FOLDING CHAIR Filed July 1'7, 1930 2 Sheets-Sheet 2 Patented Feb. 23, 1932 PATENT OFFICE GEORGE W. HAMBROOK, OF CHICAGO, ILLINOIS, ASSIGNOR TO CLARIN MFG. C0., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS FOLDING CHAIR Application filed July 17, 1930. Serial No. 468,494.

'lhis invention relates to the art of folding chairs, and has reference more particularly to a folding chair designed and adapted for use in churches, mortuary chapels, etc., and commonly known as a cathedral chair.

In association with such chairs, it is quite common to provide what is known as a kneeler; that is, a low stool placed directly behind each chair 'to accommodate a kneeling posture. sociation with the kneeler as a separate article, considerable extra time is involved in equipping the audience room and subsequently clearing it over the time involved in merely placing and removing the chairs alone.

It has also heretofore been known to pivotally connect a hneeler attachment to a rear rung of a folding chair so that the attachment might be swung up to a position beneath the seat when not required for use.

rlhe device of the present invention is of the latter type, and one object of the inven* tion has been to provide a construction wherein, as the chair is folded, the kneeling pad or stool will be automatically folded along with the other foldable parts of the chair; and a further oby'ect of the invention has been to provide a construction of this type wherein the kneeling pad or stool will be automaticah ly folded to a position between the opposed inner side legs of the chair so as to lie in the same plane with the folded seat and back frame when the chair is fully collapsed. An-

other object is to provide a constructionl 'whereby the kneeler will not only be automatically folded as the chair is folded, but will remain in folded position when the chair is unfolded; and a still furtherobject is to provide a construction wherein, as the chair and hneeler are folded, the latter will be automatically yieldably locked in folded position.

In the accompanying drawings I havevillustrated my present improvement as applied to a folding chair substantially identical with that disclosed in Letters Patent to Rosenthal and Clarin, No. 1,600,248, September 21, 1926; but it will be understood that the improvement is equally applicable to many other types of folding chairs and is not lim- `Where such chairs are used in as ited to the specific structure of the chair herein disclosed.

Referring to the drawings- Fig. 1 is a side elevation of the chair in unfolded position, also showing the kneeler in unfolded or service position.

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Fig. 3 is a vertical front and rear section showing the kneeler folded in full lines, and unfolded in dotted lines.

Fig. i is a rear elevation of the chair in fully folded position.

Fig. 5 is an edge elevation, viewed from the left, of Fig. l. f

F ig. 6 is an enlarged sectional detail taken on the line @h6 of Fig. 1.

Referring to the drawings, and first briefl describing the chair structure, 10 and 11 designate two pairs of supporting legs pivotally connected as by pivot bolts 12. The legs 10 arecontinuous with the upper frame part or back rest 13 as is common in folding chairs of this type. A cross bar 14: connects the legs 10 a slight distance above the pivots 12, 75 a cross bar 15 similarly connects the legs 10 below the pivots 12, and a similar' cross bar 15 connects the legs 11 adjacent to their lower ends; these cross bars functioning mainly as bracing and spacing members for the legs. A so panel 16 connects the upper portions of the side frame members of the back rest 13.

The seat as herein shown comprises an outer frame or rim member 17 and a seat board 18 suitably mounted in and held by the seat S5 frame 17. Each of the legs 11 has its upper end pivoted to theforward portion of the rim 17 of the seat, as shown at 19, and links 2O are pivoted at one end to the side frame members of the back rest 13 at 21 and adjacent 90 their other ends to the rear portion of the seat rim 17 as shown at 22. These links are each provided with an integral finger 20 which, in the unfolded position of the seat, strikes'the'crosslbar 1.4, as shown in Fig. 1, 95 and thus limits the unfolding movement of the scat, while in the folded position shown in Figs. 4 and 5, each .finger 20 strikes a lug 23 (Fig. 4) in the seat rim and limits the folding movement of the seat.

The chair may be folded by exerting a rearward pressure on the front of the seat and a forward pressure on the upper end of the back rest, the links 2O swinging on their pivots 21 upwardly until they lie parallel with the side frame members of the back rest, at the same time that the legs 10 and 11 swing into parallelism; and similar thrusts on the seat and back rest in the reverse direction readily unfolds the chair.

