Ualih, executrhr of said Sterl F. Taylor, deceased, assignor, by mesue assignments, to Tamaker Corp, a corporation of Qalifornia Filed Mar. 1, 1%3, o'er. No. 262,4)S7 2 Claims. (Cl. 108-74) This invention relates. generally to the baling of trash and more particularly to an improved portable apparatus for facilitating baling of trash directly at trash sites.

Conventional trash equipment for forming bales of trash is usually located at a permanent site and the trash brought to the baling apparatus from various locations in trucks. in baling the trash, relatively complex equipment has been employed to compress the same into a given sized bale for easy storage or subsequent re-use by paper product mills and the like.

With the above in mind, it is a primary object of this invention to provide a novel portable apparatus for baling trash, in which the apparatus may be driven directly to a trash site and trash loaded therein and compressed into suitable bales of standard size.

More particularly, it is an object to provide an improved portable apparatus for baling trash particularly adaptable to waste paper, cardboard, and the like to form compressed bales at a trash site which may subsequently be loaded onto commercial vehicles for transportation to any desired location to the end that the immediate disposal of trash is greatly facilitated.

Still another important object is to provide a portable apparatus for baling trash meeting the foregoing objects which is rugged in construction, economical to operate,

and may easily be transported to any desired site by conventional commercial vehicles.

Briefly, these and further objects and advantages of this invention are attained by providing a basic frame structure having wheels to facilitate the portability of the structure. A trash receiving enclosure is mounted on the frame structure and includes compressing means within the enclosure so that trash received within the enclosure may be dispensed therefrom in compressed form and in a regulation sized bale.

The invention thus contemplates the steps of loading trash into an enclosure; moistening the trash; compressing the trash to a smaller volume in the enclosure; loading additional trash into the enclosure; moistening the additional trash; compressing the additional trash against the first mentioned trash; repeating the last mentioned three steps a plurality of times until a compressed bale of trash of given volume is formed; and then unloading the compressed bale of trash from the enclosure. The .roistening step serves to bind the material together and cause it to adhere in a given compressed shape cor responding to a commercial bale.

The preferred apparatus includes an enclosure and compressing means within the enclosure as described. Preferably, hydraulic means are employed for effecting the compressing operation. The enclosure itself includes a lower front gate and upper rear gate and incorporates a platform adapted to be raised between lower and upper positions to effect the compressing operation. By this arrangement, trash may readily be loaded into the lower front gate from a trash site without having to raise the trash beyond a minimum distance. On the other hand, when the same has been compressed by raising of the platform to squeeze the trash against the ceiling of the enclosure, the completed bale is disposed at a higher level and when removed through the rear gate is in a proper position for reception directly onto a commercial vehicle for subsequent transportation.

"ice

Various features of novelty in the portable apparatus include the arrangement of hydraulic units for actuating the system and the provision of unique means for enabling the trash to be compressed against the ceiling of the enclosure as well as unique means for facilitating the unloading of a completed bale.

The foregoing will be better understood by now referring to a preferred embodiment of the invention as disclosed in the accompanying drawings, in which:

FIGURE 1 is an overall perspective view of the portable apparatus for baling trash in accordance with the invention;

FIGURE 2 is a fragmentary cross sectional front view taken generally in the direction of the arrows 2-2 of FIGURE 1;

FlGURE 3 is a side view partly in cross section taken generally in the direction of the arrow 3 of FIGURE 1;

FIGURE 4 is an enlarged fragmentary cross section of a portion of the structure of FIGURE 3 enclosed within the circular arrow 1; and

FIGURE 5 is a schematic diagram illustrating the hydraulic circuits for operating the various components of the structure illustrated in FIGURES 13.

Referring first to the lower portion of FIGURE 1, there is illustrated a basic frame structure 1% having wheels 11 for rendering the structure portable. As shown, the frame structure supports a trash receiving enclosure 12 generally of box shape. This enclosure includes front and rear walls 13 and 14, sidewalls 15 and 16, a lower floor or bottom wall 17 and a top wall or ceiling 18.

A portion of the front wall 13 includes a front gate 1h mounted for swinging movement at 19' along the lower front longitudinal edge of the bottom wall 17. The rear wall 14 in turn includes a rear gate 20 which is mounted for swinging movement along the upper rear longitudinal edge of the top wall 18 as at 2%. Included within the enclosure is a platform 21.

