PORTABLE COIN-SAFE.

SPECIFICATION forming part of Letters Patent No. 449,852, dated April 7, 1891.

Application led January 3, 1891. Serial No. 376,653. (No model.) I

To all whom, t may concern:

Beit known that I, HENRY C. HART, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvementin Portable Coin-Safes, of which the following is a specification.

My invention consists in an improvement in portable coin-safes hereinafter fully described and claimed.

Figures l and 2 are side elevations at right angles with each other. Fig. 3 is a vertical section on line 3 3, Fig. 2. Figa is a bottom plan View. Fig. 5 is a bottom plan view with the base removed. Fig. 6 is a partial section on line G 6, Fig. 5 5 and Fig. 7 is a side elevation of the bottom.

A represents the body of the safe, which is a cylinder of sheet metal open at both ends, and with ears C C at the top on opposite sides and ears D D at the bottom struck up to afford space for the internal working mechanism of the device. v

B represents a slot through body A at the lower end of ears C C, of suflicient size to admit the coin for which the safe is intended.

L represents a cross-bar or disk soldered or otherwise secured within cylinder A, so as to be immovable, at about the upper end of the ears C C.

P represents flat springs soldered or otherwise secured either to disk L or to the inside of cylinder A-at the upper end of ears C C and extending downwardly and inwardly, as shown in Fig. 3, so that their inner ends stand normally within the inner circle of body A, but are capable of being pressed back into the ears C.

E represents a thimble adapted to play in the upper end of body A above ears C and disk L, and R represents a pin, the upper end of which is fastened in the top of thimble E and which extends downwardly through disk L, and is fastened at its lower end into a plunger M, whose diameter is substantially that of the inner circle of cylinder A, though the plunger M may be of less diameter if desired, its purpose being only to serve as a plunger. A spring N surrounds the pin R and acts against the thimble E and cross-bar or disk L for holding the plunger M in its highest position. The plunger is thus pressed upon by the spring through the medium of the thimble E and the pin R.

The thimble E, with its pin R and plunger M, while movable to a slight degree within the cylinder A, are all held therein by the disk or cross-bar L and are not intended at any time to be removed. The ears D at the bottom of the cylinder are, as shown in Figs. 2 and 6, shaped something like an inverted L, rising vertically from the bottom in the part marked d, Fig. 6, then running horizontally, and having a vertical projection d to form a bayonet-joint. The object of this is to lock the bottom of the safe to the body. The bottom of the cylinder consists of a base F, preferably milled to alford a hold for the fingers, from which rises a thimble F,having slots Hon opposite sides thereof and projecting lugs G below said slots.

K represents an inverted thimble lying' within thimble F and having projecting lugs I thereon, which pass through the slots H and extend outwardly as far as do the lugs G.

J represents a coiled spring lying within the thimbles F and K and normally forcing said thimbles apart, thus keeping the lugs I at the upper ends of slots H. The thimbles F and K can be placed within the lower end of cylinder A by moving the lugs I and J up through the passages d in the ears D until the lugs I strike against the upper end of said passages. This operation forces the lugs I against the upper end of the passages CZ and compresses thespring J. Then by turning the base F to the right, Figs. 2 and 6, the

spring J forces the lugs Iup into the passages Y d', when the base is firmly locked vto the cylinder until the thimble K is depressed, as hereinafter explained. The spring J, thimbles F and K, lugs G I, and passages d d constitute a bottom and a spring-catch within the body A.

In describing the operation of this safe I will assume that it is constructed to receive ten-cent pieces and to hold fifty of them, and its operation is as follows: On inserting a coin through the slot Bit passes between the lower ends of springs P, and is held by said spring. The main purpose of these springs is to prevent a coin once in the safe from rising far enough within cylinder A to register with slot B;so these springs may be,if preferred, made too light to sustain a coin between. If they are so made, the coin on being fully inserted drops into cylinder A. It the springs P are made heavy enough to sustain a coin when fully inserted, pressure of thimble E forces down spring-pressed plunger M and pushes the coin down beyond the springs P, when it drops into the safe. The coin in dropping rests upon the upper end of thimble K, upon which the coins rise one above the other, as indicated in dotted lilies in Fig. 'When a sufficient number of coins--say fifty-have been inserted to ll the body upto the slot B, pressure on thimble E causes the springpressed plunger M to bear t nrainst the upper coin, and the series of 'coins in the safe form a plunger which transmits the pressure on thimble E to thimble K, thus depressing thimble K against the action of spring J until the lugs I are forced below the passage d', when the base F may be turned to the left, Figs. 2 and 6, and withdrawn, thus opening the safe. It will thus be seen that the safe cannot be opened Without destroying it until it has received the full number of coins for which it is intended.

That l claim as my invention, and desire to secure by Letters Patent, isn

l. A coin-safe consisting of a hollow body having a slot near one end for the insertion of a coin, a spring-pressed plunger above said slot, and abottom having a spring-catch within the body, whereby on filling the body with coin the motion of the plunger is transmitted to the catch,substantially as and for the purposes set forth.

2. A portable coin-safe consisting of a hollow body A, havlng a slot therein for the in sertion of coin, a spring lying in the path of 4o .the entering coin, a movable spring-pressed plunger at one end of the machine, and a springcatch holding the bottom at the other end of the safe, substantially as and for the 'purposes set forth.

3. A portable'coin-safe'consisting of a hollow body A,having at one end the ears D and `the spring-catch bottom F, F, and K, having therein the lugs G and I, having at the other end a movable springplunger, and having a 5o slot for t-he insertion of the coin between said spring-catch bottom and said plunger, 4substantiL lly as and for the purposes set forth.
