Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed November 2, 190 Serial No. 281,087.

1'0 (t/J/ w/ wm/ it miu l concern:

Be it known that 1, CALVIN CONN, a citizen of the United States. and a resident of Brennerton, in the county of Kitsap and State of Washington, have invented anew and Improved Reclining-Chair, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a simple, durable, and economic form of chair which can be used as an ordinary chair or instantly and conveniently converted into a reclining-chair simply by the movement of the body of the occupant.

Another purpose of the invention is to provide such a construction of chair that the occupant may assumea full or a partially reclining position at will and so that the parts will remain in their adjusted position as long as desired and will so remain when the chair is vacated until the adjusted parts are purposely disturbed.

A further purpose of the invention is to so construct the chair that it will be light yet strong and free from all springs and controlling devices adapted to be manipulated by the occupant in assuming different positions in the chair and also to so construct the improved chair that the parts thereof may be quickly, readily, compactly, and flatly folded without disconnecting any of the parts.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the chair,show ing the chair in ordinary position in positive lines and in reclining position in dotted lines. Fig. 2 is a front elevation of the chair as shown by positive lines in Fig. 1. Fig. 3 is a plan view of the chair as shown in Figs. 1 and 2.

spective view of a part of the lower portion of a leg-rest and a portion of the foot-rest,

illustrating the said parts in normal position in positive lines and in reclining position in dotted lines. Fig. 9 is a longitudinal section through an arm of the chair, drawn on an en larged scale, and a side elevation of a combined brace and connecting-link carried by the arm. Fig. 10 is a detail perspective view of one of the couplers employed in connecting sundry of the parts of the chair, and Fig. 11 is a detail perspective View of a part of the upper rear portion of one of the legs and a tip or cap fitted thereto.

The legs of the chair are four in number, being two at each side, and these legs are designated, respectively, as 10 and 11. The legs are crossed at each side of the chair, and each set of legs are pivotally connected by a pivotpin 12. The legs 10 are longer than the legs 11, and the said legs 10 extend from the lower front portion of the chair upward to the back portion at a point above the seat A, to be hereinafter described, while the legs 11 extend from the forward portion of the seat A down ward and rearward to an engagement with the floor or other support.

The back of the chair consists, mainly, of two side bars 13, which extend some distance above and below the seat A, heretofore mentioned, and these side bars 13 of the back are connected at the top by a cross-bar 14:.

A coupling-block B is mounted to slide on each of the side bars 13 of the back, and the said coupling-blocks are preferably constructed as is shown in detail in Fig. 10, wherein a block is provided with a recess in one side, preferably the rear side, and in this recess a spring-tongue 15 is fitted, secured in place by a screw 16 or its equivalent, and at the upper or free end of this tongue 15 a head is formed, and on the inner face of the said head a transverse lip 17 is produced, as is shown by dotted lines in the said Fig. 10, and the recess in which the tongue 15 is placed is so made that a lip 17 will extend into the chamber of the coupling-block and engage with the rear face of the side bar 13 of the back on which the coupling-block is fitted. This coupling-block is adapted to slide on the side bar 13 of the back to which it is applied and is held in adjusted position. by the engagement of the said, lip or rib 17 of the said spring-tongue 15 with the side bar; but when suflicient force is employed the said coupling-blocks may be made to slide on the bars 13, upon which they are mounted, irrespective of the engagement of the lip 17; but as soon as the force has ceased to be exerted the spring-tongues will hold the said coupling-blocks firmly in place.

A trunnion 18 is made integral with the inner face of each coupling-block B, and the ends of the trunnions 18 are adapted to receive machine-screws 19 or their equivalents, and the said screws are adapted to hold washers 20 in place.

A cap or tip C is located at the upper end of each leg 10, and the said cap or tip, as is best shown in Fig. 11, is provided with an aperture 22, extending transversely therethrough. Said aperture 22 of a cap or tip G is adapted to receive a trunnion 18 of a coupling-block B, and after the trunnion of a coupling-block has been passed through the aperture 22 of a tip or cap the washer 20 is applied to the trunnion and is secured in place by the screw 19.

