Abstract
Abstract A refuse dumping apparatus having a pivotal and displaceable container in which a normally stored ejector blade can be disposed in the rearward path of the container and in which power means can move the container onto the rearwardly directed ejector blade causing impacted refuse to be pushed toward the rearward, dump opening of the refuse container; the ejector blade being fixed in either an operative or stored position; being raised by movement of the container and a cooperating cam means or by mechanical means such as a fluid motor, screw or the like; and the ejector blade being extensible by power means.

Claim 1
Independent Claim
193 words
Apparatus for handling and dumping refuse, comprising in combination: a support member having a forward and rear end; a refuse container displacably-supported on said support member; ejector blade means at the forward end of said support member exteriorly of said container; said ejector blade means including a support assembly including a displacable body member; means operatively connected to said body member for alternatively orienting the body member in a stored position outside the container or in a rearwardly-disposed operative position for introduction into the container upon forward movement of the container onto said body member; said refuse container on said support member having means for moving said container toward and away from said ejector body member, said refuse container having a rearwardly-opening portion through which refuse is dumped, said container having a forwardly-opening portion for receiving said body member therethrough when the container is moved onto the body member which is in an operative position; and power means operatively connected to said refuse container for moving said container onto said body member whereby said body member moves through said forwardly-opening portion of the container and impacted refuse is urged out of said container.
Claim 2
Dependent Claim
193 words
Apparatus for handling and dumping refuse, comprising in combination: a support member having a forward and rear end; a refuse container displacably-supported on said support member; ejector blade means at the forward end of said support member exteriorly of said container; said ejector blade means including a support assembly including a displacable body member; means operatively connected to said body member for alternatively orienting the body member in a stored position outside the container or in a rearwardly-disposed operative position for introduction into the container upon forward movement of the container onto said body member; said refuse container on said support member having means for moving said container toward and away from said ejector body member, said refuse container having a rearwardly-opening portion through which refuse is dumped, said container having a forwardly-opening portion for receiving said body member therethrough when the container is moved onto the body member which is in an operative position; and power means operatively connected to said refuse container for moving said container onto said body member whereby said body member moves through said forwardly-opening portion of the container and impacted refuse is urged out of said container.
Claim 3
Dependent Claim
188 words
Apparatus for handling and dumping refuse, comprising in combination: a support member having a forward and rear end; ejector blade means at the forward end of said support member; said ejector blade means including a support assembly for alternatively orienting the ejector blade means in a stored position or a rearwardly-disposed operative position; a refuse container on said support member having means permitting movement of said container toward and away from said ejector blade means, said refuse container having a rearwardly-opening portion through which refuse is dumped, said container having a forwardly-opening portion for receiving said ejector blade therethrough when the ejector blade means is in an operative position; and power means operatively connected to said refuse container for moving said container toward said ejector blade means and through said forwardly-opening portion of the container whereby impacted refuse is urged out of said container, said ejector blade means comprising an elongated body member extending transversely of said container, means pivoting said body member on a transverse axis of rotation, and lock means alternatively retaining said body member in a vertical-stored or horizontally-operative position relative to said support member.
Claim 4
Dependent Claim
188 words
Apparatus for handling and dumping refuse, comprising in combination: a support member having a forward and rear end; ejector blade means at the forward end of said support member; said ejector blade means including a support assembly for alternatively orienting the ejector blade means in a stored position or a rearwardly-disposed operative position; a refuse container on said support member having means permitting movement of said container toward and away from said ejector blade means, said refuse container having a rearwardly-opening portion through which refuse is dumped, said container having a forwardly-opening portion for receiving said ejector blade therethrough when the ejector blade means is in an operative position; and power means operatively connected to said refuse container for moving said container toward said ejector blade means and through said forwardly-opening portion of the container whereby impacted refuse is urged out of said container, said ejector blade means comprising an elongated body member extending transversely of said container, means pivoting said body member on a transverse axis of rotation, and lock means alternatively retaining said body member in a vertical-stored or horizontally-operative position relative to said support member.
Claim 5
Dependent Claim
47 words
The structure as claimed in claim 2 in which said container includes a cam track confronting the free end of said body member opposite means pivoting said body member, said body member including anti-friction means at said free end for facilitating raising and lowering the body member.
Claim 6
Dependent Claim
174 words
Apparatus for handling and dumping refuse, comprising in combination: a support member having a forward and rear end; ejector blade means at the forward end of said support member; said ejector blade means including a support assembly for alternatively orienting the ejector blade means in a stored position or a rearwardly-disposed operative position; a refuse container on said support member having means permitting movement of said container toward and away from said ejeCtor blade means, said refuse container having a rearwardly-opening portion through which refuse is dumped, said container having a forwardly-opening portion for receiving said ejector blade therethrough when the ejector blade means is in an operative position; and power means operatively connected to said refuse container for moving said container toward said ejector blade means and through said forwardly-opening portion of the container whereby impacted refuse is urged out of said container, said container including a hinged access panel depending over the forwardly-opening portion and displaceable inwardly by said ejector blade means when the container is moved onto said ejector blade means.
Claim 7
Dependent Claim
174 words
Apparatus for handling and dumping refuse, comprising in combination: a support member having a forward and rear end; ejector blade means at the forward end of said support member; said ejector blade means including a support assembly for alternatively orienting the ejector blade means in a stored position or a rearwardly-disposed operative position; a refuse container on said support member having means permitting movement of said container toward and away from said ejeCtor blade means, said refuse container having a rearwardly-opening portion through which refuse is dumped, said container having a forwardly-opening portion for receiving said ejector blade therethrough when the ejector blade means is in an operative position; and power means operatively connected to said refuse container for moving said container toward said ejector blade means and through said forwardly-opening portion of the container whereby impacted refuse is urged out of said container, said container including a hinged access panel depending over the forwardly-opening portion and displaceable inwardly by said ejector blade means when the container is moved onto said ejector blade means.
