Abstract
Abstract This invention is a stinger control device for use with a moving apparatus for placing and form pouring of concrete. It is used with an apparatus having a supporting structure, a concrete distribution hopper and means to move and control same when in operation moving over concrete forms. The stinger control device of this invention is mounted on the concrete placing and form pouring apparatus, and in operation compacts the placed concrete in the form. More particularly, the stinger control device includes a probe extending downwardly from the hopper and has apparatus to position same within the form and vibrate same. There is a control to withdraw the probe automatically upon contact with the form or a foreign object therein or upon reaching a bulkhead within the form.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
In a moving apparatus for placing concrete and form pouring thereof having a supporting structure, distribution hopper means movably mounted thereon, powering means therefor, and control means therefor, said apparatus communicable with a concrete form having means to receive concrete from said hopper means and for said apparatus to traverse, in combination therein and therewith the stinger control device of this invention for compacting of placed concrete, comprising: a. a probe means mounted on said hopper means and having a probe extending therefrom, b. means operably connected to said probe means to vibrate said probe in operation, c. a lifting means operably connected to said probe means and operable to position said probe means in said form and withdraw same, and d. probe control means operably connected to said probe means to automatically lift said probe upon contact of same with said concrete form upon movement of said apparatus for placing concrete in said form.
Claim 2
Dependent Claim
155 words
In a moving apparatus for placing concrete and form pouring thereof having a supporting structure, distribution hopper means movably mounted thereon, powering means therefor, and control means therefor, said apparatus communicable with a concrete form having means to receive concrete from said hopper means and for said apparatus to traverse, in combination therein and therewith the stinger control device of this invention for compacting of placed concrete, comprising: a. a probe means mounted on said hopper means and having a probe extending therefrom, b. means operably connected to said probe means to vibrate said probe in operation, c. a lifting means operably connected to said probe means and operable to position said probe means in said form and withdraw same, and d. probe control means operably connected to said probe means to automatically lift said probe upon contact of same with said concrete form upon movement of said apparatus for placing concrete in said form.
Claim 3
Dependent Claim
109 words
A stinger control device as described in claim 1, wherein: a. said probe means is mounted on said hopper means over the upper opening thereof, b. said probe means has side members adapted to hold said probe and guide same in vertical movement, c. said probe means has said lifting means operable to raise and lower said probe means vertically, d. said lifting means has a cable means and a hydraulic cylinder means in combination attached to said probe means, and e. said lifting means is operable by said control means of said probe means and operable by said powering means of said concrete placing and form pouring apparatus.
Claim 4
Dependent Claim
107 words
A stinger control device as described in claim 2, wherein: a. said probe means has a plurality of probes extending downward therefrom and held generally vertical with said probes in operation extending through said hopper means with ends thereof extending into said form, b. said probe means has a vibrating means which in operation vibrates said probes and same being controlled by said probe control means, and c. said probe means has a beam member held by said lifting means and said side members of said probe means and has a resilient vibration isolating support attached thereto supporting said probes, said vibrator means and rigidity adjusting means.
Claim 5
Dependent Claim
122 words
A stinger control device as described in claim 1, wherein: a. said probe control means is normally automatically operable to position said probes in said forms and vibrate same, withdraw sAid probes from said forms upon reaching the end portions thereof, and withdraw said probes from said forms upon reaching any obstructions therein, b. said probe control means is operable to insert and withdraw said probes upon command by the operator of said concrete placing and form pouring apparatus, and c. said probe control means is coupled to operate with said powering means and said control means of said concrete placing and form pouring apparatus in the normally forward motion thereof and to suspend temporarily said motion upon raising said probe means.
