Application filed February 13, 1886. Serial No. 191 ,808. (No model.)
poses where a toll is collected for the use of the cabinet or its contents.
The object of my improvement is to provide a cabinet having a coin-receptacle therein and a door for closing the cabinet,in which thelatchlock for securing said door is arranged to be operated only when a coin or check of a predetermined fixed size has been deposited therein, so as to become a part of the mechanism for withdrawing the latch-bolt, whereby. access is gained to the interior of the cabinet, and the coin, after serving the purpose of operating the latch bolt, isdischarged by the movement of the latch mechanism intosaid coin-receptacle, all as hereinafter fully described.
The accompanying drawings illustrate my invention.
Figure Us a front elevation of the cabinet, the door being shown open. Fig. 2 is a similar elevation showing the door closed. Fig. 3,
is an elevation on a larger scale, showing the interior of the door-latch. Fig. 4 is a section of the latch-lock at a. z
Ais the cabinet, having the telephone apparatus B therein. The cabinet is closed by the door 0, which is secured when closed by the latch-lock D.
E is a chute, having its mouth on the outside of the door at f, and leading therefrom to the interior of the latch-lock D. V
F is a coin-receptacle secured to the inside of the door, and communicating with the interior of the latch-lock by the chute h.
The construction of the interior of the latchlock D is shown in detail in Figs. 3 and 4, in which a is the latch-bolt, arranged to slide within the case d. b is a bell-crank lever, pivoted to the case at c, and having its longer arm arranged'to engage'the latch-bolt. e is a slot ted sliding bar, which is sustained by a spiral spring, g, arranged in the slotted portiown of the bar and abutting against the upper end of the slot, and a lug projecting from the caseinto said slot near its lower end. Bar 6 is provided I with a thumb-piece, i, which projects through a slotted opening, 1), in the lock ease and through a-corresponding opening in the door for the purposeof operating the bar e from the outside of the door when the lock is secured thereto on the inside. j is a chute arranged to conduct the coin it from outside the case 'to a point between the 'opposed ends of the sliding bar e and the lever 1 2,where it is arrested by a stop,l,projecting from the case. on is a flat spring arranged to sustain the shorter arm 'of lever b, and thereby throw outward the latchbolt. n is an opening through which the coin is is discharged into the chute h.
In operation, the door being closed and secured by the latch-bolt, the latch'bolt cannot be;operated from the outside, for the reason that the limited movement of sliding bar 0 is not sufiicient to allow the bar to reach the lever 1); but the space between the said bar and lever corresponds to the diameter of a coin, as k, or a check of like diameter representing the 7 5 amount required as toll, so that when the coin is deposited in the chute and passes to the position shown said space is filled. The lever b is then actuated by the depression of the sliding bar 6 by means of the thumb-piece i, and .the latch-bolt is drawn inward, thus releasing the door. The coin is held in position by the stop I untilthe latch-bolt is withdrawn, and it then escapes through the opening it andchute h to the coin-receptacle F. The latch-bolt may be operated from the inside by a knob, o, secured thereto. Y
By the use of this device telephone-cabinets for public use may be arranged to collect the toll without special attendants. 0
