SLED.

Application filed July 9, 1923. Serial No'. 650,373.

To all 'whom it 12mg/ cwwam: l

Be it known that I, Im: L. ROBBmm, a

citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Sleds, of which the following is a specification.

This invention relates to sleds, and has for its leading object thel provision of a device which will serve to add to and increase the springiness of a coasting sled, whereby the sled will have considerably more elasticity and spring in its action when taking bumps or bounds than is-present in the ordinary type ofcoasting sled.

A further object of the present invention is the provision of adjusting means whereby the springiness or elastic action of the seating arrangement may be adjusted and regulated within certain limits.

A further object 'of the invention is the provision of a device of this character in which the parts shall be so related that the elastic or spring action of the sled may be increased or decreased within certain limits and av sport toyA provided having characteristics not possessed by prior devices.

Other objects and advantages of the invention should be readily apparent by reference to the following specification take-n in connection with the accompanyin drawings, and it will be understood t at any modifications or departures may be made from the specific features disclosed within the scoIe of the claim without 'departing from or exceeding the spirit of the invention, a preferred form only of the device being shown for sake of and by way of illustration.

Figure I is a perspective view of the in vention, showing the forward end of the runner flexed or bent up by the weight of the user.

Figure II is a side elevation of the 1nvention showing in dotted lines the spring action of the same.

Figure III is a partial longitudinal cross vsection on line III-III of Figure I.

Figure IV is a cross section on line IV-IV of Figure II.

Referring to the drawings, 1 is a base or runner board, which is straight, as shown in dotted lines in Figure II, whenrelieved of the riders weight, but has an upturned or sprung-up forward portion 2 when in use.

Intermediate the ends of the base or runner board are slide supports 3, in which is held the seat pedestal 4, which is secured in the guides 3 4by any suitable arrangement so 60 that the base pedestal 4 may be locked in any position intermediate the ends of the guides 3, as desired, as shown in 'Figure III.

he pedestal 4 is secured to the top or-seat board by the bolts 7 but the pedestal 4 is G5 not locked to the base or runner board 1 but is free to slide inthe guides 3 both longitudinally and up and down, the guides 3 being of a height suiiicient to prevent the pedestal 4 from jumping out from between 70 the guides 3 when the sled is being used with someone on the seat. The pedestal 4 is held by the guides 3 from sidewise motion. A straight top or seat board 5 is secured to the runner board 1 at the front end by the bolts 75 6, and to the pedestal support 4 by the bolts 7. Additional bolt holes 8 arezprovided in the seat board 5, as shown in Figures I and III so that the position of the pedestal 4 'may be changed from its intermediate posi- 90 tion either in a forward or backward direction, as desired. A seat 9 is also secured to the seat board 5. A foot rest 10 is secured to the seat board 5 by the bolts 11 and additional bolt holes 12 are provided in the seat 85 board 5 so that the foot rest may be shifted from its intermediate position 11 either forwards or backwards as desired in a manner similar to the way the pedestal 4 is'shifted In Figure IV is shown a cross section through the base board or runner board, which may be grooved at 13 if desired in order to hold the sled true to its course and prevent swerving toward the side.

It will benoted that in action the tional spring added thereto by reason of the weight of the rider being placed on the seat 9. This seat being placed to the rear of the pedestal 4,has a fulcruming or lever action tending to draw up the front end of the base board and increase the springiness of the sled as a whole. This lever action may be increased 'or decreased by shifting the pedestal out from its central position either for-v shifted from position T to position 8, and

also has an oscillatory movement in the guides about the bottom end as a fulcrum base 95 4board 1 is turned or bent up and an addiwhen the top piece changes its angle with respect to the runner through its sprin action under the application of weight an encountering varying surface conditions.

The runner board being placed under tension by the Weight of the rider, the Whole structure is very elastic, so that when the sled goes over an unevenness in the ground, such as a bump, the sled will have a tendency to bound upward and is very springy in its action, increasing the effect of the bumps and unevennesses that are gone over.

The sled may be made with one runner, as shown, or it can be provided with two lor more runners or base boards separated one from the other, as desired.

It will, of course, be understood that the base runner is made from a thin elastic Wood or material that may be tensed, as has been described hereinabove.

From the foregoing description it will be seen that I have provided a simple and eicient means for constructing a .sled very springy and elastic in its action and very simple and cheap in its construction and maintenance.

I claim:

In a sled, an unbent flexible runner, an unbent to piece having a seat portion joined at t 1e forward end of the runner and forming an angle therewith, an inflexible pedestal piece between the top piece and the runner intermediate the ends of the runner and top piece, rigidly secured to the top piece to prevent lateral movement of the pedestal, but free and unsecured as respects the runner and so positioned with rcs )ect to the seat portion that the weight of tie operator on the seat portion will bend up the front end of the runner to form the usual upturned runner ortion, and at the same timeprovide a res lent seat for the operator.
