DOUBLE CONTROL FOR ROAD-ROLLER SCRAPER. ATTACHMENTS.

Application filed October 24, 1923. Serial No. 670,494.

To all whom t may concern:

Beit known that we, WILLIAM T. BEATTY, FRANK S. DAVIS, and FRED D. WILSON, citizens of the United States, residing, re-

spectively, at Flossmoor, Homewood, and

Harvey, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Double Controls for Road-Roller Scraper Attachments, of which the following is a specification.

This invention relates to road roller maintainers of the general type shown in our earlier application, 'Serial Number 610,345, filed January 2, 1923, in which a road rolling machine is equipped with a transverse maintainer or 'scraper capable of working upon the surface of the road simultaneously with the rolling thereof.

The principal object of this invention is 'to provide a single mechanism under the control of an operator riding upon the roller which is not only capable as iln said prior application of raising and lowering the entire maintainer as a unit with reference to the roller and the road over which the inachine travels; but which is capable of selective manipulation to independently control the height of at least one end and preferably botli ends of the maintainer blade.

The\invention `consists in mechanism capable oil` attaining the foregoing /and other objects; which can be easily and cheaply made ;y whichl is satisfactory in use and is not readily liable to get out of order. More particularly, the invention consists in various features and details of construction which will be hereinafter more fully set forth in the specification and claims.

Referring to the drawings in which like numerals desi ate the same parts throughout the severa views:

Figure l is a side elevation of a road roller maintainer machine equipped with the mechanism of this invention in its preferred form.

Fivure 2 is a view of the opposite side of Figure 1, showing the extended side of` the blade. (See arrow 2, Fi 3.)

Figure 3 is a plan view o the mechanism of Figure 1.

Figure 4 is a front viewof the machine taken on the irregular line 4 4 of Figure 3.

Figure 5 is a sectional, detail view on the Iline 5-5 of Figure 1.

Figure 6 is a detail of the gearing used in the maintainer elevator mechanism, appearing in the upper lef-t hand portion of Figure 1.

Figure 7 is a detail plan Vvie-W on the line 7 7 of Figure l of a form of mechanism by which the operator may selectively elevate either the ent-ire maintainer blade or one end thereof.

Figure 8 is a corresponding plan view of an alternative construction b which the operator may selectively manipulate one mechanism to elevate or depress the entire maintainer mechanism or either selected end thereof.

The drawings show a road roller engine frame 10, carried onrear rollers 12 and a front roller mechanism 14, in the particular case here illustrated, two aligned rollers mounted on the same axle 16 inside a yoke 18 journalled on a vertical shaft 20 entering the arched member 22 on the frame 10. A11 operator occupying a vseat 24 at the rear ofthe machine can turn the vertical shaft 20 and consequently the roller 14 by properly manipulating an adjacent hand Wheel 26 on a shaft 28 operatively connected through gearing 30-32 to a segmental gear 34 secured to shaft 20 by any suitable means as key 36.

The conventional roller mechanism just described is equipped Wit-h a .U-shaped maintainer frame more fully described and claimed in said prior application comprising parallel side members 38 and 40 lying on opposite sides of roller 14 and a transverse cutting or maintainer blade 42 ca.- pable of angular adjustment between the full line and dotted line positions of Figure 3 through the agency of adjusting bolts 44 cooperating holes 46 therefor and removable braces 48'. This frame is, as in said prior application, secured about. the roller 14 and on movement yof the roller pushed or pulled along the road through the agency of diagonal brace members 50 and 52 adjustably attached to the body 10- of the roller through any suitable means as, for instance, set screws or bolts 56 selectively insertable in holes 58 or 60, as thev case may be, provided for them in the regg apeoaeee spective members 52 and 50. As fully set forth in said rior application, the further end of each iagonal brace rod and 52 is engaged by a downwardly movable rod 62 provided with a cushion spring mechanism 6a with the result that each adjacent side member of the lll-shaped maintainer frame and consequently the blade 4:2 is pressed rmly upon the ground. rlhe mechanism for exerting this pressing action on these rods 62 and conversely for elevating them constitutin a principal feature ot this invention wil now be described. l

'lhe upper end of the rod 62 on the lett hand side of the machine as viewed in Figure 4 is pivotally attached at 66 to a lever arm 68 carried by a shaft 70, journalled in a bracket 71 provided for it, extending across the machine.

rl`he right hand end ot the bracket 71 as viewed in Figure 4 has rigidly secured to it by any suitable means. as, for instance. bolts 72, a gear housing 74 carrying two parallel segmental gears 76 and 78, the former rigidly secured to shaft by any suitable means as, for instance. a key 80, the latter freely rotatable on said shalt 70. lournalled on the right handend of shaft 70, as viewed in Figure Il, is a Vlever arm 82, resembling in outward appearance lever 68. heretofore referred to, and detachably pivotally connected to the right hand rod 62 by any Suitable means as a pin 84C. The hub 86 of lever 82 and the hub 88 ot' segmental gear 78 are detachably connected together around an intervening portion 90 of the gear housing wall by means of suitably disposed lugs 92 and 94 and interconnectin bolt 96 (see Figure 5).

