The present invention relates to a multi-purpose vehicle designed for military use in the form of a tractor having a combination bulldozer blade and loader bucket and having a bowl capable of receiving earth from the bucket.
in military use, it is desirable to have a relatively light machine capable of high speeds and designed for various uses. Bulldozing of earth requires machine weight so that the heavy loads encountered in bulldozing will not cause slipping or breaking away of the tractor tracks from the ground.
One object of the present invention is to provide a vehicle having a loader bucket in which the bucket is capable of use in the ordinary manner for moving material or loading it into a truck and also capable of loading material into a bowl of the tractor provided for that purpose for transport of the material or for the purpose of increasing the overall weight of the tractor making it more eficient in bulldozin g operations.
Another object of the invention is to provide a vehicle capable of carrying troops and capable of amphibious operation.
Further and more specific objects and advantages of the invention are made apparent in the following specification wherein the invention is described in detail by reference to the accompanying drawings.
in the drawings:
FIG. 1 is a schematic view in side elevation of a machine embodying th present invention;
FIG. 2 is a plan view of the same machine;
FIG. 3 is a fragmentary view in side elevation of the forward portion of the machine only with portions broken away to disclose the door opening mechanism of the ballast compartment or bowl of the machine;
FIG. 4 is a fragmentary plan view taken on the line IV-IV of FIG. 3 with the doors shown in closed position; and
FIG. 5 is a similar view with the doors shown in open position.
Referring first to FIGS. 1 and 2, the machine of the present invention is shown as a track-type vehicle having the usual track mechanism generally indicated at and having a rear housing 11 for containing power means (not shown) and an operators station. The forward portion of the vehicle consists principally of a ballast compartment or bowl generally indicated at 12 which may be closed at its forward end as by a pair of swinging doors 13 and the rear end by an ejector 14 adapted to be moved forwardly for ejecting the contents of the bowl by means of hydraulic jacks 15 which function in a well known manner.
The machine carries a combination bulldozer blade and loading bucket comprising a blade portion 17 with a bucket portion comprising side walls 13 and a bottom 19 pivotally connected with respect to the blade as at 2%} so that the blade serves as a back for the bucket. The blade is at least the full Width of the tracks of the machine as is desirable for bulldozing operations but the bucket is no wider than the ballast compartment or bowl so that it can load material thereinto in a manner presently to be described. The combination blade and bucket is carried at the forward end of a pair of lift arms, one of which is shown at 22 in FIG. 1, which are pivotally connected to the sides of the machine as at 23 and adapted to be raised and lowered as by a pair of double acting jacks 24 also pivoted to the sides of the machine. The combination blade and bucket is also pivoted to the ends of the lift arms as at 25 and a pair of hydraulic jacks 26 interconnect the lift arms and the blade for tilting the bucket with respect to the lift arms and about the pivots 25. Bucket actuating jacks shown at 28 in FIG. 1 are pivotally connected with the back of the blade and with the sides of the bucket as at 29 for swinging the bucket sides 18 and bottom 19 about the pivots 29.
Several typical positions of the blade and bucket are shown in FIG. 1 wherein the full line position is that used for loading the bucket or for bulldozing with the blade when the sides and bottom of the bucket are swung upwardly. When the bucket has been loaded, the entire assembly is swung back to the broken line position illustrated at A by retraction of the jacks 26. With the bucket in this position, the lift arms may be actuated to swing it upwardly to the extreme position shown at B wherein the contents of the bucket have been deposited in the ballast compartment or bowl 12. In this manner, the ballast compartment can be loaded to increase the weight of the tractor and thereby increase its efficiency as a bulldozing machine. Where the bucket is to be used only for moving earth from one position to another or for loading a truck or other transport vehicle, it is raised by the lift arms only to the position illustrated at C. The bucket jacks 28 are then retracted to swing the side walls and bottom of the bucket forwardly as shown in broken lines at position C permitting discharge of the bucket contents. Complete discharge may also be facilitated in this position by extension of the tilt jacks 26 to move the bulldozer or back portion of the bucket to the forward position shown. Thus the machine is capable of loading its own ballast and capable of use as an ordinary bucket loader as well as a bulldozer which may be used for heavy bulldozing operations as well as light grading and scraping operations.
The ballast compartment or bowl of the machine is also available for use in transporting material or troops and serves as a floatation compartment to enable amphibious use of the vehicle in such transporting service. To this end, the doors 13 are provided with suitable seals which do not form a part of the present invention but are partially illustrated in FIGS. 4 and 5 at 30. The doors 13 are, at best shown in FIGS. 3, 4 and 5, hinged as at 32 to opposite sides of the machine with inclined mating edges at their central dividing point which embraces the seal shown at 30. Suitable seals, not shown, are of course also arranged around the other edges of the doors. The doors are actuated by hydraulic jacks 33 pivotally connected with a crank 34 on the upper end of a crank pin 35 journaled in brackets 36. The same crank pin carries an arm 37 at its lower end pivotally connected with a link 38 also pivotally connected to a bracket 39 on the door. The closed position of the door and actuating mechanism is illustrated in FIG. 4 and the fully open position is illustrated in FIG. 5. In the closed position illustrated in FIG. 4, the centers of the pivot pins at the end of the links 38 are shown as disposed slightly inwardly of the center of the crank pin 35. Consequently with this over-center position, pressure on the insides of the doors does not tend to open them and hydraulic pressure in the jacks 33 is not relied upon to hold the doors firmly in their closed position. The doors are opened for loading cargo or troops and are also opened for ejecting ballast or other loads upon forward movement of the ejector 14. All of the door actuating mechanism is contained in separate sealed compartments disposed on opposite sides of the bowl 12.
We claim:
1. A multi-purpose vehicle comprising a combined cargo space and ballast compartment, a bulldozer blade disposed forwardly of the vehicle, side walls and a bottom plate pivoted to the bulldozer blade to form a loader bucket therewith, means to swing the blade and bucket elements upwardly and over the ballast compartment to deposit the bucket contents therein, means to swing the bucket elements forwardly to discharge the bucket contents forwardly of'the vehicle, doors for closing the end of the ballast compartment, power actuated opening and closing means for the doors and means sealing the doors against entrance of water into the ballast compartment.
2. A multi-purpose vehicle comprising a combined cargo space and ballast compartment, a bulldozer blade disposed forwardly of the vehicle, side walls and a bottom plate pivoted to the bulldozer blade to form a loader bucket therewith, means to swing the blade and bucket elements upwardly and completely over the ballast compartment to deposit the bucket contents into the compartment throughout its length, said means also being controllable to swing the blade and bucket elements upwardly and forwa'rdly of the vehicle, and means to swing the bucket ele- 4- ments upwardly and forwardly of the blade to allow a controlled discharge of material forwardly of the vehicle, said blade being substantially as wide as the vehicle, and said bucket elements being no wider than the ballast compartment.
