EDDINGSTON, OF PORT ARTHUR, JEFFERSON COUNTY, TEXAS.

cLaY-meeme MACHINE.

Application filed April 22, 1920. Serial No. 375,837.

T 0 all whom it may concern:

Be it known that I, JAMEs'T. PoxoRNY, citizen of the United States, residing at Cedar Bayou, in the county of Harrisand State of Texas, have invented certain new and useful Improvements in a Clay-Digging Machine, of which the following is a specification. I i

This invention relates to new and useful improvements in a clay digging machine.

One object of the invention is to provide a machine of the character described which isspecially adapted for the purpose of digging clay to be used in the formation of brick, tile and the like.

Another object ofthe invention is to provide a machine of the character described by means of whichclay of a character adapted to be used in making'brick, tile and the preparatory to molding the same.

Another object of'the invention resides in the provision of means whereby the machine may be propelledalong a track in either direction; so as to-"bring the saws against the work.

With the above the inventionhas particular relation to certain novel featuresfof construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings wherein,

Figure 1 is a plan view of the machine, Figure 2 showsa side elevation of a pair of beveled pinions employed in connection fixed upcnthe shaft 17 and operating over .with the means for shifting them,

Figure 8 shows a side view ofthe machine and i Figure4 shows atransverse sectional view taken on the line 4, gt of Figure 3.

Referring now more particularly to the drawings wherein like numeralsof reference designate similar parts in each of the figures, the numerals 1, 1 refer to the rails of a stationary track. The numerals 2, 2 designate the rear tractor wheels which are flanged in the usual way to travel along said track. Front carrier wheels are also provided, but are not shown in the drawings. The tractor wheels 2 are fixed upon the respective ends of an axle 3 which is rotatable in the bearings 1, 4 and fixed upon said axle is a sprocket wheel 5. Mounted upon the fr nt and re r axles is a frame Work 6 which like, may be dug and partially pulverized,

and other objects in view,

supports the motor 7. This motor has the usual drive shaft 8 and fixed upon one end thereof there is a pulley 9 over which the dr1vebelt10 operates. Rotatably mounted in suitablebearings 11, 11 carried by the opposite side of the frame work there is a counter shaft 12 and fixed thereon isa pulley 13 over this belt thebelt 10 operates, and through which said pulley is driven. The shaft-s 12 has a spool 14 splined thereon,

whose respective ends are formed with beveled plnions 15, 15. Rotatably mountedin sultable bearings 16, 16 carried bythe frame work, and extending at right angles to the shaft 12 there is a shaft 17 whose forward end has the beveled pinion 18. A manual lever 19 is provided which is connected to the spool 14L and through which said spool may be shifted to bring the pinions 15 into mesh with the pinion 18 alternatively. Fastened to the adjacent side of the frame work there .is a bracket 20 formed with three notches as 21 which are spaced apart. When the spool 14: is shifted into any particular position the lever 19 may be engaged in the corresponding notch 21 to hold said spool in set position. When one of the pinions 15 is in mesh withthe pinion 18 the shaft 17 will be driven in one direction and when the other pinion 15 is in mesh with said pinion.

from the motor. Aligned with the sprocket wheel 5 there is a sprocket wheel 22which is said sprocket wheel there is a sprocket chain 23throughwhich the rear axle 3 is driven and by means ofwhich the entire machine I may be propelled along said track either forwardly or reversely. U

Rotatably mounted in suitable bearings 24, 24 carried by the side of the frame work there is a counter shaft 25 which is in alignment with the shaft 12 and which is arranged to be clutched therewith and unclutched therefrom through the clutch 26.

which is controlled in the usual way by means of the clutch lever 27. The outer end of the shaft 25 has a spool gear 28 fixed thereon.

A boom is provided which is formed of the channel irons 29, 29 spaced a suitable dist n apart and tied t gether by means of suitable cross bars 30. The .inner ends: of these channel irons have bearings on the shaft 25. The spur gear 28 is in mesh wlth a. larger spur gear wheel 30 which is fixed upon the corresponding end of transverse shaft 31 which is rotatably mounted in suitable bearings in the side members of'said boom and there is a roller 32 fixed upon the shaft 31 between said sidem'embers. At the free end of the boom are the bearings 33, 33 in which the free shaft 34 is rotatably 'mounted and fixed upon this shaft between the side members 29 there is a gang of pulverizing saws 35. FiXed upon one end of the shaft 34 there is a pulley 36 which is in alignment with a similar pulley 37 which is fixed uponthe end of the shaft and operating over these pulleys and transmitting rotation from the latter to the former there is a belt 38 through which the saws are r0- tat'ed. Fixed upon the other end of the shaft 34 outside of the corresponding side member -29'there is a digging-saw 39 which operates against the breast of the Work and cuts the clay loose and delivers it within the reach of the gang saws by means of which the clay is pulverized.

Fastened to the respective side members 29, 29 areth'e side plates 40, and 41 which depend below the boom and which have the respective bearings 42, 42 in which the transverse shaft 43 rotates. This shaft has roller 44 fixed thereon and a bent conveyor 45 op erates over the respective rollers 32-and 44. The outer end of this conveyor is arranged closely adjacent the gang saws underneath and the pulverized clay is delivered on tosaid conveyor by said saws and is carried upwardly by the conveyor and discharged into the depending hopper 46 which is secured to the adjacent side of the frame work and which delivers the material on to a suitable conveyor as 47 by means of which the n1aterial is delivered to the desired place. Upstanding from the side of the frame work, adjacent the boom, are the standards 48, 48

which are spaced apart and between the up-per'ends of which the lever 49 is pivoted. Oneend of'this leveris connected to the free end of the boom through the link 50 and the other end thereof has a counter balance weight 51 attached thereto.

The standards- 48. are suitably placed. by

means of the braces 52, 52 which are fasjtened at their lower ends-to the framework and at their upper ends; to the respective standards. These braces have suitable aligned bearings in which the shaft 523 ro tates and fixed upon said shaft between said braces is a drum, 54 a cable 55 is wound around the drum and has its respective ends secured to the lever 49 on opposite sidesof 'rotatably mounted at the free end of said boom, ad-ig ging saw spaced from said pul w 'erizing saws, an operative mechanism carried bythe frame work through which said saws may be driven,- means for elevating and lowering 'the same, dep'endingsi'de' plates carried by the boom, an endless belt moving between the side-plates, said belt and plates forming a conveyor dispose'dto receive from said saws. r r 4 2 A device of the character described includin a framework, a boom pivoted thereto at one end, a gang of saws rotatably mounted at the" free end-offsaid boom, an operative mechanism carried by the frame work through which said saws maybe driven, dependingside plates carried by the boom, an endless belt between said plates I driven by said mechanism and forming with said plates a conveyor arranged to receive the material from the saws, a delivery conveyor disposed to receive from the first mentioned conveyor, and a hopper through which the material is? discharged from the former conveyor to the latter.

*In testimony whereof'l have. signed my name to this specification in the presence of two subscribing witnesses. 8
