l This invention relates ,top'telephone pay stations and more particularly toxcovers or doors for coin receptacles or boxes therefor.

Telephone pay stations at which coins are deposited by the user in payment for completed calls are provided with receptacles for the reception of thedeposited coins. In some casesstations of this type arelocatedin public places where there is no attendant.A

The door ofthe coin box is exposed and unscrupulous .persons ,sometimes break `into the boxes by prying off the door, vdrillingv into it ,or by other means. lt is, therefore,

A desirable that this door be as strong aspos- 45 sible and so formed withrespect to the open# ing in which it lits so that it will be impossible to pry the door loose from the receptacle. i

Anl object of the invention, therefor-aisl to strengthenthe cover or door. of coin receptacles so as to prevent' access to the `receptacles by 'unauthorized persons and at the same time to reduce the cost of produc-` tion.

In accordance with thisinvention the door for the coin receptacle is made of manganese steel and cast into shape to closely flt the opening of the coin receptacle. Since this casting cannot easily be drilled to attach a supporting member to the inner surface thereof, a lock supporting member having flanged ends is embedded, that is, molded into the casting at one end of the door and a pair of plates equipped with projecting ends formed into overhanging lugs are embedded, that is, molded into the other end of the casting for supporting the door at the lower edge of the opening in the coin receptacle.

This construction forms a strong closure for v coin boxes for telephone .pay stations so th at unauthorized persons cannot gain entry to thecoin boX by prying the coveroff or drilling through the hard steel door. Furthermore, the molded type of door reduces the cost of manufacture since the number of operations for assembling the door are reduced.

The invention may be more easily understood by referring to the following detailed description in connection with the accom'- panying drawing krim 11.

IFig. is a sectionalside view fof a coin receptacle to show the improved door made in accordance with this invention; Fig. -2 is a rear plan view of the `cast door showing the lock supporting member and lug plates embedded in the door;

Fig is across-sectional view of Fig, 2 on the lines 3--3y to illustrate the flanged ends of the lock supporting `member einlbedded in the cast'door; and 4 G0' Fig. 4 is a cross-sectional view ofthedoor of Fig. 20u the lines P-4 showing-the lug .plates embedded in the door. j

Referring to the drawing-infFig. 1 is shown a metallic cash receptacle 10 having 6,5 an opening in the lforwardend which is surrounded by an outwardly curved beveled v A door 12 closely fits into the beveled .rim 11 of the receptacle 10 and is formed ofyhighly refractory instal, such as '110 manganese steel; Sincey this material cany not `,easily be'machined, it is preferable .to cast-the door into a desirable shapevto fit the opening andas yshown inthe drawing, the cast door is relatively thick and the "i5 edges are beveled toward the outer surface to present a surface of minimumy leverage for a tool which might be inserted between the adjacent edges of the door and the receptacle. j e SQ j In accordance with this invention the lock supporting member 13 is formed o-f strip steel orl other suitable metal bent into a U- shaped structure having angular portions 15 which are embedded in the cast door 12. 8JV

having reinforcing end portions 17 and 18 90 projecting out from the rear surface of the door. As shown in Fig. l the L-shaped lugs 16 and the reinforcing ends 17 and 18 of the plates 14 engage the inner surface of the rim '11 on the receptacle 10 and the 95 inner surface of the door 12 adjacent the lower end engages the outer surface of the rim 11 on the' receptacle.

A. unitary structure is thereby provided andthe weaknesses of a door with members 00 welded, riveted, avoided.

The cast manganese steel door offers a strong closure for the cash receptacle of the telephone set and it is very difficult to obtain access to the interior by the use of drills or prying implements. It will be seen that the losses occasioned by unscrupulous persons breaking into the coin boXes will be stopped and this destructive practice discouraged. Furthermore, the improved door offers reduction in the cost of manufacture, since the number of operations for assembling the door is reduced to a minimum.

What is claimed is;

l. A coin receptacle comprising a compartmenthaving an opening therein, a cast steel door for closing said opening,a plurality of lugs of strip steel, each of said lugs having aflat portion rigidly held between the outer and inner layers of said door and another portion projecting through the inner' or screwed thereto are layer for engaging the inside of the comhv partment at the edge of the opening therein.

2. A coin receptacle `comprising a compartment having an openingtherein, a cast steelV cover for closing said opening, a U- shaped strip steel member having oppositely projecting arms rigidly held between the outer and inner layers ofsaid cover, said U-shaped member lprojecting through the inner layer of saidcover, a lock supported on said member and a lug of strip steel having a flat portion rigidly held between the oute'rand inner layers of saidcover and another portion projecting through the inner layer, said lock and said projecting portion of the lugbeing adapted to engage the inside of the compartment at the edge of the opening.

3. In a coin receptacle, a casing having an opening therein, a cover therefor comprising a cast steel plate for closing said opening, and a supporting lug of strip steel having a flat U-shaped portion embedded in the material of said plate and extending parallel to the surface thereof, said flat portion having upturned outer edges projecting through the surface of said plate, the lower edge having a part extending parallel to the surface of said plate for engaging the edge of said opening.

4i. A coin receptacle comprising a coinpartment having an opening therein, a cast steel door forvclosing said opening and a supporting member of sheet steel having a flat portion permanently embedded in said door between the inner and outer surfaces thereof and two substantially parallel upturned portions projecting through the inner surface of said door, said projecting portions being longitudinally extended beyond the embedded portion and adapted to engage the inner edge of said opening.

A coin receptacle comprising a compartment having an opening therein, a cast `steel door for closing said opening and a supporting member 0f sheet steel having a fiat portion permanently embedded in said door between the inner and outer surfaces thereof, and three upturned edges projecting through the inner surface of said door and adapted to engage the inner edge of said opening, two of said edges being substantially parallel and the third extending between them.
