PIPE HANGER.

Application led May 31,

My inventionrelates to a pipe hanger of a simple construction, which renders the same readily applicable as to position, and enables the pipe to be quickly adjusted at the desired level with an expenditure of time and labor which are both negligible.

The invention also 'comprises a constructon in which the weight of the pipe supported by the hanger is utilized to effect a iirm engagement of the parts constituting the hanger, with the result that when the pipe is placed in position in the hanger the elements of the hanger are interlocked in such manner as to effectively support the pipe.

An' advantageous feature of the construe tion of my improved hanger lies in the facility with whichthe locking means may be disconnected when it may be desirable to remove the pipe froin" the hanger, inthe event that change in the location thereof becomes necessary.

The novel features of my invention will be pointed out in the appended claim.

In the drawing which is attached hereto,

Figure 1 is a view in perspectiveshowing one of the improved hangers as supporting a section of pipe;

Fig. 2 is a view of the hanger in side elevation, parts being broken outso as to Show Vthe structure and arrangement;

Fig. 8 is a front elevation, partly seo# tioned, showing the separated elements of the hanger and illustrating the manner of their assembly;

Fig. l? shows in perspective view one of the locking keys in its preferred form; and

Fig. 5 is a similar viewshowing a modication in the form of the locking key.

Referring now to the drawing, the numeral lO indicates a section of a length'of pipe about which will be placed a suitable numf bei' of my improved-hangers for supporting I the pipe at the desired level.

The hanger .is comprised of a metallic band 20, designed to encircle the pipe,A the' projecting ends 30, 30, of the band being eX- tended in substantially parallel planes from the point near which the ends of the band approach each other, so as to provide means Vfor attaching the said band to the pendant 4,0. The latter member `is formed as a metal strip, the upper end of which will be firmly secured tO any Suitable overhead 1921. Serial No. 473,634.

support in any ina-nner which may be deemed satisfactory to the person engaged in the work of placing the pipes in position. The number of the hangers'einplo-yed and their dimensions will be in proportion `to the Y. load which they are to carry.

rout its lengtlnor a portion of its length,

with perforations 60, which are in registry with the like perforations in the ends of the band 20. y

In applying the hanger to the pendant 40,

so as to sustain thepipe, the ends 30, 30, are

sprung apart and the band is 'passed about the pipe, the several bands for each length of pipe being located thereon with respect to the previously placed fixed pendants 40.v The pipe isthen lifted into position, the lower endY of the tween the ends 30, 30, of the hanger, and the perforations 50, and`60 brought into pendant being entered be 1 alignment. A locking key 70, is -then in'- serted inthe aligned perforations to retain the several parts in the position desired.

The locking key 70, which is employed as a means for connecting the parts, may be formed as a rectangular piece of metal, having in its upper edge a notch SO, the side walls of which may be inclined, as indicated at 90, in Fig. `t. It will kcontribute to the eiliciency of the locking action to havethe length of the bottom of the notch less than the aggregate thickness of the ends 80, 30, and the pendant 40., when these parts are assembledv and brought into engagement with each other, asvshown in 1., In such position, the key rests against the bottom of the opening 60 inthe pendant 40, and the top portion of the vslots 50 'in the ends oftheband 20, bear against the iind clined Surfaces 90, .of the key. The'strains thus inducedby the gravitation of the pipe uponthe fixed -pendant 4:0, are centered in the key 70, with the resultV that the inclined los Y surfaces 90 formed upon the key bear with a Wedging action upon the outer sides ot' the ends 30, 30, and press the latter closely into engagement with the opposite sides oit the pendant 40, so that an effective interlocking of the parts is attained.

it is not, however, essential to practical results, that the notch in the lie" 70 be formed with inclined Walls, inasmuch as the purposes ot' my invent-ion will be fully achieved by using a key provided with e notch having vertical side Walls 91, as shown in Fig. 5. ln such construction, the strain imposed bythe gravitation oi the pipe cui be transferred to the bottom ot the notch, then engaging the top portions oit' the perforations 50, with the vertical walls 9]. et the key in engagement With the outer sides of the ends of the band.

Although I Yhave shown the assembled structure in Fig` l, as including a pair oit locking keys 70, it Will be clearly Within the scope of my invention to use a single key for the attainment ot the purposes thereof.

rEhe provision in the pendant d0, oi pertorations which in number exceed that with which the ends of the band 20 are provided, creates a desirable latitude permitting the adjustment ofthe level of the pipe.

En dismantling an assembled structure, it is necessary only to relieve the key 70 ot the strains imposed thereon by the weight of the pipe, re-align the perforations inthe mrts, and Withdraw the key.

Having thus described my invention what claim and desire to secure by Letters Patent the United States, is:

A. pipe hanger comprising a band for supporti g a pipe, the said band being provided n th perforated ends which extend in subs al parallelism from one side thereof, perforated ined pendant arranged between the projecting ends of the band, a notched key passed through the aligned pertorations to connect the band to the pendant, the side Walls of the notch being inclined 1' i torce the said ends into engagement tn the sides of the pendant under the avitation oi the pipe.

in testimony whereof, I have signed my naine atl ltiilwaukee, this 27th day of May,

JOHN P. SEYFERT,
