16 Claims.

This invention relates to an improvement in dirt handling devices and more particularly to those of the type used for scraping, hauling, and leveling.

In its preferred form, the invention comprises a device that may form part of, or be attached to, a tractor or other heavy duty vehicle, and consists of an adjustable loading, carrying, and emptying member located forwardly of the vehicle to which it is attached, being equipped with front end wheel support. In operation, the member precedes the powered vehicle.

Prior to this invention, dirt handling devices of this nature have consisted of a wheeled vehicle having a one or more element dirt carrying scoop, and were adapted to be attached to and towed behind a powered vehicle; Devices of this nature are primarily utilized in scraping up and hauling quantities of loose dirt. They are not intended to, and are generally incapable of dumping at exact locations, such as special fills over banks, etc., and, furthermore, cannot level the dirt thus hauled and dumped. This is due generally to the necessity of the powered vehicle preceding the dirt handling device to a dumping location, or, if the dumping device is capable of being backed into position by the powered vehicle, being provided with means for dumping in a direction and manner opposite to that of loading. The dirt handling devices, applied to or located forwardly of a powered vehicle, are in the nature of road scrapers, ditch diggers or shovels, and are individually incapable of digging or scraping, carrying, and leveling large quantitles of dirt.

The present invention is intended to eliminate the heretofore necessary use of several types of dirt handling devices by combining certain features, hereinafter described, in one device. To accomplish this, the dirt handling device is located forwardly of the powered vehicle and inoperation always precedes the vehicle. Thus the operator may keep the'powered vehicle on firm ground, load the device, raise it, carry and empty the dirt at a given location, and, through use of the same device, level'or bank the dirt as may be required. The operator is not required to turn around and divert attention from the direction of travel of the powered vehicle in the operation of the device. Furthermore, it is possible, particularly in road filling and grading work, to dig, carry, dump, and level large quantities of dirt with greater rapidity through the use of a single device, whereas, in the past this work has a scraper, dirt loader and carrier, and bulldozer. One of the objects of the invention lies in the provision of a dirt handling device that may form part of or be applied to the front end of a powered vehicle.

Another object of the invention lies in the provision of a dirt handling device, the forward end of which is wheel supported and the rear end attached to and carried by a powered vehicle.

Another object of the invention lies in the provision of a dirt handling device at the front end of a powered vehicle that is capable of loading and carrying large quantities of dirt for considerable distances and at a speed limited only by that of the powered vehicle.

Another object of the invention lies in the provision of a dirt handling device located at the front end of a powered vehicle that is capable of carrying, emptying, and leveling large quantities of dirt.

Another object of the invention lies in the provision of a device located at the frontend of a powered vehicle that may be used for surfacing or leveling dirt, as may be required, in the building and grading of roads.

Other and further objects and advantages of the'invention will be more fully understood from a consideration of the following specification taken in conjunction with the accompanying drawings; and in which Figure l is a side elevation of a dirt handling device embodying one form of the invention applied to the front end of a tractor of the caterp ar tvpe;

The wall 49 is capable of being moved from the rear to the front end of the scoop in any suitable manner, as, for example, through the use of hydraulic rams 53. These rams are secured one to each of the members l2, and include shafts 54 that are securely fastened to the wall 49.

Reference is nowhad to the drawings,.and particularly to Figures 1 to 6, inclusive, wherein one modification of a dirt handling device, embodying-the invention, is shown, being generally indicated by the reference numeral 10., The device comprises a 'frame ll having duplicate side members 2. These members may consist of upper and lower rails I3 and I4, connected by middle and rear vertical rails 15 and It. At their forward ends the rails 13 and I 4 are connected by a member I], the lower portion l8 of which is rearwardly offset to accommodate a wheel sup-' port for the device. The members l2 are spacedly joined by several cross members, such as indicated at I9, 2|, and 22. At the forward end of the device, a top cross' member 23 is provided.

