It will be evident that if the length of the crank
arm 4| can be Varied, a greater or lesser number
of ratchet teeth 53 will be engaged by the pawl
44. To accomplish this varying of the crank arm
effective length, a cam 64 is adapted to engage a
rearward extension 65 of the plate 49, as best
shown in Figures 1 and 2. The cam 64 is jour
naled on a short shaft 51 supported in a bracket
68 in side walls 53 of the spreader unit l2. The
cam 64 is of such shape that in various positions
it will provide various distances between the cen
tral shaft 61 and the rearward extension 55 of the
plate 43. Such variable distances will cause the
arm 43 to be inclined with respect to the hori
zontal position shown in Figure l. For instance,
as shown in Figure 5, the distance from the shaft
spreader unit l2. A spring 81 is positioned inter
50 mediate the shoe 82 and the bracket 86 and sur
rounds the rod member 84, thus constantly exert
ing a pressure on the ratchet wheel 1|. The con
tacting of the flat shoe 82 against the flat sur
faces 83 of the ratchet wheel 1| tends to hold
the ratchet wheel in a position wherein these
hat surfaces engage. In other words, it would
be impossible to maintain the cam 64 inits posi
tion, as shown in Figure 4, wherein the shoe 82
is contacting an apex 88 formed by two flat por
tions 83.
Figure 3 shows the cam fixed in the position
shown in Figure 1 with the crank 39 in its upper
most position. During such movement of the
arm 43, the ratchet wheel 46 has advanced its
maximum number of teeth. Figures 5 and 6, as
previously described, show the cam S4 in its posi
