T0 aZZ whom z'tmag concern:

Be it known that I, PETER P. Lnow, a citizen of the United States, residing at Boyne City, in the county of Charlevoix and State of Michigan, have invented new and useful Improvements in Autosleighs, of which the following is a specification.

This invention relates to sleighs of the motor driven type and an object of the invention is to provide a sleigh which maybe driven by an internal combustion engine or analogous prime mover, and one'which may be guided in anydirection desired and in which a planetary set'of gears is embodied for transmitting power to thedriving wheels.

Another object of this invention is to provide a motor sleigh as specified in which the driving wheels, which are carried by the rear runner structure, may be moved vertica'lly for regulating the action lengths of the spurs or grouters carried by their perimeters or to permit the said driving wheels'to be moved out of operative position and further to provide a novel form of mechanism for raising or lowering said driving wheels, the said mechanism being operated by single feed screw to synchronously move,=verti- 'cally, the driving wheels at the opposite sides of the sleigl Another object of this invention is to pro vide a column associated with the steering column of the motor sleigh for operating said elevation regulating feed screw.

Other objects of the invention will appear in the following detailed description and in the accompanying drawings wherein:

Fig. 1 is a side elevation of the complete motor sleigh.

Flg. 2 1s a longitudinal section through the rearor driving end of the motor sleigh. 1

Fig. 3 isa top plan of the-rear or driving end of the motor sleigh.

4 is a rear elevation of the motor sleiehshowing the parts in section.

Fig. 5 is a top plan of'the front or steering end of the motor sleigh.

Fig. 6 is afragmentarysection illustrating the steering mechanism.

Fig. 7 is asection on the line 7-'-7 of Fig. 2.

Fig. 8 is a diametrical section through one of the driving wheels.

Referring more particularly to therdra'wing the improved sleigh comprises'front and 1921. Serial No. 482,257.

rear sections which provide respectively the steering anddriving mechanism of the motor sleigh. he frontrunner section comprises front runners 1 supported and braced by the usual braces 2 and standards 3, the said runners being connected by a front axle 4: I

to which the "front runners 1 are connected by means of yol-res 5 at each end of the axle and ears Gcarried by the-standards 3. The yolres 5 are pivotally connected to-thevertically spaced sets of ears 6-so asto perm-it pivotal movement ofthe front run-ner Li -or steering the vehicle. Theaxle dis-carried by tlIG'fIZI-IEE 7 which-entry:be+yieldablysus pended by'the usualty-p'e of lea-f springs: 8

similar to the manner of suspending tlie front end ofthe chassis of am-otorwehicle. The front, runners 1 are connected, for: synchronous steering movement, by asuitable cross rod or steering rod-9 to which the arm 10 is connected "by a ball and'socket joint. The arm 10 is carried bythelowerendbf the steering post l2'u pon the upperendot' which a hand wheel13 isinounted torta eilitate manual rotation ofthe-steeringpost12 to guide the front runners 1.

The rearor propelling end: of the ;-motor sleigh comprises side trun ners-2O =andj21 which are similar in construction, eachicomprising a housing structure 22 formedof suitable sheet metal and enclosing a propelling mechanismproper.

The propelling mechanism comprises drive wheels 23 and-2carriediby.each ru-nner which have, circumferentially spaced .spurs25 on their per'imeters for biting into' the surface over which the sleigh is traveling. The driving wheels-23 and=24 are'rotatablysupported on s'uitable stub axles 26 which are. in-tuirnarotatably supported by I the auxiliary housing 27 mounted-wi-thinthe housing 22. The wheels "and reach have a driving gear 28- carried thereby wh ch meshes with an idler gear 29. The id-ler gears 29- mesh with other idler 7 gears 30 extends across the rear end of the motor sleigh structure and is connected by means of bevel gears 37 with the driving shaft 38 which is in turn driven by the prime mover or engine of the motor sleigh. The gears 29 and 30 are mounted to permit a planetary action relative to the gear 31 so as to maintain operative driving connection with the gears 28 under vertical adjustment of the driving wheels 23 and 24. The housing 22 is slotted as shown at 39 to permit the movement of the gears 29 and 30 and also'vertical adjustment of the driving wheels 23 and 24 without varying the elevation of the run ners 40. The auxiliary housing 27 is mounted within the housing 22 for movement verti' cally therein and its end portions engage the ends of the housing 22 to guide its vertical movement. An arm 41 is connected to the top or apex of each auxiliary housing 27 and the arms on each of the housings are connected in any suitable manner. Each pressure post or arm 41 is connected, by a link 43, with a pivotally mounted lever 44. The lever 44 is pivotally supported upon a suitable bracket post 45 carried by the housing 22 and its short end is engaged by a roller 46 carried by the frame 47 Rollers 48 and 49 are also carried by the frame 4'? and they engage against the guide rail 50. The frame 47 has a nut 52 thereon which is mounted upon a feed screw 53, supported by suitable bearings 54 on the frame 55 and the feed screws 53 at the opposite sides of the motor sleigh frame are connected by a cross shaft 56 and suitable'bevel gears 5'7- The cross shaft 56 is connected by bevel gears-58 to an operating rod 59 which extends forwardly and is rotatably supported at its forward end by a suitable depending bracket 60. A bevel pinion 61 is mounted on the forward end of the rod 59 and meshes with a bevel gear 62 carried by the lower end of the column sleeve 63. The sleeve 63 is rotatably mounted about the steering post 12 and has a hand wheel 64 thereon for permitting its" manual rotation thereby allowing adjustment of the pressure applying members comprising the frames 47 and rollers 48 from the operators' seat of the motor sleigh. 'As the pressure applying members are moved rearwardly, through.

