. SUPPORTING-BRACKET.

Be it known that I, CHARLES E. MILLER, a

' citizen of the United States, and 'a resident of Pittsburgh, in the; c'ounty of Allegheny and State of Pennsylvania, have made a new and useful Invention in Supporting-Brackets, of which the following is a specification. This invention relates to supporting brackets of devices and more particularlyto insulator supports.

It is now common to make up insulator supporting brackets, from standard metal shapes or sheets. In certain types it is de-' sirable to' secure the'same tothe mounting element (a pole or side of a building) by 3 means of a single screw (either a wood screw,

'a lag screw or a bolt) and various schemes have been devisedfand tried out for providing the bracket or arm with such a screw or bolt. "In making up such brackets or supporting devices it is. desirable to use stand- "a part of this application.

ard-shapes such aschannel. sections and la'tes or sheets and considerable difficulty has been experienced in providing brackets made from standard shapes with a suitable screw or bolt. l I An object of this invention isto provide simple and eflicient means for rigidly 'secur-Y to a-' ing a screw 'or. bolt of standard pattern supporting arm or other. fixture. A further object is to produce an insulator support, made up of standard material and having a standard screw or bolt as an element thereof. .A stillffurther object is to provide simple and efficient means" for rigidly'fsecuring together a supporting arm, a base or fulcrum plate and a screw orbolt to fform a'rela tively cheap supportingybracket or device.

These as well as other-'objectswhich will readily appear to those skilled in this particular art I attain in the devices illustrated in the drawings accompanying and forming In the drawings, Figure 1 is a: view side elevation of an' insulator support embodying this invention, Fig. 21s'a View in sectional elevation of the same and Fig.3 is

Fig. 8 is a view in. perspective or" a screw. and illustrates the man-- ner of treating'the same -tor use with supportingaarms made from relatively thin stock.

made in accordance with "this invention. Fig. 5 1s a. front v ew .in-elevation of the same. Fig. 6 is a view .in section taken on line 6-6 of Fig. 4:"and Fig. 7 is a view in sectional elevation of another form of supporting device embodying'this invention.

This invention is applicable to a great Va riety of devices and for the vpurpose of illustration but with no idea of limiting it I have shown it applied'to three types of supports.

The device shown in Figs. 2 and 3,,conslsts of a supporting arm 8 struck from a standard channel section, a base or fulcrum plate 9 stamped from sheet metal. and a standard wood screw 10 the head of which has been squared. In order to rigidly secure the three elements together the base of the channel is punched or cut away leaving the ends of the

sides

11 and 11 to serve as 'tenons, the channel base being also punched to provide aslot conforming to the squared head pprtion 12 and adjacent shank portion 13 of a standard screw. This it will be understood may either be a wood screw, a lag screw, or-any desired: form of bolt;

The screw is inserted in the slot made for its reception inthe channelbase and on ac count of its head portion being squared is. prevented from turning in the slot. The base or fulcrum'plate 9 is punched with three

holes

14, 15, l5.v Hole 14 is of a size and shape to snugly'fit the upper shank portion of the screw and-the slots or

holes

15, 15 of a size'to fit the tenons l1, l1, After-the 'screw is assembledin the supporting arm the base plate is sl pped over the screw (the shape'of which is preferably tapered), the

tenons'projecting through

holes

15, 15 beyond the base plate and thescrew, projecting through the center 14.. The tenons are then riveted overand the structure is thus completed. -Forlthe purpose ofinsuring that the screw shall be rigid with respect to the.

iis'inventicn. The curved arm 1? is rom a ch: nnel section and is punched so as to provide tenons 11 and l1 and slot for the reception of the screw. Base plate 9. arm 17 secured together in the manner above de- :cribed with relation to Figs. 1 to 3. A

in Fig. 1'" l ha e shown a. supporting memier having an eye piece 18 punched from sheet metal and provided with an eye 19, a slot for the reception of screw 10 and-the tenons 11, ll. the screw are secured togctherin the manner described with relation to Figs. .1 to 3.

Having thus described. my invention what I claim is-- 1. A support member slotted toreceive the head portion of av screw, a screw the head of which lies within said slot, a fulcrum member secured to one end of the support member and provided with a hole through which said screw projects and means for securing said fulcrum member to said support.

2. A support member slotted to receive the head portion of a screw, a screw the head of which lies within said slot and is clenched to said member, and a member secured to one end ofthe support member and provided with a hole through whichsaid screw projects.

3. A support member slotted to receive and the screw are.

Eye piece 18, the base andthe head portion of screw, a screw the head of which lies within said slot and which is clenched to said support member, and a washer pierced to receive said screw and riveted to the end of said support member.

4. A support member slotted to receive the head portion of a threaded securing element, a threaded element having an enlarged head lying within said slot, and an alining member pierced to receive said threaded member and riveted to the end of said support member.

5. A supportmember slotted to receive the headcportion of a threaded securing element, a threaded element having an enlarged head lying within said slot and having its head portion clenched to said support member and an alining member pierced to receive said threaded member and riveted to the end of said supportmember.

An insulator support comprising a support arm slotted to receive the head portion of a screw, a screw the head of which lies within said slot, and a-base plate pierced to receive said screw and riveted to the end of said arm.

'7. An insulator support comprisinga support arm slotted to receive the squared head portion of a screw, a screw the head of which lies within said slot and which is clenched to said arm, and a base plate pierced to receive said screw and riveted to the end of said arm.

tion of a screw and to provide tenons, a. screw the head of which lies within said slot, and an abutment member pierced to receive said screw and tenons and which is secured to said arm by means of said tenons.

9. An insulator support, comprising a support arm slotted. to receive the head por tionot a screw and to provide tenons, a screw the head of which lies within said slot and which is clenched to said arm, and an abutment member pierced to receive said screw and tenous and which is secured to said arm by means of said tenons.

10.. in insulator support, comprising a support arm, a base plate and a screw; the arm being formed of channel s ,ction punched at one end to receive the head and upper shank portion of said scre and to provide tenons, the base plate being pierced to receive said screw and said tenons, the screw head being up set to clench the arm and the tenons being deformed so as to lock said base plate to the end of said arm.

11. An insulator support comprising a base plate, a screw passing through said plate and having its head spaced therefrom, and a supportarm having one end secured to said plate and having a slot spaced from said end embracing the head of said screw whereby alinement of said screw and said arm is maintained.

12. An insulator support comprising a base member, a screw passing through said member and provided with a. polygonal head, and a support arm secured to said member and provided with a slot to receive the polygonal head on said screw the diagonal of said head beinggreater than the greatest width of said slot whereby relative rotation of said screw and said arm is prevented.

18. An insulator support comprising a base member a screw passing throu h said member and provided with a head raving opposite flat portions on its circumference and a support arm secured to said member and provided with a slot to receive the head on said screw the diagonal of said head being greater than the width of said slot whereby relative rotation of said Screw and said arm is prevented.

In testimony whereof, I have hereunto subscribed my name this ninth day of Janu ary, 1918.
