GALMAN XVOLF, OF ROCHESTER, NEV YORK.
IMPROVEMENT IN BEDSTEAD-FASTENINGS.
Specification forming-part of'Letters Patent No. 142,973, dated September 16, 1873; applic-ation filed 'June 20, 1873.
To all whom it may concern.:
Be it known that I, GALMAN WOLF, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain `new and useful Improvement in Bedstead-y Fasteuings; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the saine.
My improvement belongs to that class in which a iianged Wedge is used, resting against the stop, and serving to draw out or tighten the hook upon the pin. As previously constructed, such Wedges are liable to draw away or disengage from j the hook, owing-to the shape ortho form of the tongue-andgroovc connection between them.
My invention is intended to obviate this di'l'tlcnlty; and consists in the peculiar form of the wedge and its anges, as hereinafter described, whereby this result is attained. It also consists in the combination, with the wedge and hook, of a spring for rctracting or throwing ont the hook when' the wedge is raised.
lfn the drawings, Figure lisa side elevationV of my improvement applied to a bedstead; Fig. 2, a crosssection of -the same; Figs. 3 and 4, modilied forms.
.A represents the post, and B the rail, of a hedstead. C is the hook, which engages with the. cross-pin c in the ordinary manner to lock ihe rail and post together.. The shank of the hook extends through the stop or cleat G, and has a socket, t, through which -passes the wedge D, ly which the tightening action is produced. The Wedge and socket are of pe onlinr forni. The wedge is 'preferably pro vided with two right-angled iiangcs, c and d, prfgecting freni thc opposite faces, shown in' Figs. 3 and fl, thatnpon the outside engaging.,r with a slot, f, ibrinedin 'the socket et the hook, and that upon the inside running in. a slot, g, which is'cnt out ci the wood oi the rail. A blank, l1., is left atdhe top ni.' the ilange c, i'or the passage et' thc socket over or through it in engaging' the pa The inner edge of the iianfge c, and also th socket b, are made tiled, as shown :rt/i, so that when once ci ed the hooi; und. the vfcdge cannot be #Shielding-ui except by sliding' them apart, sov
that the sockethead passes over the Kblank h, This is an advantage, not only in holding the parts together in store, but also in holding` the hook in line in the drawing action of the wedge, and thereby preventing bindin g, strain, and denting of the Wood. The iiange d is shorter than the length of the Wedge, leaving blanks 7c 7c at each end. Its length is intended to be such as to play up and down in the slot g of the rail Withoutuneovering the slot at the .highest or lowest positiornso that no hugs can find an entrance.
It will be noticed that the inner edge of the v wedge is vertical, and moves up and down against the stop Gr, the dange d and slot g, also, being vertical for the purpose. The opposite edge of the Wedge and its liange c stands inclined, to produce thel necessary wedge action.
The advantages of this arrangement lie in the flanges c d ot' the Wedge standing at right angles thereto, and arranged with the blanks or spaces 7i L for the easy connection and truc working of the parts. An important feature consists in the dovetailed connection 0f the flange c and socket Z1, `and also in the short iiange (l, which forms a part of the square side bearing againstthe stop.
To produce a retraction of the hook when vthe Wedge releases it, a spring, E, Fig. 1, may be employed, screwed or otherwise attached to the edge oi' the stop G, and resting at its lower end against a shoulder, in, of the shank of the hook. The tension of the wedge bends the spring in\..'ard, as shown, and when relievcd the spring; throws thc hoolehead ontward, so as toho easily. i'rce of the pin c..
I'Vhcn this spring is employed the wedge may be niade'with the single flange d, as shown in- Y' Fig. 2, and the dovetail c' may beon the outer instead of the inner edge.
v Having thus described my invention, I do not cla-ilu, hroz'idiy, a Wedge for tightening the hook, ner do l claim a wedge havingr a flange on thc "hack side and a groove in the face,
'with a `rib ol' thc hooleshanlc runnin@ in it;
but Y What I claim as new is- Y l. in combination with the hook U ol' a bed-- stead fastening7 the wedge l), constructed with the Haugen 1 .Il upon the opposite hueca,
2 ,l i y jv4 A Mginanud with tho blanks h k la fof conneoting the parts, said flange c boing dovetaled to fit the socket; of tho hook-shank, and said flange d playing in n vertical slot ofthe bedsjead-ral,
:is shown and described, and for thepurposo specified. i 2. In combination with tho hook C and wedge l), the reacting spring E, engaging with shoulder, m, of the hook-shank, all constgructed, arranged, audpera'ting as slgown and des'cribed.
In witness whereof I have hereunto signet]t my name in the presence of two subscribing witnesses. i CALMAN WOLF.
