action is produced are simple and tlie emptying rapid, the teeth coming to the 
ground again with snlRcient rapidity, 'i'here are several commendable points. 
The axle is ot" solid steel, and placed in the centre of the rake ; the machine is 
thus very strong, and there is no tendency in the wheels to work outwards, a 
defect noticeable in all rakes with short axles bolted or fastened to a frame. The 
means by which this self-action is produced are as follows : On the axle, 
inside the travelling wheels, are small wheels, on which are ])laced friction 
bands connected with the frame; when the rake is full, leverage is applied 
to the break bands, they are tightened and become a part of the wheel, and 
travel round, carrying the teeth and load until a sufBcient height is attained. 
The leverage is then released, the breaks cease to bite, and the rake falls 
to the ground. The illustration will explain more clearly the mechanism.

The driver can either ride or walk. If riding the right foot is used to slightly 
depress the actuating lever at the point a, if walking he raises the lever at 6, as 
will be seen by reference to the illustration. This alteration causes the tighten- 
ing of the break-straps and consequent elevation of the rakes. The connecting 
link d is jointed to the foot lever at c, which centre c, when depressed by the 
action of the attendant is coincident with the centre of the axle of the rake, 
consequently the lifting motion of the cradle and tines does not influence it, 
although the lever arms d ande, with the cradle and break bands /, are earned 
forward when the rake is unloaded ; thus, the first lever being depressed, the 
requisite friction is ])ut on the brake bands, through the double-ended lever 
The break bands can be tightened when necessary by the screw link I. 
A capital cott'tr/er's cooking stove is shown by W. Barton, of Boston, whose 
large cooking ranges have attained a considerable reputation. This is an inven-
