HAY=LOADER.

SPECIFICATION forming part of Letters Patent No. 271,470, dated January 30, 1883. Application filed June 24, 1882. (X0 model.) i

To all whom it may concern:

Be it known that I, DEWITT U. Jnwnr'r, a citizen of the United States, residing at Sand Spring, in the countyof Delaware and State of Iowa, have invented certain new and useful Improvements in Hay-Loaders; and I do hereby 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 appertains to make and use the same.

This invention relates to that class of hay rakes and loaders having one or more reciprocating rake-frames which operate to gather the loose hay from the ground and carry it up over an incline into the wagon to which the loader is attachedsuch a hay rake and loader, for instance, as is described in United States Letters Patent No. 217,l10, granted to me on the 1st day of July, 1879.

The object of this invention is to improve the construction and operation of the machine described in my United States Letters Patent above referred to; and to this endtheinvention consists in certain particular features of construction, and in the combinations arisingfrom their co-operation,which will be fully described in the ensuing specification, and particularly set forth in the claims at the close thereof.

For a full understanding of the construction and operation of myimproved loader, reference should be had to the accompanyingdrawings, wherein Figure lis a side elevation of the loader. Fig. 2 is a vertical section thereof. Fig. 3 is plan view; and Fig. 4 is a sectional detail, showing the lower portion of one of the rakebars.

The same letters of reference indicate identical parts in all the figures.

The frame A of the incline is provided on each side rail of the machine with a pair of stout bars, A A extending downward and toward each other, and terminating at their meeting point, where suitable bearings are fitted for the wheel-axle B, which is adapted to be revolved by the forward movement of the wheels B, each of which is to this end provided with spring-pawls b, which engage with ratchet-wheels I), rigidly secured .to the axle.

The arrangement of the pawls and ratchetsis such that the axle will only be revolved upon the forward revolution of one or the other of the wheels, thus making provision for the turning of sharp corners or backing.

Between the ratchets b a bolster, B is secured upon the axle by suitable means, and to this bolster the tongue 12 and hounds b 3113 rigidly secured. The hounds b extend some little distance to the rear of the axle and bolster, and are provided at their ends with springs b the upper ends of which are secured to the frame A of the incline, and tend to keep the rollers or shoes a at the rear end of said incline pressed upon the ground with a yielding pressure, in a manner similar to that stated in my patent before mentioned.

I also provide in this machine a stout bar, I), projecting upwardly from the tongue for the forward part of the frame to rest upon while the machine is being transported from place to place, and form ayielding connection between the frame A and the tongue by means of the springs I), as shown.

To each side rail of the frame A is fulcruuied a horizontal lever, O, and to the forward end of such lever U is fulcrumed a vertical lever, G, the lower end of which is secured, by a-strap or other suitable means, to a stud projecting from a crank-arm, B fixed to each end of the axle B.

To the upper end of each vertical lever U is secured one end of a pitman, c, the other end of which is connected to the lower cross-bar, d, of the rake-frame D. This crossbar is provided at each end with a roller, 62, which travels on a track or way, F, pivoted at its forward end to a suitable post, and having guide-railsf at each side of the roller. These tracks or ways F are connected by pitmen G to the horizontal levers C at a point between their fulcrums and forward ends, as shown.

The rear ends of the horizontal levers C are connected by means of pitmen c to the lower cross-bar, c, of the rake-frame E, and this lower cross-bar, c, is also connected with the crankarms B by means of pitmen e.

The upper cross-bars of the respective rakeframes are provided with rollers (1 0 which travel on fixed ways a, and on the overhung ends of the cross-bar e are pivoted arms h of a supplementary rake-frame, H, which arms h travel on rollers a mounted on studs projecting from the side rails of the frame A.

The rake-teeth I, as constructed for my improved maehine, are formed of a single piece of wire bent so that the point 1' stands at an obtuse angle with the shank t". The points are passed through and play vertically in mortises cut in the longitudinal bars of the rake-frames, and the eyes of the shank i are secured to the top of such longitudinal bars, by staples or other suitable devices, in such manner as to give the teeth considerable vertical play at their points, as shown in Fig. 4. The rear ends of the longitudinal bars of the rake-frames are provided with shoes, each having two raketeeth secured to and projecting through them, said shoes being fitted with a spring tail-piece, as shown.

The operation of my improved hay rake and loader is as follows: The tongue I) having been secured to the rear end of the wagon to be loaded, the wagon is movedacross the field,

the rotation of the wheels B causing the 1-0 tation of the cranked axle, which gives an oscillatory and vertical movement to the vertical levers O. The oscillatory movement of these levers causes the backward and forward travel of the rake-frame I) over the incline to feed the hay upward. The rear end of this rakeframe 1), during its forward movement, travels close to the incline, as shown in the drawings; but during its backward travel it will be raised from the incline in consequence of the lifting of the rear ends of'the pivoted tracks F by means of the horizontal levers (l and pitmen (Jr. These pitmen have considerable play at their points of connection with levers O to provide against the breakage of any of the parts in the event of a wad or roll of hay becoming lodged upon the incline at the moment the rake-frame is to descend. The pitmen 0 cause a similar backward and forward travel of the rake-frame lfi, which is also caused to rise and fall at its rear end in consequence of its connection, through pitnien c, with the rear end of the horizontal lever U. The forward ends of these rake-frames travel in one and the same plane, being both guided by the track a.

It will be seen that by reason of the arrangement of levers and pitmen for operating the rake-frames the movement of one will be the reverse of the movement of the other, so that while one is moving forward close to the incline the other is raised from the incline and moving backward.

The supplementary rake -frame H is designed to'take the hay from the top of the incline and thrust it forward onto the wagon. It may be folded back upon the rake-frames D and E during the transportation ofthe machine from place to place.

The rake-teeth operate in a manner similar to the movable ones described in my former patent, and I therefore do not deem a particular description of their operation necessary in this specification.

Having thus described my invention, what I claim is 1. In a rake-frame for hay-loaders, the combination, substantially as before set forth, of the longitudinal bars provided with mortises, and the rake-teeth loosely secured at their shank ends to the top ofand havingtheir point ends protrude through to the lower side of said bars through the mortises cut therein.

2. The combination of rake-frame D, having a cross-bar, (I, the pivoted tracks, the crankaxle, and means controlled by the cranked axle for simultaneously operating said rake-frame and tracks, substantially as before set forth.

3. The combination, substantially as before set forth, of the rake-frame E, having a crossbar, 6, pitmen e, horizontal levers (J, and pitmen 0.

t. The combination, substantially as before set forth,of the incline, the reciprocating raketrames D and E, and the supplementary 1eciprocating rake-frame.

In testimony whereof I atlix my signature in presence of two witnesses.
