ROAD-DRAG.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed April 24, 1914. Serial No. 834,246.

To all whom it may concern:

Be it known that we, HARRY G. MosorrnnnosoH and CHARLES F. BROCKER, citizens of the United States, residing at Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Road-Drags, of which the following is a specification.

Our invention relates to road making and repairing mechanisms, and particularly to road scrapers or drags.

The primary object of our invention is the provision of a very simple, easily operated and cheaply constructed road drag wherein one or more blades may be used and wherein the angle of the blades may be changed or adjusted to suit various exigencies of road making.

A further object of the invention is to provide a road drag in which the angle of the road scraping blade or blades, and the angle of the machine as a whole may be changed to suit various exigencies of road making.

A further object of the invention is to pro vide a road drag with a steering ground engaging member disposed behind the blade carrying portion of the drag, this ground engaging member being of such construction as to cause the machine to resist lateral movement due to the inclination of the blades.

A further object of the invention is to so construct the drag that the forward blade of the drag and the rear blade or roller, whichever is used, may be angular-1y adjusted relative to each other.

Still another object of the invention is to provide means whereby the operator on the machine may readily adjust the forward scraper blade without leaving his seat.

Other objects will appear in the course of the following description.

Our invention is illustrated in the accompanying drawings wherein:

Figure 1 is a plan View of a road drag constructed in accordance with our invention. Fig. 2 is a side elevation on an enlarged scale of a portion of the drag. Fig. 3 is a vertical sectional view on the line 3--3 of Fig. 2. Fig. 1 is a detail perspective view of the guiding or steering runner and the means for operatively connecting the beams. Fig. 5 is a perspective detail view of the means whereby the latching devices may be shifted or operated. Fig. 6 is a perspective view of the link connecting the bolt rods to the operating lever links. Fig. 7 is a fragmentary perspective view of the supplemental blade.

Corresponding and like parts are referred to in the following description and indicated n all the views of the accompanying drawings by the same reference characters.

Referring to these drawings, 2 designates a scraper beam which is relatively heavy, has a flat upper surface 3, a flat forward surface 1 and a rounded rear and under face 5.

Attached to the front face of the beam 2 is the scraper blade 6 which at its upper end is formed with the distributing hood 7 which extends in a curve forward and slightly downward. Rotatably mounted upon the ends of the beam 2 are the rearwardly projecting arms 8. The forward ends of these arms are formed with laterally projecting gudgeons 9 which enter bearing openings in the beam, these bearing openings being surrounded with a bushing 10 shown in dotted lines in Fig. 2. The arms 8 are semicylindrical in shape as shown in Fig. 3 and are twisted at their rear ends so as to provide at their forward ends a vertical, flat inner surface and at their rear ends a horizontal under surface. These arms 8 are pivotally connected to rearwardly extending frame beams 11 and 12. When the scraper is in use as shown in Fig. 1, the beam 11 extends parallel to the line of draft while the beam 12 extends at an acute angle to the beam 11.

The beams 11 and 12 are connected to the arms 8 by just the angle of the beams 11 and 12 with relation to these arms 8, each of the beams 11 and 12 at its forward end is provided with a plate 14 which is rigidly attached to the upper face of the beam, this plate being formed with a plurality of perforations 15 arranged in the are of a circle and over which the rearward extremity of the corresponding arm 8 operates. This free extremity of the corresponding arm 8 is held adjusted to any desired angle by inserting a pin 16 in the proper perforation 15.

The beam 12 at its rear end rests upon the beam 11 and is held thereto by a pin 17 passing through any one of a series of perforations 18 formed upon the beam 12 and any one of a series of perforations 19 formed upon the beam 11. This pin is held braced and the beam 12 supported in proper relation upon the beam 11 by means of a metalbolts or pins 13. In order to adlic strap 20 which as illustrated in Fig. i is attached at its ends to the beam 11 and arches over the beam 12, and is adjustable therealong.

Attached to the rear end of the beam 11 and therefore extending parallel to the line of draft, is a ground engaging member illustrated in full lines in Fig. 4 as a relatively sharp runner, this runner being designated 21. This runner cuts into the ground at the side of the road and resists any tendency of the machine to slue sidewise. The rear end of the beam 11 may also be supported by means of a roller 22 or caster wheel. lVe do not wish to be limited to the specific form of ground engaging device illustrated in Fig. 4 as a roller as other forms of ground engaging device might be used though not as effectively.

