pingLoi-ries, of which the following is aspecification. I w I The invention relates to lorries having a tipping body and particularly to those 101;- ries of this kind the body of which is pivotally connected to levers which are swing-v ingly mounted on the underframe of the lorry and which body is adapted to be tipped, with respect to the said levers, by
means of a tipping device, and to'be lifted The object of the"invenat the same time; tion is to soimp'rove lorries ofthis" kind that they can be used like an ordinary end tipping lorry.
The drawings show an embodiment of the' subject-matter of the invention,
Fig. 1 is an elevation of the lorry with the body in travelling position,
Fig. 2 is the corresponding top view with the body removed, v Fig. 3 shows an elevation of the lorry with the body lifted and tipped and ina position with respect to a railway car such as toenable the material loaded to slide over from the motor lorry to said'car; further,
in an enlarged scale, 7
Fig. ,4: shows a section on line' 44- of Fig. 2, seen from tlieleft, V I
Fig; 5 a'section on line '55 of Fig, 4, and Fig. 6 a section on line 6--6 of Fig. 4. Referring now to these drawings, A de notes the two side girdersof theunderframe each of which has mounted on it a bracket a (Figs. 1to'3), atwo-armed lever B B being pivoted in each bracketa by means of coaxial. pins b The levers B B are arranged symmetrically with respect to'the vertical middle plane of'the lorry. To the free end of the arm B of the levers B B is hinged, by pinst the rear end ofside girders which form part of a frame c efixed' to the body C of the lorry sothat tlie'bodv can. be tipped, with respect to the leversf the frame 0 while the levers B in their turn rest upon angle pieces'a mounted on the rear, end of the side girders A.
B teeth 7. B about the axis of the pins 5 Thenin the travelling position, the body rests upon" the levers B B by means of cross beams of lifting 'ack'com risin' telesc'o ej sc rew' e l P g spindles "is attached to the"-front-wall oftlie" body C, this lifting ack-be ing disposed inthe vertical middle plane of'the'lorry. D D D designate the screw spindles (Fig. 8-)
and D the lifting nut which is"swin-gi'ngly fixedon'thebody C.
The spindle D rests upon a ball journaa cross beam F of the underfram e'by means of the hub of a spur wheel M. The bevel wheel E, is in mesh with two bevel wheel's G G the shaft 9 of which rests intwo bearings" 7. These bearings aremounted on'a casingf fixed to the cross beam On' the hubs g 9 of the bevel wheels G G are fixed a spur wheel H and'a spur wheel H respectively. The wheel His 'in'mesh with a spur wheel J and the 'wliee'lI I with aspuiwheel J The hubs i 'z' of the spur wheels J and J each rest in bearings f? closed by covers f The inner cylindrical surface of the hubs 2' and i is providedeachwith a rim of teeth '2' and i respectively. 7
In the bearings f f thereisfurther rotatably and shiftably mounted a coi'1pling shaft K whichpasses through the hubs i 2' and is coaxial with an intermediate shaft L igs. 1 and 3) forming a'connection to the shaft of the motor ofthe' lorry. The rear end of the shaftL forms a pinion L and extends into the coupling shaft K. .The'latter' carries" at its ends external rims of'teeth k 70 intended to be engaged by the'teeth 2' 2' of the wheel hubs if", i Furthenthe'inner cylindrical surface of the shaft K shows two rims of teeth Z0 k which are intended to be engaged bythe pinion L? of'the shaft L The distance apart of the rims'ofteethlfi, 70 is larger than thejwidth of the pinionL so that this pinion, with an intermediate position of the shaft K, will engage neither the teeth 72 nor the With the shaft K in this intermediate position, the teethwere out of engagement'with the teeth 2' and the teeth 70 with thefteeth 2' By shifting the'coupling shaft K,' however, out of this position in the direction of arrow w (Fig. 5) the teethkcan be caused to engage the pinion" L and the teeth k to engage the teeth'z' so that the body C can be tipped by the motor of the lorry about the axis of the pins Y the shaftK is performed by means of a lever Z (see particularly Fig. 4) mounted on the casing P which lever embraces the shaft K with a circular portion and engages in an annular groove of the shaft by pins Z The spur wheel M, mounted on the shaft 6 of the bevel wheel E, engages in two spur wheels N (Fig. 4) which are disposed symmetrically with respect to the vertical middle plane of the lorry. Each of these spur wheels N is rotatably mounted on the hub p of a spur wheel P which, in its turn, is mounted on'a journal p fixed on the cross beam F. The hub n of each spur wheel N u wardly extends through a bearing 47, which is supported by a plate 7 fixed on the cross beam F. The upper front faces of the hubs 91 p of the wheels N and P show coupling teeth n and 22 respectively. On each journal p there is further rotatably and shiftably .mounted a coupling member Q (see also Fig. 6) having corresponding coupling teeth g and acted upon by a spring one end of which rests on the coupling member Qwhile the other end bears against a disc g fixed by a nut f screwed on the journal 112 The spring 97 tends to hold the coupling member Q in a position such as to cause the coupling teeth to engagethe teeth a and p, the coupling member Q thus rigidly connecting the spur wheel N to the spur wheel P. Fiach coupling member Q shows an annular groove q in which engage two pins 1 fixed to two fork levers R. The fork levers R of the two coupling members are fixed on a shaft 7' (see particularly Fig. 6) which rests in bearings f fixed on the plate 7' of the cross beam F. A hand lever R -fixed on the shaft 7 serves to oscillate the fork levers R in a manner such as to cause the coupling members Q to be shifted, against the action of the springs 9 along the journals p and the coupling teeth thus to come out of engagement with the coupling teeth a and 72 Onthe drivers cabin is provided a guide are 663 by means of which the hand lever B canbe locked in two positions (I and 11, Fig. 6) in which the teeth 9 ofthe coupling member Q are inor out of engagement with the teeth n and p. Y
A pawl f (Fig. 6) is pivotally mounted in eyes 7" on the plate 7, by means of a pin i said pawl having a projection f which is adapted to engage either above or below a projection r of one of the fork levers R, according to the position of the hand lever R The pawl f shows further an arm f against which abuts a projection c fixed to the front end of the body C, when the body takes the travellin position. Within the pawl i there is shiftably mounted a bolt f which is under the action of a spring i and abuts against the plate 7.
