ARRANGEMENT FOR SECURING OF THE BOWL LINER OF CONE CRUSHERS Filed April 26, 1955 X1623, aw, fmz/ b IZZaPILe y-S- Patented Aug. 17, 1937 UNITED STATES PATENT OFFICE- ARRANGEMENT FOR SECURING OF THE BOWL LINER OF CONE CRUSHERS Application April 26, 1935, Serial No. 18,447 In Norway March 6, 1935 2 Claims.
The present invention relates to the securing of the bowl liners of cone crushers and has for its object to provide a securing arrangement enabling a quick and easy replacing of the liner,
the securing elements at the same time being well protected against wear from the material to be crushed. This is according to the invention obtained thereby, that the liner is provided with a collar, in the outer side of which, facing from the crushing surface, a ring-shaped groove is cut, with which ring segments provided with conical surfaces are brought into engagement. The ring segments secure the liner to the bowl, the conical surfaces of the segments pressing the 5 liner against thebowl when the screws connecting the segments together are tightened. The location of the liner relatively to the bowl may be adjusted by means of flat washers or shims between the surfaces of the segments and the adjacent surface of the bowl or mantle.
An embodiment of the invention is illustrated in the accompanying drawing, in which Fig. 1 shows a vertical section through the top of the liner with its collar and with the securing segments. Fig. 2 is a plan view of the segments, Fig.
3 a vertical section through one of the segments on the line A-B in Fig. 2 and Fig. 4 a side view of a segment.
I is the conical bowl liner provided with a reduced portion or neck 2, in the outer side of which an annular groove 3 is cut with a conical annular surface 4 at its top. The ring segments 5, the annular upmost surfaces 6 of which are conical and which correspond to the conical surface 4 of the annular groove in the collar, can
provided between the ring segments and the bowl I. By tightening of screws inserted in the lugs v9 at the ends of the various ring segments for connection of the same, the upper conical surfaces of the segments will bear against the conical surface in the groove of the collar and press the liner against the bowl respectively against material cast between bowl and liner. moval of the liner, the screws are loosened and the individual segments wedged apart whereby the pressure between liner and bowl is released.
It is obvious from the embodiment described that the securing elements are not subjected to wear from the material to be crushed and that For rethe replacing of the liner can be undertaken quickly and easily. The securing arrangement enables an even distribution of the material in the bowl and renders a. simple and cheap construction of the liner possible.
The invention is not limited to any specific number of ring segments, but any number of such segments may be used. Further, the conical surfaces can be provided on the lower sides of the ring segments, bearing against a corresponding annular conical surface on the bowl, whereby the same effect is obtained. Also, both the upper and the lower sides of the segments may be conical and bear against conical surfaces in the liner as well as on the bowl.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. In a crusher, in combination, an outer or supporting bowl of generally conical shape and open at its smaller end, a liner within the bowl and having a reduced neck or collar at its smaller end which projects beyond the end of the bowl, the said bowl and liner neck having annular mutually facing surfaces which diverge outwardly at a uniform angle about the circumference, and an annular ring encircling said liner neck and having relatively inclined oppositely facing surfaces which engage, respectively, the mutually facing surfaces of the bowl and liner, said ring comprising a plurality of segments, said segments being relatively long and narrow, and threaded elements connecting adjacent ends of the segments and by means of which the ring may be circumferentially expanded or contracted.
In a crusher, in combination, an outer or supporting bowl of generally conical shape and open at its smaller end, a liner within the bowl and having a reduced neck or collar at its smaller end which projects beyond the end of the bowl, the said bowl and liner neck having annular mutually facing surfaces which diverge outwardly uniformly around the circumference, and an annular ring encircling said liner neck and having relatively inclined oppositely facing surfaces which engage, respectively, the mutually facing surfaces of the bowl and liner, said ring comprising a plurality of elongated sections and means to circumferentially contract said sections to wedge the bowl and liner in opposite directions and to thereby seat the liner firmly in the bowl.
