HANGER POE OVERHEAD TRACKS.

' HANGER FOR OVERHEAD TRACKS.

To all whom it may concern:

, Be it known that I, DAVID TOLTON, a subject of the King-of England, and a resident of the city of Guelph, Province oiOntario and Dominion of Canada, have invented certain new and useful Improvements in Hangers for Overhead Tracks, of which the following is a full, clear, and exact specification.

This invention relates 'to means for suspending an overhead trolley or track, and especially to a self-adjusting hanger, which is placed in position on the supportin bracket or eyelet, and in en a ement with t e track, without the use of olts, screws, washers or other like'parts.

One ob'ect of the invention is to rovide a hanger w 'ch may be hooked over t e closed loop or eyelet of a bracket 'or eye-bolt after 'the latter is secured in place, and which, when so hooked, is completely closed around it, so that it cannot be accidentally dis laced.

Another object is to provide a anger which has a practicallyuniform cross-sectional. strength throughout its length.

A further object is to provide a hanger which adjusts itself to the track and grips the same, without'aid' of bolts, screws, washers, or other like arts necessitatin the use of wrenches or similar tools while anging the track.

' The invention consists in the matters hereinafter set forth; and more particularly I pointed out'in the a pended claims.-

Referring to the rawings, Figure 1 is a view in'cross-section through an overhead track rail, suspended from a fixed bracket or .loop by a hanger which embodies the features of the invention. Fig. 2 is a view in detailof one of'the members of the hanger. Fig. 3 is a view in side elevation of aportion of the track-rail, and of the hanger.

In the drawings, A and B com rise a pair of oppositely disposed, detachab y engaged members'constituting the hanger. The u per portions of said members are opposite y turned hooks a, and b, whose outer faces are suitably ribbed and flanged for the intended load, and whose proximate faces are plane and slightly convergent. Said hooks are so proportioned and designed that when in position they form a closed eyelet which encircles the supporting bracket or V-loo C. They 'are secured each to each by ben able Specification of Letters Patent.

lugs 11 and b and b 1 Thedepending shanks of the hooks are ob-.

o and bein halved together, the upper lips (I. and b o the resultant notches being eX- tended past the outer margins of the opposing shank and inturned at their extremities a and b to form hooks or pro'ections which revent lateral displacement 0 the members.

he edges of the lips (F -b are in horizontal alinement and form'bearings on'which the members rock. The lower ends of the members are inturned and form aws ab parallel to said edges and to the lane. of the u per hooks. These jaws are a apted to con orm or fit closely into the angles formed by the u per flange d and web (1 of the track rail D w i'ch is of the usual I-shape in its central portion. Where therail is provided with lateral flanges 61 the members of the hanger are each fitted with downwardly extending lugs d b which bear against the faces of the rail web and resist any torsional or tilting effect of anunequally loaded trolley running on the lateral flanges, and said lugs may be used with good effect where a simple channel or I-beam is used. The members of the hanger are thus in reality, tongs, whose u per arms form a closed eyelet around t e support, and whose lower aws embrace the upper flange of the track rail, the point of suspension, oint of application of load and the bearing eing so relatively disposed that the tendency. of the jaws is to grip the rail harder under increase of load.

In operation, the members are oppositely registering with apertures a v hooked over the support and their shanks interlooked, with the jaws closing on the rail. The lugs of the hooks are thus forced through their respective apertures, and the parts are secured by bending the lugs over the adj a cent ribs by tapping with a hammer, the 'aws adjusting themselves to the thickness 0% the web of the rail, and the lugs holding the hooks together as closely as the spread of the jaws allows.

One advantage of the invention is the fact that the hanger, when in place, is in effect a closed eyelet encircling the support from which it is suspended, thus precluding the possibility of accidental displacement.

closing tongs, the upper Another-advantage of the invention is thev placed in positionwithout the use of wrenches or the like, and are locked in place with ablow of the hammer, thereby adding greatly to the. ease of installing an overhead system for carriers, whose parts are in a measure dif'ficult to reach and hard to adjust in proper relation because of the inaccessibility.

It is evident that where the construction calls for a removable hanger, the hooks of the .upper part may be turned in the same way,

thus a owing a section of rail to be lifted temporaril from the fixed brackets together with the angers thus leaving clear head room, as over a door, or the like.

I claim as my invention 1. A hanger for overhead tracks comprising two oppositely disposed members whose upper ends are oppositely turned hooks which together form an eyeletencircling the hanger support, and whose lower ends are opposing aws, said members being crossed and fulcrumed on each other between their ends to form self closing tongs, and being detachably interlocked at the pivotal point.

' 2. A hanger for overhead tracks comprising two oppositely disposed members inter. locking and rocking on each other between their ends to form self-closing tongs, the upper ext'remities of said members forming a closed eyelet encircling the hanger support,

: and the lowerends beingtwo opposing track j aws 3. A hanger for overhead'tracks com risingtwo oppositely disposed members ha ved etween their ends and rockingv on together each other at the line of contact to form selfortionsof said members being 0 positely ent to form an eyelet encircling t e hanger support, and the lower endsbeing opposing trac jaws.

,4. A hanger for overhead tracks-comprising two members which cross each other between their ends and are fulcrumed on each other at the point ofv crossing to form selfclosing tongs, said members being detachably and m'ovably interlocked at the intersection bylugs inte rall bers, the lower on s o said'mefnber's being inturned mating jaws adapted to grasp. a rail web between the rail flanges, and the uppositely disposed lugs integrally formed on the mem'-' flanges, each other and detachably and movably per ends of the members being bent transversely to the plane of the jaws into hooks which close past each other and encircle the hanger support the proximate faces of the members being in contact only at the fulcrum point.

5. A hanger for overhead tra'cks comprising two members detachably interlocked between their ends, the upperparts of said members being bent past each other into an eyelet, and the lower portion of each member being obliquely ofiset and crossing the corresponding portion of the opposed members, their lower ends being inturned to form mating jaws, said members being so fulcrumed on each other at the line of interlocking only and forming tongs so that said jaws close on an interposed object when said members are suspended by the eyelet.

6. A hanger for overhead tracks comprising two members rocking on each other be-.

tween their ends, said parts being detach-w ably interlocked at the pivotal point by op-v formed on the members, and being obli uely offset and crossing each other below their pivotal point, inturned, mating jaws on the lower end, and oppositely turned, corresponding hooks, transverse to the plane of the jaws,-

whose lower portions cross each other, said members being fulcrumed on each other be tween their ends, and detachably and movably interlocked near their pivotal points by lugs integrally formed on each member, the lower ends of the mcmbersbcmg inturned .turned, mating jaws, and the upper ends,
