JAMES F. XV INCHELL, OF SPRINGFIELD, OIlIO,ASSIGNOR TO THE FOOS MANUFACTURING COMPANY, OF SAME PLACE.

FEED-REGULATQR FOR GRlNDlNG-MILLS.

SPECIFICATION forming part of Letters Patent No. 396,058, dated January 8, 1889.

Application filed April 23, 1887. $erial No. 235.849. (No model.)

To all whom it may concern.-

Be it known that I, JAMES F. VINCHELL, a citizen of the United States, residing at Sprin gfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Feed-Regulators for Grinding Mills, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in crushing and grinding mills, and is designed to reduce corn-cobs, (with and without the grain upon them,) bark, bones, roots, and other substances first to a broken or coarse state and then to such finer state as may be desired; and it consists in combining an adjustable feedregulator with a crushing-chamber, whereby the rapidity of the passage of the material from said chamber to the grinding mechanism proper may be controlled to suit the different kinds of material and the different conditions which may arise from time to time in the practical use of the machine.

The mill generally is by preference of the general character shown and described in Letters Patent granted to me May 18, 1886, and numbered $2,158, for crushing and grinding mills.

In the accompanying drawings, forming a part of this specification, and 011 which like reference-letters indicate corresponding features, Figure 1 represents a vertical sectional view of a mill of the character just alluded to, showing my improved feed-regulator in sections; Fig. 2, a transverse vertical sectional View through the hopper, the crushing-chamber, and the crusher, showing the feed-regulator in elevation; Fig. 3, a plan view of a portion of the main casing, showing the crushing-chamber and the feed-regulatortherein and its different positions; Fig. 4, an inverted plan View of that portion of the casing shown in Fig. 3, and also showing the means of adjusting the feed-regulator.

The construction and arrangement of the frame, the casing, the main shaft, and the grinding heads and plates, as also the adj usting mechanism for the shaft, are the same in the present case as in my Letters Patent above alluded to. These features, however, may be varied at pleasure and some other form of frame and mechanism adopted. Therefore a minute description of the machine generally, exclusive of the feed-regulator and the crusher, is superfluous in this place. Furthermore, the machine generally is used interchangeably with the devices peculiar to crushing comparatively large substances, the devices peculiar to grinding cereals, and the devices peculiar to hulling seed.

Referring now to the peculiar features involved in the present case, the letter A designates the crushing-chamber, through which the material passes from the hopper on its way to the grinding mechanism proper, and

the letter B a series of bars, of which there are three in the present instance. These bars are fitted, as seen more clearly in Fig. 2, across the bottom of the chamber A, the said bottom being flatter in this case, for the purpose of properly acting in conjunction with the bars, than in the patent already alluded to. Formed in the bottom of the chamber are a series of holes, and in each hole is fitted the shank or spindle O of the respective bars, the lower ends of which are preferably angular, as seen at D in Fig. 2, to receive an adj Listing-handle, E, and arms F, and are screw-threaded to receive nuts G. The arms F are connected with the handle E by a pitman, H, through pivotal jointsv Secured to the casing or forming a part of the general structure of the mill is a notched bar, I, with which the handle E is adapted to engage for the purpose of locking the same in any set position. It will now be observed that upon actuating the handle E more or less in one direction or the other the bars B will be adjusted at varying angles across the crushing-chamber, and also that their general direction will be changed, as suggested by the full and the dotted lines in Fig. Now let itbe supposed that the crusher (to which reference will hereinafter be made) be revolved in the direction indicated by the arrow in Fig. 2, which is the direction indicated by the arrow in Fig. 3, and the bars B areiaw e shown in the full lines in Fig. 3. will be very much less rapid in the position shown in the dotted lines iii said .tigure. This is one illustration of an eittreme dil'ferenee which. may be effected in the speed of the feed of the mill. It will be understood, however, that a variation in the angle of the bars ll across the chamber, yet without ehz'lngi ng their general direction, will also change the speed of the feeifl. Thus my improved feed-regulat or will control the slow to feed from maximum. to minimum degree and the fast feed from maximum to minimum degree.

I have described what I consider to be the best means of carrying out my invention; but

I wish to be distinctly understood as not in any sense eonlining myself to this form of construction, since my invention is, broadly, that of regulating the feed by a regulator located in the erushing-chamber and capable 2o oi varying the speed of the feed.

The letter 1' refers to the crusher, the same being mounted on the main shaft of the mill, and secured either in the manner set out in the patent already alluded to or in any other way, and [)lUYltlttl with crushing lugs or protuberances ii. These lugs I have shown with sides substantially parallel to the axis of the crusher, as being a form highlyuseful in combination with my feed-regulator. The shape of these lugs, however, may be varied, and may be changed to the shape of the lugs shown in said patent. l have spoken of the crusher as a crusher, and of the chamber A as a erushing-ehaml)er, and. have used these terms for the sake of harmony with the terms used in my said patent and others re cited in it which have been granted to me; but it is not to be understood that if the crusher acted merely as a ti'onveyer and 40 the chamber as a eonveying-chamber a departure from my invention would therebybe brought about. As a matter of fact, the organization here shown and (hescribed accomplishes both the crushing and the conveying 4.5 .Ifunetions, and. the bars 13 assist in the crushing operation while ('zontrolling the speed of the feed operation. It will be further noticed that when the bars are in any given positimii they \irtually become fixed, as distinguished from the adjustable, sothat ba rs permanently fixed to the chamberwould be but their equ i v alent without the changes of adjustability. The plate 1h may or may not be used, and forms the same function as the plate K. in my Letters Patent already reoitedto wit, that of lttllltjlllfl, the size of the clntmber, so as to crush. eobs or substances much smaller than the average cob.

Having thus fully desm-ibed my invention, what I claim as new, and desire to secure by Lott: rs Patent, is

1. In a mill, the combination, with a casing and a erushirig-chamber composing a part of the frame thereof, a main. shaft rotated longitudinall y through the chamber and across the casing, and grinding mechanism in the casin near one end of the chamber, the rotatin part thereof being carried by said shaft, of a series of bars located across the chamber, having shanks which extend through the wall of the chamber, a handle on one of them and arms on the others, a bar connecting the arms with the handle, and a locking device with which the handle engages, whereby the said bars may be adjusted and. held, and a cylindrical body on the shaft having lugs or projections which eoact with said. bars and crush the material and feed it to the grinding mech anism.

2. In a mill, the combination, with a casing and a crusiting-chamber composing a part of the frame thereof, a main shaftrunning longitudinally through the chamber and across the casing, and grinding mechanism in the cas ing near one end of the chamber, the rotating part thereof being Gitl'liOtl. by the said shaft, of a series of bars located across the said chamber,having sh :tnhs W] l ieh on ten d th rough the wall thereof, devices connected to said shanks to adjust and. hold the bars at ys'urying angles in one gmieral direction and at varying angles in the opposite general directitm,whcreby said bars control the speed of feeding from the maximum to the minimum degree of slowness and from the maximum to the minimum degree of rapidity, one of said directions being of a general slow feeding and the other of a general. faster feed, and a cylindrical body on said shaft within said chamber, and having j)eripheral lugs or projections which coact with said bars to crush and feed the material.

In testi mony whereof I attix my signature in presence of two \vitnes JAMES l. \\'l N t H Elli).
