The-apparatusis To the lower ends of these han ers 10;, Lseespecially designed for thepracticingof-the-methcure guard Pl e l he nard plates bein .od ofplacing concreteof my Patent No. 787,449, clamped to the hangers-by means ofrthe clampdated January 6,1931. ki a l4 and suitable bo ts or rivets. The Ihave, in the accompanying drawings, illusguard platesdepend atthe innensideoflthe'form 50 trated only such portions of a paving :machine members 3 to travelalongthe same as the maor apparatus as seemsto me to be necessary or chine'isadvanced.

The hangers Ill also carry the longitudinally disposed auxiliary vibratory elements I 6 which have upwardly projecting brackets I I secured to the hangers I 0 intermediate the point of their attachment to the plates II and the attachment of the guard plates thereto by means of suitable clamping plates I8 and the bolts or rivets l9.
' This provides a support for the vibratory elements It which permits free vibratory movement thereof.
The vibratory elements I6 are preferably tubular and have tapered or conical ends 20. In the preferred embodiment, the vibratory elements constitute housings for electric motors conventionally shown at 2|, the rotors 22 of which are provided with unbalancing weights 23. Electrical connections for the motors are convention- 'ally indicated at 24.
By this means, the vibratory elements iii are vibrated at high frequency and in opposed relation to the guardplates but out of contact therewith. The mass of concrete is indicated at 25 and the vibrations set up therein by the vibratory elements is indicated at 26, see Fig. 2.
The guard plates are effective in preventing undesirable vibration of the forms. However, the concrete mass is vibrated along the forms .so that portions not directly subjected to the vibrations of the vibratory element 6 are effectively vibrated.
In the embodiment shown in Fig. 4, the vibratory element 21' is in the form of a plate having a vibratory motor 28 mounted on the top thereof. This plate 21 is suspended from the flexible hangers 29 from the support 3!] pivoted at 3! and raised and lowered by means of the cable 32 and the winch 33, being supported in its lowered position by means of the cable. In this illustration, the guard plate is omitted.
In the embodiment of .my invention illustrated in Fig. 5, the'plate 34 is mounted by means of the flexible hanger 35 from the pivoted support 36 which is adjusted by means of the cable -31. The main vibratory element 38 in this embodiment is provided with a transversely disposed shoe 39 at the end thereof acting in opposed relation to the guard plate 34. A similar arrangement is illustrated in my application for Letters Patent Serial No. 234,918, the flexible mounting of the guard plate, however, not being disclosed in that application.
I have illustrated and described my improvements in what I consider highly practical embodiments thereof. I have not attempted to illustrate or describe other modifications or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
