FRALPJEE STRUCTURE FOR ROAD ROLLERS.

Application filed November 21, 1921, Serial No. 516,574.

To all whom it may concern:

Be it known that 1, ANDREW W. AITKEN, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and use ful Improvements in Frame Structures for ltoad Rollers, of which the following is a specification.

My invention relates to frame structures for road rollers.

The object of my invention is to provide a structure of this character of such a nature as will provide a substantial support for the water tank and also a rigid point of attachment for a draw-bar and at the same time be so arranged as to permit the ready removal of the rear axle when desired.

In the accompanying drawings Figs. 1 and 3 represent, when placed together end to end, a top plan view of the st ructure.

Figs. 2 and 4:, when placed together end to end, represent a side elevation of the same.

Fig. 5 is an enlarged vertical sectional view on the line 5-5 of Fig. 1.

Fig. 6 is an enlarged vertical section on the line 66 of Fig. 1.

deferring to the drawings, 1 and 2 represent steel vertically-disposed side plate members, the forward ends of which are projected upwardly and forwardly and carry the head 3 in which is journaled in the usual way the swivelled king post for the forward roller. The upper edge of each of these plates is reinforced by an angle-iron 4, these angle irons being tied together by the bars Riveted to the lower edge of each of these side plates is a channel beam, 6 and 7, these beams being tied together by the channel bars 8 and 9; the bars and the beams being connected together by the angle irons 10. Each of the side plates 1 and 2 has an open ing 11 to receive the bearing for the rear axle these openings being within a short distance of the rear edges of the respective plates, each plate being slotted between the opening and its rear edge as indicated at 11 whereby the axle may be removed when desired.

The channel beams 6 and 7 are extended rearwardly beyond the rear edges of the plates 1 and 2 and have bolted to their rear ends, through the angle irons 12, the water tank 13. The sides 13 of the water tank are extended beyond the front wall thereof, as

indicated at 13 and these extended edges are bolted to the rear ends of the side plates and 2 by bolts 1 1; a stiffening bar 15 being inserted between the heads of the bolts and the extended portions of the tank.

A draw bar 16 of any suitable form is attached to the rear ends of the beams 6 and '7 by the angle irons 17, this draw bar being of nature to receive the draft appliances of scarifying devices, or to which may be hitched any other structure designed to be drawn by the roller.

the construction descrilzied it will be seen that a frame structure is provided which will be of ample rigidity and strength to not only support the operating parts of the roller and the water tank thereof, but also provides a rigid point of attachment for draft appliances so that the tank may be re lieved of the strain which would be otherwise'impressed upon it by the attachment of such appliances directly thereto as has been the custom. It will be seen that in the event it is desired to remove the rear axle, this can be accomplished readily by removing the tankand then the axle through the slotted openings.

Having thus described my invention, I claim 1. In a frame structure of the character described, a pair of vertically disposed side plates, a pair of side beams connected there with, said plates having openings to receive the rear axle, the beams being extended rearwardly beyond the plates, a tank removably supported from the beams and also removably connected with the rear edges of said plates, provision for the attachment of daft appliances to the rear ends of said beams, and means whereby the axle may be removed from said plates when said tank is removed.

2. In a frame structure of the character described, a pair of braced vertically-disposed side plates having openings to re ceive the rear axle with slots leading from. the openings to the rear edges of said plates, channel beams connected to the lower edges of said plates and projecting rearwardly therefrom, and a tank reinovably secured to the rear edges of said plates and also removably connected with the beams at points beyond the rear edges of ,the plates, the rear ends of said beams having provision for the attachment of draft appliances.