With particular reference to FIGURE 2, there are provided platform raising and lowering means for the platform 21 in the form of a pair of hydraulic cylinders 22 and 23 secured to the frame structure on opposite sides of the enclosure 12. As shown, these cylinders include piston rods 24 and 25 coupled at their upper ends to pull rods 26 and 27. The lower ends of the pull rods in turn connect to opposite sides of the platform 21. The sidewalls 15 and is, as best shown in FIGURE 1, include elongated slotted open portions for accommodating the upper ends of the pull rods 26 and 27. Guiding means for the upper ends of the piston rods 24 and 25 in the form of angle irons such as indicated at 23 and 29 are provided and extend a considerable distance above the top wall 18 of the enclosure. The arrangement is such that actuation of the hydraulic cylinders 22 and 23 will serve to raise the platform 21 from a lower position juxtaposed the front gate 19 to an upper position juxtaposed the rear gate 29.

Referring to the side cross sectional view of FIGURE 3, the front gate 19 is arranged to be actuated by a hydraulic cylinder 30 disposed beneath the frame structure 16. This cylinder 30 is mounted for swinging movement and includes a front projecting piston rod 31 coupled to a suitable push bar 32 in turn rigidly secured to the front gate 19. Outward movement of the piston rod 31 will serve to close the front gate 18 whereas retracting movement thereof will serve to open this gate.

Similarly, the rear gate 29 is arranged to be actuated by a hydraulic cylinder 33 disposed along the top wall 18 of the enclosure. As shown in both FIGURES 1 and 3, this cylinder 33 actuates the rear gate 29 through the medium of a flexible cable 34 secured to a rigid bar 35 extending normally from the plane of the rear gate 29. The cable then passes about a pulley 36 and is secured to the front of a piston rod 37 projecting from the clylin der 33. Hydraulic actuation of the cylinder 33 will thus I 13-. This front wall 13-includesa key hole type slot 40 through which the piston'rod 39 for the cylinder 38 projects. Actuation of the hydrauliccylinder 38 will extend the piston rod 39 to push a bale 41 of trash from the up per portion of the enclosure through the rear gate 20. t

In accordance with one feature of this'invention, the

upper interior'corner portions ofthe rear gate 20 include rigid bars 42 extending normally from the plane of the line 2will be connected to the line 55 so that high pressure passes into the line 54 to the upper ends of the cylinders to lower the pistons, fluid from the lower ends of the cylinders passing-through line 52 to line 55.

As also, shown in FIGURE 5, the front gate cylinder 30 is'arranged to'be operated-by hydraulicfiuid pressure in the line 52 through a branch-line 56 passing through a hand valve '57. When the piston from the cylinder 30 is extended as "by high pressure passing through the valve, the front 7 gate will be closed. This action may-take place substantially simultaneously as the lift cylinders commence operation; that is, whenhigh pressure is on the 7 line 52 from the four-way valveSl. On the other hand,

gate so that when the gate is swung outwardly, the bars a 42 will swing downwardly to bear against the upper surface ofthe bal'e41 and tilt the same to facilitate its removal from the enclosure;

' As shown in FIGURE 3-, the frame It! also serves to support a'source of hydraulic fluid 43 cooperating with a hydraulic pump 43' for supplying hydraulic fluid under pressureto the various cylinders. By this arrangement,

the unit is entirely self-contained.

In accordance with a furtherfeature of the apparatus, there is provided means for moistening trash received through the front gate 19. This means takes the form of a header pipe 44 also shown in FIGURE 1 arranged to receive water under pressure from a suitable pump (not shown) connected to a water tank 45 disposed beneath the front gate structure 19 as shown in FIGURE 3. The same drive for the hydraulic pump 43' may be used'to drive the water pump for pumping spray water from tank when it is desired to retract the cylinders and open the front gate preparatory to receiving further trash, high pressure on the line 53 wil l:be passed through a branch line 57 to the otherend of the cylinder 30 to retract the piston rod therein; Return fiuid from the right hand end of the cylinder will then pass thrdugh thevalve 57, and line 52, to the return line 55. c v t The rear gate cylinder 33 shown in the lower left-jhand earner of FIGURES in turn is arranged to be actuated 45. By moistening trash received through the front gate,

preparatory to its being raisedby the platform 21 to form a bale, the trash will tend to. adhere together and bind more easily. J

As will be evident from the front view of FIGURE 2 by high pressure fluid'from thepump 43' passing through a branch line 59 and a'hand valve 60. This fluid enters a four-way valve 61 similar to the valve 51 which is capable of providing high pressure on either one of two output lines 62 or 63. When pressure is applied to output line 62, the piston for the cylinder 33 is extended to open the rear'gate. When high pressure is provided on the line 63, the piston inthe cylinder 33 will retract permitting therear gate to close. t r

Cooperating with this same four-way valve 61 is the cylinder 38 for ejecting the bale as described in conjunction withFIGURE 3. This cylinder may be operated to push the bale from the upper portion of the enclosure at the same time that thejreargate cylinder 33 is operated, and towards this end, there is provided a branch line 64 passing through a hand valve 65 to the righthand end of the cylinder 38 V v a V when the reartgate is retracted or. closed, the fluid passing through the line 63 also passes to the left end The wall is shaped such that the element '46 may swing from a horizontal position generally upwardly towards a vertical position to lie substantially co-planar with the wall.

