COIN-PROPELLING DEVICE Application filed June 5,

This invention relates to coin-propelling devices for coin-controlled vending ma lune-.1.

The object of the invention is to provide a device which will receive a coin of predetermined size, weight and composition, and

no other, and propel it across a gap.

A further object ofthe invention is to provide means for discharging any coin of'a size smaller than that desired, so that it does not enter the coin-controlled mechanism,

The invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part hereof, is illustrated a form of embodiment of the invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a vertical section through a casing, showing the application of the invention in side elevation;'-

Figure 2 is a vertical section through a casing, showing the application of the invention in rear elevation; 1 I

Fi ure 3 is a vertical section, taken from the front to the rear of the device, and centrally thereof, the coin to be used being shown in its position as it is about to enter the device; and

Figure 4 is a fragmentary detail in vertical section, similar to the left hand end of Flg ure 3, the coin being shown in its second posltion, about to be propelled across the gap be tween the point of insertion and the chute.

Referring to the drawings, 1 designates a casing having the usual slot or opening 2 n one wall thereof.

Disposed over theopening 2 is the usual form of plate 3 having a coin slot 4 therein, adapted to admit the passage of a coin 5.

Dis osed so as to register with the slot 4 there IS arranged a pair of vertical plates 6, which may be secured to the plate 3 or to the wall of the casing 1. These plates for additional ri idity and for spacing are secured together a jacent one corner by meansfof a rivet 6. The plates 6 are arranged so that the space between'the same registers with the slot 4.

The plates 6 are secured together by means of an upper rod 7 which is fixed with relation to the plates and disposed "on the rod 7 is a friction reducing member 8, preferably simply a washer disposed on the rod 7 be- 55 tween the plates 6.

The plates 6 are further secured together son VENDING MACHINES.

1925. Serial No. 35,237.

by means of a lower rod 9 fixed with relation to the plates and arranged to carry a friction reducing member 10 similar tothe washer 8.

A U-shaped member .11 is provided with upturned ends 12 and arranged beneath the loweredges of the plates 6 and maintained in one positon and b means of springs 13, secured at their lower ends to the upturned ends 12 and secured at their upper ends-to any convenient adjacent part.

The lower edges of the plates 6 are slotted to receive the ends of transverse rods 14 which are carried by the upturned ends 12 of theiU-shaped member 11 and suitable friction reducing members 15 are disposed on the rods14 between the plates 6. Normally the rod 9 and the rods 14 occupy thesame vertical plane. However, when the coin 5 is inserted and falls downward by the pressure of the upper rod 7, the rods 14 are forced downward, against the tension of the spring 13, to the position shown in Figure 4.

' A partition or wall 16 is secured to the plate 3 and extends rearwardly of the casmg 1. A magnet 17 is carried by the partition 16 so that if a slug or imitation coin of base metal is inserted, it will be attracted by the magnet and withdrawn from its ordiiary path of movement.

A chute 18 is carried by the rear end of the partition 16 and its upper end is arranged in vertical alinement with the slot 4 and the opening between the plates ,6, and

its upper end is also arranged higher than the slot 4 so that the coin 5 will pursue an arcuate path when inserted and operated upon by the friction reducing members 8, 10 and 15. The tension of the springs 13 1s proportioned to the weight of the coin ofpredetermined size to be used in the dev ce.

Secured to or carriedby the chute 18 is a downwardly projectin grooved way 19, the lower end 20of w ich is ofiset and curved away from the vertical plane-of the slot 4 ahd chute 18. This permits a coin The tension of the spring 13 is thereby,

to the second position shown in Figure 3.

If the coin is of the diameter redetermined, it follows down the groove way 19 into the coin box 21. If the coin is of the proper size but is of base metal, afiected by magnetism, the magnet 17 attracts it out of its proper path so that it either sticks to the side of the wall, or is deflected so thatit does not enter the chute 18. If the coin is of less diameter than the Width of the way 19 it drops through and does not follow the tortuous passage of the Way and therefore does not enter the box 21.

Having thus fully described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. A coin-controlled device comprising a slotted plate, disposed adjacent thereto and registering therewith, an upper fixed friction reducing member carried between the plates, a lower fixed friction reducing member carried between the plates, a pair ofmovable frictiona pair of vertical members.

reducing members carried between the plates intermediate of the slotted plate and the lower fixed friction-reducing member and a chute disposed in alinement with and at a point removed from the slotted plate.

2. A coin-operating device comprising a slotted plate, a pair of vertical members disposed adjacent thereto, an upper fixed friction-reducing member carried between the plates, a lower fixed friction-reducing member carried between the plates, a pair of movable spring-retained friction-reducing members carried between the plates intermediate of the slotted plate and the lower fixed friction-reducing member and a chute disposed in alinement with and at a pointremoved from the slotted plate.

3. A coin operating device comprising an insertion element, fixed friction reducing means and resiliently supported friction reducin means disposed adjacent the insertion e ement and a chute in alinement with and at a point removed from the insertion element.
