3 Claims. (Cl. 214-82) This invention relates to improvements in compaction bodies of the type used for the collection of refuse, gar- .bage and the like, and having means therein for compacting such refuse during collection and for discharge therefrom.

Compaction-type bodies are usually provided with a compaction head mounted in the body, which is moved lengthwise thereof for compressing the material into the rear portion of the body as it is collected, until the body reaches the point of discharge, when the material may be removed therefrom. The compaction head must be moved throughout the major portion of the length of the body and to varying degrees therein during this compacting action, which involves a comparatively long stroke. It is impractical to use a hydraulic cylinder for movement of the compaction head lengthwise of the body, because of the extreme length of travel involved, whereby a long telescopic cylinder would give trouble in service and would not be practical.

One object of this invention is to overcome the objections noted as to the use of a hydraulic cylinder for moving the compaction head in a compaction-type body, and to provide for practical and trouble-free operation of the head therein.

Another object of the invention is to provide compound action mechanism for moving the compaction head in the body, whereby one type of action is provided for movement of the head throughout a portion of its stroke, and secondary operating means is provided for extending the movement of the head, either for compaction or discharge of the refuse.

Still another object of the invention is to provide separate hydraulic cylinders, acting in sequence in accomplishing movement of the compaction head throughout substantially the entire length of a compaction-type body to obtain the maximum stroke of the head in the body, with a minimum of trouble and difficulties in control and operation thereof by hydraulic pressure.

These objects are accomplished, according to certain embodiments of the invention, by mounting a compaction head in a body for movement lengthwise thereof. A hydraulic cylinder is connected with the head for causing movement of the latter. This horizontal cylinder is mounted on a platform, movable bodily relative to the body and connected with primary operating means, such as a second hydraulic cylinder, linkage or other operating mechanism, and which will act to move the plat form and thereby, through the horizontal cylinder, the compaction head. This primary operating means may function to provide an initial stroke sufficient for the normal compacting operation, or the horizontal cylinder may be acted in sequence, either to complete the compacting action or for discharge of the material from the body. This does not require an extremely long stroke of either hydraulic cylinder, and adequate control of the operation thereof may be provided without difficulty or trouble.

These embodiments of the invention are illustrated in the accompanying drawings, in which:

atent O Fig. 1 is a side elevation of a motor vehicle, showing a compaction body applied thereto, in which this invention may be used; I

Fig. 2 is a diagrammatic view of a portion of the hydraulic system;

Fig. 3 is a vertical section through the compaction body, showing the head in its forward position;

Fig. 4 is a horizontal section therethrough on the line 4-4 in Fig. 3;

Fig. 5 is a longitudinal section through the body, showing both cylinders extended, with the head in its discharge position;

Fig. 6 is a longitudinal sectionthrough the body, showing the head in an intermediate position, the primary cylinder being extended; 1

Fig. 7 is a longitudinal section through the compaction body, showing a modified form of head operating means and with the head in its rear discharge position;

Fig. 8 is a similar view, with the head in intermediate position;

Fig. 9 is a similar view with the head in its forward position; and

Fig. 10 is a longitudinal section through a compaction body constructed according to this invention and applied to a trailer vehicle. g

The invention is shown in Fig. 1 in connection with a motor vehicle chassis, generally indicated by the numeral 1, and including a self-propelled controllable vehicle usually having an operators cab, generally indicated at 2. Mounted on the chassis 1 is a compaction body 3 which may be of any desired or suitabe shape. The body 3 is provided with a hopper or other filling opening, generally indicated at 4, in the forward end thereof, and with a discharge opening 5 at the rear end thereof, usually closed by doors or other means for effecting discharge of the contents from the body. The details of the body are not shown in the drawings because the invention may be applied to many different types of compaction bodies and because the construction of such bodies is well known in the art and is not necessary to a clear understanding of this invention.

Operatively mounted in the compaction body 3, and movable lengthwise therein, is a compaction head 6 which extends substantially throughout the area of the body in the normal construction and having suitable guide means therefor within the body. The compaction head 6 is adapted for movement from the front end of the body at a point forwardly of the filling hopper 4, as shown in Fig. 3 to a point adjacent the rear end of the body at the opening 5 shown in Fig. 5. Means is pro-. vided, according to this invention, for effecting such extended movement of the compaction head substantially throughout the length of the body.

- In the form of the invention shown in Figs.. 2 to 6, we have provided a pair of hydraulic cylinders functioning as primary and secondary operating means for the head and acting in sequence thereon. The primary cylinder is indicated at 7 and may be of the telescopic type as shown. One end of the cylinder 7 is pivotally connected at 8 to the body 3 adjacent the front end of the latter and extends downward in somewhat diagonal relation therefrom to a pivot mounting 9 on a movable platform 10. The platform 10 is mounted for bodily move ment in the body 3 and .should be suitably guided therein, as, for example, on the same guide means as customarily provided for the head 6 or other suitable means provided therefor, so as to permit lengthwise movement of the platform throughout a substantial portion of the length of the body, as will be apparent from Figs. 3 to 6.

