Abstract

Abstract A dump cart is disclosed having a box removably mounted on an axle support and pulled by a drawbar. A latch is mounted on the drawbar to coact with a latch catch on the side of the box. The latch is biased by biasing means such as a spring located within the drawbar where it is protected from damage. The box can have two mounting positions with respect to the drawbar permitting alternate use of the front and back sides for dumping.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 167 words
A dump cart suitable for use with a garden or lawn tractor comprising: (a) a wheel assembly; (b) a body member having a front, back, and sides defining a cargo space; (c) means for removably mounting the body member on the wheel assembly in one of two mounting positions approximately 180 degrees relative to each other; (d) a drawbar, (e) means for connecting the drawbar to the wheel assembly to permit pulling and pushing of the cart; (f) a first latching means mounted on the drawbar; and (g) two second latching means, each mounted on the front and back of the body member and adapted to coact with the first latch means to releasably maintain the body member in a fixed position with respect to the drawbar; whereby the body member may be mounted in either mounting position and one of the second latching means will coact with the first latching means to releasably maintain the body member in a first position with respect to the drawbar.
Claim 2
Dependent Claim 167 words
A dump cart suitable for use with a garden or lawn tractor comprising: (a) a wheel assembly; (b) a body member having a front, back, and sides defining a cargo space; (c) means for removably mounting the body member on the wheel assembly in one of two mounting positions approximately 180 degrees relative to each other; (d) a drawbar, (e) means for connecting the drawbar to the wheel assembly to permit pulling and pushing of the cart; (f) a first latching means mounted on the drawbar; and (g) two second latching means, each mounted on the front and back of the body member and adapted to coact with the first latch means to releasably maintain the body member in a fixed position with respect to the drawbar; whereby the body member may be mounted in either mounting position and one of the second latching means will coact with the first latching means to releasably maintain the body member in a first position with respect to the drawbar.
Claim 3
Dependent Claim 24 words
The dump cart of claim 1 wherein the first latching means is a biased latch and each second latching means is a latch catch.
Claim 4
Dependent Claim 71 words
The dump cart of claim 1 wherein the means for removably mounting the member on the wheel assembly includes spaced substantially parallel channels disposed on the body member and a pair of substantially parallel flanges disposed on the wheel assembly which are adapted to be slidably received in the channels permitting the body member to be mounted on the wheel assembly in two positions approximately 180 degrees relative to each other.
Claim 5
Dependent Claim 244 words
A dump cart suitable for use with a garden or lawn tractor comprising: (a) an axle support; (b) a pair of substantially parallel flanges disposed on the axle support; (c) a body member having a front, back, and sides defining a cargo space; (d) a pair of substantially parallel channels disposed on the body member, each channel substantially parallel to the front and back side, the body member being removably mounted on the axle support with the flanges received in the channels; (e) a wheel set including an axle and spaced wheels mounted on the axle support; (f) a drawbar rotatably mounted on the axle comprising a channel member having sides and a bottom; (g) a first latch catch mounted on the front of the body member; (h) a latch mounted on the drawbar with one end of the latch pivotably mounted on the bottom of the channel member and the latch extends above the sides of the channel member where the other end of the latch defines an engagement surface adapted to coact with and retain the latch catch and a camming surface to coact with the latch catch to disengage the latch as the body member is moved toward the fixed position; and (i) a second latch catch mounted on the back of the body member whereby the body member may be mounted on the axle support in one of two positions with one of the latch catches coacting with the latch.
Claim 6
Dependent Claim 244 words
A dump cart suitable for use with a garden or lawn tractor comprising: (a) an axle support; (b) a pair of substantially parallel flanges disposed on the axle support; (c) a body member having a front, back, and sides defining a cargo space; (d) a pair of substantially parallel channels disposed on the body member, each channel substantially parallel to the front and back side, the body member being removably mounted on the axle support with the flanges received in the channels; (e) a wheel set including an axle and spaced wheels mounted on the axle support; (f) a drawbar rotatably mounted on the axle comprising a channel member having sides and a bottom; (g) a first latch catch mounted on the front of the body member; (h) a latch mounted on the drawbar with one end of the latch pivotably mounted on the bottom of the channel member and the latch extends above the sides of the channel member where the other end of the latch defines an engagement surface adapted to coact with and retain the latch catch and a camming surface to coact with the latch catch to disengage the latch as the body member is moved toward the fixed position; and (i) a second latch catch mounted on the back of the body member whereby the body member may be mounted on the axle support in one of two positions with one of the latch catches coacting with the latch.
Claim 7
Dependent Claim 187 words
A dump cart suitable for use with a garden or lawn tractor comprising: (a) an axle support; (b) a pair of substantially parallel flanges disposed on the axle support; (c) a body member having a front, back, and sides defining a cargo space; (d) a pair of substantially parallel channels disposed on the body member, each channel substantially parallel to the front and back side, the body member being removably mounted on the axle support with the flanges received in the channels; (e) a wheel set including an axle and spaced wheels mounted on the axle support; (f) a drawbar rotatably mounted on the axle; (g) a latch mounted on the drawbar; (h) a first latch catch mounted on the front of the body member, and adapted to coact with the latch to releasably maintain the body member in a fixed position with respect to the drawbar; and (i) a second latch catch mounted on the back of the body member whereby the body member may be mounted on the axle support in one of two positions with one of the latch catches coacting with the latch.
Claim 8
Dependent Claim 187 words
A dump cart suitable for use with a garden or lawn tractor comprising: (a) an axle support; (b) a pair of substantially parallel flanges disposed on the axle support; (c) a body member having a front, back, and sides defining a cargo space; (d) a pair of substantially parallel channels disposed on the body member, each channel substantially parallel to the front and back side, the body member being removably mounted on the axle support with the flanges received in the channels; (e) a wheel set including an axle and spaced wheels mounted on the axle support; (f) a drawbar rotatably mounted on the axle; (g) a latch mounted on the drawbar; (h) a first latch catch mounted on the front of the body member, and adapted to coact with the latch to releasably maintain the body member in a fixed position with respect to the drawbar; and (i) a second latch catch mounted on the back of the body member whereby the body member may be mounted on the axle support in one of two positions with one of the latch catches coacting with the latch.
