BOLT

Filed Aug. 15, 1930 INVEN TOR.

' ATTORNEY.

jL/II. Twedell/ Patented a. 13, 1931 ATENT @FFEQE BOLT Applicationfiled August 13, 1930. Serial No. 475,048.

This invention relates to a bolt particularly adapted for use in holding siding and floor- I ing in place in railroad cars, warehouses, and

the like, and has for its primary object to 1! provide in a manner as hereinafter set forth,

a bolt for such purposes in which the bolt head is adapted to set flush with the siding or flooring in order that no obstruction Wlll be presented thereby to interfere with the moving of stored articles. 7

A further object of the invention is to provide a bolt having a head adapted to set flush as aforesaid, wherein the head is entirely free of rough surfaces in order that commodities 15,' contained in sacks may be moved across the bolt head in contact therewith without any probability ofthe sacks becoming torn.

A further object of the invention is to provide a bolt having a head adapted to set flush as aforesaid, wherein the head is provided with an inwardly inclined, annular skirt by means of which the point of entrance of the bolt is rendered fluid tight.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be under:

stood that the description and drawings are to be taken as illustrative, and that the invention is intended to be limited only by the scope of the claim hereunto appended.

In the accompanying drawings in which like numerals are employed to designate like parts throughout the several views Figure 1 is an elevation of a bolt in accordance with this invention.

Figure 2 is a section taken on the line 22 of Figure 1. V

Figure 3 is an enlarged, sectional elevation of the'bol't.

- Referring to the drawings in detail, the numerals 1 and 2 respectively indicate generally the shank, and head of my improved bolt. The shank 1 includes an externally threaded, cylindrical portion '3 merging at one end into an anchoring portion 4 which is square in cross section, and the side faces 5 of which are flush with the peripheral face of the portion 3 centrally of such side faces, whereby the corners 6 of the portion 4 are projected radially from the longitudinal plane of the portion 3. Adj cent the corners 6, the portion 4: is formed wit inclined shoulders 7 which merge into the peripheral face of the portion 3.

The head 2 is integral with the anchor portion 4 of the shank and is formed with a concaved lower face 8 whereby an annular skirt 9 is provided which overlaps a portion of the shank in con centric, spaced relation thereto with the inner diameter of the skirt gradually increasing toward its free edge. The upper face 11 of the head is flat-with the exception of a marginal portion 12, such marginal 1 portion being rounded and merging with the skirt 9 at the upper edge of the latter. The outer diameter of the skirt 9 gradually decreases in an unbroken line from the marginal portion 12 toward the free edge of the skirt whereby the skirt gradually decreases in thickness and forms a relatively sharp edge 10 at the line of mergence between the inner and outer faces of the skirt, such edge 10 being disposed inwardly of the outer radial, extremity of the head with a plane surface extending therebetween.

In the use of the bolt. the head 2 is driven or drawn into the wood until'the face 11 is substantially flush therewith whereby the edge 10of the skirt is caused to bite into the wood in circumferential relation to the shank 1. Owing to the tapered construction of the skirt. the edge 10 thereof is disposed inwardly of the marginal portion 12 of the face 11.

and the peripheral face of the skirt is wedged against the wood with increasing force as the may be resorted to, so long as such changes fall within the scope of the invention as .de-

fined in the appended claims.

What I claim is In a bolt adapted to be countersunk in wood, a shank having a head formed integral therewith, said head having a concaved lower face providing a skirt overlapping a portion of the shank in concentric-,spaced relation thereto, said skirt having its outer face extending at an inward inclination and in an unbroken line from the upper face of the. head and merging into the inner face of the skirt whereby a relatively sharp edge is formed to enable the skirt to freely enter the wood and whereby the wood will be continuously compressed outwardly from said edge to the upper face of the head'without splintering the wood when the head is drawn into the wood to countersink the bolt. In testimony whereof, I aflix my signature hereto. L

EDWARD M. TWEDELL.
