J. R. DUMONT LOCK Filed Jan. 15, 1925 2 Sheets-Sheet l- I l m I I'll INVENTOR ATTORNEY Patented Feb. 9, 1926,
UNITED STTES PATENT OFFICE.
JOSEPH R DUMONT, OF KANSAS CITY, MISSOURI, ASSIGNOR 'lO MAUDE FRANCES DUMONT, OF KANSAS CITY, MISSOURI.
LOCK.
Application filed January 15, 1925.
To all whom it may concern:
Be it known that I, Josnrrr R. DUMONT, a citizen. of the United States, residing at Kansas City, in the county of Jackson and State of viissouri, have invented certain new and useful Improvements in Locks; andI do 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, reference being bad to the accompanying drawin 's, and to the figures of reference marked thereon, which form a part of this application.
This invention relates to looks and particularly to that class of looks used for looking the doors of compartments of rest rooms or public comfort rooms. The bolts of such locks are usually releasable upon the introduction of a check, coin or token of appropriate denomination, but unscrupulous persons not infrequently pry back the bolt with a knife or'thin piece of metal.
' My invention contemplates the provision of means for rendering it impossible to retract the bolt except in a legal manner, the legal way consisting of introducing a proper coin or token into the lock case.
The case is a continuation, in part, of an application filed by me January 15, 1923, Serial No. 612,636., in which I described sub stantially the same mechanism for preventing the unauthorized retraction ot the bolt by hair pins, shoe buttoners or similar de vices, but in the specific embodiment of that part of' the invention shown in the drawings, I have departed slightly from the exact details shown in the former application although the principle involved and the generic configuration of the detent is followed in the present application.
Inasmuch as the coin controlling and actuating mechanism is so fully described in my former application and in view of the fact that this invention has to doonly with thelbolt actuating mechanism I have deemed. it to be unnecessary to re-describe all of the coin controlling mechanism of my former application, rather will I confine it to the elements to be claimed.
In the drawings:
Fig. 1 is a front elevational view of the lock, part of the case being broken Serial No. 2,585.
Fig. 2 is a cross sectional view through the case.
Fig. 3 is an elevational view .of the lockmg mechanism with the front cover plate removed.
Fig. 4 is an elevational view of the rear side with the cover plate removed.
Fig. 5 is a perspective view of the rocking lever and the latch bar, and
Fig. 6 is a perspective view of the latch bar releasing lever and the locking bolt.
The main locking bolt 1 is slidable in the case 2 in the usual way and as is usual with such locks it is normally urged into projected or keeper engaging position by a spring 3. The locking bolt 1 is retractable by a rocking lever 4: which has a stud or pin 5 on it, normally lying against the edge .6 of a vertical sliding member 7. The sliding member has an offset groove or recess 8 normally out of line with thepin 5 so that the rocking lever cannot swing on its pivot 9. There is mechanism provided in the lock for causing the pin 10 to move in the slot 11 to raise the slide 7 when a coin, check or token is inserted in the lock case, the raising of the slide being effective in bringing the oft-set groove 8 in line with the pin 5 so that the pin can swing through the lock or recess and since this. permits the rocking lever to be actuated by the knob spindle 12 and the lingers 13 and ll, it will be apparent that the bolt 1 can be retracted because the linger 15 on the rocking lever 41- engagesa lug 1:3"ou the bolt 1, consequently a swinging movement of the rocking lever in one direction will retract the bolt. This, .01 similar mechanism, is shown in my former application above referred to.
It will be observed, both from my former application. and the present case, that unless some means is provided for preventing the surreptitious retraction of the bolt 1. the lock could be illegally o 'ierated so I have provided a detent normally in the path of movement of the bolt 1. Thedetent is designated l6 and it consists of an elbow lever having a hooked end 17 normally lying againstthe rear end 18 of the. bolt l so that the bolt cannot be withdrawn except when the rocking lever l is actuated. The hooked end 17 is normally urged into functional pos tion by a spring 19., .oneend of which is tired to the case and the other end of which bears against the elbow lover or de tent 16. By referring to Fig. 4: it will be observed that the detent is pivoted to the case at 2l and that it has a downwardly curved linger 22 lying in a slot or cut away portion 2st. In the transverse sliding bolt 25 normally urged outwardly by a spring 26, one end of which bears against the bolt 25 and the other end of which bears against the guide stud 27 .for the stem 28 of the bolt 25. The bolt 25 projects from the case so that in the event that some one attempts to tamper with the lock by introducing a knife blade, shoe buttoner or other operating means in front of the bolt 25, the bolt 2;") will be pushed rearwardly so that it will hit or press against the end of the linger 22 and thereby press the hook 17 into detaining position with respect to the bolt 1, consequently the bolt 1. cannot be retracted until the rocking lever is turned or swung about its pivot 9. The rocking lever 4: cannot be turned until the coin is introduced, as has been clearly described in my former appli cation above referred to, when the slide member 7 is raised to bring the off-set 8 in line with the pin 5. This can be accomplished when the rocking lever is swung back. The terminal or end 29 on the rock ing lever will ride on the cam 30 of the dctent to swing the hooked end 17 out of line with the bolt 1 just before the linger l5 rides on the rear end of the slot of the bolt 1 through which it projects, consequently the bolt 1 may be witl'idrawn.
It is to be understood that when. the door is closed that the bolt 25 bears against the face of the keeperin the frame so that. the spring 26 is compressed and that when the door is open thespring extends or expands so that the bolt 25 may be projected -torwardly and it is to be understood further more. that when the slide 7 is in its raised position to allow the offset 8 to align with the pin 5 it is held in that position by a latch or pawl 31 which engages the notch of the slide 7 to hold the slide in its 'aised position. then, however, the door is closed and the bolt 25 is retracted back in the lock, because its end 33 rides on the door jam, the rearward movement of the bolt 25 will impart a rearward movement of the spring arm Set rigidly carried by the bolt 25 through the medium of the bracket 35. The rearward movement of the spring will cause its end to strike a pin 36 on the pawl 31 pivoted at 37 to retract the pawl out of the notch 32, then the slide may drop into its original position to be raised only when a check, coin or token is introduced into the machine, this being effective in raising the pin 10. The pawl 31 will be thrown over into sliding engagement by ,the pivoted indicator 3S and the link 39.
The means for operating the indicator has all been described in my former application above referred to.
It will be apparent from the foregoing that the main locking bolt cannot be retracted by unauthorized persons due to the fact that the detent will eflectively prevent this and the detent can be actuated by a supplementary bolt which will also be ellective in disengaging the pawl 3t from the vertical slide member.
.Vhat I claim and desire to secure by Lett rs-Patent is 1.. A lock comprising a casing, a locking bolt in the casing, means for normally urging the locking bolt into locking position, a detent having a hooked end normally urged into the path of movement of the locking bolt to prevent its retraction, a supplemental bolt for actuating the detent to retain the hooked end away from the path of movement of the locking bolt when the supplemental bolt is in projected position and to permit the hooked end to move into the path of movement of the locking bolt when the supplemental bolt is moved to retracting position, and means for normally urging the supplemental bolt out of retracting position.
