SIDE-DRAFT ATTACHMENT FOR ROAD=GRADERS.
Specification of Letters Patent.
Patented May 7, 1907.
Application filed March 20,1905. Serial No. 251,146.
T0 at whom it may concern:
Be it known that I, THOMAS F. BRYAN, a citizen of the United States, residing at Ponca city, in the county of Kay and Territory of Oklahoma, have invented new and useful Improvements in Side-Draft Attachme'nts for Road-Graders, of which the following is a specification.
My invention relates to side-draft attachments for blade-road-graders, in which a chainis attached to the side of the grader at or near the rear thereof, the said chain extending forward and outward being maintained at the desired angle by a longitudinally adjustable brace-bar having its outer end attached to said chain and its inner end attached to the side of the grader; and two rods having an intermediately connected spiralspring attached to the outer end of the said brace-bar and the upper central portion of the grader frame-work having attached thereto a second spiral spring rod, and at taching members all of which will, hereinafter, be more fully explained.
The objects of my invention are; first, to provide means to facilitate the moving of earth up an incline by blade graders; second, to prevent the grader from upsetting; third, to prevent the grader from crawling in loose earth; fourth, to prevent the rear grader-wheel from climbing the bank; fifth, to enable the operator to make a clean furrow; sixth, to reduce friction and lighten the draft; seventh, to save time and labor. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a view in perspective of a blade grader in operation, having a side-draft attachment embodying the elements of my invention; Fig. 2 is a view in perspective of the brace-bar and its connections; Fig. 3 is a sectional elevation of the brace-bar; Fig. 4 is a view in elevation of the locking eye-bolt attached to a section of the grader arch-beam. Fig. 5 is a plan view of a section of the archbeam and the brace-bar as in working position.
Similar letters refer to similar parts in the several views.
In the drawings A is one of the twin archbeams of the grader, B is the circular swivel frame to which the twin blade-beams are attached (only one C being shown), a is the chain, used in the present case though an adjustable rod may be used instead thereof, the
freedom of movement and security of position to the said brace-bar, a lockeye-bolt 6 having an inverted U extension 6 is passed through and secured to the flange of the archbeam A at a point adapted to maintain the brace-bar at a right-angle (or nearly so) to the line of the grader.
Near the outer end of the brace-bar two vertical holes are provided adapted to re ceive the staplef for the purpose of securing in position the draft chain a, and to the bow of said staple is attached one end of the brace-bar support consisting of rods 8 s attached to the spiral spring 8 the upper end of support rod 8 being attached to the upper central portion of the grader frame-work rods, 8 s and their intermediately connected spiral spring .9 being to prevent the outer end of thebrace-b ar from dragging upon the ground while the grader is being turned about, or when the chain is slack.
While the mode of attaching the side-draft attachment to road-graders is shown upon one side, only, the same method is repeated upon the opposite side of all reversible blade graders, of which there are a number in use, differing materially in construction, to all of which my side-draft attachment is adapted. The mode of attachment may of necessity differ in each case, the material point being to attach the draft chain at or near the rear por tion of the side or to the end of the grader and attach the brace-bar to some convenient portion of the frame work of the grader, and, 1
at a point enabling the said brace-bar to be, proximately at a right-angle to the line of the grader; the place of attachment should be sufliciently strong to withstand the strain when the line of draft is at an outward angle, more or less acute, as when the grader is moving earth up a steep incline.
To prevent the draft chain, when slack, from contact with the wheel or ground the spiral spring a is secured to the frame work of the grader and to its opposite end is attached a rod 41/ secured to the said draft chain. The upper end of the brace-bar support 8 s and 8 may be attached to any portion of the grader best adapted to secure the purpose.
Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent, is-
1. In combination with a blade-roadgrader, a side-draft attachment consisting of a draft-chain and a brace-bar having an outwardly extending end attached to said chain and a brace-bar support consisting of rods 8 3 having an intermediately connected spiral spring 8 substantially as described.
2. In combination with a blade-roadgrader, a side draft attachment consisting of a draft-chain and a brace-bar having an outwardly extending end attached to said chain a brace bar support, consisting of rods having an intermediately connected spiral spring and a chain supporting rod and spiral spring at and a substantially as described.
3. In combination with a blade-roadgrader, a side-draft attachment consisting of a draft-chain and a brace-bar having an outwardly extending end attached to said chain a brace-bar support, consisting of rods having an intermediately connected spiral spring, a chain support consisting of a rod and spiral spring and a staple bolt (1 passing through,
laterally, and secured in the brace-bar 0 near its inner or grader end substantially as described.
4. In combination with a blade-roadgrader, a side draft attachment consisting of a draft-chain and a brace-bar having an outwardly extending end attached to said chain a brace-bar support, consisting of rods having an intermediately connected spiral spring, a chain supporting rod and spiral s ring, a staple bolt passing through, latera ly, and secured in the brace-bar near its inner or grader end and a lock eye-bolt having its upper portion terminating in an inverted U e 5. In combination with a blade-roadgrader, a side-draft attachment consisting of a draft-chain and a brace bar having an outwardly extending end, a brace-bar support a staple bolt passing through, laterally, and secured in the brace-bar near its inner or grader end, a chain support, a lock eye-bolt having its upper portion terminating in an inverted U and a hook a attached to the rear portion of the grader, all substantially as described and for the purposes set forth.
In testimony whereof I afiix my signature, in presence of two subscribing witnesses.
THOMAS F. BRYAN.
