RoAD-scR-APER.
forming part of Letters lPatent No. 279,368, dated June 12, I883.
Application filed April 6, 1883. (No model.)
To jall whom it may co a-a I son township, in the county of Allen and State of Indiana, have invented certainnew and useful Improvements in Road-Scrapers, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to, that class known as Wheeled graders and smoothers, and has for its object the grading and smoothing of roadsor irregular land, as will be hereinafter more particularly described. 1
In the accompanying drawings, making part of this specification, Figure 1 represents a plan view. Fig. 2 represents a vertical longitudinal section; and Figs. 3 and 4 detached portions, Fig. 3 being a section in line site, showing the position of the king-bolt with reference to the bolster, the axle, the reach or center piece of the hounds, and the scraper, while Fig. 4 shows one of the levers for raising and lowering the scraper. Fig. 5 is a side view of the end of the pole.
In the figures, A represents an axle, which is mounted upon the two wheels B B.
G 0 represent the hounds of the machine, and D the center bar or reach between the two,- the three parts being firmly secured to the axle A, the hounds being braced firmly from the axle, both behind and before, by the bracesl Z.
Immediately over the hounds is the bolster E. Upon this bolster, near its ends, are secured two angular block's, E E, which are made thicker at their inner than at their outer ends. Pivoted to these blocks, near their outer ends, are two levers, F F, one to each block, in such manner that their ends may have a partially rotary motion.
Secured to each block is a ratchet-segment, m. Beneath the levers F, and between small cars connected to same, are pivoted the L- shaped levers L.
A rod, M, connnected to the short arm of the lever L, connects with a bolt, N, which plays with a coiled wire spring around it through two keepers on the under side of the lever F. The free end of the bolt is adapted to catch into the teeth of the ratchet-segment, and thus station the lever F at any desired said lever.
point. The outer ends ofthe levers F have segments a formed upon them, ,and said segments have in their faces a curved groove.
. A chain, (1, passes through the lever F, near the segment a, and its free end is caught, when desired, in the slot of a plate, 0, secured to V This. chain passes aroimd a pulley, J on the end of the bolster, and then has itslend secured to the scraper. a chain secured to each of the levers F and to each end of the scraper, it is evident that the ends of said scraper can be alternately raised or lowered, or made to work with both ends at an equal elevation or depression.
The scraper proper is composed of three partsthe back board, P, which is made of Wood, the bed-plate g, which is made of metal, and the knife R, which is also made of metal.
The bed-plate may be in one piece, but is pref- 7o erably in sections, which are firmly bolted to the back board, P. y The lower end of the bedplate is provided withtwo shoulders, one in front and the other at rear. The lower end of the back board rests upon the rear shoulder,
and the upper edge of the knife rests against the front shoulder, as seen. The bed-plate is slightly curved'forward at its lower end for the purpose of forming a proper seat and rest for the knife, giving a suitable curve for carrying up the earth to the bed-plate.
G'represents the tongue of the machine,
which is connected to the forward end of the hounds by means of a brace, H. This brace has at its lower end a foot, K, which is perfo- 8 5 rated with holes .to allow of different adjust ments, as will be described. g
r S and T represent two metallic straps, which are connected one to the top and the other to the bottom side of the rear end of the pole. 0'
These straps pass under a yoke, 0, which has its ends secured to the back board of the scraper. The main strap T passes back, and has two rectangular bends in it at its end,
space sufficient being left between the bends 5 to allow itto embrace the semicircle I. This strap is braced and securely connected to the back board by means of a brace, '21. l
I represents a semicircular brace, which is firmly secured at its ends to the back board of the scraper near its ends. This brace I is provi de with a series of holes, and apiu, '(0, passes There being 6 Y represents the king -bolt.
through the bent ends of the strap T, and also through the semicircle I, for the purpose of securing the two parts together. By removing the pin 10 the bent end of strap T may be shifted upon the semicircle for giving direction to the draft of the machine through the pole.
a represents a brace, which passes from near the bottom of the back board to the strap T, near its rear end, being securely bolted to the strap and suitably hinged to the back board, which enables the rear end of the strap to move on the semicircle I, .while at the same time the scraper is suitably braced all the while. The brace 10 is also hinged, as seen, to the back board of the scraper.
W hen the scraper is centrally located the king-bolt passes down through the bolster, the center piece of the hounds, the axle, and then through the yoke c, all as seen in Fig. 3; but the scraper is capable of being changed in position endwise of the axle, and held in that position by the king-bolt, as will 110w be explained.
Two metallic plates, 2, (partially seen'in Fig. 1,) are secured to the axle A, one on its upper and the other on its lower side, and in this instance a short distance to the right of the center of the axle. These plates are provided with suitable holes for receiving the kingbolt.
NVhenit is desired to change the position of the scraper the king-bolt is removed and the bolt removed from the foot K. The bolster is then shifted to the right until its hole for receiving the king-bolt is over the holes in plates z. The king-bolt is then dropped in place, and the foot K is again bolted in proper position on the tongue, while at the same time the plate T may be suitably changed on the semicircle I.
9 represents a cutter secured to or forming a part of the knife at one end. This cutter extends slightly upward and outward from the knife, and may be made to cut a path for the wheel, while its obliquity draws in the earth from beneath the wheel to the scraper.
\Vhen the scraper is intended to run directly under the axle or square across the machine, the king-bolt will pass down through the center of the axle; but when it is desired to have it move obliquely, or one end forward of the other, the king-bolt is shifted over to pass through the plates 0 represents a foot-piece for the driver of the machine, and is bolted upon the semicirele and in front of the drivers seat, as seen.
The end of the tongue is provided, as seen in Fig. 5, with a metallic rod, which serves as a keeper for the neck-yoke ring. This rod is bolted upon the top and to the bottom side of the pole, and a sufficient space is left between it and the end of the pole for the neck-yoke ring to pass around the end and work with above or below it, as may be required.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The bolster E, capable of being detached and adjusted to different positions upon the frame of the machine, and carrying with it the means for connecting it to and operating the scrapers, consisting of the levers F, chains a a, and pulleys J J the several portions being constructed and arranged substantially as set forth.
2. The semicircular brace I, connected to the rear of the scraper, in combination with the tongue having a rear adjustment at w and a forward adjustment by means of the brace H, substantially as set forth, and for the purpose specified. 8. The scraper composed of the back board, 1?, the bed-plate q, and the cutter R, braced from the rear. by means of the braces u and u and-semicircular brace I, substantially as and for the purpose set forth.
4.. The tongue G, provided at its rear end with the straps S and T, in combination with the scraper, the yoke t, the brace a, and the semicircular brace 1', arranged in rear of the axle, substantially as and for the purpose set forth.
5. The combination of the scraper with the plates 2 on the axle, the tongue G, as constructed, and with its brace H and the bolster at one end and bolted to the tongueplates near their rear end, substantially as and for the purpose specified.
In testimony whereof I aflix my signature in.
