CONNECTION FOR TRACK RANGERS.

Application filed April 11, 1927.

My invention relates to connections for hangers adapted to sustain overhead trackwaysupon which carrying devices are to run, and it especially relates to means to connect these hangers to overhead supporting'structures used in the frames of buildings, such asJI beams ete., and it consists of means whereby said trackways may be supported and laterally as well las vertically adjusted on said supporting structures. Also,

of other features in the construction of connections for track hangers which will be hereinafter set forth, and will be definitely defined in the claims.

In the accompanying drawings, forming a part of Vthis specification, F ig. 1 is a vertically disposed transverse section of a structure embodying` my invention, a portion of thestructure being broken away, as will be hereafter explained. Fig. 2 is the same of an upper portion of Fig. 1, some of the parts being shown in a different position. Fig. 3 is a vertically disposed section on line 3 3 of Fig. l looking in the directionl of the arrow at the upper end of the line. Figs. 4 and 5 are perspectives of certain parts which will be hereafter described;

Referring to the drawings, A A'represents the lower flanges of van I beam, such asfare used' in the construction of the metallic .frame work of buildings, and B is a small portion-of the central web. of the I beam, the main portion of the web and the upper flanges ofthe beam being broken'away.' C is a'track-rail of vordinary construction which is connected to the I'beam as follows.,

A pair of clamping members D D heldv together mainly by a bolt E, are arranged to have their lower ends catchover and Vhold the bead Lon the upper portion'of the track rail C 'in' the usual manner. These clamping members are fitted `with a link Fhaving its lower ends open and tted :with heads which are adapted to enter 'and hold in recesses in the innerfaces of the clamping members D D and to..be adjusted to lengthen and. shorten the hanger in the usual manner, the link'F and the clamping members D D thus arranged,YY being generally known in the art as track hangers.

My invention relates tothe method of conneeting the links F of said track hangers to` the Ibeam's or other supporting member, forming aportion of the framework of the Serial No. 182,682.

building inwhich the track-rail C the bolt.

These clamping members H are fitted.` on' their upper ends with inward'l'y' extending lugsl L ,t which are' adapted to'catch over' the upper edges of the flanges ofthe I beam when used, and to be held in contact therewith by thenuts'or burrs J, screwed onto the ends of the bolt G. this means the-link F and the clamping member D holding the beadA of the track-rail "C between them, will be securely connected tothelflanges'A A-of the I beam. To make the hold on theflanges of the I beam more secure, the portions z.

of the clamp-1H, below the bolt G, are

lengthened' inwardly to'form braces which' will counteract thel pressurev ofthe inwardlyl extended lugs It on the upper edges of the flanges A.

In order'toholdv the track hanger, com'- posed` ofthe link Fand clamping member D, morerigidly in position, I use la central member, preferably composed of twoparts-K K fastenedi'together by meansy oa rivetL,

or in place/of the Vrivet-a` bolt may 'be used. The inner sides of the lower portionsof'tl'ie parts If are hollowedfou-t vto admit the'link F, and also to permitl the passage ofthe bolt G through the link. The members are preferably made 'taperingl on'the outer sides,'as shown by I `igs.l 1 and 11, with their lower ends closely fitting theflink F', andl with invvardl'yY projecting portions K` coming in contact with an upper portion of the link.

The members'Kare preferably held in Contact with'the'lower surface ofthe flanges A' of the I'beam by means of the bolt Geoming in'contactwjth shoulders -K K on' said Also, to hold' thel members K more securelyin place, the upper ends are broadened andthe central `part is prefermembers.

ably liollowed out, asshown inthe'drawings. If preferred, the members K'may Vbe made integral with its center cored secure the results specified, and w made the. rivet L will not be nee-fled;

When installing; the traeleri-l," it? out to herr se freioo quently necessary to adjustl it laterally as well as vertically. The vertical adjustment has already been largely provided for by the type of track hangers composed of the link F and clamping members D. To adjust the track-rail laterally all that is necessary with my invention is to loosen the nut or burr on one end of the bolt G, and to tighten the nut or burr on the other end, as shown by Fig. 2, which shows a lateral adjustment of the track-way C and its attachments in one direction. To adjust it in the opposite direction, simply reverse the operati-on. The longer the bolt G and its threaded ends, the greater the adjustment which may be made.

The members K assist in holding the traclc rail more securely in its lateral adjustment by preventing the swinging of the track hanger, and it also assists in preventing the tipping of the track-rail, as it is sometimes liable to do when carrying a'heavy load over a curved portion. My invention may also be used with other forms of frame work where metallic I beams are not used by dispensing with the clamps H, and using other form of connections known to the art, which are adapted to be connected to the other torms of framework, such as wooden beams and the like, and which will provide for lateral adj ustments.

My invention ymay also be used to make a slight vertical adjustment of the position of the track-rail by tightening or loosening the nutsgo-r burrs J, the tightening tendin to draw the curved portion of the bolt up kc oser to the I beam. This adjustment will of course be limited by the heads of the members K, but for some uses the members K may be dispensed with and then the vertical adjustment may be increased. With any nodi-cations which may be made my invenion is extremely simple and effective in operation.

I'Vhat I claim as new and desire to secure b y Letters Patent is:
