UNITED STATES PATENT OFFICE.
FRANK `LA BATT, OF EASTON, EV YORK.
LAWN-SWEEPER.
SPECIFICATION forming part of Letters Patent No. 435,144, dated August 26, 1890. j
Application filed March 22, 1890. Serial No. 344,897. (No model.) Y
To a/ZZ whom, t may concern:
Be it known that I, FRANK LA BATT, a citizen of the United States, residing at Easton,
county of Washington, and State of New York,
have invented certain new and useful Improvements in Lawn-Swecpers, of which the following is a specification.
My invention relates to such improvements; and it consists of the novel construction and combination of parts'hereinafter described, and subsequently claimed.
Reference may be had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiicaiton.
Similar letters referto similar parts in the several gures therein.
Figure l is atop plan view of my improved lawn-sweeper. Fig. 2 is a side elevation of same. Fig. 3 is a central vertical section taken on broken line 3 3 in Fig. l.
A is the box-frame open at the top, and provided at the rear end with the operating-handles A. The drive-wheels B are tixed upon the drive-shaft B which has its bearings in the side walls of thc frame. The side walls also support the transverse rollers B2, B5, B", and B5, and the brush-shafts C and C', all of which rollers and shafts have their bearings in such side walls. The rollers B2 and B3 support the endless belt or apron O2, passing around such rollers, and the rollers B4 and B5 support a similar endless apron O5. The rollers are so located that the aprons occupy an inclined position near each other and extend from the lower part of the front end of the machine to the upper part of the rear end of the machine over the box or chamber C". he bottoinA2 of the frame extends downward to the front under the lower roller B5, terminating in an inclined wedge-shaped table and scraper A3, with a rear abutment which partially surrounds roller B5 and serves as a protecting-guard for the apron C3 as it passes around the roller B5. The upper apron does not extend so far to the front as the lower one, thereby forming an extension A" oi' the table A5. The rotary brush-shaft O is located at the forward end of the table, and when rotary movements are communicated to it in the dileaves and grass lying upon the ground, repwhich point the objects will fall by gravity into the chamber O4. In case any portion adheres to the upper apron after leaving thelower apron it will be removed by the revolving brush C', located at theend of the upper apron and revolving in the direction'ot' the arrow. The required movements are communicated to the brushes and aprons by a single sprocket chain passing over the driving sprocket wheel or rim D', fixed upon the spokes of one of the drive-wheels, as by the studs D2 (shown by solid lines in Fig. l and by dotted lines in Fig. 2) around the lower side of the small sprocket-wheel D3, iixed on the brush-shaft O, over the sprocket-wheelD4, fixed upon the roller B4, under the sprocketwheel D5, xed upon the roller B2, around the sprocket-wheel D5, fixed upon the brush-shaft l C', and backover the sprocket-wheel D5 to the sprocket-rim D. The chamber O1 is provided with a door. A5, hinged at A5', and held in a closed position by a catch AS. The contents of the chamber can be discharged therefrom by releasing the catch and lifting' upon the handles A. A wheel F, having its bearings in brackets F secured centrally of the lower side of the frame, servos as a fulcrum when the handles are depressed to lift the drivewheels from the ground in passing over obstacles inthe path of the sweeping-brush or as means for transporting the device without actuating the brush or aprons, or for turning the device around to be propelled in any desired direction. When desired, the wheels F may be provided of any required size;
My improved device is especially adapted for sweeping up and carting away dead leaves. As the leaves pass between the two aprons they are compressed and forced into the receiving-chamber. The upper apron also serves to prevent the wind from blowing the leaves away when raised from the ground by the sweeping-brush.
Vhen the nature of the material to be sweptv IOO up is such that the brush upon shaft C is not necessary to remove it from the upper apron, such brush may be dispensed with, the sprocket-chain passing around the sprocketwheel D5.
What I claim as new, and desire to secure by Letters Patent, is-
l. In alawn-sweeper, the combinatiomwith the main frame, of traction drivewheels, a rotarysweeping-brush, two conveyi rig-aprons, one above the other, mounted upon transverse :rollers and contiguous and parallel to each other throughout the major part of their length, the lower one extending beyond the upper and into the curved abutment of the scraper, a receiving-chamber, and means for connecting the apron-rollers and brush-shaft with the drive-wheels for communicating rotary lmovements thereto, substantially as described.
2. In alawnhsweeper, the combinatiomwith the main frame, of traction drive-wheels, a rotary'sweepin-g-brush, two eonveyingaprons, one above land contiguous and parallel to 'the other, 'mounted upon rollers, a receiving-table consisting of a fixed shelf, and the front part of the lower apron interposed between the Sweeping-brush and the front roller of the upper apron, said apron extending beyond the lower at the rear, a receiving-chamber beneath the rear apron-supporting rollers, and means for connecting the apron-rollers and brush-shaft with the drive-wheels for communicating rotary movements thereto, substantially as described.
3. In a lawn-sweeper, the combination,with the main frame, of traction drive-wheels, a r0- tary sweepingbrush, two parallel conveyingaprons, one above and contiguous to the other, mounted upon transverse rollers, the apron extending farther to the rear and the lower farther to the front than the other, respectively, a receivingchamber, a rotary brushshaft C', located over the chamber parallel with and contiguous to the rear upper apronf supporting roller, and a single sprocket-chain connecting the sprocket-wheel fixed to revolve with the drive-wheels, and sprocket-wheels. fixed, respectively, upon the sweeping-brush shaft, one of the supporting-rollers of each apron, and the brushshaft C', substantially as described.
In testimony whereof I have hereunto set my hand this 17th day of March, 1890.
