Wylie-ation filed August 56, E916.

To all whom 2?? may conocen.'

de it known lhat l, lil-Lener (inserieren, a' subject. of the King of England, residing at. `High Wycombe7 in the county of Buckingham, -i'llngland, have invented certain nee.T and useful .improvements in Chairs, Couches, or the like, oi' which the ollowinv' is a speciheat-ion.

rl`l1is invention relates to chairs., couches or the like and more particularly to those which are provided with an angularly adjust-able back-member `which is subjected'to the action of a spring tending to return same bo raised or normal position and wherein also the seat-member is pivoted and the rear end thereo'i1 has imparted to itrising and falling movements in accordance with the angular adjustments of the back-member.

The invenion consists in certain novel Eeatures of construction hereinafter fulli described and claimed, these features being brieliy as followsz- The back-member is connected to the rear o the pivoted seat-member by means of detachable eye bolts, and these latter may extend at one end through plates secured to the underside ofthe seatanember, and at the other end through a rail or cross member forming part of the back-member and are secured at both ends by nuts.

The seat-member has a iiXed pivot at its extreme forward end and is suspended from the back-member by detachable bolt connections.

A locking device for the back-member is provided of the type which includes a notched plate engageable by a bolt under cont-rol of the occupant, the improved con struction comprising a lever pivotally mounted outside a frame member in a vertical direction with a spring bolt connected to said lever, and the notched plate being secured to the side of the baclemember between the latter and the frame and adapted to be engaged by the spring bolt.

A latch is provided adapted to engage the lever for rendering the spring bolt inoperative 2xt-Will.

The back member is pivoted in the frame by means of across-rod, which is located at the base of the back-member and inclosed by said member for substantially its entire necicaion o i Letters Patent.

length, the protruding ends oi said rod being plvoed in fixed relationship to the rame in bearing plates detachably connected to the inside of said frame, and held in said bearing plates by Cotter pins.

:in improved form of leg rest is also provided, comprising a frame slidable under the Vplied thereto:

3 is a detail side elevation on an enlarged scale showing part of the back-inembera'nd means for holding0 same in adjusted posit-ion. 4 nig. i is a section of Fig. 3 on he line lit- B thereof.

Fig. 5 is a side elevation showing the parts ofthe leg-rest in collapsed condition and Fig. 6 is a detail view showing guiding means for said leg-rest.

ln said drawings the main -frame of the chair is shown as comprising front and rear legs or uprights {l} and (L2 respectively,n a 'ms (1,3, and general chair structure parts. 7) des ignates the baek-men'iber which is shown as suitably upholstered and which may be formed in 'any appropriate manner` this member beingr pivoted in the rear uyirights (L2 by means of a rod b1 extending through the back-member so as to be hidden from view, the protruding ends of said rod each resting in a slot in the upper end of a. bear ing-plate ZF secured to the inside fac-e of each of the uprights a? as by screws Z13 and the rod being secured against accidental removal from said slots by means oi' Cotter pins b". rlhe said protruding ends of the rod between the back-member and the bearing-plates are encircled by thick Washers b5 secured to che back-member as by screws 5G and which serve to prevent thel rod from working loose Sil Oli

on the haelt-member and maintain it in position between the hearing-plates.

The upholstered seat-member c is pivotally attached to the front rail r1 or' the chair structure positioned between the front uprights a1 as by a pair of hinges c3 and the rear end of this seat-member is suspended from the rail or cross frame 67 of the backmemher Z by means of a pair of eye-bolts cAL fivhioh are each passed at one end through ya met-al plate c secured to the under side of the seat-member and at the other end through said rail or cross frame L7 being; ser cured at both ends by nuts o. lily reason oi this construction, it follows that. when the occupant oi: the chair hy movement of his body forces the haelt-member into a reclining, position, the rear end oi the seat-member is automatically raised at the same time, a feature which adds materially to the comfort and rest al'orded by the use oi' the chair.

d. helical spring c? at the hac-lr or the chair is secured to the back-rail of the seatniemloer c by a. hook or the like es and at the opposite end in the same Way to thehackrail a5 of the chair frame, or the first mentioned end may he secured to the rail Y of the haclememher, so that said spring has the eiiect of restoring the back-member and consequently the seat-member to normal position when the locking device hereinafter referred to iS released. l

l? or packing, transport or other purposes, the hack-member may he readily released from the chair structure by unsereiving the nuts c belowY the seat-member, withdrawing the Cotter-pins lf and unhooking; one end or' the springr c" whereupon said back-member may he placed upon the seat-member hetween the arms of the chair and thus occupy a minimum of space.

The locking-device for securing,f the haekrneinber in desired position comprises a plate al secured outside one of the rear uprights a2 and a second plate Z1 secured to the inside thereof each as by screws d3. These plates form bearings and guides for a spindle Z5 having at its end a catch all under the action of a spring; el and pivoted outside the chair to one end oit' a lever CF fulcrumed at d5 in lugs d formed on the plate (Z, the opposite end of said lever being enlarged as at al for ready manipulation by the hand of the occupant. rl'he spring l tends to force the catch d4 into engagement with one of a number o notches e1 formed in a curved plate e secured to the side of the back-memher, so that said back-member may be. held in any position of adj ustment corresponding` to said notches and may be released by the occupant of the chair 'by pressing inwardly against the end 11 of the lever 7; but for the purpose of allowing the back-member to have freedom of movement l prov-ide a latch j pivoted to the plate d and adapted to engage and retain the lever in the depressed position mentioned whereby the cat-eh d* cannot engage the notches in the curved plate e, rllhe leg-rest above referred to consist-s eti a iframe g which is tong-ned at the sides .as at g1 to run in two grooved rails a coinprised in the chair frame and secured io he front and rear uprights al ando?. Pivoted at g2 near the. outer end or' said iframeg are elevating arms or a frame g3, to the outer ends of which hinged at y"i the upholstered lop; rest g which as shown in Fig. l maj,7 he raised into position for use as a continuationoi the seat-member c, or may be collapsed as shown in Fig'. 5, whereupon the whole may be slid on the rails e. below said seat-member. The leg-rest may he secured against movement in relation to the arms or frame g3 as by means of a hutten hinge o catch g6 or other suitable device or magr he left free relatively thereto so that the leg); rest may accommodate itself to movements of the oceupants legs as desired.

l do not limit myseltu to the exact arrangement. or construction olf parts hereinbefore described and illustrated in the aecompanying drawings since 'the same may he varied `within limits prescribed by the followingclaims without departing Jfrom the l spirit of ltheA invention.

lVhat l claim and desire to secure by Letters Patent of the United States is l. i chair or conch, comprising, in con"- binaton, a frame embodying pairs of front and rear uprights, and erossrails connecting' the same; a baci; member pivotaliy mounted between J[he rear upright-s and provided with a substantially-horizontal eI'oSsn plate which is located below its pivotal axis; a seat pivotally mounted at its yfront end upon the front cross-rail; a plate secured to the under face of said seat at the rear end thereof and projecting rearnnrdlj,7 beyond said end and beneath said cross-plate; and depending' eye-bolts pivoted at their upper ends to said cross-plate and at their loiver ends to said projecting plate, so as 'to lift the rear end of said seat when said baci; member is swung' rearwardly into inclined position.
