MGHINE FOE GBLATING METAL TURNINGS AND BORINGQ.
Application filed tune-80, 1920. Eeriel Ito. 398,1.
To all whom it my concern:
Be it known that I, Enwm K. HILL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and a State of Ohio, have invented certain new and useful Im rovements in Machines for Granulatin etal Turnings and Borings, of which t e following is a specification.
This invention relates to a mill for grindto ing or reducing to chips the cast-d material resulting from turning or boring metal products, more particularly to a machine for anulating the miscellaneous masses of shav- 1n s that issue from a metal turning lathe. 16 %."he cast-oil material from lathea. and boring machines, is commonly known as scrap and is sold to foundries, to be recast. When this material is deposited in the cupola of a furnace, in a loose state, as there is a large percentage of waste, as more or less of the material will burn and not fuse. If, however, the material is in a compact mass it will fuse with comparatively small loss. In view of this, means have as been provided for com ressing this class of scrap into extreme y compact or, substantially solid blocks or billets which when deposited in a furnace, melt substantially the same as solid metal, with a small per centage of loss. As a matter of course this treatment enhances the value of scrap metal of this character. The means devised for this purpose provides powerful presses for forming the loose material into the compact billets, and the feeding of the loose bulk of miscellaneous material to the press has heretofore been a difficult, expensive, and dangerous proposition. The lathe turnings being of spiral ribbon formation, of varying lengths, and different degrees of flexibility and resiliency, and being tangled and intermingled in a miscellaneous bulk, ofier stubborn resistance to the loading of the press pre aratory to the compressing operation.
he primary object of the present inven tion is to produce a machine for the treatment of a miscellaneous bulk of scrap metal including turnings, borin and the like, whereby the tangled resilient features are so eliminated and thebulk reduced to a docile mass.
In the realization of this main object, I
provide a mill structure embodying feedmg mechamsm, conveyors, and coacting cutt ng or shearmg elements of novel construct1on and arrangement, and owing to the character of the material treated, the operatlng elements are subjected to more or less strenuous usage, therefore a further objpect'of the invention is to provide for the sharpening of the cutting or shearing parts, and the removal and replacement of 1111111 members which become worn.
W1th these and other apparent objects in view the present invention consists in the construction, combination and arrangement of elements, as hereinafter described and po nted out definitely in the appended claims, reference being bad to the accompanyingdrawings which are made part of the specification, similar characters of reference being employed to designate corresponding parts.
In the drawings Figure 1 is a side eleva t1on of an embodiment of the invention.
Fig. 2 is an end elevation, viewed from the right of Fig. 1.
Fig. 3 is a longitudinal section taken on line 3-3 of Fig. 1. Fig. 4: is a vertical section on line 4-4 of Fig. 2.
Fig. 5 is a fragmentary section on line 5-5 of Fig. 4, with a hood member removed.
Fig. 6 is an inside view of the end plate with a single shearing plate attached.
Fig. 7 is a section on line 77 of Fig. 1. Fig. 8 is an outside view of the end cap, illustrating a modified adjustable attachment of shearin lates, and Fig. 9 is an edge view of sai p ates.
Fig. 10 is an end elevation of a machine embodying the principles of the'invention in a modified form. i
It will be understood that the following s ecification and the drawings associated t erewith set forth an embodiment involving the principles of the invention and that in the development of the improved machine I am not confined to this specific construction, various changes in the details, including the general design, proportions, combination and arrangement of arts, and construction of individual mem ers, are allowable without departure from the spirit of the invention or the scope of the claims.
In the simple embodiment, as illustrated,
)1 represents the body of the machine or a housing for the operating mechanism For convenience of assembling, the housingis divided horizontally, the upper member i coacting with the support 1 and forming a chamber 2, and the cap 1 in GOIIljllllCblDll with said support, providin. a "ournal box.
for the aeratingl shafts hopper t is provide, said opper being attached to the member 1 and opening into the chamher 2 through the neclr 29. The shafts 3 extend longitudinally into the chamber 2, the extended portions 3 being squared and carr 'ing spiral conveyor members 5. The shade 3 are simultaneouslydriven 1n opposite directions by companion spur gears 50 and 51 which are keyed or otherwise fixed on the o erating shafts 3, said gears being actuatef by .a motor-:not shownthrough-the medium of a plmon 52.
time or more knives 6 are attached to each of the holders 7, said holders being mounted on the members 3 at the terminals ofthe conve ors 5, and rotated by said members 3 plate 8, provided with peculiarly shaped openings 8 which have sharp or shearing edges, is attached to the inner face of a head member 9 which forms the outer end wall of the chamber 2. Said member 9 is provided with openings 9" that register with the openings 8 in the shear plate 8.
The knives 6 bear on the plate 8, and when rotated they coact with the openings 8 and perform a shearin function.
A transverse shaft 11 is mounted in suitable bearings 12 on the outside of the hopper d. Said shaft is driven by a train of bevel gears 13, 14, 15, 16, 17 and 18, suitably mounted and coacting with the driving gears 50 and 51.
The shaft 11 carries-a plurality of radiating arms 11, preferabl curved as shown. These arms extend into t e hopper 4L throu h a plate 19 provided with slots 19*. 'l e function of the rotating arms 11 is to engage the 'miscellaneous material in the hopper and carry it into the chamber 2 where the spiral conveyors 5 receive it. The material isdisengaged from the arms 11 by the late 19 as said arms recede from said plate tlirough the slots 19.
It is desirable that means be provided for adjusting the shearin members to compensate for wear, but as filere are various ways of accomplishing this function I claim this have s .vides for the interposition aceaeci simple operative means for the adjustment oft e shearing member 8.
ofone or more filler plates 20 between the member 8 and the outer cap 9. In the modification shown in Figs. 8 and 9 two shearing plates 80 are employed. Sai plates are provided with dowels 80 which function in seats 9 in the cap 9, and set screws 21 threaded throu h the cap 9 bear on the plates 80 and provi e for the adjustment of said plates. I
Fig. 10 illustrates, in end elevation, a machine in which is embodied a sin is spiral conveyor. It is not deemed advisa le to encumber the present specification with a description ofthe construction and operation of t is embodiment, as it would be merely a repetition of what has already been set forth, with the exception of that part which relates to the coaction of two spiral eonveyors. The reference numerals applied to Fig. .10 designate elements that are the equivalent to the elements correspondingly desiated in the figures illustrating the double conveyor type.
While l have shown and described an operative mechanism embodying a dual conveyor mechanism, and have mentioned a sin is conveyor type of hine, it will be an erstood that, according to the spirit of the inventiomand the scope of the claims, there may be a batte of any desired number of conveyors a! coactin mechanism va ing from that a cifically escribed.
ll' hat ll claim if desire to secure by Letters Patent is; v

In a machine for nulating miscellaneous metal shavings, lathe turnings, borings, and the like, a housing providing a chamber, a s iral conveyor menu to opcrate longitu inally in said chamber, longitudinally extending ridges in said chber outer end wall of the chamber, cutting blades bearing on the inner face of said end wall, means for conjointlg rotating said blades and spiral conveyor so t at the edges of the openings in the end wall coact with the blades for shearing the material conveyed to said openings.
