Application led October 11, 1911. Serial No. 653,993.

To all 'whom t may concern:

Be it known that I, JACOB C. KINNEY, a citizen of the United States, residing at Prairie Grove, in the county of ashington and State of Arkansas, have invented a new and useful Lock, of which the following is a specification.

This invention relates to locks, and has for its primary object to provide a co-mbined lock and latch.

Another object of the invention is to provide a lock which is devoid of springs, and wherein the latch bolt is pressed outwardly by means of a weight mounted on a lever, which lever is in operative connection with the latch bolt.

A further object of the invention is to provide a .novel key hole guard, and means when the key hole guard is swung in positio-n to cover the key holes for preventing the latch bolt from being moved inwardly to open the lock.

Further objects will be evident from the hereinafter description.

This invention resides in the novel construction and arrangement of parts as hereinafter described and as illustrated in the accompanying drawings, wherein similar reference characters indicate similar parts, and wherein z- Figure 1 is a side elevation of the lock showing the relative parts in locked position, the face plate of the lock removed. Fig. 2 is a similar view showing the relative parts in unlocked position. Fig. 3 is a view similar to Fig. 2 showing the latch bolt retracted. Fig. 4 is a section on the line 4 -4 of Fig. 1. Fig. is a section on the line 5-5 of Fig. 1. Fig. 6 is a perspective view of the key actuated tumbler. Fig. 7 is a perspectiveview of the bell crank or lever for sliding the latch bolt. Fig. 8 is a perspective view of the key hole guard. Fig. 9 is a perspective view of the mechanism for actuating or swinging the key hole guard, the parts being separated.

Referring specifically to the drawings, the casing of the lock is designated at 10 and the latch bolt which is slidable therethrough is designated at 11, the said latch bolt sliding between the upper stud 12 and the lower studs 13 in t-he casing and through the outer end of the casing. A bell crank or lever comprising the long arm 18 vand the short arm 15 is pivoted on the pin 17 within the casing and above the latch bolt. The short arm 15 of the said lever depends into a recess 111 extending vertically through the llatch bolt which has the end walls thereof conveXed. Thus upon the lever being swung the latch bolt is slid in the casing to retract same or cause same to project outwardly from the casing. A stepped wheel comprisingthe portion 32 of smaller diameter and i the portion 81 of larger diameter is pivoted to the long arm 18 of the levers, the said wheel being mounted on a pintle 33 projecting from the said arm. A knob spindle 25 passes through the casing and has a barrel 26 mounted thereon within the casing, which barrel has the wipers 27 and 28 engaging the respective portions 32 and 31 of the `wheel pivoted on the arm 18. Thus by rotating the knob spindle in either direction the respective wiper in its engagement with the wheel pivoted to the arm 18 causes the said arm to swing upward and thus retract the latch bolt. Upon releasing the knob spindle, the wheel serving as a weight causes the arm 18 to swing downwardly thus sliding the latch bolt outwardly.

Ht-hin the upper end of Casing 10 is arranged a tumbler 19, the inner end of which is slidably mounted upon a ledge 30 proj ecting inwardly from the casing. A key hole 4t2 is provided in each side of the casing and above the said key holes the said tumbler is provided with a notch 21, with which the key is adapted to engage upon being rotated in the proper direction to shift the tumbler inward or outward. The tumbler 19 has se- -cured to the outer end thereof a weight 22 which has a lip 23 depending from the lower outer corner thereof. Upon the tumbler 19 being thrown outward the lip 23 is arranged to engage in a catch 24 at the outer end of the casing to support the outer end of the tumbler and retain the tumbler in position. Upon the tumbler being shifted inwardly the weight 22 is raised to disengage the lip 23 from the catch 24C and the tumbler is provided with a depending notched lug 20 which is arranged to seat on a `pin l19 projecting inwardly from the casing, thus supporting the outer end of the tumbler and retaining the tumbler in position when the same is shifted inwardly. This tumbler 19 is also provided with a depending linger 29 at its inner end, which finger is adapted to slide over the inner end of the arm 18 when the same is in normal position thus locking the said arm against upward movement and preventing the rotation of the knob spindle to retract the latch bolt. Thus by inserting a suitable key into the casing the tumbler 19 may be slid outwardly to lock the bell crank or lever against movement or the said tumbler may be slid inwardly to permit the said bell crank or lever to swing freely thus permitting the latch bolt to be retracted by a movement of the knob spindle.

