COMBINED HAY SWEEP AND TEDDER- SPECIFICATION forming part of Letters Patent No. 333,917, dated January 5,1886.
Application filed July 2, 1885. Serial No. 170,457. (No model.)
To all whom, it may concern.-
Be it known that I, THOMAS S. BROWN, of the city of Poughkeepsie and State of New York, have invented a new and useful Improvement in Combined Hay Sweepers and Tedders, of which the following is a specification.
The object of my invention is to provide a machine by which hay or straw may be raked or gathered into a windrow or into a pile at the center of the area swept by the machine, or by which formed windrows may be turned over; and, generally stated, it consists of a main frame mounted upon and supported by two wheels and provided at its under side with a circular tooth-frame carrying sweeping-teeth and adapted, by suitable mechanism, to be revolved as the machine is moved forward, as is hereinafter more particularly described.
In the drawings, Figure l is a rear view in perspective of my invention. Fig. 2 is a top plan view of part of the main frame and of the tooth-frame, and of devices by which the teeth are caused to press upon or be lifted from the ground. Fig. 3 is a top plan view of part of the platform, thills, and devices by which the platform and thills are connected together. Fig. 4 is a side elevation of the parts shown in Fig. 3. Fig. 5 is a rear elevation of parts of the divided axle and of the universal joint by which said parts are connected, and of the devices which support the tooth carrying frame, and of the mechanism by which said frame is caused to revolve. Fig. 6 is a view in perspective showing the switch by which the teeth of the machine are caused to be brought into or out of contact with the ground.
A is a rectangular main frame having a forward projection, B, which constitutes the platform of the machine, and upon which the drivers seat B is mounted. This main frame is supported by the divided axle F F, upon which the supporting-wheels G are loosely mounted. The divided axle F F is at its center coupled or connected by a universal joint, H, and has its bearings in blocks E, E, E, and E, which are respectively housed in frames D D D D, rigidly attached to the main frame and provided with set'screws G G G G, which rest upon and abut against the upper surfaces of the axle-blocks. The axle is at its outer extremities provided with ratchet-wheels K, rigidly attached thereto, and the supportingwheels 0 are provided with pawls L, attachedthereto, the construction of these parts being such that in the forward revolution of the supporting wheefs the pawls engage with the ratchets and revolve the divided axle in the direction of the moving machine. In the backward revolution of the supportingwheels the pawls become disengaged from and slide over the ratchets with the result that the axle remains stationary. One section of the di' vided axle, at its inner extremity, is provided with a bevel-wheel, I, which gears into a pinion, J, mounted upon and attached to the upper extremity of a vertical shaft, Q. provided at its lower' extremity with a hub, P, which carries the spokes of the circular tootlrframe or wheel,of which frame M and N, respectively, are the outer and inner rims, and O Othe toothshafts. The shaft Q is supported iii-and by a collar, Q, attached to the main frame A. The tooth -frame is provided with supplemental radial tootlrshafts It, the extremities of which are pivotally supported in the outer and inner rims, M and N, respectively. These shafts, at their inner extremities, are each provided with a vertical crank, T, which carries at its upper extremity a roller, T. The raketeeth S are intermediately of their length coiled about and attached to the shafts R R, from which the working ends of the teeth depend.
To the under side of the main frame A. there is attached a semicircular and approximatelyhorizontal track or way, U, so constructed and arranged that the rollers T of the tooth-shaft crank may, when necessary, be caused to run under and in contact with its lower surface, with the result that the teeth carried by that half of the circular tooth-frame which is at a given time toward the forward part of the machine are caused to be forced upon the ground by reason of the tooth cranks being thrown downward in the direction of the free or sweeping ends of the teeth. cranks are, as shown in Fig. 2 at T, maintained in this depressed position during the travel of the respective tooth-shaft rollers under and in contact with the track U, after which the coiled springs on the tooth-shafts assert themselves and cause the tooth-cranks to again assume vertical posit-ions, as shown in Fig. 2 at T.
The tooth-' In Fig. 6, U is a switch horizontally pivoted to the track U, at the left side of the machine, the free end being held in an elevated position by a bolt, U, when the machine is in operation, whereby the tooth-crank rollers T are guided and caused to travel under said track.
\Vhen the machine is not in use, the switch U may be dropped to a position below or on line with the track U, and there secured by the bolt U", whereby the tooth-crank rollers T are caused to travel upon the upper'surface of said switch U, with the result that all the teeth of the tooth-frame are supported above and out of contact with the ground. The thills \V are pivoted to the main frame A at X, the rear ends of the thills being pivotally attached to rods B, which slide vertically through blocks or sleeves 1V, above and below which are placed cushioning springs I).
To the block or sleeve A is pivotally attached the. lower forked arm, Z, of lever E, which is fulcrumed upon a block, 1 sprung from the platform I This lever is provided with an ordinary spring-latch and stop, E, by which the lever can be fixed at desired positions. The forked levers Z Z at the respective sides of the platform are connected to and by a shaft, Y. The thills are connected to the main frame at that side of the center of the axle at which the ral ing-teelh, when in contact with the ground, exert a draft in opposition to the forward movement of the machine, as is shown in the drawings, whereby a side pressure and movement of the thills is, in the operation of the machine, prevented.
V are rollers attached to and depending from the main frame and adapted to come into contact with the upper surface of the inner rim, N, of the tooth-wheel to steady its movement and prevent strain upon its supportingshaft Q. A similar wheel is provided at the forward part of the machine, to assist in performing the same office.
Such being the construction of my machine, its mode of operation is as follows: The circular tootlrcarryiug framehaving been adj usted at a suitable distance from the ground by the set-screws G- l G G, and the main frame having been tilted by the lever E so thatthe forward part of the tooth-carrying wheel has been adjusted sufficiently close to the ground, and the rear part of said tooth-carrying wheel has been adjusted at a distance sufficiently remote from the ground, the machine is driven forward, and the pawls of the road-wheels caused to engage with the ratchet-wheels on the extremities of the divided axle and to revolve the same, whereby, through the instrumentality of the bevel-wheel I and the pinion J, the tooth-carrying frame is revolved from the left side of the machine toward the right side, the teeth of the forward part of the toothcarrying frame being in close contact with the ground, and the teeth of the rear part of said frame being out of contact with the ground with the result that the hay or straw is swept into a windrow parallel with the direction of travel of the machine and at the right side thereof.
It will be understood that this machine may be driven round the outer edge of a circle or proper adjustment of the switch U, causing the tooth-crank rollers to travel upon the upper side of the track U.
Such being the construction and mode of operation of my invention, I claim- 1. In a hay sweeper and tedder, in combination, a main frame supported upon sup porting-wheels, a horizontal circular toothframe supportcd'eu said main frame and provided with sweepingteeth, and means, substantially as described, to revolve said toothframe in the forward movement of the machine, as and for the purpose specified.
