CORNER LOCK Application filed December 70 all whom it may concern:
Be it known that I, HENRY RICHARDSON, a subject of the King of Great Britain, re siding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corner Looks for Bedsteads, of which the following is a specification.
This invention pertains to improvements in what are commonly known as corner locks for bedsteads, including the instrumentalities by which the side or end rails. or both, of a bedstead frame are separably united to the corner posts of the latter.
One object of the present invention is to provide an improved corner post bracket preferably of a generally box-like form to receive the end of the side rail or an attachment thereto, which bracket is preferably made of sheet-metal and is characterized by lightness, strength, simplicity and durability for cooperation with side rail fastening and locking devices. Another important object of the invention is to provide a simple means for strongly and rigidly' locking the side or end rails or both to the corner post bracket and which will securely hold the side rail in the bracket under the weight carried by the bed frame and against longitudinal pulling strains. A still further object of the invention is to provide an improved construction of corner bracket and locking means that will permitthe side rails to be inverted so as to support either a bed spring frame or slats.
Other objects and attendant advantages of the invention will be apparent to persons skilled in the art as the same becomes better understood byreference to the following detailed description, taken in connection with the accompanying drawings, wherein T have illustrated several specific forms or embodiments of the principle of the invention, and in which 7 Fig. 1 is a plan view of a sheet-metal blank from which my improved corner bracket is formed;

In the accomplishment of these objects, as disclosed by the drawings and as hereinafter described, :the bracketand side rail are held against relative longitudinal. and relative lateral movement'by means including a vertically disposed rail locking element :herein shown as a hug projecting from one of the said parts embraced by a co-operating rail locking element on the other Off said parts, said means actingjointly with rail locking devices ona side plate ot the bracketand a vertical limb ot the side rail to hold the said bracket and side rail against relative ang;ulaxr movement in a, vertical plane said devices. as herein shown, comprising a laterally disposed pin on one ot the said parts i-ntertittino' with a vertically disposed slot. in the other of said parts.
Reterrinp; .to the form of the invention illustrated in Figs. 1 to 7 inclusive, Fig. 1 shows a sheet-metal blank cut to provide outer and inner side walls 1 and 2 that are bent downwardly on the dotted lines a. 7)., a top or shel't plate 3" and a pair of rear wall members 4 and 5 that are bent inwardly oni'the dotted lines P. Z into overlapped relationand are rigidly attached to the bed post 6 by bolts or studs 7. From the inner side plateilthere is cut and bent upwardly on the dotted line 0 a horizontal attachment lug); l 'QWCljiETOHTlllP same side plate there is cut and'bent outwardly on the dotted line f a vertical attachment lug; 9. To the lugs 8 and 9 areriveted the horizontal and vertical limbs m an angle end rail 10 oi the bed -Frame. This end rail is provided with a lo Q'itudinal slot ll in its horizontal limb (Figs 3 andfi) tor a purpose hereinatter shown. In the top or shclt plate 3 there is also cut a slot 12.
13 designates an angle side rail. the end otxwhich may be reduced in \vidtln as shown in to fit within the corner bracket. In thehorizontallimb of the end or the side rail is cut a slot 14 (Fig. which. when the rail is fully entered in the bracket. registers with. the slot ;1 Through the registering" slots :12 and 14 spassed a keeper lugg- 15 oil the general U-formillustrated in detail in.
7 The curved lower portion of the '5 is preferably tapered from edge to er and when the lug is in place, it is engaged by a wedge-shaped key 16., best shown in 3, said key being provided with a stem or shank 17 extending beneath the hori zontal linibo't the end rail 10 and slid-ably secured to the latter by a stud 18 mounted therein and slidable through the slot ll when the wedge 16 is torced inwardly or drawn outwardly by a thumb piece 19 on the outer end ot its stem. The side limbs of the keeper lug; 15 have heads 15 which rest on the top plate 3 oi the bracket, straddling the slot 12. By means ot this device the side rail is strongly and securely locked to the top plate ot the bracket in such a manner as to trans mit all vertical strain to the latter and through the fastening studs 7. to the bed post.
In the outer side wall 1 of the bracket is secured a headed stud 20. This stud. when the side rail is fully entered into the bracket. is engaged with the bottom of a vertical notch 21. cut in the end ox the vertical limb of the side rail 13. The notch 21 is termed with a horizontal entrance way or slot 22. As the rail is passed into the brackeh the stud 20 passes through the entrance slot and as the rail is then raised to bring its top surface againstthe top or shelt plate ot the ln'acket, the stud 20 reaches its final position at the bottom of the notch 21, and, of course. a't'ter the locking key 16 has been applied. the stud 9 0 is locked in the bottom of the notch 21 against any possibility of displacement except by first withdrawing; the key 16.
The stnd 20 cooperating with the notch 21 effectively prevents any angular or tilting! movement of the post and bracket rela ivelv to the side rail in a vert cal plane tor the reason that such angular or tilting in ovemont. under the strains tendiiiig to cause the same. involves a relative upward movement ot the side rail and downward move ment of the bracket. and the engagement ot the stud with the bottom of the notch mak s this impossible when the looking key '16 is in place.
In the form of the invention illustrated in Figs. 8 to 12 inclusive, the same form and structure of box bracket as that already decribed is employed. Also the same attaching means for the end rail, and the same hip; and key means for locking the side rail to the top plate of the bracket. These parts aretheretore indentilied by the same reterence numerals heretofore employed to desi nate them and need not be again described.
