SEAT.
Application filed September 27, 1926. Serial No. 137,886.
The present invcntion relates to swivel seats such as inay be used in'vehicle busses, or in i'ail cars, where it is necessary, Afii'equently, to reverse the position of any or all of the seats, as for example, when the direction in which the car travels is reversed, or when several people wish to face the scats so as to engage in conversation over an extended trip.v
In such cases it is desirable to rotate the seats with ease and also to secure them in a desired position without the necessity of manipulating certain mechanism designed to acconiplish such result.
An object of this invention is to provide a seat of the above type which may be rotated easily aiid wliich may be secured in any desired position, against casual inovement due to the inovement of the car or bus upon which it is mounted.
Referring to the accompanying forining a parthereof: i
Figure 1 is an elevation, partly in section, of a 'preferred form of my device.
Figure 2 is a plan view of the friction disc taken on line 2-2 of Ficfurel and looking drawings 2D in the direction of the arrows.
In the drawings, a represents a base provided at its lower extremity with'a flange a' and at its upper extreinity 'with a horizontal bearing surface m2. Projecting downwardly andl strengthened by webs aa is a Vertical bearing (L4.
An annular clamping jaw b engages an annulus of rubber or other yielding material o' which reccives the flange a' to seat it in a screws 52 secure the clampingl member to the floor.
A horizontal friction surface as is provided at the bot-tom of the bearing a4 and is engaged by a friction disc to be desci'ibed later.
The seat frame o is formed with a sub frame o' carrying a friction surface, or fiat 02, and a downwardly extending shaft C3. Bearing a* receives the shaft 03 and supports it with capacity for rotation.
A plate c* receives the thrust of the shaft 03 and is norinally held at its upper position, shown in Figure 1 by a spring 05 whichbalances the thrust due to the weight of the seat. Suitable means, such as boltc6 secures the plate o* to the shaft and between the two is provided a friction disc 07 secured to the plate c* by suitable means, such as rivets cs.
sonof its contact with the frictien surface (W under the pressure vexerted by spring G5.
. Vhen, however, a person sits in'the seat, or
suflicient pressure is eXerted there'on, the i spring' and seat are depressed and the disc o* disengages the surface a and the seat may be turned to any desii'ed position.
Changes maybe made in the design and arrangement of parts without 'departing from" the scope of the inv'ention as recited in the f appended claims.
What I claimis: 1. In a swivel seat, a base, a seat frame,
means vto mount the frame in the base rotat;
ably, means to receive the thrust of the seat when the latter is occupied, means independ ent of the last named means to exert a force upwardly against the frame to resist the weight of the seat, means to receive the thrust of the frame due to the force of said last Vnamed means, and fi'iction 'means disposed between the last Vnainedl thrust receiving means whereby the seat-.will be restrained from swivelling movements.
2. In a swivel seat, a base, a Vertical cylindrical bearing' formed in the base, horizontal surfaces on the base at the upper and lower extreinities of the bearing, a seat frame, a
downwardly' extending shaft on the seatl frame and carried-by the Vertical bearing in the base, a iane on the sha'ft to engage the upper surface of the base when the seat occupied, a disc secui'ed to the lower'end of the i shaft and adapted to engage the lower surface of the base, a spring seated by the disc and' normally ui'ging the seat frame upwardly and the disc into engagenient with the lower surface, and friction means between one of the surfaces and its cooperating portion of Vthe seat frame.
