S. TIRRITH HAND PROPELLED sLED Filed Nov 1.. 1922 Patented Oct. 30, 1923.

PATENT ofi-Fica sm TIRRITH, or Torrano, oHIo.

HAND-IROPELLED SLED.

Application filed November' To all whom it `may concern:

have invented certain new and'useful Im-v provements in a Hand-Propelled Sled; I do hereby declare the following to be a full, clear, and `exact description of the invention, such as will enable others yskilled in the art to which it appertains to make and use the same.

The object ofthe invention is to provide a simple and eiiicient` sled of the hand propelled type adapted for use either as an 'amusement device tobe made yof a comparatively small size for juvenile operation or for utility purposes in localities where snow and ice are prevalent during a considerable portion Vo-f the year; and with these objects Vin view thev invention `consists in a construction and arrangement of parts of which a preferred embodiment is shown in the accompanying drawing, wherein:

kFigure 1 is a side view and Figure'2 is a plan view ofa sled embodyino` the invention,

igure 3 is a longitudinal sectional view of the same, i

Figure .4 is a transverse section on th 30 plane indicatedby the line 4 4 of Figure 3. The structure embodies essentially the runners which are extended upward at their rear ends to form standards 11 and are connected at -their lupturned forward ends by an arch 12 to serve as a fender or bumper, a seat frame -having side ymembers 13 arranged for support by `said runners and provided latits rearend with a seat 14 which may have a suitable back 15, and propelling ed as through the agency of handlevers 16 which are mounted for Swingin movement upon a transverse fulcrum bar 1 supported by the runners and suitably braced from the seat frame. Y y

The runners are preferably provided with offsets or lateral extensions 18 forming foot rests for the occupant of the seat and eX- tending from the fulcrum bar longitudinab,

ly of the structure to the seat and connected with the latter by hanger rods 19 are guide rods 2O which are arranged in pairs and are parallel to form guides for the push rods 21 which are pivoted at 22 respectively to mechanism whichV may be `manually operat- 3 Y oscillatory movement of the hand levers by the hand levers and arek provided with 1, 1922. seriai Nasasss.'

terminal spurs or points 23 for yengagement `with the `surface traversed by the runners.

The retraction of the push rods is effected Y by `means of contractile springs 24 extendi ing thereto from the fulcrum bar or other convenient point of attachment and the guides are preferably provided with supporting rollers 25 which serve to `carry the push rods during their return movement unf `der the action of the springs V24 to prevent the dragging of the terminal spurs 23 on the surface supporting the vehicle. Also each push rod is preferably provided ywith lateral guide rollers 26 serving to minimize 'friction Vin the reciprocatoryk movement of said yrods by Contact with the members of the guides. Each of the rollers 25 is carried by a suitable support 27 having a vertically disposed portion 28 journaled in the side .member 13 and in a bracket 29 suspended `from the side member. `The supports 27 ,have inwardly vdirected portions 30 at their upper ends and springs 31 are connected `with the portions 30 and with the seat 14 and serve to return the support and their rollers to their normal position when they are moved `from such position.

yOn forward movement of the sled under power applied .in the proper manner to one ofthe handles 16 theactive push rod 21 will be engaged by its respective roller 25 yandthe roller and its support'will `be swung on their pivot and lwill permit the lpassage of the `push rod. As soon as the push rod vpasses the roller, the roller will be returned to its normal positionr by the spring 31. Forward movement of the push rod will then bring it into contact with the roller and the push rod will :be elevated.

rIt will be obvious that by an yalternate the occupant of the seat 14 a continuous forward motion may be imparted to the sled or the other according to the direction in which it is desired toprogress.

The structure disclosed may be used either as an amusement device for children or in the proper sizes may be employed for general transportation purposes in lieu of other types of vehicles, either'for business or pleasure and under such conditions as to aiord opportunities for pleasurable exercise. ,v i a -r Having thus described the invention, what I claim as new is:-
