SLED-PEOPELLER MEANS.

Appficatioii filed April 5,

The present invention relates to attachments for coaster sleds, and has reference more particularly to a manually operated propelling means therefor.

One of the important objects of the pres ent invention is to provide a manually operable propelling meansthat can be readily and easily attached to conventional sled of the coaster type without necessitating any material alterations of the parts of the sled with which said propelling means is associated, the device being at all times positive and efficient in carrying out'the purposes for which it is designed.

Still a further object is to provide a sled propeller means of the above mentioned character, which is simple. in construction, inexpensive, strong and durable and fur ther well adapted to the purpose for which it is designed.

In the accompanying drawing wherein like reference characters indicate correspondin parts throughout the same:

Figure 1 is a fragmentary side elevation of a conventional coaster sled showing our improved propelling n'ieans mounted there Figure 2 is a top plan view thereof, and

Figure 3 is a vertical sectional view taken approximately on the line of Figure 1 looking in the direction of the arrows.

In, the drawing wherein for the purpose of illustration is shown the preferred embodiment of our invention, the numeral 1 designates generally a coaster sled of the conventional construction, the platform or body supporting member thereof being desig nated by the numeral 2.

Our attachment includes a bracket 3 that is secured on the forward end of the platform 2 in a rigid manner, and formed in the platform directly rearwardly of the centrally loca ed bracket 3 is the longitudinally extending slot 4 as more clearly shown. in Figure 2, the purpose of which will be presently described.

Alever 5 is formed at its lower end with the offset portion 6 and cooperating with this offset portion is the angular piece 7 whereby a yoke is formed and this yoke is pivot-ally 1928. Serial No. 267,769.

connected to the bracket 3 so that said lever 5 will be capable of vertical swinging movement. A handle bar 8 extends across the upper end of the lever for actuating the same.

Forming a salient part of the present in vention is the elongated curved propeller bar 9 that is pivotally secured at its upper end to the intern'iediate portion of the lever. 5 at 10. This propeller bar is operable within the longitudinal slot 4, the lower end portion of the bar projecting through said slot clearly shown in Figure 1.

The lower end of the propeller bar 9 terminates in the fork 11, the free ends of the flu-cations thereof being sharpened to provide ice or snow penetrating prongs 12.

From the foregoing it will be obvious that the sled 1 can be propelled very rapidly over the ice and snow by actuating the lever 5 so that the pointed prongs 12 will penetrate the ice or snow when the lever is swung 'rearwardly and the propeller bar 9 moved downwardly. By moving the lever 5 forwardly into the position shown in the dotted lines in Figure 1, the propeller bar 9 will be raised to inoperative position, thereby permitting the occupant of the sled to coast.

The simplicity of our propelling means enables the same to be reaeily and easily ttached to any conventii'inal coaster sled without necessitating any material alterations of the sled and furthermore our improved propelling means will at all times be positive and ellicient in its operation.

While we have shown the preferred embodiment of our invention, it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what we claim is In combination with a conventional coast er sled wherein the platform or body thereof is formed with a longitudinal extending slot in the forward central portion, a bracket rigidly secured on theforward end portion of the platform in front of the slot, a vertically swinging lever provided with a yoke at its lower end for pivotal connection to the bracket, a. handle bar on the upper end of the lever, a propeller bar extending 5 thro-ugh'the slot, the upper end of the propeller bar being pivotally secured to the intermed'iate portion of the lever a fork iorined on the lower end of the propeller bar, the free ends of the fureations of said fork being pointed to provide ice penetrating prongs.

In testimony whereof we :iflix our signatures.
