HARROW ATTACHMENT.

SPECIFCATION forming part of Letters Patent No. 370,264, dated September 20l 1887- Application filed May 2S, 1887. Serial No. 239,701.

To @ZZ whom, it may concern.-

Be it known that I, CALVIN KEssLER, of Pendleton, in the county of Umatilla and State of Oregon, have invented a new and useful lmprovement in Harrow Attachments, of which the following is a specification.

The object of my invention is to provide an attachment for harrows by means of which the teeth can be cleaned without stopping, and which will serve as runners for transporting the harrow from place to place.

The invention consists of a series of U- shaped perforated bars adapted to be raised and lowered upon the tooth-bars.

The invention also consists in the means for raising and lowering the said bars.

The invention further consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed outin the claims.

Figure l is a plan view of a harrow having my improvement applied. Fig. 2 is a detail side elevation, partly in section, of the frame and the operating mechanism. Fig. 3 is a section on line 3 3 of Fig. 2. Figs.'4 and 5 are detail views.

Similar letters of reference indicate corre spending parts in the several figures.

Referring` to the drawings by letter, A represents a harrow, which may be of any approved construction. The one shown in the drawings consists of the tooth-bars a, the teeth a, and the cross-bars a2, and is provided with the draft attachment a". To the erossbars a2 of the harrow is secured the frame B, consisting of the arms b, secured at their upper ends to an apertured plate b', having downwardlyprojecting lugs b2, the lower ends of the standards being apertured for securing` them to the bars a2.

C are a series of bars, U shaped in cross-seetion and connected to each other by the bars c. The bars C are provided with perforaticns c', corresponding in number to the number of teeth in the bars, and preferably have their ends closed, as shown.

To the inner cross-bars, c, is secured the standard D, which is preferably formed with the arms d, which are secured to the said crossbars c in any suitable manner. The upper end of the standard D is provided with the (No model.)

slots c7. di and works freely in the aperture of the plate b of the frameB, so that the bars C can be raised or lowered as desired. E is a lever pivoted to the standard D at c, and provided with the curved and slotted arm e', projecting through the slot d of the standard D under the plate b. A pin, e2, passes through the lugs b, the slot d of the standard D, and through the slot of the lever E, and is provided with the roller eiin the slot of the standard. Y c

To the side of the lever is secured the springcatch F, which engages with the teeth d3 on the standard D, for locking the lever in position. The spring-catch consists of a bolt, f, working in lugs f on the sides of lever E, and surrounded by a spring, f2, for forcing it forward into engagement with the teeth d, and is dis` engaged therefrom by means of the handlef, pivoted to the lever E and connected to the bolt by the linkf.

By the above-described construction it will be seen that by operating the lever E the bars C can be lowered to clean the teeth of grass or other rubbish, and then raised again without stopping, thereby saving much time and trouble. By lowering the bars, so that the teeth will not project through the apertures thereof, they are made to serve as runners to permit the harrow to be readily transported from place to place.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with a harrow, of U- shaped bars adapted to receive the tooth-bars and perforated' for the passage of the teeth of the said bars, and means for raising and low^ ering said U -shaped bars, substantially as herein shown and described.

2. The combination, with a harrow, of a series of U-shaped bars having closed ends and connected together, the said bars being adapted to receive the tooth-bars and perforated for the passage of the teeth of the said bars, and means for raising and lowering the said U-shaped bars, substantially as herein shown and described.

3. The combination,with a harrow provided with the frame B, having a central aperture, of a series ot' U-shaped and perforated bars,

C, connected together, the standard D, secured with a frame having a central opening, of a series of U-shaped bars into which the toothbars fit, an upwardly-projecting standard secured to the bars and IWorking in the opening 0f the frame carried by the harrow, and an operating-lever pivoted to the said standard and engaging a pin carried by the frame of the harrow, substantially as herein shown and described.

5. The combination, with a barrow and the frame B, mounted thereon and provided with the pin e2, of the Ushaped bars C, the slotted standard D, secured to the said bars and projectin g through the opening in the said fra'rne, the lever E, pivoted to the standard and provided with the curved and slotted arm e,work ing in the slot of the standard, and a spring catch for locking the lever in position, sub- 25 stantially as described.

6. The combination,with aharrow provided with the frame B, having the downwardlyprojecting lugs b2, of the bars C, the standard D, provided with the slots d cl2, the lever E, 3o 4 provided with the curved and slotted arm e', the pin e2, the roller ci thereon, and the springcatch F, substantially as herein shown and described.

7. An attachment for harrows consisting of 3 5 the frame B, adapted to be secured to a harf row, the U-shaped bars C, the slotted standard D, secured to the said bars, and the lever E, having the curved and slotted arm e', and provided with the spring-catch F.- substan- 4c tially as herein shown and described.
