Abstract
Abstract A support is rotatably mounted within a housing one side of which is open. A plurality of propelling arms are each swingably mounted by the support and are resiliently biased in one direction. The support is rotated during operation to cause the arms to be alternately cocked and released to propel material onto a suitable surface. Feed means is provided for feeding material to the propelling arms and the device is adjustable both in elevation and azimuth. In addition, a moveable framework is provided which enables the applicator device to be adjusted in both vertical and horizontal directions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A material applicator device comprising a substantially semicircular housing having a discharge opening, a support rotatably mounted within at least a portion of said housing, a plurality of propelling arms each of which is pivotally and swingably mounted on said support, means resiliently biasing each of said arms in one direction, feed means for feeding material to said arms and said housing, each of said arms engaging said housing upon rotation of said support such that the arms are caused to swing in a direction opposite to that in which the arms are resiliently biased, said housing including an arcuate release portion of enlarged radius for releasing each of said arms such that upon release the arms are forcibly swung by the associated resilient biasing means so as to propel material onto a suitable surface.
Claim 2
Dependent Claim
135 words
A material applicator device comprising a substantially semicircular housing having a discharge opening, a support rotatably mounted within at least a portion of said housing, a plurality of propelling arms each of which is pivotally and swingably mounted on said support, means resiliently biasing each of said arms in one direction, feed means for feeding material to said arms and said housing, each of said arms engaging said housing upon rotation of said support such that the arms are caused to swing in a direction opposite to that in which the arms are resiliently biased, said housing including an arcuate release portion of enlarged radius for releasing each of said arms such that upon release the arms are forcibly swung by the associated resilient biasing means so as to propel material onto a suitable surface.
Claim 3
Dependent Claim
24 words
A device as defined in claim 1, including limit stop means for limiting the swinging movement of each of said arms in one direction.
Claim 4
Dependent Claim
29 words
A device as defined in claim 1, wherein said means resiliently biasing each of said arms in one direction comprises spring means in engagement with each of said arms.
Claim 5
Dependent Claim
23 words
A device as defined in claim 1, including adjustable mounting means which provides adjustment of said applicator device both in elevation and azimuth.
Claim 6
Dependent Claim
148 words
A material applicator device comprising a substantially semi-circular housing having a discharge opening, a support rotatably mounted within at least a portion of said housing, a plurality of propelling arms each of which is pivotally and swingably mounted on said support, means resiliently biasing each of said arms in one direction and feed means for feeding material to said arms and said housing, said feed means including a feed hopper and conveyor means in communication with said feed hopper for conveying material from said feed hopper to said arms and said housing, a framework having means for supporting and adjusting said applicator device, feed hopper and conveyor means in both vertical and horizontal directions, said framework including a support means which is movable vertically relative to the framework, and a carriage means being supported on said support means and being movable in a horizontal direction with respect thereto.
Claim 7
Dependent Claim
148 words
A material applicator device comprising a substantially semi-circular housing having a discharge opening, a support rotatably mounted within at least a portion of said housing, a plurality of propelling arms each of which is pivotally and swingably mounted on said support, means resiliently biasing each of said arms in one direction and feed means for feeding material to said arms and said housing, said feed means including a feed hopper and conveyor means in communication with said feed hopper for conveying material from said feed hopper to said arms and said housing, a framework having means for supporting and adjusting said applicator device, feed hopper and conveyor means in both vertical and horizontal directions, said framework including a support means which is movable vertically relative to the framework, and a carriage means being supported on said support means and being movable in a horizontal direction with respect thereto.
