. lle it known' that l, A'Nv H. MILLER, a

citizen of the Unit-ed States, residing at Minburn, in the county of Dallas and State of 1o ."a, have invented certain new and useful Improvements in Grading and Leveling Machines, ofwhich the following is a specificati on.

This invention relates to improvements in grading' and leveling machines and one of the objects of the same to provide an improved machine of this character, which may he readily converted from one form or shape into another according to the work to bc performed.

further object is to provide an iniproi'cd machine of this character which will bc simple. durable and cheap in construction, and effective and eiicient in operation, and one which may be readily converted when desired.

Other and further objects will appear from the following specification and claims taken in connection with the accompanying drawings in which-,-

Figure 1 is a top plan view of an improved machine of this character.l constructed in accordance with the principles of this invention. Fig. 2 is'a top plan view of the machine showing the same `Lcd into another form. Figs. 3 and 4 are de il views partly inelevation and partly in section of one of the scraper supports and shaiwing the. scraper in different positions. Fig. is' atop planV view of the machine showingthe same converted into still another form. Fig. G is a detail sectional view taken on line GMG, Fig. 5. Fig. 7 is a side elevation of Fig. tion of the Scrapers and the intermediate holding' means for the Scrapers.

Referring more particulailyto the drawings and in the present form of the invenjtion, the numeral 10 designates generally a supporting truck arranged at the front end -of the machine and to which truck sectional -beams are pivotally connectedby means of the king pin 11 and these .beams are of sectional construct-ion, and 'respectively comf prise the sections 12-13,j14-15, 1(` -17,

.1S-19, 9.0-2.1, connected to the king pin 11,

so asto be laterally adjusted.

E ah Q, theheam '1S here Shown as com- Fig. S is a rear elevaprising .two sections, one of the sect-ions being provided with a tongue 22 and the other with a groove 23 intorwhich the tongue projects and the beams are provided with a series of apertures or openings 24, 25, (see.

Figs. 7, 3 and 4), for the reception of the fastening devices 26 by means of which the respective'sections of the beams are held to- Patented J une'8i,'1915. i

gether so'as to be adjustable with relation to each other, thereby rendering it possible to lengthen or shorten the beams as desired.

Pivotally connect-ed at the rear extremity of cach of the sections, 13, 15, 19 and 2 1, is an npriglit 2U, which may be of any desired height, and a brace 27 preferably in the forni of a bifurcated member is provided and stands astride of each of the respective sect1-:nis of cach of the beams, and this brace Q7v is connected by means of a fastening de vice Q8 and a series of apertures 29 in the beainsections to the respective beams at one end and is connected by means of a fasten ing device 30 to the respective uprights 2G, so that the. angle of the uprights with re spec-t to the vertical may be varied by removing the fastening device 23 and adjust ingl that end of the brace longitudinally of the beam and then reinserting the fastening device QS into the respective apertures 29. i

Connected with the section 17 of the intermediate beam is an arched shaped memiber preferably comprising the sections 31, 32 pivotallysecured to the beam section by means of connecting members 33, 34, and 35, although thisarched shaped member may if desired bev constructed of a singlev piece. -Braces 36 are connected with the beam section 17 and also with the sides of the arched 38 'are provided and the

beam sections

19, 21 are adapted to enter the sockets 41, 40 of the scraper 37 while the upright constituted by the side or roem:

ber 32 ofthe arched shaped member is adapted to enterl 'the socket 42, (as shown ,iri Fig. 1). The otherside 31 of the arched Vshaped member is adapted to enter the socket `.iig-45 of the scraperv 38 while the uprights of the beam section 15, 13 are adapted t0 respectively enter the sockets 44, 43 .on the,

scrapei' 38, and thereby hold the ends of the Scrapers 37, 38 in close proximity to each io other as shown in Fig.v 1 to adapt the ma-i chine to one form 'of grading. 'The vuprights and the s'crapers are held in this -p0` -sition in anyA desired or suitable -manner, such as by means of fastening'devices 46, 15 entering the sockets and engaging the respective uprights. -A seat 47 supported by f 'in a manner to be hereinafter described, and, theelement 48 of the'lseat support. is of .a

len h greater than the element 48 vin order l to co vpensate for this difference of the ele- -vation of the two sides of the machine.l

The Scrapers 38 may be attached to the 3,0 respective uprights in any manner, that. is

tosay, with the curved .portion of the blade low'ermostlas shown inFig. 3, or the blades.v

may be removed from the respective uprights and reversed, so that the curved edge will. be uppermost and the straight edge lowermost as shown .in Fig. 4, the sockets on the blades. having the'openings extending through' the opposite ends of the' sockets,

- being provided for this purpose.

