9 Claims.

It is one of. the-more important objects of the present invention to combine these separate parts to function as a single unit, either as a leg or asa catch. In this respect it is a further object to simplify and reduce the number of parts and cost of manufacture by utilizing a single piece" of mechanismwhere formerly it required the use of two.

A furtherobject is to provide more positive means both for maintaining theleg in its adjusted-position-while supporting the backof-the davenport in anextended position and for maintaining the'back upright when the davenportis utilized asa seat. The latter means issupplie'd by the use-of a prong forming a part of the leg which prong engagesan eye-bolt secured in the arm rest of the davenport.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawing'which illustrates what is at present deemed to' be a preferred embodiment of the invention,

Fig. 1 is'a fragmentary'perspective' view-of a corner portion of a davenport showing the invention applied thereto, a portionof the upholstery being removed adjacent the applied device. Fig. '2 is" an enlarged fragmentary horizontal sectional view-taken on-line 2-2- of Fig; 1, some portions of the structure being shown in lan. Fig. 3 is'a fragmentary elevational view looking in the direction of the pointing arrow 3 found in the lower left hand part of-Fig. 2.

Fig; 4 is a fragmentary elevational view showing the catch functioning as a leg: when supporting the back inan extended position.

Fig.v 5 is a detail perspective view of the pivot means .for adjustably supporting the combined leg and catch.

Fig. '6 is a perspective view 'ofithe complete davenport'showing-the' improved leg and catch functioning in full and dotted line positions;

13 adjacent the opening [2;

swung position as shown in Fig 1.

Fig. 7 is an end elevation of the davenport func= tioning; as. a bed.

Referring in detail: to the drawing, 6 indicates the back of the davenport and l thearm rest thereof. Into-each end portion of'saidarm rest is screwedan eye-bolt 8 provided with the eyeopening 8a and horizontally spaced from said eye-bolt into the up-swung davenport back is secured a circular brackets for adjustably supporting the combined leg and catch Id, said bracket being provided'with-acentral annular recess l l' in one face thereof and'an axial opening 12 of lesser sizethan said recess and communicating "there?- with inthe face: of said bracket which is opposite said recess thereby providing'an annular shoulder cooperatively joined to the bracket 9 by'means of screws screwed into theback of the davenport is a circular plate l5 provided with a central recess or depression IS.

A circular bearing I! has a circumferential flange I 8: rotativelyimounted with a'working fit in the'recess H between the inner face of the plate l5 and the shoulder it, there being an axial bore l9-through the flanged end of said bearingwhich axially alines with the recesslfi andforms'a continuation thereof. Said bore 19 ispreferably of a length equal. tothe combined lengths of the recess H and opening l2.

The circular body portion of the bearing H extends loosely through and projects beyond the outer face of the bracket 9, there being a deep transverse slotZD extending all the way diametrically across'the projecting portion of. the bearing I] as fully shown inFigl 5 dividing itiinto an upipersegrnent 2 I and a lower segment 2-2.

Diametricallyopposite holes 23- and 24 provide for the mounting of a pin 25 between the arms formed by said upper. and lower segments, said pinbisecting.thezproducedaxis of the bracket I1 atla right angle to said segmentsat a-poin-t-midway of. theinlength.

about the pin 25 through the desired angle in the slot 2! whereby its catchprong 28 may be fed into the opening 8a and when so engaged maintainv the davenport back 5 in the upright or up- V In o-rder to provide for the latter operation the combinedleg and catch together 'withthe bearing 11 arelro- =tated in-an anti-clockwise fashion in a plane parallel tothe back of. the davenport sufficiently far to permit the point of the prong to enter the eye 8a and then the parts are given a clockwise turn until the operation of seating the prong securely in the eye is completed.

When it is desired to use the combined leg and catch as a leg the prong 28 is detached from the eye 8a by an anti-clockwise movement and the back 6 is permitted to lower to a point adjacent the floor 29 as shown in Fig. 4, during which movement the leg 30 is manually swung to a perpendicular position with the back and the end of the leg adjacent the slot 26 is projected into the bore l9 until the inner end of the leg seats in the depression [6, the elongated slot 26 providing for this telescopic seating of the pivoted end of the leg, the frictional contact of the leg in the bore suflicing to maintain the leg thus positioned without endangering it dropping by gravity while the back is further lowered to the point wherein the foot 3| of the leg rests upon the floor 29 in a temporary locked condition.

When it is desired to adjust the back to its upright position and lock it so, the back is elevated sufficiently far to withdraw the leg from its tele- 'scopic relation with the bore I9 and recess I6 and at the completion of the up-swung movement the leg is rotated in a clockwise direction during which movement the prong is simultaneously fed into the eye opening 8a.

It will be seen that the eye-bo1t 8, functions as a latch element, with which the legs laterally extending catch arm or prong 28 co-operates. swingable leg consists of a single straight run and said prong is spaced a considerable distance from the attached end of the leg, being located between the free end of the leg and the axis about which it swings. These co-operating catch and latch elements may be varied as to their details, without departing from the scope of the claimed invention, provided they are related to the leg and back of the davenport in the manner which has been described.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the subject matter claimed.

" What I claim is:

1. In a davenport having a swingable back and an upstanding arm rest at each end of said back,
