NAIL-SORTING DEVICE.

Original application filed October 9,1924, Seria1'No. 742..-85.7. Divided-and this application filcd January, i 17,1926L seriai'na 79;:356. v

The present. inventionrelates to improvements in nail. sorting devices, and the. present application is a'division of my prior copending and :similarly entitled, application filed October 9, 1924-, SerialQNo. 742,657, PatentNo. 1,592,697, patented July 13, 1926. a 1 The-invention forming the subject-matter of this divisional application has in. common the same objects. as those described in the parentcase, abovereferred to,.and addition-- ally aimstoprovide an improved sieve or tray for theyefiicient separation of the nails or like articles, said tray to be usedin con junction with the drum forming the subjectmatter of the parent case.

With the foregoing and other objects in 1 view, the invention will be'j'more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer tolike or corresponding parts throughout the several views. V Figure l is a fragmentary elevationof a nail sorting drum shown above several sieves illustrated in vertical section, certain of the sieves being broken away,

Figure 2' is a plan view of one of the sieves,

Figure 3 'is a fragmentary perspective view, showing a portion ofthe sieve construction, and V Figure 4; i enlarged scale ofa portion of the sieve.

Referring more particularly to the drawings, the drum designated at 11 is of the construction more particularly shown, described and claimed in my co-pending application aforesaid. The iperipheralplates at one side of the drum are indicated at 13 and theseare spaced apart to permit the passage of the nails to the several'sieves below the drum which is disposed with its axis at an inclination to the horizontal. The base plates of the drum are indicated at '15, and the'partitions at 16. These partitions are grouped together more closely at one end of the drum and the distance nails of different lengths maybe liberated from the drum at certain designated sections of the drum beneath which are placed indi vidnal sieves to catch and further sort such 1 nails.

s a cross-sectionv taken on an These sievesfare oomposedof metal mem bers as fshowni'j in Figures 3 and. fl, these: metal members, paralleling, one another and in. the members at the sides of. the slots. 'At

'the ends of theslots are openings '36 large enough to: permit the heads35of. the nails to drop through. These openings'3fiwill be of graduated size in. each sieve, or. in

thevarioussievesp. These openings. are pro-u vided in the end plate 37 "held in thefra'me;

ofthe-sieve. The members are nade. upof inverted lJ' -shapedpiece's of sheet metal or channel strips having; the side walls38 and 39 with the open portion of' the channel disposed downwardswhile the upperpart thereof so as to form with the sloping walls a triangular arrangement of great strength.

i is closed by the upwardly convergent walls 40 and ll meeting at. the ridge 42; e The A 'reinforc-g plate 42 is inserted between the walls 38 and 39 preferably at'the upper portions From the bottoms of the side walls 38 and 39 so that the nails will ride down the slots and drop through the openings 36*where openings.

The s1eves may be vibrated byan eccentric the nails are of a size to pass through such 7 I i or. other motion to cause the nails to seek I the openings 36. v a

It is obvious that/various changes and modificationsmay be made in'the details of construction and design of theabove specifically described embodiment of thisinv'ention 1 without departing from the-spirit thereof, such changes and modifications bjeing restricted only by the scope ,of'the following claims. v l

What is'claimed is a the metal isrreturned upon itself outwardly.

and folded into parallel'relation against the f '1. A sieve for sorting nailscomprising a frame having openingsto admit the nail heads, parallel members in said frame spaced apart to provide slots and; said mem here being substantially of channel shape :5

with closed upper sloping walls and side members having spaced side walls forming the slots, and outer walls lying against and reinforcing said side walls, said outer walls extending above the members and said side walls and positioned to receive the undersides of the nail heads to form runways for the latter. A

3. A sieve for sorting nails comprising ad o1n1ng parallel members having slots A therebetween :forfadmitting the shanks of the nails, a frame for holding said members having enlarged perforations at the ends of the slots between'the members for permit ting'the heads of the nails to pass through, said members being made of substantially inverted U-shaped pieces of metal having side walls with upwardly converging and ridged top Walls, and upturned outer Walls along the side walls having their upper free 25 edges at the sides of the slots for receiving the under sides of the nail heads and forming runways therefor.

4. A sieve for sorting nails comprising adjoining parallel members having slots thereb'etween for admittingthe shanks of.

the nails, a frame for holding saidmembers having enlarged perforations at the ends of the slots between the members forpermitting the heads of the nails to pass through, said members being made of substantially in verted U-shaped pieces of metal having side walls with upwardly converging and ridged top walls, upturned outer walls along the side walls having their upper free edges at the sides of the slots for receiving the under side of the nails and forming runways therefor and a reinforcing plate extending between the side walls at substantially the base of the convergent top Walls for forming therewith a substantially triangular structure of great strength.
