ent to O'. F. Forsberg 1,043,219, issued November Fig. 1 is a side view partly in section of the 5, 1912, where it is required that one or more upper part of a telephone coin collector of the coins be deposited for the use of the instrument. type disclosed in the above-mentioned Forsberg Such apparatus usually includes a coin chute patentto which reference may be made for a containing coin channels down which a deposited more complete disclosure.

liable to similar distortion is in that portion of wall I3 opposite slot 23 on which portion the coins may drop with considerable force. Slot 23 in cover plate 8 functions in the same manner as slot I 8 to provide an opening into which the battered metal may go without detriment to the operation of the coin chute. Still a third point in the nickel runway subject to coin battering is that portion of the guide rail near the junction ,of walls I3 and I6 and opposite the slot 24 in cover plate 8. Slot 24 functions in the same manner as slots l8 and 23.

In the preferred embodiment the cover plate 8 is made of sheet steel sufiiciently rigid to prevent any separation of plates 8 and 9 under the action of the metal displaced by the coin battering; and channeled plate 9 is preferably die cast from a soft metal such as a suitable lead alloy.

It is obvious that similar slots may be provided 'in plates forming a part of runways for coins of other denominations such as dimes or quarters to provide an outlet for any metal displaced under the action of deposited coins.

A modification of the invention is disclosed in Fig. 5 and it may be assumed that Fig. 5 is also a sectional view taken along the line 3-3 of Fig. 2.

In Fig. 5, cover plate 25 corresponds to cover plate 8 and channeled plate 26 corresponds to plate 9 with the coin supporting rail 21 corresponding to rail l l. The only difference between Fig. 3 and Fig. 5 is that channneled plate 26 is originally formed with a ledge 28 projecting into slot 29, but slot 29 will function in the same manner as slot l8 of Fig. 3 in that under the action of coin battering, some of the metal from rail 21 will be forced into the slot, thereby forcing ledge 28 farther out through the slot.

What is claimed is:

1. A coin chute comprising a coin channel plate and a cover plate fastened to said channel plate, said channel plate having spaced guide rails extending towards the inner face of said cover plate to define a coin runway between said plates down which a coin will roll or fall under the influence of gravity, said guide rails being formed of relatively soft metal, one section of one of said rails having a coin receiving face which is battered by the relatively hard coins with sufficient force to finally distort said face and the guide rail of which said face is a part, said cover plate having a slot opposite said, face and extending along said face in the direction of coin travel, the upper edge of said slot being located a substantial distance above said face, the distance between said face and the upper edge of said slot being substantially less than the diameter of a standard coin for said runway, said slot extending downwardly from its upper edge a distance at least equal to the distance between said upper edge and said face whereby metal from said battered rail may extrude into said slot.

2. A coin chute in accordance with claim 1 in which said one section of said one guide rail has a ledge projecting into said slot.
