LAND ROLLER.

LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 594,238, dated November 23, 1897.

Application filed May 6, 1897.

T0 ctZZ whom it may concern:

Be it known that I, JOSEPH A. FISHER, a citizen of the United States, residing at Christiansburg, in the county of Montgomery and State of Virginia, have invented certain new and useful Improvements in Land-Rollers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to land-rollers; and the object is to simplify the construction and provide a device of this character which will perform its work in an effective manner and which may be constructed and placed upon themarket at small cost. 7

With this object in View the invention consists of certain features of construction and combination of parts, which will be hereinafter fully set forth and claimed.

In the accompanying drawings, Figure l is a top plan view of my improved land-roller. Fig. 2 is a cross-sectional view on the line 0000 of Fig. 1. Fig. 3 is a perspective view of one of the journal-blocks, and Fig. 4 is a similar View of one of the stud-axles.

In the drawings, 1 denotes the frame of the machine, which is preferably rectangular in form, consisting of the side pieces 2, the forward and rear cross-pieces 3 and 4, respectively, and the intermediate cross-piece 5.

The side pieces 2 are provided with journal-boxes 6, which support the stud-shafts 7, secured in the outer ends of the land-rollers 8. These rollers may be made of wood or a composition of cement and sand.

To prevent the stud -shafts withdrawing from the rollers, I take the inner ends of the shafts and provide them with outwardly-directed barbs, so that it will be impossible to remove the shafts when secured in position whether the roller is made of wood or a composition of sand and cement.

To support the inner or adjacent ends of.

the rollers, I bolt to the cross-pieces 4 and 5 an iron bar 9, which has projecting from its opposite sides intermediate its ends two studshafts 10. The inner ends of these rollers are fitted with journal-blocks 11, preferably Serial No. 635 ,340. (N0 model) angular in cross-section, and the outer ends of these blocks are of less area than the inner ends, so that if the rollers are made of a composition of sand and cement and the blocks molded in their inner ends it would be impossible for said blocks to withdraw or become loosened. It is of course understood that when these blocks are used with wooden rollers the rollers are made of longitudinal sections that are clamped around said blocks. These blocks are formed with journal-bearings and receive the ends of the stud-shafts 10, and thus permit the rollers to have a free rotary motion without the liability of their pulling away from their bearings.

12 denotes a tongue which is bolted to the cross-pieces 3 and 5 and has pivoted to it the doubletree 13, connected to the cross-piece 5 by chains 14 and having linked to its ends singletrees 15. The forward end of the tongue is provided with a yoke or spreader 16 and the rear end of the tongue is provided with a spring-seat 17.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of the invention will be apparent without requiring fur ther explanation. It is exceedingly simple, strong, and durable and can be manufactured at such a small cost as to be within reach of farmers of all classes of life.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

In a land-roller, the combination with a supporting-frame, of land-rollers arranged end to end, an iron bar bolted to the supportingframe and provided intermediate its ends with oppositely-projecting stud-shafts, journal-boXes secured to the side pieces of the frame, stud-shafts journaled in said boxes and having tapering inner ends provided with barbs embedded in the outer ends of the rollers, and journal-blocks, the inner ends of which are of greater area than the outer ends, said blocks embedded in the inner ends of 1 the rollers and provided with journal-bearings to receive stud-shafts of the aforesaid bar, substantially as set forth.

JOSEPH A. FISHER.