Y By means of a suitable shaft or pin 24, the member 231s pivotally joined to the member 22. The ends of the member 23 extend beyond the sides of the device and terminate in downwardly projecting portions 26. A vertical opening is. made through the portion 26, and the shaft 21 of a fork 28 projects upwardly therethrough, beingfitted above the member 23 with a lever arm 29.' The arms of the fork 28 mount an axle shaft which carriesa suitable wheel 3|. I The arms 29 are pivotally connected through rods 32 with an arm 33 that projects upwardly into a gear housing 34.

Extending rearwardly from the housing 34 is a steering'shaft 36. 'A worm and gear structuxein the Ehousing '34 serves to transform rotational movement of. shaft 36 into lateral movement of rods; 32 and arms '29 for the purpose of steering wheels 3|. As shown inthe drawings, one-or more universal joints31 may be'provided to ac-- f commodate the shaft'36 to any type of powered vehicle. The shaft is, of course, provided with a suitable steering wheel 38.

Connecting the lower rails l4, somewhat forwardly of the cross member I3, is a shaft 33."

p This shaft is carried by the rails l3 in bushings spect to the frame ll.

4| and fitted with nuts 42. Between the members I2 is a scoop, generally indicated by the numeral 43. This scoop includes side walls 44 and base wall 45. The shaft .39 projects through a suitably reinforced portion 46 of the side walls '44,

adjacent the rear end of the scoop, and serves to mount said scoop for pivotal movement with re- The forward end of the base wall 45 may be formed with a scraper edge,

laterally beyond the width of the scoop and is suitable pressure source common in tractors of the type to which the invention is applicable, the

shafts simultaneously move forward, causing the rear wall 49 to move forward, in the same posi-' tion shown in Figure 1 to a position such, for,

example, as indicated in, Figure 3, in any suitable'manner, as by means of a'pair of small hydraulic rams 56. The cylinder of each of these rams is pivotally mounted on the outer face of the,upper rails l3 of the device, and the shaft 51 thereof is joined to a lug 58, carried by the side walls 44 of the scoop. It will be understood that these rams have positive support in all positions and, consequently, the operator of the device may incline the scoop 43 about its pivot to any desired extent.

The modification of the invention of the device above described is applicable, with only slight variation, to the front end of any of several types of powered vehicles. vention under consideration, it is applied to the forward end of a tractor of endless tread type.

r to the tractor.

From the foregoing, it will be understood that the scoop 43 may be pivotally lowered, by means of rams 56, into dirt digging or scraping position,

such as is indicated in Figure 3 of the drawings,

, tion of the wheels 3! throughmember '23 andshaft as. In other words, the tractor may be onv level ground and the wheels 3 i .on uneven ground,

and the scoop and frame ll will not be laterally strained or twisted. When the scoop has been filled with-dirt, the rams56 are again operated to raise the forward edge 41 out of contact with the ground. The load may now be transported to any given point, such, for example, as the edge -of a bank, and the operator may then actuate rams 53 which will move the rear wall 49 of the scoop forwardly, forcing the load therefromfat the desired location. If the dirt thusdumped is not positioned as desired, the operator may back the vehicle, tilt the scoop, and, since the wall 43 is still positioned atthe forward end thereof, use the device as a bulldozer.

'Reference'is now had to Figures 7 toll, in-

' clusive, wherein a modification of the dirt hansubstantially as shown, that may be extended dling device, forming the subject of the invention, is shown, being generally indicated by the In the disclosure of the inof a cross member 14. The cross member 14 is located just forwardly of a cross support 16. Centrally of the support 16 is a guideway 11.

A block 18 is mounted in the guideway 11 and has pivotal connection through a shaft 18 with the cross member 14. The upper end of the block 18 is provided with a member 8i, the ends of which extend laterally beyond said block. To

these ends are secured the ends of shafts 82, which constitute the exposed portions of pistons for hydraulic rams 83. The rams 83 may be formed in the support 16 and serve as a. variable support between the wheel support and the frame of the device. Hydraulic rams 83 have been shownsincetractors of the type to which the invention is applicable are frequently equipped to operate such rams. It will be understood, however, that other adjustable means may be employed.

