IMPROVEMENT IN BED-RAIL FASTENERS.

'lhe Schedule referred to in these Lettersl Patent nd'making part of the same.

To all 'whom it may concern.-

ee in known than I, JOHN.. LEMMAN, of oincmti, Hamilton county, State of Ohio, have inventeda certain new and useful Improvement in Fastenings for Bedstead-Rails; and I declare the following to he a sui'- ciently', full, clear, and exact description thereof to enable one skilled in the art to which my invention ap- -pertains to make and use it, reference being had 'to the accompanying drawing making part of this specication.

.Nature aml Objects of Intention.

My invention relates to the male part ot' bedi stead-fastenings, or that part .which carries the tenons and is permanently securedto the rail 5' and My invention consists in constructing the fastening of two pieces, with inclined shanks inserted in diagonal holes preparedin the rail, the pieces, when in place, locking together in such a manner'as to be capable of resist-ing any ordinary effort to draw them from therail, the object of myinven'tion being to produce what has not before been known, viz., a fastening for lhe rail of a bedstead which .can be secured to the rail without the aid of screws, glue, plates, or other device not formed in the casting itself.

Description of the Accompanying Drawing.

Figure 1 is a perspective view of the rail and fastening detached.

Figure 2 is a longitudinal section of the rail, with the fastening in place.

General Description. The rail A is provided with round holes, a a', bored diagonally, as shown, and a recess, I), of a width equal to the diameter of the holes. This 'work on the rail can'l be performed by a boring-machine, in which the rail is so secured and guided that the holes a a' Awill be the same distance apart in every rail, and at.the

same angle. The recess b is routed out in the act of moving the rail in the machine from one hole to` the other. g

'B B' represent the combined fastening.

Each piece is composed oi' body c, diagonal shank al, and customary T- shaped tenen e,the`latter for insertion into the female fastening'in the bed-post. The ends of the bodies c which meet together arebeveled or chamfered for a considerabledistance, as shown,

the balance being square, or at right angles with the bodies. The bevelin g is provided to enable the pieces,

when driven into the rail, to force each other apart, so as to tighten them in the-holes.

Then the pieces are driven fhome the square faces are brought together, and vserve to lock the pieces, so that they cannot be .withdrawn from the In cases of imperfect workmanship, resulting in loose lits, a screw may be inserted int-o the rail A, between the pieces B B', notches f being provided for that purpose, or a wedge maybe driven in between the pieces vfor the `same purpose.

` Claim.

rlhe fastenings B B', each provided with a diagonal shank, (l, and adapted, when in place in av bedsteadrail, to lock together, as and for the purpose described.

In testimony of which invention l hereunto set my hand.'
