ROBERT G. MOON, OF VILLAGE MILLS, TEXAS.
LOG-CART.
SPECIFICATION forming part of Letters Patent No. 576,464, dated February 2, 1897.
Application filed lee 29, 1896. Berial No, 597,421. (No model.)T'o alfr whonm it 7 ay conceroT.:
Be it known that I, ROBERT G. MOON, a citi-
zen of the United States, and a resident of Vil-
lage Mills, in the county of Hardin and State
5 of Texas, have invented certain new and use-
ful Improvements in Log-Carts; andIdohere-
by declare that the following is a full, clear,
and exact description of the invention, which
will enable others skilled in the art to which
zo it appertains to make and use the same, ref-
erence being had to the accompanying draw-
ings, which form a part of this specification.
My invention relates to improvements in
that class of log-carts in which one end of the
15 log is elevated or drawn up underneath the
axle, while the other end drags along on the
ground.
The object of the invention is to provide an
improved construction of log-cart which shall
20 possess superior advantages with respect to
efficiency in operation.
The invention consists in the novel con-
struction and combination of parts hereinaf-
ter fully described and claimed.
25 In the accompanying drawings, Figure 1 is
a longitudinal sectional view of a log-cart con-
structed in accordance with my invention.
Fig. 2 is a plan view of the same.
In the said drawings the reference-numeral
30 1 designates the axle, 2 the wheels of the cart,
and 3 the hounds, which are connected to-
gether at their front ends by plates 4, having
a space therebetween for the passage of the
sliding tongue 5, the rear end of which works
35 in a slot in the axle and is held in place by a
plate 6.
Secured to the axle, between the rear ends
of the hounds, are beams 7, to which are se-
cured boxes 8, in which are journaled trun-
40 nions 9 of a block 10. This block is four-
sided,and two of its opposite sides are rounded,
one being convex and the other concave, as
seen at 12 and 13, while the other sides are
fiat.
45 The trunnions are secured eccentrically to
the block, that is to say, near one corner at
each end, and at the center, on the convex side,
the block is provided with a post or bar, by
which it may be turned or rotated. Secured
50 to the outer end of said bar is a chain 14, to
the other end of which is secured the sliding
tongue in front of the hounds.The numeral 15 designates a catch pivotally
connected with said bar, which is adapted to
engage under a transverse bar 17, secured to 55
the hounds, and hold the block in place when
it has been turned to elevate a log.. Con-
nected with this catch and the bar is a coiled
spring 16 for forcing the end of the catch un-
der the bar. 6o
Secured to the upper plate 4, at the front
ends of the hounds, are two lugs 18, to which
is secured a rod 19. Pivoted to this rod is a
gravity-dog 21, having its front end turned
down at an angle and adapted to engage with 65
teeth 23 of a rack-bar 24, secured to the
tongue. To the other end of this dog is jour-
naled a roller 20, under which the chain 14
passes.
Pivoted to the bar secured to the block is 70
a pin 25, which is adapted to fall by gravity
when the said bar is turned down to elevate
the log and engage with a slot 26 in the
tongue.
The numeral 27 designates grab-chains se- 75
cured to the block, by which the log is ele-
vated.
The operation is as follows: The block is
turned backward, so that the bar secured
thereto will occupy a perpendicular or verti- 80
cal position, and the beam is hitched to the
tongue. The chains 27 are then connected
with the end of the log to be elevated and
the team started, which will draw the tongue
outward, turning the bar and block and rais- 85
ing up the log. At the same time the dog 21
will engage with the teeth of the rack-bar
and by the pressure of the chain 14 thereon
will relieve the team of the backward strain.
As the chain assumes a horizontal position 90o
the pivoted pin 25 will swing down and en-
gage with the slot 26 in the tongue, and thus
take the strain off the chain when the cart is
moved. The spring-catch will also ,engage
with the transverse bar to hold the bar and 95
block in position.
Having thus fully described my invention,
what I claim is-
1. In a log-cart, the combination, with the
axle, the slidable tongue, the block, the trun- oo
nions and the bar, of the lugs secured to said
tongue, the dog pivoted thereto having its
front end bent downwardly, the roller jour-
naled to the other end of said dog, the chain
