Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed December 3, 1912. Serial No. 734,792.

To all whom it may concern: Be it known that I, Or'ro GAMPER, a citizen of the Republic of Switzerland, residing at Zurich, Switzerland, have invented new and useful Improvements in Machines for Facilitating the Packing of Magnetic Objects of Oblong Shape; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

In my Patent 1,014,869 of January 16th, 1912, I have described a machine for facilitating the packin of magnetic objects of oblong shape, in w ich machine magnets are arranged at a distance corresponding to the length of the objects, which magnets have their opposite poles directed toward each other. The magnets form a groove between them and a feeding device causes the objects to pass between the magnet poles and while the objects are being placed parallel by the magnetic attraction of the poles, they are moved forward by the carrier. The objects placed parallel in this manner during the moving may beremoved by hand from the feeding device and packed in boxes. This can only easily be done when the objects are of such length that they can be seized by the whole hand. For short objects where the magnetic poles are arranged at only a small distance from each other, so that one cannot get in'by the whole hand but only by one or two fingers, this device is not so handy. In this case the filling of the short objects in a packing receptacle would be difficult. There as also beenrproposed a device in which there is provi ed a vertical groove which is closed at four sides. In this device the direction of filling coincides of course with the longitudinal direction of the groove. Because the fillin opening has only a small cross-section this machine works only very slowly. The vertical groove renders a control impossible and causes obstruction.

By the device according to this invention these drawbacks are overcome thereby, that a horizontal stationary groove or canal is formed between unlike poles of a stationary magnet the feeding being performed at the same time on the whole length of the groove and the emptying of the groove being performed transverse to the direction of filling 111 a packing receptacle after. the compression of the objects in the groove.

In the drawings an example of the machine fcrming the subject matter of this invention is shown.

Figure 1 is a side elevation of the same partly in section. Fig. 2 is a vertical section on line 11-43 of Fig. 1. .Fig. 3 is a plan view of the same. Figs. 4 and 5 are detail views.

A shaft 21 which is impelled by a motor not shown in the drawing continually rotates and therewith rotates an eccentric 16, on which there rests by means of yielding plates 11 a rocking plate 14 which is arranged at the front side of a receptacle 15. The plates 11 are yieldingly mounted on oscillating

bars

12 and 13 so that the whole receptacle 15 can rock therewith. Below the front side of the rocking plate 14 a roove or canal is formed by two feedin p ates 4 and 5 of non-magnetic material, t e plate 4 being secured to the leg 1 and the plate 5 to the leg 3 of a horse-shoe magnet. The magnet is excited by a magnet coil 18. The leg 3 is movable on a support 2 by means of a. screw 7 so that the distance of both legs can be adjusted. Between both legs 1 and 3 a shallow trough 6 is mounted to turn about a hinge 22 and may be exchanged. A beater 19 is mounted to turn about the same hinge in the direction of the arrow (Fig. 1) and the beater is held in vertical direction by a sprin 19". The trough 6 rests on a strong spring 6? and is held by it in horizontal position between the

legs

1 and 3 of the horseshoe magnet. A foot lever 8 o crates first-1y a switch 9 insertedin the circuit of the magnet eoil 18, which switch is opened by moving the foot lever downward, and secondly a pusher rod 10 which is raised by moving the foot-lever downward, whereby the rocking plate is lifted from the eccentric 16, so that the feeding is stopped. At the same time a plate 17 is raised, which is arranged above, thefeeding plate. By this means the )late 17 is moved in the path of the objects in ling down from the rocking plate.

The machine operates as follows: If the foot lever is in its upper position the switch 9 is cut in and the horse-shoe magnet is excited, so that there is a stron magnetic field between the

legs

1 and 3. The rocking plate 14 is rocked by the eccentric 16, so

that nails in the receptacle 15 slide on the rocking plate. and singly" fall between the feeding plates 4;, 5, where they move in the magnetic field so that by moving farther down they move parallel into the trough 6. After the trough is filled and the roove between the feeding plates partly fille with loose parallel nails the foot lever is moved downward, the switch 9 is opened and the exciting of the horse-shoe magnet is stopped and the nails in the groove will sink into the trough. At the same time the rocking plate 14 is lifted from the eccentric 16 so that the feeding is stopped and the plate 17 is turned in the path of the nails falling in the groove, so that they are prevented from moving farther downward. Then the beater 19 is moved downward against the force of the spring in the direction of the arrow (Fig. 1) and the nails are closely pressed thereby. cated in dotted lines, Fig. 1 is moved onto the free end of the trough 6, the latter is moved downward and the nails placed parallel are suddenly delivered in the packing box which is wholly moved on the trough. After the trough is emptied it moves automatically upward between the legs of the magnets and is read for use again. In this manner it is possi ].e to place the smallest magnetic obj ects of oblong shape parallel and to fill them in packages.

Since the objects can. be seen while they are placed parallel, the objects which would cause trouble in other devices, (for example waste of wire, nails which are longer than those to be packed, and the like) can be re moved by hand without stopping the feedmg.

By a machine according to this invention there may also be separated nails of difl'er-.

ent lengths by correspondingly cons ructing the groove between the two legs of the magnet. For separating nails of two different lengths the described machine may be used without any change, by adjusting the groove Hereafter a packing box 20 indi-- to the length of the short nails. I'he long nails remain on the mouth, where they may be removed by hand. f

I claim:

1. In a device for facilitating the packing of slender magnetic objects of oblong shape, a horse-shoe electro-magnet, a canal of U- shaped cross-section arranged between the legs of the electro-magnet, and feeding means arranged abovethe open longitudinal side-of said canal adapted to distribute the objects to be packed over the whole length of said canal.

2. In a device for facilitating the packing of slender magnetic objects of oblong shape,

a horse-shoe electro-magnet, the legs of said magnet being adjustable to different distances from each other and forming a horizontally arranged groove, a hinged bottom member provided with a free end adapted to receive a packing box, and feeding means arranged above the open longitudinal side of said groove adapted to distribute simultaneously the objects to be packed over the whole length of said groove.

3. In a device for facilitating the packing of slender magnetic objects of oblong shape, a horse-shoe electro-magnet forming a horizontally arranged groove, a shallow trough hinged below the groove provided With a free'end adapted to receive a packing box,

into which the -trough is emptied in the transverse direction of the feed, feeding means arranged above-the open longitudinal side of said groove adapted to distribute simultaneously the objects over the whole length of said groove, and a device adapted to interrupt the current exciting the magnet and stop the feeding simultaneously.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

OTTO GAMPER.
