MEGHANIGALLY-PR-OPELLED SLED.

Application filed September 2, 1909.

ically-Pro1')elled Sled; and I do hereby dc clare the following to be a full. clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ref-- erenee being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specitication.

My invention relates to hand operated sleds; and has for its object the provision, in association with a. sled, of simple, improved and efiicient means for rapidly propelling the sled over snow or ice. and which atthe same time serves as an exercising means for the operator.

The operation, construction and arrangement of the parts of the invention are fully described in the following specification, and a preferred embodiment thereof illustrated in the accompanying drawings, in which,-

Figure 1 is a plan of a sled embodying my invention. with a portion of the seat broken away. Figs. 2 and {l are side and front end views, respectively, of the same. Fig.4 a front view of a portion of one of the push rod guide-brackets, with such rods in section. Figs. 5 and ti are sections on the lines w a: and y 7 respectively, in Fig. at.

Referring to the dra 'ing it, 1 designate the runners, 2 the seat, and 3 the seat-supporting le 's of a sled of any suitable construction. A. steering-runner 4: is carried at the lower end of a. fork-head 5, which is mounted for free vertical and turning move ments in the center of a cross-piece (3, con necting the forward ends of the runners 1, and which is fixed at its upper end to a cross or foot-bar 7. The runner 4 is maintained in yielding contact with the surface over which it. is passing by means of a coiled expansion spring 8, the upper and lower ends of which bear against. the cross-piece 6 and runner 4, respectively.

Disposed in advance of the seat. 2 is the OPEIELl'lIlgdtVQI, which is shown in the present' instance as comprising the two lever members 9, 9, which are connected at their upper ends by a handle 10 and are fixed near their lower ends to a shaft 11, the ends of Specification of Letters Patent.

Patented Sept. 6, 1910. Serial No. 515,745. x

which are suitably journaled in framepieces 12, 12, extending from the forward ends of the runners l to the forward legs 3 of the sled.

Pivotally attached at their forward ends to each lever 9 is a pair of push or kickerrods 13, 13, which are attached to their respective levers at equal distances above and below the shaft 11, as shown. These rods project through guide-blocks or boxes 14,

.14, which are suitably mounted for vertical movements in. vertically-disposed slots 15, 15 provided in brackets 1'6, which are pendently secured to the bottom of the seat 2, one of such bracltets being provided for each set of push-rods, as shown. The rods 13 are each pointed at their rear ends and declined rearwardly or angled as shown to adapt them when the levers 9 are oscillated to dig into the snow or ice over which the sled is passing and thus propel the sled. The pointed or rear ends of the rods are held in yielding contact with the surface of the snow or ice by means of coiled expansion-springs 17, one of which is disposed bet-ween each guide-block 14 and the upper end of the associated slot 15.

It is apparent. that to propel the sled it IS only necessary for theoperator to seat,

himself on the sled, place his feet on the ends of the foot-bar 7 for the steering of the sled through the medium of the steeringruuner 4t, and then work the levers 9, 9 back and forth. The oscillatory movements of the levers 9 causes the upper and lower sets of push-rods 13 to alternately kick back with their pointed ends in, engagement with the surface over which the sled is running and elfecta propelling of the sled.

I wisa it understood that my invention is not limited to any specific construction or arrangement of the parts, except in so far as such limitations are specified in the claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, i s,

1. The combination with a sled, of a lever fulcrumed thereto, push-rods pivotally projecting rearwardly from said lever from above and below its fulcrum and having their rear ends pointed, a pendentbracket, carried by the sled seat andhaving vertical slots therein, .anduide-blocks mounted 1n said slots for yielding vertical movements therein 2 having 01.1 's themhhreugh flare-ugh 10h sand rofls 1 to be in yie. 'cafniact with the Bur face ovey Whiah he sled is passinm In testimcny Whereaf I have hereunto signed my name in the'presence of two subscribing witmssea HARRY DAY.
