UNITED STATES E PATENT OFFICE.
IILLIAM A. WALKER, OF RACINE,- VISCOSIN.
LATCH.
SPECIFICATION forming part of Letters Patent No. 413,422, dated October 22, 1889.
Application iiledllrlay 17, 1888. Serial No. 274,185. (No model.)
l a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented Y certain new and useful Improvements in Locking Mechanism;
and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention is an improvement in locking mechanism of the class wherein two or more locking-arms' are employed having beveled portions on their outer ends for drawing the door tightly into its seat and forming an airtight joint; and it consistspin certain features of construction whereby a cheap, durable, and effective locking device is secured.
I have illustrated my invention in the accompanying drawings, and said invention is fully disclosed in the following specification and claim.
In the drawings, Figure 1 is a perspective View of a lock, showing the back plate removed and the parts in posit-ion.` Fig. 2 is a similar view with parts removed and the spindle in section. i
A is the lock-case, of any preferred form, and is provided on its interior with the projections or lugs a a and a a2, the. latter of which form guides for a locking plate or slide B. The locking plate or slide B is formed with an aperture Z7 in one end to permit the passage of the spindle C of the locking device, and a largeraperture b to enable it to be moved byia key. The spindle and the upper face of aperture b are of such form that when brought into contact the spindle' is held from rotation by the lockingplate, and any preferred construction may be employed. In the present instance the upper face of this aperture is provided with shoulders b2 b2, adapted to tit into angular recesses in the upper face of the spindle when the plate has been forced downward by the key and prevent the spindle from rotating.
A spring D is held in position to engage the lock-plate by the lugs a a, and said plate is provided with a projection b3, which is so formed as to engage the lugo? of the lockcase and prevent the lock-plate from moving longitudinally. When, however, the key is introduced into the lock and turned, it will engage the surface of the aperture b adjacent to the spring D, and will move the plate laterally, so that the projection b3 Will be disengaged from the lug a2. A further movement of the key will move the plate4 longitudinally to lock or release the spindle C. I
The spindle C extends through lock and is provided on its inner end with a T-head E, to which the lockingarms F F are pivotally secured. These arms Vare provided at some point, preferably near their free` ends, with a slot, through which passes a headed bolt or screw, which serves' to guide them and keep them from moving away from the door. The outer end of the spindle is provided with a knob or handle, andwhen said spindle is rotated the arms F F will be retracted or pushed forward, thereby releasing or securing the door. with beveled ends, the points of which will The -arms F are preferably provided first impinge against the door-casing, and as they are farther advanced draw the door tight against the same. They may be made to engage apertures in the casing, if preferred. This forms a very desirable locking means where a tight joint is desired, and of especial value in refrigerators and similar articles.v The lock-plate B may also be ap; plied to an ordinary spring-latch by forming the actuating-spindle with recesses adapted to be engaged by the shoulders b2 of the lockplate, and by this construction a very cheap and effective lock may be secured.
What I claim, and desire to secure by Letters Patent, is-
In a locking mechanism for doors, the combination, with two sliding bars, of a spindle provided with T-shaped arms engaging said bars, said spindle being circular in crosssection and provided with angular recesses, of a single locking-plate provided vwith shoulders for engaging the recesses in said spin- In testimony whereof I affix my signature in v dle, said plate having; also an aperture propresence of two Witnesses.
vided with bearingaees to receive a key to actuate the sa111e,zmdapr0jeeti0n b3,asp1ing WILLIAM A. VALKER. bearing against one side of said plate, and Witnesses: projections a CL2 upon the opposite side of CHARLES H. LEE,
che plate, substantially as described. H. C. CASE.
