Specification of Letters Patent.
Patented Apr. 22, 1919.
Application filed November 7, 1917. Serial No. 201,168.
To all whom it may concern:
Be it known that I, PAinnsH BARKER, a citizen of the Unitedistates, residing in the city and county of San Francisco and State of California, have invented anew and useful Direct and Ilaterally Leaning, Rocking, Firm-Standing, and Pivotal Chair, ofwhicli the following is aspecification.
An object 0ft my invention is to provide a novel rocking chair. Aiurther object is toprovide a rocking chair having, functions in addition to those-of rocking chairs of former construction in that the occupant may not only rock directly back and forward when he chooses so to do, but he may also atwillirock the chair into a sidewise leaning position, andmay at Wlll'I'OOk backward and forward in any of said positions, and may at willisit with the chair; stationary in either an-erect or in a sidewise leaning position.
An object is to provide a rocking chair which the occupant can adjust to various comfortable changes of position, erect or leaning to one side or the other in order to rest the body or in order to draw close to or move away from a reading lamp or a sewing table, without rising, andtoallow the person to rock comfortably in any, of the various positions;
The invention is regarded as broadly new, basic, and pioneer, in that it is constructedwith rocker treads of different arcs, the axes of-which are in angular relation to each. other, so that the chair may rock or stand in either an upright position or with an inclination toone or the other side at the pleasure of the occupant; and also in that it! haslrocher meansthat form a pivotal support.
The invention risfregarded as; broadly new, basic and pioneen in that! it has rocker; treads constructed practically asthe arcs of various cylinders the axes of. which arcs areiin angular relationito each other, thatis tosay, assuming the; chain to stand normally up right, the front portionsiof the supporting the side rockers being ribs bent upwardiat the rear and constructed in combination with the treads ofintermediate rocker means that respectively conform to the arcs of two cylinders respectively which are constructed from axes that are oblique to the axis of the forward arc and to each other.
In practice various forms of this novel rocking chair may be constructed andi I shall illustrate the same in two of said forms.
The invention is capable of being carried out with either one supplemental or intermediate rocker or with more than one supplemental or intermediate rocker.
An object is to provide a rocking chair adapted to a variety of novel rocking and standing positions.
It is understood that the rocker treads are not exactly constructed to the arcs of cylinders and the term practically cylindrical is intended herein to indicate such approach to or departure from the cylindrical form, as may be deemed expedient by the constructor.
It is not an object to change the form of the supporting tread of the rockers, except asimay be necessary to allow the chair to assumethe erect and leaning positions alternately.
A further object is to enable the seated occupant to easily turn the chair around pivotally without rising.
Other objects, advantages and features of novelty may appear, from the accompanying drawings, the subjoined detail description and the appended claims.
The accompanying drawings illustrate the invention.
Eigureil is a typical. side elevation of a rocking chair embodying this invention and in erect position for rocking directlyforward andback as a: common rocking chair. Broken lines indicate a tilted position of said a chair.
Fig. 2 is a rear elevation of a chair of the quadruple rocker form in the erect position showninsolidlines in Fi 1.
Fig. 3 is a perspective ske eton View of the lower frame of thet quadruple rocker chair viewed from above at the rear.
Fig. 4 is a rear sectional elevationshowing in 395812111185 the quadr ple. rocker, chair rocked directly back; and showing in broken lines a position of the rocker and the chair tilted to the right.
Fig. 5 is a view analogous to Fig. 3 showing' the construction with a. single central chair-tilting rocker.
Fig. 6 is an enlarged typical fraginental side view of the rocker of any of the foregoing views in the erect position.
The chair comprises a box 1 having front legs 2, 3, mounted on forward rocker por tions 4-, 5, and having rear legs 6, 7, mounted upon upwardly deflected rear rocker portions formed by ribs 8, 9. The rocker portions 4;, 5, 8, 9 constitute side rockers. Said side rockers are connected by a brace or stretcher 10. The frame 1 has a rear cross piece 11. Intermediate rockers formed by ribs 12, 13 in the form shown in Fig. 3 are connected by suitable means as the screws or dowels 14 to the brace 10, and are connected at 15 to the rear cross piece 11 of the frame.