The frame 65 rigidly mounts a scoop 84 that includes bottom and

side walls

86 and 81. A rear wall 88 is provided for the scoop and is movable from the rear to the forward end thereof by means of suitable connection with hydraulic rams 88 that are secured, in any suitable manner, to the side members 66 of the frame 65. Wall 88 may be provided with suitable guide blocks 8| that ride in channels 82 secured to the side walls 81.

The wheels 1I may be provided with a steering mechanism generally indicated by the numeral 84, or may be of the caster type and adapted to freely follow the direction taken by the tractor. When it is desired to use the device, the operator of the tractor causes rams 83 to lower the frame 65 and scoop 86 from the full to the dotted line positionof Figure 7. This brings the front or scraper edge of the scoop into contact with the ground and forward movement of the tractor causes dirt to be collected by the scoop. When the scoop has been filled, the operator actuates rams 83 to raise the frame and scoop. The load may nowbe moved toa desired location and rams 88 actuated to move the rear wall 88 of the scoop forwardly to evacuate the dirt.

Reference is now had to a further modification of the invention shown in Figures 12 to 15, inclusive, of the drawings. In this instance, the dirt handling device, generally indicated by the numeral 83, is applicable to a dual wheel-drive, rear-motored vehicle 88. As is mommon practice in dual wheel-drive vehicles for use with dirt handling devices, a pair of front wheels are necessary to maintain proper balance, and since the dual wheels are not separately powered, as is the case with caterpillar tractors, the front wheels are utilized to steer the vehicle. Under these circumstances, the device 83 may be made an integral part of the vehicle 84. Upper and

lower side members

86 and 81 extend forwardly of the forward vehicle wheels 88 and are laterally outwardly curved, being joined to or made integral with the side members 88 of the device. The side members 88 include lower rails IN, to the rear ends of which a scoop I82 is pivotally secured. The scoop includes bottom rear position of the motor of the vehicle.

and side walls I83 and I84. An adjustable rear wall I86 is provided for the scoop, being capable of movement throughout the scoops length through connection with rods I81 of hydraulic rams I88. By means of brackets I88, rams I88 are pivotally joined at their forward ends to the rails 81 of the vehicle in order that rods I81 may, at all times, move in a direction parallel with the scoop I82, whether it be in the carrying or digging and scrapingposition. Suitable guideways III may be provided in the side walls of the scoop to receive blocks I I2 that are joined to the upper comers of the wall I86. The forward ends of the side members 88 are connected by a substantial cross member II3 that is pivotally connected, through a shaft H4, with a cross brace II6. In the present disclosure this connection may be had through an element; II1 that extends over the cross members II 3 and ter= minates in a downwardly extending portion II8. Thus, the shaft Ill projects through the portion I I8 and the brace I I6, and pivotally positions the cross member 3 therebetween. Any suitable steering mechanism, such as heretofore described in connection with the other modifications of the invention, may be provided by which to turn wheels II8. These wheels are mounted in forks I2I that depend from the ends of the cross member II3.

In this last described modification of the invention any heavy load carried by the scoop I82 is, to some extent, counter-balanced by the The type of vehicle to which this modification is applicable is more mobile than a vehicle of the caterpillar tractor type and, consequently, the device may not only load itself, but rapidlytransport a load over a considerable distance and empty and position the load thus deposited. The scoop I82 is moved from the position of Figure 12 to that of Figure 14, in any suitable manner, as by a pair of hydraulic rams I22. These rams may be positioned substantially as the rains 56 shown in the modification of Figure 1 of the drawings.

