MECHANICAL MOVEMENT.
To all whom it mag concern:
which is the principal object of this invention.
In this specification and the annexed drawings, the invention. is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by'the claims following this description it is desired to cover the invention in whatever form it may be embodied.
mgs:
Figure 1 is a side elevation of a toy velocipede, partly in section, having this invention applied thereto, as a propelling means. I Fig. 2 is a fragmentarydetail in side elevation, of the traction element.
Fig. 3 is a front elevation of the same partly in cross section.
Fig. 4 is a detail of the frictional joint between the extension and connecting rod.
In detail the embodiment of this invention illustrated in the drawing includes the main frame 1, having the transverse axle tree 2, indicated in dotted lines, at the rear and the jointed steering post 3 swiveled tothe frame l. The post3 is the base for the operative parts. The main frame 1 is pivotally held in the U bracket 4 by the king bolt 5 extending'therethrough. The bracket 4 is rigidly secured to the steering post 3 by rivets or by any other suitable means. The front wheel 6 is journaled in the steering post 3 and the rear wheels 7 are suitably journaled on the axle 2, secured to the axle tree 2, forming a three-wheeled vehicle or velocipede.
The seat 8 for the rider is'fixed to the upper endof the supporting post 9 which is adapted to enter the holes 10 formed through the backbone 1. The supporting post 9 is holes 11.
In the accompanying one sheet of draw- Specification of Letters Patent. Patented D 30 1919 Application filed February 4, 1918. Serial No. 215,350. I
provided with a plurality of spaced holes 11 which are adapted to aline with companion holes 12 formed on the sides of the holes 10 in the backbone 1. The pin 13 is provided to extend through the alined holes 11 and 12 and hold the post 9 in place. It is obvious that any adjustment of height of the seat 8 can be obtained through the series of spaced The hole 10 permits the seat 8 being moved closer to the steering post 3 in the event that the seat 8, as positioned in the opening 10, does not adjust itself to the rider.
Above the backbone 1 the steering post 3 I is divided to-form the handle lever 14. The
The plates 15, on the handle 14, are provided with'an extension 20 preferably an integral part thereof. The connecting rod 22 is frictionally pivoted to the extension 20 by the pivot 24. The holes 25 25 are provided in the extension-2Q for adjustment of the-leverage ratio of the connecting rod 22. The lower end of the connecting rod 22 terminates in the rack 26 engaging the ratchet or pinion 27 fixed on the front wheel 6, which rotates on the axle 28 fixed in the steering post 3. The supplementary rack 29 having the teeth thereof oppositely disposed to the teeth of the rack 26, is formed on an extension 30 of the connecting rod 22 in juxtaposition to the rack 26 on the opposite side of they ratchet, 27. The extended axle 28 forms foot rests 32-32 for the feet of the operator for his comfort, also providing auxiliary means for steering the front wheel 5 by means of the feet of the operator.
To reduce friction the roller bearing 33 is interposed between the wheel 6 and the axle 28. The ratchet 27 is preferably formed integrally with the sleeve 34 of the roller bearing which in turn is fixed in the wheel 6 to rotate therewith. The anti-frics which under the influence of. the side fric- -flat connecting rod tion rollers 33- are interpose didirectly tween the sleeve 34 and the bushing as shown in Fig; 3.,
: is provided between the extension 20 [and the connecting rod 22, for reasons which will hereinafter appear. Y v This invention operates substantially as follows: I
A forward pushon thegrips '19 by the operator swings the propelling lever 14 forward This horizontal movement of the lever 14 results in .a vertical arcuate .movement of the extension lever 20, the rise and fall of which raises and lowers the connectingrod22, The depression of the con- .necting rod 22 and the rack 26 thereon causes the rack 26 to rotate the ratchet gear 27 in a clockwise direction (seefFig. 1).
This rotation of the ratchet 27 continues during the forward movement of the handle 14 and the length of the rack 26' until the bottom of the extension 20 engages the stop screw 36 which arrests its-downward movement. Therotation of the ratchet gear 27' has rotated the front wheel 6, which acting as a traction wheel, drags the velocipede for.-'
ward. The return or back movement of the handle v14 elevates the connecting rod 22 tion the pivotal joint 24 swings forward breaking the engagement between the rack 26 and the ratchet gear with the rear p'eriphcryof the'ratche't gear 27. Theupward movement of the connect ing rod 22 causing this supplementary rack 29 to continue torotate the ratchet gear 27-; in the forward or clockwise'direction, whereby the reciprocating \arcua'te movement of the propelling lever 14 raises and lowers the connecting rod alternately throwing the rection', thereby transmitting the recipro eating; movementto a I continuous rotary movement in a single direction.
While this invention has been described and illustrated in connection with its particular application to velocipedes, I do not wish to be understood as confinin g it thereto;
Many variations within the purview of this i so practice of this art.

3. Means for propelling a vehicle 'comprising a revoluble traction wheel on said vehicle; a pinion fixedon said wheel; opposed racks on opposite sides of said pinion and held in fixedrelation; a lever pivoted on said vehicle; and a rigid connection to wheel secured to said traction wheel; racks on the opposite sides of said ratchet wheel adapted to alternately engage said ratchet; a handle pivoted .to said steering post, piv otal. means connecting said h' amd le and racks whereby lateral movement of the handle alternately-throws said racks into engagement with the ratchet whereby the reciprocating movement of the racks is transmitted to-the ratchet in a continuous rotary movement in av single direction; and a wheeled supporting body swivelly connected to said steering post.
