This invention relates to davenportconstruction.

An object of the invention is the provision of; a hinge construction for davenports which allows a davenport to become a bed-davenportwitha minimum of effort as to actuating the hinge onthepart of the operator.

Another object is the provision of a hingeconstruction for bed-type davenports; which is simple of structure, inexpensive in cost: of manufacture, of few parts, and fool-proofin: its construe tionand operation.

With the above-mentioned and. other objects in view, the invention consists in the novel and useful provision, formation, construction, association, and relative arrangement of parts, members and features, all as shown in certain em,- bodiments in the accompanying drawings, described generally, and more particularly pointed out in the claims.

In the drawings:

Figure 1 is a fragmentary elevation of the ire-- proved hinge for a davenport,

Figure 2 is a fragmentary detail of certain ele-' ments of the invention,

Figure 3 is a fragmentary sectional'viewon the line 3-3 of Figure 1,

Figure 4 is a fragmentary view of'certain' portions of the invention in cooperation withthe back and seat of a davenport, the seat being in a changed position from that shown in Figurel,

Figure 5 is a fragmentary view showing certain elements of the invention in changed rela= tionshipresultant upon a tipping of the seat,

Figure 'Tis a perspective view of one hinge member,

Figure 8 is a perspective view of a second hinge member adapted to cooperate with the hinge member of Figure 7, and

Figure 9 is a perspective view of a bracket which may be used in the practice of the invention.

Referring now to the drawingsl have shown a portion of a davenport, indicated generally as l, which has a back 2, seat 3, and framing 4 adapted tobe supported by the usual legs; The back and seat, by way of example, may both include a rectangular framing carrying the usual coil springs over which is placed padding, followed by upholstering material. Thus, when the back and seat are moved from the position of Figure '1 to that of Figure 6, a bed structure resultsgin which the back and seat are in substantial alignment horizontally. The frame 4 includes what is ordinarily known as a hinge board 5. This hinge board is adapted to carry the elements of the invention, to be described, andsaid board is connected to and becomes a partof the framing 4-. The hinge for the davenportback and seat includes two members 6 and l. A hinge is used at each end of the davenport. Member 6 is best illustrated in Figure 7, and includes a part 8 which is flanged at 9, the part 9' being substantially atright angles to the plane of the part 8, with part 8 formed with an oilset and parallel portion Hi. It will be observed that flange 9 is at an angle other than degrees to the edge portions H and I2 of thepart 8. This construction is adhered to due to the method by which said hinge part is attached t0 the back 2, as shown in Figure 1. In other words, flange 9 is secured to the back, the part 8 extends downwardly and connects with the other hinge part I, thus allowing the, back to have a slight tilt rearwardly relative to the seat. The offset edge l3 mterconnecting parts 8 and it) provides a cam surface at I i,

a notch at l5 at the terminus ofone end of the cam surface, and a cam nose It at the opposite terminus of the cam surface where it joins with the edge 12. The other member I of the hinge is shown in Figure 8 and it, like member '6, provides a body portion H having a flanged end is substantially at right angles to the plane of portion H and at an acute angle to edges wand .26. The opposite end of part I1 is formed to provide a cam edge at 2|, the cam edge being joined with a lip 22 at one terminus thereof, while the opposite end portion merges with a cam recess 23. A nose portion 26 is formed by an extension of edge I9 where it joins with the recessed portion That portion of part I! which includes the cam edge, lip, recess and nose will be designated as an entirety as 25, and the portion 25 is Pro.- vided with a cam slot 26. Cam slot '26 has a curved edge 21 merging with curved ends 28 and -29, the curved ends being joined by a concave edge 30. It is intended that a-bolt or pin should be passed through bore 3! of part II), and through cam slot 26 for holding the parts in assemblage. This same bolt, which is illustrated in Figure 3 at 32, likewise holds certain other elements, to be hereinafter described.

The flanges 9 and 18 are transversely bored at 33 and. 35, respectively, so thatscrews or other means may be passed through said bores for holding the flanges to the back and seat as, for instance, illustrated in Figure 6 at 35- and 36, respectively.

