Application No. 09/400,932
It is an object of Metzger's invention to provide an improved means by which a
construction worker on a hose gang is able to hold, control and manipulate a concrete
delivery hose. In Figures 1 and 2, Metzger teaches a bar guide for a concrete delivery
hose which includes a flexible connecting means between a clamp which attaches
to the hose and the bar handle. Operation of the invention is shown in Figure 4 wherein
concrete from a hopper 100 is to be delivered through hose 101 to a building form 102
which is at a distance from the hopper. Workers 103 and 104 are shown on a working
surface 105. The bar hose guides, such as shown in Figures 1 and 2 are affixed to the
hose at the end of the hose distant from the concrete source and proximate the
construction site location at which the concrete is to be delivered. The concrete being
poured is shown flowing from the delivery end of the hose at 106. A gravity fed system
is shown although pumped or other systems which force concrete through the hose are
also known. The bar guides thus shown in Figure 4 include the clamp means 200 for
securing connection around the outer diameter of the hose, flexible interconnection
means 201 between the clamp and the stem 202 of the bar, and bar crossing means
203 which are held at each end by the two hands of the construction workers. The bar
guides are thus manipulated in coordination by the work gang to guide the delivery end
of the hose to the form which is to receive the concrete. In this manner it can be seen
that the guide of the invention allows the workers to be separated a predetermined
distance from each other and from the hose. The workers are comfortably spaced and