Coming now to a description of .the kneeler, attachment forming the principal subject matter of the present invention, 24 designates a U-shaped frame, the parallel limbs of which are pivoted at their free ends, as shown at 25 tothe lower portions of the legs 11 on the inner sides y of the latter. Mounted on and across the opposite end of the frame 24 is a pad or cushion 26. Pivoted at 27 to the side limbs `of the frame 24 beneath the pad 26 is a cross bar 28 that, as clearly shown in Fig. 4, has downwardly bent portions 28 thatform pad supporting legs,.these legs being preferably equipped with rubber feet 29. Pivoted to the bar 28 at 30 is a leg folding and unfolding link 31, the opposite end of which is pivoted at 32 to a lug 33 mounted on the cross bar 15.

The above described structure readily permits the kneeling stool to be folded to a position between the legs 11 and beneath the seat, as shown in Figs. 3,4 and 5, or to be drawn outwardly and downwardly to the service position illustrated in Fig. 1, and by dotted lines in Fig. 3. As the device is folded, the link 31 draws the bar 28 and its legs 28 to a position between the sides of the frame 24, as shown in Figs. 3y and 4, and during the unfolding movement of the kneeling device, the link 31 acts to swing the bar 28 and its legs 28 in an outward direction to form a support for the kneeling pad.

To save time and labor when gathering up and storing the chairs after use, I have provided a means for automatically folding the kneeling attachment at the same time that the chair itself'is folded. 'Describing vthis device, 34 designates each of a pair of links that are pivotally connected at their forward ends, as shown at 35, to pivot lugs 36 attached to the cross bar 15. At their rear ends the links 34 are pivotally connected at 37 to the forward ends of a pair of levers 38, which levers are pivoted intermediate their ends on the pivot bolts 25 by which the frame24 is jointed to the legs 11. 'llhe rear ends of the levers 38 are formed with U-shaped lateral extensions 38 adapted to embrace the parallel limbs of the kneeler frame 24. By reason of this construction, as the chair itself is folded, the links 34 and levers 38 are collapsed or folded, and this positively swings the kneeler frame 24 upwardly and forwardly to the folded position shown in Figs. 4 and 5. In this position the U-shaped lateral eX- tensions 38 hold the kneeler frame against falling outwardly. When the chair is again unfolded, the levers 38 swing away from the kneeler frame 34, as shown in Fig. 3, and the frame can then be left in folded position, or unfolded to service position, as circumstances may require.

To additionally lock the kneeler frame in its folded position and prevent it from falling. outwardly .when the collapsed. '.or folded chairv is being handled,l1 provide a yieldable locking device, best shown in Fig. 6, comprislingfa4 U-shaped spring locking clip 39, one limb of which is attached to each leg 11, while the other limb is adapted to have a `resilient bearing on theframe24. Preferably the inner side of the frame bar is formed with a slight depression 24 that cooperates withy aA protuberant lug 39 on the rfree limb of the clip 39. This suflices to maintain the kneeler frame in folded position, but permits the latter to be readily Vdrawn .out by a light pull on the pad. *The U-shaped clip 39 also serves to limit the inward movement of fthe kneeler frame and prevent strain onthe link 31 when the chair is in service position with the kneeler frame folded up, as 'shown by Vfull lines in Fig. 3.

From the foregoing it will be seen that my present invention provides a folding chair auditoriums and chapels where the ritual of the service may require the occupant attimes Y to assume a kneeling position, since it is -equippedwith a' kneeler itself attached to.

the chair and-readily foldable between idle and service positions and also, in the-form herein illustrated and described, automatically foldable when the chair itself is' folded and, in its folded position, lying substantially entirely between the planes of the front and rear sides of the chair. l/Vhile'l have shown and 'described one simple and practical mechanical embodiment of the invention,

itis manifest that the structural details,

thereof may be widely varied without involving any departure from the principle yof the inventionior sacrificing any of the advantages thereof. `Hence,'I do not limity Athe inventionto the specific embodiment herein 'presented for purposes of illustration,xbut reserve all suchV variations, modifications andV mechanical equivalents as fall' within thespirit and purview of the claims.
