INSULATOR SUPPORT.

Application filed December T ((ZZ who In Z' may GOHCGWL:

Be it known that l, ARTE-ina Jinenronr, a citizen or" the United States, and resident of the city of St.. Louis and State 01"' lfiissouri, have inventod certain new and useful Improvements in Iusulator Supports, of which the following is a specification containing a full, clear, and exact description, leteence being' had to the accompanyin drawlngs, 'forming a part thereoit.

h v invention relates to improvenents in insulator supports and has for its primary object an insulator support which can be secured in a brick Or stone wall without employing wooden plugs, expansion bolts or similar astening means.

A 'further Object is to construct an insulator support which is held within a briclc or stone wall by 'fr.tion and to which various types of porcelan or glass insulators can be attached, and one which can also be used as a cable support.

In the drawings:

Fig. l is a perspective view of my device;

Fig. 2 is a side elevation of the same showing it in position within a brick wall and with one type of insulator attached thereto;

Fig. 3 is a top plan view of a modified form of support and Fig. l is a side elevation of the same showing it in position in a bricl wall.

In the construction of my device I employ a body of resilient metal 5, this body which is preterably of 'fiat material has its one end 6 bent at right angles to the main body forming a head, the portion 6 is provided with an opening 7 which is to permit the insertion of a bolt for securing the insula tor thereto, in the body and near the portion 6 is a second opening 8 which is also for the purpose of attaching an insulator, this is clearly .hown in Fig. 2. The end OI" the body 5 opposite the upward portion 6 is slitted forining a plurality of tongues 9, 10 and 11, these tongues have their ends 12 terminating in substantially 'the same hori- Zontal plane, but their intermediate portions are alternatelv bent upward and downward as at 13 so as to occupy more space than the thickness of the material from which the support is made In Figs. 3 and e I have shown a form of support which consists of a bodv portion 14, its forward end terminating in a cyiindrical portion this cylindrica-l portion is provided with a Sci'ew threaded portion 16 which extends at right ano-les to the cylindrical' portion and with a boss 17 which is i or driving purposes, the real' end oi' the plate 14: is provided with tongues 18. 19 and 20 which are (ronstructed similar to the tongues 9, 10 and 11 adjacent the forward end of the body portion 14; are tongues 21, these tongues are 'for the purpose or preventing a plate from tipping or rocling after it has been inserted in the wall. 22 and 23 represent adjacent bricls and 241# the mortar Or cement between them.

In securing' my device to a lol-ich oi' stone wall, the mortar betweenv two adjacentbricks or Stones is dug out to a predetermined depth depending entlrely on the distance that an insulator is to be from the wall, the ends 12 of the tongues 9, lO and 11 are then inserted in the Opening thus made, a hammer is now brought into action and the device driven in, the bent portions normally 13 occupying more room than the space between the bricls causes the tongues to assume the position shown in Figs. 2 and 4, and to bind tightlv against the bricks and hold the support i; position lVith the device shown in Figs. 1 and 2 the spool insulators 25 are preferably used but if it is desired to support a cable, the end 6 is turned in he position indicated by dotted lines in Fig F2 and the cable laid on the body -portion 5, it may then be secured by passing a Wire through the opening's 7 and 8 which will prevent the cable from becoming detached thercfrom.

The insertion of the device illustrated in Figs. 3 and i is identically the same but in this instance the tongues 21 furnish an additional support near the forward end of the plate or body and prevents it from tilting.

I may also employ the tongues 21 on the device shown in Figs. l and 2 without departing from the spirit of my invention.

iy device is held in the wall by means of frictionset up by the tongues when the devce is driven in position, of course, it is not 'Inserted in the horiemtal joints of a wall, .i

Still it is obvious that the Same may be inserted between the joints that are either Vertical, Or in any Other position Without departng rom the. spirit of my invention.

Having fully described my invention, What I Claim is l. An insulator Support coinprising a fiat body portion formed of spring metal and provided on one of its ends With a portion extending at an angle to the body portion, a tongue carried by each -edge of the body portion, and an intermediate tongue carried by the body porton, the said first mentioned tongues and the interniediate tongues being bent in opposite directions SO as to occupy inore space than the thickness of the body portion.

2. An insulator support comprising a body portion formed of flat Spring metal provided at the rear end With tongues 'ormed integral 'tllGl'BWtl1 tongues ornied on the body portion between the first mentioned tongues and the opposite end of said body portion, all of said tongues provided With bent portions so as to ocoupy lnore space than the thickness of the body portion, and means 'tor securing an electrical conductor to the front end of the body portion.

3. An insulator support comprsing a body portion of flat resilient material pro-- vded at One end With an insulator attaching means, and adjacent its Other end With a plurality of bent portions, a plurality of bent portions intermediate the ends, all of said bent portions so arranged as to normally occupy a greater vortioal space than the thickness of the material Whereby Said Support is frictionally held in position Without the use of extraneous aStening means.

4:. An insulator support coniprising a fiat booy portion of resilient material provided at one end With a plurality of: integrally foi'nied tongues so bent as to occupy more space than the thickuess of the material, the other end of said body portion provided With an insulator attaching means arrang cd at an angle to the body portion, and a plurality of tongues int-erlnediate the ends of Said body portion, said tongues arrangcd to normally occupy more space than the th lokness of the body portion and adapted to be Compressed When the support is placed in position, all of said tongues adapted to hold the device in position Without the use ot extraneous fastening means.

5. A device of the class described coinprising' a fiat body portion ot spring material having one end bent at an angle thereto thereby orming a head, an integral tongue torined on said body portion, said tongue having its free end extending toWard the head and norlnally spaced apart from the body portion, and electrical Conductor Supportng means carried y Said head.

In testinony Whereof, I have signed lny name to this specification.
