following is a specifica- Fig. 7 is a detail sectional view approximately on the line 7--7 of Fig. 2, illustrating the manner in which the stud' of the lever engages one-of the'apertures in the plate arranged to one of the sides of the device, and I Fig. 8 is an enlarged sectional view approximately on the line 88 of Fig. 3.

In constructing my improved motor propelled toy, it is to be understood that any desired material may be employed and that such shapes and proportions may be used as may be desired as the improvement is not necessarily restricted to that of a toy, but may be constructed of such a size as to permit of the same carrying passengers, in

which event the body of the machine will be provided with suitable seats.

In-the embodiment of the improvement as disclosed by the drawings, the body 1 is of a substantially rectangular construction and includes a flat top 2. The body, at-the forward end thereof has secured thereto the flanges of depending bracket members 3, one of said brackets being arranged adjacent to each of the sides of the body and each ofsaid brackets has its depending plate provided with an elongated opening 4. These opening-saline and. have passed therethrough the front axle 5, the ends of said axle having journaled thereon suitable wheels 6. The axle 5 is preferably centrally enlarged and is arranged upon a suitable support 7 that is secured to a plate 8, the said plate being con nected to the front of the body and preferably secured to the outer edges of the brackets'3. Secured to the referred to central portion of the axle 5 and journaled in bearings in the support 7, and having its lower end provided with a lug or other retaining member 9 is the king pin for the axle. This pin 10 projects through a suitable bearing opening in the top 2 of the. body and has sea e5 cured to its upper end a pinion 11.

- Secured to the front plate 8 and pro ecting outwardly therefrom is a pair of sleeve members 12, and passing through each of these sleeves is a rod member 13. The outer ends of these rods 13 haveconnected thereto a curved bar 14: which provides the bumper for the device. The opposite orinner ends of the rods 13 are connected by a cross plate 15 and the said plate 15 is normally moved in the direction of the front plate 8 of the body through the medium of helical springs 16 which are connected to the said cross plate and to the inner face of the .front plate 8, whereby the bumper will be normally retained a suitable distance in advance of the front of the body. The rods 13 are provided with stop members 17 which are adapted to contact with the inner face of the front plate 8 to limit the movement of the bars in an outward direction with rela tion to the frame or body. The connecting plate 15 has secured thereto a rearwardly extending cam member 18 and the purpose of this arrangement will be hereinafter fully set forth. 7

The rear axle 19 is journaled in suitable bearings 20 and has upon its ends the propelling wheels 21. The axle 19, inward of one of the wheels 21 is provided with a brake wheel or rim 22 which is adapted to be contacted by a brake shoe 23, the said shoe being preferably constructed of flexible material, such as rubber and the same having an arcuate face to snugly engage with the brake wheel or rim 22. The brake shoe is provided with a'brake rod 24 which is mounted for longitudinal movement in suitable bearings 25, the free end of the rod having pivotally connected therewith a link 26, and the said link has its free end pivotally secured to an offset member or finger 27 formed with the brake lever 28. The lever is pivotally secured to a depending plate or bracket upon one of the sides of the body, the said plate projecting above the top 2 of the body and having its upper end arcuate or struck concentrically from the pivot connecting the lever with the plate, and the said plate adjacent the said upper curved edge is provided with a plurality of spaced apertures 29 while the brake lever is provided with a pin 30 which is adapted to be brought to engage with any one of the apertures whereby the desired amount of pressure between the brake shoe and the brake band may be maintained and the speed to which the machine travels regulated. lit is, of course, to be understood that when the brake shoe is brought to engage with the brake band at a desired frictional contact the propulsion of the machine will be halted. The means for propelling the machine will hereinafter be more fully set forth.

