Specification of Letters Patent.

Application filed December 22, 1916. Serial no. 138,374.

To all whom it may concern:

' Be it known that I, HOWARD B. SHERMAN, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of lliichigan, have invented certain new and useful Improvements in Conduit- Hangers; and I hereby declare that the following is a full, clear, and exact descriptionv thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in hangers for pipes, conduits, electriocables, and like objects, which I will hereafterrefor to under the general inclusive term conduits. The objects of the invention are to provide a novel and'very simple and easily applied means forsuspending such conduits from. I-beams and the like 1n a convenient,

safe and substantial manner to avoid cumbersome and complex constructions; and to provide hangers which can be applied by unskilled workmen, and by which the conduits can be suspended either parallel with or at right angles to the I-beams or'supports. The invention provides n0velclamp-members adapted to be engaged with the edges of the'I-beam flange; tie-bolts rigidly connecting the clamp-members; and novel means for suspending the conduit from such tie-bolt. I

Itis very important that the clamp-members' shouldbe stiff and rigid so that they will not bend or drop away from the flange .when the tie-bolt is tightened; and the tiebolts must be sufficiently strong to bear the strain, and must approximate in length the width of the flanges, which vary greatly.

In the accompanying drawings I have illustrated a practical embodiment of the invention and will explain same with reference thereto and summarize in the claims the essential features and combinations of parts for which protection is desired.

In said drawings I Figure 1 is a view of the complete hanger attached to an I-beam; the hanger-ringbeing arranged so that the conduit will extend longitudinally of the beam.

"Fig. 2 is a similar view showing how the hanger-ring can be arranged to suspend the conduit at right angles to the beam.

Fig. 3 is a ferred form of hanger-ring detached.

Fig. 4 is a perspective view of one of the clamp-members detached.

perspective view of the pre- Fig. 5 is a view showing a form of hanger used for cast 1ron pipe or heavy objects.

Fig. 6 is a detail sectional view of part of Fig. 5.

' The clamp-members may be formed in any desired manner as by casting or'stamping out of suitable metal. Each clamp member preferably has an oblong base or outer portion 1 surrounded and stifiened by an inwardly projecting flange 1*. In the sides of this flange near its top are notches 1 adapted to engage the edges of the flange of an I-beam, I, or othersuitable support, as shown in Figs. l2--5. The upper edges of said notches rest upon the top of the flange and support they clamp-members thereon,

and the lower edges of the notches underlie the flange of the I-beam as shown in Fig. 1. The portion 1 of the clamp-member is perforated as at 1 below the notches 1 for the passage of a tie bolt '2. The clamp members, by reason of their peculiar formation,

are very strong; can be readily cast; and

will securely engage the flange.

Similar but oppositeclamp-members are engaged with opposite edges of the flange of the beam, and the tie-bolt 2 extends through the openings 1 in the clamp-members and is secured by means of a nut 2 on its threaded end, exterior to one of the clamp-members as shown. By tightening this nut 2 the clamp-members are securely engaged with the flange of the I-beam. I

The portions l of the flanges of the clampmembers underlie the flange of the I-beam and prevent the clamp-members from tilt: ing thereon, and enable the tie-bolt to draw the clamp-members squarely, and, tightly against the edges of theI-beam and clamp them securely thereagainste Before the tieboltis engaged with both theclamp-meme with a nut a as usual in clamps.

Opposite the said opening the hangerring is formed witha radially projecting bend or loop 3 which may be directly engaged with the bolt 2 as in Fig. 2, so as to suspend the hanger-ring at right angles to the length of the bolt and parallel with the PatentedOct. 30, 1917.

length of the I-beam, and when the loop is thus engaged with the bolt the conduit C, suspended by the ring, would extend longitudinally of the bolt and at right angles to the I-beam. The sides of the loop 3 however are perforated as at 3* for the pas- 'provided of 'dillerent sizes;

sage of the tie-bolt, and may be engaged with the bolt 2 as indicated in Fig. 1'; and whenso engaged the hanger-ring will be suspended from the tie-bolt in a plane parallel with the bolt and at right angles to the I-beam so that the conduit suspended thereby will extend at right angles to the bolt and longitudinally of the l-beam. This novel perforated loop of the hanger-ring is of great practical utility as it enables the hangenring to be readily suspended directly-from the bolt either at right angles thereto or parallel therewith, so that the conduit can be arranged either loi'igitudinally of the I-beain or transversely thereof.

l Vherc very heavy oonduits are to be suspended, or it is desired to suspend a conduit from beams arranged at ditlerent elerations, the devices shown in Figs. 5 and 6 may 'be'used. in this instance in place of the hanger-ring 3 a ring 5 is used, said ring having perforated ears 5 connected by means of a bolt 5 to an eye 6" on the lower end of a casting 6 having a threaded socket 6 screwed onto the lower threaded end of a rod 7 the upper threaded end of which rod is screwed into a threaded socket 8 in a casting-S, having an eye 8' through which the tie-bolt 2 passes.

The'ring 5 may be made of any desired diameter to suit the size of the conduit to be suspended. vThe rod 7 can be made of suitable length to suspend the conduit any desired distance beneath the tie-bolt :2.

The'c-lamp-members enable the bolt to be arranged close beneath the beam, and in the form shown inFigs. 1 and 2 the conduit can be suspended very closely beneath the 1 beam. Withthe construction shown in Fig.

5 the conduit can be suspended any desired distance below the beam.

, The hangers can be readily attached to flanges of various widths, by using tie-bolts of suitable length. Hanger-rings can be and they also can be readily adjusted either parallel with or at right angles to the tiebolts.

Thehangers being very simple can be readily attached to an I-beam or suitable support by ordinary unskilled workmen.

ll hen su'cha' hanger is properly fastened to an I-beam, as shown in the drawings, it is stiff and'rigid; w ll not bend or drop topics or thisnatent may be obtained for from the flange; is not liable to loosen; will remain securely in place and will substantially support the conduit in position either parallel with or at right angles to the beam.

lVhat I claim is:

1. In a hanger, opposite clampmembers each having abase portion and inwardly projecting flanges notched to engage the edge of a support, and said base being perforated below the notches tor the passage,

of a tie bolt; in combination with a tie bolt passing through the perforations in the clamp-members; and a'hanger ring having a radially extending loop with perforations in its sides, substantially as described.

2. In a hanger, opposite clamp-members each consisting of a base portion having projecting side flanges provided with notches the ring can be suspended from thebolt in a plane parallel with the bolt.

3. A clamp-member for the purpose specified, having a baseportionand an inwardly pro ecting flange surround ng this base portion, said flange being provided with notches in its opposite sides'adapted; to engage the edge of an l-loeam to support the clampmember thereon, and said base port on being perforate d below said notches for the passage of a tie bolt, substantially as described. V

4. A clamp-member for the purpose specified, consisting of a base portion and in wardly projecting flanges on: the sides of sald base portion, said flanges beingprovided with notches adapted to engage the edge of a support, and said base having a perforation for the passage of a tie bolt elow said notches when the member is in position for use, substantially as described.

5. A hanger-ring-tor the purpose specified having a radially projecting open loop adaptedito engage a bolt, the sides of this loopbeing perforated, whereby the ring can be suspended either by catching the loop over a member, or passing the member through said perforations in the loop.

In testimony that Iclaim the foregoing as my own, I aflix my signature.
