Application filed July 23,
T0 aZZ whom it may concern:
Be it known that I, Josnri-r L. HiLLnn, a citizen of the United States, residing at hilattapoisett, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Rotary Heaters for Swing-Hammer Crushers, of which the following is a specification.
This invention relates to method. For the manufacture and use 01. rotary heaters bclonging to that branch of the art in which Patent No. 1,197,026 was granted on Sept. 1916, to me and being adapted for use in the class of machines described therein, in. machines of the rotary beater typo no not possess adequate adjustments to compensate for the wear of the heaters, and in any machine of the rotary beater type which is desired to operate in balance. I i
The object oif'the invention is to secure greater accuracy of rotor balance in a practical cheap way, to prolong the life of the wearing unit, to lessen the discard of ma terial and. to reduce the cost of the wearing parts and so reduce the upkeep of. the ap paratus employing the invention.
In the rotary beater type of crushing machine, by far the greatest cost is for heater renewals. The method disclosed in Patent No. 1,197,026 hereinbefore referred to, is such as to effectuate large savings compared with the prior art, but has no less than four disadvantages as compared with the present invention.
First, from observations, covering the manufacture and use of many thousai'ids of single piece heaters, I find it is impractical to count on a less variation than about one half pound in weight between the lightest and heaviest heaters of a set, and this variation makes it desirable to weigh each batter, every time it is changed and then, by skillful manipulation, to arrange them in balance upon the rotor. Second, considerable time is required to demount and reverse heaters after wear. Third, to remove From the crusher, re-machine the working ends and replace is an expensive operation and at best there are but two wearing edges. Fourth, there is a considerable loss of material in the discard after the last use of the beater.
My method of overcoming these deficiencies and 01 accomplishing the objects of my invention is, first to provide heater shanks which are of a permanent nature and in the manu facture'o't which it is, therefore,
1919. Serial No. 312,747,
reasonable to bestow such care as will produce uniform members which will be in balance when assembled or requiring to be arranged in balance only once, if roughly manufactured. Second, to provide relatively small, securely held, easily adjustable, dctachable and renewablesledge blocks, each provided with a greatly increased number of working edges, and. of such form and size that accuracy and cheapness o'lj' manufacture is facilitated.
Thedrawings illustrate the outstandmg features of the arrangements of the elements entering into my invention. The square plates shown in Figs. 1, 2, 3, 1, 5. 6, 9 and 10 and marked 16 is a preferred form or sledge block. The triangular plate shown in Figs. 7 and 8, and also marked 16, is also very economical of material. Both are sun passingly eflicient.
'Claml'iing' and position, locking means are provided which in the square sledge blocks provide for four edges being utilized before the sledge block isreversed side for side to present'four'fresh edges and in the triangular sledge blocks each side presents three available edges.
These sledge blocks may provide through an eccentric drilling for varying the reach of the heaters.
,Reiierring to the drawings in detail, it will be observed that in Figs. 1 and 2 tuc invention consists of the shank 11 provided with means for mounting in the crusher or pulverizer as it would be pivoted if a bar passed through the hole 12. The shank: 11 is provided with a hole for the clamping bolt 18 with two rivets 14: having heads 15 which heads together with the upset portion 13 of the shank provide a three point hearing for the sledge block 16. The project ing heads 15 by entering indentations 17 lock or key the sledge block 16 and prevent its misplacement. The bolt 18 having head 19 and nut. 20 is provided with a lock washer 21 and of course. may be provided with other or additional locking means. It will be noted that the shank 11 is reversible since the rivets 14 have heads 15 on both sides and since the upset portion 13 is identi cal on both sides.
Fig. 3 illustrates the same square'sledge blocks mounted upon an equally sturdy shank 11 which is similar in all respects to that shown. in Fig. 2 except that it is forged so that the angle oi the face of the sledge block is approximately radial with respect to the center of the hole 12, whereas in Fi 2 the face of the sledge block present quite a different angle.
Fig. at represents a lighter type of beater shank and gives an angle to the face of the sledge block which is a compromise between that shown in Big. 2 and Fig. 3. Fig.4; also shows that shank 11 is reversible.
Figs. 5 and 6 show a heater shank 11 adapted for holding the sledge blocks 16 at an angle as for some uses it may be desirable. The clamping and locking means together. with the reversible feature is essentially the same as has been described, but em loys hardened balls staked in the shanks for locking the sledge blocks.
Figs. '7 and 8 illustrate a still diilcrent form of" beater shank 11, both as regards its control oi. the angle of the face of the sledge block and in providing the upsetportion 13 continuous along the full extent of the width or theshaiik and in line with the greatest work upon the sledge block. in the use of the triangular sledge block, the mechanics of a line and point hearing as is provided along the upset edge 13 and in conjunction with the single point 15 is quite satisfactory. Figs. 9 and 10 show a shank similar to that illustrated in Figs. 7 and 8, but adapted for receiving a square sledge block and provides the continuous line support on the back and near the edge which forms the major portion of the crushing surface.
The sledge blocks 16 are relatively light. The indentations 1"? may be readily forged in the sledge blocks thus producing a rela tively cheap renewable wearing portion for rotary beaters.
What I claim is:
l. A rotary beater'ham'mer consisting of a shank member having an opening in each of its opposite ends extending at an angle to each other and provided at one end on one of its faces with projections surrounding the opening at said end, a head member with an opening therethrough and indentations surrounding said opening, and means for clamping or binding said head to said shank said indentations being adapted to receive said projections.
2. A rotary beater hammer consisting of shank and head member and clamping means said shank member having an opening near one end with surrounding pro ections, said head member having an opening with surrounding indentations adapted to receive said pro ections and said clamping member including a bolt adapted to pass through the said shank and head openings and on which said head can be adjusted so to be located relative to said shank. In testimony whereof I have affixed my signature in the presence of two witnesses.
