3 claires.V v(o1. sii-99) This invention ,appertains to extension tables, and more particularly to folding or collapsible legs for firmly supporting the central part of a table vwhen the table isin its extended position. One of the primary objects of my invention is to provide a table 'leg iixture'which willbe easily and simply operated, and which will effectively hold and lock the leg either in its folded position under the table top, or in its operative, lowered floor-engaging position against laccidental dis' placement or movement.
A still further object of my invention is to provide a table leg iixture embodying a table bracket having parallel side walls vbetween which the leg and its bracket swing, the side walls having keeper notches therein adjacent its opposite ends, and an arcuate guidesurface between the keeper notches, with atransverse latch slide'bolt carried by the leg bracket movable over the arf rangement, and formation of parts, as will -bev hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:
Figure 1 is a fragmentary, perspective View of an extension table provided with the hinged supporting legs.

Figure 5 is a detail, sectional viewtaken at right angles to Figure 4 and on the line 5-,5 of Figure 4.
Figure 6 is a view similar to Figure 3 and showing the leg being swung to its collapsed poy sition, the latch bolt being shown in section.
`Figure 7 is a fragmentary,side, elevational Y y' Figurek 8 is a view similar to Figure 7, but looking from thev opposite sidev thereof.
Figure 9 isa sectional view taken on the line 9-9 of Figure l, looking in the direction of the arrows.
Figure 10 is a horizontal, sectional view taken on the line Ill-I0 of Figure 7, looking in the direction of the arrows.
Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter T generally indicates an extension table, which can be of any desired size, style, or character.v The table can include end" sections I5 connected together by extension vtable-slides I6 for supporting removable table leaves Il.
My invention relates to a'xture I8`for hingedly connecting legs I9 to the table for supporting an intermediate part of the table when the table is in its extended position. A bridge lboard or bar 20 can beremployed for carrying the fixtures v I8 and the legs I9, and this bridge board can be rigidly secured to certain sections 2| of the extension table-slides, and, hence, the bridge board extends transversely of the table and under the Y top thereof.
In one preferred form, my fixture I8 includes l y a table bracket 22, and this bracket can be of a substantially U-shape in cross section, and conssts of spaced, parallel, side walls 23 and a connecting top Wall24. `The top wally 24 is rigidly' secured `to the bridge board 20 on the lower face thereof by suitablek fastening elements, such as screws 25. edges provided with varcuate guide surfaces 26, which lead to keeper notches 2l and 28 arranged adjacent the ,opposite ends of the side walls. These keepernotches are disposedat substantially right angles to one another.' I
Arranged betweenthe side walls 23,V of the leg bracket la is a table 1eg bracket -2a. This table legbracket 29 is also of a U-shape incross section, and, hence, includes spaced, parallel, side walls 30 and a connecting back wall 3l. This back wall 3| is rmly secured to'the leg I9 by means of screws 32 or other suitablefaste'ning elerrients. The upper end of the leg bracket 29 1s pivotally connected to kthe table bracket I ilI bymjeans of at transversely extending pivot' pin The sidewalls 23 khave their outer y 33. This pivot pin extends through the side walls 23 of the table bracket and the side walls 30 of the leg bracket, and the pivot pin is positioned adjacent the inner corner of the table bracket between the keeper notches 21 and 28.
By this arrangement, the leg and its bracket swing between the side walls 23 of the table bracket, and when the leg is in its extreme lowered, operative position, the upper end thereof iirmly abuts the lower surface of the bridge board 20, as can be clearly seen in Figures 3 and 4.
One of the primary objects of the invention is the provision of a simple and durable means for firmly holding the leg either in its lowered, operative position, or in its raised, inoperative position against accidental movement, and the holding means is so formed that the same can be conveniently and expeditiously operated by the user of the table without undue efort.
This means includes a slide latch bolt 34, which extends transversely across the leg bracket. The side walls of the leg bracket are provided with suitable openings for receiving the latch bolt 34, and the walls of the openings are extended inwardly to provide guide sleeves for the bolt. The bolt is so disposed on the leg bracket that the same will ride on the arcuate guide surfaces 26 of the table bracket from the keeper notches 21 to the keeper notches 28 and vice versa.
