1'0 (1. ill/HUM it III/Ivy concern;-

Be it known that I, WINFIELD S. LIVEN- GOOD, a citizen of the United States, resid ng at Kansas City, in the county of Jackson and- State of Missouri, have invented certain new and useful Improvements in Road-Graders,

after described, and shown in the accompanyingidrawings. n: the said drawings, Figure 1 is alrightside elevation .of a road scraper or grader constructed in accordance with my invention, a portion of the tongue, its spring, and oftlie hind wheels being broken away. Fig. 2 is a transverse sectional view taken on line II I] ofFig. 1, omitting the tool-box and seat, Fig. 3 is a central vertical-section of the front. ortion of the frame, including a portion the tongue or pole. l lig. 4 is a rear elevation of the machine, omitting the 311': which lie in front of line H Iron Fig- 1,. ig. 5 is a plan view of the hind axle and,the' platform, said axlebeing partly operators broken awe and 'partly'inhorizonta'l section and a. ifierent position of thepl'etform being shown in dotted lines. Fig. (i is a plan view of the rear portion of the machine,omitting the scraper-blade and the. connected parts. Fig.7 is a detached plan view of the parts'which are omitted in Fig. 6, the front porltion of the frame being indicated by dotted nice. for shifting. the scraper-blade transversely, parallel to its own length, the lower bearing of the vertical shaft being she in section.

, Referring 'to Figs. 1. and 4, the frame of the vehicle, supported by the-four-wheel runnmg-gear, consists of two longitudinal beanie 1 1, preferably of channel-section, as shown. Qrtcd by The rear ends of said beams are sup an arch 2, the ends of'which are cited to lugs 3 formed on the ends of a channel-bar 1, i I hereinafter termed the sliding bolster, as

it is mounted slidably upon the rear'axle- 5 for the purpose hereinafter stated.- Said" sliding bolster extends the full width of the frame to provide a Wide bearingsurface for,

axle 5, so the latter will not bend beneath the Weight of the machine when the bolster-is ends of beams 1 1 are supported as follows: An arched bolster 6, Fig. 12, is mounted ofi the front axle 7 by means of clips'8, and two. outwardly and upwardly inclined braces 9- 370 shifted longitudinally on the axle. The front are supported by said arch 6. As shown in FigsB and 12, these braces 9 sup ort a' transverse beam 10, on which rest t e forward ends of the side beams 1. A king-bolt 12 extends from cross-beam 10 down. throu h the arched bolster 6.

ing lug 13,, to which the bifurcated end of the tongue 14 is connected by a b0lt 15.. The

weight ofthe tongue is partially sftipported by 'a chain'16,} into which isconnected a heavy spring 17. The 'clevis 18011 the tongue is rovided for connection of a doubletree. (Npt'shownJ Two braces 19 extend from the lower ends of braces 9 to the inner sides of channel beams 1, to which they are connected at 20,,Fig. 1. A cross-bar 21, supporting seat-sprlii'g22, is bolted to the top beams l.' a

23 is a tool-box. Y

The scraper-plate 24 is supported as follows, reference being hadto large. 1 and 6':

Rigidly secured to t e 1 bottom of said bolster is aforwardly projectanges' of Two rock-shafts 25 and 2.6 are suipported by' 7 forward bearing-stands 27 an rearward bearing-stands 28, bolted to the channel- :jheamsfl. Crank- arms 29 and 30 are bent on the forward ends .OflSfl/id respective'shafts,

and pivotallyconnected to said crank-arms are tw'o'depending rods 31 and 32, the lower ends of which are pivotelly connected to e sway-bar 33, as most cleerly shown in Fig. 2.

. independent rotatable geared ring 43.