Extending parallel to the beam 2 is a supporting bar 23 shown most plainly in Fig. 1. This supporting bar extends nearly the entire length of the beam 2 and at its ends is inwardly and downwardly bent as at 24:. This bar is also semicylindrical in cross section and is twisted at its middle as shown clearly in Fig. l. The extremities of the inwardly bent ends 2% are downwardly bent to extend over the curved surface of the member 2 as at 25 and are attached to said member or beam in any suitable manner as by screws or bolts. Thus this bar 23 is rigidly connected to the beam 2 and any depression of the bar 23 acts to rotate the beam 2 with relation to the arms 8.

Mounted upon the bar 23 and preferably pivoted thereto is a lever 26. This lever is pivoted upon a bolt 27 to the bar 23 and extends toward and beneath the beam 2 and is attached to the curved under face 5 of the beam by means of screws or bolts as shown in dotted lines in Fig. 1. Thus this lever 26 is likewise rigid with the beam 2 and any movement of the lever will tend to rock the beam.

For the purpose of holding the lever 26, the bar 23 andthe beam 2 locked in any desired adjusted position, we provide a transversely extending bar 28 which at its ends is attached to the arms 8 as illustrated clearly in Fig. 3. Mounted upon this bar 28 at each end of the machine are the notched supports 29. These have the form of an inverted U and through the legs 30 of each support the rod 28 loosely. passes. The forward edges of each of the legs 30 is notched as at 31 and these legs may also be perforated as at 32 if desired.

Disposed inward of the angularly bent ends 24 of the bar 23 are the guiding brackets 33. Passing through these guiding brackets are the oppositely disposed looking rods or bolts 34, these bolts being also guided by guiding brackets '35 projecting rearward from the beam 2. The outer ends of these locking rods or bolts 34- are adapted to be projected into any one of the notches 31 or into any one of the perforations These locking rods are normally forced into projected position by the springs 36 each of which at one end bear against the corresponding guiding bracket 33, the other end of each spring bearing against a collar 37 formed upon the rod 34-. For the purpose of manually retracting these locking rods 3i in order to permit the adjustment of the beam 2, we mount upon the lever 26 the retatable lever 33, the extremity of which is formed with a handle 39. From this lever extends a pull rod 40.

Pivotally mounted upon the bar 23 at its junction with the lever 26 are the angular levers el-l mounted in diverging relation. Each of these levers has approximately the shape of a bell crank having an outward] 1 and forwardly directed arm and a laterally projecting arm 42. To these laterally projecting arms 1-2 are attached links 43 which connect these arms to an eye -l-l formed on the extremity of the rod 40. The

forward ends of the levers ll are connected by means of links 45 to the rods 31- as illustrated in Fig. 6. These links 45 preferably have the shape illustrated in Fig. (5. In other words, each link at its rear end is longitudinally slitted as at t? and one lateral portion of the bifurcated end so formed is bent downward as at 48 and then upward beneath the extremity of the lever 4-1. A pin 49 passes through the bifurcated clip so formed and through the extremity of the lever 41-1. This is a convenient way to form these links but we do not of course wish to be limited thereto.

It will be obvious now that when the lever 38 is pulled rearward, the locking rods 34 will be retracted against the force of the springs 36 and that when so retracted, the beam 2 may be rotated upon its longitudinal axis and thus the angle of inclination of the blade 6 changed to suit any desired circumstances of operation. Thus if the lever 26 is raised to its full height and the locking rods engage with the uppermost notch 31. or with the uppermost perforation 32, the blade 6 will be directed downward and rearward. If, on the contrary, the locking rods are enged with the lowermost notch 31, the blade 6 will be directed downward and forward and that any intermediate inclination of the blade may be secured by adjusting the locking rods in the proper notches in the supporting members 29. Of course, as soon as the handle 39 is released, the springs 36 will cause the locking bolts or rods to be projected and the beam locked.

