Specification of Letters Patent.

Patented June 18, 1918.

Application led December 29, 1917. Serial No. 209,486.

To all wtom t may concern.'

Be it known that I, JOHN M. RICHARD- SON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented .certain .new and useful Improvements in Davenports; and I do hereby declare that the following is a full, clear, and exact description thereof.

My .present invention relates to new and useful improvements in foldable couch beds ordavenports, particularly in the mechanism for simultaneously moving the seat and back thereof to expose the bed portion.

Heretofore it has been customary to pro-v vide a rather complicated mechanismv for moving the rback of the davenport out of its normal position upon the raising of the seat to expose the bed portion, said back pivotedto the davenport frame as illustrated in my Patent No.

1,198,480, granted September 19, 1916.

Such construction necessitates a relatively wideor deep article which is most too wide to lbe easily movable through ordinary doorways. One object of the present invention, therefore, is to reduce the front to rear width of the davenport and consequently f decrease the costof manufacture andthe amount of operating mechanism which lhas been heretofore necessary.

An additional object subordinate to the foregoing object is to provide a mechanism whereby the normally vertially 4disposed back may be retained in this position when the davenport is open, yet disposed above the frame and out of the way of the elevated seat.

With the foregoing and other objects in view the invention consists in certain pecularities of construction and combination of parts as set forth hereinafter.

In the accompanying drawing:

Figure 1 represents a vertical sectional View of a davenport or couch bed embodying the features of my invention, the parts of the same arranged in closed or normal position, and

Fig. 2 is a similar view showing the parts arranged as they will appear when the davenport is used as a bed.

In the embodiment illustrated the numeral 1 designates an end piece'of a skeleton davenport or couch bed frame, there being two of the same which are connected by front and rear sills 2 and 3 respectively and a top rail 4:. Between the end piece 1 is disposed a normally horizontal seat A and a substan-` tially vertically positioned back B. When the seat and back are arranged in their normal position as shown in Fig. 1 the folding bed portion C will be hidden from view.

Whenit is necessary to extend the foldable bed portion C the seat and back are raised as shown in Fig. 2, the means for accomplishing such elevation of these parts being the object of the present invention. Said invention consists of a number of suitably arranged links or levers, one complete set of which is preferably used at each end of the couch frame, although only one set is illustrated. Therefore in the following description ofthe details of my invention only one set will be Areferred to.

Specifically the invention comprises an attaching plate or strip 5 of right angular formation, one leg of which is secured to the end piece 1 while the other leg is attached to the top rail 4, an yL-shaped ylink 6. an intermediately pivoted lever 7 and a connecting bar or strip 8. From the drawing it will be noted that the short arm of the L-shaped link 6 is pivoted to the attaching plate 5 adjacent the top rail 4, while the other arm thereof is similarly connected to an attaching plate 9 secured to one end of the back B, said.l point of connection between the link and the back being substantially midway the top and bottom edges of the latter.

A The intermediately pivoted lever is fulcrumed to the attaching plate 9 at a point spaced from the pivotal connection of the link 6 therewith, one end of the lever being pivoted to the attaching plate 9 adjacent the bottom edge of the back B. The other end of the lever is pivoted to one end of the connecting bar 8 which in turn is fulcrumed to a crank plate 10 carried by the seat A. This crank plate also provides the pivotal connection of the seat A with the davenport frame. The pivot of the connecting bar 8 is spaced from the other pivot of the crank plate 10.

In operation the front end of the seat A is raised to rock the same about its pivot, such movement causing the connecting bar to move downwardly and thus rock the lever 7, which lever being pivoted to the back B adjacent its bottom will cause the same to rise upwardly. The L-shaped link 6 retains the back B in substantially vertif cal position throughout its upward movement and holds the same in this position after it has reached its limit. YVhen the seat A has been moved upwardly to a substantially vert-ical position the back B will have reached its limit of movement and will then be positioned vertically substantially directly above the upper or front edge 'of said seat, these parts thereby occupying a very-limited amount'of space and in nowise interfering with the formation or occupancy ofthe bed formed Vby the bed portion C.

An examination of the drawing in this application with that in the patent above re ferred to will. disclose the fact that the frame in thisrinvention may be much narrower than that in said patent. In other words by substitut-ing the vertical arrangementof links andlevers for the geared segments shown-therein the rear wall il of the, davenport is quite close to the back B. In actual practice =the reduction in width is from thirty-two to twenty-nine inches.

l. In afoldablecouch bed7 a frame, a normally substantially horizontally ydisposed seat having its rear' end in pivotal yunion with said frame, a substantially vertical bacK, and means connecting the seat and back whereby' when the seat is raised from a horizontal to a vertical position'thaback will be moved upwardly and disposed vertically above the top or iront edgevot1 said seat.r

In a oldable couch bed, a frame7 a normally substantially horizontal seat having its rear end in pivotal union with the Jframe7 a substantially vertical back, a lever pivotally carried by the Jframe and connected with the back, and a connection between said lever and the seat whereby when the latter is raised from a horizontal to a vertical position the back will be moved upwardly and disposed vertically above the top or front edge of said seat.

3. In a oldable couch bed, a trame, a normally substantially horizontal seat havingits rear end `in pivotal union with the frame, a substantially vertical back, a lever pivotally carried by the'iframe and connected withthe back, alink pivotally connected with thefba'ck and traine, and a connection between said lever and the seat, whereby when the latter is raised from a Vhorizontal to a vertical positionthe back will be moved upwardlyfand disposed vertically abovethe` top or front edge of said seat.

lle. In a oldable couchbed, `a frame, a normally7 substantially horizontal -seat having its rear end in pivotal union with the frame, a substantially vertical back, a'link pivotally connected with the back and frame, a lever fulcrumed intermediate its ends to the frame at a point spaced from the pivot of the link; therewith, one end.

of the lever being piv'oted to the bachata point spaced from the pivot ot the Llink therewith., and a connecting member pivoted tothe other end of the lever the other' end of the member -being pivotedrto` the seat at Y a point spacedirom its fulcrurm whereby when the seat is raised from a horizontalto a vertical position theback will `be moved upwardly and disposed vertically above the top or front edge of said seat.