' The scraper-plate 1 whereby the y lt e ill thus be understood thatthe screperpie-Ce is supported through theintermediscy ,oi' the parts described, which parts include Said rods are connect-ed to the said cranks and to the bar 33 in such it manner thetthey re free to swing in any direction, forwardly end beckwerdly, es well es laterally. Bolted or riveted to the sway-her 33 by clamps 84 are the rearward ends of two forwardly-extendin beams 35, which converge and are secured to s shank 36. The end of the shank is provided with a. vertical opening of suffioient size to loosely receive the king-bolt 12, which extends therethrough, Fig. 3. Thus the shank 36 is free to be turned laterally for the purpose explained hereinafter.

As shown, the beams 35 are arched at 96 to permit the front wheels to pass thereun- (ler when the tongue is turned at one oblique angle.

Supported by 35 is e ring 37. Mend clamps 38. A cross-brace 40 may be employed, connecting the beams 35 and being secured to the ring 37 by means of a knee {i1 and bolts 42.

The ring flange 37,

the sway-bar 33 and beams (see Big. 10,) which supports on At the rear this ring is held see-ted by a plate 44;, bolted to the inner ring 37, bent upwardly and secured to the sweyber 33 at 45.

A heavy horseshoe-shnpedboi 46 (shown in Figs. 1, 2, and 7) is supported by the forward portion of the geared ring 43. As shown, this is efi'ected by means of bolts 47. The middle ortion oi the her 46 conforms to the curve 0 the ring, and from this middle portion it extends rearwardly, then downwardly, forming two shenks 48 48. V 49, secured to the rear face of the scraper plate 24, are pivotally connected to the ends of said shanks by means of bolts or pins 50. is further connected to the shanks 48 by means of arms 51, pivctally connected to the scraper st 52 and to the shanks by, bolts 53. Said arms are provided with a plurality of holes, as shown, in any one of which the bolts 53 may be placed,

pitch of the scraper-plate is adjusts'ble to difl'ere'ut angles when so desired.

This is effected by the clamps 37 is provided with a peripheral Hinges or knees 1 thereby the ends of the sorntpel plete 51 may l be separately raised or lowered by the opera.- l tor.

As shown in Figs. 2 end 6, the rocloshntn; 25 and 26- ej'ie provided with tensimi-sprinos 62 62, the purpose of which is to exert :i litting efiect upon the arms 29 30 and rods 3]. 32, thus relieving the worm-gears of a. part of theiri ction caused by the weignt of the port s supported by the arms 29 iitl. The lower ends of the said springs are connect ed to eyz bolts 63, end the springs zir secured to coins or equivalent devices 64-, d upon the opposite respective shefts in such e. manner as to tend to lift the nuns 29 30 for the purpose named.

In Fig. 2 65 ere two braces which extend from the geeredring 43 to the scraper-plate, they being connected, preferably, to the i knees or hin es ;49, as shown, and may consist of a. sings bar of motel, as shown.

I provide rneensio reising or lowering the l shank 36 on the scraper-beams 35 for the purpose of altering the pitch of the i rpm:

without handling the adjusters 01. As shownin Fig. 3, e chein 66 is connected to the shank 36 adjacent to the icing-bolt, passes over two pulleys 57 68, Fig. .2, and connects to :1 rod 69, Fig. 6, to the opposite end of which swinding-chein 70 is connected. 'lhis'chein posses, onto a smell drum '71, which may be the elongated hub of e ratchetwheel 72. '73 is the pawl, having the usual function. On the shaft of thedruin 7L is 11 hand-wheel 74, b turning which in one direction the Shani; 36 may be raised, thus changing the angle of the bGfiJ'llS 35, end by throwing off the pawl 73 end peri'nitting the hand-wheel to turn the beams will drop of their own weight until the shnnlr rests upon l the bolster 6.

Returning to the geared wheel 45 the means forroteiing it will now be doserilwd. Engaginfi the said ring at one side, preferably the right, is s worin To, the shoft oil which is journsled in two bearings 76 and T7.

The reerbeering '76 is SGHULll to the swayber'YiI-E ay 11 bolt 78. The front bearing 1", is supported 2 the beams 35.