An upwardly and forwardly extending lug or fin 23 is made integral with each cap or tip C, and the-fins or lugs 23 are adapted to enter between the members of the bifurcated rear ends 25 of arm-rests D, one of which armrests is shown in detail in Fig. 9, and each of the lugs or fins 23 is provided with an aperture 24 at its outward or forward end adapted to receive a pivot-pin 26, which pivot-pin is passed likewise through the bifurcated rear end of the arm-rest,being connected as is shown in Figs. 4 and 5.

A longitudinal chamber 27 is produced in the under face of each arm-rest D, and this chamber extends nearly from end to end of the arm-rest, and at the rear portion of the said chamber 27 a plate 28 is secured to the bottom portion of the arm-rest, which plate has a longitudinal slot 29 made therein, extending through the forward end of the plate.

Slightly back of the forward end of the plate 28 a shoulder 30 is produced in the said chamber 27 of an arm-rest D, and the upper wall of the chamber from the shoulder to a point near the forward end of the chamber is upwardly inclined, as is shown at 31 in Fig. 9. Between the terminal of the upper inclined surface 31 and the forward end of chamber 27 a longitudinalprojection 32 is formed, having its ends tapering or inclined, as is also shown in Fig. 9. Thus the chamber 27 of an arm-rest is divided into practically three sections a rear section (Z, an intermediate section (Z, and a forward section (Z A link 33 is pivoted at one end in the forward end portion of the chamber 27 of each arm-rest D, adapted to normally extend downward from the said arm-rest, and a guide-bar 34 is pivoted at its forward end to the said link 33 at the end which is opposite that pivoted to the arm-rest. The guide-bar 34 is provided with a longitudinal slot 35, extending nearly from end to end, and at the rear end of each of the guide-bars 34 an upwardly-extending member 36 is formed, which extends through the slot 29 of the plate 28 of an armrest into the rear section (Z of the chamber 27 of said arm-rest. A pin 38 is passed through this upwardly-extending member 36 at a point above the upper face of the plate 28, as is shown in Fig. 9.

When a link 33 is folded up in an arm-rest D, it fits snugly in the forward section (Z of the chamber of said arm-rest, as is shown by dotted lines in Fig. 9, and at such time the guide-bar 34, connected with the link, will be moved backward at its rear end to the rear portion of the rear section (Z of the said chamber 27 of the arm-rest, as is shown by dotted lines in Fig. 9, and the said guide-bar will at such time substantially rest in the intermedi ate and rear sections of the chamber. The forward and rearward movement of the guidebar 34 is limited by reason of the upwardlyextending member 36 of the bar engaging in its extreme rearward movement with the rear wall of the chamber 27 in the arm-rest and at its extreme forward movement engaging with the shoulder 30. as is likewise clearly shown in Fig. 9.

In connection with the parts just named I employ a leg-rest E, which is at the front portion of the chair. This leg-rest consists of two main side bars 36, which in the normal position of the chair serve as front legs and occupy a vertical position, as is indicated in Fig. l, and between these main side bars 36 the body 6 of the said leg-rest section is located. This body a consists of side members 37 parallel with the main side bars 36, yet spaced therefrom, and a board or a covering 38, which is secured to the said side members 37 in any suitable or approved manner. The said body-board or covering 38 terminates short of the lower ends of the side members 37, as is shown in Fig. 8.

The upper ends of the side members 37 of a leg-rest E are provided with ears 37 and a cross-bar 39, which is in the form of a rod, is passed loosely through the said ears 37 on the side members 37 and through the upper ends of the main side bars 36, the ends of the cross rod or bar 39 being made to loosely pass through the slots 35 in the guide-bars 34, as is best shown in Fig. 6. The seat A consists of a suitable frame 40, usually rectangular in shape, and a covering 41 is secured to this frame. The said frame at its forward end is provided with forwardly-extending lugs 42, preferably integral with its side members, as is shown in Figs. 2 and 6, and the said front transverse rod or bar 39 is passed loosely through suitable apertures in the said forwardly-extending lugs 42 of the seat. The said rod 39 is likewise passed through the upper ends of the legs 11 of the chair or those legs which extend from the lower rear portion of the chair upwardly and forwardly. Thus the rod or bar 39 connects the upper portion of the leg-rest E, the legs 11, and the forward end of the seat A with the guide- 797,841 gay bars 3 1, the connecting medium 39 for said parts having sliding movement in the said guide-bars. The said guide-bars, as has been stated, have sliding movement in the armrests l).

