CORNER-LOCK FOR TAKE-DOWN FRAMES.
erases Locks for Take-Down Frames, of which the following is a specification.
-My lnvention relates to improvements 1n corner locks for take-down frames, and,
'although susceptible of various applications,
is of" particular service for use in connection with metal bedstead frames which, in the maf jority of cases, must be shipped or transported in a knock-down condition. Such bed stead frames usually comprise a head frame or end and a foot end, said ends being connected by means of detachable side bars eX- tending between the corner posts of the bedstead. In the drawings which accompany this` application I have disclosed a corner lock for providing the detachable connection betweenthe side rail of a bedstead and one of `the corner posts or pillars.
Among the principal objects of the invention are, to provide a corner lock of the class described, the separable parts of which may be constructed of tough material, such as sheet metal, thereby obviating the risk of breakage incident to the use of cast metal,
usually employed in such constructions; to provide a construction of the class described, so organized that certain parts may be de tached from the members to be connected so that the several parts of the frame shall occupy a minimum amount of shipping space; to provide a construction .in `which the parts of the lock may be applied or united to 'the frame members without damaging the 1.54; structure or injuring the surface finish of the frame; to provide a construction which admits of the convenient application thereto ci subsidiary tie or strut members for stiliening or strengthening the frame as a whole; to provide a constructiim of the class described in which the lock is effective independently of any reversal ofthe rail member; to provide a construction of the class described which shall be simple and economical to construct, while being eliicicnt to maintain and keep in repair" and in general, to provide an ini aroved cui truetion of the character referre to.
Fig. 3 is a plan view of the corner lock lshown in Fig. 1; V
Fig. 4: is a perspective view of the end of a reversible side rail equipped with the mating member designed to enter the socket member shown in Fig. 5, and
Fig. 5 is a perspective view' of the pillar socet constituting one portion of the corner loc l Referring to the drawings, represents a hollow steel post or tube, to the outer por tionvof which is conformed a portion of a sheet metal stamping 11 which is U-shaped in plan, the bridge or back piece 1Q of the U'engaging the wall of the post and` the arms or fianges 13 and 14 of the U being substantially vertical and parallel to each other. The U piece 11 is secured to the post by means of a bolt like member 15 inthe interior of the post having its threaded ends 16 projecting outwardly through the walls of said post. Preferably, a curved liner is inserted in the tube l0 having a pair of openings therein through which the ends 16 of the member 15 pass. Nuts are provided for the threaded ends for securely holding the U shaped member on the tube 10.
The tie rail 18, which connects the post 10 with its companion post at the same end of the bedstead, is permanently united to the housing or socket 11 by having the ends of the two flanges riveted on the outer face of the arm 13 of the U. Thisrail 18 has the p Specicaton of Letters Patent. Patented Sept, 17, 1918,
Application filed May 10, 1917. Serial No. 167,818.
outer edges of its two flanges cut away as at 'that which I'have just described.
The side rail 21 is a length of angle iron having a horizontal fiange 22 and a vertical flange 23. As shown best in Fig. 4 the end of the horizontal flange 22 is cut away slightly, asv at 24, in order to itwithin a stamping indicated generally at 25, The
.member is made up of a single piece of metal folded back upozritself and secured by lips or tongues 26, or it may be welded or secured in any desired manner. It has a channel shaped part 27 vformed from Athis blank 25 which projects forwardly therefrom, and is provided with outwardly facing edges of flanges'29 and 30 which are adapted to fit snugly within and between the y flanges 13 and 14 of' the socket 11. Said member 25 may be secured to the rail 21 by 'onaor more rivets 28, by spot welding,` or in itl any other approved manner.
ln order to lock the end of the rail in the socket 11, the vertical flanges 13 and 14 of the latte-r are eut out to form opposed slots 31 and `32 slightly inclined to the vertical,
the tops of the slots diverging outwardly from the post. Said slots are made of sufhcient Width to readily admit the projecting' ends 33 and 34 of the transverse horizontal n cylindrical pin 35 .securely seated in apertures drilled through the sides of the ineinber 25, and the vertical flange 23 of the side flange 22 of the side rail at the bottom instead of at the top of the flange 22.
llhen making such reversal,l it will of course be understood that the rail is turned end for end so that the edge of the flange 22 remainson the inside of the bedstead traine. This reversibility of the side rails in the sockets enables the same construction to be used for different types of bed springs.
ln view of the above description, nothing special need be said further about the functions of' the severalparts of the structure. lt will .be noted that the vertical edges 36 and 37 of the rail member are forced into the angles between the `flanges 13 and 1.1i' and the back piece r12 throughout their entire length, by reason of the Wedging action, due
to the inclination ot the slots 31 and 32. In this connection, vit should be understood that the ends of the pin 35 press outwardly against the outer edges of the said slots, Which thus constitute Wedging ab'utments opposite to the abutments formed by the angles at the roots of the danges i3 and i4.
By utilizing a pin tor-engaging the inclined abutment of the separable joint, .l ain not only enabled toproduee a reversible conH struction, but, in atddition thereto, the joint possesses great structural rigidity against transverse or twisting stresses. For instance, relative swinging movement of the rail about the axis of the )ost is positi ely prevented by reason of tlie fact that the edges 26 'and 27 are widely spaced apart on Larmes either side of the vertical anis of the joint, also swaying of the post is "minimized by reasonofthe fact that the pressure on each side of the vjointl is concentrated at three widely spaced points, viz., the pin, and the top' and bottom of the vertical abutting; edges of the members.
The described details of construction may be varied considerably without departing from the spirit of the invention, the scope ot which must be determined by reference to the appended claims.
