda, respectively, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to improvements in locks, and more particularly to automatic controlling means therefor.

` The primary object in view is the control of a lock from a distance relative to varying conditions, as the control of a toilet door lock relative to the movement of a car.

Y lith this and further detail objects in view as will in part be set forth and in part become obvious, the invention comprises certain novel constructions, combinations and arrangements of Darts as hereinafter disclosed and claimedl.

In the accompanying drawings,-Figure 1 is a view in side elevation of a fragment of a car axle illustrating in elevation a gov ernor in its relation to the lock controlling switch together with the lock, the. casing of the latter being shown in section for disclosing interior structure. Fig. 2 is an edge view of one of the sections of the governor collar detached, a section of the switchthrowing collar being seen in dots. Fig. 3 is a planA view of one of the governor weights and connected parts detached. Fig. 4 is a detail, transverse section through one of the slide rack bars. Fig. 5 is a detail, perspective view ofthe washer of one of the governor weight retaining bolts. `Fig. 6 is a horizontal, detail section taken along the upper edge of the casing and showing in top plan the night latch slide, the upper end of the key actuated finger of the latch beingl seen in dots. Fig. 7 is a detail elevationof the knob operated parts, some of the same being spaced for clearnessy of disclosure. Fig. 8 is a plan view of the hub engaging pawl. Fig. 9 is` an end view thereof.

Referring to the drawings by numerals, 1 indicates an ordinary lock case into which extends the squared hollow, knob shafts 2, 2, the` inner end of each engaging a hub 3,and one of the hubs 3. being provided with a boss 4 rotatably mounted ina recess in the other hub. Each hub 3 is provided with an outwardly extending boss 5 rotatably Specification of Letters Patent.

mounted in the side walls of casing 1 in condition for retaining the hubs 3 in proper position. The squared shaft-s 2 are retained in place by securing bolts 6, 6, extending therethrough, and threaded into the respective hub 3, and the knobs are retained on the shafts 2, each by its usual retaining bolt engaging in one of recesses 7 formed in the respective shaft.

An ordinary latch 8 projects from the edge of the casing 1, and at its inner edge pivotally engages an operating lever 9 normally retained by a spring 10 in condition for positioning the latch 8 at the outer limit of its movement. An upstanding finger 11 projects from the upper end of lever 9 and lies along side the key hole 12, in position for being shifted by the key for drawing the latch 8 inwardly). The lever 9 is pivoted near its upper end, as at 13, and is provided with an arm 14 extending laterally from the upper end and arched as at 15 in the usual manner over the hubs 3, said hubs being provided each with a pair of shoulders 3 either of which is adapted to engage the arm 14 and elevate the same when the respective hub is rocked or oscillated, the elevation of lever arm 14 swinging the lower end of the lever 9 inwardly, and thus retracting the latch 8.

A night latch 16 is pivoted as at 17 within the casing 1 and is provided with a pin 18 engaging a retainingI spring 19 adapted to retain the latch at either extreme of its movement. The lower end of the latch 16 is positioned for swinging to a point immediately above the free end of lever 14. A slide 17 is pivotally connected at one end to latch 161, and in its lower faceV near the other end is formed with a recess 18 terminating at its outer4 end in a shoulder 19. A pawl 20 is pivoted to slide 17 and pressed by spring 21 into position for having its free end extend past a portion of the recess 18, excess movement of pawl 20 being prevented by a retaining lug 22 projecting laterally from slide 17. Slide 17 is retained in position by lugs 17 and 23` extending laterally from the easing 1. Thus if the night latch is thrown with its upper end to the right, that is with the lower end above lever arm 14, and a key is introduced through key hole 12 and revolved, the key will iirststrike shoulder 19 and throw the slide toward the left, thus swingingthe latch 16 to the released position and the furthervmovement of the key will then retract latch 8.