In the form shown in Fig. 5 a single intermediate rocker, 16, is shown, and this extends directly back along the midline between the side rockers.
By means of the side rockers and the intermediate rockers, the rocking chair is provided with various rocker treads constructed in various arcs drawn to axes that are in angular relation to each other. The front tread 17 constituted by the bottoms of the forward portions 4:, 5, of the side rockers, is drawn to an axis, not shown, parallel to the front cross piece 18 of the frame 1; that is to say, the transverse traces of the forward tread are horizontal when the chair is upright.
The normal bottoms 19 of the intermediate rocker means of either form of chair shown constitute a rearward continuation of the same tread, so that while the chair is in an upright position as indicated in solid lines in Figs. 1, 2 and 4, the chair may be rocked backward and forward to the fullest extent the same as with an ordinary chair, the chair at its forward position bein sustained by the direct tread 17 of the side rockers, and in its backward position bein sustained by the direct tread 19 of the in ermediate rocker means shown either at 12, 13 or at 16. The side rockers, however, are provided with upwardly deflected rear sections having tread faces 20, bein the bottoms of the rear portions 8, 9 and adapted to form with the bottom faces 19, rear lateral treads each drawn to an axis, not shown, that is horizontal when the chair is inclined and aslant as indicated by dot-and-dash lines 21 in Fig.
4 when the chair is upright. By this construction, when the chair is supported by a lane surface 22 it may be rocked directly orward and back on the combination tread formed by the are 17, and the rearward extension 19 thereof; and when the occupant so desires he may throw his weight to one or the other side of the rocking chair as he rocks back, and as the chair leaves the are 17 of the forward tread the chair will be caused to take its support from a tread formed by the side are 20 combined with an intermediate are 19. The chair is thus tilted sidewise in the rear rocking position indicated by the dot-and-dash lines in Fig. 4.
As a consequence of the construction hereinbefore described, the occupant of the chair is able to easily bring his body to erect position either rocking or stationary or to in clined position either to the right or left, and either rocking or stationary as may be most comfortable for the time being.
The crowns a, a of the side rocker means 8, 9 and the crowns b, b of the supplemental or intermediate rocker means 12, 13, are oil's-ct front and back, relative to each other, so as to practically form four feet intermediate the front and back of the chair when the chair is in the upright position shown in Fig. 1. The two crowns b, b of the intermediate rocker means 12, 13, in Figs. 1 and 3 are so close to each other and to the vertical axis of the chair body, that they practically form a central pivotal support which gives the effect of one foot of a tripod of which the crowns a, a are the other two feet. This central foot practically formed by these two central rocker crowns D, b co-acts with the widely separated side rocker crowns a, a to give a three-footed non-rocking stable or firm-standing support for the chair when upright; so that the chair in its central upright position affords comfort to a erson desiring to sit steadily upright wit out rocking.
The crown b" of the central rocker 16 shown in Fig. 5 affords a like support when desired. This non-rocking or firm-standing character is changed by tilting the chair back or forward; and when the chair is tilted back the intermediate rocker means 12, 18 will act as is the case with common rockers for rocking directly back and forward; and, since the tread of the intermediate rocker means widens rearwardly in the formshown at 12, 13 in Figs. 1 and 3, the farther back the rockin chair of that form is rocked, the more positive is the support of its active rocker means or tread against any lateral tilting or leaning.
The lateral tilting or leaning of the chair is easily eflected by the occupant by simply first bringing the chair to the upright position, and there simultaneously leaning to one side and tilting back. The chair is thus made to lean and may be rocked to and fro at will; or may be brought to rest in the leaning and tilting position.
By returning to the stable position and then rocking back somewhat so that the naeaeec chair is supported by only the central pivotal foot formed b the two intermediate rocker crowns b, b i Figs. 1 and 3, the chair may be rotated as on a pivot.
A like position with the form 'shewn in Fig. 5 allows the chair to pivot on crown b" I claim 1. A rocking chair having its rocker tread constructed of ribs in various arcs drawn to axes that are in angular relation to each other at front and back of the tread.
