UNITED STATES PATENT OFFICE.
DAVID KENT, OF MANCHESTER CENTRE, VERMONT.
DEVICE FOR OPERATING CUTTER-BARS.
SPECIFICATION forming part of Letters Patent No. 468,624, dated February 9, 1892.
Application filed April 24, 1890. Serial No. 349,854. (No model.)
To all whom it may concern.-
Be it known that I, DAVID KENT, a citizen of the United States, residing at Manchester Centre, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Devices for Operating Cutter-Bars, 850., of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure 1 representsa front view of a mower having my invention applied thereto; Fig. 2, a detail side elevation of the trammel, and Fig. 3 a detail view of one of the adjustable segments.
The object of the invention is to provide improved and simple means for operating the reciprocating cutter bars of mowing machines, lawn-mowers, clipping-machines, &c., whereby a very rapid motion willbe imparted to the cutter-bar withoutappreciable loss of power and the wear of the parts readily and accuratelycompensated for, as will fullyhereinafter appear.
Referring to the annexed drawings by letter, A designates a suitable horizontal shaft connected in the usual way with the driving mechanism of the mower; B, a trammel secured on the end of this shaft and having in its face the usual intersecting grooves or ways; 0 0, slides T-shaped in cross-section and adapted to work in the similarly-shaped intersecting grooves in the face of the trammel, and O a pitman pivotally connecting the cutter-bar D to the slides C, as shown. It
will be observed that when the trammel is rotated the pitman will have two full reciprocations imparted to it to every single rotation of the same, according to the well-known principles of the trammel, and whereby the cutter-bar will be rapidly ciprocated without undue evident.
To compensate for wear of the slides and grooves in the face of the trammel, I adj ustably attach the segments a, which form the grooves, to the face of the trammel by means of bolts Z), which pass through radial slots 0, in the segments. The outer curved edge of and smoothly rejar or noise, as is each segment has formed in it a radial notch or recess a, in which projects a stop 0, formed on the face of the trammel. Between the stops 0 and the inner ends of the notches are interposed screws or bolts 0', the inner ends of the screws being tapped into the segments. It will be observed that by loosening the bolts bthe segments may be readilyand accurately adjusted radially by means of the screws, as is evident. The slots a and stops 0 combine to insure the guidance of the segments while being adjusted, thereby preventing binding upon the slides.
Having claim is- The combination, in a trammel, of a disk, segments secured to the disk by screws passing through radial slots in the segments, said segments forming intersecting grooves, slides working in said grooves, a pitman connecting the slides, radial screws 0 for radially adjusting said sections, and stops for said setscrews, substantially as described.
In testimony whereof Iaffix my signature in presence of two witnesses.
DAVID KENT.
