cor 0R COUCH.

To all ac/2 0m. it may co/tceivg;

Be it known that I, Joi-i'iv L. TANDY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Cots or Couches, of which the following is a speci fication.

This invent-ion relates to cots or couches of that type having hinged wings and head and foot frames, and my object is to produce a cot or couch of this character in which the end frames at the head and foot shall extend beyond the sides of the cot or couch body when the wings are horizontal.

A further object is to provide means through which the head and foot frames are utilized as anchors for the support of the wings when horizontal.

\Vith these and other objects in view as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1, is an end view of a cot or couch embodying my invention. Fig. 2, is a top plan view of the construction shown by Fig. 1. Fig. 3, is a fragmentary end view showing the structure when folded to form a crib. Fig. 1, is an enlarged view of a catch forming a part of the structure. Fig. is a detail perspective view showing the construction of one of the end rails of the body of the cotor couch and one of the end rails of a wing of the cot or couch. Fig. 6, is a fragmentary end view of a cot or couch of modified construction. Fig. 7, is a plan view of the same. Fig. 8, is a fragmentary end "iew of a cot or couch in which the end frames are rigid. Fig. 9, is a section on the line IXIX of Fig. 8. Fig. 10, is a perspective view of a part of one of the end frames of the construction shown by Fig. 8.

In the said drawings, 1 indicates the frame or body of a cot or couch provided with hinged wings 2 of the same general type as shown in Patent #1,0O6,1 17, issued to me October 17, 1911.

In Figs. 1 to 5 inclusive, the head or foot frame shown. consists of a'- pair of slightly bowed bars 3, and a pair .of catch bars 4, one end of each bar 3, being pivoted to the adjacent end of said body, and the catch Specification of Letters Patent.

bars 4 extending downward through slots 5, in the adjacent extremities of the body. In the vertical plane of said slots the juxtaposed wings 2 are provided with slots (3, which when said wings are horizontal, form in effect parts of the openings produced by slots 5, and for convenience the wings are provided with upturned teeth 7 at the closed ends of said slots 6. Each catch 1 is provided in its outer edge with a notch 8, and in its inner edge with anotch 9, the former being adapted for engagement with a tooth 7 of the adjacent wing when the same is horizontal, as shown at the right hand side of Fig. 1. Vhen said wing is raised to its highestposition, as shown in Fig. 3, where it forms the side of a crib, the notch 9, is in engagement with the body at the inner end of slot The head or foot frame is provided at its ends with extensions, consisting in Sheet 1, of a pair of links 10 and 11, pivotally connected together and pivotally connecting the head or foot frame and the wings together. Below the pivotal points of connection of the extensions with the head or foot frame, the catches are provided with slots 12, which are widened at one side of their lower ends to form substantially semi-circular notches or sockets 13, and pivotally engaging these slots are projections or pins 14 at the upper ends of bars 15, pivoted at their lower ends to the hinged wings 2, and constituting wing supports.

To raise a wing, from a pendant position as shown at the left hand of Fig. 1, to a horizontal position, as shown at the right hand side of Fig. 1,it is grasped and swung upward. In this movementthe extension contracts slightly and the catch slides upward through slot 5, under the push of bar 15, through the engagement of its projection or pin 14, with the upper extremity of the slot 12, and this push and the added push of links 10 and 11, applied above the pivotal point of the catch with bar 3,swing the former outward, so that, as the wing passes above a horizontal position, the notch of the catch shall engage the tooth 7. As this is accomplished the movement of the wing is reversed, that is, it is lowered and in such movement the projection or pin 14 drops to the bottom of slot 12 at a point below the pivotal point of connection of the catch with bar 3, and exerts an outward pull on the lower part of catch 4:, so as to maintain the notch 8 thereof in engagement with the tooth and thus locks the wing in rigid relation to the body and head or foot frames and incidentally also locks the eX tension in position, it being noted that the use of the tooth T, guards against: accidental unlocking moven'ient, as it necessitates an upward movement of the wing preliminary to lowering the same to pendant position.