Arranged centrally and secured to the underface of the body, at the rear portion thereof, is a substantially rectangular body like casing 31, the rear axle 19 passing through suitable openings, but may also provide bearings for the said axle, and the portion of the axle-within the said casing has i loosely arranged theaecia comparatively small gear wheels 32 and 33. Each of the gears 32 and 33 have their inner or confronting sides flanged and the said flanges provided with inwardly extending lugs 34. If desired, the adjacent or confronting faces of the said gear wheels 32 and 33 may be cam-shaped, whereby to engage with the opposite camshaped faces of a clutch sleeve 35 which sleeve, however, in the construction illus trated by the drawings, has its opposite provided with pins or lugs 36, the clutch sleeve being provided with a feather which is received in a groove in the axle and it will be apparent that when the same is brought to have its clutch face or lug engage with the clutch face or lug of either of the gears 32 or 33, one of the said gears will be revolved to rotate the axle 19 in one of two directions, as will hereinafter be more fully apparent. The clutch sleeve 35 is centrally provided with an annular groove 37 which is engaged by a finger 38 provided upon a member 39 that is secured to a transversely disposed rod 40 the said rod having one of its ends formed with an eye which is engaged by a helical spring 41 that is secured to the body 2 will be normally propelled in a forward direction, as will hereinafter be fully understood. The opposite end of the rod 40 is connected with an arm 42, the said arm be ing approximately centrally pivotally connected, as at 43, to a depending member or lug 44 secured to the body of the machine, and the free end of the arm is provided with a beveled or cam surface 45 that is slightly out of contact with the, cam member 18, and by this arrangement it will be apparent should the bufler member 15 contact with an obstruction, the rods 13 will be forced rearwardly against the pressure of the springs 16 so that the cam member 18 upon the connecting member 15 of the said rod will engage with the cam end 45 of the arm 42 to swing the arm upon its pivot 43 and consequently move the rod 40 longitudinally through its bearings to cause the finger 38 upon the member 39, secured to the said rod 40, to slide the clutch 35, thus bringing one of its cam faces or lugs 36 to engage with the cam face or lug 34 of the gear 33, causing the rotation of the said gear and the re Verse movement of the propelling wheels as shaft 17 has loosely arranged thereon a gear s ur wheel 48 and has secured thereto a ratchet wheel 19 that is normally engaged by a dog 50 that is pivotally secured to the spur gear 18. Also journaled in suitable bearing openingsin the sides of the casing 31 is a second shaft 51 that has keyed or .otherwise secured thereto a pinion 52 that meshes with a gear 18. Secured to the said shaft 51 is a gear wheel 53 that meshes with a gear upon the rear axle 19. Also secured upon the shaft 51 is a toothed wheel 54 that meshes with a toothed idler wheel 55 and the wheel 55 meshes with a gear 33 upon the rear axle 19. By this arrangement it will be noted that the gear 33 normally runs loose upon the axle 19 while the gear 32 is normally engaged by 'the clutch member 19 to propel the machine in a forward direction and it will also be apparent that when the bumper contacts with the obstruction the same moves the rods 13 and the connecting plate 15 for the said rods in a rearward direction, the cam member 18 contacting with the cam surface 45 upon the arm 12 will, as hereinafter described, swing the said arm upon its pivot to draw the clutch member into engagement with the gear 33, and through the medium of the toothed wheel 55 meshing with the said gear 33 the machine will be propelled in a rearward or reverse direction. It will be noted that the movement of the wheel in a rearward or reverse direction will be of a comparatively short duration, and as itis obvious that should the machine be again propelled in a forward direction, the bumper willagain be brought into contact with the obstruction, I provide means for automatically turning the front axles to steer the machine away from the obstruction.

Secured to one end of the shaft 51 is a beveled toothed wheel 56 which engages with a similar toothed wheel 57, that is secured to a vertically disposed shaft 58, the said shaft being mounted in suitable bearings and projecting through an opening in the top 2 and having its upper end provided with a toothed wheel 59.

Mounted for rotation upon a vertically disposed stud shaft 60 is a flat wheel 61, the said wheel having a plurality of spaced notches, certain of which being arranged in stepped relation with each other, as indicated by the numerals 62 and 63, whereby the flat wheel 61 is provided with a plurality of spaced cam surfaces. Secured tothe underface of the cam wheel 61 and also journaled upon the stub shaft 60 is a toothed wheel 61 that meshes with a toothed wheel 65 which-in turn meshes with the toothed wheel 59, and by this arrangement it will be noted thatwhen the motor shaft 47 is revolved to turn the shaft 51, the cam wheel between the outer bearing 68 and the collar.

69 to project the rollers 65 in the direction of the wheel 61, and against the periphery of the said wheel and be engaged by the cam surfaces on the said wheel. The rod 67 has its forward or outer end provided with a rack bar, 71, the teeth of which co-engage with those of the pinion 11 upon the king pin or shaft 10 of the forward axle 5, and by this arrangement it will be noted that the forward or front axle 5 will be turned at spaced but determined intervals so that the machine will be caused to travel an irregular course. The roller when contacting with the cam surface 63 of the wheel 61 will, for instance, cause the machine to be propelled, say, in a right hand direction; when the wheel is brought to contact with the cam surface 62, the axle 5 will be turned directly at a right angle tothe body of the device, and so the machine will be propelled in a straight direction, while when the roller is brought to engage with the peripheral surface 72, the axle will be turned to cause the machine to be propelled in, say, a left hand direction, and thus it will'be noted that in accordance with the notches or steps in the periphery of the wheel 61, the machine will at all times be propelled in various directions and, as previously stated, when brought to contact with an obstruction will reverse itself and be again propelled in a forward direction away from the obstruction.

"As the device is primarily adapted to be constructed in the form and shape of an ordinary automobile, I provide novel means for winding the spring motor 46. Upon the front plate 8 of the body centrally between the spaced sleeves 12 I provide a sleeve 73 which has passed therethrough ashaft 74,

the outer end of the said shaft being approximately square in cross section and receiving the squared bore of'the tubular mem- 7 her 75 formed with or secured to a crank 76. The inner end of the shaft 71 has arranged thereon a pinion 77 which meshes with a similar pinion 78 that is secured on a shaft 79 carried by the plate 8. The said shaft 79 projects inward of the body of the machine and having a. knuckle connection with a rod'80,.the opposite or free end of the said rod 80 having a knuckle or universal joint connection with a shaft 81 that is journaled in a suitable bearing sleeve 82 secured to the body of the machine and that has its end provided with a beveled toothed wheel 83 that meshes with a similar toothed wheel 84; that is secured upon one of the ends of the motor shaft47 that projects through its bearing opening in one of the sides of the casing 31. By actuating the crank 76 it will be noted that the motor will be wound from the front of the device, and from the foregoing description when taken in connection with the drawings the construction and operation of the improvement will, it is thought, be apparent without further detailed description.
