Application filed November 27, 1908. Serial No, 464,897.

To all whom it 'may concern:

lie it known that I. llriiiiliaii T. Lone, a citizen ot the l`11ited States, and a resident .of Sumner, in the county of Pierce and State of TVashingtonv, have invented new and useful linproveinents in Elevators, of which the following' is a t'iill, elear, and eXaot deseription.

My invention relates to elevators and it has t'or its object to' provide iiii'pi'ovenients whii'h may be iised on elevators or for other purposes. ln my elevator' l provide a carriage, a frame. being' provided to travel in 'fe'iiides in the carriage, a yoke being' disposed 'in the 'ti-aine` two clamps being' p ivoted to ilihefyoke," the clamps being' also pivoted to `the frame, and means being' provided to liinit the niovementot' the yoke and to niove 'the l'raine relatively to the carriage.

Still other objects of the invention will ap- ]fiar in the tiillowingl complete description of the intention.

in this speciication l will describe the preferred forni of my invention, ont it will be understood that l do not liiiiit myself thereto as consider myself entitled to all Jorins and embodiments of the invention which may be held to fall within the scope ot' the appended claims. f

leterenee to be had to the accompanying1 drawings Vtoriniiin' a part of this speciication. in which similar characters otA referi-iicel indicate corresponf.Y I parts in all the figures, in wliich- Figure l an eevaiuin :ir' :he invention, parts of the sains being alie-wn in section; Fig. is aectional view on the line 2 2 of Fig'. 1 Figi'. 2i is :i sectional View on the line 23MB oi Fig'. l: and itin' i is a. sectional View on the line Ll---l ot Fig. l.

By reti-riding to the drawings. it will be seen that standards 1 are provided, these standards 1 being' preiierably in the 'forni ot cables. but it will be understood that other 'forms ot standards may be provided, withoutdeparling from the scope o' the inveii` lion. The standards 1 are disposed `in guides il, the Aguides being composedot` oppositely disposed guide members 3 which are pivoted ,ltofgether in pairs, there being web nien'ibers v`l oppositelv disposed guide members S around f the standards 1i the oppositely disposed e'iiide members having interlocking` ineini 'and lit in `grooves 40 in the beads 26 oi the bers (i which have a sliding` vertical engagenieiit with interlocking members T 0n the carriage In the iipper oppositely disposed guide members 3, there are locking` members t) which slide horizontally therein and have protruding surfaces 1() by which they may be operated. The locking members 9 are ada pled to slide over the interlocking members T to hold the interlocking' members i5 and T in normal position and prevent the detachmein of one from the other, The locking members 9 have springs 11 which 'are provided lo keep thein disposed over/the interlocking ineinbers i'.

The carriage 8 has'inner obliqiiely disposed lraides 12, there being;l guides in pairs at either side of the carriage, one pair be,

carriage obliqiiely lwith reference to thestandards l, but keeping substantially parallel therewith at all times. disposed in each of the frames 1.3, the yoke .15 being movable within the Jframe but being iii close Contact therewith at its' lower and upper extremities. The yoke 15 has 'protruding members 16 which have guides at their terminals and are disposed in close proximity to the standards 1. ln the rear of `the yokes, there are stops 1T which pre vent` the abnormal rearward movement. ot the yokes. i y

To each oi the yokes 15 are. pivoted elainps 1S, one at either side of the yoke, one o't' the Clamps 1S having a portion 19 which is disposed between portions i2() of the other clamp, a pin Q1 passing' through the. upper and lower portions of the yoke 15 and through the portions 19 and 20. `Each ot the clamps 18 has an extended lateral poi-' "orifices in each ot' the ciii'ved portions 2i' yoke 15 is' bead 2li which is disposedv hands rlhe hands have their' concave claim as new and desire tosecureby Letters taces coi'ruaated to enable them to obtain a latent tiriner hold against the standards 1. Springs 29 are secured to the carriage 8, said springs being' adapted to pi'ess the 't'iaiiies 13 upwardly toward the respective standards l.

Through the carriage 8 is disposed a sup-i porting` bar it), which passes through guides 3l in the carriage, the supporting 'bai' 30 being pivoted to two levers 32, each lever 232 being` pivoted to the carriage and commanding one otE the 'trames 13, a link 33 connecting' the othei' armof the levei' 32 with the top of the traine 1?). The supporting bar 30 passes through the bottom of the cai'- riage and to it is secured substantially at right-angles, a stop 34., having); a plurality of rods 235 secured thereto, the rods passing' through the bottom ot the carriage 8 and haviimV heads 36` at their Yfree terminals and springs 3T ai'e disposed on said rods, the springs 3T being provided to act as cushions when the i'ods il?) are pressed downwardly. To the supporting;l bar lt) is secured by a pulley 3S, or by other means, a cable 39.-

In using my invention, as for instance in an elevator, it will be seen that on any breakage of the cable 3), the trames l?) will be free to inove upwardly and will be directed in this direction by the springs Q5), and inasniuch as the trames 12% travel in the Kguides l2 which move upwardly toward the standai'ds 1. the trames '13 will travel toward t-lie standards, but they will be substantially pai'- allel thereto during their iiioveiiientainasmuch as the 'frames travel in `guides not only at their top but. also nair their bottoms. As the trames lil move toward the standards l, the yokes l5 carrying` the clamps t8, will also move in that direction. but'. almost immediately the movement of the yokes will' be checked by reason of the Jfact that the protruding; members lt willalmost immediately come in contact with the standai'ds l. rlliis will prevent t-lie t'iirthei' movement of the yokes and the portions (if the clamps which are pivoted by the pivots 21- will Abeheld stationary, while the latei'al siii't'aces 22 of the clamps will continue to move outwardly in the rQ'eneral direction ot the standards l. thereby causing the clamps 18 to swing on the pivots F21, which 'forces the hands Q5, secured to the clamps, against the standards l, thereby clutching' the standai'ds 1. During -this movement 'ot the trames 1?), the supporting' bar 30 `has been moved downwardly, thereby causing' the heads 3G ot' the rods 35 to move toward the lower surface, ot' the carriage 8, which action as has been stated, compresses the springsv 37 and prevents any yrapid movement of the clamps 18 which miglfit canse a shock to the operating mechanism or to thesti'ucture to which it may be secured.

Having thus described my invention, l
