ATENT A. H. GARYL, OF SANDUSKY, OHIO.

Specification forming part of Letters Patent No. l4,l3, dated February 5, 1556.

To all whom it may concern:

Be it known that I, ALEXANDER H. (DARYL, of Sandusky, in the county of Erie and State of Ohio, have invented a new and Improved Raking Attachment to be applied to Reapers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a transverse vertical section of a reaper with my improvement applied to it, 00 m, Fig. 3, showingthe plane of section. Fig. 2 is a longitudinal vertical section of the same, 3 3 Fig. 3, showing the plane of section. Fig. 3 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in the peculiar means employed for operating; the rake, as will be presently shown and described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the main frame of' a reapingmachine. B is the driving-wheel, hung in the frame A, and G is the platform. The main frame and platform are arranged in the usual manner.

0n the main frame and platform there is placed a rectangular framing, D, of a suitable height, as shown clearly in Figs. 1 and 2, and underneath the platform there is placed a rod, E, the ends of which are fitted in grooves a a in the front and back sills of the platform, as shown clearly in Fig. 1, the ends of the rod E being allowed to slide freely in the grooves a a. The rod E has teeth I) attached to it, which teeth, when the rod is moved in a certain direction, extend upward through longitudinal grooves 0 made in the platform 0.

To the rod E a short arm, d, is attached, having a weight, 0, at its end, and underneath the ptatform 0 there is attached a rod or bar, F, the ends of which are bent in right-angular form, so as to form a jog at each end, as shown clearly in the dotted lines in Fig. 3.

To each end of the rod E a chain,f, is attached. These chains, at the outer side of the rod, pass under pulleys g at the outer end of the platform, and then upward over pulleys hat the upper and outer end of the framing 1). The chains then pass over pulleys t at the opposite or inner end of the framing, and are attached to a pulley, G, which isplaccd loosely on the axle H of the driving-wheel B. The chains f, at the opposite or inner side of the rod E, pass underneath pulleys k at the inner side of the platform, and then upward over pulleys Z on the upper part of the framing D, and have a weight, I, attached to them, which weight is placed between the weights j j, attached to the main frame A.

J is a clutch operated by a lever, K. This clutch is of usual construction, and connects at certain times the pulley G with the axle H, as will be presently shown.

To the inner side of the pulley G a pin, m, is attached, and to the outer side an inclined wire, a, is attached, which serves as a cam and acts upon the lever K, as will be presently shown.

To the outer side of the main frame A a vertical lever, L, is attached, which has a spring, 0, bearing against it, as shown in Fig. 1.

The lever K is a spring-lever, and presses upon the outer side of the pulley Gr.

Operation: Suppose the rod E to be at the outer end of the platform 0. When the rod E is in this position the pulley G is notconnected with the axle H, and the pin on is in a recess or notch, 10, in the lever L. As the machine, therefore, is drawn along the rod E will therefore be stationary, as the pulley G does not turn with the axle H, and the teeth I) of the rod E will be in a vertical position and pass up through the grooves c in the platform 0. When a sufficient quantity of out grain is upon the platform 0 the driver pushes forward the upper end of the lever L, and thereby frees the pin m on the the pulley G from the recess or notch 19 in the lever L, and the weight I will consequently descend and the rod E and teeth I) will be drawn quickly from the outer to the inner end of the platform G, and the grain will be raked off the inner end of the platform by the teeth I), which are keptin a vertical position while passing in this direction in consequence of the weight 6 sliding upon the bar F. When, however, the rod E reaches the inner end of the platform, the weight 0 will pass off the jog at the inner end of the bar F, and descend or drop down by its own gravity, and the teeth I) will also fall below the grooves 0, as shown in red, Fig. 2. As the weight I descends the pulley G will of course be turned in a reverse direction to the axle H, the cam at keeping the clutch J free from the pulley G, and when the rod E is brought to the inner end of the platform the cam n will be free from the lever K, so that the clutch J will connect the pulley G with the axle H,and

the pulley G will consequently turn with said' axle, and the weight I will be raised and the rod E, with its teeth depressed, drawn back'to the outer end of the platform, andthe weight 0 will be raised by a spring, q, up through the jog at the outer end of the bar Eupon said bar, and the teeth I) will be in a vertical position and pass up through the grooves a, ready for the return movement when thedriver actuates the lever L. WVhen the rod E reaches the outer end of the platform 0 the pin m on the wheel enters the notch or recess 1) in the lever L, and the weight I and rod E are kept in proper position thereby.

The aboveinvention is extremely simple and operates well. By actuating the rod E and teeth I) by the weight I for raking off the grain from the platform the rake is operated rapidly and the cut grain is swept instantly oft. The return motion is much slower; but a quick speed is not then required, as a certain time must elapse before a quantity of grain sufficient to form a bundle falls upon the platform.

structed like the one herein described have been previously used; but they have been operated by a positive movement from the driving-wheel, and consequently their motion in raking off the cut grain from the platform is too slow. The movement or operation of the rake also is not under the control of the driver, and consequently the platform will be raked off at regular intervals, and sometimes the bundles will be small and at other times large, according to the growthor thickness of the grain.

myimprovement those difficulties are obviated, as the platform may be raked 011" instantaneously at the proper time-thatis, when a sufficient quantity of grain is'upon it.

I do not claim a reciprocating rake placed underneath the platform O, for that has been previously used; but

I ciaim- Operating the rakcthat is, the rod E,provided with teeth b-by means of the weight I and pulley G, the weight and pulley being connected to the rod E by chains f, and otherwise arranged, substantially as shown and described.
