scan-near.

To all whom it may concern:

Be it known that I, FRANKLIN L. Games, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Im rovements in vRoad-Floats; and I do here y declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My inyention relates to improvements in road floats, and its object is to provide a simple effective device having various new and useful features hereinafter more fully described and particularly pointed out in the claims.

My device consists essentially of a series of beams horizontally disposed, arranged in parallel relation and spaced apart, cr nnc'ting bars pivotally attached thereto, whereby the beams are adjusted, and a braceadjustably connected thereto whereby the bars are held in adjustment at various distances from each other and overlapping each other more or less. a blade attached to the first beam of the series, the same being recessed at intervals at its lower edge and the metal between the recesses twisted to form diagonal cutting blades, and straight edged scraping'blades attached to the remaining beams, as will more fully appear by reference to the accompanying drawings in which:

Figure 1 is a perspective of a device embodying my invention and adjusted foruse; Fig. 2 a plan view of the same; Fig. 3 an enlar ed detail of a portion of the cutting blade an beam in elevation; Fig. 4 the same showing an inverted plan; and, Fig. 5, a transverse section of the same on the line 5-5 of Fig. 3.

Like numbers refer to like parts in all of the figures.

1, 2, and 3 represent a series of beams horizontally disposed and spaced apart in parallel relation, said beams being preferably angle iron bars each with its horizontal-memher above and a downwardl extended vertical member at the rear. hese beams are connected by channel bars pivotally attached thereto by bolts 11, whereby they are spaced apart at various distances as referred, and will overlap and extend partially beyond each other in series according to adjustment. To adjust and hold these beams and bars, a brace bar 5 preferably of angle Patented April 20, 1909.

1 iron is pivotally connected to the front beam 1 near one end thereof, and adjustably connected to the rear beam 3 near the other end by a bolt 6 adjustable in a series of openings 7, in the horizontal member ofthe beam 3.

To the vertical member of the forward beam 1 is bolted a 'strip of metal near its upper edge arranged substantially vertical an extending below the beam, that portion below the beam being recessed or slotted vertically at regular intervals and twisted to form diagonally disposed cutting blades which cut and turn the soil. To the vertical member of each remaining beam is attached a scraping blade 8 consisting of a rectangular strip of steel which smooths and levels the soil disintegrated by the cutting blades on the beam 1.

12 are shackles on the beam 1 by means of which any suitable means of moving the device forward may be attached. The tendency of the beams is to turn somewhatdiagonal to the direction of movement due to the laterally pro'ecting position of the successive beams whereby the tendency of the device is to move the material longitudinall of the cutters and scra ers and thus more effectually pulverize an move the same, the

degree of projection and distance apart of.

the beams being determinedsby the adjustment of the brace bar 5 relative to the openin 7;

' What I claim is:

1. A road float comprising a series of horizontally disposed beams spaced apart, bars connecting the beams and pivotally attached thereto, a brace bar adjustably connecting the beams, a disintegratin member attached to the forward beam, -an a straight edged scraper attached to each remaining beam.

2. A road float com rising, three angle iron beams, two channe bars pivotally connected thereto and adjustably spacin the same apart, a brace bar pivoted to one eam a plate attached to the forward beam and having its lower edge vertically recessedand twisted out of' alinement forming mchned attached to the remaining beams.

an -le iron beams spaced apart in parallel relation and each having a horizontally d sposed upper member and a vertically disposed rear member, two transverse channel cutters, and straight edged scraping blades- 3. In a road float, the combination of three and ad ustably connected to another beam,

bars pivotally attached to the beams, a brace 1 rectangular plate attached to the vertical 1?. bar plvoted to the forward beam and adjustmember-0f each of the other beams. ably attached to the rear beam, a disinte- In testimony whereof I affix my signature grating member attached to the forward. in'presence of two witnesses.

earn and consistin of a plate projecting below said beam and aving its lower part verl tically recessed at intervals and twisted to Witnesses: form diagonally disposed blades, and a PALMER A. Jones, scraper blade consisting of a straight edged 1 GEQRGIANA CHACE.
