DEVICE FOR AssoRTINe. or MOLDINGS, non INsrA'NcnwoonnN BOARDS: 7

Application filed September 18, 1926, Serial No. 136,381, and in Germany ScptemberM; 1925:v

The inventionrelates to a device, by means of which moldings, as wooden boards for instance, may be assorted according to length, width or thickness and delivered automatically defined placesin accordance with their (llil'lGIlSlOilS., Thedevice in a modified form can also be used to convey moldings. of any. dimensionsto defined places and'deliver them there automatically.

Theaccompanying drawings illustrate the invention, as follows:

Fig. 1 shows a device with hopper-like box, which receives the moldings.

Fig. 2 shows a. box with bottom-flap in closed positiom Fig. 3 shows a box withbottom-flap in opened position.

Fig. 4 shows a device with hopper-like box for delivering a molding of any size at a defined place. 2

According to Fig. l a plurality of suitably arranged hopper-like boxes is provided upon an endless band a running in the direction of the arrow. The walls C in front of the boxes have outlet-slots (Z, through which the revolving moldings 6 may pass. Above the endless band a cam arrangements g 9 g, of different length are provided.

The operation of the device is the following: One molding always is placed into a box in such a way, that it will lie close to the wall 0 in front, so it cannot pass through the slot (Z. During the travel of the band a, each molding of a certain length will hit against a certain cam 9. At first the longest moldings will be engaged by cam g, as shown in Fig. 1; later on the moldings of medium length by cam 9 and finally the shortest moldings by cam 9 In hitting against a cam the moldings will be lifted from the front wall 0 of the box and tilted against the back wall f, of the box, from which slide down through the slot d.

Figs. 2 and 3 illustrate the arrangement of the boxes 6 of suitably constructed longitudiit will 7 'nal shape, which are closed by bottom flaps h and which are kept in closed position under the influence of counter weights, springs or similar devices. The cams g are rigidly connected to the contact-pieces is, which are connected to an electric circuit of electro-magnets Z. The cores m of the latter. will be attracted, when the circuit is closed and moved from the position of Fig. 2 into the position of Fig. 3 into the path'of the counter-weights i. By this means the flaps 71. of: the boxes 6, are opened (Fig. 3) The closing of the circuit willbe effected by means of the contact-pieces7c whenever a molding touches a cam g- After beinggreli-eved through the camsm, the bottom flaps it will returnto their closed position.

The opening of the closing flaps maybe arranged in the same way, eitherc ltirely me,- chanically bymeans of lever-transmission and similar devices or by pneumatic or liy draulic designs. In any way must attention he paid, that the action of the key upon the cam will take place in a quick and sure manner.

. The arrangement according to the invenwhereby the clamping I one and drop out through the bottom-open- 7 ing of the hopper. It is possible in this way to deliver moldings without regard to their dimensions at a defined place.

It will be clear, thatthe assorting and de livering of moldings or similar material of any dimensions may be arranged accord ing to the invention in the most simple and cheapest manner.

lVhat I claim'is:

1. A molding assorting apparatus, comprising a travelling conveyor, a series of molding-receiving receptacles carried by and'movabl-e with said conveyor, said receptacles having discharge openings at their lower ends and adapted to support moldings with portions of the latter projecting beyond the receptacles, and a series of gage bars projecting into the path of the moldings and adapted to position the latter in the receptacles for discharge through the said discharge openings.

2. A molding assorting-apparatus, comprising a travelling conveyor, a series of .molding-receiving receptacles carried by the upper ends of the receptacles, and a series of gage bars graduated in size projectlng into the path of the moldings and adapted to position the latter in the recep-- tacles for discharge through the said discharge openings.

3. A molding asorting apparatus, comprising a travelling conveyor, a series of molding-receiving receptacles carried by and movable with said conveyor, each of said receptacles being substantially inthe shape of an inverted triangle With a molding discharge opening in one Wall near the apex of the triangle, and a series of gage bars projecting towards the receptacles and adapted to contact With moldings in said re- I 30 cepta-cles. to cant the moldings and position them for discharge through the said discharge openings. v

4. A molding assorting apparatus comprising a travelling conveyor, a series of molding-recelving receptacles carried by series of fixed gage bars projecting into the v path of the extensions to engage the latter and position the moldings in the receptacles V for discharge through the said discharge openings.

In testimony whereof I hereunto afiix my signature.
