ELEVATOR.

rosiers.

lle it known thatI l, ALLEN lln.\.\"riNo uur, a citizen ot'. the United States` residing at- Toledo, Lucas county, )hio7 have in vented a new and useful Elevator, ot' which the following is aspeeitication.

This invention relates to disconnecting and stopping,r devices.

This invention has utility when embodied in. elevators, especially of the endless type.

.Referring to the drawings: Figure l is a side elevation with parts broken away of an embodiment of the invention adapted to a` passenger belt. elevator, showin" position or thc iiight in normal travel; big. Q is a view looking from the left toward t-heshow ing' in Fig. l; Fig. 3 a 'fragmentary detail of some of the elements 'forming the brake actuating connections looking trom the lefty toward Fig. and Figi. -l a side view o.t` the invention similar to Fig'. 't with the frame structure eliminated. showing tbc abnormal or stop actuated position thereof.

',lhe driver or belt l normally passes over the pulley 2 'last to the shat't il, which shaft l has fixed thereon the worm -l in engagement with the worm wheel 5 mounted in the casing 6. The worm wheel is fixed to shaftl T to which shaft is also tixed the pul- Vley S over which passes the elevator bclt S).

This elevator belt J has hinged thereon passenger' carrying flights 10 of right angle .t'orn'i which swing; against the vertical reaches of the belt to provide platt'orms upon which Imsscngers may stand. Handholdsl 11. are provided on the belt J in con venient position for passengers riding' np or down on the shelves or [lights l0. Near the outer ends of each of the portions of the llig'hts l0 are extensions 1Q coacting` with the guides 13 on each side ot' the belt t) which preventI the shelf portion ot' the llights l() 'from inclining downward from the hinge 4should the belt 9 become a little slack.

.l passenger aboard the flight 10 to the right ot' Fig. 1, should step ott' on the top floor 14. thus removing` the load from the flight 1t). As the continuously traveling` belt causes the flight; to move upward, the angle lever l5 normally actuated by the sp1-hre 1G is a vieldable guide -device otl sufficient power to contact the flight extension l2 and guide it upward over the trigger elemeiitz- 17 to permit of the regular belt running. This trigger l? has a pin 18. 'lhe trigger' .t7 is pivotally mounted and Specification of Letters Patent.

movable under the nitide 1t), which guide lt) has a slot f2() in which the pin 18 is movable.

' This slot Qt). at its upper end, tern'iinates in an anguh'ir portion deflected away `from the belt t) so that at this portion. the pin 18 will cause the trigger 11T to be retracted ont. ol the line of travel o't `the extension 12..

'lhetrieger element la7 is pirated aty its lower portion upon rack carrying 'frame 22. This 'frame Q2 is 'in mesh 4with pinion 23 upon shat't 24k. This shaft,- Q-l carries a sec ond pinion Q5 in mesh with the gear segment. Q6 mounted upon sha't't Q7 },iarallel to the shaftI 2t. These

shafts

24 and 27 are monnt-4 co in the framework between the, guides t3. 'lhc segment QG has-a weight'I carrying arm lllounted on the shaft: 2? outside the rguides 13 is an arm Qt? to. which, may be adjustably connected thc link il() extending to arm 31 forming with tia-dial portion 32 and the second arm 3? a bell crank lever. (.onnected to the arm 'lll ot the heli crank lever is link 3l extending to the lever 35 pivotally carried by framework 8G. rThis framewm'k 3G together with the elevator' framework proper provides immntinsmr for the shat't` 3, while. the shaft T is mounted di. rcctly in the elevator 'trame struct/ure.. This lever 353 is connected to thc longitudinally slidablc bar 23T on the beltshii'ter which has the belt engaging lingers ltl to more the belt l l'rom the fast pulley on to the loose pulley 39. which loose pulley is carried by the shaft 3.

ltastr to the shat't 2t outside the guides 't3 is the arm l0 having the cross extension 4.1. Astride this element; 40 and loosely mount ed on the shat't fl-'t is the weighted element, l2 having connected thereto the link fill extending to the set screw held sleeve 44 on the longitudinally reciprocable rod 4:3. This rod t5 is mounted in the guides l-(S, 'l'. Adjustably connected to-.the rod Mt5 is'the, sleeve 48 to which is attached link lf) extending to the angle lever 50. The angle lever 5t) is connected to the 'lrnrtion brake strap Cil 'which has its opposite end firmly held by the bracket 52. The rack frame 22 .is slitv ably mounted in the elevator structure and has` tho upward extension to which is connected the manually actnable stop line 54 passing; over the guide wheel. The line extends down beside. the elevator belt St so that by polling the lino or cord .riet the stop device mayv bo actuated from any floor vot the lnrlding. The weight 28 normally holds the n'ieehanisn'i in .-ghitited position ot driving or not. driving'. To reset the stop device. the line 56 may he manually aetuated. which line 5G is eonneeted to the extension if), and extends down alongside the line 5t. The brake 51 when Set. is pulled hy the anA gle lever 50 in the direction o't travel of the brake wheel. ith which the hraltey 3l eoaets,y to .fstopithe shaft after the belt L is thrown on tothe loose pulley 39. Thia sequence ot' operation is preserved owing to the tart that the brake Conner-tionv are aetnated through the weight l2 whie-h is noty thrown until the Shaft-it has made a' rotation to eause the cross portion tl thawing around the Shaft' and knoek the weight away from the rest 58.

Operation: In the normal running of the elevator, passengers riding up will dismount on the top floor 14 thus leaving the flight. l0 unloaded so that spring; it is strongY enough to torre angle `lever l5 outward to guide the extension l2 lateralh7 oi the line of travel otE the Hight so that it passes over the trigger elementv 1T. Should the paaaenger thtiiiglitl gssly not li-:mount at' floor l-t. were no sop deviee provided Sueh passenger would he fluire' over the top of the pulley a niihap whieh han frequently oeeurred with eerious,l results. 1With the Stop adjust'- ment herein diselosed. should the passenger not dislnount from the taStly-inovine' elevator at top floor 14. the weight ot r'ueh passenger will Cause the extension 1:2 to hear so firmly against the angle lever l5 as to overeome the resistance of spring ttl thus allowing the extension l2 to engage element 1T and hautit upward with the helt travel to position as Shown in Fig. l.