A key hole guard 3G is pivoted in the casing below the key holes, being mounted on a pintle 45 projecting inwardly from one side of the casing, and the said guard is provided with the upstanding wings 37 and 38 fitting within the respective sides of the casing, which wings are arranged to be swung over the key holes to close same and thereby prevent the insertion of a key or other implement to actuate the mechanism within the lock. Each of the wings 37 and 38 is provided with a radial slot 39 and have the inner edges thereof cut away as designated at 41 to permit the ready insertion of the key when the guard is swung away from the holes. The wing 37 is provided with a shoulder 40 which is arranged to swing over a lug 34 projecting from the arm 18 of the bell crank upon the guard being swung over the key holes to prevent the said arm from being swung upward. In this manner the latch bolt is locked against movement upon the key hole guard being swung over the key holes and upon the guard being swung away from the key hole the latch bolt is free to be actuated in the ordinary manner. The key hole guard is actuated fromone side of the casing by means of a shaft 43 journaled in the respective side of the casing which has a disk 44 upon the inner end thereof from which a wrist pin 36 projects into the slot 39 of the 'corresponding wing of the guard, which in this case is the wing 37. On the outer end of the shaft 43 is secured a knurled thumb piece 47 by means of a pin 48 passing through the said thumb piece and the shaft. The disk 44 is preferably Hush with the inner face of the side of the casing and it is understood that the shaft 43 may be arranged in either side of the casing to permit the key hole guard to be actuated from either side of the casing as maybe desired or necessary. In turning the shaft 43 to swing the guard over the key holes the wrist pin 46 is swung above the axis of the said shaft and upon the wings of the key hole guard covering the key holes the said wrist pin is arranged to seat in the lower end of the corresponding slot 39 within the circumference in which the center of the shaft 43 lies, the pintle 45 being taken as a center. In the manner when the key hole guard is swung over the key holes the wrist pin 46 is swung past dead center thus locking the key hole guard against reverse movement whereby it is impossible to swing the key hole guard away from the key holes unless the shaft 43 is rotated. Inasmuch as the shaft 43 is operable from one side of the lock only, ordinarily the inner side of the door to which the lock is applied, it will be impossible to insert a key or other implement through the other or outer side of the lock to actuate the tumbler 19 or to otherwise interfere with the mechanism within the casing 10, and at the same time the bell crank or lever' is locked to prevent the latch bolt from being retracted. It will therefore be seen that the latch bolt may be locked by either the key actuated tumbler 19 or the key hole guard, the former being serviceable when it is desired to lock the latch bolt from either side of the casing and the latter being of especial advantage to lock the latch bolt from the inner side of the casing and at the same time to close the key holes. Vhen both the tumbler 19 and the key hole guard are utilized to lock the bell crank or lever in position to prevent the latch bolt from being retracted, it would be necessary first to swing the key hole guard away from the key hole to permit the insertion of a key or other implement into the casing and it would then require the insertion of a suitable key or other implement to free the bell crank or lever and the latch bolt to permit the said latch bolt to be retracted.

The arm 18 of the bell crank or lever passes between the wings 37 and 38 of the key hole guard and the free end of the arm 18 is arranged to strike the ledge 30 to prevent the wheel pivoted thereon from interfering with the position of the tumbler 19. A stop 16 is also provided against which the inner end of the latch bolt is arranged to strike upon the same\being moved inwardly, thus limiting its inward movement.

The wipers 27 and 28 in engaging the respective portions 32 and 31 of the wheel pivoted to the arm 18 permits the said arm to be swung upwardly readily upon the knob spindle being turned, the said wheel turning upon the pintle 33. The wiper 27 in being swung toward the said wheel swings into an approximate vertical position and upon the knob spindle being released the wheel in its downward movement slides upon thesaid wiper 27.y In this manner the position of the wheel is altered from time to time as the knob spindle is attained in an efficient manner, and it is also understood that this invention is susceptible of alterations in its details within the scope of the appended claims, to adapt same for various purposes, such as for mortise or rim locks, without departing from the spirit of the invention.

That is claimed is 1. In a lock, a casing, a bolt mounted therein, a lever pivoted in the easing and having one arm in operative engagement with the bolt, a wheel pivoted on the other arm of the said lever and serving as a weight to swing the said arm downwardly to force the bolt outwardly, a knob spindle passing through the casing, and a barrel thereon having wipers cooperating with the said wheel to raise same upon the knob spindle being rotated.

2. In a` lock, a casing, a bolt mounted therein, a lever pivoted in the casing and having one arm in operative engagement with the bolt, a stepped wheel pivoted on the other arm of the lever and serving as a weight to swing the said arm downwardly to force the bolt outwardly, a knob spindle passing through the casing, and a barrel thereon having wipers cooperating with the respective stepped portions of the said wheel to raise the same upon the knob spindle being rotated. K

3.