A lug 24 extends inwardly from the rear edge wall of the casing l, and a catch lever 25 is pivoted thereto, as at 26, the lever 25 being formed intermediate its length into an armature 27 disposed immediately above the electro- magnets 28, 28. The inner or free end of lever 25 is formed with laterally extending projections 29, 29. Intermediate the length of the armature 27 are arranged eyes 3l, 3l, the upper one of which is engaged by a spring 32 normally maintaining the armature in an elevated condition. Vhen the lever 25 is so elevated, the upper projection 29 extends into a notch 33 in one of the hubs 3, such hub being thus retained against oscillation. As both projections 29 lie in the same vertical planes, one of said projections will engage the notch 33 in one hub 3, and when the lever 25 is inverted the other projection 29 will be in position to engage the notch 33 of the other hub 3, so that the lock may be adjusted by a mere inversion of the lever 25 to a right or left lock, or the same adjustment may be utilized for locking either the outside knob against operation or the inside knob against operation. Assuming that the lock is to be utilized on the door of a toilet room of a car, the lever 25 will be positioned for having proj ection 29 engage the notch 33 of the outside hub 3. Obviously, when current is supplied to the magnets 28 and the armature 27 is thus energized and drawn downwardly against the pressure of the spring 32, the outside hub or hub engaged by projection 29 will be free to oscillate, and for purposes of adapting the lock to railroad car toilets or elsewhere where access is only desirable during transit, we provide a suitable electrical circuit 34 for the magnets 28, which includes a battery or other suitable source of electrical supply 35, and switch 36 adapted at times to break the circuit, one member of the switch being carried by a lever 37 provided with a roller 38 depending contiguous to the axle 39 of the car.

A collar 40 is firmly clamped onto the axle 39, being made up preferably of two semi-circular sections, as clearly seen in Fig. 2, which are clamped together by bolts 41 passed through flanges 42, 42, at the terminals of the respective sections. Oloviously, the collar 40 may be otherwise constructed and secured in position. Each section 40 of the collar is provided with paralh lel outwardly projecting arms or lugs 42', 42, vin which is journaled a shaft 43 carrying a segmental .rack 44. Each rack 44 is an exact duplicate of the other, and each is provided with an arm 45 extending, when at rest, substantially parallel to the axle 39, and terminating at its free end in a governor weight 46. Each arm 45 is provided with a concaved seat 47 having a transverse slot 48 through which extends an adjusting bolt 49 engaged by a retaining nut 50 preferably provided with the usual linger operating wings. A semi-cylindrical washer 5l is disposed between nut 50 and the seat 47 and snugly lits therein in position to rock when necessary to accommodate movement of the arm 45. The slot 48 of course is of sutiicient length to accommodate lateral movement of bolt 49 during any rocking of the washer 51. The inner end of each bolt 49 is engaged by a restraining spring 52 which extends toward the axle 39 and engages an eye 53 fixed to a lateral projection 54 formed on the respective collar section. Beneath the inner ends of the arms or lugs 42 is formed the under-cut slide-way or groove 55, which extends throughout the length of the projection 54 and in which is slidingly mounted the rack bar 56, which is formed with fianges 56', 56 corresponding to and snugly fitting within the under-cut portions of groove 55, rack bar 56 being thus held firmly against any twisting or lateral play and is guided in its longitudinal movement so as to reciprocate freely and easily. Each rack bar 56 is provided on its outer edge with teeth 56 meshing with the teeth 44 of the respective segmental rack 44. The ends of the rack bars 56 are lixcd to an annular collar 57 which surrounds and is freely shiftable longitudinally of the axle 39, the inner edge of the collar 57 being spaced from the axle so as to obviate friction, the relative position. of the collar 57 being indicated in dots in F ig. 2. The collar 57 is preferably made of two semi-circular sections secured together by bolts 58 passed through lugs 59, 59, extending rearwardly from the terminals of the sections of collar 57. The front face of the collar is thus left continuous and smooth and presents an annular surface which is adapted to be shifted bodily backward and forward along the axle 39 according to the speed of revolution of the axle. As disclosed in Fig. l, the roller 38 is disposed contiguous to and in the path of movement of the collar 57, so that when the rotation of axle 39 ceases, and the arms 45 are retracted by springs 52, the collar 57 will be projected until it strikes roller 38 and swings the lever 37 sufliciently for separating the contact blocks 36 and breaking the circuit 34. Immediately upon breaking the circuit, the armature 27 is released and spring 32 draws the lever 25 to its upper position, thus locking the respective by centrifugal force, the collar 57 will be retracted and lever 37 will be drawn over by spring 37 until the blocks 36 are again brought in contact, which, restoring the circuit, energizes magnets 28 and draws down lever 25, releasing the hub 3 and leaving the respective knob in condition for manipulation of the latch.
