MECHANISM FOR CONVERTING MOTION.
SPECLIFICATION forming part of Letters Patent No. 330,622,6ated November 17, 1885.
Application filed May 7, 1885. SerialNo. 164,666.
To all whom it may concern..-
Be it known that I, SOLOMON O. RHODES, of Bradford, in the county of McKean and State of Pennsylvania, have invented a new and Improved Mechanism for Converting Motion, of which the following is a full, clear, and exact description.
The object of my invention is to provide a new and improved mechanism for converting reciprocating into rotary motion, and which mechanism is so constructed that a crank can be used with a piston having a stroke which is less than double the length of the crank.
The invention consists in parts and details and combinations of the same, as will be fully described and set forth hereinafter.
Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure is a side view of my improved mechanism for converting reciprocating into rotary motion.
The piston-rod A is secured on a piston working in a cylinder, B, and to the free end of the said rod a link, 0, is pivoted, which is also pivoted to a pitman or connecting-bar, D, at a short distance from its end. A lever, E, is pivoted to the end of the crank F, and to the other end of the said lever a connecting-bar, G, is plvoted,which has its other end mounted on a pin or pivot, H, projecting from a standard, J, and on the same pivot the upper end of a bar, K, is pivoted, the lower end of which is pivoted to the inner end of the pitman or connecting-bar D. The front end of the pitman or connecting-bar D is pivoted to the lever E a short distance from the crank-pivot, which is at the end of the lever E. The bars D E G K form a parallelogram which has different positions, one of which is shown in broken lines. By pivoting the pitman to the lever E some distance from the (N0 model.)
pivot on the end of the crank the effect of the stroke is increased, and a crank can be used which is longer than half the length of the cylinder. Theinner end of the pitman rocks on the pivot H by means of the bar K, and the bar G prevents the pitman D swinging the lever E without acting on the crank F. The standard J has two or more bearings at different elevations for the pivot H. By lowering the pivot H the effect of the stroke on the crank is increased, so that a still longer crank can be used with and requiring a longer stroke of the piston.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination, with a piston, a cylinder,and a shaft having a crank, of a link pivoted to the piston-rod, a pitman pivoted to the link and to a lever pivoted to the crank, and having its upper end pivotally connected with a standard, and of a rocking bar on the standard, the lower end of the said rocking bar being connected with the rear end of the pitman, substantially as herein shown and described.
2. The combination, with the cylinder, piston, pistonrod, and the crank F, of the standard J, having several bearings, the pivot H, the rocking bars G K on the same, the lever E, connecting the end of the bar G with the crank, the pitman D, pivoted to the lever E a short distance from the crank-pin, the rear end of the pitman being connected with the lower end of the bar K, and the link (3, connecting the piston-rod with the pitman, substantially as herein shown and described.
SOLOMON O. RHODES.
