WILLIAM A. GILLENTINE, OF ALEXANDER, TEXAS.
LEVER.No. 862,468.
Specification of Letters Patent.
Application filed October 17, 1906. Serial No, 339,407.To all whom it may concern:
Be it known that I, WILLIAM A. GILLENTINE, a citi-
zen of the United States, residing at Alexander, in the
county of Erath and State of Texas, have invented new
5 and useful Improvements in Levers, of which the fol-
lowing is a specification.
This invention relates to levers of the pawl and
ratchet type designed especially for use in adjusting
movable cultivator gangs but which may obviously be
10 employed in connection with a variety of other mech-
anismns for operating a movable relative to a fixed part.
The invention has for its objects to provide a com-
paratively simple, inexpensive device of this character
which may be readily installed for use, one wherein the
15 movable part may, through the medium of the operat-
ing lever, be conveniently shifted in either direction,
and one wherein the locking pawls will, through en-
gagement with the ratchet, securely lock the lever
against movement but may be conveniently operated
20 at will to release the lever.
With these and other objects in view, the invention
comprises the novel features of construction and com-
bination of parts more fully hereinafter described.
In the accompanying drawings: Figure 1 is a rear
25 elevation of a lever.embodying the invention and show-
ing the same locked against movement. Fig. 2 is a side
elevation of the same.
Referring to the drawings, I designates a segmental
rack comprising an upper arcuate portion or bar 2 pro-
30 vided with teeth 3 and a body 4 having a downwardly
extending shank 5 terminating at its lower end in a
forwardly extending bearing portion or flange 6 adapted
in practice for attachment to a fixed part or base 7 on}
which the ratchet is mounted.
35 Pivoted at a point adjacent its lower end to the body
portion 4 of the ratchet and by means of a horizontal
pintle 8 is an operating lever 9 having at its upper end
a handle 10, and at its lower end an integral, forwardly
extending engaging portion or pin 11 adapted for piv-
40 otal engagement with a movable part 12, to be actuated
by the lever, there being struck from the body portion
of the lever a bearing lip 14 bent upward at the rear
face of the lever into engagement with the arched por-
tion 2 of the ratchet for guiding the lever in its move-
45 ments relative to the latter.
Pivoted as at 15 to the lever at a point above the
ratchet is a pair of reversely disposed locking pawls 16
adapted for engagement with the teeth 3 to lock thePatented Aug. 6, 1907.
lever against movement in either direction, the pawls
being maintained in engaging position under the action 50
of an inverted; substantially V-shaped spring 17 having
the lower ends of its side portions, which tend to move
toward each other, pivoted respectively to the pawls,
while pivoted to the lever 9 at a point adjacent the
handle 10 is a movable grip piece or lever 18 engaged 55
with the upper end of a connecting member or rod 19
engaged at its lower end with the upper looped end of
the spring 17.
In practice, the pawls 16 normally engage the ratchet
for locking the lever against movement being pressed 60
to engaging position under the action of spring 17, un-
der which conditions the part 12 will, of course, be
held against movement. When it is desired to shift the
part 12 in either direction, the handle 10 and grip piece
18 are grasped and the latter pressed inwardly thereby 65
exerting traction on the connecting rod 19 for lifting the
pawls 16 through the medium of spring 17 out of en-
gagement with the ratchet, whereupon the lever may,
of course, be rocked on its fulcrum for actuating the
part 12. 70
Having thus described my invention, what I claim is:
1. In a device of the class described, a ratchet adapted
for engagement with a fixed part, a lever pivoted between
its ends to the ratchet and adapted for engagement at its
lower end with a movable part, a bearing lip provided on 75
the lever for engagement with a portion of the ratchet to
guide the lever in its movements a pair of reversely dis-
posed pawls pivoted to the lever, a spring common to and
for moving the pawls to engaging position, and means for
throwing the pawls out of engagement with the ratchet. 80
2. In a device of the class described, a fixed ratchet hav-
ing a toothed portion, a lever fulcrumed between its ends
on the ratchet and provided with a bearing lip adapted for
engagement with said toothed portion to guide the lever in
its movements, a pair of reversely disposed pawls pivoted 85
to the lever for engagement with the ratchet, a substan-
tially V-shaped spring common to and for moving the
pawis to engaging position, and means engaged with the
spring for moving the pawls to releasing position.
3. In a device of the class described, a toothed ratchet, 90
a lever fulcrumned between its ends on the ratchet, a pair
cf pawls pivoted to the lever and adapted for engagement
with the ratchet, a substantially V-shaped spring common
to and for moving the pals to engaging position, a mov-
able grip piece attached to the lever, and a connecting rod 95
engaged with the grip piece and spring.
In testimony whereof, I affix my signature in presence
of two witnesses.
