To all 'whom t may concern.'
Be it known that I, NIC KRUMI, a citizen of the United States, and a resident of Chi` cago, in the county of Cook and VState of v side thereof through a door or other open-V ing which is, at times, closed by a sliding door.
Among the objects of the invention is to obtain a switch which will be automatically operated bysaid door, to-open and permit the door to be closed; to lobtain a switch of thev character namedwhich is simple in construction, containing few parts. easily installed, not liable to become broken or out of rdergfto obtain a-switch which will, when open, be provided with means to prevent a trolley approaching the switch at the open end thereof 'from becoming de-railed; and to obtain a switch which is easily operated, manually, to close it. A A

Fig.A 10 is a top plan View ofthe several g, Lauree parts which are illustrated in Fig. -7,.showlng the cable by which the switch is opened when unlocked from its closed position.v
Arreference character applied to designate va given part indicates' said` part throughout the several figuresof the draw,- Ings wherever the sameappe'ars. i
A, A represents Vsuspended rails appreaching the switch4 at the pivoted end thereof, and B, B', railsapproaching said switch at the'opposite end. X, X', Y, Y', indicate trolley wheels on said rails. Crepresents a chair which is-arranged to support the ends of rails A, A,and also the pivoted en-d of the switch, and D represents a chair at the opposite Vend of the switch, which supports vsaid end when the switch 'is closed, and
also'supports the endsfot rails 13,134. E, E', represent'fthe tracks ofi-the switch, Awhich consist, as represented, ott a singlerail which is bent, (as at 6),.'so thatl the remainder of the rail forms parallel tracksV or rails.` The' ends of the rails A, A are bevelled to correspond with vthe bend e adjacent thereto. -,F representsa slot in chair C, and G a vertically extending bolt which is movable longitudinally in said slot. H, h, represents a combinedrstandard and base', (illustrated. as integral). The bolt vGr is secured' lin the lower end of standard and base H h, and g represents a washer on bolt'G, between the head 'of said bolt and the under side of chair Cf Base'h'is illustrated as resting on vthe flanges of railsE, E', and astirmly secured Yto saidflanges by baril, boltz'l and nut 11 J d,

The upper edge ot the horizontal meinber of bell crank L is in the path of movement of pulley 7e whenk the lever l and pulleys J el, are turned on standard H, as by a sliding door coming in contact with said lever, and thereby said pulley 7c is orced on to said horizontal member ot the bell crank to force said horizontal member down and turn the bell crank on its pivot. rllhe lower end of the vertical member ot the bell crank is thereby moved towards vthe right, as viewed in Fig. 2, and to said lower is attached the rod M, which is, at its other end connected to bolt' m. The bolt m is longitudinally movable in abutment m ot base M. The normal position ot bolt m is Aillustrated in F ig. 2, in whichv positionv it is yeldingly held by spring m. When said bolt is in said normal position the forward end thereof is in a recess-provided therefor in standard N on chair D. Said bolt therefore normally' holds the switch closed,and until by the 'foregoing described angular movement ot lever K and pulleys J d, the pulley is forced on to bellcrank L,'to turn said bell crank on its pivot, to release the switch troni its locked condition, whereupon the switch is automatically opened by the means about to be described. 0 represents a standard` which is secured on base M, and O is a cable or cord which is attached to said standard and eX- tended to'and over the pulleyGf and to the weight 0', (see Fig. 10). P represents a standard which is rotatably mounted on chair l)1 and is provided with the horizontal. member p at its upper end. l represents a forked member which is also mounted on standard l), and 7? is thev recess in said yiiorked member. Villien the switch is closed the standard O is in recess 29', and the horizontal member y? is between and parallel to the rails of the track, so that a trolley may travel along said track. ils the switch is opened the standard, or bolt Q passes out of recess' ya", and in so deine turns standard 'p approximately an annular' distance ot' ninety degrees. thereby turning horizontal.
