TRANSFORMER BOX. AND HANGER.
SPECIFICATION forming part of Letters Patent No. 606,208, dated June 28, 1898.
Applicationfiled November 22,1897. Serial No. 659,426. (Nomodel-l To all whom, zit may concern:
Be it known that I, LUDWIG GUTMANN, a citizen of the United States, and a resident of the city of Peoria, county of Peoria, and State of Illinois, have'invented new and useful Improvements in Transformer Boxes and Hangers, (Case No. 88,) of which the following is a specification.
The object of this new device is to facilirate the hanging of transformers and to reduce the amount of time required for this purpose. It has been the general practice to pro-' vide lugs on the transformer-box to be able to suspend the same. hile this mode is sufficient for attaching it to a wall, other means are required to support it on a pole, on which most transformers are mounted. For this purpose a cross-arm and iron hangers are required. The lugs offer additional inconvenience, as the locating of the holes in a" wall or cross-arm requires the raising of the transformer to its place for marking the holes to coincide with those in the lugs.
Another purpose of the invention is to provide a mode of suspension which may be adopted for all existingeonditions.
To more fully explain the nature of myinvention, the accompanying drawings may be referred to in connection with-the description.
Figure 1 shows a front elevation of the preferred transformer-hanger. Fig. 2 shows a side elevation of this hanger. Fig. 3 shows the same in connection with a transformerbox. Fig.4: is a section through the transformer box and hanger at lines a l) of Fig. 3. Fig. 5 is a modified hanger, and Fig. 6 is a section of this hanger.
Referring in particular to Figs. 1 and 2, the hanger consists of a main plate A, of metalfor instance, cast-iron. It is provided with a number of holes B for admitting bolts or screws for attaching it to a pole, beam, or wall. The size of the plate is so chosen and the holes located in such a manner that it may be readily attached to any wall, crossarm, or to any pole. In the latter case it is preferable to remove the curved surface of the pole behind the plate, so that it can be screwed home on the pole and rest firmly against it. The form chosen is triangular,
and the upper two sidesare provided with a raised portion or rim 0, which has the form of an inverted V.
Figs. 3 and 4 show the application of this hanger. On the back of the transformer-box D is cast a raised rib E, forming an inverted V. This rib is provided with the groove F, (see Fig. 4,) into which the rim 0 may readily slide.
Fig. 5 shows a hanger-plate of rectangular shape. The same may be made to have the flanges G slightly tapering, so as to wedge into a suitably-formed set of grooves on the back of the transformer. (Shown in dotted lines.) Fig. 6 shows this plate and the back of a transformer-box in section. The flanges E on the transformer-box are not parallel, but come nearer to one another at the upper end. The plate just described enters with the smaller end first into the groove F, wedging itself into position asit advances in the groove. This last condition is not absolutely necessary. The sides 0 C may be parallel, as also the grooves F. In this case some means must be provided to prevent the plate A from slipping through at the upper end. These means consist in closing the grooves F at the upper end, as indicated by the dotted lines G G. The Weight of the transformer rests in this case on these twolugs thus formed, while in Figs. 1 and 4 the weightis carried by the entire length of the flanges E E.
This construction m akes the mode of hanging very simple. The lineman takes the hanger-plate of small weight upon the pole or place to be fastened and drives lag-screws into the holes B, thus securely fastening the hanger-plate A. Then the transformer is raised slightly above the plate and then lowered, so that the rim 0 slides into grooves F. The weight of the transformer downward will wedge it on the hanger, from which it can only be removed by again hoisting it up.
It is evident that my invention may be modified in a variety of ways without departing from the nature of the invention. For instance, the lower holes B of Fig. 1 may be substituted by slots extending to the rim of the plate. Further, the shape of the plate or its rim may be given a different form. Therefore I do not wish to limit myself to the exact device shown in the drawings.
Having now fully described the nature of my invention, that which I desire to claim as.
my invention is- 1. In a transformer-hanger the combination of a main body tapering toward the upper end, a tapering rim forming part of said hanger, located in a parallel plane to the main body, and holes or recesses in said main body for retaining screws, bolts, or other devices for fastening, as and for the purpose described.
2. In a transformer-box the combination with a receptacle for inclosing a transformer, 01": a groove or recess provided on one of the sides of said receptacle, a removable plate adapted to be retained in said recess, and means, such as holes in said plate, as and for the purpose described.
In a transformer-box the combination of a receptacle, a projecting rib, or ribs, provided with a slot or recess, a removable plate provided with a rim, normally engaged with said recess, and means, provided in said plate, for its attachment to a suitable support, as and for the purpose described.
I. In a transformer-box the combination of one or more projecting channels extending from a side of a receptacle inclining toward each other, adapted to retain a supporting plate or bracket, and a removable plate or bracket normally retained in said channel, and means, such as holes in said plate or bracket, for suitably attaching; it, as and for the purpose described.
5. In a transformer-box the combination of a bracket or plate, means, such as holes, or recesses forattaching said plate to its place, and a projecting rim, a metallic box provided with an extension containing a recess normally engaging with said projecting rim, but removable from the latter in an upward direction.
6. In a hanger-plate the combination of a triangular main body A, a projecting flange located in a plane parallel to said main body, and means such as holes or recesses in said main body, as and for the purpose described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 11th day of November, 1897.
