Specification of Letters Patent.
Patented Aug. 11, 1908.
Application filed September 28, 1906. Serial No. 336,609.
To all whom it may concern:
Be it known that we, 'lnsEPiI L. and GEORGE W. Boirrox, l'nited States, residing,
lilLLElt (lllltllS of the respectively, in
Mattapoisett, .\lassacl iusetts, and lladdon field, New Jersey, have invented certain improvements in l'la]niner-(rushcrs, of which the following is a specification.
()ur invention relates to an improved form of machine in which granular or lump material is pulverized by rotary hammers; one object of the invention being to provide a device of this class whi h shall be of relatively simple c nstruction and shall require for its operation the expenditure of less work than has hitherto been the case.
We further desire to provide a device for crushing lump material in which, after said material has been engaged by the rotating hammers, it shall be forcibly thrown by the hammers so as to move along lines tangential to the hammer circle into engagement with'a crusher plate or plates on which furthcr crushing or breaking occurs.
Another object is to provide means whereby the position of the crusher plate may be adjusted redatively to the hammers.
'Ihese and other advantageous ends we secure as hereinafter set forth, reference being had to the accompanying drawings, in which:-
Figure l, is a vertical section of a hammer crusher constructed according to our invention; Fig. 2, is a side elevation of a machine somewhat similar to that shown in Fig. l, but provided with a different form of crusher plate. Fig. 3, is an end elevation of the machine shown in Pig. 2; Figs. 4 and 5, are per spective views illustrating the detail conof crusher plate used respectively in the machines shown in Figs. 1 and 2, and Figs ti and 7, are views of modified forms of crusher plates.
.ln the above drawings, A represents the a hammer crusher upon which is supported a casing A of generally cylindrical form, provided with a part (I which may he perforated, if desired. A hopper portion a isprovided for material to be crushed andonc side of this hopper is provided with a breaker plate a.
I re perforated portion a of the casing is supported upon a. movable frame to ,the main frame at b and supported-at its opposite end by chains 1) passing over suitthe reception of B pivoted able holding pulleys f)" on the shaft 1). This shaft may he turned to raise or lower the l frame B and consequently the perforated plate a by means of a gear wheel 1' meshing with a pinion I). This pinion may he turned at will by means of a hand wheel If carried on a shaft b common both to said wheel and said pinion.
The main shaft C of the machine is carried I in suitable bearings c and c on the frame 1 I and has a driving pulley cflas shown in Fig.2.
VVi'thin the casing A, which, it will be noted is substantially concentric with the shaft C, are a number of parallel plates or disks 0, keyed or otherwise fixed to the said shaft; these having pivoted between them a series of hammers 0 there beingany desired number of hammers in each series. The lower quarter of the casing A farthest from the hopper a is omitted and across the opening so formed a. shaft 6 extends. To this shaft is hung the end of the frame B, and, as shown in dotted lines in Fig. l, the chains 1) are attached to said shaft by a suitable l clam A crusher plate 1) is either pivoted or ot ierwise fixed to the shaft b, as desired, and in the case illustrated in Fig. 1, it extends across the open part of the casing both below and above said shaft 11 so that it is below a line tangent to the end of the part a of the casing.
When, under operating conditions, the shaft C, with its hammcrs'and plates, is turned at a high velocity and lump or granular material is fed into the hopper, it will be seen that said material is broken and to some extent crushed by the action of the hammers a, part of it passing through the perforations in the plate a of the casing. The greater part of it, however, is driven or thrown tangentially outward by the hammers so as to be caused to strike violently against the crusher plate B, both above and below the shaft 1). As a consequence, it is further crushed; being, in fact, very completely pulverized and, therefore, falling vertically downward into suitable bins or other receptacles.
If desired, the crusher plates may be corrugated or otherwise roughened in any ,desired manner, indicated at d", in that form of our iiivention illustrated in Fig. 5, or may be made in the form of perforated plates or grates as shown at D and 1), Figs. 6 and 7.
The form of erush'erplate D, shown 'in Figs. 2, 3 and 5, contemplates the use of a shaft b extending transversely across the casing A at a point lower than in the ease illustrated in Fig. 1 and passing through two lugs (1 net on the rear face of said plate. In addition, there are two lugs d" on the upper part of the back of the crusher plate and to these are pivoted links 7) whereby said plate D may be moved toward or from the casing of the machine on theshaft b" as an axis. A clamping screw 1) having a suitable nut is carried on the frame whereby the adjustable links 11 may be held in any desired position.
In the case illustrated in Fig. 1, it will be noted that the frame B may be raised or lowered by means of the hand wheel I) so as to change the position of the crusher plate D relatively to the hammers, while in the form shown in Figs 2 and 3, the angle of the crusher plate, as well as its distance from the hammers, may be varied at will by means of the links I).
As shown in Fig. 3, we preferably inclose the crusher plate entirely within the casing of the machine, though, in order that access may be had to said plate, we provide the lower rear portion of the housing or casing with a door of, keeping it closed by means of a suitable clamp a".
We claim as our invention:
1. A pulverizer including rotary hammers, a casing having an'opcning placed to permit material operated on by said hammers to move in line substantially tangential to the path of movement of said hammers, an adjustable screen-supporting structuri-x, a screen carried thereby, and a crusher plate supported on said adjustable structure in position to intercept material moving in said tangential lines.
2. A pulverizer including. a substantially cylindrical casing having an opening for the introduction of material, and a second opening to ermit of the passage of said material from t e casing, a frame having a screen, a crusher plate supported in said latter opening of the casing, means for holding said plate in position while permitting it to be ad. justable at will, and roty hammers within the casing, the surface of the crusher plate lying in a plane substantially at right angles to a line tangent to the line of movement of the hammers.
/ .3. A pulverizer including a substantially cylindrical casing havin introduction of material to be operated on, and a second opening to permit of the passage of material from the casing, rotary hammers within the casing, a crusher plate supan opening for the ported in the second opening in the casing so that its surface lies substantially at right angles to a line tangent to the line of move- 'ment of said hammers, with means for adj usting the position of said plate.
4. In a pulverizer, the combination ofa casing having within it a main shaft with a series of rotary hammers thereon, there be ing a relatively large discharge opening in the casing having a screen extending across a portion thereof, a shaft parallel to the hammer shaft and mounted adjacent to said opening in the casing, with a crusher plate supported on said shaft in a position to intercept material thrown by the hammers through the opening in the casing.
5. A pulverizer including a series 'of rotary hamincrs, acasing having an opening placed to permit of material operated on by said hammers moving in lines substantially tangential to the hammer path, and. a crusher plate supported adjacent to said opening so as to intercept material moving in such tangential lines, said crusher plate having a roughened surface'and being adjustable towards and from the hammers, substantially as described.
(3. The combination in a pulverizer of a casing having within it a series of rotary hammers and provided with a screen, there being an opening in the casing adjacent to said screen, and a substantially flat crusher plate having means whereby it is supported in the opening in the casing with its surface in a plane substantially at right angles to .a
line tangent to the line of movement of the hammers.
7. 'llie combination in a 'pulverizer, of a casing, a shaft carrying a series of rotary hammers, said casing including a frame adjustable t-ward and from the hammers, a perforated sheet forming part of the casing and carried upon said frame, a shaft on the frame, a crusher plate sup )orted on said shaft so as to extend both above and below the same, and means for rigidly connecting said plate to the shaft, there being an opening in the casing tOPOXIllllZ of material being delivered from .the hammers against the crusher plate.
In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