Each of the spur wheels P is in engagement with a spur wheel S (Fig. i) which is rigidly fixed on a screw spindle T. These screw spindles are rotatably but nonshiftably mounted on the underframe of the lorry, they pass each through a bearing t and rest, on the one hand, by a collar t upon the lower front face of the bearing 19, through the intermediary of a ball bearing t and, on the other hand, upon the hub s of the spur wheel S, by means of a nut s screwed on said spindles and fixed thereto by a pin 8 said hub 8 in its turn, resting upon the upper front face of the bearing The screw spindles T, T are held at their upper ends each in a bracket a" fixed on the drivers cabin and are engaged by female threads of a traverse U. The ends of this traverse U are connected each by a rod V with the free end of the arm B of the respective doublelever B B Owing to this arrangement it is possible, by means of the motor of the lorry, not only to operate the lifting jack D, D D D but also, with the coupling members Q thrown in, to so shift the traverse U on the screw spindles T that, through the intermediary of the rods V and the levers B B swinging about the axis of the pivots b the body C is simultaneously lifted when it is tipped into the discharging position,
The body C shows a downwardly tiltable rear well (Figs. 1 and 3) to which are fixed two side plates guided onthe side walls of the body. An arm .V (Figs. 1 to 3) is rigidly connected to the rear end of the body C and has hinged onit a rod 10 the other end of which is connected by a pin w to an arm to pivotally mounted on one of the pivots 6 To the pin 10 is attached a rod to hinged to a rod to. The latter is guided in a bearing 10 fixed to the underframe of the lorry, and has a slot L07 through which projects the above-described lever Z operating the coupling shaft K. The system of rods W 10 L03, w w 10 is capable to so adjust the lever Z, when the body C is in its extreme tipping positions or in travellingeposition, that, the coupling shaft K comes to be thrown out.
In case the body G has to be tipped into the discharging position as an ordinary end tipping lorry, the hand lever R has to be brought into the position II (Fig. 6) and to be locked in this position. The coupling members Q are then out of engagement. Thereupon the coupling shaft K is shifted, by means of the lever Z from the middle position in the direction of arrow 13 (F ig. 5). With the motor running, the body C is now tipped about the axis of the pivots b Immediately after the beginning of this tipping movement the projection 0 comes to be lifted from the arm f of the pawl 7" which latter will thereupon be swung, by the spring-operated bolt f into a position such as to cause the projection 7' to engage under the projection r of the fork lever B. The hand lever B is thus hindered to be brought into position I so that the teeth g of the coupling members Q cannot engage the teeth 11 and p of the spur wheels N and P, while the body is tipping. During the tipping movement the body 0 so acts upon the lever Z, by means of the rod system W, w e0 10 'w, w", 107, that, with the extreme tipping position of the body 0, the coupling shaft comes to take again its middle position and thus to be thrown out of operation.
If the body C has to be lowered again into the travelling position, the coupling shaft K has to be shifted opposite to arrow at by means of the lever Z. lVhen the body attains the travelling position, the rod system W w throws the coupling shaft K out of operation by means of the lever At the same time the projection c shifts the pawl f into the position of Fig. 6 so that the fork lever B is released again by the latter.
If the body 0 has to be tipped and lifted up to the position of Fig. 3, for example, in order to directly transfer the loaded material from the motor lorry into another vehicle, a railway wagon for example, the hand lever'R has to be brought into position I. T he teeth 9 of the coupling members Q then are in mesh with the teeth a and p of the spur wheels N and P. If now the coupling shaft K is shifted in the direction of arrow 00, the body will be tipped about the axis of the pivot b and at the same time lifted by the members 6 M, N, Q, P, S, T, U, V, B B At the beginning of this tipping and lifting the projection 0 releasesthe pawl f so that the projection 7 of the latter engages over the projection r of the fork lever B in question. Thus the coupling members Q are secured against disengagement during tipping and lifting the body C. When this latter has reached its extrme tipping position, the coupling shaft K comes to be thrown out by the system W to 10 The transfer ring of the tipped and lifted body C is initiated, as in the first described case, by shifting the coupling shaft K in the direction opposite to arrow :10. When the body comes to reach again the travelling position, the coupling shaft is thrown out again as above described, and the fork lever R is released anew by the pawl 7".
