HENRY W. PLEISTER, E WESTFIELD, NEVJ JERSEY, ASSIGNOR TO HENRY W. NEW- HALL, 3B)., EXECUTOB OF HENRY W. NEW'HALL, DEGEASED.

SPRING-TOGGLE.

Specification of Letters Patent. Patented Apr. 19 1921 7 Application filed. December 23, 1919. Serial No. 347,044.

To all to 710m it may concern:

Be it known that I, HENRY W. lnnrsrnn, a citizen of the United States, residing at Westfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in sprmgfloggles, of which the following is a specification, taken in connection with the accompanying drawings. r

My invention relates to toggles. More particularly it relates to means which will insure that the toggle head Wlll rock or swing at an angle to the arm or bolt, after it has been inserted into the wall or other support.

My invention furtherrelates to a toggle ,having a head provided with pivoting means midway its length, so that one end 9 oes not overbalance the other, and means 10 insure the rocking of the toggle head when it has been inserted in the wall.

My invention further relates to a rigid toggle head which is swung upon the pivoting nut by a spring earned by the head. It further relates to such a toggle bolt in which the pivoting nut has'a fiat surface upon which contacts the spring carriedby the head. It further relates to such a spring toggle in which, preferably, eithenend of the toggle can be brought into alinement with the bolt to permit the toggle to be 1nserted into the hole in the wall or other suitable support.

My invention further relates to the spring, as a separate article of manufacture, which is bent into U shape to form a pocket to receive the nut, the ends of the spring being secured, in any suitable manner, to the head. 7

My invention further relates to certain combinations and details of construction which will 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 in the different figures. I

Figure 1 is a perspective view of my spring toggle bolt, one of the flanges be ng omitted from the toggle head for purposes of clearer illustration;

gravity toggle from operating.

Fig. 2 is a vertical section through a wall or other support and the work to be sup ported, showingthe manner of positioning the spring toggle, which is shownin side elevation;

Fig. 3 is vertical section through a wall or other support, andthe work supported, the same as in Fig. 2, but showing the toggle iead rocked at right angles to the bolt by means of the spring; f

Fig. 4 is a perspective view of the toggle head; and i Fig. 5 is a perspective view of the U shaped spring, which I preferably employ.

In the toggle bolts now on the market it is customary to pivot the armor bolt to-the head so that one end of the head is heavier than the other. That is, the pivot is not located substantially midway between the ends of the head. By having one end longer, that.v end will be heavier than the other end, and consequently will have a tendency to overbalance 1t and cause the toggle head, as soon as it is pushed home,

' By my invention I positively insure that.

the toggle head will assume a position at an angle to the hole, through whichit has been inserted, even though it should scrape upon some slight obstruction which would be sufficient to prevent the ordinary form of Further I can make my, toggle head of minimum length which will not only save metal, and

therefore-cost of manufacture, but it will permit my tog le to be used in thin partitions, or similar walls or structures, where the free space in which the toggle has to turn or swing istoo limited for theordinary gravity toggle which has to be of unnecessary length to obtain the overbalancing feature.

In my invention the toggle head is rigid and preferably formed of one piece of sheet metal, which gives the maximum strength in spanning the opening in the wall.

In the illustrative embodiment of my invention shown in the drawing the toggle head 1, Fig. 4, is preferably formed from stamped sheet metal and comprises a base 2 and flanges 3, 3. In the flanges 3, 3 I stamp out, or otherwise form, bearings 1, 1 for the reception of the trunnions a, of the*nut 6. These bearings are preferably situated midway between the ends 7 and 8 of the toggle head. In my invention I employ a spring, which is secured in any suitable manner to the toggle head and which rests upon the fiat surface of the nut 6. In my preferred construction I form a spring 9, Fig. 5, of bent wire, having the ends bent back upon itself to form a U shaped pocket 10 to receive the nut 6, the ends 11, 11 of the spring being extended and secured in any suitable manner to the toggle head 1, by the hooks 12, 12 being secured in the slot 13 in the base 2 of the toggle head.

In using my invention the bolt 14% is passed through the work 15 and is then threaded into the nut 6, first passing through the throat 16 of the pocket 10. As soon as the end 7 or 8, as the case may be, escapes the inner surface 19 of the wall or support 18, the spring 9 will then immediately throw the head 1 at right angles to the bolt 14, as shown in Fig. 3. By screwing up the bolt, the work 15, whatever it maybe, is then secured to the face 20 of the support 18.

Having thus described this invention in connection with an illustrative embodiment 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.

lVhat I claim is 1. In a toggle, the combination of a head,

a nut having a flat surface, and a spring bent back on itself to form a pocket, the nut being located in the pocket, and the spring being secured to the head bearing on the fiat surface of the nut and normally positioning the head at substantially 90 to the bolt.

2. In a toggle, the combination of a head, a nut having flat surface, and a spring bent back on itself to form a U shaped pocket, the nut being located in the U shaped pocket, and the spring being secured to the head bearing on the flat surface of the nut and normally positioning the head at substantially 90 to the bolt.

3. In a toggle, the combination of a head, a nut having a flat surface, a bolt, and a spring bearing on the flat surface of the nut and connected to the head permitting either end of the head to be brought into alinement with the bolt.

4-. A new article of manufacture for use with a toggle comprising a wire spring bent back on itself to form two arms, each of the arms being separated and bent back on itself to form a double U-shaped pocket with parallel sides to receive the nut of a toggle bolt, the two free ends of the wire spring being provided with means to en gage a toggle head.

HENRY W. PLEISTER. VVitness'es MAnrR. RYAN, A. M. WILLIAMS.