Mounted on the platform 10, or connected therewith for movement upon operation of the cylinder 7, is a secondary head moving means, illustrated in the drawings as e adjacent side of the compaction hea e cylinder 11 from the refuse in the body, but italso iii ill hlhtehtehthehh the. eyhhher t9 heh noted from ed t exlihde 1.1 e eh h the al h head. h t ee. e i slenehs eht there and i cas ble of movement relative thereto tothe several posiime l us ra ed h Fi s. 3 2 .121

As soon as the body is filled and the truck moved to the point of discharge, the cylinder 11 can be utilized to extend the stroke of the head 6 for. discharging the refuse hreh h th eveh h 5 a the a ehs e he he lrdesired, however. th cyl nd l 'may'h f z sl il mpa n e ti n to bhta n ehi h le hlsllfeh eht the head 6 and its use is not limited solely to the discharge of the material.

The compound action of the two cylinders 7 and 11 may be accomplished by first moving the manual control lever 18 (Fig. 4), as described above. This will result in hlh ehl h e e he 6 a a from, nd r let e t9. t Pla f m .0 t ieh. the hh et 7 h e h el e and hereby p e d s e m h e end n m h th lleh the action of the separate and respective cylindersfeitl 'er for compaction of the refuse or' for ejecting the latter from the body. v

The parts may be restored to their initial positions in a manner which will readily be apparent to those skilled in the art. While the valve 17 is held open by the operator, the hydraulic system is controlled so as m; withdraw the fluid from the .cylindenl l, to move the latter to its closed po s on, a shown ili Eig. "6, and'the'n to close the cylinder-7, shown in 3 During'thesc movements, the head 6 will be withdrawn inth ebody' 3 forwardly of the filling opening 4, ready for a new charge of material.

A modified form of the primary operating means is illustrated in Figs. 7 to, 9., wherein, in place of a telescoped primary cylinder, a simple cylinder, with power multiplying linkage, is used for accomplishing the compaction action of the head 6. In this form, the cylinder is shown at 27 pivotally connected at 28 and 29 between a pair of links 30 and 3 1. The link 31 is pivotally con nected at 32 to the platform 10 and the links are pivotally connected together at their adjacent ends at 3 3.. The link 30 is pivotally connected at 34 to the body 3 at the forward end of the latter.

Upon admission of hydraulic fluid to the cylinder 27, the latter is extended from the position shownin Fig. 9 to the position shown in Fig. 8 which has the effect of swinging the links 30 and 31 relative'to each other and thereby accomplishing a forward movement of'the platform 10 and of the head 6 in the body 3. i A much shorter strokeof the cylinder 27 may be utilized in cooperation with the links, to provide a substantial mQYi ment of the head, without requiring a telcscoped cylinder, as in the form described above, and yet suificient strioke can be obtained thereby. Then, upon operation of thesecondary cylinder 11, the head (can be moved rearwardly in the body 3, either for compaction of the material or for discharge of the material frorn the body. The hydraulic cylinders 27 and 11 may be connected together and operated in the same manner as described above'in connection with the cylinders 7 and 11.

A further modification is illustratedin Fig. 10, wherein the invention is applied to a compaction body 3 mounted on a trailer vehicle, the frame of which is generally indicated at ell'adapted to besupported'at its rear end on wheels, as usual. The frame 41 has a kingpin 52 on the front end thereof, which may engage and be carried by the fifth wheel of the tractor vehicle. This front end portion is indicated at 43 and is offset in a'verti'c'al' direction from the major portion of the length of the frame portion ,41, substantially in gooseneck shape. .The body 31 conforms to this offset relation, and the shield 12* extends downward, so as to conform to the lower portion of the body 3' over the frame 41.

Normally, a compaction body mounted on a trailer vehicle would extend only from the goosieneck or offse portion of that trailer vehicle, rearwardly. However, by mounting the operating cylinders 7 and 11 in the body, as described, and connecting them through the shield 12' with the head 6, and using this arrangement in a trailer, it is possible to locate these operating parts in the relatively lower height of the front end portion of the body, forwardly of the compaction head. Thus, the operating parts do not take up body capacity and it is possible therefore, to have a larger capacity body on the same length trailer. The operation thereof would be substantially the same as described above.

While the invention has been illustrated and described in certain embodiments, it is recognized that other variations and changes may be made therein, Without departing from the invention as set forth in the claims.

We claim:

1. In a compaction body for a motor vehicle comprising an elongated body portion adapted to receive refuse therein, the combination with a compaction head mounted in the body for movement lengthwise thereof, of a hydraulic cylinder mounted in the body and extending lengthwise thereof, a shield structure connecting the cylinder at one end with the head, a platform having the opposite end of the cylinder mounted thereon, said platform being bodily movable lengthwise of the body, a hydraulic cylinder connected at one end with the platform and at the opposite end with the body and operable for moving the platform and the first-mentioned cylinder to impart movement to the compaction head.

2. In a compaction body for a motor vehicle comprising an elongated body portion adapted to receive refuse therein, the combination with a compaction head mounted in the body for movement lengthwise thereof, of a hydraulic cylinder mounted in the body and extending lengthwise thereof, a shield structure connecting the cylinder at one end with the head, a platform having the opposite end of the cylinder mounted thereon, said platform being bodily movable lengthwise of the body, linkage connected with the platform and with the body, and a hydraulic cylinder operatively connected with the linkage for moving the latter to impart movement to the first-mentioned cylinder and to the head.
