corporation of Illinois Application June 17,
This invention relates to a revolving seat and more particularly to a revolving seat-support. The invention is especially useful in connection with transportation seats.
An object or" the invention is to provide a revolving seat, suitable for railway cars, buses, and other transportation uses, in which the parts are reduced to a minimum and in which the main parts may be readily separated when desired. A further object is to provide a seat-supporting structure of extremely simple construction in which interchangeable parts may be used to adapt the support for seats of varying sizes. Other specic objects and advantages will appear as the specification proceeds. y
The invention is illustrated, in a preferred embodiment, by the accompanying drawing, in which- Figure l is a plan View of a seat-supporting structure embodying my invention; Fig. 2, a side view in elevation; Fig. 3, a transverse sectional view, the section being taken as indicated at line 3 of Fig. 2; Fig. 4, a broken detail sectional View, the section being taken as indicated at line 4 of Fig. 1; and Fig. 5, a broken sectional detail View, the section being taken as indicated at line 5 of Fig. l.
In the illustration given, A designates a base member; and B, a rotatable member carried by member A.
The base A may be of any suitable construction. I prefer to form it of aluminum alloy because of the lightness of the structure, although other suitable m'etal may be employed. In the illustration given, the base A is provided with a base flange I0 which may be bolted to the bottom of a car. Integrally formed with base flange I0 is a cylindrical flange or neck l I. Integrally formed with neck I I at its upper side is a wide horizontal ange I2. A series of spaced ribs I3 are formed integrally with the neck I I and flange I2 to form supports for the flange I2. On its inner side, the neck II is preferably cut away at I4 to provide a space between the member A and the rotatable member B.
The rotatable member B may also be of any suitable construction. It is preferably formed of a heat-treated aluminum alloy, but any other suitable metal may be employed. The member B is provided with a deep tubular neck I5 which is telescopically received within neck I I of base A. The tubular ange or neck I5 is also cut away on its outer side at I6, as shown morey clearly in Fig. 5, so as to provide with the cut-away portion I4 of neck II a space between the parts II and 1935, serial No. 27,091
I5, thus reducing the contacting area between the parts. The member B is also provided with a horizontal flange il resting upon flange I2. Flange l? is' cut away on one side to provide shoulders I8. as shown more clearly in'Fig. '1,
adapted to engage the lug I9 carried by flange I2. 'The cut-away portions about the periphery' of flange Il and between shoulders I8 permit the rotatable member B to. 'be rotated throughfthe arc 0I" a half circle. k n Seat-supporting arms 2S, are carried byy Elle rotatable member B; The arms may be of different lengths to support Jdierent sized seats. lPreferably,the arms are constructed asushown more K clearly in Figs.. l, 2 and 4..k As shown'moreclearly in Fig. 4, each arm 2i! is providedy withvagflat downwardly to form a segmental ange '22'which is received within flange I5 of member B. The horizontal flange portion 2i is inclined upwardly as it extends beyond ange I'I to provide an inclined wall 23. The inclined wall 23 terminates in a horizontal circular support 24 which isl perforated to receive a bolt (not shown) by which the arm may be secured to a seat structure. To reinforce each of the arms, I provide a vertical flange 25 which runs centrally along iianges 2| and 23, as shown more clearly in Figs. 1 and 2. 'Ihe anges 2l and 22 are secured to the neck I5 and ange of member B by removable bolts 26 as shown more clearly in Fig. 4.
Any suitable locking means for releasably connecting the rotatably related parts of the structure may be employed. In the illustration given, the neck II of base A is apertured at 21 to receive locking pin 28. Theinner tubular member I5 of member B is provided with a pair of apertures 29 through which pin 28 may extend. The locking pin or bolt 28 is housed within a tubular casing 3G which is provided with a circular flange 3l bolted to thecircular ilange II. vA spring 32 is housed within the casing 36 kand extends about a reduced end portion 33 of bolt 23. The lower side of casing is provided with a slot 34.
To reciprocate the bolt 28, I provide a treadle member 35 which is pivotally secured to a lug 36 carried by the circular flange I I and a bell-crank I enables the operator to conveniently swing the bolt in and out of locking position.
In the operation of the device, assuming that the parts are in the locked position shown in Figs. 3 and 5, and it is desired to reverse the position of the seat, the operator places his foot on treadle flange 40 and thereby retracts bolt 28 from engagement with opening 29 of the circular flange I5. The rotatable member B may then be swung about in a semi-circle, the pin or bolt 28 riding against the outer periphery of flange I5. The engagement of lug I9 with shoulder I8 causes the rotation of the seat to stop when it is fully reversed and at the same time, pin 28 automatically slips into opening 29 under the pressure of spring 32. When it is desired to remove the seat in order that the cushion parts, etc. may be cleaned, it is only necessary for the operator to depress treadle and then lift the seat structure with rotatable member B away from the base structure A. Thus in a very brief time, the seats within a railway car may be removed, leaving only the base structures in the car. New seats can be readily installed in place of the removed seats if desired, it being necessary only to withdraw pin 38 by pressing on treadle 35, while the neck l5 of the rotatable member B is dropped within circular flange H. If it is desired to support a larger seat structure or a seat structure of a diierent shape upon rotatable member B, this may be readily accomplished by removing the supporting arms 2D and replacing them with supporting arms of different lengths.
The new structure eliminates a large number of parts formerly thought necessary for a seatsupporting structure, while providing a sturdy construction of extremely few parts, the main parts of which may be readily separated or interchanged.
While I have shown by way of illustration a specific structure, it will be understood that changes can be made with respect to many of the details thereof without departing from the spirit of my invention. The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims `should be construed as broadly as permissible, in view of the prior art.
1. A revolving seat-support comprising a base equipped with a tubular ange and a horizontal flange at the top of said tubular flange, a rotatable member having a horizontal flange resting on said first-mentioned horizontal flange and a tubular flange received within said first-mentioned tubular flange, and seat-supporting arms having their inner ends turned downwardly, said arms being secured both to the top side of the horizontal flange and to the inside of the tubular flange of said rotatable member.
2. A revolving seat-support comprising: a base having a tubular ange and a horizontal flange at the top of said tubular ange; a rotatable member'having a horizontal flange resting on said rst mentioned horizontal flange and a tubular flange received within said rst mentioned tubular flange; and seat-supporting arms including iiat bottom flanges having their inner ends turned downwardly and including also vertical anges extending longitudinally of the arms and above said bottom flanges, said bottom flanges being secured both at the top side of the horizontal flange and to the inside of the tubular flange of said rotatable member.
