CHARLES J. PAULSON, OF BROOKLYN, NEW YORK, ASSIGNOR OF- ONE-THIRD TO MATTHEW v. o'mLLEY, or BROOKLYN, New YORK;

COIN-SELECTIN G MECHANISM.

Application flied February 4, 1926, Serial No. 8,685. Renewed May 19, 1928.

This invention relates to selective mechanism for the delivery of designated coins,

coin guide hung upon an inclined frame.

capable of being swung and displaced by the action of a coin or other device passingthrough the coin slot; also a weighted shield that is hung upon lugs extended from the guide, which shield closes against the guide to retain the coins or spurious coins'laterally in their passage, but said shield bein g adapted to become separated from the guide to permit rejection of a spurious coin when another coin is entered through the slot;

form of a magnet, to engage magnetically the disks, said device having one longer arm that projects from the frame into the path of the coins and spurious coins, said device having a shorter arm which impales a washer whose weight is imposed on the longer arm; also a guide channel to direct true coins along a predetermined path when the weight of such coins is imposed upon the longer arm of the pivoted device to depress it.

Other features and advantages of my invention will hereinafter appear.

- In the drawing:

Figure 1 is a front elevation of my improved mechanism, including a part of the frame on which it is mounted and a portion of an enclosing coin box including the slot therein.

Fig. 2 is a side view thereof, the frame appearing in section, dotted lines showing the swung-back positions of the coin guide and shield under the influence of an entered com.

Fi 3 is a similar view of the guide and shiel in their normal positions.

also an eccentrically pivoted device in the' v p the path of a'coin entered therethrough, so

the lower part? of 1 the Fig. 4 is a side view thereof.

Fig. 5 is a front view of the shield.

Fig. 5" is a side view thereof, and

Fig. .6 is a detail side view of the eccentrically pivoted device, in the form of a magnet, which serves to reject all kinds of spurious coins and permits the free passage of true or designated coins only.

In the representation of my invention herein illustrated let 1 indicate a frame upon which the mechanism is mounted, 2 an element composed of sheet material which I call the coin 'guide, 3 another element which I call the shield, and 4 that part of a coin box having the coin receiving slot 5. The frame 1 is disposed in an inclined position 'b'eneath the slot 5. Said frame has a rounded edge 6 to support, the guide 2 by means" of lugs *7 that extend rearwardly from said guide and have curved engagi ng surfaces8, wherebysaid guide may be "swung, using said frame edge 6 as a fulcrum. -The upper end of guide 2 is pro- 7 'vided' with .an inclined nose-piece 9,"that extends up nearly to the slot 5 to be in that a passingcoin will fall upon the incline of said nose;- iece 9, and by;its weight, so or with theadditionof pressure will cause the upper 'partof the guide to..swing rearwardly upon its' fulcrnm,-thusalso causing 'ide to swing forwardly. The coin having displaced nose- 86 piece 9 will'slide down the guideagainst the forward surface thereof, said guide, due

to the preponderance .ofiit safweightbelow the .fulcrum swin ing baol tto. its normal position against t e frame, The guide is 90 provided with sidewalls having. suitable curvatures which direct the, ath of the coin. Thus there is .a curved wa 1 portion -10 at one side that deflects the coin-to the opposite side, where it meets a curved wall portion 11 that deflects it back to a curved wall (portion 12, these deflections tending to retar the speed of descent, and the curved wall portion 12.-guiding the coinlaterally toward an opposite, downwardly curved wall portion 13, which .continues into a downwardly directed exit for the delivery of the coin into an opposed passage, chute or receptacle 14. It is the purpose of my invention that true or designated coins shall take the course described, In their passage along the guide however, said coins will alight upon an arm 15 of a plate or body 16 which is pivoted at 17 to a lug 18 extended rearwardly from frame 1, said body having another, shorter arm 19 and constituting a magnet of which the arms 15, 19 are the respective poles. The pivot 17 is so located, at the lower part of body 16, that the arms tend to swing upwardly, but are held horizontal by reason of arm 15 engaging the lower edge of frame 1, said arm 15 being extended forwardly in advance of the front surface of the frame. The arm 19, which is shorter is entered into a slot 20 through the frame, its end being normally flush with the forward surface of the coin guide, which is slotted at 2 to receive it, but capable of projecting beyond said surface if the device be rock-ed upon its pivot.

When a true or designated coin passes in the manner already described along the guide, and alights upon arm 15, the weight of such coin depresses arm 15, rocking the device upon pivot 17, and the degree of that depression is sufficient to provide a clearance between arm 15 and wall portion 13 to permit the coin to pass; whereas if the arm were held rigid the coin would become wedged between it and wall portion 13. This 15 what occurs to a disk or light weight coin that fails to depress arm 15.

It-will be noted that the u er part of shield 3 is provided with si e lugs 21, adapted to engage in bearing slots 22 formed in brackets 23 that project forwardly from guide 2; also that shield 3 has a curved lower portion 23 that lies over the laterally fxtended portion of the coin guide-way, said ower norma y hold assing coins and spurious coins against t e guide. When, however,

the uide is swung upon its fulcrum, as by t e previously described act in introducin a coin through slot 5, the shield is sprea :1 art from the guide by reason of rearwar y projecting lugs 25 on the shield which en age the frame 1 as the top part of the shiel swings backwardly.

In the tilting of guide 2 and the spreading apart action of shield 3 a lightweight disk or spurious coin that may have become lodged upon arm 15, thus being removed disk,

ortion being weighted, as at 24, to-

a magnet will attract and hold a magnetizable disk that reaches the arm 15, preventing it from following further along the path of a true coin, and such magnetizable disk will be ejected by tilting action of the guide.

It must be appreciated that coincident with the tilting and ejection action of guide 2, shield 3 is spread apart therefrom to facilitate the get-away of the ejected spurious coin, disk or washer.

Limiting means to the extent of the guide tilting and shield spacing movements are provided in the form of a lug 26 extended from the guide wall 12, in parallelism with the guide surface, said lug serving as a stop to engage the shield, which in turn prevents further forward movement of the shield.

In Fig. 2 I have shown a true coin 27 as falling through the chute 14, and a spuri- I ous coin 28 as ejected to be guided by wall 29 into a receptacle therefor.

Also I have shown a spurious coin 30 lodged upon arm 15.

As a washer the spurious coin appears impaled upon the rojected arm 19, and if a magnetizable dis t, then it is held by the poles 15 and 19 of the magnet.

Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.

I claim.
