SPECIFICATION forming part of Letters Patent No. 610,200, dated'September e, 1898'. Application filed November 5,1397. Serial Noe57,615. (No model.)
To all whom it may concern.-
Be it known that I, OLIVER B. PICKETT, a citizen of the UnitedStates, residing at Richmond, in the county of WVayne and State of Indiana, have invented certain new and useful Improvements in Lawn-Mowers; and I do 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 ap pertains to make and use the same, reference being had to the accompanying drawings, and to the figures of referenoemarked thereon, which form a part of this specification.
This invention relates to improvements in lawn-mowers.
The object of the said invention is to provide means for conveniently adjusting the cutting-blades with relation to each other and to obtain an exact andminute adjustment.
As preliminary to a detailed description of the invention reference is made to the accompanying drawings, of Which- Figure 1 is a plan view of a lawn-mower having my improvements thereon. Figs. 2 and 3 are enlarged elevations of the side plates, showing the opposite sides thereof. Fig. 4 is a sectional view on the line a: w of Fig. 2. Fig. 5 is a detached view of one of the bearing-plates for the shaft of the rotating blades. Fig. 6 is a section on line y 'y of Fig. 2.
Throughout the specification similar reference characters indicate corresponding parts in the several views.
The invention is embodied in the side plates 1 1, which are connected by the usual transverse rod 2 and which support the groundroller 3, the stationary blade 4, and usually the shaft 5 of the rotating blades 6; but in the present instance these side plates do not support the shaft of the cutting-blades 6, as will hereinafter more fully appear. The ground-wheels 7 7 are mounted on hollow stub-shafts 8, that project rigidly from the inner sides of the said plates. Adjacent to these stub-shafts each of the said side plates has an oblong opening 9, or an opening which narrows inwardly and which is essentially larger than the shaft 5 of the rotating blades in order to admit of the said shaft receiving the adjustments in a manner hereinafter described.
10 designates bearingplates for the ends of the shaft 5 and which have a loose bearing on bosses or annular projections 11 on the outer side of the side plates 1 1. The said bearing-plates 10 are mounted with the journal openings 1Q therein over or in line with the openings 9 in the side plates. The outer ends of the side plates are provided with vertical housings or recesses 13 and 14, standing one above the other in line, with their hollow sides facing inopposite directions, as is shown in Fig. 4. These recesses constitute keepers for a verticallymovable adj usting bolt 15, which has a nut 16 on its middle'portion. Thereis an open space between the inner terminals of the recesses or housings 13 and 14, in which this nut is confined, and on each side of the said nut or the space which the nut occupies there are openings 17 17, which permit of the insertion of a wrench to turn said nut to lower or elevate the bolt. The upper end 15 of said bolt terminates on an angle and is projected outwardly through an opening 18 on the outer end of the plates lO. The inner sides of the ends of said plates in which the openings18 are are hollowed out to fit over the rounded form of the bolt. It will thus be seen that these bearing-plates 10 10 are movable in a slight arc according to the movement given the adjusting-bolt 15, and a very minute adjustment maybe given the rotating blades with relation to the stationary blade,the adjustment being obtained through the means and in the manner just described. The bearing-plates 10 may be firmly secured in their adjusted position by a lockin g-bolt 19, that passes through each of the side plates 1 and the bearing-plates 10 at right angles to the adjusting-bolt 15. The inner ends of the bolts 19 each has a head 20, that fits against the inside of the plate 1, and the said bolts pass through a bolt-hole 21 in each of the side plates and through an oblong vertical slot 22 in each of the bearing-plates 10. The slots 22 in the plates 10 permit of an arc adjustment of said plates through the adjusting-bolt by loosening the nut 23 on each of said locking-bolts. The said nuts are tightened to lock the plates in their adjusted positions.
The handle of the lawn n10wer, which is not shown, is attachable in the usual way to the plates 1 by pins 24 between pins 25. Thejournals of the ground-roller 3 are mountable in openings 26 in the side plates, and the stationary blade 4 is fixed to said plates in openings 28. The reel or rotating blades are driven in the usual manner.
Having described my invention, I claim 1. In a lawn-mower, the combination with the side plates each of which has the vertical recesses 13 and 14: on opposite sides with an intervening opening 17, and an adjacent opening 21, of a bearing-plate 1O pivoted to each of said side plates and adapted to support the shaft of the cutting-reel, the said bearing-plate having a vertical slot 22, and an opening 18 on its outer end, a bolt lying in said recesses 13 and 14 with its upper end projected into the opening 18 in the bearingplate, whereby an arc movement may be imparted to the bearing-plate, and means for securing said plate in its adjusted position, substantially as shown and described.
2. In a lawn-mower, the combination of side plates having openings therein for the ends of the shaft of the rotating blades to project through, and vertical recesses with their concaved sides facing in opposite di- OLIVER B. PIOKETT.
