7 Application filed Toallwho mttmayconcem.

Be it known that I, MAUI D. L. MARTIN, a cit zen of the United States; and a resident of Houston, in the 'county of Harris and State of Texas,' have invented anew and Improved Bed stead Lock or Joint, of which the following is a full, clear, and exact de-' son tion. v I

- is inventionrelates to bedsteads, and particularly to a construction of the lock or {,(mt whic connectsvthe side rails of the dstead with the head and foot thereof.

The object of the invention is to produce a lock or joint of simple construction which will afi'ord meansfor securing the side rails rigidly and a reversible manner; and further, to provide such a construction which will relieve the fastening bolts'ofshea'ring strain. a

The invention consistsin the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims. 1 Reference is to be had to thefaccompanying drawings formin at art fication' in which arv&aracters of reference indicate corresponding parts in all .the figures. H p

Figure 1 is a perspective showing a lock to m'yinvention, together with the contiguous parts; Fig. 2 is a' plan and partial section further illustrating the construction-of-this lock;

Fig. 3 is a vertical section through the lock, taken on the line t -3 of Fi 2; and Fig. 4 is' a-vertical cross section rough the side rail, looking toward the lock' and'showing the rail in a reversed position; 5

Referring more 1 represents one o the corner, oats. of the bedstead, either at the head br oot thereof. On this post there is rigidly secured in any suitable manner, a bracket 2; t bracket has a horizontally projecting neck which is cutaway on one side so as to form an-angular or square socket 4, presentm a lonitudinal side face and an end face. and a horizontal shoulder or seat 6 on the under side. The depth of this socket is substantially the same as that of the neck 3. In the neck 3 and at the socket 4,.a bolt 7 is provided, having a square shank 8 seating in a square opening in the neck, which prevents the bolt from rotating. The e\'trem1ty of this bolt is threaded so as to receive a wing not 9, as indicated. The side rail 10 of the soc et. 4 as indicated of this speci-' particularly to the parts,

bedstead may be in Ltlie "of anlangle iron as shown. At the end of this rail an enlargement or head 11 {sameness any'- suitable manner.- This'ihea'd is of massive form andjtapers slightly toward the bracket 2. It presents two vertical shoulders 12,

between which there isfornied'a: cent-rally dis osed tongue 13 wliicliis' received inthe Th l m ts nd lower edges of this tongue-13 areformedwith slots 14 which are disposed 'o" posits to each other asindicated. Illese sl dts are in alinement with the bolt 7.. i

In setting up the bedstead the wing nut 9 is loosened on the bolt' 7, andthe tongue 13 is lowered down into theflso'cket so that the slots 14 on the lower-side thereof will enga e and receive the bolt. In this we -un er ed e of the tongue 13 seats itse f on.

the shou der or .seat 6.; The end of the tongue 13c0mes against the shoulder-'5, and the shoulder 12 on the head 11 comes against the end of the neck 3; The side of the tongue comes against the side of the socket. Un er the vfiing nut9, a washer 15'-of'suitup lied; and aftertlie'parts have been brou t' to ether as shown, the wingnut 9 is tig tenetfup. This ri 'dly secu'res the head to theb'racket' At e same time the entire weight supgortedby the side able form id "rail 10 is received on the s milder or seat 6.

In this way the bolt 7 isrelieved of all shearing strain. The nut' {simply operates to Prevent the head -11 roln' dis-. od ged from the Bracket and at the same time securelyholds the tongue 13 to the rackll. On account of the double arrangement of the slots. 14 it is possible to attac 1 rail in a reversed osition. In this connection attention is led to Fig. 4 and to the fact that the tongu'e'18 -is" in a central position, so that when the side rail is reversed as shown, the end of the neck 3 comes against the opposite shoulder 12.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent,-

1. In a bedstead lock,'a bracket havinfg a socket formed therein resenting a side are and a supporting shou der projccting therefrom, a transverse bolt mounted m said bracket and passing through said side face and through said socket, and a side bar having a head with a tongue projecting therefrom, the lower edge whereof seats on said the side a the shoulder, said tongue having a slot in the edge thereof receiving sa d bolt, and having a side face received against the said side face of said socket. v

2. In a bedstead, a bracket secured to the. bed-post, resentin a socket in the side thereof, said socket aving a face extending longitudinally and a supporting seat. a side.

bar. having a head with a tongue received in ing a socket on the side face thereof presentinga supporting seat. a bolt passing horizontally through said socket and mounted in said bracket, a side bar having a head with a centrally disposed tongue, and shoulders at the sides of said tongue at the root thereof. said tongue having slots in the upper and lower edges thereof either of which may receive said bolt in applying said head to said bracket.

In testimon} whereof I have signed my name to this pecification in the presence of two subscribing witnesses.
