at its bottom end with an inwardly extended cutout into which the top edge of the central rib I8 extends.

A bolt 21 is extended through the overlapping portions i8 and the shaft 25 for pivotally mounting the front runner upon the bottom of the shaft 26 permitting a slight pivotal motion to permit the front runner to more easily ride over obstacles in its path The top end of the shaft 25 extends through a bearing 28 and is attached thereto by means of a pin 2Q. The free end of the shaft 26 extends through the platform and engages into a thrust bearing 23' mounted on the top face of the platform the tcp thereof, and extending rearwards along the top face of the runner portions I5. This shield 3U acts as a guard to prevent snow and ice from being thrown upwards into the riders face.

The front runner l1 isalso provided with a protective shield 3|) mounted on pivot -rearwarda as indicated by the dot and .i

dash lines I9' shown in Fig. 2, to assume a horizontaly position and rest on the top face of the platform A To accomplish this the disc 3| is provided at diametrically opposite sides with trunnion elements 33 which pass through the .y

lower corner ofthe semi-circular casing lil and which are provided with nuts 34 for securely holding the casing Il! in position thereon. The trunnions 33 permit rearward pivoting of the casing IIJ to reduce the over all size of the device and permit a number of superimposed scooters to be conveniently carried in a truck body to be transported from place to place.

' yFor convenience of the operator the casing ||l isprovided on vdiametrically opposite sides with L handles 35 which may be gripped for turning the casing to steer the device. The casing I3 is also .provided with a plurality of guns 33. If the device is -to be Aused as atoy the guns 36 should also be toys. However, if the device is constructedqfor use in warfare the guns 36 might be of the machinegun or other semi-automatic type,

capable of shooting a low calibre bullet.

yA means is provided for latching the casing |0-in a verticalposition on the platform to prevent relative pivoting. This means comprises a bolt, member 31 pivotally mounted upon a bracket 38 attached to the inside face of the 'casing |93.. A keeperA 39 ismounted on the top face of the disc 3| and is adapted to be engaged by the bolt 31 for locking the casingagainst pivoting; `A means is provided for urging the bolt 31 into a position 4in which it engages the keeper 39. .This means comprises a pin 40 attached to the free end-of the bolt 31 and passing through i .anopening 42 formed in the front of the casing |0. A spring 4| is coaxially mounted upon the mounted-.upon a bracket 44 attached to the in- :i

. sideface of the casing ||l above the bolt31.

The bell crank 43 has one arm bearing against the free end of the bolt 31 on the side opposed to the side engaged by the spring 42. The other arm of the bell crank 43 is free to be engaged by ones foot for pivoting the bell crank and in turn pivot the bolt 31.

A resilient means is provided between the disc 3| and the front end of the front runner I1 for urging the front runner int-o a normal horizontal position relative to the disc 3|. This means comprises a spring 45 having a coiled central portion with one end secured to the bottom face of the disc 3| by means of a bolt 46. The other end of the spring a5 is looped and passed through an opening :l1 formed in the central rib |8 of thev front runner |1. The spring 45 normally acts to restrain the front runner l1 from pivoting about the bolt 21.

A drawer G8 is supported at an intermediate area on the bottom face of the platform |I. This drawer 48 is supported by means of a wide bracket t9 and is adapted to be used for `carrying ammunition or other similar articles.

The rear runner I6 is also providedwith a braking device for permitting the forward motion of the device to be conveniently retarded when desired. This means comprises a brake platform 55 having its front edge resting upon thetop face of the rear portion of theplatform ll. Pivotally mounted to the bottom face of the brake platform 50 is an inverted U-shaped member 5|. This inverted U-shaped member 5| has its side arms directed downwards and provided at their free ends with pointed portions 52which are adapted to engage the ground and dig into the same to retard the forward motion of the device when the operator steps upon the brake platform 5b. A means is provided for holding the brake device in an inoperative position. This means comprises a bracket 53 having one of its ends pivotally attached to the downwardly extending arms of the inverted U-shaped member 5| and its other end pivotally attached into the pin 54which attaches the rear runner I6 to the rod 24. A spring 55 operates between the bracket 53 and the bottom face ofthe platform H for raising the bracket 53 to in turn raise the inverted U-shaped member 5|.

A bell 56 is mounted on the side of the platform-|| and has an operative member 51 extending rearwards therefrom to be urged upwards to cause the bell 56 to ring. A lever 58 is pivotally mounted intermediate of its ends upon a pin 59 mounted on the side of the platform 51. The rear end of the lever 58 is securely attached to the brake platform 50. The front endof the lever 58 is arranged immediately adjacent the operating lever of the bell 56. Thus when the operator steps upon the Abrake platform to retard forward motion of the vehicle the lever 58 will pivot causing the bell 56 toring and indicate to the operators of following scooters that the front scooter is being slowed down and that they should take similar action to avoid collision. y Y i The operation of the device is as follows:

Assuming that the device is constructed for use in warfare, the soldier stands upon the platform grips the handles 35 and propels himself forward across the snow by using one foot to; push on the ground while the other foot rests upon the platform.A To turn the device the casing I0 is turned and this movement is transmitted tothe front runner |1 .through the connection of the front runner with the casing l0 through the obstacles with greater ease, a dis-c supporting said semi-circular casing and being turnably mounted on the front of said platform coaxially of said turnably. mounted runner, a trunnion mounted on said disc and connected with the rear side portions of said semi-circular casing for pivotally supporting said casing so that it may pivot rearwards, means for latching said casing in its vertical position on said disc, and resilient means between said disc and said front runner for urging said front runner in a normal horizontal position relative to said disc, said means for latching said casing comprising a bolt pivotally mounted upon said casing and engaging a complementary keeper mounted upon said disc, resilient means urging said bolt to continually engage said keeper, and means for releasing said bolt when desired.