In Figure 9, I have provided a bracket 3- 1. This bracket includes two parts 38 and 39 substantially in right angular relationship. Both parts 38 and 39 are provided with transverse bores, as shown at 4B and 4 I whereby screws may be passed through said bores into the hinge board for securing the bracket in position of service. It is understood during this description that I am describing but a single end of the davenport, and the means used at said end for hinging the back and seat together, and that the opposite end would be identical as to construction and parts. A pair of links 42 and 43 are spacedly secured to the bracket 31 by means of pin connections, as

illustrated in Figure 3 at 44 and 44 The opposite end of link 42 is pinned at 35 to member 6, while the opposite end of link 43 is secured by the pin or bolt 32 which joins members 6 and l together. e V

The link '43 is perforated at 46 and the hinge board carries a small bracket 41, between which :bracket and perforation is a coil spring 48.

The operation, uses and advantages of the in- Vention just described are as follows;

If we assume that two. pairs of hinges, together with the associated links 42 and 43, and brackets 31, have been secured at ends oi the davenport between the back, seat, and hinge board, then the seatv may be moved relative to the back so that the back may assume an angle tov permit access within a compartment located beneath the seat, or topermit the back and seat to assume the horizontal position shown in Figure 6, When the parts are in the position illustrated in Figure 1, the back being at an angle to the seat, link 43 engages a stop. pin 49 carried bybracket 37. This lirnits movement of; the link in one direction and aids in preventing the back from dropping from the position shown in Figure 1. Also, the lip 22 of member I engages the notch l5 of member 6 to prevent movement'between members 6 and I. In other words, members 6 and 1 do not bove on the pin or bolt 32.

When it is desired to lower the back to form a bed, the seat 3 is raised from the position of Figure 1 to that of Figure 2, the bracket! indicating a raised seat position. The pin 32 remains in the end 29 of the cam slot, with the result that the lip 22 engages the notch l5 and holds the seat in its raised position. At the. same timethe back is lowered to a horizontal position, This permits accessby the operator to. any bedding contained in the compartment (not shown), and usually provided beneath the seat. In the raising of the seat from the position oi Figure 1 to. that of Figure 2, the movement is outwardly and upwardly and the load is carried by the links 42 and 43. The link 4:3 is urged forwardly by spring 48, with the result that slight physical effort is exerted to raise the seat to. the position of Figure 2. Having removed bedding from the compartment provided therefor, the seat is tilted further or from the position of, say, Figure 2, to that of Figure 4. This tipping movement brings the breaking cam into action, this breaking cam including the nose l6 and the recess 23. The nose I6 is received within the recess 23 and moves the pin 32 from the position of Figure 2 first into the concave edge 30, as shown in Figure 4, and then into portion 28 of the slotted cam, as shown in Figure 5. The two cam faces 14 and 2| are separated, as shown in this figure. The seat may then be lowered to a horizontal position as shown in Figure 6. When 4 this seat is so lowered, the pin 32 is shifted so that now it engages the portion 30 of the cam slo If it is desired to restore the davenport to theposition of Figure 1, the seat is lifted, which will cause the pin 32 to'be received within the end 28 of the cam slot, whereupon the notch l5 and lip 22 will co-engage, as indicated in Figure 2, andthe lowering of the seat will raise the back to the position shown in Figure 1, During the move-- ments just described, the cam edges l4 and 2| co-engage, to the end that the pin 32 travels to proper position. against the end 29 within the cam slot.

It will be seen that the present invention pro-- vides a shifting pin between the two hinge members, the pin being controlled as to its position by a cam slot and which pin is caused to move within the cam slot by the co-engaging cam edges of the two hinge members, to the end that the twohinge members may assume a locked-againstmovement position, which look may be broken upon moving one of the hinge members, whereupon the cam edges may co-engage so that the hinge members may assume a relative angularity. I have provided, by this invention, a simple means for controlling the position of the back and seat members of a davenport without the necessity of providing spring-pressed pawls, or the like, operating in conjunction with a toothed rack, as is ordinarily employed. The construction shown is positive in its operation, will at all times operate in the same way, with nothing to get out of order other than that caused by wear of the parts.
