Specification of Letters Patent.
Patented Dec. 20, 1921.
Application filed August 2, 1920. Serial No. 400,689.
To all whom it may concern:
Be it known that I, JEROME WARD, a citizen of the United States, residing at Waukegan, in the county of Lake and State of Illinois, have invented certain new and useful improvements in Beaters for G'inders, of which lie following is a specification.
This invention relates more particularly to the b xtQlS or grinding members of centrifugal hiding or pulverizing machines. such as are u ed for grinding or the like. When the ordinary flat heaters are used with these machines, the material which is being ground appears to gather or accumulate at the ends of the heaters where the main grinding occurs and consequently the ends become more or less rapidly worn off.
The objects of this invention are to provide an improved. heater for grinding machines; to provide a heater which will direct the material so that it will be properly distributed in the casing of the mill; to provide a heater which will increase the grinding or pulverizing action; and in general, to provide such an improved device as will he described more fully hereinafter.
In the accompanying drawings showing a preferred form of my device:
Figure 1 is a diagrammatical sectional view of a grinding mill showing the heater in position;
Fig. 2 is an enlarged front view of the heater; 1
Fig. 3 is a sectional view taken on the line 3-43 of Fig. 2; and,
4 is an end view.
As shown in these drawings, 5 represents carried on arms 8 in the 'usual manner. These heaters may be made of any suitable material but are preferably cast inthe shape shown and are secured to the arms by means of rivets 9. These heaters are made thicker a their outer edges 10 than at their inner edges 11 as will be readily seen from Fig. 4. They are also somewhat thicker at the ends 12 than at the middle so that they have somewhat concave faces as will be seen from Fig. 3. The grinding faces are preferably roughened or corrugated as shown at 13 in order to increase the grinding action. They are also provided with one or more diagonally arranged ribs 14:, which tend to force or direct the material from the inlet 6, toward the opposite side of the casing.
From this description it will be seen that not only arethe usual portions of the beatconsiderably thickened, but such thickening and conformation of the plates tends to distribute the material more evenly across the mill so that'all of the grinding parts are worn more evenly. Furthermore the concave faces of the heaters tend to prevent the material from collecting at. the ends or in the corners of the casing. I have found that in actual practice these heaters will last longer than the ordinary flat heaters and will do more efficient work. It will be noted that the form and size of the heaters may be modified for different mills, and therefore I do not wish to be limited to the exact construction herein shown and described except asspecified in the following claims.
i claim 1. i i. heater for grinders, comprising a substantially rectangular plate which is thicker on the outer edge than at the inner edge and thicker at the ends than at the middle, thereby forming a substantially concave grinding face longitudinally of the heater.
2. A beater of the character set forth having a head portion which is thicker at the outer edge than at the inner edge and thicker at the ends than at the middle and is provided with one or more diagonally arranged ribs on the face thereof.
3. Bill improvedbeater comprising a plate which is tapered from the outer edge toends toward the middle and provided with a roughened grinding face substantially as described. 7
'41. heater for grinders, comprising a substantially rectangular cast plate having its grinding faces tapering from the outer edge toward the inner edge and beveled from the ends toward the middle and provided with one or more diagonally arranged de fleeting ribs.
JEROME WARD.
