FASTENING DEVICE FOR SECURING HEADS TO SHAFTS.
SPECIFICATION forming part of Letters Patent No. 548,182, dated October 22, 1895. Application filed February 19, 1895. Serial No. 538,980- oa model.)
T0 at whom it may concern.-
Be it known that I, NATHAN W. Connror, a citizen of the United States, and a resident of Jersey City, Essex county, New Jersey, have invented an Improved Fastening Device for Securing Heads to Shafts, &c., of which the following a specification.
My invention consists of an improved construction of fastening which may in some respects be considered as in the nature of a lock-nut, more especially designed for securing heads upon shafts-as for instance, the conical heads upon the gyratory shafts of ore and stone breakers.
In the accompanying drawings I have shown my invention as applied to the securing of the conical head upon the shaft of a gyratory ore or stone breaker.
Figure l is a perspective view of suflicient of the shaft with its head and the parts of the fastening device detached to illustrate my invention, Fig.2 being a plan view of the shaft and head without the locking and securing rings or nuts; Fig. 3, a plan or face view of the securing-ring; Fig. 4, an inverted plan of the other ring, which may be termed the lockingring, and Fig. 5, a vertical section through the crusher-head and rings on the shaft.
In the gyratory ore and stone crushers as usually constructed the head is secured upon the shaft by means of threaded nuts. It frequently happens in practice that some great strain brought upon the head, tending to push it endwise off the shaft, will cause the threads for the nuts upon the shaft to be stripped 0K and necessitate the supplying of an expensive new shaft. To securely retain heads of this and other character upon their shafts I have devised the fastening which I will now describe.
In the drawings, S represents the shaft of a gyratory ore or stone crusher, and H the conical head fitted upon the tapering part 3 of the shaft, Fig. 5. Immediately above the upper end of this head H I form uponthe shaft a suitable number of lugs A-three in the present instance-the spaces a left between the lugs being preferably about equal to the lugs in width. I provide two nuts or rings D and E, the ring D, which, for convenience of eXplanatiomI will term the securing-ring, is formed on its inner face witha number of lugs or flanges dand intermediate spaces d, corresponding in number and width with the lugs A, and intermediate spaces a, so that when the ring is passed over the upper end of the shaft S the lugs cl on the ring, will pass through the spaces a between the lugs A on the shaft, while, on the other hand, the lugs A will pass through the spaces dibetween the lugs 01 on the ring. By then turning the ring partly around the shaft (one-third of a revolution when there are three lugs) the lugs upon the ring will then take under the lugs upon the shaft, and in a position coinciding therewith, and the spaces d upon the ring will be in line with the spaces a between the lugs A on the shaft. The second ring E, which,for convenience, I will term the locking-ring,is provided with three fingers or projections e of a width equal to the spaces d between the lugs on the securing-ring D and also the spaces a between the lugs A on the shaft. By now slipping this locking-ring E over the shaft S these projections or fingers 6 will enter the spaces d and a, and thus lock the securing-ring D to the shaft, so that it cannot turn independently thereof.
To fasten the locking-ring E to the securin g-ring D, set-screwsf may be provided, passing through the ring E into threaded openings in the ring D.
On the adjoining faces of the two rings D and E there may be provided radial interlooking or other suitable tongues and grooves f and f In order to get a proper bearing upon the end of the head H, I pass through threaded openings in the securing-ring D set-screws h, and to preventlthese from working loose after they have been screwed up I provide poly onal openings 6 in the locking-ring E to fit over the correspondingly-shaped heads of the set-screws.
I claim as my inventionl. The herein described-fastening for se curing heads &c. upon shafts, and comprising a shaft provided with spaced lugs, a securing ring having internal spaced lugs to pass between and engage with those upon the shaft, and a locking ring to. prevent the securing ring from turning, substantially as set forth.
2. The herein described fastening for securing heads &c. upon shafts, and comprising a shaft having spaced lugs with a securing ring having corresponding internal lugs adapted to pass between and engage with those upon the shaft, and a locking ring havin g fingers or projections parallel with its axis to enter between the lugs on both the securing ring and shaft to prevent the securing ring from turning, substantially as set forth.
3. The herein described fastening for securing heads &c. upon shafts, and comprising a shaft having spaced'lugs, a securing ring having similar spaced lugs to pass between and engage with those on the shaft, set screws on the said ring to bear upon the head, and a locking ring provided with projections to enter between the lugs on the securing ring and shaft and having also openings to engage with the heads of the set screws to prevent them from working loose.
4. The herein described fastening for securing heads, be. upon shafts, and comprisin g a shaft having spaced lugs, a securing ring having internal spaced lugs to pass between and engage with those upon the shaft, and a locking ring to prevent the securing ring from turning, the two rings having interlocking tongues andgrooves.
5. The herein described fastening for securing heads &c. upon shafts, and comprising a shaft provided with spaced. lugs, a securing ring having internal spaced lugs to pass between and engage with those upon the shaft, a locking ring to prevent the securing ring from turning, and means for fastening the locking ring to the securing ring.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
