To all 'whom t may concern Be it known that I, FREDERICK L. SATTLEY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Coin-Sorter's, of which the following is a specification.

In the separation of coins into different denominations some difficulty is ei'iperienced ,f because of the tendency of the coms to ride upon one another so that the small coins are prevented from being separated from the larger coins.

-The object of my invention is to produce a coin-sorting apparatus in which riding coins will be forced 0E from the carrying coins.

More particularly the object of my invention is to produce a sorting structure comprising a plurality of substantially horizontal, or slightly inclined superimposed differentially perforated shelves which will serve to permit small coins to pass therethrough, and provided with means fo engaging the coins in such manner as to i terrupt them and insure an overriding motion of any coins which may be carried by and be riding upon the interrupted coins.

A further object of my invention is to provide the eceiving'shelf for the smallest coins with feeding; ridges which willA insure their propervmovement to the discharging outlet.

A further object of my invention is to provide means for eliminating the noise which is ordinarily an accompaniment of a sorting mechanism of this classand to provide such other changes in details of construction as may hereinafter be pointed out. The accompanying drawings illustrate my invention as applied to a sorter of the vibratory type, as distinguished from the gyratory type, but it is to be understood that my invention is equally applicable, to other types of sorters.

Figure 1 is a plan of an apparatus em- `bodying my improvements; Fig. 2 a side elevation of the parts shown in Fig. 1 and including also a mechanism for vibrating the structure; Fig. 3 an elevation of the discharge end; Fig. 4 a section on line 4 4 of Fig. 3 on an enlarged scale and Fig. 5 a sectional detail showing the coin interrupting and the sound deadening members in conjunction with a perforated shelf.

In the drawings'lO, 1l, 12, 13 and 14 indicate a plurality of superposed differentially perforated shelves combined into a single vibratory structure in a well known-manner, said shelves being preferably formed of comparatively thin sheet metal. The shelves deliver to discharge spouts 10', 11', 12', 13 60 and 14 respectively and below the shelf 14 is arranged. an imperforate -plate or shelf 15 which delivers to a discharge spout 15. Vith such a construction the noise made by the coins dropping through the partitions is quite objectionable and I have found that, by placing beneath each partition a sound absorbing plate 16 perforated to correspond with the plate which it supports, I am able to practically eliminate the noise. In prac- -tice I make the plate 16 of heavy cardboard to materially strengthen and support the metal plates or shelves.

It. is necessary t0 keep the metal plate in close contact with the deadening plate and I therefore provide a plurality of bolts v17 which pass through the metal plate and its supporting deadening plate 16 and clamp the same firmly together. I then provide'some or all of the bolts 17 80 with heads 18 which are preferablycylindrical so as to have a surface which will lie substantially' at right angles to theworking face of the sorting shelf and this head projects above the working face of the sorting shelf anamount slightly less than the thickness of the coin which is to be retained upon the shelf. This leaves a considerable range for the amount of projection of the h'ead between that permissible for a dollar shelf and that required for a penny shelf but in practice I find it sufficient if all of thm heads project from their shelves an amount?l slight-ly less Ithan the thickness of a copper p'enn'y, z'. e. slightly less than the thickness 95 of the next to the smallest diameter of coin.

`Shelf 15 has its. upper or receiving face formed into a plurality of teethor ridges 21 having their shoulders 22 presented toward the discharge chute 15 so as to force the 100 coins to travel toward the discharge chute in a well known manner.

In operation a conglomerate stream orA mass of coins is delivered to Ithe receiving face of the uppermost shelf 10 and many 105 coins will ride upon other coins soV that, when the carrying coin is larger than the carried coin, the carried coin would .be prevented from passing down through the perforations 10 to the shelf 11. vibrated, however, the 'coins will be-driven' along the faceofshelf 10 and will come into'v As the structure is contact with the projecting heads 18 of pins 17 so that if any coins .be riding upon the interrupted coins the riding coins Will be shot oft' from theinterrupted coins and will pass freelyl over the projecting heads 18, so as to come down upon the shelf and, 1f small enough, will pass freely through the perfo- .rations to the next shelf below.

'shelf between the perforations thereof and having a projecting extent less than the thickness of coins Which will not pass through the perforations of the shelf. j

2. In a coin sorter, a series of superimposed diflerentially perforated sorting shelves having openings through which the coins are projected in the sorting operation, and obstructions situated in the path of travel ,of the coins with relation to I[hel shelves, said obstructions being elevated above the adjacent shelf to a height approximately no greater than the thickness of a coin properly lodged on that shelf, whereby such coins Will not serve as carriers to prevent smaller coins 'from passing through the perforations of such shelf.

3. In a coin sorter, a series of superimposed dierentially perforated shelves having openings through which the coins are projected in the sorting operation, and obstructions situated in the path lof travel .of the coins With relation to thev shelves, said obstructions bearing such relasorting' tion to an adjacent shelf as to prevent.

smaller coins from permanently riding upon those coins intended to be retained by such shelf.

In witness whereof, I, have 4hereunto set my handand seal at Indianapolis, Indiana. this thirtieth day of October, A. D. one thousand nine hundred and nine.
