UNITED STATES PATENT OFFICE.

JOHN H. STILLWAGGON, OF RICHMOND HILL, NEW YORK.

FASTENER.

Specification of Letters Patent.

Patented Apr. 4., 1911.

Application filed December 24, 1910. Serial No. 599,221.

To all whom it may concern:

Be it known that I, JOHN H. STILLWAG- son, a citizen of the United States, residing at Richmond Hill, in the. county of Queens and State of New York, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

.This invention relates to fasteners adapted to be used with hollow metal bodies inaccessible from the rear. Its novelty consists in the construction and adaptation of the parts, and it has for its object the production of a fastener which shall be both cheap to construct and efficient in use.

In the drawings, Figure 1 represents a portion of the front wall of a hollow metal body, for instance, a hollow metal partition inaccessible from the rear. Fig. 2 is a side elevation of a fastener embodying my in vention without an axial stub. Fig. 3 is a side elevation of the same with an axial stub. Fig. 4 is a perspective of the forms shown in Figs. 2 and 3. Figs. 1 and 4 are respectively detail views of the split spiral disk and the axial body. Fig. 5 is a sectional view through the wall and a side view of the form of fastener shown in Fig.

3 inserted therein with a depending bracket secured thereto by a nut. Fig. 6 is a detail of the nut shown in Fig. 5. Fig. 7 is a form of fastener embodying a bracket which is" also used as a rotating member. Fig. 8 is a section of the wall and a side View of the fastener shown in Fig. 7 inserted therein, the fastener being provided with an axial stub. Fig. 9 is a detail of a form of nut adapted to be used with the form of fastener shown in Figs. 2, 3 and 4 and provided with a ring or eye, and Fi 10 is a detail of a socket wrench adapte to be used with the form of fastener shown in Figs. 2,3 and 4, whereby the fastener may be rotated.

In the drawings 10 designates a wall ofa hollow article'inaccessible from the rear.

For use with my improved form of fastener edge of the slit 13 bent slightly inward to engage the split spiral disk of the fastener as hereinafter described. Or it may be furnished with, a key hole slot in which 14 represents the round hole and 15 the longitudinal slit with separated edges 16 and 17.

The fastener proper comprises an axial a projection 220 beyond the same (see Fig.

3). Where no means are otherwise provided for rotating the fastener it is preferably provlded with a polygonal tail 27 which may be engaged by a simple form of socket wrench illustrated in Fi 10 and provided with a socket 28 adapte to engage the polygonal tail 27.

The device as described is readily secured to the wall. The outermost leaf 26 of the fastener is inserted under the upturned edge 12 of the slit 11 and the fastener then bein rotated, the split spiral disk is thus forced from the outside to the inside of the wall 10 as shown in Fig. 5. It will be observed that the distance between the outermost leaf 25 of the spiral disk 24 and the inner shoulder 22 must be substantially equal to the thickness of the metal of which the wall 10 is composed or the fastener will not be tightly secured in position and will be more or less free to rotate which is undesirable.

fWhen the form of fastener shown in Fig.- 3 is used and it is provided with an inwardly extending'stub 220, the key slot must be made inthe wall. The stub 220 then en ages the round portion 14 of such slot and the fastener is thusregistered in position and its manipulation 1s slightly easier.

After the fastener isv in position a bracket member indicated at 30 may be slipped over the body 20 and held in osition by a nut 31 or an internally threa ed sleeve 32 having a depending ring. 33 mag be used, or a variety of simi ar holding evices may be employed all of which must of necessity be provided with means for engaging the body of the fastener. I ma ,however, make the fastener to comprise within itself both means. whereby it may be rotated to position and may be adapted to support articles as a bracket after such rotatlon. Such a device is shown in Figs. 7 and 8, in which 20 is the body having the stub 22 and disk 24 as before, but in which 200 is a bracket L'cessible from the rear comprising an axial member by means of which the device may readily be rotated.

What I claim as new is q I '1. A fastener adapted to be used in securing articles to a hollow metal wall inaccessible from the rear comprising an axial body, a split-spiral disk arranged substantially at a right angle thereto anda shoulder adapted to contact with the outer surface of the metal wall when the fastener. is in place. a a 2. A fastener adapted to beused in securing "articles to a hollow metalwall inaccessible from the rear comprising anaxial body, a split spiral disk arranged substantially at aright angle thereto, a stub arranged forward of the disk, and a shoulder adapted to contact with the outer surface of the metal wall when thefastener is in place:

3. A fastener adapted'to be used. insecuring articles to a hollow metal wall inacbody, a split spiral disk arranged substantially ata right angle thereto and a'shoulder arranged at a distance from the rear of the stud substantially equal tothe width of the metal plate into which the fastener is .to be inserted.

4. The combination with a hollow metal article inaccessible from the rear and provided with a slit in its front face, of a fastener comprising an axial body, a split spiral disk mountedthereon and adapted to engage the said slit, and a shoulder adapted to contact with the frontface of the metal article after the fastener is inserted.

5. The combination with a hollow metal article inaccessible from-the rear and provided with a slit in its front face, of a fastener comprising an axial body, a,split spiral disk mounted thereon and adapted to engage the said slit, and a shoulder adapted to contact with the front face of the metal article after the fastener is inserted ar-' ranged at a distance from 'the rear of the stud substantially equal to the width of the metal plate into which .the fastener is to be 7. The combination with a hollow metal article inaccessible from the rear and proyide'd with 'a key slot in its front face, -a split spiral disk mountedthereo/n and a stub forward of the disk adapted to be inserted in the round portion of the slot whereby when the fastener is rotated the split disk will engage the longitudinal portion of the slot and a shoulder adapted to contact with the front face of the metal article after the fastener is inserted.
