PUSH-RAKE.

SPECIFICATION forming part of Letters Patent No. 709,264, dated September 16, 1902.

Application filed February 1, 1901. Serial No. 45,603. (No model.)

To all whom it may concern: Fig. 8 is a side elevation of the arrangement Be it known that I, HENRY GREEN, a citizen shown in Fig. 6. of the United States, residing at Pekin, in the A indicates the supporting-frame of the county of Tazewell and State of Illinois, have rake, which is supported at the rear end by invented certain new and useful Improvecaster-wheels B B. The rake-head is carried ments in Push-Rakes; and I do hereby declare at the forward end of said frame and consists that the following is a full, clear, and exact of the transverse bars O and D, which carry description of the invention, which will enthe teeth E, as shown.

This projects rearwardly and 50 perspective view of a portion of the same, and a depending lip thereon has a hole through it through which passes the said rod X. This serves to support the fitting and said rod X, so that they will not teeter on the bail. Such an arrangement is not essential to the proper working of the rake, however, and need not he used. A pair of brackets Z are secured to the under side of the bars R and carry a horizontal rod 1, acting as a stop which engages a detent ,2,.notched at 3 and 4, as shown in Fig. 7. The said detent is pivotally held at the lower end of the lever U, as shown in Fig. 8, by means of a clamp composed of the portions 5 and 6, secured together on the said bar 2 by a bolt 7. The bolt 8, which forms the pivotal connection for the links V and the lever, constitutes a pivot for the saiddetent, as shown in said Fig. 8. However, other means may of course be substituted for pivoting this portion. The detent, acting by gravity, engages the said stop 1 by means of its notches, as will be hereinafter more fully described. I provide a foot-lever for releasing the said detent at certain times during the operation of the machine. This lever is illustrated in the several figures, but more fully in Figs. 7 and 8, by the numeral 9. It is rigidly mounted upon a rock shaft 10, journaled in the lower extremities of the brackets z, before referred to. Said rockshaft 10, ata point immediately beneath the detent 2, carries a trip 11, and adjacent to it is a weight 12 to counterbalance the weight of the lever for normally preventing engagement of the. said trip 11 with the detent.

The drivers seat is indicated at 13, being attached to a chair14, which is similar to the chair T and secured in like manner to the bars RR described. Parallel with the bars R R are two guides 15, secured at theirends to the chairs T and 14. These guides prevent the doubletree from raisingfrom the bars R R and preventan endwise' movement thereof by means of a roller 16, carried on a pin 17, secured to the draft-bar at about its middle length. Two convergent bars 18 are secured at the extremities of the draft-bar, the said convergent ends being attached to a link 19, adapted to slide upon a plate 20 on a block 21, secured to a cross-bar 22 of the supporting-frame. A roller 23 on a pin 24, secured to the said plate 20, guides the link and serves to prevent a swinging or pivotal movementofthedraft-barontherollerl6. Theoperation of the rake will now be understood. In raking the teeth E occupy the position indicated in full lines, Fig. 5, the lever U being forward, and at this time the detent 2 is in engagement with the stop 1 by means of its forward notch 3. In this position also the draftbar is locked in its rearward position by said detent. When sufficient load has been taken on, as the rake moves forward the operator places his foot u pon the lever 9 and by pressure raises the said detent from engagement with the stop 1 by means of the trip 11. At the same time he grasps the lever Uand draws it toward him, which, with the forward movement of the draft-bar, due to the pull of the horses,

said bar having been freed by raising the detent, as described, lifts the rake-head to the dotted-line position by drawing the reachesM rearwardly. The movement of the reaches is but slight, since the rake-head merely teeters upon the pivots of the wheels which carry it, for since the weight of the supporting-frame is behind the said wheel-pivots the extreme rear ends of the teeth will be depressed, while the forward portions thereof will rise. Thus it is evident that very little movement of said reaches is necessary. The labor necessary to shift the lever is but slight by reason of the pull of the horses being transferred for the moment from pushing the machine forward to pulling the draft-bar forward and having connection with said lever throws it toward the operator. It is possible to dispense with the hand portion of the lever and merely use that portion thereof which connects the rod X with the draft-bar and let the horses do the entire work. The manner of applying the power of the horses is such as to make this method possible. Therefore when the teeth are to be raised the operator has but to raise the detent 2 by the foot-lever 9 to permit the draft-bar to move forward to accomplish the desired end. When the bar has traveled the full length of its movement or until the raketeeth are carried to' their full height, the gravity-bar 2 has been moved to the dotted line position shown in Fig. 8, and as the notch 4 reaches the stop 1 it drops into engagement therewith and supports the load through the lever U, rod X, reaches M M, bell-cranks J, and links K. When the load is to be delivered, it is only necessary to place the foot upon the lever 9 to raise the trip 11 and lift the detent 2 from the stop 1. When thus released,

the rake-head willfall to its normal position.

The said detent during its movement will travel upon the stop 1 and finally engage it by the notch 3, as shown in Fig. 8, where it remains until anotherload is to be raised. The operation is exceedingly simple and all movements are always under perfect control. The weight 12 for overcoming the weight of the said lever 9 always keeps the trip 11 free of the detent, so that there is no danger of tripping it in either position. The rod X,which, as before intimated, has loose connection with the portion N, permits the rake-head to rise and fall when passing over uneven ground without danger of breaking or disarranging any of the parts of the machine, the hole in the Wall of the said portion being larger than thediameter of the rod .70. Adjustment of the latter rod is had where it connects with the lever U by means of two nuts 25 and 26, by which the rod may be shortened or lengthened to meet requiremenls.

I may make various alterations in my improved rake both as to the arrangement of the parts and the means used. It is obvious that the various parts employed can be substituted by others that will accomplish the same results, and I do not wish to confine myself, therefore, to the eXact construction shown and described. The arrangement of my rake is such that the pull of the horses is utilized to the best advantage for steering it, because the draft-bar during the raking is held firmly, and, as stated at the beginning of the description, the pull of either horse is applied directly to the machine and is not transferred to the opposite horse in a seesawing manner and lost. The operation is thereby made positive, and this is doubly true during the time the load is being raised.

Having thus described my invention, I claim 1. A push-rake consisting of a supportingframe, a rake-head at the forwardend thereof, a lifting mechanism for raising said head, the

same consisting of an unyielding connection pivotally attached to the said rake-head and extending toward the rear of said supportin gframe, a draft-bar at the rearof the said frame the same being slidable thereon, but held rigidly at right angles to the length of the machine at all times and having connection with such rake-head lifting mechanism for raising the rake-head when moved forward by the pull of the horses.
