8% A; a? g Inventor j A Q 8 5 By Allorney Patented Aug. 9, 1932- ALBIN DE BOURG, OF BONNER, MONTANA ANVIL FOR FUEL HOGGERS Application filed March 3,

This invention relates to an anvil for fuel hoggers or for a machine for grinding up slabs and all kinds of scraps, the general object of the invention being to make the anvil in such a manner that the cutting plate or blade can be readily and quickly adjusted to take up wear, so that the anvil will last for along time and when it is necessary or desired the cutting blade can be removed and replaced by a newone with but little effort, and as the blade is a comparatively small one, and it is simply necessary to replace the blade and not the entire anvil, the cost of replacement is very small.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described and claimed, illustrated in the accompanying drawings, and specifically pointed out in the appended claim.

In describing the invention in detail, refer ence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation with the parts broken away and showing a hogging or wood grinding machine to which the invention is applied. a

1,-the wood grinding machine is used for grindmg slabs and all kinds of scrap wood, generally at saw mills, and this produces what is called hog fuel and is generally referred to as a fuel hogger, andcomprises the housing A into which the wood is introduced through the member B and in which housing is the rotary cutting member shown generally at C which cooperate with a pair of anvils D, these anvils being-carried by the removable sections E of the housing, which are hingedly connected, to the main part of the'housing at F. All of these parts are of well known :con struction-and my invention relates to the anvils D. i

Heretofore these anvils have been formed of chilled steel so that they wear quickly and they are each formed of a single piece so that when they do wear out, the entire plate or piece is promptly removed and substituted by a new one.

In carrying out my invention, I form each anvil of a plate 1 having a recess 2 in one face thereof, which extends from one end of the plate to the other at a point Well below the top of the plate, through the lower edge of the plate, and the lower wall of the recess is beveled as shown at 2 to form a seat for the blade 3 which is in the shape of a rectangular bar and of such a width that the upper edge of said bar will extend into the deeper part of the recess so that said upper edge can be engaged by the enlarged parts lef the rods 5 located in the vertical grooves or bores 6 in the plate 1 and arranged inwardly of the res cess 2 and having portions incommunication with-said recess as shown in Fig. 6.

The upper end of each rod '5 isformed with a threaded part 7 for engaging threaded openings 8 in the plate. Each opening forms a continuation of the bore 6 and each rod 5 is formed with a head 9 which is located in an opening 10 formed in the top of the plate. A strip 11 is fastened by the screws 12to the top edge of the plate, and cover the openings 10, and the heads 9 of the rods 5. A clamping plate 13, is connectedwith the plate 1 by the bolts 14, the major portion of the clamp ing plate resting in the recess 2 and said plate 13 is provided with a clamping part 13 for blade can be removed and a new one clamping the blade 3 against the seat 2' when the bolts 14 are tightened.

The outer face of the plate 13 is of arcshape in cross section as shown. The inner face of the plate 13 is substantially fiat and it is formed with the small recesses 15 for receiving portions of the enlargements 4 and the threaded portions 7 as clearly shown in Fig. 9.

The heads of the bolts 14 fit in recesses 16 formed in the outer face of the plate 13, and large circular recesses 17 are formed on the outer face of the plate 13 for receiving the nuts 18 on the bolts 19 which connect the'anvil to the supporting member 20 of the machine, the heads of the bolts 19 fitting in the substantially bayonet-like slots 21 in said member 20 as shown in Fig. 10. Thus by raising the anvil, the heads of the bolts 19 will be free of the small portions of the slots 21 so that they can be passed through the large parts of the slots to free the anvil from the supporting member, but when the heads of the bolts 19 are in the small parts of the slots 21 the anvil will be securely locked to the member 20. f

From the foregoing, it will be seen that by opening either one ofthe movable sections E, the heads of the bolts 9 are exposed so that the bolts or rods 5 can be turned to cause the enlargements 4 to press upon the upper edge ofthe blade 3 afterthe bolts 14 are loosened to adjust the blade downwardly so as to take up wear of the exposed edge of the blade;

The bolts 14 are then tightened to cause the clamping plate 13 to clamp the blade in adjusted position. When the wear of the blade is such as to necessitate its replacement by a new blade this can be easily and quickly done by removing the clamping plate 13 or loosening the bolts 14 thereof so that tho ollod su stituted therefor.

Then the bolts 14 are tightened to cause the plate 13 to clamp a new blade in position.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes'may be" with the lower edge of the plate beveled to engage the blade to hold the blade upon its seat, a plurality of bolts threaded in the upper part of the first plate and having their lower ends engaging the upper edge of the blade whereby turning movement of the bolts will adjust the blade downwardly, means for detachably connecting the anvil to its supporting member, such means comprising headed bolts passing through the anvil member, and said supporting member having bayonet slots therein for receiving the heads ofthe bolts.

In testimony whereof I affix my signature.

ALBIN DE BOURG.

made in the construction and in the combinatron and arrangement of the several parts, I

provided that such changes fall within the scope of the appended claim.

Having thus described my invention; what I claim as new is A11 anvil for a fuel hogger comprising a plate-like member having a recess in one face thereof which extends from one end of the plate to the other with the lower wall of the I recess sloping downwardly and outwardly to form a seat, a blade resting on the seat, a clamping platevbolted to the first-mentioned plate and having a portion seated in the recess
