' zam EN-T OFFICE BALING PRESS Barry W. Jonesand Guilford Glaser, Knoxville, 'lenn., assignori to. Dempster Brothers, Incorporated Tennessee 011th Serial more particularly to means for compacting the charge in the charging box preliminarily to the baling operation. The invention possesses particular utility in conjunction with baling presses for baling scrap metal, and therefore it will be I illustrated and described in its application to baling presm of that character, but as will be apparent to those skilled in the art the invention in its broader aspects possesses utility for application to baling presses of other types.

Commonly used baling presses for baling scrap metal include a charging box into which the ma-' terial to be baled is dumped in any suitable way, afterwhich the top opening in the charging box is closed by a horizontally movable door which slides on the top of the box-into cooperating relationship with certain wedging mechanism at the forward end of the box. Thereafter suitable compression heads, operable by rams disposed at right angles to each'other, are operated in sequence to crush and compress the material into a bale. As is apparent, vmaterial charged into the box must not project above the edge of the box because any material projecting through the open top of the box will interfere with the closing of the door. Furthermore, it is desirable that the material in the box be disposed compactly so that the ultimate bale will contain as much material as permitted by the capacity oi the press to crush and compress the charge. To avoid upwardly projecting material and to secure compactness of the charge in the box preliminarily to the baling operations considerable manual labor has necessarily been entailed in arranging the material, in the box. It is also common practice for foot tamping to be applied to the charge in order to compact it in the box, but the effectiveness of this manner of compacting the charge is limited by the weight of the workman and manual rearrangement oi pieces within the box is frequently required even when foot tamping is used.

It is an object of this invention to provide a b'aling press of the character referred to with mechanical means for compacting the charge in the box and thereby avoiding the necessity for manual arrangement of the pieces or foot- Another object of this invention is to provide an improved device of the type characterized which is capable of producing such a compact charge in the box preliminarily to the baling operations as would otherwise be obtained only by the exercise of extreme care in arranging the charge in the box.

, Knoxville, Team, a corporation 'of No. 2,616,812, dated November 4, 1852, No. 89,438, April 25, 1949. for reissue February 8, Serial 11 Claims. (Ci. Is-0.5)

Application No. sages:

Another object of this invention is to provide an improved device of the type characterized which facilitates the use of mechanical means for dumping the charge into the charging box by avoiding the necessity for rearrangement of the charge after it has been dumped.

Another object of this invention is to provide an improved device of the type characterized which may be readily applied to existing presses as well as incorporated in new presses, and which is of such character that it may be readily operated by unskilled labor.

Another object of this invention is to provide an improved device of the type characterized which is strong and durable, composed of parts that are inexpensive to fabricate and assemble, and simple in operation.

Otherobjects will appear as the description of the invention proceeds.

By way of summary, the present invention includes a compacting device associated with the charging box and its door and compression heads and provided with mechanical operating means, preferably a -fluid operated device, for moving said compacting device bodily into and out of the open top of the charging box to compress the charge therein, so as not only to free the opening of the box from upwardly projecting pieces which would interfere with the closing of the door but also to eiiect a compacting of the charge in the box by mechanically applied pressure.

The invention is capable ofreceiving a variety of mechanical expressions, two of which have been illustrated on the accompanying drawings, but it is to be expressly understood that the drawings are for purposes of illustration only, and are not to be interpreted as a definition of the limits of the invention, reference being had to the appended claims for that purpose.

In the accompanying drawings wherein the component mechanism of the baling press, to the extent that it is already available on the market, has been shown diagrammatically to avoid complication as to details constituting no part of the present invention,

Fig. 1 is a side elevation of a baling press in-v corporating the present invention;

Figure 2 is an end view of the baling press of Fig.1;

Fig. 3 is a side .view, to an enlarged scale, of the compacting device and its operating mechanism;

Fig. 4 is a top view of the mechanism shown in Fig. 3; and

saver Fig. is a side view of an alternative embodiment of the compacting device and its operating mechanism.

Referring in detail to the accompanying draw- Ings. wherein the same reference characters are employed in the several figures to designate corresponding parts; III is a base frame, of any suitable size and construction, with which is associated a rectangular charging box II. of any suitable size and construction, having an open to II.

lidably mounted on the base frame I0 is a door I3, shown in its open position in Fig. 1, the forward end of the door being designated It. Door I3 is mounted on suitable rollers II and It so that it may be slid to the right as viewed in Fig. 1 to close the open mouth I! in the box II, in which latter position the forward end I! of the door cooperates with suitable wedging mechanism carried by a. suitable bracket II to lock the door against upward movement. To slide the door into and out of its closed position said door is connected by any suitable connecting means I3 to the piston rod I3 of a hydraulic ram 20 supported in any suitable brackets 21 from the base frame III. The frame also carries an oil tank 22 onwhich is mounted a motor 13 for driving a suitable pump to develop hydrostatic pressure for use in the ram 20 and in the other hydraulic devices to be referred to. Suitable controls are indicated at 26.