Adjacent the opposite ends of the slide bolt 34 are annular grooves 36, and vone end of the bolt can be provided with a manipulating thumb piece, if so desired. The grooves 3B are normally held out of engagement with the keeper notches 21 and 28 by an expansion spring 31, which is coiled about the bolt. One end of the spring bears against one side wall of the leg bracket,
and the other end of the spring bears vagainst a suitable abutment, such as a cross pin 38 carried by the bolt.
In use of my xture, the bolt normally occupies the position shown in Figures 1 to 5, in-
clusive, and if the leg is either in its raised, in-
operative position or in its lowered, operative position, the bolt will engage the walls of the keeper notches or recesses, and inadvertent movement of the leg will be prevented.
When it is desired to release the latch bolt so as to swing the leg to one of its two positions, the latch bolt is pressed inwardly to the right (see Figure 5) against the tension of the spring 31, which will aline the annular grooves 36 with the walls of the notches, which will permit the bolt to ride out of the keeper notches, and the walls of the groove will ride on the arcuate faces 26 of the leg bracket, and the engagement of the walls of the grooves will prevent sliding movement of the latch bolt.
When the leg reaches the extreme end of its movement, the latchbolt will then ride into the adjacent keeper notches, and the bolt will then be automatically sprung with a clicking noise into its locking position, with the grooves out of alinement with the notches. Hence, it can be seen that the bolt engages the table bracket at all times, and the table bracket itself holds the latch bolt in its released position during the swinging of the leg from its raised position to its lowered position, or from its lowered position to its raised position.
In Figures 1 to 10, inclusive, I have illustrated a slightly modified Aform of my fixture, and in these figures the modified xture is generally indicated by the reference character M, and the bridge board is indicated by the reference character 40, and one swinging leg bythe reference character 4|. y
The iixture M includes a table bracket 42, which is of a channel shape in cross section and includes top and bottom parallel iianges 43 and a connecting side wall 44. The top flange 43 is firmly secured to the bridge board 40 by means of fastening elements, such as screws 45. The side wall 44 of the bracket 42 is provided with an arcuate guide slot 46 terminating in circular keeper openings 41. The arcuate guide slot 4l) and the keeper openings 41 form in substance a keyhole arrangement.
Arranged in spaced parallel relation to the table bracket 42 is an angle bracket 48, and this angle bracket is rmly secured to the bridge board 40 by means of screws or other fastening elements 49. One part of the angle bracket is arranged in parallel relation to the wall 44 of the bracket 42.
The inner face of the leg 4| has rigidly secured thereto by means of screws 5D a leg bracket 5I. This bracket is arranged at the upper end of the leg and is received between the bracket 42 and the angle bracket 48. 'Ihe leg bracket 5l is of a U-shape in cross section and includes parallel side walls 52 and a back wall 53. A pivot pin 54 connects the upper end of the leg bracket to the table brackets 42 and 48, so that free swinging movement of the leg 4I is permitted.
Slidably carried by the table bracket is a transversely extending latch bolt 55, and the side walls 52 of the leg bracket are provided with openings for receiving the bolt, and the walls of one of the openings can be pressed inwardly to denne a guide sleeve 56 for the bolt. The inner end of the bolt is slidably mounted within the guide slot 45. This end of the bolt is provided with an annular groove 51. The groove 51 is normally held out of the slot by means of an expansion spring 58, which is coiled about the bolt, and one end of the spring bears against one side wall 52 of the table bracket 5l, and the oth'er end against a cross pin 59 fastened to the bolt. The end of the latch bolt remote from the groove 51 is provided with a manipulating thumb piece 55, and this thumb piece also limits the inward sliding movement of the bolt against the tension of the spring 58.
In use of this form of my fixture, the inner end of the bolt normally rides on the walls of the arcuate slot 4E from one keeper opening 41 to the other, and when the leg reaches one of its two positions, the bolt rides into the adjacent keeper opening and prevents movement of the leg.
When it is desired to release the leg, the bolt is slid inward by pressure thereon until the annular groove alines with the walls of the keeper opening and the arcuate guide slot 46, at which time the bolt can be slid out of the keeper opening by swinging the leg.
From the foregoing description, it can be seen that I have provided an exceptionally simple and durable form oi leg xture, which will be easy and simple to operate.
Changes in details may be made provided they do not 4depart from the scope of the claims, but what I claim as new is: v
