TRACK FOR DOOR RANGERS.

Application filed .Tune 25, 1928i. Serial No. 288,233.

My invention relates to new and useful improvements in track for door-hangers of the type comprising a plurality of trackforming sections supported in operative position adjacent the top of the door-frame in longitudinal alinement with each other, by means of brackets connected with the doorframe, and is fully described and explained in the specification and shown in the accompanying drawing, in Which- Figure 1 is a view in elevation of my improved track.

Figure 2 is an enlarged view in elevation of two adjacent alined sections of the track together with the bracket at the joint therebetween, portions of said sections being broken away between their ends.

Figure 3 is a section taken at the line 3 on Fig. 2 and viewed in the direction of the arrow.

Figure i is a section taken at the line 4 on Fig. 2 and viewed in the direction of the arrow.

Figure 5 is a rear view of the structure shown in Fig. 4.

Figure 6 is a plan sectional view of a portion of the top member of a door-frame showing it as equipped with my improved track of which two adjacent alined sections only with a bracket at the joint therebetween, are shown, portions of these sections being broken away between their ends and the bracket being shown partly in section.

Figure 7 is a section taken at the irregular line 7-7 on Fig. 3 and viewed in the direction of the arrows; and v Figure 8, a perspective view of a key for locking together the adjacent ends of the track-sections.

In the arrangement shown 9 represents sections of a hollow cylindrical track, these sections being longitudinally alined to form a continuous track. Each section 9 is open at its bottom to form a slot 10, the slots of the several sections 9 being longitudinally alined. The sect-ions 9 are of a type adapted to receive within them door-hangers (not shown) the rollers of which extend into the interior of the sections and run along their lower portions, and projecting port-ions of which hangers extend downward through the slots 10 to engage the door which they support.

Disposed at intervals along the track at the joints between the sections 9 are supporting brackets 11 for attachment to the top of the door-frame and with the aid of which the sections 9 are assembled into a complete track. The ends of the track may be supported from the door-frame in any suitable way, as by brackets like the brackets'll, and where the sections 9 are of such length that support thereof intermediate their ends is necessary or desirable, supporting brackets may be provided at such locations.

The brackets 9 are each formed of two

sections

12 and 13 which overlap the joint between adjacent sections 9, the section 12 being shown as formed with a rear face 1li` at which it flatwise bears against the face of the top-member 15 of the door-frame. The bracket-section 12 contains in its upper end a vertically elongated slot 16 to receive a fastening device, hereinafter referred to, the front face of this bracket-section being shaped to present an outwardly-facing concave seatA 17 for the rear portions of the track-sections 9, the section 12 adjacent the upper edge of the concave seat 17 being beveled, as represented at 18.

The front bracket-section 13 is formed, at its upper end, with an upwardly-extending plate-portion 19 at 'which it bears fiatwise against the face of the upper portion of the section 12, the portion 19 being apertured, as represented at 20 to receive the fastening device herenbefore referred to and represented at 21, this device being in the form of a bolt passing through the aperture 21, slot 16 and an aperture 22 in the framemember 15.

The lower end of the bracket-section 13 is forwardly deflected as shown and presents a rearwardly-facing concave seat 23 bearing against the front portions of the adjacent sections 9, the rear face of the portion of the section 13 adjacent the upper extremity of the seat 23 and represented at 24C, being so disposed as to fit flatwise against the surface 18 of the section 12.

The section 13 at its portion 24 and the section 12 at its portion 18 contain alined apertures to receive bolts 25, which, together with the bolt 21, rigidly hold the bracketsections tightly clamped against the tracksections 9.

Each track-section 9 contains at points set in from its ends two apertures 26 shown as slots with their long dimensions extending crosswise of the axes of the sections 9, these apertures being provided to receive at the joint between adjacent sections a key 27 shown as in the form of a yoke the crosspiece 28 of which spans the joint between the sections 9 and the legs 29 of which extend into, and closely fit, the apertures 26, the key 27 serving to lock the sections 9 against relative rotation and relative longitudinal movement.