To lower the wing it is tirst lifted to cause the projection or pin it to engage the notch or socket l and thereby exert pressure on the 'atch whereby the same will be disengaged from the tooth T. As this result occurs, the movement of the wing is reversed to cause the 'at'ch to slide downward through the slots 5 and t3 and to withdraw the j'n'ojection or pin it from the notch or socket 13 to permit the former to slide upward in slot Should it be desired to convert the structure into a crib when the wings are horizontal, each wing is grasped and 'aised. In these actions, the projections or pins Ll enter notches 123 and exert inward pressure on the catches. at. points below the pivotal points of connection of the latter with bars 3, which pivotal points act as fulcrums so that the -atches are swung out of engagement with teeth 7. In such upward movement the projections or pins it slide upward in slots 12 and the links 11 swing around until arrested by contact with pins 16, projectiing from the wings, the direction in which each link 11 swings with respect to the adjaeentwing being indicated by the arrow, Fig. l. -"is this occurs the parts occupy the position shown in Fig. and the notches 9 of the catches engage the end bar of the bod at the inner ends of slots and guard against; reverse or downward movement of the sides or wings. Such downward movementis also guarded against by the links 10 and 11 as folded, and it will be noted by reference to Fig. I, that when the wings are pendant, the pins 16 prevent links 10 and ill from swinging into such near alinement as to have a tendency to lock and interfere with the free upward movement of the wings.

To relower the wings from the position shown in Fig. 3, the operator manually moves the lower ends of the catches outward to free such ends from engagement with the end bar of the body, and swing links 10 and ll upward and oiiitward to approximately a horizontal position. The wings are then swung outward, the lowering movement being continued if desired, until the wings have attained their original or pei'idantpositions.

In Figs. (3 and T, 17 indicate upwardly bowed bars coi'responding to bars 3 in lOCL- tion and arrangement provided with longitudinal slots 18, formed at their inner extremities with offset notches 19, and near their outer extremities with notches 2t), and pivotally connecting the outer ends of said :-lotted bars with the wings are bars .21, corresponding to bars 15 of Sheet 1, the bars 17 and 21 together constituting a head or footframe of greater length than the width of the body. are bars pivoted at their outer ends to the wings and provided at their inner ends with projections or pins 22 for .-lidable engagement with slots l8, these bars corresponding in function to bars 15. tl'hen the wings are pendant, the projections cr pins 13 engage the slots 18 at their outer cxtremities. When the wings are horizontal the projections or pins 2;) engage the notches 1ft! of bars l7. and lock the parts rigidly in position. When the. structure is converted into a crib, that is when the wings extend upwardly as shown in dotted lines Fig. (5, the pins or projections 23 engage the notches li at the inner ends of slots 18, and lock the parts rigidly in position. hen the structure is converted into a crib, that when the wings extend upwardly as shown in dotted lines Fig. b, the pins or projections 23 en gage the notches 15) at the inner ends of slots 18, and lock the parts rigidly together.

ln Fig. 8, the body of the cot or couch is shown as equipped with a rigid end frame consisting of vertical bars 2% and a. horizontal bar connecting the vertical bars, and said bar :55 is provided with slots 26 having notches 27 and 28 corresponding to notches 1S) and 20, of l igs. t and T. In .lieu of bars 21, toggles consisting of links 29 and 30 connect wings 2 with the adjacent ends of the end frame and constitute extensions tbereo'l. and the parts 31 corresponding to parts of Figs. (5 and Y, are provided with projections or pins 32 for movement in slots 26, and for engagement with the notches or and Q8 accordingly as the wings scckets .11: project vet-tic: lly upward from the plane of the bo y occupy the same plane as the body. When the wings 2 occupy pendant positions, the upper ends of links 31 are disposed at the outer ends of slots 26.

From the above description it will be apparent that I have produced a cot or couch embodying the features of advantage enumerated as desirable and while I have illus trated and described the preferred embodiment of the invention, 1 wish it to be understood that i do not desire to be restricted to the exact details of coi'istruction shown and described as obvious modifications will sugg s" themselves to one skilled in the art.

I claim 1.. it cot or couch, coinrn'ising a body, wings hinged to opposite sides thereof, a head frame and a foot f nine, wing supports pivotally connected at. their outer ends to the wings and slidably connected at their other ends to the head and footframes, extensions for and connecting the head and foot frames with the wings, and means for securing the wing supports to the head and foot frames at different points of the latter.

2. A cot or couch, comprising a body, wings hinged to opposite sides thereof, a head frame and a foot frame provided with slots, extensions for and connecting the head and foot frames with the wings, and wing supports pivotally connected at their outer ends to the wings and provided at their other ends with projections or pins engaging said slots.

3. A cot or couch, comprising a body having upwardly projecting frames at its head and foot ends, wings hinged to opposite sides of the body, extensions for and pivotally connecting said frames at points above the plane of the body, with said Wings, and means to secure the wings in horizontal or upwardly projecting positions.

In testimony whereof I affix my signature, in the presence of two witnesses.
