Makay AttorneyDana E. Keech ABSTRACT: A sand bagger adapted for association with the rear end of the rearwardly tiltable body of a dump truck for receiving loose sand or soil from said body and including a power vibrated hopper equipped with an auger for uniformly distributing sand transversely in the hopper, the latter having multiple manually controlled gated bagging chutes for withdrawing sand from said hopper at a multiple of bagging stations.

SAND-BAGGING ATTACHMENT FOR DUMP TRUCKS .This. application is a continuation of application Ser. No. 826,754, filed Apr. 17, 1969, now abandoned, which in turn is a continuation of application Ser. No. 704,169 filed Feb. 8, I968, now abandoned.

SUMMARY OF THE INVENTION One of the objects of the invention is to provide a sandbagging unit which is quickly attachable to a dump truck for delivering loose sand or soil in a state of .vibration to an auger equipped hopper in which said sand is deflected equally to transversely spaced multiple sand-bagging chutes forrapid manual bagging.

Sand bagging is usually an emergency operation and speed is therefore essential. The standard procedures are well-.

known and slow.- Applicant desires to equip standardvehicles quickly with the emergency sand-bagging units that can be rushed to any location where operators can rapidly fill bags from multiple chutes and pass them on for placement at the point of need. There are many uses for rapid sand-bagging equipment such as the building of emergency levees to restrain flood waters, building barricades for riot control and erecting military field fortifications.

Applicant's theory of invention is to provide a separate and complete sand-bagging unit which can be used by itself or can be quickly attached for tailgate use on a conventional dump truck. The unit is entirely practical in that vibrated grated sand or soil is continuously deflected to multiple bagging chutes manually controlled for rapid bagging.

Another object of the invention lies in the special vibratory means and grating that insures unclogged delivery of loose' sand to the multiple bagging chutes.

Still another object of the invention is in the provision of a multiple auger sand-spreading mechanism delivering sand to special multiple transversely spaced chute areas.

These and other objects and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following description of a preferred embodiment thereof.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevational view of a preferred embodiment of the invention, partially broken away to show the bagging attachment in position of actual use; 7 FIG. 2'is a top plan view of the truck with the device installed thereon; v

FIG. 3 is an enlarged elevational view of the vibrating mechanism;

detached from the truck; and

FIG. 5 is an enlarged perspective view of one of the gated delivery chutes.

DESCRIPTION OF THE PREFERRED EMBODIMENT Before referring specifically to the drawings in which a preferred embodiment of the invention is disclosed,"it might be well to state that applicants device may be quickly attached to and detached from the standard dump truck. The tailgate of the truck is preferably removed and the multiplechuted sand bagger is connected to the standard fixtures with no difficulty whatsoever. The rapid sand-bagging I device becomes the tailgate and is in position for driving connection with the power-take-off, irrespective of its form. It is anticipated that in some instances, a separate power unit might be required. An air-cooled engine of known design can be easily attached to the separable unit and provide the necessary power. The dump truck is elevated in the usual manner by the hydraulic lift 12. The truck power-take-off 14 extends rearwardly as shown in FIGS. 1 and 2 and journals in a fixed bearing 16. The detachable bagging device has fittings such as 18 and 20. which secure the apparatus to the truck bed in an angular overhanging position as shown iii FIG. 1. The configuration of the bagger tightly secured the end of the truck during FIG. 4 is a perspective view of the sand-bagging apparatus travel and an apron 22 thereon presses against the truck bed and prevents exit of sand or soil.

The separately formed quickly attachable multiple sandbagging unit does not move with respect to the truck body but moves with it as clearly shown in FIG. 1. The bagging unit consists of a bottom or hopper 24 that assumes a horizontal position when in use. A solid end gate 26 rises from the hopper and has inwardly projecting side closure members 28 and 30. A top grating 32 projects forwardly from the end gate 26 and then passes diagonally backward at 34 to the end of the truck bed and adjacent the forward edge of the hopper 24. This prevents the entrance of any clogging sand or soil elements to the dispensing unit. An auger shaft 36 is rotatably supported in the sides 28 and 30 and has a driving end connection 38 with the truck power-take-off 14. The opposite end of the shaft 36 has a gear 42 mounted thereon for a purpose to be described later. The auger shaft 36 has six spaced auger blades 44 which are alternately oppositely pitched and which spread sand transversely and deliver the same substantially equally into hopper sections formed by half-pyramidal dividers 46. The grated sand or soil delivered by the device to the three hopper sections between said dividers then passes downwardly and outwardly through identical multiple bagging chutes 48 in a manner controlled by gates 50 which are manually controlled by levers 52.

A means for vibrating the sand bagger unit as well as the truck to which the unit is attached is provided in the following mechanism. A chain 54 connects the auger shaft gear 42 with a small gear 56 which is fixed on a vibrator shaft 58 which is rotatably supported in the sides 28 and 30 of the bagging unit. A vibrator 60 on the end of shaft 58 transmits a constant shaking effect to the sand bagger unit and the truck body so that the sand and soil in the truck body is fed evenly through the grating to the auger blades 44. It is to be understood that other modified types of vibrating mechanisms might well be used in the invention.

A grated platform 62 is suspended from the hopper 24 so as to underlie the bagging chutes 48 and provide a storage for bags and also a support for bags in the process of being filled with sand by the chutes 48. Dual hooks 64 on the sides of the chutes secure the sides of the bags to the chutes during the filling operation. It is apparent that operators quickly fill the sacks at the triple chutes and then shift the filled bags onto a conveyor 66 for supporting the bags while the open ends thereof are stapled closed and for transmitting the filled and closed bags to a position of use.

Iclaim: I

1. A sand or soil bagger comprising:

a hopper for receiving loose sand or soil and the like;

grate means for screening the sand or soil to promote a constant flow; a multiple of laterally spaced independent gate-controlled bagging chutes provided in the bottom of said hopper; and 1 power actuated means on said hopper for constantly vibrating said hopper and grate means thereby maintaining a steady flow of said sand or soil to and through said bagging chutes as the gates thereof are opened for filling bags with said or soil and a platform suspended on said hopper beneath said chutes for supporting bags being filled with sand or soil from said chutes.

2. A bagger as recited in claim 1 wherein power driven auger means is provided near the bottom of said hopper for distributing sand or soil received from said hopper transversely of the latter whereby said bagging chutes will all be uniformly supplied with sand or soil.

3. A bagger as recited in claim 1 wherein detachable attachment means are provided for mounting said hopper on the rear end of a tiltable body of a conventional dump truck whereby a rearward upward tilting of said body deliver or soil gravitationally from said body into said hopper and wherein the vibration of said hopper and grate means is transmitted to said truck body facilitating the smooth discharge of sand or soil from said body into said bagger.

4. A detachable sand-or soil-bagging unit adapted for replacing the tailgate of a conventional dump truck said unit comprising: a closed end portion forming at-its base a=sand or '.soil hopper when in position of useya sand or soil grating about the end portion for preventing clogging; multiple manually controlled gated chutes projecting from said hopper;
