HARROW.
SPECIFICATION forming part of Letters Patent No. 767,890, dated August 16, 1904. Application filed December 30, 1903. Serial No. 187,179. (No model.)
To all whom it may concern:
Be it known that I, GEORGE W. HOYLE, a citizen of the United States, residing at Cloverdale, in the county of Sonoma and State of California, have invented newand useful Improvements in Harrows, of which the following is a specification.
My invention relates to improvements in harrows, more particularly the rotary type.
It has for its object, among other things, to effectively and expeditiously pulverize or comminute the clods of plowed ground and yet leave the ground loose in the path of the barrow, while by making minor changes the harrow may be adapted to serve in the capacity of a cultivator or a plow, as occasion may require.
Said invention consists of the combination of parts, including their construction and arrangement, substantially as hereinafter more fully disclosed, andspecifically pointed, out by the claim concluding the following specification.
In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure l is a plan view thereof. Fig. 2 is an enlarged detailed end view disclosing more especially one of the pulveriZer-roller-shaft bearings and frame-side-bar supports. Fig. 3 is a lateral view of said part or bearing and support. 7
In carrying out my invention I construct a carrying-frame 1 preferably of metal with the sideor lateral bars l thereof extending, say, from the extreme rear end of the machine or harrow forward a suitable distance, then inclined or converged inward, as at 1 the convergent portions being further extended forward, but parallel, as at 1, to receive, and between which is secured, the tongue 2, the usual hammer-strap being provided therefor.
Lateral braces 3 of metal are secured at their ends to the inclined or convergent portions 1 and to the parallel extenslons l ,'respectlvely, as shown. Corresponding sections 1 1 are provided for forming the forward and rear end portions or bars of said carrying-frame, the former having inturned end portions or terminals 1 suitably secured to said lateral bars upon their inside and the latter having forward-extended terminals 1 secured to the outside of said lateral bars.
A roller 4, which may be of cylindric log or metal construction and, if of the former, bound or encompassed at the ends by metal bands, is suitably journaled in or carried by the frame 1, as presently disclosed, and equipped with a plurality of rows of substantially diamond-pointed teeth or shovels 6, adapted to be screwed into said roller in its periphery and having their points flattened, said teeth or shovels being preferably ofsoft steel in the main and tipped with hard steel. The teeth or shovels of successive rows alternate each other throughout, as shown, and are adapted to-efieotively or thoroughly pulverize or com- 'minute all clods turned up in plowing the ground, and yet as the tooth-carrying roller passes over the surface leaving the ground loose, as desired. Said roller has suitably inserted or secured in its ends journals 6, angular or square in cross-section where they are contained within said roller and having keyed thereon, as at 6, collars 7, said collars being embedded into the ends of said rollersay to the dotted line 7 while that portion of each roller beyond said line extends outside of said roller, thus providing for offsetting the ends of said roller from the boxing (next described) carrying or receiving the journals.
A boxing 8 for receiving each end of the journals 6, as above noted, has passed vertically therethrough and suitably held thereto, as shown, duplicate spaced-apart yokes 8 for suspending said boxing from the frame 1, the looped or bowed portions of said yokes encompassing the lateral bars 1 of the latter. Said lateral'bars l have each a vertical recess or notch 8 in its upperedge to receive the lower edge of the loop of each yoke, as shown, while each boxing has in its upper edge also a vertical slot or recess 9 to receive the lower edge of each lateral bar 1, whereby said yoke and boxing are held against longitudinal displacement or movement upon said bars and yet providing for the ready attachment of the boxing and roller-journals to the latter and equally so the removal of said parts therefrom, as desired. Said boxing or boxes are so disposed with relation to the lateral bars of the frame 1 as that each stands with about half of its cross-section upon the inside of each of said lateral bars, said latter portion or half of said boxing abutting or contacting with the collars 7, secured upon the journals of said roller, thus preventing endwise or lateral movement of said roller.
It is understood that latitude is allowed herein as to details, as they may be changed as circumstances suggest without departing from the spirit of my invention and the latter yet be protected.
Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is
GEORGE- W. I-IOYLE. Witnesses:
