TIP-VEHICLE.

Application filed December 23, 1920.

To all whom it may concern Be it known that we, WALTER BARNETT and JAMES FLORENDINE, subjects of the King of Great Britain, residing at Rugby, Warwickshire, England, have invented certain new and useful Improvements in Tip-Vehicles, of which the following is a specification.

Tip carts, tip wagons and like vehicles are commonly constructed so that the base of the tipping body is supported upon the framework and passes above the road wheel axle, and when tipped to discharge the load the body turns on an axis coincident with or somewhat above the road wheel axle, and various means have been proposed to bring about the tipping of the body about such an axis, as for instance it has been suggested that chains should be connected to the body or to a bracket thereon and wound .on a

drum which is fixed on a shaft and provided a high load line, and yet permit of the body being tilted to a sufficient angle before striking the ground, it has been suggested that the body should be carried at a lower eleva- 1 tion from the ground, by means of pivots extending from each side of the body engaging with links extending from the wheelsupported framework, all so arranged that upon and during the tilting of the body the latter assisted by the shifting of the load toward the tipping end of the vehicle would cause the said body to be gradually raised simultaneously with the tipping motion.

Now the object of the present invention is to provide means whereby the body shall be capable of being tilted to an amply suflicient angle for discharge purposes without striking the ground in a vehicle in which the said body is not only mounted so that its base or load line is at a low elevation, but also.

where the said body extends for such a distance on either side of its tilting axis as will permit of thesaid body having the desired capacity;

According to this invention the tipping body of the tip cart, tip wagon or like ve Specification of Letters Patent.

Patented July 5, 1921.

Serial No. 432,716.

hicle, hereinafter termed tip cart, is supported upon pivots, studs or rollers, hereinafter termed rollers, extending from said tipping body into guide members carried by the framework of the vehicle, and the said guide members extend upwardly from said framework of said vehicle; mechanical means, such for instance as a flexible connection connected to some hoisting appliance, is provided whereby said pivots carrying said body are raised upwardly for a distance to raise the said tipping body substantially vertically from the ground, and means are provided whereby upon the continued operation of said mechanical lifting means said body is caused to turn about the axis of its pivots to the necessary tipping angle to discharge its contents.

The reversal of motion of the lifting means by which the body was raised substantially vertically, may and generally does operate to cause the body to assume its horizontal position and to lower said body to its normal level.

' Figures 1 and 2 show a construction in side elevation and end view of a tip cart in which the tipping axis of the body is parallel to the road wheel axis, Fig. 3 is a horizontal section of one of the guide members showing the pivots or rollers in their respectivepositions, Fig. 4- is a side elevation of the tip cart in its raised and tilted positions, the tilted position being shown in dotted outline, and Fig. 5 shows another form of construction according to this invention, showing the tip cart in a semi-raised and semi-tipped position, the latter position being indicated by dotted lines.

Now referring to Figs. 1 to 4 and according to this invention the road wheels 1, which need not necessarily be of large diameter, are mounted on the framework 2 of the vehicle upon stud axles 3 extending exteriorly from the side members of the framework 2. The body 4: is located within and between the side members, the base 5 of the body 4. being very near the surface of the ground when in its normal position for loading and usually located below the axis 3 of the road wheels 1.

On each side of the vehicle two parallel guide members? at a distance apart, extend upward from the side members of the framework 2, the members 7 being usually inclined rearwardly, the upper ends 8 of the members 7 being given a rearward curve,

said forward revoluble shaft 12 is fitted and the body 4 of the vehicle 011 each side is fitted with two guide rollers 9, Fig. 3, mounted on stud axles 10 on the said body 4, the guide rollers 9 fitting between parallel guide members 6, and in the normal loading posi tion the lower guide roller 9 on each side of the body rests in the base of the guide members 6, and the upper roller 11 on each side of thebody, being located at a higher elevation between the guide members 7 holds the body 4 in the normal loading position.

A forward revoluble shaft 12 ismounted in bearings on the framework 2 of the vehicle forward of the body 4 and extending transversely of the said framework 2, and

with'a hoisting gear consisting of flexible connections 13 extending from the r'evoluble shaft 12 over guide pulleys 14 and 14*carried from the framework of the vehicle, while the opposite ends of the flexible connections are attached to a yoke 10" extending from the stud axle 10 on each 'side of the body 4 of the vehicle, so that when the winch shaft 12 is turned the body 4 of the vehicle will be raised vertically during the first part of its motion to distance the base of the body from the ground as shown in 7 full lines, Fig. 4, and during the further part of its motion the upper guide rollers 11011 the body 4 will enter the rearwardly curved parts of the guide members 7 and cause the tilting of the body to the necessary angle, shown for instance indotted I at which its base 5 is but a short distance from the ground.

In constructing the apparatus, oneor both of the rearwardly inclined guide members 6 are extended in height so as to carry the I pulleys 14 over which the flexible connections 13 pass for the raising of the body 4, and the upper ends of the upwardly extending guide members 6 may be connected by a bar or the like 15, Fig. 2, extending transversely of the vehicle, which bar 15.

may constitute a stop for limiting the tilting motion of the body 4.

I The winch shaft 12 is usually fitted with a ratchet and pawl device 16, Fig. 1, so that the shaft 12 is prevented having'motion whenleft free during the time the body 4 is in its tipping position, and conveniently the flexible connections 13 passing from the shaft 12 extend beneath pulleys 14 mounted on the framework 2 of the vehicle, and then extend upward and over thepulleys 14carried on the upper extensions of the guide members 6.

It-will now be understood that with a vehicle thus constructed the base 5 of the body in its loading position as at Fig. 1 can be arranged at a very-short distance from the ground, and consequently the upper edges of the sides of the body can be at such a low elevation that the vehicle can be loaded 4 has been raised'during'the tipping opera- ,7

tion to a requisite elevation shown in full lines Fig. 5, contact with rearward extensions 17 of the side members of the'framework 2 of the vehicle, and thus facilitate and assist the tilting operation;

The rearward extensions '17 .may'convenientlyconsist of springs as shown.

The framework on either side of. the ve-'. hicle may be extended below the 'studa-xles carrying the wheels, and a bar '18 can have its ends fixed thereto and extend beneath the body of the vehicle.

It will be readily understood that the vehicle may be arranged so thatthe tipping axis of the body is parallel with the axis of the road wheels for end tipping, or the tip-' ping axis may be transverse to the axis of the roadwheels for side tipping. 7

Furthermore screw or' lever action lifting gear for raising the body would'be obvious equivalents for the winch gear-described.

lVhat we claim as our invention and desire to secure by Letters Patentisz 1.. Intip carts and like ,vehicles;the combination of a framework roadwheels carried by said framework, guide 3 members fixed tosaid framework upon joppositesides thereof and extending upwardly therefrom, a cart body, rollers extending from opposite sides of saidbody to engage with said guide members and normally resting in the bases "of the guideways of said guide members,

means connected to said body whereby said bodyand sald rollers carrying said body can be raised upwardly in said guide members to distance said body substantially vertically from the ground, andmeans by which upon the continued lifting of said body by said mechanical lifting means said-body is caused to turn about the axis of its rollers to the necessary tipping angle to discharge its contents- I 7 r 2. In tip carts and like ehicles; the combination .of aframework', road wheels carried. by said framework, guide, members and a second guideway extending straight upwardly for a distance and then curved in the direction in which said body. is .to be tipped, a lower and an upper roller extending from each side of said body said lower roller to engage with said first guideway and normally resting at the base thereof to support said body and said upper roller engaging said second guideway in a position therein to maintain said body in its normal carrying position, mechanical means to raise said body to distance said body from the ground and to cause said upper rollers to pass into said curved portions of said second guideways to effect the tilting of said body to discharge the contents, and whereby upon said body being lowered by said mechanical means all said rollers enter the straight portions of said guideways to return said body to its normal position.

3. In tip carts and like vehicles; the combination of a cart body the base of which in its loading position is near the road, a

framework extending in front of said bodyand for a distance upon each side of same, a. lower extension on each side member of said framework, a bar connecting said lower extensions said bar passing beneath said J oody, stud axles on the exterior faces of said side extensions, road wheels mounted on said stud axles, a guide member .extendlng upwardly from each side member of said frame,

work each of said guide members having a first straight upwardly extending guideway and a second guideway ext-ending straight upwardly for a distance and then curved in the direction in which said body is to be tipped, a lower and an upper roller extending from each side of said body said lower roller to engage with said first guideway and normally resting at the base thereof to support said body and said upper roller engaging said second guideway in a position therein to maintain said body in its normal carrying position, a member extending rearwardly from and fixed to each side member of said framework, an exteriorly projecting striking pin fixed on each side of said cart body said side pins being located below said rearward extensions when said cart body is in its loading position and adapted to contact with said rearward extensions when said cart body is raised, and means to raise said cart body to distance same from the ground to cause said striking pins on said cart body to contact with said rearward extensions of said framework and to cause said upper rollers to pass into said curved portions of said second guideways to effect the tilting of said body and to lower said body to cause all the rollers to reenter the straight portions of said glllClBWiLyS to return said cart body to its normal loading position.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
