Forbes, Sharon, Pa., assignor to West inghouse Electric & Manufacturing Company, East Pittsburgh, Pa, a corporation of Penn sylvania Application October 16, 1936, Serial No. 105,923 1 Claim. (Cl. 248—221) This invention relates to hangers for mounting electrical apparatus. . I An object of this invention is the provision of a hanger for mounting electrical apparatus on 5 supports. 'Another object of this invention is the provi spaced relation for cooperating with the spaced bolts 32 and 34, respectively, in retaining the hanger on the support M. The opening 36 is an elongated slot, the lower end of which termi sion of a hangerfor mounting electrical appa mates in an enlarged opening suitable for re ratus having enclosing-cases of different shapes on supports of different sizes and shapes. This invention, together with other objects, will be better understood from the following de ceiving the outwardly extending end of bolt 32. The lower opening 38 is an elongated slotsimilar to the elongated slot portion of opening 38 and 10 terminates in an enlarged opening provided in the ?ange member 26 for receiving the outwardly extending end of‘ bolt 36 as the hanger i0 is mounted on the support 54. Since the openings 36 and 38 are in spaced 15 relation similar to bolts 32 and 3d, the hanger 10 may be easily mounted on the support it by scription when taken in conjunction with the ac companying drawing, in which: Figure l is any elevational View illustrating an 15 The face l8 of the channel member i6 is pro vided with a plurality of openings 35 and 38 in assembly in which the hanger embodying the features of this invention is employed; Fig. 2 is a top plan View of the assembly illus— trated in Fig. 1; ' ' Fig. 3 is a side elevation'al View of the hanger embodying the features of this invention; Fig. 4 is a top plan View of the structure shown in Fig. 3; Fig. 5 is a rear elevational View of the hanger shown in Fig. 3; and Fig. 6 is a bottom plan View of the structure 25 shown in Fig. 3. Referring to the drawing, and particularly to Figs. 1 and 2 thereof, this invention is illus trated as comprising a hanger it} for mounting 3 O electrical apparatus such as a distribution trans former IE on a suitable support M, such as a wood, concrete or metallic pole or standard. In the drawing only the case of the transformer is shown, it being understood that the case is suit 35 able for carrying the bushings and other attach ments associated with the case. As illustrated in Figs. 3 through 6, the hanger it comprises an elongated channel member it having a face 53 and side walls 29 and 22. The ends of the face of the channel member [6 termi nate in flanges 24 and 26 for receiving the trans former l2, as will be explained more fully here inafter. In order to seat the channel member I6 on the 45 support it, the side walls 23 and 22 of the chan nel member terminate in outwardly extending flanges 28 and 38, respectively. The ?anges 28 and 313 function as feet for seating the channel member E6 on the support I4. In order to carry the hanger it], bolts 32 and 50 36! are disposed in spaced relation through the support iii. One end of each of the bolts extends outwardly from the support for receiving the hanger, as will be explained more fully herein 55 after. so seating the feet 28 and 36 of the channel mem ber on the support that the ends of bolts 32 and 31! register with and project through the enlarged portions of openings 36 and 38, respectively, in the channel member. When the openings 36 and 38 thus receive the bolts 32 and 34, respectively, the channel member may then be slipped down over the projecting ends of bolts 32 and 34 to a 25 position where the bolts are retained in the elon gated slot portion of the openings 36 and 38. With the hanger H! in this position, it may be secured to the support It by so tightening the bolts that the bolt heads engage the face I8 of 30 the. channel member. In order to hang the transformer 52 on the hanger, the ?ange 24 of the hanger H) is pro vided with an opening or socket [it for receiving a pin 42 which may be provided on the case of 35 the transformer !2. The ?ange 24 carries down wardly projecting side walls 6 and 8 so disposed as to seat against the face [8 of the channel member “5 to support the ?ange in its outwardly extending position. Other means for supporting 40 the ?ange may however be employed. The pin 42 may be carried as an integral part of the case of the transformer l2. In the modi ?cation, shown in Figs. 1 and 2, the pin 42 is carried as an integral part of a ?ange 44 which 45 is secured to the case of the transformer near its upper edge in any suitable manner such as by welding. As shown a plurality of ?anges are disposed in spaced relation about the case of the transformer. The ?anges 44 in this position aid 50 in maintaining the cover of the case in position. A cover holding lug 48 is associated with each of the flanges 44 and is so positioned that one of its ends engages the cover of the transformer I2 and the other of its ends engages an associated 55 2 2,114,876 ?ange 44. Each of the lugs 48 is secured to an associated ?ange 44, by means of a bolt 50, in a position where it clamps the cover on the case. In addition to aiding in maintaining the cover in position on the case, the ?anges 44 also serve as hangers, from suitable channel members and angle irons. The hanger member may be easily mounted on the support, as explained herein before, for receiving the transformer. Although this invention has been described lifting hooks for lifting the transformer. with reference to a particular embodiment there The lower ?ange 2B of the hanger l0 carries a of, it is not, however, to be limited thereto except bracket 52, the sides of which terminate in ?anges - insofar as is necessitated by the prior art and or feet 54 and 55 for seating against the side of the scope of the appended claim. 1O the transformer case. An opening 58 is provided I claim as my invention: in the bracket 52 for receiving a bolt or stud 60 A hanger for mounting transformers on sup~ which is carried on the transformer case. ports, the case of the transformer being pro When the pin d2 engages the socket 40 in the vided with lifting pins and retaining bolts and upper ?ange 24 of the hanger, the transformer the supports with spaced retaining pins, com 12 is supported on the hanger in the position il prising, a channel member having spaced feet for 15 lustrated in Fig. l, with the feet 54 and 56 of the seating on a support, the channel member having bracket 52 seated against the case of the trans openings disposed in spaced relation in its face former and the bolt 6D projecting through the opening 58 of the bracket 52. In order that the transformer may be mounted on the support in a plurality of positions with respect to the sup port, a plurality of the bolts 66 may be disposed in spaced relation around the case similarly to the spaced ?anges M. By providing the feet on the channel member and on the bracket, the hanger may be employed for mounting transformers having round, octa gon or square cases on supports of different shapes. Further, by providing the spaced feet on the channel member at a distance from the face thereof, it is evident that the hanger may be employed with supports of different sizes, since the opening between the spaced feet and face of the channel member is of a size sufficient to receive supports of small circumferences while the feet are so spaced as to satisfactorily seat on supports of large circumferences or on supports which have substantially ?at surfaces. The hanger may be easily fabricated from a 40 single sheet of material, or in the larger types of for receiving the retaining pins to removably re tain it on the support, a ?ange carried by each end of the channel member and projecting out 20 wardly therefrom at an angle to the face of the channel member, one of the ?anges having down wardly extending side walls seating against the face of the channel member for supporting the ?ange in its outwardly extending position, a sock 25 et in said one of the ?anges for receiving in en gagement one of the lifting pins of the trans former to hang it, a bracket carried by the other of the ?anges extending upwardly from the ?ange and being substantially parallel to the face of the channel member for receiving the trans former case, spaced feet carried by the bracket for seating the case when the transformer hangs from the supported ?ange, the bracket having an opening therein for receiving one of the retaining bolts of the case whereby the case may be locked in its supported position to prevent movement of the case to cause the disengagement of the lifting pin and socket.