40 If desired, a roller 52 maybe provided and attached, to the machine by means of a tongue 53, which engages a pin or projection 54 connected with a clip 55 and which. clip is secured to thev section 17 of the inten mediate beam, so that the roller will be vpreferably arranged in the rear 'of the intermediate edges of the scraper. A foot rest i 56 may lalso be provided for the operator, if desired. The scraper bladeI 37 is also pro-- 0 vided with a socket 57 while'the scraper blade 38vis also provided with a'socket 58,

.and these sockets are arranged adjacent the inner edges of the respective VScrapers and are adapted to receive the respective upj 55 rights of the arched shaped. members 32, 31

when they are removed from the sockets 42, 45 so that the blades may be shifted with respect to each other from the position shown v in Fig. 1 tothe positions shown 1n Fig. 2, thereby forming an opening betweenv the inner edges of the blades, and the beams connected with the outer edges of the respective blades may be adjusted to vary the angle of inclination of the blades longitudinally ,e135 the machinerie they maybe a* much-as the vlatter beams are of a lower elel' 4in any position with respect to each other,

asshown in Fig.'2. vIn this form of the inventionfthe roller/52 will follow theI opening between the inner edges of the blade.

Then it is desiredto convert the machine into the form shown. in Figs. 5 and'7, the 7 0 inner edge of the blade 38 fi's'detachedfrom the arch shaped member, and the lengths of the beams [comprising the' sections l2-l3- ,and 14-15 are varied or shortened. vInasration than the remaining beams', the scraper 75 blade 38F and the' connected beams, may be then swung under the remaining beams into the positions 'shown iii/Figs. 5 and 7. In this position and in order to support the end of the blade 38 which formerly constituted the innermost end thereof is provided another beam, arranged adjacent `the beam comprising the sections 20.-21fand this ad ditional beam isV also pivotally connected to the king lpin 11 .and comprises the sections`59, 60,'constructed in a manner similar to the remaining beams. An upright 61 is ,conf

nected with the beam section 60 and is adjustably held in position by means of a brace .62, and this upright 61 is adapted to enter ,A the socket 45, to hold the blade in its adf.

' just-ed position. 'When the machine, is 1n f .this forni, the

blades

37, 38 may be arranged Y p Y v 95.. that is the curved edges lmay be arranged f uppermost :if desired, .or' adjacent the ground, the blades may also be arranged to have the 'curved edges extending forwardly or rearwardly, or one forwardly or rear- '100 wardly `according to the work to be perl formed. rlhe .blade 38 is also adapted to be raised and lowered with respect tov the blade 37 so as'to dump the dirt when desired. In

order to 'accomplish this there is provided an actuating lever, 63, which `is pivotally supported preferably by the beam comprising the sections 20-21, anda segment 64 with which this leverv 63 coperates is also. provided. This lever 63 is vconnected asat end -of the beam 38, there'is provided another lever 66, similar to the lever63 Vand a? segment 67 is provided for the lever 66.

When the machine is vin the f orin S11-OWP ingu-'Ogg Fig. 5, the segment 67 and the lever 66ers connected with the'intermediate beam comprising the sections 16-,17 and the other end of 'the lever isconnected as 'at `68 with-the beam'comprisingv the sections 12v-13,v so'that '125 bothvof the levers 63, 66 vwill be conveniently l sitioned for the 4operator topermit the blade 38 to vbe raised or, lowered at will. v. When the-machine is not used inthe form aamainarigsirtwis .the 'form 1135- iot 65 with the beaml comprising the sections '5S- 60, so that when the. lever is actuated,
