H. s. PA LM BODY ELEVATING MECHANISM FOR DUMPING WAGONS OR THE LIKE Filed Feb. 17, 1939 Mama 5. alm
NVENTQR ATTORNEYS Patented June 4, 1940 UNITED STATES BODY PATENT OFFICE ELEVATING MECHANISM FOR DUMP;
ING WAGONS on THE LIKE 3 Claims.
My invention relates to body'elevating mechanism fordumping wagons and the like, and
more particularly it consists in certain new improvements to the elevating lever mechanism thereof, whereby its construction is simplified, its elevating height increased, andthe body elevating stress reduced, all as more fully set forth and described hereinafter in'connection with the accompanying drawing, and the novel features being partially indicated in'dash lines.
Fig. 2 is a corresponding sectional side elevation showing the body lowered and resting on the supporting frame, and my elevating lever mechanism closely folded within the side walls of said supporting frame.
The drawing shows one side portion of the movable body 5, and one side wall 6 of the body supporting frame having a guide-Way thereon, the like opposite side walls being connected by end walls 8 and 9.
The body elevating arms are, as usual, arranged in pairs of like members spaced to fold within the frame side walls and are mounted on the latter and connected to side portions of the body, and in describing the arms at one side shown in the drawing, it is to be understood that like arms on the opposite side, not seen, cooperate in elevating the body.
As seen in the drawing, I0 indicates a main body elevating arm, pivotally connected at H to a rear portion of frame wall 6, with its opposite end in lifting engagement with a forward portion of the body 5, preferably, as shown, by means of a link arm l2, pivoted at l3 to the end of arm l0, and at M to the body 5, such link arm connection providing for necessary relative body adjustment to said main arm l0, and increasing the body elevating action of the latter as link arm I2 is swung on its pivotal connections.
A supplemental body elevating arm is indicated at l5, pivotally connected at IE to a rear portion of the body 5, and intermediately, at H, to main arm I0, with an arm portion l8 extending beyond such pivotal connection.
To initially elevate the front end of the body 5, I
the drawing shows a primary operating lever preferably comprising a section 20 having its end 2| slidably engaging in guide-way l, and a telescoping extension 22 thereof having its end pivotally connected to main frame I0, preferably shown as coincident with the pivotal connection ll of the main and supplemental elevating arms Ill and 5.
A supplemental operating lever 25 is shown as having its end 26 slidably engaging in guide way I rearward of the end 2| of'the primary operating rod, and its-opposite end pivotally connected at 27 to main arm Illv at a point spaced from pivotal connection H and nearer the frame pivotal connection ll of said arm Ill. And an intermediately hinged link arm 28 is shown with one end pivotally connected at 29 to the end of extension |8 of the supplemental elevating arm l5, and its other end pivotally connected at 30 at an intermediate 'point in the length of supplementary operating lever 25. This supplemental operating lever 25 acts on main arm ill to further swing the latter on its pivotal frame connection II and to swing arm IS on itspivotal connection I1 to jointly elevate the rear and further elevate the front end of the body 5.
Cross bracing between the like arms of the several pairs to insure their cooperative equal movements is shown by cross-section lines on certain of the pivotal connections to indicate transverse tie rods acting also as pivot pins for the connected members.
The end 2| of primary operating lever 20 is shown with an anti-friction roller engaging in slide way 1 and the pintle 23 of the latter is crosssectioned to indicate a tie rod connection to its like end of the opposite side lever. End 26 of lever 25, also slidably engaged in guide way I, is shown at 24 as forked to engage tie rod 23; and, as seen in Fig. 2, end 2| has an independent movement in guide way 1 before its tie rod 23 engages the fork 24 in the end 26 of lever 25, after which they move jointly in guide way I. And such independent and joint guide-way movements of the ends 2| and 26 may be secured by any suitable operating means acting to move end 2| rearwardly, a suitable gear and rack mechanism being shown in my prior Patent No- 1,264,432 of April 30, 1918, which also shows means for slidably engaging the end 25 of lever 25 in guide way I, not herein indicated.
The primary operating lever 20--22 has an advantageous leverage due to its arm pivotal connection I1 being at a distance from the frame pivotal connection II of the latter, and the independent guide-way movement of its end 2| causes only the front end of the body 5 to be elevated, thus reducing the stress of such initial elevation and the force required to effect it, and such initial elevation determines the delivery incline or pitch given to the body. And during the joint guide-way movement of the ends 2! and 26 of both operating levers 2ll--22 and 25, the latter with its increased lifting action on arm 10, due to its pivotal connection 2'! being closer to pivotal connection ll, swings arm H] to an increased height, made possible by the free extension of telescoping extension 22 of said primary operating lever. The hinged link arm 28 is opened by movement of lever 25 and acts on the end l8 of arm IE to swing .the latter on its pivotal connection I! to main arm It so as to elevate the rear of body 5 while main arm Ill further elevates the front end so that said body is elevated with the pitch given by the initial *elevating action of lever 2022. And due to the increased movement of main arm H] by supplemental operating lever 25, link connection 12 between said arm end and the body, and to the pivotal connections ll, 29 and 30 being on arms elevated above the supporting frame, a greatly increased body elevation is secured, with a closely compacted folded relation of said arms within the height limits of the supporting frame Walls as clearly seen in Fig. 2.
When mere tilting'dump elevation of the body is desired either pivot connection 29 or 30 may be arranged for disconnection, in which casesupplemental arm ['5 does not act, andmain arm l only acts to raise the front end of the body as indicated in dash line in Fig. 1.
From the foregoing description it is believed the nature and advantages of my improved elevating lever mechanism will be readily understood, and the particular embodiment shown and described may of course be modified within the spirit of my invention as defined in the following claims.
What I claim is:
1. The combination with an elevating body and a supporting frame provided with a horizontal guide-way, of a main elevating arm pivotally connected to the rear portion of said frame and in lifting engagement with the forward portion of the body, a supplemental elevating arm for the rear portion of the body intermediately pivoted to said main arm, and primary and supplemental operating levers; separately pivoted to said main arm at different distances from the" 2. In the construction set forth in claim 1, said primary operating lever having telescoping parts, in combination with a folding-link connecting said supplemental operating lever to the end of said supplemental elevating arm, extending beyond its intermediate pivotal connection to said mainarm.
3. The combination with an elevating body and a supporting frame provided with a horizontal" guide-way, of an elevating arm pivotally connected to the rear portion of said frame and in lifting engagement with the forward: portion-of the body, a primary operating lever of telescoping parts, and a supplementary operating lever of fixed length, respectively separately pivoted to said elevating arm at difierent distances from the frame connection of the latter and having their free ends separately and jointly movable in said frame guide-way; said primary lever being operable on said elevating arm to initially lift the forward portion of the body during its separate movement in said guide-way and to idly elongate its telescoping parts during its joint guide-way movement with said supplemenfurther raise the forward portion of the body.
