Application August 29, 1933, Serial No. 687,343
5 Claims. (CI. 298-11) This invention relates to dump bodies of that type used for handling coal, buildingV materials, etc., and adapted to be elevated to different heights and angles to meet the conditions governing the delivery of the loa-d.
One of the objects is to provide screw operated means for actuating the hoist mechanism, it being possible, by the shifting of a portion of the mechanism, to convert it quickly from a low dump to a. high dump and vice versa.
A further object. is to simplify and otherwise improve upon the construction of the body lifting mechanism.
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 changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings:
Figure 1 is a side elevation showing the body and cooperating parts in their normal positions.
Figure 2 is a similar view showing the supplemental thrust arms elevated to active positions.
Figure 3 is a side elevation showing the maximum low dumping position of the body while the supplemental thrust arms are inactive.
Figure 4 is a view like Figure 3 showing the maximum high dump position of the body with the supplemental thrust arms in use.
Figure 5 is a perspective view of the lifting device provided for the supplemental thrust arms.
Figure 6 is a perspective view of one of the rear supporting links.
Referring to the gures by characters of reference, 1 designates the chassis of a vehicle provided with a stationary frame 2 in which one or more screws 3 are extended longitudinally and adapted to be rotated by any suitable mechanism. These screws can have any desired number of threads which engage a cross head 4 slidable in frame 2.
A tiltable frame 5 is pivotally connected at 6 to frame 2 and normally resting thereon is the body 7.
Pivotally connected at 8 to the cross head 4 are the lower ends of the main thrust arms 9 the upper ends of which are pivoted at 10 to the hinged or tiltable frame 5.
Supporting links 11 are also attached to frame 5 at 10 and to the body '7 at l2. Each of these links'has a socket member 13 depending therefrom near its pivotal point 12.
A cross shaft 14 is arranged in frame 5 and 60 has rollers 15 adapted to travel within the channeled sides of said frame. This shaft is joined to arms 9 by connecting links 16. Front supporting links 17 extend from shaft 14 and are attached to body '7 at 1s. 65
Normally the parts are arranged as in Figure 1. By revolving the screw or screws 3 the cross head is fed rearwardly and causes arms 9 to thrust upwardly on frame 5. Said frame will thus be tilted and as links 16 `are moved rearwardly by the motion of arms 9 about pivot 10, the links 1'7 will exert an upthrust against body 7 and tilt it on frame 5 as shown. Thus a low abrupt dumping action can be effected.
Should a high dump be desired, the operator, before moving the cross head from the position shown in Figure 1, swings lever 22 tc rotate shaft 21 and move ngers 20 upwardly. These ngers thus will raise the arms 19 as in Figure 2. Consequently, when the cross head is moved rearwardly the rear ends of arms 19 will be guided into sockets 13. As a result of this action both arms 9 and 19 will be brought into action, arms 9 thrusting upwardly against and tilting frame 5 to raise one end of the body as in Figure 3 while arms 19 thrust upwardly against links 11 and raise the other end of the body of frame 5. This brings the body substantially to the position shown in Figure 4.
What is claimed is:
1. The combination with connected stationary and hinged frames, a body on the hinged frame, of front and rear supporting links connecting the body movably to the hinged frame, connected main and supplemental thrust arms, means for moving said arms along the stationary frame, a pivotal connection between the front thrust arms and the hinged frame, link connections between the front thrust arms and the front links, and means for connecting the rear thrust arms detachably to the rear supporting links.
2. The combination with connected stationary and hinged frames, a body on the hinged frame, of front and rear supporting links connecting the llO body movably to the hinged frame, connected main and supplemental thrust arms, means for moving said arms along the stationary frame, a pivotal connection between the front thrust arms and the hinged frame, link connections between the front thrust arms and the front links, socket members on the rear supporting links, and means for guiding the rear thrust arms into said socket members. 1 4f 3. The combination with connected stationary and hinged frames, a body on the hinged frame, of front and rear supporting links connecting the body movably to the hinged frame, connected main and supplemental thrust arms, means for moving said arms along the stationary frame, a
pivotal connection between the frontthrust arms frame, rear links connecting the body and hinged frame, connected front and rear thrust arms, a shifting link connection between the front arms and the front links, said front arms being connected to the hinged frame, means on the rear links adapted to receive the rear thrust arms, and means for supporting the rear arms in either of two positions for engagement with or for movement pastthe said means, respectively, and additional :means for moving the thrust arms along the stationary frame.
' 5. The combination with connected stationary 'and hinged frames, a body on the hinged frame, of front and rear supporting links connecting the body movably to the hinged frame, connected main andsupplemental thrust arms, means for moving said arms along the stationary frame, a pivotal connection between the front thrust arms and the hinged frame, link connections between the front thrust arms and the front links, socket members on the rear supporting Y links, lifting iingers beneath the rear thrust arms, and means for actuating said iingers to raise said arms into position for engagement with the socket members.
