LOCKING MECHANISM.
Patented Nov. 15, 1910.
Application tiled February 28. 1910. Serial No. 546.290.
Monroe and State of New York, have invented certain new and useful lmprovcments in Looking .\lccha1usms. ot \l'llltll the following a specification.
This invention relates to locking mechav nism for use in connection with receptacles.
bottles or other articles, the locking mechanism being so arranged as to permit an outer door of such a receptacle to be opened f for the insertion of the article and to belocked by the closing of the door after the insertion of the article, so that the door cannot again be opened until the locking mechanism has been released by an appro-' priate operation from within the receptacle or the building in connection with which it is used. i v
The object of the invention is to produce a mechanism of the kind above referred to which shall be simple, compact. and inexpensive in construction, and convenient and reliable in operation, and to this end the invention consists in the locking mechanism hereinafter described, as the same is defined in the succeeding claims.
In the accompanying drawings, which illustrate the preferred embodiment of the invention: Figure 1 is a vertical elevation of the locking mechanism showing parts thereof in section, and showing in Section a portion of the receptacle in which the mechanism is usedg and Figs. 2 and 3 are views similar to Fig. 1. showing the parts in different operative positions.
In the illustrated embodiment of my invention the locking mechanism is applied to a cupboard or receptacle formed in the wall of a building. the upper portion of the reeeptaclc, including its top or ceiling 1. being shown, and'the receptacle is provided with a door 2 accessible from within the building and'a door 3 accessible from without the a lever pivotedat 6 upon a casing 7 fixed to the inner surface of the outer door The latch has a short arm projecting into the casing T, where it is engaged by a compression spring 8 which tends constantly to move the outer arm of the latch downwardlv and into engagement with the. latch keeper. At its inner extremity the latch is provided with a shoulder 10 formed to interlock with the keeper. and with an inclined surface ll adapted to ride over the keeper. such as are provided for the deposit ot milk Between the shoulder l0 and the surface 11 the 1: tab is provided with a notch 12 which I eoiiperates with a trip by which the latch is The. keeper 18 in the form of a tag :3 mounted on a plate 9 secured to the released.
wall of the receptac e.
The mechanism for releasing the latch comprises a trip 13 which is pivoted at 14 upon a horizontal slide rod l5. rod moves in hearings in the keeper and in a second lug 16 on the plate. 9. The rear end of the. rod is also guided in a lug l7 fixed to the wall of the receptacle. spring 1 engaging the forward end of the slide rod. tends to cause the slide rod to fol low the inner door :2 for a short distance when the door is opened.
in the normal position of the apparatus ;the latch rests with its notch litupon the upper cml of the trip, as shown in Fig. l.
and. under such conditions. the outer door is unlocked. since the shoulder 1 on the latch is held clear of the keeper. 'ith the parts in this position. if the outer door he opened the latch is disengaged from thetrip and drawn over the keeper. fter the door has been so opened. if it he closed again. the inclined surface ll on the latch rides over the keeper. and then engages the upper end of the trip. The trip is llllls pushed back into inoperative position. as shown 'in Fig. 2. before it can engage the notch l2. and the spring 8 then acts to force the latch down with its houlder 10 in locking engagement with the keeper. and the outer door is thu locked and annot again he opened until the trip has been operated to release the latch. The trip at this time is prevented from ..\vinging too far back hr means of a downward projection 19 which engage the rear sid of the keeper as shown in Fig. 2. When the inner door 2 of the receptacle is opened. the spring 18 forces the slide rod rearwardly. or to the right as shown in Fig. 3.
thereby withdrawing the trip from the c mpression The slide latch. As the rod nears the right-hand limit of its movement, the tripengages a lag fixed on the plate 9, and this swings the keeper forward into a position in which its upper end may pass freely beneath the end of the latch. .The trip is prevented from l .2 v 1 .em-wamemhersmounted upon the door, and a'trip ada )ted to be set to en age the latch and hol the latter normal y free from the keeper so long as the door remains in closed lposition, the latch being formed and arranged to engage the trip when the door is.
. swinging too far in this direction by enl opened and again closed, and to throw the 70 'gagemont-of the downward projection 19 with the lug l6. \lith' the parts in the position of Fig. 3, if the inner door he closed. the slide rod is moved forward by the engagement of its rear end with the door. and
the trip is thus carried forward until its upper end engages the rear surface of the;
keeper. During the continued movement of the slide rod the end of the trip first. slides upward along the surface of the keeper and into engagement with the notch 12 in the latch. and then raises the latch into the position illustrated in Fig. 1, and the mechanism f is thus reset for a new operation.
It ls-des' 'able to provide suthcient res1stance to the movements of the outer-door to to i hand when necessary to release the locking? \Vhde, therefore, it is prcfcrj trip into ino erative position to permit the l latch to inter oek with the keeper.
2. Locking mechanism having, in combination with a door, a latch and a keeper arranged in cotiperating position, the latch being monntcd' upon the door, and a trip adapted to be set to engage the latch and hold the latter normally free from the v keeper, so long as the door remains in closed position, the latch having an inclined Slllfare formed to ride over the keeper and an i gage the trip and throw the latter out of operative position, when the door is moved I from open to closed position to permit the l latch to intcrh ck with the keeper.
{ 3. Locking mechanism having, in combiprevent it from being opened andclosed by nation with a door, a latch movably mountaccidental causes as, for example, by the aced on the door, a stationary keeper arranged 'tion of the wind. For this purpose a detent 9 in position to cooperate with the latch, 21
'21 is mounted upon the. front of the keeper.
ated, in the illustrated embodiment of the.
invention, by means of the inner door, it is not necessarily so operated.
ample, the slide rod might be actuated by mechanism. able to operate the releasing mechanism automatically by means of an inner door, this feature of the device is not essential to the invention.
The hcroinheforc described mechanism is simple and yompact, and all of its mechanical parts, eltccpt the latch, may be mounted and connected together in a self-contained form, that is to say, without separate attachment to the wall of the receptacle.
y-invcntion is not limited to the embodiment hcroinbefore described and illustrated in the accompanying drawings, but may be embodied in various other forms within the nature of the invention as it is defined in the succeeding claims.
I claim 1. Locking mechanism having, in combination with a door, a latch and a keeper aranged in cooperating position, one of said If the inner door 2. in the drawings were omitted, for ex a slide. and a trip pivotally mounted upon the slide and adapted to cotiperate with the latch, said latch having a notch adapted to be engaged by the trip when the latter is operated in one direction whereby the latch will be raised from the keeper, and the latch 1 also having a surface arranged to engage the ltrip and tlu'ow'the latter into inoperative position when the latch is moved by the clos- 5 ing of the door.
5. Locking mechanism having, in combination, a spring-controlled latch, a keeper cooperating with the latch, means for tripping the latch. and a detent arranged to engage the latch in front of the keeper and to frictionally oppose the movement of the latch into and out .of engugement with the keeper. v i J.
