WILLIAM A. HUBENER, OF NEW YORK, N. Y., ASSIGNOB TO DIAMOND EXPANSION BOLT COMPANY, OF NEW YORK, N. Y., A CORPORATION 01 NEW YORK.

AND METHOD.

Application filed February 10, 1925. Serial m. 8,181.

My invention relates to a new toggle and the method of using it; and also to a setting tool, which is preferably employed to set the toggle. This setting tool would ordinarily be sold with the toggles, though the toggles and the setting tool may be sold as separate articles of manufacture.

While my toggle is preferably set with the aid of my setting tool, it is possible to set the toggle by hand if the hole in the wall is large enough to permit the ready grasping the ends of the resilient mem- My invention also relates to setting or positioning-a toggle behind a wall having air pockets, or similar voids, the setting 1 tool being preferably calibrated to indicate the exact length of stove bolt, machine bolt, cap screw, or other securing member, which would have to be used to reach the tog 1e and give sufiicient pull to engage and tig ten the work.

My invention further relates to certain '.;methods, combinations, sub-combinations, and articles of manufacture as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings I have shown illustrative embodiments of my invention, simply by way of example, though it is to be distinctly understood that my invention is not to be confined to these particular forms. In these drawings the same reference numerals refer to similar parts in the several figures.

. In the illustrative embodiments of my invention. shown in the drawings, 1 (Fig. 6) is a toggle head provided with a bolt hole 2 havin interior screw-threads, and on either si e of this tapped or screw-threaded hole, are

holes

3,3 through which a resilient member 4, preferably in the form of spring wire, is threaded to form

arms

5, 5, the end of each arm being preferably bent to form

prongs

6, 6 for a purpose to be hereinafter described. The tog le is also preferably, though not necessari y, provided with a trig er 7.

To position to toggle a hole 8 is drilled, or otherwisemade, within the wall or other support 9 usually formed of terra-cotta, brlck, concrete, stone or similar "matenal. After the hole has been formed the

arms

5, 5 are compressed after first tilting the toggle head so that it can-be passed througlrthe hole in the wall. This compression may be done by the fingers of the operator, who while the parts are in this position, may if the hole is large enough, manually place the tog 1e head, with its resilient member 4, wit in the hole and manipulatethe'toggle head until it passes the interior surface 10 of the wall 9. By then withdrawing his fingers the

resilient members

5, 5 will instantly spring out and engage with the interior surface 11 of the hole 8, as shown for example in Fig. 4. The operator, before releasing the

arms

5, 5, will preferabl draw the arms he toggle head 1 bridge or straddle the hole 8. In this positioning of the parts the bolt 12v can be screwed within the hole 2 to secure the work 13 to the exposed face 14 of the wall or other suitable support 9. When screwing upthe head 15 of the bolt the end 16 of the bolt will engage with the resilient member 4, and move the resilient member slightly to the rear causing the

prongs

6, 6 of the

arms

5, 5 to scrape along the interior of the wall 11. In doing this, however, the toggle bolt Wlll. not be misplaced because the bolt will hold the toggle in proper position and will cause it to firmly bear against the interior or concealed surface 10 of the wall or other suitable support 9.

While my toggle may be set by hand 1n :1. hole suificiently large to permit this operation, in practice I preferably set the toggle head by means of a setting tool, which permits me to employ a much smaller hole 8 in the wall 9, thereby reducing the cost of 1nstallation and in addition positively and quickly setting the toggle head for engagement with the stove, machine, or other bolt, or cap screw.

The method of setting the toggle by means of the setting tool 28 is clearly shown in Figs. 1 to 4 inclusive. This setting .tool

which I preferably employ comprises a sleeve 20 having its inner end provided with locking surfaces 21, preferably formed by spinning the end of the sleeve. lVithin this sleeve 20 I mount a plunger or ejector 22 so as to have frictional engagement with the interior of the sleeve. This frictional enagement, to prevent the plunger or ejector ro pin out ofthe sleeve 20, may be accomplis ed in various ways. I have shown by way of example a cut or kerf 23 in the end of the plun er or ejector 22 and mounting therein a friction member 24 formed of resilient wire having its ends 25, 25 (Fig. 1) bent towards each other and engaging in the hole 26. When the plunger or ejector is pushed into the sleeve 20, these

ends

25, 25 are caused to approach each other, the friction member 24 being compressed and yieldingly engaging with the inner surface of the sleeve 20. This friction, however, does not interfere with the read operation of the plunger or ejector 22, being merely sufficient to hold the plunger or ejector in any position within t e sleeve 20.

To insert the toggle 1 with the aid of the setting tool 28, the toggle head is swung from the position shown in Fig. 6 to bring the trigger 7 adjacent to the upper arm 5 of the resilient member 4 when both

arms

5, 5

are compressed, for example by the fingers of the left hand of the operator, and the

prongs

6, 6 and the trigger 7 are inserted in the end of the setting tool 28 so that the trigger 7 as well as the

prongs

6, 6 engage with the locking surfaces 21 formed on the sleeve 20 (see Fig. 1). The setting tool with the attached toggle head and resilient memher is then threaded through the hole 8 in The parts Will then be in the position shown in Fig. 3, the toggle snapping from the dotted position in that figure to the position shown in full lines. By then pulling out on the sleeve 20, which Wlll carry the plunger or ejector 22 with it, the toggle head is moved to the right of Fig. 3 and caused to straddle or bridge the hole 4. Further pres sure to the right of Fig. 3 will withdraw the tool as shown in Fig. 4. The

prongs

6, 6 will be pulled out from engagement w1th the locking surfaces 21 on the sleeve 20 and will immediately engage the inner surface 11 of the wall, or other suitable support 8, and automatically hold the toggle head in correct position bridging or straddling the hole 8, as shown in Fig. 4.

The work 13, whatever it ma be, can then be secured to the exposed sur ace 14 of the wall or other suitable support 9. l

In screwing up the head of the bolt, the

end 16 of the bolt 12 will engage with the resilient member 4, and as the toggle head is tightened and secured against the inner suroften entails the use of a very long stove,

machine or other bolt. The exact length of bolt needed is hard to determine and requires manipulation of several lengths of bolts before the correct length is found.

a By one feature of my invention I enable the operator to tell at-a glance exactly the correct length of stove or other bolt to be employed. I accomplish this'by calibrating the setting tool.

In Fig. 8 I have shown on a smaller scale, a wall 35 having an air ocket or void 36.

In drilling the hole 3 the operator may find that the portion of the wall 38 is not strong enough to support the work, and therefore he drillsthrough the portion 39, on the other side of the air pocket 36, so that the toggle head will et a firm bearing on the inner surface 40 o the wall or other suitable support 35.

To enable the operator to determine at a glance the exact length of stove or other bolt that will have to be used to cooperate with the toggle head 1, I calibrate the setting tool so that the graduated portion of the tool, which is in line with the outer wall 41, will give the correct reading and show exactly the length of bolt that would have to be employed; thereby avoiding the delay of manipulating a series of bolts of different lengths to determine which one is the correct length to cooperate with the toggle.

For convenience of manufacture, I preferably provide the sleeve 20 with interior or female screw-threads 42, Fig. 9, to cooperate with the exterior screw-threads 43 on the extension sleeve 44 which sleeve is calibrated as shown in Fig. 9. \Vhile I preferably employ a sleeve and an extension sleeve connected together it is of course to be understood that if desired the outer sleeve may be a single member.

Having thus described this invention in connection with illustrative embodiments thereof, to the details of which I do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.
