MOTOR-BALANCING DEVICE.
Application filed May 25,
To all whom it may concern:
Be it known that 1, JAMES W. TURNER, a citizen of the United States, residing at Statesville, in the county of Wilson, State of Tennessee, have invented a new and useful Motor-Balancing Device; 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 which it appertains to make and use the same.
The invention relates to mechanical motors for use in connection. with'engines of various kinds and has for its object to provide a pivoted lever pivoted at a point spaced from its ends, the upper end being connected by a pitman to a pitman disc, the lower end of the pivoted lever being provided with a weight which swings in an arc as a connecting rod which is reciprocated by an engine operates, said weight increasing the efficiency of the motor. I
A further object is to provide a pivoted lever which is oscillated on its pivotal point by an engine and to providesaid lever with weight means whereby the efiiciency of the motor will be increased.
vVith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings Figure 1 is a side elevation of the engine showing the pivoted weight carrying lever attached thereto.
F igure' 2 is a detail view of a portion of the pivoted lever and its supporting brackets.
Referring to the drawings, the numeral 1 designates a conventional form of engine and 2 a cross head carried thereby. The motor lever 3 is disposed in alignment with the crosshead 2 and is supported in bearings f of brackets 5. Lever S is braced by truss rods 6 so that the lever will not bend at the ends of the stroke. However secured to the lower end of the lever is a weight 7, which weight is adapted to swing in an are so as to increase the efliciency of the power imparted 1920. Serial No. 384,060.
to the pitman 8 which is pivotally connected as at 9 to the upper arm 10 of the lever and at 11 to a wrist pin carried by a pitman disc 12. Disc 12 may be provided with a shaft 13 so that the device may be utilized for drlvlng machinery or any other purpose. Pivotally connected as at 14 to the crosshead 2 is a connecting rod 15, the outer end of which is bifurcated as at 16 and has its arms pivotally connected as at 17 "to the lever 3 at a point between the bearings and the energizing weight 7.
It has been found that providing the weight 7 that increased power is imparted to the pitman rod 8 with the least consump tion of fuel in the engine 1 at an increased efiiciency. This being caused by the extra momentum of the pivoted lever 3 as said weight 7 swings backwardly and forwardly incident to the reciprocation of the crosshead 2. Although the weighted pivoted lever is shown in connection with the horizontal type of engine it is tobe'understood that any type of engine may be used and that the pivoted lever may be disposed in various positions, for instance as shown with its lower end downwardly extending through an elongated opening 18 in the flooring 19 so that the weight 7 may swingin such a position that it willhave freedom of action at the best possible are to obtain the best results.
From the above it will be seen that a device is provided' wherein power imparted by an engine may be at an increased efficiency.
The invention having been set forth what is claimed as new and useful is A motor balancing device comprising a pivoted lever pivoted to swing in avertical plane, the pivotal pointof said lever being adjacent theupper end of the lever, the
lower end of said lever being provided with a weight right angularly disposed and oppositely disposed arms carried by the lever adjacent its pivotal point, downwardly, outwardly and inwardly extending truss rods extending from the upper end of the lever and over the right angularly disposed arms, said truss rod being connected to the lever adjacent the weight at its lower end, a connecting rod pivoted to the leverb'etween its pivotal point and the weight and provided with a bifurcation for the reception of one of the truss rods, a motor for actuating said connecting rod, a substantially horizontally disposed connecting rod pivoted to the upper end of the lever, said last named connecting rod forming means whereby the power from the motor and the swinging lever may be utilized for driving shafting.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
