- Application filed December 28, 1925. Se1'ia1 No. 78,021..

This invention relates tonew. and useful improvements in surfac ng or planing machines and has particular reference to such machines adapted primarily for use in the,

' inner face of each of-the ends 11 a'bearing planing'or surfacing of roads. e p An important object of thepresent lnvention is the provision of'such a machinefor use infremoving thebumps or irregularities on the surfaceof the road. -Another object of the invention is to provide such a machine 'havingarotrry cutting elementwhereby the bumps or irregularities V in the road will be cut away as themachine is propelled or drawn "thereover;

Another object of the invention 15 toyprovide such a machine which while simple in i construction, will nevertheless be strong,

sturdy and durable and eflicient in operation.

' p In the, drawings forming a part of this applicationand wherein li -ke'characters of j reference have been employed to designate 3 corresponding parts throughout the several Figure '1 is a side elevation ofa road I planing machine constructed in accordance with the present invention.

Figure 2 is a top plan view thereof with the engine platform and engin'e removed.

, shown one embodiment of the present invention, it will be seen that there is provided a. substantially rectangular frame A, compris Figure 3 is'a perspectiveview of one'of the guiding elements.

Reference now being had more particularly tothe accompanying drawings wherein for! the purpose of illustration has been ing the side members and the ends 11, said side members being provided adjacent each end thereof with the oppositely disposed longitudinal slots 13. The frame A is supported by the four'guide members 513, each raving therear vertical arm..14 and. the

' curved front arm connected at its lower end'with the lower end of the vertical arm 14., This arm is curved in the mannersho'wn inorder to facilitate themovements of the guide members over theirregularities in the road; Two of these guide members B are positioned within the frame A at each end thereof, one adjacent each of the sides 10.

' The rear vertical arms'ltof said members are secured within the smallsupporting bars 16'slidab1y mounted int-hefslots 13., while the arms 15 pass through; and are secured] i J 1.63 i 1,
