BABY-CARRIAGE.

Application filed July 15, 1919, Serial No. 310,953. Renewed April To all whom t may concern:

Be it known that I, JOSEPH WEASLER, a. citizen of the United States, residing'at Cascade, in the county of SheboyganyState of lVisconsin7 have invented certain newT and useful VImprovements jin Baby-Carriages; and I do hereby declare the following to be a full, clear, and exact description of the invention; such as'will enable others skilled in the art to Yu rhich"i'tjappertai-ns to make 'and use the same. A

This invention is an improvement 1n motor vehicles andhas particular reference to a reciprocating mechanism Vfor baby carriages. Y An object of the invention is to provide improvedl means for imparting areciprocatory movement to the'vehicle, saidmeans having portions thereof adjustable in order to regulate ythe length of such'movement.

Another Objectis to render inactive the means for reciprocating the'vehicle when it is 'desired to 'propel the latter from one place'to another.

A further object is the provision of a mechanism lfor decreasing the speed ofthe vehicle as the same rapproachesthe ends of its reciprocating 4movements 'in order that the direction lof travel-be' reversed without unduejerking.

A still further object is the provision of a mechanism ofthe 'character specified which is simple in construction, easyv to manufac ture and elfective" in carrying out the purpose for which 'it is designed:

` 'The inventive idea involved is capable of receiving' a variety of mechanicalexpressions, one of which, for thepurpose of illus trating the invention,v is shownV in the ac- Cempenyin'gArawngwhereinnv"Figure-1 is "a''side lelevation of a baby carriage constructed in i accordanceI with lthe invention.

Fig. 8 is a detailed perspective view of the means for regulating the length of movement of the reciprocatory element.

In the drawings, the numeral 10 indicates the body of a baby carriage which maybe of any desired construction and which is provided with the front and rear axles 11 and .12,V respectively, upon which aremount'- ed the wheels 13 in the usual manner.

A rectangular casing 14- is preferably' supported in a desired manner beneath the body 10 and is employedfor inclosing the mechanism for reciprocating the carriage or ve# hicle. A frame is mounted within the casing 14.` and preferably includes the longitudinal bars or members 15 and the end bars or members 16. Preferably mountedv in suit able bearings 17 carried by the bars 15 adjacent 'the rear ends thereof is a trans verse driveshaft 18 upon which is mounted a motor casing 19 having a vspring20 `therein one end ofy which is securedfto the shaft so that when the'springl is unwinding thesame will operatetorotate Ythe shaft 18 inthe "de sired direction.` One end of theshaft 18 projects through the casing '14 and is provided upon the exterior endV thereof with a crank handle 21 used to"wind"th`e spring A20 after the same has been unwound. Since the construction of this spring motor may be of anydesired'type a further detailed de scription thereofis deemedV unnecessary. A trai-nn of gearing is employed for ltransmitL ting the rotation of the `shaft 18 to thefront axle 11 of the vehicle and preferably cornprises a large 'gear 22 lmounteduptmV the shaft 18 betweeny the bars `15 "and lmeshing shaft 24. supported upon 'the bars 15 in a `parallel relation tothe" shaft 18.' This ysha`ft`24 Valso carries a large 4gear 25 whichfin l turn, meshes with small "gear 26 supported upon a third shaft 27 mounted in bearings upon the bars 15.I The 'ends `of the'iishaft 27 project beyond the sides of the bars 15 and have secured theretothe drive disks 28 and 29, the former having' connected thereto a pitman rod 30 which is also pivotally secured to an 'oscillatory lever 31 the other endv ofwhich is 'connected by a link 3 2, to one'end of a reciprocatory raclc bar 33 havin the teeth 3411115011 itsunder sur# face2 sai bar being slidable ina guide carriedby4 the "adjacent'har l5; Preferably carried by the front axle 11 is a small gear,

