To an whont zit nut concern:
Be it known that L Jos urn ITAAG, mecharr ical engineer, a citizen of the tilerman il hnpire, residing at 17 Rue des Ecoles, Villernomble, France. have invented certain new and useful improvements in a lock, particularly for railway-carriages, capable of being opened inside the door only by two distinct motions of the handle; and Ido hereby declare the following to be a full, clear, and exact description of the iiiivention, such as will enableothers skilled in the art to which it appertains to make and use the same.
This invention relates to a lock, particularly for railway-carriages, which, like some locks already known, cannot be open ed. inside except by means of two successive motions of the inner handle in such manner that any accidental opening of the lock is avoided and the danger arising therefrom removed. According to this invention the result is obtained by arrangingthe outside and inside handle each upon a separate spindle or stem which become mutually engaged by a sliding motion of the inner handle before the lock can be opened by a rotative motion of the inner handle, while outside the door the opening is eflected in the usual way. The combination whereby a vertical upward displacement of the inner handle is required before it is possible to turn it round insures the proper working of the new look, for even in the event of the spring which draws the handle downward failing to act the latter is released by its own weight from the outer handle and is again stopped.
The accompanying drawings illustrate one construction of said lock.
Figure 1 shows a longitudinal horizontal section across the whole'locking arrangement. Fig. 2 illustrates a longitudinal vertical section across the lock. Fig. 3 gives a front view of the safety contrivamze, and Figs. at and represent transverse vertical sections across the lock and the safety contrivance.
The falling-latch a, placed between the plates a andb, is drawn back outside the door by the usual handle 0 being rotated. The spindle (Z of the handle 0 is furnished inside with a cam f, which engages a notch suitably provided in the latch c, and an arm to which a rod /1 at tached by means of a joint or pivot. (See Fig. 4.) This rod is connected. with the safety device. The latter consists of a case y'A: s,
l or knob the stem m whereof provided at the inner extremity with a vertical notch or groove 11. Such notch orgroove corresponds with two feathers or ridges o and 1 the lower one of which, I, is fixed onto plate 1', ld ig. 5, while the upper one is located at the end of a spindle r. rotativoly arranged between the plates K: and s. with an arm 21, which serves as an attachment to the rod Normally the handle remains engaged by its groove it upon the lixed ridge 1), which prevents it from relating. in order to engage the groove a of the stem m and the ridge of the spindle r and to permit the rotation of the spindle r by means of the handle it is necessary to pull or push such handle/ upward. The plate j is furnished for that purpose with a slot p, which is permanently hidden by an outer plate r, which is lined onto the handle and moves with it. A. spring 1/, attached either to an inner slide-plate lined onto the handle or direct to the stem H), constantlydraws handle downward, Fig. 5; but in the event of such spring a being absent or breaking the weight of the handle itself is sul'lieicnt to bring it down.
lin doors where there is sullicient room near the front edge the safety device may be ar ranged inside opposite the outer handle (a The red A, the spindle r, and the plates [and s are then dispensed with and the ridge 1 is located or formed at the end of the spindle (Z of the outer handle, as shown in Fig. l.
The working of this lock is as follows: When the door is shut, the handle ()(JClIpiOS the position shown in lliig. .lts stem '1 is not in engagement with the ridge I but its groove a is engaged by the lined ridge 0 in such a manner that it cannot rotate nor operate the latch w. ()n the other hand, the door maybe openetl from the outside by turning the handle c ninety degrees. ln order to open the door inside, it lirstof :ll necessary to raise the handle so that the groove 1/ of the stem m may leave the ridge 0 and engage the ridge 1. When the handle/ is turned ninety degrees, the ridge 1 and the spindle r participate in the rotation and draw back the latch c by means of rod 7t. .ln the arrangement shown by dotted lines in lt ig. l the handle rotates the spindle (X. which draws back the latch 0. Upon the handle being raised the spring It becomes stretched, and upon the handle then being rotated the spring of the latch becomes compressml. When the handle is released, the iatch. is driven forward tlnch spindle r is furnished "gages the fixed ridge 0.
by its spring and causes the ridge 9 to resume its vertical position in such manner that the spring it causes the handle Z to go down, while the groove it leaves the ridge 9 and en- It will be seen therefrom that the handle Z must perform two successive1notionsviz.,a sliding motion upward and a turning motionheforc the carriagedoor can be opened from inside, and it is im possible that these two motions can be produced accidentally in the exact succession. Even a child playing with the handle Z will hardly execute exactly these two motions, which may be rendered still more diflicult by giving the spring a sufticient strength.
\Vhencver it appears desirable, the fixed ridge 0 may be dispensed with, so that it may be possible to freely turn the handle Z without operating the latch a so long as the handle Z is not drawn upward before being rotated. It is obvious that the ridge may also be arranged at the end of the stem m of the handle Z, while the groove 21. is provided at the end of the spindle or at the end of the spindle (Z.
hat I claim as my invention is l. A look for railroad-car doors comprising a spring actuated latch-bolt engaged by a tooth on the stem of the outer handle, a stem for said handle, having a straight ridge, and a slidably-arranged door-knob on the inside of the door having a grooved stem the groove being in line with the ridge substantially as described and for the purpose set forth.
2. A look for railroad-car doors comprising a spring-actuated latch-bolt engaged by a tooth on the stem of the outer handle, a stem for said handle, having a straight ridge, and a slidably-arranged door-knob on the inside of the door, having a stem with a groove in line with the ridge, and guides for the slidable knob parallel to the groove and ridge of the stem, substantially as described.
3. A lock for railroad-car doors comprising a springactuated latch bolt engaged by a tooth on the stem of the outer handle, a crankarm on said stem, connected by a rod to the crankarm of a similar stem revolubly arranged outside of the look, a projection or ridge on said stem, a door-knob on the inner side of the door arranged slidably and revolubly below said ridge, having a groove in line with said ridge and guides for the slidable door-knob parallel to the groove and ridge, substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
