APPARATUSFOR TREATING CONCRETE AND LIKE PLASTIC MATERIALS f A -mmwqww C. JACKSON Filed Sept. 6, 1932 A TTORNE YS INVENTOR yPatented eb. 20, 1934 UNITED STATES APPARATUS FOR TREATING CONCRETE AND LIKE PLASTIC MATERIALS Corwill Jackson, Ludington, Mich.
Application September 6, 1932. Serial No.` 631,806
10 Claims.
The main objects of this invention are:
First, to provide an apparatus for treating concrete and like materials, for example, the placing of concrete in walls, dams and various other situations.
Second, to provide an apparatus for treating or placing concrete or-like plastic materials which greatly facilitates placing thereof in positions difficult of access for placing by usual tampng methods.
Third, to provide an apparatus for treating and placing concrete which enables the placing of concrete of such low water content as would be diiilcult or impossible to place by the usual tamping methods.
Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is dened in the claims.
A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing, in which:
Fig. 1 is a fragmentary view illustrating the manner of using my improved apparatus, a fragment of a wall being shown for this purpose.
Fig. 2 is an enlarged fragmentary view of my apparatus partially in longitudinal section.
Fig. 3 is an inverted view.
In the accompanying drawing 1 represents a Wall or like form and 2 a body of concrete therein. My device or apparatus in the commercial embodiment illustrated comprises a housing 3 preferably cylindrical and having a downwardly tapered portion 4 at. its lower end terminating in the crossed or angularly disposed blades .or fins 5. This housing is adapted as a motor housing, an electric motor being indicated at 6.
The shaft '7 of this motor is disposed vertically and ls provided with an unbalancing weight 8 so that the motor constitutes a vibrating unit disposed within and entirely housed by the hous-k ing, which is closed so that it may be introduced or submerged in the body of concrete. The rodlike handle 9 is tubular and constitutes a conduit for the electric cable 10 for supplying current to the motor. The handle is resiliently connected to the housing, the connection in the embodiment illustrated being in the form of a tapered tubular coupling 1l. The lower end of this coupling is sleeved and clamped upon the neck 12 on the upper end of the housing. This neck is shouldered so that the clamp 13 binds the coupling member firmly to the neck.
The lower end of the handle is outwardly flared at 14 to receive the upper end of the coupling member, this coupling member being expanded and clamped into the end of the handle by means of the annular wedge 15 which is arranged upon the reduced stem portion 16 of the plug 18. The nut 19 is threaded' upon the lower end of this 6I reduced portion to forcethe wedge upwardly and into clamping engagement with the coupling member. The coupling member is of rubber or a suitable fabrication containing rubber so that it acts as a flexible resilient connection for the 66 handle to the housing, thereby relieving the operator of the vibrations'which would otherwise be imparted to the handle. At the same time the connection is sufliciently stiff or rigid so that the vibrating unit is held in approximately axial 'l alinement with the handle and may be freely manipulated thereby.
In use the body of cement is placed in the form or other position and the housing pushed or allowed to sink into the body of concrete or I6 other plastic mass. High frequency vibrations are imparted to the mass which effectively settles and compacts it into place. The flns or blades 5 tend to overcome the tendency for the housing to rotate, thereby rendering the device easier to operate. These ilns may be variously placed but I preferably locate them on the lower end of the housing, as illustrated. The hous` ing is closed so that water cannot reach the motor. In use the concrete or body of plastic material being treated constitutes a cooling medium for the motor.
The handle is preferably of considerable length as one of the advantages of the apparatus is that it may be used for the treating of concrete in situ at points that are inaccessible for ordinary placing operations. Further, the apparatus is particularly well adapted for the placing of mixtures having such low water content as is commonly regarded as unworkable, or in accordance with the method disclosed in my Patent No. 1,787,449, issued January 6, 1931.
The apparatus enables the very rapid and effective placing of concrete with comparatively little effort on the part of the operator.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