36 which meshes with the teeth 34 so that when the rack bar 33 is reciprocated an oscillatory movement will be imparted to the` gear 36 and consequently the axle 11 to move the vehicle back and forth. The

pivot 37 ofthe lever 31 is vertically ad-V hicle back and forth, it being understood that whenthe pitman is in substantial horizontal alinement with the rack bar the latter will have its shorter length of movement. To adjust the bell crank 39, the other end thereof is connected to one end of a rodl 40 which extends rearwardly of the casing and is connected at its rear end to-an adjusting lever 41 pivoted to therear transverse bar 16 and operable in a slot 42 in the rear end of the casing 14 andextending within reach of the operator so that the lever maybe readily adjusted. A notched quadrant 42 has its ends secured to the rear of the casing 14 and is provided thereon with numbers or other suitable indicia to indicate the desiredlength of movement of the vehicle andthe lever 41 is provided with a tooth 43 engageable with the notches of the quadrant 42 in order to retain the lever 41 in its adjusted position, it being understood that the saidA lever is of sufficient resiliency to permit of the tooth 43 being disengaged from a notch and moved over the quadrant to any desired position in order that the length `of the movement of the vehicle may be changed.

It becomes desirable, at times, torpropel the carriage or vehicle from one place to another and in order to accomplish this purpose it is necessary that the rack bar 33Ybe disengaged from the gear 36. To this end, a'liftmg lever 44 is provided upon one end with a pin 45 engageable in a slot 46 formed in the upper edge ofthe rack bar 33 so as topermit ofv a reciprocatory movement of saidbar. The lever 44 is pivoted intermediate its ends at 47 and is connected at its other end to abell-crank 48 which is in` turn connected to a rod 49 extending rearwardly of the casing `14 and connected to an adjusting lever 50 mounted exteriorly of the'cas- Y ing and within reach of the operator so that by adjusting the leverl 50 the lever 44 may be caused toralse the forward end of the rack bar and disen age the teeth 34 thereof from the gear 36 ich will render the rackbar inoperative and permit ofthe vehicle being' vconstantly propelled in one direction.

` It 4will be 'apparent from the description ofthe operation of the rack bar 33 that if the speed of the reciprocating movement thereof remained constant there would be a decided jerking of the vehicle at the ends of its movements which would negative the purpose of moving the vehicle back and forth and in order to overcome thisjeriring it is purposed to gradually decrease the speed of movement oftherack bar as Athe same approaches the ends rof its strokes. In order that this purpose may be accomplished., a cushioningy means is provided which preferably comprises an air cylinder 51 supported within the casing 14 and having air outlets 52a-djacent each Vend thereof which are controlled by means of'valves 53V for the purpose of opening and closing said outlets. A piston rod 54 is slidably mounted in the cylinder 51 and has mounted thereon interiorly of the cylinder a piston 55 which will compress the air in the cylinder on either side ofthe piston asthe same is reciprocated and owingto the small size of the outlets 52 it will be apparent thatthe column of air on either side of the piston will gradually retard the movement. thereofas the same approaches either end of the cylinder andwhen the valve 53 is in opened position. The outer end of the piston rod 54 is connected to a pitman 56 which is in turn connected to the diskl 29 so that as the latter rotates a i reciprocating movement will be imparted to the piston rod. @wing -to the variationin speed of the reciprocation of the piston 55 it will be apparent thatzthe speed of rotation of the disk 29 and consequently the disk 28 and other parts connected thereto will also be'varied accordingly. Means are'provided for adjusting the valves 53 to open and close the outlets 52 and said means comprises a rod 57 connected, at one end, to the valve53 and at its other end to an adjusting lever 58 pivotally mounted upon the casing 14. lBy closing the outlets 52it will be obvious that the cylinder and piston can only be operated if at all by a considerable force being applied to .the `piston rod and in this manner an effectivexbrake will be providedfor the reciprocating mechanism.

positively preventing movement of the-vehicle and this shoe is pivoted upon one of the bars 15 and engageable with the periphery of the disk 29 so as to prevent rotation thereof. The brake shoe is also connected, by a rod 60'rto a lever 61 upon the "rear of the casing 14 so that said shoe may be adjusted into and out of engagement with the disk 29. N
