GRINDING-MILL.
SPECIFICATION forming part of Letters Patent No. 790,619, dated May 23, 1905.
Application filed October 22,1904. Serial n0. 229,592.
To all whom, it mag concern:
duce a device of this character simple in construction, inexpensive to manufacture, eificient and rapid in action, and adapted for the reduction of any of the various forms of feeding products or materials.
With these and other objects in view,whicl 'v will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.
In the accompanying drawings, forming a part of this specification, and in which cor responding parts are denoted by like designating characters, is illustrated the preferred 'form of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without de-- parting from the principle of the invention or sacrificing any of its advantages.
1n the drawings thus employed, Figure 1 is a side elevation with one side of the supporting-frame removed. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a plan view in section on the line 3 3 of Fig. 2. Fig. 4 represents a modified form of the construction. fied form of construction. Fig. 6 is'aview similar to Fig. 2, representing another modified form of construction in section on the line 6 6 of Fig. 7. Fig. 7 is a section on the line 7 7 of Fig. 6 with the movable member detached. Fig. 8 is a view of one of the stationary plates detached, illustrating a modification in the arrangement of the grindingfurrows. Figs. 9, 10, and 11 are other modified forms of the construction.
In the improved device is comprised gener- Fig. 5 represents another modially a stationary member having one end straight and the other end curved outwardly and a member having grinding-furrows and mounted for movement parallel to the straight portion of the stationary member.
In the improved device is also comprised approved means for constructing, mounting, and operating the different members and adjusting the same, and to this end the improved provided with spaced grinding-furrows 2526,
respectively, in their adjacent faces. Pivoted by their inner ends to the members 23 24, near their lower straight portions, are threaded rods 27 28 29 30, passing slidably through unthreaded apertures in the cars 19 2021 22 and provided eXteriorly of the ears with nuts 31, 3'2, 33,- and 34. By this means the free ends of the members 23 24 may be adjusted laterally and prevented from inward movement, While at the same time free' to move outwardly, as will be obvious.
Attached to the side members 11 are yokeframes 36, having central threaded apertures in which adjusting screw-rods 37 38 operate, the screws provided with nuts 39 40. Springs 41 42 surround the screw-rods for bearing by their ends, respectively, against the members 23 24 and the nuts 39 to yieldably support the lower ends of the swinging members 23 24 in position, as hereinafter explained. Disposed for vertical movement between the members 23 24 is an intermediate member 43, having ribs 44 45 upon its ends for engaging the channels 17 18 in the side members 10 11 and also provided with spaced grinding-furrows 46 47 in its opposite faces.
Attached transversely of the base members 13 14 is a bar 48, adjustable upon the base members, as by bolts 49 50 passing through apertures 5152 in the same. Depending from the bar 48 is a hanger 53, in which an operating-lever 54 is pivoted at 55, the lever being likewise connected, as by links 56, to the intermediate member 43. The operating power will be applied to the lever, as by a rod 57, leading from any source of power, such as a windmill or the like.
The lever 54 is provided with a plurality of spaced apertures to enable the lever to be adjusted to any required extent to change the leverage, and thus adapt the device to different kinds or conditions of the feed material to be reduced. A feed-hopper 58 is supplied to receive the material and guide it intothe spaces between the curved members 23 24 and the intermediate member 43. By this arrangement it will be obvious that when thus assembled and the intermediate member rapidly reciprocated the material will be gradually reduced and finally discharged at the lower side in finely-divided particles, the fineness being determined by the adjustment controlled,
by the nuts 31, 32, 33, and 34, as before stated.
The outwardly and upwardly curving form of the members 23 24 is an important feature of the invention, as the grinding-surfaces are thereby very materially increased and all tendency to clogging obviated, no matter how large the supply of material may be, the coarser particles being first acted upon within the larger area nearer the hopper and partially reduced and then reduced to a finer and still finer extent as they approach the final point of discharge, where the members 23 24 and theintermediate member are formed with substantially parallel surfaces. The action is thus very rapid and thorough, as the grinding effects are produced during both the upward and downward strokes of the intermediate member, especially in the lower portion, Where the finer reducing takes place.
The device may be constructed for fine or coarse grinding, as may be required, as the dress of the grinding-surfaces may be of any degree of fineness. The novel form of the members 23 24 thus very materiallyincreases the rapidity of the action and correspondingly increases the quantity of the product within a certain predetermined time. The rapidity and thoroughness of the reduction is thus materially increased without increase in the expense of construction or the power required to operate the mill.
The device may be constructed in any desired size, and any required power may be employed to operate it, but is more particularly adapted for operation by windmill-power.
In Fig. 4 a modified form of the device is shown wherein furrowed rollers 60 61 are inserted in the members 23 24 for coaction with the intermediate member 43, and in Fig. 5 another modified form of the device is shown, with the intermediate member43 replaced by afurrowed disk 62, mounted for rotation upon a shaft 63 and operating through aslot in the side member and between the members 23 24, which may be employed when a continuous motion in one direction is desiredas, forinstance, when power other than a windmill is employed. Any suitable means may be employed for operating the shaft 63. Theroller members may be located at or near the lower ends of the curved portions of the members 23 24, as in Figs. 6, 7, and 10. or at or near the upper end of the curved members, as in Fig. 9, and the rollers may be furrowed, as in Figs. 4, 6, 7, and 9, or smooth or without furrows, as in Fig. 10, according to the work required or the condition or quality of the material to be reduced. The members 23 24 may also be without the grinding-furrows, as in Fig. 4, for reducing some kinds of material. The roller may also be arranged for adjustment at one end, as in Figs. 6 and 7, by means of a screw-rod 64, operating from a sleeve 65 on the shaft 66 of the roller, and controlled by nuts 67 68, bearing upon brackets 69 70 on the casing, as shown in Figs. 7 and 11, so that the furrows of the roller may be caused to operate at an angle to the furrows on the member 43 or 62, as will be obvious. By this arrangement both a crushing and cutting or shearing action is obtained, which is very efiicient in reducing certain kinds of material. The furrows in the members 23 24 or in the movable member 43 may also be disposed at an angle to the horizontal plane, as indicated in Fig. 8, if required; but none of these modifications will be a departure from the principle of the invention, as they all produce substantially the same results.
