COMBINED HAY RAKE AND LOADER.

SPECIFICATION forming part of Letters Patent No. 259,632, dated June 13, 1882.

Application filed August 11, 1881.

To all whom it may concern:

Be it known that I, GEORGE F. Scott, a citizen of the United States, residing at Independence, in the county of Oakland and State of Michigan, have invented a new and useful Combined Horse-Rake and Automatic Loading-Machine, of which the following is a specification.

My invention relates to performing in one operation those of raking and loading; and the object is to so connect a horse-rake with the hay or receiving wagon, through the medium of an endless revolving apron, as to secure the result. I attain this end by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of machine. Fi g. 2 is an enlarged view of the clutch, spring, and disengaging-lever connected with hub of rake-wheel. Fig. 3 is a sectional view of hub, axle, and connecting devices at dotted line no 00, Fig.2.

Similar letters refer to similarparts throughout the several views.

A A is a horse-rake with a bent axle, B. The inside portions of hubs Z are extended about eight inches inside of spokes, and turned to leave a shoulder about three inches from same, against which the driving-pulleys or sprocketwheels 0 0 fit. These are free wheels, about one foot in diameter, and are held in place by the ends of the feather-keys a a, the bore of the pulleys or wheels having a suficient annular enlargement at that edge to allow a free bearing. These feather-keys are intended prim aril y to secure the clutch-rin gs Z) Z) to the hub of rake, while permitting a lateral movement, so that they may engage with or be disengaged from the hubs of the sprocket-wheels or pulleys G G, which have counter-clutches, thus compelling them to revolve with the hub of rake-wheel when engaged or remain free when disengaged.

0 care spiral springs around the hub, which press the clutches b b in place when engaged, and rest against rimfianges which project sufiiciently for that purpose at the ends of the hubs.

d d are vibrating levers, which are freely pivoted to small arms a n, attached to upright portions of the rake-axle, andwhich disengage the clutch-rin gs from the hubs of sprocket- (No model.)

wheels 0 O by means of the pins or nibs c c, and which operate when the rake-teeth are lifted out of the way by the lever H, as when in turning, or whenever it is desired to suspend the raking while the machine is moving.

When the rake-teeth are drawn fully up the lever H engages with a striking plate or hook, t, which holds it secure. This is operated by means of the cord j, which is an endless one, or its equivalent, passing through a hole in top of lever H, and through a pulley, k, secured to ahigher part of the axle near the bend, and thence to the operator. This cord has a knot or button, g, outside of lever, and too large to pass the hole. This knot is intended to operate in detaching the lever from the hook by springing it toward the pulley k by drawing on the cord from that side.

D is the rake-head, of wood, into which the rake-teeth E E E are fastened. It is secured in the usual way by metal boxes fastened to the upright portions of the axle, seven or eight inches above the center of the hub.

F F are arms, of iron; or they may be a continuation of the shafts G G, securely fastened to the axle at the lower bends and continued downward at an angle of about sixty degrees with the shafts for about eighteen inches. These arms and shafts maybe made from inchand-a-half pipe. Atthe ends of these arms are journal-boxes, which receive the drivingshaft h h, it being of sufficient length to allow pulleys or sprocket-wheels G O to be on a line opposite to the similar ones, 0 0, from which they receive motion through the sprockete chains S S,or their equivalents. On this shaft are also'three driving-pulleys, K K K, each eighteen inches in diameter, one in center of shaft, each of the others respectively about six inches from wheels 0. These pulleys are connected with similar ones, L L L, twelve or thirteen feet distant, by the driving-belts J J J, three or four inches wide. The four outer pulleys, L L K K, have narrow rim-flanges on outer edges. Fastened from outside belt to outside belt,

and continuous all around, is an endless apron of canvas, I I I 1, across which, and fastened securely to the belts, are lateral rows of slats N N NN, about one foot apart, and extending all around the apron. From these slats project teeth about six inches long and same distance apart, which teeth are to take the hay from the rake and carry it to the wagon. The upper end of this apron is held in place and adjusted to desired heights by means of the adjustable lever-bars O O, which are of Wood, about seven and one-half feet long and two by four inches wide. At the upper ends of these bars are fastened journal-boxes, in which the shaft of pulleys L L L runs. These leverbars are pivoted by bolt in the forked ends' of supporting-fulcrums M M, which are of iron, about three feet hi gh,and fastened to the shafts G G of rake. At the other ends of these 1evers O O are attached ratchet-bars P P, whose teeth are held by detents fastened to the shafts at ff, and which permit the operator on the receiving-wagon to elevate the upper end of the endless apron, as desired.

R is the hay or receiving wagon, to the hind axle of which the shaft or shafts of the rake are secured by hook T or any equivalent devices. These shafts G Gr bear outwardly from where fastened to axle until proper position for supports M M is reached-that is, leaving about two and one-half feet from supports to ratchet-bars P P, and then bend toward each other until they meet at proper length to reach axle of wagon at T.

m m is a brace between shafts at widest part, to give more rigidity to the frame.

The operation of the combined machine is obvious. When set in motion, the clutches b I) being in lock with sprocket-wheels O O, the endless apron is set in motion, and the hay is continuously carried from the teeth of the rake by the small teeth on apron-slats and delivered into the wagon.

What I claim, and desire to secure by Letters Patent, is

. 1. In a horse-rake and hay-loading machine, the combination, with the driving-wheels A, having extended hubs Z, sprocket-wheels 0, formed with clutch-teeth on their inner edges, clutch-rings I), pins 0, springs c, and featherkeys a a, of the levers d, arms 02, pins e, rakehead D, lever H, and bent axle B, as shown and described.

2. In a combined horse-rake and loadingmachine, in which the rake has a bent axle, the combination of lever H, striking plate or hook z, cord j, having a knot or button, 9, and pulley k, substantially as described, and for the purposes set forth.

3. In a combined horse-rake and loadingmachine, the combination of the shaft or pole G, supporting-fulcrum M, and lever 0, having a ratchet-bar, 1?, secured at its short end, substantially as described, and for the purposes set forth.
