INVENTOR ATTOR NEY Patented June 10, 1930 UNITED STATES ANDREW J'. MONROE AND GEORGE w. MONROE, or ARTHUR, ILLINOIS ROAD PLANER Application filed September The object of this invention is to provide, in a road planer having a plurality of longitudinally extending diverging elements or scraping blades, a rear blade, or slicer, adapted to extend transversely at a suitable angle and spread the material moving rearwardly between the diverging elements.

A further object is to provide special means for mounting and controlling the rear blade, so that its position may be changed with reference to the diverging elements, and said third blade, or rear transverse blade may be caused to extend laterally to a greater distance on one side than on the other side.

A further object is to provide for changing the angular position of the slicer, or third blade, with reference to the path of travel of the machine.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements disclosed, it being understood that modifications may be made within the scope of the claims without departing from the spirit of the in- 2 vention.

In the drawings forming part of this application Figure l is a perspective view of the machine.

Figure 2 is a view in top plan.

Figure 3 is a view in side elevation, showing the rear portion of the machine, slightly modified.

Figure 4: is a plan view of the form of the device shown in Figure 3 including means for changing the angular position of the rear element termed a slicer.

Figure 5 is a detail view, in perspective, showing a latch for retaining an adjusted position of the frame for the third blade or slicer.

The frame of the machine includes the side bars or channels 10 and 11, and a rear transverse bar 12, and this frame is to be mounted on an axle 13 carrying wheels 14.

A bail-shaped frame 15 extends rearwardly from the main portion of the machine and is mounted for swinging movement as shown at 16. This frame may be raised or lowered by means of the mechanismillustrated, and

including a chain or flexible device 17 connected with the forked member 18, the latter mounting, if desired, a pulley wheel 19 for chain 20, the latter passing around an upper pulley 21, and passing thence downwardly to a winding drum or roller controlled by a hand wheel such as wheel 22.

The diverging blades or scraping blades are designated 24 and 25 and are tobe mounted in any suitable manner. The rear blade or slicer is designated 27, and is mounted by means of the frame of U-form, and including the downwardly extending portions 28, the side portions 29 and the forward curved portion 80. This frame just referred to is mounted for pivotal movement about the central vertical pin 83, and a latch including the retaining and releasing element 34'retains the frame for the rear blade, and said blade, in the position desired with reference to a plane extending transversely of the machine and perpendicularly of the path of travel.

-The latch 84 engages any of the apertures 30 of element 30. The frame 15 adapted to swing about a horizontal axis defined by transverse bar 16, is also adjustable laterally on said element 16, and an adjusted po- .sitionis retained by means of a pin 16 adapted to pass thru an aperture in a laterally extending portion 15 and thru any of the apertures 16 of bar 16.

In the modification shown in Figure 4, the lateral adjustment last indicated is effected by means of the particular construction now to be described.

The third blade 27 carried by frame 40 u is movable about a vertical axis defined by pin or the like 33 and rigid with the latter is a worm wheel 41 controlled by worm 42 and worm shaft 43 having universal connection with bar 44 similarly connected with shaft 15 controlled by handwheel 16. In this form of the construction, transverse bar 48 has a portion 19 thereof threaded and internally threaded element 49 receives said bar, the latter being rotated as by means of gear wheels 50 and 51, shaft 52 and hand wheel 53.

A plurality of adjustments are therefore blade-holding frame is connected in the manner described. As previously stated, the

' swinging frame is adjustable by hand or adjustable mechanically,falong bar 16, or the corresponding bar of Figures 3 and 4, and, the slicer blade or rear' bl'ade 27 may therefore be placed in all of the positions required for effective work, as'compared with the position of the bars-24 and 2 5.

Whatis claimed is:

1] In *amac-hme of the class described, a main frame, 'a-plurality 0f diverging blades, a rear 7 transversely extending blade constituting asli'cer, a second frame mounting the rear blade, a bar' for mounting the second frame for swinging movement at the rear of the frame first named, the swinging frame being slidabl'e alongthe bar and transversely :ofjthei'macliinefiiieans determining the ele- 'vation of theswingin'g, frame, and means for r'etaini'ngan adjusted position ofthe swinging frame on saidbar. i 1
