Specification of Letters Patent.
' Patented Feb. 20, 1906.
Application filed February 18, I905. Serial No. 248,317-
1'0 all whom it may concern.-
Be it known that I, PAUL PAPENFOTH, a citizen of the United States, residin at New Britain, Connecticut, have invente certain new and useful Improvements in Locks and Latches, of which the following is a full, clear, and exact description.
My invention relates to looks and latches,-
means whereby a lock cannot be sharp instrument and particularly to a safet the bolt or latch member 0? pushed back by means of a inserted between the lock and the keeperplate when the bolt is in its home position.
The object of the invention is to provide simple, effective, and inexpensive mechanism for locking the bolt against the above method of operation.
In the-drawings, Figure. 1 is a View ofthe inside of a lock of one type constructed to embody my invention. dinal section of the same on the line a: as, Fig.
1, looking in the direction of the arrow. Fig.
3 is a sectional view of adetached detail. Fig. 4 is a plan view of a detached detail. a
The particular lock shown in the drawings is What is termed a rim-lock, but it is obvious that my invention is not necessarily confined thereto.
In the drawings, 1 is the lock-case.
2 represents the knob for retracting the latch.
' orce it forward into its normally advanced position. v v
8 is a dogging device pivotally mounted at 8 upon thelatch-bolt 4. The tail-8 of the dogging device normally stands with its end in front of a stationary abutment 9, and
when it stands in this osition it is obvious from an inspection of' ig. 1 that the latchbolt 4 cannotbe pushed rearwardly.
j 89 is apin or connection carried by the dogglng device'8 and located eccentricto its Fig. 2 is a longitumoves the pivot 8 This in 8 makes connection with the .sliding ,gui e-pin 4 of a. movable end piece 4 of the bolt 4. This mbvable end piece 4 artakes of a slight independent lon-' gi-tudina movement relatively to the bolt 4 and normally stands spaced apart slightly therefrom, as indicated in the several views. Any meansmay be provided to cause said parts to normally assume this position, one convenient means comprising a spring or springs 4 4.is a guide similar to the guide 4", excepting that the dogging device 3 makes no connection therewit in this particular case.
'From' the foregoing 1t, will be seen that when the end piece 4 is moved back against the end of the bolt 4 it will swing the dogging device 8, sothat the tail 8! will stand in the position indicated in dotted lines in F' cc of the abutment .9, in which position the bolt 4 may be retracted or pushed back. Obviously the knob 2 could not operate the bolt 4 unless suitable means of connection be pro vided between the lc'nob and the doggin device, so that the former would first re ease the dog 'n device. To that end, therefore, I provi e t e part 10, which constitutes the" latch-slide proper, the same being connected to the cross-head 5. On one side of the latchslide 10 I provide a projection 10, which is arranged to engage with the shoulder 4 on the latch-bolt after said slide has moved a short, distance. I also provide a shoulder 10 which engages with the eccentric portion of device 8. This shoulder 10 ogging device on the first part of its rearward excursion, whereby said dog g device will be released before the shoulder 10 engages with the shoulder 4. When this occurs, the continued rearward excursion of the latch-slide 10 will draw the bolt, the latter being then free to retract.
11 is the keeperlate, into which the bolt is projected when tlie lock is in operation. rom-the foregoing it will be seen that a sharp instrument inserted between the lock and the keeperlate cannot be successfully em loyed to push back the bolt, because norma ly the dog 8 stands in front of the stationary abutment 9.. H
I have shown my invention in its preferred the doggin form;but manifestly it may be employed in various ways withoutdeparting om the 4 spirit and s00 ried by said bolt and opera e thereof. For example, it is not essential t at the end iece 4 should -p1oject'beyond the end of t 'e bolt 4, it bein merely essential that it should be so locate or placed as to be inaccessible to anyonewho should attempt to push the bolt back by inserting a thin instrument'between the edge of-the door and What I claim is 4 1. In a device of the character described, a movable bolt, an independently movable piece carried thereby, a dogging device care by said independently-movable piece, a manually-operative device, a connectionbetween the same and said bolt, said connection also operating said dogging device, I
2. In a device of the character described, a movable bolt, a dogging device carried thereby, an inde endent movable member carried by sai bolt and engaging said dogang device to operate the same, and a latch-s 'de operatively connected Withsaid dogging device and said bolt. 1
3. In a device of the character described, a movable bolt, a dogging device carried thereby, an inde endent y-movable member carried by sai bolt and engagin saiddogging device to operate the same, a atch-slide opthe door-casing.
eratively connected with said dogging device and said bolt, and means to cause said latchslide to operate said dogging device in advance of said bolt.
4. In a device of movable bolt, an independently mova piece carried at the endthereof, and normally spaced apart slightly therefrom, a dogging device connected to said inde movable piece, a manually-contro ating device, a connection between said operating device and said bolt and dogging dethe character described, a ble means'for normally moving the end piece,
direction to set the dogging deiend' piece in a connected with both the bolt and said dogging device whereby the latter may be reeased and the former retracted.
