NAIL-SORTING DEVICE.

Application filed March 1, 1926. Serial No. 91,555.

The present invention relates to improvements in nail sorting devices and consists.

'.lt isv an object ot the presentinvention to.

improve the construction of the trays or sorting sieves as described iu the above referred to applications to the end that a more expeditious and faithful sorting of the nails may be secured. f

lt is another object ol2 the invention to provide a device which will be compact and which by reason of the incorporation ol moving sorting parts therein, will greatly increase the capacity of present devices. I

lVith the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols referto like orcorresponding parts throughout the several views,

Figure 1 is a vertical section taken centrally through an improved nail sorting device constructed according to the present invention;

Figure 2 is a top plan view thereof;

Figure 3 is a fragmentary vertical crosssection through the same taken at right angles to Figure 1.

Referring irst to Figures 1, 2 and 3, 8 designates an appropriate framework or base upon which vertical longitudinal spaced walls 9 and 10 are erected. These walls are mounted in pairs and are spaced from each other and also from adjacent pairs of walls. The space between the walls 9 and 10 is greater than the space between the pairs of walls. VThe space between the walls 9 and 10 is covered at the upper portion by covering strips 11 of substantially triangular form having upper pressed portions and divergently sloping walls therefrom which direct the nails thrown upon the device toward the slots 12 and into the spaces between the pairs of walls 9 and 10. ln these spaces are arranged belts in 1 `any suitable number, the belts being superposed. one above the other. In the instance shown, three supersposed sets of belts are shown and these belts extend about drive down between the belts.

pulleys 13. 14 and 157 mounted [upon the Y drive shaftsv 16. These drive shafts. are erected in the space between the walls 9 and l0 and extend below thebase 8where they are provided with the gear whee`s17 'and a suitable source of power.v The various belts are indicated at 119, 2O and21, and they are preferably otditl'erent lengths as shown in Figure 1. `Here the lowermost belt incsh with power gear wheels lidrivenffrom 1 is the shortest belt and the belts arev graduated in length 'from the lowern'iost tothe upi'ierniost belt. which latter is thelongest. The graduated ends of the belts extend around Jthe puleys 22, 23k and 24 mounted upon the shafts 25, 26 and 27, respectively, and such `graduated ends of the belts are arranged to deliver the nails to separate . chutes 23, 29 and 30. These chutes mayl carry the nails to appropriate bins or rey ceptacles. v i 4 rlhe walls 9 and 10 are provided withl ledges 31,32 and 33 extending into the sort ing space tor catching the adjoining runs of the belts and supporting the same during the time these belts carry the nails. The belts are driven in the direction of the arrows indicated in Figure 2 and the upper edges of each 0f the belts are enlarged and formed with the inwardly projecting lips 34 and with the upwardly slopingsurfaces above the lips. These lips project inwardly with reference to the slot through which the nails drop onto the belts. It will be seen from Figure 3 that the lowermost belts 19 are disposed closest together as to their runs in the nail slot. The next higher belts 20 are spaced slightly wider apart to receive nail heads or' slightly greater diameter and to preventkthem from falling through to the lowerlnost belts. v The heads of the nails are caughtv upon the upper beadedl or headed "edges of the belts and the heads will lie upon the upper sloping surface ot these'beaded edges, while the shanks of the nails will drop The nails will be carried along by the belts toward the chutes 28, 29 0r 30. l The uppermost belts 21 are located wider apart in the nail slots in order to receive only the largest nails fed into the device.

`Ot course, it will be understood that two or more belts may be used and that the belts may be mounted and driven in lany appro# priate manner. The device shown is ap` propriate for sorting by Vhead nails of three diiferent sizes,-for instance, three penny connnon, three penny line, and three penny extra ine. The belts will carry the nails along and effectively prevent clogging` of the device.

The beaded edge or projection at the tops of the belts may not be necessary in hen-v d'ling small sizes ot nails, say up to live penny.

It isobvious that various changes and modiications muy be mede in the details oi construction and design o't the above speciiically described embodiment ot ythis invention without departing 'troni the spirit thereof, such changes andmodifications being` re` etricted only by the sficope'oli the :following claims.
