JOSEPH L. KILLER, OE MATTAPOISETT, MASSACHUSETTS.
RUSHING OE PULVERIZING MAGHINE.
Specication of Letters Patent.
Patented nee.` o, 191e,
Application filed December 9, 1908. Serial No. 532,262;
T o all whom it may concern;
Be it known that I, JOSEPH L. HILLER, a
. ,citizen of the United States, residing at v lowing is a specification.
This invention relates to improvements in crushing or pnlverizing machines of the revolving hammer type, and has for its object to provide a novel means and arrangement whereby a relatively hardor less friable mav ,4 ration, omitting verse passagef and as hereinafter terial may be separated from the softer or more friable material and separately discharged from the machine.
; In rnn-of-nine coal slate and sulfur balls,
- cand oftenemetallic articles, such as bolts,
spikes, etc., accompany the coal. The presence of such impurities and article s in the crushing machine is undesirable, ,and the presence of such impurities-in the crushed product renders the coal-less valuable. p ,l My invention is designed to provide a machine which will automatically discharge an such objectionable material, and to that en resides in a machine embodying the features hereinafter `described,.sliown in the accompanying drawing, and then pointed out in the claims.
In the accompanying drawing :#Figure l is a longitudinal section. Fig. 2, an end elethe screen shown in Fig. 1.
In said drawing the reference numeral 1 designates the cylinder in which the revolving hammers 2 work. 3' designates the cage or grinding-surface that cooperates with said 4hammers and which is preferably pivoted at ,all as is well known in the art.
In rear of the grinding surface or cage 3, as viewed in respect of the direction of rotationof the hammers 2, the cylinder 1 is provided with a transverse passage 7 through which relatively hard or less friable material,
passes under the iniiuence of centrifugal force. A fender 6, preferably inclined as shown, is provided at one edge of the trans- 7 and4 stands in the path of movement of'the material in the cylinder. This fender 6,. as shown, is supported by a part. 5 of the frame-work of the machine,
described may be adjustpart so that a'passage ably connected to said maintained of predetermined area may be and at the same time adjustment of the cage'` 3 to4 compensate for the wear of the hammers 2 permitted.
The assage ment o the invention, is provided by a space between the end of the cage and the tender, and leads to a slide 8, on which such mate.- rial passes away. In order that any crushed or pulverized material-that may be deflected through the passage 7 together with the eliminated forei Yn matter may be saved and delivered into tie `pit'i) with the mass of crushed matter passing throu h the Ausual openings through the ca e, te slide 8 is preferably a screen movab y supported on a bracket 10 carried by the machine-frame, on, which itmay be reciprocated in any'suitable 7i, in the illustrated emboaiway, as b`y` means of an eccentric pitman 11,v
as shown.
12 designates a deflector arranged to guide the crushed or pulverized material that passes through the screen 8 to the pit 9 beneath the cage 3. A
The fender G may be adjustably supported as by means of a slot and bolt connection 13, and the area of the passa e may be made adjustable by means o. a age 14, shown as a screw'stud adjustably tted in the cross-bar 15 connecting the free ends of the cage-carrying arms 16, and adapted to abut against a bracket'l'( connected to the adjustable fender 6. The. meeting of the gage and the bracket determines the limit of movement of the cage toward the fender, and it is obvious that by manipulating the gage the area of passage 7 may be varied. The described adjustability of the :fender may be availed of to permit the cage to be ad- 'usted to and from. the hammers to compensafe for wear of the latter and still maintain the 'free passage 7 for the discharge of uncrusliable matter as set forth.
When impurities, such as slate and sulfur balls accompany coal to be crushed, and whic are less friable or harder than the coal and therefore are not apt to be crushed .the first time they pass over the grindf surface, such impurities are, as descri y, dischargedthrou h the passage 7- instead of being carried' a out in lthe cylinder and possbly by repeatedaction of the hammers broken u suiiciently, ne to pass through the openin s of the inding'surface with the. crushe coal, which is undesirable and lessens the value of the coal. The machine, therefore, causes a separation between the concerned therewith). Weights 21 are also vcage adj usted to in cylinder in the path of material to be crushed and impurities acl com anying the saine based on the relative i fria ility of such material. While the utility of the machine has been set forth with respect to crushing coal, the invention is not intended to be limited to E such use, but is claimed for all the uses of which it is capable, as it provides a very simple and elicient. means for automatically discharging from the machine objectionable hard or less friable material that may enter I the machine with the material to becrushed. The cage 3 in practice is ordinarily se- I cured to the cage frame 16 by bolts, and after much use mayI have to be renewed. To enable the Worn ca re to be removed and a new one substitute it is desirable to provide that the cage may be lowered sutliciently to enable access to be easily hadfor the removal of the old and the substitution of the new cage. Although the same is not concerned in the present invention, means are provided by which the cage maybe easily lowered and raised again and whereby also the v4cage may be adjusted with nicety to compensate for the Weav of the hammers. This means consists of chains 18-passing over ocket sheaves 19 carriedby a shaft 20, Whicli) shaft may be rotated to take up `or let out the chains, by any suitable means, (which. are not shown as the invention is not connectedto the cage to assist -its downward movement when the chains are paid out by' the oeket sheaves 19. Y
Hiiving thus described the invention, what Iclaim is,-
l. A crushing machine comprising a cylina. portion of which constitutes a grinding surface or cage having openings for the passage of crushed material, said cylinder having a transverse passage opening therefrom 1n rear of the grinding surface or cage,
