Application filed April 20, 1914. 7 Serial No. 833,274.
To all whom it may concern." 7 Be it known that I, JOHN UNTERLE DER, a subject of the King of Hungary, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Locks,kof which the following is a specification. 7
My invention relates to an improvement in locks for doors and the like and has as its principal object the provision of a device which shall ofier the greatest security, to-
" gether with simplicity and cheapness of manufacture.
A further object of my invention resides in the particular arrangement and combination of parts hereinafter described.
" In the accompanying drawings :Figure 1 is a perspective view of a device embodying my invention shown as applied to a door. Fig. 2 is an elevational view showing a portion of' a door having my device applied thereto, the parts being inclosed. Fig.3 is an elevational view of a portion of the apparatus shown in Fig. 1. Figs. 4 and 45* are elevation andside views respectively of the outside of a door to which my improved lock is applied. Fig. 5 is a perspective view of a key used in connection with my lock. Fig. 5 is a view of the key shown in Fig. 5, part being shown in section.
Throughout the separate views the same part is designated by the same reference character.
Referring more particularly to the drawing, 1 is a door and 2 a door frame.
3 is a bolt fastened to the door on the inside thereof on which a metal plate such as 1 is pivotally mounted.
Fixed to the plate 4 is a knob or handle such as 5 which projects outwardly from the plate by which the plate may be operated.
6 is a catch fastened to the door frame and is a latch member shown as integral with the plate 4 which is arranged to cooperate with the catch 6 when the door is closed so as to lock the same.
Pivotally connected to the plate 4 at points 8 and 9 are locking rods 10 and 11 which run downwardly and upwardly along the door and are arranged so that their ends seat in pockets 12 and 13, respectively, at the same time the latch 7 is held by the mem her 6. The members 10 and 11, are guided and secured to the door by plates such as 14, 15, respectively. It will be seen by the arrange'ment just described that the door is held when closed at three separate points.
16 is a spring, one end of which is fastened to the plate 1 and the other end of which is fastened to the door at the point 17 The spring 16 is normally at tension and serves to keep the plate 4., together with members 7, 10 and 11 in the position shown in Fig. 1, the point of connection between the spring and the plate 1 being such as to turn the plate in the clockwise direction around the bolt 3 as Seen in Fig. 1.
From the foregoing it will be seen that when the door is locked as shown in Fig. 1, it can be unlocked by pressing down on the knob 5 or lifting up on the member 7 Members 5 and 7 being both on the inside of the door, in order to unlock the same from the'outside I have provided a bent link 18 which is pivotally connected with the plate 4. at. the point 19 so as to swing in a plane parallel to the plate. The upperend of the link 18, however, is pivotally connected to a bell lever 20 which is pivoted in turn on a fixed pin or screw such as 21 so as to turn in a plane perpendicular to the door.
Connected to the upper end of the bell lever 20 is a bolt 22 which is slightly curved so as to avoid binding when moved in its slot by the key or by the bell lever. The slot or hole in which the bolt 22 lies extends completely through the door while the bolt itself extends part way through and near its outer end is provided with an outwardly projecting pin or lug 23. It will be obvious from the foregoing that if the bolt 22 is pulled forwardly the link 18 will be lifted and the door will be unlocked.
In orderto operate the bolt 22 from the outside of the door I have provided a key, illustrated in Figs. 5 and 5*, said key having a straight stem such as 24:, in. the end of which is a central aperture 25, said aperture being so formed as to provide an inwardly projecting shoulder 26 near the outer end of the key. However, the key is slotted as shown at 27 so that when it is slipped over the end of the bolt 22 the lug 23 will pass through flie slot 27 into the recess 25 whereupon on turning the key, the lug will engage with the shoulder 26 and the bolt can be drawn outwardly to operate the lock.
As shown in Fig. 1, the door has an outer knob 28, but this is entirely separate from the locking apparatus. The hole in which the bolt 22 lies however, is shown in dotted lines at29'i-n Fig-4?. At-the outer end of the hole 29 is a plate 30 which is fixed to the door and which has an opening inregister with the hole 29.
The plate 30 carries a central pin 31 on which is pivotally mounted a second plate 32 which is'prov'ided with an aperture 33 at i the same radial distance from the. pin 31.
as the end of the hole 29. However the plate 32 isnormally turned so that. the hole 33 and tube 29 will not lie in register, The plate 32 is provided with two notches such as 3 L34: and the handle end of the key is provided with two projecting. lugs-35 -35 which may be inserted into thenotches 3434; so as to turn the plate 32 into such position that the aperture 33' will register with hole 29. Thereupon the other end of the key may be used to unlock the door.
As shown in Fig. 2,;the apparatus on the inner side of the door is normally covered by a plate such as 36'. o I
In order to lock the apparatus from within. even against the use ofa key from without, I provide a notch 37 in the plate etwhich registersfwith a hole in the door whenthe apparatus is in the locking position. shown in Fig. 1. By slipping a pin or bolt such as 38 into the notch 37 the parts are securely locked. When the pin 38 is not in use I prefer to keep it in a hole such as 39 provided in the door.
Having thus described my invention, what I claim is:
1. A locking apparatus comprising in combination, a' pivoted plate, a' latching member rigid with said plate, abolt extending partly through the door, and connections between said boltand said plate for operating the latter, said bolt having a lug,
thereon for engaging a key whereby the bolt may be movedJlongitudinally- 2. A locking apparatus comprising in combination, a pivoted plate, a latching member rigid with said plate, a boltv eXtending. partly through the door, connections between said bolt and said plate for operating the latter, said bolt having a lug thereon for engaging a key whereby the-bolt may. be moved longitudinally, and an apertured plate normally covering the end of said bolt.-
3. A locking. apparatus comprising in Copies of this patent'may be obtained for combination, a lock-ing member, a bolt extending partway'throu'gh' the door and having a lug thereon, connections between said member and. said bolt for operating the former, and a key having a bayonet slot therein for pulling said bolt forward by engagement with saidlug.
4: A locking apparatus comprising in combination, alooking member, a bolt extending partway through said door, connections between said bolt and said member for operating the latter, a pivoted plate ar-v connections between said bolt and plate for operating the latter, said bolt having means thereon for engaging 'a key whereby thebolt may be-moved longitudinally,
6. A locking apparatus comprising in combination, a plate pivotally mountedon one'faceof a door, a latching member rigid with said plate, a bolt extending partly through the door, connectionsbetween said bolt and, said plate for operating the latter, said bolt adapted to be moved. longitudinally for locking-or unlocking the door from one side thereof. V
7. A locking 7 apparatus, comprising in combination, a. pivoted plate, a latching member rigid with said plate, a bolt extend ing part way through the door, connections between. said boltwand plate for operating the latter, said bolt having means thereon for engaging a key whereby the bolt may be moved longitudinally from one side of the 1 doorto lock or unlock the door, and. means for lockingthe platefrom the opposite side.
In testimony whereof I affix my signature in the presence of two witnesses. a V
