BED RAIL PIN Filed May 24, 1945 Patented Oct. 5, 1948 UNITED ST PATENT OFFICE Application May 24, 1945, Serial No. 595,643

1 Claim.

This invention relates to bed rail pins for mounting in bed posts and for securing the rail hooks in the rails.

An object of this invention is to provide a pin of this type which includes a smooth shank and a fluted or ribbed head which is adapted to be embedded in the wooden post or rail.

Another object of this invention is to provide a pin of this type which can be driven or otherwise forced into a hole formed in the wood, the pin having a fluted or ribbed head which will cut its way through the hole and will firmly hold the pin across the hook slot.

A further object of this invention is to provide a pin of this type wherein the flutings or ribs on the head may be either straight or spiral, and the head being adapted to be positioned flush with the outer end of the hole.

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a detail side elevation of a pin constructed according to an embodiment of this invention mounted in a bed post, the latter being shown in section,

Figure 2 is a transverse sectional view through the head of the pin,

Figure 3 is a detail side elevation of a modified form of this invention,

Figure 4 is an inner end elevation of the pin shown in Figure 3, and

Figure 5 is a detail side elevation of another modification of this invention.

Referring to the drawings, the numeral l0 designated generally a bed post or rail which is formed with a slot ll within which the rail supporting hook is adapted to engage. A pin generally designated as l2 is extended through an opening I3 which is formed in the post It] and the pin l2 extends across the slot II. The pin l2 includes a shank M which is formed with a bevelled inner end l5. A securing head I 6 is carried by the outer end of the shank I 4 and is formed of a plurality of spirally arranged fiutings or threads [1. The opening I3 is preferably of a size to receive the shank I 4 substantially friction tight and when the head I6 is moved inwardly of the opening l3, the pin will rotate and the threads or fiutings I! will cut their way into the wall of the opening and thereby firmly hold the pin in a horizontal position with the shank thereof intersecting the slot II.

In Figures 3 and 4, there is disclosed a modified form of this invention including a pin 12 having a smooth shank M which is bevelled as at 15* at the inner end thereof. A head I6 is carried by the outer end of the shank M and is formed with a plurality of flutings Il In the present instance the flutings l! are parallel with the length of the shank M Referring now to Figure 5 there is disclosed another modification of this invention embodying a pin I 2*, which has a tapered shank M The shank l4 has the larger end thereof innermost and the inner end of the shank M is a bevelled as at I5 The shank M has formed integral therewith a fluted head I6 embodying a plurality of straight flutings ll which are parallel with the longitudinal axis of the shank M".

In the use of this pin the pin has a length sufficient to provide for the shank I4 extending across the slot II and the outer end of the head I6 is adapted to be flush with the adjacent side of the post 10. The hole I 3 is drilled through one side of the post l0 and communicates with the slot II. The shank I4 is then moved into the opening I3, the bevelled end I 5 facilitating the positioning and movement of the pin shank through the opening. As the spiral head l6 engages in the opening l3 the pin will partially rotate, the fiutings l1 cutting their own threads into the wall of the opening and thereby firmly and tightly holding the pin with the shank thereof intersecting the slot 1 I.

Where a pin as shown in Figures 3 or 5 is used, the pin is inserted in the same manner but in these instances th pin does not rotate as it is forced into the opening. The pin may be inserted into the opening i 3 by any suitable means which will provide sufficient pressure to force the pin through the opening.

What I claim is: V

A bed rail pin comprisinga solid shank member having a smooth surface, a fluted head at one end of said shank, said shank being of a longitudinally tapered configuration converging at the adjacent end of said head, the root diameter of said fluted head being substantially equal to the diameter of the convergent end of said shank, and a bevelled edge on the opposite enlarged end of said shank.