Extending through the gear housing 7-1 and suitably journaled in its opposite walls are parallel shafts 98 and 100 carrying, respectively, worms 102 and 101i meshing. respectively, with segmental gears 76 and 78. ln the specific form of the invention shown in Figure 7, in which-the operator can selectively elevate or depress the entire main-` tainer or elevate or depress one end of the blade 4:2, in the particular case `v`here illustrated, the right hand end as viewed in Figure 4, shait extends back to a point iii proximity to the drivers seat 24 and there carries a single wheel 106. Slidably mounted. upon this shaft 100 and readily manipultab e by hand lever 108 adjacent to the drivers seat is a connecting sleeve 110 attached to a gear 112 mounted for limited reciprocation along shaft 100 but prevented from rotation thereon by any suitable means, as for instance, a spline connection 114. rll`his gear 112 meshes with corresponding gear 116 rigid on shaft 98 and the limits ot movement along the spline connection 114 are such that the operator can by properly manipulating handle 108 cause the gears 112 and 116 to mesh as shown in Figure 7, or can move gear 112 along shaft 100 until it is entirely out of mesh with gear 116. l/Vhen the gears are in mesh asshown in Figure 7, rotation of hand wheel 106 will cause both segmental gears 76 and 78 to move in unison and will consequently simultaneously elevate or depress rods 62 and consequently the entire maintainer mechanism. When gear 112 is out ot' mesh with gear 116, the friction in worm 102 locks shaft 98 and consequently that part of the maintainer mechanism attached thereto; while rotation of shaft 100 manipulates segmental gear 78 to, at `the will of the operator, raise or lower the right hand end ot the maintainer blade 42 as viewed in Figure 4l.

ln the alternative construction, shown in Figure 8, shaft 98 is according to the drawings equipped with a slightly wider gear 120, replacing gear 116. Shaft 100 as before extends to the drivers seat 24 and is there equipped with a hand wheel 106. 'l` he mechanism 110*112. of Figure 7 is removed and in this construction replaced by a longitudinally reciprocable sleeve 124 carrying rigid thereon near hand wheel 106 another hand wheel 126. Rigidly secured to the opposite end of this member 124 by any suitable means as bolt or screw 128 is a clutch member 130 provided with clutch teeth 132 inter-fitting with other clutch teeth 134 on another clutch member 136 rigidlyl secured to shaft 100 by an)T suitable means as, for instance, a pin 138. Rigid on clutch member 130 is a gear 140 meshing with gear 120. Wheel 128 and parts 1244-130 and gear are sldable lengthwise of shaft 100 between the position shown in Figure 8 and a position to the leftthereof in which clutch teeth 132 intertit with clutch teeth 13-1` Aand thus lock these parts on shaft 100.

When the parts are in the position shown in Figure 8 and the operator?manipulates hand wheel 106. he causes shaft 100 torock segmental gear 78 to thus manipulate up or down as the case may be the right hand end of the maintainer as viewed in Figure 4. `When, under the same conditions. the operator rotates wheel 126, `he causes gear 140 to rotate gear 120 and consequently through the parts attached thereto rock segmental gear 76 to raise or lower. as the case may be, the lett hand end of the maintainer as viewed in Figure 4. When the operator takes hold of the handle 126 and shoves the gear 140 to the lett, as viewed in Figure 8.

until clutch teeth 132 and 13d intermesh.l

then manipulation of either hand wheel 106 or 126 will cause gears 140 and120 to rotate in unison thus moving Asegmental gears 76 and 78 in unison thus raising or lowering as the case may be the entire maintainer.

From the foregoing, it will be seen that IIL'.

by installing the mechanism of Figure 7 the operator on (seat 24 can by the Imanipulation of a. single hand wheel and shaft selectively raise or lower the entire maintainer or raise or lower a given predetermined end thereof; and that, by the use of the mechanism of Figure 8 still carried by a single shaft extending forward from the operators position, the operator can at will by rotating that one shaft or mechanism journaled thereon raise or lower the entire maintainer or raise or lower either end thereof. By the use of these simple, readily v installed mechanisms, the operator on seat 24 has absolute control of the maintainer blade 42 at the front of the machine to make the road or other surface worked upon as desired.

The maintainer mechanism described is held against lateral movement with reference to the roller frame by a transverse rod 140 and' rattling of the parts is prevented by a cushion spring 142 adjustably held in place by any suitable means as, for instance, lock nut mechanism 144.

Manipulation of the maintainer frame as described is materially facilitated by the use of oppositely disposed cushion springs 15()- and 152 attached at their lower ends to suitable points on the maintainer frames and at their upper ends to. short lever arms 154 or 156, as the case may be, extending on the opposite side of-shaft 70 from the respective lever arms 68 and 82.