The apertures 26, are so disposed that when longitudinally alined to receive the key, the slots l0 in the sections 9 will be in alinement, as shown. By providing each section with a plurality of apertures in each end, as shown, the provision of alternate sections 9 with slots 10 dissimilarly arranged relative to the slots in the sections with which they alternate is'rendered unnecessary with the Vmanifest advantage. f

The keys 27 project beyond the outer sur 'faces of the sections 9 and Vthus form projections to receive which the inner concave seat 23 of section 13 is recessed as represented at 30, this recess being preferably of such size and shape, as shown, that the key substantially closely fits it, whereby van interlock is presented between the bracket and the adjacent sections 9 preventing rotation of the sections 9 in the bracket and the shifting of these sections lengthwise therein. By this construction all of thesections 9 are held in mutual alinement by the connections therebetween and with slots 10 in the desired position to accommodate the door-hangers. Thus a firm and substantial track construction is afforded which can be readily assembled and which can be made entirely devoid of projecting brackets, which is of particular advantage in packing and shipping.

Furthermore by employing the key-connections as described, the brackets are devoid of projections for holding the track-sections against longitudinal movement or rotation, with the manifest advantage. y

While I have illustrated and described a particular construction embod ing my invention, I do not wish to he un erstood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. In a sectional door-hanger track, the combination of a series of aligned track sections, supporting brackets located at the joints between said sections and each formed of separate sections between which said track sections are clamped, means holding said bracket sections in position about said track sections, and members projecting from said track sections beyond the side surfaces of the latter, said brackets containing recesses to receive said members for interlock therewith in the clamping of said bracket sections to said track sections.

2. In a sectional door-hanger track, the combination of a series of .aligned .track sections, a supporting bracket located at the joint of said track sections and formed of separate sections between which said track sections are clamped, means holding said bracket sections in clamping position about said track sections, and means for interlocking said track sections with said bracket comprising interlocking portions on said bracket and track sections adapted to become relatively positioned for interlocking upon assembling said bracket sections with said track sections.

3. In a sectional door-hanger track, the combination of a series of aligned track sections, a supporting bracket located at the joint of said sections and formed of separate sections between which said track sections are clamped, means holding said bracket sections in position about said track sections, and a member projecting from said track sections beyond the side surfaces of the latter, said bracket containing a recess to receive said member to interlock therewith in the clamping of said bracket sections to said track sections.

4. In a sectional door-hanger track, the combination of a series of aligned cylindrical hollow track sections slotted for the passage of a door-hanger, a supporting bracket located at the joint of said track sections and formed of separate sections adapted to clamp said track sections between them, fastening means securing said bracket sections together, and means comprising interlocking portions which interlock said track sections with said bracket sections against relative rotation of said track sections upon the assembling of said bracket sections and said track sections, said interlocking portions closely tting each other and so disposed as to interiit in the relative movement of said bracket sections into clamping position.y i

5. In a sectional door-hanger track, the combination of a series of aligned cylindrical hollow track sections slotted for the passage of a door-hanger, a supporting bracket located at the joint of said track sections and formed of separate sections adapted to clamp said track sections between them, a fastening device on the rear yone of said bracket sections, and means comprising interlocking portions which interlock said track sections with said bracket sections against relative rotation of said track sections upon the assembling of said bracket sections and said track sections, said interlocking portions closely fitting each other and so disposed as to intertit in the relative movement of said bracket sections into clamping position.

6. In a sectional door-hanger track, the combination of a series of aligned cylindrical hollow track sections slotted for the passage of a door-hanger, a supporting bracket 1o- 5 cated at the joint of said track sections and formed of separate sections adapted to clamp said track sections between them, a fastening device on the rear one of said bracket sections and extending forwardly 10 thereof for securing said bracket sections together, and means interlocking said track sections with said bracket sections upon the assembling of said bracket sections and track sections comprising a recess in the outer one of said'bracket sections and a projection on said track sections adapted to closely it in said recess, the Walls of said recess being substantially parallel with the longitudinal axis of said fastenin device.
