BLOWING-MACHINE! Specification of Letters Patent.

Patented Mar. 28, 1916.

"ap lication filed April 10, 1912'. Serial No. 689,887.

To all whom it may concern: Be it known that I, J OHN G. Knns'r, a citizenof the United- States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented'new and useful Improvements in Plowing-Machines, of which the followingis a specification. This invention relates to the class of plows and more specifically tothat class of plowing machines which comprise aiplurality of plow blades and which are commonly called gang plows.

An object of this-invention is to provide a gang plow which has disposed thereon a plurality of helical screws which cotiperate withthe plow blades in the manner set forth hereinafter. i Another object of thisinvention is to provide a plowing machinewhich is constructed of but a few parts and one which isdurable, easy to control and eflicient in operation.

VViththe above and otherobjects in view,

my invention relates to such details of con- T is connected with the main frame 1 andstructionand in the arrangement and combination of the several parts as will be hereinafter fully described 1 and specifically pointed out in the appended claims.

In describing my inventionin detail referencewill be had to the'accompanying drawings wherein like charactersdenote like or corresponding parts throughout the several views and in which, i

Figure 1 is a plan view of my invention, the engine and its controlling clutch and lever being-removed for clearness. Fig. 2isa side elevation thereof. Fig. 3 is a plan View of my invention showing the specific means for controlling the engine, in detail. Fig; 4 isafront elevation of my'invention. Fig. 5 is a detail view. Fig. 6 is a detail sectional view of themounti'ng castingfor the plow beams and drive shafts.

Referring'now tothe drawings wherein is illustrated the preferred form of my invention, the numeral 1 designates the main frame, which frame is spanned by the cross pieces 2, the saidfcross pieces being connected by themembers 3. A U-shaped frame has mounted thereon brackets 4 through which brackets extend the shaft 5 as is clearly'shown; The shaft, 5 is supported at each extremity by the traction wheels6 and has keyed thereo'n a gear-'wheel 8, the gear The movement of the lever let occurs when the lever 15 is rocked upon its pivot 16, the lever 14 being engaged by its bifurcated end 17.

For the purposeof supporting the bracket 18 which has journaled thereto the stub shaft 19, the hail20 is swung upon the under side of the frame 7. The stub shaft 19 is supported intermediate its ends by the bracket 21 which is carried upon the standard 22 andis provided at one end with a gear wheel 23 which receives motion from the gear wheel 8. The other end of the stub shaft is supported upon the member 24 by means of the bracket 25 and has thereon a second gear wheel 26 which gives motion to the pinions27 and 28 journaled respectively on the stub shafts 32 and 31. Struck down portions 29 are provided in the pieces 22 and 24 and areprovided with bearings 30 and 30 which support the stub shafts 31 and 32 which carrythe pinions 27 and 28 respectively.

For a purpose hereinafter appearing, blocks 33 are positionedupon the members 3 which blocks have the stub shafts 31 and 32 journaled therethrough, the said stub shafts carrying upon their inner ends bevel gear wheels 34 and 35. The blocks are provided with offset portions36 which receive one end of the rods 37 which carry the bevel gear wheels 38, the last named beveled gear wheels adapted to mesh with those first mentioned as is clearly shown in Fig. 1. Provided upon the blocks are extensions 39 to which are connected the beams-4:8 which point of the plow, thus decreasing the work usually performed by that membern' Gear wheels 43 are provided on the rear ends of the rods 37, the said gear wheels meshing with other gear wheels 44: as shown, whereby motion is given to the shafts 4:5 upon pletely pulverized. The screws 46, act as 82, support the shafts 37 and i5.

draft means to impart a forward thrust and also serve to draw the earth onto the plow blades and the screws are tapered rearwardly to accommodate the contour of the plow blades and so that the screws can extend substantially the entire length of the blades. Thus the screws can be arranged abreast of the plow blade to directly coact therewith. Further, the screws 46 are conned to conform to the shape of the mold boards so as to lie closely adjacent thereto and effectively coact therewith to break up the earth upturned by the shares. Frames 76-77 and 7 8 -7 9, fastened to beams 48, at 8081 and Supporting the plow blades 47' are the beams l8 which are pivoted at their endsas shown and provided with the arms 4:9 which have pivotal connection with the links 50, the said links being operated by the levers 51 which carry pawls 52 adapted to operate upon the segmental racks 53. Pivoted handles 52 are provided upon the levers 51 which operate the pawls 52 as clearly illustrated, the plows and screws thereof being lifted together. r

The rear end of the lever 15 is provided with the handle 54 and is adapted to be held in different positions through the medium of the rack 55 which is mounted upon the cross piece 56 as shown.

The operators seat is supported upon the frame work through the medium of the leaf springs 58 and 59; It will now be readily obvious that the operator within his seat can easily control the different levers above mentioned. I find it'advantageous to provide some eflicient means for guiding the machine in itstravel and to this end the rear of the'frame is provided with a casterwheel 60 which has connection with the bifurcated end 61 of the rod 62' which is insorted in the sleeve 63 as shown. The sleeve 63 is provided with the extension 64: and is adapted to be secured tothe frame work beneath one end of the leaf spring 59. For more securely supporting the rod 62, the members 65 are provided, which members have connection with the same intermediate its ends and with the under side of the frame as shown at 66. A segmental rack 67 is provided 1 upon the rod 62 which rack meshes wit th ie ar.W .68 S pp y P n ling said structure for the 69 in the block 7 O which is supported by the substantiallyUshaped bracket 71. For the purpose--of receiving the sprocket chain 72,

pin 69 is provided with a second gear wheel,

without the" necessity of the operator leaving his post. p 7

It is thought thatthe operation of the machine will be understood from the foregoing description and a detailed disclosure of the same is thought to be unnecessary.

I desireto be understood that I may make slight changes in the construction and combination of the parts of my machine without departing from the spiritof the invention in the least, provided such changes fall within the scope of the sub-joined claims. 7
