PAVING APPARATUS.
APPLICATION FILEDJULY25,1919.

UNITED STATES BOBERT C. STUBIBS,
OF DALLAS, TEXAS.
PAVING APPARATUS.
Application filed July 25,
To all whom it may concern Be it known that I, ROBERT C. STUBBs, a citizen of the United States of America, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Paving Apparatus, of which the following is a specification.
My invention relates to apparatus for use with a form of paving known as Vibrolithic paving which is a concrete paving, and the object is to provide a device or apparatus for transmitting the vibrations of a vibrating machine which is used in imparting vibrations to the mass of paving in the uncured condition for the purpose of solidifying the paving by driving out air and water and surplus moisture. The improved apparatus has been found to be highly eiiicient for transmitting the vibrations from the vibrating machine and also for gaging the concrete composition. By observing the amount of water or mortar which is being forced out of the concrete, an experienced person will know whether or not the required amount of mortar, or ingredients forming the mortar, have been mixed in the concrete. The advantages of the device are that the vibrations are efliciently transmitted to the mass of paving and the device serves as a gage. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.
Reference is had to theaccompanying drawings which form a part of this application.
The figure of drawing is a perspective View of the apparatus as it appears in action.
The apparatus consists of two or more stringers or longitudinal bars 1 and 2 which are preferably made of wood which will be resilient and yielding to some extent. Willow or sap gum wood has been found to be suitable for this purpose. Cleats or blocks of wood 3 are attached to the Specification of Letters Patent.
' Patented July 5, 1921.
1919. Serial No. 313,213.
in a plastic condition and, being spaced apart, water air, and surplus mortar will escape from the concrete and pass up between the cleats 3. The machine, shown in perspective, is a vibrating machine or machine for imparting vibrations which are to be extended throughout the mass of concrete, and this machine is shown only in conventional manner as it forms no part of the invention to be claimed herein. The vibrating machine imparts vibrations to the stringers 1 and 2 and to the cleats 3. The cleats transmit the vibrations from the vibrating machine to the mass of concrete. The vibrating machine moves from end to end on the stringers 1 and 2 and imparts the vibrations as it moves.
With such device as herein described, the operator will know how fast the vibrating machine must be moved by the amount of surplus mortar that is coming out of the concrete, and it can be seen that with the device set forth interposed between the pressure vibrating machine and the concrete slab in the road or street, momentarily information is available as to the state of the interior of the slab at all times while the slab is being compacted by the pressure vibrator. The operator will know practically the interior condition by the amount of surplus matter that is coming from the slab. With out such interposed device, the operator could only permit his machine to operate for an untimed period and then move on to adjoining area with the same uncertainty of results.
What I claim, is,-v
1. In an apparatus for imparting vibrations provided with a vibrating machine, means for transmitting the vibrations of the vibrating machine consisting of stringers and cross-bars spaced apart attached to said stringers, said stringers. forming tracks for the vibrating machine and said cross bars havin greater depth than width.
2. n a paving apparatus provided with a vibrating machine, means for transmitting the vibrations of said vibrating machine to the paving consisting of substantially flexible stringers forming tracks for and transmitting the vibrations of said machine and substantially rigid cleats spaced apart and greater depth than width and spaced apart attached to said stringers and in contact and yielding stringers attached to the upper with the paving. edges of said cleats and forming tracks for 10 3. In a paving apparatus provided with said vibrating machine. 5 a vibrating machine, means for transmitting In testimony whereof, I set my hand, this the vibrations of said vibrating machine to 29th day of April, A. D., 1919. the paving consisting of cleats having ROBERT C. STUBBS.