Referring to Fig. 2, a hopper 23 is pivotally mounted in association with one side of the charging box II. and is actuated by a hydraulic device 21 so that when the material to be baled has been delivered to the hopper 23 in any suitable way the hopper may be swung from the position shown in Fig. 2 to an inverted position sufficient to dump its content into the open mouth I2 of the charging box,

The rear side of the charging box is constituted by a main compression head 23, shown in dotted lines in Fig. 1 and in full lines in Flg. 5, saidmain compression head being connected to the piston rod 29 of a hydraulic ram 30 carried by the base frame Ill. After the door I3 is closed and locked, the ram 30 is operated to move the main compression head, to the right as viewed in Fig. 1. to crush and compress the material into the righthand end of the box I I as viewed in Fig. 1. That portion of a side wall of the box which is at right angles to the main compression head 23 and which is located at the forward end of the box II as viewed in Fig. 1 is constituted by a second compression head 3I, as shown in Fig. 2, that is connected to the piston rod 32 of a hydraulic ram. 33 also carried by the base frame Ill. When themain compression head 28 has completed its forward stroke, ram 33 is actuated to move the compression head 3| at right angles to the main compression stroke to crush and compress the charge into that corner of the box which is at the forward end of the box and opposite th ram 33, completing the bale. That portion of the bottom wall of the box which underlies the completed bale is constituted by the head of a hydraulic device 34, carried by a suitable support 35 at the underside of the box II, so that upon actuation of the hydraulic device 34 the finished bale, after the compression heads 23 and II have been withdrawn and the door II has been opened, may be elevated to at least the level of the open top of the box II to facilitate removal of the bale.

A Suitable hydraulic system is connected to the several hydraulic devices and includes suitable valves for admitting hydrostatic pressure to the hydraulic devices in proper sequence to effect the closure of the door It, the successive movement of the compression heads 23 and 3| on their baling strokes, and the actuation of the ejecting mechanism 34, all as well understood in the art. As the mechanism so fardescribed is to be found in baling presses already on the market, further description of the details of construction, arrangement and operation thereof is deemed unnecessary.

In conformity with the present invention an auxiliary compacting device is pivotally mounted at the side of the charging box I I and mechanically operated, preferably by fluid pressure, to compact the charge dumped into the charging box II, as by the hopper 28, as well as to free the open top I2 of said box to permit closure'of tse door I3.

Referring now particularly to Figs. 3 and 4, a platform It is provided in any suitable way at the side of the box, being shown as attached to the side of the box and supported from the base frame In by one or more suitable braces ll to provide adequat strength and rigidity. Spaced bearing blocks}! are secured to said platform in any suitable way, as by bolts and nuts 43, and pivotally mounted in said bearing blocks 42 is a stub shaft 44. Secured to said stub shaft 44 ad- Jacent the bearing blocks 42 are a pair of arms 45, which may be of any suitable construction to afford adequate strength and rigidity, being shown as of generally triangular shape in side view and formed of plates and angle irons so as to have a generally box-like formation. Secured to said arms in any suitable way is a compacting device 48 which may also be of any suitable construction so as to afford adequate strength and rigidity, said device being commonly referred to as a "compression door" and being so termed hereinafter. As illustrated, said door has a' generally rectangular box-like body portion 41, which may be built up of I beam and plates, provided with suitable reinforcing members 43, which may be extensions of the arms 45 and be formed of plates and angle irons, and transverse reinforcing plates 49, one of which designated 50 is secured to a rigid transverse member 5| which is also rigidly secured to the reinforcing members 43, said plate 50 and transverse member 46 bein also rigidly secured to the arms 45 in any suitable way. The under face of the body, 41 of the compression door is also preferably provided with a plurality of transversely extending projecting members 52 to aid in the compacting action by applying localized pressures on the material in the box and to resist transverse movement of said material under the pressure of the door.