Said worm-shett 80, Fig. ll is (onnected by n. universal joint 81 to at shell 82 in surh a manner that the shelf (an slide longitudinally within the sleeve 88, but will rotate the some by means of a pin R4, tighlly lixod therein sud projefling through two slots 95, tutjn the said sleeve. tihult 8'. extends ln k and is connected by :1 second universal joint 86 to e shalt 87, which is sol at sw. h an angle that a hand-wheel RR, fixed thereon, is at (onvenivnt height for the operator. By turning this wheel R8 the geared by av lirntlret 79, bolted to one of.

15 so ured to the top of arch 2.

4.. This holster is shown in transverse sec tion in Fig. 13. A stationary rark-ltar 89, F 1g. 5, is held beneath the rear axle, preferal;ly with bolts 90, passing through lugs 91' and 92. The forwardly-direoted teeth of the rack are engaged by a pinion 03, tixed upon the lower end of a vertical shaft 94. The upper bearing of said shaft is provided by a l:ar 95. (Shown in Figs. 4 and ti.) This bar is partly supported hygshatt 60, and its rear. end The. lower hearing of shaft 04 is provided by a block 96, (shown in section in Fig. 8,) bolted to the front of the sliding lzolster 4. A hand-wheel 98 is fixed upon the upper end of shaft 94, and Ly turning the-same the sliding lolst er 4 and the arch 2 maybe moved bodily to the right or the left, iarrying with them the scraper-plate 24 and all its supporting parts, hereinheforcdescribed. T

The operatorsplatf'orm 99 is attached'to the sliding holster 4 with tars 100 and is provided with traces 101, which are hung from the art-h 2. The liars 100 extend forwardly and upwardly, forming lrac-es 102. These brat es are S('( ured to the lower flanges of the channel-beams 1 1.

As indicated in Fig. 5, the platform 99 moveslaterally with the pinion 93 and-the bolster 4'. By turning hand-wheel 98 the operator can shift the scra er-plate laterally a few feet either to rightor eft. The advantage of-this movement will 1:5 appreciated by any one who has 0'. asion to manufacture or use a grader of this type. The rack 89 may be made longer than indi aled in F ig. 5 and the sliding par: 4 shortened, if it lie desired to inrease the range of the scrapers transverse movement.

Figs. 8 and 9 illustrate in detail my device or holding or lo-' king the pinion 93 at any point in its travel for the purpose of preventing'unintentional side motion of the frame.

103 is a verti ally slidalle and rotatalle rod, the lower end of whi 11 forms a dog that may he let down letween any two teeth of t he pinion 93. This rod is pressed downwardly lzy an expansion-spring.10 1. The upper end of the rod is bent at sul stantiallye right angle, forming a handle 105, Will. h rests upon an arc-shaped and in-lined g am 106, rigidly secured to plate with a tlolt 107. The op eration is obvious and requires no description.

In addition to the various adjustments do Stl'llletl l. have provided means for enallingthe operator to shift the s raper-plate longitudinally of its length without moving the 5 scribed.

As"6 5 shown in Fig. 6, a shaft 109, having bearings and 111, has a hand-wheel 112 mounted omits rear end and a worm 113 on its forward end., -Wor1n 113 engages a gear-wheel 114 on avertical-sh'aft 115, on'which' is fixed'a 7o rearwardlydextendingcrank 116, to which is pivotally connected a'rod 117. This rod is broken away in Fig. 6; but in Figs. 2 and 7 it is shown onnected to the sway-bar 33 .by'

a hinge-joint 118. .It;'.is thus evident that the 7 5 sway-b :11 may be moved in the direction of its length suspended by rods 31 32by turning hand-wheel 112. Braces 119 extend -from' the inner sides of bearing-stands'27 back to the chanr iel-bearns cured- I,

The forwardbearings 27 of rock-shafts 25 and 26' maybe constructed .integral with a 1, to which they arefse- 8o cross-bar 27, (shown in Fig.2,).the same'bcing bolted against the innersides of. beam 1. 8 5 with bolts 120. The upperendsof the bear- 'ings 27 may be: connected by .a brace 12- 1.