A still further modification of the invention, as applied to or forming the forward end of a powered vehicle, is shown in Figures 16 and 17,

to which attention is now directed. In this modification, the frame of a powered vehicle I23 extends forwardly of the driving wheels I24 and is attached to or made integral with a frame I25 that includes upper and lower side rails I26 and I21. Suitable vertical rails I28 and I28 connect the upper and lower rails. As shown in the drawings, the upper rail, rearwardly of the device, is integral with an upper rail of the vehicle frame I23. The rails I26 and I21, on each'side of the device, converge vertically to form a forward wheel-mount I38. These rails also converge inwardly from the sides, as may be clearly seen in .Figure 17. A suitable housing I3I is carried by, or may form part of the converging ends of the upper and lower rails I26 and I21. A member I32 abuts the lower end of the housing I3I and includes a shaft I 33 projecting upwardly through said housing. The support I 32 is connected through a pivot member I38 with an axle housing I35 through which a suitable shaft projects to mount wheels I36. The upper end of shaft I33 is fitted with an arm I31, to the free end of which suitable steering mechanism (not shown) may be attached. .Due to the pivotal connection of the support I32 with the axle housing I35, the wheels I36 are capabl of adjusting themselves, during use of the device, to uneven ground without canting or iniany way twisting the frame I25 'with respect to the vehicle of which it forms a part.

A rod I38 connects the rear ends of rails I2] claim as new andfor which I Letters Patent is:, v 1. A handling device for use with a powered vehicle comprising a frame rigid with the-frame of saidvehicle and projecting forwardly of and in-the line of travel of said vehicle,

' rams are operable, inanyconventional manner, by the operator of the vehicle to adjust the'scoopfrom one to the other of the positions indicated in Figure 16 of the drawings. The rear wall I45 of the scoop is movable forwardly to the front edge to evacuate a load of dirt, and, for this purpose, is connected with hydraulic rams I46. As in the modification shown in Figure 12, the rams are provided, at theirforward ends, with brackets lfl that. are joined through pivots I48 tothe frame I23 of the vehicle. The piston shaft I49 of each ram is rigidly connected, in any suit able manner, with the wall I45 and, when these rails I29 and, in the present instance carried by means. mounting a pair of wheels adjacent the forward end of said frame, said means being centrally pivotally joined to said frame to permit generally vertical movement of either of said wheels with respect tosaid frame, a scoop carried by said'frame, the forward end of said scoop being open and formed with a scraping edge of I a lengthat least equal to the width of said scoop, means. pivotally joining the rear end of said scoop to said frame and means for adjusting said scoop into and out of scraping and loading position.

Although not shown in this modification, suitable guides to prevent I jamming'or twisting of the wall I45 may be provided in the side walls of the scoop, substantially as has been heretofore shown and described in Figures 6 and 10 of the drawings.

The modification just described further increases the possible uses of the present invention in the handling of quantities of dirt, inasmuch as the scoop I39, with the wall I45 moved to the forward end thereof, may serve as a road surface scraper and. following suchwork, the wall I45 may be returned to the rear of the scoop and the surface material previously scraped gathered up in the scoop and conveyed to any desired location and evacuated. Following this, the device may be used as a bulldozer to position or level the dirt thus moved.

Applicant has shown and described several} modifications of the invention, but it will be apparent that in each modification the dirt handling device is located forwardly of the vehicle to which it is attached, or of which it forms an integral part, and by reason of this position, as well as the adjustability of the scoop and the rear wall thereof, the invention is capable of per-,

forming several types of work required in build- 1 ing and grading roads, as well as other work that was formerly accomplished through the use,

of two or more devices, either alternately attached to the same powered vehicle, or attached to separate powered vehicles. In other words, the

invention proposes to eliminate the present ne-I cessity of a powered vehicle for each piece of handling equipment by making possible the use quirements.

Although applicant has shown and described? vention in the form of a dirt handling device located forwardly of a-powered vehicle and adapted i to'excavate, scrape,- load, dump, and level, itwill i be understood that other modifications of the s only a few variations or modifications of his instructure described may be made and are con- 1 a templated insofar as these modifications are I I within the spirit and scope of the hereunto an- I nexed claims.
