Nov. 2& 1939. J. A. scHAUs's RECLINING CHAIR Filed Oct. 5, 1938 Patented Nov. 28, 1939 UNiTED STATES PATENT OFFICE This invention relates to furniture.

This invention has utility when incorporated in a reclining chair.

Referring to the drawing: Fig. 1 is a side view of a chair embodying th invention herein, said chair being in upright position;

Fig. 2 is a view similar to Fig. 1 with the chair` in tilted or reclining position;

1 Fig. 3- is a plan view through the frame of' the chair of Fig. 1, approximately along the line III- HL Fig. 1, looking -in the direction of the arrow, parts being broken away;

1 Fig. 4 is a view on the line IV-IV, Fig; 3, lookbroken away; and

Fig. 5 is a view on the lineV-VQ Fig. 4, look-- ing in the direction vof the arrow.

'Ihe invention herein comprises anarticle of furniture which may bev easily tilted from upright to reclining position by an occupantor the- 30 as by one of greater size and weight. An additional feature is the elimination of tilting about a fixed center, the movement herein being a tilt and rearward glide and in either direction a gradual decreasing speed, a movement free from l jerks and bumps, pleasing to the occupant.

While the disclosure herein is directed primarily to a chair, such invention has utility in day beds, davenports and the like articles of furniture.

The seat portion of the article of furniture herein comprises a front rail I, outer side rails 2, and rear rail 3. Spaced inwardly from each outer side rail 2 is an inner side rail 4 also eX- tending from the front rail I to the rear rail 3.

Upwardly extending from the forward portion of the side rails are members 5 and upwardly extending from the rear portion of the rails 2 are members 6. These members together with arm rest members 'I completes a frame to receive cover upholstery 8.

Mounted by pins 9 between each pair of side rails is a block I0 whose upper face is iiush with the upper edges of the side rails. Such upper faces furnish an ample platform to which the webbing of the seat structure may be attached.

ing in the direction of the arrow, parts being The lower faceof each blockv I 0 is contoured to providea major or greater general radii concave. bearing or slide surfaceV I2 and a minor or less general radii' convex bearing or slide surface I 3.. These surfaces may be on individual blocks 5" or even onk the side: rails but for the additional strength Vin commercial production such are shown" here as on singleor integral blocks I0.

The base portion of this article of furniture y comprises a` pair of blocksv I4 extending upwardly 10` from the'iioor between the

side rails

2, 4, such -

side rails

2, 4, having depending skirts I5, I6, ynot only' providingl steadying means for the blocks I4, but nearly housing such blocks for a y more sightly appearance. The' outer skirts I5 15` are of greater extentforshielding theV blocks I4 but kthey alsol provide mountsfor pins IT which extend into cut-out regions I4 of the blocks I4. When the chair is shifted or lifted, the pins I1 engage-the blocks I'4- and thereby retain proper 20Fy assembly ofthe base members with thel seat portion. .Y l

'I'he upper faces of the blocks I4 are contoured to provide minor convex bearing or slide surfaces I 8 having a lesser general radii and 25 major concave bearing or slide surfaces I9 having greater general radii. The concave seat bearing surface I 2 contacts and' rests on the convex base bearing surface` I8 but in that the general' radii of the face I2 are greater than the face I8 there 30 is but tangential contact. The-convex seat bearing surface I3 contacts and rests on the concave base provided bearing surface I9 and in that the general radii of thesurface I9 is greater than the surface I3, here also there is but tangential 35 contact.

The faces of one of each pair of contacting bearing surfaces may be provided with a metal facing 20 of bronze` or other suitable metal for a smoother glide. The opposing faces may be 40 lubricated to also add to the ease of operation. The design of the lbearing surfaces is such, however, that an extreme minimum of lubricant is necessary.

lWhen the chair is in upright position, the dis- 45 tance 2| between the bearing face contact points is considerably less than the distance 22 when the seat is in inclined position. 'Ihis is due to the particular contour of the bearing faces which may be true arcs of circles in certain sizes of 50 units or vary therefrom in arcuate curves of more or less general radii designed to provide the maximum ease of movement in the particular size or pattern of chair or other article of furniture. 55

as the front legs 24 come into oor contact as forward limit stops.

There is thus provided a `chair having` an easily controlled and pleasant movement free` from limit bumps and jars, Whichchair' c0117;l

structed with a minimum 'of partsc'f What is claimed and it is desired by United States Letters Patent is:

11. In an article of furniture, a base providing -a pair of arcuate slide bearing surfaces, one

convex andthe other concave, and a seat providing a pair of friction-slip coacting arcuate slide bearing surfaces, one convex and the other concave, the arcuate extent of the base and seat surfaces differing to provide a shiftable and differential intermediate length tangential Contact in relative movement therebetween.

2. In an article of furniture, a base providing a pair of arcuate slide bearing surfaces, one convex and the other concave, and a seat providing a pairof friction-slip coacting arcuate slide bearing surfaces, one convex and the other concave. 3.