rotation of the rod 59, the levers 44 are rocked upon their pivots forcing their rear ends downwardly and applying downward .pressure to the auxiliary housing 27 moving the driving wheels 23 and 24 downwardly and when the pressure applying members are moved forwardly the pressure on the levers 44 is reduced and consequently the weight of the motor sleigh will cause the driving wheels 23 and 24to move upwardly as far as permitted by the pressure levers '44.

Suitable guards 66 areprovided for preventing the throwing of snow by the drive wheels 23 and 24 during their operation. As clearly shown in Fig. 2 of the drawing the rear runner structures 40 are formed of front sections 67 and rear sections 68 which curve and merge into the housing 22 being braced by suitable braces 69 to provide suffi cient rigidity to the runners and during operation of the motor sleigh the front runners 1 and front portions 67 of the rear runners 40 will pack the snow sufficiently to provide a firm surface into which the spurs 28 will burrow for propelling the motor sleigh.

The rear runners are connected by a detachable cross brace 70 and the connecting bar 42 is connected to said cross brace 70 by means of suitable pins 71 riding through the cross brace and being braced in'turn by diagonal braces 72.

Summing up, the operation of the improved motor sleigh is as follows:

The motor sleigh is steered by means of the steering wheel 13 through the medium of the cross rod 9 and steering post 12 to permit steering of the travel of the sleigh and it is propelled from an internal combustion engine or analogous prime mover through the medium of the rear drive shaft 36 and the sets of gearing carried by each of the rear runner structures 40. Varying conditions will require variation of the elevations of the drive wheels 23 and 24 and by rotating the hand wheel 64 the elevations of the drive wheels may be regulated as desired and made necessary by existing conditions. In traveling down inclines the drive wheels 23 and 24 may be moved out of operative position, that is, with the lowermost points of the spurs 25 above the under surfaces of the runners of the sleigh so as to permit the sleigh to coast down such inclines. When coasting the braking operation of the sleigh may be controlled by varying the elevation of the drive wheels, the weight of the sleigh causing it to stop.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts'associated in different relations and, therefore, I do not desire to be limited in any manner exceptas set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. In a power driven sleigh, rear runner structures, housings carried by each of said runner structures and mounted for vertical movement, guide rails carried by the sleigh, feed screws, plates adjustably supported by said feed screws, rollers carried by said plates and engaging said guide rails. and means operated by movement of said plate along said feed screw for raising or lowering said housing.

2. In a power driven sleigh, rear runner structures, housings carried by each of said runner structures and mounted for vertical housings, and a roller carried by said plate and engaging said lever for forcing the lever and housing downwardly upon movement of the plate along the feed screw in one direction and for forcing the housing upwardly upon movement of the plate along the feed screw in the opposite direction.

3. In a power driven sleigh, rear runner structures, housings carried by each of said runner structures and mounted for vertical movement, guide rails carried by the sleigl'i, feed screws, plates adjustably supported by said Vfeed screws, rollers carried by said plates and engaging said guide rails, a pivotally supported lever normally resting on an incline, means connecting said lever and housings, a roller carried by said plate and engaging said lever for forcing the lever and housing downwardly upon movement of the plate along the feed screw in one direction and for forcing the housing upn-ardly upon movement of the plate along the feed screw in the opposite direction, a plurality of driving wheels carried by said .movable housing an operating shaft, and

a train of gears connecting said operating shaft and said driving wheels.

In testimony whereof I afiiX my signature.

PETER LEOW.
