IECHANICAL MOTOR FOR GAS-MACHINES Specification of Reissued Letters Patent. Reissued J 1y 16, 1912, I Drigilal Io. 988,321, dated January 24, 1911, Serial No. 482,152. Application for reissue filed October 10,

of Iowa, have invented certain new and useful Improvements in Mechanical Motors for .Gas-Machines, of which the following is a dull, clear, and exact description, such as will enable others skilled in the art to which it q plpertains to make and use the same.

e invention relates to mechanical movements and is designed to arrange for the convenient manipulation of a weight actuated. motor by hand, to wind up the weight by rovide for carrying a drum of the pump orward in its usual direction while the weight is being wound up, so that the opposite movementof the winding mechanism shall impart motion to the blower.

It is furthermore designed to provide automatic means by which the drum of the pump shall be carried forward by the rotation of the handle at such times only as the gessure in the gas tank shall be at a pretermined minimum.

With these and other objects in view, the

4 80 scribed and claimed, reference being had to the accompanying drawings, wherein,

Figure 1 is an end view of a motor constructed in accordance with this invention;

- and Fig. 2 is a front elevation'of the drum 86 and the ratchet wheel. 3 Like characters of reference are employed to designate corresponding parts in all the? figures of the drawings. In the drawings, the numeral 1 denotes 4c the shaft of a rotary air pump, such as is commonly employed for forcing air into and through a tank containing gasolene for the production of illuminating gas. This shaftis journaled in the outer end of a 46 cylindrical case not shown in the drawing and in the rear end ofthe supporting frame. This shaft is rigidly secured to ratchet wheel 5.

The numeral 2 denotes the windin drum which takes upon it the cord to w ich is a proper support and has its extreme outer end squared to take upon it a winding handle 15/ On its inner end the drum is journaled upon a boss 25 projecting from the ratchet wheel Formed with the inner extremity of the drum is the ratchet disk 8, concentrically disposed and adjacent to the ratchet wheel 5 and adapted to revolve in a clockwise direction when the weight is being wound up. A ratchet pawl 9 is mounted upon ratchet wheel 5 and is held in engagement with wheel 8 by means of the flat spring 10 lying within a flange 11 on wheel 5. Adjacent to the ratchet wheel 5 and loosely mounted upon shaft 7 extending parallel with the axis of the drum, is the ratchet pawl 6, cooperating with the ratchet wheel 5 and preventing the backward movement of the blower. To the lever 18. rigidly attached to shaft 7, is pivotally attached the pawl 20 and 21, which is counterbalanced at 22 and is adapted to engage the ratchet teeth on wheel 5. At the front of the mechanism and outside of frame 23, a yoke consisting of members 12 and 13 is attached to the front end of shaft 7 and hangs loosely over the squared end of shaft 4, the member 12 being rigidly attached, and the member 13 loosely connected to said shaft 7. The

minimum spread between the yoke members is equivalent to the diameter of the eccentric 14 formed with the removable handle 15. The rigid yoke member 12 is loosely clamped to the free member 13 by the bolt 16 and is held in contact therewith by the helical spring 17.

WVhen the Weight is wound u the drum 2 and its ratchet disk 8 ina counter clock-wise direction as here shown. By the action of the pawl 9 the power is communicated toratchet wheel 5, by which means theblower is slowly revolved. In winding up the weight the eccentric 14, revolving with the handle 15 and within the yoke members 12 and 13 will actuate the said yoke members alternately. Coming in contact with member 12, the said member is upwardly displaced, causing a partial r0- tation of shaft 7 to whose forward end it is secured and to whose rear end is rigidly secured lever 18 and to which pawl 6 is freely attached both pawls engaging ratchet wheel 5. This upward displacement actuating leand its gravity allowed to operate, it ten s to drive pressure in the carbureter must be main-' tained by mechanical means during the process of winding the drum. Should the resistance on ratchet wheel 5 be less than the pressure on spring 17, both yoke members act under the pressure of the eccentric 14 as an integral yoke, member 13 cooperating with member 12 to displace member 12 in a downward direction, to retract pawl 20 and with it to advance ratchet wheel 5 one or more ratchet teeth. Should the pressure in blower and carbureter be as high or higher than the predetermined minimum, ratchet wheel 5 will offer greater resistance than is represented by spring 17, which in this case will give under the pressure of the eccentric, when although the yoke member 13 will be displaced downwardly as before, the member 12 will not be so displaced, therefore although pawl 20 has been advanced by the upward displacement, it will not be retracted by a lower displacement, as member 12 will remain stationary in its upward position. In either case the winding of the drum will be continued until it is wound up and the necessary pressure main tained in the carbureter.

I claim as my invention:

1. The combination with a rotative driven member, of a rotative driving member, a pawl and ratchet connection between said driving and driven members, acting to effect rotation of the driven with the driving member when the latter is turned in one direction, and a separate driving connection between said driving and driven members for turning the driven member when the driving member is rotated in the opposite direction, embracing a pawl and ratchet mechanism and a yielding member through which motion is transmitted from the driving member to said pawl and ratchet mechanism; said pawl and ratchet mechanism acting to impart a positive, intermittent rotative motion to the driven'member and said yielding member serving to prevent the transmission of motion to the driven member when a predetermined minimum resistance in said driven member is exceeded.

2. The combination with a rotative driven member, of a rotative driving member, a pawl and ratchet connection between said driving and driven members, act-ing to effect rotation of the driven with the driving member when the latter is turned in one direction, and a separate driving connection between said driving and driven members acting to impart rotative motion to the driven member when the driving member is turned in the opposite direction, said separate driving connection embracing a spring through which motion is transmitted from the driving to the driven member and means for adjusting the tension of said spring.
