SUPPORTING MEANS FOR OVERHEAD TRACKS.
Application filed August 15, 1927. Serial No. 213,159.
It is the object of myinvention to provide new and improved means-tor supporting overhead tracks; and, further, to provide a hanger plate in such supporting means ar ranged to be conveniently attachedto the flanges of I-beams of various sizes. 7
The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:
Fig. 1 is an end view of my improved device, the I-beam and the track being shown in. cross-section on the line 1-1 of Fig. 2.
Fig. 2 is a side elevation of the same, partly broken away.
Fig. 3 is a vertical cross s'ection of my improved device, taken on the line 3-3 of Fig. 2, and partly broken away.
Fig.4 is a plan view of the hanger-platc of my improved device.
Fig. 5 is a bottom view of the same; and, Fig. 6 is ahorizontal cross-section of an exemplified track structure, partly broken away, showing an application of my improved device. 2
In practice I-beams of different heights have flanges of different widths, the related heights and w1dths having 1n practice become standardized. Instancmg I-beams six inches, seven inches, eight inches, nine inches, ten inches and twelve inches, I-beams of these respective heights in practicehave flanges whose widths are respectively three inches, inches, 3.66- inches, four inches, 4.33 inches, 4.66 inches and five inches.
I have provided a hanger-plate which is conveniently secured to a variety of sizes of I-beams, the aboveanentioned sizes of I-beams being selected as anexample, although my improved hanger-plate may be arranged for I-beams of different sizes or for difierent ranges of sizes. Thus in Fig. 6, the I-beam '21 may be instanced as a12 inch I-beam, and the I-beam 22 as a 5 inch I-beam.
My improved hanger-plate is exemplified at 25. It is provided with apertures 26,
which. are arranged in substantially elliptical form about a common center.- The centors of the apertures maybe on a line which is substantially elliptical. The hanger-plate may be ofelliptical form. The apertures are arran ed in )airs the a ertures of the redifferent sizes.
having heights respectively of, five inches,
spective pairs being at opposite sides of the common center, and the pairs of apertures being located for acconunodating I-beams of Thus I'have designated opposite apertures by the numerals 5, 6, 7, 8, 9, 10 and 12, corresponding to the sizes of I-beams hereinbetore mentioned. The flanges of I-beams of the respective sizes are acconnnodated between the aperturesso designated respectively by the respectivesizes of the I-beams specifically mentioned. The apertures for the smaller sizes of I-beams are adjacent to the minor axis of the ellipse and the apertures for the larger sizes of I- beams are adjacent to the major axis of the ellipse, the apertures for intermediate sizes being arranged therebetween.
The hanger-plate is arranged to be received across the bottom of the I-beam to which it isattached. Clamping shoes 28 are received above the opposite edges of the lower flange 29 of theI-beam. These clamping shoes are provided with rabbets 30, havg ing an upperwall 31 correspondingin form to the form of the upper surfaces at the respective edges of the flange 29, and an outer wall 32. corresponding in form to the form of the outer edges of said flange. The shoes are'respectively provided with apertures 33.
Bolts 34- are received throughthe complemental apertures 26, corresponding to the size of I-beam to which the hanger-plate is secured, and through the apertures 33 in the clamping'shoes, nuts 35 being received about the bolts for clamping the hanger-plate and the shoes to the I-beam. -The bolts have heads 36 of polygonal cross-section, and the lower ends of the walls of the apertures 26 in the plate are correspondingly formed, so as to prevent rotation of the bolt in the plate. The heads of the bolts are shown square and are provided with inner ends, the walls of which slope toward the threaded shanks of the bolts, the apertures 26 being complementally formed. I
If the hanger-plate is to be secured to a five inch I-beam, the bolts are received in the holes marked If the hanger-plate is to be secured to a six inch I-beam, the bolts are received through the apertures marked 6 in the hangerplate, and if the hanger-plates are to be secured to I-beams of other sizes, the bolts are received in apertures marked correspondingly 5 on the hanger-plate.
on the hanger-plates. The outer ends of the heads of the bolts are preferably received wholly within the apertures in the plate, so that there are no projections beyond theplane ol' the lower ace of the hanger-plate, in order that the hanger may be secured to said lower tacc so as to extend in any direction desired. Such a hanger is shown at it. and comprises an attaching flange 42, a shank i i. and a track-lug it.
A bolt to is received through a central aperture 46 in the hanger-plate and through an aperture 47 in the flange 42. It lochwasher ib and a out it) are received about the threaded shank of the bolt, tor clamping the flange rigidly to the hanger-plate, in order to properly locate the hanger.
The head 51 ot the bolt to is countersunk in the upper surface of the hanger-plate, so that the upper face of the hanger-plate ma rest against the lower tacc oi the I-beam. The head St is prcl'erabl v polygonal in erosssection. the wall of the aperture to being correspondingly shaped, to prevent rotation oil' the bolt in its ai'ierture. The inner end oi' the head slopes toward the shank of the bolt 4-5, the upper end of the wall of the aperture to being complementally 'i'ornied.
A track 54: secured to the track-lug, the track-lug having a vertical face against which the track is clamped. as by means of bolts 5t). received through apertures in the track and in the track-lug. and nuts 57.
The track is a flat strip of metal. and is arranged either straight or along various curvatures, according to the directions in which itis desired to convey the goods suspended from the track. These goods may be carcasses and animal parts in a slaughter house or meat; packing plant, or other goods, and the goods may be supported by a frame mounted on rollers traveling on the track, these not beingshown as they are wellknown.
The center of the aperture 46 is substantially coincident with the center about which the apertures 26 are arranged in the hangerplate. When so arranged. the ai'ierture 46 is central with relation to the I-beam. regardless of the size of I-beain to which the hangerplate is secured.
The track-lug off the hanger is so placed with relation to the aperture t? in the at tachinn' flange 42 of the hanger, that when the track is fixed to said track-lug. the center of the track and said aperture 4-? are in line with each other, so that, when the hanger is attached to the hanger-plate. the center of the traclt is in line with the center of the I-beam. wherelr inaxin'uun rigidity is secured, and tilting strains are avoided.
Hanger-plates and hangers are selectively placed along the straight portions and the curved portions of the track so as to properly support the track, the portions of the track at the hangers and hanger-plates being centrally located below the hanger-plates.
