SPRING-TOGGLE.

Specification of Letters Patent.

Application filed December 23, 1919. -Serial No. 347,033. n

.To all/whom t may concern.'

Be it known that I, JOHN KARITZKY, a

citizen of the United States, residing at Gar- A wood, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Spring-Toggles, of which the following is a specification, taken in connection lwith the accompanying drawin v y invention relates to toggles. More particularly it relates to means which will insure that the togglev` head will rock or swing at an angle to the arm or bolt, after it has been inserted into `the wall or lother support, v e

Myv invention further relates to a toggle having a head provided with pivoting means midway its length, so that one end does not overbalance the other, and ymeans to insure the rocking yof the toggle head when it has beeninserted in the wall.

, My. invention further relates to a rigid toggle head which is swung upon the pivot- .ing nut by spring means; it Vfurther relates to a rigid toggle headihaving bearings for a pivoting nut, and to a spring cooperating with the nut to hold, the nut within the A bearings.

f My invention furtherrelates' to a rigid toggle head having a pivotedrnut, and ia spring carried by the toggle head having an arm cooperating with, the nut to rock the toggle` head in .relation to the nut. My invention further relates to such a device in which the arm of the spring may be extend ed and bent at an angle' so thatthe arm cooperates not only with the nut but also 'with' the bolt.

My invention further relates to certain combinations kand details `of construction which willY be more fully hereinafter described in the specification and pointed out in the claims.

,In the accompanying drawings the same reference` numerals refer to similar parts vin the different figures.

Figure 1 is a perspective view of my yspring toggle bolt, .one of thefiianges being omitted from the toggle head for purposes of clearer illustration;

F ig. 2 is a vertical section through a wall, y

or other support, 'and the work to be supported showing the manner of positioning the spring toggle `which is shown iny side elevation; f L

F ig. 3 is a vertical section through a wall or other support, and the work supported, the same asin Fig. 2, but showing the toggle head rocked at right angles to the bolt by means of the spring; y

F 1g. v4l is a perspective view of the preferred form ofspring used inmy invention; y F1g. ,5 1s a perspective view of the toggle head; and n i e Fig. 6 is a perspective view of mytoggle head, the same as Fig. l, but omitting the bent-extension of thefspring arm. 1 In the toggle bolts now on the market it 1s customary to pivot the arm or holt to the head sov that one end of the head is heavier than theother. That is, the pivot is not located substantially midway between the endsy of the head. By having one end longer, that end will be heavier. than the other end, and consequently will have a tendency to overbalance' it and causey the toggle head, as soon asjit is pushed home,

to assume an angle tothearm or bolt to i which it is pivoted. Avery slight obstruction inside the wall or support. however will prevent gravity turning the head at right ,angles to the hole, so that the work can be Vsufficient `to prevent the ordinary form of gravity toggle-from operating. Further I can make myV toggle head of minimum length which will not only save metal, andA therefore cost of manufacture, but it will permit my toggle to be vused inthin partitions, or similar walls or structures, where ythe free space in which thegtoggle has to turn or swing is too limited for the ordinary gravity toggle which has to be of unnecessary length to obtain the overbalancing feature.

In my invention the toggle head is4 rigid andpreferably formed of `one pieceof sheet metal, which gives the maximum strength in spanning the opening in the Wall.

In the illustrative embodiment of myinventioii shown in the drawing the toggle head 1, Fig. 5 is provided with two flanges, 2 and 3 at preferably right angles to the base 4. Iii the flange 3 a hole 5iss truclr out and in the flange 2 a slot 6 having a curved portion 7 at its lowerend' is struck out or otherwise formed. The pivoting nut 8 is readily locatedfin the Atoggle head1 by inserting one of its trunnions `9 in the hole 5 and permitting the other trunnion 9 to drop into the slot y6. While this is an easy way of locating the nut in the toggle head, this connection would not be stable or permanent for the slightest jarring would cause the trunnioii in the slot; 6 to fall out, which would then permit the other trunnion v9 to become disengaged from the hole 5. To iiisure the nutA 8 being securely held Within the toggle head 1, I close theslot .6 by some suitable means. This closing-means has also an additional function, that of assisting in rocking the toggle head 1 with relation to the bolt 10. Y

I preferably employ a spring closing means and preferably a coil spring 11, having an arm 12 and an arm 13. The coil spring 11 is secured to the toggle head 1 in any suitable manner such as `by bending down

fingers

14, 14 from the base 4 of the toggle head. The arm 12 is secured to the toggle head inany suitable manner, such as striking up a finger 15 from the flange 3. The other armf13 of the spring 11 extends substantially parallel with the base 4 and over one of the flat trunnions 9, or similar surface, of the nut 8, closing the slot 6.

It will be clear from Fig. 6 if the end 1G of the toggle head 1 is bent down by the thumb, so that it is brought in contact with the stove lbolt 10,`that'the arm'13 of the spring 11 will be put under tension. As soon as the pressure of holding the end 16 in contact with the stove bolt 10 is released, the resiliency of the spring 11 will cause the toggle head 1 to assume the position shown in Fig. 6.

Preferably, though not necessarily, I extend the arm 13 to form an extension 17, Figs. 1, 2, 3, and 4. In this preferred construction the stove bolt 10 is 'passed through the work 18, to be supported on the face 19 of the wall or other suitable support 20, and is thenthreaded into the nut 8. By then bringing the end 16 into alinement with the stove bolt 10 the toggle bolt 1 is forced into the hole 21 of the wall or support 2O which will cause the extension 17 of the arm 13 to engage with the stove bolt 10 and put the spring 11 under greater' tension than if the arm 13 simplybore upon one of the trunnions. As soon as the end 16 escapes the rear face 22 of the Wall or support 2O the spring 11 will immediately cause the head to fly with a quick sharp snap into the position shown'i'n Figs. 3 and 1, the latter ligure showing my spring toggle holding the Work 18 firmly against the face 19 of the wall or other suitable support 20.`

My toggle bolt will work satisfactorily without the bent extension 17 on the arm 13, this 'latter construction being shown in Fig. 6. previously described. But with the extension 17 Y engaging withV the stove Abolt 10 greater tension is exerted upon the spring 11 which insures a quicker and snappier action as soon as the toggle head reaches the inner surface of the wall or other suitable support 2O.`

` Hav-ingthus described' this invention in connection with an illustrative embodiment thereof, tothe details of which Il do not vdesire to Ybe limited, what is claimed as new and what is desiredv to secure by Letters Patent is set forth in the appended claims.
