SPECIFICATION forming part of Letters Patent N o. 641,496, dated January 16, 1900.

Application filed March 10, 1899. Serial No. 708,587. (No model.)

To @ZZ whom t may concern:

Be it known that I, CHARLES BUSCH, technologist, of 30 Rue Berger, Paris, in the Republic of France, have invented certain new and useful Improvements in Sorting Apparatus, of which the following is a specication.

My invention relates to an improved apparatus by which I am able, without any mechanism,to sort round or nearly-round objectssuch, for example, asV pieces of money.

My apparatus is illustrated -in the accompanying drawings, in which- Figure I is a section on the section-line shown in Fig. 2. Fig. 2 is a v-section on the section-line shown in Fig. l. Fig. 3 is aplan view, the top cover being omitted. Fig. 4is a side View of the front wall ofthe sorterpassage. Fig. 5 is a like viewof the rear wall of said passage. Figs. 6 and 7 are vertical transverse sections of two front walls of an old form of passage. Fig. 8is a like view of my improved passage with front and rear walls and transversely-curved bottom.

I provide a passage or channel Z, curved or inclined longitudinally, as shown in Fig. l, and also inclined transversely, as shown in Figs. 2 and 8. The channel has an inlet j large enough to admit the largest objects to be sorted. Preferably the channel is made of a front or under inclined wall b and a rear or upper wall c, having lugs f, by means of which the sides are secured to the top g of box o just below the cover. In Figs. 4 and 5 lugs f are shown before being bent at right angles to the channel sides. Walls h c are parallel with each other, and wall b has an opening increasing in Width, preferably by distinct steps differing in height in accordance with the different sizes or diameter of the objects to be sorted, as indicated at c c2 e3 e4 c5 c6 c7. This opening does not extend quite to the bottom of side b, but leaves a narrow iiange b', which forms one side of the transversely-curved bottom or gutter in which the objects to be sorted roll. Longitudinally the gutter curves or inclines downward from inlet j. Preferably the pitch is greatest near the inlet end, as between and y, and diminishes between y and z, so that the larger objects will not descend too rapidly, but the objects will issue at about the same speed from all of the parts of the openings e e2, doc.

Wall c has a opening d extending nearly the length of the opening in wall b.

By cutting away the rear wall forming opening d, extending downward to the center of the gutter, the coinsrwill be free to fall through openings e', doc., without danger of being caught in a manner similar to that shown in Fig. 7, as they might be were opening d not provided. In Figs. 6 and 7 wall b is shown extended and bent to forma rectangular inclined bottom or gutter of the channel as heretofore used.

It will be seen that with gutters having the form of bottom shown in Figs. 6 and 7 there is danger, if the gutter be too wide, of the coins or objects rolling down takingtoo great an inclination, as in Fig. 6, and dropping out through the side opening where it is of less width than that intended for the coins to issue from. On the other hand, if the gutter be a triiie too narrow in said old form, as in-v dicated in Fig. 7, the coin may be caught and held, as shown. My transversely-curved gut- 'ter compels the coin to take a slightly-inobjects sorted. The distance between the center of the tread or bottom of the gutter and the upper stepped edge of the opening in wall b at any point should equal the diameter of the coin intended to issue at that point plus a triiie suflicient to allow the coins to tip. I have shown the opening in wall b as continuous, the upper edge being stepped; but it is not essential that the open parts of different heights communicate with each other.

In box o is a drawer h, divided into two rows of compartments t" t2 i4 716 and i3 5 117. In order to be able to use larger compartments than would otherwise be practicable, alternate openings e' c3 c5 e7 communicate with the compartments of one row, and openings e264 IOO 2 eifle e communicate by chutes k' 7a2 7c3 with the compartments of the other row.

I claiml. 1n a sorting apparatus, a longitudinally and transversely inclined channel having a transversely-curved bottom along which objects to be sorted roll and an under Wall b having an opening increasing in Width from the inlet end, through Which objects fall at points of corresponding Width.

2. In a sorting apparatus, a longitudinally and transversely'inclined channel having a transversely-curved bottom along which objects to be sorted roll and an under Wall b having an opening increasing in Width by steps from the inlet end, through which objects fall at points of corresponding width, in combination with several separate compa-1t ments in two rows, the sections or steps of the openingin Wall b communicating alternately with compartments of said rows.

8. A longitudinally and transversely in# clined chute or channel for sortingapparatus having a quick descent near the inlet end and a decreasing descent or inclination toward the lower end, havinga transversely-curved bottom, the under Wall b of the channel having an opening of comparatively small Width near the inlet end and increasing in width toward the other end.

4. A chute or channel for sorting apparatus having in combination a Wall Z7 With opening of increasing Width and a Wall c with opening CZ opposite the opening in Wall b, said Walls together forming a transversely-curved bottom or gutter.

Signed at Paris, France, this 28th day of February, 1899.
