R E m E STATES LOCK.
Specification of Letters Patent.
Patented Apr. 11, 1916.
Application filed June 28, 1915. Serial No. 36,817.
T 0 all to hom it may concern Be it known that I, ROY R. ALBRIGHT, a citizen of the United States, residing at Torrington, in the county of Goshen and State of lVyoming, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had to the accompanying drawings.
My present invention relates to new and useful improvements in locks and has particular reference to a device of this character which is especially adapted for use in connection with doors of houses, barns or any other buildings.
One of the principal objects of the invention is to provide a lock wherein the lock bolt is provided on both its upper and lower edges or faces with rack teeth which are engageable by the ribs on the terminal of the ey so that this latter member may be turned in the lock to project or retract the bolt.
Another object of the invention is to construct an efficient lock which is designed with such regard to proportion, number and arrangement of parts, may be cheaply manufactured, will be durable and eflicient in service, and may be readily applied to or removed from any door.
The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more part1cularly pointed out in the claim which is appended hereto and form part of this application- With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a side elevation of the lock, illustrating the same as being applied to a portion of a door, which is shown in dotted lines; Fig. 2 is a longitudinal vertical section taken medially through the lock; Fig. 3 is a section on the line 33, of Fig. 1; and Fig. 4 is a detail view of the key, looking at the grooved terminal thereof.
As embodied in the accompanying drawings and as best shown as an entirety in Fig.
2 thereof, the lock of the present invention consists generally in a casing 10, and a lock bolt 11. The casing 10 is preferably rectangular in shape, although it may be of any other design, without departing from the splrit of the present invention. The lock may be formed from sheet or cast metal, as
desired. The face plate 12, which is secured to the outer end of the casing, terminally extends beyond the upper and lower walls of the casing and is provided in its extended portion with apertures, indicated at 13. Bolts, screw or equivalent fastening devices may be passed through these apertures for securing the lock casing against withdrawal from the door, as disclosed in Fig. 1.
In the face plate 12 and at the approximate center thereof, is formed a rectangular opening 14:, through which the lock bolt 11, which member is rectangular in cross section, is slidable.
' The lock bolt is provided with a longitudinal bifurcation 14, which extends from its inner end and receives a guide web 15, which traverses the space between the side walls of the casing and obviously serves in the manner best disclosed in Fig. 2 to maintain .the lock bolt in horizontal position, while it is projected or retracted.
Both the upper and lower edges or faces of the lock bolt are provided with a longitudinal series of rack teeth 16, which are engageable by the ribs 17 formed on the terminal of the lock key, shown in detail in Fig. 4 and designated by the numeral 18. This key is preferably formed from a cylindrical plug or blank of metal and is provided with a plurality of longitudinal extending, circumferentially spaced grooves at its outer terminal, in order to produce the circumferentially spaced ribs 17. Referring now particularly to Fig. 3, it will be seen that the ribs of the key really transform the terminal of the key into a cog wheel or pinion so that the key, when rotated, will cause the projection or retraction of the lock bolt. Extending horizontally from the vertical wall 20 of the casing 10, is a stud 21 which is located immediately above the upper edge of the lock bolt, as in Fig. 3. Extending horizontally from the wall 22 of the casing, is a stud 23, which is located immediately below the lower edge of the lock bolt. The wall 20 is provided with a key hole 24:, while the wall 22 is provided with a key hole 25. The terminal of the key is, as shown in Fig. 45 provided with arecess or socket 26, which is adapted to receive either the stud 21 or 23, when the key is inserted in the lock. Obviously, the studs serve to maintain the key in the proper position so that it will rotate about a relatively fixed axis when being manipulated to project or ,retract the bolt.
Upon reference to Fig. 8 it will be seen that when the door is to be opened from the out side of the building, the key is inserted through the lower key hole and engaged with the stud 23, after which it is rotated to re tract the lock or (in case the door is to be locked) to project the bolt. If the door is to be locked, or unlocked from the inside of the building, the key is inserted through the upper key hole, engaged with the stud 21 and then rotated in the desired manner.
The merits of the present invention will, it is thought, now be obvious in view of the foregoing description and the accompanying drawings, for it will be seen that the lock is relatively simple in construction, but is so designed that it may not be opened by any other, than an authorized person possessing a legitimate key to the look.
In reduction to practice, it has been found that the form of this invention illustrated in the drawings and referred to in the above description as the preferred embodiment, is the most ellicient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in the details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the ad- Copies of this patent may he obtained for vantages of this invention, as defined by the appended claim.
What is claimed is:
A look including a casing, a lock bolt slidable therein, said lock bolt having a longitudinal bifurcation in one end thereof, a guide web traversing the space between the side walls of the casing and disposed within the bifurcation for maintaining the bolt in a horizontal plane, rack teeth formed upon the upper and lower edges of the bolt, the opposed walls of the casing having upper and lower key holes formed therein, a key provided with a plurality of circumferentially spaced longitudinally extending ribs, said key being insertible in either the upper or lower key holes for engaging the ribs with either the upper or lower rack teeth, said key being rotatable when the ribs are engaged with the rack teeth for projecting or retracting the bolt, the terminal of said key being provided with a socket, and studs extending from the inner faces of the opposed walls of the casing in alinement with the key openings, said studs being received in the socket oi the key when the key is applied to the lock, there being a stud in horizontal alinement with each of the key holes to retain the ribs of the key in engagement with the rack teeth.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
