EDWARD J'UBKOWSKI, OF NEW YORK, N. Y.
CHAIR-OPERATED AIR BL-AST.
Specification of Letters Patent.
Patented Nov. 24, 1914.
Application filed April 27, 1914. Serial No. 834,708.
To all whom it may concern:
Be it known that I, EDWARD JUnKowsKI, a subject of the Emperor of Austria-Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Chair-Operated Air-Blasts, of which the following is a specification.
This invention relates to new and useful improvements in chair operated air blast.
The primary object of this invention is to provide a device for automatically operating an air blast by means of the usual rocking motion of a rocking chair, the said blast being directed as desired by the occupant of the ch air.
A further object is to provide a rocking chair with a cooling medium for the occupant thereof and consisting of a blast aut0- matically operable by the rocking motion of the chair.
A still further object is to provide a rocker attachment adapted for actuating an air bellows when the rocker is is motion for supplying an air blast adapted to be directed as desired by the occupant of the chair.
With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.
In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :-Figure 1 is a side elevation of the rocking chair supplied with the present invention and portions of the same being broken away. Fig. 2 is a front elevation of the lower portion of the same, the operating rocker being shown in section and the front post of said rocker removed. Fig. 3 is a side elevation of the lower portion of the rocking chair showing the air bellows projected. Fig. 4 is a detail sectional view of the air blast pipe hinge, and Fig. 5 is a front elevation of the air blast nozzle.
Referring more in detail to the drawings,
the chair 10 is provided having opposite side rockers 11 and 12 and by means of which the occupant of the chair may rock backwardly and forwardly in the usual manner. The rocker 12 is provided with a substantially central enlargement l3 havingan inner chamber 14 for pivoting a lever 15 therein upon a transverse pin 16. The for ward end of said lever is provided with a roller 17 adapted to normally engage the floor such as 13 upon which the chair is adapted to rock. neath the chair bottom. support 20 and is provided with an operating lever 21 pivoted as at 22 to abracket 23 also carried by the support 20. The rear free end of the lever 21 is pivotally connected by a rod 24 with the slotted rear end 25 of the lever 15 while the spring 26 encircles said rod 24: and bears upon the upper surface of the rocker enlargement 13 and beneath a rigid abutment 27 carried by the said rod. An air outlet pipe 28 leads from the bellows 19 upwardly through the front post 29 of the chair to a tubular casing 30 in the upper end of said post. A valve plug 31 is journaled within the casing 30 and is provided with an angular port 32 therethrough adapted to be brought into and out of communication with the open upper end of the air pipe 28 as may be desired. An air blast tube 33 is secured to the valve 31 in communication with the port 32 thereof and said valve is adapted to be turned by manually moving the tube 33 either forwardly or rearwardly by the occupant of the chair. The top of the post 29 supports the chair arm 34: which is provided with a top opening 35 for accommodating the swinging of the air tube 33 which tube is adapted to lie flatly within the socket 36 of said arm when in its inoperative position as illustrated in dotted lines in Fig. 1 and at which time the valve 31 is closed. In said inoperative position, the curved portion- 36 of the tube 33is positioned in contact with the curved upper surface 37 of the lower wall of the arm socket 36 while the tube is retained upright as shown in Figs. 1 and 4 by engaging between the opposite membersof a spring clip 38 carried by the The air bellows 19 is mounted be-' front cross piece 39 of the said arm. The air blast tube 33 is provided with a hollow fiat end nozzle 40 provided with perforations 41 and whereby the air blast from the tube 33 may be directed as may be desirable by the occupant of the chair by imparting a swinging movement to the tube 33. I I
The operation of the air blast bellows 19 will be apparent from the present detailed description in that the spring 26 resiliently forces the rod 24 upwardly when the same is released by the roller end of the lever upon an upward movement of the forward portion of the rocker 12, as illustrated in Fig. 3 while a downward movement of the forward portion of said rocker forces the roller end of the lever 15 within the cham ber 14, thereby downwardly impelling the rod 24 thus contracting or closing the bellows and ejecting the air through the pipe 28 and tube 33, it being noted that such closing of the bellows closes the flap valve 42 over the air entrance port 43 of the bellows, while an opening of the bellows opens the valve 42 and admits airwithin the bellows for filling the same. With the tube 33 in its closed position within the socket 36 the air valve is closed and inoperative but when the tube 33 is positioned upright or substantially upright the valve port 32 is in communication with the bellows pipe 28, thus allowing the blast of air to be forced,
' through the nozzle perforations 41.
The usual rocking movement of the chair it will be seen will thus effect an opening and closing of the bellows 19 for forcing the air blast through the tube nozzle when the valve 31 is open, but as it may be desirable for rocking the chair without operating the bellows, a lever 44 is pivoted to the bottom support 20 and is provided with an end hook 45 adapted to span and engage the fixed collar 46 upon the rod 24 when the rod 24 is in its lowered position, as illustrated in Fig. 1, the said position of the lever being therein shown in dotted lines and at which time the lever 15 will be locked against movement within the chamber 14. When the lever 44 is released from the rod 24 the bellows will be again free for actuation.
It will thus be seen that an automatic bellows motor is provided upon a rocking chair for automatically supplying a cooling air draft to the occupant of the chair and operable at will during the usual rocking movement of the chair.
WVhile the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction without departing from the spirit and scope of the invention as set forth in the appended claims.
