Abstract
Abstract Conventional earth moving machines for dredging and scraping ponds or bogs are made amphibious, so as to enable them to move over water as well as over mud, by means of two detachable water-tight enclosures of tubular cross-section, placed on either side of the machine, those enclosures having provision for temporarily connecting them to the sides of the machines.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
Apparatus for making amphibious a dry-land earth moving machine which is inherently incapable of supporting itself on water, said apparatus comprising at least two tubular, water-tight elements adapted to be positioned on either side of said machine; detachable coupling means between said machine and each of said tubular elements; and means for controlling the elevation of said elements relative to the machine, said elements being constructed to be of substantially unchanging interior volume and to make the machine capable of supporting itself on water, said detachable coupling means comprising substantially vertical ears protruding from the elements toward the machine and mating with substantially vertical ears protruding from the machine toward the elements and removable pins for joining the ears for pivotal movement of the elements about substantially horizontal axes defined by the pins.
Claim 2
Dependent Claim
133 words
Apparatus for making amphibious a dry-land earth moving machine which is inherently incapable of supporting itself on water, said apparatus comprising at least two tubular, water-tight elements adapted to be positioned on either side of said machine; detachable coupling means between said machine and each of said tubular elements; and means for controlling the elevation of said elements relative to the machine, said elements being constructed to be of substantially unchanging interior volume and to make the machine capable of supporting itself on water, said detachable coupling means comprising substantially vertical ears protruding from the elements toward the machine and mating with substantially vertical ears protruding from the machine toward the elements and removable pins for joining the ears for pivotal movement of the elements about substantially horizontal axes defined by the pins.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1, wherein the elements are of welded, substantially semi-cylindrical sheet metal sections with sloping end faces and are given internal rigidity by crisscrossing channels.
Claim 4
Dependent Claim
37 words
The apparatus of claim 1 wherein each ear protruding from the machine is engaged in a recess between a pair of ears protruding from the tubular element, and each pin extends through all three of said ears.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1 wherein the ears protruding from the elements are attached to the respective elements along a channel member extending longitudinally of the element.
Claim 6
Dependent Claim
35 words
The apparatus of claim 1 wherein the elevation controlling means includes a plurality of telescoping arms, each arm being attached at one end to the machine and at the other end to a tubular element.
Claim 7
Dependent Claim
26 words
The apparatus of claim 5 wherein each telescoping arm is attached to the element by means of a protrusion from the upper surface of the element.
Claim 8
Dependent Claim
13 words
The apparatus of claim 5, wherein said arms are operated from said machine.
