Abstract 12,367. Slatter, G. June 9. Fastenings, clamp. - The lawn-mower rollers described in Specification No. 18,266, A.D. 1907, [Abridgment Class Agricultural appliances for the treatment of land &c.], are adapted to be secured to fixed cross-bars of various sizes by means of special adjustable clamps. As shown in Fig. 1, the two parts of the clamp are provided with V-shaped grooves to engage the crossbar 6 and are hinged together by a pin passing through one of two holts in a lug 8, a bolt 10 being provided to draw the two parts together. The roller standard 3 is adjustable vertically in a socket 4 forming part of the clamp. In a modification, the two parts of the clamp are hinged together and are provided with replacable gripping-pieces with grooves of various sizes. In another hinged clamp, the two parts are provided with gripping-ribs and are drawn together by a bolt with a rounded T-bead. In another clamp, the two parts are connected by two bolts and are provided with grooves of different sizes to suit different cross-bars. As shown in Fig. 5, the cross-bar 24 is gripped between a fixed jaw 19 on the socket 17 and a loose piece 21 pressed down by a screw 25 in a fixed jaw 20. A pin 23 projects into a recess in the piece 21. In Fig. 7 the movable piece 34 and fixed jaw 32 are shown provided with rounded grooves, the movable piece 34 being adapted to slide along an incline 33 when the bolt 36 is tightened. According to the Provisional Specification the clamp may be in the form of a chain, or may be fitted with two or more set screws, or with a sliding wedge.
