` BEDSTEAD-FASTEN ING.

`Specication of Letters Patent No. 3,387, dated December 20, 1843.

To all 'whom t may concern Be it known that I, JOSEPH GUILD, of the cityof Cincinnati, county ofHamilton, and State of Ohio, have invented a new and useful Improvement in the method of fastening and connecting the rails of bedsteads with the posts by means of cast-iron fastenings made on the principle of the screw or inclined plane; and I do hereby declare that the following-lis a full,jclear, and exact description ofthe construction and operation of the same, reference being had to theanneXed drawing, making apartof the specification.

Figure l, represents Va sectional `view of the same. Fig. 2, shows the method of fas-` tening thepiron in the posts and rails. Fig. 3, is an end viewlofthe fastenings.

F ig. 1, letter a, shows thefca-st iron cylinder one and three quarters ofvan inch in `diameter by the same in depth made open Von the back end that goes into the post and having an opening in the front end in the shape of a key hole as shown in Fig. 3, letter 0. This is let into the post by boring a hole of the saine ldiameter. as the cylinder" and driving the saine in until it is flush with the post and iron pin, is then driven in the hole in the sideot the cylinder shown in F ig. l, letter CZ', by boring a hole the size of the pin in the post opposite the same as shown in Fig. `2, let-ter CZ, where the dotted linesgshow the pin.

ZJ, b, Fig. l, are inclined planes cast on the inside of the outer end of the cylinder forming the screw; into this the shank, Fig. l, letter e, is inserted by means of the opening before described and the dogs cast on the end of the shank by being'turned partly around take hold of the inside of the cylinder on the inclined plane and screw up the rail firmly to the post. On` the shari'k Fig. l are dogs cast on the sides as shown by the letters g, g; these are about halt an inch wide by three eighths of an inch thick and are intended to prevent the shank from turning in the rail in screwing it up; there is likewise a pin passing through the shank, as shown at Fig. l, letter 7i.

The parts being fastened as above de` scribed by the iron Shanks being put into t-he ends of the rails and the iron cylinders fixed in the posts as before described the end of the rail which will fit either of the cylinders in the posts is entered therein at the opening c and by turning the rail partly around with a wi'enchniade to t the same it is firmly screwed up to a'joint` to the posts at each end. The other rails are then introduced inthe saine manner into the screwed up. That I 4claim as my invention is- The `cast iron cylinder introduced into the bed post and fastened with the pin in the manner described.
