. ELEVATORSAEETY DEVICE.

To all whom may concern:

Be it known that I, GEORGE S. iMoGYoRs,

a subject of the King of Hungary, residingV 'at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in `Elevator Safety Devices, of which the following isa specil ication This invention relates to certain new and useful improvements 1n elevator-.safety de- Y vices. f

The primaryr object'of this-invention is to provide means carried by an elevator car automatically actuated upon a breaking of the hoisting cable for the purpose: of'lockingly tents of the car.

Ararat-,r Object of the inveaaon'is the provision of oppositely slidable springpressedbolts carried by an elevator vcar and being retained retracted by means -Of engaging rods when the hoisting cable issupporting the car, the said rods being' automatically released upon a-severing of the-cable, and; 'whereby individual kprojecting means l for the said Vbolts position thelatter in locking engagement with the sidebeams of the shaft.

vWith thesey general objects in view and others that will appearas the naturewof the invention isloetter understood, vthe same Vconsists in the novel combinationfand arrangement of, partsjhereinafter 4more fully de- Vscribed, 'illustrated in the vaccompanying side beams of the shaft. Fig. 2 is av vertical drawings, and pointed out in the'appe'nded claim. f

In the drawings forming apart ofthis application and in which 4like-designating characters'refer to corresponding parts throughout the several v1ews1-F1gure 1 1s afront elevation of an elevator car provided with the present device and partially Vbroken away, the same being positioned between the transverse sectionalview thereof. Fig. 3 is a view similar to Fig. 1, but lwith the elements in their locked position as assumed when the cable is broken. Fig. 4 is a detail transverse vertical sectional view through the upper portion of the caras normally positioned,

vthe top thereof.V the opposite-outer ends 15 of .which are adapted for sliding'upon the guide strips 11. The bottom 16 of the car is provided with a similar transversely positioned beam 17 upon the lower side thereof,

and its opposite ends 18 arearranged to slidably-engage Athe strips 11 similar to the arrangement I described in connection with the upperbeam 14E. l

The car bottom 16 is provided at opposite points withV chambers 18, each of the same having a right-angular form of locking bolt 19 mounted therein, the engaging arm 20 of the Vsaid bolt kbeing slidably positioned througha slot A21A opening at the adjacent outer edge 'of the vcar'bottom andv in alinement with the adiacent guide strip 11. A spindle 22 is provided upon the bolt 19 eX- tending inwardly in alinement with the locking arm 2O thereof andfis slidably journaled in aperforated bracket 23 within the chamber, while an expansion spring 24 encircles the said spindle and bears between the lockingkbolt andthe bracket23. A vertical slidable rod 25 is slidably mounted at each side of the car through vertical alining perforations 26 and 27 in the upper and lower beams-14 and 16 respec- .such bolt,y when the `'bolt` is retracted. A resetting lever 29 is provided for each of the bolts 19, the said levers being pivoted as at 30' to the adjacent' portion of the car and having a pivotal link connector 31 between the lower end of the lever and the projecting arm 32 of the locking bolt. B v this construction, it'will bek seen that when the rod 29 is engaged within the-perforation 28 of its respective locking bolt, the said bolt will be retained retracted and at which time its spring k24 will be compressed, while an upward movement of the rod 25 will release the locking bolt, thus allowing its spring 24 to automatically project the bolt, and whereby the same will engage the adjacent one of the rsaid guide' strip notches 12. By outwardly moving the lever 29, the spring will beagain compressed and the perforation of the boltbrought into alinement With-the.Av e. adjacent rod Which may "be` positioned .therethrough by the means hereinafterset forth.

with upright brackets 33V in the bifurcated tops 34 on vwhich oppositely iprojecting'le- 1- vers 35 are freely piyoted, While the Vopposite outer endsiof the levers 35Y are provided with' longitudinal slots 36' hav-ing transverse bolts mounted therein which areV secured to theV upperf free ends vof. the rods 25. The

inner ends; of vlthe` leversV 35 are pivoted to: anupright (post: 38 slidable; through the top offan archfshaped bracket 39`car`ried"by the `top beam'l of thev `car,"the hoisting cabletO being'securedwithin atop ringv il l.of the said post.' The pestis also'lprovided'f with a" lower ring-42 "having" a. normally 1 closely coiledrctractile spring 43 Vliavingione of itsends securedftherein' and its otherY end j secured lto a stapley le centrally arranged upon -th'e saidfbeaml. ly Opposite lugs 45 are arrangedy uponthe bracket 39 and` oppositelyarranged chains Y 46' are connected betWeen'th-e saidlugsfand staples 47 which are positioned upon oppo z site sides of-'the postadjacentthe` ring 41 thereof; A

From this'detailed description of'theV de'- .vice,the` complete operati-onof thes'ame will be at'once apparent'in-j-that a disengage-v ment 'of` the side rod 25`l from the locking bolts automatically alloWsa projecting of the bolts into Y. locking engagementlwith the notches l2, it 5beingv understood that ythe said .f rods 2 5 are retained intheir 'lovv'e'A locking "positions by=means of' the levers S55-WhenV the inner ends thereof are in their upper positions being held by the V'cable- .idas best illustrated 1n Fig. 1. ln the'event that the.
