6 Claims. (Cl. 1941-99)
This invention relates to a coin selector for telephones,
dispensing machines, and similar devices, and has for
an object to provide a simple and effective device which
will separate good coins of the denominations of ten
cents, five cents and twenty~iive cents from spurious
or bad coins, or Aso-called slugs.
It is also an object to provide a device of this char
acter which will distinguish ybetween a-nd separate these
coins of different sizes and values and discharge them
through separate exits from the device for operating

of spurious or bad coins, s'uch, for example, as coins of 20 comprising a ten-cent piece or so-ca-lled dime, a iive

Another object is to provide a construction of this
character in which the good coins of the three diiferent
sizes and values are separated from each other and the
spurious coins or' so-called slugs by rolling action only
of the coins along runways past various selecting devices.
‘Still another object is to provide a device of this char
acter capable of separating the three coins of diiïerent
sizes and values from each other and from spurious coins
or slugs, which is devoid of bouncing anvils and pivoted
deflectors or similar coin separating devices, so that the
coins have a rolling motion only and the forward motion
of the coins is controlled in the runways so that the
velocity of the coins as they pass selecting devices along
the various runways will attain a speed in accordance
with that required for proper selec-tion.
Still another object is to provide a device of this char
acter which is of very simple construction and will oc

location in any machine or device to be controlled, such,
for example, as a dispensing mechanism Ifor various arti-y

coin-controlled devices, the good coins of diiferent sizes
35 and values being conducted or directed by any suit-able
means (not shown) to the respective mechanisms to be
controlled or released, and the bad or spurious coins
or slugs being kept from the controlled mechanism or
devices and directed to any suitable container or eject

The device illustrated comprises an upright main or
intermediate plate 1 having three openings 2, 3 and 4
therethrough, which openings are of diiferent sizes, as
shown in FIGS. 1 and 5, to accommodate the three coins

cupy a minimum of space, so that it can be manufac
tured at relatively low cost and will not require a large
space in the machine in which it is employed.
A still further object is to provide a device of this
character in which there is no mechanism to be operated 50
or shifted as a coin is inserted in the device to thus
of different diameters, ten-cent, tive-cent and twenty-live
cent pieces, and these three openings are arranged in
succession, as shown in FIGS. 'l and 5, from -a coin
inlet opening 5 at the top and one edge of the machine.
This opening 5 may be flared as shown to facilitate inser

member 5a embracing the top edges of plates 1 and 6.
A front plate 6 is secured to the forward side of the main
