Specification of Letters Patent.

Patented July 11, 1222.

Application filed .Tune 12, 1920. Serial No. 388,619.

To all whom it may concern:

Be it known that i, THOMAS E. JORDAN, a citizen 'of'the United States, residing at Malden, county of Middlesex, State of Massachusetts, have invented an Improvement in Seesaws, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to see-saws and has for its object to provide an improved seesaw having the novel features hereinafter set forth.

In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.

Fig. 1 is a side view of a see-saw embodying my invention;

ig. 2 is an enlarged sectional view on the line 22, Fig. 1;

Fig. 3 is a View on the line 33, Fig. 2.

Fig. a is a section on the line l-a, Fig. 2.

My improved see-saw comprises a stand or support 1 on which is pivotally mounted a beam 2 having seats 3 at the ends thereof. The stand 1 is pyramidal in shape, and it comprises four angle-iron legs 4: which are inclined to each other and to the floor, and all of which are fastened at their upper ends to a head-piece 5. The legs 41; are connected at their lower ends by the cross-pieces 6. The head 5 is cap-shaped, is rectangular in cross-section, and has the four sides 26 arranged with the opposite sides inclined relative to each other and with adjacent sides at right angles to each other. The upper ends of the angleiron legs 4 are set within the cap 5 with the angles resting against the sides thereof, and said legs are secured to the cap by any suitable means, such as bolts, screws, or rivets 7. The cap-piece 5 carries a fulcrum member 8 on which the beam 2 fulcrums. This fulcrum member has the fulcrum edge 9 and the two sides or arms 10 that embrace the sides of the beam 2. It is also provided with the cylindrical stem 11 which fits an opening in the top of the cap 5. This fulcrum member can, therefore, turn in the cap 5, thus giving a swivel connection between the beam and the stand.

The beam is of novel construction, it being made relatively narrow so that the persons using the device can occupy the seats 3 with comfort, and it also being made so as to give it all the required strength. I propose to make the beam of channel iron with the channel directed downwardly, as shown in Fig. 2, and then to fill the channel iron with a strip 12 of wood. The channel iron gives the necessary strength to the beam, so that it will support the weight on the end without bending and by filling the channel iron with a wooden strip 12, any tendency of the channel iron to twist or warp is obviated. The under edge of the channel iron is provided with a plurality of notches 13 to re ceive the fulcrum edge 9. One of the notches is placed at the center of the beam and others at one side of the center, so that by properly shifting the beam relative to the fulcrum member, the arms of the beam may be given the proper relative length so that persons of different weights will be evenly balanced.

I will preferably provide a pair of handles at each end of the beam to be grasped by the occupant of each seat 3. The handles are indicated at 14C and they are secured to a U-shaped bracket 15 which in turn is secured to the beam. The bracket is provided with the portion 16 that embraces the beam and is fastened in place by the screw or bolt 17.

I claim:

1. A see-saw comprising a pyramidal standard having a four-sided cap member arranged with adjacent sides at right angles to each other and each side inclined outwardly and downwardly, and angle-iron legs having their upper ends inserted within the cap member at the corners thereof so that each flange of each leg bears flatly against one side of the cap member, means securing said legs to said cap member, and a channel-iron beam member fulcrumed on said cap member and provided at its ends with seats.

2. A see-saw comprising a pyramidal standard having a four-sided cap member arranged with adjacent sides at right angles to each other and each side inclined outwardly and downwardly, and angle-iron legs having their upper ends inserted within the cap member and secured to the sides thereof, and a channel-iron beam member fulcrumed on said cap member and arranged with the channel directed downwardly, said channel being filled with a strip of wood, and seats at the end of the beam member.

3. In a see-saw, the combination with a stand, of a fulcrum member having a shank or stem swiveled in the stand and provided with a fulcrum edge, and two arms extending upwardly at each end thereof, and a channel-iron beam member received between said arms and fulcrumedon said fulcrum edge.

4. A see-saw comprising a pyramidal standard having a four-sided cap member arranged with adjacent sides at right angles to each other and each side inclined outwardly and downwardly, and angle-iron legs having their upper ends inserted within the cap member at the corners thereof so that each flange of each leg bears flatly against one side of the cap member, means securing said legs to said cap member, and a channeliron beam member fulcrumed on said cap member and provided at its ends with seats, said channel iron being filled from one end to the other with a strip of wood.

In testimony whereof, I have signed my name to this specification.

THOMAS E. JORDAN.