Disposed behind the beam 2 is a roller 50 (for which a supplemental scraper may be substituted as will be later stated). This roller 50 is supported at its ends in vertically extending screw threaded standards 51 and each standard passes through a screw threaded sleeve 52, the standard being held in adjusted relation to said sleeve by a set screw 52 or by set nuts 53. It will thus be seen that the roller may be shifted downward or lifted to a predetermined distance with relation to the arms 8 and then held in its adjusted position by means of the set screw 58. Mounted upon each standard 51 is a U-shaped yoke or are 54. This yoke has the upper and lower arms 55 through which the corresponding standard 51 passes, and the arcuate body 56 of the yoke is provided with a plurality of perforations 57. A pin 58 passes through any desired one of the perforations and through a perforation formed in the arm 8 and in a strap 58*. The sleeve 52 is rotatably mounted upon the arm 8 and it will thus be seen that the angle of the standards 51 may be changed or adjusted and that inasmuch as the yoke 54 moves with the standards, the standards may be held adjusted at any angular position by means of the pins 58. Thus we can secure either a vertical adjustment of the roller 50 or an angular adjustment of the standards supporting the roller with relation to the arms 8.

Under some circumstances it is desirable to use an auxiliary supplemental scraper operating behind the scraper 6, and such a scraper is illustratedin Fig. 7 and is designated 59. This scraper may be of any suitable construction but has a length equal to the scraper 6 and is preferably reinforced along its length by means of a backing 60 which may be attached to the scraper or formed integral therewith. The extremities of the scraper are provided with the upwardly extending screw threaded standards 61 which are equivalent to the standards 51 and may be inserted through the sleeves 52. The angle of this scraper and its depth of cut may be adjusted in exactly the same manner as the height of the roller 50 may be adjusted and the angle of its standards 51. For the purpose of additionally supporting the scraper blade 59, we provide upon the scraper blade near the opposite ends thereof, the eyes 62 having downwardly extending shanks 63 which are attached by bolts or rivets to the blade 59. These eyes 62 are intended to loosely embrace the rod 28 so as to support the intermediate portions of the scraper blade.

.Vhile any desired draft attachment may be used for the drag, we preferably attach to the forward face of the beam 2, the rings 64 to which the draft chains 65 are adapted to be connected. These chains are adapted to be connected to any suitable whiflietrees or other draft eveners. Mounted upon the beam 12 and extending up therefrom is the drivers seat 66, this seat being disposed at a convenient position with relation to the lever 26 so that the lever may be readily operated.

The operation of our invention will be obvious from what has gone before. The drag is drawn along the road or other surface to be operated upon and as circumstances require, the inclination of the scraper blade will be changed. If the lever 26 be fully depressed and held downward, the drag will be supported entirely by the roller 50, the blade 6 being held entirely free from the ground. If, however, the lever is released, then the scraper will contact with the ground, the amount of cut, however, being determined by the inclination of the scraper 6 and the adjustment of the roller 50. The hood 7 prevents the dirt from passing over the top of the beam and returns the dirt to the surface, the scraper thus acting to take the dirt which has been scraped from the road and distributed over the surface of the road, thus causing it to fill up hollows and bringing the surface level and even.

It will be noted that we have provided both notches and perforations in the members 32 for the engagement of the locking bolts 34:. The perforations 32 are used in some cases, particularly when both of the scrapers are in use. On a road which is not too stony and where both scrapers can be used for making a double out, the perforations are used for the engagement of the locking bolts as the perforations hold the locking bolts and therefore the scrapers in a steadier manner. On a rough and stony road, however, when only one scraper is used, we find that the notches 31 work to better advantage as by the use of the notches quicker control is secured over the operation of the scrapers and the scraper may be readily set in position so as to extend vertically upward or slanting either forward or back according to the particular exigencies of operation; The supplemental scraper 59 is usually used for making a new road. In this case, the roller 50 is removed and the supplemental scraper is put in place. The supplemental scraper is set vertically under these circumstances and the scraper blade 6 is set in a forwardly slanting position. If the blade 6 be adjusted downward it will cut the ground. If slanted downward and rearward it will drag overthe ground, and if it is slanted forward and downward it will make a deeper out than where it is set vertically. The blade 6 is set vertically when the ground is to be rolled. The object of adjusting the upwardly extending posts 61 is to adjust the supplemental scraper in any position desired. Where a roller is used, the posts or standards 51 for said roller are always placed in a vertical position. In use as a road drag, the rudder side of the machine is so disposed that the rudder will run in the ditch at the side of the road, the scraper ex- &

tending upward to the crown of the road, thus working all dirt and stones toward the middle of the road so as to crown the road. We also find in practice that the roller 50 tends to prevent lateral draft of the machine and keeps the machine always toward the middle of the road.
