SEAT PEDESTAL Filed April 4, 1955 United States Patent @fiice iatented May 27, 1958 SEAT PEDESTAL Carl T. Swenson, Milwaukee, Wis., assignor to Milsco Manufacturing Company, Milwaukee, Wis., a corporation of Wisconsin Application April 4, 1955, Serial No. 498,977

1 Claim. (Cl. 155-90) The invention relates to seats and more particularly to a pedestal mounting for a seat.

The main object of the invention is to provide a seat supporting pedestal of simple and rugged construction having means for varying the effective height of the pedestal and means for varying the angular relation of the seat relative to the pedestal.

The invention further consists in the several features hereinafter set forth and more particularly defined by claim at the conclusion hereof.

In the drawings:

Fig. l is a side elevation view of a seat pedestal embodying the invention;

Fig. 2 is a front elevation view of the seat pedestal, parts being broken away and parts being shown in section;

Fig. 3 is a detailed horizontal sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a detailed horizontal sectional view taken on the line 4-4 of Fig. 2.

Referring to the drawings, the pedestal includes a hollow metal post 5 mounted on a base plate 6, a hollow metal post 7 adapted to telescope within the post 5 and a seat mounting carried by the post 7.

The post 5 is reinforced at its base by a pair of metal plates 8 (one being shown) welded to the sides of the post and the base plate 6. The post has a series of lengthwise spaced diametrically disposed sets of holes 9, in any one of which a height adjusting bolt 10 may be mounted to form a support for the post 7 which has diametrically disposed notches 7a (one being indicated) at its lower edge to engage said bolt.

The seat mounting includes a square metal plate 11 provided with holes 12 for the reception of bolts 13 secured to the seat 14. The plate 11 has a hinge plate 15 welded to the bottom thereof and formed at one side to provide hinge ears 16 at the end thereof and a centrally disposed hinge ear 17.

The top of the post 7 has a fiat metal plate 18 welded thereto and to which a flat hinge plate 19 is welded, said plate 19 being formed at one side to provide spaced hinge ears 20 that fit between the ears 16 and 17. A headed hinge pin 21 passes through the alined ears 16, 17, and 20 and is held in position by a cotter pin 22. Thus the seat can tilt relative to the post 7.

To hold the seat in various angular positions the seat plate 11 has a pair of sector members 23 secured thereto on opposite sides of the posts 5 and 7. These members 23 are provided with a series of alined circumferentially spaced radial notches 24 adapted to be engaged by the transverse portion 25 of a U-shaped dog 26 whose leg portions are pivotally mounted on a pin 27 mounted in diametrically disposed holes in the post 7. The dog is normally urged into locking engagement with the sector members 23 by torsion springs 28, each spring 28 having one of its ends anchored in the post 7 and the other hooked onto a leg of the dog. For releasing the dog, a rod 29 is welded to the front of the transverse portion 25 of the dog and extends outward to form a bent up handle 30.

With the above construction, the seat may be adjusted to the desired height by placing bolt 10 in a seelcted pair of the holes 9, and then if the operator desires to change the position of the seat as shown in Fig. l where the dog 26 is engaging the first set of notches 24, he may release the dog and swing the seat on its hinge pin 21 to bring the dog 26 in alinement with any one of the other sets of notches and tilt the forward edge of the seat downwardly and then allow the springs 28 to swing the dog into engagement with the selected alined notches.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the'claim.

What I claim as my invention is:

In a seat pedestal, the combination of a post, a post mounted for lengthwise vertical adjustment relative to said first named post, a seat mounting plate, a hinge connection between said plate and the top of the vertically adjustable post, a pair of sector members secured to said mounting plate and provided with alined sets of circumferentially spaced radially disposed notches, said sector members straddling the adjustable post and depending below said mounting plate, a U-shaped dog member pivotally mounted on said vertically adjustable post and adapted to engage any one set of said notches to hold said mounting plate in the desired angular position relative to the posts and having a rod secured to its transverse portion and extending outwardly to form an operating handle, and spring means urging said dog to a notch engaging position.