Platform III also carries rigid elongated members 53 of any suitable construction forming a channel therebetween and through which passes a the stub shaft 4:4. At the right-hand end of said channel as viewed in Fig. 4 is a rigid transverse member 54 having lugs 55 in which is mounted, by means of a pivot pin 58, the end of a hydraulic cylinder 51 whose piston rod as is pivotally connected to the aforesaid cross pieces 5| by means of a pivot pin 59 mounted in lugs provided in any suitable way on said cross piece II. Hydraulic cylinder 51 is provided with any suitable fluid connections, not shown (compare 10 inFig. 5), for admitting hydraulic fluid thereto to effect the operation next to be described. a

The normal position .of the compr ssion door ll is shown in Fig. 2, i. e.. with the compression door 48 in an upright position so as not to obstruct the open top of the charging box I I. When a charge has been delivered to said charging box II, as by the hopper I8, hydraulic fluid is admitted to that end of the-cylinder l'l'which is adjacent its pivotal mounting, whereupon through the actuation of the piston rod ll pivtherefore the movement of the compression door CI to or toward the position shown in Fig. 3 will force into the box any pieces projecting through the open top of the box and also compact the material in the box. The compression door may, if desired, be operated a plurality of times during the filling of the box ll so as to assure that the charge therein is tamped to maximum compactness. When through operation of the compression door the charge has been adequately compacted and the opening at the top thereoffreed of any projecting pieces, the compression door is returned to the position shown in Fig. 2 through admission of hydraulic fluid to the opposite end of the cylinder 51, and thereafter the door I! is closed as before explained, whereupon the baling operation proceeds to the completion of the bale and the ejection of the same.

Fig. 5 illustrates an alternative embodiment wherein the compression door 40 has a box-like body 8|, which may be of the same or similar construction to that above referred to with respect to the body 41, the under face of the compression door being shown as provided with projecting members 6! for the purpose above referred to. Secured to the upper portion of the compression door 46, and shown as constituting reinforcing members for the door, are a pair of arms is pivotally mounted at 64 on lugs I5 provided in any suitable way on a suitable support at the side of the box. Pivotally connected to the arms 63 at 66 is a link 61 which is'pivotally connected at 88 to a second link 88 that is pivotally mounted at 10 on lugs H provided in any suitable way on an upright 12 associated in any suitable way with the base frame It. Also pivotally mounted on said upright 12 as by lugs II and a pivot pin 14 is a hydraulic cylinder 15 having a piston rod 16 and fluid connections II,

said piston rod being pivotally connected to the links 61 and G9 at the pivotal connection 88.

While the charging box II is being filled the hydraulic mechanism II, II is contracted to swing the compression door I. to an upright position in which position it may be stopped by a suitable stop member 'l'l provided in any suitable way on the upright 11. When the charge in the box II is to be compacted, fluid pressure is admitted to the cylinder II to force the compression door I to or toward the position shown in Fig. 5 so-as to free the open top of the box from upwardly projecting pieces and compact the charge in the. box as before described when the compacting operation has been completed the compression door is returned to its upwardly extending position, whereupon the door llflmay be closed as before explained and the bailing operations proceeded with. i

It will therefore be perceived that by the present invention a bailing press has been provided with a compression door which maybe operated from the same hydraulic system that'is .provided for actuating the other hydraulic devices already provided on the bailing prus and which,

when operated, exerts a compacting pressure on the charge in the box which is far in' excess of what can be obtained by foot tamping and which assures the freeing of the open top of the box from upwardly projecting pieces as well as a compacting of the material in the box to an extent which could otherwise be obtained only by the exercise'of great care in manually arranging the material in the box.

The compression door and its operating mechanism can be readily added to existing baling presses as well as incorporated in new presses, and in view of the simplicity of the operation thereof no particular skill is required to operate the same. The compression door may be readily built up of angleirons and plates with suitable reinforcement members so as to give it adequate rigidity and strength without excessive weight, and the component parts of the door and its operating mechanismare all of simple construction so that the parts are inexpensive to fabricate and assemble. Thereby a strong, durable and highly eflicient compression door has been pro-' vided which assures compacting of the charge without involving the manual labor or foot tamping heretofore required to secure maximum compactness in the box as well as the freeing of the hopper referred to, because the charge may be properly compacted after it is dumped into the charging box notwithstanding the heterogenous condition of the charge resulting from the use l of a mechanical loader.

While the embodiments of the invention illustrated on the drawings have been described with considerable particularity, it is to be expressly understood that the invention is not limited thereto, as the same may receive a variety of expressions, which will now be apparent to those skilled in the art, while changes may be made in the details of construction, arrangement, pro-' portion, size, etc., and parts illustrated may be replaced by equivalent parts, without departing from the spirit of the present invention.
