COMPLETE SPECIFICATION.
An Improvement in Land Rollers.
I, EPHRAIM ALPAUGH of the Village of Preston in the County of Waterloo
in the Province of Ontario, Dominion of Canada, Carpenter do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being made to the accompanying drawings, in which :-
Figure 1, is a plane elevation of a roller, embracing my invention.
Figure 2, a transverse section of the same.
Figure 3, is a sectional elevation of one of the cylinders.
Figure 4, is an end elevation of the roller.
The first part of my invention relates to having the several cylinders composing
a land roller, so adjusted that they will readily adjust their outer surfaces to the
plane of the land on which they are used; and that the elevated end of a cylinder
always bears heavier on the ground than its opposite or low end.
The second part of my invention relates to the combination with a land roller of
a frame composed of three parts, and of such peculiar mechanical construction,
that the entire roller can be taken apart or put together without the use of tools,
such as hammer or wrench.
In the drawing, A is the land roller composed generally of two cylinders formed
of iron or other suitable material, S is the shaft, on which the several cylinders are
hung and by which they are drawn.
The shaft S is preferably square or rectangular, passes through the cylinders,
and through the square boxes in the frame.
The cylinders revolve upon the shaft S by means of the bush J, which is circular
at its circumference, and fits into the circular groove G, and having the rectangular
slot P, by means of which the several cylinders are always kept at right angles
with the line of draft, while at the same time they are allowed to rise and fall as
the plane of the earth on which they are moving requires.
The
The hubs H, having the grooves G revolve with the bushes J.
rockers L, L, have their ends secured in the slots P, and have sufficient curve to
rest on the shaft S.
When one end of a cylinder passes over a lump, and is thereby forced upward,
the weight of the shaft S, frame F and F¹, and the additional weights are thrown
upon the high end of the cylinder by the curve of the rocker L, thus giving
greater capacity for crushing lumps and rolling the ground to an even surface.
In order that any cylinder may be allowed to rise or fall at either end, it must
have end play, which is provided for by the frame being made wider than is
necessary to hold the several cylinders when they are all in a straight line. Holding
the cylinders as near to each other at all times as required, is effected by means of
the coil springs S1, S1, being placed upon the shaft S, between the outer hubs H, H,
and the frame F and F¹.
The frame by which the several cylinders are held together and drawn, is
composed of two parts F and F¹. The bands b, b, are fastened to and form part
of the side of the frame marked F, and the bands 6' 6' form part of the side F¹.
By bringing the parts F and F¹ together and inserting the tongue through the
bands b, b, and the two sides of the frame are united. To farther strengthen
the frame, I add the flat bar B, having hooks h, h, on the upper edge and near the
ends, and hooks on its lower edge and as near the tongue as can be. The
bar B lies at the back of frame F and F and the books h, h, and h¹ are turned
forward, and over the edge of the frame. W, W, W, are weights, which may be
hung on the lugs of the frame d, d, when the soil to be rolled requires more weight

page_text: than that of the roller and frame. To take the roller apart for shipping or housing,
pull out the pin, on which the double tree is pivoted, then pull out the tongue,
raise the centre of the frame about one inch, which disengages the hooks h, h, of
the bar B, when the bar will fall off. Then pull parts F and F' off the ends of
the shaft S, pull out shaft S and all parts of the roller are severed and can easily
be handled by one man.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination of the grooved hubs H, revolving on the rectangular bush J,
the rockers L, and shaft S, substantially as and for the purpose hereinbefore set
forth.
2. In combination with the rockers L, and shaft S, the springs S', substantially as
and for the purpose hereinbefore set forth.
3. The combination with a land roller, of the frame composed of parts F and F'
and B, substantially as and for the purpose hereinbefore set forth.
