SPECIFICATION? forming part of Letters Patent No. 729,549, dated June 2, 1903.
Application filed November 28,1902. Serial No. 132,988. (No model.) I
To all whom it may concern:
Be it known that I,WILLIAM H. COLLINS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and usefulImprovementsin Desk-Locks, of which the following is a specification.
My invention relates 'to improvements in roll-top-desk locks; and my object is to provide the desk with a lock whereby its roll-top may be secured against further movement after it has been drawn down just sufficiently to lock the drawers of the desk.
It is frequently desirable in leaving the office gitudinal detail sectional view'of the lock and keeper, taken on line II II of Fig. 1. Fig. 3
is a longitudinal sectional view of the lock,;
taken on line III III of Fig. 2. Fig. 4 is a transverse section of the lock, taken on line IV IV of Fig. 3. y
In the drawings, 1 indicates the upper portion of a desk of any'ordinary or preferred construction provided with a roll-top 2,adapt-.
ed to lock the drawers in the usual manner. The lower slat 3 of the roll-top is provided at one end with a mortise-lock comprising atu' bular casing 4, in which is slidably arranged a bolt 5, comprising a forward round portion 6 and a flat rear portion 7, provided near its central part with mortise gear-teeth 8. Said teeth are engaged one at a time by teeth 9,- projecting from'the side of a cylinder 10, journaled at its opposite ends in the upper and.
lower portions of-casing 4E, and provided with intersecting key-slots 11 11, which extend almost to the bottom of the cylinder. Cylinder' 10 is normally held against rotation by a pin 12, slidably arranged in guides 13, secured to the interior of easing 4 and encircled by an expansion-spring 14, which yieldingly holds the rear end of said pin into one or the other of the key-slotsby pressing at its opposite ends against forward guide 13 and lugs 15, projecting from the rear portion of the pin, and which also limit the entrance of the latter into the key-slots by contacting with the side of the cylinder. Slat 3 has a counterbore 16, registering Withcylinder 10, which is partly closed at its upper end by a slotted disk 17, rotatably secured in an escutcheon 18, that is fastened by screws 19 to the slat.
Having thus described my invention, what I claim, and desire to secure by Letters Patcut, isv 1. In a desk provided with grooved side pieces and a roll-top having movement therein, the combination of a lock secured to one corner of the roll-top, consisting of a casing,
abolt slidably secured therein, comprising a round front portion and an integral flat rear portion, provided with mortise-teeth, a slotted cylinder journaled in the casing and provided with intersecting key-slots, cog-teeth on said cylinder which mesh with the mortise-teeth in the bolt, a spring-actuated pin ingand provided at its rear portion with mor- I with a beveled end for disengaging the pin rise-teeth, a cylinder journaled in the casing and provided with two slots,gear-teeth formed integral with the cylinder and adapted to mesh with the mortise-teeth of the bolt, a pin slidably arranged in guides secured to the casing and adapted to engage either of the slots in the cylinder, lugs formed integral with the rear portion of the pin to limit its entrance in the slots, a spring encircling the pin and interposed between one of the guides and the lugs of the pin, a key provided from the cylinder, and a keeper secured to one of the grooved sides and adapted to re- 15 ceive the bolt 0f the lock, substantially as described.
In testimony whereof I affix my signature in the presence of two witnesses.
WILLIAM H. COLLINS.