A yoke 43 is secured longitudinally to the upper face of the side portion of the seatframe 40 at its rear, as is shown in Figs. 1 and 5, and these yokes 43 are adapted to receive rings 4: 1, which are secured to the lower end portion of the back 4:5, which back may be of any suitable material, preferably a pliable material. The upper end portion of the back 45 is secured in any suitable or approved manner to the cross-bar 141, connecting the side bars 13 of the back-section of the chair.

Shifting arms 46 have a hinged connection with the lower ends of the side bars 13 of the back-section of the chair, is best shown in Fig. 1. This hinged connection is made usually by securing socket members 47 and 47 to the adjacent ends of the said shifting members 46 and the side members 13 of the back-section, and the said socket members at their outer portions are more or less triangularly shaped, and the hinge connection 18 between the socket members 47 and 17 is substantially that of a rule-joint.

The forward ends of the shifting members 16 are pivotally connected with the main side bars 36 of the leg-rest E of the chair by means of a coupling-block B, and these coupling-blocks have sliding movement on the said main side bars 36, as is shown in Fig. 1. Each of the coupling-blocks B is provided with a trunnion extendingfrom its outer side, the said trunnious 49 being passed through suitable apertures in the forward end portions of the shifting members or arms, as is also shown in Fig. 1.

A foot-rest is employed in connection with the leg-rest. This foot-rest consists of a board 50, which extends in front of the side boards 37 of the body portion of the leg-rest somewhat below the body member 38, as is shown in Fig. 8, and the said board 50, which maybe termed a backboard, is provided with socket members 51, loosely embracing the side members 37, as is also shown in Fig. 8, so that the backboard 50 may be slid up ward or downward on the said members 37.

A footboard 52 has a hinged connection with the forward lower portion of the backboard 50 by means of chains or cables 53, which are secured at one of their ends to the body-section e of the leg-support of the chair and at their other ends are attached to the footboard 52. When this footboard is to be straightened out, as shown in Fig. 8, which may be desirable when the parts of the chair are carried to the inclined position, the backboard 50 must be slid upward on the members 37, as the tie chains or cables 53 are not expansible, nor have theyelastic connection with the parts to which they are applied.

including the legs 10 and 11.

It may here be stated that the couplingblocks B are provided with spring-tongues, preferably at their front portions, corresponding to the spring-tongues 15 described in connection with the coupling-blocks B.

It will be observed that all of the parts of the chair are more or less connected and that it is possible for all of the parts to remain thus connected, no matter whether the chair is folded or whether it is carried from one position to another. Nhen the chair is in its normal position and a person is seated therein, it may be carried to the inclined position by the occupant simply shifting the weight of the body more or less in direction of the back-section of the chair, whcreu pon the backsection will act on the trunnious 18 of the coupling-blocks B, which serve as pivots, and the connected parts of the chair will then assume the position shown in dotted lines in Fig. 1 or a position more or less inclined.

Then the parts of the chair have been ad-- justed by the occupant, the weight of the oecupant will preserve the chair in its adjusted position, and when the occupant leaves the chair the spring tongues on the couplingblocks will serve to retain the parts in adjustment until said parts are purposely read justed.

In folding the chair it is simply necessary to carry upward the rear ends of the armrests D, whereupon the forward ends of the arm-rests D will drop downward and the front lower portion of the chair will be car ried rearward and upward, and the parts of this portion of the chair will be folded one upon the other and against the back-section, Finally the arm-rests are dropped down against the folded parts, bringing, for example, the armrests in a flat position to the front and the side bars of the back to a flat position at the rear, and the other parts will necessarily oc cupy a Hat folded position intermediate of the said arm-rests and the side bars of the back, as is clearly indicated in Figs. 4 and 5.

It has not been previously stated how the lower ends of the side members 37 of the legrest E are connected with the main side bars 36. Such connection is effected through the medium of tie-rods 36, which extend from the members 37 of the said leg-rest to the main side bars 36, as is clearly shown in Fig. 2, the connection between these two parts at the upper portion of the leg-restbeing effected through the medium of the pivot-rod 39.

I desire it to be understood that while the forward and rear legs of the chair are shown of different lengths said legs may be of the same length without departing from the spirit of the invention.
