Application filed December 1'7, 1914 Serial No. 877,765.

To all whom/it may concern Be it known that I, FIORE RICCIARDELLI,

a citizen of the 'UnitedStates, residing at Jersey City, in the county of Hudson and State of NewJ'ersey, have invented a certain new and useful Improvement in Chairs, of which the following is a specification.

The object of my invention is to providea chair which w1ll always present a cool,-

sanitary seat to one desiringto occupy the chair. After a chair has been occupied any considerable time the body heatsithe seat: rendering the occupancy of the chair immediately after its vacation uncomfortable,

and sometimes, perhapsycausing or aggravatlng disorders. I ZilSO'PIOVM-IG a chair the back of which may always be kept cool. and comfortable.

While I haveshown and described a barbers chair embodying my invention, I desire of the chair illustrated in Fig.1; 8 is an elevation of the back ofthe chair illustrated in Fig. 1; Fig. 4 is a side elevation arms are supported at their rear ends by knuckles D hinged at (Z to web pieces A of the frame A. The pieces'A are shown as also hinged at cl to rear standards I3 fastened to the seat frame D and E designate rods shown as pivoted to the front standards D at e. The rods E are shown as hinged to the front knuckles D at c. foot rest of any desired construction may be attached to the lower ends of the rods EL It has been found desirable to so construct illustrate and describe such a head rest B is shown as barber chairs that the backs thereof may be I adjusted at any desired angle, that the seats thereof may be raised and lowered, and that the body of the chair may be revolved.

The movement of the chair back backward draws backward with it the arms; and this carries backward the upper ends of the rods E, thereby causing an upward movement of the lower ends of therods E and of the foot rest attached thereto. As, however, the ad connected therewith and means for locking the chair back and parts connected there with in any desired position and for releasing the chair back and parts connected therewith from any position in whichthey may be locked; form 110 part of my present 1njustment of the chair back and of the parts vention I have not thought it necessary to illustrate or describe such means.

Any suitable mechanism may, ofcourse,

be employed to' raise and lower the chair seat, but as such mechanlsmforms no part of my present invention I have omitted to mechanism. For the same reason-I have omitted to illustrate'or describe means for permitting the body of the chair to be revolved on the base G. I

H designates a chair back shown as pivoted in the frame A at it, and 72,- designates a handle by which the chair back H may be turned. The chair back I-I is shown as provided wlth recesses ha ha 111 its upper and lower ends respectively.

I designates a bolt shown as provided with a handle i. The upper end of this bolt is shown as provided with a head i, and a coiled spring 2' is shown as. seated in the seat frame D 'and has bearing against the head 2'.

latter stands at its usual position as seen in that view or is inclined farther to the rear as 1s sometimes desired. In that case the back frame and back swlng around the centeroZ and the lower edge of the back of course descends toward the'seat frame, but

the spring 2' under the head of the bolt I permits the descent of the tip i so that the latter does not need to be disengaged from that it stands practically tangential to an are drawn around the center 01 and through the lowermost recess which is h in Fig. 6,

and this factin addition to the looseness of the tip within the recess and the pivotal mounting of the back in the back frameprevents the parts from binding while the back is swung to the rear some little distance. Of course if it is to be swung to the rear into nearly a; horizontal position, as often occurs'when the barber is shaving his customer, it will be necessary to disengage the bolt from the socket before swinging the back to such an extreme. I This can be accomplished by depressing the handle z' so as to draw the head of the bolt and its tip well'down intogthe socket in the seat frame (best seen in Fig. 6), after which the back frame may be swung to the rear as far as possible and as the. construction permits, and they lower edge of the back will then rest upon the rear cross bar of the seat frame. as will be clear;

J designates a chair seat shown as pivoted in the seat frame D at j, and 'y' designates a handle by which the chair seat J maybe turned. The chair seat J is shown as provided with recesses 1' 7' in itsrear and front edges respectively.

In Fig.2 K designates a bell crank lever fulcrumed at is and provided with a handle is, A'bolt 70 may be made integral with or secured to this bell crank lever K and a spring 76 is shown as bearing'against the bell crank lever K to press the bolt forward through an opening in the seat frame into the recesses 3' 7' A latch L is shown pivoted at Z, and a spring Z is shown as pulling the lower end of thelatch forward to throw its beveled tip normally into the recess which is at the front at that time. It will be observed from Fig. 2 thatthe bevel is onthe under side of the tip, and therefore the straight face of this tip positively supports the front edge of the seat J and the weight of the person thereon, even though the bolt at the rear should be retracted; The use of this tip makes it necessary in reversing the seat to raise its front edge and turn it over to the rear.

The seat frame D is shown as aflixed to a support asM. This support M is shown as .soshaped as to permit the chair seat J being turned therein.

In Fig. 7 I have shown another form of bolt. This is a plunger N provided at one end with a knob or handle n and as encircled by a spring n, one end of which is shown as resting against the frame D and the other end of which is shown as resting against a collar 01? made integral with or secured to the plunger N. The end at of the plunger N will, of course, be so shaped as to fit into the recesses j 3' To reverse the chair back H the bolt I may be pulled down to draw the pin i out from the recess 71, and the chair back H may then be turned either by pushing the chair back H around or by turning the handle it. When the chair back 11 has been turned around sufficiently the recess 71, will present itself to the pin 2' and the spring 7? will force the pin 2' into the re cess 7%, thereby locking the chair back H in position.

To reverse the chair seat J the handle Z7 may be pulled down in the direction of the arrow, Fig. 2, and the bolt 76 thereby with drawn from the recess f. The chair seat J may then be turned either by pushing it around or by turning the handle j. By pressure on the rear of the chair seat J or by turning the handle 7' in the proper direction the front of the chair seat J will rise and the latch L will be thrown out of engagement with the recess j Vhen the chair seat J has been turned around sulliciently the latch L will engage the recess 7' and the bolt 10 will engage the recess j and the chair seat J will thereby be locked in position.

The plunger bolt N (Fig. 7) may, of course, be used instead of the bell crank lever K and bolt 7: (Fig. 2).

What I claim as my invention and desire to secure by Letters Patent is:

The combination with a frame for the seat of a chair of a seat portion pivoted therein, said frame having an inwardly extending flange adjacent to one side of the seat and having an outwardly extending flange along a side opposite the flange first mentioned, said outward flange extending rearwardly, and then downwardly to form a space between the flange and the frame, a pawl extending through an opening in the frame engaging one edge of the sent, an angular member pivoted to the frame and having one end connected with the pawl, the opposite end of the angular member extending outwardly below the free edge of the flange, a spring between the edge of the flange and the angular member, and a second pawl pivoted below the flange on the opposite side of the frame for engaging the seat portion at that point.

FIORE RICCIARDELLI.
