PULVERIZER.
SPECIFICATION forming part of Letters Patent No. 308,803, dated December 2, 1884.
Application filed March 3, 1884. (No model.)
lo al?, whom it may concern.-
Be it known that I, WEBsrnR M. ROBERTS, a citizen of the United States of America, residing at Bloomingtomin the county of Osborne and State of Kansas, have invented certain new and useful Improvements in Pulverizers; and I do hereby declare the following to be a full, clear, and exactdescription of the inven tion, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to earth and elod pulverizers; and it consists in the improvements hereinafter described and set forth.
In the accompanying drawings, formingpart of this specification, Figure l is a plan of a pulverizer constructed in accordance with my invention. Fig. 2is asection on the linewx of Fig. l. Fig. 3 is a transverse section through one ofthe gangs ofcutters, and Fig. 4 is a de tail. Y
The frame ofthe machine consists of a metal bar, preferably of a single piece and constructed to form the rear portion, B, parallel `side bars, G, and inclined front bars, D, in-
tersecting cach other at their front ends. A central draftbar,E, is secured to the said metal frame and centrally spans the same, so as to be bolted to said frame at the center of the bar B and at the point (t, formed by the intersecting ends of the front bars. Braces F, arranged parallel with the side bars, O, connect the front bars, D, and rear bar, B, and are secured thereto by means of bolts b.
The machine preferably carries two series or gangsrof cutters arranged on the respective sides of the machine; hence it will only be necessary to particularly set forth one series to comprehend both. Abeam, G, is provided with a series of verti cal perforations, c, through one of which passes a bolt, d, which passes through a curved bracket, c, secured at one end to the upper `side of the frame. The lower end of the bolt d engages an opening therefor in the side bar, C, of the frame, and thus affords a pivotal bearing for said beam G. A hanger, J, preferably cast in a single piece of metal, is secured at each end of the beam G, at the under side thereof, so as to depend therefrom. rlhis casting is of the form shown in Fig. 4, and is provided with a platform, f, at one end, having perforations g for the passage of bolts 7L, which secure the casting to the beam G.
The casting further consists of a shank bi- :furcated at its lower end to form arms j, between which is located a journal-box, K, cou sisting of a block of wood having a journalbearing, k, and retained in position by means of a tongue, k', which rests in a recess therefor in the bifurcated portion of the casting, as clearly seen in Fig. 3. A transverse perforation through the lower portions of the arms and through the journal-box permits the passage of a bolt, 7c?, which secures the lower portion of the journal-box K in position. A series of circular cutters are mounted on a square shaft, I, having a head, Z, at one end, and threaded at its other end to receive a nut, Z. The hubs of the said cutters have square perforations, through which the said shaft passes, so that said cutters and shaft shall revolve together. The end portions of said shaft rest in the `journal-boxes K, a metal bushing having a square opening to receive said shaft being round on its outer face to rest in the bearing and revolve therein with the shaft. Each cutter H is independent of the others, and consists of a hub, m, having a square opening through which the shaft I passes, and each hub carries a series of radialy spokes, oz, which are bent. at their outer extremities, n', to aiford a bearing for the annular blade o of the cutter, which is bolted to said extremities. The blades o and the extremities of the spokes are inclined, as shown in Fig. 8. A series of spacing-spools, p, interposed between the several hubs, maintain the several cutters in their proper horizontal position on said shaft. A metallic loop, q', is formed on the inner casting, J, of each beam G, and is connected to the lower end of a lever, M, fulerumed on a pivot, q, such connection being made by a rod, i'. The draft-bar E carries a segmental rack, N,
with the teeth of which engages apawl, s,
pivoted to the lever M. Each series ofcutters are arranged so that the cutting-edges of one series face those ofthe other series and the center of the machine. By changing the bolt d from one perforation c in the beam G the said beam,with its series of cutters, can be adjusted toward or from the center of the machine. By moving the lever M the inner ends IOO of the bars G are moved rearward on the pivot d, thus presenting each series of cutters obliquely to the line of draft. The arrangement of castings J and the journal-box therein of Wood affords an efficient, light, and durable means for hanging each series of cutters.
The forni and arrangement of the supporting-fra1ne,consisting of a single piece of metal, lends lightness and durability to-the structure and avoids a multiplicity of connections and parts.
I claiml. In a revolving barrow or earth-pulverizer, the frame consisting of a single piece of metal supporting centrally a draft-pole and a seat, in combination with the independent pivoted beams G G, carrying pulveriZing-disks or cutters, said frame having braces F F and brackets e e attached thereto, substantially as shown, and for the purpose set forth.
2. In arevolving harroW or earth-pulverizer, the frame consisting of a single piece ofniet-al supporting centrally a draft-pole and seat, inv combination with `the independent pivoted beams G G, carrying` pulverizing-disks or cutters, said frame having braces F F and brackets c e, and rods connecting said beams G G with an adjusting-lever attached to the draft pole, substantially as set forth.
3. In an agricultural implement of the class described, a frame made of a single piece of 1netal,.having the parallel side portions, C C, the attached braces F F, the central draft-beam, and the pivoted frames G G, carrying a series of cutters, said pivoted frames being attached to the main frames on opposite sides thereofone in front of the otherand provided with means for changiug'the angle of the cutters with respect to the line of draft, the parts being combined and organized substantially as shown, and for the purpose set forth.
In testimony whereof l affix my signature in presence of two Witnesses.