Referring; first to Fig. to each end of the side rail 13 is strongly riveted an e);- tension member designated as an entirety by 30. This extension member is of general rectangular form comprising-an outer side wall 31, a top wall 32, a bottom wall 33 and a pair of inwardly extending lugs or cars 34' and 35 integral with the inner edges of the top and bottom walls 32 and 33. The top and bottom walls 32 and 33 are formed with key slots 36 and 37 corresponding functionally with the key slot 14 of Fig. 5, and the outer side wall 31 is provided with opposed vertical notches 38 and 39 and a common eutrance way or slot 40 that corresponds functionally with the notch 21 and entrance slot 22, of Fig. 5. Between the lugs 34 and 35 is an entrance way or slot 41 that corresponds with the slot 40 on the other side. This structure is designed to enable the side rail to be engaged with the corner bracket in either the upright or inverted position. By upright position is understood the position illustrated in Figs. 8, 9 and 10 wherein. the horizontal flange of the side rail is uppermost and adapted to support a bed spring'frame; while by inverted position is understood the position illustrated in Fig. 11 wherein the horizontal limb of the side rail is lowermost and is adapted to support cross slats. Secured in and extending crosswise between the outer and inner side walls of the bracket is a stud or pin 42. As the side rail extension is moved endwise into the bracket, the stud 42 passes through the entrance slots 40 and 41, andas the rail is then raised and locked to the top plate of the bracket, the stud comes to rest in the bottom of one of the notches 38, 39 and directly behind the corresponding lug 35, 34, according to whether the rail is placed in upright or inverted position. This construction not only permits the application of the rail in either upright or inverted position. but by reason of the double engagement of the rail extension with both side walls of the bracket through the pin or stud 42 it affords great strength and resistance to angular bending strains hereinbefore referred to.
Figs. 13 to 17 inclusive illustrate further modifications in both the top and side looking devices which may be employed within the scope of the invention. Referring to the top locking device, instead of slotting the top plate of the bracket for the passage of the keeper lug, the same is provided with a pair of holes 50, and the upper ends of the limbs of the keeper lug 15 (Fig. 17) are provided with tenons 51 which pass upward ly through the holes 50 and at their upper ends are riveted over the top plate of the bracket, as indicated at 52. By this construction the keeper lug is permanently secured to-the bracket plate, and the latter is not weakened by the cutting of a slot therein sufficiently large to admit the passage of the keeper lug.
The side locking devices embody the same principle as the corresponding device's already described, but in this case the bracket extension des gnated as an entirety y (Fig. 16) has the same top, bottom. I
and outer side walls as the bracket extension shown in Fig. 12 and is also formed with an inner side wall 54 which, however, does not extend to the outer end of the structure in order to leave an opening for the passage of the main locking key 16. The side walls of the bracket are formed with vertical notches 55, and the side walls of the bracket extension carry headed studs that engage with the'notches said studs 56 being located at mid-height of the bracket extension 53. The side rail extension is engaged with the bracket by entering it at a level at which the studs 56 clear the lower edges of the side plates in advance of the notches 55, and then raising it to permanent position in which the studs lie in the upper or closed ends of the notches, This, it will be observed, is a simple reversal of the stud and notch arrangement previously described, but. secures the same result of resisting relative angu lar displacement in a vertical plane of the side rail and bracket, since the tendency of the bracket to swing downwardly relatively to the studs, or of the studs to swing up,-
wardly relatively to the bracket. is opposed by the engagement of the studs with the closed ends of the notches. This structure, like that shown in Figs. 8 to 10 inclusive, allows the side rail to be postioned. in either upright or inverted form. In this construe tion I have shown the bracket applied to a corner post 6 of square form in cross-sec-- tion, but, of course, the form of the post is immaterial since the back wall of the bracket will be shaped to conform tothe surface formation of the attached.
Figs. 18 to 21, inclusive, illustrate a modi post to which it is I of the bracket are equipped. slightly below the top plate with studs 60 and 61. The side rail extension 62 (Fig. 21) is formed with four transverse corner slots, namely, upper and lower slots 63 and 64 on its outer side and similar upper and lower slots 65 and 66 on itsinner side. In this construction the side rail extension is engaged with the bracket by entering the same at a sufliciently low level to enable the top wall of the bracket extension to slide be-' neath the studs 60, 6] until the latter reg ister with the slots 63 65 or 66, 64 (accordingly as the rail. is applied in upright or inverted posit-ion) and then raising the rail and thereby carrying the studs 60. 61 to their seats in the bottoms of the side wall portions of the notches. Here again, any tendency to relative angular movement of the siderail and bracket in a vertical plane is Strongly opp by the engagement of the studs )ottoms of the notches.
Fiince the l attachment members herein shown are v e div and permanently fastened to the si e rail proper and constitute in eil ect end portions of the latter, it is to be under, oo-i'l that wherever the ends or end portions oi the side rails are rered to in th s specification or in the claims, I have Vacant to designate either integral cnd portioi or attached end portions, ot the side 1'? 'lll e term side rail d herei l llltt ided to include either i rail of a bed frame or the side rail of a bed-spring frame.
it is believed that the foregoing description in ci'innection with the drawings will .i' to those skilled in the art the novel structural teatures ot the present in ention and the principle underlying the same, vManileslly the forms shown and described by no means exhaust the struc tural variations and modifications that are possible within tie principle of the invention, but they are believed to be sufficient to make clear the structural and functional advantages which inhere therein. Hence, 1 do not limit the invention to the specific terms, arrangements and proportions shown in the drawings, but reserve all such variations and modifications as fall. within the spirit and purview of the appended claims.
