GRlNDING-MILL.
SPECIFICATIONforming part of Letters 'Application iled J une 2l, 1897.
To @ZZ whom it may concern:
Be it known that I, THOMAs CASOADEN, Jr. a resident of Waterloo, in the county of Black Hawk, State of Iowa, have invented certain new and useful Improvements in Grinding- Mills, of which Ido declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
The present invention has relation more particularly to improvements in that class of grindinglmills commonly known as feedgrinders, such mills being more especially adapted for the grinding of corn or other grain to be used as food for stock.
The invention has for its objects to so improve the construction of the mill that the friction of the parts shall be reduced to a minimum, to increase the capacity, efficiency, and durability ofthe mill, to provide improved means whereby the grinding rings or surfaces of the mill shall be more completely under the control of the operator, and in other respects to render the mill more effective and durable than any other construction of feedgrinding mill with which I am familiar.
With these objects inview the invention consists inthe various novel features of construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end ofl this specification.
Figure l is a view in central vertical' section through a grinding-mill embodying my invention. Fig. 2 is a view of the mill in side' elevation, the outer grinders at the base of the mill being shown in vertical section. Fig. 3-is a plan view. Fig. 4 is a view in horizontal section on line 4 4 of Fig. l. Fig. 5 is an inverted plan view. Fig. 6 is an enlarged detail View showing the manner of holding the lower set ofantifriction-balls in place. Fig. 7 is aview in central vertical section'through Fig. 6,. Fig. 8 is an inverted plan view of the ring whereon the'lower set of antifriction-balls are sustained. Fig. 9 is a plan view; and Fig. yl() is a view in vertical crosssection'upon anenlarged scale, showing the manner of holding the upper set of antifric- Patent No. 604,853, dated May 31, 1898. Serial No. 641,557. (No model.)
The base A of the mill is provided with suitable lugs or feet a, whereby it may be bolted to the receiving-box or other convenient support. The outer surface of the base A, which is of conoidal shape, constitutes the inside rin g of the inner set of grinders,and from the base A rises the cone B, from the .apex of which extends the post B, the post B being preferably cast in piece with the cone Bu. The upper surface of the cone B is formed with crushing-teeth b in suitable number and arrangement and adapted to coperate with corresponding teeth c, that depend from the arms O, that are preferably formed integral with and extended inwardly from the outer shell O of the mill, these arms O being inclined in correspondence with the inclination of the cone B.' To the top of the shell C is connected the hopper W,into which will be placed the material to be ground. The inner ends of the arms C are united and preferably integral with a ring O2, that encircles the conepost A'. At the base of the cone-post B is formed a shoulder b2,upon which rests a ring D, that is preferably formed with pockets or open spaces'cl (see Fig. '7) to receive the bearing-balls E, these balls E being of such diameter as to extend outside the pockets of the ring D and bear against the outer face of the cone-prost B and againstthe innerrface of the ring O2, that encircles the cone-post. The purpose of the ballsE is l to avoid the frictionincident to theweight ofthe shell O V and connected parts, and aswell, also, of the sweep that will be attached to the shell by means of the laterally-projecting studs c2 in manner well understood in the art. One function of the ring D which I prefer-to employ, but which is not essential to the broad features of my invention, is to so space the balls that the necessity is avoided for providing balls around the entire base of theconepost, thus making it possiblel to use cornparatively few balls. Another function of the ringD is to guard the bearings of the balls E against access thereto of thebody of grain within the machine. By preference theuunder surface of the ring D is formed with a series of teeth d', preferably of the shape shown in Fig. 8 of the drawings, these teeth IOO j', whereby the ring J is held in place.
serving to carry outward any iine dirt, feed, or the like that may collect around the conepost over the shoulder b2 at thebase of the cone-post and deliver it onto the surface of the cone B,whence it willpass to the grindingrings, as will hereinafter more fully appear.
The ring or hub C2 at the inner ends of the arms C has a portion extending over the balls E, and upon this portion of the ring C2 rest the bearing-balls F, upon the upper surface of which balls bears a ring or hub G, from which extends the cob-crushing arms G', the hub or ring G being formed with a square or like polygonal socket to fit over the correspondingly-shaped upper part of the cone-post B', so that the ring G and arms G' will remain stationary or rigid with the cone-post. Preferably the balls F are held within pockets formed byarms 7L, see Fig. 9,) that project inwardly from a ring H, that rests upon the upper face of the ring or hub C2, the purpose of this ring H being to so space the balls F that the necessity of employing a great number of balls is avoided, and, furthermore, to prevent the passage of the feed or grain onto the surface of the balls and their bearings. The outersurface ofthe cone-base A is formed with a series of vertically-disposed grinding-teeth d', opposite the lower portions of which is set the grinding-ring J', that will eo- Operate with the inside teeth ct' in grinding grain. Preferably the grinding-ring J is set within an annular recess c, formed around the lower portion of the shell C, the bottom of the shell and the bottom of the ring J being provided, respectively, with outwardlyextending flanges cj and j to receive the bolts On the outside of the shell C, at its base, is mounted the inner ring K of the outer grinders, this ring K being preferably of the shape shown and having its lower edge connected by the bolt j' with the flanged base of the shell C. The outer surface of the ring is formed with teeth that cooperate with teeth formed upon the inner surface of the outer ring K' of the outer grinder. This outer ring K' is connected to the lower portion of its annular easing M by bolts m, that pass through the flanges 'nt' and 7a4 at the base of the casing and of the ring K', and through these flanges extend the bolts O, that connect with the bracket P, whereby the adjustment of the outer grinding-ring is effected. The bolts O extend loosely through holes formed in the feet a. The shell C is provided with a series of openings c7, by which grain will pass outward into the space between the rings K and K' of the outer grinder.
