\ P. F. HEARSCH EASY CHAI R Filed Aprily 2, 1923 Patented Sept. '30, 1924.
PERHAM F. HEARSCH, OF SEATTLE, WASHINGTON.
EASY CHAIR.
Application filed April 2, 1923.
To all whom t may concern.'
Be it known that I, PERHAM F. HnARscI-r, a citizen of the United States of America, and resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful lmprovements in Easy Chairs, of which the following is a specification.
My invention relates to easy chairs and consists of a chair in which the seat and back are pivoted to swing about a pivot located towards the forward edge of the seat, and in which said seat and back `are spring supported so as to normally have a relative- .ly small angle of swing under the weight. of
a person of average weight, and which is, however, provided with means so that an increased angle of inclination can be given the seat and back by the positive application of power thereto throughamember engaged by the foot, whereby the chair may be permanently locked in such increased angle of inclination when desired.
The object of my invention is to provide a chair having a pivoted back and seat, with means of simple character whereby the swinging of the chair through an increased angle may be conveniently done where the weight of the person is not alone sufficient to cause this increased swing.
The features of my invention which I believe to be new will be hereinafter described and then particularly defined in the claims.
The accompanying drawings show the type of construction which I now prefer to use in carrying out my invention.
Figure l is a side view of the chair showing the face of the basewhich is towards the observer as being removed so as to show the mechanism for operating the chair.
Figure 2 is a similar view showing the chair in its inclined position.
The chair is provided with a base as l, which is or may be of any suitable type of construction, and a seatand back9 2 and 20, which it is designed shall be of such integral construction that there is no relative movement between these parts. The seat and back are pivoted to swing about a pivot axis represented at 12. Under the rear edge of the seat, springs as 3 are shown which are supported at theirlower edge upon a bar or bracket as 30 carried by the base and engaging the rearmost part of the seat. These springs are designed to be sufficient in Serial No. 629,246.
number and in strength to support a person of at least average weight wit-hout being depressed too much for comfort. It is, however, designed that the chair be capable of swinging backward and downward somewhat more than would ordinarily be desii-ed, as when a person desires to recline in position of rest. l have provided means whereby the seat and back may be swung to an angle which is greater than that which follows from the weight of the occupant, whenever such increased angle is desired. This mechanism is one which is positively operated by engagement of the foot of the occupant.
Pivot-ally carried upon the chair base is a bell crank lever or levers 4. One of these may be mounted at each side of the chair. @ne arm of this lever' is connected with the seat by means of a link as 5, which link is also pivotally connected with the seat base as at 5l. The connection between the bell crank lever and the link or the connection between the link and the seat, should be of such. character that the seat may be depressed as much as would ordinarily occur by the weight of the occupant, without requiring any movement of the bell crank lever. This is shown as accomplished by having the pin 52 carried by the lever, passing through a slot 5() in the link so that downward movement of the link will not cause any swinging action of the lever until it has passed through a considerable distance. At the same time, if power be applied to the lever to swing it, it will positively transmit this power to the seat.
To the other arm of the lever 4 is connected a bar 6 which bar is provided with notches as making a ratchet bar of it, and these are engaged by a pawl 61 pivoted upon the sides of the base. This pawl has a rod as 62 connected therewith and extending up at the side of the chair where it may be conveniently enga-ged by the occupant. By lifting this rod 62 the pawl is disengaged from the ratchet bar 6.
A guide for this ratchet bar is provided, preferably close to the forward edge of the base. rFhis is shown as consisting of a plate 7 which has its ends secured to the side of the base and is centrally bowed out sufficient to pass the ratchet bar 6. Beneath this plate 7 is preferably mounted a small roller 70 whereby the friction of the bar 6 in passing through the guides is reduced.
not depress it as tar as may be desired, the board 8 may be swung down into the position shown in Figure 2, and the toot or shoe of the occupant may be engaged by a cross bar 81 which is carried by the said board in somewhat raised position. By pushing outwardly upon this, power may be applied to the seatthrough the ratchet bar 6, bell crank lever 4f and link 5, so as to additionally depress the springs 3 and secure a farther back- 4ward and downward swing to the back and seat.
What I claim as my invention is:
1. A chair having a back and seat swinging about an axis located near the front edge of the seat, springs holding th-e seat raised, a rod mounted in the base for reciprocation from front to rear, means connecting said rod with the seat to lower itand a board f pivoted upon said rod to normally form a section of the front of the chair base, said board having upon its inner face a raised bar adaptedwhen the board is swung down to be engaged by the feet to thereby pull down the seat. y u
2. A chair having a base, a seat hinged near its front edge, seat supporting springs beneath the rear edge of th-e seat, a bell crank lever pivoted upon the base, av link connecting an arm oit said lever with the seat and having a sliding connection permitting tree` downward movement of the seat, a ratchet Vbar connecting with the other arm ot the lever, a holding dog, and a member carried by said bar and engageable by the foot 'for drawing out said bar to therebyy pull down the seat.
Signed at Seattle, King County, Wasl -v ington, this 24th day of March 1923.
PERHAM F. Hansson.
