COMBINATION BLADE EXTENSION AND WING Fon Roan MACHINES.

Application led July 28, 1922. SerialN'o. 578,086.

To all whom t may concern.'

Be it known that I, WILLIAM Flossmoor, in the county of Cook .and State of Illinois, have invented a certain new and useful Improvement in Combination Blade Extensions and Wings for Road Machines,-

of which the following is a specification.

This invention relates to road Working c machines employing a transverse blade of substantial length, sharpened not only at its bottom for scraping the road surface but at itsends for cuttin banks (or piles of material at-the side o the road.

The main object of the invention is to provide a supplementalV upright board or plate which, while suiciently permanently attached to the blade so that 1t cannot be left at the home of the machine or by the roadside, is adjustable to three different positions: (a) that in which it is a forwardly extending wing rendering the blade a conventional form of scraper; (b) that in which it is an extension in substantial alignment with the blade, thereby len thening it for any suit-able purpose; and (c that in which it is supported above and behind the blade toutof the way of the blade in all of its working movements.

The invention consists in mechanism capable-of attaining the foregoing and other ob-` features and details of construction whichA -will beli'ereafter morev fully set forth in the specification'and claims.

Referring to the drawings in which like numerals designate the same parts throughout the several views:

Figure 5 is a changed position view of l the hinge mechanism of Figure 4.

Figure 6 is a rear view of the blade with the parts positioned as shown in Figure 3. Figure 7. is an enlarged plan view o'f the plate carrying hinge mech'anismwhen the parts are in the position of Figures 1 and 2.

Figure 8 is a side view of the hinge mechanism when in the position of Figure 7.

Figure 9 is a perspective View taken from the side and rear of the blade when the plate is in forwardly extending wing position.

Figure 10 is a disassembled view ofthe plate and hinge suppoting parts separated `one from the other.

The mechanism of this' invention is applicable to the end of any conventional form' of` road machine blade. For the purposes of illustration, the device is shown applied to opposite ends of the blade 10, extending transversely vof the main frame of. a conventional form of road machine 12 sustained by Wheels 14 and v16. The blade is shown conventionally mounted on blade carrying frame 18,^pivoted to the front axle at 20 so as to be controllable in conventional manner by -man-ipulating the Lhandwheels 22. The blade is directly supported from the, fram@I 24 which is conventionally rotatable under the control olf-'operating wheel 26 and gear mechanism 27 between the .angular positions of Figures 2 and 3.

The blade 10 may be of any suitable cross section. In the particularcase here illustrated, it iscurved as shown, for instance, in clot-ted lines Figure 8, and is provided at its bottom with a'v cutting edge 28 engageable with theroad surface and with sharpened vertical end edges 30 adapted for severing earth material from banks or piles lat the side of the road adjacent to the path of travel of the road machine. The problem solved bythis invention is to apply,in proximity to these vertical cutting edges 30, plate or board-members 32 adapted to be selectively moved to the position of Figure 2 in which they, acting asl conventional Wings convertl the blade into a scraper; to

the position of Figure 2a in which they act as conventional extensions of the blade and therefore enable the user to tilt the blade to the angular position of Figure 3 with reference to the main frame 12'of the machine and still scrape full roadwidlih; and, finally, to the position as shown at theirl ft hand portions of Figures 3 and G in which they are simply carried by the macl1ine,'spe cifically by the blade, 'o ut of its way.-

In order to secure .thisdesired result, these plates are carried on supporting hinge mechanisms secured to opposite ends of the blade, the hinge mechanisms being identical except that one is a right hand and the other is a left. These hinge mechanisms or pivotal mounting devices for the plates each include two parallel hinge pivotf shafts or bolts 34 and 3G spaced apart a substantial distance by a compound leaf or lever 40-42, adjustable vertically withreference to cach other i by pinL 44 and slot 46 connections, clearly appearing in Figures 9 and 10. As one plate 40 of this leaf includes one hinge pivot 34 and the other leaf member 42h1- cludes the other hinge pivot 36, it is obvious that when pivot member 36 is rigidly positioned on the blade, as it isby means of the stationary hinge leaf 48 secured in place by bolts or screws 50, the hinge pivot 34 can be adjusted vertically with reference to the blade through the conventional operation of the pin and slot connecting device 44-46. The length of the common leaf 40--42between hinge pivots is such that when theparts arein the position ofFigure 9, the plate 32 attached to hinge :pivot 34 by means of its independent( hinge leaf 52 will .just lit around the end of the blade and act as a wing in conventional manner, and that when the parts are swung into the position show in the left hand half of Figure 6, the plate 32 is carried toward the center of the piachine a very substantial distance awayl rom the. end. cutting edge 30 of 'the blade, thereby leaving that4 end cutting "edge free to act 1n bank cut-ting or the like as may be required of the general machine.

'lightening theworking load upon the ex-x p `Plate 32 is vertically adjustable angularly wlth reference to the hinge l'wing 52 throughvthe agency of circular slots 54 and pin Aor bolt connections 56 through thein to enable the operator to' selectively position the adjacent pla-te 32 in the full-line position at, the r1ght hand half of Figure 6 in which the outer end of vthe pla-te extension is sllghtly olf from the groundr 58, thereby tension or inthe dotted line' position in Leccese lwhich the lower edge of the'plate contacts' the ground.

As the plate when operating either as a wing or an extension of blade l0 has to carry' considerably Working strain, it is,

necessary that it be stronglyJ supported in either position.

ln the preferred form of construction nowl under discussion, this vis accomplished by providing the hinge leaves'` 40 and 52 with horizontally disposed roverlapping quadrant fianges 60 and (32, suitably perforated with selectively interfitting holes 64 and 66 so that when the parts are prop-I erly assembled, the locking bolts 68 can be tion.

In order ltodetachably secure the hinge .mechanism or pivotal mounting device for, the plate to the end of the blade 10, lwhen the plate isin wing or extension positions,a pi-voted Alocking dog 72 is journalled on the hinge bolt 34 to'v rock through a suitable notch 74 in hingeleaf 52 and catch over the end cutting edge 30 of the blade 10. This dog 7 2 is detachably secured in locked position by means ofy a. removable pin 76 inserted through a perforation 78, provided for it in the' dog. The end of th-e dog 72 which carries this perforation 78 is, vafter removal of the `pin 76;' rockable through a notch 80 inthe hinge leaf .4Q/to release thev hookgliend 82 ofthe dog from the blade edge 30. By the construction just described, the intermediate or common leaf 40j42 may be rigidlylocked in the position of- Figure 9 to the back of the'blade 10 'and kept there While the plate 3 2 is swung .betwen wing" and extension position as desiredg 0n the other hand, when the pin 7 6 is removed and the latch dog 72 released the operator can freely move theV hinge parts from the position of Figure 9 Yto that of the left hand part of Figure 6 in which the plate is car-l ried back of the blade and clear of its incutting edge. When the parts are moved4 to this position, it is desirable to adjust the pin and slot connections 44-46, as shown in Figure 6, to elevate the plate entirely clear of the ground, readjustimgg'.these parts to vthe position' of Figure 9 when the plate is returned to either Wing or extension working position.

ln Figure 8, the hinge bolt34is shown in an exaggerated way at avery marked 'angle to thevertical axis of the blade 10 and the hinged end of plate 32. In practice, the hinge pivots are placed at an angle less than that shown so that the plate will, When swung from wing to extension working position, be normally in the full line position of the right hand end of Figure 6 with its outer endv slightly elevated from the ground 58.

In the general operation of the device, if, the road machine is to use its blade 10 'for normal road cutting operations, with the blade at right angles to the axis of the machine frame as shown in Figures l and 2, the plate 32 will be normally assembled out of use as shown in the left hand half-of Figure 6. If the operator desires' toV shift the blade to the angular position of Figure 3 and yet Wants to 'work full Width oaf road, he will adjust the bolts 114 and 68 and lthe latch 72 to assemble the parts as shown in the right hand half of Figure 6. If the operator desires to use the blade as a scraper for delivering loose dirt in holes along the surface of the r'oad, he will remove the bolts 68 and adjust the plates to the Lvving position of Figure 2 and then replace the bolt 68.

By the use of thedevice described, the road machine driver always has the Working plates 32 with `him when he Wants to use them and he can at will use them as Wings or extensions IVhat I! claim is:
