UNITED sTAiissgie Aram ortica l 7 JOHN xARifrzKY, or* GARWooi), `NEW JERSEY, Assreiion'ro Gzinwoon coMrnNYn Y 1 c r i CORPORATION or NEW` JERSEY.,

To'dZZ i0 7mm 'it may concern Be it known that I, loi-in 7Kaizi'rZini', a lcitizen or the'United States, and residing at .Garwood, in the county of Union and State of New Jersey, have` invented certain nevv and` useful Improvements .in Toggles, or which the following is a specification, taken f in connection Withthe accompanying dravving. i v j i Y My invention relates to toggles and more particularly to atoggle in which the hinge member can be readilyplaced or changed the mechanic. It `further relates to such 'a toggle in Which` the hinge member is not as byy by the operator toinsert the hinge'niember,

or' if a hinge member is already mounted in the head he. can readily remove itin case he desires to substitute another form of jhinge member. g i My invention further relates to` 'such a spring headed` toggle which is stampedout of sheet metal.: At the same time thatit is stamped, or subsequently,vit may; be` provided with seats for the hinge member and also, though not necessarily, With :one or more stops. These stops are preferably formed by crimping over one orboth or' the free ends of the arms of theh head so that they will engage With thebolt or other niemberand insure the proper alinement of the `head With the bolt When it is `inserted in the hole in the Wall. y

` My invention further relatesto .aftoggle which is stamped from sheet metal and `in which some of the metal is crimped orbent Within the body `ofthe head to makevone end of thev head heavierthan the other end, and also to addstrength to the complete toggle. f `Y My invention further relates toy certain details of construction andr combinations which will be more 4'fullydescribed `in `the specification and pointed out in the claim,`

headed bolt shown in FigplOgv Y. In the illustrative leniliiodiinent oi `my in-V vention lis a head of a toggle ` bolt having ends 2 and 3 lof vsubstantially the `saine length, with a hinge member@inuntedfsbstantially equi-distant between theV ends 5 and 6. This toggle headfinay Vhe in various Waysprovidedtheends Q and v3y are of practically the same lengthv and th'e' 'pi vl oting member or hinge memberis 'mounted so thatthe strain upon they endQ willbali ance thestrain or tension upon the end when the toggle head is mounted inthe Wall as shown for Venample in' Fig. 9. .To insure` thatoneV end vof the toggle head will oven balance the other, so that the4 heavier end will drop into its proper operative position, as shown in Figs. 1, 2, 3 and 9, I may in any suitable manner increase the weight'of one of the ends as, for example, 'the end number 2. This of course may be done in various ways.

For ease, economy a'nd speed in manufacture, I form my toggle head from stamped sheet metal. I take a blank such as 7, Fig. 5 and bend it at 8 to ferm the interior reverse U shaped member 9 and thenagain bend the blank at 10-10 to form the side 11--11 of the head shown in Figs. 2 and 3. At the time the blank is stamped, or subsequently, I preferably provide it with hinge seats to coperate with the hinge inember, whatever that form of hinge member may be. One form of hinge seat, and the one that I preferably use, is 1.2-12`formed by stamping out a portion of the blank.

When the blank is bent as shown in Figs. 2 and 3, the end 2 will overbalance the end 3 even though Athe two ends are of the sam-e length. This is due to the fact that additional or surplus metal is formed into the head of the toggle on the end 2 and-not on the end 3. This additional bend or crimp of the metal forming the U shaped member 9 also strengthens the entire toggle head while not interfering with the operator moving out the arms 13-13 toinsert, or change, the pivoting or hingejmember.

This hinge member may be the square nut shown in Figs. 1 and 2; or the diamond shaped nut 14, Fig. 3, in whichl the ends 15m15 ofL the nut are, in effect, trunnions; or the hinge member may be a true trunnion nutllG, Fig. 7, having trunnions 17-17; or

the hinge member may be a T headed bolt 18, Figs.- 10 and 11 in which the T head 19 would be made to coperate with'the seats 1.2-12, or any other suitable form of hingel member may be used. The hinge member, in F igs. 10" and 11 is put under tension by the nut 20 cooperating with the screw `thread 21.

I preferably, though not necessarily, provide one or more stops on the arms 13 so that they will engage with the bolt 22 to keep the toggle head 1` in alinement with the bolt while it is being inserted in the hole 23, Fig. 9. These stops 24 are preferably formed bending over one or both of the free ends of the arms 13-13. p

It is often desirable to use 'toggle bolts in walls orA partitions or'similar locations 25, Fig. 9, in which the free or vair space 26 is limited. It is found that it is often not feasible to use an ordinary toggle bolt, having ends of unequal length to insure that the bolt will drop into its operative position as shown for example in Fig.- 8, for the reason that the air space 2G is too narrow or limited. By my invention, in which the two ends of the toggle head are of equal length, it can be mounted in a wall where the airspace 26 is of minimum width.

\ In these walls or partitions, which are quite frequently made of hollow tile, the drill will start to drill the hole 23, Figs. 8 andi), of the correct diameter until it has penetrated a certain distance from the face 27 of the wall.` Further drilling will cause the hollow tile, or other material of which the wall is made, to break away and fall on the interior of the wall leaving an irregular funnel shaped opening 28. l The contour lof this opening will vary with the material of the wall and the resistance met.

m In Fig. 8k I have shown an old form of toggle bolt having a 'riveted nut 35 and a head 29 in which the end 30 is of greater length than the end 31, this being the common expedient in the trade to ofvelbalanceV one of the ends to insure that the toggle head will assume a. vertical position in the wall as shown in Fig. 8. It has been found in practice that a toggle head having ends of unequal length, 'as for example 30 and 31, will often assume, in time, and under severe service conditions a position like that shown in dotted lines in Fig. 8, particularly if the work 32, to be held is subjected to vibration. This will permit the work to get loose and rattle. If the vibrations upon the work 32 are excessive, in this form of toggle head having unequal ends, the toggle head tends to work down into parallelrelation with the bolt 33 and, in time, Vwill work out of the hole 23, permitting the Ywork 32 lto drop with consequent damage and danger.

y my invention theto'ggle head 1 having'ends 2 and 3 of equal length will straddie'v the opening 28 and the strains f and stresses on the ends 2 and 3 will balance so that there will be no tendency for it toassume a'position similar to that'shown in Fig. 8, Vor to work parallel with the bolt 22 to permit the work rattling or falling.

Having thus described this invention in connection with illustrative embodiments hereof t0 the details of which I do not desire to be limited, except as required by the scope of the appended claim, what is claimed as new and what is desired to secure by Letters Patent is set forth in the ap-V pended claim.

An article of manufacture comprising a head of a toggle bolt stamped from spring sheet metal and provided at one end Vwith a reversed bent or crimped portion to make that end heavier and stronger` than the other end.
