ELEVATING MECHANISIE FOR DUIJIPING TRUCKS.
Application filed December 5, 1919. Serial No. 34:2,582.
Z '0 aZZ whom it may concern.
Be it known that 1,; Tnonnxs EUGENE 'VRIGHT, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Elevating Mechanism for Dumping Trucks, of which the following is a specification.
This invention relates to mechanism for elevating the bodies of trucks and is designed more particularly as an improvement upon the structure disclosed in Patent No. 939,782 issued to T. Wright on November 9, 1909.
One of the objects of the invention is to provide means whereby the amount of elevation of the body is materially increased without adding materially to the mechanism, so that the efficiency of the dumping truck is increased.
A further object is to provide lifting mechanism of thischaracter which is compact and durable and will operate smoothly and easily.
With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the preciseembodiment of the invention shown can be made without departing from the spirit of the invention.
In the accompanying drawings the pre-' ferred form of the'invention has been shown.
In said drawings Figure l is a side elevation of a portion of a truck showing the body elevated the maximum distance to position for delivering anthracite or like material therefrom.
Figure 2 is a similar view showing the body tilted for the purpose of dumping material onto the ground close to the truck.
Figure 3 is an enlarged section on line 3-3, Figure l.
Figure 4 is a section on line iet, Figure 1.
Referring to the figures by characters of reference 1 designates a motor driven truck of any preferred type and pivotally connect-' ed to the rear portion of this truck are rear supporting members 2 the upper ends of which are pivotally connected. as at 3, to the bottom portion of a body at at points back of the center of said body. Levers 5 are pivotally connected'to the front portion of the body at the sides of the bottom thereof and pivotally connected to intermediate portions of the levers 5 are front supporting members 6 pivotally connected, as at*7, to the truck. These members 6 are preferably formed of telescopically connected bars such as shown for example in my patent hereinbefore referred to. g
A thrust member 8-is mounted to travel along inclined guide rails 9 carried by the truck and the rear ends ofthese members 8 are pivotally connected by studs 10-to links 11 which, in turn, are pivotally, connected as at 12:to the lower ends of the levers 5.
Supplemental hoisting members 13 are pivotally connected to the body 1 at points between the members 2 and '6, as'shown at 14, and each of these members has a longitudinal slot 15' in which a stud 10 is adapted to ride, the lower end of each slot being offset as at 16 to form aseat for the stud 10 when the parts are positioned as shown'in Figures 1 and 2.
Chains or other suitable flexible means indicated at 17 are connected to the'body 4: and to the truck for the purpose of limiting the upward nmvement of the body, this chain or chains being attached to the body 4' in line with the pivot 8. Additional chains 18 orother flexible devices connect the lower ends of the supplemental members 13 to" the onto the ground close to the truck, the rear end of the body 4 is shackled to the truck by means of links 19 'or the like as shown particularly in Figure 2. 'By means of suitable mechanism shown generally at 20 in Figures 1 and '2 the thrust members 8 are drawn rearwardly along the inclined guide rails 9 so as to thrustthe links 11 rearwardly and cause the levers 5 to swing relative to the members 6. 2 will swing upwardly. carrying with them the supplemental members 13 which will be At the same time the members limited in their movement by the chains 18. The studs 10 gradually work downwardly in the slots 15 until they come into the seats 16 as shown in Figure 2, the thrust being transferred gradually from the levers 5 to the members 6 and then from said members 6 to the supplemental members 13 which being anchored by the chains 18, will swing upwardly and impart an additional elevation to the body 4, the members 6 being elongated during this final movement. Obviously this results in a very quick and abrupt dump of the body, as shown in Figure 2.
Should it be desired to raise the body 4 bodily, the links 19 are not fastened to the truck but are left free. Thus when the parts operate in the manner described, the body will not be restrained but will move upwardly with the members 2 to the elevated position shown in Figure 1.
It has been found in practice that by providing the supplemental elevating members 13 the elevation of the front end of the body a can be increased from 18 to 24 inches over what is possible with the structure disclosed in the patent hereinbefore mentioned.
While the present improvements have been shown and described applied to motor trucks it is to be understood that said im pliovements can also be used in connection with horse drawn trucks, trailers, tractors, or in fact any type of vehicle.
What is claimed is 1. The combination with a truck, a truck body, a rear elevating member pivotally co nnected to the truck and truck body, an extensible front elevating member pivotally connected to the truck, and a lever constituting a connection between the front ele-- vating member and the truck body, of a thrust member, means for actuating the thrust member, a link connection between the thrust member and the lever, a supple mental elevating member pivotally connected to the truck body and slidably and pivotally engaged by the thrust member, and flexible means for anchoring said supplemental elevating member to thetruck.
2. The combination with a truck, an extensible front elevating member, a rear elevating member, said members being pivotally connected to the truck, an intermediate. elevating member and flexible means for anchoring said intermediate elevating member to the truck, of a truck body pivotally mounted on the intermediate and rear elevating members, a lever connecting said truck body to the front elevating member, a thrust member, means for actuating the same, means operated by said thrust member for elevating the body successively through the lever, front elevating member and intermediate elevating member respectively.
3. The combination with a-truck, an extensible front elevating member pivotally connected thereto, a rear elevating member pivotally connected thereto, and a lever piv otally mounted on the front elevating member, of a truck body pivotally connected to the lever and to the rear elevating member, an intermediate elevating member piv otally connected to the truck body, and means for successively thrusting against the body through the lever, front elevating member and intermediate elevating member to hoist the truck body to higher elevation respectively. 7
l. The combination with a truck and a dump body movable relative thereto, of rear elevating member pivotally connected to the truck and body, a front elevating member pivotally connected to the truck, a lever connecting the body to the front elevating member, an intermediate elevating member pivotally connected to the :body, means for anchoring said intermediate elevating member to the truck, means for limiting the upward movement of the body, and means for thrusting against the body through the lever, front velevating member and intermediate elevating member successively to elevate the body.
5. The combination with a truck, and a dump body movable relative thereto, of a rear elevating member pivotally connected to the body and truck, an extensible front elevating member pivotally connected to the truck, a lever connecting said front elevat ing member to the body, an intermediate elevating member pivotally connected to-the body, means for anchoring said interme diate member to the truck, means for limiting the upward movement of the body, link connections between the lever and the intermediate elevating member, said connections being pivotally and slidably connected to said intermediate member, and a thrust member connected to the links.
6. The combination with a truck and a dump body movable relative thereto, of rear supporting members pivotally connected at their ends to the truck and body, from supporting members pivotally connected to the truck, levers connected to the front supporting members and to the body, a thrust member, an inclined guide along which said thrust member is adapted to travel relative to the truck. links connecting the levers to the thrust member, supplemental hoisting members pivotally and slidably connected to the thrust member at its point of connection with the links, a pivotal connection between the supplemental hoisting members and the body and flexible connections between the supplemental hoist members and the front supporting members.
7. The combination with a truck and a body movably mounted relative thereto, of
levers pivotally connected to one end portion of the body, front supporting members pivotally connected to the truck and to the levers, rear supporting members pivotally connected to the truck and to the body, thrust members movable relative to the truck, links connecting said thrust members to the levers, supplemental hoisting members pivotally and slidably connected to the thrust members at their points of connection with the links pivotal connection between said supplemental hoisting members and the body, and flexible connections between the supplemental hoist members and the lower portions of the front supporting members.
