CHRIST SKOLNEEK, 0F CLEVELAND, OHIO.
Specification of Letters Patent.
Aram' o Fricsrammed oct; 2e, i920.
Application-filed November 6, 1919. Serial No. 335,998.
To allevhom it mag/ concern y Be 1t known that I,- CHRIs'r SKOLNEEK, a subject of theV Government of Courland, in
the Baltic Province residing at Cleveland,
in the county of uyahoga and State of Ohio, have invented certain new and useful hnprovements in Locks, ofwhichv thev following is a specification. Y
This invention relates lto a lock' for doors and particularly to that type of lock which is commonly mortised within the frame work of the door, but which may with slight modifications, be applied to the exterior thereof.
The lock consists of that type in which a plurality of tumblers are pivotally secured and which must be brought into a predetermined position by the turning of the key before the bolt may be moved.
Further and more limited objects of the invention consists of means employed for operating the tumblers and bolt, the arrangement of the parts being such as to obviate the necessity ofV numerous moving parts ysuch as springs, levers and gears,
which are more or less commonly used in this'type of lock.`
To enable others skilled in the art to make and use this improvement, the lock and its construction and Operation will now be described. f
Referring to the drawings wherein likek reference numerals designate similar parts of reference throughout the various views, Figure 1 is an elevation of alock with the cover plate removedg'Fig. 2 is a horizontal section on the line 22 of Fig. 1 and looking in a direction of the arrows ;F1gs. 3 and 4 are vsectional details taken on the corresponding lines 3 3 and 4--4 of Figs. 1 and Y, a stud bolt 5 threaded upon one side of the Vcasingll is a bolt 6. This bolt is provided with an enlarged end 7 which projects through an opening in the side of the casing and enters a correspondingV aperture in the frame work of the door casing. At the opposite end the bolt is provided with a slot 8 through which extends the stud bolt 5, and
v in this manner the bolt is supported at both ends and is allowed freedom toreciprocate longitudinally ofthe casing. At the ybottom of the bolt andsubstantially at its middle 1s provided an arcuate opening 9 which is engaged by the key whereby to operate the bolt as will be more fully described. Y
Pivotally supportedv upon stud 5 v.and
equally distributed upon each side of the bolt 6are a plurality of tumblers 10, saidv tumblers are provided with a'longitudinal slot 11, the yends of which open up-` vwardly and laterally therefrom into `notches 12 which are slightly curved concentric with the'pivot point of the ytumblers. These notches 12 are engaged by a pin 13 carried by the bolt and act to prevent the bolt from being manipulated. normally held ina locked position with respect to the bolt 6 by means of a leaf spring The tumblers 10 are 14 which has one of its ends bearing upon v the upper face of the tumblers andthe opposite end secured to the bracket 15 formed as part of the casingl. The lower faces of.v
the tumblers are `each provided with openings 16 which are concentric with the pivot point 17 of the key and which are engaged by the various portions of the key in a proper manner tol elevate theftumblers as will be more fully described hereinafter.
l The pivot point 17 for the key comprises a pin which is rigidly secured to the side of the casing 1.V The key hereinbefore referred to consists of a hollow shank '18 having a j handle 19 made integral with one end thereof and a bit 20 at the opposite end. The bit 20 is provided with a plurality of faces or steps 21 which being on a diiferent plane thereby to act in conjunction with the recesses 16 of the tumblers. Withinrthe shaft 18 is rotatably mounted a second shaft 22, this shaft is provided at that end which pro- Y jects into the handle 19 with a knurled operating wheel 23, andV at its oppositeend. v' 100 with a bit 24 which is constructed withva rions steps as described for the bit 20. With the parts constructed as above described the' s operation of the lock is as follows:
` The shaft or stem 22 of the 'key is rotated with the hollow shaft 18 by the wheel23 until the bits 20 and 24 are in perfectalin'e-A ment. The shank of the key is then insert'- ed throughthe opening 25 provided in the cover plate 2 until the pivot point 17 occu- Y pies the bore 26 of they key. The first action then is to rotate the shaft 22 until the bit 24 has engaged the tumblers 10 on one side 21 have similarly engaged and acted upon the tumblers on the opposite side of the bolt whereupon continued rotation of the key will cause the enlarged face .27 of the bit 20 Y to engage the arcuate opening 9 of the bolt and enable the bolt to be moved forwardly.
` NVhen the bolt has reached the position shown in dotted lines'in Fig. 1 the pinl is in a position to allow the spring to force the tumbler downwardly so that the pin may engage the passage l2. This then holds the bolt in a locked position 'until the operation y is reversed. Y
By the vforegoing it will be seen that a lock is provided which is simple andeilicient V'in operation, cheap of manufacture and durable, and while I have shown and delimit myself in the construction of the same further than is required bythe state of 4scribed this specic means 'I do not wish to the art or that which comes within ther sccpe of the appended claim. Y Y
claim:
- In 'a lock, the combination'of a casing,
a pin infsaid casing, a reciprocating bolt in the casing, Yhavln'g a longitudinal slotv through which said pin extends and forms Y a guide for the inner end of said bolt, avplurality of tumblers pivoted on L'Said pin, at opposite sides of the bolt, said tumblers having slots offset at their ends, and a pin Carried by the bolt and adapted to engage in the offset parts of the slots in the tumblers.v
- In testimony whereof, I do aflixrmy signature in presence of two witnesses'.y
