Description
UNITED STATES PATENT OEEIoE.
GEORGE T. SAVERY, DEGEASED, OF NEWBURYPORT, MASSACHUSETTS; N. JENNIE SAVERY, ADMINISTRATRIX, ASSIGNOR TO JOHN N. PIKE, OF
SAME PLAGE.
Specification forming part of Letters Patent N0. 111,258, dated January 24, 1871.
To all whom it may concern:
Be it known that I, GEORGE T. SAVERY, of Newburyport, in the count-y of Essex and State of Massachusetts, have invented a new and useful Improvement in Mowing-Machines, of which the following, when taken in connection with the accompanying drawing, is a full and exact specification.
My invention relates to the combination and arrangement of a drivin g-wheel, with frictionrollers therein, acting upon an oscillatin g shaft by means of tappets, and imparting the necessary motion to the cutters by means of a jointed connecting-rod, a vibrating' lever, and a pitman, arranged as below described.
The object of my invention is to multiply the motions of the cutters without the use of cogs.
In the accompanying drawing, Figure l is a sketch of a mowing-machine embodying my invention. Fig. 2 is a detached view of the driving-wheel, with the oscillating shaft in its place, showing the act-ion of the friction-rollers upon the tappets.
a is the large wheel, constructed as usual. b represents the cutters. c is the frame of the mower. p is the axle. d is the driving-wheel, turning with the large wheel a. c e are friction-rollers in the drivin g-Wheel d, set near its edge and at right angles with its circumfen ence. g is an oscillating shaft, moving in the frame c, and supplied with tappet-s h1 h2. nl n2 is a jointed connecting-rod, with one end set irmly in the oscillating-shaft g, and the other end, by means of a pin, in the vibrating lever m. The motion is given to the cutters by the plitnian lr. o is the joint in the connecting-rod n n2.
In practical operation my machine works as follows: As the driving-wheel el revolves, of course the tappets h1 h2 are constantly striking and running over the friction-rollers e. When the-tappet h1 is about to strike africtionroller the joint o is elevated by the action of the oscillating shaft g to its highest point. As it strikes, the joint o is forced down until the jointed connecting-rod forms a straight line,
as in Fig. 1, causing the cutters b to make' one cut. As it runs over the roller the joint o is forced down to its lowest point, causing the cutters b to make a second cut. The tappet h2 is now ready to strike a friction-roller. As it strikes, it forces the joint o up to the position shown in Fig. l, causing the cutters b to make a third cut. Then, as it runs over the roller, it forces the joint o up toits highest point, causing the cutters b to make the fourth out or motion. The tappet L is then ready to strike another friction-roller.
Thus it will be seen that, if I use nine friction-rollers I canse the cutters b to make thirtysix motions or cuts, multiplying the motions fourfold without the use of cogs or gear.
Having thus fully described my invention,
what I claim, and desire to secure by Letters Patent, is- The combination of the driving-wheel, the oscillating shaft, the jointed connecting-rod, vibrating lever, and pitman, all these parts being constructed, arranged, and opera-tin g as described.
GEO. T. SAVERY.