by a stop structure 48 abutting the rear end of the element 21, it willpush past the elements 46 swinging them upwardly as indicated in dotted lines in FIGURE '4; 'When the trash has passed the elements, they will falltto their horizontal positions by gravity and thus engageunder the However, the element 46 is locked against down-' ward swinging movement beyond a horizontal position J of the cylinder 38 to retract the to the formation of another bale.

piston rod 39 preparatory From the foregoing description, the operation of the overall system willbe evident. Initially, and with referenoe to FIGURE 3, the rear gate 20 is closed and the front gate 16 swung open by operation of the hydraulic cylinder 30. Further, thetplatform 21 is in its lowermost trash that has been raised so that theplatform 21 may be lowered preparatory to receiving additional trash.

Referring now to FIGURE 5,rthere is illustrated a 7 simple schematic diagram of the interconnections between 1 I 60 the various cylinders described in conjunction with FIG? URES 1 -3. As shown, the source 43 and pump 43' pro vide hydraulic fluid under pressure along a first line 49 to a hand operated valve 50. From the valve 50, the fluid under pressure passes to a four-way valve 51. Depending upon the position of this four-way valve'51, hydraulic fluid under pressure can be'provided, on output. line"52 or 53. When provided on o'utputli'ne 52, the fluidwill pass to the lower ends of the cylinders 22 and 23 to raise the pistons. therein, fluid above these; pistons then passing 'out the line 54. The fluid in the line 54 then passes down line 53 which functions as areturn line when the. fourposition as shown in. dotted lines in FIGURE 3. Under 7 such conditions, trash directly from a trash site readily may be loaded onto the platform 21 and this job may be carried out very easily since the platform level is relatively low as compared with the rest of the structure. When a certain'amount of trash has been inserted through the front gate, thefront gate 19 is swung closed by actuation of the hydraulic cylinder 30." Simultaneously, water from the spray headerpipe 44 may be ejected to moisten the trash. i

Y Asrthe gate 19 is being closed, the lift cylindersZZ and 23 may be actuated through the high pressure line 52 from the four-way valve 51 described in FIGURE 5 to raise'the platformZL 'Ihe trash will thus be compressed againstthe top wall 18 of the enclosure, and as the trash passes the various elements 46 pivoted to thefront and ,rear walls,these elements will be retracted and then by gravityffall to horizontal positions 'to engage under the way valve is in the position described, the returnfluid passing through a line to the reservoir 43.

If the four-way'valve is moved in the opposite-direction, high pressure will be provided on the line 53, and the edges of thefcompres'sed trash. 7

'After the trash has beeninitially compressed-,the platform is lowered withtherear: gate 20 held closed and the front gate19 again' opened to receive furthertrash. This further trash is then raised and'compressediagainst the trashalready being held in the, upper portion of; the en-' closure by the elements 46. The additional trash-supplied to the -platform-isrmoistened-by water from the header pipe 44 so that it will adheretogether and be compressed into a solid mass with the first trash already disposed in the upper portion of the enclosure.

The foregoing process may be repeated a plurality of times until a relatively large bale is formed in the upper portion of the enclosure. When it appears that further compression is not feasible because of the mass of trash present in the upper end of the enclosure, the rear gate may be actuated and at the same time the cylinder 38 operated to extend the piston 39 and urge the bale 41 shown in FIGURE 3 from the upper portion of the enclosure. In this connection, opening of the rear gate 20 will cause the bars 42 to engage the upper top portions of the bale 41 to tilt the same as illustrated and thus facilitate its removal from the enclosure.

Since the rear gate portion of the enclosure is at a higher level than the front gate portion, commercial type trucks having rear platforms may be positioned substantially level with the rear of the machine of FIGURE 3 so that the bale may be received directly thereon. Thus, an important feature of this invention resides in the fact that during the compression operation, the mass of trash is actually raised to a higher level to facilitate loading onto commercial type trucks.

After the bale 41 has been removed from the upper end of the enclosure as illustrated in FIGURE 3, the rear gate is closed and the platform 21 lowered and the front gate 19 opened preparatory to receiving further trash. The various plurality of compression and moistening steps are repeated until another bale is formed and this latter bale is then ejected in the manner described for the bale 41.

From the foregoing description, it will thus be evident that the present invention has provided a greatly improved portable type apparatus for baling trash. While only certain components in the apparatus have been shown and described in accordance with one embodiment of applicants invention, it will be evident that equivalent steps and components could be substituted without departing from the scope and spirit of this invention. The improved portable apparatus for baling trash is therefore not to be thought of as limited to the exact embodiment set forth merely for illustrative purposes.
