5 Claims.

The present invention relates` to cooling and conveying means and is particularly useful in association with plastic forming machinery, e. g. briquette presses for continuously receiving and cooling While transferring the hot fuel briquettes as formed to a suitable discharge point.

Previous apparatus of this character has been open to the objection that the briquettes are sub- :lected to undue agitation, whence, because of their somewhat fragile initial condition, there results a rubbing of one against the other to the extent that in some cases the briquettes are disintegrated or their preformed surface contours are rendered so irregular as tointerfere with the salability of the product.

With these considerations in mind, I have de- `veloped a continuous type of conveyer for receiving the hot briquettes from the press and capable of conveying them with complete freedom `from pulsations. Furthermore, the conveyer is so constructed as to afford optimum cooling conditions for thebriquettes. In this manner, briquettes are continuously cooled while travelling under conditions which will prevent any substantial rubbing contact, with the result that the briquettes delivered to the discharge point are firm, have their desired preformed shape and are devoid of surface irregularities.

The construction is simple and easily adaptable with briquette presses now in use. Also, the conveyer being of the continuous type may be controlled as to speed and is so constructed that the cooling action is substantially uniform.

Various modifications in the construction may, of course, be resorted to and I have illustrated in the attacheddrawings and described in the folthe invention.

lowing specification one preferred embodiment of Referring to the drawings: Figure 1 is a side elevation of the cooling conveyer, but partly broken away and in section.

Figure 2 is a top elevation of the cooling conveyer.

Figure 3 is a section on the line 3 3 of Figure 1, and

Referring to Figure l, the continuous conveyer is mounted upon suitable supports IIJ, one at each end of the conveyer, and in which are carried sprockets II for causing the conveyer to be continuously moved. One ofthe sprockets is actuated by any suitable prime mover rotating its shaft Il'.

The conveyer includes a number of sections Ill., a

Which are united together in the manner now to be described. Referring to Figures 3 and 4, each section has two upstanding opposed plates l2 which are identical in construction, and the plates I2 on each side of the conveyer are disposed in longitudinal alignment. Each plate has a substantiallysrnooth inner side surface I3 and adjacent its base is thickened outwardly as shown at I4. At one end, the thickened portion is out away to provide a curved recess I5 comprehending the transverse area of the thickened portion and extending outwardly of the recess is the olfset integral boss I6 provided with an opening I'I. The opposite end of each plate at the thickened base portion thereof is provided with a longitudinal projecting boss I8 having a curved contour conforming to the contour of the recess I5 and provided with an opening I9 extending therethrough. The transverse area of the boss I8 is substantially equal to that of the recess l5 in which it is received so thatk when the ends or edges of succeeding plates are lined up to form the respective sides of the conveyer, the openings I'I and I9 will be in register, the plane end edges Z0 ofthe plates will be in substantially abutting relation as shown in Figure l and the faces I3 will form a continuous side Wall on each side of the conveyer.

The bottom of the conveyer includes a plurality of spaced grid rods 2| fitting in recesses or sockets 22 in the opposed plates I2 and spaced tie rods 23 whose reduced ends 24 extend through openings 25 in the plates. The rods 2l are of a length so that their ends abut the closed ends or bottoms of the recesses 22, and they are held in such positions by the tie rods 23, whereby a rigid structure is assured. The plates abut against the shoulders 26 on the tie rods 23 and l are maintained in position by means ofthe nuts 21 engaging the threaded portions 28 on the reduced ends 24 of the tie rods. It is to be noted that the rods 2i 23 are maintained spaced apart a distance sufcient to prevent briquettes, for example, from passing therethrough, andr such spacing also affords a maximum opportunity for the circulation of air to promote rapid and complete cooling of the briquettes.

The ends 'of the respective plates or sections are hingedly connected together by means of shafts 29 extending through the registering openings I'I, I9, which shafts at each end carry suitable rollers 30 held in position by Cotter pins or any other suitable means 3l. The rollers supporting the conveyer sections are moved by the prime mover actuated sprocket member over a III) suitable track 32 while the conveyer is moving in its upper horizontal position and are supported upon a track 33 when the conveyer is moving in its lower horizontal position. At the ends of the conveyer, of course, the sections are engaged by the sprocket members I I.

The conveyer construction just described is free of any pulsating motion such as would agitate or cause the briquettes fed thereto from a press to have a rubbing contact that might either disintegrate the briquettes or deform them. Moreover, the construction is such as to afford an optimum cooling of the briquettes so that their resistance to deformation progresses as they move from the press to the discharge point. This is important in that by controlling the speed of the rotation of the sprockets and hence the travel of the conveyer, Various briquette compositions can be cooled and conveyed and presented at the discharge end in such condition that subsequent handling will not injure the product.

It is to be understood that the conveyer may be of any desired length and width. In some cases, in order to strengthen and rigidify the slatted bottom dened by the spaced shafts 29, tie rods 23 and rods EI, I provide straps 34. As

shown in Figures l and 2 these straps consist ofk upper and lower members 35, 36 having complementary semi-circular recesses 31 therein to grip the respective spaced members forming the bottom, and the two sections 35-36 are bolted together as shown at 38. In the case of a narrow conveyer, one set of straps will be employed disposed substantially in central alignment, Whereas when the conveyer is relatively wide, the straps will be disposed in staggered relation as shown in Figure 2.

It will be noted, and as heretofore explained, that the conveyer has the adjacent end edges 20 of aligned plates I2 on each side of the conveyer in abutting relation as shown in Figures 1, 2 and 3, and that in the horizontal movement of the conveyer, the rollers being supported upon a continuous track 32, the conveyer sections are devoid of any irregular motion such as would shuffle the briquettes about and cause them to have a rubbing contact. In this connection, the straps 34 serve to rigidify and stiffen the bottom, as Well as the side walls in their abutting relation, so that the conveyer is further prevented from any irregular motion..
