Description

' waited tatc @wat @like ALFREDB. SHEAFFER, OF EPHRATA, PENNSYLVANIA.
Letters Patent No. 103,511, dated May 24, 1870.
The Schedule referred to in these Letters Patent and making parl: of the same.
' wedge and screw for bolting the rails and end pieces firmly together, and so as to enable the wood'to be dra-wn as tightly together as at first, incase of shrinking in the wood so as to become loose.
The drawings illust-rate the construction and application of my invention.
Figure 1 shows an ordinary common bedstead with the wedges shown.
Figure 2 shows the three parts detached from the rail, but combined in relation to each other.
- Figure 3 simply shows the slotted screw-socket plug, with the headed screw-bolt withdrawn.
' Abrief explanation will enable anyone skilled in the business to make and'apply my invention. v
Combined, the three parts form a new article for the trade, which simply consists of an ordinary smoothheaded bolt A B, with a screw end, C.
The slotted screw-socket D has a female screwthread in one end for the reception of the screw end C of the bolt B. Both, united, are thrust through the post of the bedstead into the rail, so that the slot d in the plug D may receivea vertical wedge, E, (fig. 2,) ii'om the top of the rail, so as to project beneath, it' desirable.; the hole being bored horizontally for the adj nstable slotted plug D, and mortise' made vertically in the rail for the wedge E at the proper point, so as to set firmly in the wood, and draw upon the plug, to bring the rail and post squarely together, will form a firm and durable holder. It is only necessary to give the wedge a tap beneath, when it is easily withdrawn,
.and the parts separated without the use of' a screwdriver.
Should it be desirable to shorten the bolt to tighten the union of wood, in case of having shrunk in, it is easily done; the key or wedge E, in the slotted' plugnut, can be used as a wrench. Thus the steads can be tightened from time to time, and always held tirmly together.
I am aware that a removable nut with a screwthread is claimed, when used in connection with a certain cross-piece; as also nuts made in screw-plugs, that can be inserted direct into an anger-hole, and drawn by a screw-driver; as also an appended wrench, nut, and hook combined,I and the like, which I do not claim.
What I claim as a new combined bedstead-fastcning, as a new article for the trade, is-
The combination andarrangement of theplng D, with its slot d, and screw-socket for headed screwbolt A B G, with the wedge E, all operating in the. manner and for the purpose specified.
lALFRED B. SHEAFFER.
