Safety Attachment fer Mine Cages.

| C. DOuglas DTONH, ol iTescOLJ, ArlZOna,
 has just patented, through the Mining and
 Scientific Patent Agency, an improvement
 in attachments for mining and other elevator
 cages, by which such cages are prevented
 from falling If the rope or anything else breaks. One of these attachments Is now
 being made by Reynolds & Rix, 49 Ere
 mont St., general agents for the Pacific
 coast, which will be placed on exhibition ill
 working order at the Mechanics fair. Mir Browns device consists in the en- ployment of inclined arms having their outer | ends formed to engage and hold Tn the guide timhers between which the cage moves, while thelr inner ends are connected with ring
 secured to a vertically sliding spindle or king
 bolt having elliptic, spiral, or other springs
 to draw 1t down forcibly ii the rope breaks,
 and thus cause the ends of the inclined arms to engage the guide -timbers As soon as these arms becOme engaged and fixed m the
 guides, the whole weight of the cage Is trans
 ferred to the king bolts, by which 1t Is sus-
 pended, and through 1t direct power Is ex- erted to fix the arms in the guides independ- ent of the spring. 4 sliding ring or sleeve upon the king bolt below the attachment
 of the inclined arm Is connected with them
 by stays or braclng arms, which cause both
 ot the arms to oe thrown out simultaneously '
 and equally prevents them from being
 thrown out too far by the shock, and assist
 III strengthening and bgacirg them.
 The frame of the cage has clips which cx-
 tend upon each si,'e .of the gulde-timbers,
 where the salety-auns will engage them and
 thus prevent the tlmbers from being split by
 the arms when they are furccd into the tim
 bers. Rubber buffers or springs below the

 on springs to relieve the force of the blow.

 ployed for hosting purposes m mining shafts
 From these upper cruss-tmbers an anyu- lar frame extends upward. being bolted or otherwise fixed to the cage frame. and it serves to support d protecting roof, which protects the occupants of a cage from falling rubbish or broken cable.
 Through or between the cross-timbeT., and tE.9Ygh the roof oi the cage, king belt or spindle passes, having vertical or end play, and being prevented from turnin0 around by feathers fixed to it and moving in suitable slots Or guides. To this king-boIt or spindle Is hyed sleeve, having pro- Jectlons at its opposite sides, to which the inner ends of tie two safety arms or dog. ! are pinned. These two arms extend at an | incline downward and outward through 1 slots Tn the frame, so that their outer ends 1 stand in line with the inner faces of the ruIde-timbers (not shown), between which J0 formed that they will readily engage wlth IL, !. 4 - ! ;ard, and they will thus hold the cage SUD- ported fpoIa its spindle.
 Bei@w the tim bers of the cage are secured brings, any kind. Tie spindle passes trough or between the springs, and strong late with adjusting and holding nuts at the Ottom retains 1t iH place, and also enables he inventor to regulate the tension uf til., brings. A plate or head at the top of tho Dindle will serve as stop when the spindle
 drawn down by the spring, and an elastic utfer on the spindle relieves the jar when ,e cage Is suddenly stopped.
 4 loose or .lidin. sleeve IS fitted to slide pon feather on tho spindle being ih. Ned sleeve, and twU arms extend from lu9s . ths sleeve to a point about midway m .e length of the arms. These short arms, ,th theIr sliding sleeve, act togetherto hold e other ains, so that they will be thrown ltward simultaneously, s..d w;ll each en- ge it's guide equally with the other, thus eventing any side strain
 Upon the sides of the cage, it top and V itolg, gre secured clips, which extend out IL lrd upon each 4id2 9f the guide timbers. u d thus insure the central l.6.itiDp of the st ge III the shaft The upper clips are T lced upon each side of the slots in the cage Ia Ime, through which the arms are projected S To the guides, and as they project on each ei le 'f the gu.d,y. they will prevent the lat " " from being split and sp.sal alart by the 1T, ID ton of the dogs. T The floor of the cage has rails, upon which ti IS may be run to be elevated in the usual inner. The spaces at each side of and be- LII LII zen the rails may be fitted with false S' tt"In, winch lests upon springs, so that io , shock of sudden stoPPases of the cage | not be communicated so severely to the he upants of the cage.-(S.