By reference to Figs. l and l of the drawings it will be seen that casing M is provided upon its interior with a series of Wings m3, the purpose of these wings being to receive the grain as it passes through the opening c7 and force it downwardly between the rings K and K of the outer grinder. The hub p of the bracket P is provided with an opening p', at the top of which is formed a seat to receive a threaded nut P', through which passes a temper-screw R, this screw R being provided with an annular shoulder fr, adapted to bear against a anged collar R', that enters and bears against the central opening formed through the cone-post B'. The upper portion of the temper-screw R is screw-threaded to receive ahand-wheel S, that is provided with the depending collar s, that bears against the upper face of the hub or ring G, and at the upper end of the temper-screw R is fixed a hand-wheel T, whereby the screw may be turned.
From the foregoing description the operation of my improved mill will be seen to be as follows-viz., the material to be ground (such as ear-corn or the like) will be placed within the hopper NV and rotation will be imparted to the arms C from the sweep that will be attached to the studs c2 in the usual manner. Inasmuch as the cob-breakin g arms G' are fixed to the cone-post B', these arms G' remain stationary, while the arms c beneath them are revolved and cobs or like coarse material will be crushed and broken between the arms G' and C and will pass down onto the face of the cone B. The preliminary crushing or grinding of the material will occur between the teeth upon the under side of the arms C and the corresponding teeth upon the upper face of the cone B, and a portion of the material will then pass downward between the inner and outer rings of the inner grinder, while a portion of the material will pass through the holes c7 and down between the inner and outer rings K and K' of the outer grinder. As the material passes through the hole c7 it will be forced downward by the wings or deflectors m3, and after passing between the inner and outer grinders the material will descend into the receiving box or bin beneath the mill.
By means of the temper-screw R and handwheels S and T an independent adjustment of the inner and outer grinders can be effected. By turning downward the hand-wheel S, the sleeve s of which rests upon the top of the cob-breaker, the cob-breaker, the arms C, and the shell C' will be forced downward, thereby bringing the outer grinding-ring J of the inner grinder nearer to the inner ring of the inner grinder, thereby causing the inner grinder to more Iinely grind the material. On the other hand, by turning upward the hand-wheel S the grinding-ring J can be lifted, so as to separate the inner and outer rings of the inner grinder in order to permit a coarser grinding by Such rings. By turning downward the hand-wheel T the temper-screw R can be forced downward, thereby causing the outer easing M and the outer grinding-ring K' to approach nearer to the inner grinding-ring K of the outer grinder and cause a finer grinding of the material at such point, and when the IOO IIO
' hand-wheel T is thus turned to adjust the outer grinder the hand-wheel S should be turned with'it, so as to avoid disturbing the adjustment or relation of the rings of the inner grinder. It is obvious that if the handwheels T and S be oppositely turned the outer ring of the outer grinder will'be loosened, thereby permitting it to be raised by the force of the grain being crushed. Y
It will be observed that the inclination of the grinding-rings of the inner and outer grinders is different-that is to say, the rings of the outer grinder more nearly approach the vertical or axis of rotation than the rings of the inner grinder, and hence it is seen that in this way the outer grinding-rings can be forced together sufficiently for fine grinding or can be allowed to spread open for coarse grinding'without materially affecting the adjustment of the inner grinder. If the rings of the outer grinder were set upon the same angle as the rings of the inner grinder, there would be danger of the pressure on the outer grinder forcing the rings of the inner grinder together, which by my construction is entirely avoided.
Inasmuch as there is a tendency of the grinders to open and separate in grinding, by reason of the hardness of the grain that is being crushed, these grinders must be held iirmly and forcibly together, and in prior constructions of mills this has caused a great amount of friction, requiring much more power in the operation of the mill and much more severe wear of parts than with my improved mill, since by my present invention the bearing-balls E and 'F relieve the parts between which they are interposed from friction incident to holding ythe parts firmly together and incident to the pressure caused by the lateral strains of the sweep whereby the rotation of the mill is eiected.
It is manifest that the details of construction above set out may be varied within wide limits without departing from the spirit of the invention and that features or portions of the invention, may be adopted without the employment of the invention as an' entirety. I do not wish, therefore, that the invention should be understood as restricted to the precise details, except where such details are specifically recited in the claims; nor do I wish the improvements understood as confined to the specific type of mill hereinbefore described.` Thus, for example, antifrictionballs may be used in continuous series around the cone-post instead of being interspaced, although I regard the latter as the preferred construction. So, also, the rings arranged around the cone-post for preventing the access of the material being ground to the bearing-surfaces is 'a feature of advantage regardless of the peculiar construction of such So, also, while I prefer to use antifriction-balls I regard the use of antifriction-e rolls when properly disposed as the mechanical equivalent thereof, and so in many other respects modifications within the scope of my invention may readily suggest themselves to the skilled mechanic.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
