whichy separates the table from `the rake-stand;

.lhs my improvements relate only to the l( `means for operating and directing the move-A ments'of the rake-arms, the other parts ofthe machine may be constructed in any of the well-known ways in use.

The circular camway or track which the rollerstraverse in supporting and guiding the rake-arms consists of three parts, viz: rst, an elevated portion, G, on the side next to the driver, for elevating the rake-arms, so as io cause them to avoid the drivers head during this portion of their movement, as shown in dotted lines at the right of Fig. I 5 secondly, an upwardly-inclined portion, G1, which elevates the rakes after they have 'performed their reeling action, so as to cause them to pass over the grain as it is being collected on the table, as shown in dotted lines at the left in Fig. I; and, thirdly, an outer horizontal branch track, G2, on which the. rollers travel during the sweeping-0E movement of the rakes.

The portions GGl are arranged and inclined inthe usual manner, the latter being' made stationary instead of movable, as in most of the other devices in use. Both of the tracks Gl and G2 unite with the portion G, which forms a continuation thereof, as shown in Figs. II, III, and IV. Y

H is the roller, moiuited in any suitable bearing, I, which is connected vwith the shank of the rake-arms D, either by means of aloose sleeve, I', as shown in Fig. VI, or by means of a bolt, 1', passing up through a slot, d, in the arm, as shown in Figs. I and II, so as to permit ofthe bearing sliding back and forth along the arm for changin g the position of the roller.

J is the shifting-bar, arranged so as to slide horizontally in standards k 7c .from the rakestand. It is arranged under the portion G of the track, with its inner endpointing toward the forward end of the track G1, so that when it is thrust forward its beveled end will be iiush with the outer edge of the track and form a guide, against which the inner bearing of the roller will strike as the latter approaches the track G, and thus force out the bearing ,along the rakearm, and shift the roller into the outer horizontal track G2, as shown in Fig. I, and in dotted lines, Fig. III.

The shifting-bar is provided with a recoilspring, l, which, after the roller has been shifted, brings the bar back to its normal position, as shown. This bar, instead of being arranged as above described, may be pivoted, as shown at M, Fig. V, and operate as a lever, as represented in dotted lines in the same figure.

N is the spring-guard, consisting `of a rod or bar attached to the edge of the track G, and extending concentrically with the track till it reaches, or nearly reaches, the forward end of the elevated track Gl, so as to form an outer guard or guide to direct the roller onto said track G1, as represented in Figs. II and IV.

Vhen a gavel is required to be raked ofi", the shifting-bar J is thrust forward by the driver by any suitable means, as an arm or lever, which guides the roller into the' outer and horizontal track G2, the elasticity of the guard N permitting it to spring outward for the passage of the roller, as represented in dotted lines, Fig. III. As the roller passes into this track G2, some means for holding the rake-arm down to its work becomes necessary. For this purpose I provide the upper edge of the fender F with an inwardly-projecting flange, f, and the outer bearing of the roller with an outwardly-projecting pin or lug, o, arranged so as to pass under said iian ge, which thereby prevents the arm rising duringthe raking-of movement.

Instead of constructing the fender with the iange f, a rod or bar having its ends secured to the outer edges of the camway, and otherwise braced and supported, may be employed.

In order to insure the rollers keeping on the track, I prefer to provide the elevated track Gl with a groove for the roller to run in, and the portion G with a ledge or iiange on each edge to retain it thereon.

Each of the rakearms may be provided with a spring, p, which operates to prevent the arm, when it hasv arrived at a nearlyn vertical position, from remaining in that position after they have passed the crown of the camway, when they should begin to decline.

IVhat I claim. as my invention isl. The roller H, when provided with sliding bearings I, arranged with the rake-arm D and tracks G G2, and operating substantially as hereinbefore set forth.

2.' The combination of the shifting-bar J with adjustable roller H and tracks G GI G2, substantially as and for the purpose hereinbefore set forth. v i

3. The spring-guard N ,I arranged with the camway G G1 G2, and combined and operating with the adjustable roller H and shifting-bar J, substantially as hereinbefore'set forth. A 4. The combination, with the laterally-adjustable roller H, of the projection o and flanged guard f, as hereinbefore speciied.
