C. P. CAMPBELL LOCKING TONGUE FOR KNOGKDOWN FURNITURE and June 9, 1923 'INVENTOR CFC/QMPBCLL Z5 FIG-H.
Patented May 12, 1925.
UNITED STATES CHARLES PETER CAMPBELL, OF ORILLIA,.. ONTARIO, CANADA.
LOCKING TONGUE FOR; KNOCKDOWN FURNITURE.
Application filed June 9, 1923. Serial No. 644,410.
To all whom it may concern:
Be it known that I, CHARLES PETER CAMP- BELL, of the town of Orillia, in the county of Simcoe, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Looking Tongues for Knockdown Furniture, of which the following is the specification.
My invention relates to improvements in looking tongue construction for knock-down furniture, and the object of the invention is to devise a locking tongue and coac'ting parts which may be simply and cheaply constructed and yet be ei'iicient in operation, and it consists essentially of the arrange ment and construction of parts hereinafter more fully explained. f
Fig. 1 is a sectional view of twowall members set at right angles one to the other, and my locking tongue connection applied thereto.
Fig. 2 is a vertical section taken through Fig. 1, showing the locking tongue in full and the wall members in section.
Fig. 3 is a plan View of the blank out of which my locking tongue is formed.
Fig. 4 is a perspective View of the blank shown in Fig. 3 partially bent up to form a locking tongue. s
Fig. 5 is a perspective detail of the end cap forming the head of the locking tongue. Fig. 6 is a perspective view of a portion of the keeper bar showing one of the keepe slots therein.
Figs. 7 to 12 show a modified construction adapted to lock the walls of a drawer together.
Fig. 7 X is a plan View showing the parts illustrated in Figs. 7 and 8.
In the drawings like characters of refer ence indicate corresponding parts in each figure.
1 indicates a corner post of a piece of furniture. 3 indicates a side wall conuectedto the post 1, the vertical edge of the wall being secured in vertical grooves 4 formed in the post 1. The post 1 is recessed as indicated at 5.
7 is a wall which is to be detachably connected to the post 1. 8 is a channel bar provided with a slotted opening 9, the side edges of which converge downward. The lower portion of the slot 9 is provided with a slit extension 10.
11 is my locking tongue. Each locking tongue] is formed from a sheet metal blank, as illustrated in Fig. 3.
The body of the blank is in the form of a strip ofmetal, the ends of which are provided with out-turned portions 13 and 14,
the end edges of which incline downward in a converging direction when the blanks formed by the end portions 13 and 14 are turned outward, as illustrated in Fig. 4.
The body of the blank 12 is bent upon itself centrally as indicated at 15, and by the dotted line'15", Fig; 3. V The upper edge of the blank 12 isprovided with extensions 16 and 17, the inner ends of which are separated from each other by the slit opening 18 which is in vertical alignment with the dotted line 15*, (see Fig. When the blank 12 is formed into the locking tongue, the portions 16 and 17 are bent outward forming horizontal flanges as indicated in Fig. 4. When the portions 12 and 12 01' the blank 12 are bent'togetherinto a parallel position, the free ends of the blank formed by the out-turned portions 13 and 14 are secured together by means of the securing cap 21 forming a head, the con struction of which I will later describe.
Each corner of the wall 7 is provided with a' saw cut slit indicated a629," into which the locking tongue 11 fits. Although I 5 'have described the tongue 11 as secured in this way, it will of course be understood that it may be secured to the wall 7 in any other way desired.
When my device is appliedto a bureau so drawer, it is preferably constructed as follows-:
35 and 36 are two adjacent walls of a bureau drawer. The edge of the wall 35 is provided with a recess 38, and the adjacent wall with a recess 40.
42 is a channel piece secured in the recess 38 in proximity to the top and bottom wall. Each channel piece 42 is provided with a downwardly slit opening 44 having open 9 formed that when the portions of the body 110 The body of the locking tongue 45,
- will sli upward theme mo.
are bent together, the out-turned extensions 47 and 48 are'provided, (see Figs. '9 and 11).
The outer ends of the extensions 47 and 48 are constructed in asimilar manner to that illustrated in Figs. 5 and 6, thereby forming locking heads which engage in the channel portions 42 by slipping that portion of the tongue adjacent to the extensions 47 and 48 vertically downward into the slit openings 44, thereby securely holding the end Walls together.
I will now describe the construction of the cap 21 #by which the f-reeends of the portions 12" and 12 of the locl'r ing tongue 11 provided with the out-turned portions 13 and 14 are secured together, and also the corresponding portions of the locking tongue 45 provided with the out-turned portions '47 and 48. I
The front wall of the cap 21 is provided with downwardly inclined converging side edges corresponding to the inclined "edges 13 and 14 in one case, and the inclined edges "of the portions 47 and 48 in the other case. Each si'deed'ge *of the body of the cap 21 is provided with inturned portions 22 and .23
terminating in portions 24 and 25 turned inward at right angles to the portions 22 and so that when the portions 13 and 14 are brought together, the cap above described The front portion of the cap hears against the outer faces of the portions 13 and 14. The portions 24 and 25 b'e'a r against the inner face of the portions 1 3 and 14 in one case, and in the otherease against the outer face of the portions-457 :and 48, andthe portions corresponding tothe portions 24 an'd 25 against the inner face of the poi tions 4F and 48. To -secure the nap in this position I have provided in each case upper and lower tongue extensions 26 and 27 which are bentinward so as to bear against the upper and lower edges of the portions 13 and EL-4 0f the tongue illustrated in Fig. 4, and against the upper and lower edges of the portions 47 and 48 in the construction illustrated in Fig. 8. By this means, a head is formed fitting within the channel bar 8, as clearly indicated in Figs. 1 and 6., or in the channel piece 42 indicated in Fig. 7, the locking tongue being then forced rd'ownward so that the body 12 of the tongue, referring to Figs. 4, 5 and 6 adjacent to the portion 12 and 13, and formed by the portions 12* and 12 enters the siotted extension 10 between the head above described and the outwardly flanged portions 16 and 17 or, referring to Figs.
7' and 8, the portions 47 and 48 are forced into the slit opening 44.
From this description-it will be seen that I have devised a very simple form of looking tongue which-may he cheaply made and will at the same time be strong and durable, and an eflicient form of lock.
hat I claim as my invention is The coinhinatio-n with two wall inenihers set at right angles one to the other, of a channel piece secured to one member and having a vertical slit located in the wall forming thebase of the channel, a locking tongue comprising a strip of metal, the body of which is bent i-nterniediately upon itself to form a double thickness adapted to fit into the aforesaid 'slitof the channel ineinher, and having its ends out-turned and the edges of the nutturned portion converging from one end thereof to the other, and a-se curing cap having its sides converging from 'one e nd to the other and intur-nedto conform to the shape of the aforementioned out-turned portions of the body and then inwardly with the inner side of suc houtturned portions and having upwardly and downwardly extending tongue extensions adapted to be 'bent inward to C1engage the out-turned portions of the b0 y onannns "rn'rnin CAMPBELL.
