Description

H. G. REINIGER.

SCREW.

APPLICATION FILED SEPT. 16, 1910.

Patented Feb. 21, 1911.

- E STAWENT OFFICE- HENRY e. REINIGER, or RATHDRUM, IDAHO.

- SCREW.

To all whom it may concern.'.

Be it known that I, HENRY G. REINIGER, a citizen of the United States, residing .at Itathdrum, in the county of Kootenai and State of Idaho have invented certain new and useful Improvements in Screws, of which the following is a specification.

The invention re ates to improvements in screws such as are employed. in fastening together stove-pipe sections.

It has for its object the provision of a device that can be easily applied and removed and which, when in place, will be secure against accidental displacement.

It consists of a screwof the novel construction hereinafter described, pointed out in the appended claims, and illustrated in the accompanying drawings.

In the accompanying drawings, in which similar reference characters designate corresponding parts, Figure 1 is a side elevation of a screw embodyingthe invention. Fig. 2 shows the screw applled to a -joint. I

The shank a of the screw tapers toward its point 5, and is-provided with a thread 0 square in cross-section. The outer -extremity d of the thread ends a short distance from the point b, and the inner e'xtremity e ends at the shoulder f of the shank a short .distance from the head 9 of the screw. The head 9 is of the usual formation except that it'has 'a beveled inner face h.

Between the heady .and the shoulder f is the neck a of reduced diameter, the latter gemngxlees than the diameter of the threaded In applying the screw the end of one pi e-- section 1s inserted in the end of anot er so thattheir edges overlap, and by means of asultable implement coincident holes are punched through the metal. of the overlapplng edges. The coincidentholes should be of less diameter than thethreaded shank,

but sufiicie'ntly large to admit the point" I). After the holes have beenformed the point 5 is inserted and the shank forced: in until the outer extremity d of the thread engages the-' edges of the metal of the overlapping pipesections. Then by means of a screw-driver the screw is turned through-the coincident holes until theedges 'of the metal clear the shoulder f and spring around the reduced .neck 5.

As the neck 71 has less diameter than the threaded shank and as the metal around the holes has contracted, the screw -cannot be shaken loose or otherwise accidentally displaced.

To remove the screw, a flat .implement such as a screw-driver is inserted between the beveled face h of the head and the pipesection to slightly force outwardly the screw so that the extremity e of the thread will engage the edge of the metal. At the .same

; time by means of a screw-driver the screw is turned until the thread engages the metal of the pipe and the screw is turned out of the, coincident openings. As soon as the ex- Specification of Letters Patent. Patented Feb. 21, 1911. Application filedSeptemher 16, 1910. I Serial No. 582,357.

tremity e engages the edge of the metal of the pipe the blade can be removed from beneath the head of the screw.

Having thus described my invention, what I claim and .desire to secure by Letters-Patent is,

1. A screw comprising a head, a pointed shank, a thread extending along the shank with its extremities ending short distances from the head and pointed end respectively, and a neck between the inner extremityof the thread and the head, said neck being of less diameter than the threaded shank.-

2. A screwcomprising a head with a-bev-- eled inner face, a pointed shank having a shoulder near its inner end a short distance from the head, aneck of reduced diameter betweenthe shoulder and head, and a thread shank.

In testimony whereof I hereunto aflix my Witnesses:
