Patented Aug. 24, 1915.
To all whom it may concern 'Be it known that I, RAY C. Nnwnousu, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Crusher Mantles, of which the following is a specification. v
This invention relates to improvements in the construction of crusher mantles, and more specifically to means for automatically locking the crusher mantles of gyratory crushers or similar devices, to their support ing elements.
An object of the invention is to provide simple and efiective means for automatically looking or securing the mantles of crushers to their supporting heads or elements.
More specifically, the invention relates to the construction ofa tapered mantle for gyratory crushers, with a helical end surface or its equivalent, at its smaller end, this end surface being adapted for coaction with an adjacent element whereby upon relative rotation of the mantle the same is automatically forced onto its supporting member.
Another object of the invention is to provide means for automatically locking or tightening the mantle of a crusher to its forming them of opposite pitch or supporting member during relative rotation of the crusher mantle in either direction, this result being attained in applicants device by compounding inclination relative to a plane perpendicular to the The present invention is applicable either to a unitary mantlein which the mantle is constructed entirely of one piece, or to a sectional mantle in which the mantle is formed of a series or plurality of individual mantles.
A. clear conception of an embodiment of the invention may be had by referring to the drawing accompanying and forming a part of this specification in which like reference characters designate the same parts in the various views.
Figure 1 is a top view of a gyratory crusher head center and mantle, showing the suspension shaft thereof in section. Fig. 2 is a side elevation of the crusher head disclosed in Fig. 1. 'Fig. 3 isa transvem centhe end surfaces and.
tral vertical section through vthe crusher head and mantle disclosed in Figs. 1 and 2.
The crusher head center 2 which may be formed integral with the shaft 1, is secured to the tapered portion of the main crusher shaft 1 by means of a series of keys 3. The
outer surface of the head center 2 is tapered or conical in shape, converging upwardly. The lower and upper mantles 4c 5, respectively, are fitted upon the outer tapered surface of the head center 2 and are formed with inclined or helical surfaces 12, 13, or their equivalents, at their upper ends respectively. In order to facilitate description of the invention, the surfaces 12, 13, will be designated as helical surfaces, but it should be understood that this term is intended to include all forms of. surfaces which will cause the elements coacting along these surfaces to separate or move away from each otherupon relative rotation of one of these elements. The helical surfaces 12 at the upper end of the lower mantle 4 are formed directly on the mantle and coact with correspondingly formed helical surfaces 12 at the lower end of the mantle 5. The helical.
ing means. The surfaces 13 may, however,
be formed directly on the mantle 5 if so desired.
The helical surfaces 13 at the upper and smaller end of the mantle 5 coact with similar surfaces formed on the ring 7. The ring 7 is locked against rotation relative to the main shaft 1 by means of keys or other suitable locking means 10. The ring 7 is prevented from moving upwardly along the shaft by means of a ring nut 8 which coacts with screw threads 9 formed on the shaft 1 and which is adjustable along the shaft 1 by the insertion of a suitable instrument within the recesses or notches 14. The ring nut 8 is normally locked in position by means of the usual lock nut, not shown, which coacts with the upper threads 9 and with the upper surface of the nut 8. The helical surfaces 12, 13, are compounded, some of the surfaces being of opposite pitch from others. As disclosed, the upper end head center taper.
fixed upon the main shaft 1.- The interior surfaces of the mantles 4, 5, are then ground surface of the head center 2. After being properly fitted to the head center 2, and
after having had their upper inclined or helical surfaces 12, 13, fitted to coact with the correspondingly shaped surfaces of the adjacent elements, the mantles 4, 5, are placed over the head center 2. The ring 7 is then slipped over and keyed to the shaft 1 and brought into the position shown in the drawings. The ring nut 8 is screwed down upon the ring 7 and acts through the rings 7, ,6, to force the mantles 4, 5, upon the As it is customary to construct the lower mantle 4 of manganese steel and the upper mantle 5 of chilled cast iron, where sectional mantles are used, the lower mantles 4 tend to stretch and become loose upon the head center taper to a greater degree than does the upper mantle 5. As the lower mantle 4 becomes loose upon the center 2,
' the material being crushed and contacting with the outer surface thereof will tend to rotate this mantle upon the head center 2.
' This rotation of the mantle 4 causes the the surfaces 12 of the 40 helical surfaces at the upper end thereof to slide along the adjacent helical surfaces at the lower end of the upper mantle 5. This relative sliding of the lower mantle upon adjacent element, causes the mantle 4 to move downwardly or away from the mantle 5 and to become automatically looked upon the taper of the head center 2. If the upper mantle 5 becomes stretched it will rotate upon the tapered outer surface of the head center 2, and the helical surfaces 13 at the upper end thereof will slide upon the similarly formed helical surfaces on the under side of the ring 7.
'Thissliding of the helical surfaces 13 of the mantle 5 upon those of the ring 7 will force the mantle 5 downwardlyand away from the locked ring 7, and firmly lock the mantle upon the taper of the head center 2.-
. free to rotate and lock even if the lower mantle 4 has been previously fixed to the center taper.
It will be noted that by forming helical surfaces 12, 13, of opposite pitch or inclination relative to planes perpendicular to the crusher axis, at the upper end of each of the mantles 4, 5, the mantles will automatisally loch upon the taper of the head center 2 upon relative rotation of the mantles in either direction- The formation of these surfaces 12,13, as approximate helices furthermore insures surface contact between the adjacent elements at all times. 7
By locking the mantles 4, 5, to the head center 2 by means at the upper and smaller ends of the respective mantles, the use of interlocking devices between the separate mantles, such as is necessary when the locking of the lower mantle to the headcenter 2 is from its lower larger end, is avoided. The use of helical surfaces at the smaller endsof the mantles, furthermore causes the mantles 4, 5, to move away from their adja-' cent forcing elements during locking. As
of very hard material which is dificult to machine, it will be seen that the use of approximate helical surfaces which may be readily formed by casting, is of great importance in that it eliminates necessity of machining othen than possibly a slight amount of grinding. By forming helical surfaces 12, 13, of suitable contact area, as distinguished from screw threads, a Very strong and serviceable construction is secured.
Although the drawings disclose a crusher head in which a separate head center 2 is employed, it is not intended to limit the invention to such application, as the head center is often formed in one with the A crusher shaft 1, especially in the smaller size machines. The mantles 4, 5, may also be combined to form a single mantle without departing from the scope of the present invention. It should be understood that it is not desired to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
It is claimed and desired to secure by Letters Patent,

said mantle being formed with a surface at its smaller end adapted to coact with an adjacent element to force said mantle away from said element and onto said head center taper during crushing operation.
