Description
i UNITED STATES PATENT OFFICEo P. H. STANDISH, OF PACHECO, CALIFORNIA.
IMPROVEMENT IN HARVESTERS.
Specification forming part of Letters Patent No. 31,490, dated February 19, 1861.
To a/ZZ whom it may concern:
Be it known that I, P. H. STANDIsn, of Pachecoin the county of Contra Costa and State of California, have invented a new and Improved Grain and Grass Harvesting Machine; and I do hereby declare that the fol-A lowing is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a front sectional view of my invention, taken in the line x, Fig. 3 5 Fig. 2, a vertical section of the same, taken in the line y y, Fig. 3; Fig. 3, a plan or top view of the same; Fig. 4, a detached sectional view of the sickle-driving mechanism, taken in the line z z, Fig. 2. f
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to certain improvements in the sickle-driving mechanism which is of that class having a serpentine cam and pallets.
The object of the within-described invention is to allow a certain degree ofplay or yielding movement to the axis of the pallets, and at the same time render the pallets easily adjustable, so that they may be readily thrown in and out of gear with the cam.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents the main frame of aharvester; B, the finger bar attached thereto C, the platform attached to the nger-bar, D, the grain-wheel at the outer end of the platform,
and E the driving-wheel in the main frame.' The above parts, being of usual construction,
do not require a minute description. The inner edge of the wheel E is of scalloped form, as shown clearly in Figs. 1, 3, and 4.
In 'the main frame A there is placed a rock-shaft, F, the back end of which is fitted in a bearing, G, which is pivoted to the main frame A, as shown at a, the pivot a' admitting of a lateral movement of the shaft F, as will be readily ,understood by referring to Fifr. 3.
On the rockshaft F there is placed a bar, H, which projects from shaft F at equal dis tances, and has a roller, b, in each end of it. This bar H and its rollers I term palletsj as they are operated by the scalloped rim of the wheel Ein the same way as the pallets of Acasual movement of the wedge.
a clock are operated upon by the scape-wheel. The front end of the shaft F has its bearing c in a boX or guide, I, which is attached to the main frame A, and a wedge, d, is inserted in the boX or guide I and secured in proper position by a pin, e, the pin preventing the d bears against a spring, f, secured in the boX or guide I. The lower end of the bar H has a bar, g, attached to it, the lower end ofi which is connected by a rod, g, to a sickle, J, which is fitted on the nger-bar B, as usual.
K is a roller, which is fitted in the main frame A, at the outer side ofthe driving-wheel E, to serve as a bearing directly opposite the pallets or rollers b b. (See Fig. 3.)
The main frame A is connected by bars h h to a frame L, which is supportedby a casterwheel, M, the drivers seat N being on frame L. The draft-pole O is attached to the standard of the caster-wheel.
The operation is as follows: As "the machine is drawn along, the scalloped edge of wheel E vibrates the bar H, in consequence of acting against its rollers b b, and a reciprocating movement is communicated'to the sickle J through the medium of the bar g and connecting-rod g. The spring f prevents any v undue strain, either of bar H or shaft F, for
the spring admits of a yielding movement of the shaft, and as the roller Kserves as a bearing for the wheel E the latter is prevented from binding on its axle, and the driving mechanism is allowed to operate with but little friction.
The sickle may be raised and lowered to the desired height by means of a-lever, I), as shown in Fig. 8. This, however, has been previously used, is well known, and does not require a particular description.
I do not claim, broadly, a scalloped cam or driving-wheel in connection with pallets or a rock-bar, as such device is quite old; but
I do claim as new and desire to secure by Letters Patent- The arrangement of the spring f, wedge d, and guide I with the Yframe A, shaft F, palletbar H, and scalloped wheel E, in the manner and for the purposes herein set forth.
